Benefits of technology

This solution ensures a consistent and limited release of liquid per flush, independent of refill time, preventing excessive loss and ensuring the liquid is not wasted if the tank remains empty for an extended period.

Problems solved by technology

A float valve inside the neck of the bottle is held in a closed position by the water, until the toilet is flushed, causing the water level to drop, and thereby causing the valve to open.
But a single malfunction of the flush mechanism may cause the tank to remain empty long enough for all the liquid to escape from the bottle, before the problem is discovered.

Embodiment Construction

[0011] In FIG. 1a middle section 11 is seen to include a tubular member 14 adapted to fit into the neck of a bottle or other container from which a liquid is to be dispensed. Beveled surface 15 supports a shoulder area 16 which is connected to a tubular extension 17. A lip 18 acts to prevent the assembly from slipping too far into the bottle.

[0012] In FIG. 1b lower section 12 is seen to include a tubular float member 20 which is lifted by the water level in the tank, so that the float valve closes when rim 21 is pushed into sealing contact with the under side of shoulder 16. In an alternate embodiment, float valve closure is provided by contact of the lower end of wall 19 on a beveled wall inside the lower section. If desired, both float valve closure seats can be provided in the same embodiment. At the same time, push rod 22 moves rod 25 and thereby lifts section 13, to open the second valve.

[0013] In FIG. 1c the upper section is seen to include a tubular member 24 having a close...

Abstract

A two-way flow control valve for repeatedly dispensing a limited amount of liquid. A float valve is linked to a second valve and storage chamber such that one valve is closed when the other is opened, and vice versa. The chamber fills when the float valve is closed, and empties when the float valve is opened. The assembly is useful for dispensing a liquid cleaner into a toilet tank.

Description

FIELD OF THE INVENTION [0001] This invention relates to flow control apparatus including a valve assembly for dispensing a liquid; and more particularly to a valve for the intermittent release of a controlled amount of liquid from an inverted container, to be used for example in a toilet tank. BACKGROUND OF THE INVENTION [0002] Many products have been developed and marketed for the intermittent release of a cleaning agent, disinfectant, or deodorant into a flush-type toilet tank. Typically, an inverted bottle of liquid is suspended inside the tank, so that the neck of the bottle is immersed in water. A float valve inside the neck of the bottle is held in a closed position by the water, until the toilet is flushed, causing the water level to drop, and thereby causing the valve to open. The liquid then flows from the bottle, until the tank is again full of water. The amount of liquid released from the bottle after each flush depends of course upon the time required for the tank to re-...
