Abstract
A method of post mold manufacturing a container having an integral collapsible spout molded in an extended position with flashing surrounding the integral collapsible spout. An outflow transporting means is moving the container from a blow molding machine to a trimming finishing station where flashing is removed and the container trimmed to specifications. The container is then transported to a spout collapsing station with integral collapsible spout in the molded extended position where it is compressed to a fully collapsed position. This process is completed while the material used in molding the integral collapsible spout is thermally pliable, permitting the integral collapsible spout to be transformed from the molded extended position, to the fully collapsed position.
