.~ Including means to flex diaphragm within rigid reservoir
DEFINITION
Classification: 401/145
(under subclass 143) Implement wherein the reservoir is essentially of inflexible wall structure but further includes a pliant or resilient membrane positioned at all times entirely within the confines of the wall structure, and means for deforming the membrane within the reservoir so as to increase or decrease the available material holding space in the reservoir and thereby produce the material-moving force.
