Further rotation of the member 6 is stopped. Further, the stop piece 18 is located in the vicinity of the adjacent release convex portion 15 when the rotation angle position of the rotating member 6 is returned by the restoring force of the elastic piece 17 due to the release of the rotation operation in the first rotation direction D1. .. Therefore, in the state where the inner container 2 is attached to the outer container 3, the range in which the rotating member 6 can rotate in the second rotation direction D2 relative to the outer container main body 5 is set within the range where the stop piece 18 and the adjacent release convex portion can be rotated. It can be regulated by contact with 15. By suppressing the floating range of the rotating member 6 in this way, it is possible to reduce the rotation operation in the first rotation direction D1 required for removing the inner container 2.

When replacing the inner container 2, the user first rotates the operation unit 21 in the first rotation direction D1 from the attached state of the inner container 2 shown in FIGS. 2A and 2B. By this rotation operation, the elastic piece 17 rides on the release convex portion 15 to push up the inner container 2 fitted with the fitting portion 19 and release the snap fitting between the snap fitting portion 19a and the inner container 2. To do. When the rotation operation is released, the rotational angle position of the rotating member 6 is returned by the restoring force of the elastic piece 17. At this time, since the position of the inner container 2 pushed up is held by the pressing fitting portion 19b, the user can easily pick up the flange 2a of the inner container 2 and take out the inner container 2 from the outer container 3. it can. When the other inner container 2 is attached, the rotation angle position of the rotating member 6 is returned as described above, so that the user simply pushes the other inner container 2 inside the outer container 3 and the fitting portion 19 Can be fitted with to complete the mounting operation.

It goes without saying that the above-described embodiment is merely an example of the embodiment of the present invention and can be variously modified without departing from the gist of the invention.
