AI Technical Summary
Technical Problem
Traditional airtight food containers use silicone sealing rings that take up space inside the container and are prone to contact with food, leading to contamination and cleaning burdens.
Method used
The box body is designed with an annular groove around the outer edge of the opening. A sealing ring is embedded in the groove and exposed outside the box. The lid makes elastic contact with the sealing ring to achieve a seal, preventing contact with food. The box body structure with the opening facing downwards is adopted to improve space utilization.
Benefits of technology
This eliminates the need for frequent cleaning of the sealing ring, improving hygiene and space utilization while reducing the user's maintenance burden.

Abstract
The sealed preservation box comprises a box body, a box cover matched with the box body and an elastic sealing ring, the box cover is of a cover body structure with a downward opening, an annular groove with a downward opening is formed in the outer edge of the opening portion of the box body in a surrounding mode, the upper portion of the sealing ring is embedded in the annular groove, and the lower portion of the sealing ring is embedded in the annular groove. And the lower part of the sealing ring is exposed out of the annular groove and is in sealing fit with the inner side wall of the box cover when the box cover covers the opening part of the box body. According to the sealed preservation box, sealing is achieved, meanwhile, the sealing ring can not make contact with food in the box, food stains are well prevented from being left on the sealing ring, the food in the box is prevented from being polluted by the sealing ring, the sealing ring does not need to be disassembled and cleaned frequently, and the maintenance burden of a user is reduced; and the edge of the box cover and the sealing ring are not located in the inner space of the box body, so that the box body can obtain larger effective volume under the same external size, food is fully loaded, and the utilization rate of the inner space of the box body is increased.
