Abstract
A sealed container lid is provided. A lid of a sealed container is provided with an open mounting recess and a one-piece moisture absorbing block is detachably mounted in the mounting recess of the lid directly. Without outer packaging, the moisture absorbing block has a large contact area with air and moisture in the sealed container is absorbed more effectively. Moreover, at least one circular deformable airtight ring is integrally formed on a surface of the lid in contact with an end surface of an opening of a container body. The deformable airtight ring is deformed due to pressure generated during fastening and thus closely attached to the end surface of the opening of the container body to form a tight seal ring. Therefore, multiple airtight seal between the lid and the container body is provided.
Claims4
A sealed container lid, comprising:
- a lid;
- and
- a moisture absorbing block disposed on the lid;
- wherein an open mounting recess is formed at a lower surface of an end surface of the lid, wherein the moisture absorbing block is a one-piece block and is mounted in the open mounting recess, wherein an elastic ring is mounted to a circumferential surface of the moisture absorbing block, and wherein at least one of an upper part and a lower part of the elastic ring is formed with a radially-projecting locking ring;
- wherein a plurality of holding members are formed to project from a surface of a peripheral wall of the open mounting recess towards a center of the open mounting recess, wherein each of the plurality of holding members is a projecting piece, and wherein a locking portion is formed at an end of each of the plurality of holding members for projecting towards the center of the open mounting recess;
- and
- wherein a shallow slot is formed at an upper surface of the end surface of the lid for being covered by a cover plate, wherein a humidity-sensitive color-changing material is mounted in a space defined by the shallow slot and the cover plate, wherein a plurality of holes are penetratingly formed through the end surface of the lid to correspond in position to the shallow slot, and thereby the open mounting recess communicates with the shallow slot through the plurality of holes.
