  • Patent number: 4020975
    Abstract: A dispenser for semiliquid materials. The dispenser includes a cylindrical housing which is wall-mountable and which has an upper, closed end and a downwardly opening open end. The housing has a column coaxial within the housing attached to the closed end. The column serves as a fixed piston in cooperation with a cup which is threadedly engaged with the housing to telescopically sheath the piston. Rotation of the cup telescopically moves the cup over the piston thereby displacing the material in the cup through a spout in the base of the cup. The material may be either encapsulated and the capsule placed in the cup or the cup may serve as a container for a bulk quantity of material.
