Abstract

A canister lid (100) for a canister (600) 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.

First claim

What is claimed is:

1. A canister lid, comprising:
an annular perimeter surrounding an interior portion, the annular perimeter interrupted by a suction conduit defined by a suction duct separating a first lobe and a second lobe, the first lobe disposed interior of the annular perimeter, the second lobe disposed exterior to the annular perimeter, and the suction duct traversing the annular perimeter, the suction conduit comprising a first lobe annular wall, a second lobe annular wall, and one or more suction duct sidewalls;
a suction conduit cap coupled to each of the first lobe annular wall, the second lobe annular wall, and the one or more suction duct sidewalls; and
one or more ports extending from the interior portion.

2. The canister lid of claim 1 , the one or more ports comprising two ports.

3. The canister lid of claim 2 , one port of the two ports comprising a pour spout.

4. The canister lid of claim 3 , another port of the two ports comprising a suction port.

5. The canister lid of claim 4 , the suction port extending distally away from the interior portion farther than the pour spout.

6. The canister lid of claim 4 , further comprising one or more caps to cover the one or more ports on a one-to-one basis, each of the one or more caps coupled to the annular perimeter by a corresponding tab extending from the annular perimeter.

7. The canister lid of claim 4 , the first lobe, the pour spout, and the suction port radially separated by about 120 degrees along the interior portion.

8. The canister lid of claim 1 , the canister lid comprising a canister engaging side, the interior portion defining a convex surface toward the canister engaging side and spanning an interior of the annular perimeter.

9. The canister lid of claim 1 , the annular perimeter defining a canister lip edge receiving recess.

10. The canister lid of claim 9 , the canister lip edge receiving recess comprising:
a first annular wall;
a second annular wall; and
a bridge spanning the first annular wall and the second annular wall.

11. The canister lid of claim 10 , the canister lid comprising a canister engaging side, further comprising a barrier wall extending from the interior portion distally toward the canister engaging side.

12. The canister lid of claim 11 , a major axis of the one or more ports oriented substantially parallel with the barrier wall.

13. The canister lid of claim 1 , further comprising a disposable liner attached to the canister lid.

14. The canister lid of claim 1 , the first lobe annular wall and the second lobe annular wall having one of a rectangular, triangular, free form, ovular, pentagonal, or hexagonal cross sectional shape.

15. The canister lid of claim 1 , the first lobe annular wall and the second lobe annular wall each substantially circular in cross section.

16. The canister lid of claim 13 , the first lobe annular wall greater in circumference than the second lobe annular wall.

17. The canister lid of claim 1 , further comprising a canister.

18. The canister lid of claim 17 , the canister comprising a lip, a sidewall, and a suction port extending distally from the sidewall, the second lobe to engage the suction port when the annular perimeter engages the lip.
