Description

L'invention se rapporte à un système de bouchage d'une ouverture d'un récipient, ainsi qu'à un récipient comportant un tel système de bouchage.The invention relates to a system for plugging an opening of a container, as well as a container comprising such a closure system.

Ce système de bouchage est du type comprenant une embase et un bouchon amovible destiné à être vissé ou dévissé sur l'embase.This closure system is of the type comprising a base and a stopper removable intended to be screwed or unscrewed on the base.

L'embase comporte une première partie ayant des moyens d'obturation de l'ouverture, rendus inactifs après la première ouverture et comprenant une paroi de base. L'embase comporte également une deuxième partie ayant un col fileté sur sa face externe et une partie de fixation rigide au récipient.The base comprises a first part having means for closing off the opening, made inactive after the first opening and comprising a wall basic. The base also includes a second part having a threaded neck on its external face and a rigid attachment part to the container.

Le bouchon comporte une paroi transversale et une jupe latérale, filetée sur sa face interne et destinée à coopérer avec le col de l'embase en vue du vissage et dévissage du bouchon.The cap has a transverse wall and a side skirt, threaded on its internal face and intended to cooperate with the neck of the base for screwing and unscrewing the cap.

Des moyens de perforation et de découpe de la paroi de base de l'embase sont attenants à la paroi transversale.Means for perforating and cutting the base wall of the base are adjoining the transverse wall.

De tels systèmes de bouchage sont notamment utilisés sur les récipients, par exemple en forme de brique, comportant en partie supérieure une paroi plate.Such closure systems are used in particular on containers, for example example in the form of a brick, with a flat wall at the top.

Ces récipients sont généralement réalisés en une combinaison de matière plastique, carton et aluminium, tandis que le système de bouchage est en matière plastique.These containers are generally made of a combination of materials plastic, cardboard and aluminum, while the sealing system is in plastic material.

Les systèmes de bouchage existant à l'heure actuelle ne sont pas pratiques à utiliser et n'offrent pas un bon écoulement du contenu du récipient.The existing closure systems are not practical to use and do not offer a good flow of the contents of the container.

De plus, l'étanchéité est parfois insuffisante au rebouchage.In addition, the seal is sometimes insufficient at filling.

Certains récipients nécessitent la présence d'une languette d'aluminium rapportée, scellée sur les bords de l'ouverture. Cependant, ce moyen d'obturation n'est valable que pour la première ouverture et entraíne des coûts supplémentaires. De plus, son retrait se fait manuellement.Some containers require the presence of an aluminum tab attached, sealed on the edges of the opening. However, this means shutter is only valid for the first opening and incurs costs additional. In addition, its removal is done manually.

Suivant d'autres réalisations, l'ouverture du récipient est obturée par une paroi, par exemple en aluminium, scellée également sur les bords de l'ouverture. According to other embodiments, the opening of the container is closed by a wall, for example aluminum, also sealed on the edges of the opening.

Cette paroi est retirée au moment de la première ouverture à l'aide de moyens de perforation et de découpe.This wall is removed at the time of the first opening using means perforation and cutting.

Cependant, ce type de système de bouchage pose un certain nombre d'inconvénients :

  • la partie de la paroi découpée risque de tomber au fond du récipient ;
  • après la première ouverture, l'étanchéité au rebouchage n'est pas suffisante ;
  • les moyens de perforation et de découpe sont souvent peu efficaces.
However, this type of closure system poses a certain number of drawbacks:
  • the part of the cut wall may fall to the bottom of the container;
  • after the first opening, the sealing at the filling is not sufficient;
  • the means of perforation and cutting are often ineffective.

L'invention a donc pour but de pallier les inconvénients de l'art antérieur.The invention therefore aims to overcome the drawbacks of the prior art.

Un objectif de l'invention est de proposer un système de bouchage facilement utilisable par toute personne, y compris les personnes âgées et les enfants.An objective of the invention is to propose an easily plugging system suitable for anyone, including the elderly and children.

Un autre objectif de l'invention est de permettre un écoulement de bonne qualité, et une bonne étanchéité après le rebouchage.Another object of the invention is to allow good flow quality, and a good seal after filling.

Enfin, un autre objectif de l'invention est de permettre une fabrication peu complexe du système de bouchage ainsi que son installation simple sur le récipient, pour un coût minimum.Finally, another objective of the invention is to allow little manufacturing complex closure system as well as its simple installation on the container, for minimum cost.

A cet effet, l'invention propose un système de bouchage du type précité, dans lequel la paroi transversale est reliée à la jupe latérale par une membrane annulaire déformable, permettant le coulissement axial d'enfoncement de la paroi transversale par rapport à la jupe latérale ; la paroi de base étant destinée à être découpée par les moyens de perforation et de découpe, lors du dévissage du bouchon. Les moyens d'obturation comprennent en outre des moyens de retenue associés à la paroi de base, destinés à coopérer avec des moyens complémentaires de retenue du bouchon de manière que, une fois la paroi de base découpée, celle-ci reste associée au bouchon.To this end, the invention provides a closure system of the aforementioned type, in which the transverse wall is connected to the side skirt by a membrane deformable annular, allowing axial sliding of the transverse wall with respect to the side skirt; the base wall being intended to be cut by the perforating and cutting means, during the unscrewing the cap. The sealing means further include retaining means associated with the base wall, intended to cooperate with additional means of retaining the cap so that, once the cut base wall, this remains associated with the plug.

Les moyens de retenue de l'embase ainsi que les moyens complémentaires de retenue du bouchon permettent ainsi un encliquetage des moyens d'obturation dans le bouchon.The means of retaining the base as well as the complementary means of retaining the plug thus allow a snap-fastening of the sealing means in the cap.

Ainsi, les moyens d'obturation ne risquent pas de tomber au fond du récipient et restent par ailleurs en place après le rebouchage. Thus, the closure means are not likely to fall to the bottom of the container and also remain in place after filling.

Suivant un mode de réalisation, les moyens de retenue comprennent au moins une saillie et peuvent être disposés de manière circonférentielle.According to one embodiment, the retaining means comprise at least a protrusion and can be arranged circumferentially.

Ces moyens de retenue appartiennent à une paroi latérale formant jupe attenante à la paroi de base de l'embase.These retaining means belong to a side wall forming a skirt adjoining the base wall of the base.

Les moyens de retenue sont par exemple disposés vers le bord libre de la paroi latérale formant jupe.The retaining means are for example arranged towards the free edge of the wall side forming skirt.

La paroi de base est associée à la deuxième partie de l'embase au moyen de ponts frangibles.The base wall is associated with the second part of the base by means of frangible bridges.

Les moyens complémentaires de retenue comprennent au moins une saillie, et peuvent être disposés de manière circonférentielle.The complementary retaining means comprise at least one projection, and can be arranged circumferentially.

Selon un mode de réalisation de l'invention, une feuille, formant opercule, d'un matériau s'altérant peu à l'air et permettant une étanchéité, telle que par exemple une feuille d'aluminium, est fixée rigidement à la paroi de base, du côté opposé au col fileté.According to one embodiment of the invention, a sheet, forming a cover, of a material which changes little in air and allows a seal, such as by example an aluminum sheet, is rigidly fixed to the base wall, on the side opposite the threaded neck.

Cette feuille formant opercule peut être rapportée et fixée rigidement au récipient ou peut faire partie intégrante du récipient.This sheet forming a cover can be attached and rigidly fixed to the container or may be an integral part of the container.

Dans un tel cas, et dans la mesure où le récipient est réalisé à base de matière plastique, carton et aluminium, la feuille formant opercule résulte de la découpe du carton et de la matière plastique lors de la fabrication du récipient.In such a case, and insofar as the container is made from material plastic, cardboard and aluminum, the foil forming a seal results from cutting cardboard and plastic during the manufacture of the container.

Suivant les modes de réalisation représentés, les moyens de perforation et de découpe comprennent un jupe de maintien attenante à la paroi transversale.According to the embodiments shown, the means of perforation and cutouts include a support skirt adjoining the transverse wall.

Cette jupe de maintien s'étend sensiblement dans la même direction que la jupe latérale.This support skirt extends substantially in the same direction as the skirt lateral.

Elle comporte des moyens formant couteau sensiblement alignés avec la jupe de maintien et attenants au bord libre de celle-ci.It includes knife means substantially aligned with the skirt support and adjoining the free edge thereof.

Selon une première variante de l'invention, les moyens formant couteau sont au moins une dent. According to a first variant of the invention, the knife-forming means are at minus a tooth.

Suivant une deuxième variante de l'invention, les moyens formant couteau sont sensiblement continus et circulaires.According to a second variant of the invention, the knife means are substantially continuous and circular.

De manière à contribuer à l'étanchéité entre le bouchon et l'embase, le système de bouchage comprend une lèvre annulaire.In order to contribute to the seal between the plug and the base, the system closure includes an annular lip.

Ainsi par exemple, le bouchon comprend une lèvre annulaire dans la zone de raccordement entre la jupe latérale et la membrane annulaire déformable. Cette lèvre annulaire est destinée à coopérer avec le col fileté de l'embase.Thus, for example, the stopper includes an annular lip in the area of connection between the side skirt and the deformable annular membrane. This annular lip is intended to cooperate with the threaded neck of the base.

Enfin, on peut prévoir des moyens formant témoin de première ouverture.Finally, one can provide means forming witness of first opening.

Dans une variante, ils sont du type comprenant un premier élément associé au bouchon, par exemple par des pontets frangibles ou analogues, ce premier élément étant destiné à coopérer avec un deuxième élément associé à l'embase.In a variant, they are of the type comprising a first element associated with the cap, for example by frangible bridges or the like, this first element being intended to cooperate with a second element associated with the base.

Dans une seconde variante, les moyens formant témoin comprennent une partie formant coiffe associée de manière amovible à l'embase et recouvrant au moins partiellement le bouchon.In a second variant, the means forming a witness comprise a cap part detachably associated with the base and covering the at least partially the plug.

La partie formant coiffe comprend une paroi de fond disposée en regard de la paroi transversale et comprenant des moyens de préhension ; et une paroi de contour entourant au moins partiellement la paroi latérale.The cap portion includes a bottom wall disposed facing the transverse wall and comprising gripping means; and a wall of contour at least partially surrounding the side wall.

Suivant un autre aspect, l'invention concerne un récipient du type comportant une portion destinée à former une ouverture et comprenant le système de bouchage qui vient d'être défini, la partie de fixation de l'embase étant fixée rigidement au bord de la portion.According to another aspect, the invention relates to a container of the type comprising a portion intended to form an opening and comprising the system of plugging which has just been defined, the fixing part of the base being fixed rigidly at the edge of the portion.

Selon l'invention, la partie du récipient comportant la portion est sensiblement plate.According to the invention, the part of the container comprising the portion is substantially flat.

Selon d'autres caractéristiques, au moins cette partie est réalisée en matière plastique, carton et aluminium. According to other characteristics, at least this part is made of plastic, cardboard and aluminum.

En outre, au niveau de la portion, la matière plastique et le carton sont retirés, la portion ne comportant qu'une pièce en aluminium. La paroi de base de l'embase est fixée rigidement à ladite pièce en aluminium.In addition, at the portion, the plastic and the cardboard are removed, the portion comprising only one aluminum part. The base wall of the base is rigidly fixed to said aluminum part.

D'autres particularités et avantages de l'invention sont décrits en référence aux dessins annexés.Other features and advantages of the invention are described with reference to attached drawings.

La figure 1 représente une vue schématique en coupe longitudinale du système de bouchage de l'invention. La figure 1 est composée de deux parties, gauche et droite, représentant deux variantes du système de bouchage. La partie gauche représente partiellement la position du bouchon par rapport à l'embase avant la perforation. La partie droite représente partiellement la position du bouchon par rapport à l'embase après la perforation.Figure 1 shows a schematic view in longitudinal section of the system closure of the invention. Figure 1 is made up of two parts, left and right, representing two variants of the closure system. The part left partially represents the position of the plug relative to the base before perforation. The right part partially represents the position of the plug relative to the base after the perforation.

La figure 2 représente une vue schématique partielle de dessous du système de bouchage selon le mode de réalisation de la partie droite de la figure 1, suivant la flèche II.Figure 2 shows a partial schematic view from below of the plugging according to the embodiment of the right part of FIG. 1, according to arrow II.

La figure 3 représente une vue schématique en perspective d'un mode de réalisation du bouchon de l'invention.FIG. 3 represents a schematic perspective view of a mode of realization of the plug of the invention.

La figure 4 est une vue schématique partielle en coupe longitudinale, représentant un mode de réalisation d'un système de bouchage fixé à un récicpient.FIG. 4 is a partial schematic view in longitudinal section, representing an embodiment of a closure system attached to a reluctant.

Les figures 5 et 6 représentent deux vues schématiques, respectivement en coupe longitudinale et de dessus, d'un autre mode de réalisation du système de bouchage.Figures 5 and 6 show two schematic views, respectively in longitudinal and top section of another embodiment of the capping.

En référence à la figure 1, le système de bouchage 1 comporte une embase 2 et un bouchon 3, adaptés à coopérer l'un avec l'autre par vissage et dévissage du bouchon 3, sur l'embase 2.Referring to Figure 1, the closure system 1 includes a base 2 and a plug 3, adapted to cooperate with each other by screwing and unscrewing plug 3, on base 2.

Dans les présents modes de réalisation, le système de bouchage 1, c'est-à-dire l'embase 2 et le bouchon 3, est réalisé en matière plastique, tel que par exemple du polyéthylène à haute densité.In the present embodiments, the closure system 1, that is to say the base 2 and the plug 3, is made of plastic, such as by example of high density polyethylene.

L'embase 2 comporte une première partie 4 et une deuxième partie 5. The base 2 has a first part 4 and a second part 5.

La première partie 4 comprend une paroi de base 6 de contour sensiblement circulaire.The first part 4 comprises a base wall 6 of substantially contour circular.

La paroi de base 6 est délimitée circonférentiellement par une paroi latérale formant jupe 7 faisant saillie d'un côté de la paroi de base 6.The base wall 6 is delimited circumferentially by a side wall forming a skirt 7 projecting from one side of the base wall 6.

Du côté opposé à la paroi formant jupe 7, la paroi de base 6 comprend une rainure circulaire 8 située vers son bord.On the side opposite to the skirt wall 7, the base wall 6 comprises a circular groove 8 located towards its edge.

En outre, à l'intérieur de la première partie 4, c'est-à-dire à l'intérieur de la paroi formant jupe 7, la paroi de base 6 comprend une gorge 9, en forme de disque, et de profondeur sensiblement égale à celle de la rainure circulaire 8.In addition, inside the first part 4, that is to say inside the wall forming a skirt 7, the base wall 6 comprises a groove 9, in the form of a disc, and of depth substantially equal to that of the circular groove 8.

Dans le mode de réalisation de la figure 1, la profondeur de la gorge 9 et celle de la rainure circulaire 8 sont chacune de l'ordre de la moitié de l'épaisseur totale de la paroi de base 6.In the embodiment of Figure 1, the depth of the groove 9 and that of the circular groove 8 are each about half the thickness total of the base wall 6.

La gorge 9 se trouve en partie centrale de la paroi de base 6, et à distance de la rainure circulaire 8, toutes deux étant ménagées sur des faces opposées de la paroi de base 6.The groove 9 is located in the central part of the base wall 6, and at a distance from the circular groove 8, both being formed on opposite faces of the base wall 6.

La deuxième partie 5 de l'embase 2 comprend un col 10 fileté sur sa face externe 10a, et une partie de fixation rigide 11 au récipient.The second part 5 of the base 2 comprises a neck 10 threaded on its face external 10a, and a rigid fixing part 11 to the container.

La deuxième partie 5 entoure la première partie 4 et y est associée au moyen de ponts frangibles 12.The second part 5 surrounds the first part 4 and is associated therewith by means frangible bridges 12.

Dans une variante, on pourrait prévoir que les parties 4 et 5 soient associées entre elles au moyen d'une membrane frangible.Alternatively, provision could be made for parts 4 and 5 to be associated between them by means of a frangible membrane.

Le col 10 s'étend à partir de la partie de fixation 11, du même côté que la paroi latérale formant jupe 7 et dans la même direction D.The neck 10 extends from the fixing part 11, on the same side as the wall side forming skirt 7 and in the same direction D.

Plus précisément, le col 10 et la paroi formant jupe 7 se trouvent en regard l'un de l'autre et à proximité, en étant séparés par les ponts frangibles 12. More specifically, the neck 10 and the skirt wall 7 are located opposite one on the other and nearby, being separated by frangible bridges 12.

A cet effet, la face interne 10b du col 10 est en regard de la face externe 7c de la paroi formant jupe 7.To this end, the internal face 10b of the neck 10 is opposite the external face 7c of the wall forming a skirt 7.

Par ailleurs, la paroi de base 6 est sensiblement coplanaire avec la partie de fixation 11.Furthermore, the base wall 6 is substantially coplanar with the part of fixing 11.

La partie de fixation 11 présente une forme d'anneau, portant, du côté de son bord intérieur 11a, le col fileté 10.The fixing part 11 has the shape of a ring, carrying, on the side of its inner edge 11a, the threaded neck 10.

Dans une autre réalisation, la partie de fixation 11 pourrait présenter une forme de manchon de section sensiblement carrée ou rectangulaire ou toute autre forme.In another embodiment, the fixing part 11 could have a shape of sleeve of substantially square or rectangular section or any other form.

Dans les variantes représentées, les ponts frangibles 12 sont attenants à ce bord intérieur 11a.In the variants shown, the frangible bridges 12 are attached to this inner edge 11a.

Dans le mode de réalisation de la figure 1, la partie de fixation 11 comporte, du côté opposé au col 10, une rainure centrale annulaire 11b.In the embodiment of FIG. 1, the fixing part 11 comprises, from the opposite side to the neck 10, an annular central groove 11b.

Cette rainure centrale annulaire 11b se trouve ainsi du même côté que la rainure circulaire 8.This annular central groove 11b is thus on the same side as the circular groove 8.

La face interne 10b du col 10 est inclinée en direction du bord libre 10c -situé du côté opposé à la partie de fixation 11- du col 10.The internal face 10b of the neck 10 is inclined towards the free edge 10c -located opposite side to the fixing part 11- of the neck 10.

En outre, la face externe 10a du col 10 s'étend sensiblement perpendiculairement au plan de la partie de fixation 11, sensiblement parallèlement à la direction D de la paroi formant jupe 7.In addition, the external face 10a of the neck 10 extends substantially perpendicular to the plane of the fixing part 11, substantially parallel to direction D of the skirt wall 7.

Dans la variante représentée sur la partie droite de la figure 1, ainsi que sur la figure 2, la partie de fixation 11 est prolongée à partir de son bord extérieur 11c, c'est-à-dire du côté opposé au bord intérieur 11a, par une paroi circulaire 13, s'étendant dans la même direction D et du même côté que le col 10.In the variant shown on the right-hand side of FIG. 1, as well as on the FIG. 2, the fixing part 11 is extended from its outer edge 11c, that is to say on the side opposite the inner edge 11a, by a circular wall 13, extending in the same direction D and on the same side as the neck 10.

De manière à réaliser des moyens formant témoin de première ouverture, cette paroi circulaire 13 est adaptée à coopérer avec un anneau 22 associé au bouchon 3, comme il sera vu plus loin. In order to produce means forming a witness of first opening, this circular wall 13 is adapted to cooperate with a ring 22 associated with the plug 3, as will be seen later.

Des moyens de retenue 7' sont disposés sur la face externe 7c de la paroi latérale formant jupe 7 vers son bord libre 7a, du côté opposé à la paroi de base 6.Retaining means 7 'are arranged on the external face 7c of the wall side forming a skirt 7 towards its free edge 7a, on the side opposite to the base wall 6.

Ces moyens de retenue 7' se présentent sous la forme d'une saillie sensiblement continue circulaire, s'étendant de manière circonférentielle autour du bord libre 7a et dirigée suivant une direction sensiblement perpendiculaire à celle de la paroi latérale formant jupe 7.These retaining means 7 'are in the form of a projection substantially continuous circular, extending circumferentially around from the free edge 7a and directed in a direction substantially perpendicular to that of the side wall forming a skirt 7.

Le bouchon 3 comporte une jupe latérale 14, filetée sur une partie au moins de sa face interne 14a. Cette jupe latérale 14 est destinée à coopérer au moyen de sa partie filetée 14' avec le filetage du col 10 de l'embase 2, en vue de visser ou dévisser le bouchon 3 sur l'embase 2.The plug 3 comprises a side skirt 14, threaded on at least part of its internal face 14a. This side skirt 14 is intended to cooperate by means of its threaded portion 14 'with the thread of the neck 10 of the base 2, for screwing or unscrew the plug 3 on the base 2.

Plus précisément, la jupe latérale 14 comporte un filetage sur la partie 14' représentant la moitié de sa hauteur -comptée suivant la direction générale D de la jupe latérale 14- à partir de son bord libre 14b.More specifically, the side skirt 14 has a thread on the part 14 ' representing half of its height - counted in the general direction D of the side skirt 14- from its free edge 14b.

Le bouchon 3 comporte également une paroi transversale 15 de contour sensiblement circulaire.The plug 3 also has a transverse wall 15 of outline substantially circular.

Dans les variantes des figures 1 à 4, elle est sensiblement plane, tandis que dans la variante des figures 5 et 6, elle comporte un épaulement central 15' présentant une concavité tournée vers l'extérieur du bouchon 3.In the variants of FIGS. 1 to 4, it is substantially planar, while in the variant of Figures 5 and 6, it has a central shoulder 15 ' having a concavity turned towards the outside of the plug 3.

La paroi transversale 15 est délimitée circonférentiellement par des moyens de perforation et de découpe 16.The transverse wall 15 is delimited circumferentially by means of punching and cutting 16.

Ces moyens de perforation et de découpe 16 comprennent une jupe de maintien 17, de forme sensiblement cylindrique, faisant saillie d'un côté de la paroi transversale 15 et s'étendant dans une direction D sensiblement perpendiculaire à la dite paroi transversale 15.These perforation and cutting means 16 comprise a skirt of support 17, of substantially cylindrical shape, projecting from one side of the transverse wall 15 and extending in a direction D substantially perpendicular to said transverse wall 15.

La jupe de maintien 17 et la jupe latérale 14 s'étendent suivant la même direction D, la jupe de maintien 17 s'étendant à l'intérieur de la jupe latérale 14.The holding skirt 17 and the side skirt 14 extend along the same direction D, the holding skirt 17 extending inside the side skirt 14.

Du côté opposé à la paroi transversale 15, la jupe de maintien 17 est prolongée, à partir de son bord libre 17a, par des moyens formant couteau 18. On the side opposite to the transverse wall 15, the retaining skirt 17 is extended, from its free edge 17a, by means forming a knife 18.

Comme représenté sur la figure 3, les moyens formant couteau 18 se présentent sous la forme de dents, espacées les unes des autres et au nombre de quatre dans la variante représentée. Ce nombre n'est bien entendu pas limitatif.As shown in Figure 3, the knife means 18 is are in the form of teeth, spaced from one another and in number of four in the variant shown. This number is of course not limiting.

Les dents 18 présentent une forme sensiblement trapézoïdale avec deux premier et deuxième bords inclinés 18a, 18b et deux bords parallèles 18c, 18d.The teeth 18 have a substantially trapezoidal shape with two first and second inclined edges 18a, 18b and two parallel edges 18c, 18d.

Le bord 18d est sensiblement confondu avec le bord libre 17a de la jupe de maintien 17. En outre, le premier bord incliné 18a est légèrement incliné de quelques degrés par rapport à la direction D et le deuxième bord incliné 18b présente un angle de l'ordre de 45° par rapport à la direction D.The edge 18d is substantially coincident with the free edge 17a of the skirt of holding 17. In addition, the first inclined edge 18a is slightly inclined by a few degrees from direction D and the second inclined edge 18b has an angle of around 45 ° to direction D.

Le premier bord incliné 18a est situé de sorte qu'il soit le premier bord à entrer en contact avec la surface à découper lors du dévissage du bouchon 3 par rapport à l'embase 2.The first inclined edge 18a is located so that it is the first edge to enter in contact with the surface to be cut when unscrewing the plug 3 by compared to base 2.

On peut en outre envisager que les moyens formant couteau 18 soient sensiblement continus et circulaires.It can also be envisaged that the knife means 18 are substantially continuous and circular.

Des moyens complémentaires de retenue 17' sont disposés sur la face interne 17c de la jupe de maintien 17 vers son bord libre 17a, à partir duquel s'étendent les moyens formant couteau 18.Additional retaining means 17 ′ are arranged on the internal face 17c from the holding skirt 17 towards its free edge 17a, from which extend the knife means 18.

Bien entendu, les moyens complémentaires de retenue 17' pourraient également être disposés sur les moyens formant couteau 18.Of course, the additional retaining means 17 'could also be arranged on the knife means 18.

Ces moyens complémentaires de retenue 17' se présentent sous la forme de saillies sensiblement rectilignes. Ces saillies 17' s'étendent sensiblement parallèlement au bord libre 17a et sont écartées les unes des autres (voir figure 3).These additional retaining means 17 'are in the form of substantially straight protrusions. These projections 17 'extend substantially parallel to the free edge 17a and are spaced from each other (see figure 3).

Les saillies 17' sont dirigées suivant une direction sensiblement perpendiculaire à celle de la jupe de maintien 17.The protrusions 17 'are directed in a substantially perpendicular direction to that of the holding skirt 17.

Dans le mode de réalisation représenté, elles sont au nombre de quatre. In the embodiment shown, there are four of them.

La jupe de maintien 17 est associée à la face interne 14a de la jupe latérale 14 au moyen d'une membrane annulaire déformable 19.The holding skirt 17 is associated with the internal face 14a of the side skirt 14 by means of a deformable annular membrane 19.

La membrane annulaire déformable 19 est réalisée en une matière plus souple que celle du bouchon 3 et de l'embase 2.The deformable annular membrane 19 is made of a more flexible material than that of plug 3 and base 2.

Elle présente une forme sensiblement tronconique (figures 1 et 4).It has a substantially frustoconical shape (Figures 1 and 4).

Elle comporte ainsi un premier bord 19a délimitant la grande base du tronc de cône et un deuxième bord 19b délimitant la petite base du tronc de cône.It thus has a first edge 19a delimiting the large base of the trunk of cone and a second edge 19b delimiting the small base of the truncated cone.

Le premier bord 19a est attenant à la face interne 14a de la jupe latérale 14, tandis que le deuxième bord 19b est attenant à la face externe 17b de la jupe de maintien 17.The first edge 19a is adjacent to the internal face 14a of the side skirt 14, while the second edge 19b is attached to the external face 17b of the skirt holding 17.

Il est à noter que dans le mode de réalisation représenté, le bouchon 3 est réalisé d'un seul tenant.It should be noted that in the embodiment shown, the plug 3 is made in one piece.

Le premier bord 19a est plus précisément attenant à la partie centrale 14d de la face interne 14a de la jupe latérale 14, c'est-à-dire à la limite entre la partie filetée 14' et la partie non filetée.The first edge 19a is more precisely adjoining the central part 14d of the internal face 14a of the side skirt 14, that is to say at the limit between the part threaded 14 'and the unthreaded part.

Par ailleurs, le deuxième bord 19b est situé vers la paroi transversale 15.Furthermore, the second edge 19b is located towards the transverse wall 15.

Le bouchon 3 comporte en outre une lèvre annulaire 20 dans la zone de raccordement 19' entre la jupe latérale 14 et la membrane annulaire 19.The plug 3 further comprises an annular lip 20 in the area of connection 19 'between the side skirt 14 and the annular membrane 19.

Cette lèvre annulaire 20 est sensiblement attenante au premier bord 19a du côté de la partie filetée 14' de la jupe latérale 14. Elle est également réalisée en une matière déformable.This annular lip 20 is substantially adjacent to the first edge 19a of the side of the threaded portion 14 'of the side skirt 14. It is also made of a deformable material.

Au repos, la lèvre annulaire 20 s'étend de manière inclinée par rapport à la direction D, et est dirigée vers le centre du bouchon 3, vers le bord libre 14b.At rest, the annular lip 20 extends in an inclined manner relative to the direction D, and is directed towards the center of the plug 3, towards the free edge 14b.

La lèvre annulaire 20 est destinée à reposer sur le bord libre 10c du col 10 de l'embase, lorsque le bouchon 3 est vissé sur l'embase 2. The annular lip 20 is intended to rest on the free edge 10c of the neck 10 of the base, when the plug 3 is screwed onto the base 2.

Selon une variante (non représentée), on peut prévoir que ce soit l'embase 2 qui comporte une telle lèvre annulaire, ayant les mêmes fonctions, et non le bouchon 3.According to a variant (not shown), provision may be made for the base 2 which has such an annular lip, having the same functions, and not the plug 3.

Dans un mode de réalisation particulier, la face externe de la jupe latérale 14 comporte des goderons ou reliefs équivalents G, destinés à faciliter le vissage ou le dévissage du bouchon 3.In a particular embodiment, the external face of the lateral skirt 14 has G-shaped flutes or equivalent reliefs, intended to facilitate screwing or unscrewing the cap 3.

Par ailleurs, comme représenté dans la variante de la partie droite de la figure 1, le bouchon 3 comporte un anneau 22, associé par des pontets frangibles 23 ou analogues, au bord libre 14b de la jupe latérale 14, du côté de sa face externe.Furthermore, as shown in the variant on the right side of the figure 1, the plug 3 comprises a ring 22, associated by frangible bridges 23 or the like, at the free edge 14b of the side skirt 14, on the side of its face external.

Cet anneau 22 est du type mortaise, adapté à recevoir à force la partie extrême libre 13a de la paroi circulaire 13.This ring 22 is of the mortise type, adapted to forcibly receive the extreme part free 13a of the circular wall 13.

Plus précisément, l'anneau 22 comporte un canal central borgne 22a présentant une ouverture 22b s'étendant sensiblement dans le plan comportant le bord libre 14b.More specifically, the ring 22 comprises a blind central channel 22a having an opening 22b extending substantially in the plane comprising the edge free 14b.

Le canal 22a présente une forme intérieure sensiblement complémentaire à la partie extrême libre 13a de la paroi circulaire 13.The channel 22a has an interior shape substantially complementary to the free end 13a of the circular wall 13.

Les figures 5 et 6 sont relatives à un autre mode de réalisation des moyens formant témoin de première ouverture 21.Figures 5 and 6 relate to another embodiment of the means forming witness of first opening 21.

Ces moyens formant témoin 21 comportent une partie formant coiffe 27, recouvrant au moins pour partie le bouchon 3 et attenante à l'embase 2, tout en étant amovible par rapport à celle-ci.These control means 21 comprise a cap part 27, covering at least partially the plug 3 and adjoining the base 2, while being removable from it.

La partie formant coiffe 27 comporte une paroi de recouvrement transversale 28 et une paroi latérale 29.The cap portion 27 has a transverse covering wall 28 and a side wall 29.

La paroi de recouvrement 28 s'étend sensiblement parallèlement et en regard de la paroi transversale 15 et dépasse de part et d'autre du bord 14c de la jupe latérale 14. The covering wall 28 extends substantially parallel and opposite from the transverse wall 15 and protrudes on either side of the edge 14c of the skirt lateral 14.

La paroi de recouvrement 28 est attenante par deux bords opposés 28c, 28d à la paroi latérale 29.The covering wall 28 is attached by two opposite edges 28c, 28d to the side wall 29.

La paroi latérale 29 comporte deux portions 29', 29" en regard, entourant pour partie la jupe latérale 14.The side wall 29 has two facing portions 29 ′, 29 ″, surrounding for part of the side skirt 14.

Il est entendu que dans une autre réalisation, la paroi latérale 29 pourrait présenter une section transversale sensiblement rectangulaire, ou cylindrique entourant la jupe latérale 14.It is understood that in another embodiment, the side wall 29 could have a substantially rectangular or cylindrical cross section surrounding the side skirt 14.

Chaque portion 29', 29" de la paroi latérale 29 présente une hauteur -comptée suivant la direction D- telle que son bord libre 29a puisse venir en contact avec le bord 11' de la partie de fixation 11 qui est adjacente au bord externe 11c et au col 10.Each portion 29 ′, 29 ″ of the side wall 29 has a height -counted in the direction D- such that its free edge 29a can come into contact with the edge 11 'of the fixing part 11 which is adjacent to the outer edge 11c and at pass 10.

Les bords 29a sont reliés à la paroi de fixation 11 d'une part, s'agissant de la portion 29', par des zones frangibles 30, tels que des ponts, et d'autre part, s'agissant de la portion 29", par des moyens d'association rigide mais amovible 31.The edges 29a are connected to the fixing wall 11 on the one hand, as regards the portion 29 ′, by frangible zones 30, such as bridges, and on the other hand, in the case of the 29 "portion, by means of rigid but removable association 31.

Les moyens d'association 31 comprennent deux crochets 31a, 31b adaptés à s'encliqueter l'un avec l'autre (figure 5).The association means 31 comprise two hooks 31a, 31b adapted to snap together (Figure 5).

Le crochet 31a fait partie intégrante du bord libre 29a et est dirigé vers l'extérieur, c'est-à-dire du côté opposé au système de bouchage 1.The hook 31a is an integral part of the free edge 29a and is directed towards the outside, that is to say on the side opposite to the closure system 1.

En outre, le crochet 31b est attenant au bord 11'. Il comporte deux portions de paroi 32, 33, perpendiculaires l'une par rapport à l'autre.In addition, the hook 31b is attached to the edge 11 '. It has two portions of wall 32, 33, perpendicular to one another.

La portion 32 s'étend suivant la direction D à partir du bord 11', c'est-à-dire sensiblement parallèlement à la direction générale de la paroi latérale 29.The portion 32 extends in the direction D from the edge 11 ', that is to say substantially parallel to the general direction of the side wall 29.

En outre, la portion 33 s'étend en direction du système de bouchage 1.In addition, the portion 33 extends in the direction of the closure system 1.

Les dimensions des portions 32 et 33 sont choisies de sorte que le crochet 31a puisse venir s'encliqueter dans le crochet 31b, par coopération entre le crochet 31a et la portion 33. The dimensions of the portions 32 and 33 are chosen so that the hook 31a can snap into the hook 31b, by cooperation between the hook 31a and portion 33.

Comme représenté dans la figure 6, la paroi de recouvrement 28 présente une forme générale rectangulaire, ayant deux grands côtés 28a et 28b et deux petits côtés 28c et 28d.As shown in Figure 6, the cover wall 28 has a general rectangular shape, having two long sides 28a and 28b and two small sides sides 28c and 28d.

Le côté 28c est situé du côté des ponts frangibles 30 tandis que le côté 28d est situé du côté des moyens de fixation 31.The side 28c is located on the side of the frangible bridges 30 while the side 28d is located on the side of the fixing means 31.

La paroi de recouvrement 28 s'étend généralement de manière centrale par rapport au système de bouchage 1.The covering wall 28 generally extends centrally by with respect to the closure system 1.

Le grand côté 28b est prolongé par une patte de préhension 34 de forme générale triangulaire arrondie.The large side 28b is extended by a gripping tab 34 of shape general rounded triangular.

Cette patte 34 permet à l'utilisateur de saisir la paroi de recouvrement 28 de manière à déchirer les ponts frangibles 30, puis à désolidariser les moyens d'association 31.This tab 34 allows the user to grasp the covering wall 28 of so as to tear the frangible bridges 30, then to separate the means of association 31.

La membrane annulaire déformable 19 permet le coulissement axial d'enfoncement par une simple pression manuelle, des moyens de perforation et de découpe 16 par rapport à la jupe latérale 14.The deformable annular membrane 19 allows axial sliding driven by simple manual pressure, perforation means and cutting 16 relative to the side skirt 14.

Il est entendu qu'on pourrait envisager dans un autre mode de réalisation que l'enfoncement ne se fasse que sur une partie de la paroi transversale 15. Dans un tel cas, la membrane déformable 19 et les moyens de perforation et de découpe 16 ne seraient disposés que sur une partie de la paroi transversale 15 et non sur son pourtour, comme c'est le cas dans les présents modes de réalisation.It is understood that one could envisage in another embodiment that the penetration only takes place on part of the transverse wall 15. In such a case, the deformable membrane 19 and the means of perforation and cutout 16 would only be arranged on part of the transverse wall 15 and not on its periphery, as is the case in the present modes of production.

La partie gauche de la figure 1, ainsi que les figures 3, 5 et 6, représentent la position -appelée position haute- des moyens de perforation et de découpe 16 par rapport à la jupe latérale 14, avant l'enfoncement des moyens de perforation et de découpe 16.The left part of figure 1, as well as figures 3, 5 and 6, represent the position - called upper position - of the perforation and cutting means 16 relative to the side skirt 14, before the insertion of the perforation means and cutting 16.

Dans cette position haute, la paroi transversale 15 s'étend à un niveau légèrement inférieur (sur la figure 1) au plan P défini par le bord 14c de la jupe latérale 14, situé du côté opposé au bord libre 14b. Ainsi, le bord 14c dépasse la paroi transversale 15. In this high position, the transverse wall 15 extends at a level slightly lower (in FIG. 1) than the plane P defined by the edge 14c of the skirt lateral 14, located on the side opposite the free edge 14b. Thus, the edge 14c exceeds the transverse wall 15.

Cette différence de hauteur est de l'ordre de l'épaisseur de la paroi transversale 15.This difference in height is of the order of the thickness of the transverse wall 15.

De plus, les moyens formant couteau 18 dépassent, sensiblement d'une même hauteur, le bord libre 14b de la jupe latérale 14.In addition, the knife means 18 protrude substantially by the same height, the free edge 14b of the side skirt 14.

On notera que la hauteur -comptée suivant la direction D- de la jupe de maintien 17 prolongée par les dents 18 est sensiblement la même que celle de la jupe latérale 14.Note that the height -counted in the direction D- of the support skirt 17 extended by the teeth 18 is substantially the same as that of the skirt lateral 14.

D'autre part, dans cette position, le deuxième bord 19b de la membrane déformable 19 est plus proche du plan P que ne l'est le premier bord 19a.On the other hand, in this position, the second edge 19b of the membrane deformable 19 is closer to the plane P than is the first edge 19a.

La partie droite de la figure 1 représente la position -appelée position basse-des moyens de perforation et de découpe 16 par rapport à la jupe latérale 14, après enfoncement -c'est-à-dire le déplacement axial relatif suivant la direction D- des moyens de perforation et de découpe 16.The right part of figure 1 represents the position - called low position - of perforation and cutting means 16 relative to the side skirt 14, after pressing - i.e. the relative axial displacement in the direction D- means for perforation and cutting 16.

Dans cette position basse, la paroi transversale 15 est éloignée du plan P et se situe sensiblement vers la partie centrale 14d de la jupe latérale 14.In this low position, the transverse wall 15 is distant from the plane P and is located substantially towards the central part 14d of the side skirt 14.

En outre, le deuxième bord 19b de la membrane déformable 19 est plus éloigné du plan P que ne l'est le premier bord 19a.In addition, the second edge 19b of the deformable membrane 19 is more distant of plane P than is the first edge 19a.

Lorsque le bouchon 3 est vissé sur l'embase 2 (figures 1 et 4), le bord libre 14b de la jupe latérale 14 est en regard et légèrement en contact avec le bord 11' de la partie de fixation 11 qui est adjacent au bord externe 11c et au col 10.When the plug 3 is screwed onto the base 2 (Figures 1 and 4), the free edge 14b of the side skirt 14 is facing and slightly in contact with the edge 11 'of the fixing part 11 which is adjacent to the outer edge 11c and to the neck 10.

En outre, le bord libre 10c du col 10, ainsi que le bord libre 7a de la paroi latérale formant jupe 7 se trouvent sensiblement dans la partie centrale 14d de la jupe latérale 14.In addition, the free edge 10c of the neck 10, as well as the free edge 7a of the wall side forming skirt 7 are located substantially in the central part 14d of the side skirt 14.

Enfin, la jupe de maintien 17 s'étend entre le col 10 et la paroi formant jupe 7, le bord libre des moyens formant couteau 18 étant en regard des ponts frangibles 12.Finally, the holding skirt 17 extends between the neck 10 and the wall forming the skirt 7, the free edge of the knife-forming means 18 facing frangible bridges 12.

Comme représenté sur la partie gauche de la figure 1, les moyens de retenue 7' et les moyens complémentaires de retenue 17' sont en butée l'un contre l'autre, ce qui permet de retenir la premième partie 4 de l'embase 2, à l'intérieur des moyens de perforation et de découpe 16.As shown on the left side of Figure 1, the retaining means 7 ' and the complementary retaining means 17 'are in abutment against each other, which allows to retain the first part 4 of the base 2, inside the punching and cutting means 16.

Suivant un mode de réalisation particulier, on peut prévoir sur la membrane déformable 19, des moyens de repérage de celle-ci, tels que par exemple des décors ou analogue, de manière à rendre visible la position basse.According to a particular embodiment, one can provide on the membrane deformable 19, means for locating the latter, such as for example decorations or the like, so as to make the low position visible.

On décrit ci-après le procédé d'ouverture d'un récipient R comportant le système de bouchage 1 qui vient d'être décrit.The method of opening a container R comprising the closure system 1 which has just been described.

Ce récipient R comporte au moins une partie plate 24, réalisée par exemple en matière plastique, carton et aluminium.This container R comprises at least one flat part 24, made for example of plastic, cardboard and aluminum.

Il peut s'agir par exemple d'un récipient en forme de brique.It may for example be a container in the form of a brick.

La partie plate 24 comprend une portion 25 destinée à former l'ouverture du récipient R.The flat part 24 comprises a portion 25 intended to form the opening of the container R.

Dans le mode de réalisation de la figure 4, cette portion 25 est de contour sensiblement circulaire, de manière à former une ouverture circulaire. On peut néanmoins prévoir que l'ouverture soit sensiblement carrée ou rectangulaire ou autre.In the embodiment of FIG. 4, this portion 25 is of contour substantially circular, so as to form a circular opening. We can nevertheless provide that the opening is substantially square or rectangular or other.

Dans la variante représentée, la portion 25 comprend une pièce d'aluminium.In the variant shown, the portion 25 comprises an aluminum piece.

Cette pièce d'aluminium peut être soit rapportée, soit intégrée à la partie plate 24, après enlèvement localement de la partie en carton et/ou de la partie en matière plastique au niveau de la portion 25, le cas échéant.This piece of aluminum can be either attached or integrated into the flat part 24, after local removal of the cardboard part and / or the plastic material at portion 25, if applicable.

Comme représenté sur la figure 4, l'embase 2 du système de bouchage 1 est fixée à la partie plate 24.As shown in Figure 4, the base 2 of the closure system 1 is fixed to the flat part 24.

Plus précisément, la paroi de base 6 est fixée rigidement, par exemple par collage ou scellage, à la pièce d'aluminium 25.More specifically, the base wall 6 is rigidly fixed, for example by gluing or sealing, using aluminum 25.

Les ponts frangibles 12 sont également en regard de la portion 25. The frangible bridges 12 are also opposite the portion 25.

En outre, la partie de fixation 11 est fixée rigidement, par exemple par collage,-sensiblement en même temps que la paroi de base 6- et de manière étanche au bord 26 délimitant la portion 25.In addition, the fixing part 11 is rigidly fixed, for example by gluing, -sensibly at the same time as the base wall 6- and sealingly edge 26 delimiting the portion 25.

Suivant un autre mode de réalisation, la portion 25 pourrait être obturée de manière étanche, directement par la paroi de base 6. Dans un tel cas, la paroi de base 6 serait associée à la seconde partie 5 non pas par des ponts frangibles mais par une paroi annulaire étanche et frangible notamment par les dents 18.According to another embodiment, the portion 25 could be closed with tightly, directly through the base wall 6. In such a case, the wall basic 6 would be associated with the second part 5 not by bridges frangible but by a sealed and frangible annular wall in particular by the teeth 18.

Le bouchon 3 est préalablement vissé sur l'embase 2.The plug 3 is previously screwed onto the base 2.

Pour la première ouverture du récipient R, on enfonce manuellement, par simple pression, la paroi transversale 15.For the first opening of the container R, it is pressed manually, by simple pressure, the transverse wall 15.

Les dents 18 pénètrent alors au travers des ponts frangibles 12, puis dans la pièce d'aluminium 25.The teeth 18 then penetrate through frangible bridges 12, then into the piece of aluminum 25.

Puis en dévissant le bouchon 3, les dents 18 décrivent un mouvement circulaire dans la pièce d'aluminium, vers le bord 26.Then by unscrewing the plug 3, the teeth 18 describe a circular movement in the aluminum piece, towards edge 26.

A la fin du dévissage, les ponts frangibles 12 sont totalement rompus, la première partie 4 de l'embase 2 est alors séparée de la deuxième partie 5. Par ailleurs, la pièce d'aluminium est découpée et reste attenante à la paroi de base 6.At the end of the unscrewing, the frangible bridges 12 are completely broken, the first part 4 of the base 2 is then separated from the second part 5. By elsewhere, the piece of aluminum is cut and remains attached to the base wall 6.

En outre, la première partie 4 -à savoir, la paroi de base 6 à laquelle est fixée la pièce d'aluminium 25, ainsi que la paroi formant jupe 7- reste encliquetée dans la jupe de maintien 17 grâce au blocage des moyens de retenue 7' avec les moyens de retenue complémentaires 17'.In addition, the first part 4 - namely, the base wall 6 to which the piece of aluminum 25, as well as the skirt wall 7- remains snapped into the holding skirt 17 by blocking the retaining means 7 'with the additional retaining means 17 '.

On notera que les diamètres de la jupe de maintien 17 et de la paroi formant jupe 7, ainsi que les dimensions des moyens 7' et 17' doivent être tels qu'ils permettent cet encliquetage.It will be noted that the diameters of the holding skirt 17 and of the wall forming skirt 7, as well as the dimensions of the means 7 'and 17' must be such that they allow this snap-fastening.

Lorsque les moyens de perforation et découpe 16 sont enfoncés (partie droite de la figure 1), la paroi transversale 15 vient en butée contre le bord libre 7a de la paroi latérale formant jupe 7, tandis que la lèvre annulaire 20 vient s'écraser sur le bord libre 10c du col 10.When the perforation and cutting means 16 are pressed in (right part in Figure 1), the transverse wall 15 abuts against the free edge 7a of the side wall forming a skirt 7, while the annular lip 20 is crushed on the free edge 10c of the neck 10.
