An ice pack having a reservoir, a large mouth, and a narrow neck intermediate the mouth and the reservoir. The mouth is tapered to a form funnel to permit the reservoir to be easily filled. A variance in heat exchange is provided between the opposing sides of the ice pack. Hence, one side is significantly colder than the other. Each side includes an identifiable visual characteristic which distinguishes one side from its opposite side, thus enabling an observer to determine which side of the two sides is in communication with a localized region of a patient requiring treatment. A formable element implanted within the structure of the ice pack proximate mouth enables the mouth to be easily formed into the shape of the aforementioned funnel. A safety clip is clamped upon the neck of the ice pack to retain its contents in the reservoir separate from the mouth. The clip includes a safety lock that prevents the two components from inadvertently disengaging if its hinge becomes damaged and broken. A plurality of ties extend laterally of a longitudinal axis of the ice pack and facilitate maintaining the ice pack against the localized region receiving treatment. A method is prescribed in which the opposing sides of the ice pack is heat sealed and simultaneously die cut along the seal, thus eliminating the two step process, namely, sealing and then cutting or tearing.
