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.
Claims20
An invertible pump sprayer for dispensing a liquid material having a viscosity as high as 100 cps. as a fine spray regardless of the position in which the sprayer is held;
- said pump sprayer comprising a flexible inner collapsible container for containing the liquid material to be dispensed arranged within a protective rigid outer container, and a spray pump means operatively associated with said flexible container for dispensing the liquid material therein as a fine spray of individual liquid particles, without the formation of a liquid stream;
- said spray pump means including a manually-operated pump means for pumping the liquid material from said flexible container, said pump means having a pressure accumulating chamber and a pressure-actuated discharge valve for discharging liquid material from said chamber only when the pressure in the chamber is above a predetermined value, and a spray head means for atomizing the liquid material supplied by said pump means, the pump means and the pressure of the atmosphere surrounding the flexible container cooperating to collapse said flexible container and to supply sufficient liquid material under pressure to said spray head means whereby said spray head means produces said fine spray.
