Abstract
The present disclosure provides a container and a process for producing the container. In an embodiment, the process includes placing a sleeve bag on valve assembly (SBoV) in a blow mold apparatus. The blow mold apparatus has two opposing and movable molds. The SBoV has a valve seat. The process includes extending a parison of flowable polymeric material around the SBoV and between the opposing molds. The process includes moving the opposing molds to a closed position and pressing an upstream portion of the parison against the valve seat. The process includes blow molding a downstream portion of the parison into a container-shape within the closed mold. The process includes forming a container with the valve seat melt bonded to a neck portion of the container.
