Abstract

The screw-cap type bottle-stopper (1) has two self-sealing skirts, (2,3) one of which includes external rings (4) which act as scraper segments The rings make a friction contact with the internal face of the neck (7) of the bottle (6) to provide a secondary. The lower edge of the second skirt (3) may comprise a supple taper (5) which contacts an internal face (9) of the neck of the bottle (6) to provide a further seal.

Description

L'invention concerne une capsule à vis à trois niveaux d'étanchéité pour bouchage de flacon. The invention relates to a screw cap with three levels of tightness for bottle closure.

Pour assurer le bouchage des flacons en verre ou en matière plastique, on utilise couramment des capsules à vis réalisées en matière plastique telle que le polypropylène ou le polyéthylène. To ensure the closure of glass or plastic bottles, screw caps made of plastic material such as polypropylene or polyethylene are commonly used.

Les capsules sont munies d'une jupe intérieure conique qui assure une bonne étanchéité aux liquides ces capsules sont dites "à jupe auto-jointante.  The capsules are provided with a conical inner skirt which ensures good liquid tightness. These capsules are called "with self-sealing skirt.

La jupe vient se placer à ltintérieur du goulot du flacon. La coopération étroite entre la jupe souple, plastique et le rebord intérieur de bague assure chéité par rapport au produit contenu. The skirt is placed inside the neck of the bottle. The close cooperation between the flexible, plastic skirt and the inner ring rim ensures consistency with respect to the product contained.

I1 faut noter cependant que si la capsule n'est pas vissée à fond, il y a risque de fuite, la jupe n'é- tant plus parfaitement en contact. It should be noted, however, that if the cap is not fully screwed on, there is a risk of leakage, the skirt no longer being perfectly in contact.

L'objet de la présente invention est de réaliser une capsule de bouchage de flacon dont ltefficacité est nettement renforcée en ajoutant, à ltintérieur de la capsule, une seconde jupe comportant dgune part, sur sa périphérie extérieure,des joncs ou segments racleurs qui, par frottement avec la surface intérieure du gou lot,apportent un deuxieme moyen de sécurité, d'autre part, à la partie inférieure,un cône souple qui, par contact avec la surface intérieure du goulot, apporte un troi sième moyen de sécurité. The object of the present invention is to produce a bottle closure capsule whose efficiency is markedly enhanced by adding, inside the capsule, a second skirt comprising on the one hand, on its outer periphery, rods or scraping segments which, by friction with the inner surface of the gou lot, provide a second safety means, on the other hand, at the bottom, a flexible cone which, in contact with the inner surface of the neck, provides a third safety means.

La description qui suit, faite en regard du dessin annexé donné à titre d'exemple non limitatif, permettra de mieux comprendre les caractéristiques de l'invention. The following description, made with reference to the appended drawing given by way of nonlimiting example, will make it possible to better understand the characteristics of the invention.

La figure unique représente une vue partielle en coupe d'une capsule d'étanchéité conforme à
La capsule 1 munie d'une première jupe souple d'étanchéité 2 est vissée sur les filets 8 du goulot 7 du flacon 6.The single figure shows a partial sectional view of a sealing capsule according to
The capsule 1 provided with a first flexible sealing skirt 2 is screwed onto the threads 8 of the neck 7 of the bottle 6.

Elle présente une seconde jupe 3 qui porte sur sa périphérie extérieure trois joncs 4 qui, par frottement avec la surface intérieure du goulot 7, apportent un deuxième moyen d'étanchéité. It has a second skirt 3 which carries on its outer periphery three rods 4 which, by friction with the inner surface of the neck 7, provide a second sealing means.

La partie inférieure de la seconde jupe 3 forme un cane souple 5 qui, par contact avec la surface intérieure 9 du goulot 7, constitue un troisième moyen d'étanchéité
Dans une capsule de bouchage conforme à l'invention, on obtient donc trois niveaux d'étanchéité
a) par une première jupe auto-jointante,
b) par les joncs ou segments racleurs d'une seconde jupe,
c) par une zone auto-jointante à la base de cette seconde jupe.The lower part of the second skirt 3 forms a flexible cane 5 which, in contact with the internal surface 9 of the neck 7, constitutes a third sealing means
In a closure cap according to the invention, three levels of tightness are therefore obtained.
a) by a first self-sealing skirt,
b) by the rods or scraping segments of a second skirt,
c) by a self-sealing area at the base of this second skirt.

L'application de la présente invention est particulièrement destinée aux produits dits "mouillants", c' est-à-dire extrêmement pernicieux. The application of the present invention is particularly intended for so-called "wetting" products, that is to say extremely harmful.

D'autre part, au cas où la capsule est imparfaitement revissée, les joncs ou segments racleurs évitent le risque de fuite. On the other hand, if the capsule is imperfectly screwed back, the rods or scraper segments avoid the risk of leakage.

I1 est bien évident que l'on peut apporter à cette réalisation des modifications de détail dans le domaine des équivalences techniques sans, pour cela, s'écarter du cadre de la présente invention.  It is quite obvious that one can make detailed modifications to this embodiment in the field of technical equivalences without, for this, departing from the scope of the present invention.
