Japanese Patent JP2694183
Kind Code:
B2
Abstract:
A "thermo" box for the transportation of fresh goods, such as meat, fish, medicines or the like, comprises a double sidewall, cover and bottom construction of a thermo plastic material wherein the hollow space in the base portion, which defines the bottom of the box, 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 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 moulding, with the plastic material being extruded through a ring-shaped nozzle to a hose which is inflated and then shaped between two dies.
