Insulating container
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.
1. An insulating container having a storage compartment comprising:
an outer shell, the outer shell comprising webbing to form one or more loops configured to attach items to the insulating container and a loop patch configured to attach additional items to the insulating container, and one or more reinforcement areas or patches for supporting the webbing and the loop patch, an elongated base support ridge for supporting the insulating container on a surface;
an inner liner defining a side wall extending in a vertical direction, and a bottom wall, where the side wall, and bottom wall form the storage compartment, the inner liner side wall being formed of a rectangular sheet of material, the inner liner being configured to maintain a liquid in the storage compartment and to prevent any liquid from entering into the storage compartment once the container is sealed;
a foam layer positioned in between the outer shell and the inner liner, the foam layer providing insulation wherein the foam layer comprises a continuous integral rectangular sheet encircling and completely surrounding the inner liner side wall vertically;
an opening configured to allow access to the storage compartment; and
a closure adapted to substantially seal the opening, the closure being substantially waterproof to maintain the liquid for a period of greater than 30 minutes therein when inverted and at least a half of a volume of the storage compartment is filled with the liquid and wherein the closure is watertight up to 2 to 14 psi above atmospheric pressure.
2. The insulating container of claim 1 wherein the outer shell has a top portion and wherein the top portion of the outer shell has a first perimeter circumference, wherein the outer shell has a bottom portion, the bottom portion of the outer shell has a second perimeter circumference, and wherein the first perimeter circumference is equal to the second perimeter circumference.
3. The insulating container 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.
4. The insulating container of claim 1 wherein the outer shell and the inner liner are made of a double laminated TPU nylon fabric.
5. The insulating container of claim 1 wherein the foam layer is made of a NBR and a PVC blend.
6. The insulating container of claim 1 wherein at least a portion of the foam layer is constructed with an EVA foam layer.
7. The insulating container of claim 1 wherein the outer shell further comprises at least one ring for securing the insulating container.
8. The insulating container of claim 1 wherein the outer shell is connected to the closure by a polymer weld.
9. The insulating container of claim 1 wherein one or more of the strap, loop patch or webbing are attached to the outer shell by a thread and wherein the thread does not extend into the foam layer.
10. The insulating container of claim 1 wherein a heat gain rate of the insulating container is approximately 1.0 to 1.5 degF/hr.
11. The insulating container of claim 1 further comprising at least one handle, wherein the at least one handle is configured to support 100 lbs. to 300 lbs. of weight for 1 to 10 minutes without showing signs of failure.
12. The insulating container of claim 1 wherein the insulating container is configured to withstand 35 lbs. to 100 lbs. of puncture force.
13. The insulating container of claim 1 wherein the foam layer is floating freely in between the outer shell and the inner liner.
14. The insulating container of claim 1 wherein the foam layer is unattached to the outer shell and the inner liner.
15. The insulating container of claim 1 further comprising a base support layer.
16. The insulating container of claim 1 further comprising a logo or name molded or embossed directly into a base of the insulating container.
17. The insulating container of claim 1 further comprising a shoulder strap.
18. The insulating container of claim 1 further comprising a cold retention time of greater than 11 hours.
19. The insulating container of claim 1 wherein the foam layer comprises a sidewall portion and a base portion.
20. The insulating container of claim 1 wherein the foam layer is rolled to completely surround the inner liner sidewall.
