Abstract

A container for containing a cold fluid. The container includes a sidewall construct that includes an inner sidewall extending at least partially around an interior of the container, an outer sleeve attached to the inner sidewall, and a cavity defined between the inner sidewall and the outer sleeve. The container also includes a closed bottom defining a bottom of the interior of the container, and insulating features that include the cavity and a plurality of annular bands, each annular band of the plurality of annular bands includes a spacer that extends in the cavity from the inner sidewall to the outer sleeve. Adjacent bands define a respective pocket of a plurality of pockets in the cavity such that the insulating features maintain a desired temperature of the cold fluid.

First claim

What is claimed is:

1. A container for containing a cold fluid, comprising:
a sidewall construct comprising an inner sidewall extending at least partially around an interior of the container, an outer sleeve attached to the inner sidewall, and a cavity defined between the inner sidewall and the outer sleeve; and
a closed bottom defining a bottom of the interior of the container,
the container comprises insulating features comprising the cavity and a plurality of annular bands, each annular band of the plurality of annular bands comprises a spacer that extends in the cavity from the inner sidewall to the outer sleeve, the spacer comprises at least a first layer of material applied to a second layer of material adjacent the first layer of material, and
adjacent bands define a respective pocket of a plurality of pockets in the cavity such that the insulating features maintain a desired temperature of the cold fluid.

2. The container of claim 1 , wherein the first layer of material and the second layer of material are comprised of adhesive.

3. The container of claim 1 , wherein the spacer has a width between about 60 mils and about 120 mils.

4. The container of claim 1 , wherein the spacer has a width between about 80 mils and about 120 mils.

5. The container of claim 1 , wherein the spacer has a width of about 80 mils.

6. The container of claim 1 , wherein the spacer comprises a third layer of material adjacent the second layer of material.

7. The container of claim 6 , wherein the first layer of material is in contact with the inner sidewall and the third layer of material is in contact with the outer sleeve.

8. The container of claim 6 , wherein the closed bottom is spaced above the lower edge of the outer sleeve by a distance of least about ⅝ inch and the spacer has a width of about 80 mils.

9. The container of claim 6 , wherein the spacer comprises a fourth layer of material adjacent the third layer of material.

10. The container of claim 9 , wherein the first layer of material is in contact with the inner sidewall and the fourth layer of material is in contact with the outer sleeve.

11. The container of claim 9 , wherein the closed bottom is spaced above the lower edge of the outer sleeve by a distance of least about ⅝ inch and the spacer has a width of about 80 mils.

12. The container of claim 1 , wherein the spacer comprises a substantially continuous length of material that circumscribes the inner sidewall.

13. The container of claim 1 , wherein the closed bottom is spaced above a lower edge of the outer sleeve such that a lower portion of the outer sleeve defines an annular recess below the closed bottom.

14. The container of claim 1 , wherein the closed bottom is spaced above the lower edge of the outer sleeve by a distance of at least about ⅝ inch and the spacer has a width of about 80 mils.

15. The container of claim 13 , wherein the closed bottom comprises a bottom panel and an annular leg extending downwardly from the bottom panel and attached to the inner sidewall, the annular leg is spaced above the lower edge of the outer sleeve.

16. The container of claim 15 , wherein the closed bottom is selectively positioned at the first vertical distance from the outer lower edge or at the second vertical distance from the outer lower edge such that an interior volume of the container is scalable based on the selected position of the closed bottom.

17. The container of claim 16 , wherein the container has a first interior volume when the closed bottom is at the first vertical distance and the container has a second interior volume when the closed bottom is at the second vertical distance, the first vertical distance is less than the second vertical distance such that the first interior volume is greater than the second interior volume.

18. The container of claim 17 , wherein the sidewall construct is oriented at a constant angle relative to a vertical centerline of the container when the closed bottom is positioned at the first vertical distance and at the second vertical distance.

19. A sidewall construct for forming a fluid container for containing a cold fluid, the sidewall construct comprising:
an inner sidewall extending at least partially around an interior of the container;
an outer sleeve attached to the inner sidewall;
a cavity defined between the inner sidewall and the outer sleeve; and
insulating features comprising the cavity and a plurality of annular bands, each annular band of the plurality of annular bands comprises a spacer that extends in the cavity from the inner sidewall to the outer sleeve, the spacer comprises at least a first layer of material applied to a second layer of material adjacent the first layer of material, and
adjacent bands define a respective pocket of a plurality of pockets in the cavity for maintaining a desired temperature of the cold fluid.

20. The sidewall construct of claim 19 , wherein the first layer of material and the second layer of material are comprised of adhesive.

21. The sidewall construct of claim 19 , wherein the spacer has a width between about 60 mils and about 120 mils.

22. The sidewall construct of claim 19 , wherein the spacer has a width between about 80 mils and about 120 mils.

23. The sidewall construct of claim 19 , wherein the spacer has a width of about 80 mils.

24. The sidewall construct of claim 19 , wherein the spacer comprises a third layer of material adjacent the second layer of material.

25. The sidewall construct of claim 24 , wherein the first layer of material is in contact with the inner sidewall and the third layer of material is in contact with the outer sleeve.

26. The sidewall construct of claim 24 , wherein the spacer comprises a fourth layer of material adjacent the third layer of material.

27. The sidewall construct of claim 26 , wherein the first layer of material is in contact with the inner sidewall and the fourth layer of material is in contact with the outer sleeve.

28. A method of forming a container for containing a cold fluid, comprising;
obtaining an inner sidewall and an outer sleeve;
attaching the outer sleeve to the inner sidewall to form a sidewall construct with a cavity defined between the inner sidewall and the outer sleeve, the attaching comprises forming insulating features in the sidewall construct, the insulating features comprise the cavity and a plurality of annular bands, each annular band of the plurality of annular bands comprises a spacer that extends in the cavity from the inner sidewall to the outer sleeve, the spacer comprises at least a first layer of material applied to a second layer of material adjacent the first layer of material, adjacent bands define a respective pocket of a plurality of pockets in the cavity for maintaining a desired temperature of the cold fluid;
