The egg tray comprises a thermoformed container 1 and a flat cardboard lid 2. On its two longitudinal edges the container has projections 12 open at the bottom, and side flanges 35 on the lid are bonded to all the outer side faces 15 of the projecting sections 12 on the same side. The egg tray thus produced has great rigidity, so that a relatively thin film material can be used to manufacture it. <IMAGE> |
