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 having a width between about 80 mils and about 120 mils, and
adjacent bands define a respective sealed pocket of a plurality of sealed pockets in the cavity circumscribing the inner sidewall such that the insulating features maintain a desired temperature of the cold fluid,
the spacer comprises at least a first layer of material and a second layer of material, each of the first layer of material and the second layer of material being a substantially continuous length of material that circumscribes the inner sidewall, the first layer of material is adjacent to the second layer of material, the first layer of material and the second layer of material are comprised of adhesive.

2. The container of claim 1 , wherein the plurality of sealed pockets provide a respective plurality of insulating spaces between the inner sidewall and the outer sleeve.

3. The container of claim 1 , wherein each of the first layer of material and the second layer of material comprises a polymeric material.

4. The container of claim 3 , wherein the adhesive adheres the outer sleeve to the inner sidewall.

5. 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.

6. The container of claim 5 , 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.

7. The container of claim 6 , wherein a portion of the outer sleeve defines a lower edge margin that is folded into the annular recess and into at least partial face-to-face contact with a lower portion of the outer sleeve.

8. The container of claim 7 , wherein the lower edge of the inner sidewall is spaced above an upper edge of the lower edge margin of the outer sleeve such that a gap is defined therebetween.

9. The container of claim 8 , wherein the gap provides a vent for the cavity.

10. The container of claim 1 , wherein an upper portion of the inner sidewall defines a flanged rim, the rim is configured to interengage a container closure.

11. The container of claim 1 , wherein the outer sleeve is spaced apart from the inner sidewall around the entire perimeter of the outer sleeve.

12. The container of claim 1 , wherein respective sealed pockets of the plurality of sealed pockets are annular.

13. The container of claim 1 , wherein each of the first layer of material and the second layer of material extend circumferentially in the cavity.

14. The container of claim 13 , wherein each of the first layer of material and the second layer of material extends around the entire perimeter of the inner sidewall.

15. 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 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 having a width between about 80 mils and about 120 mils, and
adjacent bands define a respective sealed pocket of a plurality of sealed pockets in the cavity circumscribing the inner sidewall for maintaining a desired temperature of the cold fluid,
the spacer comprises at least a first layer of material and a second layer of material, each of the first layer of material and the second layer of material being a substantially continuous length of material that circumscribes the inner sidewall, the first layer of material is adjacent to the second layer of material, the first layer of material and the second layer of material are comprised of adhesive.

16. The sidewall construct of claim 15 , wherein the plurality of sealed pockets provide a respective plurality of insulating spaces between the inner sidewall and the outer sleeve.

17. The sidewall construct of claim 15 , wherein each of the first layer of material and the second layer of material comprises a polymeric material.

18. The sidewall construct of claim 17 , wherein the adhesive adheres the outer sleeve to the inner sidewall.

19. The sidewall construct of claim 15 , wherein an upper portion of the inner sidewall defines a flanged rim, the rim is configured to interengage a container closure.

20. The sidewall construct of claim 15 , wherein the outer sleeve is spaced apart from the inner sidewall around the entire perimeter of the outer sleeve.

21. The sidewall construct of claim 15 , wherein respective sealed pockets of the plurality of sealed pockets are annular.

22. The sidewall construct of claim 15 , wherein each of the first layer of material and the second layer of material extends circumferentially in the cavity.

23. The sidewall construct of claim 22 , wherein each of the first layer of material and the second layer of material extends around the entire perimeter of the inner sidewall.

24. 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 having a width between about 80 mils and about 120 mils, adjacent bands defining a respective sealed pocket of a plurality of sealed pockets in the cavity circumscribing the inner sidewall for maintaining a desired temperature of the cold fluid, the spacer comprises at least a first layer of material and a second layer of material, each of the first layer of material and the second layer of material being a substantially continuous length of material that circumscribes the inner sidewall, the first layer of material is adjacent to the second layer of material, the first layer of material and the second layer of material are comprised of adhesive;
