SUBSTANTIALLY RIGID COLLAPSIBLE LINER, CONTAINER AND/OR LINER FOR REPLACING GLASS BOTTLES, AND ENHANCED FLEXIBLE LINERS

摘要

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 systems and liners, including the liners just mentioned, that may be used as alternatives to, or replacements for, simple rigid-wall containers, such as those made of glass. Such advantageous systems and liners may replace simple rigid-wall containers in a system for delivering a high purity material to a semiconductor process substantially without modification to an end user's existing pump dispense or pressure dispense systems.
