Zusammenfassung: | PURPOSE:To suitably fill heat insulator by pouring liquidlike foamable resin in a space between an outer box and an inner box through a pouring hose connected to the inlet of the outer box and a plurality of discharge ports opened at the hose, and foaming the resin. CONSTITUTION:A pouring head 6 is first inserted into an inlet 5 provided at an outer box 1, and liquidlike foamable resin is poured in a space 4 interposed between an inner box 2 and a back plate 3. The resin is fluidized through a pouring hose 9 arranged along the plate 3 in a compressed state as it is, and injected to be uniformly extended from outlets 10 opened at the end and both sides of the hose 9 onto the entire back surface of the box 1. The resin is foamed to be filled in the space 4 between the boxes 1 and 2 with heat insulator 11. Thus, since the resin to be poured from the inlet 5 is guided by the hose 9, its pouring speed is not reduced during initial fluidizing. Further, the resin is injected uniformly from the outlets 10 of the hose 9 onto the entire back surface of the box 1, and smoothly foamed. |
