Abstract
A disposable thermal pad comprises a substantially planar laminate structure having a first side and a second side and a plurality of heat generating cells embedded between the first and the second sides. The plurality of heat generating cells each are spaced apart and fixedly attached to the laminate structure. The laminate structure has means for providing oxygen permeability to each of the plurality of heat generating cells. The means for providing oxygen permeability is located entirely on the first side of the laminate structure. The disposable thermal pad also comprises means for releasably attaching the thermal pad to an inside portion of a user's clothing. The means for releasably attaching is also located on the first side of the laminate structure so that the second side of the thermal pad may be placed directly against a user's body.
