Description of the Related Art For example, plastic bottles used as containers for drinking water have become widely available on the market, and disposal and recycling of used PET bottles have become a problem. In particular, PET bottles are bulky if used for disposal or recycled collection as they are. For this reason, the bulk has been reduced by stepping on the foot or crushing it with a knife. However, even if you step on your feet or cut with a knife,
There is a limit to reducing the bulk of the container, and even if the user steps on the container, the container may swell, and above all, these operations for reducing the volume are laborious and troublesome.

In addition, there is also a problem that the container is bulky in storage and transportation, which hinders securing of the storage space and transportation.

る。SUMMARY OF THE INVENTION The object of the present invention is to provide a container made of a shape memory resin, which retains the original shape of the container in the operating temperature range and is heated or heated to a predetermined temperature higher than the operating temperature range. Thus, the problem is solved by a container characterized by being restored to a collapsed shape.

却するだけで、嵩の大きな容器になる。That is, the container of the present invention has solved the above-mentioned problem by utilizing the shape memory characteristics of the shape memory resin. The shape memory resin is made of, for example, a polyurethane polymer material. In this container made of a shape memory resin, it is restored to a collapsed shape having a small bulk by simply heating or heating the container to a temperature higher than the glass transition temperature higher than the operating environment temperature range. In addition, the crushed container is heated to a temperature higher than the glass transition temperature higher than the operating environment temperature range, or heated, and then deformed by sending gas or liquid into the container in that state to increase the bulk. , And just cool it into a bulky container.

きくすることができる。Therefore, when the used container is to be discarded or recycled, the container can be easily formed into a small and crushed shape without applying force. In addition, when storing or transporting an empty container that does not contain contents, the bulk of the container can be similarly easily reduced, and storage,
After transport, the bulk of the container can easily be increased to accommodate objects.

よって解決される。Another object of the present invention is to provide a shape memory resin which is softened by being heated or heated to a predetermined temperature higher than the temperature range of the use environment, deformed into a crushed shape in the softened state, and then cooled. Thus, the problem is solved by a container characterized in that the container retains its collapsed shape.

を収容しうる嵩の大きい容器になる。In other words, the container has a small bulk simply by warming or heating the container to a temperature higher than the glass transition temperature higher than the operating environment temperature range, deforming it into a crushed shape in that state, and cooling. It is kept in its collapsed shape. It is only necessary to deform the softened container into a crushed shape, and does not require much force. In addition, the collapsed container becomes a bulky container that can restore its shape by simply heating or heating to a temperature equal to or higher than the glass transition temperature higher than the use environment temperature range, and can store objects.

とができる。Therefore, the used container can be easily formed into a crushed shape having a small bulk when the container is used for disposal or recycling. By cooling after being deformed into the collapsed shape, the container retains the collapsed shape and does not swell. In addition, when storing or transporting an empty container that does not contain contents, the bulk of the container can be easily reduced similarly, and after storage and transportation, the volume of the container can be reduced.
It can be easily enlarged without force to accommodate objects.

ことができる。The container 1 shown in FIG. 1 (a) is a so-called plastic bottle containing drinking water, and FIG. 1 (b) shows the container after use after the contents are gone. This PET bottle 1 is made of a so-called shape memory resin. This plastic bottle 1
Is set to restore to a collapsed shape at a temperature of about the remaining hot water in the bath (for example, about 40 ° C.). As shown in FIG. 3 (c), the shape itself is restored to a crushed shape with a small bulk in the vertical direction. The shape may be restored to a horizontally crushed shape as shown in FIG. (D), or may be restored to various crushed shapes.
The plastic bottle 1 restored to the collapsed shape may be used for disposal or collection. There is no need to reduce the bulk by applying force, such as crushing with a foot or cutting with a knife, and the used PET bottle 1 can be formed into a crushed shape very easily with little effort.
