ABSTRACT:
A method is disclosed for forming, filling and hermetically sealing a blowmolded container having a sterile integral inner dispensing outlet, all in a single sterile operation. The method is directed toward establishing a preferably hermetic seal between the inner dispensing outlet and the container neck, by establishing the seal early in the blowmolding cycle. This is accomplished by mounting the dispensing outlet-defining tubular member about a unique fluid supply mandrel. The supply mandrel thereby also serves as a check and the tubular member of the to-be-formed container serves as a tool in blowmolding. The dispensing outlet/container neck seal is thus formed before the blowmolding step.
