Description

BOUCHON DE SECURITE A VIS SCREW SECURITY PLUG
La présente invention concerne un bouchon de sécurité à vis pour le bouchage des bouteilles.The present invention relates to a screw safety cap for capping bottles.
Selon une technique d'inviolabilité connue, les bouchons à vis sont formés d'une jupe à laquelle est réunie par des pontets sécables, une bague d'inviolabilité, toute rotation de lajupe entraînant la rupture des pontets.According to a known tamper-evident technique, the screw caps are formed of a skirt to which is joined by breakable bridges, a tamper-evident ring, any rotation of the skirt causing the bridges to break.
La demanderesse s'est fixée pour objectif de créer un dispositif nouveau de bouchage dont la fonction "rupture de l'inviolabilité" devra être séparée de l'action de dévissage du bouchon.The Applicant has set itself the objective of creating a new closure device whose function "breaking of the inviolability" must be separated from the action of unscrewing the stopper.
La destruction du système attestant de l'inviolabilité devra être un acte volontaire consistant à rompre ce système en deux morceaux au minimum, et dans deux plans différents, puis à le détacher en totalité ou en partie du bouchon.The destruction of the system attesting to inviolability must be a voluntary act consisting in breaking this system into at least two pieces, and in two different planes, then detaching it in whole or in part from the cap.
De ce fait, toute réparation du système d'inviolabilité sera impossible.As a result, any repair of the inviolability system will be impossible.
En outre, le système d'inviolabilité devra être conçu pour que son remplacement par un bouchon stantard soit impossible. Avantageusement, il sera peu onéreux et adaptable sur toute une gamme de bouteilles selon le même pπncipe.In addition, the inviolability system must be designed so that its replacement by a standard cap is impossible. Advantageously, it will be inexpensive and adaptable to a whole range of bottles according to the same pπncipe.
L'emploi de deux matériaux différents dont un non-alimentaire est envisageable.The use of two different materials, one of which is non-food is possible.
Ces objectifs sont atteints grâce à l'invention qui consiste en un bouchon de sécurité à vis pour le bouchage de bouteille du type comportant un système d'inviolabilité, caractérisé en ce qu'il est constitué principalement de deux pièces concentriques, une pièce intérieure en forme de bouchon dont lajupe comporte un filetage interne destiné à s'engrener sur le filetage d'un goulot d'une bouteille, et une pièce extérieure de protection en forme de coque,celle-ci étant une coque sans toit débouchant vers le haut et vers le bas, et en ce que la coque et le bouchon sont munis de rainures verticales de géométrie telle que si on essaie de dévisser le bouchon sans enlever la coque, celle-ci tourne sans transmettre de couple. En outre, la coque comporte au moins un relief annulaire se clipsant dans une rainure externe de lajupe.These objectives are achieved thanks to the invention which consists of a screw safety cap for corking the bottle of the type comprising a tamper-evident system, characterized in that it consists mainly of two concentric parts, an inner part made of form of a cap, the skirt of which has an internal thread intended to mesh with the thread of a neck of a bottle, and an outer protective part in the form of a shell, the latter being a shell without roof opening upwards and downwards, and in that the shell and the plug are provided with vertical grooves of geometry such that if one tries to unscrew the plug without removing the shell, the latter rotates without transmitting torque. In addition, the shell has at least one annular relief which clips into an external groove of the skirt.
On comprendra mieux l'invention à l'aide de la description qui suit faite en référence aux f igures annexées suivantes : - Figure 1 : vue d'ensemble d'un bouchon conforme à l'invention vissé sur le goulot d'une bouteille et montrant la coque de protection avant rupture,The invention will be better understood using the following description made with reference to the following appended figures: - Figure 1: overall view of a stopper according to the invention screwed onto the neck of a bottle and showing the protective shell before rupture,
- Figures 2a, 2b, 2c : montrent les trois parties de la coque de protection de la f igure 1 après rupture,- Figures 2a, 2b, 2c: show the three parts of the protective shell of Figure 1 after rupture,
- Figure 3 : vue en coupe verticale de la figure 1 , - Figure 4 • vue en coupe partielle de la figure 2a montrant en coupe le talon restant en place après rupture de la coque- Figure 3: vertical sectional view of Figure 1, - Figure 4 • partial sectional view of Figure 2a showing in section the heel remaining in place after rupture of the shell
Selon le mode de réalistion représenté sur les f igures à titre d'exemple non limitatif , un bouchon de sécuπté selon l'invention est composé de deux pièces concentriques, une pièce intérieure et une pièce extérieure La pièce intérieure assurant la fonction d'étanchéité se présente sous la forme d'un bouchon à vis monomatière ( 1) à bague très basse dont la jupe (2) est munie extérieurement d'une rainure annulaire périphérique (3).According to the embodiment shown in the figures by way of nonlimiting example, a safety plug according to the invention is composed of two concentric parts, an internal part and an external part. The internal part ensuring the sealing function has the form of a single-material screw cap (1) with a very low ring, the skirt (2) of which is externally provided with a peripheral annular groove (3).
Cette pièce intérieure est réalisée en plastique ou en métal.This interior part is made of plastic or metal.
La pièce extérieure assurant la fonction de sécurité se présente sous la forme d'une coque de protection (4) en plastique sans toit. La partie inférieure de la coqueThe external part ensuring the safety function is in the form of a protective shell (4) made of plastic without roof. The lower part of the hull
(4) est bordée intérieurement d'un talon annulaire (5) de forte section clipsé dans une gorge ( 11) annulaire du goulot ( 12) de la bouteille. Le démoulage est rendu possible grâce au fait que la coque est débouchante vers le haut et le bas.(4) is internally bordered by an annular heel (5) of large section clipped into an annular groove (11) of the neck (12) of the bottle. The release is made possible thanks to the fact that the shell opens up and down.
A l'intérieur de la coque (4), un relief annulaire (6) se clipse dans la rainure (3) de lajupe du bouchon rendant solidaires les deux pièces.Inside the shell (4), an annular relief (6) clips into the groove (3) of the cap skirt making the two parts integral.
La coque et le bouchon sont munis de rainures verticales, internes (14) pour la coque et externes ( 13) pour le bouchon, dont le but est de transmettre le couple deThe shell and the plug are provided with vertical grooves, internal (14) for the shell and external (13) for the plug, the purpose of which is to transmit the torque of
\ issage de la machine. La géométrie des stries est telle que si l'on essaie de dévisser le bouchon ( 1) sans enlever la coque (4), celle-ci tourne sans transmettre de couple, guidée par le relief (6) et le talon (5). Si néanmoins le bouchon ( 1) tournait, par exemple grâce à un dispositif de pointe en acier, celui-ci provoquerait l 'éclatement de la coque (4) grâce à la dépouille du bouchon et des reliefs intérieurs de la coque.\ issage of the machine. The geometry of the ridges is such that if one tries to unscrew the plug (1) without removing the shell (4), the latter rotates without transmitting torque, guided by the relief (6) and the heel (5). If, however, the plug (1) rotated, for example by means of a steel tip device, this would cause the shell (4) to burst due to the clearance of the plug and the interior reliefs of the shell.
Deux prédécoupes (7 et 7') parallèles et prévues dans la coque (4) délimitent une languette d'arrachage (8) s'étendant d'abord depuis le bord supéπeur de la coque selon une direction parallèle à l'axe central de la coque, puis en cercle sur la périphérie de la coque selon un plan perpendiculaire audit axe central.Two precuts (7 and 7 ') parallel and provided in the shell (4) delimit a tear-off tab (8) extending first from the upper edge of the shell in a direction parallel to the central axis of the shell, then in a circle on the periphery of the shell along a plane perpendicular to said central axis.
L'arrachage de la languette (8) provoque la rupture de la coque en trois morceaux : - la languette (8),Tearing off the tongue (8) causes the shell to break into three pieces: - the tongue (8),
- une partie supéπeure (9) formant un ruban rectangulaire jetable,- an upper part (9) forming a disposable rectangular ribbon,
- une partie inférieure annulaire ( 10) correspondant sensiblement au talon (5) de la coque et restant en place dans la gorge ( 11) du goulot.- An annular lower part (10) corresponding substantially to the heel (5) of the shell and remaining in place in the groove (11) of the neck.
Les prédécoupes (7 et 7') peu\ ent être obtenues par amincissement de la paroi par micro-pont ou par micro-trou perforé mécaniquement en repπse avant ou après mise en place du bouchon ( 1) dans la coque (4).The pre-cuts (7 and 7 ') can be obtained by thinning the wall by micro-bridge or by micro-hole perforated mechanically by repπse before or after fitting the plug (1) in the shell (4).
Selon d'autres \ anantes de réalisation, non représentées, on peut prévoir deux ou plusieurs relief s (6) à l'intérieur de la coque pour coopérer avec plusieurs rainures (3) de lajupe On peut également prévoir un ou des reliefs (6) discontinus. According to other embodiments, not shown, one can provide two or more reliefs (6) inside the shell to cooperate with several grooves (3) of the skirt. One or can also provide relief (s) (6 ) discontinuous.
