Abstract

Improvement to stopper devices made of injected plastic material for bottles whose neck is smooth and not threaded. This improvement consists in interposing, between the external part of the neck or cap (2) and the internal part of the neck or stopper (1), an intermediate part or insert (3) held in place in the cap (2) by outer capping or engagement. This intermediate part (3) is made from a material making it possible to ensure an efficient assembly between itself and the stopper (1) by gluing.

Description

Perfectionnement aux dispositifs de bouchage en matière plastique injectée pour bouteilles dont le goulot est lisse et non fileté. Improvement to injection-molded plastic corking devices for bottles with a smooth, non-threaded neck.

Une forme courante de bouchage est réalisée par un dispositif composé de deux piéces. Une première pièce (1) Figure 1 en matière naturelle tel le liège ou agglomeré de liège est collée à l'intérieur d'un caouchon (2) en matière plastique injectée. A common form of closure is achieved by a device made up of two parts. A first part (1) Figure 1 made of natural material such as cork or agglomerated cork is bonded to the inside of a cap (2) made of injected plastic.

Ce capuchon (2) réalisé le plus souvent en ploypropylène ou polyéthylène matières choisies pour les facilitées de moulage et surtout pour leur aptitude à donner des rendus esthétiques particulièrs. This cap (2) most often made of ploypropylene or polyethylene materials chosen for ease of molding and especially for their ability to give particular aesthetic results.

Cette matière, de part sa nature, a pour caractéristique d'être pratiquement incollable. II en résulte donc de grosses difficultés d'assemblage entre la pièce (1) et la pièce (2). This material, by its nature, has the characteristic of being practically unbeatable. This therefore results in great assembly difficulties between the part (1) and the part (2).

Cela provoque une dissociation de ces pièces au moment du débouchage, le recours a un tire bouchon, la non réutilisation de l'ensemble pour refermer une bouteille dont le contenu est partiellement consommé. This causes these parts to be dissociated when uncorking, the use of a corkscrew, the non-reuse of the assembly to close a bottle whose content is partially consumed.

Ce perfectionnement selon l'invention permet de remédier à ces inconvénients. This improvement according to the invention overcomes these drawbacks.

Il consiste à interposer entre la partie injectée en polypropylène ou polyéthylène (2) et le bouchon (1) une pièce intercalaire (3) Figure 2. It consists of interposing between the injected polypropylene or polyethylene part (2) and the plug (1) an intermediate piece (3) Figure 2.

Cette pièce (3) de forme sensiblement tubulaire sera réalisée en matière compatible à un bon collage avec le bouchon (1). A titre d'exemple, non limitatif, cela pourra être une matière plastique collable tel le polystyrène, métal, voire du bois.This piece (3) of substantially tubular shape will be made of material compatible with good bonding with the plug (1). By way of non-limiting example, this could be a stickable plastic material such as polystyrene, metal, or even wood.

Pour que cette pièce intercalaire (3) soit efficacement solidaire du capuchon (2) elle pourra être surmoulée par la matière plastique au cours de l'injection de cette dernière au moment du moulage du capuchon (2). Pour bien maintenir cette pièce (3) on aura ménagé sur son pourtour extérieur des stries, moletages, rainures, isolement ou en association, ou tout autres procédés connus qui s'opposeront à son extraction. Le bouchon (1) sera alors collé d'une façon efficace à l'intérieur de cette pièce intercalaire (3). La Figure 3 représente un type d'insert (3) moleté et rainuré à titre d'exemple non limitatif. So that this intermediate piece (3) is effectively secured to the cap (2) it can be molded by the plastic during the injection of the latter during the molding of the cap (2). To properly maintain this part (3) we will have formed on its outer periphery streaks, knurling, grooves, isolation or association, or any other known methods which will oppose its extraction. The plug (1) will then be stuck efficiently inside this intermediate piece (3). Figure 3 shows a type of insert (3) knurled and grooved by way of non-limiting example.

Dans une autre forme de réalisation cette pièce intercalaire (3) pourra être insérée dans la pièce (2) après moulage de cette dernière. In another embodiment, this intermediate piece (3) can be inserted into the piece (2) after molding of the latter.

Elle sera maintenue en place par clipsage à l'aide de rainures conformes de telle manière que l'insertion soit possible par déformation de la matière et l'extraction impossible, système connu par l'homme de l'art. Figure 4.It will be held in place by clipping using conforming grooves in such a way that insertion is possible by deformation of the material and impossible extraction, a system known to those skilled in the art. Figure 4.

Le perfectionnement selon l'invention est destiné aux dispositifs de bouchage en matière plastique pour bouteilles dont le goulot est lisse et non fileté.  The improvement according to the invention is intended for plastic corking devices for bottles whose neck is smooth and not threaded.
