APPARATUS AND METHOD FOR PRESSURE DISPENSING OF HIGH VISCOSITY LIQUID-CONTAINING MATERIALS

摘要

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.

主权项

1. A pressure dispensing apparatus comprising:
a rigid container comprising a neck defining a container opening; a collapsible liner arranged within the container, the collapsible liner comprising an aperture-defining liner fitment arranged in or along the neck of the rigid container; a downwardly-extending dip tube arranged within the liner; a connector engaged to the neck of the rigid container and including a probe defining a fluid flow passage therethrough, wherein an upper portion of the dip tube is arranged to receive a lower portion of the probe, and wherein the lower portion of the probe is arranged to seat an upper portion of the dip tube against an inner surface of the fitment, the dip tube being in direct contact with the lower portion of the probe and in direct contact with the fitment to sealingly engage the dip tube between the probe and the fitment; and a stress concentrator that provides sealing engagement between the dip tube and at least one of the probe and the fitment.
