  • Patent number: 8696854
    Abstract: The invention relates to a method for producing self supporting container parts, such as dishes or covers, for containers for foodstuffs to be treated in a microwave oven, said containers each comprising at least one compartment for receiving the foodstuffs, along at least part of the circumferential surface of which compartment a microwave-radiation influencing material layer is provided in the wall of at least one associated container part, comprising the steps of providing a multilayer foil comprising said microwave radiation-influencing material layer and at least one material layer that does not influence microwave radiation, which is bonded thereto on at least one side of the microwave radiation-influencing material layer, bonding one side of the multilayer foil to a remaining portion of the container part in question, in such a manner that the material layer of the multilayer foil that does not influence microwave radiation is present on a free surface of the container part.

  • Publication number: 20040084445
    Abstract: Microwaveable dish for supporting material which is to be treated in a microwave oven, in particular for foodstuffs to be prepared therein, which microwaveable dish comprises two or more compartments, a material which influences microwave radiation being incorporated in the wall of at least one of the compartments, allowing microwave radiation to be attenuated, amplified or converted into heat, and the wall comprising a plurality of layers, which microwaveable dish comprises two identical, separately prefabricated self-supporting partial containers, one of the partial containers being at least partially accommodated in the other, and in which microwaveable dish the material which influences microwave radiation is incorporated as a sheet-like material between the two partial containers.
