  • it when not in use, it can be attached and stored in a refrigerator to reduce the risk of loss.
  • a customizing sticker or the like can be attached to the upper surface of the can cover to enhance marketing functionality.
  • the width of the insertion groove 241 into which the rim 11 of the can is inserted is formed to be larger than the thickness of the rim 11, so that when the size of the can is relatively small, the rim (in the inner wall in the insertion groove 241) 11) is in close contact, and if the size of the can is relatively large, the rim 11 is in close contact with the outer wall in the insertion groove 241. Therefore, it is possible to easily seal various kinds of cans regardless of the size of the cans.

Abstract

La présente invention concerne un couvercle de boîte comprenant un élément externe en forme d'anneau qui a une surface de coulissement formée au niveau de la surface périphérique interne de celui-ci; et un élément interne qui est logé rotatif dans l'élément externe, présente une partie d'insertion de boîte formée au niveau de sa surface inférieure pour permettre à un rebord faisant saillie vers le haut le long du bord de la surface supérieure d'une boîte d'être inséré dans celle-ci, et présente de multiples parties saillantes de fixation positionnées au-dessous de la partie d'insertion de boîte, guidées par la surface de coulissement pendant la rotation, et espacées mutuellement à des intervalles. Lorsque l'élément interne est positionné au niveau de la surface supérieure de la boîte, puis que l'élément externe est pivoté dans une direction, les parties saillantes de fixation se déplacent le long de la surface de coulissement pour entrer en contact avec une partie étagée formée à l'extérieur du rebord, de façon à amener ledit rebord à être étroitement disposé dans la partie d'insertion de boîte. La structure du couvercle de boîte décrite ci-dessus peut empêcher la pression d'un gaz d'acide carbonique dans la boîte de provoquer l'ouverture ou la fuite de la boîte et peut ainsi empêcher parfaitement une fuite d'un acide carbonique et également garantir l'étanchéité à l'eau. On obtient une structure compacte et réduite avec une design efficace et simple; et on peut séparer chaque composant et ainsi les laver séparément, de manière à pouvoir utiliser le couvercle de boîte dans un état propre.
