<p>A casing structure of freezer for container having an outside casing and an inside casing provided therebetween with a heat insulating layer that while preventing any leakage of foaming agent at the formation of the heat insulating layer, realizes shortening of working time and reduction of manufacturing cost. The flange (34) of outside casing (30) on its inside surface (30a) is provided with rib (34c) so as to lock the peripheral edge (35b) of inside casing (35) at the time of foaming of foaming agent (38) in the foaming space (V) between the outside casing (30) and the inside casing (35). At least one of the interior of the interstice between the peripheral edge (35b) of the inside casing (35) and the inside surface (30a) of the outside casing (30) and the side of foaming space (V) of the interstice is provided with sealing medium (40).</p> |
