Patent ID: 7946780

Claim:
A cosmetic dispenser comprising: (a) a brush; (b) cylinder having a first end and an operating end, an internally threaded hole passing through the operating end and operating end ratchets on an external surface of the operating end, the brush attached to the first end of the cylinder; (c) a ratchet wheel having an annular wall and an end wall, the end wall having an axial hole therethrough; the annular wall comprising internal ratchets on an internal wall and external ratchets on an external wall; the operating end of the cylinder rotatably attached to the ratchet wheel such that the ratchet wheel internal ratchets are adjacent the operating end ratchets; (i) the cylinder is rotatably attached to a revolving sleeve with the operating end and attached ratchet wheel disposed inside the revolving sleeve; (d) a piston comprising an externally threaded rod, the rod slidingly engages the ratchet wheel axial hole and the external thread of the rod threadingly engaging the operating end internally threaded hole, the rod further having a distal end attached to a piston head, the piston head is disposed in the revolving sleeve; (i) an axial tunnel extends substantially the entire length of the piston, through the rod and piston head, and communicates with the brush and a cosmetic reservoir defined by the revolving sleeve and piston head; and whereby, relative rotation of the cylinder and the rotating sleeve in a dispensing direction causes the ratchet wheel to turn the externally threaded rod and the engagement of the externally threaded rod with the internally threaded hole in the operating end, resulting in displacement of the piston head into the cosmetic reservoir and pressurized flow of a liquid cosmetic from the cosmetic reservoir through the piston axial tunnel into the brush.
