DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple openable / closable container comprising a container main body and a lid externally fitted to the neck of the container main body. The present invention relates to a container that can be easily and reliably performed, has a strong fitting state of a lid body, and particularly has excellent resistance to a load from a lateral direction.

[0002]

2. Description of the Related Art A container comprising a container main body and a lid fitted to the neck of the container main body has an outer peripheral surface of the container main body and an inner peripheral surface of the lid respectively. There are a screw-type container in which a screw groove is formed and a lid is screwed onto the above-mentioned neck, and a driving-type container in which the lid is forcibly fitted to the neck of the container body. In these containers, the lid may be used as a measuring container.

[0003] However, the screw-type type requires a lot of trouble in attaching and detaching the lid, and when the contents filled in the container body are poured into the lid and used as a measuring container,
There are inconveniences such as the contents entering into the thread groove on the peripheral surface of the lid body, the contents being scattered around when the lid body is mounted again, and the contents adhering to the periphery of the container body and causing stickiness.

[0004] On the other hand, the driving type has an advantage that the attachment / detachment operation of the lid is easier than the screw type, but is inferior in resistance to overload from the lateral direction.
There is a problem that the lid is easily detached when the container is dropped. For this reason, if the lid and the container main body are strongly fitted to each other to make it difficult to remove the lid, it becomes difficult to attach / detach the lid this time, thereby impairing the merit of the drive-in type. Also,
In the case of the drive-in type, since the lid is not guided to the proper position by screwing like a screw-type container, the lid may not be mounted in the proper position, so be careful. There was a risk that the lid would come off before the contents came out, and the contents would leak out, or the contents might absorb moisture and agglomerate or deteriorate.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make it possible to easily and surely mount a cover at an appropriate position, to provide a strong fitting state of the cover, and to have an excellent resistance to a load from a lateral direction. To provide an improved container.
