Description

La présente invention concerne une capsule de fermeture d'un contenant du type comportant des moyens de retenue clipables.The present invention relates to a closure cap of a container of the type comprising clipable retaining means.

De manière connue, ces moyens sont constitués d'une part par une zone périphérique proéminente réalisée sur la paroi interne d'un bord tombé ou jupe de la capsule, à proximité de son extrémité libre, et d'autre part par une collerette périphérique externe réalisée à proximité du bord supérieur du contenant.In known manner, these means are constituted firstly by a protruding peripheral zone formed on the inner wall of a fallen edge or skirt of the capsule, near its free end, and on the other hand by an external peripheral collar. near the top edge of the container.

Les parties de retenue sont complémentaires, et l'une et/ou l'autre sont déformables élastiquement pour coopérer entre elles de manière étanche en fermeture, tout en autorisant une action en ouverture manuelle aisée.The retaining portions are complementary, and one and / or the other are elastically deformable to cooperate with each other sealingly in closure, while allowing easy manual opening action.

Dans ce type de capsule, on prévoit habituellement de réaliser la zone périphérique proéminente interne de la capsule, constituant son moyen de retenue, sur la collerette du contenant, sous la forme d'une surépaisseur constituant un bossage annulaire disposé sur la paroi interne du bord tombé ou jupe.In this type of capsule, provision is usually made to make the internal prominent peripheral zone of the capsule, constituting its retaining means, on the collar of the container, in the form of an extra thickness constituting an annular boss disposed on the inner wall of the edge. fallen or skirt.

Selon une première phase de la démarche inventive, et dans un esprit de respect de l'environnement prônant la diminution des déchets en matière plastique, il a été recherché de diminuer le poids de cette matière, nécessaire à la fabrication d'une telle capsule.According to a first phase of the inventive step, and in a spirit of respect for the environment advocating the reduction of plastic waste, it has has been sought to reduce the weight of this material, necessary for the manufacture of such a capsule.

En effet, bien que paraissant à première vue insignifiant, une prise de conscience, suivie d'une estimation, a permis de découvrir que quelques grammes gagnés sur un produit distribué à plusieurs millions d'exemplaires représentaient une masse de matière énorme.Although, at first glance, seemingly insignificant, an awareness, followed by an estimate, made it possible to discover that a few grams earned on a product distributed to several millions of copies represented a huge mass of matter.

Ainsi, si l'on gagne par exemple un gramme de matière plastique, le gain sur un million de capsules fabriquées serait d'une tonne.Thus, if you gain for example a gram of plastic material, the gain on one million capsules manufactured would be one ton.

La présente invention a pour but de remédier aux inconvénients précités et d'atteindre ce type d'objectif.The present invention aims to overcome the aforementioned drawbacks and to achieve this type of objective.

A cet effet, elle concerne une capsule de fermeture d'un contenant comportant des moyens de retenue sur celui-ci, clipables, constitués d'une part par une zone périphérique proéminente réalisée sur la paroi interne d'un bord tombé ou jupe de la capsule, à proximité de son extrémité libre, et d'autre part par une collerette périphérique externe réalisée à proximité du bord supérieur du contenant, les parties de retenue étant complémentaires, et l'une et/ou l'autre étant déformables élastiquement pour coopérer entre elles de manière étanche en fermeture, tout en autorisant une action en ouverture manuelle aisée, caractérisée en ce que la zone périphérique interne de la capsule est constituée par une déformation permanente vers l'intérieur, réalisée sur le bord tombé périphérique de celle-ci, selon un profil déterminé, d'épaisseur sensiblement constante.For this purpose, it relates to a closure cap of a container comprising retaining means thereon, clipable, formed firstly by a prominent peripheral zone formed on the inner wall of a fallen edge or skirt of the capsule, near its free end, and secondly by an outer peripheral flange made near the upper edge of the container, the retaining portions being complementary, and one and / or the other being elastically deformable to cooperate between them sealingly closing, while allowing easy manual opening action, characterized in that the inner peripheral zone of the capsule is constituted by a deformation permanent inward, made on the peripheral edge of the latter, according to a determined profile, of substantially constant thickness.

Les essais ont démontré que, selon l'invention, jusqu'à trois grammes de matière plastique pouvaient être gagnés sur une capsule de 100 mm de diamètre, de 6 mm de haut et d'une épaisseur moyenne de 0,35 mm ± 0,15 mm.The tests have shown that, according to the invention, up to three grams of plastic material can be gained on a capsule 100 mm in diameter, 6 mm high and with an average thickness of 0.35 mm ± 0, 15 mm.

Autrement dit, pour cent millions de capsules fabriquées, nombre tout à fait réaliste dans ce type de produit, on peut estimer que ce sont trois cent tonnes de matière économisées.In other words, for 100 million manufactured capsules, a number quite realistic in this type of product, we can estimate that it is three hundred tonnes of material saved.

L'invention concerne également les caractéristiques qui ressortiront au cours de la description qui va suivre, et qui devront être considérées isolément ou selon toutes leurs combinaisons techniques possibles.The invention also relates to the features which will emerge during the following description, which should be considered in isolation or in all their possible technical combinations.

Cette description donnée à titre d'exemple non limitatif, fera mieux comprendre comment l'invention peut être réalisée en référence aux dessins annexés sur lesquels:

  • La figure 1 est une vue en perspective de dessus d'une capsule allégée selon l'invention.
  • La figure 2 est une vue en perspective de dessous d'une capsule allégée selon l'invention.

  • La figure 6 est une section partielle à échelle agrandie du détail A de la figure 5.
  • La figure 7 est une vue partielle en coupe à échelle agrandie selon la ligne VII-VII de la figure 3.
This description given by way of nonlimiting example, will better understand how the invention can be made with reference to the accompanying drawings in which:
  • The figure 1 is a perspective view from above of a lightened capsule according to the invention.
  • The figure 2 is a perspective view from below of a lightened capsule according to the invention.
  • The figure 3 is a plan view from above of a lightened capsule according to the invention.
  • The figure 4 is a plan view from below of a lightened capsule according to the invention.
  • The figure 5 is a cross section along line VV of the figure 3 .
  • The figure 6 is an enlarged partial section of detail A of the figure 5 .
  • The figure 7 is a partial view in section on an enlarged scale along the line VII-VII of the figure 3 .

La capsule 1 globalement désignée sur les figures est destinée à la fermeture d'un contenant 2.The capsule 1 generally designated in the figures is intended for closing a container 2.

Elle comporte, de manière connue, des moyens de retenue sur ce dernier, clipables, constitués d'une part par une zone périphérique proéminente 5 réalisée sur la paroi interne 3 d'un bord tombé ou jupe 4 de la capsule 1, à proximité de son extrémité libre, et d'autre part par une collerette périphérique externe 6 réalisée à proximité du bord périphérique du contenant 2.It comprises, in known manner, retaining means on the latter, clipable, consisting on the one hand by a protruding peripheral zone 5 formed on the inner wall 3 of a fallen edge or skirt 4 of the capsule 1, close to its free end, and secondly by an outer peripheral flange 6 made near the peripheral edge of the container 2.

Les parties 5 et 6 de retenue sont complémentaires. L'une des deux, voire les deux, sont déformables élastiquement pour coopérer entre elles de manière étanche, en fermeture, tout en autorisant une action en ouverture manuelle aisée.The parts 5 and 6 retaining are complementary. One or both of the two are elastically deformable to cooperate with each other in a sealed manner, while closing, while allowing an action in easy manual opening.

Selon l'invention, et d'une manière générale, la zone périphérique interne 5 de la capsule 1 est constituée par une déformation permanente vers l'intérieur, réalisée sur le bord tombé périphérique 4 de celle-ci, selon un profil déterminé, d'épaisseur constante.According to the invention, and in a general manner, the inner peripheral zone 5 of the capsule 1 is constituted by a permanent deformation towards the inside, made on the peripheral fallen edge 4 of this, according to a determined profile, of constant thickness.

Plus précisément, le profil de la déformation 5 du bord tombé ou jupe 4 constituant le moyen de retenue de ladite capsule 1 est obtenu à partir d'une gorge 7, annulaire, réalisée sur la périphérie externe inférieure dudit bord tombé 4, pour former un becquet périphérique 8 dirigé vers l'intérieur, d'épaisseur sensiblement constante et de dimensions et de formes aptes à coopérer en serrage élastique avec la collerette 6 externe du contenant 2.More specifically, the profile of the deformation 5 of the dropped edge or skirt 4 constituting the retaining means of said capsule 1 is obtained from a groove 7, annular, made on the lower outer periphery of said dropped edge 4, to form a peripheral spoiler 8 directed inwards, of substantially constant thickness and of dimensions and shapes adapted to cooperate in elastic clamping with the outer collar 6 of the container 2.

Selon le présent exemple de réalisation, la section du becquet 8 est formée par la partie inférieure d'un S dont la demi branche centrale 8a est dirigée vers l'intérieur, et son retour inférieur 8b vers l'extérieur, l'extrémité 8c de celui-ci s'inscrivant périphériquement, au plus, dans le volume engendré par la capsule 1.According to the present embodiment, the section of the spoiler 8 is formed by the lower part of an S whose central half leg 8a is directed inwards, and its lower return 8b outwards, the end 8c of this one registering peripherally, at most, in the volume generated by the capsule 1.

Ladite extrémité 8c est avantageusement arrondie afin d'éviter toute agressivité envers l'usager.Said end 8c is advantageously rounded to avoid any aggressiveness towards the user.

Selon une variante de réalisation non représentée, le bord tombé ou jupe périphérique 4 forme une dépouille négative par rapport au plan supérieur 10 de la capsule 1.According to an alternative embodiment not shown, the falling edge or peripheral skirt 4 forms a negative draft relative to the upper plane 10 of the capsule 1.

Selon ce dernier cas, l'angle de la dépouille négative du bord tombé 4 est préférentiellement compris entre 2 et 5°.According to the latter case, the angle of the negative draft of the falling edge 4 is preferably between 2 and 5 °.

Ceci présente l'avantage que ledit bord tombé 4 puisse être contenu dans le volume engendré par la capsule 1, tout en augmentant le diamètre de la zone d'extrémité constituant le retour inférieur du demi S, selon la section du becquet du bord tombé, en fait une zone de préhension devenant ainsi plus confortable.This has the advantage that said dropped edge 4 can be contained in the volume generated by the capsule 1, while increasing the diameter of the end zone constituting the lower return of the half S, according to the section of the spoiler of the fallen edge, in fact a gripping area thus becoming more comfortable.

Avantageusement, la capsule 1 est réalisée en matière plastique la rendant déformable élastiquement, pour se prêter au passage de la collerette 6 du contenant 2, puis à se positionner dessous, pour une fermeture complète étanche (voir figure 7).Advantageously, the capsule 1 is made of plastic material rendering it elastically deformable, to lend itself to the passage of the flange 6 of the container 2, then to position itself below, for a complete waterproof closure (see figure 7 ).

Pour cela, le diamètre externe de la collerette 6 du contenant 1 est plus important que le diamètre interne du bord tombé 4 de la capsule 1, au niveau du becquet 8.For this, the outer diameter of the collar 6 of the container 1 is greater than the internal diameter of the fallen edge 4 of the capsule 1, at the spoiler 8.

Préférentiellement, la collerette 1 est obtenue par une opération de moulage-injection d'un polypropylène, ou encore d'un polyéthylène.Preferably, the flange 1 is obtained by an injection-molding operation of a polypropylene or a polyethylene.

On aurait pu imaginer obtenir une telle capsule avec les caractéristiques décrites ci-dessus, par thermoformage plutôt que par moulage-injection, mais un certain nombre de problèmes serait apparu, comme par exemple, dans le cas de la réalisation avec une contre-dépouille formée par le bord tombé, qui n'aurait pas été réalisable selon la technique de thermoformage, où toutes les lignes de fuite doivent être parallèles à l'axe.It would have been conceivable to obtain such a capsule with the characteristics described above, by thermoforming rather than by injection molding, but a certain number of problems would have appeared, as for example, in the case of the realization with an undercut formed by the fallen edge, which would not have been feasible by the thermoforming technique, where all the vanishing lines must be parallel to the axis.

De plus, l'épaisseur constante du bord tombé et de son becquet interne ne pourrait pas être obtenue du fait des problèmes d'étirement sur les parois verticales, liés à ce procédé, d'où une étanchéité aléatoire.In addition, the constant thickness of the fallen edge and its internal spoiler could not be obtained because of the problems of stretching on the vertical walls, related to this process, resulting in a random seal.

Enfin, une découpe de l'extrémité du becquet, constituant une zone de préhension, serait nécessaire, créant ainsi une opération supplémentaire et une perte de matière, alors que l'objectif est précisément le gain de matière pour les raisons initialement évoquées.Finally, a cutout of the end of the spoiler, constituting a gripping area, would be necessary, thus creating an additional operation and a loss of material, while the objective is precisely the material gain for the reasons initially mentioned.

De plus, une telle découpe génère une partie saillante agressive lors d'une manipulation par un consommateur.In addition, such cutting generates an aggressive protruding part during handling by a consumer.

Enfin, on peut noter sur les figures la présence de huit fines nervures de renforcement 9 (voir figures 4, 5 et 6) disposées à proximité du bord périphérique du plan supérieur 10 de la capsule 1, non réalisables telles que représentées par thermoformage, et qui ont un rôle de renforcement et/ou de guidage de la capsule par rapport au contenant, lors d'une dépose dite « à la volée », sur une ligne de conditionnement automatique.Finally, it can be noted in the figures the presence of eight thin reinforcing ribs 9 (see Figures 4, 5 and 6 ) disposed near the peripheral edge of the upper plane 10 of the capsule 1, not feasible as shown by thermoforming, and which have a role of reinforcing and / or guiding the capsule relative to the container, during a said deposit "On the fly", on an automatic packaging line.
