The present disclosure relates to an integrated liner-based system having an overpack and a liner provided within the overpack, the liner comprising a mouth and a liner wall forming an interior cavity of the liner and having a thickness such that the liner is substantially self-supporting in an expanded state, but is collapsible at a pressure of less than about 20 psi. The liner and overpack may be made by blow molding the liner and the overpack at the same time using nested preforms.

Nested blow molded liner and overpack and methods of making same

The present disclosure relates to a blow-molded, rigid collapsible liner that can be suitable particularly for smaller storage and dispensing systems. The rigid collapsible liner may be a stand-alone liner, e.g., used without an outer container, and may be dispensed from a fixed pressure dispensing can. Folds in the rigid collapsible liner may be substantially eliminated, thereby substantially reducing or eliminating the problems associated with pinholes, weld tears, and overflow. The present disclosure also relates to flexible gusseted or non-gusseted liners, which is scalable in size and may be used for storage of up to 200 L or more. The flexible gusseted liner may be foldable, such that the liner can be introduced into a dispensing can. The liner can be made of thicker materials, substantially reducing or eliminating the problems associated pinholes, and may include more robust welds, substantially reducing or eliminating the problems associated weld tears.
