Description

La présente invention est relative à une boite hermétique à couvercle permettant le rebouchage.The present invention relates to an airtight box with a cover allowing the filling.

Pour le conditionnement de produits tels que peintures, colles, vernis, mastics, cires etc..., on utilise habituellement des boites cylindriques à base ronde, en tôle d'acier revêtue ou non, constituées de quatre éléments :

  • - un fond assujetti au corps cylindrique de la boite par une opération mécanique de double sertissage,
  • - un corps de boite comportant, sur une de ses génératrices, une agrafe étanchée par un ciment ou colle appropriés,
  • - une collerette fixée au corps par double sertissage. Cet élément comporte une ouverture de grande dimension,
  • - un couvercle prévu pour obturer l'ouverture de la collerette.
For the packaging of products such as paints, glues, varnishes, sealants, waxes, etc., cylindrical boxes are usually used with a round base, made of coated or uncoated sheet steel, made up of four elements:
  • - a bottom secured to the cylindrical body of the box by a mechanical double crimping operation,
  • - a box body comprising, on one of its generators, a staple sealed with a suitable cement or glue,
  • - a collar fixed to the body by double crimping. This element has a large opening,
  • - a cover provided to close the opening of the collar.

L'assemblage du couvercle et de la collerette s'effectue par friction. Les deux derniers éléments cités assurent les fonctions de bouchage lors du transport et de rebouchage après prélèvement d'une partie du contenu par l'utilisateur.The assembly of the cover and the collar is effected by friction. The last two elements mentioned provide the closure functions during transport and the filling after removal of part of the content by the user.

La fabrication d'une telle boite comporte un nombre important d'opérations de sertissage, agrafage, roulage, etc....En outre, l'obtention de la collerette, en forme d'anneau, est coûteuse car une très faible partie de la surface du flan initial est utilisée, le reste devant être recyclé.The manufacture of such a box includes a large number of crimping operations, stapling, rolling, etc. In addition, obtaining the ring-shaped flange is costly because a very small part of the surface of the initial blank is used, the rest to be recycled.

Le but de la présente invention est de fournir une boite dont la fabrication soit simplifiée, tout en assurant les mêmes performances de solidité et d'herméticité que les boites classiques.The purpose of the present invention is to provide a box whose manufacture is simplified, while ensuring the same strength and hermeticity performance as conventional boxes.

La présente invention fournit donc une boite hermétique à couvercle permettant le rebouchage, constituée d'un corps qui comprend un fond circulaire et une paroi cylindrique et qui présente à l'extrémité opposée au fond une ouverture circulaire occupant la majeure partie de sa section et dont le bord est constitué par un roulé, et d'un couvercle susceptible d'être mis en place de façon hermétique par simple pression dans le sens de l'axe du corps, qui présente la particularité que le roulé des bords de l'ouverture est formé sur la paroi cylindrique du corps de boite.The present invention therefore provides a hermetic box with a cover allowing the filling, consisting of a body which comprises a circular bottom and a cylindrical wall and which has at the end opposite the bottom a circular opening occupying most of its section and whose the edge consists of a roll, and of a cover capable of being hermetically placed by simple pressure in the direction of the axis of the body, which has the particularity that the roll of the edges of the opening is formed on the cylindrical wall of the box body.

Comme on le voit, la collerette de l'art antérieur n'existe plus dans la boite selon l'invention, laquelle ne comporte donc plus que trois pièces : fond, corps de boite et couvercle, ou même deux seulement si le corps de boite est obtenu par emboutissage et d'une seule pièce avec le fond.As can be seen, the collar of the prior art no longer exists in the box according to the invention, which therefore comprises only three parts: bottom, box body and cover, or even only two if the box body is obtained by stamping and in one piece with the bottom.

On notera que la suppression de la collerette n'a été rendue possible que par l'apparition de techniques modernes pour former le corps de boite : emboutissage, soudure électrique ou par laser, collage, brasage. En effet, la technique classique de l'agrafage ne permettrait pas d'obtenir une étanchéité suffisante au niveau du contact avec le couvercle.It will be noted that the removal of the flange has only been made possible by the appearance of modern techniques for forming the body of the box: stamping, electric or laser welding, bonding, brazing. In fact, the conventional stapling technique would not make it possible to obtain a sufficient seal at the level of contact with the cover.

La présente invention sera décrite plus en détail en s'aidant des figures parmi lesquelles :

  • Fig. 1 est une coupe partielle d'une boite de l'art antérieur et de son couvercle ;
  • Fig. 2 est une coupe partielle d'une boite selon l'invention, et de son couvercle ;
  • Fig. 3 est une vue analogue à celle de la figure 2 et relative à une variante.
The present invention will be described in more detail with the aid of the figures among which:
  • Fig. 1 is a partial section of a box of the prior art and its cover;
  • Fig. 2 is a partial section of a box according to the invention, and of its cover;
  • Fig. 3 is a view similar to that of FIG. 2 and relating to a variant.

La figure 1 montre, en coupe partielle par un plan axial, la partie supérieure de la boite et le bord du couvercle dans une réalisation selon l'art antérieur. Pour faciliter la démonstration, les dimensions n'ont pas été respectées et les sertissages ont été représentés en disposition non écrasée.Figure 1 shows, in partial section through an axial plane, the upper part of the box and the edge of the cover in an embodiment according to the prior art. To facilitate the demonstration, the dimensions were not respected and the crimps were shown in an uncrushed arrangement.

Le flanc cylindrique 1 du corps de boite est relié par un double sertissage 2 à la collerette 3. Celle-ci comporte, en partant de l'extérieur, un bord 4 engagé dans le double sertissage 2 et venant recouvrir l'extrémité du flanc 1, un voile de souplesse 5, de forme générale approximativement tronconique, convergeant vers l'intérieur de la boite, une partie cylindrique 6, se dirigeant vers l'extérieur de la boite à partir du voile 5 c'est-à-dire vers le haut en position normale, et terminée par un roulé externe 7.The cylindrical flank 1 of the box body is connected by a double crimp 2 to the flange 3. The latter comprises, starting from the outside, an edge 4 engaged in the double crimp 2 and coming to cover the end of the flank 1 , a flexible veil 5, of roughly frustoconical general shape, converging towards the inside of the box, a cylindrical part 6, going towards the outside of the box from the veil 5, that is to say towards the high in normal position, and finished with an external roll 7.

Le couvercle8 comporte, à partir de l'extérieur, un bord roulé 9, une partie cylindrique 10 dirigée vers le bas en position normale, et de diamètre extérieur calculé pour pénétrer avec frottement dans la partie cylindrique 6 de la collerette, et une partie de raccordement 11 au voile central 12 situé à un niveau intermédiaire entre le haut du roulé 9 et le bas de la partie 10.The cover 8 comprises, from the outside, a rolled edge 9, a cylindrical part 10 directed downwards in the normal position, and of external diameter calculated to penetrate with friction into the cylindrical part 6 of the flange, and a part of connection 11 to the central veil 12 located at an intermediate level between the top of the roll 9 and the bottom of the part 10.

Pour fermer la boite, on procède par poussée axiale sur le couvercle. Cette poussée tend à déplacer vers le bas la partie cylindrique 6 de la collerette et le voile 5. Le déplacement de celle-ci tend à augmenter le diamètre de cette même partie cylindrique 6 et à faciliter l'entrée du couvercle. En même temps, la partie de raccordement 11 du couvercle se déforme et tend à donner à la partie cylindrique 10 une forme conique qui facilite elle aussi l'introduction du couvercle.To close the box, proceed by axial thrust on the cover. This thrust tends to move down the cylindrical part 6 of the collar and the web 5. The displacement of the latter tends to increase the diameter of this same cylindrical part 6 and to facilitate the entry of the cover. At the same time, the connection part 11 of the cover deforms and tends to give the cylindrical part 10 a conical shape which also facilitates the introduction of the lid.

Une force dirigée en sens inverse produit un phénomène d'arc-boutement du voile 5 et de la partie de raccordement 11, qui s'oppose à une ouverture intempestive, et la boite ne peut être ouverte qu'en insérant un outil entre le roulé 7 et le roulé 9.A force directed in the opposite direction produces a phenomenon of bracing of the veil 5 and of the connection part 11, which opposes an untimely opening, and the box can only be opened by inserting a tool between the roll 7 and the roll 9.

La figure 2 est relative à un exemple non limitatif de boite selon l'invention, et représente la même partie de boite que la figure 1, les mêmes éléments comportant les mêmes repères.Figure 2 relates to a non-limiting example of a box according to the invention, and shows the same part of the box as Figure 1, the same elements having the same references.

Le flanc cylindrique 1 comporte un brasage annulaire 13,dirigé vers l'extérieur et dont la face supérieure 14 est plane. Au-dessus de ce bossage, le flanc 1 comporte une partie cylindrique 15, suivie d'un roulé 16, tourné vers l'intérieur.The cylindrical sidewall 1 has an annular brazing 13, directed outwards and the upper face 14 of which is planar. Above this boss, the sidewall 1 has a cylindrical part 15, followed by a roll 16, facing inward.

Le couvercle 8 présente un bord roulé 17, suivi d'une partie cylindrique externe 18, dirigée, à partir du roulé 17, vers l'extérieur de la boite, c'est-à-dire vers le haut en position normale. Cette partie cylindrique se raccorde à une autre partie cylindrique 19, dite partie cylindrique interne, dirigée en sens inverse, par l'intermédiaire d'une partie de raccordement 20, de forme torique calculée pour que l'espace annulaire entre les deux parties cylindriques 18 et 19 ait une largeur et un diamètre tels que le roulé 16 du corps de boite y pénètre avec frottement.The cover 8 has a rolled edge 17, followed by an external cylindrical part 18, directed, from the roll 17, towards the outside of the box, that is to say upwards in the normal position. This cylindrical part is connected to another cylindrical part 19, called internal cylindrical part, directed in opposite direction, by means of a connection part 20, of toroidal shape calculated so that the annular space between the two cylindrical parts 18 and 19 has a width and a diameter such that the roll 16 of the box body penetrates there with friction.

La partie cylindrique interne 19 se raccorde directement au voile central 12 lequel comporte un gradin 21 pour augmenter sa souplesse.The internal cylindrical part 19 is connected directly to the central web 12 which has a step 21 to increase its flexibility.

La hauteur de la partie cylindrique externe 18 est inférieure à celle de la partie cylindrique 15 du flanc 1 située au-dessus du bossage 13, et la hauteur de la partie cylindrique interne 19 est supérieure au rayon du roulé 16. Suivant une modalité facultative, la partie de raccordement 20 est garnie intérieurement d'une couche de matière d'étanchéité 22. Il est clair que, dans ce cas, les hauteurs des parties cylindriques du couvercle doivent être calculées pour que cette partie d'étanchéité vienne en contact hermétique avec le haut du roulé 16.The height of the external cylindrical part 18 is less than that of the cylindrical part 15 of the sidewall 1 situated above the boss 13, and the height of the internal cylindrical part 19 is greater than the radius of the roll 16. According to an optional method, the connection part 20 is internally lined with a layer of sealing material 22. It is clear that, in this case, the heights of the cylindrical parts of the cover must be calculated so that this sealing part comes into hermetic contact with top of roll 16.

Pour fermer la boite, on procède,,comme pour les boites classiques, par poussée axiale vers le bas sur le couvercle. Sous l'action de cette force, le roulé 16 tend à se refermer sur lui-même en diminuant son rayon, cependant que les parties cylindriques 18 et 19 du couvercle s'écartent grâce à la souplesse du voile central 12 et du roulé 17. Une fois que le roulé 16 se trouve enfoncé dans l'espace entre les parties cylindriques 18 et 19 d'une profondeur suffisante, la partie 18 vient en contact avec la partie cylindrique 15 du flanc, cependant que la partie 19 se rapproche légèrement de la partie 18 en passant au-dessous du roulé 16. Une ouverture intempestive est empêchée par l'existence de deux surfaces de frottement correspondant aux parties cylindriques 18 et 19, et l'ouverture volontaire est obtenue par insertion d'un outil entre la face plane 14 du bossage 13 et le roulé 17.To close the box, we proceed ,, as for conventional boxes, by axial pushing down on the cover. Under the action of this force, the roll 16 tends to close on itself by reducing its radius, while the cylindrical parts 18 and 19 of the cover move apart thanks to the flexibility of the central web 12 and the roll 17. Once the roll 1 6 is pressed into the space between the cylindrical parts 18 and 19 of a sufficient depth, the part 18 comes into contact with the cylindrical part 15 of the sidewall, while the part 19 approaches slightly part 18 passing below the roll 16. An untimely opening is prevented by the existence of two friction surfaces corresponding to the cylindrical parts 18 and 19, and the voluntary opening is obtained by inserting a tool between the flat face 14 of the boss 13 and the roll 17.

Comme on le voit, les moyens d'obtenir la fermeture sont très différents dans leur principe de ceux de la boite qui fait l'objet de la figure 1, car il n'est pas fait appel, en particulier à des phénomènes d'arc-boutement, mais à des phénomènes d'agrafage par pincement.As can be seen, the means of obtaining closure are very different in principle from those of the box which is the subject of FIG. 1, since no use is made of arcing phenomena -butt, but to phenomena of stapling by pinching.

Sur la figure 3 on a représenté une coupe analogue, à une échelle plus réduite, d'une autre boite selon l'invention. On a groupé dans cet exemple un certain nombre de variantes qui ne se retrouvent pas nécessairement toutes ensemble sur une même boite.In Figure 3 there is shown a similar section, on a smaller scale, of another box according to the invention. In this example, we have grouped a number of variants which are not necessarily all found together on the same box.

Le bossage 13 a une section de forme différente de celle, triangulaire,de la figure 2.The boss 13 has a section of shape different from that, triangular, of FIG. 2.

Le rôle de ce bossage est en effet, d'une part de fournir par sa face supérieure plane 14 une surface d'appui pour un outil d'ouverture, et d'autre part, en coopération soit avec la surépaisseur de sertissage du fond soit avec un bossage analogue situé en partie inférieure du corps de boite, de protéger la partie cylindrique 1 de ce dernier contre les frottements ou autres qui pourraient dégrader les inscriptions ou repères qu'il supporte.The role of this boss is in fact, on the one hand to provide, by its planar upper face 14, a bearing surface for an opening tool, and on the other hand, in cooperation with either the bottom crimping thickness or with a similar boss located in the lower part of the box body, to protect the cylindrical part 1 of the latter against friction or the like which could degrade the inscriptions or marks which it supports.

Sur la figure 3, le roulé 16 est représenté tourné vers l'extérieur, son bord externe venant au droit de la partie cylindrique 15 du flanc. Une telle réalisation est un peu plus compliquée, mais elle empêche toute pénétration des matières contenues dans la boite jusqu'à l'intérieur du roulé, ce qui peut être important s'il s'agit de matières corrosives.In FIG. 3, the roll 16 is shown facing outwards, its external edge coming in line with the cylindrical part 15 of the sidewall. Such an embodiment is a little more complicated, but it prevents any penetration of the materials contained in the box up to the inside of the roll, which can be important if they are corrosive materials.

On observera aussi que, sur la figure 3, la partie cylindrique interne 19 du couvercle est reliée au voile central 12 du couvercle par un jonc de verrouillage qui avance en direction de la partie cylindrique externe 18 et qui est constitué de deux parties tronconiques de sens opposés 23 et 24. La pente (ou angle au sommet) de la partie tronconique inférieure 23 est calculée pour que la force nécessaire pour la fermeture reste dans les limites désirées, alors que celle de la partie supérieure 24 conditionne la force nécessaire à l'ouverture de la boite.It will also be observed that, in FIG. 3, the internal cylindrical part 19 of the cover is connected to the central veil 12 of the cover by a locking ring which advances towards the external cylindrical part 18 and which consists of two frustoconical parts of direction opposites 23 and 24. The slope (or angle at the top) of the lower frustoconical part 23 is calculated so that the force necessary for the closure remains within the desired limits, while that of the upper part 24 conditions the force necessary for the opening of the box.
