Description

La présente invention a trait à un élément de bouchage, du type bouchon fileté, apte à être disposé de manière amovible sur un récipient, sous forme notamment d'un pot en verre, d'une bouteille, d'un flacon, ou autre forme encore. L'invention est tout particulièrement adaptée au bouchage des pots en verre tels que ceux utilisés pour le conditionnement de crèmes de soin.The present invention relates to a plugging element, of the threaded plug type, suitable for being removably placed on a container, in the form including a glass jar, bottle, flask, or other form again. The invention is particularly suitable for plugging pots in glass such as those used for packaging skincare creams.

Dans le domaine de la cosmétique, et en particulier dans le domaine des crèmes de soin, il est relativement répandu d'utiliser des pots en verre. Ces pots sont généralement fermés au moyen d'un couvercle en plastique, comportant un filetage apte à coopérer avec un filetage correspondant prévu sur une surface externe du pot, au voisinage d'une ouverture délimitée par un bord libre.In the field of cosmetics, and in particular in the field of skincare creams, it is relatively common to use glass jars. These jars are usually closed with a plastic cover, comprising a thread capable of cooperating with a corresponding thread provided on an external surface of the pot, in the vicinity of an opening delimited by a free edge.

Un des problèmes rencontrés dans ce type de conditionnement tient au jeu important existant entre le pot et sa capsule plastique, lequel jeu tient essentiellement aux tolérances de fabrication du filetage en verre, qui sont très élevées. Un tel jeu entraíne des problèmes d'étanchéité et de conservation de la crème contenue dans le pot. En outre, il n'est pas très bien perçu par les consommateurs.One of the problems encountered in this type of conditioning is due to the game important existing between the pot and its plastic capsule, which game holds essentially the manufacturing tolerances for glass threads, which are very high. Such a game leads to problems of tightness and conservation of the cream contained in the jar. Furthermore, it is not very well received by consumers.

Aussi, est-ce un des objets de l'invention que de fournir un élément de bouchage résolvant en tout ou partie les problèmes discutés ci-avant en référence aux dispositifs conventionnels.It is therefore one of the objects of the invention to provide an element of capping resolving all or part of the problems discussed above in reference to conventional devices.

C'est un autre objet de l'invention que de fournir un élément de bouchage, notamment pour un récipient en verre, et apte à pallier les tolérances de fabrication importantes du verre.It is another object of the invention to provide a closure element, especially for a glass container, and able to overcome the tolerances of important glass manufacturing.

C'est encore un autre objet de l'invention que de fournir un élément de bouchage simple et économique à fabriquer, notamment par moulage. It is yet another object of the invention to provide an element of simple and economical closure to manufacture, in particular by molding.

D'autres objets apparaítront de manière détaillée dans la description qui suit.Other objects will appear in detail in the description which follows.

Selon l'invention, ces objets sont atteints en réalisant un élément de bouchage comportant un premier filetage apte à coopérer avec un second filetage, formé par un récipient destiné à recevoir ledit élément de bouchage, caractérisé en ce qu'il comprend des moyens élastiquement déformables aptes, en position d'engagement desdits premier et second filetages, à maintenir en appui élastique ledit élément de bouchage sur ledit récipient selon au moins une direction orientée radialement par rapport audit élément de bouchage, de manière à améliorer la tenue de l'élément de bouchage sur le récipient. Ainsi, la présence de ces moyens élastiquement déformables permet de compenser les tolérances importantes dans la réalisation du filetage porté par le récipient, en particulier lorsqu'il s'agit d'un récipient en verre.According to the invention, these objects are achieved by producing a plugging element comprising a first thread capable of cooperating with a second thread, formed by a container intended to receive said plugging element, characterized in that it comprises elastically deformable means capable, in position of engagement of said first and second threads, to be supported elastic said plugging member on said container according to at least one direction oriented radially with respect to said closure element, so as to improve the resistance of the closure element on the container. So the presence of these elastically deformable means makes it possible to compensate for the large tolerances in the production of the thread carried by the container, in especially when it is a glass container.

Avantageusement, lesdits moyens élastiquement déformables sont aptes en position d'engagement desdits premier et second filetages, à maintenir en appui élastique au moins une portion du premier filetage sur au moins une portion correspondante du second filetage. La présence de ces moyens élastiquement déformables réalise un "freinage" du filetage lors du vissage/dévissage de l'élément de bouchage. En d'autres termes, on peut ainsi obtenir un jeu fonctionnel nul ou quasiment nul améliorant ainsi de façon substantielle la qualité du conditionnement.Advantageously, said elastically deformable means are suitable for position of engagement of said first and second threads, to be maintained in elastic support at least a portion of the first thread on at least one corresponding portion of the second thread. The presence of these means elastically deformable performs "braking" of the thread during screwing / unscrewing the plugging element. In other words, we can thus obtain a zero or almost zero functional clearance thus improving in a way the quality of the packaging.

Selon un mode de réalisation particulier, ledit élément de bouchage comporte une jupe latérale portant ledit premier filetage, lesdits moyens élastiquement déformables étant constitués d'au moins une portion élastiquement déformable de ladite jupe, et dont le rayon de courbure au repos est différent du rayon de courbure du reste de la jupe. Dans une telle configuration, le premier filetage est de préférence réalisé sur la paroi interne de la jupe latérale, de manière à pouvoir le mettre en engagement avec le second filetage porté par la paroi externe d'un col formé par le récipient. According to a particular embodiment, said closure element comprises a side skirt carrying said first thread, said means elastically deformable consisting of at least one elastically deformable portion of said skirt, and whose radius of curvature at rest is different from the radius of curvature of the rest of the skirt. In such a configuration, the first thread is preferably made on the inner wall of the side skirt, so that ability to engage with second thread carried by wall external of a neck formed by the container.

De préférence, lesdits moyens élastiquement déformables sont constitués d'au moins un "méplat" formé par ladite jupe. Un tel méplat peut, dans le cas d'un élément de bouchage obtenu de moulage d'un matériau thermoplastique, être obtenu en appliquant une déformation à la jupe latérale, à sa sortie du moule, et avant que la matière ne soit complètement refroidie. Selon une alternative avantageuse, le méplat est également obtenu directement de moulage, en conférant au moule la forme appropriée.Preferably, said elastically deformable means consist of at least minus a "flat" formed by said skirt. Such a flat may, in the case of a closure element obtained by molding a thermoplastic material, being obtained by applying a deformation to the side skirt, at its exit from the mold, and before the material is completely cooled. According to an alternative advantageous, the flat is also obtained directly from molding, in giving the mold the appropriate shape.

De préférence, l'élément de bouchage comporte deux moyens élastiquement déformables diamétralement opposés. En réalisant une telle symétrie, on améliore la tenue de l'élément de bouchage sur le récipient, et en particulier, un meilleur centrage de l'élément de bouchage sur le récipient. Le confort à l'ouverture et à la fermeture est amélioré de façon sensible.Preferably, the closure element comprises two elastically means deformable diametrically opposite. By achieving such symmetry, we improves the resistance of the closure element on the container, and in particular, a better centering of the closure element on the container. Comfort at opening and closing is significantly improved.

Selon un autre mode de réalisation spécifique, l'élément de bouchage comprend un plateau transversal dont un bord est replié à 90° de manière à former ladite jupe latérale portant ledit premier filetage. Une telle structure contribue à améliorer l'étanchéité à la fermeture.According to another specific embodiment, the closure element includes a transverse plate whose edge is folded at 90 ° so as to forming said side skirt carrying said first thread. Such a structure contributes to improving the seal upon closing.

De préférence, chacune desdites bandes élastiquement déformables est délimitée au moins en partie par une lumière ménagée dans ladite jupe latérale au voisinage du plateau transversal. Ainsi, à chaque lumière est associée une bande élastiquement déformable. Chacune des bandes élastiquement déformables s'étend sur toute la largeur angulaire de la lumière correspondante, et est délimitée d'une part par un bord de la lumière et d'autre part, par le bord libre de la jupe latérale, situé en regard de la lumière.Preferably, each of said elastically deformable strips is delimited at least in part by a light formed in said side skirt in the vicinity of the transverse plate. Thus, each light is associated with a elastically deformable strip. Each of the bands elastically deformable extends over the entire angular width of the light corresponding, and is delimited on the one hand by an edge of the light and on the other part, by the free edge of the side skirt, located opposite the light.

De préférence encore, ladite jupe latérale comprend au moins deux portions angulaires diamétralement opposées et exemptes de filetage. Une telle disposition permet un démoulage aisé de l'élément de bouchage, en autorisant un moule en trois parties, dont une partie centrale située en regard des portions exemptes de filetage et deux parties latérales. Le démoulage s'obtient en retirant en premier lieu la partie centrale puis en rapprochant l'une de l'autre les deux parties latérales, de manière à permettre le démoulage des parties filetées de l'élément de bouchage.More preferably, said side skirt comprises at least two portions diametrically opposite angular and free of thread. Such a arrangement allows easy release of the closure element, allowing a mold in three parts, including a central part located opposite the portions free of threads and two side parts. The release is obtained in first removing the central part and then bringing the two side parts, so as to allow the parts to be removed from the mold of the plugging element.

Selon un mode de réalisation particulièrement avantageux, l'élément de bouchage comprend deux lumières situées à l'extérieur des portions angulaires exemptes de filetage. Avantageusement, les deux lumières sont diamétralement opposées. Avantageusement encore, les deux lumières sont centrées sur un axe sensiblement perpendiculaire à un axe sur lequel sont centrées les deux portions exemptes de filetage. Le démoulage de ces deux lumières est permis lors du mouvement de rapprochement des deux parties latérales du moule.According to a particularly advantageous embodiment, the element of plugging includes two lights located outside the angular portions free of threads. Advantageously, the two lights are diametrically opposite. Advantageously again, the two lights are centered on an axis substantially perpendicular to an axis on which are centered the two thread-free portions. The release of these two lights is allowed when moving the two parts closer sides of the mold.

Dans le cas d'un élément de bouchage obtenu de moulage, il peut être formé d'un matériau thermoplastique, notamment un polyéthylène ou un polypropylène.In the case of a closure element obtained by molding, it can be formed of a thermoplastic material, in particular a polyethylene or a polypropylene.

L'élément de bouchage peut être revêtu d'un habillage extérieur dont la fonction est principalement esthétique, notamment en masquant les lumières réalisées dans la jupe latérale de l'élément de bouchage. En outre, l'habillage extérieur permet de renforcer la rigidité de la structure portant le filetage. Cet habillage autorise par ailleurs l'utilisation de matériaux dont l'esthétique est particulièrement adaptée à des domaines telle que la cosmétique. L'élément de bouchage peut être rendu solidaire de l'habillage extérieur par toute technique appropriée, notamment par collage, soudure, ou claquage.The plugging element can be coated with an external covering, the function is mainly aesthetic, in particular by hiding the lights made in the side skirt of the closure element. In addition, the dressing exterior makes it possible to reinforce the rigidity of the structure carrying the thread. This dressing also allows the use of materials whose aesthetics are particularly suitable for areas such as cosmetics. The element of clogging can be made integral with the exterior cladding by any technique appropriate, in particular by bonding, welding, or breakdown.

Selon un autre aspect de l'invention, on réalise également un récipient comprenant un élément de bouchage selon l'invention.According to another aspect of the invention, a container is also produced comprising a closure element according to the invention.

Avantageusement, ledit récipient est en verre. Il peut s'agir notamment d'un pot destiné au conditionnement d'une crème de soin. Advantageously, said container is made of glass. It can especially be a pot intended for the conditioning of a care cream.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions qui seront explicitées ci-après, à propos d'exemples de réalisation non limitatifs, décrits en référence aux figures annexées, parmi lesquelles :

  • la figure 1 représente une vue d'ensemble d'un récipient en verre équipé d'une élément de bouchage conforme à l'invention;
  • les figures 2A-2B représentent une vue détaillée de l'élément de bouchage utilisé pour le récipient de la figure 1; et
  • les figures 3A-3C représentent les principales étapes de moulage/démoulage d'un élément de bouchage tel que représenté aux figures 2A et 2B.
The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:
  • Figure 1 shows an overview of a glass container equipped with a closure element according to the invention;
  • Figures 2A-2B show a detailed view of the closure element used for the container of Figure 1; and
  • FIGS. 3A-3C represent the main stages of molding / demolding a plugging element as shown in FIGS. 2A and 2B.

Le récipient 1 représenté à la figure 1 comprend un corps 2 dont une extrémité est fermée par un fond 3 et dont l'autre extrémité se termine par un col 4 dont un bord libre 5 délimite une ouverture 6. La surface extérieure du col 4 présente un filetage 7 apte, comme on le verra plus en détail par la suite à coopérer avec un filetage correspondant (11, figure 2A) d'un élément de bouchage 10. Dans ce mode de réalisation, l'élément de bouchage 10 comprend une partie interne 12, disposée à l'intérieur d'un habillage extérieur 13. La partie 12 peut être montée à l'intérieur de l'habillage extérieur 13, par collage, soudure, ou claquage. La partie 12 comporte une paroi transversale 14 dont le bord est replié à 90° pour former une jupe latérale 15, sur la surface interne de laquelle est disposé le filetage 11. La jupe latérale comporte deux lumières 24, 25, diamétralement opposées, situées au voisinage de la zone de jonction entre la paroi transversale 14 et la jupe latérale 15, et dont on reparlera plus en détail par la suite.The container 1 shown in FIG. 1 comprises a body 2, one end of which is closed by a bottom 3 and the other end of which ends with a neck 4 whose a free edge 5 defines an opening 6. The outer surface of the neck 4 has a suitable thread 7, as will be seen in more detail below. cooperate with a corresponding thread (11, FIG. 2A) of an element of plugging 10. In this embodiment, the plugging element 10 includes an internal part 12, arranged inside an external covering 13. The part 12 can be mounted inside the external covering 13, by bonding, welding, or breakdown. Part 12 has a transverse wall 14 whose edge is folded at 90 ° to form a side skirt 15, on the surface internal of which is disposed the thread 11. The side skirt has two lights 24, 25, diametrically opposite, located in the vicinity of the junction between the transverse wall 14 and the side skirt 15, which will be discussed again in more detail later.

Les figures 2A et 2B auxquelles il est maintenant fait référence, illustrent de manière plus détaillée, la partie 12 de l'élément de bouchage 10. Ainsi que mentionné précédemment, cette partie 12 comprend un fond ou paroi transversale 14 dont le bord est replié à 90° pour former une jupe latérale 15. La surface interne de la jupe latérale 15 porte un filetage 11, formé de deux parties 20, 21, séparées par deux portions de jupe 22, 23, exemptes de tout filetage. Les deux portions 22, 23 sont diamétralement opposées, et centrées selon un axe X. La jupe latérale 15 présente également deux lumières 24, 25, traversant l'épaisseur de la jupe 15. Les deux lumières 24, 25 s'étendent parallèlement au plan du fond 14, et formées sensiblement à la jonction entre le fond 14 et la jupe latérale 15. Dans le mode de réalisation représenté, les deux lumières 24, 25 sont centrées sur un axe Y perpendiculaire à l'axe X. Ainsi, le bord supérieur 26 de la lumière 24 délimite avec la portion de bord libre 27 de la jupe située en regard de la lumière 24, une première portion élastiquement déformable 28. De même, le bord supérieur 29 de la lumière 25 délimite avec la portion de bord libre 30 de la jupe située en regard de la lumière 25, une seconde portion élastiquement déformable 31.Figures 2A and 2B, to which reference is now made, illustrate in more detail, part 12 of the plugging element 10. As well as mentioned previously, this part 12 includes a bottom or wall transverse 14 whose edge is folded at 90 ° to form a lateral skirt 15. The internal surface of the side skirt 15 carries a thread 11, formed of two parts 20, 21, separated by two skirt portions 22, 23, free of any thread. The two portions 22, 23 are diametrically opposite, and centered along an axis X. The side skirt 15 also has two openings 24, 25, crossing the thickness of the skirt 15. The two openings 24, 25 extend parallel to the plane of the bottom 14, and formed substantially at the junction between the bottom 14 and the side skirt 15. In the embodiment shown, the two lights 24, 25 are centered on a Y axis perpendicular to the X axis. Thus, the upper edge 26 of the light 24 delimits with the free edge portion 27 of the skirt located opposite the light 24, a first portion resiliently deformable 28. Similarly, the upper edge 29 of the light 25 delimits with the free edge portion 30 of the skirt located opposite the light 25, a second elastically deformable portion 31.

Comme représenté à la figure 2B, ces deux portions 28, 31 sont, après démoulage, et avant refroidissement complet de la matière, aplaties en utilisant un outil approprié, de manière à former deux méplats diamétralement opposés. L'aplatissement de ces deux portions 28, 31 peut résulter d'un déplacement δ de matière pouvant aller de quelques 10émes de mm à plusieurs mm. Après refroidissement complet, les deux portions 28, 31 sont figées dans la position représentée à la figure 2B. Ainsi, ces deux portions 28, 31 vont permettre un serrage élastique de la partie 12 de l'élément de bouchage sur le col du récipient 1, et ce, en deux zones diamétralement opposées, compensant ainsi pour tout jeu lié aux tolérances de fabrication du filetage en verre 7 du récipient 1. En d'autres termes, par ces deux portions aplaties 28, 31, on réalise deux portions de filetage à diamètre ou rayon de courbure différent du diamètre ou rayon de courbure du reste du filetage 11, permettant ainsi, lorsque la partie 12 est vissée sur le col 4 du récipient, de réaliser un vissage freiné, et, de ce fait, une bonne tenue de l'élément de bouchage 10 sur le récipient 1.As shown in FIG. 2B, these two portions 28, 31 are, after demolding, and before complete cooling of the material, flattened using a suitable tool, so as to form two diametrically opposite flats. The flattening of these two portions 28, 31 can result from a displacement δ of material which can range from a few 10 th of mm to several mm. After complete cooling, the two portions 28, 31 are frozen in the position shown in FIG. 2B. Thus, these two portions 28, 31 will allow an elastic tightening of the part 12 of the closure element on the neck of the container 1, and this, in two diametrically opposite zones, thus compensating for any play related to the manufacturing tolerances of the glass thread 7 of the container 1. In other words, by these two flattened portions 28, 31, two thread portions are produced with a diameter or radius of curvature different from the diameter or radius of curvature of the rest of the thread 11, thus allowing , when the part 12 is screwed onto the neck 4 of the container, to produce a braked screwing, and, therefore, good resistance of the plugging element 10 on the container 1.

Les figures 3A-3C illustrent un mode de réalisation du moule utilisé pour le réalisation de la portion 12 de l'élément de bouchage représenté aux figures 2A et 2B. Ainsi qu'il apparaít sur ces figures, le moule est constitué de trois parties : deux parties latérales 100, 101, et une partie centrale 102. Chacune des parties latérales présente les reliefs 103, 104, nécessaires d'une part, à la réalisation des portions 20, 21 du filetage 11, et d'autre part, à la réalisation des lumières 24, 25. La paroi latérale 105 de la partie centrale 102 est exempte de tout relief.FIGS. 3A-3C illustrate an embodiment of the mold used for the realization of the portion 12 of the closure element shown in FIGS. 2A and 2B. As it appears in these figures, the mold consists of three parts : two lateral parts 100, 101, and a central part 102. Each of the lateral parts presents the reliefs 103, 104, necessary on the one hand, for the production of portions 20, 21 of thread 11, and secondly, production of lights 24, 25. The side wall 105 of the central part 102 is free of all relief.

Ainsi, après moulage de la pièce 12 (correspondant à la position du moule telle que représentée à la figure 3A), la partie centrale 102 est escamotée de la manière représentée à la figure 3B. Ensuite, ainsi que représenté à la figure 3C, on rapproche entre elles les parties latérales 101, 103, de manière à dégager les reliefs 103, 104 des parties en creux correspondantes formées dans la pièce moulée, permettant ainsi le démoulage de la pièce 12. La pièce 12 à la sortie du moule, est conforme à ce qui est représenté à la figure 2A. Avant refroidissement de la matière, les deux portions 28 et 31 sont aplaties de la manière représentée à la figure 2B.Thus, after molding of the part 12 (corresponding to the position of the mold as as shown in FIG. 3A), the central part 102 is retracted from the as shown in Figure 3B. Then, as shown in the figure 3C, the side parts 101, 103 are brought together so as to release the reliefs 103, 104 from the corresponding hollow parts formed in the molded part, thus allowing the part 12 to be removed from the mold. 12 at the outlet of the mold, conforms to what is shown in Figure 2A. Before the material cools, the two portions 28 and 31 are flattened the manner shown in Figure 2B.

Selon une alternative avantageuse, la forme aplatie au niveau des deux bandes élastiquement déformables 28, 31, résulte directement du moulage, en conférant aux parties latérales 100 et 101 du moule, la forme aplatie correspondante. Ainsi, la pièce sort du moule, directement avec la forme requise.According to an advantageous alternative, the flattened shape at the level of the two elastically deformable bands 28, 31, results directly from molding, in giving the lateral parts 100 and 101 of the mold, the flattened shape corresponding. So the part comes out of the mold, directly with the shape required.

Dans la description détaillée qui précède, il a été fait référence à des modes de réalisation préférés de l'invention. Il est évident que des variantes peuvent y être apportées sans s'écarter de l'esprit de l'invention telle que revendiquée ci-après.In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. It is obvious that variants may exist there. be made without departing from the spirit of the invention as claimed below.
