ABSTRACT MELT DISPENSERS A melt body (16) for a melt dispenser is disclosed which is particularly suitable for use in a hand held hot melt glue gun for use with rods of hot melt glue. The melt body including a melt chamber (17) provided with a series of fin elements (23) which define passageways terminating at an outlet (21). The fin elements increase in size progressively from an inlet (19) of the melt chamber to the outlet and ensure good transfer of heat to material to be melted. Edge surfaces of the fin elements provide surface portions of an opening adapted to receive the central portion of a rod as the rod is fed into the melt chamber. The shaping of the fin elements is such as to permit convenient manufacture by a die casting process. The spacing of the fin elements is selected so that melted material flows from the outlet when its viscosity has been reduced to an appropriate value to ensure good adhesive bonding. The arrangement permits improved consistency of heating the material and thus improved control of temperature of dispensed material. Also described is an improved hand held hot melt glue gun incorporation such a melt chamber, and incorporating a trigger operated feeding means (14).
