Abstract:
1. A heat activated form fitting hair cap for substantially sealing an area of a body having hair from the environment, comprising: a heat activated shrinkable body having at least one layer of material having a thickness of between approximately 0.25 mil and approximately 8 mil, a distal edge, an inner surface, and an outer surface; the heat activated shrinkable body formed to define an open interior volume bounded by the distal edge and generally sized to receive a portion of a human head and to shrink to conform to the shape of the head when activated by exposure to a heat source thereby creating a substantially liquid-tight seal between the distal edge and the body substantially sealing the portion of the body within the interior volume from the environment; the heat source producing a first predetermined activation temperature between approximately 100 degrees Fahrenheit and 140 degrees Fahrenheit on the outer surface of the heat activated shrinkable body; at least one cap retention means located substantially near the distal edge and thereby ensuring the distal edge substantially conforms to the head prior to activation; wherein the material of the heat activated shrinkable body is substantially moisture resistant and substantially gas impermeable; and the material of the heat activated shrinkable body further having a shrinkage rate between approximately 20 percent and approximately 85 percent.
