An object of the present invention is to provide a water absorbent resin powder for a heat-generating element composition, which suppresses the generation of the aggregates derived from the water absorbent resin and the adhesion of the water absorbent resin in the production of a heat-generating element composition.

A present inventive water absorbent resin powder for a heat-generating element composition includes polyacrylic acid (salt)-based water absorbent resin powder which have a bulk specific gravity (specified by JIS K3362) of 0.630 g/cm.sup.3 or less, fluid retention capacity without load (CRC) for a 0.9% by weight aqueous solution of sodium chloride (specified by ERT441.01-2) of 32.0 g/g or less, a weight-average particle diameter (specified by sieve classification) of 250 μm or more, and an amount of a residual glycidyl-based crosslinking agent of 10 ppm or less.

The purpose of the present invention is to provide a heat generator that comprises an adhesive layer containing a volatile component and in which the volatile component is maintained in a stable state during storage, the volatile component is prevented from adhering to a heat-generating section, and it is possible to achieve an excellent warming effect during use. This heat generator comprises: a heat-generating section, an accommodation body that accommodates the heat-generating section and comprises an attachment surface to which an attachment body is attached, an adhesive layer provided to the attachment surface side of the accommodation body, and a release sheet provided to the attachment surface side of the adhesive layer. As a result of including a volatile component in the adhesive layer and providing a metal foil membrane to the release sheet, it is possible to maintain the volatile component in a stable state within the adhesive layer during storage. It is thereby possible to prevent the adhesion of the volatile component to the heat-generating section during storage and to achieve an excellent warming effect during use.

The purpose of the present invention is to provide a heat generator that contains a volatile component and in which the volatile component is stably maintained during storage, the volatile component is prevented from adhering to a heat-generating section, and it is possible to achieve an excellent warming effect during use. This heat generator comprises a heat-generating section (1), an accommodation body (2) for accommodating the heat-generating section (1), an adhesive layer (3) provided to an attachment surface side of the accommodation body (2), and a release sheet (4) provided to the attachment surface side of the adhesive layer (3). As a result of including a volatile component in the adhesive layer (3) and respectively providing gas barrier layers (211), (41) to a first packaging material (21) constituting the attachment surface side of the accommodation body (2) and to the release sheet (4), it is possible to stably maintain the volatile component within the adhesive layer (3) during storage. It is thereby possible to prevent the volatile component from adhering to the heat-generating section (1) during storage and to achieve an excellent warming effect during use.

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 package comprises a mask; and an inactive heater, wherein the mask includes at least one product layer having infused thereon at least one active, and wherein the inactive heater is located in or in proximity to the mask to transfer heat to the mask upon activation of the heater.

Disclosed is an ear-fitting device and a warming device configured to suppress burn of an ear by a warming body. The ear-fitting device according to the disclosure is wearable on an ear and includes a contact portion for contacting a predetermined site of an auricle, and a retainer portion for retaining a warming body capable of warming the predetermined site of the auricle through the contact portion. The retainer portion serves to retain the warming body via the contact portion, in a state where it is spaced from the contact portion.
