Abstract

The utility model relates to a container sealing ring which is a ring body with a closed loop, wherein the cross section of the ring body is arched, a pressure relief structure is arranged on the ring body, and the pressure relief structure comprises an exhaust groove and a pressure relief sheet. Solves the problem that the container cover can not be opened due to the negative pressure formed in the container.

Description

Sealing ring for container

Technical Field

The utility model provides a container sealing ring and a container seal, and belongs to the technical field of kitchen commodities.

Background

At present, a sealing ring for a daily container in the market, in particular to a large-caliber water sealing silica gel ring structure for a pressure cooker and the like, has the condition that after liquid in the container boils, negative pressure is formed in the container after the liquid is cooled, so that a container cover body is difficult to open, and particularly, a container cover is often not opened when a woman uses the container.

Disclosure of Invention

The utility model aims to provide a container sealing ring, which is provided with a pressure relief structure, so that the problem that a container cover cannot be opened due to negative pressure formed in a container is solved.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the container sealing ring comprises a closed-loop ring body, wherein the cross section of the ring body is arched, a pressure relief structure is arranged on the ring body, and the pressure relief structure comprises an exhaust groove and a pressure relief sheet.

The pressure release structure is arranged at a concave part on the inner side of the ring body, and comprises an exhaust groove with a groove shape on the upper part of the ring body of the concave part, and pressure release sheets with two ends connected with two side walls of the concave part and the upper end connected with the inner wall of the concave part.

The pressure release sheet and the concave part form a space with an opening at the lower part.

The recess is square concave part, and its both sides wall is parallel, and the pressure release thin slice is square, and length equals the distance between the both sides wall of recess.

The ring body and the pressure release sheet are all made of silica gel.

The utility model has the advantages that: when the container is filled with liquid with higher temperature, the pressure release sheet is attached to the wall of the cover body by the air pressure in the container, so that the liquid in the container is in a completely sealed state, and leakage cannot occur. With the reduction of the temperature of the liquid in the container, the pressure in the container is reduced, the pressure release sheet is separated from the wall of the cover body, and then the pressure in the container and the pressure outside the container are balanced by exchanging the pressure release sheet with the external atmospheric pressure through the exhaust groove. When the container cover is opened (rotated), the adsorption condition does not exist, and the container cover can be normally taken down.

Detailed Description

The utility model is further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only and are not to be construed as limiting the present patent.

For the sake of brevity in describing the present embodiment, some parts of the drawings or description that are well known to those skilled in the art but not relevant to the main content of the present utility model will be omitted. In addition, some parts in the drawings may be omitted, enlarged or reduced for convenience of description, but do not represent the size or the whole structure of the actual product.

The utility model relates to a container sealing ring, as shown in fig. 1, which is a closed-loop ring body 1, wherein the cross section of the ring body 1 is arched, and a pressure relief structure is arranged on the ring body 1 and comprises a vent groove 22 and a pressure relief sheet 21.

Preferably, the pressure relief structure is arranged at a concave position 3 inside the ring body 1, as shown in fig. 2, the pressure relief structure comprises a vent groove 22 with a groove shape at the upper part of the ring body 1 of the concave position 3, and pressure relief sheets 21 with two ends connected with two side walls of the concave position 3 and the upper end connected with the inner wall of the concave position 3.

The lower end of the pressure release sheet 21 is not connected with the inner wall of the recess 3, and the pressure release sheet 21 and the recess 3 form a space with an opening at the lower part.

The recess 3 is a square recess, two side walls of the recess are parallel, the pressure release sheet 21 is square, and the length of the pressure release sheet is equal to the distance between the two side walls of the recess.

As shown in fig. 3, when the container is filled with a liquid having a relatively high temperature, the air pressure in the container is high, and the hot air enters a space with an opening at the lower part formed by the pressure release sheet 21 and the recess 3, so that the pressure release sheet 21 is attached to the cover wall 4, thereby ensuring that the liquid in the container is in a completely sealed state and no leakage occurs. As the temperature of the liquid in the container decreases, the pressure release sheet 21 is separated from the lid wall 4, and the passage between the inner wall 5 of the container and the lid wall 4 is opened, so that the interior of the container is communicated with the vent groove 22, and the pressure in the container and the pressure outside the container are balanced by exchanging the vent groove 22 with the external atmospheric pressure. Thus, when the container cover is opened (rotated), the adsorption condition is not existed, and the container cover can be normally taken down.

Preferably, both the ring body 1 and the pressure relief sheet 21 are made of silica gel.

The foregoing description is merely illustrative of the preferred embodiments of the present utility model, and is not intended to limit the scope of the present utility model. Equivalent changes and modifications are intended to be within the scope of the present utility model as defined in the appended claims.
