Device for dispensing material

Abstract

A device for dispensing material comprising a pressurized container assembly, a tilt action valve connected to the container assembly, and a two-piece actuator, including a lower piece and an upper piece, where the upper piece has a discharge nozzle orifice and also a portion to be moved by a user in the single direction of the discharge orifice to open the tilt action valve and discharge the material in the single direction.

1 . A device for dispensing material, said device comprising:
 (a) a pressurized container assembly;   (b) a tilt action valve connected to said container assembly; and   (c) a two-piece actuator mechanism, including a lower piece and an upper piece, said upper piece with a discharge nozzle orifice, said upper piece having a portion to be moved by a user in a single direction of said discharge orifice to open said tilt action valve and discharge material in said direction.   
     
     
         2 . The device of  claim 1 , wherein said tilt action valve has a stem and wherein said lower piece of said actuator has a slot through which said upper piece extends to communicate with said tilt action valve stem. 
     
     
         3 . The device of  claim 1 , wherein the pressurized container assembly is a bag-in-can aerosol assembly. 
     
     
         4 . The device of  claim 1 , wherein the portion of the upper piece to be moved by a user has a surface area from about 2.0 square centimeters to about 4.0 square centimeters. 
     
     
         5 . The device of  claim 1 , wherein the viscosity of said material is from about 300 Pa-s to about 3000 Pa-s. 
     
     
         6 . The device of  claim 1 , wherein said material is a denture adhesive. 
     
     
         7 . The device of  claim 1 , wherein the angle between the length of the pressurized container assembly and the direction of the discharged material is from about 10 degrees to about 90 degrees. 
     
     
         8 . The device of  claim 1 , wherein the user may dispense the material by using one hand. 
     
     
         9 . The device of  claim 1 , further comprising a cover about said two-piece actuator. 
     
     
         10 . The device of  claim 1 , wherein said tilt action valve has a high delivery rate. 
     
     
         11 . The device of  claim 1 , wherein said two-piece actuator has an outer surface which decreases in cross section from said lower piece toward said discharge nozzle orifice. 
     
     
         12 . The device of  claim 1 , wherein said material is dispensed only in the direction that said upper piece portion is moved. 
     
     
         13 . A two-piece actuator mechanism having a longitudinal axis, including a lower piece complementary to an upper piece, said upper piece being pivotable about a single axis perpendicular to said longitudinal axis. 
     
     
         14 . The actuator of  claim 13 , wherein said upper piece has an extending portion that fits into a slot in said lower piece. 
     
     
         15 . The actuator of  claim 14 , wherein a stem of a tilt action valve protrudes through the slot of the lower piece in the opposite direction from the upper piece extending portion and fits inside the upper piece extending portion, wherein the pivoting of the upper piece opens the valve, allowing a material to dispense through the valve. 
     
     
         16 . The actuator of  claim 15 , wherein the valve is connected to a container having an inner chamber with the material to be dispensed therein and an outer chamber with propellant therein. 
     
     
         17 . The actuator of  claim 15 , wherein the material to be dispensed is a denture adhesive. 
     
     
         18 . A two-piece actuator mechanism having a longitudinal axis, including a lower piece complementary to an upper piece, said lower piece having a slot through which said upper piece extends to communicate with a stem of a tilt action valve, said actuator being pivotable about said longitudinal axis within a sector subtending 90 degrees. 
     
     
         19 . The actuator of  claim 18 , wherein said upper piece is pivotable about axes perpendicular to said longitudinal axis. 
     
     
         20 . The actuator of  claim 19 , wherein the relative motion between said upper and lower pieces opens the valve, allowing a material to flow through the valve.
