Estimating the term…
A self-supporting tray-like product container (especially for food) having an inner dished part for accommodating the product in a first well, and an outer dished part having a second well into which the first well protrudes, the inner and outer parts contacting and being joined to each other at their respective peripheral edges otherwise with their wells in all-round mutually-spaced relation. The spacing provides thermal and/or shock insulation and allows the inner and outer parts to be made of different materials especially one having different thermal deformation resistances which allows use of the package in either a conventional or a microwave oven or both according to the materials chosen.
A self supporting product container comprising an inner dished part formed with a peripheral edge portion thereabout and a first well for receiving said product, and an outer dished part formed with a peripheral edge portion thereabout and a second well into which said first well is entrant, the inner and outer parts contacting and being joined to each other at their respective peripheral edge portions, otherwise with their wells in all-round mutually-spaced relation and wherein the inner and outer dished parts are made each from a different thermoformable plastic material, said materials being selected such that one dished part has a higher resistance to thermal deformation than the other.
