A liquid dispenser (10) for dispensing a liquid (16) from a reservoir (15) to a dispensing location is disclosed. The dispenser (10) includes a dispenser head member (11) adapted for engaging the reservoir (15). The head member (11) has a bore (18) having a first opening (18a) and second opening (18b). The first opening (18a) is proximate the reservoir (15) and the second opening (18b) is proximate the dispensing location. A stem member (19) is slideably mounted in the bore (20). The stem member (19) has a measuring cavity (21). The measuring cavity (21) is in fluid communication (15) when in a filling position wherein the liquid enters the measuring cavity and the measuring cavity (21) dispenses a given volume of product (16) from the measuring cavity (21) when in the dispensing position and when in a position intermediate the dispensing and filling positions the measuring cavity (21) is enclosed by the head member (11). A return spring (28) cooperatively connected to the first end of the stem member (19) and a cup (39) is cooperatively connected to the bottom of the stem member (19). The return spring (28) and cup (39) provide for moving the stem member (19) between a filling position and dispensing position based on the rise and fall of water caused by the spray action of a dishwasher.

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.

In-tank toilet bowl cleaner dispenser

Fabrics are treated in machine drying apparatus to reduce static electricity carried by the fabrics, soften the fabrics and improve other fabric properties. A sponge impregnated with a heat softenable solid or semi-solid fabric-conditioning agent is placed within the dryer drum and the fabrics are tumbled in the dryer thereby causing some of the fabric-conditioning agent to be transferred to the fabric. When the dryer is heated, the heat of the dryer helps the fabric-conditioning agent to soften and assists in its distribution over the surface of fabric with which the impregnated sponge is brought into tumbling contact.

Treatment of fabrics in machine dryers

Fabrics are treated in machine drying apparatus to reduce static electricity carried by the fabrics, soften the fabrics and improve other fabric properties. A reusable dispenser of solid or semi-solid fabric-conditioning agent is placed in the dryer drum and tumbled with the fabrics in the dryer thereby causing some of the fabric-conditioning agent to be transferred to the fabric. When the dryer is heated, the heat of the dryer helps cause the fabric-conditioning agent to soften and assist in its distribution over the surface of fabric with which it is brought into tumbling contact.
