Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container with a lid that is elastically inverted.

[0002]

2. Description of the Related Art Conventionally, many containers having lids that are elastically inverted are known, and a typical one is a so-called three-point hinge cap or container. The cap or the container has an appropriate gap between the cap body or the rear upper end of the container body and the rear lower end of the lid placed on the upper surface by closing the mouth formed on the upper surface thereof. And the lower ends of the inverted L-shaped elastic plates provided between the first hinges are connected to the rear part of the cap body and the like below the first hinges via the second hinges. At the same time, the other end of the elastic plate is connected to the lid upper surface portion in front of the first hinge via the third hinge.

The above-mentioned so-called three-point hinge cap or the like has a drawback in that the elastic plate is largely exposed on the outer surface of the cap or the like, which impairs the appearance.

In order to solve such drawbacks, a container body having a mouth portion on the upper surface, a lid body which is fitted on the upper surface of the container body by closing the mouth portion, and a lower end of a plate portion on the rear portion of the container body. To
And a pair of elastic connecting plates that connect the plate upper end to the rear of the lid through a pair of left and right bending portions and are parallel to each other in vertical direction, and when the lid is attached to and detached from the container body, the lower left and right bending portions are formed. The elastic connecting plate with respect to the container body, and the lid around the upper left and right bending portions as a center can be rotated by elastic inversion of the elastic connecting plate. The refraction part of the above is formed to have a taper in which the middle part rises, the left and right upper refraction parts are formed to have a taper in which the middle part falls, and the left and right refraction parts are formed to have a taper in which the middle part projects rearward. Things have been proposed.

[0005]

The above-mentioned container and the like are the same as in the case of the conventional container or cap having the three-point hinge described above.
Since a part of the hinge is formed on the top wall and the elastic plate is not exposed at the rear portion of the top wall, and the elastic connecting plate is located on the rear surface side of the container, the appearance of the container is not damaged.
In addition, since the container body or the cap body and the lid body can be separated from each other via the elastic connecting plate when the lid body is released, various effects such as the lid body not interfering with the pouring of liquid can be achieved. Although it is an excellent one that can be exhibited, there is a possibility that good elastic inversion cannot be performed unless the lateral width of each elastic plate is relatively wide due to its structure.

If the width of the elastic plate is wide, a large force is naturally required for its elastic deformation, the load applied to the thinly formed refracting portion is also increased, and the portion is easily damaged.

The present invention has been made in view of the above points, and can perform efficient elastic reversal while maintaining the advantages of the above-mentioned conventional containers and the like, and reduce the burden on the bending portion to provide more durability. The purpose is to propose a container or the like that can be used.
