There is provided a gasket element having at least one first inner layer and at least one first outer layer. Each of the at least two layers have differing material properties. The gasket element is well suited to cooperate with an ingress/egress opening of a container that in turn is well suited to retain an active pressure and/or temperature sensitive substance. The gasket element may be operatively connected to a cap element that is suitable to selectively close the at least one ingress/egress opening of the container. The cap element may be a stand alone sealing cap or may be operatively associated with a spray nozzle or the like.

What is claimed is: 1. A gasket for sealing an opening in a container, and allowing gas within the container to vent substantially horizontally therethrough, the gasket comprising: a first substantially liquid impermeable, gas permeable and compressible layer in fluid communication with the interior of the container for allowing a flow of gas but preventing a flow of liquid therethrough and for forming a seal between the gasket and container; a second porous substantially incompressible layer defining a first side, a second side, a peripheral surface extending between the first and second sides, an interior portion extending between the first and second sides and peripheral surface, and an open cell structure forming a fluid flow path extending substantially horizontally through the interior portion in fluid communication with the first layer and the peripheral surface of the second layer; and a third compressible layer located either (i) between the first and second layers, or (ii) on an opposite side of the second layer relative to the first layer, for resiliently compressing the gasket between the container and a container closure. 2. A gasket as defined in claim 1, wherein the third layer includes a foam core located between solid outer layers. 3. A gasket as defined in claim 2, wherein the third layer includes a low density polyethylene foam core between two solid layers of polyethylene. 4. A gasket as defined in claim 1, wherein the first layer is substantially formed of at least one of PTFE and ePTFE, and the second layer is substantially formed of UHMW polyethylene. 5. A gasket as defined in claim 1, wherein the second layer defines a porosity within the range of about 10% to about 65% open area. 6. A gasket as defined in claim 1, wherein at least one of the first and second layers is coated with a substance that substantially repels the passage therethrough of at least one of a solvent, an oil and a petroleum-based substance. 7. A gasket as defined in claim 1, wherein the first layer is formed substantially of at least one of PTFE and ePTFE, the second layer is formed substantially of UHMW polyethylene, and the third layer includes a foam core located between solid outer layers. 8. A gasket as defined in claim 7, further comprising a fourth layer located on an opposite side of the third layer relative to the second layer and formed substantially of UHMW polyethylene. 9. A gasket as defined in claim 8, further comprising a fifth layer located on an opposite side of the fourth layer relative to the third layer and formed substantially of at least one of PTFE and ePTFE. 10. A gasket as defined in claim 1, wherein the third layer is located between the first and second layers. 11. A gasket as defined in claim 10, wherein the first layer is substantially formed of at least one of PTFE and ePTFE, the second layer is substantially formed of UHMW polyethylene, and the third layer is a resilient foam layer. 12. A gasket for forming a seal between a container and a container closure and permitting gas to vent substantially horizontally therethrough, the gasket comprising: first means in fluid communication with the interior of the container that is substantially liquid impermeable, gas permeable and compressible for allowing a flow of gas but preventing a flow of liquid therethrough and for forming a seal between the gasket and container; second means that is substantially incompressible including a first side, a second side, a peripheral surface extending between the first and second sides, and an interior portion extending between the first and second sides and peripheral surface, for forming a tortuous fluid flow path extending substantially horizontally through the interior portion in communication with the first means and the peripheral surface, and for venting gas substantially horizontally through the fluid flow path in the interior portion and through the peripheral surface to an exterior of the container; and third means that is compressible and is located either (i) between the first and second means, or (ii) on an opposite side of the second means relative to the first means, for resiliently compressing the gasket between the container and a container closure. 13. A gasket as defined in claim 12, wherein the first means also is for venting a gas substantially vertically therethrough. 14. A gasket as defined in claim 12, wherein the first means is a first substantially liquid impervious, compressible layer, the second means is a second porous, substantially incompressible layer, and the third means is a third compressible foam layer. 15. A gasket as defined in claim 12, wherein the third means is located between the first and second means. 16. A gasket as defined in claim 15, wherein the first means is a layer substantially formed of at least one of PTFE and ePTFE, the second means is a layer substantially formed of UHMW polyethylene, and the third means is a layer including a resilient foam core. 17. A method comprising the steps of: storing a liquid in a container including a body defining a chamber receiving therein the liquid, a container closure, and a gasket defining a porous, substantially compressible, liquid impervious first layer, a porous substantially incompressible second layer defining a first side, a second side, a peripheral surface extending between the first and second sides, an interior portion extending between the first and second sides and peripheral surface, and a tortuous fluid flow path extending through the interior portion, and a third compressible layer located either (i) between the first and second layers, or (ii) on an opposite side of the second layer relative to the first layer; interposing the gasket between the closure and the body with the gasket coupled in fluid communication between the chamber and the exterior of the container; compressing between the closure and the body the first and third layers of the gasket, but not the second layer of the gasket; forming a substantially liquid-tight seal between the compressed first layer of the gasket and the body; and venting gas from the chamber to the exterior of the container substantially horizontally through the fluid flow path extending through the interior portion of the porous substantially incompressible second layer. 18. A method as defined in claim 17, wherein the venting step includes venting gas from the chamber substantially vertically through the first layer of the gasket and into the second layer of the gasket, and venting gas in the second layer of the gasket substantially horizontally through the interior portion of the second layer and, in turn, through the peripheral surface of the second layer of the gasket to the exterior of the container. 19. A method as defined in claim 18, further comprising the step of substantially repelling the passage of liquid through the first layer of the gasket.
