ABSTRACT OF THE DISCLOSURE This invention relates to packaging. The invention provides a self-supporting tray-like product container (especially for food) comprising an inner dished part receiving said product in a first well, and an outer dished part having a second well into which the 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. The spacing provides thermal and/or shock insulation and allows the inner and outer parts to be made of different materials especially ones having different thermal deformation resistances which allows use of the package in either of a conventional or microwave oven or both according to the materials chosen. The invention also provides a method and machine for making the container, including means for thermoforming the inner and outer dished parts, means for uniting one within the other, and means for filling with product and applying and sealing a cover in place.
