For this reason, when the volume of a waste plastic container used as a container in which contents such as beverages, food, detergents, and other daily necessities tend to remain is reduced, the reduced volume waste plastic container is banded. The contents remaining in the reduced-volume waste plastic container will decay simply by bundling and packing, giving off a bad smell during storage or transportation, or the contents leaking from the reduced-volume waste plastic container will be stored in the storage area. There is a drawback that the handling device may become dirty and the handling of the waste plastic container of reduced volume becomes complicated thereafter. Further, even during the packing operation of the waste plastic container, the contents remaining in the waste plastic container may emit a bad smell or leak out, and there is a disadvantage that the working environment is easily deteriorated.

[0004] The present invention has been made in view of the above circumstances, and when the volume of a waste plastic container used as a container in which contents easily remain is reduced, the subsequent handling is prevented from becoming complicated. Another object of the present invention is to make it possible to pack the reduced volume waste plastic container.
