Abstract
A canister lid (100) for a canister (500) includes an annular perimeter (101) surrounding an interior portion (102). Rather than completely surrounding the interior portion, the annular perimeter is instead interrupted by a suction conduit (103) defined by a suction duct (104) separating a first lobe (105) and a second lobe (106). The suction duct (104) intersects the annular perimeter such that the first lobe is disposed interior of the annular perimeter while the second lobe is disposed exterior to the annular perimeter. The canister lid can further include one or more ports (110,111) extending from the interior portion.
