Several embodiments of small volume containers for use to feed liquid to a gravity feed liquid spraying device. Each container comprises a body portion having axially spaced first and second ends, means for closing the second end of the body portion, and a first adapter attached to the first end of the body portion. The body portion, means for closing, and first adapter have inner surfaces defining a cavity in the container having a small volume. The adapter comprises an engagement portion having a through opening communicating with the cavity in the body portion, which engagement portion is adapted for liquid and air tight engagement an inlet port of the spraying device. The container includes vacuum restricting means for restricting vacuum within its cavity as liquid moves out of its cavity into a spraying device through the opening in the first adapter with the second end of the container uppermost.
A spray gun 101 has a spray head 150 connected to a body 102 of the spray gun 101 and a reservoir 156 connected to the spray head 150 for supplying liquid to a spray nozzle 153 of the spray head 150. The spray head 150 is arranged so that liquid from the reservoir 156 is delivered to the spray nozzle 153 without passing through the spray gun body 102 in response to actuation of the spray gun 101 via a trigger 105. The spray head 150 is releasably secured and can be detached from the spray gun body 102 and thrown away after use. The reservoir 156 is mounted on the spray head 150 and can be removed and thrown away with the spray head 150 after use.
