ABSTRACT:
A protective dispensing assembly for ultrapure liquids which comprises an outer protective enclosure containing a flexible liquid container composed of fluorocarbon material which is inert and will not contaminate ultrapure liquid contained therein. The flexible dispensing container within the protective enclosure is formed by heat sealing a pair of fluorocarbon sheets so as to form an internal chamber for containing the liquid. The sheets form a bottom opening which receives a length of fluorocarbon tubing having its upper end in communication with the internal chamber. The sheets of the flexible container each form tab members located below the bottom opening of the container which are wrapped in overlapping manner about the fluorocarbon tubing and are heat sealed to form a tubing/container connection having efficient structural integrity. For further strength, a heat shrink sleeve is positioned about the wrapped tab members and is also heat sealed to the tab members and tubing. The protective enclosure, which is defined by two interfitting halves, provides protection for the flexible container such as during shipping and handling and also prevents light from degrading the material within the container. The protective enclosure also provides support for the container during use and exposes the outlet tubing of the container to thus permit dispensing of the liquid material while the protective enclosure remains closed.
