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.
[ I claim:] [1.] A method of applying heat to a selected object, comprising the steps of:(a) forming a microwavable pad having a liquid and a liquid absorbing means sealed within an envelope in which the absorbing means is compressed within the envelope to less than its non-compressed size;(b) subjecting the pad to microwave radiation; and(c) placing the irradiated pad proximate said object to heat said object.
