Abstract
An improved container, comprising, a receptacle having at least one opening; and a lid adapted to releasably cover at least a portion of the receptacle opening, comprising, one or more lower leaves having one or more ports, through which at least a portion of the receptacle opening may be accessed and having a perimeter defining a plane; one or more upper leaves, which, in a closed position, covers one or more of the ports and which, in an open position, exposes at least a portion of one or more of the ports, wherein one or more of the upper leaves, when in an open position, is adapted to return automatically to a closed position by a means for rotating about an axis which is substantially perpendicular to the plane.
Claims16
An improved container, comprising:
- a receptacle having an opening;
- a lid adapted to releasably cover at least a portion of the receptacle opening, the lid comprising a lower leaf having a port through which the receptacle opening may be accessed, and an upper leaf which, in a closed position, covers the port in the lower leaf, and which in an open position exposes at least a portion of the port, wherein the upper leaf rotates from the closed to the open position;
- a spiraling ramp fixed to the lower leaf, and engaged by a member fixed to the upper leaf, wherein the member moves up the ramp as the upper leaf is moved from the closed position to the open position, and moves down the ramp when the upper leaf is moved from the open position to the closed position.
An improved container, comprising:
- a receptacle having a circular upper edge and an opening;
- a lid adapted to releasably cover at least a portion of the receptacle opening, the lid comprising a lower leaf having a circular lower edge resting on the receptacle upper edge and defining a plane, and having a port through which the receptacle opening may be accessed, and an upper leaf which, in a closed position, covers the port in the lower leaf, and which in an open position exposes at least a portion of the port, wherein the upper leaf rotates about an axis which is substantially perpendicular to the plane, from the closed to the open position;
- a spiraling ramp fixed to the lower leaf, and engaged by a rolling wheel fixed to the upper leaf, wherein the wheel moves up the ramp as the upper leaf is moved from the closed position to the open position, and moves down the ramp when the upper leaf is moved from the open position to the closed position.
