Abstract

The head (1) has a base (3) on which a projecting lug (4) is situated, where the lug cooperates with a stopper body during assembling the body and the lug. The lug includes an opening emerging laterally at two ends to pass completely through the lug to ensure anchoring of the body with the head. The lug is in elongate shape, and the opening is in shape flared along the longitudinal direction of the lug, where the widest part of the opening is placed on a side of the free end of lug. The lug is in non-symmetry revolution shape to prevent the body rotating about the lug.

Description

La présente invention concerne une tête de bouchon. Elle concerne encore un bouchon pour récipient notamment mis en oeuvre pour obturer une bouteille.The present invention relates to a plug head. It also relates to a cap for a container used in particular for closing a bottle.

On connaît des bouchons qui comprennent une portion cylindrique en liège ou dans une matière synthétique, encore appelée corps de bouchon, dont une extrémité est rendue solidaire d'une tête en matière plastique par collage.Corks are known which comprise a cylindrical portion made of cork or a synthetic material, also called a plug body, one end of which is secured to a plastic head by gluing.

Ces bouchons destinés au domaine alimentaire doivent respecter des normes très sévères.These caps for the food industry must meet very strict standards.

Or, la mise en oeuvre de colles aptes au contact alimentaire ne permet pas, de part les limitations de leur composition chimique, de garantir une parfaite adhésion dans un environnement soumis à des conditions extrêmes. On a tenté de résoudre ce problème en proposant successivement :

  • des bouchons dont la liaison entre la tête et le corps de bouchon est améliorée par un élément cylindrique plein formant saillie et pénétrant dans un trou borgne du corps de bouchon,
  • des bouchons ne comportant pas de colle et dont la liaison entre la tête de bouchon et le corps de bouchon, est réalisée par surmoulage.
However, the implementation of glues suitable for food contact does not allow, due to the limitations of their chemical composition, to ensure perfect adhesion in an environment subject to extreme conditions. We tried to solve this problem by proposing successively:
  • plugs whose connection between the head and the plug body is improved by a solid cylindrical member projecting and penetrating into a blind hole of the plug body,
  • corks having no glue and whose connection between the cap head and the plug body is made by overmolding.

Cependant, on observe souvent la séparation du corps de bouchon et de la tête lors de l'ouverture d'une bouteille équipée d'un tel bouchon en raison de problèmes d'adhérence entre ces éléments.However, it is often observed the separation of the cap body and the head when opening a bottle equipped with such a cap due to problems of adhesion between these elements.

En utilisation, cet ensemble est, en effet, soumis à des contraintes mécaniques de traction notamment pouvant résulter en un arrachement de la tête de bouchon.In use, this assembly is, in fact, subjected to mechanical tensile stresses in particular that can result in tearing of the plug head.

Il convient donc d'augmenter la force de liaison, ou l'accrochage, entre le corps de bouchon et la tête de bouchon.It is therefore necessary to increase the binding force, or the attachment, between the plug body and the plug head.

La présente invention vise à pallier ces divers inconvénients en proposant une tête de bouchon, simple dans sa conception et dans son mode opératoire, économique et assurant une meilleure accroche entre la tête de bouchon et le corps de bouchon.The present invention aims to overcome these various drawbacks by proposing a cap head, simple in its design and its operating mode, economic and ensuring better grip between the cap head and the cap body.

A cet effet, l'invention concerne une tête de bouchon destinée à être rendue solidaire d'un corps de bouchon pour former un bouchon pour récipient.To this end, the invention relates to a plug head intended to be secured to a plug body to form a plug for a container.

Selon l'invention, cette tête comprend un fond sur lequel un tenon est placé en saillie, ledit tenon étant destiné à coopérer avec ledit corps lors de l'assemblage de ce corps et de ce tenon. Ce tenon comporte au moins un évidement débouchant latéralement, à ses deux extrémités, de manière à traverser de part en part ledit tenon pour assurer l'ancrage dudit corps avec ladite tête.According to the invention, this head comprises a bottom on which a pin is placed projecting, said pin being intended to cooperate with said body during the assembly of the body and the tenon. This stud has at least one recess opening laterally at both ends, so as to pass right through said tenon to anchor said body with said head.

A titre purement illustratif, cette tête peut être métallique, en bois ou encore en matière plastique.For purely illustrative purposes, this head may be metal, wood or plastic.

La tête de bouchon peut être d'un seul tenant ou encore résulter de l'assemblage d'un tenon sur un fond. A titre illustratif, cet assemblage peut être réalisé par soudure.The cap head can be in one piece or result from the assembly of a tenon on a bottom. As an illustration, this assembly can be made by welding.

On entend par "un seul tenant" que ce clip est d'une seule pièce et ne résulte pas de l'assemblage de pièces initialement distinctes.The term "one piece" that this clip is a single piece and does not result from the assembly of initially separate parts.

Dans différents modes de réalisation particuliers de cette tête de bouchon, chacun ayant ses avantages particuliers et susceptibles de nombreuses combinaisons techniques possibles:

  • ce tenon ayant une forme allongée, ledit évidement a une forme évasée dans le sens longitudinal de ce tenon, la partie la plus large de cet évidement étant placée du côté de l'extrémité libre dudit tenon,
In various particular embodiments of this plug head, each having its particular advantages and susceptible to many possible technical combinations:
  • this tenon having an elongated shape, said recess has a flared shape in the longitudinal direction of this tenon, the widest part of this recess being placed on the side of the free end of said post,

Cette extrémité libre est définie par opposition à l'autre extrémité du tenon qui est solidaire du fond de la tête de bouchon.This free end is defined in opposition to the other end of the pin which is integral with the bottom of the plug head.

Cette forme évasée de l'évidement facilite avantageusement la circulation de la matière plastique lors du surmoulage du corps de bouchon autour du tenon. De plus, elle assure un apport supplémentaire de matière au niveau de la zone de l'assemblage corps/tenon qui est la plus soumise aux efforts d'arrachement.This flared shape of the recess advantageously facilitates the circulation of the plastic material during overmolding of the plug body around the tenon. In addition, it provides an additional supply of material at the area of the body / tenon assembly which is most subject to tearing efforts.

Cette forme évasée de l'évidement représente un équilibre entre amélioration de l'accrochage du corps de bouchon sur la tête de bouchon et affaiblissement mécanique du tenon.

  • ledit tenon a une forme non symétrique de révolution pour empêcher la rotation dudit corps autour audit tenon,
This flared shape of the recess represents a balance between improvement of the attachment of the plug body on the plug head and mechanical weakening of the post.
  • said tenon has a non-symmetrical shape of revolution to prevent rotation of said body around said tenon,

Le tenon ne présente donc pas de symétrie de révolution. Il peut présenter une forme section transversale droite elliptique, ovoïde, patatoïde par exemple.The tenon does not present symmetry of revolution. It may have an elliptical, ovoid, or patatoid cross-sectional shape, for example.

Alternativement, le tenon peut comporter au moins une arête pour bloquer en rotation ledit corps. Dans ce dernier cas, le tenon peut présenter une section transversale droite polygonale telle que carrée, en losange, ...

  • cette tête comprend au moins un élément de renfort mécanique de ce tenon, cet élément de renfort étant solidaire d'une part dudit fond et d'autre part dudit tenon,
Alternatively, the post may comprise at least one edge to lock said body in rotation. In the latter case, the post may have a polygonal cross-section such as square, diamond, ...
  • this head comprises at least one mechanical reinforcing element of this tenon, this reinforcing element being integral on the one hand with said bottom and on the other hand with said tenon,

De préférence, il s'agit d'une nervure de renfort.Preferably, it is a reinforcing rib.

Avantageusement, ledit au moins un élément de renfort a une forme destinée à coopérer avec ledit corps en vue de bloquer sa rotation.Advantageously, said at least one reinforcing element has a shape intended to cooperate with said body in order to block its rotation.

Cette forme peut être une nervure de renfort ayant une portion plane disposée de manière à bloquer en déplacement le corps de bouchon.

  • ledit fond comporte sur sa face recevant ledit tenon, des éléments d'accrochage formant saillie dudit fond et/ou une gorge pour renforcer l'adhérence dudit corps avec ladite tête,
This form may be a reinforcing rib having a flat portion arranged to block the plug body in displacement.
  • said bottom has on its face receiving said tenon, hooking elements projecting from said bottom and / or a groove to enhance the adhesion of said body with said head,

Ces éléments d'accrochage de dimensions longitudinales inférieures à celle du tenon, forment un relief qui vient en prise dans le corps du bouchon lors du surmoulage permettant ainsi de renforcer l'adhérence du corps de bouchon et de la tête de bouchon.These fastening elements of longitudinal dimensions smaller than that of the tenon, form a relief which engages in the body of the plug during overmoulding thus making it possible to reinforce the adhesion of the plug body and the plug head.

Le fond peut présenter sur sa face recevant le tenon, une gorge, ou rainure, continue ou non, destinée à recevoir une partie du corps de bouchon lors de l'assemblage de ce corps avec la tête de bouchon de sorte que ce corps de bouchon n'est pas seulement solidaire du tenon mais également du fond. L'accrochage du corps de bouchon et de la tête de bouchon est ainsi renforcé. Cette gorge peut à titre purement illustratif présenter la forme d'un évidement circulaire, continu ou non, entourant le tenon.

  • ledit tenon présente des aspérités pour renforcer l'adhérence dudit corps de bouchon avec ladite tête.
The bottom may have on its face receiving the tenon, groove, or groove, continuous or not, intended to receive a portion of the plug body during assembly of this body with the plug head so that the plug body is not only integral with the post but also with the bottom. The attachment of the plug body and the plug head is thus reinforced. This groove may for illustrative purposes have the form of a circular recess, continuous or not, surrounding the tenon.
  • said post has roughness to enhance the adhesion of said plug body with said head.

L'invention concerne encore un bouchon pour récipient constitué de deux matières différentes et comportant une tête de bouchon rendue solidaire d'un corps obtenu à partir d'un matériau ou d'une combinaison de matériaux moulables.The invention further relates to a container stopper made of two different materials and having a plug head secured to a body obtained from a material or a combination of moldable materials.

Selon l'invention, cette tête de bouchon est une tête telle que décrite précédemment.According to the invention, this plug head is a head as described above.

Le corps de bouchon peut ainsi être réalisé à titre d'exemple, en matière plastique alimentaire ou en résine. Ce corps de bouchon peut, en outre, être chargé en particules de liège.The stopper body can thus be made by way of example, of food plastic or resin. This plug body may, in addition, be loaded with cork particles.

Ce bouchon est notamment destiné au domaine alimentaire. De préférence, pour des spiritueux ou des vins, ce bouchon comporte un moyen de sécurisation permettant d'authentifier l'origine du produit. A titre illustratif, il peut s'agir d'un code barre ou d'une pastille comportant des particules susceptibles d'émettre une réponse à une excitation lumineuse. Ces particules sont par exemple des particules phosphorescentes qui répondent à une excitation lumineuse dans le domaine ultraviolet (UV). Ces particules peuvent être agencées sur la pastille pour représenter le signe identifiant ou individualisant tel qu'une marque, le contenu du récipient.This cap is particularly intended for the food field. Preferably, for spirits or wines, this cap comprises a security means for authenticating the origin of the product. As an illustration, it may be a bar code or a tablet comprising particles capable of emitting a response to a light excitation. These particles are, for example, phosphorescent particles which respond to a light excitation in the ultraviolet (UV) range. These particles may be arranged on the tablet to represent the identifying or identifying sign such as a mark, the contents of the container.

L'invention concerne encore un récipient tel qu'une bouteille, obturé par un bouchon tel que décrit précédemment.The invention also relates to a container such as a bottle, closed by a plug as described above.

Dans différents modes de réalisation possibles de cette tête de bouchon, l'invention sera décrite plus en détails en référence aux dessins annexés dans lesquels :

  • la figure 1 montre une vue en perspective d'une tête de bouchon selon un mode de réalisation préféré de l'invention ;
  • la figure 2 montre une autre vue en perspective de la tête de bouchon de la figure 1 ;
  • la figure 3 montre une vue de profil d'un bouchon pour récipient obtenu à partir de la tête de bouchon de la Figure 1 ;
In various possible embodiments of this plug head, the invention will be described in more detail with reference to the accompanying drawings in which:
  • the figure 1 shows a perspective view of a cap head according to a preferred embodiment of the invention;
  • the figure 2 shows another perspective view of the cap head of the figure 1 ;
  • the figure 3 shows a profile view of a container stopper obtained from the stopper head of the Figure 1 ;

Les Figures 1 et 2 montrent une tête de bouchon selon un mode de réalisation préféré de l'invention. Cette tête de bouchon 1 qui est d'un seul tenant, est réalisée ici en matière plastique.The Figures 1 and 2 show a cap head according to a preferred embodiment of the invention. This plug head 1 which is in one piece, is made here of plastic.

Cette tête de bouchon 1 est destinée à être rendue solidaire d'un corps de bouchon 2 pour former un bouchon pour récipient tel que représenté à la Figure 3.This plug head 1 is intended to be secured to a plug body 2 to form a plug for a container as shown in FIG. Figure 3 .

Cette tête 1 comprend un fond 3 formant une capsule, et un tenon 4 placé en saillie de ce fond 3. Ce tenon 4 qui est longitudinal, est destiné à coopérer avec le corps de bouchon 2 lors du surmoulage de celui-ci autour du tenon.This head 1 comprises a bottom 3 forming a capsule, and a tenon 4 projecting from the bottom 3. This pin 4 which is longitudinal, is intended to cooperate with the cap body 2 during overmolding thereof around the tenon .

Le tenon 4 comporte un unique orifice 5 débouchant latéralement de part en part du tenon de sorte que la matière plastique peut traverser le tenon 4 lors du surmoulage du corps de bouchon 2 autour de celui-ci.The stud 4 comprises a single orifice 5 opening laterally from one end of the tenon so that the plastic material can pass through the pin 4 during overmolding of the plug body 2 around it.

De plus, cet orifice 5 présente sensiblement une forme conique dans le sens longitudinal du tenon 4, sa base étant placée du côté de l'extrémité libre du tenon. Un apport de matière supplémentaire sera en conséquence présent au niveau de cette base qui est la partie du tenon 4 la plus sollicitée mécaniquement lors du retrait du bouchon d'une bouteille.In addition, this orifice 5 has a substantially conical shape in the longitudinal direction of the pin 4, its base being placed on the side of the free end of the tenon. An addition of additional material will therefore be present at this base which is the part of the post 4 most mechanically stressed when removing the cap of a bottle.

De plus, cette tête de bouchon 1 comprend des nervures de renfort 6, 7 qui sont solidaires d'une part du fond 3 et d'autre part du tenon 4. Ces nervures 6, 7 qui sont placées de part et d'autre du tenon 4 sont ici des nervures droites pour bloquer en rotation le corps de bouchon 2.In addition, this plug head 1 comprises reinforcing ribs 6, 7 which are integral on the one hand with the bottom 3 and on the other with the pin 4. These ribs 6, 7 which are placed on either side of the tenon 4 are here straight ribs for locking in rotation the plug body 2.

Le corps de bouchon 2 est réalisé avantageusement dans un élastomère thermoplastique destiné aux applications de contact alimentaire.
