Self-heated consumer spa products and applications thereof
The following description relates generally to self-heated consumer spa products heated by means of a prolonged exothermic chemical reaction for various therapeutic and/or spa applications for applying heat to portions of a person's body.
1. An exothermic massage implement, comprising:
a rigid heat conducting vessel comprising a hollow rolling pin having an inner chamber surrounded by a wall with an inner surface and an outer surface, wherein the hollow rolling pin is formed in a substantially cylindrical shape with a plurality of opposed end portions and a plurality of handles operatively connected to respective opposed end portions, wherein the wall comprises at least a portion of the substantially cylindrical shape of the hollow rolling pin; and
a reactant encapsulated completely within a liquid-permeable pouch formed by a liquid permeable membrane, wherein the liquid-permeable pouch is removably positioned inside the inner chamber of the vessel;
wherein a liquid activator is chemically combined with the reactant by permeating the liquid-permeable pouch, wherein the exothermic massage implement is self-heating by chemically combining the reactant and the liquid activator to generate an exothermic reaction that heats and maintains the wall at a substantially constant elevated temperature for a duration of time.
2. The exothermic massage implement of claim 1 , further comprising at least one aperture in the wall.
3. The exothermic massage implement of claim 2 , further comprising a cap engaged with the at least one aperture, the cap having a valve that sequesters the reactant and activator inside the inner chamber while allowing gas flow out of the inner chamber.
4. The exothermic massage implement of claim 1 , wherein the outer surface of the wall includes at least two portions, each with a different texture.
5. The exothermic massage implement of claim 1 , wherein the duration of time is between approximately 15 minutes and 1 hour.
6. The exothermic massage implement of claim 1 , wherein each handle is fixedly connected to or rotatably connected to a respective opposed end portion.
7. The exothermic massage implement of claim 6 , further comprising at least one aperture formed in one of the opposed end portions.
8. The exothermic massage implement of claim 1 , further comprising at least one aperture in the wall between the opposing end portions.
9. The exothermic massage implement of claim 1 , wherein the reactant further comprises perfume particles so that the exothermic reaction produces a fragrant odor.
10. The exothermic massage implement of claim 1 , wherein the rigid heat conducting vessel is constructed from ceramic, resin, glass, or wood.
11. The exothermic massage implement of claim 1 , wherein the permeable membrane of the liquid-permeable pouch is constructed from woven or non-woven materials, paper, cellulose, natural fibers, polyethylene, or polypropylene.
