Abstract: A dispenser for viscous fluids includes a tubular cylindrical barrel member, a dispensing nozzle on one end of the barrel member and a piston element which is sealingly received in the barrel member and slidable therein in a direction toward the nozzle for dispensing a viscous fluid from the barrel member. The barrel member and the piston element are constructed so that the piston element is freely slidable in a reverse direction in the barrel member to relieve the pressure on the fluid in the barrel member after a dispensing operation has been completed and to thereby eliminate post extrusion from the dispenser. The dispenser is operative in combination with a dispenser gun which includes a drive plunger and an advancing mechanism which is operative for advancing the drive plunger in order to advance the piston element of the dispenser in the barrel member thereof.
