Abstract
Abstract A cold pack for treating an injury of a subject person. A cooling media, e.g. of BLUE ICE is encased in elongate plastic closed end cylinders. The cylinders are inserted in parallel pockets formed in a wrapper, e.g. made of cloth with the interconnecting cloth material forming flexible hinges between the cylinders. Straps provided on the wrap enable the application of the pre-chilled cold pack to be applied to the injured area of the subject person. The container and plastic partially insulate the cooling media which has the doubly beneficial effect of reducing the cooling effect and extending the life of the cold pack.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
A cold pack for treating an injured area of a subject person comprising; a plurality of rigid closed end cylinders, flexible connecting means interconnecting the cylinders in parallel side-by-side relationship, a cooling media characterized by its cooling property when exposed to ambient temperature, said cooling media encased in said plurality of cylinders to thereby provide a wrap of rigid side-by-side cooling media encased cylinders separated by flexible hinges, said rigid cylinders of a designated size and said flexible connecting means providing hinge connections between said rigid cylinders to permit the cold pack to be formed into a curve for wrapping around the injured area of a subject person.
Claim 2
Dependent Claim
108 words
A cold pack for treating an injured area of a subject person comprising; a plurality of rigid closed end cylinders, flexible connecting means interconnecting the cylinders in parallel side-by-side relationship, a cooling media characterized by its cooling property when exposed to ambient temperature, said cooling media encased in said plurality of cylinders to thereby provide a wrap of rigid side-by-side cooling media encased cylinders separated by flexible hinges, said rigid cylinders of a designated size and said flexible connecting means providing hinge connections between said rigid cylinders to permit the cold pack to be formed into a curve for wrapping around the injured area of a subject person.
Claim 3
Dependent Claim
28 words
A cold pack as defined in claim 1 wherein flexible retaining straps are provided for removably attaching the cold pack to the subject person over the injured area.
Claim 4
Dependent Claim
31 words
A cold pack as defined in claim 2 wherein the flexible retaining straps are a soft cloth that is comfortable in feel when applied to the skin of the subject person.
Claim 5
Dependent Claim
50 words
A cold pack as defined in claim 3 wherein the walls of the cylinders are a plastic material that insulates in part the cooling media within the cylinders and thereby the cooling action of the cooling media that both decreases discomfort and increases the cooling life of the cold pack.
Claim 6
Dependent Claim
60 words
A cold pack as defined in claim 4 wherein the cooling media is permanently encased in the cylinders, a container of flexible material is provided with side-by-side pockets, and the cylinders are removably encased in the pockets of the container enabling individual preparation including cleaning of the cloth material and placement of the cylinders for freezing in a cooling chamber.
Claim 7
Dependent Claim
19 words
A cold pack as defined in claim 5 wherein the cylinders are semi-rigid plastic of chlorinated poly vinyl chloride.
Claim 8
Independent Claim
97 words
A method of treating an injury of a subject person that comprises; enclosing a cooling media in elongate rigid cylinders, enclosing the cylinders in a container of flexible material having side-by-side pockets receiving the cylinders and having flexible hinges between the pockets, said cylinders of a designated size and said hinges compatible therewith to permit forming of the cold pack into a curve, chilling the cooling media within the cylinders to a temperature substantially below room temperature, and wrapping the container with interconnected cylinders of the chilled cooling media around the injured area of a subject person.
Claim 9
Independent Claim
