Insulating device
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 may also prevent 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 that is substantially impervious to water and other liquids when the closure is sealed.
1. An insulating device comprising:
an outer shell defining a first sidewall;
an inner liner forming a storage compartment;
wherein the outer shell defines a bottom wall extending in a first plane and wherein the inner liner comprises a nylon fabric and is secured to the outer shell in a second plane extending perpendicular to the first plane, and wherein the inner liner is secured to the outer shell by a weld;
an insulating layer comprising a foam layer positioned in between the outer shell and the inner liner, the insulating layer providing insulation for the storage compartment;
an opening configured to allow access to the storage compartment;
a closure adapted to substantially seal the opening, the closure being substantially waterproof so as to resist liquid from exiting the opening when the insulating device is in any orientation; and
a lid assembly attached in at least one location to a body assembly wherein the lid assembly includes an upper inner liner portion comprising a nylon fabric and an upper insulating portion and an upper outer shell portion, and wherein the upper insulating portion is positioned between the upper inner liner portion and the upper outer shell portion.
2. The insulating device of claim 1 wherein the outer shell further comprises a second sidewall and a third sidewall and wherein the opening extends through the first sidewall, the second sidewall, and the third sidewall.
3. The insulating device of claim 1 wherein the insulating device is in a shape of a cuboid.
4. The insulating device of claim 1 wherein the inner liner and the outer shell form a joint and wherein the joint comprises a vent to gases.
5. The insulating device of claim 1 wherein the outer shell comprises one or more handles and wherein a vent is formed adjacent to a location of the one or more handles.
6. The insulating device of claim 1 wherein the closure is substantially waterproof so as to resist liquid from exiting the opening when the insulating device is filled completely with water and is dropped from a distance of six feet.
7. The insulating device of claim 1 wherein the inner liner is formed of a first piece and a second piece and wherein the first piece is joined to the second piece by way of a weld to define a seam and wherein the seam is covered with a seam tape.
8. The insulating device of claim 1 wherein the inner liner is formed by way of injection molding.
9. The insulating device of claim 1 wherein the closure is a zipper and is substantially waterproof and wherein the zipper comprises a pull, the pull being formed of a cloth, string, or rope.
10. The insulating device of claim 1 wherein the temperature of the insulating device when filled with ice of approximately 0.52 lbs. per quart capacity of the insulating device increases from 0° F. to 10° F. in a duration of 0.5 hours to 1.5 hours.
11. The insulating device of claim 1 wherein the temperature of the insulating device when filled with ice of approximately 0.52 lbs. per quart capacity of the insulating device increases from 10° F. to 50° F. in a duration of 22 hours to 28 hours.
12. The insulating device of claim 1 wherein the temperature of the insulating device when filled with ice of approximately 0.52 lbs. per quart capacity of the insulating device increases from 0° F. to 50° F. in a duration of 24 hours to 30 hours.
13. The insulating device of claim 1 wherein the lid assembly and the body assembly together form the inner liner, the insulating layer, and the outer shell.
14. The insulating device of claim 1 wherein the lid assembly includes a handle and a reinforcement layer that is more rigid than the inner liner, the insulating layer, and the outer shell.
15. The insulating device of claim 1 wherein the insulating layer floats between the inner liner and the outer shell.
16. The insulating device of claim 1 wherein the insulating layer is attached to the inner liner or the outer shell.
