Abstract

A dispenser (10) for use in a flush tank of a toilet is disclosed. The flush tank has a first water level (17) during quiescent periods and a second water level (18) when the toilet is flushed. The dispenser (10) includes a housing (11) having a top (11a) and bottom (11b). The housing (11) defines a reservoir (12) having an inlet (13) proximate the top (11a) and an outlet (14) positioned lower than the inlet (13). The reservoir (12) holds the product to be dispensed, the product dissolving in water and forms a solution. A first valve means (16) for regulating flow of water from the flush tank into the reservoir (12) through the inlet (13) is provided. The first valve means (16) is responsive to changes from the first water level (17) to the second water level (18). The second valve means (24) regulates flow of solution out of the reservoir (12 ) through the outlet (14). The second valve means (24) is also responsive to changes from the first water level (17) to the second water level (18), whereby when the water rises to its first water level (17), the second valve means (24) is closed. Water enters the reservoir (12) through the inlet (13) until the reservoir (12) is filled causing the first valve means (16) to close. The first valve means (16) and second valve means (24) minimize migration of the solution out of the reservoir (12) during quiescent periods. When the water is at the second water level (18), the second valve means (24) opens and allows the solution to flow out of the outlet 14.
