Abstract
An applicator for cream-like or gel-like compounds having an elevator in a container that is advanced toward a dome applicator head at one end of the container by turning a helical ramp that engages ramp follows attached to the elevator, the ramp having valleys therein that allow pressure that is present in the compound after a portion has been dispensed through the apertures to force the elevator away from the dome so as to relieve the pressure and prevent the formation of liquid-phase separation products from weeping through the apertures.
