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.
