<p>PURPOSE:To increase a volume of an insulating box and to improve assembling operability. CONSTITUTION:One surface 13a of a vacuum insulating panel 13 is bonded to an inner surface 10a of an outer box 10, and the other surface 13b is bonded to an outer surface 11a of an inner box 11. Since there is no gap, a pouring operation of a foamable heat insulating material 14 is facilitated, and the volume of the box 11 is increased. Fluctuations, etc., of the surfaces of the box 11 are eliminated by the direct adherence. Since the surface 13b is adhered to the surface 11a with 2-liquid main agent type adhesive, the adhesive can remain coating, adhering operability is improved, and positions of the box 11 and the panel 13 can be, after contact, corrected.</p> |
