Dow Global Technologies LLC
Dow Global Technologies LLC, Midland, MI, patented
a container and a process to produce 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 involves moving the opposing molds to a closed
position and pressing an upstream portion of the parison
against the valve seat. The process also includes blowmolding
a downstream portion of the parison into a
container-shape within the closed mold. The last process
step incorporates forming a container with the valve seat
melt bonded to a neck portion of the container.
