Patent

CA 2435722

A crown closure (12) having a curled lower edge is described. The curled crown (12) is typically formed from double reduced steel which is 35 % thinner gauge than that used for conventional fluted crowns. The crown is also described in combination with a standard glass bottle. The curl (15) of the crown (12) tucks under the capping bead of the bottle so as to achieve standard pressure requirements. Added benefits of this configuration are not only the concealment of the edge of the closure but also the distinctive appearance of the product.

Cette invention concerne une capsule de fermeture (12) à bord inférieur ondulé. De façon générale, cette capsule (12) est réalisée dans de la tôle d'acier à double réduction dont l'épaisseur est de 35 % inférieure à celle de la tôle d'acier utilisée pour des capsules cannelées classiques. Cette capsule peut se monter sur une bouteille normale en verre. Le bord ondulé (15) de la capsule (12) se loge sous le rebord de fermeture de la bouteille, ce qui satisfait aux exigences de pression normales. Outre que son bord n'est pas apparent, cette capsule se distingue par son dessin élégant.
