The present invention relates to improvements to snap-action closures. The problem of leakage in the conventional snap-action closures is overcome by providing a resilient seal comprising an elastic gel composition between the opening and the flexible panel (2) which deforms when the flexible panel (2) is closed to create a liquid-tight seal. In particular, the gap in the region of the closure hinge (7) is closed by the elastic flow of sealant material (9) where very little, if any, closing force is otherwise exerted.
La présente invention concerne des améliorations concernant des fermetures du type bouton-pression. Le problème de fuite dans les fermetures du type bouton-pression classiques est réglé grâce à une étanchéité élastique comprenant une composition de gel élastique située entre l'ouverture et la paroi flexible (2) qui se déforme lorsque la paroi flexible (2) est fermée pour former une étanchéité par rapport aux liquides. En particulier, l'espace compris dans la zone de charnière de fermeture (7) est fermé par le courant élastique du matériau d'étanchéité (9), très peu de force de fermeture devant être exercée.
