Abstract
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.

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 impervious layer for forming a seal between the gasket and container;
- and
- 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 for venting gas substantially horizontally therethrough from an interior to an exterior of the container.
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 for forming a substantially liquid-tight seal between the container and the container closure;
- and
- second means fixedly secured between the first means and at least one of the container and the container closure, 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.
A method comprising the steps of:
- providing a container defining an opening and adapted to contain a substance that is at least one of pressure and temperature sensitive;
- providing a closure for closing the opening of the container;
- providing a gasket defining at least one porous, substantially compressible, liquid impervious first layer, and at least one 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 an open cell structure forming a fluid flow path extending through the interior portion;
- interposing the gasket between the closure and the opening with the gasket coupled in fluid communication between the interior and the exterior of the container;
- compressing the at least one first layer of the gasket and forming a substantially liquid-tight seal with the gasket between the interior and the exterior of the container;
- and
- venting gas from the interior to the exterior of the container substantially horizontally through the fluid flow path extending through the interior portion of the at least one porous substantially incompressible second layer.
A method comprising the following steps:
- storing a liquid that is at least one of pressure and temperature sensitive in a container including a body defining a chamber receiving therein the liquid, a container closure in fluid communication with the chamber, and a gasket including a first substantially liquid impervious layer forming a liquid-tight seal between the container closure and the container, and a second 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;
- and
- venting gas from the chamber substantially horizontally through the open cell structure of the interior portion of the second layer and, in turn, through a peripheral surface of the second layer of the gasket to the exterior of the container.
A gasket for sealing an opening in a container, and allowing gas within the container to vent therethrough, the gasket comprising:
- a first substantially liquid impervious layer for forming a seal between the gasket and container;
- and
- 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 extending substantially horizontally throughout the interior portion and forming a fluid flow path therethrough in fluid communication with the first layer and the peripheral surface of the second layer for allowing gas to vent from an interior to an exterior of the container substantially horizontally through the interior portion.
