Abstract

A cap adapted to cooperate with a container to seal and unseal the container. The cap comprises a circle-shaped knife carried by an inner surface of the cap and a lid adhesively secured to a portion of the inner surface of the cap. The container is sealed by positioning the cap over an opening of the container, which opening is defined by a container edge, and then securing the lid of the cap to the container edge by induction or conduction. The container is unsealed by exerting pressure on the cap whereby the knife cuts through the lid thereby cutting a circular portion out of the lid and unsealing the container. The circular portion cut out the lid remains adhesively secured to the cap.

Description

Cette invention concerne un bouchon destiné à l'obturation par «clipsage» d'un récipient, dont l'orifice est obturé par un opercule solidarisé de celui-ci par induction ou conduction comportant du côté dirigé, en position d'utilisation, vers l'opercule précité, un couteau circulaire destiné à découper l'opercule lorsque le bouchon est enfoncé dans le récipient et le bouchon présentant des saillies servant au clipsage, dit de positionnement et d'utilisation.This invention relates to a stopper intended for closing by "clipping" a container, the orifice of which is closed by a cover secured to it by induction or conduction comprising, on the directed side, in the position of use, towards the 'aforementioned cover, a circular knife for cutting the cover when the cap is pressed into the container and the cap having projections for clipping, said positioning and use.

Le but de l'invention est de réaliser un bouchon qui a, à la fois, les caractéristiques d'un bouchon inviolable qui, de plus, permet la découpe d'un opercule thermoscellable solidarisé de l'orifice du récipient par induction ou conduction.The object of the invention is to produce a stopper which has, at the same time, the characteristics of a tamper-evident stopper which, moreover, allows the cutting of a heat-sealable seal secured to the orifice of the container by induction or conduction.

Il a déjà été proposé de prévoir un couteau circulaire sur la face interne d'un couvercle afin de découper dans l'opercule scellé sur l'orifice du récipient une ouverture par laquelle les produits contenus dans le récipient peuvent être atteints. Un exemple d'un tel récipient et de son bouchon est donné par le brevet britannique 2 127 387.It has already been proposed to provide a circular knife on the internal face of a cover in order to cut in the seal sealed on the orifice of the container an opening through which the products contained in the container can be reached. An example of such a container and its cap is given by British Patent 2,127,387.

Selon ce brevet, le couteau ne provoque pas une découpe parfaitement circulaire de l'opercule. En un point de cet opercule celui-ci n'est pas découpé mais demeure attaché au bord de l'opercule scellé sur l'orifice du récipient. Du fait de la pression exercée sur celui-ci lors de l'opération de découpage et en raison de son poids, la partie découpée pend vers le bas. Il n'est ni pratique, ni hygiénique de laisser cette partie découpée pendre à l'intérieur du récipient. Si on veut empêcher tout contact avec les produits contenus dans celui-ci, il faut écarter cette partie découpée, soit à la main, soit à l'aide d'un ustensile.According to this patent, the knife does not cause a perfectly circular cutting of the cover. At one point of this cover it is not cut but remains attached to the edge of the seal sealed on the orifice of the container. Due to the pressure exerted on it during the cutting operation and due to its weight, the cut part hangs down. It is neither practical nor hygienic to let this cut part hang inside the container. If you want to prevent contact with the products contained therein, you must remove this cut part, either by hand or using a utensil.

Au cours de cette manipulation, la découpe de l'opercule tombe fréquemment dans le récipient, ce qui constitue un désavantage de plus d'un tel moyen . de découpage.During this manipulation, the cutting of the lid frequently falls into the container, which constitutes a disadvantage of more than one such means. cutting.

L'invention a pour but de remédier à cet inconvénient en proposant un bouchon qui permet une découpe parfaitement circulaire de l'opercule tout en empêchant sa chute dans le contenu du récipient.The object of the invention is to remedy this drawback by proposing a stopper which allows a perfectly circular cutting of the cover while preventing it from falling into the contents of the container.

Pour réaliser cet objectif conformément à l'invention, l'opercule précité est solidarisé, en son centre, du bouchon précité.To achieve this objective in accordance with the invention, the aforementioned cover is secured, in its center, to the aforementioned plug.

Selon un mode de réalisation préféré de l'invention, le couteau précité présente un profil en dents de scie arquées.According to a preferred embodiment of the invention, the aforementioned knife has an arched sawtooth profile.

D'autres détails et avantages ressortiront de la description qui sera donnée ci-après d'un bouchon destiné à l'obturation par clipsage d'un récipient dont l'orifice est obturé par un opercule thermoscellable, selon l'invention. Cette description n'est donnée qu'à titre d'exemple et ne limite pas l'invention. Les notations de référence se rapportent aux figures ci-jointes.Other details and advantages will emerge from the description which will be given below of a stopper intended for closing by clipping a container, the orifice of which is closed by a heat-sealable cap, according to the invention. This description is given by way of example only and does not limit the invention. The reference notations refer to the attached figures.

La figure 1 est une vue en coupe du bouchon selon l'invention obturant par clipsage l'orifice d'un récipient muni d'un opercule thermoscellable solidarisé par induction de l'orifice du récipient.Figure 1 is a sectional view of the cap according to the invention closing by clipping the orifice of a container provided with a heat sealable seal secured by induction from the orifice of the container.

La figure 2 est une vue déployée d'une partie du couteau dont est muni le bouchon selon l'invention.Figure 2 is a deployed view of a portion of the knife which is provided with the plug according to the invention.

La figure 3 est une vue en coupe d'un bouchon obturant par clipsage l'orifice d'un récipient muni d'un opercule thermoscellable solidarisé par conduction de l'orifice du récipient.Figure 3 is a sectional view of a plug closing by clipping the orifice of a container provided with a heat-sealable cap secured by conduction of the orifice of the container.

La figure 4 est une vue en coupe du bouchon selon l'invention représenté dans sa position enfoncée par rapport à l'orifice du récipient.Figure 4 is a sectional view of the cap according to the invention shown in its depressed position relative to the orifice of the container.

Avant d'entamer la description détaillée du bouchon selon l'invention, il sera renvoyé aux figures 1 et 3, qui font apparaître les deux procédés de soli- darisation d'un opercule sur l'orifice 2 d'un récipient 3. On entend ici par orifice, l'extrémité du col d'un flacon. Il est entendu que toute autre disposition de l'orifice par rapport au flacon et tout autre profil du flacon rentrent dans le cadre de la présente demande de brevet.Before starting the detailed description of the stopper according to the invention, reference will be made to FIGS. 1 and 3, which show the two methods of joining a cover on the orifice 2 of a container 3. It is intended here by orifice, the end of the neck of a bottle. It is understood that any other arrangement of the orifice relative to the bottle and any other profile of the bottle are within the scope of this patent application.

Selon la figure 1, l'opercule 1 est solidarisé par application de chaleur par induction de l'orifice 2. L'opercule 1 est solidarisé du bouchon 4 par un point de colle 5. Une saillie interne 6 est prévue à l'intérieur de la partie cylindrique 4' du bouchon 4. L'opercule à sceller 1 est appliqué sur le bord supérieur de l'orifice 2 par l'épaulement 4" du bouchon 4. Ceci résulte de la nécessité de réaliser un espace au-dessus de l'orifice 2 pour passer à ce qu'il est convenu d'appeler le cran d'ouverture. Cet appui est réalisé par la présence de l'épaulement 4".According to FIG. 1, the cover 1 is secured by application of heat by induction of the orifice 2. The cover 1 is secured to the plug 4 by a point of glue 5. An internal projection 6 is provided inside the cylindrical part 4 'of the plug 4. The seal 1 is applied to the upper edge of the orifice 2 by the shoulder 4 "of the plug 4. This results from the need to provide a space above the orifice 2 to pass to what is known as the opening notch. This support is achieved by the presence of the shoulder 4 ".

De plus la partie cylindrique 4' du bouchon 4 présente une saillie interne 6 qui coopère avec une saillie externe 7, dite de positionnement ou une saillie externe 8, dite d'utilisation.In addition the cylindrical part 4 'of the plug 4 has an internal projection 6 which cooperates with an external projection 7, called positioning or an external projection 8, called use.

La saillie externe 7, dite de positionnement, maintient le bouchon dans la position dans laquelle l'ensemble est représenté à la figure 1.The external projection 7, called the positioning projection, maintains the plug in the position in which the assembly is shown in FIG. 1.

La saillie externe 8 maintient le bouchon pr rapport au récipient dans la position dite d'utilisation.The external projection 8 maintains the plug pr relative to the container in the so-called use position.

A la base de la partie cylindrique 4' est prévue une bague déchirable 9, munie d'une languette de préhension ou d'arrachage 10, qui empêche que le bouchon soit enfoncé dans l'orifice du récipient qui constitue donc également un temoin indiquant que le bouchon ou la fermeture n'a pas été violé.At the base of the cylindrical part 4 ′ is provided a tearable ring 9, provided with a gripping or tearing tab 10, which prevents the plug from being inserted into the orifice of the container which therefore also constitutes a witness indicating that the stopper or closure has not been breached.

A la partie inférieure du bouchon 4 est prévu un couteau circulaire 11 qui, aussi longtemps que la bague déchirable 9 n'a pas été écartée, ne doit pas entrer en contact avec l'opercule 1.At the lower part of the stopper 4 is provided a circular knife 11 which, as long as the tear-off ring 9 has not been separated, must not come into contact with the cover 1.

Lorsque la bague déchirable 9 a été arrachée, l'utilisateur peut enfoncer le bouchon 4 dont le couteau circulaire 11 va découper l'opercule 1. Pour que cette découpe se fasse aisément et sans effort exagéré, le couteau circulaire 11 présente des dents de scie arquées 12 qui sont visibles à la vue partielle déployée selon la figure 2.When the tearable ring 9 has been torn off, the user can insert the plug 4, the circular knife 11 of which will cut the cover 1. In order for this cutting to be done easily and without exaggerated effort, the circular knife 11 has saw teeth arched 12 which are visible in the partial view deployed according to FIG. 2.

Lorsque le couvercle 4 a été enfoncé et l'opercule 1 découpé, la saillie externe 7 est passée au-delà de la saillie interne 6 et le bouchon est alors retenu grâce à la coopération entre la saillie externe 8 et la saillie interne 6.When the cover 4 has been pushed in and the cover 1 cut, the external projection 7 has passed beyond the internal projection 6 and the plug is then retained thanks to the cooperation between the external projection 8 and the internal projection 6.

Le diamètre externe du couteau circulaire 11 correspond sensiblement au diamètre interne de l'orifice 2 du récipient 3.The external diameter of the circular knife 11 corresponds substantially to the internal diameter of the orifice 2 of the container 3.

Un bouchon réalisé selon le même principe est représenté à la figure 3 où l'on remarque que l'opercule 1 a été solidarisé par conduction sur la saillie 13 délimitant l'orifice du col 14 du récipient 15. Le col du récipient présente une seconde saillie externe 16, tandis que la partie cylindrique 17 du bouchon 18 présente une saillie interne 19 qui est saisie entre les saillies externes 13 et 16 lorsque le bouchon 18 se trouve dans la position représentée à la figure 3, la bague d'arrachage 20, munie d'une languette d'arrachage 21, n'ayant pas encore été séparée du bouchon.A stopper made according to the same principle is re presented in Figure 3 where we note that the cover 1 has been secured by conduction on the projection 13 defining the orifice of the neck 14 of the container 15. The neck of the container has a second external projection 16, while the part cylindrical 17 of the plug 18 has an internal projection 19 which is grasped between the external projections 13 and 16 when the plug 18 is in the position shown in FIG. 3, the tearing ring 20, provided with a tearing tab 21, having not yet been separated from the cap.

Le bouchon 18 selon la figure 3, solidarisé par un point de colle 5 de l'opercule 1 présente également, comme le bouchon 4 de la figure 1, un couteau interne 22 qui peut découper l'opercule 1 lorsqu'on enfonce le bouchon 18 dans l'orifice du récipient 15 après arrachage de la bague 20.The plug 18 according to FIG. 3, joined by a point of glue 5 of the cover 1 also has, like the plug 4 of FIG. 1, an internal knife 22 which can cut the cover 1 when the plug 18 is pushed in. in the orifice of the container 15 after tearing off the ring 20.

Le couteau circulaire 22 présente, tout comme le couteau circulaire 11, les mêmes dents arquées 12 afin que l'enfoncement du bouchon 18 dans le récipient 15 provoque, sans effort particulier, la découpe de l'opercule 1.The circular knife 22 has, like the circular knife 11, the same arcuate teeth 12 so that the insertion of the plug 18 into the container 15 causes, without particular effort, the cutting of the cover 1.

La figure 4 montre le bouchon 18 enfoncé dans le col 14 du récipient 15.FIG. 4 shows the plug 18 pressed into the neck 14 of the container 15.

Dans les formes d'exécution selon les figures 1, 3 ou 4, le diamètre extérieur du couteau circulaire 22 est sensiblement égal au diamètre intérieur de l'orifice du récipient, de telle sorte que lorsque le bouchon a été enfoncé et l'opercule découpé, la surface extérieure du couteau circulaire 1 forme lèvre de rebouchage de l'orifice du récipient.In the embodiments according to Figures 1, 3 or 4, the outside diameter of the circular knife 22 is substantially equal to the inside diameter of the orifice of the container, so that when the cap has been pushed in and the cover cut out , the outer surface of the circular knife 1 forms a lip for filling the orifice of the container.
