Abstract
A battery-powered dispenser for hot melt adhesive includes an elongated housing supporting a battery power source therein. A heat exchanger is supported within the housing interior and includes an elongated heat exchanger and a resilient support guide sleeve for receiving a to-be-melted low temperature stick. The heat exchanger includes a discharge nozzle and a recess for receiving and supporting an escott heating element which is operatively coupled to the battery power source.
Claims11
For use in combination with a meltable material stick, a dispenser comprising:
- a housing defining an interior cavity and first and second apertures;
- a heat exchanger supported within said housing and defining a body, a nozzle end extending outwardly through said first aperture, a recess, a planar surface and a passage through said body;
- a disk-shaped heating element received at least partially within said recess having a first surface contacting said planar surface and an outer second surface;
- a connector supported in contact against said second surface,
- electrical power means within said housing including a battery power source and connection means for coupling said battery power source to said connector and said heat exchanger to energize said heating element;
- and
- a resilient guide sleeve having a guide passage therein coupled to said heat exchanger and extending outwardly from said interior cavity through said second aperture in said housing.
