  • Patent number: 8166580
    Abstract: A dispensing means (10) for delivering a dose of a first liquid into a second liquid is provided, the dispensing means comprising an enclosure (12) for the first liquid, and valve means (16), the dispensing means being operable such that raising a level (114) of a second liquid relative to the dispensing means so as to subject the dispensing means to hydrostatic pressure causes a dose of the first liquid to be displaced from the enclosure (12) to establish a column (118) of the first liquid that acts on the valve means, and subsequent lowering of the level (114) of the second liquid relative to the dispensing means so as to reduce the hydrostatic pressure acting on the valve means (16) causes the valve means to deliver the dose.

  • Patent number: 6748610
    Abstract: A toilet tank cleanser dispenser has a receiving holster suitable to receive an inverted container of cleaning composition and suitable to dose liquid from the container. The adapter has an internal dosing shuttle for metering an aliquot of cleanser through an opening at the bottom of the adapter defining a valve seat. A float can move up and down with respect to the liquid level in the tank to drive an outlet valve against an outlet of the adapter. The valve head can have a balloon-like structure driven by the float. For example, a low density thin wall polyethylene valve head can be supported by a trapped air pocket to reduce leakage, permit some flexibility, and avoid permanent deformation.
