PURPOSE:To make a container perform the easing of impact stably at the finishing end by applying a rotary damper for which the viscous drag of a liquid, etc. is utilized, as a device to ease the impact at the time of closing the lid. CONSTITUTION:An opening part 1a of a container main body 1 is opened or closed by turning of a rotary drum 2A by turning of a lid 2. To the lid 2, a rotational torque is given in the closing direction by the function of a weight 3, and the lid 2 is naturally turned and closed by simply removing hand. In this closing motion of the lid 2, a casing 9 and shaft 10 in a rotary damper 4 give relative rotations. Therefore, the lid 2 receives a damping reaction by the viscous drag, etc. of a liquid which has been filled in a filling part 12, which has been formed on the fitting-rubbing surfaces of both members 9, 18 and gives a very slow closing motion, and at the same time, the impact at the time of closing the lid 2 is eased. |
