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.

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 semicircular lobe and a second semicircular lobe, the first semicircular lobe disposed interior of the annular perimeter, the second semicircular lobe disposed exterior to the annular perimeter, and the suction duct traversing the annular perimeter;
one or more arcuate handles coupled between the annular perimeter and the second semicircular lobe; 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, another port of the two ports comprising a suction port, the suction port extending distally away from the interior portion farther than the pour spout.

4. The canister lid of claim 3 , the one or more arcuate handles comprising at least two arcuate handles, with each arcuate handle being separated from the annular perimeter except at a first end and a second end, and wrapping radially about a common center with an exterior wall of the annular perimeter.

5. The canister lid of claim 4 , the one or more arcuate handles comprising three arcuate handles, with a first arcuate handle coupled to the annular perimeter at two ends, and each of a second arcuate handle and a third acruate handle being coupled between the annular perimeter and the second semicircular lobe.

6. The canister lid of claim 5 , 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 arcuate tab extending from the annular perimeter.

7. The canister lid of claim 5 , the first semicircular 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 , the suction conduit defining a tapered stadium perimeter in plan view.

14. The canister lid of claim 13 , the suction conduit comprising frustoconical suction duct sidewalls coupling the first semicircular lobe and the second semicircular lobe.

15. The canister lid of claim 14 , the second semicircular lobe having a radius less than the first semicircular lobe.

16. The canister lid of claim 15 , further comprising a disposable liner coupled to the canister lid.

17. The canister lid of claim 16 , 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 semicircular lobe to engage the suction port when the annular perimeter engages the lip.

19. A canister lid, comprising:
an annular perimeter surrounding an interior portion;
a frustoconical central duct separating a first semicircular lobe and a second semicircular lobe;
an arcuate handle having a first end coupled to the annular perimeter and a second end coupled to the second semicircular lobe;
the frustoconical central duct intersecting the annular perimeter such that the first semicircular lobe is disposed interior to the annular perimeter and the second semicircular lobe is disposed exterior to the annular perimeter.

20. The canister lid of claim 19 , the canister lid comprising a canister engaging side and a top side opposite the canister engaging side, the annular perimeter defining a canister lip edge receiving recess open to the canister engaging side, the canister lid further comprising one or more ports extending distally from the interior portion from the top side.
