Heat transfer devices for the scalp

A blank for a heat exchanging head piece for cooling or heating the entire scalp (hair bearing) area of the human head comprising, in combination:

• an elongate, substantially rectangular headband portion adapted to be continuously and circumferentially wrapped around a human head including the forehead, the temple-ear head side zones and the lower back portion of the cranial vault,
• said headband portion having substantially parallel, spaced apart, opposed, upper and lower edges and end edges, the latter substantially at right angles to the former, as well as two free ends at the end edges thereof,
• said headband portion comprising an elongate hollow bag of sealable, liquidtight construction having one end edge thereof open for filling purposes,
• a crown portion of said head piece having a forward edge secured centrally to the substantial center of the upper edge of the headband portion, side edges extending rearwardly from the said forward edge securement and an end edge spaced rearwardly from and substantially parallel to the forward edge,
• said crown portion comprising at least one elongate hollow bag of sealable, watertight construction,
• at least a portion of the end edge of said crown portion opening into said sealable, watertight bag for filling purposes.

• said headband portion having substantially parallel, spaced apart, opposed upper and lower edges and end edges, the latter substantially at right angles to the former, as well as two free ends at the end edges thereof,
• the entire headband portion comprising but a single, continuous, elongate, rectangular hollow bag sealed continuously and circumferentially therearound at the upper, lower and end edges,
• the headband portion being sufficiently long that the end edges thereof abut and somewhat overlie one another when wrapped around a human head,
• said headband portion bag containing materials for heat exchange,
• means engageable between the free ends of said headband portion adapted to secure said free ends together, in contact with one another, to form a continuous headband,
• a crown portion for said head piece having a forward edge secured centrally to the substantial center of the upper edge of the headband portion, side edges extending rearwardly from the said forward edge securement and an end edge spaced rearwardly from and substantially parallel to the forward edge,
• said crown portion divided into two elongate, hollow bags of sealed, liquidtight construction, said bags each containing materials for heat exchange,
• an elongate, grasping tab portion connected to each one of the side edges of the crown portion adjacent the front edge connection thereof,
• means at the end edge of said crown portion adapted to secure said end edge to a part of the said headband portion substantially 180.degree. away from and opposed to the crown portion forward edge securement to the headband portion,
• said latter means comprising a rearward tab extension of the crown portion adapted to lie against the free ends of the headband portion after the end edges of same have been secured to one another and be attached thereto, and
• means for securing the upper edge of the headband portion to the side edges of the crown portion, whereby to form, when the end edges of the headband portion are secured together, the end edge of the crown portion is secured to the headband portion and upper edge of the headband portion are secured to the side edges of the crown portion, a continuous, scalp containing head piece for completely and uniformly heat exchanging the hair bearing zone of the human scalp.
