  • Patent number: 4130149
    Abstract: A coffee dispenser includes a separate measuring cup member which may be inserted in a slide track positioned below a supply container. When inserted and moved in the slide track, the measuring cup member engages and actuates a spring-loaded slide closure. The slide closure is normally in a closed position but is moved to an open position by the measuring cup member to permit granular material from the supply container to pass through a dispensing opening and into the measuring cup member. Removal of the measuring cup member causes the spring-loaded slide closure again to close, and provides the user with a measuring cup full of granular material.
