Abstract
A cooling device includes a tube having an interior formed by a first and second film welded together. The tube has a peelable heat seal connecting a portion of the first film with a portion of the second film. The peelable heat seal divides the interior into a first chamber and a second chamber separated from the first chamber. The interior of the first chamber includes one or more materials which have an endothermic heat of solution in water. The interior of the second chamber contains water. The peelable heat seal has an adhesive force that is overcome by an application of an external force to one of the chambers allowing the material in the first chamber and the water in the second chamber to mix.
