A container for distributing doses of a treatment fluid to a mass of water in a toilet tank which has a level which falls and rises upon slushing of the toilet tank comprises a fluid chamber at the top, a neck at the bottom, and a dosing device mounted in the neck. The fluid chamber contains the treatment fluid and a first mass of air above the treatment fluid, and has a single opening therein. The neck points downwardly into the toilet tank for alternate immersion and removal from the mass of water as the level of the mass of water rises and falls, is in fluid communication with the fluid chamber through the single opening in the chamber, and has a free edge. The dosing device has a first stage of operation when the level of the mass of water in the tank is rising and a second stage of operation when the level of the mass of water in the tank is falling, and comprises a transverse wall at a distance from the free edge of the neck means defining an air chamber and having an aperture therethrough, the aperture defining an evacuation hole means in the air chamber, a passage having an upper end which opens into the evacuation hole and a lower end having an opening defining a discharge hole, and gravity-operated, movable, mechanical regulating device positioned in the passage for regulating the doses distributed as the fluid chamber is emptied, the regulating device supporting a column of the treatment fluid.

A toilet lid solution apparatus which replaces a toilet reservoir lid. The apparatus stores a chosen disinfectant solution and meters the dispensing thereof with each flush. The apparatus' installation requires no special tools, knowledge or changes to the toilet or reservoir for installation.
A dispenser for use in a toilet tank is disclosed. There is a replaceable bottle There is also an upwardly open holster for receiving the bottle in inverted fashion. A valve is associated with the holster that controls the dispensing of cleaner from the container, and/or a mounting hook is provided on the holster that can pivot between a storage position in a bottle recess and a mounting position snap locked on the holster (or is integrally linked to the holster).
A dispenser is provided for dispensing cleaning chemicals such as toilet bowl cleaners. It has a dosing chamber containing therein a floating shuttle that seals a lower opening in the dosing chamber and floats up there from as an aliquot of chemical is prepared for release during the next cycle. There is also a float controlled external valve head at a lower end of the dispenser for alternately opening and closing a lower opening in the dosing chamber. The level of water in the toilet tank controls the movement of the valve head, and dispensing of the cleaner chemical controls movement of the floating shuttle. A grommet provides a valve seat for both the floating shuttle and valve head.
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.
