The valve arrangement also includes a second member coupled to the first member, the second member formed from another pliable material. The second member is movable from: a first position in which the second member is sealingly engaged about a periphery of the at least one aperture, thus preventing passage of a fluid through the aperture, and a second position in which at least a portion of the second member is spaced from the periphery of the aperture such that the fluid is able to pass through the aperture.
