摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing an ice storage container having a hard integral skin layer on the surface by water foaming. SOLUTION: The method for manufacturing the ice storage container comprises foaming a polyurethane using carbon dioxide produced through the chemical reaction of an isocyanate contained in the progenitor foaming liquid of a polyurethane with water and molding the polyurethane so as to surround a container 2. Since a molding space C is formed between the mold and the container 2 so that the side of the container 2 having higher flow resistance becomes up while the bottom part of the container 2 having lower flow resistance becomes down, the side of the container 2 is filled finally with the polyurethane. Therefore, the filling density of the polyurethane is uniform, and a hard integral skin layer is formed on the surface of the ice container, as with ice storage containers foamed with freons. The ice storage container foamed by water foaming thus requires no surface material for its surface. COPYRIGHT: (C)2010,JPO&INPIT
