The present invention relates to disposable thermal body pads comprising one or more thermal packs having a unified structure of at least one continuous layer of a semirigid material which softens when heated and a plurality of individual heat cells, which typically comprise an exothermic composition, spaced apart and fixedly attached across the thermal pack. 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 pads, and to ensure child resistance, while also providing good overall drape characteristics when heated. The disposable thermal body pads are intended to be attached to a user's clothing on one side and to be held directly against the user's skin on the other side, for pain relief. More particularly, the present invention relates to disposable thermal body pads having good conformity to user's body which provides consistent, convenient and comfortable heat application. Even more particularly, the present invention relates to such disposable thermal body pads intended for relieving menstural pain.

[ What is claimed is:] [1.] A disposable thermal body pad comprising:a) at least one piece of flexible material having a first side, a second side, an upper edge, a lower edge, and one or more thermal packs fixed within or to said at least one piece of flexible material, which comprise a unified str

[ What is claimed is:] [1.] A disposable thermal body pad comprising:a) at least one piece of flexible material having a first side, a second side, an upper edge, a lower edge, and one or more thermal packs fixed within or to said at least one piece of flexible material, which comprise a unified structure of at least one continuous layer, which consists essentially of a coextruded material having a first side of polypropylene and a second side of a low melt temperature copolymer wherein said continuous layer is semirigid at a temperature of about 25.degree. C. and substantially less rigid at a temperature of about 45.degree. C., and a plurality of individual heat cells spaced apart and fixed within or to said unified structure of said thermal pack; andb) a means for releasably attaching said thermal body pad to an inside portion of user's clothing, said means for releasably attaching said thermal body pad being located on said first side of said flexible material so that said second side of said flexible material may be placed directly against a user's body.
