Title (EN) REVERSE PRESSURE CAN END
(FR) EXTRÉMITÉ DE BOÎTE DE CONSERVE À PRESSION INVERSE
Abstract:
(EN) A can end (12) includes a center panel (14), an annular portion (16) disposed about the center panel (14), a chuck wall (18) disposed about the annular portion (16), a curl (20) extending radially outwardly from the chuck wall (18), the annular portion (16) including an annular ridge (52) and an annular countersink (52), the annular countersink (52) disposed adjacent and about the annular ridge (50). The annular countersink (52) and the annular ridge (52) are structured to resist deformation from external or reverse pressure.
(FR) Une extrémité (12) de boîte de conserve comprend un panneau central (14), une partie annulaire (16) disposée autour du panneau central (14), une paroi (18) de mandrin disposée autour de la partie annulaire (16), une boucle (20) s'étendant radialement vers l'extérieur à partir de la paroi (18) de mandrin, la partie annulaire (16) comprenant une arête annulaire (52) et une fraisure annulaire (52), la fraisure annulaire (52) étant disposée de manière adjacente et autour de la nervure annulaire (50). La fraisure annulaire (52) et la nervure annulaire (52) sont structurées pour résister à une déformation à partir d'une pression externe ou inverse.
