Compressed Gas Dispensers

Abstract

A dispenser having a pressure vessel cartridge communicatively coupled with a chamber housing a product. The communicatively coupled pressure vessel cartridge applies a pressure to the product to displace the product from the chamber and expel the product out of a nozzle.

What is claimed is: 
     
         1 . A dispenser for applying a product to a substrate comprising:
 a housing having:
 a chamber to house a product reservoir; and 
 a pressure inlet to receive a compressed gas from a pressure vessel cartridge, 
 the product reservoir to contain the product and isolate the product from the compressed gas received from the pressure vessel cartridge; and 
   a nozzle and a valve communicatively coupled with the product reservoir,   wherein when the valve is actuated the compressed gas received from the pressure vessel cartridge displaces the product reservoir and compresses the product contained in the product reservoir to expel the product out of the nozzle.   
     
     
         2 . The dispenser according to  claim 1 , wherein the product reservoir comprises a flexible bag. 
     
     
         3 . The dispenser according to  claim 1 , wherein the product reservoir comprises a tube to contain the product and a piston being slidably disposed in the tube. 
     
     
         4 . The dispenser according to  claim 1 , wherein the product reservoir is removably housed in the chamber to provide for replacing or refilling the product reservoir. 
     
     
         5 . The dispenser according to  claim 1 , wherein the product reservoir is fixed in the chamber and irremovable from the chamber. 
     
     
         6 . The dispenser according to  claim 1 , wherein the pressure vessel cartridge is removably coupled with the pressure inlet of the chamber housing the product reservoir to provide for replacing the pressure vessel cartridge. 
     
     
         7 . The dispenser according to  claim 1 , wherein the pressure vessel cartridge comprises a disposable carbon dioxide (CO2) cartridge. 
     
     
         8 . The dispenser according to  claim 1 , further comprising a regulator arranged in a pressure path between the chamber housing the product reservoir and the pressure vessel cartridge to regulate a pressure imparted to the chamber housing the product reservoir. 
     
     
         9 . The dispenser according to  claim 8 , further comprising a safety valve arranged in the pressure path between the regulator and the chamber housing the product reservoir to prevent a pressure from being imparted to the chamber housing the product reservoir when the chamber housing the reservoir is accessed. 
     
     
         10 . A dispenser for applying a product to a substrate, the dispenser comprising:
 a housing having a pressurized gas inlet and a product outlet;   a pressure vessel cartridge containing a compressed gas coupled to the pressurized gas inlet of the housing;   a chamber containing the product, the chamber being coupled to the product outlet of the housing and to the pressurized gas inlet, the compressed gas contained in the pressure vessel cartridge to selectively impart a pressure to the chamber containing the product;   a nozzle coupled to the product outlet of the housing to dispense the product; and   a valve coupled with the chamber containing the product and actuatable to allow the product to be expelled from the chamber containing the product.   
     
     
         11 . The dispenser according to  claim 10 , further comprising a port disposed in the chamber by which to refill the chamber with the product. 
     
     
         12 . The dispenser according to  claim 10 , further comprising a top removably coupled to the housing by which to refill the chamber with the product. 
     
     
         13 . The dispenser according to  claim 10 , wherein the pressure vessel cartridge comprises a disposable carbon dioxide (CO2) cartridge. 
     
     
         14 . The dispenser according to  claim 10 , further comprising a regulator arranged in a pressure path between the chamber containing the product and the pressure vessel cartridge to regulate the pressure imparted to the chamber containing the product. 
     
     
         15 . The dispenser according to  claim 14 , further comprising a safety valve arranged in the pressure path between the regulator and the chamber containing the product to selectively prevent a pressure from being imparted to the chamber containing the product to provide for replacing or refilling the product contained in the chamber. 
     
     
         16 . A cosmetic dispenser comprising:
 a housing having a chamber and a pressurized gas inlet;   a pressure vessel cartridge containing a compressed gas coupled to the pressurized gas inlet of the housing;   a disposable reservoir containing a product, the disposable reservoir being removably received in the chamber of the housing, the compressed gas contained in the pressure vessel cartridge to impart a pressure on the disposable reservoir;   a nozzle and an actuatable valve communicatively coupled to the disposable reservoir to dispense the product; and   wherein when the actuatable valve is actuated the imparted pressure on the disposable reservoir displaces the disposable reservoir and compresses the product contained in the disposable reservoir to expel the product out of the nozzle.   
     
     
         17 . The cosmetic dispenser according to  claim 16 , wherein the disposable reservoir comprises a flexible bag. 
     
     
         18 . The cosmetic dispenser according to  claim 16 , wherein the disposable reservoir comprises a tube to contain product and a piston disposed in the tube. 
     
     
         19 . A dispenser for applying a product to a substrate, the dispenser comprising:
 a housing having a pressurized gas inlet and a product outlet;   a pressure vessel cartridge removably housed in the housing and coupled to the pressurized gas inlet of the housing;   a refillable chamber containing a product, the refillable chamber being coupled to the product outlet of the housing and coupled to the pressurized gas inlet coupled to the pressure vessel cartridge, the compressed gas contained in the pressure vessel cartridge to impart a pressure to the refillable chamber containing the product;   a nozzle coupled to the product outlet of the housing to dispense the product; and   a valve coupled with the refillable chamber containing the product and actuatable to expel the product from the refillable chamber containing the product through the nozzle.   
     
     
         20 . The dispenser according to  claim 19 , further comprising a cap removably coupled to the housing by which to replace the pressure vessel cartridge removably housed in the housing. 
     
     
         21 . The dispenser according to  claim 19 , wherein the pressure vessel cartridge comprises a disposable carbon dioxide (CO2) cartridge. 
     
     
         22 . The dispenser according to  claim 19 , further comprising a regulator arranged in a pressure path between the refillable chamber containing the product and the pressure vessel cartridge to regulate the pressure imparted to the refillable chamber containing the product. 
     
     
         23 . The dispenser according to  claim 22 , further comprising a safety valve arranged in the pressure path between the regulator and the refillable chamber containing the product to selectively prevent a pressure from being imparted to the refillable chamber containing the product to provide for refilling the product contained in the refillable chamber.
