Abstract: An additive product dispensing apparatus for a toilet tank which prevents waste of excessive chemicals within the toilet tank and causes the treatment solution to remain in the toilet bowl water after the flushing cycle. The dispensing apparatus includes a product chamber for receiving the additive product. The product chamber communicates with an overflow pipe of the toilet tank by way of a conduit assembly having three ball check valves associated therewith. The check valves allow dispensing of a specific dosage of the product and are responsive to the rise and fall of water in the tank.
Abstract: A container for an air freshening liquid including a bottom portion having a bottom wall and at least one lateral wall. The container has a liquid-permeable upper wall. The lateral wall includes at least one open groove extending to the upper wall whereby liquid in the container rises by capillary action to the upper wall which absorbs the liquid for evaporation.
Abstract: An air-freshening device including an air-freshening fluid container having a removable cap with a wick support. A fluid-absorbent medium has an exposed surface on the cap and a wick extends through the cap to the fluid-absorbent medium. An outer closure support for the container has a pair of adjustable closure half-shells. Each half-shell has an internal locking arm for engaging the flange of the cap for controlling the air freshener flow out of the device.
