Abstract
A therapeutic pad for heating or cooling has a liquid absorbent to prevent liquid leakage in the event the sealed envelope of the pad is ruptured. The method of forming the pad includes vacuuming the thermoplastic envelope prior to sealing. The pad can be used alone or with a comforter to provide warmth or to remove heat from the body of the user.
