<p>PROBLEM TO BE SOLVED: To easily compress a container after being used, and reduce the volume, and make a space being required for the burying smaller by a method wherein on the body part of a cylindrical container main body made of a synthetic resin, a bellows part which can be compressed in the vertical direction, is formed extending to the approx. total length in the vertical direction of the container main body. SOLUTION: A bellows part 4 is formed on a body part 3 excepting the top and the bottom parts of a PET bottle-form container main body 1 in which a beverage such as juice, soft drink and sport drink, is housed. This bellows part 4 is formed extending to the approx. total length excepting the top and the bottom parts of the container main body 1, and by the existence of the bellows parts 4, the container main body 1 can be compressed in the vertical direction. This container main body 1 normally keeps the bellows part 4 stretched, and is filled with a specified amount of a beverage. Then, after the beverage in the container main body 1 has been drunk, the bellows part 4 is placed under a compressed state by depressing the container main body 1 from the top and the bottom by hands, etc., and the height of the container main body 1 itself, is decreased, and the volume is reduced.</p> |
