To improve usability by locating the portion having the maximum distance from a container body at a position biased to the upper end side of the container body when a flexible handle fitted to the container body is extracted and held in a curved state.

Both upper and lower end sections of a handle are fitted to a slide fitting section 17 and a rotary fitting section 17' arranged on a container body 11, and the upper end section of a handle deformed into a curved state is locked on the lock step section 29 disposed on the slide fitting section 17. The rotation of the lower end section of the handle is regulated by a rotation regulation section 32 disposed on the rotary fitting section 17', and the upstanding angle θ2 on the lower end section side of the handle is made smaller than the upstanding angle θ1 on the upper end section side.
