ABSTRACT:
The present invention relates to disposable thermal packs comprising a unified structure having at least one continuous layer of a semirigid material which softens when heated. The thermal packs also comprise a plurality of individual heat cells, which typically comprise an exothermic composition, spaced apart and fixedly attached across the unified structure. The material of the continuous layer or layers provide sufficient rigidity to maintain structural support of the heat cells, to prevent unacceptable stretching of structures of the continuous layer or layers during processing or use of the thermal packs, and to ensure child resistance, while also providing good overall drape characteristics when heated. The thermal packs, when incorporated into body wraps, pads, and the like, provide uniform heat coverage by having excellent conformity with various body forms.
