A plastic closure retained by snapping over bottle neck bead has a closure cap (3) with a flat closing disk (2) whose lower side (4) has an outer ring (5; 5') that surrounds the bottle neck in the closed position and an outer sealing ring (6) that lies at least in part against the inner circumference of the bottle opening and acts as a sealing cap. Both rings (5, 6) are substantially concentric to the central longitudinal axis (7) and are shaped in a single piece on the closing disk (2). On its inner side (10, 10') opposite to its sealing surface (9; 9'), the inner sealing ring (6) has several stiffening ribs (11) that extend substantially parallel to the central longitudinal axis (7). These stiffening ribs (11) are designed as shaped parts (12; 12'; 12''; 12'''; 12'''') that apply an elastic retaining pressure on at least parts of the inner sealing ring (6) in its closed position.
Un couvercle en plastique retenu sur le bourrelet du rebord d'une bouteille comprend un capuchon de fermeture (3) avec un disque plat de recouvrement (2) dont la face inférieure (4) comprend un anneau extérieur (5; 5') encerclant le col de la bouteille dans la position de fermeture et un anneau intérieur d'étanchéité (6) prenant appui au moins en partie sur la circonférence intérieure de l'ouverture de la bouteille et servant de fermeture d'étanchéité. Ces deux anneaux (5, 6) sensiblement concentriques à l'axe longitudinal médian (7) sont formés en une seule pièce sur le disque de recouvrement (2). L'anneau intérieur d'étanchéité (6) comprend, sur sa face intérieure (10, 10') opposée à sa surface d'étanchéité (9; 9'), plusieurs nervures de renforcement (11) sensiblement parallèles à l'axe longitudinal médian (7). Ces nervures de renforcement (11) se présentent formées de pièces moulées (12; 12'; 12''; 12''', 12'''') qui appliquent une pression élastique de retenue sur au moins des parties de l'anneau intérieur d'étanchéité (6) dans sa position de fermeture.
