Title
(EN) CONTAINER AND CLOSURE WITH ANTI-MISSILING CHANNELS
(FR) RÉCIPIENT ET FERMETURE À CANAUX ANTI-PROJECTION
Abstract
(EN)
A container for pressurised liquid has a closure (V) engaged on the neck (N), both formed of yieldable polymer. The closure (V) has an end wall (21) and a skirt (20) provided with internal screw threads (24) which co-operate with external screw threads (23) on the neck to hold the closure in place. A pressure seal (25) is formed between the mouth (22) of the neck and the end wall (21) of the closure when the closure is screwed onto the neck whereby the pressurised liquid is retained within the container. To prevent missiling when the closure (V) is unscrewed the proximal face (28) of the external screw threads (23) is formed with transverse venting channels (36) extending from the base (26) of the respective screw threads to their outer extremity (27). The distal face (29) of the external screw threads (23) opposite each of the venting channels (36) is substantially continuous. This avoids weakening the neck of the container and reduces the risk of long-term creep.
(FR)
L'invention concerne un récipient pour du liquide sous pression qui a une fermeture (V) en prise sur le goulot (N), tous deux formés de polymère déformable. La fermeture (V) a une paroi d'extrémité (21) et une jupe (20) comportant des filets internes (24) qui coopèrent avec des filets externes (23) sur le goulot pour maintenir la fermeture en place. Un joint d'étanchéité (25) est formé entre l'ouverture (22) du goulot et la paroi d'extrémité (21) de la fermeture lorsque la fermeture est vissée sur le goulot, ce par quoi le liquide sous pression est retenu à l'intérieur du récipient. Pour empêcher une projection lorsque la fermeture (V) est dévissée, la face proximale (28) des filets externes (23) est formée avec des canaux d'évacuation transversaux (36) s'étendant de la base (26) des filets respectifs à leur extrémité externe (27). La face distale (29) des filets externes (23) à l'opposé de chacun des canaux d'évacuation (36) est sensiblement continue. Ceci évite d'affaiblir le goulot du récipient et réduit le risque de fluage à long terme.
