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.
