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.

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.
