  • Blocking device for use with cup receptacles
    Patent number: 4300704
    Abstract: The invention relates to blocking device for use with a receptacle for cups pilable in each other. Upon discharge of the lowest cup, the next lowest cup is blocked. The blocking device is pivotable about a vertical axis and is provided with a curved surface or edge so shaped and positioned that upon the discharge of the lowest cup from the receptacle, the collar of said cup slides on the curved surface or edge and causes a rotation of the blocking device in a horizontal direction inwardly below the collar of the next lowest cup. After this occurs, a spring causes the blocking device to return to its normal position.
