ABSTRACT:
A passive dosing dispenser for issuing, for example, a predetermined volume of a toilet tank additive solution into a toilet tank as the water is draining therefrom while the toilet is flushing. A preferred dispenser comprises a reservoir for containing a quantity of a toilet tank additive type product and in which reservoir a solid type product can be dissolved to form a product solution. In operation, while the water in the toilet tank is receding from about the dispenser, a predetermined dose-volume of toilet tank water is vacuum-transferred into the reservoir through an inlet conduit, and a substantially equal dose-volume of the product solution is dispensed through a discharge standpipe. The dispenser may further comprise an internal baffle to precipitate mixing and agitation inside the dispenser which promote dissolution. The dispenser also provides an air-lock when immersed in a full toilet tank which air-lock isolates the product and product solution from toilet tank water which surrounds the dispenser during quiescent periods. In a particularly preferred embodiment, a dispenser which further isolates the solid type product from the product solution during quiescent periods is provided. Plural product co-dispensers which embody the present invention are also disclosed.
