摘要: A liquid dispensing apparatus for heated liquid, such as hot melt adhesive, onto a substrate includes dispenser body (12) with nozzle portion (16) which has discharge passage (30) and outlet (36) communicating the body. An air cap (18) is mounted to an opening receive of (16). The (44) directing it exits (36). thermally isolated from allow use substantially cooler than liquid.
