An iron powder for an exothermic composition according to the present invention has a bulk density of 0.3 to 1.5 g/cm.sup.3. Furthermore, an exothermic composition according to the present invention contains the iron powder, a carbon material, a halide salt, and water. Furthermore, an exothermic body production method according to the present invention includes: forming a coated member by coating a base material sheet with a flowable exothermic composition containing the iron powder, a carbon material, and water; and adjusting an amount of moisture in the coated member by removing water from the coated member. Furthermore, the present invention is directed to a production method for the iron powder (an iron powder for an exothermic composition) including: a reducing step of reducing iron oxide to obtain reduced iron; and a step of milling the reduced iron. In the reducing step, the iron oxide is reduced by introducing iron oxide and a solid reductant with a volatile matter content of 10% by mass or more into a heating furnace whose internal portion contains no sulfur gas or is set to an air or inert gas atmosphere, and setting the internal portion to a reducing gas atmosphere through heating under a condition that an ambient temperature of the internal portion is from 900 to 1000° C.

A device comprising a heat-generating component that comprises an alkali metal is provided. The alkali metal in the presence of water at a point of contact of the device undergoes an exothermic reaction to generate heat in situ. The amount of heat generated is proportional to and/or limited by the amount (or moles) of water at the point of contact, and the heat generated is sufficient to achieve an increase in temperature at the point of contact to achieve a therapeutic or beneficial result. In one embodiment, the device is used for reducing sweat production in a subject suffering from excessive sweating or hyperhidrosis. In other embodiments, the device is used to substantially sterilize a surface or render a surface substantially aseptic.

A warming device including a heat generating element that contains a powder of an oxidizable metal, a powder of a carbon material, water, and a powder of a porous material other than the oxidizable metal and the carbon material. The heat generating element is a sheet material, and in the heat generating element, a ratio of the mass content of the water to the mass content of the powder of the oxidizable metal multiplied by one hundred [100 × (water / powder of oxidizable metal)] is from 30 to 270.

A disposable housing including a single-use thermal exchange component can be configured to be mechanically, removably coupled to a receptacle on a cuff positionable around a joint to provide temperature-based therapy to the joint.

This invention provides a heating tool that is capable of significantly suppressing a reduction of an active ingredient contained in an adhesive layer. More specifically, the invention provides a heating tool comprising an exothermic composition containing an oxidation accelerator, an oxidizable metal powder, and water; an active ingredient-containing adhesive layer; and a vapor deposition layer, the exothermic composition being housed in an air-permeable container bag, the vapor deposition layer being disposed between the container bag and the adhesive layer.

A bra including a front with a right cup, a left cup, a right strap, and a left strap, at least one pocket in each of the right and left cups that are shaped and dimensioned to accept warming inserts, a back, and sides connecting the right cup to the back and the left cup to the back.

An object of the present invention is to provide a heat-generating device with which a warm sensation is persistently perceived, and which can effectively exert a heating effect. In a heat-generating device that is used by being attached to skin, (1) a packaging material constituting a skin attachment surface of a housing is formed of a laminated sheet in which at least a moisture absorption layer that absorbs moisture and a moisture barrier layer that blocks penetration of moisture are laminated in this order from the adhesive layer, (2) an adhesive layer is partially provided on a surface of the moisture absorption layer, and (3) a warming agent that allows an enhanced warm sensation to be perceived in the presence of moisture is contained in at least one of the adhesive layer and the moisture absorption layer. This heat-generating device thereby has improved persistence of a perceived warm sensation, and can exert a markedly high heating effect.

A means for controlling the temperature of a warming material includes an air-permeable film or the like. The warming material includes the temperature control means and a heating composition. The temperature control means for controlling the heating temperature of the warming material includes one or more aliphatic compounds that have a melting point of 35-65° C. and a solubility in water (g/100 mL) at 20° C. of 5 or less.
