Abstract
(EN) In the present invention, by adding strict examination of plate thickness, pressure resistance strength is improved while responding to the need for making the plate thickness thinner. This can lid includes: a center panel section; a panel wall section; a chuck wall radius section; a chuck wall section; and a curl section. If the thickness of the center panel section is t1 and the thickness of the bottom end of the panel wall section is t2, then t2>t1.
(FR) Selon la présente invention, par l'ajout de l'examen rigoureux d'une épaisseur de plaque, une force de résistance à la pression est améliorée tout en répondant au besoin d'amincissement de l'épaisseur de plaque. Ce couvercle de canette comprend : une section panneau central; une section paroi de panneau; une section rayon de paroi de mandrin; une section paroi de mandrin; et une section recourbée. Si l'épaisseur de la section panneau central est t1 et que l'épaisseur de l'extrémité inférieure de la section paroi de panneau est t2, alors t2 > t1.
(JA) 板厚に関する厳密な検討を加えることで、板厚をより薄くする要求に応えながら、耐圧強度を向上させること。 缶蓋は、センターパネル部と、パネルウォール部と、チャックウォールラジアス部と、チャックウォール部と、カール部を有する缶蓋であって、前記センターパネル部の板厚をt1として、前記パネルウォール部下端の板厚をt2とした場合に、t2>t1である。
