Description

  The present invention relates to a facial heating device that applies heat to a desired part of a face such as the eyes.

  Conventionally, in order to improve skin roughness, fine lines, bears, dullness, etc., cosmetics or drugs are applied to the skin, or a sheet-like heating element is attached to the face together with a sheet on which cosmetics or drugs are applied. Techniques that promote the penetration of cosmetics and drugs into the skin using heat generated from the body have been proposed.

  The present applicant has previously proposed a thermal cosmetic device including a sheet-shaped cosmetic material and a sheet-shaped heating device that are separable from each other (see Patent Document 1). According to the thermal cosmetic device described in Patent Document 1, uniform heat can be applied to a desired part of the face, but it is easier to fit to the desired part of the face and there is a demand for further enhancing the feeling of use. There is.

  As a technique for facilitating fitting to a desired site, for example, Patent Document 2 describes a heating element in which a plurality of segmented heating parts each containing a water-containing heating composition are provided at intervals. Patent Document 3 describes a heating element in which a plurality of bag bodies including a heating part are arranged in an island shape.

  However, like the heating element described in Patent Document 2, a plurality of divided heating parts are provided at intervals, or like the heating element described in Patent Document 3, a plurality of bag bodies containing the heating part are included. The so-called cell-type heating elements, which are arranged at intervals, are unlikely to contribute to the heat between the adjacent heating parts, and when the heating value of each heating part varies, it is uniform. It is difficult to apply heat to a desired part of the face.

  The heating element 2 is a part that generates heat using chemical energy. Chemical energy that can be used includes oxidation heat generated by oxidation reaction of oxidizable metals, heat of neutralization of acid and alkali, heat of hydration of inorganic salts (calcium chloride, magnesium chloride, calcium oxide, magnesium oxide, zeolite, etc.) Etc. Among these, since the handleability is good, the calorific value is relatively large, and it is easy to carry and compact, in the first embodiment, the oxidation heat generated by the oxidation reaction of the oxidizable metal. Is used.

  A specific configuration of the heating element 2 using chemical energy is appropriately determined according to the type of chemical energy. For example, when using oxidation heat generated by an oxidation reaction of an oxidizable metal, metal powder (for example, iron, aluminum, zinc, copper, etc.), a salt (for example, sodium chloride, potassium chloride, etc.) Chlorides, alkaline earth metal chlorides such as calcium chloride and magnesium chloride), and a composition containing water. This composition further includes a water retention agent (for example, vermiculite, calcium silicate, silica gel, silica-based porous material, alumina, pulp, wood powder, water-absorbing polymer, etc.), a reaction accelerator (for example, activated carbon, carbon black, graphite). Etc.).

  In the above components of the heating element 2, for example, when sodium chloride is used as the catalyst salt, the time until the maximum temperature of the heating element 2 is reached by controlling the concentration and volume of sodium chloride. Since the (rise time) can be adjusted, sodium chloride is preferably used as the catalyst salt. Specifically, even if the sodium chloride capacity used is controlled, the maximum temperature of the heating element 2 itself cannot be changed greatly, but the concentration of the sodium chloride solution used is, for example, in the range of 5 to 10%. In either case of high concentration or low concentration, the maximum temperature of the heating element 2 is lowered and the rise time can be delayed. In addition, when the density | concentration of sodium chloride solution is too low with 3% or less, an oxidation reaction stops on the way and the maximum temperature will fall. When the concentration of the sodium chloride solution used is the same, the rise time can be delayed by increasing the volume of the sodium chloride solution, and the rise time can be shortened by decreasing the volume. If the volume of the sodium chloride solution is too small, water necessary for heat generation is lost in the middle, and the maximum temperature of the heating element is lowered. If the concentration and volume of sodium chloride are controlled in consideration of such characteristics, the rise time can be controlled, the time for maintaining the maximum temperature can be controlled, and the usability can be improved.

  The heating element 2 containing the above components is in the form of a heating sheet in the first embodiment. Since the heat generating body 2 is in the form of a heat generating sheet, it is possible to prevent unevenness of oxidizable metals and the like during use, and uniform heat generation can be performed. Examples of the heat generating sheet include a sheet-like material obtained by wet papermaking, and a laminate formed by sandwiching heat generating powder with paper or the like. Such a heat generating sheet can be manufactured using, for example, the wet papermaking method described in Japanese Patent Application Laid-Open No. 2003-102761 related to the previous application of the present applicant, or the extrusion method using a die coater.
