Abstract

An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The opening can be sealed by a closure, the closure having an upper portion with a handle that has a circular curvature equal to the cylindrical portion of the closure. The closure may also have a lower portion that is joined to the upper portion by an injection molded polymer element. The closure may also be in the form of “flip” type of closure such that the lid can be selectably opened or closed by the user by rotating a flip closure into either the opened or closed position. The closure may also be a two-part lid having a lower cap that may be configured to be removably-coupled to the container and an upper cap that may be configured to be removably-coupled to the lower cap.

First claim

What is claimed is:

1. A two-part lid configured to engage a container, the lid comprising:
an upper cap portion comprising:
a first threaded sidewall;
a lower cap portion comprising:
a second threaded sidewall engaged with a central portion and defining an upper opening; and
a third threaded sidewall engaged with the central portion and defining a lower opening;
wherein the first threaded sidewall is configured to removably engage the second threaded sidewall by rotating the upper cap relative to the lower cap, wherein the third threaded sidewall is configured to removably engage a threaded sidewall of a container by rotating the lower cap relative to the container, wherein the third threaded sidewall includes a lower channel extending around a lower area of the third threaded sidewall, wherein the lower channel is configured to retain a gasket, wherein the third threaded sidewall includes an upper channel extending around an upper area of the third threaded sidewall, and wherein the upper channel is configured to retain a gasket; and
wherein a coefficient of friction between the upper cap and the lower cap is less than a coefficient of friction between the lower cap and the container.

2. The two-part lid of claim 1 , wherein a diameter of the upper opening is less than a diameter of the lower opening.

3. The two-part lid of claim 1 , wherein an amount of force necessary to rotate the upper cap relative to the lower cap is less than an amount of force necessary to rotate the lower cap relative to the container.

4. The two-part lid of claim 1 , wherein the number of revolutions required to disengage the upper cap from the lower cap from a fully engaged position is less than the number of revolutions required to disengage the lower cap from the container from a fully engaged position.

5. The two-part lid of claim 1 , wherein the ratio of number of revolutions required to disengage the upper cap from the lower cap from a fully engaged position to the number of revolutions required to disengage the lower cap from the container from a fully engaged position is less than ½.

6. The two-part lid of claim 1 , wherein the number of revolutions required to disengage the upper cap from the lower cap is about ¾ of a revolution.

7. The two-part lid of claim 1 , wherein the upper cap has an outside diameter, wherein the lower cap has an outside diameter, and wherein the outside diameter of the upper cap is substantially similar to the outside diameter of the lower cap.

8. The two-part lid of claim 1 , wherein at least one of the upper cap and the lower cap are formed of a transparent or semi-transparent material.

9. The two-part lid of claim 1 , wherein the upper cap further comprises an integrally molded handle.

10. The two-part lid of claim 9 , wherein the upper cap further comprises:
a frustoconical surface spaced between a circular top surface and a cylindrical surface, the handle being integrally-molded to the frustoconical surface at two diametrically-opposed points.

11. A two-part lid configured to engage a container, the lid comprising:
an upper cap portion comprising:
a first threaded sidewall having threads only on an inner portion of the first threaded sidewall;
a lower cap portion comprising:
a second threaded sidewall having threads on an outer portion of the second threaded sidewall and engaged with a central portion and defining an upper opening; and
a third threaded sidewall having threads on an outer portion of the third threaded sidewall and engaged with the central portion and defining a lower opening;
wherein the first threaded sidewall is configured to removably engage the second threaded sidewall by rotating the upper cap relative to the lower cap and wherein the third threaded sidewall is configured to removably engage a threaded sidewall of a container by rotating the lower cap relative to the container;
wherein a diameter of the upper opening is less than a diameter of the lower opening;
wherein the upper opening and the lower opening are collinear;
wherein the second threaded sidewall is above the central portion and the third threaded sidewall is below the central portion;
wherein the third threaded sidewall includes a lower channel extending around a lower area of the third threaded sidewall, and wherein the lower channel is configured to retain a gasket; and
wherein the third threaded sidewall includes an upper channel extending around an upper area of the third threaded sidewall, and wherein the upper channel is configured to retain a gasket.

12. The two-part lid of claim 11 , wherein the number of revolutions required to disengage the upper cap from the lower cap from a fully engaged position is less than the number of revolutions required to disengage the lower cap from the container from a fully engaged position.

13. The two-part lid of claim 12 , wherein the upper cap has an outside diameter, wherein the lower cap has an outside diameter, and wherein the outside diameter of the upper cap is substantially similar to the outside diameter of the lower cap.

14. The two-part lid of claim 13 , wherein an amount of force necessary to rotate the upper cap relative to the lower cap is less than an amount of force necessary to rotate the lower cap relative to the container.

15. The two-part lid of claim 14 , wherein a coefficient of friction between the upper cap and the lower cap is less than a coefficient of friction between the lower cap and the container.

16. The two-part lid of claim 15 , wherein the ratio of number of revolutions required to disengage the upper cap from the lower cap from a fully engaged position to the number of revolutions required to disengage the lower cap from the container from a fully engaged position is less than ½.

17. The two-part lid of claim 16 , wherein the number of revolutions required to disengage the upper cap from the lower cap is about ¾ of a revolution.

18. The two-part lid of claim 17 , wherein at least one of the upper cap and the lower cap are formed of a transparent or semi-transparent material.

19. The two-part lid of claim 18 , wherein the upper cap further comprises:
an integrally molded handle; and
a frustoconical surface spaced between a circular top surface and a cylindrical surface, the handle being integrally-molded to the frustoconical surface at two diametrically-opposed points.
