DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container having a container body and a lid which are hingedly openable and closable.

[0002]

2. Description of the Related Art For example, in a compact container, as shown in FIGS. 25 and 26, a container main body 1 and a lid 2 are hinged so as to be openable and closable so that an inner plate 3 is fitted and held in the container main body 1. As a conventional container of this type, there is a container in which the inner plate 3 is adhered to the container body 11 with a double-sided adhesive tape or an adhesive. Further, as shown in FIGS. 25 and 26, a first locking portion 4 is provided at one end of the container main body 2, and one end of the inner plate 3 is moved upward at one end side of the inner plate 3 at its fitting position. The first engaging portion 5 is provided so as to be removably engaged with the first engaging portion 4 so as to regulate the position of the inner plate 3, and the second engaging portion 6 is provided on the other end side of the container body 11. On the end side, a second engaging portion 7 is provided which engages with the second engaging portion 6 from below so as to be able to be disengaged from the lower side so as to restrict the other end of the inner plate 3 from moving upward at the in-fitting position. (For example, Japanese Utility Model Publication No. 6-8813).

[0003]

However, in the conventional case,
In the case where the inner plate 3 is adhered to the container body 11 with a double-sided adhesive tape or an adhesive, the inner plate 3 cannot be easily replaced even if the contents of the inner plate 3 are lost. In addition, the first engaging portion 4, the first engaging portion 5, the second engaging portion 6, the second engaging portion 7
Is provided, the inner plate 3 is fitted inside the container body 1, the first engaging portion 5 is once engaged with the first engaging portion 4, and the second engaging portion 6 is engaged with the second engaging portion 6. When the parts 7 are engaged, it is difficult to disengage them, and in this case also, the replacement of the inner plate 3 cannot be easily performed. Therefore, it is conceivable to loosen the engagement so that the middle plate 3 can be easily replaced.
As a result, there is a problem that the engagement is easily disengaged, and the inner tray 3 is unexpectedly dropped from the container body 11.

SUMMARY OF THE INVENTION In view of the above problems, the present invention can easily and reliably hold an inner plate in an inner plate holder such as a container body, and can easily replace the inner plate.
