ABSTRACT MELT DISPENSERS A device for use in a hand held hot melt gun to prevent drool of melted composition from the outlet thereof when the gun is not in use is described and claimed. In one embodiment of the invention the device comprises a melt body 10 having a melt chamber 12, resilient means provided by a coil spring 26 and means 36 for heating the melt body. When in use a rod of composition urged by a feeding force in a direction towards the melt body 10 is melted in the melt chamber 12 and is dispensed in molten condition from the outlet 20. When the feeding force is released after use the spring exerts sufficient force in a reverse direction to the direction of the feeding force to move the rod outwardly of the melt body, which relieves the pressure within the melt body and thereby substantially prevents further composition from drooling from the outlet.
