Abstract

The locking closure is for a packaging box with sidewalls (1,2) and a small packaging flap (4) on opposing sidewalls. The other sidewalls have folded panel sections (3) with pleated side flaps (5) defining T-shaped lugs (7). The lugs engage apertures (8) in the adjacent sidewalls and expand to their original size after insertion to retain the closure in place.

Description

La présente invention concerne un système de fermeture et de verrouillage des rabats externes d'un emballage en un matériau semi-rigide tel que le carton ou le carton ondulé. L'invention concerne également les emballages en un matériau semi-rigide comportant ce système de verrouillage.The present invention relates to a closure and locking the outer flaps of a packaging made of a semi-rigid material such as cardboard or corrugated cardboard. The invention relates to packaging made of a semi-rigid material containing this Lock system.

De très nombreux emballages en carton ondulé comportent quatre parois latérales articulées entre elles par des refoulages parallèles et disposées perpendiculairement les unes aux autres, et des volets rectangulaires articulés sur ces parois par des refoulages perpendiculaires aux précédents, disposés sensiblement dans un même plan à la base et/ou à la partie supérieure de ces parois. Ces volets sont dénommés rabats dans la technique, car ils sont destinés à être rabattus perpendiculairement aux parois attenantes, pour être ensuite assemblés entre eux pour fermer l'emballage à sa base, où ils constituent le fond de celui-ci, et/ou à sa partie supérieure; après remplissage de l'emballage.A lot of corrugated packaging has four side walls hinged together by parallel ups and downs arranged perpendicular to each other, and shutters rectangular articulated on these walls by upsets perpendicular to the preceding ones, arranged substantially in the same plan at the base and / or at the top of these walls. These shutters are referred to as flaps in the technique because they are intended to be folded perpendicularly to the adjoining walls, to be next assembled together to close the package at its base, where they constitute the bottom of it, and / or at its upper part; after filling the package.

En position de fermeture, deux de ces rabats, de petites dimensions, attenants à deux parois parallèles de l'emballage, sont disposés dans un même plan à l'intérieur de l'emballage, tandis que deux autres rabats, de plus grandes dimensions, attenants aux deux autres parois, sont disposés bord à bord à l'extérieur de l'emballage, où ils recouvrent les petits rabats. Ces rabats externes sont verrouillés en position rabattue par divers moyens connus dans la technique, notamment par collage ou agrafage sur les rabats internes, ou à l'aide de rubans adhésifs recouvrant les bords contigus des rabats externes.In the closed position, two of these flaps, small dimensions, adjacent to two parallel walls of the packaging, are placed in the same plane inside the package, while two other flaps, larger, adjoining both other walls, are placed edge-to-edge on the outside of the package, where they cover the small flaps. These external flaps are locked in position folded by various means known in the art, especially by gluing or stapling on the internal flaps, or using adhesive tapes covering the contiguous edges of the outer flaps.

La présente invention vise à proposer un système de verrouillage en position de ces rabats externes, qui puisse être mis en oeuvre facilement, manuellement ou mécaniquement, sans consommation accrue du matériau semi-rigide utilisé.The present invention aims to propose a locking system in position of these external flaps, which can be implemented easily, manually or mechanically, without consumption increased semi-rigid material used.

A cet effet, l'invention a pour objet un emballage en un matériau semi-rigide du type défini ci-dessus, caractérisé en ce que les rabats internes ont des dimensions telles que seul un rabat externe vient à leur contact en position rabattue, tandis que l'autre rabat externe est non seulement articulé par un refoulage sur une paroi de l'emballage, mais est également attenant suivant ses bords latéraux perpendiculaires à ce refoulage aux deux parois contiguës par l'intermédiaire d'une articulation formant soufflet, chaque articulation comprenant une partie articulée par un refoulage suivant un bord latéral de ce rabat externe et pouvant être amenée dans le même plan que le rabat interne contigu, et une partie articulée par un refoulage suivant la partie supérieure de la paroi contiguë et pouvant être amenée également dans le même plan que le rabat interne contigu, les deux parties du soufflet étant articulées entre elles par un refoulage faisant un angle de 45° avec le bord latéral du rabat externe et avec l'arête supérieure de la paroi contiguë, de manière à pouvoir être repliées l'un contre l'autre et contre la face externe de cette paroi contiguë lorsque ce rabat externe est amené en position rabattue perpendiculairement à la paroi associée, la partie du soufflet articulée sur la paroi contiguë comportant une patte de verrouillage en forme de T, qui, en position repliée du soufflet contre la paroi contiguë, se trouve en regard d'une ouverture de cette paroi, les dimensions de cette ouverture étant telles que la partie de la patte correspondant à la tête du T doive être déformée pour y être introduite, pour reprendre ensuite sa forme initiale par élasticité, pour être ainsi verrouillée en position, en verrouillant également le rabat externe correspondant en position rabattue,For this purpose, the subject of the invention is a package made of a material semi-rigid of the type defined above, characterized in that the flaps internal dimensions have such dimensions that only an outer flap comes to their contact in the folded position, while the other external flap is not only articulated by an upset on a wall of the package, but is also attached along its lateral edges perpendicular to this upset to the two contiguous walls by through a bellows joint, each joint comprising a portion articulated by an upstanding along an edge side of this outer flap and can be brought in the same plane than the contiguous inner flap, and a hinged portion by a push-up following the upper part of the contiguous wall and can be brought also in the same plane as the contiguous inner flap, the two parts of the bellows being hinged together by an upsetting an angle of 45 ° with the side edge of the outer flap and with the edge top of the contiguous wall, so that it can be folded one against the other and against the outer face of this contiguous wall when this outer flap is brought in the folded position perpendicular to the associated wall, the part of the articulated bellows on the contiguous wall having a T-shaped locking tab, which in position folded bellows against the contiguous wall, is next to a opening of this wall, the dimensions of this opening being such that the part of the paw corresponding to the head of the T must be deformed to be introduced, to resume its original form by elasticity, to be so locked in position, locking also the corresponding external flap in folded position,

De préférence, ce rabat externe a des dimensions telles qu'en position rabattue, il vient à recouvrement sur l'autre rabat externe en position rabattue et le maintient ainsi verrouillé dans cette position.Preferably, this external flap has dimensions such that folded position, it comes to recovery on the other external flap in folded position and keeps it locked in this position.

Avantageusement, la patte en forme de T est articulée sur la partie attenante du soufflet par un refoulage, permettant de replier cette patte contre la face interne de la paroi contiguë, après introduction dans l'ouverture de celle-ci, afin d'assurer un meilleur verrouillage de la patte à l'intérieur de l'emballage.Advantageously, the T-shaped tab is articulated on the part adjoining the bellows by an upsetting, to fold this leg against the inner side of the contiguous wall, after introduction into the opening of the latter, to ensure better locking of the leg inside the packaging.

L'ouverture destinée à recevoir la patte de verrouillage peut être une découpe de préhension ménagée de façon usuelle dans la paroi correspondante.The opening for receiving the locking tab can be a gripping cut formed in the usual manner in the wall corresponding.

Un volet escamotable, articulé par un refoulage sur cette paroi, peut être prévu pour obturer l'ouverture dans laquelle est engagée la patte de verrouillage afin d'accroítre la sûreté de ce verrouillage.A retractable flap, articulated by a push-back on this wall, may be provided to close the opening in which is engaged the locking tab to increase the safety of this lock.

D'autres caractéristiques et avantages de l'invention apparaítront dans la description détaillée qui va suivre de formes de mise en oeuvre de l'invention. Dans cette description, on se référera aux dessins schématiques annexés, sur lesquels :

  • La figure 1 est une vue en perspective d'un emballage en carton ondulé ouvert, comportant le système de verrouillage conforme à l'invention ;
  • La figure 2 montre cet emballage en cours de fermeture ;

  • La figure 5 est une vue partielle à plus grande échelle d'une autre ouverture de paroi apte à recevoir une patte de verrouillage de l'emballage.
    • Other features and advantages of the invention will become apparent in the detailed description which follows of embodiments of the invention. In this description, reference will be made to the attached schematic drawings, in which:
  • Figure 1 is a perspective view of an open corrugated cardboard package, comprising the locking system according to the invention;
  • Figure 2 shows this packaging being closed;
  • Figure 3 is a perspective view of the closed package;
  • Figure 4 is a partial view on a larger scale illustrating the introduction of a locking tab of this package in the wall opening for receiving it;
  • Figure 5 is a partial view on a larger scale of another wall opening adapted to receive a locking tab of the package.

    • On se référera d'abord aux figures 1 à 4.Reference is made first to FIGS. 1 to 4.

    Le fond de l'emballage n'a pas été figuré, car il peut être absolument quelconque (fond automatique, semi-automatique, à rabats, etc...).The bottom of the packaging was not figured because it can be absolutely any kind (automatic, semi-automatic flaps, etc ...).

    Cet emballage comprend quatre parois rectangulaires articulées entre elles par des refoulages parallèles, à savoir deux parois longitudinales 1 et deux parois transversales 2 perpendiculaires aux précédentes, les quatre parois étant perpendiculaires au fond et attenantes à des parties de celui-ci.This package includes four articulated rectangular walls between them by parallel upsets, namely two walls longitudinal lines 1 and two transverse walls 2 perpendicular to the preceding, the four walls being perpendicular to the bottom and adjoining parts of it.

    Deux volets 3 rectangulaires sont articulés à la partie supérieure des parois 1 par des refoulages perpendiculaires à ceux par lesquels les parois 1 et 2 sont articulées entre elles.Two rectangular shutters 3 are hinged to the upper part walls 1 by ups and downs perpendicular to those by which the walls 1 and 2 are hinged together.

    De façon analogue, deux volets 4 sont articulés par des refoulages à la partie supérieure des parois 2.Similarly, two flaps 4 are articulated by upsets at the top of the walls 2.

    Les volets 3 et 4 peuvent ainsi être rabattus perpendiculairement aux parois attenantes pour fermer l'emballage et, dans cette position, les volets 3 sont au-dessus des volets 4. C'est pourquoi les volets 3 sont appelés rabats externes et les volets 4 rabats internes.The shutters 3 and 4 can thus be folded perpendicularly adjacent walls to close the packaging and, in that position, the shutters 3 are above the shutters 4. This is why the shutters 3 are called external flaps and flaps 4 internal flaps.

    Les rabats internes 4 sont habituellement articulés sur les parois 2 suivant toute la longueur de ces parois, mais ici, pour les raisons qui seront exposées ci-après, ils ne s'étendent que suivant environ une partie de cette longueur et seul l'un des rabats externes 3 vient à leur contact en position rabattue. The internal flaps 4 are usually articulated on the walls 2 following the entire length of these walls, but here for the reasons that will be explained below, they only extend part of this length and only one of the outer flaps 3 comes to them contact in the folded position.

    En effet, conformément à la présente l'invention, l'autre rabat 3 est relié à chaque paroi 2 contiguë par une articulation formant soufflet, qui comprend une première partie 5, articulée par un refoulage suivant un bord latéral du rabat 3, et une seconde partie 6, articulée sur la partie supérieure de la paroi 2 contiguë par un refoulage disposé dans le prolongement de celui par lequel le rabat interne 4 contigu est articulé sur la même paroi 2. Les parties 5 et 6 sont articulées entre elles par un refoulage formant un angle de 45° avec ceux par lesquels ces parties 5 et 6 sont articulées sur le rabat 3 et sur la paroi 2. Il est ainsi possible de replier les parties 5 et 6 l'une contre l'autre et contre la face externe de la paroi 2, tout en amenant le rabat externe 3 en position de fermeture, rabattu perpendiculairement à la paroi 1.Indeed, according to the present invention, the other flap 3 is connected to each wall 2 contiguous by a bellows joint, which comprises a first part 5, articulated by a subsequent upsetting a side edge of the flap 3, and a second part 6 articulated on the upper part of the wall 2 contiguous by a push-back arranged in the extension of the one by which the contiguous internal flap 4 is articulated on the same wall 2. Parts 5 and 6 are articulated between they by an upsetting forming an angle of 45 ° with those by which these parts 5 and 6 are articulated on the flap 3 and on the wall 2. It is thus possible to fold the parts 5 and 6 against each other and against the outer face of the wall 2, while bringing the outer flap 3 into closing position, folded perpendicularly to the wall 1.

    On peut donc considérer que les parties 5 et 6 constituent des parties découpées dans les volets internes habituels qui s'étendent suivant toute la partie supérieure des parois 2, et que la réalisation du soufflet ne consomme ainsi pas plus de carton ondulé que les volets internes de la technique.Parts 5 and 6 can therefore be considered as cut-outs in the usual internal flaps that extend along the upper part of the walls 2, and that the realization of the bellows do not consume more corrugated cardboard than shutters internal techniques.

    Une patte 7 en forme de T est découpée dans la partie 5 de l'articulation en soufflet, en une position telle que, lorsque le rabat 3 est en position rabattue, avec le soufflet replié à l'extérieur de la paroi 2, cette patte 7 se trouve en regard d'une ouverture 8 ménagée en position correspondante dans cette paroi 2.A tab 7 T-shaped is cut in part 5 of the bellows joint, in a position such that when the flap 3 is in the folded position, with the bellows folded outside the wall 2, this tab 7 is opposite an opening 8 arranged in position corresponding in this wall 2.

    Comme on le voit sur la figure 4, les dimensions de l'ouverture 8 sont telles que les extrémités de la barre du T de la patte 7 doivent être repliées pour pouvoir être introduites dans l'ouverture, ces extrémités revenant ensuite à leur position initiale, du fait de l'élasticité du carton, et verrouillant ainsi la patte 7 à l'intérieur de l'emballage.As seen in Figure 4, the dimensions of the opening 8 are such that the ends of the T bar of the paw 7 must be folded to be introduced into the opening, these ends then returning to their original position, because of the elasticity of the cardboard, and thus locking the tab 7 inside the package.

    Le rabat 3 attenant au soufflet est ainsi verrouillé en position rabattue et, comme ses dimensions sont telles que, dans cette position, il recouvre la partie contiguë du second rabat 3, également en position rabattue, celui-ci est aussi verrouillé dans cette portion.The flap 3 adjoining the bellows is thus locked in position folded and, as its dimensions are such that, in that position, it covers the contiguous portion of the second flap 3, also in position folded, it is also locked in this portion.

    Comme représenté sur la figure 4, des refoulages peuvent être prévus sur la barre du T des pattes 7 pour favoriser leur introduction dans les ouvertures 8 associées.As shown in FIG. 4, upsets can be provided on the bar T of the legs 7 to promote their introduction in the associated openings 8.

    Avantageusement, les pattes 7 sont elles-mêmes articulées sur la partie 5 du soufflet par un refoulage facilitant leur introduction dans les ouvertures 8 et permettant de les amener au contact de la face interne de la paroi 2 correspondante, pour améliorer la sécurité du verrouillage.Advantageously, the legs 7 are themselves articulated on the part 5 of the bellows by a push-up facilitating their introduction in the openings 8 and to bring them into contact with the inner face of the corresponding wall 2, to improve the security of the lock.

    Les opérations de mise en place des pattes 7 dans leur logement sont à l'évidence d'une grande simplicité et peuvent être effectuées manuellement ou mécaniquement.The operations of placing legs 7 in their housing are obviously very simple and can be done manually or mechanically.

    Les ouvertures 8 peuvent être de simples découpes de préhension, comme il en existe déjà sur les emballages.The openings 8 may be simple gripping cutouts, as it already exists on packaging.

    Comme représenté sur la figure 5, chaque découpe 8 peut être obturée par un volet 9 de forme complémentaire, articulé par un refoulage suivant un bord de la découpe et apte à s'escamoter ainsi vers l'intérieur de l'emballage pour laisser passer la patte de verrouillage 7, pour revenir ensuite sensiblement à sa position initiale et éviter toute sortie accidentelle de cette patte à l'extérieur de l'emballage.As shown in FIG. 5, each cutout 8 can be closed by a shutter 9 of complementary shape, articulated by a pushing along an edge of the cutout and able to retract to inside the package to let the locking lug 7, then return substantially to its original position and avoid any accidental release of this tab on the outside of the package.
