Abstract
An electric heating pad is provided, the heating pad having a conductive sheet, the conductive sheet provided with an elongated opening and a perimeter. The conductive sheet is comprised of a flexible and pliable material so that the conductive sheet is capable of following and adhering to the contour of the surface of the human body when applied thereto. A first sheet material, having a seal area disposed on the first sheet material and a perimeter larger than the perimeter of the conductive sheet so as to extend over the conductive sheet to define a sealing edge is provided. A second sheet material, having a seal area disposed on the second sheet material and a perimeter larger than the perimeter of the conductive sheet so as to also extend over the conductive sheet to define a sealing edge is also provided. In this way, when the conductive sheet is placed between the first and second sheet material and when the sealing edges of the first and second sheet material are aligned together, the sealing area and the sealing edges of the first sheet are adhered together with the sealing area and the sealing edges of the second sheet so that the conductive sheet is sealed within the first and second sheet material to define a water-tight pouch.
