ABSTRACT:
A thermo box (1) for the transportation of fresh goods, such as meat, fish, medicines or the like, consists of a double sidewall, cover and bottom construction of a thermoplastic material. A hollow space (7, 8, 9) in the base portion defining the bottom of the box, sidewalls and the cover is filled with air or some other gas. The basic shape of the box is a generally flat hollow moulding (2), wherein the side walls (4) are folded upwardly along weakening lines (5) and joined at their corners. An inner sheet (19) of the base portion of the box has drainage channels (24) and through holes (25) permitting ice and drainage water exuded from the moist goods to flow into the hollow space (9) in the bottom of the box, where it is trapped. The hollow moulding (2) is produced via blast moulding, wherein plastic material is extruded through a ring shaped nozzle (10) to form a hose (11), which is then inflated and shaped between two dies (15, 16).
