ABSTRACT:
An apparatus and a method for dispensing hot melt adhesive or other materials. The apparatus includes a container and an outlet. The container has a first material (the material to be dispensed) disposed therein, which changes from a solid state or a state of high viscosity to a state of low viscosity when heated above a predetermined temperature. The container also has a second material disposed therein, which is adapted to be heated above a predetermined temperature when subjected to microwaves for at least a predetermined period of time. The second material is in a heat transfer relationship with the first material. While the dispenser is being subjected to microwaves, the second material converts the microwave energy into heat and transfers the heat to the first material. The first material then changes to a state of low viscosity and can be dispensed from the container through the outlet.
