26625-75 ABSTRACT A thermo box for the transportation of fresh goods, such as meat and fish, or of medicines or the like, consists of a double sidewall-, cover- and bottom construction of a thermo plastic material where the hollow space in the base portion, which defines the bottom of the box, the sidewalls and the cover are filled with air or some other gas. The basic shape of the box is a generally flat hollow moulding where the sidewalls are folded upwardly along weakening lines and joined at the corners. The inner sheet of the base portion of the box is supplied with drainage channels and through- going holes permitting ice- and drainage water exuded from the moist goods to flow into the hollow space in the bottom of the box where it is trapped. The hollow moulding is produced as a form of blow moulding, where the plastic material is extruded through a ring-shaped nozzle to a hose which is inflated and then shaped between two dies.
