Microwavable thermal compress and method and use thereof
First Claim
1. A process of microwave heating a thermal pack comprising the steps of:
- providing a thermal pack comprising a completely sealed envelope constructed from opposed laminate layers, said layers defining an inner chamber within which is disposed a heat transfer material, said chamber being sealed from the exterior of said thermal pack, each of said laminate layers including a pair of co-extensive inner and outer films contacting each other throughout their surface ares, said films being of dissimilar materials;
applying microwave energy to said pack for heating said heat transfer material to a desired temperature; and
selecting the dissimilar materials so that the laminate layers of said thermal pack do not pass said heat transfer material during heating of said thermal pack and do not rupture or separate at the seams thereof when subjected to said microwave energy which is equivalent to the energy developed by a microwave heating device operating at full power of about 750 watts for a period of time greater than about one minute but less than about four minutes.

Abstract
A microwavable thermal pack and a method of heating the pack. The thermal pack is a completely sealed envelope constructed from opposed laminate layers, portions of which are joined by sealed seams. The layers define an inner chamber within which is disposed a heat transfer material. Each of the laminate layers includes a pair of co-extensive inner and outer films contacting each other throughout their surface areas. The films are selected so that the laminate layers of the thermal pack do not pass the heat transfer material during heating of the heat transfer material within the thermal pack which is equivalent to the energy developed by a microwave device operating at full power for a period of time greater than about one minute but less than about four minutes.

8. A process of treating a surface of a body comprising the steps of:
-
(a) utilizing an instant chemical thermal pack including unreactive chemicals; (b) causing said chemicals to react to produce a cold or heated pack; (c) placing said cold or heated pack in contact with said body to transfer heat thereto; (d) removing said pack from said body when the temperature of the pack is substantially at ambient; (e) immediately reheating said pack by microwave energy for a period of time of about 2.0 minutes, and thereafter again placing said heated pack in heat transfer relationship with said body.

9. A microwave thermal pack comprising:
-
a completely sealed envelope construed from opposed laminate layers portions of which are joined by sealed seams, said layers defining an inner chamber within which is disposed a heat transfer material, said chamber being sealed from the exterior of said thermal pack, each of said laminate layers including a pair of co-extensive inner and outer films contacting each other throughout their surface areas, said films being of dissimilar materials; and said dissimilar materials being selected so that the laminate layers of said thermal pack do not pass said heat transfer material during heating of the heat transfer material within said thermal pack and do not rupture or separate at the seams thereof when subjected to microwave energy which is equivalent to the energy developed by a microwave heating device operating at full power of about 750 watts for a period of time greater than about one minute but less than about four minutes. - View Dependent Claims (10, 11, 12, 13, 14, 17, 18)
