ABSTRACT:
A dispensing container including a interior barrier bag is disclosed, along with a method for filling the barrier bag with a material to be dispensed. The dispensing structure includes a non-vented pump and a dip tube structure, and a mechanism for venting the interior of the container to the atmosphere and for venting the interior of the barrier bag during filling. During assembly and filling, the barrier bag is wrapped or collapsed around the dip tube structure, so that the dip tube structure and the barrier bag can be easily inserted into a conventional container. After insertion, the barrier bag is inflated (with either an air blast or the introduction of the dispensed product) and filled with product. After filling a pump structure can be attached to the container. The method and apparatus allow a barrier bag device to be used on conventionally-designed container structures. The method and apparatus are particularly useful with containers which are made up at least partially of recycled materials.
