Abstract
A dispensing package which automatically relieves residual pressure on a cream product and dispenses this product in incremental doses is disclosed. The package uses a feed screw to drive an elevator which impels the cream product in a unidirectional manner. The drive of the feed screw is superimposed with reciprocatory motion caused by internal cams which retract the elevator. By intermittently retracting the elevator a suitable distance, discrete amounts of the product are dispensed for each cycle and the residual pressure on the product is relieved, preventing it from weeping onto the applicating surface of the dispenser. The dispensing package is well suited to contain and dispense cream deodorants and antiperspirants.
