In the compact container 1 having the above configuration, when the lid 20 is closed, the operating portion 41 is pushed in the pushing direction to push the disengagement member 40 inward of the container, thereby pushing the push-up piece 43 into the pedestal portion 17. It can be moved upward along the first inclined surface 17a and the second inclined surface 17b, whereby the hook portion 32 can be separated from the locking projection 31 so that the lid 20 can be opened. When the disengagement member 40 is released from being pushed after the hook portion 32 is disengaged from the locking projection 31, the disengagement member 40 is automatically returned to the initial position by the spring force of the return spring 50. When the lid body 20 is closed again, the hook portion 32 engages with the locking projection 31, and the lid body 20 is held in the closed state.

Here, in the compact container 1 of the present embodiment, a pair of support walls 60 facing each other at intervals on the support surfaces 15 are provided on both sides of the pedestal portion 17 of the container body 10, and the disengagement member 40 is provided. The slide wall 42 is held between the support surface 15 and the pair of support walls 60. That is, the disengagement member 40 is held between the support surface 15 and the pair of support walls 60 on both sides in the width direction of the pedestal portion 17. Therefore, even if a load is applied from above to the lateral portion of the operating portion 41 in the width direction in the state where the lid 20 is opened, the slide wall 42 is the support surface 15 and the support wall 60 on the side to which the load is applied. It is surely supported between the two, and the disengagement member 40 is prevented from being greatly tilted with respect to the container body 10. Therefore, as shown in FIG. 6, it is possible to prevent the disengagement member 40 from being significantly tilted with respect to the support surface 15 of the container body 10 due to the load, whereby the locking claw 44 is disengaged from the groove portion 18. It is possible to prevent the disengagement member 40 from being disengaged from the container body 10.

Further, in the compact container 1 of the present embodiment, since the pair of support walls 60 are provided so as to be integrally connected to the side surface of the pedestal portion 17, the strength of the pair of support walls 60 is increased and the lid 20 is provided. When a load is applied to the lateral portion of the operation unit 41 in the width direction from above in the open state, the support wall 60 is suppressed from being deformed by the load, and the support surface 15 and the pair of support walls are paired. The load can be reliably supported with and from 60. As a result, it is possible to more reliably prevent the locking claw 44 from coming off the groove 18 and the disengagement member 40 from coming off the container body 10.

Further, in the compact container 1 of the present embodiment, the disengagement member 40 is provided with the slide wall 42 arranged between the support surface 15 and one support wall 60, and the support surface 15 and the other support wall 60. Since the configuration has two slide walls 42 with the slide wall 42 arranged between the two, it is possible to simplify the configuration of the disengagement member 40 that exerts the above effect, and the cost of the compact container 1 can be reduced. Can be reduced.

Further, in the compact container 1 of the present embodiment, the disengagement member 40 is provided with a return spring 50 protruding from the operation portion 41 in the pushing direction between the pair of slide walls 42. The cost of the compact container 1 can be reduced by eliminating the need to provide a spring member that automatically returns the disengagement member 40 to the initial position separately from the disengagement member 40.

Further, in the compact container 1 of the present embodiment, as shown in FIGS. 4 and 5, each groove portion 18 is provided on the outer portion of the support surface 15 in the width direction from the portion facing the pair of support walls 60. I am trying to provide it. As a result, when the lid 20 is opened and a load is applied to the lateral portion of the operating portion 41 in the width direction from above, the locking claw 44 is made more difficult to disengage from the groove portion 18 and is disengaged. It is possible to more reliably prevent the member 40 from detaching from the container body 10.
