Abstract

A drinking container is provided that can include a lid member and a cup member. The lid member can include a base member and a spout extending up from the base member. The spout can provide a fluid passageway from outside the drinking container to the volume of the cup member so that a child may drink liquid contained within the cup member. When the lid member is removably coupled to the cup member, two or more seals are created around the circumference of the drinking container between the lid member and the cup member to decrease the likelihood of leakage from between the cup member and the lid member when the lid is coupled to the cup member.

First claim

What is claimed is:

1. A drinking container comprising:
a cup member, comprising:
a bottom wall;
a side wall extending up from the bottom wall;
a first rib extending radially inward from the side wall; and
at least one of a ridge and a recess disposed in an interior surface of the side wall;

a lid member removably coupled to the cup member, the lid member comprising:
a base member;
a first flange member extending down from the base member and comprising a first protrusion; and
a second flange member disposed radially outward of the first flange member, extending down from the base member, and comprising a free end,

wherein the first rib abuts the first protrusion and the free end of the second flange member abuts the at least one of the ridge and the recess within the interior volume of the cup member.

2. The drinking container of claim 1 , wherein the first rib extends around a first circumference of the cup member and the first protrusion extends around a first circumference of the lid member, wherein contact between the first rib and the first protrusion creates a first seal between the cup member and the lid member.

3. The drinking container of claim 2 , wherein the free end of the second flange member extends around a second circumference of the lid member that is greater than the first circumference of the lid member.

4. The drinking container of claim 3 , wherein the free end of the second flange member abutting the at least one of the ridge or recess creates a second seal between the cup member and the lid member.

5. The drinking container of claim 1 , wherein the first protrusion is disposed along a free end of the first flange member and extends radially outward from the first flange member.

6. The drinking container of claim 1 , wherein the first flange member is a resilient member and wherein the first rib is configured to generate a radially inward force against the first protrusion.

7. The drinking container of claim 6 , wherein the side wall further comprises:
a first circumference at an upper end of the side wall;
a first outward extending step wall comprising a first end extending radially outward from the upper end of the side wall and a distal second end;
a first upper portion wall comprising a first wall end extending upward from the second end of the first outward extending step wall to a second wall end, the first upper portion wall comprising the first rib and a second circumference greater than the first circumference; and
a second outward extending step wall comprising a first end extending radially outward from the second wall end of the first upper portion wall to a distal second end of the second outward extending step wall, wherein said second outward extending step wall comprises the at least one of a ridge or recess.

8. The drinking container of claim 7 , wherein the cup member further comprises a first rim comprising an inner wall and an outer wall, and wherein the first rim extends upward from the distal second end of the second outward extending step wall.

9. The drinking container of claim 8 , wherein the lid member further comprises a second rim comprising an inner and outer wall, and wherein the second rim has a corresponding shape to the first rim of the cup member.

10. The drinking container of claim 9 , wherein the inner wall of the first rim contacts the inner wall of the second rim, and wherein the outer wall of the first rim contacts the outer wall of the second rim.

11. The drinking container of claim 1 , wherein the first rib is configured to generate a radially inward force on the first protrusion.

12. A lid for a drinking container comprising:
a base member comprising a top surface and an opposing bottom surface;
a spout extending upwards from the top surface of the base member;
a first flange member extending down from the bottom surface of the base member and comprising a first protrusion;
a second flange member disposed radially outward of the first flange member, extending down from the bottom surface of the base member, and comprising a free end; and
a rim comprising an outer wall, wherein the outer wall of the rim is disposed radially outward of the first flange member and the second flange member.

13. The lid of claim 12 , wherein the first flange member defines a first annular wall, wherein the first protrusion extends about the first circumference of the first annular wall and wherein the second flange member defines a second annular wall, wherein the free end of the second flange member extends about the second circumference of the second annular wall.

14. The lid of claim 12 , wherein the first protrusion and the free end of the second flange member comprise discrete flanges that do not continuously extend around the circumference of the lid.

15. A cup for a drinking container comprising:
a bottom wall;
a side wall extending up from the bottom wall;
a first outward extending step wall comprising a first end extending radially outward from the upper end of the side wall and a distal second end;
a first upper portion wall comprising a first wall end and a distal second wall end, the first wall end extending upward from the second end of the first outward extending step wall to the second wall end, the first upper portion wall comprising:
a first rib extending radially inward from the first upper portion wall; and

a second outward extending step wall comprising a first end extending radially outward from the second wall end of the first upper portion wall to a distal second end of the second outward extending step wall, the second outward extending step wall comprising:
a substantially flat and horizontal top surface;
a ridge extending up from a portion of the substantially flat and horizontal top surface of the second outward extending step wall.

16. The cup of claim 15 , wherein the first rib is positioned adjacent to the second wall end of the first upper portion wall.

17. The cup of claim 15 , wherein the side wall comprises a first inner circumference and the first upper portion wall has a second inner circumference and wherein the first inner circumference is less than the second inner circumference.

18. The cup of claim 15 , wherein the first outward extending step wall and the second outward extending step wall are substantially parallel.

19. The cup of claim 15 , wherein the first outward extending step wall has a first radial length and the second outward extending step wall has a second radial length, wherein the second radial length is greater than the first radial length.
