초록 ▼

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.

대표청구항 ▼

A hot/cold compress for application to an afflicted body portion comprising at least two thermal packs and a holder having at least two pockets disposed side-by-side for receiving said thermal packs, at least one in each pocket, and a strap adapted to encircle said body portion attached at one end to one by said pocket and having releasable fastening means to releasably engage said holder adjacent said pockets, each said thermal pack comprising an absorbent assembly of hydrophilic material comprising a carrier film having a layer of water-soluble adhesive material on at least one surface thereof, a layer of hydrophilic particulate material adhered to said carrier film by said adhesive layer, said particulate hydrophilic material operable upon contact with water to expand in the form of a gel, said carrier film and said particulate material adhered thereto forming the central layer of a multi-layer package, the outer layers of said multi-layer package comprising porous material having flow passages therethrough of a size sufficiently large to afford migration of water through the pores from outside the package into the central layer, and vice versa, and sufficiently small to restrict migration of the gel from the central layer outwardly through the outer layers, said outer layers having a seam extending around their periphery to form a hollow enclosure surrounding said carrier film, said hollow enclosure adapted to be expanded to accommodate the expansion of said particulate material caused by forming a gel upon contact with water, whereby upon contacting said assembly with water, water migrates through said outer layers into said enclosure to cause said particulate matter to form a gel and also to dissolve the adhesive material to free said particulate matter and the gel from adherence to said carrier film.
