Abstract

La présente invention concerne une boîte boisson à ouverture et fermeture facile, hermétique, et comportant un couvercle (20) se couplant à un corps (10) de façon à permettre l'ouverture et la fermeture. Le couvercle est formé d'une flasque inférieure (22) et d'une flasque supérieure (24). La flasque inférieure comporte un plateau à enfoncement dont la zone centrale devient convexe par déformation élastique. Une pluralité de formations en crochets (22a) dépassent à intervalles réguliers du rebord du plateau à enfoncement. Des gorges d'assemblage (24a) garnissent le pourtour de la zone basse de la flasque supérieure. Entre les formations en crochet, un rebord de la flasque inférieure est garni d'une pluralité de reliefs d'assemblage (22b) dont les extrémités supérieures sont recourbées vers l'intérieur de façon à s'emboîter dans les gorges d'assemblage de la flasque supérieure. Une fois que les gorges d'assemblage et les reliefs d'assemblage sont couplés, la flasque supérieure est solidaire de la flasque inférieure. On arrive ainsi, par déformation élastique du plateau à enfoncement de la flasque inférieure à ouvrir et refermer la boîte boisson. Ainsi, la boîte boisson peut-elle garder hermétiquement un contenu pendant l'ouverture et la fermeture du couvercle, dans la mesure où il forme une fermeture étanche par rapport au corps.
