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 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:
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:
Improved fitment assemblies for headspace gas removal. In one configuration, a fitment assembly includes a fitment defining a fluid pathway between an interior and an exterior of a container, the fitment including a tubular body having an upper neck portion and a lower neck portion, the lower neck portion depending from the upper neck, the upper neck portion including a proximal end defining a proximal opening. The lower neck portion including a distal end defining a distal opening, the tubular body defining a central bore that passes therethrough, the central bore being concentric about a central axis and passing through the proximal opening and the distal opening a flange for coupling with a container, the flange extending radially outward at a junction with the upper neck portion and the lower neck portion, wherein the lower neck portion is configured to extend into the interior of the container.
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.
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:
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.
