Abstract: A dust control device for withdrawing airborne particles from a container includes a body defined by a cylindrical wall and having a hollow interior extending between first and second open ends. The cylindrical wall has a continuous circumferential surface extending from the first open end to the second open end, a funnel-shaped inlet portion extending from the first open end, a base located at the second open end that is engageable with a container and that extends around at least a portion of the circumferential surface of the cylindrical wall, an outlet port located between the first and second open ends of the body, and a channel extending around the circumferential surface of the cylindrical wall that is in fluid communication with the outlet port. The channel has a bottom opening extending around the circumferential surface of the cylindrical wall and wherein the base surrounds the channel.

Abstract: This invention (FIG. 1) was conceived out of necessity to control hazardous conditions created while mixing materials like concrete or mortar in containers (1) such as a three gallon or five gallon bucket. The invention (2) is a vacuum attachment which produces a low pressure zone within the bucket when a vacuum is applied to the outlet port (3) of the invention that will keep dust and other airborne material from leaving the interior of the invention through the top of the opening (4). It consists of a funnel shaped opening (4) on the top and a channel around the underside of the funnel leading to the vacuum attachment opening (3), which creates high and low pressure zones, which controls the release of particulate into the atmosphere.
