Detachable structure of the inner cover and container provided with the detachable structure of the inner cover

Abstract

The present inventor further improves the detachable structure of the inner cover in the previous application, and proposes a structure that can eliminate unreliability in operation even in consideration of the pursuit of realistic manufacturing costs. The detachable structure of the inner cover of the present invention is such a structure, relative to the container ( 1), the outer cover (2) is used as a hand tool, and the inner cover (3) is disassembled in a bayonet snap-fit ​​shape, and it is characterized in that, especially the inner cover (3) has a The recessed portion (33) of the portion (23) is formed with a plurality of engagement protrusions (35) protruding toward the inner side of the recessed portion above it, and the pressing surface (255) of the dismounting operation portion (23) is formed to be in contact with the In the state where the inner cover (3) is engaged, the plug main body (31) of the inner cover (3) is pressed in from above, or the engaging protrusion (35) is formed so as to protrude from the tip end (351) when viewed in longitudinal section. The upper position is higher than the upper end of the plug main body (31).

Description

technical field [0001] The present invention relates to a detachable structure of an inner cover in a container including an inner cover and an outer cover, and a container provided with the detachable structure of the inner cover. Background technique [0002] In order to strictly protect the contents, a container is used that includes an inner cap that seals the opening of the container in a plug-like manner to improve airtightness, and an outer cap that is provided on the inner cap to cover the outside. In such a container, the inner lid is extremely tightly fitted into the opening in the shape of a plug, and therefore, the operation of removing and fitting the inner lid is also extremely difficult empirically. As a result, every time the inner lid is attached or detached, the contents are likely to scatter or the like. In addition, when the content is liquid, the removed inner cover often has the content attached to the bottom, and it must be placed in an upside-down po...

Problems solved by technology

[0006] That is, of course, when the inner cover is inserted in a plug state reaching the opening of the container, it is restricted by the opening of the container, and the exact size and shape appear, and the detachment operation portion of the outer cover acting on such an inner cover performs a corresponding size. Therefore, if the unreliable action caused by the previously described gap is removed, the removal of the inner cover may become reliable

However, on the other hand, the inner cover, which is opened and free, has a shape that can be said to bulge compared with the closed and closed action state, and its rigidity is not sufficient. The engaged state between becomes a state that can be said to be loose, that is, a state in which shaking is increased

In this state, if the inner cover is to be closed again, the center of the inner cover and the center of the outer cover are inconsistent, and the inner cover cannot be evenly attached to the opening, and the pressing action may not be performed reliably, or Unreliable use conditions such as the outer cover that is being pressed into the inner cover falls into the depression of the inner cover
