Claim 16:
17. A tubular collar, comprising:
a first sheet with an ox-yoke shape including a first curvilinear concave top, a first curvilinear convex bottom, and first and second ends, the first sheet comprising an opening positioned between the first and second ends, and the first sheet comprising a first fastener positioned at the first end or the second end, wherein the first sheet is tapered in a direction from the opening to the first and second ends, wherein the first curvilinear concave top includes a first ridge on the first end, a second ridge on the second end, and a parabolic arc therebetween;
a second sheet with an ox-yoke shape including a second curvilinear concave top affixed to the first curvilinear concave top, a second curvilinear convex bottom affixed to the first curvilinear convex bottom, a third end affixed to the first end, and a fourth end affixed to the second end, a second fastener positioned at the third end or the fourth end, wherein the second sheet is tapered in a direction from a mid-point of the second sheet to the third and fourth ends, wherein the second curvilinear concave top includes a third ridge on the third end, a fourth ridge on the fourth end, and a second parabolic arc therebetween,
wherein the first sheet and the second sheet are affixed together to form an enclosed cavity, wherein the opening provides access to the enclosed cavity through the first sheet, wherein the tubular collar is adapted to receive and maintain a heat transfer medium in the enclosed cavity via the opening, wherein a cross-sectional area of the enclosed cavity is tapered in a direction away from the opening,
wherein the first fastener is releasably attachable to the second fastener such that the tubular collar is configurable between an open configuration and a closed configuration, wherein in the closed configuration, the first fastener is attached to the second fastener and the tubular collar forms a loop sized to be placed around the neck of an individual such that the first and second curvilinear concave tops are adapted to rest upon the shoulders and neck of the individual while the first and second curvilinear convex bottoms extend up the neck of the individual, wherein a cross-sectional distance between where the second curvilinear concave top is affixed to the first curvilinear concave top and where the second curvilinear convex bottom is affixed to the first curvilinear convex bottom is least at the first and second fasteners and increases in a direction away from the first and second fasteners.
