Zusammenfassung:	The mechanically operated dispenser has a rotatable actuator connected with at least one expansible chamber to effect operation of the latter to draw material to be dispensed from a container into the expansible chamber to then pressurise the material. An expansible bulb is connected with the chamber and with a dispensing nozzle, and has a volumetric capacity several times as great as the expansible chamber. Valves are associated with the bulb to control flow into and out of the bulb, whereby the rotatable actuator and expansible chamber are operative to repeatedly draw material from the container, pressurise it and transfer it under pressure into the bulb. The bulb expands as material is added to it, and the elasticity of the bulb acts to exert a substantial pressure on the material in the bulb. Subsequent operation of the dispensing nozzle releases the material from the expanded bulb, and the bulb returns to its normal, at-rest condition.
