Cooling apparel
First Claim
1. Therapeutic sports wearing apparel which comprises a tube of plastics sheet material having an inner nonabsorbent, nonporous smooth faced flexible film layer and an integral outer moisture impervious foam layer composed of particles covering and bonded to said film layer forming a blister-like lattice surface on the film, a refrigerant gel material encased in said tube, and means on the ends of the tube for wrapping the tube directly around the skin of a user to engage the lattice surface with the skin to form therewith pockets trapping moisture from the skin to provide a cool moist zone on the skin, said outer foam layer being effective to meter heat transfer from the gel to the skin preventing cold shock and said lattice surface accommodating evaporation of moisture trapped in the pockets as the cooling capacity of the refrigerant gel diminishes thereby prolonging the cooling capacity of the apparel.

Abstract
Sports wear apparel in the form of wrap around headbands or the like is provided with a tube of plastics sheet material defining pockets filled with refrigerant gel. The tube is composed of a thin plastics material film coated and covered on the outside with a nonabsorbent and nonporous foam integrally bonded on the film. This foam meters heat transfer from the refrigerant gel to the skin of the wearer and provides pockets which trap moisture from the skin and then permit the moisture to evaporate as the cooling capacity of the gel diminishes. This evaporation extends the cooling capacity of the apparel. The ends of the tube are adapted to overlap and are equipped with fasteners such as hook and loop tapes to secure the tube in wrapped around condition on the wearer.

- 1. Therapeutic sports wearing apparel which comprises a tube of plastics sheet material having an inner nonabsorbent, nonporous smooth faced flexible film layer and an integral outer moisture impervious foam layer composed of particles covering and bonded to said film layer forming a blister-like lattice surface on the film, a refrigerant gel material encased in said tube, and means on the ends of the tube for wrapping the tube directly around the skin of a user to engage the lattice surface with the skin to form therewith pockets trapping moisture from the skin to provide a cool moist zone on the skin, said outer foam layer being effective to meter heat transfer from the gel to the skin preventing cold shock and said lattice surface accommodating evaporation of moisture trapped in the pockets as the cooling capacity of the refrigerant gel diminishes thereby prolonging the cooling capacity of the apparel.
- 2. A therapeutic band for wrapping around a portion of the skin of a user which comprises an elongated flexible tube of smooth faced moisture impervious plastics sheet material having an integral outer surface composed of moisture and air impervious nonabsorbent foam with a blister-like lattice of foam particles and pockets between the particles, longitudinally spaced transverse seals along the length of the tube dividing the interior of the tube into a plurality of longitudinally spaced pockets along the length of the tube, refrigerant material in said longitudinally spaced pockets, said transverse seals defining flexible hinges between said longitudinally spaced pockets, tapes of hook and loop fastener material secured to the end margins of the tube cooperating to wrap the tube around the user and compress the outer surface against the skin of the user, said outer surface being effective to prevent cold shock on the skin from the refrigerant material, condense and trap moisture from said skin in said pockets between said foam particles and said pockets between said foam particles being effective to accommodate evaporation of the condensed moisture when the cooling capacity of the refrigerant is dissipated.
