Description

Sealed lid closure structure

The invention relates to a sealed can technology, in particular to a closed structure of a sealed body of a sealed can.

Pressing, the sealed can comprises a container and a cover which is airtightly disposed at the opening of the container. The cover is detachably covered on the container. In order to seal the opening of the container, the bottom edge of the cover will be An annular gasket is embedded to thereby seal the periphery of the opening of the container with a gasket to achieve a sealing effect. Since this type of sealed can is easily infiltrated by liquid or powder, causing the gasket to be dirty or accumulating dirt in the gap, or even the case of mold or contamination of the food in the container, it must be frequently removed and washed, and the gasket and ring are required. After the tank is dried, it can be assembled and used, which is quite inconvenient.

In order to improve the aforementioned problems, the manufacturer developed a sealed can lid body having a handle and an elastic member. The sealed can is used to press the handle and squeeze the gasket through the elastic force of the elastic member. Pressure deformation to achieve a sealing effect; however, this type of sealed can often has problems such as uneven application and deflection during use, which leads to poor sealing effect.

In view of the above, the inventors of the present invention have made great efforts to solve the above problems in view of the above-mentioned prior art, and have made great efforts to solve the above problems, which has become the object of improvement of the present inventors.

An object of the present invention is to provide a cover closing structure for a sealed can, which is directly formed on the lower cover body through the fastening member, which not only simplifies the overall structure, is stable in operation, and has a good sealing effect.

In order to achieve the above object, the present invention provides a cover closing structure for a sealed can, for combining a container, comprising an upper cover body, a lower cover body, an elastic member and a handle member, the upper cover body including a top plate and the same a ring frame extending from the top plate, wherein the top plate is provided with a through hole, and the ring frame is formed with a stop slope; the lower cover body is disposed under the upper cover body, the lower cover body comprises a bottom plate and the bottom plate is connected a sealing ring having a fastening member extending through the through hole, wherein the fastening member is provided with a guiding structure, one end of the sealing ring is formed on an outer side of the stopping slope; the elastic component is Nested around the outer periphery of the fastening member and elastically clamped between the top plate and the bottom plate; the handle member includes a handle and an arm extending from the handle, and a body is connected to the arm. The rod system is operatively movable within the guiding structure such that the sealing ring is tightly sealed between the stop ramp and the container.

The invention also has the following effects, which are surrounded by the outer circumference of the fastening member by the ring wall, thereby improving the stability of the lower cover body during the vertical movement. The structural strength is thus enhanced by forming a plurality of ribs between the outer periphery of the lower collar and the bottom plate. By integrally forming the lower cover body and the handle member, the time required for assembly of the parts can be reduced.
