发明名称 MOULD FOR PRODUCING SHAPED ARTICLES FROM FOAM FORMING COMPOSITIONS
摘要 A mould for use in the production of moulded articles from foam-forming compositions. The mould has a shaped mould portion into which a foam-forming composition is introduced and a closure member for closing the mould during foaming. The rim of the shaped mould portion has a lip which extends inwardly beyond the inner surface of the shaped mould portion and which is close to the closure member when the mould is closed. The lip serves to direct the gases escaping from the mould during foaming thereby substantially reducing the formation of a hard edge around the periphery of the moulded article.
