摘要：
A plural preform assembly (20) having nested preforms (3040) with an inner preform (40, 42, 44) and an outer preform (30, 32, 34, 44). The preforms (3040) are sealably joined together, defining a volume between the preforms (3040). Propellant (40) is disposed in the volume between the preforms (3040). The preforms (3040) are later blow molded to provide a bag (92) in bottle, bottle in bottle or similar container. The propellant (40) charge is already present when blow molded, preventing the need for a later propellant (40) filling step.
