Abstract: 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.

Abstract: The present disclosure relates to flexible, three-dimensional injection blow molded or injection stretch blow molded liners for use in overpacks, bottles, containers, etc. and methods for manufacturing the same. A method for manufacturing a liner may include injecting a polymeric material into a preform mold die to form a preform, blow molding the preform to form the liner, collapsing the liner and positioning the liner in an overpack, and inflating the liner. A fluoropolymer may be used for the preform. A liner may comprise a flexible body that substantially conforms to the interior of an overpack and a fitment port integral with the flexible body. The flexible body may be adapted to be removably inserted into the overpack by collapsing the flexible body, inserting the flexible body into the overpack, and re-inflating the flexible body inside the overpack. The flexible body may comprise a fluoropolymer and may comprise multiple layers.

Abstract: A liquid dispensing method and system for dispensing from a container including an outer container and an inner container, a portion of the inner container occupied by the liquid, a remainder of the inner container occupied by a headspace gas. The system includes a probe having a flow passage therein and a gas passage communicating between the interior of the inner container and an exterior of the outer container. Fluid (such as air or nitrogen) is caused to flow under pressure into a space between inner walls of the outer container and the inner container to force the headspace gas out of the inner container via the gas passage and to force liquid out of the inner container through the flow passage in the probe to a manufacturing process.
