Abstract
Abstract A pneumatic spray gun container assembly having a suction tube through which a substance to be sprayed, such as paint, feeds from the container proper of the assembly to the spray gun. A stirrer, such as a flexible paddle, is fixed to the suction tube within the container, and the container is rotatable relative to the tube and stirrer to effect stirring of the container contents periodically during spraying operation without opening the container. A finger operated latch is provided for releasably securing the suction tube and container in a fixed relative angular position between stirrings.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
85 words
A container assembly for a spray gun or the like comprising: a closed container for the substance to be sprayed, a suction tube extending rotatably through one wall of said container having an outer end outside the container, a stirrer secured to said tube within said container, and exposed means secured to the outer end of said tube whereby said latter means and container may be grasped to effect relative rotation of said container and tube and thereby relative rotation of said stirrer and container.
Claim 2
Dependent Claim
85 words
A container assembly for a spray gun or the like comprising: a closed container for the substance to be sprayed, a suction tube extending rotatably through one wall of said container having an outer end outside the container, a stirrer secured to said tube within said container, and exposed means secured to the outer end of said tube whereby said latter means and container may be grasped to effect relative rotation of said container and tube and thereby relative rotation of said stirrer and container.
