20120267388 | Substantially Rigid Collapsible Liner and Flexible Gusseted or Non-Gusseted Liners and Methods of Manufacturing the Same and Methods for Limiting Choke-Off in Liners - 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. | 10-25-2012 |
20130193164 | SUBSTANTIALLY RIGID COLLAPSIBLE LINER, CONTAINER AND/OR LINER FOR REPLACING GLASS BOTTLES, AND ENHANCED FLEXIBLE LINERS - 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. | 08-01-2013 |
20130213824 | LINER-BASED ASSEMBLY FOR REMOVING IMPURITIES - The present disclosure relates to a liner for storing a material, the liner including at least two layers, wherein a layer that is in contact with the material is an active layer. The active layer may be made active by incorporating a scavenger into the layer. At least one layer of the liner may comprise a polymer or a fluoropolymer. In some embodiments, the active layer may be configured for removing microbridging components in photoresists. In some embodiments, the active layer may be made active by coating the interior of the layer with an inert material, such as glass. In further embodiments, the liner may be positioned within a stainless steel canister. The present disclosure also relates to a liner-based assembly including a liner for storing a material, an overpack within which the liner is positioned, and a purifying packet positioned between the liner and the overpack. | 08-22-2013 |
20140034671 | GENERALLY CYLINDRICALLY-SHAPED LINER FOR USE IN PRESSURE DISPENSE SYSTEMS AND METHODS OF MANUFACTURING THE SAME - 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. | 02-06-2014 |
20140117043 | LINER-BASED DISPENSING SYSTEMS - The present disclosure relates to novel and advantageous disposable dispensers. The dispenser may include a dispense assembly comprising an outlet channel in fluid communication with a terminal apparatus, and a pressure source providing a limited supply of fluid or gas, and also includes a collapsible liner that contains a material to be dispensed, the liner detachably secured to the dispense assembly with the outlet channel in fluid communication with an interior of the liner, wherein the material in the liner is dispensed out the liner and through the outlet channel to the terminal apparatus. | 05-01-2014 |
20140202975 | NESTED BLOW MOLDED LINER AND OVERPACK AND METHODS OF MAKING SAME - 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. | 07-24-2014 |
20140209627 | SUBSTANTIALLY RIGID COLLAPSIBLE CONTAINER WITH FOLD PATTERN - The present disclosure relates to a blow-molded, rigid collapsible container that can be suitable for storage and dispensing systems of practically any size. The rigid collapsible container may be a stand-alone container. The container may be blow-molded as a unitary piece that may include folds or pre-folds that allows the container to collapse into a relatively flat position. In an expanded state, the container may have a generally trapezoidal prism shape. | 07-31-2014 |
20140374416 | LINER-BASED SHIPPING AND DISPENSING SYSTEMS - 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. | 12-25-2014 |
