1. A dispenser for attachment to a liquid container comprising: (a) a valve body of a generally hollow form having a liquid inlet port on one end of the valve body for coupling to the liquid container, the valve body further including an air vent opening and a liquid vent opening, the air vent opening and liquid vent opening located on an opposite side of the valve body from the inlet port;(b) a lid, the lid and valve body formed of a single piece of material, the lid movable between a liquid blocking and a liquid dispensing position;(c) a liquid seal coupled to the lid and positionable within the liquid vent opening and an air seal coupled to the lid and positionable within the air vent opening;(d) a collapsible dome member coupled to the valve body adjacent to the lid, the collapsible dome member deformable between a compressed and an expanded state. 2. The dispenser of claim 1, wherein the dome member is made of a polymer. 3. The dispenser of claim 1, wherein the dispenser is injection molded of a rigid plastic selected from a group consisting of polypropylene, polyethylene, polycarbonate and blends thereof. 4. The dispenser of claim 1, further comprising a seal sheet located on an inside surface of the valve body adjacent the liquid vent. 5. The dispenser of claim 1 wherein the seal sheet is comprised of a polymer. 6. A dispenser, comprising: (a) a generally cylindrical valve body having a liquid inlet end and an opposite end, the opposite end having a liquid outlet port and an air vent opening;(b) a lid, the lid and valve body formed of a single piece of material, the lid movable between a liquid blocking and a liquid dispensing position;(c) a liquid seal and an air seal, the liquid seal coupled to the lid and positionable within the liquid outlet port, the air seal coupled to the lid and positionable within an air vent opening; and(d) a collapsible dome member coupled to the valve body adjacent to the lid. 7. The dispenser of claim 6, wherein the liquid seal and the air seal move together to uncover the liquid outlet port and the air vent opening when the lid is depressed. 8. The dispenser of claim 6, further comprising a flaring chute proximate the liquid outlet port. 9. The dispenser of claim 6, further comprising a nozzle located adjacent to the liquid outlet port. 10. The dispenser of claim 6, wherein the valve body is coupleable to a liquid container by: gluing, rotating upon threads, snap coupling or heat welding. 11. A dispenser, comprising: (a) a valve body having a liquid inlet port on one end of the valve body and an air vent opening and liquid vent opening located on an opposite side of the valve body;(b) a lid hingedly attached to the valve body, the lid and valve body formed of a single piece of material, the lid movable between a liquid blocking and a liquid dispensing position;(c) a liquid seal and an air seal coupled to the lid, the liquid seal positionable within the liquid vent opening and the air seal positionable within the air vent opening;(d) a collapsible dome member coupled to the valve body adjacent to the lid, the collapsible dome member formed from a polymeric material and being deformable between a compressed and an expanded state. 12. The dispenser of claim 11 wherein the valve body and lid are integrally injection molded of a rigid plastic selected from a group consisting of polypropylene, polyethylene, polycarbonate and blends thereof. 13. The dispenser of claim 11, further comprising a flange member located adjacent to the liquid vent opening. 14. The dispenser of claim 11, further comprising a seal sheet located on an inside surface of the valve body adjacent the liquid vent opening. 15. The dispenser of claim 14, wherein the seal sheet is comprised of a polymer. 16. The dispenser of claim 15, wherein the seal sheet is formed from a thermoplastic elastomer. 17. The dispenser of claim 11, wherein the collapsible dome member is formed from a thermoplastic elastomer. 18. The dispenser of claim 1, wherein the collapsible dome member is formed from a thermoplastic elastomer. 19. The dispenser of claim 18, wherein the lid is hingedly attached to the valve body. 20. The dispenser of claim 19, wherein the liquid seal and lid are formed from single piece of material.
