Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
148 words
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.
Claim 2
Dependent Claim
148 words
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.
