A disperser system includes a disperser body that defines a substantially air-tight chamber therein. A sprayer assembly includes a passage, a fluid coupling, a nozzle, a valve, a valve trigger and a pouch. The passage is in fluid communication with the chamber. The valve is in fluid communication with both the passage and the fluid coupling and opens to the nozzle. The valve trigger is configured selectively to open the valve, thereby placing the passage and the fluid coupling in fluid communication with the nozzle. The pouch contains a fluid. When the chamber is charged with a gas and when the valve is opened, the gas flows through the passage and the fluid flows through the fluid coupling into the valve so that the gas entrains the fluid and delivers a suspension of the gas and the fluid to the nozzle, out of which the suspension is sprayed.

1. A disperser, comprising: (a) a disperser body;(b) a collapsible pouch containing a liquid fluid;(c) a disperser cap assembly configured to form a substantially air tight seal with the disperser body so as to define a chamber therein, the pouch disposed within the chamber and engaging the disperser cap assembly, the disperser cap assembly defining a passage in fluid communication with the chamber, the passage also in fluid communication with a valve disposed in the disperser cap assembly, the disperser cap assembly also including a coupling in fluid communication with the valve and configured to puncture a portion of the pouch so as to put the valve in fluid communication with the liquid fluid, the valve opening to a nozzle, the chamber configured to contain a gas at a pressure that is greater than ambient pressure external to the chamber so that the gas in the chamber applies a pressure to the pouch; and(d) a valve trigger configured to fluidly couple the passage and the coupling to the nozzle so that gas from the chamber flows through the passage into the nozzle and so that the liquid fluid flows into the passage and is entrained by the gas flowing through the passage, such that a gas and fluid suspension is forced out of the nozzle, the valve including an elongated valve stem that passes through the passage, the valve stem including a solid portion that blocks the passage when the solid portion is aligned with the passage, the valve stem defining a hole passing therethrough that allows gas from the chamber to pass through the passage when the hole is aligned with the passage without liquid fluid passing through the passage, the valve trigger configured to place the valve stem into a first position in which the solid portion blocks the passage so as not to allow either gas or liquid fluid to pass into the nozzle, the valve trigger also configured to place the valve stem into a a second position in which the hole is aligned with the passage so that gas from the chamber is allowed to pass through the passage without liquid fluid passing therethrough so as to clear the nozzle, the valve trigger also configured to place the valve stem into a third position in which the coupling is in fluid communication with the passage so as to allow both liquid fluid and gas from the chamber to pass into the nozzle. 2. The disperser of claim 1, wherein the fluid comprises a fluid selected from a group consisting of: an adhesive; a paint; an oil; an insecticide; a liquid; a powder; and combinations thereof. 3. The disperser of claim 1, wherein the pouch includes a bottom, a sidewall and a top, wherein the top is configured to be punctured by the coupling when the disperser cap assembly is coupled to the disperser body. 4. The disperser of claim 1, further comprising a hand pump assembly integrated with the disperser body and configured to pump air into the chamber. 5. The disperser of claim 1, further comprising a fitting in communication with the chamber and configured to allow passage of pressurized gas from a pressurized gas source into the chamber. 6. The disperser of claim 5, wherein the pressurized gas source comprises a source selected from a group consisting of: a pressurized gas cylinder; a compressed air hose from an air compressor; a portable air compressor affixed to the disperser body, and combinations thereof. 7. The disperser of claim 1, wherein the nozzle comprises a replaceable nozzle unit that fits into a nozzle fitting that is configured to accept a plurality of different nozzle types therein. 8. A disperser system, comprising: (a) a disperser body, having a top portion, defining a substantially air-tight chamber therein;(b) a sprayer assembly disposed adjacent to the top portion, the sprayer assembly including: (i) a passage in fluid communication with the chamber;(ii) a fluid coupling;(iii) a nozzle;(iv) a valve in fluid communication with both the passage and the fluid coupling and opening to the nozzle; and(v) a valve trigger configured selectively to open the valve, thereby placing the passage and the fluid coupling in fluid communication with the nozzle; and(c) a pouch configured to contain a fluid in fluid communication with the fluid coupling;wherein when the chamber is charged with a gas that has a pressure greater than ambient pressure and when the valve is opened, the gas will flow through the passage and the fluid will flow through the fluid coupling into the valve so that the gas passing through the valve entrains the fluid and delivers a suspension of the gas and the fluid to the nozzle, out of which the suspension is sprayedthe valve including an elongated valve stem that passes through the passage, the valve stem including a solid portion that blocks the passage when the solid portion is aligned with the passage, the valve stem defining a hole passing therethrough that allows gas from the chamber to pass through the passage when the hole is aligned with the passage without liquid fluid passing through the passage, the valve trigger configured to place the valve stem into a first position in which the solid portion blocks the passage so as not to allow either gas or liquid fluid to pass into the nozzle, the valve trigger also configured to place the valve stem into a a second position in which the hole is aligned with the passage so that gas from the chamber is allowed to pass through the passage without liquid fluid passing therethrough so as to clear the nozzle, the valve trigger also configured to place the valve stem into a third position in which the coupling is in fluid communication with the passage so as to allow both liquid fluid and gas from the chamber to pass into the nozzle. 9.

The disperser system of claim 8, wherein the pouch includes a bottom, a sidewall and a top, wherein the top is configured to be punctured by the coupling when the pouch is placed against the sprayer assembly. 11. The disperser system of claim 8, further comprising a hand pump assembly integrated with the disperser body and configured to pump air into the chamber. 12. The disperser system of claim 8, wherein the gas comprises a gas selected from a group consisting of: air; carbon dioxide; nitrogen; helium and combinations thereof. 13. The disperser system of claim 8, further comprising a fitting in communication with the chamber and configured to allow passage of pressurized gas from a pressurized gas source into the chamber.
