Patent ID: 8517225

Claim:
A manually operated, personal care, rotary actuated lotion pump comprising: an accumulator capable of holding between about 30 and 1000 μL of flowable product; a hollow lower stem slidably disposed in the accumulator; a housing fixedly attached to the accumulator and having a vertical groove; an applicator head that is stationary with respect to the housing, comprising: a channel that has a lower end that is in flow communication with the accumulator through the lower stem, and a top end that has an orifice that opens onto to the exterior of the applicator head; a ring actuator comprising a raised track on an inner surface, wherein a first part of the raised track is a ramp that extends at an angle from near the top of the ring actuator to near the bottom of the ring actuator; a hollow upper stem that sits on top of the lower stem, and that has a guide that extends through the vertical groove of the housing and abuts the raised track, such that when the guide is in this first part of the track, the guide is below the ramp, such that when the ring actuator is twisted in one direction, the upper stem moves down, which downwardly displaces the lower stem into the accumulator, which forces product out of the accumulator and onto the exterior of the applicator head without moving the applicator head with respect to the housing; and when the ring actuator is twisted in the other direction, the upper stem moves up.
