The invention applies in particular to the reclosing of easily-opened drink cans. <IMAGE>

Description

La présente invention concerne un dispositif de rebouchage d'un récipient à ouverture définitive, tel que, notamment, les boîtes à boisson ou analogues, selon le préambule de la première revendication.The present invention relates to a device for filling a container with a definitive opening, such as, in particular, beverage cans or the like, according to the preamble of the first claim.

On connaît déjà les surcouvercles normalement agencés sur le dessus de certaines boîtes de conserves alimentaires ou de produits pharmaceutiques que l'on veut reboucher après une première ouverture de leur couvercle principal. Cette pratique du surbouchage, qui ne s'est pour l'instant pas généralisée à tous les emballages à ouverture définitive pour des raisons de coût évidentes, procure cependant des avantages incontestables sur le plan de la sécurité et permet d'allonger notablement la durée de conservation des produits altérables ou des denrées périssables contenus dans les emballages. En particulier, il est relativement fréquent que des accidents parfois graves se produisent suite à l'ingestion, par le consommateur, d'un objet ou d'un insecte qui s'est introduit, d'une manière fortuite, par l'ouverture d'une boîte à boisson ; à cet égard, l'opacité du récipient, généralement métallique, empêche le consommateur de s'apercevoir de la présence de l'objet ou de l'insecte en question. Etant donné que l'ouverture de ces boîtes, obtenue par arrachage d'un obturateur frangible, n'est actuellement pas conçue pour être refermée, rien, à ce jour, n'est proposé au consommateur pour s'assurer de l'intégrité du contenu de la boîte qu'il va absorber.We already know the overlaps normally arranged on top of certain cans of canned food or pharmaceutical products that we want to recap after a first opening of their main cover. This practice of overcapping, which has not yet been generalized to all definitive opening packaging for obvious cost reasons, nevertheless provides incontestable advantages in terms of safety and makes it possible to lengthen the duration of conservation of spoilage products or perishable foodstuffs contained in packaging. In particular, it is relatively frequent that sometimes serious accidents occur following the ingestion, by the consumer, of an object or an insect which is introduced, by chance, by the opening of 'a drink can; in this respect, the opacity of the container, generally metallic, prevents the consumer from noticing the presence of the object or insect in question. Since the opening of these boxes, obtained by tearing off a frangible shutter, is currently not designed to be closed, nothing, to date, is offered to the consumer to ensure the integrity of the contents of the box it will absorb.

A cet effet, on connaît quelques solutions au problème qui vient d'être posé ; par exemple le brevet US-A-4 008 823 au nom de TARRO correspondant d'ailleurs au préambule de la première revendication, propose un dispositif de fermeture composé pour l'essentiel d'un secteur métallique ou plastique venant recouvrir l'orifice du récipient par pression, en encastrant une surépaisseur dans ledit orifice ; le verrouillage du dispositif de fermeture, en position fermé ou ouvert, étant obtenu par emboîtement et désemboîtement successif d'une goupille sur le rebord périphérique du couvercle (cf figures 1 à 10). On comprend bien que les manipulations d'un tel dispositif sont compliquées ; en effet, pour boire il convient d'abord de déverrouiller la goupille, de soulever ensuite la languette et enfin de la faire pivoter ; naturellement pour refermer il faut procéder à l'inverse.To this end, we know some solutions to the problem which has just been raised; for example patent US-A-4 008 823 in the name of TARRO corresponding moreover to the preamble of the first claim, proposes a closure device composed essentially of a metallic or plastic sector covering the orifice of the container by pressure, by embedding an additional thickness in said orifice; the locking of the closing device, in the closed or open position, being obtained by successive interlocking and unthreading of a pin on the peripheral edge of the cover (see Figures 1 to 10). We understand that the manipulations of such a device are complicated; indeed, to drink it is first necessary to unlock the pin, then lift the tongue and finally rotate it; Naturally, to close you have to do the opposite.

En outre, ce dispositif doit être nécessairement intégré à la fabrication du récipient, ce qui renchérit considérablement ledit récipient et surtout constitue un obstacle à l'empilage et donc au transport en grande quantité.In addition, this device must necessarily be integrated into the manufacture of the container, which considerably increases said container and above all constitutes an obstacle to stacking and therefore to transport in large quantities.

Dans un autre exemple, proposé par GRAU dans son modèle d'utilité n° DE-U-8 911 286, on trouve une proposition de fermeture par un élément, ici amovible, venant se ficher sur la languette de déchirage de l'opercule frangible ; dans cette solution, on ne peut dégager l'ouverture de l'élément de fermeture qu'en tirant l'ensemble vers le haut, puis en opérant une rotation autour du rivet central. De même, l'occultation de l'orifice s'opère en amenant l'élément au-dessus de l'orifice, puis en exerçant une pression vers le bas pour le verrouiller ; l'élasticité de la seule languette métallique ne suffisant pas à maintenir le dispositif plaqué contre l'orifice. Ceci détériore vite la section métallique reliant la languette au rivet central, qui se rompt par cisaillement dès la deuxième ou troisième manipulation ; en outre, il est peu confortable pour l'utilisateur de devoir lever et tourner la fermeture de la boîte tout en la tenant d'une seule main.In another example, proposed by GRAU in its utility model n ° DE-U-8 911 286, there is a proposal for closure by an element, here removable, coming to fit on the tear-off tab of the frangible cover. ; in this solution, the opening of the closure element can only be released by pulling the assembly upwards, then by rotating around the central rivet. Likewise, the occlusion of the orifice takes place by bringing the element above the orifice, then by exerting a pressure downwards to lock it; the elasticity of the single metal tab is not sufficient to keep the device pressed against the orifice. This quickly deteriorates the metal section connecting the tongue to the central rivet, which breaks by shearing from the second or third manipulation; in addition, it is uncomfortable for the user to have to lift and turn the closure of the box while holding it with one hand.

La présente invention vise à remédier à ces inconvénients en proposant un dispositif de rebouchage d'un récipient comprenant un corps, un fond et un couvercle sur lequel peut être pratiquée une ouverture de dimension inférieure à la dimension dudit couvercle au moyen d'un obturateur frangible connu en soi, pouvant être repoussé à l'intérieur de la boîte par l'effet de levier d'une languette de tirage maintenue au centre et au-dessus dudit couvercle par un rivet caractérisé en ce que, ledit dispositif étant constitué par un étui monté de manière amovible sur ou autour de ladite languette de tirage, avant ou après l'ouverture de la boîte, pour constituer une patte mobile pivotante autour dudit rivet, sur la partie supérieure du couvercle, d'une part ledit étui vient se clipper sur ladite languette de tirage, et d'autre part les bords périphériques extérieurs dudit étui sont conformés pour venir se clipper autour de l'ourlet périphérique de sertissage du couvercle sur le corps du récipient, ourlet servant de rail extérieur lors des déplacements circulaires de l'étui.The present invention aims to remedy these drawbacks by proposing a device for recapping a container comprising a body, a bottom and a cover on which an opening of dimension less than the dimension of said cover can be made by means of a frangible obturator. known per se, which can be pushed back inside the box by the leverage of a pull tab held in the center and above said cover by a rivet characterized in that, said device being constituted by a case removably mounted on or around said pull tab, before or after the opening of the box, to constitute a movable tab pivoting around said rivet, on the upper part of the cover, on the one hand said case is clipped onto said pull tab, and on the other hand the outer peripheral edges of said case are shaped to clip around the peripheral hem of crimping the lid on the body of the container, hem serving as external rail during circular movements of the case.

Selon l'invention, le moyen d'obturation est donc pourvu de moyens de fixation amovible sur les bords du couvercle, de sorte qu'il pourra être rapporté sur le récipient avant ou après son ouverture, ce qui permet :

  • soit de le rajouter sur chaque récipient, postérieurement et indépendamment des filières industrielles de conditionnement des récipients eux-mêmes, ledit moyen de fixation étant alors un bouchon à usage unique,
  • soit d'en faire un bouchon réutilisable par le consommateur averti, ledit moyen d'obturation devant alors pouvoir s'adapter aux géométries des différents récipients du commerce.
According to the invention, the closure means is therefore provided with removable fixing means on the edges of the cover, so that it can be attached to the container before or after its opening, which allows:
  • either to add it to each container, later and independently of the industrial packaging channels for the containers themselves, said fixing means then being a disposable cap,
  • or to make it a reusable stopper for the informed consumer, said sealing means then having to be able to adapt to the geometries of the various commercial containers.

D'un autre côté, on a ainsi mis en évidence que les moyens de fixation du moyen d'obturation de l'ouverture du récipient pouvaient avantageusement être des moyens de fixation par clippage, ce qui permet, d'une part, d'assurer un bon placage dudit moyen d'obturation contre les bords de ladite ouverture et, d'autre part, de faciliter l'adaptation dudit moyen d'obturation aux bords de la plupart des couvercles du commerce, ces derniers étant généralement sertis sur le corps des récipients qu'ils obturent.On the other hand, it has thus been demonstrated that the means for fixing the means for closing the opening of the container could advantageously be means for fixing by clipping, which makes it possible, on the one hand, to ensure good plating of said closure means against the edges of said opening and, on the other hand, of facilitating the adaptation of said closure means to the edges of most commercial covers, the latter being generally crimped onto the body of the containers they seal.

D'autres caractéristiques et avantages de la présente invention ressortiront mieux de la description qui va suivre d'un mode de réalisation d'un moyen de rebouchage d'un récipient du type d'une boîte à boisson pourvue d'un couvercle à ouverture facile et définitive, ce mode de réalisation étant donné à titre d'exemple non limitatif de l'invention, en référence au dessin annexé sur lequel :

  • la figure 1 est une vue en perspective éclatée d'un dispositif de rebouchage, conforme à l'invention, monté sur la languette de tirage de l'obturateur frangible du couvercle serti d'une boîte à boisson,
  • la figure 2 est une vue en coupe verticale grossie du dispositif de rebouchage, représenté sur la figure 1, une fois monté sur la partie supérieure du couvercle.
Other characteristics and advantages of the present invention will emerge more clearly from the description which follows of an embodiment of a means of filling a container of the type of a beverage can provided with an easy-opening lid. and definitive, this embodiment given by way of example not limitation of the invention, with reference to the attached drawing in which:
  • FIG. 1 is an exploded perspective view of a filling device, in accordance with the invention, mounted on the pull tab of the frangible shutter of the cover set with a beverage can,
  • Figure 2 is an enlarged vertical sectional view of the filling device, shown in Figure 1, once mounted on the upper part of the cover.

Bien que l'on décrive ci-après l'application du dispositif de rebouchage conforme à l'invention au cas des boîtes à boisson cylindriques, il est évident que l'invention s'applique également à tout type de récipient du même genre, contenant notamment des denrées périssables ou des produits altérables. En particulier, certaines boîtes métalliques ou en matière plastique, voire en carton renforcé ou en verre, sont susceptibles d'être équipées d'un dispositif de bouchage adapté à leur géométrie, à leurs dimensions et à leur matière constitutive.Although the application of the filling device according to the invention is described below in the case of cylindrical beverage cans, it is obvious that the invention also applies to any type of container of the same kind, containing especially perishable goods or spoiled products. In particular, certain metal or plastic boxes, or even reinforced cardboard or glass, may be fitted with a closure device adapted to their geometry, their dimensions and their constituent material.

L'exemple d'exécution décrit par la suite est destiné au rebouchage de boîtes à boisson. Une telle boîte comporte un corps 1 et un fond 2, généralement obtenus en une seule passe par emboutissage d'un flan plat en acier doux ou en aluminium, un rétreint 3 étant postérieurement réalisé à proximité du bord supérieur dudit corps pour faciliter notamment l'empilage des boîtes les unes au-dessus des autres. Sur ce rétreint 3, on vient fixer un couvercle 4 par sertissage, lequel est pourvu d'un obturateur frangible 5 qui, une fois déchiré suivant une ligne de moindre résistance exécutée à cet effet, dégage une ouverture 6 permettant à la boisson de s'écouler hors de la boîte. L'arrachage ou le découpage de l'obturateur 5 est généralement opéré au moyen d'une languette de tirage 7, ou clef ; cette dernière, qui est rivetée au centre et au-dessus du couvercle 4, agit par un effet de levier pour chasser l'obturateur 5 vers l'intérieur de la boîte, avant de revenir à sa position initiale.The example of execution described below is intended for the filling of beverage cans. Such a box comprises a body 1 and a bottom 2, generally obtained in a single pass by stamping a flat blank of mild steel or aluminum, a constriction 3 being posteriorly produced near the upper edge of said body to facilitate in particular the stacking boxes one on top of the other. On this constriction 3, a cover 4 is fixed by crimping, which is provided with a frangible shutter 5 which, once torn along a line of least resistance executed for this purpose, releases an opening 6 allowing the drink to s drain out of the box. The uprooting or cutting of the shutter 5 is generally effected by means of a pull tab 7, or key; the latter, which is riveted in the center and above the cover 4, acts by a lever effect to drive the shutter 5 towards the interior of the box, before returning to its initial position.

Suivant l'invention et en référence aux figures 1 et 2, le moyen d'obturation de l'ouverture 6 est constitué d'un étui 8 en forme de secteur angulaire, présentant une face supérieure et une face inférieure au moins reliées par leurs bords latéraux et périphériques, de manière à envelopper au moins partiellement la languette de tirage 7. Le couvercle 4 est ainsi muni d'une patte mobile (7, 8), montée pivotante autour du rivet central 7a qui maintient ladite languette 7 sur la partie supérieure du couvercle 4 ; une fois l'obturateur 5 dégagé, la face inférieure de l'étui 8 peut alors être amenée, de manière pivotante et réversible, en coïncidence avec les bords de l'ouverture 6. L'étanchéité relative recherchée peut, par exemple être obtenue du fait de la matière constituant ladite face inférieure, normalement souple, qui vient se plaquer contre l'ouverture 6, en épousant ses bords à la manière d'un joint glissant.According to the invention and with reference to Figures 1 and 2, the means for closing the opening 6 consists of a case 8 in the form of an angular sector, having an upper face and a lower face at least connected by their edges. lateral and peripheral, so as to at least partially wrap the pull tab 7. The cover 4 is thus provided with a movable tab (7, 8), pivotally mounted around the central rivet 7 a which holds said tab 7 on the part upper cover 4; once the shutter 5 is released, the underside of the case 8 can then be brought, in a pivoting and reversible manner, in coincidence with the edges of the opening 6. The desired relative tightness can, for example, be obtained from made of the material constituting said lower face, normally flexible, which is pressed against the opening 6, by marrying its edges in the manner of a sliding joint.

Selon l'invention, représenté sur la figure 1, l'étui 8 n'est pas fixé à demeure sur la boîte, mais il est rapporté d'une manière amovible sur la languette de tirage 7 de l'obturateur frangible 5, pour venir se fixer, avant ou après l'ouverture de ladite boîte, autour de ladite languette 7.According to the invention, shown in Figure 1, the case 8 is not permanently fixed to the box, but it is attached in a removable manner on the pull tab 7 of the frangible shutter 5, to come be fixed, before or after the opening of said box, around said tab 7.

Conformément à la figure 2, l'étui 8 est alors préférentiellement clippé sur la languette de tirage 7 de l'obturateur frangible 5 et, à cet effet, il est pourvu intérieurement d'un jeu d'ergots 9 de verrouillage venant coopérer avec l'orifice de préhension 10 de ladite languette 7. Une fois enclenchés dans l'orifice 10, ces ergots 9 contribuent à maintenir, au moins provisoirement, l'étui 8 d'une manière ferme autour de ladite languette 7, ce qui permet de faire tourner l'ensemble (7, 8) ainsi constitué autour du rivet central 7a, sans risque d'échappement de l'étui 8.In accordance with FIG. 2, the case 8 is then preferably clipped onto the pulling tab 7 of the frangible shutter 5 and, for this purpose, it is provided internally with a set of locking lugs 9 which cooperate with the gripping orifice 10 of said tongue 7. Once engaged in the orifice 10, these lugs 9 help to maintain, at least temporarily, the case 8 in a firm manner around said tongue 7, which makes it possible to do turn the assembly (7, 8) thus formed around the central rivet 7 a , without risk of escaping from the case 8.

Subsidiairement, on a prévu d'aménager un onglet de préhension 11 sur le bord périphérique extérieur de l'étui 8. Cet onglet 11 facilite la manipulation de l'étui 8 dans tous les cas et permet d'ouvrir la boîte à l'origine si l'étui 8 est monté sur la languette de tirage 7, avant ouverture.Alternatively, provision has been made for a gripping tab 11 on the outer peripheral edge of the case 8. This tab 11 facilitates the handling of the case 8 in all cases and allows the box to be opened. originally if the case 8 is mounted on the pull tab 7, before opening.

D'un autre côté, étant donné que l'on veut obtenir une étanchéité satisfaisante de la boîte une fois ouverte, il ne serait pas suffisant de disposer un étui 8 seulement maintenu par la languette de tirage 7 ; il est donc prévu, suivant la caractéristique principale de l'invention, de conformer le bord périphérique extérieur de l'étui 8, pour qu'il vienne se clipper autour de l'ourlet périphérique de sertissage 12 du couvercle 4 sur le corps 1 de la boîte.On the other hand, since we want to obtain a satisfactory seal of the box once opened, it would not be sufficient to have a case 8 only held by the pull tab 7; it is therefore planned, according to the main characteristic of the invention, to shape the outer peripheral edge of the case 8, so that it clips onto the peripheral crimping hem 12 of the cover 4 on the body 1 of the box.

Ainsi, le moyen d'obturation constitué par l'étui 8 rapporté, sur la languette 7, est maintenu, dans ses déplacements circulaires pour dégager et occulter l'orifice, par ses bords extérieurs, qui sont clippés, et d'autre part, par le rivet central 7a. L'étanchéité obtenue est alors très satisfaisante.Thus, the closure means constituted by the case 8 attached, on the tongue 7, is maintained, in its circular movements to release and obscure the orifice, by its outer edges, which are clipped, and on the other hand, by the central rivet 7 a . The seal obtained is then very satisfactory.

En outre, afin d'améliorer encore cette étanchéité, une feuillure 13 profilée peut être réalisée sous la face inférieure de l'étui 8, pour venir s'engager dans l'encoignure interne en forme de "V" du rétreint 3 et de l'ourlet périphérique de sertissage 12 de la boîte.In addition, in order to further improve this tightness, a profiled rebate 13 can be produced under the underside of the case 8, to engage the internal corner in the "V" shape of the neck 3 and the peripheral hem of crimping 12 of the box.
