Title (EN) BOTTLE CAPS
(FR) CAPSULES DE BOUTEILLE
Abstract:
(EN) A bottle cap for use with moulded plastics bottles which have an integral flanged seal over the aperture of a threaded neck, a frangible membrane joining the seal to the neck, the cap having a complementary screw-thread to that of the neck and at least two inwardly projecting resilient members located above the screw-thread such that, when the cap is screwed onto the bottle, the members pass around the seal with resilient deformation and, on unscrewing of the cap, engage the flanged seal in a lifting action, is characterised in that at least one, preferably two, and ideally six, of the inwardly projecting members comprises an upwardly directed blade, adapted to engage an underface of the seal so as to cut the seal, allowing its easier removal, a wall being preferably provided on the blade to reinforce the blade by acting against a side of the seal.
(FR) Capsule de bouteille destinée à être utilisée avec des bouteilles en plastique moulé dotées d'un joint à bride structurel situé sur l'ouverture d'un goulot fileté, une membrane frangible joignant le joint au goulot, la capsule comportant un filetage complémentaire à celui du goulot et au moins deux éléments souples faisant saillie vers l'intérieur, situés sur le filetage de sorte que lorsqu'on visse la capsule sur la bouteille, les éléments passent autour du joint avec une déformation élastique, et que lors du dévissage de la capsule ils entrent en contact avec le joint à bride dans un mouvement de levage. La capsule se caractérise en ce qu'au moins un, de préférence deux et idéalement six des éléments faisant saillie vers l'intérieur, comprend une lame orientée vers le haut, adaptée pour entrer en contact avec une face inférieure du joint de manière à couper celui-ci, ce qui facilite son retrait, une paroi se trouvant de préférence sur la lame afin de renforcer celle-ci en agissant contre un côté du joint.
