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 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.

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:
A liner having a tubular body portion with a top circumferential edge and a bottom circumferential edge, a generally circular bottom portion sealed to the tubular body portion along the bottom circumferential edge, and a generally circular top portion sealed to the tubular body portion along the top circumferential edge. The top portion may include a fitment sealed thereto. The tubular body portion may include at least one weld seam extending from the top circumferential edge to the bottom circumferential edge. In a particular embodiment, the tubular body portion may include two sheets welded together to form a tubular body, the tubular body portion thus having two weld seams extending from the top circumferential edge to the bottom circumferential edge.

Abstract:
A pressure dispense method and system for reducing the presence of folds for a liquid-filled liner within an overpack while reducing the loads and stresses on the liquid-filled liner. The flexible liner is of a conformal size and shape to the interior space of the overpack so that the flexible liner does not pull downward and away from the interior surface of the overpack when the flexible liner is filled with a liquid. The flexible liner also configured to eliminate folding in upon itself when the liner is filled with a liquid within the overpack.
Abstract:
THE PRESENT DISCLOSURE RELATES TO A BLOW-MOLDED, RIGID COLLAPSIBLE LINER (600) 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 (610) 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 a liner comprising at least two liner panels welded together along edges of the panels forming an interior cavity of the liner, the interior cavity having substantially no perpendicular joints.
Abstract:
The present disclosure, in one embodiment, relates to a liner-based assembly having an overpack and a liner disposed within the overpack. The liner may be formed by blow molding a liner preform within the overpack to form a blow molded liner substantially conforming to the interior of the overpack and generally forming an interface with an interior of the overpack. The present disclosure, in another embodiment, relates to a liner-based assembly including a blow-molded overpack comprised of polyethylene terephthalate, a blow-molded liner disposed within the overpack, the liner comprised of a polymer material, wherein the overpack and liner have a combined wall thickness of about 0.3 mm or less, and a base cup configured to at least partially surround an exterior of the overpack. In some embodiments, the liner has a volume of up to about 4.7 liters and an empty weight of between about 260-265 grams.
