A sheet metal cover for sealing the body of a beverage enabling a high internally pressurized beverage can to be formed, wherein said cover is embodied in such a way that it is possible to mount an initially separate re- sealable device. The sheet metal cover can also be configured in such a way as to maintain pressure stability. It maintains stackability and it resembles as close as possible a standard shell, at least in the external edge design thereof, such that modifications in the filling line can be kept to a minimum. The sheet metal cover is also provided with a cover panel (10) and a folding edge (11) which surrounds said panel and which is adapted such that it can be folded onto a peripheral edge of the body of the container and is suitable therefor. The panel has a large dimensioned opening (15) which is surrounded by an encircling strip (15) which is axially offset in relation to a plane (E) of the surface of the opening. A reinforcement plate (20; 21, 22, 23) extending in an extensive and radial manner is provided along at least one peripheral section of the encircling strip (16).

L'invention concerne un couvercle de tôle servant à fermer le corps d'une boîte de boisson, pour former une boîte de boisson présentant une pression interne élevée. L'objectif de cette invention est de concevoir un couvercle de tôle permettant de monter, sur ce couvercle de tôle, un dispositif refermable initialement séparé, ledit couvercle de tôle étant en outre conçu pour conserver sa résistance à la pression et sa capacité à être empilé, et de façon à ressembler le plus possible à une boîte normalisée, au moins au niveau de son contour extérieur périphérique, de sorte que les modifications à apporter à la ligne de remplissage soient aussi faibles que possible. A cet effet, le couvercle de tôle selon l'invention comporte un panneau de couvercle (10), et un bord de pliage (11) qui entoure le panneau, et qui est conçu pour être plié sur un bord périphérique du corps du contenant. Ledit panneau présente une ouverture (15) de grande dimension, qui est entourée d'une bande de pourtour (16) décalée axialement par rapport à un plan (E) de la surface de l'ouverture. Un plateau de renforcement (20, 21, 22, 23) s'étend amplement et radialement le long d'au moins une section périphérique de la bande de pourtour (16).
