ABSTRACT:
A liquid dispensing apparatus for dispensing heated liquid, such as hot melt adhesive, onto a substrate includes a dispenser body with a liquid dispensing nozzle portion which has a liquid discharge passage and outlet communicating with the dispenser body. An air cap is mounted to the dispenser body and has an opening to receive the liquid discharge outlet of the nozzle portion. The air cap has an air discharge passage for directing air onto the heated liquid as it exits the liquid discharge outlet. The air discharge passage is thermally isolated from the liquid discharge passage to allow the use of air which is substantially cooler than the heated liquid.
