The invention described in 3 is characterized in that the enclosing bag is made of an aluminum bag having a three-layer structure of polyethylene terephthalate (PET) on the outer surface, aluminum-deposited polyethylene terephthalate (VM-PET) on the middle, and polyethylene (PE) on the inner surface. and
又、請求項４記載の発明は、上記請求項１～３のいずれか１項に記載の救命採暖具及び非常食を包装袋体に収納してなることを特徴とする救命用具にある。 Further, the invention according to claim 4 is a lifesaving device characterized in that the lifesaving warming device and emergency food according to any one of claims 1 to 3 are contained in a packaging bag.
本発明は上述の如く、請求項１記載の発明にあっては、救命採暖具を救命胴衣、腰巻きタイプ、肩掛タイプの救命具に収納し、乗船、磯釣り時等の海難事故や水難事故に備えることになり、この際、例えば、装着者が不測の海難事故や水難事故に遭遇し、装着者が海中や水中に投げ出されたとき、救命胴衣、腰巻きタイプ、肩掛タイプの救命具に収納された上記救命採暖具は海水や淡水の水に接触し、通し穴状の丸穴又は四角穴状の通水口部から直ちに封入袋体内に海水や淡水の水が侵入し、海水や淡水の水は吸水シートに吸水され、水は吸水シートに包み込まれた発熱剤の内部に侵入し、発熱剤と水との接触により発熱反応が生じ、発熱反応により生じた熱は吸水シート及び封入袋体を介して遭難者に伝導され、吸水シートに吸水された水は発熱反応による熱によって蒸発して水蒸気が発生し、水蒸気は救命胴衣の内部空間に籠もり、水蒸気の対流により遭難者に熱が伝わり、しかして、発熱反応により生じた熱は封入袋体内の熱伝導を経た後、封入袋体からの熱伝達、水蒸気による対流及び熱放射により遭難者に伝わり、遭難者は熱伝達、対流及び熱放射により暖を採ることができ、救命採暖具により遭難者は身体の心臓部、手足部、頭部などを暖めることができ、さらに、発熱剤を包み込む吸水シートの高吸水性により発熱の維持時間及び効率的な発熱作用を長く得ることができ、吸水シートの存在により遭難者に対する熱傷も防ぐことができ、長時間にわたる漂流も可能となって海難事故や水難事故に対する有効な対策とすることができ、さらに、上記吸水シートは、高分子吸水材を含有する綿状のパルプ、パルプを挟んで包む吸水紙、及び吸水紙を包む不織布からなる吸水性の高いシート材で構成されているから、加水により膨張する高分子吸収材の採用により発熱開始時より適度な過度な発熱が抑えられ、適度な発熱温度の維持を図ることができる。 As described above, in the invention according to claim 1, the life-saving warming device is stored in a life jacket , a waist-wrapped type, or a shoulder-type life-saving device to prepare for sea accidents and water accidents during boarding, rock fishing, etc. In this case, for example, when the wearer encounters an unexpected marine accident or water accident and the wearer is thrown into the sea or water, the above-mentioned lifesaving equipment stored in a life jacket , waist wrap type, or shoulder type lifesaving device When the life-saving warmer comes into contact with seawater or freshwater, seawater or freshwater immediately enters the enclosing bag through the round hole or square hole-shaped water passage opening. The water is absorbed into the heat-generating agent wrapped in the water-absorbing sheet, and the heat-generating agent contacts the water, causing an exothermic reaction. The water absorbed by the water-absorbing sheet evaporates due to the heat generated by the exothermic reaction, and the water vapor stays in the inner space of the life jacket. After the heat generated by the exothermic reaction passes through the heat conduction inside the enclosing bag, it is transmitted to the victim by heat transfer from the enclosing bag, convection by water vapor and heat radiation, and the victim is warmed by heat transfer, convection and heat radiation. The life-saving warmers can warm the victim's heart, limbs, and head. The presence of the water-absorbent sheet prevents burn injuries to victims, and allows them to drift for long periods of time . , the water-absorbing sheet is composed of a highly water-absorbing sheet material composed of cotton-like pulp containing a polymer water-absorbing material, water-absorbing paper sandwiching the pulp and wrapping it, and non-woven fabric wrapping the water-absorbing paper, so that it expands with water. Excessive heat generation can be suppressed from the start of heat generation by adopting a high-molecular absorbing material, and a proper heat generation temperature can be maintained.
又、請求項２記載の発明にあっては、上記発熱剤は、透水性袋内に生石灰（酸化カルシウム）粉末及びアルミニウム粉末の混合粉末を充填してなるから、海水等の水と生石灰との反応、水と生石灰との反応によって生成される水酸化カルシウムとアルミニウムとの反応により発熱反応までの立ち上がり時間の短縮及び発熱量の増大、発熱温度、発熱時間の維持を図ることができ、発熱開始時より過度な発熱が抑えられ適度な発熱温度の維持を図ることができ、さらには、発熱剤の軽量化を図ることができ、使用の利便性を高めることができ、又、請求項３記載の発明にあっては、上記封入袋体は、外面がポリエチレンテレフタレート（ＰＥＴ）、中間にアルミニウム蒸着ポリエチレンテレフタレート（ＶＭ－ＰＥＴ）及び内面にポリエチレン（ＰＥ）の３層構造のアルミニウム袋から構成されているから、アルミニウム袋のアルミニウム蒸着ポリエチレンテレフタレートにより非透湿性（ガスバリアー性）、高遮光性及び高熱伝導率を得ることができ、発熱剤の生石灰の経年劣化を防いで使用の耐久性を向上することができ、緊急時に対応することができる。 In the second aspect of the present invention, the exothermic agent is formed by filling a mixed powder of quicklime (calcium oxide) powder and aluminum powder in the water-permeable bag. The reaction between calcium hydroxide and aluminum produced by the reaction of water and quicklime shortens the rise time up to the exothermic reaction, increases the amount of heat generated, maintains the heat generation temperature and heat generation time, and starts heat generation. It is possible to suppress excessive heat generation from time to time and maintain an appropriate heat generation temperature, and furthermore, it is possible to reduce the weight of the exothermic agent and improve the convenience of use. In the above invention, the enclosing bag is composed of an aluminum bag having a three-layer structure of polyethylene terephthalate (PET) on the outer surface, aluminized polyethylene terephthalate (VM-PET) in the middle, and polyethylene (PE) on the inner surface. Therefore, the aluminum vapor-deposited polyethylene terephthalate of the aluminum bag can provide impermeability (gas barrier property), high light shielding property and high thermal conductivity, and it can prevent the deterioration of the quicklime of the exothermic agent over time and improve the durability of use. and can respond to emergencies.
又、請求項４記載の発明にあっては、救命採暖具を救命胴衣、腰巻きタイプ、肩掛タイプの救命具に収納し、乗船、磯釣り時等の海難事故や水難事故に備えることになり、この際、例えば、装着者が不測の海難事故や水難事故に遭遇し、装着者が海中や水中に投げ出されたとき、包装袋体を開封すると、救命胴衣、腰巻きタイプ、肩掛タイプの救命具に収納された上記救命採暖具は海水や淡水の水に接触し、通し穴状の丸穴又は四角穴状の通水口部から直ちに封入袋体内に海水や淡水の水が侵入し、海水や淡水の水は吸水シートに吸水され、水は吸水シートに包み込まれた発熱剤の内部に侵入し、発熱剤と水との接触により発熱反応が生じ、発熱反応により生じた熱は吸水シート及び封入袋体を介して遭難者に伝導され、吸水シートに吸水された水は発熱反応による熱によって蒸発して水蒸気が発生し、水蒸気は救命胴衣の内部空間に籠もり、水蒸気の対流により遭難者に熱が伝わり、しかして、発熱反応により生じた熱は封入袋体内の熱伝導を経た後、封入袋体からの熱伝達、水蒸気による対流及び熱放射により遭難者に伝わり、遭難者は熱伝達、対流及び熱放射により暖を採ることができ、救命採暖具により遭難者は身体の心臓部、手足部、頭部などを暖めることができ、さらに、発熱剤を包み込む吸水シートの高吸水性により発熱の維持時間及び効率的な発熱作用を長く得ることができ、吸水シートの存在により遭難者に対する熱傷も防ぐことができ、長時間にわたる漂流も可能となって海難事故や水難事故に対する有効な対策とすることができ、さらに、上記吸水シートは、高分子吸水材を含有する綿状のパルプ、パルプを挟んで包む吸水紙、及び吸水紙を包む不織布からなる吸水性の高いシート材で構成されているから、加水により膨張する高分子吸収材の採用により発熱開始時より適度な過度な発熱が抑えられ、適度な発熱温度の維持を図ることができ、さらに、上記包装袋体に上記救命採暖具と一緒に非常食を収納してなるから、包装袋体内に収納した非常食の存在により、一層、長時間にわたる漂流に備えることができ、海難事故や水難事故に対する有効な対策とすることができる。 In addition, in the invention of claim 4 , the lifesaving warmer is stored in a life jacket , a loincloth type, or a shoulder type lifesaving device to prepare for a sea accident or a water accident when boarding a ship or surf fishing. When, for example, the wearer encounters an unexpected maritime accident or water accident and is thrown into the sea or water, when the packaging bag is opened, it can be stored in a life jacket , waist wrap type, or shoulder type life preserver. The above-mentioned lifesaving warming device comes into contact with seawater or freshwater, and seawater or freshwater immediately enters the sealed bag from the round hole or square hole-shaped water passage opening. Water is absorbed by the water-absorbing sheet, and the water enters the inside of the exothermic agent wrapped in the water-absorbing sheet, and the contact between the exothermic agent and the water causes an exothermic reaction, and the heat generated by the exothermic reaction passes through the water-absorbing sheet and the enclosing bag. The water absorbed by the water-absorbing sheet evaporates due to the heat generated by the exothermic reaction, generating steam. Thus, the heat generated by the exothermic reaction passes through the heat conduction in the enclosing bag, and then is transmitted to the victim by heat transfer from the enclosing bag, convection by water vapor, and heat radiation. The life-saving warmers can warm the victim's heart, limbs, and head. Efficient heat generation can be obtained for a long time, and the presence of the water-absorbing sheet can prevent burn injuries to victims, and can be drifted for a long time, making it an effective measure against accidents at sea and water accidents. Furthermore, the water-absorbing sheet is composed of a highly water-absorbing sheet material composed of cotton-like pulp containing a high-molecular water-absorbing material, water-absorbing paper sandwiching and wrapping the pulp, and non-woven fabric wrapping the water-absorbing paper. Excessive heat generation can be suppressed from the start of heat generation by adopting a polymer absorbent material that expands due to heat, and it is possible to maintain a moderate heat generation temperature. Since food is stored, the presence of emergency food stored in the packaging bag makes it possible to prepare for drifting for a long time, which is an effective measure against marine accidents and water accidents .

この実施の第一形態例は上記構成であるから、図１、図２の如く、上記吸水シートＳの三本の仮想折線Ｓ６により形成される６区画のうちの１区画に上記発熱剤Ｈを載置し、図４（ａ）、（ｂ）、（ｃ）の手順で三本の仮想折線Ｓ６の位置で吸水シートＳを折り畳み、同図（ｃ）の如く、吸水シートＳにより発熱剤Ｈを包み込み、図４の如く、折り畳み状態において、発熱剤Ｈを吸水シートＳの中央位置に包み込み、図１、図３の如く、発熱剤Ｈを包み込んだ吸水シートＳを封入袋体Ｆ内に封入し、開口部Ｆ３をヒートシール部Ｆ２で熱圧着固定し、救命採暖具Ｒを製作することになる。 Since this first embodiment has the above configuration, one of the six sections formed by the three imaginary folding lines S6 of the water absorbent sheet S is provided with the exothermic agent H as shown in FIGS. 4(a), (b), and (c), the water absorbent sheet S is folded at the positions of the three virtual folding lines S6 , and as shown in FIG. 4(c), the water absorbent sheet S generates heat. 4, the exothermic agent H is wrapped in the central position of the water absorbent sheet S in the folded state, and the water absorbent sheet S including the exothermic agent H is placed in the enclosing bag F as shown in FIGS. , and the opening F3 is thermocompression-fixed with the heat-sealed part F2 to manufacture the life-saving warming device R.
そして、図７の如く、この救命採暖具Ｒを救命胴衣Ｗ等の救命具に収納し、例えば、装着者の心臓の近傍に対向する位置に形成されたポケット内に救命採暖具Ｒを配置して乗船、磯釣り時等の海難事故等に備えることになる。 Then, as shown in FIG. 7, this lifesaving warming device R is housed in a lifesaving device such as a life jacket W, and for example, the lifesaving warming device R is placed in a pocket formed in a position facing the vicinity of the wearer's heart. It will prepare for marine accidents, etc., when boarding a ship or when fishing from a rock.
この際、例えば、装着者が不測の海難事故や水難事故に遭遇し、装着者が海中や水中に投げ出されたとき、救命胴衣Ｗ等の救命具に収納された上記救命採暖具Ｒは海水や淡水の水に接触し、通水口部Ｔから直ちに封入袋体Ｆ内に海水等の水が侵入し、海水等の水は吸水シートＳに吸水され、水は吸水シートＳに包み込まれた発熱剤Ｈの透水性袋Ｈ１を通過して発熱剤Ｈの内部に侵入し、発熱剤Ｈと水との接触により発熱反応が生じ、発熱反応により生じた熱は吸水シートＳ及び封入袋体Ｆを介して遭難者に伝導され、吸水シートＳに吸水された水は発熱反応による熱によって蒸発して水蒸気が発生し、水蒸気は救命胴衣Ｗの内部空間に籠もり、水蒸気の対流により遭難者に熱が伝わり、しかして、発熱反応により生じた熱は封入袋体Ｆ内の熱伝導を経た後、封入袋体Ｆからの熱伝達、水蒸気による対流及び熱放射により遭難者に伝わり、遭難者は熱伝達、対流及び熱放射により暖を採ることができ、救命採暖具Ｒにより遭難者は身体の心臓部、手足部、頭部などを暖めることができ、さらに、発熱剤Ｈを包み込む吸水シートＳの高吸水性により発熱の維持時間及び効率的な発熱作用を長く得ることができ、吸水シートＳの存在により遭難者に対する熱傷も防ぐことができ、長時間にわたる漂流も可能となって海難事故等に対する有効な対策とすることができる。 At this time, for example, when the wearer encounters an unexpected marine accident or water accident and the wearer is thrown into the sea or water, the life-saving warming device R stored in a life-saving device such as a life jacket W may be exposed to seawater or freshwater. When the exothermic agent H comes into contact with the water, the water such as seawater immediately enters the enclosed bag body F from the water passage portion T, the water such as seawater is absorbed by the water absorbent sheet S, and the water is wrapped in the water absorbent sheet S. The water permeable bag H 1 penetrates into the exothermic agent H, and an exothermic reaction occurs due to the contact between the exothermic agent H and water. The water absorbed by the water-absorbing sheet S evaporates due to the heat generated by the exothermic reaction, generating steam. After the heat generated by the exothermic reaction passes through the heat conduction inside the enclosing bag F, it is transmitted to the victim by heat transfer from the enclosing bag F, convection by steam, and heat radiation, and the victim receives heat transfer. , convection and heat radiation, and the life-saving equipment R can warm the heart, limbs, and head of the victim. Due to water absorption, heat generation can be maintained for a long time and efficient heat generation action can be obtained, and the presence of the water-absorbing sheet S can prevent burns to victims, and it is possible to drift for a long time, which is effective against marine accidents. can be taken as a countermeasure.

Excessive heat generation can be suppressed from time to time, and an appropriate heat generation temperature can be maintained. Furthermore, the weight of the exothermic agent H can be reduced, and the convenience of use can be improved.
又、この場合、図６の如く、上記吸水シートＳは、高分子吸水材Ｓ１（高吸水性高分子・高吸水性ポリマー）を含有する綿状のパルプＳ２、パルプＳ２を包む吸水紙Ｓ３・Ｓ３、この場合、二枚の吸水紙Ｓ３・Ｓ２で挟んでパルプＳ２を包み、及び、吸水紙Ｓ３・Ｓ３を包む不織布Ｓ４・Ｓ４からなるホットメルト接着剤Ｓ７による３層構造の吸水性の高いシート材で構成されているから、発熱剤Ｈを包み込む吸水シートＳの高吸水性により発熱の維持時間及び効率的な発熱作用を長く得ることができ、加水により膨張する高分子吸収材Ｓ１の採用により発熱開始時より適度な過度な発熱が抑えられ、適度な発熱温度の維持を図ることができ、吸水シートＳの存在により遭難者に対する熱傷も防ぐことができ、長時間にわたる漂流も可能となって海難事故等に対する有効な対策とすることができる。 In this case, as shown in FIG. 6, the water-absorbing sheet S includes a cotton-like pulp S 2 containing a high-molecular water-absorbing material S 1 (superabsorbent polymer/high-absorbent polymer), and a water-absorbent material surrounding the pulp S 2 . Paper S 3 /S 3 , in this case, sandwiched between two water absorbent papers S 3 /S 2 to wrap the pulp S 2 , and a hot melt consisting of a nonwoven fabric S 4 /S 4 wrapping the water absorbent papers S 3 /S 3 Since the sheet material has a three-layer structure with the adhesive S7 and is highly water-absorbing, the high water-absorbing property of the water-absorbing sheet S enveloping the exothermic agent H makes it possible to maintain the heat generation for a long time and to obtain an efficient heat-generating action. Excessive heat generation can be suppressed from the start of heat generation by adopting the polymer absorbent material S1 that expands with water, and a moderate heat generation temperature can be maintained. It is also possible to prevent drifting for a long time, which is an effective measure against accidents at sea.
又、この場合、図１、図２の如く、上記封入袋体Ｆは、外面がポリエチレンテレフタレート（ＰＥＴ）、中間にアルミニウム蒸着ポリエチレンテレフタレート（ＶＭ－ＰＥＴ）及び内面にポリエチレン（ＰＥ）の３層構造のアルミニウム袋Ｆ１から構成されているから、アルミニウム袋Ｆ１のアルミニウム蒸着ポリエチレンテレフタレートにより非透湿性（ガスバリアー性）、高遮光性及び高熱伝導率を得ることができ、発熱剤Ｈの生石灰の経年劣化を防いで使用の耐久性を向上することができ、緊急時に対応することができる。 In this case, as shown in FIGS. 1 and 2, the enclosing bag F has a three-layer structure of polyethylene terephthalate (PET) on the outer surface, aluminum-deposited polyethylene terephthalate (VM-PET) on the middle, and polyethylene (PE) on the inner surface.
