<p>PROBLEM TO BE SOLVED: To enable a container to be squashed at the time of disposal of the used container by constituting a body of a variable wall face and an invariable wall part, wherein the variable wall face is connected to an invariable wall face via a rib and the variable wall face reversely rotates with the rib as an axis. SOLUTION: A container is pressed and squashed from the forward and backward sides at the time of disposal of the used container. When a variable flat wall 18a is pressed, the wall 18a rotates with a longitudinal rib 15a as an axis, while a variable side wall 19a rotates together with a longitudinal rib 16b as an axis. In addition, an upper gradient wall 20a rotates with an upper lateral rib 17a as an axis, and a lower gradient wall 21a rotates with a lower lateral rib 24a as an axis. At this time, the variable flat wall 18a is bent inward in the container to insure rotation of the variable side wall 19a, while center parts of the variable flat wall 18a and the variable side wall 19a are bent inward in a longitudinal direction to facilitate rotation of the upper and lower gradient walls 20a, 21a. Thus a volume of plastic wastes can be reduced, thereby improving transportation efficiency of the wastes.</p> |
