Abstract: A ram gun for dispensing viscous fluid products such as adhesive, caulking materials and the like is disclosed. The gun can be rechargeable or can be employed as a single charge, disposable device. In a particular embodiment, the gun is formed in two parts by molding from plastic material. One part comprises the ram. The other comprises a container section for the material to be dispensed and is provided with integrally formed nozzle, handle and trigger. The trigger has an integrally formed pawl. The trigger is attached to the handle by a thin plastic strip acting as a living hinge and biasing the trigger away from the handle. The ram is slidably mounted in the container section and is incrementally advanced therein by operation of the pawl and rack which is actuated by squeezing of the handle and trigger.
