Estimating the term…
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 fixed throughout 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 deter easy access to heat cell contents, while also providing good overall drape characteristics when heated. The thermal packs, when incorporated into body wraps, pads, and the like, provide efficient and effective heat coverage by having excellent conformity with various body forms.
A disposable thermal pack having a unified structure comprising:
A disposable thermal pack having a unified structure comprising at least one continuous layer of material and a plurality of individual heat cells placed into positions fixed within or to said unified structure of said thermal pack, which are sufficiently close and relative to each other, so as to block some or all possible axes across said at least one continuous layer, which otherwise would have passed uninterrupted between said heat cells, through said thermal pack, or select regions thereof.
