Tying neckband heat transfer device

Claim 1

A heat transfer device for cooling or heating the neck area of a user, said device comprising: a main body of flexible fabric material having a length and width; a pocket of flexible fabric material, having a length, width and an interior, and being located lengthwise centrally of the length of said main body; and a heat transfer element dimensioned, configured and adapted to match said pocket interior and including a substance suitable for transferring heat to or from said neck area; said lengths of said main body and pocket being relatively dimensioned for enabling said pocket-matching heat transfer element to be received circumferentially about the back and sides of the neck, yet leaving opposite free ends lengthwise of said main body and away from said pocket, to permit loose tying of said main body of said free ends in front of said neck; and said widths of said main body and said pocket being relatively dimensioned for permitting said main body to be folded widthwise over said pocket to permit optional user-selectable variation of the number of layers of fabric material between said heat transfer element and said neck area.
