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.

First claim

What is claimed is:

1. A method of forming an insulating device comprising an outer shell having a bottom base support layer, an inner liner, an insulating layer in between the outer shell and the inner liner, the insulating layer comprising sides and a bottom abutting each other, a closure adapted to substantially seal an opening, the closure being substantially waterproof so as to resist liquid from exiting the opening when the insulating device is in any orientation, the method comprising:
forming the inner liner having an inner vessel,
forming the outer shell having the bottom base support layer,
forming the insulating layer;
placing the insulating layer within the outer shell such that the bottom of the insulating layer is unattached to the bottom base support layer, placing the inner liner within the insulating layer; and securing the closure to the outer shell and the inner liner.

2. The method of claim 1 wherein the outer shell and inner liner are only connected to the closure and not to the insulating layer between the outer shell and inner liner.

3. 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.

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

5. The method of claim 1 wherein the insulating layer is a foam layer between the outer shell and the inner liner.

6. The method of claim 1 further comprising forming the insulating layer to be floating freely in between the outer shell and the inner liner.

7. The method of claim 1 wherein the closure is a zipper assembly comprising a plurality of zipper teeth, wherein the zipper teeth are formed of plastic or metal.

8. The method of claim 1 further comprising forming the outer shell and the inner liner from double laminated TPU nylon fabric.

9. The method of claim 1 further comprising forming the insulating layer from closed cell foam.

10. The method of claim 1 further comprising forming the insulating layer from a NBR and a PVC blend.

11. The method of claim 1 wherein at least a portion of the insulating layer is constructed with an EVA foam layer.

12. The method of claim 1 further comprising attaching at least one of a strap or handle to the outer shell.

13. 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.

14. The method of claim 1 further comprising connecting the outer shell and the inner liner to the closure by a polymer weld.

15. The method of claim 1 wherein the sides and the bottom of the insulating layer are secured to each other.
