Abstract:
A blow molding process using a captive parison for forming a container or bottle having an integral collapsible spout and a containment body, said integral collapsible spout being positioned central to said containment body and having a plurality of self latching bellow sections providing the means for said integral collapsible spout to maintain a retracted or collapsed position, and said blow molding process comprising the steps of:a) providing an elongated, tubular, formable parison between mold blocks;b) subsequently moving said mold blocks together until said mold blocks seat and establish a mold parting line, said mold blocks defining a mold cavity having a containment body mold cavity portion and a collapsible spout mold cavity portion defining said integral collapsible spout in an extended configuration,c) entrapping said parison between said mold blocks, so that said parison is positioned within the collapsible spout mold cavity portion, extending through said containment body eliminating parison flashing from said plurality of self latching bellows,d) thereafter injecting pressurized air or other gas into the interior of said parison, inflating and forcing said parison to the confines of said mold cavity in said mold blocks,e) thereby forming said container or bottle having an integral collapsible spout.
