Definitions
- the present invention relates to an opening-closing device for a flexible plastic bag obtained from a film material, of the type comprising a threaded barrel attached to a wall of said bag cooperating with a plug which can be screwed onto said barrel and having teeth allowing the wall to be cut at the level of the central orifice of the barrel in order to allow the opening of said bag.
- the flexible bags concerned have, for example, been the subject, but not limited to, of the patent application in France 83 18257 also in the name of the applicant.
- the present invention proposes to remedy these drawbacks of the prior art.
- an opening-closing device for a bag of flexible synthetic material obtained from a film material of the type comprising a threaded barrel attached to a wall of said bag cooperating with a plug.
- a plug can be screwed onto said barrel and comprising teeth allowing the wall to be cut at the level of the central orifice of the barrel in order to allow the opening of said sachet, characterized in that it comprises a means made of material with the barrel and / or the stopper making it possible to protect the opposite wall of the sachet against the teeth of said stopper.
- the base of the barrel will include a cylindrical flange, of the same axis as the barrel and the stopper, the edge of which will be disposed in depth beyond the maximum position which can be reached by the teeth in the position of maximum screwing.
- the plug have a central boss projecting from the ends of the teeth.
- the device comprises a plug (1) which is screwed onto a barrel (2) by complementary threads (3,4) with interposition, before first use, of a tamper-evident ring.
- the plug (1) has teeth (5) which, during screwing, puncture the film (6) at the level of the central orifice of the barrel.
- the plug has a boss (10) projecting from the teeth (5).

Abstract
Selon une variante, l'embase (7) du fût (2) comporte une collerette (8) sensiblement cylindrique dimensionnée de manière telle que l'extrémité des dents ne puisse dépasser son chant (9).
Application : conditionnement des liquides
Description
- La présente invention a pour objet un dispositif d'ouverture-fermeture pour sachet en matière synthétique souple obtenu à partir d'un matériau en film, du type comportant un fût fileté rapporté sur une paroi dudit sachet coopérant avec un bouchon pouvant être vissé sur ledit fût et comportant des dents permettant la découpe de la paroi au niveau de l'orifice central du fût afin de permettre l'ouverture dudit sachet.
- Des dispositifs de ce type sont en eux-mêmes connus ainsi que les sachets concernés.
- Ils ont par exemple fait l'objet du brevet US 4 440 316 ainsi que des demandes de brevet en France 85 13204 et 86 09702 au nom de la demanderesse.
- Les sachets souples concernés ont par exemple fait l'objet, ceci non limitativement, de la demande de brevet en France 83 18257 également au nom de la demanderesse.
- Pour des sachets munis d'un dispositif d'ouverture-fermeture du type décrit précédemment, il y a risque en cas de manipulation mal réalisée que les dents du bouchon viennent percer la paroi opposée, ce qui vient à rendre le sachet inutilisable ultérieurement.
- La présente invention se propose de remédier à ces inconvénients de l'art antérieur.
- Conformément à l'invention, ce résultat est obtenu avec un dispositif d'ouverture-fermeture pour sachet en matière synthétique souple obtenu à partir d'un matériau en film, du type comportant un fût fileté rapporté sur une paroi dudit sachet coopérant avec un bouchon pouvant être vissé sur ledit fût et comportant des dents permettant la découpe de la paroi au niveau de l'orifice central du fût afin de permettre l'ouverture dudit sachet, caractérisé en ce qu il comporte un moyen venu de matière avec le fût et/ou le bouchon permettant de protéger la paroi opposée du sachet contre les dents dudit bouchon.
- Selon une variante de mise en oeuvre, l'embase du fût comportera une collerette cylindrique, de même axe que le fût et le bouchon, dont le chant sera disposé en profondeur au delà de la position maximale pouvant être atteinte par les dents en position de vissage maximum.
- Selon une autre variante de mise en oeuvre, le bouchon comportera un bossage central faisant saillie par rapport aux extrémités des dents.
- On comprendra mieux l'invention à l'aide de la description ci-après faite en référence aux dessins annexés dans lesquels :
- - la figure 1 est une vue en coupe longitudinale d'un bouchon utilisé dans un dispositif conforme à l'invention ;
- - la figure 2 est une vue en demi-coupe longitudinale du fût d'un dispositif conforme à l'invention ;
- - la figure 3 est une vue en demi-coupe longitudinale d'une variante d'un bouchon pour dispositif conforme à l'invention.
- On se référera tout d'abord aux figures 1 et 2.
- Le dispositif comporte un bouchon (1) qui vient se visser sur un fût (2) par des filetages complémentaires (3,4) avec interposition, avant première utilisation, d'une bague d'inviolabilité.
- Le bouchon (1) comporte des dents (5) qui lors du vissage viennent perforer le film (6) au niveau de l'orifice central du fût.
- Pour éviter de perforer la paroi opposée du sachet on peut prévoir, comme représenté à la figure 2, de munir l'embase (7) du fût d'une collerette (8) sensiblement cylindrique, coaxiale du fût et du bouchon. Elle sera dimensionnée de manière telle que l'extrémité des dents ne dépasse pas son chant (9). Cette collerette peut en outre servir de moyen de préhension pour l'utilisation lors du vissage et de la perforation.
- Dans la variante de la figure 3, le bouchon comporte un bossage (10) faisant saillie par rapport aux dents (5).
- Il interdit tout contact entre les dents et la paroi opposée.
- En outre, il permet de mettre le film (6) en pré-tension avant sa perforation, ce qui facilite celle-ci.
