VOLUME REDUCTION DEVICE OF CONTAINER

PROBLEM TO BE SOLVED: To prevent fracture of parts such as an activated body and a container receiving body generated due to weight of an insertion bottle which the container receiving body receives so as to obtain high reliability by installing a shock absorbing means which absorbs a force of an acting means against the container receiving body when the acting means moves accompanied by an approaching action of a pair of compression bodies. SOLUTION: A shock absorbing means 55 is combined with a container receiving body 54. If weight of a bottle P applied on a receiving part 54a is less than a first weight but more than a second weight, when a cam 56 moves forward accompanied by approach of a movable compression body 52 to a fixed compression body 51, each acted body pin 83 ascends along a groove 57 inner part and a cam part 58 so that the container receiving body 54 rotates around a pivot 78. Then, the receiving part 54a is retreated downwards from the space between the compression bodies 51 and 52 and the pin 83 is escaped. If the weight of the bottle P is between the first weight and the second weight, the bottom end of the cam 56 is brought into contact with the pin 83. Furthermore, the pin 83 is pushed and an arm member 81 rotates around the pivot 78 against a spring force of a tensile coil spring 82, so as to escape the pin 83 from the cam 56.
