Abstract:
A paste dispenser for dispensing paste from a paste container, said paste dispenser comprising:a walled housing having a paste ingress opening and a paste egress opening; a first vane connected to and angularly spaced from a second vane, said vanes rotatably connected about an axis, said axis connected to said housing near said paste egress opening, each said vane having a perimeter; a contoured surface disposed within said housing, said surface shaped so that as said vanes are rotated about said axis, said surface remains in proximate relationship with said perimeter of at least one said vane; biasing means for urging said first vane toward said housing wall; said surface, said first vane, and said second vane defining boundaries of a paste-receiving chamber having a gap disposed toward said paste ingress opening; and, so that pressurized paste from the paste container may flow into said paste ingress opening, pass through said gap, fill said paste-receiving chamber, thereby exerting pressure upon said second vane, thereby causing said vanes to rotate about said axis until said first vane blocks said gap and said flow then exerts pressure upon said first vane thereby continuing said rotation, finally causing the paste from said paste-receiving chamber to be deposited at said paste egress opening.
