Description

L'invention concerne un dispositif d'assemblage, pour assembler un capot sur un col de récipient.The invention relates to an assembly device for assembling a cover on a container neck.

On connait de nombreux capots de fermeture de récipient : il existe en réalité un nombre indéfinissable de formes de capots, appelés également bouchon ou capuchon.We know of many container closure covers: there are in reality an indefinable number of cover shapes, also called plugs or caps.

On comprendra par capot un ustensile qui permet d'assurer la fermeture étanche d'une ouverture d'un récipient, le bord de l'ouverture étant défini par le col du récipient. Le capot est l'ustensile qui assure la fermeture étanche de l'ouverture du récipient par fixation sur le col et / ou autour du col du récipient.By cover will be understood a utensil which makes it possible to ensure the watertight closure of an opening of a container, the edge of the opening being defined by the neck of the container. The cover is the utensil which ensures the watertight closure of the opening of the container by fixing on the neck and/or around the neck of the container.

Deux modes de fixation sont préférés dans l'industrie : la fixation par vissage et la fixation par clipsage.Two methods of fixing are preferred in the industry: fixing by screwing and fixing by clipping.

La fixation par vissage implique que le col du récipient et que l'intérieur du capot soient munis de filetage complémentaires.Fixing by screwing implies that the neck of the container and the inside of the cover are provided with complementary threads.

La fixation par clipsage nécessite de prévoir une bague saillante autour du col de récipient et un capot présentant un ergo interne saillant, le capot étant suffisamment souple pour autoriser sa déformation afin de permettre le passage de l'ergo d'un côté ou de l'autre de la bague saillante du col, pour assurer la fixation du capot ou sa désolidarisation.Fixing by clipping requires providing a protruding ring around the container neck and a cover having a protruding internal ergo, the cover being sufficiently flexible to allow its deformation in order to allow the passage of the ergo from one side or the other of the protruding ring of the neck, to ensure the fixing of the cover or its detachment.

Souvent la matière dans laquelle est réalisé le capot impose le système de fixation que sera mis en oeuvre pour l'utiliser : un capot réalisé en matière plastique pourra être équipé d'un filetage interne ou d'un ergot, permettant les deux systèmes de fixation. Un capot réalisé en métal sera plus facilement réalisé pour se fixer par vissage.Often the material from which the cover is made dictates the fixing system that will be implemented to use it: a cover made of plastic can be equipped with an internal thread or a lug, allowing both fixing systems . A cover made of metal will be more easily made to be fixed by screwing.

Un capot en verre est difficilement fixé sur le col d'un récipient : il est souvent remplacé par un bouchon en verre, dont une partie est insérée dans le goulot du récipient.A glass cover is difficult to attach to the neck of a container: it is often replaced by a glass stopper, part of which is inserted into the neck of the container.

En effet, il est difficile de créer des filetages internes dans des capots en verre.This is because it is difficult to create internal threads in glass covers.

Il existe des solutions suivant lesquelles un dispositif de fixation est fixé par collage dans le capot pour permettre soit sa fixation dans le goulot du récipient soit son vissage autour du col du récipient.There are solutions according to which a fixing device is fixed by gluing in the cover to allow either its fixing in the neck of the container or its screwing around the neck of the container.

Ces solutions ne sont pas satisfaisantes : en effet, les éléments de fixation qui sont fixés dans les capots se désolidarisent souvent, ce qui peut aboutir à ce que les récipients soient condamnés à rester fermés de façon étanche par les éléments de fixation solidarisés préalablement aux capots, rendant le contenu du récipient inaccessible.These solutions are not satisfactory: in fact, the fixing elements which are fixed in the covers often become detached, which can result in the containers being condemned to remain sealed tightly by the fixing elements secured beforehand to the covers, making the contents of the container inaccessible.

Si toutefois les éléments de fixations restent bien solidarisés, il en résulte que le capot n'est plus recyclable : en effet, il serait nécessaire de pouvoir désolidariser le capot et l'élément de fixation réalisé dans un autre matériau pour que chacun soit recyclable. Un dispositif d'assemblage est connu de US 2008/230540 A1 .If, however, the fixing elements remain firmly attached, the result is that the cover is no longer recyclable: in fact, it would be necessary to be able to separate the cover and the fixing element made of another material so that each is recyclable. An assembly device is known from US 2008/230540 A1 .

Il existe ainsi un besoin de proposer un système de fermeture étanche de récipients permettant la réalisation et l'utilisation de capots en verre, pour des raisons écologiques de recyclage de tels bouchons et éventuellement pour des besoins esthétiques de présentation de contenants.There is thus a need to propose a watertight container closure system allowing the production and use of glass covers, for ecological reasons for recycling such caps and possibly for aesthetic needs for presentation of containers.

L'invention vise à proposer un dispositif d'assemblage, qui permet d'assembler toute sorte de capot sur un col de récipient, et qui permet également de se désolidariser du capot pour permettre son recyclage et celui du capot. L'invention concerne à cet effet un dispositif d'assemblage, pour assembler un capot sur un col de récipient, le capot présentant une jupe latérale comportant une première extrémité libre de jupe et une seconde extrémité de jupe solidaire d'une paroi sommitale de capot, formant le fond de fermeture du capot, ladite jupe et ladite paroi sommitale délimitant un logement de capot, ledit dispositif d'assemblage étant remarquable en ce qu'il comporte :

  • un adaptateur de capot, présentant une cheminée, apte à être insérée dans le logement de capot, comportant un bord inférieur de cheminée bordé par une collerette à ailettes radiales remontantes, les ailettes formant un U avec le bord inférieur de la cheminée et étant orientées vers l'extérieur de la cheminée pour accueillir l'extrémité libre de la jupe dudit capot, l'une au moins desdites ailettes comportant une encoche présentant une forme coudée, dont une première partie d'encoche s'étend suivant une direction axiale de ladite cheminée et dont une seconde partie d'encoche s'étend suivant une direction radiale de ladite cheminée, et
  • une frette comportant une surface interne qui s'étend suivant un profil à symétrie de révolution autour d'un axe de frette, apte à venir encercler lesdites ailettes de la collerette dudit adaptateur de capot, ladite frette comportant une surface intérieure de frette comprenant au moins un ergot saillant, apte à être inséré dans ladite encoche de ladite au moins une ailette dudit adaptateur de capot.
The invention aims to propose an assembly device, which makes it possible to assemble any type of cover on a container neck, and which also makes it possible to separate from the cover to allow its recycling and that of the cover. To this end, the invention relates to an assembly device for assembling a cover on a container neck, the cover having a side skirt comprising a first free end of the skirt and a second end of the skirt secured to a top wall of the cover , forming the closing bottom of the hood, said skirt and said top wall delimiting a hood housing, said assembly device being remarkable in that it comprises:
  • a hood adapter, having a chimney, capable of being inserted into the hood housing, comprising a lower chimney edge bordered by a collar with rising radial fins, the fins forming a U with the lower edge of the chimney and being oriented towards the exterior of the chimney to accommodate the free end of the skirt of said hood, at least one of said fins comprising a notch having a bent shape, a first notch part of which extends in an axial direction of said chimney and of which a second notch part extends in a radial direction of said chimney, and
  • a hoop comprising an internal surface which extends along a profile with symmetry of revolution around a hoop axis, capable of encircling said fins of the flange of said cover adapter, said hoop comprising an interior hoop surface comprising at least a projecting lug, capable of being inserted into said notch of said at least one fin of said hood adapter.

On comprendra par « profil à symétrie de révolution » une forme cylindrique ou tronconique, ou toute autre forme autorisant une rotation de la frette autour d'un objet présentant une forme externe complémentaire avec également un profil à symétrie de révolution.By “rotationally symmetrical profile” we will understand a cylindrical or frustoconical shape, or any other shape allowing rotation of the hoop around an object having a complementary external shape also with a revolutionally symmetrical profile.

Ainsi réalisé, l'adaptateur du dispositif permet de fixer le capot sur un col de récipient car c'est l'adaptateur fixé au capot qui va permettre la fixation su capot sur le col. Cette fixation peut se faire de différentes façons : par exemple, la fixation peut se faire par pression radiale de la cheminée de l'adaptateur (écrasée entre la jupe du capot et la cheminée de l'adaptateur quand le capot équipé du dispositif ferme le col du récipient). La fixation peut également de faire en prévoyant, sur la surface interne de la cheminée, des moyens de fixation qui s'associent avec les moyens de fixation du col de récipient à fermer.Thus produced, the adapter of the device makes it possible to fix the cover on a container neck because it is the adapter fixed to the cover which will allow the fixing of the cover on the neck. This fixing can be done in different ways: for example, the fixing can be done by radial pressure of the adapter chimney (crushed between the skirt of the hood and the adapter chimney when the hood equipped with the device closes the collar container). Fixing can also be done by providing, on the internal surface of the chimney, fixing means which combine with the means for fixing the neck of the container to be closed.

Par ailleurs, la frette permet non seulement de fixer ensemble l'adaptateur et le capot par pression radiale, mais elle permet également de cacher les ailettes de l'adaptateur.Furthermore, the collar not only allows the adapter and the cover to be fixed together by radial pressure, but it also allows the fins of the adapter to be hidden.

Le dispositif conforme à l'invention peut également comprendre les caractéristiques suivantes, prises séparément ou en combinaison :

  • ladite cheminée dudit adaptateur peut comporter un bord supérieur de cheminée qui est solidaire d'une paroi de fermeture sommitale de cheminée. Ce mode de réalisation permet de masquer l'intérieur du récipient qui serait visible à travers un capot transparent. Il peut également être prévu un décor interne à un capot transparent en utilisant cette paroi de fermeture et la paroi extérieure de la cheminée,
  • ladite cheminée dudit adaptateur peut être de forme cylindrique ou en forme de tronc de cône. La forme en, tronc de cône peut favoriser l'introduction de la cheminée dans le logement de capot,
  • ladite cheminée peut comporter une surface intérieure de cheminée présentant un filetage. Cela permet un vissage du capot équipé du dispositif conforme à l'invention sur un col fileté de récipient,
  • lesdites ailettes de ladite collerette peuvent s'étendre sur une hauteur d'ailettes et ladite frette peut présenter une hauteur de frette qui est supérieure à ladite hauteur d'ailettes. Cette particularité permet de cacher les ailettes inesthétiques par la frette,
  • ledit bord inférieur de la cheminée de l'adaptateur, formant un U avec les ailettes remontantes pour accueillir l'extrémité libre de la jupe du capot, peut comporter au moins un pion saillant. Ce mode de réalisation permet de bloquer en rotation le capot par rapport à l'adaptateur, si capot comporte une encoche sur la tranche de l'extrémité libre de la jupe du capot, le pion saillant s'insérant dans l'encoche.
The device according to the invention may also include the following characteristics, taken separately or in combination:
  • said chimney of said adapter may include an upper chimney edge which is integral with a chimney top closing wall. This embodiment makes it possible to hide the interior of the container which would be visible through a transparent cover. An internal decoration can also be provided for a transparent cover using this closing wall and the exterior wall of the chimney,
  • said chimney of said adapter can be cylindrical in shape or in the shape of a truncated cone. The truncated cone shape can facilitate the introduction of the chimney into the hood housing,
  • said chimney may include an interior chimney surface having a thread. This allows the cover equipped with the device according to the invention to be screwed onto a threaded container neck,
  • said fins of said flange can extend over a fin height and said hoop can have a hoop height which is greater than said fin height. This feature allows the unsightly fins to be hidden by the hoop,
  • said lower edge of the adapter chimney, forming a U with the rising fins to accommodate the free end of the hood skirt, can have at least one protruding pawn. This embodiment makes it possible to lock the cover in rotation relative to the adapter, if the cover has a notch on the edge of the free end of the skirt of the cover, the protruding pin inserting into the notch.

L'invention concerne également un ensemble comportant un capot et un dispositif d'assemblage tel que défini ci-dessus.The invention also relates to an assembly comprising a cover and an assembly device as defined above.

Conformément à l'invention, le capot peut être réalisé en verre.According to the invention, the cover can be made of glass.

Par ailleurs, avantageusement, l'extrémité libre de la jupe du capot peut comporter au moins une encoche apte à accueillir ledit au moins un pion saillant de l'adaptateur, comme il a été présenté ci avant.Furthermore, advantageously, the free end of the skirt of the cover can include at least one notch capable of accommodating said at least one protruding pin of the adapter, as has been presented above.

L'ensemble conforme à l'invention peut également comprendre un récipient présentant un col de récipient sur lequel est fixé ledit capot équipé dudit dispositif d'assemblage.The assembly according to the invention may also include a container having a container neck on which said cover equipped with said assembly device is fixed.

Les figures 1 à 4 concerne un premier mode de réalisation de l'invention.THE figures 1 to 4 relates to a first embodiment of the invention.

La figure 1 montre un récipient 1 en verre, réalisé par un flacon présentant une paroi latérale 10 de forme cylindrique, un fond 11 et un col 12 de flacon par lequel un produit peut être introduit dans le flacon et par lequel un produit contenu dans le flacon peut être extrait ou délivré.There figure 1 shows a glass container 1, made by a bottle having a side wall 10 of cylindrical shape, a bottom 11 and a neck 12 of bottle by by which a product can be introduced into the bottle and by which a product contained in the bottle can be extracted or delivered.

Dans le cadre de cet exemple, le col 12 du flacon est un col de type FEA, c'est-à-dire un col présentant un bourrelet de sertissage.In the context of this example, the neck 12 of the bottle is an FEA type neck, that is to say a neck having a crimping bead.

Une pompe de délivrance 2 est fixée sur ce col 12 par sertissage : elle permet la délivrance d'un produit contenu dans le récipient (ou flacon) 1 par prélèvement grâce à un tube (non illustré) plongeant dans le flacon jusqu'au fond 11.A delivery pump 2 is fixed to this neck 12 by crimping: it allows the delivery of a product contained in the container (or bottle) 1 by sampling using a tube (not illustrated) plunging into the bottle to the bottom 11 .

Le flacon / récipient 1 est fermé par un capot 3 équipé d'un dispositif d'assemblage 4 conforme à l'invention. La capot 3 est également appelé bouchon dans le cadre de ce mode de réalisation.The bottle/container 1 is closed by a cover 3 equipped with an assembly device 4 according to the invention. The cover 3 is also called a cap in the context of this embodiment.

Le capot 3 est réalisé en verre. Il pourrait également être réalisé dans tout autre matériau sans sortir du cadre de l'invention : bois, métal, matière plastique etc. Le capot 3 est illustré plus en détail sur la figure 2.Cover 3 is made of glass. It could also be made from any other material without departing from the scope of the invention: wood, metal, plastic, etc. Cover 3 is illustrated in more detail on the figure 2 .

Le capot 3 présente une jupe latérale 30, cylindrique dans le cadre de cet exemple, présentant plusieurs diamètres, qui s'étend entre une première extrémité libre de jupe 31, apte à venir se placer en face d'un épaulement 13 du flacon / récipient 1, et une seconde extrémité de jupe 32 qui est solidaire d'une paroi sommitale 33 du capot, fermant le capot.The cover 3 has a side skirt 30, cylindrical in the context of this example, having several diameters, which extends between a first free end of skirt 31, capable of being placed opposite a shoulder 13 of the bottle/container 1, and a second skirt end 32 which is secured to a top wall 33 of the cover, closing the cover.

La jupe latérale cylindrique 30 présente ainsi une première partie de jupe 34, présentant un diamètre sensiblement identique au diamètre du flacon /récipient 1, comme on peut le voir en particulier sur la figure 1.The cylindrical side skirt 30 thus has a first skirt part 34, having a diameter substantially identical to the diameter of the bottle/container 1, as can be seen in particular on the figure 1 .

La première partie de jupe 34 est contiguë à une seconde partie de jupe 35 de diamètre plus petit, formant un premier épaulement 36 avec la première partie de jupe 34.The first skirt part 34 is contiguous to a second skirt part 35 of smaller diameter, forming a first shoulder 36 with the first skirt part 34.

Une troisième partie de jupe 37 présente un diamètre plus petit encore que celui de la seconde partie de jupe 35. Une gorge 38 radiale est réalisée entre la seconde partie de jupe 35 et la troisième partie de jupe 37.A third skirt part 37 has a diameter even smaller than that of the second skirt part 35. A radial groove 38 is made between the second skirt part 35 and the third skirt part 37.

L'extrémité libre 31 de la jupe 30 présente deux encoches radiales 39 diamétralement opposées, dont l'utilité sera exposée par la suite.The free end 31 of the skirt 30 has two diametrically opposed radial notches 39, the usefulness of which will be explained subsequently.

La jupe 30 présente une face interne cylindrique de diamètre constant et lisse. On voit ainsi que la face interne du capot ne présente aucun moyen d'accrochage sur le col 12 du flacon / récipient 1 et que le flacon / récipient 1 n'en comporte pas davantage.The skirt 30 has a cylindrical internal face of constant and smooth diameter. We can thus see that the internal face of the cover does not have any means of attachment to the neck 12 of the bottle/container 1 and that the bottle/container 1 does not have any more.

Le dispositif d'assemblage 4 conforme à l'invention, qui va maintenant être décrit, permet cet assemblage. Il permet également un désassemblage pour permettre un tri sélectif des différents éléments (capot, flacon ou récipient, dispositif d'assemblage).The assembly device 4 according to the invention, which will now be described, allows this assembly. It also allows disassembly for allow selective sorting of the different elements (cap, bottle or container, assembly device).

Le dispositif d'assemblage 4 conforme à l'invention comporte au moins deux éléments parmi lesquels un adaptateur 5 et une frette 6.The assembly device 4 according to the invention comprises at least two elements including an adapter 5 and a hoop 6.

L'adaptateur 5 est montré en figure 3.Adapter 5 is shown in Figure 3 .

Il comporte une cheminée 50 qui présente une forme de tronc de cône permettant de faciliter son insertion dans le capot 3. Il devra être compris que la cheminée 50 pourrait présenter une autre forme, par exemple une forme cylindrique, sans sortir du cadre de l'invention.It comprises a chimney 50 which has a truncated cone shape making it easier to insert it into the cover 3. It should be understood that the chimney 50 could have another shape, for example a cylindrical shape, without leaving the frame of the invention.

Le diamètre de la cheminée 50 est légèrement inférieur au diamètre interne du capot pour permettre son introduction.The diameter of the chimney 50 is slightly less than the internal diameter of the cover to allow its insertion.

Dans le cadre de cet exemple de réalisation, la cheminée 50 présente une extrémité sommitale qui est fermée : autrement dit, la cheminée est fermée à son extrémité sommitale par une paroi de fermeture supérieure 51, solidaire d'un bord supérieur 52 de la cheminée 50.In the context of this exemplary embodiment, the chimney 50 has a top end which is closed: in other words, the chimney is closed at its top end by an upper closing wall 51, secured to an upper edge 52 of the chimney 50 .

Ainsi, l'intérieur de la cheminée 50 n'est pas visible quand on regarde l'adaptateur par le dessus.Thus, the interior of the chimney 50 is not visible when looking at the adapter from above.

Cela permet, dans le cas où le capot 3 est réalisé en matière transparente, de ne pas voir l'intérieur du récipient et que le produit, contenu dans le flacon 1, ne vienne pas souiller le fond 33 (paroi sommitale) du capot 3.This allows, in the case where the cover 3 is made of transparent material, not to see the interior of the container and for the product, contained in the bottle 1, not to contaminate the bottom 33 (top wall) of the cover 3 .

Il devra toutefois être compris que la cheminée 50 pourrait être réalisée sans paroi de fermeture supérieure 51, sans sortir du cadre de l'invention.It should however be understood that the chimney 50 could be produced without an upper closing wall 51, without departing from the scope of the invention.

La cheminée 50 présente un bord inférieur 53 annulaire qui est bordé par une collerette 54 comprenant des ailettes radiales 55 remontantes vers l'extérieur de la cheminée.The chimney 50 has an annular lower edge 53 which is bordered by a collar 54 comprising radial fins 55 rising towards the outside of the chimney.

Les ailettes forment ainsi une forme en U avec la paroi de la cheminée 50, cette forme en U permettant d'accueillir l'extrémité libre 31 de la jupe 30 du capot 3 quand la cheminée 50 est insérée dans le capot 3.The fins thus form a U shape with the wall of the chimney 50, this U shape making it possible to accommodate the free end 31 of the skirt 30 of the cover 3 when the chimney 50 is inserted in the cover 3.

Pour éviter que le capot 3 ne tourne autour de la cheminée 50 de l'adaptateur 5 (ou que l'adaptateur 5 ne tourne à l'intérieur du capot 3), il peut être prévu de réaliser au moins un pion saillant dans la forme en U : ce pion saillant s'insère dans l'une ou l'autre des deux encoches 39 radiales de l'extrémité libre de la jupe 30, bloquant tout mouvement de rotation de l'adaptateur par rapport au capot dans un sens de rotation et dans l'autre.To prevent the cover 3 from rotating around the chimney 50 of the adapter 5 (or the adapter 5 from rotating inside the cover 3), it can be planned to make at least one protruding pin in the shape U-shaped: this protruding pin is inserted into one or the other of the two radial notches 39 of the free end of the skirt 30, blocking any rotational movement of the adapter relative to the cover in one direction of rotation and in the other.

Suivant d'autres modes de réalisation conformes à l'invention, il est prévu deux pions radiaux ou trois pions radiaux (voire éventuellement plus) suivant le format du capot et de l'adaptateur associé.According to other embodiments in accordance with the invention, two radial pins or three radial pins (or possibly more) are provided depending on the format of the cover and the associated adapter.

L'adaptateur 5 a pour fonction de maintenir le capot sur le col du flacon 1.The function of the adapter 5 is to hold the cover on the neck of the bottle 1.

Les ailettes 55 comportent, à leur extrémité libre, un bourrelet 90 orienté vers la cheminée 50.The fins 55 include, at their free end, a bead 90 oriented towards the chimney 50.

Dans le cadre de cet exemple, le maintien se fait par serrage radial.In the context of this example, the holding is done by radial tightening.

Pour permettre ce serrage, l'adaptateur doit rester ne place sur le capot également par serrage radial. Pour ce faire, l'adaptateur 5 doit être associé à la frette 6 évoquée ci-avant et visible notamment en figure 4.To allow this tightening, the adapter must remain in place on the cover also by radial tightening. To do this, the adapter 5 must be associated with the hoop 6 mentioned above and visible in particular in Figure 4 .

La frette 6 comporte un anneau cylindrique présentant une surface extérieure 60 et une surface intérieure 61.The hoop 6 comprises a cylindrical ring having an exterior surface 60 and an interior surface 61.

La surface intérieure 61 s'étend suivant un profil à symétrie de révolution autour de l'axe de la frette 6 : en effet, la surface intérieure 61 est cylindrique.The interior surface 61 extends along a rotationally symmetrical profile around the axis of the hoop 6: in fact, the interior surface 61 is cylindrical.

La surface extérieure 60 est, dans le cadre du présent exemple, également cylindrique. Elle pourrait toutefois présenter une forme différente, par exemple la frette pourrait présenter une forme extérieur quelconque, à facettes, de section polygonale etc. sans sortir du cadre de l'invention.The exterior surface 60 is, in the context of this example, also cylindrical. However, it could have a different shape, for example the hoop could have any external shape, faceted, with a polygonal section, etc. without departing from the scope of the invention.

Seule la forme intérieure de la frette est nécessairement à symétrie de révolution autour de son axe pour autoriser la rotation de la frette autour des ailettes de l'adaptateur.Only the internal shape of the hoop is necessarily rotationally symmetrical around its axis to allow the rotation of the hoop around the fins of the adapter.

Dans le cadre de l'exemple illustré, non limitatif, le diamètre de l'anneau cylindrique est sensiblement identique au diamètre extérieur de la paroi cylindrique 10 du flacon 1. De cette façon, la frette 6 se place dans le prolongement de la paroi 10 du flacon pour donner à l'ensemble un design élégant.In the context of the illustrated, non-limiting example, the diameter of the cylindrical ring is substantially identical to the external diameter of the cylindrical wall 10 of the bottle 1. In this way, the hoop 6 is placed in the extension of the wall 10 of the bottle to give the whole thing an elegant design.

Pour fixer la frette 6 autour de l'adaptateur 5, la surface intérieure 61 de l'anneau présente un ergot saillant 62.To fix the hoop 6 around the adapter 5, the interior surface 61 of the ring has a projecting lug 62.

Une encoche 56, présentant une forme coudée (en forme de L dans cet exemple de réalisation), est ménagée dans une ailette remontante 55 et est réalisée pour recevoir l'ergot saillant 62 solidaire de la frette 6.A notch 56, having a bent shape (L-shaped in this embodiment), is provided in a rising fin 55 and is made to receive the projecting lug 62 secured to the hoop 6.

L'encoche 56 présente ainsi deux parties d'encoche réalisant la forme coudée : une première partie d'encoche 57 est réalisée à travers l'ailette 55 et s'étend suivant une direction axiale (c'est-à-dire une direction parallèle à celle de l'axe de la cheminée 50), et une seconde partie d'encoche 58 est réalisée à travers l'ailette 55 et s'étend suivant une direction radiale (la seconde partie d'encoche forme un logement qui s'étend suivant un arc de cercle ayant pour centre celui de la cheminée 50).The notch 56 thus has two notch parts producing the bent shape: a first notch part 57 is made through the fin 55 and extends in an axial direction (that is to say a parallel direction to that of the axis of the chimney 50), and a second notch part 58 is made through the fin 55 and extends in a radial direction (the second notch part forms a housing which extends along an arc of a circle having as its center that of the chimney 50).

La première partie d'encoche 57 présente une ouverture d'entrée 59 située en partie basse de l'ailette remontante 55, à proximité du fond de la forme en U formée entre l'ailette 55 et la partie inférieure de la cheminée 50.The first notch part 57 has an inlet opening 59 located in the lower part of the rising fin 55, near the bottom of the U-shape formed between the fin 55 and the lower part of the chimney 50.

Pour permettre la fixation de la frette 6 sur l'adaptateur 5, l'ergot saillant 62 est inséré dans l'ouverture d'entrée 59 de la première partie d'encoche 57 en déplaçant la frette 6 suivant une direction axiale, dans un sens allant du bas vers le haut.To allow the fixing of the hoop 6 on the adapter 5, the projecting lug 62 is inserted into the entry opening 59 of the first notch part 57 by moving the hoop 6 in an axial direction, in one direction going from bottom to top.

Puis, la frette est maintenue en position sur l'adaptateur par rotation de la frette autour de l'adaptateur : grâce au mouvement de rotation, l'ergot saillant 62 se place dans la seconde partie d'encoche 58.Then, the hoop is held in position on the adapter by rotation of the hoop around the adapter: thanks to the rotational movement, the projecting lug 62 is placed in the second notch part 58.

Ainsi, la frette 6 est verrouillée en position autour des ailettes 55 de l'adaptateur 5, mis en place sur le capot 3.Thus, the hoop 6 is locked in position around the fins 55 of the adapter 5, placed on the cover 3.

Le capot 3 peut alors être positionné sur le col du flacon 1 : la cheminée 50 de l'adaptateur vient se fixer par friction autour un collier de sertissage 20 du col de la pompe 2 comme montré en figure 1.The cover 3 can then be positioned on the neck of the bottle 1: the chimney 50 of the adapter is fixed by friction around a crimping collar 20 of the neck of the pump 2 as shown in figure 1 .

Il devra être noté que la hauteur de la frette est supérieure à la hauteur des ailettes 55, pour que la frette recouvre entièrement les ailettes 55 quand elle les encercle.It should be noted that the height of the hoop is greater than the height of the fins 55, so that the hoop completely covers the fins 55 when it encircles them.

De plus, en position de fixation de la frette 6 avec l'adaptateur 5, le bord supérieur de la frette 6 vient en appui contre l'épaulement 36 de la jupe 30 du capot 3.Furthermore, in the fixing position of the hoop 6 with the adapter 5, the upper edge of the hoop 6 comes to rest against the shoulder 36 of the skirt 30 of the cover 3.

Enfin, quand la frette 6 est fixée à l'adaptateur 5, les bourrelets 90 des extrémités libres des ailettes 55 sont insérés dans la gorge 38 du capot 3.Finally, when the hoop 6 is fixed to the adapter 5, the beads 90 of the free ends of the fins 55 are inserted into the groove 38 of the cover 3.

Ainsi réalisé, le dispositif conforme à l'invention permet de fermer le flacon 1 avec un capot 3 qui ne présente aucun moyen de fixation particulier.Thus produced, the device according to the invention makes it possible to close the bottle 1 with a cover 3 which does not present any particular fixing means.

Cela permet de pouvoir fixer des capots réalisés dans des matériaux qui ne sont pas déformables ou qui sont difficilement usinables pour leur concevoir avec un moyen de fixation intégré (filetage ou autre).This makes it possible to fix covers made of materials which are not deformable or which are difficult to machine to design them with an integrated fixing means (thread or other).

Par exemple, dans le cadre du mode de réalisation montré sur les figures 1 à 4, le capot est réalisable en verre.For example, in the context of the embodiment shown on the figures 1 to 4 , the cover is made of glass.

L'adaptateur 5 permet alors de fixer le capot sur le collier de sertissage 20 : l'adaptateur 5, coiffé du capot 3, est engagé à force autour du collier 20.The adapter 5 then allows the cover to be fixed on the crimping collar 20: the adapter 5, covered with the cover 3, is forcefully engaged around the collar 20.

Le capot étant réalisé en verre transparent, l'adaptateur est visible à travers lui et peut servir d'élément décoratif ou de support d'informations ou de décoration.The cover being made of transparent glass, the adapter is visible through it and can serve as a decorative element or as a support for information or decoration.

Un autre mode de réalisation est illustré sur les figures 5 à 8 : ce mode de réalisation concerne un dispositif conforme à l'invention permettant de fixer un capot 7 sur un pot 8 (le pot 8 étant un récipient). Le capot 7 est alors usuellement appelé « couvercle ».Another embodiment is illustrated on the figures 5 to 8 : this embodiment concerns a device according to the invention making it possible to fix a cover 7 on a pot 8 (the pot 8 being a container). The cover 7 is then usually called “lid”.

Là encore, le capot 7 est en verre. Il pourrait être réalisé en bois, en plastique, en résine ou tout autre matériau sans sortir du cadre de l'invention.Here again, cover 7 is made of glass. It could be made of wood, plastic, resin or any other material without departing from the scope of the invention.

Les mêmes références ont été gardées pour l'adaptateur 5 et pour la frette 6, pour les éléments communs aux deux modes de réalisation.The same references have been kept for the adapter 5 and for the hoop 6, for the elements common to the two embodiments.

Le pot 8 comporte un récipient cylindrique, plus large que haut.Pot 8 includes a cylindrical container, wider than it is high.

Il devra être compris que le récipient pourrait présenter n'importe quelle forme.It should be understood that the container could have any shape.

Il comporte une paroi latérale 80 de forme cylindrique et un fond 81. Un bord supérieur libre 82 de la paroi latérale du pot 8 présente un filetage extérieur et délimite l'ouverture du pot 8. Un produit peut être introduit dans le pot 8 par cette ouverture et/ ou en être extrait ou délivré.It comprises a side wall 80 of cylindrical shape and a bottom 81. A free upper edge 82 of the side wall of the pot 8 has an external thread and delimits the opening of the pot 8. A product can be introduced into the pot 8 by this opening and/or being extracted or delivered.

Dans le cadre de l'exemple illustré, non limitatif, le capot 7 est également plus large que haut : il présente une jupe cylindrique 70, présentant plusieurs diamètres, qui s'étend entre une première extrémité de jupe libre 71, apte à venir se placer en face d'un épaulement 83 du pot 8, et une seconde extrémité de jupe 72 qui est solidaire d'une paroi sommitale 73 du capot 7, fermant le capot 7.In the context of the illustrated, non-limiting example, the cover 7 is also wider than it is high: it has a cylindrical skirt 70, having several diameters, which extends between a first end of the free skirt 71, able to come into place. place opposite a shoulder 83 of the pot 8, and a second end of skirt 72 which is integral with a top wall 73 of the cover 7, closing the cover 7.

La jupe cylindrique 70 présente ainsi une première partie de jupe 74, présentant un diamètre sensiblement identique au diamètre du pot 8, comme on peut le voir en particulier sur la figure 5.The cylindrical skirt 70 thus has a first skirt part 74, having a diameter substantially identical to the diameter of the pot 8, as can be seen in particular on the Figure 5 .

La première partie de jupe 74 est contiguë à une seconde partie de jupe 75 de diamètre plus petit, formant un premier épaulement 76 avec la première partie de jupe 74.The first skirt part 74 is contiguous to a second skirt part 75 of smaller diameter, forming a first shoulder 76 with the first skirt part 74.

Une troisième partie de jupe 77 présente un diamètre sensiblement égale ou égal à celui de la seconde partie de jupe 75. Une gorge 78 radiale est réalisée entre la seconde partie de jupe 75 et la troisième partie de jupe 77.A third skirt part 77 has a diameter substantially equal to or equal to that of the second skirt part 75. A radial groove 78 is made between the second skirt part 75 and the third skirt part 77.

L'extrémité libre 71 de la jupe 70 présente deux encoches radiales 79 diamétralement opposées.The free end 71 of the skirt 70 has two diametrically opposed radial notches 79.

La jupe 70 présente une face interne cylindrique de diamètre constant et lisse.The skirt 70 has a cylindrical internal face of constant and smooth diameter.

On ainsi que la face interne du capot 7 ne présente aucun moyen d'accrochage sur le bord fileté 82 du pot 8.It is thus that the internal face of the cover 7 does not present any means of attachment to the threaded edge 82 of the pot 8.

Le dispositif conforme à l'invention permet cette fixation grâce à un adaptateur 5', montré en figure 7 associé à une frette 6' montrée en figure 8.The device according to the invention allows this fixation thanks to a 5' adapter, shown in Figure 7 associated with a 6' fret shown in figure 8 .

La frette 6' est conçue comme la frette 6 : La frette 6' comporte un anneau cylindrique présentant une surface extérieure 60' et une surface intérieure 61', la surface intérieure 61' s'étendant suivant un profil à symétrie de révolution, sans angle, autorisant la rotation de la frette autour d'un autre objet présentant également une symétrie de révolution sans angle.The hoop 6' is designed like the hoop 6: The hoop 6' comprises a cylindrical ring having an exterior surface 60' and an interior surface 61', the interior surface 61' extending along a rotationally symmetrical profile, without angle , authorizing the rotation of the hoop around another object also having a symmetry of revolution without angle.

Le diamètre de l'anneau cylindrique de la frette 6' est sensiblement identique au diamètre extérieur de la paroi latérale cylindrique 80 du pot 8. De cette façon, la frette 6' se place dans le prolongement de la paroi 80 du pot 8.The diameter of the cylindrical ring of the hoop 6' is substantially identical to the external diameter of the cylindrical side wall 80 of the pot 8. In this way, the hoop 6' is placed in the extension of the wall 80 of the pot 8.

Pour fixer la frette 6' autour de l'adaptateur 5', la surface intérieure 61' de l'anneau présente un ergot saillant 62'.To fix the hoop 6' around the adapter 5', the interior surface 61' of the ring has a projecting lug 62'.

Comme pour l'adaptateur 5, l'adaptateur 5' comporte une cheminée 50' qui présente une forme cylindrique.As for the adapter 5, the adapter 5' includes a chimney 50' which has a cylindrical shape.

Le diamètre de la cheminée 50' est légèrement inférieur au diamètre interne du capot 7 pour permettre son introduction.The diameter of the chimney 50' is slightly less than the internal diameter of the cover 7 to allow its insertion.

La surface interne de la cheminée 50' présente un filetage qui permettra de fixer le capot, équipé du dispositif conforme à l'invention, par vissage autour du bord 82 du pot 8. Le filetage du bord 82 du pot 8 et celui de la surface interne de la cheminée 50' sont complémentaires.The internal surface of the chimney 50' has a thread which will allow the cover, equipped with the device according to the invention, to be fixed by screwing around the edge 82 of the pot 8. The thread of the edge 82 of the pot 8 and that of the surface internal of the 50' chimney are complementary.

Dans le cadre de cet exemple de réalisation, la cheminée 50' présente une extrémité sommitale qui est fermée : autrement dit, la cheminée est fermée à son extrémité sommitale par une paroi de fermeture supérieure 51', solidaire d'un bord supérieur 52' de la cheminée 50'.In the context of this exemplary embodiment, the chimney 50' has a top end which is closed: in other words, the chimney is closed at its top end by an upper closing wall 51', secured to an upper edge 52' of the 50' chimney.

Ainsi, l'intérieur de la cheminée 50' n'est pas visible quand on regarde l'adaptateur par le dessus.Thus, the interior of the 50' chimney is not visible when looking at the adapter from above.

Cela permet, dans le cas où le capot 7 est réalisé en matière transparente, de ne pas voir l'intérieur du récipient et que le produit, contenu dans le pot 8, ne vienne pas souiller le fond 73 (paroi sommitale) du capot 7.This allows, in the case where the cover 7 is made of transparent material, not to see the interior of the container and that the product, contained in the pot 8, does not soil the bottom 73 (top wall) of the cover 7 .

La cheminée 50' présente un bord inférieur 53' annulaire qui est bordé par une collerette 54' comprenant des ailettes radiales 55' remontantes vers l'extérieur de la cheminée.The chimney 50' has an annular lower edge 53' which is bordered by a flange 54' comprising radial fins 55' rising towards the outside of the chimney.

Les ailettes forment ainsi une forme en U avec la paroi de la cheminée 50', cette forme en U permettant d'accueillir l'extrémité libre 71 de la jupe 70 du capot 7 quand la cheminée 50' est insérée dans le capot 7.The fins thus form a U shape with the wall of the chimney 50', this U shape making it possible to accommodate the free end 71 of the skirt 70 of the cover 7 when the chimney 50' is inserted into the cover 7.

Les ailettes 55' comportent, à leur extrémité libre, un bourrelet 90' orienté vers la cheminée 50'.The fins 55' include, at their free end, a bead 90' oriented towards the chimney 50'.

Une des ailettes 55' comporte une encoche 56', présentant une forme coudée (en forme de L dans cet exemple de réalisation, comme pour l'autre capot 5), l'encoche 56' étant réalisée pour recevoir un ergot saillant 62' solidaire d'une frette 6' montrée en figure 8.One of the fins 55' has a notch 56', having a bent shape (L-shaped in this embodiment, as for the other cover 5), the notch 56' being made to receive an integral projecting lug 62' with a 6' fret shown in figure 8 .

L'encoche 56' présente ainsi deux parties d'encoche réalisant la forme coudée : une première partie d'encoche 57' est réalisée à travers l'ailette 55' (ou est formée dans l'épaisseur de l'ailette 55') et s'étend suivant une direction axiale (c'est-à-dire une direction parallèle à celle de l'axe de la cheminée 50'), et une seconde partie d'encoche 58' est réalisée à travers l'ailette 55' (ou est formée dans l'épaisseur de l'ailette 55') et forme un logement qui s'étend suivant un arc de cercle ayant pour centre celui de la cheminée 50.The notch 56' thus has two notch parts producing the bent shape: a first notch part 57' is made through the fin 55' (or is formed in the thickness of the fin 55') and extends in an axial direction (that is to say a direction parallel to that of the axis of the chimney 50'), and a second notch part 58' is made through the fin 55' ( or is formed in the thickness of the fin 55') and forms a housing which extends along an arc of a circle having as its center that of the chimney 50.

La première partie d'encoche 57' présente une ouverture d'entrée 59' située en partie basse de l'ailette remontante 55', à proximité du fond de la forme en U formée entre l'ailette 55' et la partie inférieure de la cheminée 50'.The first notch part 57' has an inlet opening 59' located in the lower part of the rising fin 55', near the bottom of the U-shape formed between the fin 55' and the lower part of the 50' fireplace.

Pour permettre la fixation de la frette 6' sur l'adaptateur 5', l'ergot saillant 62' est inséré dans l'ouverture d'entrée 59' de la première partie d'encoche 57' en déplaçant la frette 6' suivant une direction axiale, dans un sens allant du bas vers le haut.To allow the fixing of the hoop 6' on the adapter 5', the protruding lug 62' is inserted into the entry opening 59' of the first notch part 57' by moving the hoop 6' following a axial direction, in a direction going from bottom to top.

Puis, la frette est maintenue en position sur l'adaptateur par rotation de la frette autour de l'adaptateur : grâce au mouvement de rotation, l'ergot saillant 62' se place dans la seconde partie d'encoche 58'.Then, the hoop is held in position on the adapter by rotation of the hoop around the adapter: thanks to the rotational movement, the protruding lug 62' is placed in the second notch part 58'.

En position de fixation de la frette 6' avec l'adaptateur 5', le bord supérieur de la frette 6' vient en appui contre l'épaulement 76 de la jupe 70 du capot 7.In the fixing position of the hoop 6' with the adapter 5', the upper edge of the hoop 6' bears against the shoulder 76 of the skirt 70 of the cover 7.

De même, quand la frette 6' est fixée à l'adaptateur 5', les bourrelets 90' des extrémités libres des ailettes 55' sont insérés dans la gorge 78 du capot 7 (voir figure 5).Likewise, when the hoop 6' is fixed to the adapter 5', the beads 90' of the free ends of the fins 55' are inserted into the groove 78 of the cover 7 (see Figure 5 ).

Une fois que la frette 6' est associée à l'adaptateur 5', le capot 7 est équipé de moyens lui permettant de se fixer par vissage sur le bord 82 du pot 8 : en effet, la cheminée de l'adaptateur 5' forme alors une paroi interne dans le capot 7 équipée d'un filetage pouvant s'associer par vissage au filetage du bord 82.Once the hoop 6' is associated with the adapter 5', the cover 7 is equipped with means allowing it to be fixed by screwing onto the edge 82 of the pot 8: in fact, the chimney of the adapter 5' forms then an internal wall in the cover 7 equipped with a thread which can be associated by screwing with the thread of the edge 82.

On comprend de la description qui précède comment l'invention permet de fixer n'importe quel type de capot sur un col de récipient.We understand from the preceding description how the invention makes it possible to attach any type of cover to a container neck.

Il devra toutefois être entendu que l'invention n'est pas limitée aux deux exemples représentés et décrits précédemment : elle s'étend à la mise en oeuvre de tout moyen équivalent à condition qu'il soit contenu dans le domaine de protection tel que défini dans les revendications.It should however be understood that the invention is not limited to the two examples shown and described above: it extends to the implementation of any equivalent means provided that it is contained in the field of protection as defined in the claims.
