Bumpy cup / Eco design

Bumpy cup
Bumpy cup

Bumpy cup gives dozens of folding to the shape of general take-out cup,
so after people drink beverage and push little bit of power, he can reduce
the volume. If people push it and reduce the volume, there is over 50%
effect in reducing volume better than the general take-out cup. It is that
trash bin and plastic trash bag can be used effectively. Also, the surface
is zigzag shape, so slip is prevented. And surface area which is touched
by hand is reduced, so delivery of cold and heat are reduced too.
Therefore, holder made by paper is not needed. Thus, it is not only reducing
the volume of trash, but also reducing the waste.
