Abstract
A push chain is used to drive a piston into a canister of extrudable material. The push chain is stored in an elongated chain magazine, withdrawn from the magazine and into the canister by actuation of a trigger connected to a sprocket for the chain. The push chain obviates the need for an elongated piston rod used in conventional extrudable material dispensers.
