Description

Covered container

The present invention relates to a container containing a lid.

The conventional lidded container has a container body, an inner lid and an outer lid, wherein the container body has an opening portion; the inner lid has an elastic waterproof gasket in contact with the opening portion; and the outer lid is an elastic member. The lower surface of the outer cover of the non-elastic member is in contact with the upper surface of the inner cover, and the inner cover is pressed against the inner cover (for example, Japanese Patent Laid-Open Publication No. 2011-230807, Japanese Patent No. 4756480).

In the conventional technique, the inelastic portion under the outer cover abuts against the inelastic portion under the inner cover, and the inner cover can be pressed by the non-elastic portion to press the inner cover, and the inner cover is fixed because the size is not the same. When the outer cover is used, a gap is formed between the container main body and the outer cover. In order to control the gap to a minimum, the dimensional management must be very strict to avoid the appearance of the product due to the inconsistency of the gap.

In view of the above problems, how to design an aesthetically pleasing container without a strict dimensional management and the cover does not create a gap is a problem to be solved by the present invention.

An object of the present invention is to provide a container having a lid having a container body, an inner lid and an outer lid, wherein the container body has an opening; the inner lid has a resilient water lining in contact with the opening a mat; the outer cover has an elastic member. The outer cover is screwed with the container body, and only the air member of the inner cover is locked by the elastic member of the outer cover, thereby pressing the inner cover. Thus, the elastic member of the outer cover is pressed against the inner cover, and the elastic member is deformed, so The different sizes of the various parts, the outer cover can be connected after contact with the main body of the container, there is no gap between the outer cover and the main body of the container, the appearance is good, and water can also be stopped. In the decompressed state, the inner lid flange abuts against the upper portion of the opening of the container body, thereby determining the position of the inner lid. When the bolt is opened, only the elastic member is pressed, so the friction between the outer cover and the inner cover does not change, and the outer cover does not feel slack when the bolt is opened. The elastic member of the outer cover is detached from the upper cover, the air The inside of the container is accessed from the locked air hole, and the decompression state is easily released, so that the inner cover and the outer cover can be easily removed.

A second object of the present invention is that the amount of deformation of the elastic member is greater than that of the outer cover and the inner cover The gap can be such that the vertical movement of the inner lid can be restricted by pressurization and decompression, and the water repellency can be improved by the elastic member of the outer lid.

The third object of the present invention is that the outer diameter of the elastic water-stopping pad is larger than the container main The inner diameter of the water stopping portion of the body is larger than the gap between the outer cover and the inner cover with the elastic water stopping pad of the water stopping portion of the container body, so that the elastic member does not need to press the elastic force of the inner cover from above. The water-stopping pad can further reduce the locking force of the outer cover.

A fourth object of the present invention is another invention relating to a lidded container, the lid comprising The container has a container body, an inner lid and an outer lid, wherein the container body has an opening; the inner lid has a resilient water-stopping pad that contacts the opening; and the outer lid has an elastic member. The outer cover is screwed into the container body, and the inner cover is pressed only by the elastic member of the outer cover, and then the elastic water-stopping pad of the inner cover is pressed from above the opening of the container body, and has a structure for blocking the air hole of the inner cover. The deformation amount of the elastic water-stopping pad is larger than the gap between the outer cover and the inner cover, and is smaller than the deformation amount of the elastic member. Thus, the elastic member of the outer cover is pressed against the inner cover, and the elastic member and the elastic water-stop pad are deformed. It is not affected by the size of the diameter and the size of the upper and lower parts. Since the outer cover is not pressed by the opening, and the inner cover is only placed on the upper portion of the opening of the main body, it can be easily removed.
