Patent

CA 2305445

The invention provides container closure assemblies, especially for carbonated beverage containers, comprising a container neck (10) and a closure (12). A first screw thread on one of the neck (10) and the closure (12) comprises one or more first thread segments (18), and a second screw thread on the other of the neck and closure comprises a plurality of second thread segments (20). The neck and closure are constructed with a pressure safety feature that blocks unscrewing of the closure, and provides for gas venting from inside the container, when the closure (12) is at an intermediate position on the neck (10). The gas venting means includes a recess (66) located between and circumferentially overlapping two of the second thread segments (20), to increase the cross-sectional area of the vent thread path (26) through which the pressurized gas escapes at the intermediate position.

L'invention concerne des ensembles de fermeture, en particulier pour des récipients de boissons gazeuses, qui sont composés d'un goulot (10) et d'un bouchon (12). Un premier filetage situé sur l'un des éléments (10) ou bouchon (12) compte un ou plusieurs premiers segments de filet (18), et un second filetage situé sur l'autre élément goulot ou bouchon premier présente une pluralité de seconds segments de filet (20). Ce système de fermeture comporte une sécurité anti-surpression intégrée qui empêche le dévissage du bouchon et permet l'évacuation du gaz contenu dans le récipient lorsque le bouchon (12) se trouve en position intermédiaire sur le goulot (10). Cette sécurité comporte un évidement (66) situé entre deux segments de filet du second filetage (20) et chevauchant ceux-ci sur leur circonférence; cet évidement permet d'augmenter la section du passage (26) par lequel le gaz s'échappe lorsque le bouchon est en positon intermédiaire.
