Abstract

L'invention porte sur un couvercle de cannette dans lequel l'épaisseur d'un matériau métallique est réduite pour permettre une diminution de la quantité de matériau métallique utilisée, lequel couvercle de cannette a une résistance à la pression améliorée pour permettre ainsi d'empêcher efficacement une fissure dans une paroi de serrage en raison d'un flambage provoqué par un impact dû à une chute ou analogues. Le couvercle de cannette, qui est constitué d'un alliage d'aluminium, comprend un cordon circulaire se projetant vers le bas à partir du rebord d'un panneau central, et une paroi de serrage et un panneau de sertissage formés au-dessus du cordon circulaire, et a un diamètre de couvercle externe de 56-63 mm et une épaisseur de 0,18-0,25 mm, la hauteur (H) depuis l'extrémité inférieure dudit cordon circulaire au panneau de sertissage étant de 7,0-7,6 mm, la hauteur (h) de la paroi externe du cordon circulaire étant égale ou inférieure à 1,0 mm et l'angle (α) de ladite paroi de serrage par rapport à la ligne axiale étant de 20-30° exclus.
