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 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.

Abstract: An insulating device can include a body assembly and a lid assembly where an insulating layer is connected to both the body assembly and the lid assembly. An aperture with a closure is formed between the body assembly and lid assembly to form a storage compartment. The insulating layer on the lid assembly may extend beyond the closure when the closure is sealed. The insulating layer on the lid assembly may have an insulating ring that has an increased thickness around its perimeter.

Abstract: A closure having a first flange with first engagement mechanism and a second with a second engagement mechanism disposed between the first end and the second end. The first engagement mechanism configured to engage the second engagement mechanism. A slider configured to selectively engage the first engagement mechanism and the second mechanism when moved in a first direction and disengage the first engagement mechanism from the second engagement mechanism when moved in a second direction. The closure is substantially watertight in the closed position.
