  • Patent number: 5546774
    Abstract: A dispenser device for use with an automatic washing machine and a wash tub having a drain. The device has an elongated housing having a drain passage disposed therethrough. The housing has a first end provided with a first opening and a second end provided with a second opening, with both openings being connected to the drain passage. A sealing gasket is provided at the second end of the housing around the second opening. A means for mounting the device within the wash tub and means for selectably placing the device into a sealed and an unsealed position are also provided. When the device is in the sealed position, the gasket makes sealing contact with the wash tub around the wash tub drain. Thus, when sealed, fluid that enters the first opening travels through the drain passage and down the wash tub drain, while fluid that enters the wash tub is stored in the wash tub and is prevented from travelling down the wash tub drain.
