Abstract

An insulating device can include an aperture having a waterproof closure which allows access to the chamber within the insulating device. The closure can help prevent any fluid leakage into and out of the insulating device if the insulating device is overturned or in any configuration other than upright. The closure also prevents any fluid from permeating into the chamber if the insulating device is exposed to precipitation, other fluid, or submersed under water. This construction results in an insulating chamber impervious to water and other liquids when the closure is sealed.

Claims

1. A method of forming an insulating device comprising:

forming an inner liner first portion and an outer shell first portion;

securing the inner liner first portion and the outer shell first portion to a sealable closure to form a cap assembly;

forming an inner liner second portion and securing the inner liner second portion to the inner liner first portion to form an inner liner;

forming an outer shell second portion;

rolling a rectangular foam portion to form a first cylindrical foam portion and securing a foam base portion to the first cylindrical foam portion to form a foam assembly;

inserting the foam assembly into the outer shell second portion;

inserting the inner liner into the foam assembly; and

securing the outer shell first portion to the outer shell second portion to form the outer shell.

2. The method of claim 1 wherein the closure is provided with at least one flange and wherein the flange is secured to a bottom surface of the outer shell first portion and a top surface of the inner liner first portion.

3. The method of claim 1 wherein the foam freely floats between the outer shell second portion and the inner liner second portion.

4. The method of claim 1 wherein the closure is configured to be a barrier against fluid penetration in and out of the inner liner.

5. The method of claim 1 wherein the outer shell and inner shell are only connected to the closure and not to the foam assembly.

6. The method of claim 1 further comprising forming waterproof polymer welds between the closure and the inner liner and the closure and the outer shell when the closure, the outer shell, and the inner liner are lying in a flat plane.

7. The method of claim 1 wherein the outer shell is formed of a TPU nylon material.

8. The method of claim 1 wherein the closure has a first flange and a second flange wherein the outer shell is secured to top surfaces of the first flange and the second flange and the inner liner is secured to bottom surfaces of the first flange and the second flange.

9. The method of claim 1 wherein the inner liner is formed from a TPU nylon material.

10. The method of claim 1 wherein the top of the foam assembly has a first perimeter circumference, wherein the bottom of the foam assembly has a second perimeter circumference;

and wherein the first perimeter circumference is equal to the second perimeter circumference.
