Abstract:
The present disclosure relates to novel and advantageous connector assemblies for use with a liner-based assembly. In one embodiment, a connector assembly for use with a liner-based assembly can include a pressure port, a dispense port, a headspace removal port, and a locking mechanism. The pressure port can be adapted for connection to a pressure source. The dispense port can be adapted for fluid communication with a source of material to be dispensed from the liner-based assembly. The headspace removal port may be configured for removing a gas from the liner-based assembly. The locking mechanism may be used for locking the connector to the liner-based assembly when contents therein are under pressure. In some embodiments, the dispense port and headspace removal port may be operably coupled providing a flow path for recirculation of the contents within a liner of the liner-based assembly.
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.
Abstract:
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.
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:
Systems are described for delivery of a wide variety of materials in which liquid and gas or vapor states are concurrently present, from a package preferably including a fluid-containing collapsible liner. Headspace gas is removed from a pressure dispensing package prior to liquid dispensation therefrom, and ingress gas is removed thereafter during dispensation operation. At least one sensor senses presence of gas or a gas-liquid interface in a reservoir or gas-liquid separation region. A gas removal system including an integral reservoir, at least one sensor, and at least one flow control elements may be included within a connector adapted to mate with a pressure dispensing package, for highly efficient removal of gas from the liquid being dispensed from the container.
Abstract:
A liner-based pressure dispensing container includes a connector-mounted probe arranged to seat a dip tube against an inner surface of a liner fitment for sealing utility. A dip tube and probe may include increased and/or matched flow area. A reverse flow prevention element can be arranged proximate to a liquid extraction opening to inhibit reverse flow of liquid from a dip tube into a container. A liner-less container may include a reduce diameter lower portion arranged to receive a dip tube, with at least one associated sensor to sense a condition indicative of depletion of liquid from the lower portion. A shipping cap can be included for removing headspace gas from the liner. In one embodiment, the shipping cap is suitable for direct connection to a dispensing process.
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:
A dispensing assembly for a pressure dispense package includes a connector having separate and distinct liquid and extraction conduits, and having a pressurization gas conduit. A liner fitment adapter may include a longitudinal bore to receive a probe portion of a connector defining a liquid extraction conduit, and may include a lateral bore to enable removal of gas. Insertion of a connector into a dispensing assembly simultaneously makes fluidic connections between (a) a gas extraction conduit and a dispensing volume; (b) a liquid extraction conduit and the dispensing volume, and (c) a pressurization gas conduit and a space to be pressurized within a pressure dispense vessel. Presence of fluid or change in phase of flowing fluid within a fluid circuit may be sensed by comparing outputs of first and second temperature sensing elements, with one sensing element including a heater to increase temperature of the sensing element in exposure to gas but not in exposure to liquid. A system and method for fluid dispensing includes a first pressure dispense apparatus and a sensing element arranged to sense a condition correlative of approach to gas saturation of dispensed fluid, and in response to such sensed condition initiates dispensation by a second pressure dispense apparatus for combining pressure dispensed fluid flows supplied to a point of use.
