Revolving Trash Can / Revolving Trash Can

After shopping, we may have different sizes of plastic bags remained, and families usually use them as trash bags. However, the trash bin is not able to fit all kinds of plastic bags.
In order to solve this problem, we redesign the traditional trash bin, changing it into a revolving free-fixed structure, of which the diameter can be adjusted and become suitable for different sizes of plastic bags. In this way, many discarded plastic bags can be saved and reused. This revolving trash bin is able to be unfolded into a flat, which can save space for transporting and easier to be cleaned.
