Abstract
An improved structure of trashcan includes an outer can with a controllable upper cover. The upper cover has a connecting hole with a stepping part that moves downward in the outer can when being stepped. A base is at the bottom of the upper cover. First, second, third, and fourth tracks surround the stepping part at symmetrical positions of the base. Each track accommodates a restoring assembly that connects to the stepping part so that the stepping part can restore its original position after the stepping part moves to the bottom of the trashcan. The first track and the second track are stacked vertically. The third track and the fourth track are also stacked vertically. This configuration decreases the area occupied by the base. As a result, the stepping area of the stepping part is increased for the user's convenience to step on.
