Patent

CA 2409446

Improved pressure-applied lid (140) on cans (130) for containing drinks, with three internal annular sealing rings, two matching respectively with the beginning and end of the lid's truncated-cone shaped mouth, and a third intermediate rib, surrounded at the point where its truncated-cone shaped body passes onto the cylindrical top, by a plastic or metal ring (155) that exerts pressure in the intermediate area between the two upper annular ribs and passes inside a hook (150) made in one piece with the lid, it being thus possible, when the drinks is to be consumed, to use the fingers (160) to pull the ring (155) at a point diametrically opposite that of the hook (150) to facilitate detachment of the lid (140) from the can (130).

L'invention concerne un couvercle perfectionné (140), appliqué par pression sur des boîtes (130) destinées à contenir des boissons, et doté de trois nervures de scellement intérieures, dont deux correspondent respectivement au commencement et à la fin de l'embouchure de forme tronconique du couvercle, la troisième constituant une nervure intermédiaire entourée, à l'endroit où le corps de forme tronconique devient un sommet cylindrique, par une bague métallique ou plastique (155) qui exerce une certaine pression dans la zone intermédiaire située entre les deux nervures annulaires supérieures et passe à l'intérieur d'un crochet (150) solidaire du couvercle, de sorte qu'il est possible lors de la consommation de la boisson d'utiliser les doigts (160) pour tirer sur la bague (155) au niveau du point diamétralement opposé à celui du crochet (150), ce qui facilite le détachement du couvercle (140) à partir de la boîte-boisson.
