就製品管理方面、及效率良好地表現出香味之觀點而言，較佳為於袋體30之內側至發熱部10之間施加香料組合物。 作為於發熱部10與袋體30之間施加香料組合物之具體之方法，例如，可使袋體30之內側面直接含浸香料組合物，亦可如圖1所示般於其間配置藉由香料組合物對片材料賦香而成之賦香片15而施加，亦可將對粉體或油脂之載體賦香所獲得之粉末香料或糊狀之賦香物製成片狀而施加於其間。 於使用賦香片15之情形時，具體而言，可藉由與袋體30之內側面鄰接地配置而施加，亦可藉由接著劑將賦香片15接著於袋體30之內側面而施加。From the viewpoint of product management and efficient expression of fragrance, it is preferable to apply the fragrance composition from the inside of the bag body 30 to the heat generating portion 10. As a specific method of applying the fragrance composition between the heat generating portion 10 and the bag body 30, for example, the inner surface of the bag body 30 may be directly impregnated with the fragrance composition, or may be disposed therebetween as shown in FIG. The composition is applied to the flavoring sheet 15 obtained by flavoring the sheet material, and the powder flavor or paste flavoring obtained by flavoring the powder or oil carrier can also be applied in the form of a sheet. In the case where the fragrance sheet 15 is used, specifically, it may be applied by being disposed adjacent to the inner surface of the bag body 30, or may be applied by adhering the fragrance sheet 15 to the inner surface of the bag body 30.

再者，於本說明書中，所謂「鄰接地配置」意指處於附近但未必接觸之狀態，即可接觸亦可不接觸之狀態。In addition, in this specification, the "adjacent configuration" means a state that is nearby but not necessarily in contact, and may be in a state of being in contact or not in contact.

賦香片15較佳為包含紙、不織布、織布等含有纖維材料之片材料、或多孔質性膜等具有吸濕/吸油性之片材料。 片材料之材質例如可設為絲綢、棉、羊毛、及纖維素等天然纖維、聚醯胺、聚烯烴、聚酯等合成纖維。 其中，就使用溫熱器具1時保持良好之芳香與發熱特性之平衡，並且可實現溫熱器具1之輕量化之方面而言，較佳為含有纖維素之紙、例如吸水紙。The flavoring sheet 15 is preferably a sheet material containing fibrous materials such as paper, non-woven fabric, and woven fabric, or a sheet material having moisture absorption / oil absorption properties, such as a porous film. The material of the sheet material can be, for example, natural fibers such as silk, cotton, wool, and cellulose, synthetic fibers such as polyamide, polyolefin, and polyester. Among them, in terms of maintaining a good balance between aroma and heat generation characteristics when using the warming device 1 and achieving weight reduction of the warming device 1, cellulose-containing paper such as absorbent paper is preferred.

於袋體30內，發熱部10如圖1所示，可進一步收容至收容體20中而構成發熱體14。收容體20之至少一部分具有通氣性。於圖1所示之例中，具體而言，收容體20具有使第1收容體片20a與第2收容體片20b之周緣部互相接合所形成之形狀。收容體20中，相較於接合之周緣部，內側之部分成為非接合狀態，藉此形成收容發熱部10之單一之空間。In the bag body 30, as shown in FIG. 1, the heat generating portion 10 can be further accommodated in the housing body 20 to constitute the heat generating body 14. At least a part of the housing body 20 is breathable. In the example shown in FIG. 1, specifically, the storage body 20 has a shape formed by joining peripheral edges of the first storage body piece 20 a and the second storage body piece 20 b. In the accommodating body 20, the inner portion becomes non-joined compared to the joined peripheral edge portion, thereby forming a single space for accommodating the heating portion 10.

於本發明中，亦可使第2收容體片20b之通氣度大於第1收容體片20a之通氣度。藉此，可進一步抑制發熱部10中之吸水劑對香料組合物之影響。即，較佳為將第2收容體片20b之通氣度設為第1收容體片20a之通氣度之2倍以上，更佳為設為5倍以上，進而較佳為設為10倍以上。In the present invention, the air permeability of the second container body piece 20b may be greater than the air permeability of the first container body piece 20a. This can further suppress the influence of the water-absorbing agent in the heat generating portion 10 on the fragrance composition. That is, it is preferable to set the air permeability of the second storage body sheet 20b to be twice or more the air permeability of the first storage body sheet 20a, more preferably to 5 times or more, and still more preferably to 10 times or more.

第1收容體片20a可以可使空氣及水蒸汽透過之方式具有通氣性。另一方面，第2收容體片20b與第1收容體片20a相比可為難通氣性或非通氣性。於第2收容體片20b為難通氣性之情形時，較佳為將該第2收容體片20b之通氣度設為5,000秒/100 ml以上，更佳為設為10,000秒/100 ml以上，進而較佳為設為20,000秒/100 ml以上，進而較佳為設為30,000秒/100 ml以上。另一方面，第1收容體片20a之通氣度不論第2收容體片20b為非通氣性或難通氣性，均較佳為1,000秒/100 ml以上且50,000秒/100 ml以下。The first accommodating body sheet 20a may have air permeability so that air and water vapor can pass through. On the other hand, the second container body piece 20b may be less ventilable or non-ventilable than the first container body piece 20a. When the second container sheet 20b is difficult to ventilate, it is preferable to set the ventilation degree of the second container sheet 20b to 5,000 seconds / 100 ml or more, more preferably to 10,000 seconds / 100 ml or more, and It is preferably 20,000 seconds / 100 ml or more, and more preferably 30,000 seconds / 100 ml or more. On the other hand, the degree of ventilation of the first container body piece 20a is preferably 1,000 seconds / 100 ml or more and 50,000 seconds / 100 ml or less regardless of whether the second container body piece 20b is non-ventilable or difficult to ventilate.

作為第1收容體片20a及第2收容體片20b之具體之材料，就支配通氣度且防止粉體漏出等方面而言，可適宜地使用熔噴不織布或透濕性膜、通氣性片、難通氣性片。再者，作為透濕性膜，例如可使用將熱塑性樹脂及與該樹脂不具有相溶性之有機或無機填料之熔融混練物成形為膜狀，並進行單軸或雙軸延伸所獲得之具有微細之多孔質結構者。As specific materials of the first container body sheet 20a and the second container body sheet 20b, in terms of controlling air permeability and preventing powder leakage, a melt-blown non-woven fabric, a moisture-permeable film, a breathable sheet, Difficult ventilation film. In addition, as the moisture-permeable film, for example, a thermoplastic resin and a melt-kneaded product of an organic or inorganic filler that does not have compatibility with the resin can be formed into a film shape and uniaxially or biaxially stretched to obtain fine particles. The porous structure.

作為通氣性片，可使用樹脂製之多孔質片或具有通氣孔之樹脂製之片材，例如可使用聚乙烯、聚丙烯、乙烯-乙酸乙烯酯共聚物等。 作為樹脂製之多孔質片，具體而言，為將熱塑性樹脂及與該樹脂不具有相溶性之有機或無機填料之熔融混練物成形為膜狀，並進行單軸或雙軸延伸所獲得者，較佳為成為微細之多孔質結構者、作為具有通氣孔之樹脂製之片材而以針等於非通氣性片或難通氣性片設置微細孔者、或者以針等進一步於上文所述之通氣性片設置微細孔者。 通氣性片之厚度較佳為5 μm以上且200 μm以下。As the breathable sheet, a resin-made porous sheet or a resin-made sheet having a vent hole can be used, and for example, polyethylene, polypropylene, ethylene-vinyl acetate copolymer, etc. can be used. As a porous sheet made of resin, specifically, a thermoplastic resin and a melt-kneaded product of an organic or inorganic filler that does not have compatibility with the resin are formed into a film shape and uniaxially or biaxially stretched, It is preferable to be a microporous structure, as a resin sheet having vent holes, and to provide micropores with a needle equal to a non-ventilating sheet or a hard-ventilating sheet, or to use a needle or the like as described above The ventilating sheet is provided with fine holes. The thickness of the breathable sheet is preferably 5 μm or more and 200 μm or less.

作為難通氣性片，為實質上不使氧透過者即可，例如可使用選自聚乙烯、聚丁二烯等聚烯烴、聚氯乙烯、聚偏二氯乙烯、聚酯、聚醚、聚碸及聚醯胺之1種或2種以上。難通氣性片之厚度較佳為5 μm以上且200 μm以下。 第1收容體片20a及第2收容體片20b可包含1片片材，亦可包含複數片片材之積層體。The hardly breathable sheet may be one that does not substantially allow oxygen to pass through. For example, polyolefins selected from polyethylene and polybutadiene, polyvinyl chloride, polyvinylidene chloride, polyester, polyether, and polyether can be used. One or more types of tarnish and polyamide. The thickness of the hard-to-ventilate sheet is preferably 5 μm or more and 200 μm or less. The first storage body sheet 20a and the second storage body sheet 20b may include one sheet or a laminate of plural sheets.

香料組合物如上文所述，較佳為施加至發熱部10與袋體30之內側之間，更佳為施加至收容體20與袋體30之內側之間。又，進而較佳為將香料組合物施加至收容體20之外側面。若於香料組合物與發熱部10之間介置第2收容體片20b，則香料組合物與發熱部10之距離變遠，因此可以物理方式抑制吸水劑等對香味或發熱特性之影響。As described above, the fragrance composition is preferably applied between the heating portion 10 and the inside of the bag body 30, and more preferably between the container 20 and the inside of the bag body 30. Furthermore, it is more preferable to apply the fragrance composition to the outer surface of the container 20. When the second container sheet 20b is interposed between the fragrance composition and the heat generating portion 10, the distance between the fragrance composition and the heat generating portion 10 becomes longer, so that the influence of the water absorbing agent or the like on the fragrance or heat generating characteristics can be physically suppressed.

作為將香料組合物施加至收容體20之外側面之具體例，可將香料組合物直接塗佈於收容體20之外側面之片材。再者，亦可將收容體20之外側面之片材設為與賦香片相同者，並且對該片材施加香料組合物。即，亦可使用接著劑或熱熔等方法於第2收容體片20b之外側面積層與賦香片相同之片材，而將收容體20之外側面之片材設為與賦香片相同者。藉此，香料組合物與發熱部10之距離變遠，因此不會發生片材引起之溫度妨礙而可賦予充分之溫熱效果，並且賦香較容易，香料組合物之香味濃郁性變得極高，亦可進一步有效地抑制香味之變化。於使用賦香片15之情形時，較佳為如圖示般與收容體20鄰接地配置。As a specific example of applying the perfume composition to the outer surface of the container 20, the perfume composition may be directly applied to the sheet on the outer surface of the container 20. In addition, the sheet on the outer side of the container 20 may be the same as the flavoring sheet, and a fragrance composition may be applied to the sheet. That is, it is also possible to use a method such as an adhesive or hot-melt on the outer surface layer of the second container sheet 20b to have the same sheet as the flavor sheet, and to set the sheet on the outer surface of the container 20 to be the same as the flavor sheet. Thereby, the distance between the fragrance composition and the heat generating portion 10 becomes longer, so that no temperature obstruction caused by the sheet can occur and a sufficient warming effect can be imparted, and the fragrance is easier to impart, and the fragrance richness of the fragrance composition becomes extremely High, can further effectively suppress the change of fragrance. When the fragrance-enhancing sheet 15 is used, it is preferably arranged adjacent to the container 20 as shown in the figure.

於使第1收容體片20a位於靠近皮膚等適用部位之側，使第2收容體片20b位於遠離適用部位之側之情形時，藉由將賦香片15配置於位於遠離適用部位之側之第2收容體片20b側的外側面、或將香料組合物施加於外側面，可提高使用時之輕便性，並且對適用部位賦予充分之溫熱效果，同時達成良好之香味濃郁性。When the first accommodating body sheet 20a is located close to the application site such as the skin, and the second accommodating body sheet 20b is positioned away from the application site, by disposing the fragrance sheet 15 on the side away from the application site 2 The outer surface of the container sheet 20b side, or the application of the fragrance composition to the outer surface, can improve the portability during use, and give a sufficient warming effect to the application site, while achieving good flavor richness.

溫熱器具1較佳為於其使用前以具有氧阻隔性之包裝材(未圖示)將其整體密封。It is preferable that the warming device 1 is sealed in its entirety with a packaging material (not shown) having oxygen barrier properties before use.

繼而，對利用溫熱器具1獲得之效果進行說明。 溫熱器具1具有：發熱部10，其具備被氧化性金屬、吸水劑及水；及袋體30，其至少一部分具有通氣性，且收容發熱部10，該溫熱器具1係藉由香料組合物而賦香，該香料組合物含有(A)為選自倍半萜烴及其衍生物之1種或2種以上且不具有雙環[7.2.0]十一烷骨架之化合物、及(B)具有萜骨架且碳數為10～12之含氧化合物。於溫熱器具1中，成分(A)之含量相對於被氧化性金屬100質量份為0.1質量份以上且0.8質量份以下，成分(A)相對於成分(B)之質量比率((A)/(B))為0.1以上且4以下。 此處，成分(A)主要作為可表現出森林風格之芳香之香氣成分而為人所知，但本發明者等人發現其係對溫熱器具1之剛開始使用後之溫度上升造成影響之香味之群。即，本發明者等人首次發現，若僅以成分(A)對先前之溫熱器具賦香，則製造溫熱器具1後，直至使用前期間，溫熱器具之發熱特性降低。 與此相對，溫熱器具1係將成分(A)與成分(B)加以組合而成者。即，作為可於不大幅改變香味品質之情況下抑制成分(A)對溫熱器具1之剛開始使用後之溫度上升的影響之香味之群而特定出成分(B)，藉由成分(A)與成分(B)之組合，而獲得良好之發熱特性。 此外，藉由適當地控制該等之含量，可抑制溫熱器具1之發熱特性之降低，於使用溫熱器具1時可獲得良好之芳香，並且穩定地保持良好之發熱特性。該機制之詳細尚不明確，推測製造溫熱器具1後，直至使用前期間，成分(A)與發熱部10產生相互作用，由此發熱特性降低，推測藉由添加成分(B)，而取得成分(A)、成分(B)及發熱部10之間之平衡，不會對香味品質造成較大影響而可獲得良好之發熱特性。再者，本發明者等人確認具有雙環[7.2.0]十一烷骨架之化合物於製造溫熱器具1後，直至使用前期間，與發熱部10幾乎無相互作用。 此處，溫熱器具1之所謂良好之發熱特性係指於使用溫熱器具1時，良好地發揮出發熱部10之伴隨空氣中之氧引起之氧化反應的發熱，剛開始使用後之溫度上升充分，發熱部10之表面最高達到溫度之降低得以抑制。Next, the effect obtained by the heating appliance 1 is demonstrated. The heating appliance 1 includes: a heating part 10 including an oxidized metal, a water-absorbing agent, and water; and a bag body 30, at least a part of which is breathable, and houses the heating part 10, the heating device 1 is combined by a fragrance This fragrance composition contains (A) one or more compounds selected from sesquiterpene hydrocarbons and their derivatives and does not have a bicyclic [7.2.0] undecane skeleton, and (B) ) Oxygenated compounds having a terpene skeleton and a carbon number of 10-12. In the heating appliance 1, the content of the component (A) is 0.1 parts by mass or more and 0.8 parts by mass or less with respect to 100 parts by mass of the oxidizable metal, and the mass ratio of the component (A) to the component (B) ((A) / (B)) is 0.1 or more and 4 or less. Here, the component (A) is mainly known as an aroma component that can express a forest-like aroma, but the inventors and others found that it affects the temperature rise immediately after the heating appliance 1 is used. Group of fragrances. That is, the inventors of the present invention discovered for the first time that if the previous warming device is flavored with only the component (A), the heat-generating characteristics of the warming device decrease after the warming device 1 is manufactured and before use. On the other hand, the heating appliance 1 is a combination of component (A) and component (B). That is, the component (B) is identified as a group of fragrances that can suppress the effect of the component (A) on the temperature rise immediately after use of the heating appliance 1 without significantly changing the flavor quality, and the component (A ) In combination with component (B) to obtain good heat generation characteristics. In addition, by appropriately controlling these contents, it is possible to suppress the decrease in the heat-generating characteristics of the warming device 1, obtain good aroma when using the warming device 1, and stably maintain the good heat-generating characteristics. The details of this mechanism are not clear. It is presumed that after the heating device 1 is manufactured, until the period before use, the component (A) interacts with the heat-generating portion 10, and thus the heat-generating characteristics are degraded. It is presumed that the component (B) is obtained The balance between the component (A), the component (B), and the heat generating portion 10 does not greatly affect the flavor quality, and good heat generating characteristics can be obtained. Furthermore, the present inventors confirmed that the compound having a bicyclic [7.2.0] undecane skeleton has almost no interaction with the heat-generating portion 10 until the period before use after manufacturing the warming device 1. Here, the so-called good heat generation characteristic of the heating appliance 1 means that when the heating appliance 1 is used, the heat generated by the oxidation reaction caused by the oxygen in the air in the starting heat section 10 is exerted well, and the temperature rise immediately after the start of use Sufficiently, the reduction in the maximum temperature of the surface of the heating portion 10 is suppressed.

又，為了如上述般不對香味品質造成較大之影響而抑制成分(A)對溫熱器具1之剛開始使用後之溫度上升的影響，溫熱器具1亦可為含有成分(A)及成分(B)並且滿足以下之條件者。 條件：將溫熱器具1裝入隔氧性袋中，於脫氣狀態下以50℃處理30天後，於室溫20℃、濕度60%之大氣壓下將溫熱器具1於空氣中打開時之發熱部10之表面最高達到溫度為54℃～72℃。In addition, in order to suppress the influence of the component (A) on the temperature rise immediately after the heating appliance 1 is used without causing a great influence on the fragrance quality as described above, the heating appliance 1 may also contain the component (A) and the component (B) And meet the following conditions. Conditions: Put the heating appliance 1 in an oxygen-proof bag, and treat it at 50 ° C for 30 days in a degassed state, then open the heating appliance 1 in the air at 20 ° C at room temperature and 60% humidity. The maximum temperature of the surface of the heating portion 10 is 54 ° C to 72 ° C.

溫熱器具1藉由滿足上述條件，亦可如下所述，獲得以優異之平衡性獲得芳香與發熱特性之特有之保持作用：於製造溫熱器具1後，直至使用前期間，抑制發熱特性降低，於使用溫熱器具1時，可獲得良好之芳香，且可對皮膚賦予充分之溫熱。 該理由之詳細尚不明確，本發明者等人反覆研究過程中發現，於溫熱器具1具有成分(A)與成分(B)之情形時，若於50℃下處理30天後之發熱部10之表面最高達到溫度成為適當之範圍內，則不會對溫熱器具1之發熱特性造成較大之影響，且可自溫熱器具1獲得所需之芳香。因此，進行了研究，結果發現，於溫熱器具1滿足於50℃下處理30天後，將溫熱器具1於室溫20℃、濕度60%之大氣壓下於空氣中打開時之發熱部10之表面最高達到溫度為54℃～72℃之條件之情形時，可獲得上述特有之保持作用，而以上述條件作為表示特有之保持作用之指標。 又，為了滿足上述條件，重要的是研究溫熱器具1之製法。作為製法上之研究，除了具有成分(A)及成分(B)以外，可列舉對其賦香量、被氧化性金屬及吸水劑之平均粒徑、被氧化性金屬、吸水劑及水等之含量、以及發熱部10之製造方法等加以調整並適當地組合。By satisfying the above conditions, the heating appliance 1 can also obtain the unique holding effect of obtaining aroma and heat generation characteristics with excellent balance as follows: after the heating appliance 1 is manufactured, until the period before use, the reduction in heat generation characteristics is suppressed When using the warming device 1, a good fragrance can be obtained and sufficient heat can be given to the skin. The details of this reason are not clear. The inventors and others have repeatedly researched that when the heating device 1 has the component (A) and the component (B), if the heating part is treated at 50 ° C for 30 days The highest temperature of the surface of 10 is within an appropriate range, it will not have a great influence on the heating characteristics of the heating appliance 1, and the desired aroma can be obtained from the heating appliance 1. Therefore, a study was conducted, and as a result, it was found that the heating part 10 when the heating device 1 was opened in the air at room temperature of 20 ° C. and humidity of 60% at atmospheric pressure after 30 days of treatment at 50 ° C. When the maximum surface temperature reaches the condition of 54 ° C to 72 ° C, the above-mentioned unique holding effect can be obtained, and the above-mentioned conditions are used as an index indicating the unique holding effect. In addition, in order to satisfy the above conditions, it is important to study the manufacturing method of the heating appliance 1. In addition to the component (A) and component (B), research on the manufacturing method includes the amount of fragrance added thereto, the average particle size of the oxidized metal and the water-absorbing agent, the oxidized metal, the water-absorbing agent, water, etc. The content and the manufacturing method of the heat generating portion 10 are adjusted and combined as appropriate.

再者，於上述條件下，脫氣係藉由將溫熱器具1裝入隔氧性之袋之內部，自外側壓扁該袋將袋內部之空氣去除而進行，其後將其密閉以避免空氣進入。再者，此時可將溫熱器具1收容至外裝袋中，於收容之情形時，與外裝袋一併裝入該隔氧性之袋內部。處理係於50℃之一定之溫度下進行30天。其後，於溫度20℃、濕度60%環境下順化3天，自袋中取出溫熱器具1，將溫熱器具1於室溫20℃、濕度60%之大氣壓下於空氣中打開，藉此使發熱部10與空氣中之氧進行反應，利用氧化反應產生之發熱使發熱部10發熱。表面最高達到溫度係利用由該氧化反應引起之溫度上升獲得之溫度，為於發熱部10發熱期間所測定之溫度。Furthermore, under the above conditions, degassing is carried out by putting the warming device 1 inside the oxygen-proof bag, flattening the bag from the outside to remove the air inside the bag, and then sealing it to avoid Air enters. In addition, at this time, the heating appliance 1 can be accommodated in the outer bag, and in the case of storage, the inside of the oxygen-proof bag together with the outer bag. The treatment is carried out at a certain temperature of 50 ° C for 30 days. Afterwards, after 3 days of humidification in an environment with a temperature of 20 ° C and a humidity of 60%, the heating appliance 1 was taken out of the bag, and the heating appliance 1 was opened in the air at an atmospheric pressure of 20 ° C and a humidity of 60% at room temperature. This causes the heat generating portion 10 to react with oxygen in the air, and the heat generated by the oxidation reaction causes the heat generating portion 10 to generate heat. The highest surface temperature is the temperature obtained by the temperature rise caused by the oxidation reaction, and is the temperature measured during the heat generation period of the heat generating portion 10.

又，溫熱器具1若第2袋體片30b之外表面之最高達到溫度為54℃以上，則可對使用者賦予更有效之溫熱效果。In addition, if the maximum temperature of the outer surface of the second bag body sheet 30b of the heating device 1 reaches 54 ° C or more, a more effective heating effect can be imparted to the user.

以上，已參照圖1～3對溫熱器具1進行了說明，但其為本發明之例示，亦可採用溫熱器具1以外之各種構成。The warming device 1 has been described above with reference to FIGS. 1 to 3, but this is an example of the present invention, and various configurations other than the warming device 1 may be adopted.

That is, the heat generating part 121 contains at least an oxidizable metal, an absorbent, and water, and preferably further contains a reaction accelerator. The heat generating part 121 may be a single layer, a laminated structure, or a two-layer structure as shown in FIG. 1.

蒸汽溫熱器具100之賦香所使用之香料組合物與圖1之溫熱器具1可使用之香料組合物相同。藉此，可製成於使用時適當地產生蒸汽溫熱、並且可平衡性良好地表現出森林風格等之良好之芳香的蒸汽溫熱器具100。The fragrance composition used in the steam heating appliance 100 for aromatization is the same as the fragrance composition that can be used in the heating appliance 1 of FIG. 1. This makes it possible to produce a steam heating appliance 100 that appropriately generates steam temperature during use and can express a good aroma such as a forest style with good balance.

於蒸汽溫熱器具100中，袋體110具有位於靠近穿戴者之皮膚之側之第1袋體片110a、及位於遠離穿戴者之皮膚之側之第2袋體片110b。再者，第1袋體片110a對應於圖1之30a，第2袋體片110b對應於圖1之30b。In the steam heating appliance 100, the bag body 110 has a first bag body piece 110a located on the side close to the wearer's skin, and a second bag body piece 110b located on the side away from the wearer's skin. In addition, the 1st bag body piece 110a corresponds to 30a of FIG. 1, and the 2nd bag body piece 110b corresponds to 30b of FIG.

就提高使用時之溫感及使用感之觀點而言，關於基重，較佳為遠離皮膚之側之第2袋體片110b與靠近皮膚之側之第1袋體片110a相同或與其相比較小。第1袋體片110a及第2袋體片110b之厚度、構成纖維之粗細程度適當地選擇即可。From the viewpoint of improving the temperature and sense of use during use, regarding the basis weight, it is preferable that the second bag body sheet 110b on the side away from the skin is the same as or compared with the first bag body sheet 110a on the side near the skin small. The thickness of the first bag body piece 110a and the second bag body piece 110b and the thickness of the constituent fibers may be appropriately selected.

第1袋體片110a及第2袋體片110b形狀相同，為大致長圓形。並且，第1袋體片110a及第2袋體片110b之外形形成本體部101之外形。第1袋體片110a及第2袋體片110b藉由將該等重疊，將該等之周緣部接合，且將X方向之中央部沿Y方向接合(圖4之虛線部分)，而形成於內部具有2個空間之袋體110。為了將第1袋體片110a及第2袋體片110b接合，例如可使用熱熔接著劑。The first bag body piece 110a and the second bag body piece 110b have the same shape and are substantially oblong. Moreover, the outer shape of the first bag body piece 110a and the second bag body piece 110b forms the outer shape of the body portion 101. The first bag body piece 110a and the second bag body piece 110b are formed by overlapping these, joining the peripheral parts of the same, and joining the central part in the X direction in the Y direction (the dotted line part in FIG. 4). There are two pockets 110 inside. In order to join the first bag body piece 110a and the second bag body piece 110b, for example, a hot melt adhesive may be used.

於袋體110，於沿其X方向延伸之2條長邊之中央部之位置形成有沿Y方向自該長邊向內方切入而成之大致V字形之凹口部113a、113b。凹口部113a於佩戴蒸汽溫熱器具100時位於穿戴者之眉間或其附近。凹口部113b於佩戴蒸汽溫熱器具100時位於穿戴者之鼻樑。因此，與凹口部113a相比，凹口部113b之切入之程度較大。再者，圖5所示之凹口部113a、113b可為該等之至少一者為狹縫。At the center of the two long sides extending in the X direction of the bag body 110, there are formed substantially V-shaped notches 113a and 113b cut inward in the Y direction from the long sides. The notch portion 113a is located between or near the eyebrow of the wearer when the steam heating appliance 100 is worn. The notch portion 113b is located on the bridge of the nose of the wearer when the steam heating appliance 100 is worn. Therefore, the notch 113b is cut to a greater extent than the notch 113a. Furthermore, the notch portions 113a and 113b shown in FIG. 5 may be at least one of these slits.

圖6係圖示將發熱部121收容至至少一部分具有通氣性之收容體122內構成發熱體120而成者進而被收容至袋體110中之蒸汽溫熱器具100之例。於該例中，具體而言，收容體122具有將第1收容體片122a與第2收容體片122b之周緣部互相接合而形成之形狀。收容體122中相較於接合之周緣部，於內側之部分成為非接合狀態，由此形成收容發熱部121之單一之空間。收容體122對應於圖1之收容體20，具體而言，第1收容體片122a對應於圖1之第1收容體片20a，第2收容體片122b對應於第2收容體片20b。FIG. 6 illustrates an example of the steam heating device 100 in which the heat generating portion 121 is accommodated in at least a part of the air-permeable housing 122 to constitute the heat generating body 120 and then accommodated in the bag body 110. In this example, specifically, the storage body 122 has a shape formed by joining peripheral edges of the first storage body piece 122a and the second storage body piece 122b to each other. The inner portion of the housing 122 is in a non-joined state compared to the joined peripheral edge portion, thereby forming a single space for housing the heat generating portion 121. The storage body 122 corresponds to the storage body 20 of FIG. 1, specifically, the first storage body piece 122 a corresponds to the first storage body piece 20 a of FIG. 1, and the second storage body piece 122 b corresponds to the second storage body piece 20 b.

香料組合物較佳為施加至袋體110之內側至發熱部121之間，更佳為施加至袋體110之內側至收容體122之間，進而較佳為施加至收容體122之外側面，其中進而更佳為施加至第2收容體片122b之外側面。若於香料組合物與發熱部121之間介置第2收容體片122b，則香料組合物與發熱部121之距離變遠，因此可以物理方式抑制吸水劑對香味或發熱特性之影響。The fragrance composition is preferably applied from the inside of the bag body 110 to the heat generating portion 121, more preferably from the inside of the bag body 110 to the receiving body 122, and further preferably applied to the outer side of the receiving body 122. Among them, it is even more preferable to apply it to the outer surface of the second housing body piece 122b. When the second container sheet 122b is interposed between the fragrance composition and the heat generating portion 121, the distance between the fragrance composition and the heat generating portion 121 becomes longer, so that the influence of the water absorbing agent on the fragrance or the heat generating characteristics can be physically suppressed.

作為將香料組合物施加至袋體110之內側至發熱體120之間之其他具體例，例如可將對粉體或油脂之載體賦香所獲得之粉末香料或糊狀之賦香物製成片狀而施加於其間，亦可如圖6所示般於其間配置藉由香料組合物對片材料賦香而成之賦香片150而施加，亦可於袋體110之內側面直接塗佈香料組合物。As another specific example of applying the fragrance composition from the inside of the bag body 110 to the heating body 120, for example, a powdered fragrance or paste-like fragrance obtained by fragrance of a powder or grease carrier can be made into tablets It can also be applied between them, as shown in FIG. 6, and can also be arranged with a flavoring sheet 150 formed by flavoring the sheet material with a perfume composition, or a perfume combination can be directly coated on the inner side of the bag body 110 Thing.

作為將香料組合物施加至收容體122之外側面之具體例，可將香料組合物直接塗佈於收容體122之外側面之片材。再者，亦可將收容體122之外側面之片材製成與賦香片相同者，而對該片材施加香料組合物。即，可使用接著劑或熱熔等方法於第2收容體片122b之外側面積層與賦香片相同之片材，而將收容體122之外側面之片材製成與賦香片相同者。藉此，不會發生片材引起之溫度妨礙而可賦予充分之溫熱效果，並且賦香較容易，香料組合物之香味濃郁性變得極高，可更有效地表現出森林風格等之良好之芳香。賦香片150係與賦香片15相同之態樣。於使用賦香片150之情形時，具體而言，可藉由與袋體110之內側面鄰接地配置而實施，亦可藉由接著劑將賦香片150接著於袋體110之內側面而實施。As a specific example of applying the fragrance composition to the outer surface of the container 122, the fragrance composition may be directly applied to the sheet on the outer surface of the container 122. Furthermore, the sheet on the outer side of the container 122 may be made the same as the flavoring sheet, and a fragrance composition may be applied to the sheet. That is, a method such as an adhesive or hot-melt may be used on the outer side of the second container sheet 122b to have the same area layer as the flavoring sheet, and the sheet on the outer side of the container 122 may be made the same as the flavoring sheet. Thereby, sufficient temperature effect can be imparted without causing temperature interference caused by the sheet, and the fragrance can be easily given, the fragrance richness of the fragrance composition becomes extremely high, and the forest style etc. can be expressed more effectively. Of fragrance. The fragrance tablet 150 is the same as the fragrance tablet 15. When the fragrance-enhancing sheet 150 is used, specifically, it can be implemented by being disposed adjacent to the inner side of the bag body 110, or it can be implemented by adhering the fragrance-enhancing sheet 150 to the inner side of the bag body 110.

於使第1收容體片122a位於靠近穿戴者之皮膚之側並且使第2收容體片122b位於遠離穿戴者之皮膚之側之情形時，將賦香片150配置於位於遠離穿戴者之皮膚之側之第2收容體片122b側的外側面，或對外側面施加香料組合物，藉此可提高使用時之輕便性，並且對穿戴者之皮膚賦予充分之溫熱效果，同樣地達成良好之香味濃郁性。When the first storage body sheet 122a is located close to the wearer's skin and the second storage body sheet 122b is located away from the wearer's skin, the fragrance sheet 150 is placed on the side away from the wearer's skin The outer surface of the second container sheet 122b side, or applying a perfume composition to the outer surface, thereby improving portability during use, and imparting a sufficient warming effect to the skin of the wearer, likewise achieving good fragrance richness Sex.

作為第1收容體片122a及第2收容體片122b之具體之材料，可選擇與第1收容體片20a、第2收容體片20b相同者。又，第1收容體片122a及第2收容體片122b之通氣度可設定為與第1收容體片20a、第2收容體片20b相同。As specific materials of the first storage body piece 122a and the second storage body piece 122b, the same material as the first storage body piece 20a and the second storage body piece 20b can be selected. The air permeability of the first storage body piece 122a and the second storage body piece 122b can be set to be the same as that of the first storage body piece 20a and the second storage body piece 20b.
