Easy-Bin / Trash Can


Most people have a habit: To discard trash when the trash heap to the top of the trash can. On this situation it is easy to trash scattered on the ground and the garbage bag may not be raised easily. So we designed a trash with retractable bottom. When we put the trash can in the ground, the bottom of the can pinch in naturally. So if the trash was higher than the can, just to pick it up and the bottom of the trash can extend by gravity, garbage will decline to the height of the edge of the can ,avoiding spattering trash in the way to take out it .Then when you pick the can again.It’s easily to pick up the bag and throw it out.
