Abstract

L'invention concerne un couvercle de stockage pour récipient de stockage. Le couvercle de stockage pour récipient de stockage destiné à ouvrir et fermer une ouverture formée sur un côté d'un récipient de stockage pour placer et sortir des produits stockés comprend une unité de couvercle en forme de plaque destinée à recouvrir la partie supérieure de l'ouverture et un rebord flexible s'étendant le long du bord de l'unité de couvercle dans le sens de l'épaisseur de l'unité de couvercle. Ledit rebord est fait d'un matériau élastique destiné à s'étendre de manière élastique, et à revenir vers la partie supérieure de l'unité de couvercle lorsque l'ouverture est ouverte et à revenir vers la partie inférieure de l'unité de couvercle lorsque l'ouverture est fermée de manière à entourer la circonférence extérieure de l'ouverture. Les opérations d'ouverture et de fermeture sont ainsi exécutées de manière simple afin que le couvercle de stockage puisse être facilement utilisé et qu'une force de couplage hermétique puisse être maintenue en dépit des opérations d'ouverture et de fermeture répétées.
