The present invention relates to disposable thermal neck wraps having one or more thermal packs comprising a unified structure having at least one continuous layer of semirigid material, which has different stiffness characteristics over a range of temperatures, and a plurality of heat cells, wherein the heat energy is applied to specific areas of the upper back, neck and shoulders. More particularly, the present invention relates to disposable thermal neck wraps having good conformity to user's upper back, neck, and shoulders which provides consistent, convenient, and comfortable heat application.

[ What is claimed is:] [1.] A disposable thermal neck wrap comprising:a) at least one substantially U-shaped piece of flexible material, said piece of flexible material having a first arm portion, a second arm portion, and a central body portion therebetween, such that when said neck wrap is placed on a user, said central body portion is centered at said user's upper back and lower neck and said first and second arm portions lay across said user's shoulders toward said user's chest; andb) one or more thermal packs fixedly attached to said piece of flexible material, said thermal pack having a unified structure comprising at least one continuous layer of a semirigid material having a tensile strength of about 0.7 g/mm.sup.2, or greater, and at least two-dimensional drape at a temperature of about 25.degree. C., and wherein said material has a tensile strength, at a temperature of about 35.degree. C. or greater, substantially less than said tensile strength of said material at about 25.degree. C., and having a plurality of individual heat cells spaced apart and fixed within or to said unified structure of said thermal pack.
