Description

本考案は、加水発熱剤用外装容器に関する。より詳細には、加水発熱剤を収容し、且つ反応水を注水するための注水容器と兼用となる容器であって、注水量を正確に表示する手段を設けた加水発熱剤用外装容器に関する。 The present invention relates to an outer container for a hydrothermal exothermic agent. More specifically, the present invention relates to an outer container for a hydrothermal agent, which is a container that contains a hydrothermal agent and also serves as a water injection container for injecting reaction water, and is provided with means for accurately displaying the amount of water to be injected.

従来から、水と反応させて発生する熱を利用する、いわゆる「加水発熱剤」が各種利用されている。 Conventionally, various so-called “hydrothermal agents” that utilize heat generated by reaction with water have been used.

加水発熱剤の代表的なものは、粉体酸化カルシウム(CaO)と水との発熱反応を利用したもの、或いは粉体酸化カルシウム(CaO)と粉体アルミニウム(Al)との混合物と水との発熱反応を利用したものがある（例えば、特許文献１参照）。 Typical examples of the hydrothermal exothermic agent are those using an exothermic reaction between powdered calcium oxide (CaO) and water, or a mixture of powdered calcium oxide (CaO) and powdered aluminum (Al) and water. Some use an exothermic reaction (see, for example, Patent Document 1).

粉体酸化カルシウム(CaO)と水との発熱反応を利用したもの、粉体酸化カルシウム(CaO)と粉体アルミニウム(Al)との混合物と水との発熱反応を利用した発熱剤は、いずれも下記の反応を利用したものである。
ＣａＯ＋Ｈ_２Ｏ＝Ｃａ（ＯＨ）_２＋１．５６Ｋｃａｌ
この反応は発熱反応である。発熱が激しいときは、３００〜４５０℃にも達することがある。従って、反応中、化合すべき水の一部が水蒸気となって失われるので、理論量以上の多量の水を必要とする。水が少なすぎると、発生する水蒸気の量が少なく、所要の熱量を得ることができなくなる。即ち、添加すべき水の量を予め正確に計量することが必要である。 Any exothermic agent that utilizes an exothermic reaction between powdered calcium oxide (CaO) and water, and an exothermic agent that utilizes an exothermic reaction between a mixture of powdered calcium oxide (CaO) and powdered aluminum (Al) and water, The following reaction is used.
CaO + H ₂ O = Ca (OH) ₂ +1.56 Kcal
This reaction is an exothermic reaction. When the exotherm is intense, it may reach 300 to 450 ° C. Therefore, during the reaction, a part of the water to be combined is lost as water vapor, so that a larger amount of water than the theoretical amount is required. If the amount of water is too small, the amount of water vapor generated is small and the required amount of heat cannot be obtained. That is, it is necessary to accurately measure the amount of water to be added in advance.

ところで、粉体酸化カルシウム(CaO)、或いは粉体酸化カルシウム(CaO)と粉体アルミニウム(Al)との混合物と水との発熱反応を利用した加水発熱剤を製造する工程では、通常、先ず、粉体酸化カルシウム(CaO)、或いは粉体酸化カルシウム(CaO)と粉体アルミニウム(Al)との混合物を透水性の不織布、和紙、合成紙等の袋に充填した後、さらに粉体酸化カルシウムが空気中の水分を吸収して失活するのを防止するために、アルミ箔等非透水性の外装容器に包装している。 By the way, in the process of producing a hydrothermal exothermic agent using an exothermic reaction between powdered calcium oxide (CaO) or a mixture of powdered calcium oxide (CaO) and powdered aluminum (Al) and water, usually, first, Powder calcium oxide (CaO) or a mixture of powdered calcium oxide (CaO) and powder aluminum (Al) is filled into a bag of water-permeable nonwoven fabric, Japanese paper, synthetic paper, etc. In order to prevent inactivation by absorbing moisture in the air, it is packaged in a water-impermeable exterior container such as aluminum foil.

加水発熱剤の利点の一つは携帯することができ、使用者が時、場所を選ばずに使用することができることである。 One of the advantages of the hydrothermal exothermic agent is that it can be carried and used by the user from time to place.

そのために、水を計量するために余計な容器、道具等を使用、或いは携行しないでもいいように、アルミ箔等非透水性の外装容器自体を水の計量容器として使用するようになっている。即ち、アルミ箔等非透水性の外装容器を所定の箇所で開裂して、不織布等の内装容器に充填した発熱剤を取り出し、加熱したい食材等を入れた食器等容器の底部に置き、アルミ箔等非透水性の外装容器に所定量の反応水を入れて、前記食器等容器の底部に注水していた。 Therefore, a non-water-permeable outer container such as aluminum foil itself is used as a water measuring container so that an extra container, tool or the like for measuring water may not be used or carried. That is, a non-permeable outer container such as an aluminum foil is cleaved at a predetermined location, a heating agent filled in the inner container such as a nonwoven fabric is taken out, and placed on the bottom of a container such as a tableware containing ingredients to be heated. A predetermined amount of reaction water was put into an equal water-impervious outer container and poured into the bottom of the tableware container.

ところで、液体等水を計量するための容器として、従来から、透明なガラス、アクリル等合成樹脂で製造された硬質製カップ、あるいは軟質合成樹脂製の袋がある。これらは透明であるために、計量線が表面に印刷されていて、目視により正確に計量できるようになっている。一方、加水発熱剤は、紫外線劣化、吸湿・吸水等を防止するために不透明性の材料であるアルミ箔の外装容器に収容しなければならない。そのために、外装容器の外表面に計量線を印刷したとしても、目視により正確に計量することは不可能である。 By the way, as a container for measuring water such as liquid, there are conventionally a hard cup made of a synthetic resin such as transparent glass and acrylic, or a bag made of a soft synthetic resin. Since these are transparent, a measurement line is printed on the surface so that the measurement can be accurately performed visually. On the other hand, the hydrothermal exothermic agent must be accommodated in an aluminum foil outer container, which is an opaque material, in order to prevent UV degradation, moisture absorption and water absorption. Therefore, even if a measurement line is printed on the outer surface of the outer container, it is impossible to accurately measure it visually.

従って、従来、水を正確に計量するための計量線はアルミ箔等非透水性の外装容器の内表面に印刷していた。 Therefore, conventionally, a measuring line for accurately measuring water has been printed on the inner surface of a non-permeable outer container such as aluminum foil.

図５は、従来の外装容器１の正面図である。図６は、同じく製袋する前の展開図である。図７は、開裂した外装容器１を６０度上方から覗いた斜視図である。 FIG. 5 is a front view of a conventional exterior container 1. FIG. 6 is a development view before bag making. FIG. 7 is a perspective view of the cut outer container 1 as viewed from above 60 degrees.

図５に示すように、従来の外装容器２０には開裂するためのＶ型ノッチ５のみが形成されている。図６に示すように、外装容器２０の内表面２２に水計量ライン２４があらかじめ印刷してある。製袋する場合は、中央線Ｌを谷側に折り曲げてから、熱融着部２及び４をそれぞれ熱融着して、発熱剤を充填した不織布製内装袋３０を入れて、熱融着部３を熱融着して密封するようになっている。 As shown in FIG. 5, only the V-shaped notch 5 for cleaving is formed in the conventional exterior container 20. As shown in FIG. 6, a water metering line 24 is printed in advance on the inner surface 22 of the outer container 20. In the case of making a bag, the center line L is bent to the valley side, the heat fusion parts 2 and 4 are thermally fused, and the non-woven interior bag 30 filled with a heat generating agent is put, and the heat fusion part 3 is heat-sealed and sealed.

図５、図６および図７に示した従来技術の欠点は、Ｖ型ノッチ５の所からアルミ箔製外装容器２０を開裂して、発熱剤を充填した不織布製内装袋３０を取り出した後、外装容器２０の残骸を計量カップ２６として再利用する際、水計量線２４を上から覗いて（図７参照）、水を注水しようとしても、計量線２４が深い所にあるので、その位置を正確に確認出来ないことである。さらに、計量線２４の近傍まで水を注水すると光の屈折により計量線２４が浮き上がって見えるので、満水状態と錯視され、計量線２４通りに正確な量の水を注水することは不可能であった。
特許第３４６７７２９号明細書 The disadvantages of the prior art shown in FIGS. 5, 6 and 7 are that after the aluminum foil outer container 20 is cleaved from the V-shaped notch 5 and the non-woven inner bag 30 filled with a heat generating agent is taken out, When reusing the wreckage of the outer container 20 as the measuring cup 26, looking into the water measuring line 24 from above (see FIG. 7) and trying to inject water, the measuring line 24 is in a deep place. It cannot be confirmed accurately. Further, when water is poured to the vicinity of the measuring line 24, the measuring line 24 appears to float due to light refraction, so that it is illusion that the water is full and it is impossible to inject an accurate amount of water along the measuring line 24. It was.

考案が解決しようとする課題は、内装容器に充填された加水発熱剤を収容し且つ反応水を注水するための注水容器と兼用となる加水発熱剤用外装容器で、注水量を正確に計量できるようにすることである。 The problem to be solved by the invention is an outer container for the hydropyrogen that contains the hydrothermal agent filled in the interior container and also serves as a water injection container for injecting the reaction water. Is to do so.

本考案者は、アルミ箔等の外装容器の内表面に計量線を印刷する従来技術では、計量線を上から覗いた場合、正確に確認出来ないこと、および計量線の近傍まで水を注水すると光の屈折により計量線が浮き上がって見えるという欠点に鑑みて、注水した水面を水平の位置から直接目視で確認できるように検討した。 The inventor of the prior art that prints a measuring line on the inner surface of an outer container such as an aluminum foil cannot accurately check if the measuring line is viewed from above, and if water is poured to the vicinity of the measuring line. In view of the drawback that the measuring line appears to rise due to the refraction of light, the water surface that was poured was examined so that it could be directly visually confirmed from a horizontal position.

本考案によると、上記課題は、次のようにして解決される。 According to the present invention, the above problem is solved as follows.

１．透水性の内装容器に充填された加水発熱剤を収容し且つ反応水を注水するための注水容器と兼用となる加水発熱剤用外装容器であって、
加水発熱剤用外装容器の長手方向の熱融着部の所定の箇所に加水発熱剤用外装容器を開裂するための外装容器開裂用Ｖ型ノッチと、外装容器開裂用Ｖ型ノッチの下方部において、予め発熱剤との発熱反応に必要な量の水を収容する容積を形成する位置に形成した折り曲げ線を設けた加水発熱剤用外装容器。 1.

２．前記折り曲げ線６を、反応水の必要量に応じて複数本設けた前記１に記載した加水発熱剤用外装容器。 2. The outer container for a hydrothermal exothermic agent as described in 1 above, wherein a plurality of the folding lines 6 are provided according to the required amount of reaction water.

３．透水性の内装容器に充填された加水発熱剤を収容し且つ反応水を注水するための注水容器と兼用となる加水発熱剤用外装容器１Ａであって、
加水発熱剤用外装容器１Ａの長手方向の熱融着部２の所定の箇所に加水発熱剤用外装容器１Ａを開裂するための外装容器開裂用Ｖ型ノッチ５と、外装容器開裂用Ｖ型ノッチ５の下方部において反応水計量線を形成するための反応水計量線形成用Ｖ型ノッチ９を設けた加水発熱剤用外装容器。 3. A hydrothermal exothermic agent outer container 1A that contains a hydrothermal exothermic agent filled in a water-permeable interior container and serves also as a water injection container for injecting reaction water,
The outer container tearing V-shaped notch 5 for cleaving the outer heating container for hydrothermal heating agent 1A at a predetermined location of the heat fusion part 2 in the longitudinal direction of the outer casing for hydrothermal heating agent 1A, and the V-shaped notch for tearing the outer packaging An outer container for a hydrothermal exothermic agent provided with a V-shaped notch 9 for forming a reaction water measurement line for forming a reaction water measurement line at the lower part of 5.

４．前記反応水計量線形成用Ｖ型ノッチ９を、反応水の必要量に応じて複数個設けた前記３に記載した加水発熱剤用外装容器。 4). The outer container for a hydrothermal exothermic agent as described in 3 above, wherein a plurality of the V-shaped notches 9 for forming the reaction water measuring line are provided according to the required amount of reaction water.

前記１に記載した考案によれば、アルミ箔等の外装容器の内表面に水の計量線を印刷した従来技術と異なり、アルミ箔等の外装容器を、外装容器開裂用Ｖ型ノッチの下方部において、予め発熱剤との発熱反応に必要な量の水を収容する容積を形成する位置に形成した折り曲げ線に沿って折り曲げると、外装容器の上方部自体が、予め計算した所定量の反応水しか入らない計量カップとなるので、反応水の計量の誤差が殆どゼロになる。 According to the device described in 1 above, unlike the prior art in which a water metering line is printed on the inner surface of an outer container such as an aluminum foil, the outer container such as an aluminum foil is placed below the V-shaped notch for tearing the outer container. In this case, the upper part of the outer container itself is subjected to a predetermined amount of reaction water calculated in advance when folded along a fold line formed in a position that forms a volume for storing an amount of water necessary for the exothermic reaction with the exothermic agent in advance. Since the measuring cup can only enter, the error in measuring the reaction water becomes almost zero.

前記２に記載した考案によれば、折り曲げ線６を、反応水の必要量に応じて複数本設けることにより、反応水の必要量毎に外装容器を製造する必要が無くなり、コストの低減化につながる。 According to the device described in 2 above, by providing a plurality of folding lines 6 according to the required amount of reaction water, it is not necessary to manufacture an outer container for each required amount of reaction water, thereby reducing costs. Connected.

前記３に記載した考案によれば、アルミ箔等の外装容器の内表面に水の計量線を印刷した従来技術と異なり、アルミ箔等の外装容器を反応水計量線形成用Ｖ型ノッチから開裂すると、そのカットライン自体が反応水の計量線となり、所定量の反応水しか入らない計量カップとなるので、反応水の計量の誤差が殆どゼロになる。 According to the device described in 3 above, unlike the conventional technique in which a water metering line is printed on the inner surface of an outer container such as an aluminum foil, the outer container such as an aluminum foil is cleaved from the V-shaped notch for forming a reaction water metering line. Then, the cut line itself becomes a measuring line for the reaction water, and becomes a measuring cup that contains only a predetermined amount of the reaction water, so that the error in measuring the reaction water becomes almost zero.

前記４に記載した考案によれば、反応水計量線形成用Ｖ型ノッチを、反応水の必要量に応じて複数個設けることにより、反応水の必要量毎に外装容器を製造する必要が無くなり、コストの低減化につながる。 According to the device described in 4 above, by providing a plurality of V-shaped notches for forming a reaction water measuring line according to the required amount of reaction water, it is not necessary to manufacture an outer container for each required amount of reaction water. , Leading to cost reduction.

本考案者は、外装容器の内表面に反応水の計量線を印刷し、注水した後、上から覗く従来技術では、水和反応を過不足なく行わせるのに必要な水の量を正確に計量できないことに鑑みて、メニスカスを水平の位置から確認できるように改良して本考案を完成した。 The inventor has printed the measurement line of the reaction water on the inner surface of the outer container, poured water, and in the conventional technology peeking from above, the amount of water required for the hydration reaction to be performed without excess or deficiency is accurately determined. In view of the inability to weigh, the present invention has been completed by improving the meniscus so that it can be confirmed from a horizontal position.

図１は、本考案の１実施例を示す正面図である。図２は計量カップとしての使用手順を示す見取図である。本考案の外装容器１には、発熱剤を充填した不織布製内装袋（図示せず）を入れて、熱融着部２、３、４を熱融着して密封するようになっている。 FIG. 1 is a front view showing an embodiment of the present invention. FIG. 2 is a sketch showing the procedure for use as a measuring cup. A non-woven fabric interior bag (not shown) filled with a heat generating agent is placed in the outer container 1 of the present invention, and the heat-sealing portions 2, 3, and 4 are heat-sealed and sealed.

５は、外装容器１を開裂するために熱融着部２に形成されたＶ型ノッチである。６は、外装容器開裂用Ｖ型ノッチ５の下方部に形成された折り曲げ線である。 Reference numeral 5 denotes a V-shaped notch formed in the heat-sealing portion 2 in order to cleave the outer container 1. Reference numeral 6 denotes a fold line formed in the lower part of the V-shaped notch 5 for cleaving the outer container.

折り曲げ線６を形成する手順を説明する。先ず、発熱剤の質量毎に、発熱反応に必要な量の水を予め計算する。図２aに示すように、折り曲げ線６から折り曲げて、計量カップ７（図２ｂ）を形成したときの容積が、丁度発熱反応に必要な量の水を収容するような位置に形成する。注水する水の必要量に応じて、複数本の折り曲げ線６を設けることができる。例えば、外装容器１内に収納される発熱剤充填不織布製内装袋の容量に応じて複数本の折り曲げ線６を使い分けることができる。従って、例えば、外装容器１内に収納される発熱剤充填不織布製内装袋の容量が５ｇの場合、１２０ｍｌの注水量に対応するする折り曲げ線６で折り曲げ、外装容器１内に収納される発熱剤充填不織布製内装袋の容量が１０ｇの場合、１８０ｍｌの注水量に対応するする折り曲げ線６’で折り曲げるようにすることができる。この場合、各折り曲げ線に注水量を表示することもできる。 A procedure for forming the folding line 6 will be described. First, the amount of water required for the exothermic reaction is calculated in advance for each mass of the exothermic agent. As shown in FIG. 2a, the volume when the measuring cup 7 (FIG. 2b) is formed by being folded from the fold line 6 is formed at a position that just accommodates the amount of water required for the exothermic reaction. A plurality of folding lines 6 can be provided according to the required amount of water to be poured. For example, according to the capacity | capacitance of the heat generating agent filling nonwoven fabric interior bag accommodated in the exterior container 1, the multiple folding line 6 can be used properly. Therefore, for example, when the capacity of the heat-filler-filled nonwoven fabric-made interior bag accommodated in the outer container 1 is 5 g, the heat-generating agent is folded at the fold line 6 corresponding to the amount of water injection of 120 ml and stored in the outer container 1. When the capacity of the filled non-woven fabric inner bag is 10 g, it can be folded at a fold line 6 ′ corresponding to a water injection amount of 180 ml. In this case, the water injection amount can be displayed on each fold line.

折り曲げ線６を折り曲げて計量カップとして使用する手順を説明する。外装容器１の開裂ノッチ５から開裂して、内装容器に充填されている発熱剤（図示せず）を取り出して、所定の食品加熱用容器（図示せず）の底部に置く。空になった外装容器１を、折り曲げ線６に沿って確実に折り曲げ（図２a参照)、手で把持して計量カップ７を形成し、開口部８を完全に開き、切口すり切れに注水する（図２ｂ参照）。さらに、正確な秤量が必要な場合は、切口を目と同じ位置にしてメニスカスを目視で確認する。 A procedure for folding the fold line 6 and using it as a measuring cup will be described. The external container 1 is cleaved from the cleavage notch 5 and the heat generating agent (not shown) filled in the internal container is taken out and placed on the bottom of a predetermined food heating container (not shown). The empty outer container 1 is securely bent along the fold line 6 (see FIG. 2a), grasped by hand to form the measuring cup 7, completely opening the opening 8 and pouring water into the cut edge. (See FIG. 2b). Furthermore, when an accurate weighing is required, the meniscus is visually confirmed with the cut at the same position as the eye.

外装容器１の開裂用Ｖ型ノッチ５の下方部において、形成された折り曲げ線６に沿って折り曲げると、外装容器の上方部自体の容積は、発熱剤の質量に応じた所定量の水しか入らないように予め計算してあるので、水の計量の誤差が殆どゼロになる。さらに、メニスカスをも水平位置から直接目視で確認できる。 When the lower part of the V-shaped notch 5 for cleavage of the outer container 1 is bent along the formed folding line 6, the volume of the upper part of the outer container itself contains only a predetermined amount of water according to the mass of the heat generating agent. Since it has been calculated in advance so that there is no error, the error in measuring water becomes almost zero. Furthermore, the meniscus can also be visually confirmed directly from the horizontal position.

図３は、本考案の別の実施例を示す正面図である。図４は水計量カップとしての使用手順を示す見取図である。本考案の外装容器１Ａには、発熱剤を充填した不織布製内装袋（図示せず）を入れて、熱融着部２、３、４を熱融着して密封するようになっている。 FIG. 3 is a front view showing another embodiment of the present invention. FIG. 4 is a sketch showing the procedure for use as a water measuring cup. In the exterior container 1A of the present invention, a non-woven fabric interior bag (not shown) filled with a heat generating agent is put, and the heat-sealed portions 2, 3, and 4 are heat-sealed and sealed.

５は、外装容器１Ａを開裂するために熱融着部２に形成されたＶ型ノッチである。９は、反応水の所定量毎に形成された水計量用のＶ型ノッチである。 Reference numeral 5 denotes a V-shaped notch formed in the heat-sealing portion 2 in order to cleave the outer container 1A. 9 is a V-shaped notch for water measurement formed for each predetermined amount of reaction water.

図４（a)に示したように、先ず、外装容器１Ａの開裂ノッチ５から開裂して、収容されている透水性の容器に充填された発熱剤（図示せず）を取り出して、所定の食品加熱用容器（図示せず）の底部に置く。次に、空になった外装容器１Ａに形成された反応水計量線形成用Ｖ型ノッチ９を開裂し、計量カップ７Ａを形成する。次いで、図２（ｂ）に示したように、計量カップ７Ａの下方部分を把持して、開口の縁部のすり切れまで注水する。 As shown in FIG. 4 (a), first, a heating agent (not shown) which is cleaved from the cleaving notch 5 of the outer container 1A and filled in the water-permeable container accommodated is taken out, Place on the bottom of a food heating container (not shown). Next, the reaction water measuring line forming V-shaped notch 9 formed in the empty outer container 1A is cleaved to form a measuring cup 7A. Next, as shown in FIG. 2 (b), the lower part of the measuring cup 7A is gripped, and water is poured to the edge of the opening.

外装容器１Ａに形成された反応水計量線形成用Ｖ型ノッチ９を開裂した残部（すなわち、計量カップ７Ａ）の容積は、発熱剤の質量に応じた所定量の水しか入らないように予め計算してあるので、水の計量の誤差が殆どゼロになる。さらに、メニスカスをも水平位置から直接目視で確認できる。 The volume of the remaining portion (that is, the measuring cup 7A) obtained by cleaving the V-shaped notch 9 for forming the reaction water measuring line formed in the outer container 1A is calculated in advance so that only a predetermined amount of water according to the mass of the exothermic agent can enter. As a result, the water measurement error is almost zero. Furthermore, the meniscus can also be visually confirmed directly from the horizontal position.

ところで、加水発熱剤は、用途、目的に合わせて発熱剤の質量を増減して品番を揃えてあり、当然反応水の量の変えなければならない。従って、理想的には、またマーチャンダイジングの点からも、外装容器の容量も発熱剤の質量毎に対応させて製造することが望ましい。この場合、当然、外装容器開裂用のＶ型ノッチの位置も一律ではなく、反応水の計量線も、品番に応じて変える必要があるので、水計量線を形成するための水計量線形成用Ｖ型ノッチ９は、１品番に１個形成することになる。 By the way, the hydrothermal exothermic agent has the same product number by increasing / decreasing the mass of the exothermic agent according to the use and purpose, and naturally the amount of reaction water must be changed. Therefore, ideally, from the viewpoint of merchandising, it is desirable that the outer container has a capacity corresponding to the mass of the heat generating agent. In this case, as a matter of course, the position of the V-shaped notch for opening the outer container is not uniform, and the measuring line for the reaction water needs to be changed according to the product number, so that the water measuring line for forming the water measuring line is used. One V-shaped notch 9 is formed for each product number.

しかしながら、製造上のコストを低減するためには、１個の外装容器を、異なる量の発熱剤に兼用することが好ましい。この場合には、発熱剤の質量、即ち、反応水の量に応じて反応水計量線形成用Ｖ型ノッチ９を複数個設けることが好ましい。 However, in order to reduce the manufacturing cost, it is preferable to use one outer container as a different amount of heat generating agent. In this case, it is preferable to provide a plurality of V-shaped notches 9 for forming a reaction water measuring line in accordance with the mass of the exothermic agent, that is, the amount of reaction water.

前述した通り、本考案は、アルミ箔等の外装容器の内表面に水の計量線が印刷されていて、注水後、上から覗いて計量線に達しているか否かを確認する従来技術と異なり、アルミ箔等の外装容器を、外装容器開裂用Ｖ型ノッチの下方部において、予め発熱剤との発熱反応に必要な量の水を収容する容積を形成する位置に形成した折り曲げ線から折り曲げて形成した外装容器自体が所定量の反応水しか入らない計量カップとなるか、又は、アルミ箔等の外装容器を反応水計量線形成用Ｖ型ノッチから開裂して形成したカットライン自体が反応水の計量線となり、所定量の反応水しか入らない計量カップとなるので、メニスカスを水平位置から直接目視で確認できる、水の計量の誤差が殆どゼロになる。従って、発熱剤の水との発熱反応を過不足なく実施でき、発熱剤を効果的かつ経済的に利用でき、商品としての信頼性が向上する。また、正確な発熱反応を行うことが可能となるので、新たな用途の拡大、産業上の利用可能性が期待される。 As described above, the present invention is different from the conventional technique in which a water measuring line is printed on the inner surface of an outer container such as an aluminum foil, and after pouring water, it is checked whether the measuring line is reached from above. The outer container such as an aluminum foil is folded from a fold line formed in a position where a volume for storing an amount of water necessary for an exothermic reaction with the heat generating agent is previously formed in a lower portion of the V-shaped notch for opening the outer container. The formed outer container itself becomes a measuring cup that contains only a predetermined amount of reaction water, or the cut line itself formed by cleaving the outer container such as aluminum foil from the V-shaped notch for forming the reaction water measuring line is the reaction water. Since the measuring cup becomes a measuring cup that contains only a predetermined amount of reaction water, the meniscus can be visually confirmed directly from the horizontal position, and the error in measuring water becomes almost zero. Therefore, the exothermic reaction of the exothermic agent with water can be carried out without any excess, the exothermic agent can be used effectively and economically, and the reliability as a product is improved. In addition, since an accurate exothermic reaction can be performed, expansion of new applications and industrial applicability are expected.
