A dispensing package for cream compositions is provided which includes a container body have a longitudinal central axis. The container body defines a storage chamber for the composition. An opening in the container body is present for discharging the composition. A fixed cam opposite the opening has teeth oriented tangentially to the longitudinal axis. A rotatable cog mounted on the cam has a plurality of ratchet teeth engageable with the teeth of the fixed cam. The cog is provided with external peripheral cams oriented parallel with the longitudinal axis. A spindle mounted on the cog extends along the central longitudinal axis between the cog and the opening. An elevator is mounted on the spindle and is displaceable between the cog and the opening to dispense the composition through the opening. A pawl is oriented transverse to the longitudinal axis and is engageable with the peripheral cams to rotate the cog and spindle on the fixed cam. An actuator button is attached to the pawl to urge the pawl against the peripheral cam. Upon actuation of the button, the cog and spindle ride on the fixed cam with a reciprocating motion which is transferred to the elevator via the spindle. |
