ABSTRACT:
A thermal pack having a high heat-retention character which may be quickly heated or chilled consisting of an absorbent package having a gel-forming synthetic organic resin in particulate form deposited on an adhesive-coated substrate disposed between a pair of fibrous non-woven porous filter layers and covered on the outside by a pair of paper-like plies of non-woven porous absorbent material. The outside covers are seamed together around their periphery to form a closed envelope.
The thermal pack of the present invention may be positioned in a pouch which is adapted to be held in place over the afflicted area of the body by releasable fastening means. The pack and pouch are formed of porous material which is capable of being heated in microwave oven or cooled in a freezer.
In making the absorbent pack, a predetermined quantity of particulate gel-forming resinous material is deposited on the adhesive surface of the substrate, which is water-soluble so that in use, when the assembly is immersed in water, the gel-forming synthetic organic resinous material is free to expand as a gel and fill the envelope provided by the peripheral seaming.
