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.
Claims27
A dispensing package for cream products, said dispensing package comprising:
- (a) a container body having an interior chamber of generally uniform cross section to contain said product and a lengthwise-extending central axis;
- (b) an elevator having a cross section congruent to and mounted for axial movement within said chamber;
- (c) means for axially reciprocating said elevator;
- and
- (d) means being axially rotatable for axially advancing said elevator;
- said axial rotation resulting in said axial advancement, said means for axially reciprocating said elevator and said means for axially advancing said elevator cooperating to reciprocate the elevator one cycle for each predetermined increment of forward axial advancement of the elevator by the means for axially advancing said elevator.
