Abstract

A device for use as a hot and cold compress comprises a tough flexible envelope of plastic material within which is a gel which maintains a gel-like consistency over a wide temperature range.

Claims

1. A hot and cold compress comprising a tough flexible sealed envelope, and a neutral gel within said envelope, said gel being comprised of a mixture of water, glycerine a thickening agent and a neutralizing agent, the relative weight proportions of the water and the glycerine being about 235.5 parts of the water to about 160 parts of the glycerine, said gel maintaining its gellike consistency over a temperature range of about 0* F. to about 212* F.

2. The compress of claim 1 wherein said thickening agent is acidic and said neutralizing agent is basic.

3. The compress of claim 2 wherein said neutralizing agent is sodium hydroxide.

4. The compress of claim 3 wherein said thickening agent consists of about four parts by weight of Carbopol, and said neutralizing agent consists of about 0.03 parts by weight of sodium hydroxide.

5. The compress of claim 3 wherein said neutral gel further comprises a mold growth inhibiting agent.

6. The compress of claim 5 wherein said mold growth inhibiting agent consists of about 0.64 parts by weight of methyl paraben.
