Description
本発明は、単位面積あたりの重量が０．１〜０．５ｇ／ｃｍ2であり、含水率が３０〜６０重量％である発熱部が、通気部を有する収容体内に収容されてなるシート状水蒸気発生体であって、
前記収容体における前記通気部の外面に、前記水蒸気発生体を着用者の身体に固定するための固定部が設けられており、該通気部に占める該固定部の面積の割合が１０〜９０％であり、
前記通気部の透湿度が１００〜１０００ｇ／（ｍ2・２４ｈｒ）であり、
前記発熱部は、平均粒径が１０〜５０μｍの粉体（Ａ）と、平均粒径が０．１〜２ｍｍの粉体（Ｂ）とを含有する発熱組成物からなる水蒸気発生体を提供するものである。
The present invention provides a sheet-like shape in which a heat generating part having a weight per unit area of 0.1 to 0.5 g / cm 2 and a moisture content of 30 to 60% by weight is accommodated in a container having a ventilation part. A steam generator,
A fixing part for fixing the water vapor generating body to a wearer's body is provided on the outer surface of the ventilation part in the container, and the ratio of the area of the fixing part to the ventilation part is 10 to 90%. And
The moisture permeability of the ventilation part is 100 to 1000 g / (m 2 · 24 hr),
The heating unit, the average particle diameter of 10~50μm powder (A), provides a steam generator having an average particle diameter of the heat-generating composition containing a powder of 0.1 to 2 mm (B) Is.
具体的には、発熱部２０を構成する発熱組成物の成分として、平均粒径が１０〜５０μｍの粉体（Ａ）と、平均粒径が０．１〜２ｍｍの粉体（Ｂ）との２種以上の粉体を用いている。この範囲の平均粒径を有する粉体（Ａ）及び粉体（Ｂ）を組み合わせて用いることで、発熱組成物を構成する粉体全体の流動特性が良好になる。また、空気の流通性が良好になる。具体的には、平均粒径の大きな粉体である粉体（Ｂ）どうしの間に空間が形成され、その空間の存在によって発熱組成物の流動特性が向上し、また空気の流通性が良好になる。一方、平均粒径の小さな粉体である粉体（Ａ）によって、被酸化性金属の酸化反応が促進される。それらの結果、図３に示すように、通気性部位３５から収容体３０内に流入した空気が、収容体３０内の全域にわたって円滑に流通するようになる。これによって、固定手段３４が位置する部位に存在する発熱部２０（つまり、通気性部位３５から直接空気が供給されない部位に存在する発熱部２０）であっても、発熱反応が均一に生じ、水蒸気が長時間にわたって安定して発生する。
Specifically, as a component of the heat generating composition constituting the heat generating portion 20, a powder (A) having an average particle diameter of 10 to 50 μm and a powder (B) having an average particle diameter of 0.1 to 2 mm Two or more kinds of powders are used. By using a combination of the powder (A) and the powder (B) having an average particle diameter in this range, the flow characteristics of the entire powder constituting the exothermic composition are improved. In addition, air circulation is improved. Specifically, a space is formed between the powders (B), which are powders having a large average particle diameter, and the flow characteristics of the exothermic composition are improved by the presence of the space, and air circulation is good. become. On the other hand, the oxidation reaction of the oxidizable metal is promoted by the powder (A) which is a powder having a small average particle diameter. As a result, as shown in FIG. 3, the air that has flowed into the container 30 from the breathable portion 35 smoothly flows over the entire area of the container 30. As a result, even in the heat generating portion 20 existing in the portion where the fixing means 34 is located (that is, the heat generating portion 20 existing in the portion where air is not directly supplied from the breathable portion 35), the exothermic reaction occurs uniformly, and the water vapor Occurs stably over a long period of time.
