Abstract

A liquid container includes a cup having a brim forming an opening into an interior region of the cup. The container also includes a lid configured to mount on the brim of the cup to close the opening.

First claim

1 . (canceled)

2 . A drink cup lid comprising
a central closure and a brim mount coupled to the central closure, wherein the brim mount is adapted to be mounted on a brim of a cup to retain the central closure on the cup to close a mouth opening into the cup, the brim mount including a first seal ring with a first sloped inner surface which is adapted to engage the cup to establish a first annular liquid flow barrier between the lid and the cup, a second seal ring with a second sloped inner surface which is adapted to engage the cup to establish a second annular liquid flow barrier between the lid and the cup, a third seal ring with a third sloped inner surface which is adapted to engage the cup to establish a third annular liquid flow barrier between the lid and the cup, and a fourth seal ring with a fourth sloped inner surface which is adapted to engage the cup to establish a fourth annular liquid flow barrier between the lid and the cup, wherein each of the first, second, third, and fourth sloped inner surfaces are defined relative to a horizontal axis, wherein the first sloped inner surface has a greater slope than the second sloped inner surface, and wherein the second sloped inner surface has a greater slope than the fourth sloped inner surface.

3 . The drink cup lid of claim 2 , wherein each of the first, second, and third seal rings has a frustoconical shape and the fourth seal ring has a curved shape.

4 . The drink cup lid of claim 2 , wherein the brim mount includes a portion between the second seal ring and the third seal ring that is configured to be spaced apart from the brim when the second annular liquid flow barrier and the third annular liquid flow barriers are established.

5 . The drink cup lid of claim 4 , wherein the portion between the second seal ring and the third seal ring that is configured to be spaced apart from the brim when the second annular liquid flow barrier and the third annular liquid flow barriers are established is substantially continuously spaced apart from the brim along the length of the portion of the brim mount.

6 . The drink cup lid of claim 4 , wherein the portion between the second seal ring and the third seal ring is substantially planar and is attached to the third seal ring.

7 . A drink cup lid comprising
a central closure and a brim mount coupled to the central closure, the brim mount sized and shaped to attach to a brim of a cup, the brim mount forming a perimeter surrounding the central closure, and the brim mount including a first seal ring with a first sloped inner surface which is sized and shaped to establish a first annular liquid flow barrier between the lid and the cup, a third seal ring with a third sloped inner surface which is sized and shaped to establish a third annular liquid flow barrier between the lid and the brim of the cup, and a fourth seal ring with a fourth sloped inner surface which is sized and shaped to establish a fourth annular liquid flow barrier between the lid and the brim of the cup, wherein each of the first, third, and fourth sloped inner surfaces are defined relative to a horizontal axis, wherein the first sloped inner surface of the brim mount has a greater slope than the fourth sloped inner surface of the brim mount, wherein the brim mount includes a portion between the first seal ring and the third seal ring that is spaced apart from the brim when the first annular liquid flow barrier and the third annular liquid flow barrier are established, and wherein the portion between the first seal ring and the third seal ring that is spaced apart from the brim when the first annular liquid flow barrier and the third annular liquid flow barrier are established is substantially continuously spaced apart from the brim along the length of the portion of the brim mount.

8 . The drink cup lid of claim 7 , wherein each of the first and third seal rings has a frustoconical shape and the fourth seal ring has a curved shape.

9 . The drink cup lid of claim 8 , wherein the portion between the first seal ring and the third seal ring that is spaced apart from the brim when the first annular liquid flow barrier and the third annular liquid flow barrier are established is substantially planar and is attached to the third seal ring.

10 . The drink cup lid of claim 9 , wherein the portion between the first seal ring and the third seal ring that is spaced apart from the brim when the first annular liquid flow barrier and the third annular liquid flow barrier are established is coupled to the first seal ring.

11 . The drink cup lid of claim 10 further comprising an annular connection portion interposed between and coupling the first seal ring and the third seal ring, and the annular connection portion is angled relative to the horizontal axis.

12 . A drink cup lid comprising
a central closure and a brim mount coupled to the central closure, the brim mount sized and shaped to attach to a brim of a cup and form a plurality of annular liquid flow barriers including a first annular liquid flow barrier, a third annular liquid flow barrier, and a fourth annular liquid flow barrier, wherein the brim mount forms a perimeter surrounding the central closure, the brim mount having an annular inner portion adjacent the central closure and an oppositely disposed annular outer portion, a brim mount top interposed between the annular inner portion and the annular outer portion of the brim mount, wherein the brim mount top is sized and shaped to be substantially continuously spaced apart from the brim along the length of the brim mount top when the plurality of annular liquid flow barriers are established, the annular inner portion of the brim mount including a first seal ring having a first sloped inner surface sized and shaped to establish the first annular liquid flow barrier between the lid and the cup, the annular outer portion of the brim mount including a third seal ring having a third sloped inner surface sized and shaped to establish the third annular liquid flow barrier between the lid and the brim of the cup, and the annular outer portion of the brim mount including a fourth seal ring having a fourth sloped inner surface sized and shaped to establish the fourth annular liquid flow barrier between the lid and the brim of the cup.

13 . The drink cup lid of claim 12 , wherein the brim mount top is substantially planar and is coupled to the third seal ring.

14 . The drink cup lid of claim 13 , wherein the brim mount top is coupled to the first seal ring.

15 . The drink cup lid of claim 14 , wherein the brim mount further includes an annular connection portion interposed between the brim mount top and the first seal ring and the annular connection portion couples the brim mount top to the first seal ring.

16 . The drink cup lid of claim 15 , wherein the annular connection portion is angled relative to the horizontal axis.

17 . The drink cup lid of claim 12 , wherein the first seal ring and the third seal ring have frustoconical shapes, and the fourth seal ring has a curved shape.

18 . The drink cup lid of claim 11 , wherein the brim mount is arranged with the first seal ring proximate the central closure, the brim mount top interposed between the first seal ring and fourth seal ring, and the third seal ring interposed between the brim mount top and the fourth seal ring.

19 . The drink cup lid of claim 18 , wherein when the drink cup lid is situated with the brim mount top above the first seal ring, the first seal ring extends outwardly away from th
