<p>The tray (1) has a cavity (2) limited by a side peripheral cavity wall (3) and a cavity bottom (4), where the tray is made of polyester, polypropylene, PVC, amorphous polyethylene terephthalate or polylactic acid and is made by thermoforming a sheet of thermoformable material or by injection molding. Support pins (6a-6f) are distributed in a periphery zone (9) of the cavity bottom and project below the cavity bottom, such that the support pins carry away the cavity bottom from a support plane to a space and allowing its elastic deformation when the tray is placed on the support plane.</p> |
