<p>PROBLEM TO BE SOLVED: To enable easy alteration of the bulk of a container and to facilitate disposal, recycling recovery, storage, and transportation of the container by forming the container out of a shape-memory resin, also by keeping the original shape of the container at a temperature in the range of use environment, and by returning it to a crushed shape when heating it to a temperature higher than that of the use environment. SOLUTION: A bottle, for example PET bottle 1, is formed out of a shape- memory alloy. The PET bottle 1 is set so as to return to a crushed shape at, for example, approximately the temperature of remaining bath-water (approximately 40 deg.C), and it is crushed in a vertical direction or horizontal direction by being heated with remaining bath-water. Therefore, when returning the PET bottle 1 to the crushed shape it makes it possible to make the bulk of the PET bottle 1 small and facilitate disposal, recycling recovery, storage, and transportation thereof. In reuse of the PET bottle 1, it is heated and kept at a temperature in the range of use environment and thereby the bulk of the PET bottle 1 can be made large again and drink or the like can be stored therein.</p> |
