What is claimed is: 1. An applicator for dispensing a fluid, comprising: a hollow elongate member comprising a container; a flange extending radially outward from said hollow elongate member; and distributor element attached to the flange, the distributor element comprising: a first side and a second side; at least two orifices; at least one projecting element rising from the first side of the distributor element; and an absorbent pad attached to the projecting element; wherein the projecting element is proximate the center of the distributor element and separates the at least two orifices such that the at least two orifices are only in fluid communication with each other on the first side of the distributor element through the absorbent pad; and wherein the projecting element comprises an orifice-free zone that avoids concentrating the fluid in the center of the absorbent pad as the fluid flows through the orifices into the absorbent pad. 2. The applicator of claim 1, wherein the orifice size is at least 0.0025 centimeters. 3. The applicator of claim 1, wherein the orifice size is less than 0.635 centimeters. 4. The applicator of claim 1, wherein the number of orifices is at least four. 5. The applicator of claim 1, wherein the projecting element comprises a raised area proximate the center of the distributor element. 6. The applicator of claim 5, wherein the raised area is a raised platform. 7. The applicator of claim 1, wherein the projecting element comprises at least one rib projecting from the first side of the distributor element. 8. The applicator of claim 1, wherein the projecting element comprises a series of interconnecting ribs that form chambers on the first side of the distributor element. 9. The applicator of claim 8, wherein the orifices are located within the chambers. 10. The applicator of claim 8, wherein the ribs form at least one chamber free of orifices. 11. The applicator of claim 1, wherein the absorbent pad is uncompressed open-cell foam. 12. The applicator of claim 1, wherein the container is collapsible. 13. The applicator of claim 1, wherein the container holds surgical prep solution. 14. The applicator of claim 13, wherein the surgical prep solution comprises a viscosity of 500 cps or less. 15. The applicator of claim 13, wherein the surgical prep solution comprises iodine. 16. The applicator of claim 1, wherein the container is substantially impermeable to ethylene oxide gas. 17. The applicator of claim 1, wherein the absorbent pad is attached to the distributor element by a seal. 18. The applicator of claim 17, wherein the seal comprises a weld such that the pad is mechanically bonded to the distributor element. 19. An applicator for dispensing a fluid, comprising: a hollow elongate member comprising a container; a flange extending radially outward from said hollow elongate member; and distributor element attached to the flange, the distributor element comprising: a first side and a second side; at least three chambers on the first side; and an absorbent material attached to at least one chamber; wherein at least two chambers each contain at least one orifice such that the at least one orifice of one chamber is only in fluid communication with the at least one orifice of the other chamber on the first side of the distributor element through the absorbent material; wherein at least one chamber proximate the center of the distributor element is free of orifices to avoid concentrating the fluid in the center of the absorbent material as the fluid flows through the orifices into the absorbent material. 20. The applicator of claim 19, wherein the number of chambers is at least four. 21. The applicator of claim 19, wherein the orifice size is at least 0.0025 centimeters. 22. The applicator of claim 19, wherein the orifice size is less than 0.635 centimeters. 23. The applicator of claim 19, wherein the number of orifices is at least four. 24. The applicator of claim 19, wherein the chambers comprise at least one rib projecting from the first side of the distributor element. 25. The applicator of claim 19, wherein the chambers comprise a series of interconnecting ribs that form chambers on the first side of the distributor element. 26. The applicator of claim 19, wherein the absorbent pad is uncompressed open-cell foam. 27. The applicator of claim 19, wherein the container is collapsible. 28. The applicator of claim 19, wherein the container holds surgical prep solution. 29. The applicator of claim 28, wherein the surgical prep solution comprises iodine. 30. The applicator of claim 19, wherein the container is substantially impermeable to ethylene oxide gas. 31. The applicator of claim 19, wherein the absorbent material is attached to the distributor element by a seal. 32. The applicator of claim 31, wherein the seal comprises a weld such that the pad is mechanically bonded to the distributor element. 33. A method of applying surgical prep solution, the method comprising: providing the applicator of claim 1, providing surgical prep solution in the container; and dispensing the surgical prep solution. 34. The method of claim 33, wherein the surgical prep solution comprises iodine and the collapsible container is substantially impermeable to ethylene oxide gas before the dispensing. 35. The method of claim 33, wherein the absorbent pad is attached to the distributor element by a seal. 36. The method of claim 35, wherein the seal comprises a weld such that the pad is mechanically bonded to the distributor element. 37. An applicator for dispensing a fluid, comprising: a hollow elongate member comprising a container; a flange extending radially outward from said hollow elongate member; and distributor element attached to the flange, the distributor element comprising: a first side and a second side; at least two orifices; a projecting element comprising a series of interconnecting ribs that form chambers on the first side of the distributor element; and an absorbent pad attached to the projecting element; wherein at least a portion the projecting element is proximate the center of the distributor element and separates the at least two orifices such that the at least two orifices are only in fluid communication with each other on the first side of the distributor element through the absorbent pad; wherein the area of each orifice is significantly smaller than the area of any chamber; and wherein the projecting element comprises an orifice-free zone that avoids concentrating the fluid in the center of the absorbent pad as the fluid flows through the orifices into the absorbent pad.
