  • Patent number: 5474201
    Abstract: A structure of a foot trash can is to improve the disadvantages of a conventional foot trash can which lifts up its cover vertically right above the opening of the can and easily spreads bad odor out of the trash can; the user can use his toes to press down a pedal and the pedal will push a coupling lever upward to make a rod support rotate to move the cover slidingly downward along the slope opening of the can main body to its back side so as to make the can widely open, in this way there is no air current formed and no bad odor spreaded out of the can; the opening of the can is designed to have a slope flange so that the cover may easily slide downward and make the opening of the can expose itself completely for users to throw trash easily; this can improve the disadvantage of the conventional foot trash can.
