Description

La présente invention concerne les récipients équipés de capsules de fermeture comportant une partie de base pourvue d'au moins un orifice de distribution et un couvercle pivotant relativement à la partie de base, la capsule comportant un élément de commande d'ouverture du couvercle.The present invention relates to containers equipped with closure caps having a base portion provided with at least one dispensing orifice and a lid pivoting relative to the base portion, the capsule having a cover opening control member.

La demande de brevet japonais JP 1-66355 divulgue une capsule de fermeture comportant une partie de base comprenant une jupe filetée intérieurement, à visser sur le col du récipient, entourée par une jupe d'habillage extérieure. Un couvercle est articulé sur cette partie de base au moyen d'une charnière comportant une languette formant ressort, permettant d'assister le mouvement d'ouverture du couvercle. Un élément de commande d'ouverture peut coulisser sur la partie de base afin d'agir sur le couvercle et la charnière.The patent application Japanese JP 1-66355 discloses a closure cap having a base portion comprising an internally threaded skirt, to be screwed onto the neck of the container, surrounded by an outer covering skirt. A cover is hinged to this base portion by means of a hinge having a tongue forming a spring, to assist the opening movement of the lid. An opening control member is slidable on the base portion to act on the lid and hinge.

Une telle capsule n'est pas entièrement satisfaisante, notamment du point de vue esthétique, car au repos, lorsque le couvercle est fermé, l'élément de commande d'ouverture fait saillie vers l'avant d'une distance non négligeable.Such a capsule is not entirely satisfactory, particularly from an aesthetic point of view, because at rest, when the lid is closed, the opening control element protrudes forward a significant distance.

La demande de brevet européen EP 0 699 591 divulgue une capsule comportant une jupe extérieure d'habillage qui est interrompue du côté opposé à la charnière pour recevoir l'élément de commande d'ouverture, lequel comporte un poussoir articulé sur la partie de base et un organe de poussée pouvant coulisser dans un renfoncement de la partie de base. L'organe de poussée comporte des rampes destinées à coopérer avec des reliefs du couvercle pour provoquer le soulèvement de celui-ci ainsi qu'une extrémité destinée à agir sur la languette formant ressort de la charnière. L'organe de poussée comporte une découpe oblongue dans laquelle est engagé un embout de distribution. Une telle découpe est susceptible de favoriser l'accumulation des salissures, de même que le renfoncement dans lequel coulisse l'organe de poussée.The patent application European EP 0 699 591 discloses a capsule having an outer trim skirt which is interrupted on the side opposite the hinge to receive the opening control member, which comprises a pusher hinged to the base portion and a pusher member slidable in a recess of the basic part. The thrust member has ramps for cooperating with reliefs of the cover to cause the lifting thereof and an end for acting on the spring tab of the hinge. The thrust member comprises an oblong cut in which is engaged a dispensing nozzle. Such cutting is likely to promote the accumulation of dirt, as well as the recess in which slides the thrust member.

La demande de brevet français FR 2 685 294 divulgue une capsule de fermeture de fonctionnement assez proche et susceptible de présenter les mêmes inconvénients.The patent application French FR 2 685 294 discloses a closure capsule operating close enough and likely to have the same disadvantages.

Le brevet US 6 834 769 décrit un récipient comportant une capsule de fermeture dans laquelle l'élément de commande d'ouverture coulisse à l'intérieur de la partie de base. L'élément de commande d'ouverture comporte une partie saillante, du côté opposé à la charnière, sur laquelle l'utilisateur doit appuyer pour ouvrir le couvercle. L'élément de commande d'ouverture doit être réalisé sous la forme d'une pièce rapportée, ce qui se répercute sur le coût de fabrication. De plus, la surface d'appui offerte à l'utilisateur est relativement faible, ce qui peut nuire au confort d'utilisation.The patent US 6,834,769 discloses a container having a closure cap in which the opening control member slides within the base portion. The opening control member has a projecting portion, on the side opposite the hinge, on which the user must press to open the lid. The opening control element shall be in the form of an insert, which has an impact on the manufacturing cost. In addition, the support surface offered to the user is relatively small, which can affect comfort of use.

La demande de brevet européen EP 1 281 628 décrit une capsule de fermeture de réalisation similaire.The patent application European EP 1 281 628 discloses a closure cap of similar embodiment.

Il existe un besoin pour bénéficier d'une capsule de fermeture pouvant être réalisée facilement par moulage de matière plastique, qui soit esthétiquement plaisante, facile à utiliser et qui réduise le risque d'accumulation de salissures.There is a need to benefit from a closure cap that can be easily made by plastic molding, which is aesthetically pleasing, easy to use and reduces the risk of accumulation of dirt.

L'invention a pour objet, selon l'un de ses aspects, une capsule de fermeture comportant une partie de base pourvue d'au moins un orifice de distribution, à fixer sur un corps de récipient, un couvercle pivotant et un élément de commande d'ouverture du couvercle, capsule dans laquelle l'élément de commande d'ouverture comporte une jupe entourant une portion au moins de la partie de base et reliée à celle-ci par au moins un élément de liaison élastiquement déformable.The object of the invention is, according to one of its aspects, a closure cap comprising a base part provided with at least one dispensing orifice, to be fixed on a container body, a pivoting lid and a control element. opening of the lid, wherein the opening control element comprises a skirt surrounding at least a portion of the base portion and connected thereto by at least one elastically deformable connecting element.

La jupe de l'élément de commande d'ouverture peut faire office de poussoir pour permettre à l'utilisateur de commander l'ouverture tout en dissimulant la partie supérieure du corps du récipient sur lequel la capsule est montée. La jupe peut offrir une surface d'appui relativement grande à l'utilisateur, ce qui accroît le confort à l'utilisation.The skirt of the opening control member may act as a pusher to allow the user to control the opening while concealing the upper body of the container on which the capsule is mounted. The skirt can provide a relatively large support surface to the user, which increases comfort in use.

Le ou les éléments de liaison élastiquement déformables peuvent agir dans un exemple de mise en oeuvre de l'invention comme un moyen de rappel élastique pour rappeler la jupe dans sa position initiale après l'actionnement par l'utilisateur.The one or more elastically deformable connecting elements can act in an exemplary implementation of the invention as an elastic return means for returning the skirt to its initial position after the actuation by the user.

Enfin, la capsule peut être réalisée de manière à réduire le risque d'accumulation de salissures, grâce par exemple à l'absence de découpe entourant extérieurement l'orifice de distribution et à la possibilité d'absence de renfoncement extérieur de guidage de l'élément de commande d'ouverture similaire à ceux de l'art antérieur.Finally, the capsule can be made in such a way as to reduce the risk of accumulation of dirt, thanks for example to the absence of cutouts surrounding the dispensing orifice externally and to the possibility of absence of an external guide recess of the opening control element similar to those of the prior art.

Dans un exemple de mise en oeuvre de l'invention, la capsule est moulée entièrement en une seule pièce, grâce à la présence du ou des éléments de liaison élastiquement déformables. Le ou les éléments de liaison déformables autorisent la disposition des différentes parties de la capsule dans une configuration facilitant le moulage et peuvent se déformer ensuite lors du montage de la capsule sur le corps du récipient pour prendre leur configuration définitive.In an exemplary implementation of the invention, the capsule is molded entirely in one piece, thanks to the presence of or elastically deformable connecting elements. The deformable connecting element or elements allow the different parts of the capsule to be arranged in a configuration that facilitates the molding and can then deform when the capsule is mounted on the body of the container in order to take their final configuration.

Dans un autre exemple de mise en oeuvre de l'invention, l'élément de commande d'ouverture n'est pas monolithique avec la partie de base.In another exemplary implementation of the invention, the opening control element is not monolithic with the base part.

L'élément de commande d'ouverture et la partie de base peuvent être réalisés séparément puis assemblés. La partie de base et l'élément de commande d'ouverture peuvent être réalisés dans un même moule de manière à permettre leur assemblage lors du démoulage de la capsule.The opening control element and the base part can be made separately and then assembled. The base portion and the opening control element may be made in the same mold so as to allow their assembly during demolding of the capsule.

Dans un exemple de mise en oeuvre de l'invention, la capsule comporte deux éléments de liaison élastiquement déformables reliant la jupe formant poussoir à la partie de base.In an exemplary implementation of the invention, the capsule comprises two elastically deformable connecting elements connecting the pusher skirt to the base portion.

Les éléments de liaison élastiquement déformables peuvent par exemple se raccorder à une extrémité à la jupe de l'élément de commande d'ouverture et à l'autre extrémité à une portion de la partie de base servant au montage de celle-ci sur un col du récipient.The elastically deformable connecting elements may for example be connected at one end to the skirt of the opening control element and at the other end to a portion of the base portion for mounting it on a collar. of the container.

Les éléments de liaison déformables se présentent par exemple chacun sous la forme d'un bras présentant une forme non rectiligne, notamment ondulée.The deformable connecting elements are for example each in the form of an arm having a non-rectilinear shape, particularly corrugated.

Dans une variante de réalisation, les éléments de liaison élastiquement déformables viennent au contact de la partie de base tout en pouvant glisser à son contact lorsque l'utilisateur appuie sur l'élément de commande d'ouverture.In an alternative embodiment, the elastically deformable connecting elements come into contact with the base part while being able to slide in contact with it when the user presses on the opening control element.

Les éléments de liaison peuvent se raccorder chacun à deux extrémités opposées à une portion de l'élément de commande d'ouverture. Les éléments de liaison peuvent comporter deux portions incurvées ayant des concavités dirigées l'une vers l'autre, ces portions incurvées étant configurées pour s'engager sur la partie de base lorsque l'élément de commande d'ouverture est au repos.The connecting members may each be connected at two opposite ends to a portion of the opening control member. The connecting members may comprise two curved portions having concavities directed toward each other, these curved portions being configured to engage the base portion when the opening control member is at rest.

Lorsque l'utilisateur appuie sur celui-ci, les éléments de liaison peuvent se déformer de manière élastique au contact de la partie de base et assurer ainsi le retour de l'élément de commande vers sa position initiale lorsque l'utilisateur le relâche.When the user presses on it, the connecting elements can deform elastically in contact with the base portion and thus ensure the return of the control element to its initial position when the user releases it.

La jupe de l'élément de commande d'ouverture peut présenter toute forme, adaptée de préférence à celle de la partie supérieure du corps du récipient et par exemple une section transversale circulaire ou oblongue.The skirt of the opening control element may have any shape, preferably adapted to that of the upper part of the body of the container and for example a circular or oblong cross section.

La jupe peut présenter sur la face servant d'appui à l'utilisateur une extension s'étendant vers le bas, engagée dans un renfoncement de forme correspondante du corps du récipient.The skirt may have on the face supporting the user an extension extending downwards, engaged in a recess of corresponding shape of the body of the container.

Dans un exemple de mise en oeuvre de l'invention, les éléments de liaison élastiquement déformables peuvent se raccorder à la jupe de l'élément de commande d'ouverture en des emplacements situés sensiblement à l'opposé l'un de l'autre dans un plan parallèle à l'axe de rotation du couvercle et peuvent également se raccorder à la partie de base en des emplacements sensiblement opposés dans ce plan.In an exemplary implementation of the invention, the elastically deformable connecting elements can be connected to the skirt of the opening control element at locations located substantially opposite each other in a plane parallel to the axis of rotation of the lid and can also be connected to the base portion at substantially opposite locations in this plane.

L'élément de commande d'ouverture peut comporter au moins un relief agencé pour coopérer avec le corps du récipient de manière à ce que le corps du récipient guide au moins partiellement en déplacement l'élément de commande d'ouverture lorsque celui-ci est actionné par l'utilisateur.The opening control element may comprise at least one relief arranged to cooperate with the body of the container so that the body of the container at least partially guides the displacement of the opening control element when it is operated by the user.

La paroi supérieure du corps du récipient peut notamment présenter une forme épaulée définissant au moins une surface de guidage et mieux deux surfaces de guidage opposées, le long desquelles peut se déplacer l'élément de commande d'ouverture.The upper wall of the body of the container may in particular have a shouldered shape defining at least one guide surface and better two opposite guide surfaces, along which the opening control element can move.

Dans un exemple où le corps du récipient présente en section transversale une forme oblongue, allongée selon un grand axe, les deux surfaces de guidage précitées peuvent être réalisées de part et d'autre du col en étant orientées dans une direction sensiblement perpendiculaire à ce grand axe.In an example where the body of the container has an elongate oblong shape in elongated cross section along a major axis, the two aforementioned guide surfaces can be made on either side of the neck while being oriented in a direction substantially perpendicular to this large one. axis.

Le col du récipient peut comporter au moins un relief de positionnement angulaire de la partie de base de la capsule relativement au corps du récipient. Ce relief peut par exemple se présenter sous la forme d'une nervure s'étendant au moins partiellement le long du col, par exemple sensiblement symétriquement relativement à un plan médian perpendiculaire à l'axe de rotation du couvercle. La partie de base de la capsule peut comporter par exemple au moins une encoche dans laquelle la nervure précitée peut s'engager lors du montage de la partie de base sur le corps du récipient.The neck of the container may comprise at least one angular positioning relief of the base portion of the capsule relative to the body of the container. This relief may for example be in the form of a rib extending at least partially along the neck, for example substantially symmetrically relative to a median plane perpendicular to the axis of rotation of the lid. The base portion of the capsule may comprise for example at least one notch in which the aforementioned rib can engage during assembly of the base portion on the body of the container.

La fixation de la partie de base sur le corps du récipient peut s'effectuer par encliquetage, dans un exemple de mise en oeuvre de l'invention. La partie de base peut comporter, sur sa surface radialement intérieure, au moins un relief destiné à s'encliqueter sur un relief correspondant réalisé sur le col, à proximité de sa base, par exemple.Fixing the base part on the body of the container can be done by snapping in an exemplary implementation of the invention. The base portion may comprise, on its radially inner surface, at least one relief intended to snap on a corresponding relief made on the neck, near its base, for example.

La partie de base peut comporter une lèvre annulaire d'étanchéité destinée à s'appliquer sur la surface radialement intérieure du col.The base portion may include an annular sealing lip for application to the radially inner surface of the neck.

La jupe de l'élément de commande d'ouverture peut être prolongée, notamment en partie supérieure, par un retour vers l'intérieur.The skirt of the opening control element can be extended, especially in the upper part, by a return to the inside.

Dans un exempte de mise en oeuvre de l'invention, les éléments de liaison se raccordent à leurs extrémités à ce retour et s'étendent par exemple sensiblement dans un même plan.In an embodiment of the invention, the connecting elements are connected at their ends to this return and extend for example substantially in the same plane.

La partie de base comporte, dans un exemple de mise en oeuvre de l'invention, un plateau venant recouvrir au moins partiellement ce retour lorsque la capsule de fermeture est en place sur le récipient.The base portion comprises, in an exemplary implementation of the invention, a plate that covers at least partially this return when the closure cap is in place on the container.

Dans un exemple de mise en oeuvre de l'invention, lors de la fabrication de la capsule, le plateau et le retour peuvent être moulés écartés l'un de l'autre, par exemple d'une distance supérieure ou égale à 4 mm, ce qui peut permettre d'améliorer la résistance mécanique du moule, voire à 5 mm, grâce à la présence du ou des éléments de liaison déformables et ce ou ces derniers autorisent ensuite un mouvement axial du plateau relativement à l'élément de commande d'ouverture lors de la fixation sur le corps du récipient. Une fois la capsule de fermeture en place sur le corps du récipient, le plateau peut ne comporter qu'un jeu de l'ordre de 0,2 mm à 0,5 mm avec le retour, de manière à maintenir axialement la jupe en place tout en lui permettant de se déplacer vers la charnière lorsque l'utilisateur exerce une poussée dessus.In an exemplary implementation of the invention, during the manufacture of the capsule, the plate and the return can be molded apart from each other, for example by a distance greater than or equal to 4 mm, this can make it possible to improve the mechanical strength of the mold, even to 5 mm, thanks to the presence of the deformable connecting element or elements and this or these latter then allow an axial movement of the plate relative to the control element of the mold. opening when fastened to the body of the container. Once the closure cap is in place on the body of the container, the plate may have only a clearance of the order of 0.2 mm to 0.5 mm with the return, so as to maintain the skirt axially in place while allowing it to move towards the hinge when the user pushes on it.

Dans la configuration de moulage, le ou les éléments de liaison élastiquement déformables se présentent par exemple sous la forme de bras ayant une forme ondulée, comme indiqué précédemment, et ces bras peuvent s'étendre par exemple selon un plan sensiblement perpendiculaire à l'axe de la portion de la partie de base servant au montage sur le récipient. Lors de la mise en place de la capsule de fermeture sur le récipient, ces bras peuvent se déformer et s'étendre obliquement vers le corps du récipient une fois la partie de base fixée sur le col.In the molding configuration, the elastically deformable connecting element or elements are for example in the form of arms having a corrugated shape, as indicated above, and these arms can extend for example in a plane substantially perpendicular to the axis of the portion of the base portion for mounting on the container. When placing the closure cap on the container, these arms can deform and extend obliquely to the body of the container once the base portion attached to the neck.

Dans une variante non illustrée, les éléments de liaison déformables sont rectilignes. Dans ce cas, le jeu entre le plateau et le retour lors du moulage est plus faible, étant choisi par exemple en fonction du module d'élasticité du matériau dans lequel les éléments de liaison sont moulés.In a variant not shown, the deformable connecting elements are rectilinear. In this case, the clearance between the plate and the return during molding is lower, being chosen for example according to the modulus of elasticity of the material in which the connecting elements are molded.

Dans un autre exemple de mise en oeuvre de l'invention, les éléments de liaison sont moulés de manière à pouvoir être amenés à s'encliqueter sur la partie de base lors du démoulage de la capsule.In another embodiment of the invention, the connecting elements are molded so as to be able to be snapped onto the base portion during demolding of the capsule.

Le couvercle peut être moulé avec la partie de base ou rapporté sur celle-ci.The lid may be molded with or attached to the base portion.

Dans un exemple où la partie de base et l'élément de commande d'ouverture sont moulés d'une seule pièce, le couvercle peut être moulé avec la partie de base ou rapporté sur la partie de base et fixé sur celle-ci par exemple par encliquetage.In an example where the base part and the opening control element are molded in one piece, the lid can be molded with the base part or attached to the base part and fixed on it for example by snapping.

Dans un exemple où l'élément de commande est assemblé avec la partie de base, par exemple lors du démoulage, le couvercle peut être moulé d'une seule pièce avec la partie de base.In an example where the control element is assembled with the base part, for example during demolding, the lid can be molded in one piece with the base part.

La charnière reliant le couvercle à la partie de base comporte avantageusement au moins une languette formant ressort, laquelle permet d'assister le mouvement d'ouverture du couvercle. Cette languette peut être coudée, et passer par un état de contrainte maximale lorsque le couvercle est dans une position intermédiaire entre la position fermée et la position ouverte.The hinge connecting the lid to the base portion advantageously comprises at least one spring tongue, which can assist the opening movement of the lid. This tongue can be bent, and go through a state of maximum stress when the lid is in an intermediate position between the closed position and the open position.

L'élément de commande d'ouverture est avantageusement agencé pour agir sur la languette formant ressort, lorsqu'actionné par l'utilisateur, en poussant cette languette jusqu'au point de déclenchement de l'effet ressort.The opening control element is advantageously arranged to act on the spring tongue, when actuated by the user, by pushing this tongue to the trigger point of the spring effect.

L'élément de commande d'ouverture peut comporter, du côté de la charnière, une patte destinée à appuyer sur la languette formant ressort. Cette patte peut présenter une forme d'équerre de manière à pouvoir appuyer sur la languette formant ressort en un emplacement surélevé par rapport à l'axe de rotation du couvercle.The opening control member may comprise, on the hinge side, a tab for pressing the spring tongue. This tab may have a square shape so as to press the spring tongue at a location elevated relative to the axis of rotation of the lid.

L'élément de commande d'ouverture est également avantageusement agencé pour agir directement sur le couvercle lorsqu'actionné par l'utilisateur, afin par exemple de faciliter le désengagement d'un picot d'obturation, porté par le couvercle, de l'orifice de distribution de la partie de base.The opening control element is also advantageously arranged to act directly on the lid when actuated by the user, for example to facilitate the disengagement of a closure pin carried by the cover, the orifice distribution of the basic part.

Dans un exemple de mise en oeuvre de l'invention, l'élément de commande d'ouverture est ainsi agencé pour agir sur un relief porté par le couvercle dans une région de celui-ci située sensiblement à l'opposé de la charnière. Le couvercle peut par exemple comporter une dent sur sa face inférieure, à proximité de son bord opposé à la charnière, et le plateau de la partie de base peut comporter une ouverture permettant à cette dent de coopérer avec l'élément de commande d'ouverture lorsque l'utilisateur appuie sur celui-ci pour le déplacer en direction de la charnière. Le retour précité de l'élément de commande d'ouverture peut par exemple comporter une encoche dans laquelle s'engage la dent du couvercle et le fond de cette encoche peut venir en appui sur une face inclinée de la dent au début du déplacement de l'élément de commande d'ouverture, de façon à provoquer un commencement de pivotement du couvercle.In an exemplary implementation of the invention, the opening control element is thus arranged to act on a relief carried by the cover in a region thereof located substantially opposite the hinge. The cover may for example have a tooth on its underside, near its edge opposite the hinge, and the base portion of the tray may include an opening for this tooth to cooperate with the opening control element. when the user presses on it to move it towards the hinge. The aforementioned return of the opening control element may for example comprise a notch in which engages the tooth of the cover and the bottom of this notch may come to bear on an inclined face of the tooth at the beginning of the displacement of the opening control element, so as to cause a beginning of pivoting of the lid.

Le couvercle peut être agencé de manière à s'étendre, en position fermée et lorsque l'élément de commande d'ouverture est au repos, en retrait de l'élément de commande d'ouverture, du côté opposé à la charnière, ou au contraire faire saillie en avant de l'élément de commande d'ouverture.The cover may be arranged to extend, in the closed position and when the opening control member is at rest, away from the opening control member, the side opposite the hinge, or the opposite protrude forward of the opening control element.

Afin de réduire le risque d'ouverture incontrôlée, l'élément de commande d'ouverture peut être configuré de manière à pouvoir être déplacé d'une course non nulle avant d'agir sur le couvercle. Cela peut permettre au bord du couvercle de faire saillie en avant de l'élément de commande d'ouverture avant que ce dernier n'ait commencé à agir sur le couvercle.In order to reduce the risk of uncontrolled opening, the opening control member may be configured to be movable from a non-zero stroke before acting on the lid. This may allow the edge of the lid to protrude forward of the opening control member before it has begun to act on the lid.

L'orifice de distribution peut être défini par une surface annulaire prolongée intérieurement par au moins une patte élastiquement déformable, agencée pour s'encliqueter sur un picot d'obturation porté par le couvercle. La surface annulaire peut par exemple être prolongée par plusieurs languettes agencées pour s'encliqueter sur le picot d'obturation ailleurs que du côté opposé à la face de l'élément de commande sur laquelle l'utilisateur appuie pour provoquer l'ouverture du couvercle. Cela peut permettre de ne pas trop gêner l'ouverture du couvercle.The dispensing orifice may be defined by an annular surface extended internally by at least one elastically deformable tab, arranged to snap onto a sealing pin carried by the cover. The annular surface may for example be extended by a plurality of tabs arranged to snap onto the sealing pin elsewhere than the opposite side to the face of the control element on which the user presses to cause the lid to open. This can help not to hinder the opening of the lid.

L'invention a encore pour objet un récipient comportant un corps et une capsule de fermeture telle que définie plus haut, fixée sur le corps. Le corps du récipient peut être agencé pour présenter une paroi supérieure épaulée, de manière à guider le déplacement de l'élément de commande d'ouverture.The invention also relates to a container having a body and a closure cap as defined above, fixed on the body. The body of the container may be arranged to have a stepped top wall, so as to guide the movement of the opening control member.

L'invention a encore pour objet, selon un autre de ses aspects, un récipient comportant une capsule de fermeture et un corps sur lequel est fixée la capsule de fermeture, la capsule de fermeture comportant une partie de base fixée sur le corps et un couvercle pouvant pivoter relativement à la partie de base, ainsi qu'un élément de commande d'ouverture mobile relativement à la partie de base pour agir sur le couvercle et provoquer son ouverture. Le corps du récipient est avantageusement agencé pour guider en déplacement l'élément de commande d'ouverture.The invention further relates, in another of its aspects, a container having a closure cap and a body on which is fixed the closure cap, the closure cap having a base portion attached to the body and a lid pivotable relative to the base portion, and an opening control member movable relative to the base portion to act on the lid and cause it to open. The body of the container is advantageously arranged to guide the opening control element in displacement.

Cela peut permettre d'éviter d'avoir à réaliser sur la partie de base un renfoncement servant au guidage de l'élément de commande d'ouverture. Cela peut permettre également de relier l'élément de commande d'ouverture à la partie de base par au moins un élément de liaison déformable, le cas échéant, par exemple un élément de liaison déformable tel que défini plus haut. La partie de base de la capsule peut comporter un plateau et l'élément de commande d'ouverture peut être retenu axialement sur le corps du récipient grâce à ce plateau, avec néanmoins une possibilité de coulissement pour agir sur le couvercle. La réalisation de la capsule de fermeture peut alors s'en trouver facilitée.This may make it possible to avoid having to make on the base part a recess serving to guide the opening control element. It can also be used to connect the opening control element to the base part by at least one deformable connecting element, if necessary, for example a deformable connecting element as defined above. The base portion of the capsule may comprise a plate and the opening control element may be retained axially on the container body by means of this plate, with nevertheless a possibility of sliding to act on the lid. The realization of the closure cap can then be facilitated.

L'invention a encore pour objet, selon un autre de ses aspects, une capsule de fermeture comportant :

  • une partie de base comportant une portion servant à sa fixation sur le col d'un récipient,
  • un élément de commande d'ouverture encliqueté sur la portion de fixation et pouvant coulisser relativement à celle-ci,
  • un couvercle articulé sur la partie de base, l'élément de commande d'ouverture étant agencé pour agir sur le couvercle afin de l'entraîner au moins partiellement vers la position d'ouverture.
Another subject of the invention, according to another of its aspects, is a closure capsule comprising:
  • a base portion having a portion for attachment to the neck of a container,
  • an opening control member snapped onto the fixing portion and slidable therewith,
  • a cover hinged to the base portion, the opening control member being arranged to act on the lid to at least partially drive it to the open position.

L'invention a encore pour objet, selon un autre de ses aspects, un procédé de fabrication d'un récipient, comportant les étapes suivantes :

  • mouler une capsule de fermeture d'une seule pièce, cette capsule de fermeture comportant une partie de base à fixer sur un corps de récipient, un couvercle articulé relativement à la partie de base, et un élément de commande d'ouverture du couvercle comportant une jupe reliée à la partie de base par au moins un élément de liaison, la partie de base comportant un plateau traversé par au moins un orifice de distribution, ce plateau étant moulé avec un espacement non nul entre la jupe et le plateau, par exemple supérieur ou égal à 4 mm, voire à 5 mm,
  • amener la capsule de fermeture sur le corps du récipient, par exemple de manière à positionner la jupe sensiblement dans le prolongement d'une paroi latérale du corps du récipient, et exercer une poussée sur la partie de base de manière à fixer celle-ci sur le corps du récipient, le ou les éléments de liaison se déformant au cours de la fixation de la partie de base sur le corps du récipient et le plateau se rapprochant de la jupe de l'élément de commande d'ouverture.
The invention further relates, in another of its aspects, to a method of manufacturing a container, comprising the following steps:
  • molding a closure cap in one piece, this closure cap having a base portion to be attached to a container body, a cover hinged relative to the base portion, and a cover opening control member having a skirt connected to the base part by at least one connecting element, the base part comprising a plate traversed by at least one dispensing orifice, this plate being molded with a non-zero spacing between the skirt and the plate, for example greater or equal to 4 mm, or even 5 mm,
  • bringing the closure cap onto the body of the container, for example so as to position the skirt substantially in the extension of a side wall of the body of the container, and exert a thrust on the base part so as to fix it on the body of the container, the one or more connecting elements deforming during the fixing of the base part on the body of the container and the plate approaching the skirt of the opening control element.

Le récipient peut être rempli, préalablement ou après montage de la capsule de fermeture, d'un produit fluide ou pulvérulent, par exemple un produit cosmétique, y compris de soin.The container may be filled, before or after mounting the closure cap, a fluid or powder, for example a cosmetic product, including care.

L'invention a encore pour objet, selon un autre de ses aspects, indépendamment ou en combinaison avec ce qui précède, un procédé de fabrication d'un article comportant une première et deuxième pièces assemblées, dans lequel :

  • les deux pièces sont moulées dans un même moule pourvu d'au moins un poussoir d'extraction, la deuxième pièce étant disposée dans le moule relativement à la première de telle sorte que lors du démoulage, un déplacement du poussoir d'extraction s'accompagne d'un déplacement de la deuxième pièce relativement à la première et d'une fixation, par exemple encliquetage, de l'une sur l'autre.
The invention further relates, in another of its aspects, independently or in combination with the above, to a method of manufacturing an article comprising a first and second assembled parts, wherein:
  • the two parts are molded in the same mold provided with at least one extraction pusher, the second part being arranged in the mold relative to the first so that during demolding, a displacement of the extraction pusher is accompanied a displacement of the second piece relative to the first and a fastening, for example latching, of one on the other.

La première pièce est par exemple la partie de base de 1a capsule de fermeture définie ci-dessus et la deuxième pièce l'élément de commande d'ouverture.The first part is for example the base part of the closure cap defined above and the second part the opening control element.

La première pièce peut être moulée dans une première matière et la deuxième pièce dans une deuxième matière, différente de la première, par exemple de couleur différente.The first piece may be molded in a first material and the second piece in a second material, different from the first, for example of different color.

La partie de base peut être moulée d'une seule pièce avec le couvercle.The base part can be molded in one piece with the cover.

Au moins un tiroir peut être prévu dans le moule, délimitant au moins partiellement les cavités servant au moulage des deux pièces. Ce tiroir peut être déplacé pour permettre au poussoir d'extraction d'agir.At least one drawer may be provided in the mold, at least partially delimiting the cavities used for molding the two parts. This drawer can be moved to allow the extraction pusher to act.

L'invention a encore pour objet, indépendamment ou en combinaison avec ce qui précède, une capsule de fermeture comportant :

  • un couvercle muni d'un picot d'obturation,
  • une partie de base sur laquelle le couvercle est articulé, la partie de base comportant un orifice de distribution agencé pour être obturé par le picot d'obturation lorsque le couvercle est fermé, l'orifice de distribution étant défini au moins partiellement par une surface annulaire contre laquelle le picot s'applique de manière étanche en position de fermeture, cette surface étant prolongée inférieurement par une portion d'accrochage agencée pour s'encliqueter sur un relief correspondant du picot d'obturation.
The invention further relates, independently or in combination with the foregoing, to a closure capsule comprising:
  • a lid with a shutter pin,
  • a base portion on which the lid is hinged, the base portion having a dispensing orifice arranged to be closed by the sealing pin when the lid is closed, the dispensing orifice being defined at least partially by an annular surface against which the pin applies sealingly in the closed position, this surface being extended below by a hooking portion arranged to snap on a corresponding relief of the sealing pin.

La surface précitée peut être prolongée par une ou plusieurs pattes élastiquement déformables agencées pour s'encliqueter dans une gorge annulaire formée sur le picot d'obturation.The aforementioned surface may be extended by one or more elastically deformable tabs arranged to snap into an annular groove formed on the closure pin.

Cette surface peut être dépourvue de prolongement coopérant avec le picot d'obturation du côté opposé à la face de l'élément de commande d'ouverture sur laquelle l'utilisateur appuie pour ouvrir le couvercle. Ainsi, l'ouverture du couvercle n'est pas gênée par un accrochage du picot sur la partie de base qui aurait tendance à augmenter alors que l'utilisateur appuierait.This surface may be devoid of extension cooperating with the sealing pin on the opposite side to the face of the opening control element on which the user presses to open the lid. Thus, the opening of the lid is not embarrassed by a pinch hook on the base portion that would tend to increase while the user would support.

L'invention pourra être mieux comprise à la lecture de la description détaillée qui va suivre, d'exemples de mise en oeuvre non limitatifs de celle-ci, et à l'examen du dessin annexé, sur lequel :

Le récipient 1, représenté aux figures 1 et 2, comporte un corps 2 sur lequel est fixée une capsule de fermeture 3.The container 1, shown in FIGS. 1 and 2, comprises a body 2 on which is fixed a closure cap 3.

Dans l'exemple considéré, le récipient 1 présente une forme allongée selon un axe longitudinal X et le corps 2 présente en section transversale une forme oblongue, allongée selon un grand axe Z.In the example considered, the container 1 has an elongate shape along a longitudinal axis X and the body 2 has an oblong shape in cross section, elongated along a major axis Z.

La capsule de fermeture 3, que l'on a représentée isolément sur les figures 3 à 6, comporte une partie de base 5 pourvue d'un orifice de distribution 6, un couvercle 7 articulé sur la partie de base 5 autour d'un axe Y sensiblement parallèle au grand axe Z et un élément de commande d'ouverture 8 mobile relativement à la partie de base dans une direction généralement perpendiculaire à l'axe d'articulation Y.The closure cap 3, which has been shown separately in FIGS. 3 to 6, comprises a base portion 5 provided with a dispensing orifice 6, a cover 7 articulated on the base part 5 about an axis Y substantially parallel to the major axis Z and an opening control member 8 movable relative to the base portion in a direction generally perpendicular to the hinge axis Y.

Le couvercle 7 est relié à la partie de base par une charnière film 10 comportant deux parties disposées de part et d'autre d'une languette 12 formant ressort, parfois encore appelée genouillère, passant par un état de contrainte maximale dans une position intermédiaire entre la position fermée et la position ouverte, de manière à assister le mouvement d'ouverture du couvercle 7 et faire en sorte que ce dernier, une fois ouvert, conserve sa position.The lid 7 is connected to the base portion by a film hinge 10 having two parts disposed on either side of a tongue 12 forming a spring, sometimes called knee, passing through a state of maximum stress in an intermediate position between the closed position and the open position, so as to assist the opening movement of the cover 7 and ensure that the latter, once opened, maintains its position.

Le couvercle 7 comporte un picot 14 d'obturation de l'orifice 6, pourvu d'au moins un relief 15 configuré pour s'encliqueter sur le bord inférieur 16 de l'orifice 6 lorsque le couvercle 7 est complètement fermé.The lid 7 comprises a pin 14 for closing the orifice 6, provided with at least one relief 15 configured to snap onto the lower edge 16 of the orifice 6 when the lid 7 is completely closed.

La partie de base 5 comporte d'une part un plateau 20 allongé selon un grand axe W et sur la face supérieure duquel débouche l'orifice 6 et d'autre part une portion 22, s'étendant sous le plateau 20, servant à la fixation sur un col 24 du récipient, lequel est apparent sur la figure 7.The base portion 5 comprises on the one hand an elongate plate 20 along a major axis W and on the upper face of which opens the orifice 6 and on the other hand a portion 22, extending under the plate 20, used for the fixing on a neck 24 of the container, which is apparent in FIG.

Dans l'exemple considéré, la portion 22 se présente sous la forme d'une jupe de montage tubulaire d'axe K, pourvue inférieurement sur sa face radialement intérieure d'un bourrelet annulaire 23 destiné à s'encliqueter sur un bourrelet correspondant 26 du col 24. La portion 22 comporte en outre dans l'exemple considéré deux encoches 28 agencées pour recevoir des nervures 30 du col 24, de manière à ce que le grand axe W du plateau 20 soit sensiblement parallèle au grand axe Z du corps 2.In the example considered, the portion 22 is in the form of a tubular mounting skirt of axis K, provided inferiorly on its radially inner face with an annular bead 23 intended to snap onto a corresponding bead 26 of the neck 24. The portion 22 further comprises in the example considered two notches 28 arranged to receive ribs 30 of the neck 24, so that the major axis W of the plate 20 is substantially parallel to the major axis Z of the body 2.

Une lèvre annulaire d'étanchéité 33 destinée à s'appliquer sur la surface radialement intérieure du col 24 se raccorde sur la face inférieure du plateau 20.An annular sealing lip 33 intended to be applied on the radially inner surface of the neck 24 is connected to the lower face of the plate 20.

L'élément de commande d'ouverture 8 comporte une jupe tubulaire 40 qui s'étend tout autour du col 24, et qui présente dans l'exemple considéré, en section transversale, une forme sensiblement homothétique de celle du corps 2, comme on peut le voir sur les figures 1 et 2.The opening control element 8 comprises a tubular skirt 40 which extends all around the neck 24, and which has, in the example in question, in cross section, a substantially homothetic shape of that of the body 2, as can be seen in FIG. see it in Figures 1 and 2.

La jupe 40 est prolongée en partie supérieure par un retour 41 dirigé vers l'intérieur. Ce retour 41 est recouvert partiellement par le plateau 20 lorsque la capsule 3 est fixée sur le col du récipient 2, comme on peut le voir sur la figure 2.The skirt 40 is extended in the upper part by a return 41 directed inwards. This return 41 is partially covered by the plate 20 when the capsule 3 is fixed on the neck of the container 2, as can be seen in FIG.

La jupe 40 de l'élément de commande d'ouverture 8 est reliée à la portion 22 de la partie de base 5 par l'intermédiaire dans l'exemple considéré de deux bras 45 élastiquement déformables, présentant chacun sensiblement la forme d'une période de sinusoïde. Les bras 45 rejoignent la jupe 40 et la portion 22 en des emplacements situés sensiblement dans un plan contenant le grand axe W de la capsule 3. Lorsque cette dernière est moulée, les bras 45 s'étendent sensiblement dans le prolongement du retour 41, perpendiculairement à l'axe K de la portion 22. L'écartement d entre le plateau 20 et le retour 41 est alors par exemple de l'ordre de 5 mm, ce qui facilite la réalisation de la capsule par moulage d'une matière thermoplastique, par exemple une polyoléfine.The skirt 40 of the opening control element 8 is connected to the portion 22 of the base portion 5 via the example in the example of two arms 45. elastically deformable, each having substantially the shape of a sinusoidal period. The arms 45 join the skirt 40 and the portion 22 at locations substantially in a plane containing the major axis W of the capsule 3. When the latter is molded, the arms 45 extend substantially in the extension of the return 41, perpendicularly to the axis K of the portion 22. The distance d between the plate 20 and the return 41 is then for example of the order of 5 mm, which facilitates the realization of the capsule by molding a thermoplastic material, for example a polyolefin.

Lors du montage de la capsule sur le corps du récipient, les bras 45 peuvent se déformer obliquement vers le bas pour permettre à la portion 22 de s'encliqueter sur le col 24, comme illustré à la figure 10.When mounting the capsule on the body of the container, the arms 45 can deform obliquely downward to allow the portion 22 to snap on the neck 24, as shown in Figure 10.

L'élément de commande d'ouverture 8 comporte des montants 49 s'étendant sensiblement parallèlement à l'axe K de part et d'autre de la portion 22 et destinés à coopérer avec des surfaces de guidage 50 formées par des épaulements de la paroi supérieure transversale 52 du corps 2, sur laquelle se raccorde inférieurement le col 24. Ces surfaces de guidage 50 sont orientées sensiblement perpendiculairement au grand axe Z du récipient. La coopération des montants 49 et des surfaces 50, par appui des montants 49 sur ces dernières, assure le guidage en translation de la jupe 40 selon une direction perpendiculaire au grand axe W.The opening control element 8 comprises uprights 49 extending substantially parallel to the axis K on either side of the portion 22 and intended to cooperate with guide surfaces 50 formed by shoulders of the wall upper transverse 52 of the body 2, which is connected below the neck 24. These guide surfaces 50 are oriented substantially perpendicular to the major axis Z of the container. The cooperation of the uprights 49 and the surfaces 50, by supporting the uprights 49 on the latter, ensures the translational guidance of the skirt 40 in a direction perpendicular to the major axis W.

Lors du montage de la capsule de fermeture 3 sur le corps du récipient 2, le couvercle 7 étant rabattu sur le plateau 20, la jupe 40 vient tout d'abord en appui contre la paroi transversale supérieure 52 du récipient, à la périphérie de celle-ci, comme on peut le voir sur les figures 8 et 9.When mounting the closure cap 3 on the body of the container 2, the lid 7 being folded down on the plate 20, the skirt 40 comes first against the upper transverse wall 52 of the container, on the periphery of the as can be seen in Figures 8 and 9.

Lorsqu'une poussée est exercée sur le couvercle 7 en direction du corps 2, le plateau 20 se rapproche du retour 41 et la portion 22 se fixe par encliquetage sur le col 24, comme on peut le voir sur les figures 10 et 11. Le jeu final entre le plateau 20 et le retour 41 est de 0,2 à 0,5 mm, par exemple.When thrust is exerted on the cover 7 in the direction of the body 2, the plate 20 approaches the return 41 and the portion 22 is fixed by snapping on the neck 24, as can be seen in Figures 10 and 11. The final clearance between the plate 20 and the return 41 is 0.2 to 0.5 mm, for example.

L'élément de commande d'ouverture 8 comporte, du côté opposé à la surface 100 sur laquelle l'utilisateur appuie pour commander l'ouverture, une patte 60 destinée à agir sur la languette formant ressort 12, afin de pousser cette dernière jusqu'au point de déclenchement amenant le couvercle à s'ouvrir.The opening control element 8 comprises, on the opposite side to the surface 100 on which the user presses to control the opening, a tab 60 intended to act on the spring tongue 12, in order to push the latter up to at the trigger point causing the lid to open.

L'élément de commande d'ouverture 8 est également agencé pour agir sur un relief 63 du couvercle 7 afin de provoquer un début de soulèvement du couvercle et notamment le désengagement du picot d'obturation 14, comme illustré à la figure 12.The opening control element 8 is also arranged to act on a relief 63 of the cover 7 in order to cause the lid to begin to rise and in particular to disengage the closure pin 14, as illustrated in FIG. 12.

Dans l'exemple considéré, le relief 63 se présente sous la forme d'une dent réalisée à proximité du bord du couvercle qui est opposé à la charnière 10.In the example considered, the relief 63 is in the form of a tooth made near the edge of the lid which is opposite the hinge 10.

Le plateau 20 comporte, sur son bord opposé à la charnière 10, une ouverture 66 pour le passage de la dent 63. Le retour 41 comporte une encoche 70 dont le fond 71 peut venir en appui contre une face inclinée de la dent 63, de manière à provoquer le soulèvement du couvercle lors du déplacement de la jupe 40, comme on peut le voir sur la figure 12.The plate 20 comprises, on its edge opposite the hinge 10, an opening 66 for the passage of the tooth 63. The return 41 has a notch 70 whose bottom 71 can bear against an inclined face of the tooth 63, so as to cause the lifting of the lid during the displacement of the skirt 40, as can be seen in FIG. 12.

La patte 60 présente, dans l'exemple illustré, une forme d'équerre et son extrémité libre 72 se situe, lorsque la capsule de fermeture 3 est en place sur le récipient, à un niveau légèrement supérieur à celui de l'axe de rotation Y du couvercle.The tab 60 has, in the example illustrated, a square shape and its free end 72 is located, when the closure cap 3 is in place on the container, at a level slightly greater than that of the axis of rotation Y of the lid.

Lorsque l'utilisateur appuie sur l'organe de commande d'ouverture 8 dans le sens de la flèche O, la patte 60 en forme d'équerre appuie par son extrémité 72 sur la languette formant ressort 12 jusqu'à ce que celle-ci passe par son état de contrainte maximale, la fin du mouvement d'ouverture du couvercle étant assurée par la restitution de l'énergie accumulée dans la languette formant ressort 12.When the user presses the opening control member 8 in the direction of the arrow O, the bracket-shaped tab 60 bears at its end 72 on the spring tab 12 until the latter passes through its state of maximum stress, the end of the opening movement of the cover being ensured by the return of the energy accumulated in the spring tongue 12.

Lors du déplacement de l'organe de commande d'ouverture 8 pour ouvrir le couvercle, les bras 45 se sont déformés élastiquement. Une fois que l'utilisateur cesse d'appuyer sur la jupe 40 et relâche celle-ci, les bras 45 peuvent la ramener sensiblement dans sa position initiale, comme illustré à la figure 14.When moving the opening control member 8 to open the lid, the arms 45 have elastically deformed. Once the user stops pressing the skirt 40 and releases it, the arms 45 can bring it substantially back to its initial position, as illustrated in FIG. 14.

On a représenté aux figures 15 et 16 un récipient 1 comportant une capsule de fermeture 3 et un corps 2 qui se présente sous la forme d'un tube souple. Dans cet exemple, le corps 2 présente en partie supérieure une section transversale sensiblement circulaire et la jupe 40 présente également, en section transversale, une forme sensiblement circulaire.FIGS. 15 and 16 show a container 1 comprising a closure cap 3 and a body 2 which is in the form of a flexible tube. In this example, the body 2 has in the upper part a substantially circular cross section and the skirt 40 also has, in cross section, a substantially circular shape.

On va maintenant décrire en se référant aux figures 17 à 27 une variante de réalisation du récipient.A variant embodiment of the container will now be described with reference to FIGS. 17 to 27.

Cet exemple se distingue de celui des figures 1 à 14 notamment par la manière dont l'élément de commande d'ouverture 8 est relié à la partie de base 5.This example differs from that of FIGS. 1 to 14 in particular by the way in which the opening control element 8 is connected to the base part 5.

Les bras 45 précédemment décrits sont remplacés par des bras 110 qui s'étendent chacun entre deux régions opposées 111 et 112 du bord radialement intérieur du retour 41, comme on peut le voir sur les figures 20 et 22 notamment. Chaque bras 110 présente une portion incurvée 114 adaptée à épouser sensiblement la forme de la portion 22 de la partie de base servant à sa fixation sur le col 24 du récipient, lorsque l'utilisateur n'exerce aucune pression sur l'élément de commande d'ouverture 8. La portion 22 comporte, dans l'exemple considéré, une jupe de montage agencée pour s'encliqueter sur le col 24.The arms 45 previously described are replaced by arms 110 which each extend between two opposite regions 111 and 112 of the radially inner edge of the return 41, as can be seen in Figures 20 and 22 in particular. Each arm 110 has a curved portion 114 adapted to substantially match the shape of the portion 22 of the base portion for its attachment to the neck 24 of the container, when the user does not exert any pressure on the control element. 8. The portion 22 comprises, in the example considered, a mounting skirt arranged to snap on the neck 24.

Les portions incurvées 114 se raccordent au bord 111 par des portions 120 parallèles entre elles et perpendiculaires toutes deux au grand axe W. Les portions incurvées 114 se raccordent au bord 112 par des portions rectilignes 122 qui divergent légèrement en direction du bord 112.The curved portions 114 are connected to the edge 111 by portions 120 parallel to each other and both perpendicular to the major axis W. The curved portions 114 are connected to the edge 112 by rectilinear portions 122 which diverge slightly towards the edge 112.

Lorsque l'élément de commande d'ouverture 8 est en place sur la partie de base 5, les bras 110 sont encliquetés entre le plateau 20 et des reliefs 148 portés par la portion 22, comme on peut le voir sur la figure 23 notamment.When the opening control element 8 is in place on the base portion 5, the arms 110 are snapped between the plate 20 and reliefs 148 carried by the portion 22, as can be seen in Figure 23 in particular.

Lorsque l'utilisateur appuie sur la jupe 40 pour provoquer l'ouverture du couvercle, les bras 110 se déforment élastiquement, comme illustré à la figure 27. Chaque coude 126 formé à la jonction des portions incurvée 114 et rectiligne 122 demeure, au terme du déplacement de la jupe 40, du même côté du demi-plan contenant l'axe de l'orifice de distribution 6 et le grand axe W, de telle sorte que lorsque l'utilisateur relâche l'élément de commande d'ouverture 8, les bras 110 tendent à ramener ce dernier dans sa position initiale, représentée à la figure 26.When the user presses on the skirt 40 to cause the lid to open, the arms 110 deform elastically, as shown in FIG. 27. Each elbow 126 formed at the junction of the curved and rectilinear portions 114 remains, at the end of the displacement of the skirt 40, on the same side of the half-plane containing the axis of the dispensing orifice 6 and the major axis W, so that when the user releases the opening control element 8, the arm 110 tend to bring the latter back to its initial position, represented in FIG.

Le corps 2 du récipient peut comporter un renfoncement 140, comme illustré à la figure 17, et la jupe 40 peut présenter du côté où l'utilisateur appuie une extension 141 épousant la forme de ce renfoncement 140, comme illustré aux figures 18 et 19.The body 2 of the container may comprise a recess 140, as shown in Figure 17, and the skirt 40 may have the side where the user supports an extension 141 conforming to the shape of the recess 140, as shown in Figures 18 and 19.

La capsule de fermeture 3 peut être fabriquée dans un même moule, comme on va maintenant le décrire en se référant aux figures 28 à 39.The closure cap 3 can be manufactured in the same mold, as will now be described with reference to Figures 28 to 39.

Le moule 200 utilisé comporte une première partie 201 et une deuxième partie 202 qui définissent une première cavité 203 pour le moulage de la partie de base et du couvercle et une deuxième cavité 204 qui peut être sans communication avec la cavité 203, pour le moulage de l'élément de commande d'ouverture 8.The mold 200 used has a first portion 201 and a second portion 202 which define a first cavity 203 for molding the base portion and the cover and a second cavity 204 which can be without communication with the cavity 203, for the molding of the opening control element 8.

La matière est injectée dans les cavités 203 et 204, dans l'exemple considéré, par des canaux d'injection respectifs 205 et 206.The material is injected into the cavities 203 and 204, in the example under consideration, by respective injection channels 205 and 206.

La cavité 203 est définie entre d'une part des pièces 210 et 218 appartenant à la deuxième partie 202 du moule, et d'autre part des tiroirs latéraux 211 et 212 et des pièces 213 et 215 appartenant à la première partie 201 du moule.The cavity 203 is defined between on the one hand parts 210 and 218 belonging to the second part 202 of the mold, and secondly side drawers 211 and 212 and parts 213 and 215 belonging to the first part 201 of the mold.

La cavité 204 est définie entre d'une part la pièce 210 et d'autre part la pièce 215, les tiroirs 211 et 212, une pièce 220 et un poussoir d'extraction 219.The cavity 204 is defined between, on the one hand, the part 210 and, on the other hand, the part 215, the drawers 211 and 212, a part 220 and an extraction pusher 219.

Le moule étant fermé, on procède au remplissage des cavités 203 et 204.The mold being closed, the cavities 203 and 204 are filled.

Il peut s'agir d'une même matière thermoplastique avec des couleurs différentes et/ou de matières chimiques différentes.It may be the same thermoplastic material with different colors and / or different chemical materials.

L'injection peut avoir lieu simultanément dans les cavités 204 et 203, comme illustré à la figure 30.The injection can take place simultaneously in the cavities 204 and 203, as illustrated in FIG. 30.

Après l'injection, la deuxième partie du moule 202 est éloignée de la première, comme illustré aux figures 32 et 33. Les tiroirs 211 et 212 peuvent être écartés comme illustré sur la figure 34.After the injection, the second part of the mold 202 is moved away from the first, as illustrated in FIGS. 32 and 33. The drawers 211 and 212 can be spaced apart as illustrated in FIG.

Ensuite, comme illustré aux figures 36 et 37, le poussoir 219 peut être relevé afin d'amener les bras 110 à s'encliqueter derrière les dents 148 de la portion 22 de la partie de base 5Then, as illustrated in Figures 36 and 37, the pusher 219 can be raised to cause the arms 110 to snap behind the teeth 148 of the portion 22 of the base portion 5.

L'extraction complète de la capsule de fermeture peut ensuite avoir lieu en prolongeant la course vers le haut du poussoir 219, comme illustré aux figures 38 et 39.The complete extraction of the closure cap can then take place by extending the upward stroke of the pusher 219, as illustrated in FIGS. 38 and 39.

Quelque soit la manière dont l'élément de commande d'ouverture 8 est relié à la partie de base 5, la jupe 40 de l'élément de commande d'ouverture 8 peut être réalisée, comme illustré à la figure 40, de manière à ce que sa course d'enfoncement s'effectue, avant que la dent 63 ne vienne en appui contre le bord du retour 41, sur une distance M supérieure à la distance m de laquelle la jupe 40 fait éventuellement saillie vers l'avant par rapport au bord libre 170 du couvercle 7.Whatever the manner in which the opening control element 8 is connected to the base part 5, the skirt 40 of the opening control element 8 can be made, as illustrated in FIG. 40, so as to its driving stroke is carried out before the tooth 63 comes to bear against the edge of the return 41, over a distance M greater than the distance m from which the skirt 40 may project forward with respect to at the free edge 170 of the lid 7.

Ainsi, le bord 170 peut s'opposer à un enfoncement accidentel de la jupe 40 lors du transport du récipient par exemple, en venant à l'aplomb de la jupe 40 avant que celle-ci n'appuie par le retour 41 contre la dent 63, comme illustré aux figures 41 et 42.Thus, the edge 170 can oppose accidental depression of the skirt 40 during transport of the container for example, coming directly above the skirt 40 before it bears by the return 41 against the tooth 63, as shown in Figures 41 and 42.

Egalement selon un autre aspect de l'invention, l'orifice de distribution 6 peut être défini par une surface annulaire 180, par exemple cylindrique, prolongée inférieurement par des pattes 181 pouvant comporter des dents 182 destinées à s'encliqueter dans une gorge correspondante 183 du picot d'obturation 14, comme illustré aux figures 42 à 44.Also according to another aspect of the invention, the dispensing orifice 6 may be defined by an annular surface 180, for example cylindrical, extended below by tabs 181 may include teeth 182 for snap into a corresponding groove 183 of the sealing pin 14, as shown in Figures 42 to 44.

La surface 180 peut ne pas être prolongée, du côté de la charnière du couvercle, par une patte 181 pourvue d'une dent 182, de manière à faciliter l'ouverture du couvercle.The surface 180 may not be extended, on the hinge side of the lid, by a tab 181 provided with a tooth 182, so as to facilitate the opening of the lid.

Le picot d'obturation et l'orifice de distribution peuvent être réalisés conformément à l'enseignement de la demande de brevet US 2005/0173366 .The sealing pin and the dispensing orifice may be made in accordance with the teaching of the patent application. US 2005/0173366 .
