ABSTRACT:
An invertible pump sprayer is disclosed which enables a spray to be produced even with liquid material having viscosities as high as 100 cps. and regardless of the direction in which the spray is directed. The pump sprayer comprises a flexible container for containing the liquid material to be dispensed which collapses as the material therein is dispensed and a spray pump unit operatively associated with the flexible container. This unit includes a spray head for dispensing the material as a spray and a manually-operated pump for introducing the material to the spray head.
