Abstract

The invention provides a freshness retaining sealed box and belongs to the technical filed of a sealed container. The freshness retaining sealed box solves the problems of a bad sealing effect and inconvenient usage of an existing sealed box and a sealed lid. The freshness retaining sealed box includes a box body and a box lid, wherein the box lid is arranged on the box body. An inner lid is placed between the box body and the box lid. A sealing ring is positioned at the edge of the inner lid. A supporting device is arranged between the inner lid and the box cover and can make the sealing ringact on a joint position of the box body and the box lid in a sealed manner so as to make the box body and the box lid matched in a sealed manner. The freshness retaining sealed box has a reasonable and simple structure design. A flexible butting force at the flaring edge of the sealing ring can be adjusted automatically by arranging the supporting device. Elastic deformation quantity of the flaring edge of the sealing ring is automatically adjusted to make the flaring edge of the sealing ring not have elastic deformation fatigue. The sealing effect is good, and sealing is efficient while in use and the freshness retaining sealed box is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of sealed containers and relates to a fresh-keeping sealed box. Background technique [0002] When the existing sealing cover and the sealing box are sealed and matched, the rubber sealing ring is generally used for sealing and matching; the specific structure is generally as follows: an assembly position is provided at the box mouth of the sealed box, and a cover joint is provided on the sealing cover. The rubber sealing ring is embedded on the cover connection part of the sealing cover, and the sealing cover cooperates with the assembly position of the sealing box through the cover connection part, and the rubber sealing ring elastically abuts and seals between the cover connection part and the assembly position. [0003] In the above structure, the elastic contact force of the rubber sealing ring cannot be adjusted, the sealing performance of the sealing box and the sealing cover is not very good, and the...
