[0003]
[Problems to be solved by the invention]
In the case of the container, in order to prevent the vertical movement member from rotating with respect to the main tube portion, the inner surface of the storage tube portion and the outer surface of the inner tray are vertically provided with recesses and protrusions that mesh with each other. In some cases, the watertight contact with the inner plate becomes incomplete, and the liquid fluid stored in the storage cylinder portion leaks.
[0004]
In addition, by making the storage cylinder part and the inner pan slidably fitted into the storage cylinder part into a plane ellipse shape, the vertical movement member can be prevented from rotating with respect to the main cylinder part. Although the ribs and ridges are not required, the inner tray is made of an elastic synthetic resin material in order to improve water tightness with respect to the storage cylinder. For this reason, it is necessary to provide the recesses and protrusions on the inner surface of the storage cylinder and the outer surface of the inner tray.
