Abstract
A dispense head assembly includes a bung adapter, a body receiver, and a dispensing body. The bung adapter inserts into a drum. The body receiver selectively inserts into the bung adapter, and the dispensing body selectively inserts into the body receiver. A single, unobstructed, uniform-diameter flowpath routes fluid from the drum into a chamber within the body receiver. A movable piston within the chamber selectively blocks fluid flow between the fluid flowpath and a dispense opening on the dispensing body. The body receiver and the dispensing body are key matched, for safe and rapid coupling and decoupling.
