  • Patent number: 4946456
    Abstract: An agent dispenser of the fluid imbibing type having a flexible bag within a membrane and in which a wicking or wetting device is in contact with the outer surface of the membrane to keep such outer surface wet at all times for all attitudes of a containment vessel housing the bag and the membrane. The wicking device is in the form of a fabric tube, such as a stretch knit fabric, or a preformed hydrophilic polymeric sleeve, which can be mounted on the outer surface of the membrane and remain in contact with it so long as there is any liquid in the containment vessel. Since the amount of water drawn by the wicking device is controlled by the membrane porosity and the amount of a solute composition in an intermediate layer between the bag and the membrane, the wicking device provides for a continuous controlled delivery of agent from the inner bag of the dispenser.
