The invention claimed is: 1. A skin antiseptic composition dispenser comprising: a container defining an interior volume; skin antiseptic composition located within the interior volume of the container; a spout attached to the container, wherein the spout comprises at least one opening therein; a dispensing seal located between the interior volume of the container and the spout; and a foam pad located over the spout, wherein the foam pad comprises hydrophilic foam with an apparent surface energy of 35 dynes per centimeter or more; wherein the container comprises a vent opening into the interior volume of the container, wherein the vent is located remote from the foam pad; wherein the vent comprises a vent orifice and a vent seal closing the vent orifice; and wherein the vent seal comprises a barb, wherein rotation of the vent seal and the container relative to each other advances the barb to pierce the vent seal. 2. A dispenser according to claim 1, wherein the hydrophilic foam has an apparent surface energy of 40 dynes per centimeter or more. 3. A dispenser according to claim 1, wberein the hydrophilic foam has an apparent surface energy of 45 dynes per centimeter or more. 4. A dispenser according to claim 1, wherein the skin antiseptic composition comprises an agent selected from the group consisting of iodine, an iodine complex, chlorhexidine, and combinations thereof. 5. A dispenser according to claim 1, wherein the skin antiseptic composition has a surface tension of 50 dynes per centimeter or less. 6. A dispenser according to claim 1, wherein the skin antiseptic composition has a surface tension of 45 dynes per centimeter or less. 7. A dispenser according to claim 1, wherein the skin antiseptic composition has a surface tension of 40 dynes per centimeter or less. 8. A dispenser according to claim 1, wherein the container is substantially impermeable to liquid and vapor phases of the skin antiseptic composition and wherein the container exhibits permeability to gaseous ethylene oxide of 20 mg/hr/cm2 or less. 9. A dispenser according to claim 1, wherein the container comprises a tubular shape that comprises one or more flexible walls free of metallic foil layers. 10. A dispenser according to claim 9, wherein the one or more flexible walls free of metallic foil layers comprise an inner layer facing the interior volume and an outer layer facing away from the interior volume, and wherein at least one of the inner layer and the outer layer is substantially impermeable to liquid and vapor phases of the skin antiseptic composition; and further wherein at least one of the inner layer and the outer layer exhibits permeability to gaseous ethylene oxide of 20 mg/hr/cm2 or less. 11. A dispenser according to claim 10, wherein the outer layer comprises polyester. 12. A dispenser according to claim 10, wherein the inner layer is selected from the group consisting of a layer of polyolefin, a layer of halogenated polyolefin, and a layer of perfluororadical-containing thermoplastic. 13. A dispenser according to claim 1, wherein the container comprises an elongated tubular shape defining a longitudinal axis, and wherein the foam pad comprises at least one major surface, and wherein the at least one major surface is located in a plane that is not parallel to the longitudinal axis, and further wherein the longitudinal axis does not intersect the at least one major surface. 14. A dispenser according to claim 1, wherein the container comprises an elongated tubular shape defining a longitudinal axis, and wherein the foam pad comprises two opposing major surfaces, and wherein each major surface defines a plane that is not parallel to the longitudinal axis, and further wherein the longitudinal axis does not intersect at least one of the two opposing major surfaces. 15. A dispenser according to claim 14, wherein the longitudinal axis does not intersect either of the two opposing major surfaces. 16. A dispenser according to claim 1, wherein the dispensing seal comprises a seal layer attached over a dispensing orifice in the container. 17. A dispenser according to claim 1, further comprising a liquid impermeable sleeve sized to contain the foam pad, wherein the foam pad is located within the sleeve. 18. A dispenser according to claim 17, wherein the sleeve comprises a sleeve volume of 200% or more of a volume of the skin antiseptic composition in the container.
