60557-4130 ABSTRACT A spray dispensing assembly for liquid materials comprises a container having a hole, a cover for initially closing said hole, and means for selectively opening said hole. A spray head inlet has a connection for detachable joining with a source of pressurized air, and an outlet for discharging a spray of liquid materials. A non-releasable coupling selectively secures the spray head to the container and over the hole in captive fashion after the hole is opened, thereby substantially hindering refilling of the container. The coupling includes a leg for extension into the hole, the leg including a groove for snap fit reception of the container adjacent said hole.
