ABSTRACT:
A manually actuated dispensing device for use with double dispensing cartridges for delivering two-component compositions comprises a double thrust ram for each cartridge and a drive member jointly acting on the thrust ram and being actuated by a trigger lever, the drive member comprising a thrust member which acts upon a toothing on the thrust ram. The thrust member comprises a driving dog provided with several teeth and being under the action of a spring, the driving dog acting substantially perpendicularly on the toothing of the thrust ram, and the thrust member acting essentially in the direction of the thrust ram or, respectively, the dispensing direction only. Such a dispensing device can be manufactured from a small number of low-priced parts of synthetic material and allows by the use of several teeth a substantial lowering of the contact-pressure, and a fast re-gripping of the trigger lever having a very small backlash.
