De manière non exclusive, l'invention trouve une application notamment dans la fourniture de produits de puériculture en permettant de proposer un récipient constituant un biberon très avantageux.Non-exclusively, the invention finds an application in particular in the supply of childcare products by making it possible to propose a container constituting a very advantageous bottle.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Il existe actuellement de nombreux récipients en matière souple, dont un avantage est d'éviter au récipient de se briser en cas de chute contrairement aux récipients en verre. Ils sont également légers et souvent d'une bonne maniabilité.There are currently many containers made of flexible material, one advantage of which is to prevent the container from breaking in the event of a fall, unlike glass containers. They are also lightweight and often easy to maneuver.

De tels récipients peuvent en particulier être configurés de sorte à remplir une fonction de biberon qui, comme on le sait, est un outil qui aide les nourrissons ou les jeunes enfants à ingérer des préparations liquides pour leur croissance.Such containers can in particular be configured so as to fulfill the function of a bottle which, as is known, is a tool which helps infants or young children to ingest liquid preparations for their growth.

Typiquement, un récipient de type biberon comprend un contenant creux capable de contenir une préparation liquide pour enfant ou nourrisson, un dispositif de fermeture amovible avec une tétine de succion et un système de couplage de la tétine au contenant.Typically, a bottle-type container comprises a hollow container capable of containing a liquid formula for a child or infant, a removable closure device with a suction teat and a system for coupling the teat to the container.

Il a déjà été imaginé de fabriquer tout ou partie d'un tel biberon en une silicone, ce qui offre comme avantage, outre ceux déjà indiqués ci-dessus, que le récipient présente un toucher agréable pouvant rappeler la texture de la peau afin de contribuer au développement émotionnel de l'utilisateur, et que le récipient soit hygiénique en limitant les risques de contamination de la préparation liquide.It has already been imagined to manufacture all or part of such a bottle out of a silicone, which offers the advantage, in addition to those already indicated above, that the container has a pleasant touch that can recall the texture of the skin in order to contribute the emotional development of the user, and that the container is hygienic by limiting the risks of contamination of the liquid preparation.

Dans la catégorie des biberons, il existe ceux dont le contenant et le système de couplage de la tétine au contenant sont intégralement fabriqués en silicone. De tels récipients sont toutefois peu pratiques à l'usage, la trop grande déformabilité de l'ensemble des pièces rendant certaines d'entre elles difficiles à manipuler et à assembler ensemble.In the category of baby bottles, there are those whose container and the system for coupling the teat to the container are entirely made of silicone. Such containers are however impractical to use, the excessive deformability of all the parts making some of them difficult to handle and to assemble together.

Il existe également des biberons dont seul le contenant est fabriqué en matière souple comme la silicone, le système de couplage étant volontairement fabriqué dans une matière rigide. Toutefois, de tels récipients sont particulièrement difficiles à fabriquer, en raison de la technique généralement utilisée de surmoulage du système de couplage par la silicone du contenant. En effet, le retrait du moule utilisé durant le surmoulage du contenant sur le système de couplage représente une réelle difficulté et limite considérablement les formes et les dimensions possibles de ces différentes pièces. En particulier, les dimensions du contenant doivent être maximales au niveau de l'ouverture supérieure, car à défaut il n'est pas possible de le démouler.There are also baby bottles in which only the container is made of a flexible material such as silicone, the coupling system being deliberately made of a rigid material. However, such containers are particularly difficult to manufacture, due to the generally used technique of overmolding the coupling system with the silicone of the container. Indeed, the shrinkage of the mold used during the overmolding of the container on the coupling system represents a real difficulty and considerably limits the possible shapes and dimensions of these various parts. In particular, the dimensions of the container must be maximum at the level of the upper opening, because otherwise it is not possible to unmold it.

A l'image des solutions décrites dans les documents TWM546953U et KR101263426 , il a déjà imaginé de prévoir un système de couplage comportant une première bague venant s'insérer dans un logement ménagé dans le récipient et venant se positionner autour d'un manchon délimité par le récipient et une deuxième bague venant en prise par vissage avec la première bague pour enserrer la tétine contre un épaulement supérieur du manchon.Like the solutions described in documents TWM546953U and KR101263426 , he has already imagined providing a coupling system comprising a first ring which is inserted into a housing provided in the container and which is positioned around a sleeve delimited by the container and a second ring which comes into screw engagement with the first ring to enclose the teat against an upper shoulder of the sleeve.

Toutefois, ces solutions ne donnent pas une entière satisfaction d'un point de vue fiabilité, notamment en raison des risques de voir l'extrémité proximale du manchon se translater et la première bague se déchausser par rapport au récipient dans le cas d'une pression trop forte sur le récipient.However, these solutions do not give complete satisfaction from a reliability point of view, in particular because of the risks of seeing the proximal end of the sleeve translate and the first ring come off with respect to the container in the case of pressure. too strong on the container.

De plus, les biberons en matière souple peuvent présenter le désavantage de ne pas être aisés à assembler puisque les pièces d'assemblage ont du mal à être fixées sur la matière souple.In addition, bottles made of flexible material may have the disadvantage of not being easy to assemble since the assembly parts have difficulty being fixed on the flexible material.

Il existe également un besoin de disposer d'un biberon où le liquide contenu soit en contact avec de la silicone réputé sain et le moins en contact possible avec d'autres parties notamment liées à l'étanchéité et au serrage qui seraient en plastique et donc potentiellement contaminées par des perturbateurs endocriniens.There is also a need to have a bottle where the liquid contained is in contact with silicone reputed to be healthy and as little as possible in contact with other parts in particular related to sealing and tightening which would be made of plastic and therefore potentially contaminated with endocrine disruptors.

Il existe également un besoin de disposer d'un contenant dont l'intérieur est facilement nettoyable.There is also a need to have a container whose interior is easily cleanable.

Même si les problématiques évoquées ci-dessus sont présentées en lien avec le cas particulier d'un récipient à vocation de biberon, elles peuvent être associées à d'autres types de récipients comme les gourdes, les bouteilles ou d'autres types de récipients comme certains réservoirs pour liquide ou gaz.Even if the problems mentioned above are presented in connection with the particular case of a receptacle intended for a baby bottle, they can be associated with other types of receptacles such as gourds, bottles or other types of receptacles such as certain tanks for liquid or gas.

Dans ce contexte, il existe un besoin de disposer d'un récipient destiné à contenir un fluide (fluide ou liquide), de type biberon, bouteille, gourde ou réservoir pour un gaz ou un liquide, qui soit robuste, sain et hygiénique, pratique à utiliser et à nettoyer, agréable au toucher tout en étant facile à fabriquer et offrant une grande liberté de conception du contenant, en termes de forme et de dimension.In this context, there is a need to have a container intended to contain a fluid (fluid or liquid), of the feeding bottle, bottle, canteen or tank type for a gas or a liquid, which is robust, healthy and hygienic, practical to use and clean, pleasant to the touch while being easy to manufacture and offering great freedom of design of the container, in terms of shape and size.

  • une seconde bague annulaire délimitant un second filetage venant en prise avec le premier filetage par vissage de la seconde bague annulaire par rapport à la première bague annulaire, de sorte que l'épaulement inférieur du dispositif de fermeture amovible et l'épaulement supérieur du manchon sont aptes à être enserrés et comprimés mutuellement entre la première bague annulaire et la seconde bague annulaire par l'action de vissage de la seconde bague annulaire sur la première bague annulaire
dans lequel le contenant délimite un épaulement externe dont la face libre est globalement orthogonale à la direction d'extension longitudinale du manchon tubulaire, et dans lequel la deuxième bague annulaire délimite un épaulement primaire de sorte que l'épaulement primaire de la deuxième bague annulaire soit en appui avec l'épaulement externe du contenant lorsque la deuxième bague annulaire enserre l'épaulement inférieur du dispositif de fermeture amovible et l'épaulement supérieur du manchon en coopération avec la première bague annulaire.This object can be achieved by providing a container intended to contain a fluid, of the baby bottle, bottle, canteen or tank type for a gas or a liquid, the container comprising a container defining an internal volume formed in a flexible material and capped with a tubular sleeve whose proximal end delimits a housing in combination with the container, and whose distal end delimits an upper opening allowing the flow of fluid to or from the internal volume and comprising an upper shoulder projecting radially towards the outside of the sleeve, a removable closure device formed in a flexible material, and comprising a lower shoulder adapted to collaborate with the upper shoulder of the sleeve so that a seal is created when the lower shoulder and the upper shoulder are compressed one against the other, a coupling system allowing maintenance and mutual compression of the lower shoulder of the removable closure device and the upper shoulder of the sleeve, and made up of the following two parts, independent of each other and both made of a rigid material:
  • a first annular ring defining a first thread and a collar able to be inserted into the housing by elastic deformation of the proximal end of the sleeve, the first annular ring being positioned around the sleeve, under the upper shoulder, by deformation upper shoulder elastic,
  • a second annular ring delimiting a second thread engaging the first thread by screwing the second annular ring relative to the first annular ring, so that the lower shoulder of the removable closure device and the upper shoulder of the sleeve are adapted to be sandwiched and mutually compressed between the first annular ring and the second annular ring by the screwing action of the second annular ring on the first annular ring
in which the container delimits an external shoulder, the free face of which is generally orthogonal to the direction of longitudinal extension of the sleeve tubular, and in which the second annular ring delimits a primary shoulder such that the primary shoulder of the second annular ring bears against the external shoulder of the container when the second annular ring encloses the lower shoulder of the removable closure device and the upper shoulder of the sleeve in cooperation with the first annular ring.

Certains aspects préférés mais non limitatifs de ce récipient sont les suivants :
Le second filetage de la deuxième bague annulaire est agencé en saillie depuis une face intérieure de la deuxième bague annulaire.Some preferred but non-limiting aspects of this container are as follows:
The second thread of the second annular ring is arranged projecting from an inner face of the second annular ring.

La collerette de la première bague annulaire s'étend en saillie depuis une face extérieure de la première bague annulaire et le logement est agencé dans un plan globalement orthogonal à la direction d'extension longitudinale du machon de sorte que la collerette préalablement insérée dans le logement est maintenue bloquée contre au moins un mouvement de translation le long de la direction d'extension longitudinale du manchon.The collar of the first annular ring extends projecting from an outer face of the first annular ring and the housing is arranged in a plane generally orthogonal to the direction of longitudinal extension of the sleeve so that the collar previously inserted into the housing is kept locked against at least one translational movement along the longitudinal direction of extension of the sleeve.

La collerette de la première bague annulaire présente une épaisseur supérieure à l'épaisseur du logement vue suivant la direction d'extension longitudinale afin que les parois délimitant le logement soient comprimées par la colerette lorsque la colerette de la première bague annulaire est insérée dans le logement d'une manière telle que la première bague annulaire soit maintenue bloquée contre un mouvement de rotation autour de la direction d'extension longitudinale du manchon.The collar of the first annular ring has a thickness greater than the thickness of the housing seen along the direction of longitudinal extension so that the walls delimiting the housing are compressed by the collar when the collar of the first annular ring is inserted into the housing in such a way that the first annular ring is kept locked against rotational movement around the longitudinal direction of extension of the sleeve.

L'épaulement inférieur du dispositif de fermeture amovible comporte une face plane et un rebord globalement orthogonal à la face plane de sorte à former un crochet, et la deuxième bague annulaire délimite un épaulement secondaire distal de l'épaulement primaire et dont la forme est complémentaire de celle délimitée par l'épaulement inférieur du dispositif de fermeture amovible de sorte que lorsque la deuxième bague annulaire enserre l'épaulement inférieur du dispositif de fermeture amovible et l'épaulement supérieur du manchon en coopération avec la première bague annulaire, le dispositif de fermeture amovible est bloqué contre au moins un mouvement de translation globalement perpendiculaire à l'axe d'extension longitudinal du manchon.The lower shoulder of the removable closure device has a flat face and a rim generally orthogonal to the flat face so as to form a hook, and the second annular ring defines a secondary shoulder distal to the primary shoulder and whose shape is complementary from that delimited by the lower shoulder of the removable closure device so that when the second annular ring encloses the lower shoulder of the removable closure device and the upper shoulder of the sleeve in cooperation with the first annular ring, the closure device removable is blocked against at least one translational movement generally perpendicular to the longitudinal axis of extension of the sleeve.

Les parois du manchon tubulaire ont une épaisseur inférieure à l'une quelconque des parois du contenant.The walls of the tubular sleeve have a thickness less than any of the walls of the container.

Le manchon est apte à être placé sélectivement dans au moins une première position relevée où le manchon est placé à l'extérieur du contenant et au moins une deuxième position repliée où le manchon est replié vers l'intérieur du contenant.The sleeve is adapted to be placed selectively in at least a first raised position where the sleeve is placed outside the container and at the least a second folded position where the sleeve is folded towards the inside of the container.

Au moins une partie de la face interne du volume interne du contenant agencée vers l'extrémité proximale du manchon décrit un angle de dépouille supérieur à 40° par rapport à la direction d'extension longitudinale du manchon.At least a part of the internal face of the internal volume of the container arranged towards the proximal end of the sleeve describes a draft angle greater than 40° with respect to the direction of longitudinal extension of the sleeve.

Le dispositif de fermeture amovible comprend une tétine.The removable closure device includes a teat.

Le récipient comprend un couvercle apte à se monter de manière amovible sur la deuxième bague annulaire de sorte à recouvrir la tétine, le récipient constituant un biberon destiné à contenir un liquide en vue de sa consommation à travers la tétine.The container comprises a lid adapted to be mounted in a removable manner on the second annular ring so as to cover the teat, the container constituting a bottle intended to contain a liquid with a view to its consumption through the teat.

Le contenant délimite en partie une forme générale de cylindre galbé dont une génératrice a une forme arquée telle que le contenant présente un diamètre maximal sensiblement à mi-hauteur.The container partly delimits the general shape of a curved cylinder, one generatrix of which has an arcuate shape such that the container has a maximum diameter substantially at mid-height.

Le contenant comporte une face support agencée pour permettre au contenant d'être posé sur un support plan de façon stable, la face support ayant une forme centrale ondulée de sorte que seule la périphérie de la face support est en appui sur le support plan.The container has a support face arranged to allow the container to be placed on a flat support in a stable manner, the support face having a corrugated central shape so that only the periphery of the support face bears on the flat support.

Le contenant et le dispositif de fermeture sont formés dans une silicone.The container and the closure device are formed in a silicone.

EXPOSE DETAILLE DE MODES DE REALISATION PARTICULIERSDETAILED EXPLANATION OF PARTICULAR EMBODIMENTS

Les figures 1 à 7 détaillent un exemple de récipient 10 selon l'invention. Le récipient 10 représenté concerne un cas particulier en aucun cas limitatif des champs d'application possibles pour l'invention.The figures 1 to 7 detail an example of container 10 according to the invention. The container 10 represented relates to a particular case in no way limiting the possible fields of application for the invention.

Plus précisément, le récipient 10 des figures 1 à 7 est configuré, comme il le sera détaillé plus loin, de sorte à constituer un biberon capable de contenir et de délivrer de manière contrôlée une préparation liquide pour enfant ou nourrisson, au travers d'une tétine.More specifically, the container 10 of the figures 1 to 7 is configured, as will be detailed below, so as to constitute a bottle capable of containing and delivering in a controlled manner a liquid preparation for a child or infant, through a teat.

L'organisation d'une telle tétine ne présente aucune limitation en ce qui concerne sa forme (qu'elle soit de forme anatomique ou non, par exemple).The organization of such a pacifier does not present any limitation with regard to its shape (whether it is anatomically shaped or not, for example).

Mais le lecteur doit conserver à l'esprit que l'invention peut indifféremment être adaptée de sorte à constituer un récipient de type gourde, bouteille ou équivalent, ou un réservoir pour gaz ou liquide, par de simples adaptations à la portée de l'Homme du Métier à partir des principes de l'invention qui vont être énoncés plus loin en application au cas particulier d'un biberon.But the reader must keep in mind that the invention can either be adapted so as to constitute a container of the gourd, bottle or equivalent type, or a reservoir for gas or liquid, by simple adaptations within the reach of man. of the Trade based on the principles of the invention which will be stated later in application to the particular case of a baby bottle.

Ainsi, de manière générale, le récipient 10 est destiné à contenir un fluide (non représenté), qu'il s'agisse d'un liquide typiquement en vue de sa consommation, ou d'un gaz. Le récipient est formé en une matière souple et comprend un contenant 11 ayant une forme générale creuse, un peu à la manière d'un pot, de sorte à délimiter un volume interne 12, coiffé d'un manchon 15 tubulaire. Le manchon 15 tubulaire comprend une extrémité proximale qui délimite un logement 21 en combinaison avec le contenant 11. Le manchon 15 tubulaire comprend une extrémité distale qui délimite une ouverture supérieure 13 permettant l'écoulement du fluide vers ou depuis le volume interne 12. L'extrémité distale comporte également un épaulement supérieur 151 en saillie radialement vers l'extérieur du manchon 15. L'ouverture supérieure 13 permet l'écoulement du fluide vers ou depuis le volume interne 12. On entend par « coiffé » : « agencé en continuité du contenant ». Le manchon 15 tubulaire a un axe de symétrie qui est aussi appelé direction d'extension longitudinale 152. Cet axe est globalement aligné sur l'axe de révolution du récipient si celui-ci en contient un.Thus, in general, the container 10 is intended to contain a fluid (not shown), whether it is a liquid typically for consumption, or a gas. The container is made of a flexible material and comprises a container 11 having a generally hollow shape, somewhat like a pot, so as to delimit an internal volume 12, capped with a tubular sleeve 15 . The tubular sleeve 15 comprises a proximal end which delimits a housing 21 in combination with the container 11. The tubular sleeve 15 comprises a distal end which delimits an upper opening 13 allowing the flow of fluid to or from the internal volume 12. distal end also includes an upper shoulder 151 projecting radially outwards from the sleeve 15. The upper opening 13 allows the flow of fluid to or from the internal volume 12. container". The tubular sleeve 15 has an axis of symmetry which is also called the direction of longitudinal extension 152. This axis is generally aligned with the axis of revolution of the container if the latter contains one.

Dans le texte les termes « sensiblement » ou « globalement » signifient à 10% ou à 10° prés.In the text, the terms “substantially” or “overall” mean to within 10% or within 10°.

Le contenant 11 est très avantageusement formé dans une matière souple, permettant de rendre le récipient 10 incassable et de faciliter sa manipulation. Notamment, mais de manière non limitative, le contenant 11 est formé de manière monobloc en une silicone ou polysiloxane. L'avantage de cette matière particulière est de présenter un toucher pour la main relativement proche de la peau humaine afin de favoriser le développement émotionnel du nourrisson ou de l'enfant utilisateur, tout en étant hygiénique en limitant les risques de contaminations vis-à-vis du liquide contenu, ces deux aspects étant essentiels dans le cas particulier d'une application de type biberon. Il reste possible d'envisager d'autres matières souples adaptées aux fonctions recherchées pour le récipient 10, notamment des matières ayant des caractéristiques similaires à celles de la silicone, par exemple des caoutchoucs naturels ou une matière choisie parmi la liste des thermoplastiques élastomères.The container 11 is very advantageously formed in a flexible material, making it possible to make the container 10 unbreakable and to facilitate its handling. In particular, but in a non-limiting manner, the container 11 is formed in one piece from a silicone or polysiloxane. The advantage of this particular material is to present a touch for the hand relatively close to human skin in order to promote the emotional development of the infant or child user, while being hygienic by limiting the risks of contamination vis-à-vis vis the liquid contained, these two aspects being essential in the particular case of a bottle-type application. It remains possible to envisage other flexible materials suitable for the functions sought for the container 10, in particular materials having characteristics similar to those of silicone, for example natural rubbers or a material chosen from the list of elastomeric thermoplastics.

Le récipient 10 comprend également un dispositif de fermeture amovible 22 dont le but est d'assurer la fermeture du contenant 11 dans sa partie supérieure, afin d'éviter au fluide présent dans le volume interne 12 de s'en écouler sauf à s'écouler de manière contrôlée à travers le dispositif de fermeture amovible 22, par exemple ici à travers la tétine déjà évoquée ci-avant.The container 10 also comprises a removable closure device 22 whose purpose is to ensure the closure of the container 11 in its upper part, in order to prevent the fluid present in the internal volume 12 from flowing out of it except to flow in a controlled manner through the removable closure device 22, for example here through the pacifier already mentioned above.

Le dispositif de fermeture amovible 22 comporte un épaulement inférieur 221 apte à collaborer avec l'épaulement supérieur 151 du manchon 15 de sorte qu'une étanchéité est créée lorsque l'épaulement inférieur 221 et l'épaulement supérieur 151 sont comprimés l'un contre l'autre.The removable closure device 22 comprises a lower shoulder 221 adapted to collaborate with the upper shoulder 151 of the sleeve 15 so that a seal is created when the lower shoulder 221 and the upper shoulder 151 are compressed against one another. 'other.

Dans le cas particulier du récipient 10 assurant une fonction de biberon comme c'est le cas sur les figures 1 à 5, le dispositif de fermeture amovible 22 peut notamment comprendre une tétine. Le dispositif de fermeture amovible 22 peut ainsi être formé dans une matière souple comme celle décrite ci-avant et préférentiellement dans une silicone.In the particular case of the container 10 providing a bottle function as is the case on the figures 1 to 5 , the removable closure device 22 may in particular comprise a pacifier. The removable closure device 22 can thus be formed in a flexible material like that described above and preferably in a silicone.

Il est bien évident, néanmoins, que la nature et la conception du dispositif de fermeture amovible dépendra de la fonction recherchée pour le récipient 10. Ainsi, le dispositif de fermeture amovible 22 peut être différent de celui représenté, notamment dans le cas où le récipient 10 est de type bouteille, gourde, ou autre réservoir pour gaz ou liquide.It is obvious, however, that the nature and design of the removable closure device will depend on the function sought for the container 10. Thus, the removable closure device 22 may be different from that shown, in particular in the case where the container 10 is of the bottle, canteen or other gas or liquid tank type.

Le récipient 10 comprend aussi un système de couplage servant d'interface entre le contenant 11 et le dispositif de fermeture amovible 22. Le système de couplage est monté sur le contenant 11 au niveau de l'ouverture supérieure 13 par un assemblage mécanique, évitant le recours aux techniques de surmoulage. Le système de couplage permet un maintien et une mise en compression mutuelle de l'épaulement inférieur 221 du dispositif de fermeture amovible 22 et de l'épaulement supérieur 151 du manchon 15.The container 10 also comprises a coupling system serving as an interface between the container 11 and the removable closure device 22. The coupling system is mounted on the container 11 at the level of the upper opening 13 by a mechanical assembly, avoiding the use of overmolding techniques. The coupling system allows maintenance and mutual compression of the lower shoulder 221 of the removable closure device 22 and of the upper shoulder 151 of the sleeve 15.

Le système de couplage est constitué de la combinaison de deux pièces indépendantes l'une de l'autre, toutes deux formées dans une matière rigide, à savoir une première bague annulaire 16 et une deuxième bague annulaire 17. Avantageusement, et pour des raisons de simplicité de fabrication, chacune de ces deux pièces peut notamment être obtenue par une technique de moulage. La matière utilisée peut être de type métallique comme par exemple un acier choisi parmi la liste des aciers inoxydables ou un laiton, ou de type à base de plastique comme par exemple un polypropylène, ce qui est avantageux dans le cas particulier d'un récipient 10 à vocation de biberon.The coupling system consists of the combination of two mutually independent parts, both formed from a rigid material, namely a first annular ring 16 and a second annular ring 17. Advantageously, and for reasons of simplicity of manufacture, each of these two parts can in particular be obtained by a molding technique. The material used can be of the metallic type such as for example a steel chosen from the list of stainless steels or a brass, or of the plastic-based type such as for example a polypropylene, which is advantageous in the particular case of a container 10 for bottle use.

La première bague annulaire 16 délimite un premier filetage 18 et une collerette 161 apte à venir s'insérer par déformation élastique de l'extrémité proximale du manchon 15, dans le logement 21. La première bague annulaire 16 vient se positionner autour du manchon 15 par déformation élastique de l'épaulement supérieur 151 du manchon 15.The first annular ring 16 defines a first thread 18 and a flange 161 capable of being inserted by elastic deformation of the proximal end of the sleeve 15, in the housing 21. The first annular ring 16 is positioned around the sleeve 15 by elastic deformation of the upper shoulder 151 of the sleeve 15.

Dans un mode réalisation illustré sur les figures 2, 4 et 5, la collerette 161 de la première bague annulaire 16 s'étend en saillie depuis une face extérieure de la première bague annulaire 16 et le logement 21 est agencé dans un plan globalement orthogonal à la direction d'extension longitudinale 152 du machon 15 tubulaire de sorte que la collerette 161 étant préalablement insérée dans le logement 21, elle est maintenue bloquée contre au moins un mouvement de translation le long de la direction d'extension longitudinale du machon 15 tubulaire. Ceci permet avantageusement de garder l'étanchéité même en cas où le dispositif de fermeture amovible 22 est tiré par exemple si un enfant voulait arracher la tétine du biberon.In one embodiment illustrated on the figure 2 , 4 and 5 , the flange 161 of the first annular ring 16 projects from an outer face of the first annular ring 16 and the housing 21 is arranged in a plane generally orthogonal to the direction of longitudinal extension 152 of the sleeve 15 tubular so that the collar 161 being previously inserted into the housing 21, it is kept locked against at least one translational movement along the direction of longitudinal extension of the tubular sleeve 15 . This advantageously makes it possible to keep the seal even in the event that the removable closure device 22 is pulled, for example if a child wanted to tear the nipple from the bottle.

Dans un autre mode de réalisation illustré sur les figures 2, 4 et 5, la collerette 161 de la première bague annulaire 16 est d'épaisseur supérieure à la taille du logement 21 vue suivant la direction d'extension longitudinale 152 de sorte que les parois formant le logement 21 sont comprimées lorsque la colerette 161 de la première bague annulaire 16 est insérée dans le logement 21. Cela entraîne que la première bague annulaire 16 est maintenue bloquée contre au moins un mouvement de rotation autour de la direction d'extension longitudinale 152 du machon 15 tubulaire. Ceci permet avantageusement que la première bague annulaire 16 ne tourne pas lorsque la deuxième bague annulaire 17 est vissée sur elle.In another embodiment illustrated in the figure 2 , 4 and 5 , the collar 161 of the first annular ring 16 is thicker than the size of the housing 21 seen along the direction of longitudinal extension 152 so that the walls forming the housing 21 are compressed when the collar 161 of the first annular ring 16 is inserted into the housing 21. This causes the first annular ring 16 to be kept locked against at least one rotational movement around the direction of longitudinal extension 152 of the tubular sleeve. This advantageously allows the first annular ring 16 not to rotate when the second annular ring 17 is screwed onto it.

La seconde bague annulaire 17 délimite un second filetage 19 venant en prise avec le premier filetage 18 par vissage de la seconde bague annulaire 17 par rapport à la première bague annulaire 16, de sorte que l'épaulement inférieur 221 du dispositif de fermeture amovible 22 et l'épaulement supérieur 151 du manchon 15 soient enserrés et comprimés mutuellement entre la première bague annulaire 16 et la seconde bague annulaire 17 par l'action de vissage de la seconde bague annulaire 17 sur la première bague annulaire 16.The second annular ring 17 defines a second thread 19 engaging with the first thread 18 by screwing the second annular ring 17 relative to the first annular ring 16, so that the lower shoulder 221 of the removable closure device 22 and the upper shoulder 151 of the sleeve 15 are clamped and mutually compressed between the first annular ring 16 and the second annular ring 17 by the screwing action of the second annular ring 17 on the first annular ring 16.

Dans un mode de réalisation, le second filetage 19 de la deuxième bague annulaire 17 est agencé en saillie depuis une face intérieure de la deuxième bague annulaire 17.In one embodiment, the second thread 19 of the second annular ring 17 is arranged projecting from an inner face of the second annular ring 17.

Le système de couplage permet donc le maintien et la mise en compression mutuelle de l'épaulement inférieur 221 du dispositif de fermeture amovible 22 et de l'épaulement supérieur 151 du manchon 15. Le vissage de la seconde bague annulaire 17 sur la première bague annulaire 16 entraîne donc l'étanchéification du récipient 10.The coupling system therefore allows the maintenance and the mutual compression of the lower shoulder 221 of the removable closure device 22 and of the upper shoulder 151 of the sleeve 15. The screwing of the second annular ring 17 on the first annular ring 16 therefore causes the sealing of the container 10.

Dans un mode de réalisation non représenté, le premier filetage 18 ou le second filetage 19 délimitent un point dur de sorte que lorsque le second filetage 19 est vissé dans le premier filetage 18 avant le point dur alors la force de vissage est notoirement plus faible que lorsque le vissage passe le point dur. Ceci a pour effet de signifier que le vissage est complètement serré.In an embodiment not shown, the first thread 18 or the second thread 19 delimit a hard point so that when the second thread 19 is screwed into the first thread 18 before the hard point then the screwing force is notoriously weaker than when the screwing passes the hard point. This has the effect of indicating that the screw connection is completely tight.

Dans un autre mode de réalisation non représenté, le premier filetage 18 délimite une fin de course de sorte que, lorsque le second filetage 19 est en action de vissage en collaboration avec le premier filetage 18, alors la compression mutuelle de l'épaulement inférieur 221 du dispositif de fermeture amovible 22 et de l'épaulement supérieur 151 du manchon 15 atteint une limite supérieure lorsque le second filetage 19 atteint la fin de course.In another embodiment not shown, the first thread 18 delimits a limit switch so that, when the second thread 19 is in screwing action in collaboration with the first thread 18, then the mutual compression of the lower shoulder 221 of the removable closure device 22 and of the upper shoulder 151 of the sleeve 15 reaches an upper limit when the second thread 19 reaches the end of its travel.

Selon un mode de réalisation non-limitatif, le contenant 11 délimite un épaulement externe 111 dont la face libre est globalement orthogonale à la direction d'extension longitudinale 152 du manchon 15. La deuxième bague annulaire 17 délimite également un épaulement primaire 171 de sorte que l'épaulement primaire 171 de la deuxième bague annulaire 17 est en appui avec l'épaulement externe 111 du contenant 11 lorsque la deuxième bague annulaire 17 enserre l'épaulement inférieur 221 du dispositif de fermeture amovible 22 et l'épaulement supérieur 151 du manchon 15 en coopération avec la première bague annulaire 16. Ceci permet avantageusement de bloquer en translation l'extrémité proximale du manchon 15 entre les premières et deuxièmes bagues annulaires 16 et 17 de sorte qu'une pression sur le récipient 11 ne risque pas de déchausser la collerette 161.According to a non-limiting embodiment, the container 11 delimits an external shoulder 111 whose free face is generally orthogonal to the direction of longitudinal extension 152 of the sleeve 15. The second annular ring 17 also delimits a primary shoulder 171 so that the primary shoulder 171 of the second annular ring 17 bears against the outer shoulder 111 of the container 11 when the second annular ring 17 encloses the lower shoulder 221 of the removable closure device 22 and the upper shoulder 151 of the sleeve 15 in cooperation with the first annular ring 16. This advantageously makes it possible to lock the proximal end of the sleeve 15 in translation between the first and second annular rings 16 and 17 so that pressure on the container 11 does not risk removing the collar 161.

Selon un mode de réalisation particulier non limitatif illustré sur la figure 5, l'épaulement inférieur 221 du dispositif de fermeture amovible 22 comporte une face plane 221a et un rebord 221b globalement orthogonal à la face plane 221a de sorte à former un crochet. La deuxième bague annulaire 17 délimite également un épaulement secondaire 172 distal de l'épaulement primaire 171 dont la forme est complémentaire à celle délimitée par l'épaulement inférieur 221. Ainsi lorsque la deuxième bague annulaire 17 enserre l'épaulement inférieur 221 du dispositif de fermeture amovible 22 et l'épaulement supérieur 151 du manchon 15 en coopération avec la première bague annulaire 16 alors le dispositif de fermeture amovible 22 est bloqué contre au moins un mouvement de translation globalement perpendiculaire à l'axe d'extension 152 longitudinal du manchon 15.According to a particular non-limiting embodiment illustrated in the figure 5 , the lower shoulder 221 of the removable closure device 22 has a flat face 221a and a flange 221b generally orthogonal to the flat face 221a so as to form a hook. The second annular ring 17 also delimits a secondary shoulder 172 distal to the primary shoulder 171 whose shape is complementary to that delimited by the lower shoulder 221. Thus when the second annular ring 17 encloses the lower shoulder 221 of the closing device removable 22 and the upper shoulder 151 of the sleeve 15 in cooperation with the first annular ring 16 then the removable closure device 22 is blocked against at least one translational movement generally perpendicular to the axis of extension 152 longitudinal of the sleeve 15.

Selon un autre mode de réalisation particulier non limitatif illustré sur les figures 6 et 7, le manchon 15 est apte à être placé sélectivement dans au moins une première position relevée illustrée sur la figure 7 où le manchon 15 est placé à l'extérieur du contenant 11 et au moins une deuxième position repliée où le manchon 15 est replié vers l'intérieur du contenant 11 comme illustré sur la figure 6. Cette deuxième position permet avantageusement de pouvoir atteindre le fond du contenant 11 avec les doigts par exemple pour avantageusement mieux en nettoyer l'intérieur. Un autre avantage de cette position est qu'elle permet un montage ou un démontage aisé de la première bague annulaire 16. Egalement, cette deuxième position permet avantageusement de libérer l'accès au logement 21 pour son nettoyage manuel.According to another particular non-limiting embodiment illustrated in the figures 6 and 7 , the sleeve 15 is adapted to be placed selectively in at least a first raised position illustrated in the figure 7 where the sleeve 15 is placed outside the container 11 and at least a second folded position where the sleeve 15 is folded towards the inside of the container 11 as illustrated in the figure 6 . This second position advantageously makes it possible to be able to reach the bottom of the container 11 with the fingers, for example to advantageously better clean the interior. Another advantage of this position is that it allows easy assembly or disassembly of the first annular ring 16. Also, this second position advantageously makes it possible to free up access to the housing 21 for its manual cleaning.

Selon un mode de réalisation particulier non limitatif illustré sur la figure 5, les parois du manchon 15 tubulaire ont une épaisseur inférieure à l'une quelconque des parois du contenant 11. Cela permet avantageusement de donner une souplesse au manchon 15 et par exemple d'obtenir une des positions décrites précédemment.According to a particular non-limiting embodiment illustrated in the figure 5 , the walls of the tubular sleeve 15 have a thickness less than any of the walls of the container 11. This advantageously makes it possible to give flexibility to the sleeve 15 and for example to obtain one of the positions described above.

Selon un autre mode de réalisation particulier non limitatif illustré sur la figure 4, au moins une partie de la face interne du volume interne 12 du contenant 11 agencée vers l'extrémité proximale du manchon 15 décrit un angle de dépouille 121 supérieur à 40° par rapport à la direction d'extension longitudinale 152 du manchon 15. Cela permet avantageusement de faciliter le nettoyage de l'intérieur, d'améliorer la flexibilité du manchon pour permettre par exemple d'obtenir l'une ou l'autre des positions présentées ci-avant mais également de faciliter le versement du liquide contenu dans le volume intérieur 12.According to another particular non-limiting embodiment illustrated in the figure 4 , at least a part of the internal face of the internal volume 12 of the container 11 arranged towards the proximal end of the sleeve 15 describes a draft angle 121 greater than 40° with respect to the direction of longitudinal extension 152 of the sleeve 15. This advantageously makes it easier to clean the interior, to improve the flexibility of the sleeve to allow for example to obtain one or other of the positions presented above but also to facilitate the pouring of the liquid contained in the volume interior 12.

Selon un mode de réalisation particulier non limitatif illustré sur les figures 2 et 5, le contenant 11 présente une forme générale de cylindre galbé dont une génératrice a une forme arquée telle que le contenant 11 présente un diamètre maximal 28 sensiblement au centre de la hauteur 29 du contenant 11. Une telle forme présente l'avantage de faciliter la préhension du récipient 10, ce qui peut être essentiel vis-à-vis des nourrissons ou des enfants.According to a particular non-limiting embodiment illustrated in the figure 2 and 5 , the container 11 has the general shape of a curved cylinder, one generatrix of which has an arcuate shape such that the container 11 has a maximum diameter 28 substantially at the center of the height 29 of the container 11. Such a shape has the advantage of facilitating gripping of the container 10, which can be essential vis-à-vis infants or children.

Selon un mode de réalisation particulier non limitatif illustré sur la figure 5, le contenant 11 comporte une face support 11a agencée pour permettre au contenant 11 d'être posé sur un support plan de façon stable, la face support 11a ayant une forme centrale ondulée de sorte que seule la périphérie de la face support 11a est en appui sur le support plan.According to a particular non-limiting embodiment illustrated in the figure 5 , the container 11 has a support face 11a arranged to allow the container 11 to be placed on a flat support in a stable manner, the support face 11a having a corrugated central shape so that only the periphery of the support face 11a is supported on the flat support.

Dans l'exemple ou le récipient est un biberon, le récipient 10 peut comprendre un couvercle 20 apte à se monter de manière amovible sur la deuxième bague annulaire 17 de sorte à recouvrir la tétine.In the example where the container is a baby bottle, the container 10 may include a lid 20 capable of being removably mounted on the second annular ring 17 so as to cover the teat.

Le récipient 10 qui vient d'être décrit, outre les avantages déjà décrits, est robuste, hygiénique, pratique à utiliser et à nettoyer, agréable au toucher, facile à fabriquer, et peu limitant quant à la liberté de conception du contenant 11.The container 10 which has just been described, in addition to the advantages already described, is robust, hygienic, practical to use and clean, pleasant to the touch, easy to manufacture, and not very limiting as to the freedom of design of the container 11.
