Abstract:
A method for folding a liner for packaging and/or insertion into an overpack. The method may include providing a liner comprising a substantially tubular body portion and a closed top and bottom, and a fitment formed in or affixed to the top of the liner, forming a gusset in the bottom panel of the liner, forming a gusset in the body portion of the liner, and fan-folding the liner. In some embodiments, the top of the liner may be a substantially circular top panel and the bottom of the liner may be a substantially circular bottom panel, with the top panel being attached to one end of the tubular body portion and the bottom panel being attached to an opposite end of the tubular body portion. In other embodiments, the liner may be a flexible, blow molded liner, thereby having no weld seams.
Abstract:
A fluid dispensing system for delivering a gas free chemical. The fluid dispensing system includes a gas separation device that separates a liquid from bubbles entrained in the liquid and accumulating the gas from the bubbles in a reservoir. A level sensor detects if the liquid in the reservoir drops too low, triggering the gas separation device to vent the gas from the reservoir. An empty detect apparatus that detects pressure droop of the liquid may also be implemented for taking appropriate action.
Abstract:
A shippable liquid storage and dispensing apparatus includes a collapsible liner arranged within a container, with a dispense head coupled to the container, suitable for handling oxygen- and moisture-sensitive materials. The dispense head includes a pressurization gas passage, a pressurization gas valve, a liquid passage, a liquid valve, a liner gas passage, and a liner gas valve, wherein each valve may have an associated quick connect fitting. The dispense head remains attached to the container during inert gas purging, liner filling, container shipment, and liquid dispensing. Pressurized inert gas may be maintained in the liner overlying liquid-containing material during shipment of the coupled dispense head and container. The container may have an extended chime to provide a protective zone that contains the entirety of the dispense head.
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 dip tube assembly having a tubular portion and a coupler portion, the coupler configured for removable coupling with the mouth of a container storing contents therein. The coupler portion comprises a first end for connection with a tubular portion; a second end for connection with a connector assembly, wherein the connector assembly provides a pressure to the container; an outer surface and an inner surface with a thickness therebetween, wherein the inner surface defines a lumen that allows the chemical fluid to be conveyed from the chamber through the tubular portion to the connector assembly; and at least one pressure relief feature on the outer surface.
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:
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.
