초록

The molded shell of an article, while still warm from being molded, and while remaining within the mold or fixture in which it has been created, for instance by blow-molding of a parison of polyolefin plastic material into contact with the mold walls, is filled with a fluid, settable foaming plastic material, for instance polyurethane. This may be done by injecting the foaming mixture directly into the cavity of the shell. In this manner time, labor and materials are saved, and the resulting product is characterized by better adhesion of the foamed core ...

1. A method for producing a molded hollow article with a filling of foamed plastic thermal insulating material, comprising: inserting a hot precursor, made of polyolefin, for a polyolefin article shell into a relatively cool mold having a mold cavity with an internal molding surface therein; conforming the hot precursor against the internal molding surface to define an article shell having an internal cavity bounded by an internal surface of the article shell; introducing through the mold and through the article shell into the internal cavity of the...
