The recess is surrounded by a land, and a peelable web is sealed to the land via a sealing arrangement so as to provide a sealed compartment. The sealing arrangement includes an inner peripheral sealing band and an outer peripheral sealing band defining therebetween an intermediate pressure dissipation channel for preserving the overall integrity of the sealing arrangement in the event of one of the sealing bands being broached.
