It comprises a substantially elastic lid (2) of silicone and a substantially rigid base (3), and includes hermetic sealing means between the lid (2) and the base (3), characterized in that said hermetic sealing means include two sealing devices, an inner device with regard to the base (3), which performs the sealing when the lid (2) expands due to the heating of the receptacle and an outer device with regard to the base (3) which performs the sealing when the lid (2) shrinks due to the cooling of the receptacle. In this way, the hermeticity between the lid (2) and the base (3) inside a conventional or microwave oven and freezer or refrigerator is achieved.
