Method of forming hollow blow-molded foam articles and such hollow blow-molded foam articles

摘要

An object of the present invention is to provide a method of forming a hollow blow-molded foam (200) article and also provide such a hollow-molded foam (200) article, which are capable of improving a flow-rate efficiency of a fluid that flows through the inside of the hollow blow-molded foam (200) article. A foaming resin is sandwiched between molds (12a,12b) so that a hollow blow-molded foam (200) article having a ventilation path is molded, and a fluid for use in cooling the hollow blow-molded foam (200) article is allowed to flow through the ventilation path so that the hollow blow-molded foam (200) article is cooled.
