METHOD AND APPARATUS FOR MAKING A CONTAINER COMPRISING A TRAY INTERNALLY COVERED WITH A LAYER OF THERMOPLASTIC MATERIAL
A method for making a container, wherein in a positioning step a tray (2) constituted of a single sheet of material, folded and shaped with wrinkled zones (3) is positioned in a thermoforming mould (7), and wherein in a covering step a sheet of thermoplastic material (1) is thermoformed on the tray (2), the covering step being carried out while preventing the thermoforming mould (7) from making contact with the layer of thermoplastic material (9) at the wrinkled zones (3) of an annular flange (6) of the tray (2). Also claimed is an apparatus (13) which comprises a thermoforming mould (7) in which there are present a first peripheral portion (8) configured to support in use the annular flange (6) of the tray (2) and a second peripheral portion (17) which, in the operating position, is facing the first peripheral portion (8), wherein in the operating position, the second peripheral portion (17) is at a distance from the first peripheral portion (8) in such a way that it does not make contact with the layer of thermoplastic material (9) stuck to the tray (2), at the wrinkled zones (3) of the annular flange (6).

Vacuum insulated refrigerator structure with three dimensional characteristics
A method of making a vacuum insulated refrigerator structure includes positioning a core of overlapping stacked sheets of fiberglass mat in an envelope of impermeable barrier material. The core is pressed into a predefined three dimensional shape by pressing first and second mold parts together. The core is evacuated, and the envelope is sealed to form a three dimensional core having an airtight envelope around the core. The three dimensional vacuum core is positioned between a wrapper and a liner, and the wrapper and the liner are interconnected to form a vacuum insulated refrigerator structure.
