Abstract

Systems and methods for making an insulating container having at least one cavity in a lid insulating structure or base insulating structure and having at least one vacuum insulated panel disposed within the at least one cavity.

First claim

We claim:

1. An insulating container having a base insulating structure and lid insulating structure that when closed, enclose an internal storage compartment, the insulating container comprising:
a base insulating structure comprising:
a base cavity enclosed by a base outer shell structure and a base inner wall structure, the base inner wall structure including a base collar extending around the perimeter of the base insulating structure, wherein the base outer shell structure further comprises a top flange and a bottom flange, wherein the top flange is engaged within a channel in the base inner wall structure, and wherein the bottom flange is engaged within a channel in the end cap; and
a base insulating portion positioned within the base cavity, the base insulating portion at least partially surrounded by a mass of insulating foam;

a lid insulating structure pivotally engaged with the base insulating structure, the lid insulating structure comprising:
a lid cavity enclosed by a lid outer shell structure and a lid inner wall structure, the lid inner wall structure including a lid collar extending around the perimeter of the lid insulating structure; and
a lid insulating portion positioned within the cavity, the lid insulating portion at least partially surrounded by a mass of insulating foam;

wherein at least one of the base insulating portion and the lid insulating portion comprise at least one vacuum insulated panel.

2. The insulating container of claim 1 , wherein the base insulating portion comprises a first sidewall vacuum insulated panel, a second sidewall vacuum insulated panel, and a 3-piece vacuum insulated panel.

3. The insulating container of claim 2 , wherein the 3-piece vacuum insulated panel comprises a foldable insulating panel having two foldable portions such that the foldable insulating portions are folded to extend around two corners of the base insulating structure.

4. The insulating container of claim 3 , wherein the 3-piece vacuum insulated panel comprises one vacuum insulated panel including two foldable portions.

5. The insulating container of claim 4 , wherein the two foldable portions of the insulating container are compressed such that a thickness of the two foldable portions is less than a thickness of the remaining portions of the 3-piece vacuum insulated panel.

6. The insulating container of claim 5 , wherein the 3-piece vacuum insulated panel includes a cut-out portion.

7. The insulating container of claim 5 wherein the lid insulating portion includes a cut-out portion.

8. The insulating container of claim 1 , further comprising an end cap engaged with a bottom end of the base outer shell structure.

9. The insulating container of claim 1 , wherein the lid outer shell structure further comprises a flange, and wherein the flange is engaged within a channel in the lid collar.

10. The insulating container of claim 9 , further comprising at least one base engagement structure extending from the base collar, wherein the base engagement structure includes a base engagement structure channel that is substantially perpendicular to the channel in the base inner wall structure and wherein the top flange is engaged within the base engagement channel.

11. The insulating container of claim 10 , wherein at least one of a latch, a handle, and a hinge is engaged with the base engagement structure using at least one mechanical fastener.

12. The insulating container of claim 10 , further comprising at least one lid engagement structure extending from the lid collar, wherein the lid engagement structure includes a lid engagement structure channel that is substantially perpendicular to the channel in the lid inner wall structure and wherein the flange of the lid outer wall is engaged within the lid engagement channel.

13. The insulating container of claim 12 , wherein at least one of a latch, a handle, and a hinge is engaged with the base engagement structure and the lid engagement structure using at least one mechanical fastener.

14. An insulating container having a base insulating structure and lid insulating structure that when closed, enclose an internal storage compartment, the insulating container comprising:
a base insulating structure comprising:
a base cavity enclosed by a base outer shell structure composed of stainless steel and a base inner wall structure composed of polyethylene, the base inner wall structure including a base collar extending around the perimeter of the base insulating structure;
an end cap composed of polyethylene engaged with a bottom end of the base outer wall; and
a base insulating portion positioned within the base cavity, the base insulating portion at least partially surrounded by a mass of insulating foam;

a lid insulating structure pivotally engaged with the base insulating structure, the lid insulating structure comprising:
a lid cavity enclosed by a lid outer shell structure composed of stainless steel and a lid inner wall structure composed of polyethylene, the lid inner wall structure including a lid collar extending around the perimeter of the lid insulating structure; and
a lid insulating portion positioned within the cavity, the lid insulating portion at least partially surrounded by a mass of insulating foam;

wherein the base insulating portion and the lid insulating portion each comprise at least one vacuum insulated panel;
wherein the base insulating portion comprises a foldable vacuum insulated panel having at least one foldable portion such that the foldable portion is folded to extend around at least one corner of the base insulating structure;
wherein the foldable portion of the folded vacuum insulated panel is compressed such that a thickness of the foldable portion is less than a thickness of the remaining portions of the foldable vacuum insulated panel; and
wherein the foldable vacuum insulated panel includes a cut-out portion.

15. The insulating container of claim 14 , wherein the insulating foam is polyurethane.

16. An insulating container having a base insulating structure and lid insulating structure that when closed, enclose an internal storage compartment, the insulating container comprising:
a base insulating structure comprising:
a base cavity enclosed by a base outer shell structure composed of stainless steel and a base inner wall structure composed of polyethylene, the base inner wall structure including a base collar extending around the perimeter of the base insulating structure;
an end cap composed of polyethylene engaged with a bottom end of the base outer wall;
a base insulating portion positioned within the base cavity, the base insulating portion at least partially surrounded by a mass of insulating foam; and
at least one base engagement structure extending from the base collar, wherein the base engagement structure includes a base engagement structure channel that is substantially perpendicular to the channel in the base inner wall structure and wherein the top flange is engaged within the base engagement channel

a lid insulating structure pivotally engaged with the base insulating structure, the lid insulating structure comprising:
a lid cavity enclosed by a lid outer shell structure composed of stainless steel and a lid inner wall structure composed of polyethylene, the lid inner wall structure including a lid collar extending around the perimeter of the lid insulating structure; and
a lid insulating portion positioned within the cavity, the lid insulating portion at least partially surrounded by a mass of insulating foam;

wherein the base insulating portion and the lid insulatin
