Description

Domaine de l'inventionField of the invention

La présente invention concerne les distributeurs de papier ou de tissu, en particulier dans le domaine de l'hygiène. Elle concerne plus précisément les distributeurs dans lesquels le papier ou le tissu forme un rouleau. Le rouleau étant lui-même fixé à un support.The present invention relates to paper or fabric dispensers, particularly in the field of hygiene. It relates more specifically to the dispensers in which the paper or fabric forms a roll. The roller itself being attached to a support.

Etat de la techniqueState of the art

Il existe des systèmes de distribution, dits « systèmes captifs » qui peuvent être utilisés uniquement avec un certain type de rouleau, afin d'assurer le fonctionnement optimal de l'appareil.There are dispensing systems, called "captive systems" that can be used only with a certain type of roll, to ensure optimal operation of the device.

Le rouleau comprend une quantité de papier ou tissu enroulée autour d'un élément tubulaire creux nommé «âme ».The roll comprises a quantity of paper or fabric wrapped around a hollow tubular element called "soul".

Le lien mécanique entre le rouleau et son support peut être réalisé au moyen d'un ou deux bouchons fixé(s) à chaque extrémité de l'âme, le bouchon étant solidaire ou non du support. Chaque bouchon est retenu dans l'âme par friction, avec ajout éventuel d'excroissances sur sa face extérieure, telles que dents, languettes flexibles ou ailettes.The mechanical connection between the roller and its support can be achieved by means of one or two plugs fixed at each end of the core, the plug being secured or not to the support. Each cap is retained in the core by friction, with possible addition of growths on its outer face, such as teeth, flexible tongues or fins.

Ce type de bouchon est p.ex. divulgué dans le brevet US 2 169 399 , la demande de brevet GB 2 297 311 , le brevet US 2 380 644 ou le brevet US 7 364 112 .This type of plug is eg disclosed in the patent US 2,169,399 , the patent application GB 2,297,311 , the patent US 2,380,644 or the patent US 7,364,112 .

Bien que ces mécanismes de retenue soient suffisants pour bloquer le mouvement relatif en rotation du bouchon par rapport à l'âme, ils n'évitent cependant pas le risque d'une séparation accidentelle ou volontaire de l'ensemble âme-bouchon. En effet, la géométrie et la disposition des excroissances précitées sont telles qu'une force relativement faible, dirigée vers l'extérieur de l'âme et parallèlement à son axe de rotation, peut séparer le bouchon de l'âme, privant de la sorte le système captif de fonctionner correctement.Although these retaining mechanisms are sufficient to block the relative rotational movement of the plug with respect to the core, they do not however avoid the risk of accidental or voluntary separation of the entire core-plug. Indeed, the geometry and arrangement of the aforementioned growths are such that a relatively small force, directed towards the outside of the core and parallel to its axis of rotation, can separate the plug of the soul, thus depriving the captive system to work properly.

Il existe donc un besoin de remédier aux problèmes précités.There is therefore a need to remedy the aforementioned problems.

Description générale de l'inventionGeneral description of the invention

Un des buts de la présente invention vise à fortement réduire, voire supprimer, le risque d'une séparation accidentelle ou volontaire de l'ensemble âme-bouchon.One of the aims of the present invention is to greatly reduce or eliminate the risk of an accidental or voluntary separation of the entire core-plug.

A cet effet, l'invention concerne un nouveau type de bouchon de forme sensiblement cylindrique, qui se caractérise par le fait que sa surface latérale comprend un relief de type harpon, orienté de manière à empêcher une séparation de l'ensemble âme-bouchon.To this end, the invention relates to a new type of substantially cylindrical plug, which is characterized in that its side surface comprises a harpoon type relief, oriented so as to prevent separation of the entire core-plug.

Dans le présent document, par « relief de type harpon » on entend une structure qui oeuvre au maintien du bouchon dans l'âme et qui a également pour effet d'augmenter la résistance au retrait lorsqu'une force de séparation est exercée sur le bouchon, à l'image d'un harpon que l'on tenterait de retirer d'une proie.In the present document, the term "harpoon relief" means a structure which works to maintain the plug in the core and which also has the effect of increasing the resistance to shrinkage when a separating force is exerted on the plug. , like a harpoon that one would try to remove from prey.

L'invention sera mieux comprise ci-dessous au moyen d'exemples illustrés par des figures.The invention will be better understood below by means of examples illustrated by figures.

Le système illustré sur la figure 1 présente diverses vues d'un premier type de bouchon selon l'invention.The system illustrated on the figure 1 presents various views of a first type of plug according to the invention.

Le système illustré sur la figure 2 présente diverses vues d'un deuxième type de bouchon selon l'invention.The system illustrated on the figure 2 presents various views of a second type of plug according to the invention.

Le bouchon illustré sur les figures 1 et 2 a une forme sensiblement cylindrique.
Son diamètre externe est sensiblement égal, voire légèrement inférieur, au diamètre interne de l'âme. Une fois le bouchon mis en place dans l'âme, sa face latérale externe exerce une force radiale sur la paroi interne de l'âme de manière que le bouchon soit retenu par friction à l'intérieur de celle-ci.
La face latérale du bouchon se présente sous la forme d'une couronne constituée de languettes de support 1 et de languettes de retenue 2 disposées en alternance le long de sa circonférence. Les deux types de languette sont élastiques selon une direction radiale, c'est-à-dire perpendiculaire à l'axe principal de l'âme.The cap shown on the figures 1 and 2 has a substantially cylindrical shape.
Its outer diameter is substantially equal to or even slightly less than the internal diameter of the core. Once the plug is placed in the core, its outer lateral face exerts a radial force on the inner wall of the core so that the cap is frictionally retained within it.
The lateral face of the plug is in the form of a ring consisting of support tongues 1 and retaining tongues 2 arranged alternately along its circumference. Both types of tab are elastic in a radial direction, that is to say perpendicular to the main axis of the soul.

Les languettes de support 1 ont pour fonction principale d'assurer un bon positionnement du bouchon dans l'âme et de minimiser le déplacement radial relatif de l'ensemble âme-bouchon.The main purpose of the support tongues 1 is to ensure proper positioning of the plug in the core and to minimize the relative radial displacement of the core-plug assembly.

L'extrémité libre d'une languette de support 1 est formée d'un bord orienté perpendiculairement par rapport à la direction principale de la languette de support 1. Ce bord constitue un moyen de limitation de l'enfoncement du bouchon dans l'âme. Les languettes de retenue 2 ont pour fonction principale d'éviter une séparation accidentelle ou volontaire de l'ensemble âme-bouchon. Les languettes de retenue 2 forment un relief de type harpon tel que décrit précédemment.The free end of a support tongue 1 is formed of an edge oriented perpendicular to the main direction of the support tongue 1. This edge is a means of limiting the depression of the plug in the core. The main purpose of the retaining tabs 2 is to prevent accidental or deliberate separation of the core-plug assembly. The retaining tabs 2 form a harpoon relief as described above.

L'extrémité libre des languettes de retenue 2 peut être formée d'un bord simple, suffisamment acéré pour pénétrer dans la paroi de l'âme (voir figure 1). Alternativement (voir figure 2), l'extrémité libre peut comporter 2 pointes, orientées perpendiculairement par rapport à l'axe de symétrie principale du bouchon.The free end of the retaining tongues 2 may be formed of a single edge, sufficiently sharp to penetrate the wall of the soul (see figure 1 ). Alternatively (see figure 2 ), the free end may comprise two points, oriented perpendicularly to the main axis of symmetry of the plug.

Les languettes de support 1 et/ou de retenue 2 peuvent être conçues de manière à ce que l'application d'une force de séparation importante peut casser les languettes 1,2, rendant de la sorte le bouchon inutilisable.The support tongues 1 and / or retaining 2 may be designed so that the application of a large separating force can break the tabs 1,2, thereby rendering the cap unusable.

A relever enfin que dans le bouchon de la figure 2 la zone de pliage des languettes de retenue 2 se situe à l'intérieur de la circonférence définie par les languettes de support 1, ce qui permet d'assurer un tenue optimale du bouchon dans l'âme.To finally note that in the cap of the figure 2 the folding zone of the retaining tongues 2 is located inside the circumference defined by the support tongues 1, which makes it possible to ensure optimal holding of the plug in the core.

Il va sans dire que l'invention ne se limite pas aux exemples illustrés.It goes without saying that the invention is not limited to the illustrated examples.
