【考案の詳細な説明】
生石灰（CaO）に水を加えると発熱反応して消
石灰を生ずることは周知の事実である。[Detailed description of the invention] It is a well-known fact that when water is added to quicklime (CaO), an exothermic reaction occurs to produce slaked lime.
CaO＋H2O→Ca（OH）2＋15.2Kcal

の欠点がある。CaO+H 2 O→Ca(OH) 2 +15.2Kcal A method of heating retort food stored in a bag by utilizing this exothermic reaction is also known. Quicklime is in direct contact with the exterior material, and neither quicklime nor slaked lime is edible and cannot be said to be sanitary. Furthermore, in Japanese Utility Model Publication No. 52-28711 and Japanese Utility Model Publication No. 58-105880, quicklime and food are placed in separate bags to prevent quicklime and slaked lime from adhering to the exterior packaging material of the food. It has poor thermal conductivity. All of the above three publications describe the use of powdered, granular, or lump quicklime; quicklime tends to shift downward due to gravity, making it difficult to heat uniformly, and making it tiltable. There are disadvantages such as water spillage.
本考案は上記のような欠点を改善するためにな
されたもので以下本考案を図示の実施例により説
明する。 The present invention has been made to improve the above-mentioned drawbacks, and the present invention will be explained below with reference to illustrated embodiments.
第１図は本考案の簡易加熱材料およびその応用
についての説明図で１は生石灰をプレス成型加工
により板状に成型したものである。 FIG. 1 is an explanatory diagram of the simple heating material of the present invention and its application. Figure 1 shows quicklime molded into a plate shape by press molding.
２は吸水性板状物質で例えばスポンジ、圧縮パ
ルプシートなどである。この吸水性板状物質２の
中心に上端面からスリツト３を設け、板状生石灰

発熱するようにしたものである。 2 is a water-absorbing plate-like material such as a sponge or a compressed pulp sheet. A slit 3 is provided in the center of this water-absorbing plate-like material 2 from the upper end surface, and the plate-like quicklime 1 is inserted into this slit 3. That is, a plate-shaped quicklime 1 is sandwiched between water-absorbing plate-shaped substances 2, and water is absorbed from the outside by the water-absorbing plate-shaped substances, expands it, and at the same time penetrates into the interior and reacts with the quicklime to generate heat. It is.

食品を二つの加熱材料Ａでサンドイツチするよう
に入れてもよい。生石灰は空気中の水分を吸収す
るので使用時まで加熱材料Ａを入れた部分は密封
しておくことが必要である。 Such a heat generating material A is stored in a bag B and used, for example. As the bag, a plastic film such as polyethylene or polypropylene, and a laminate of the same and aluminum foil are used.The bag is divided into, for example, three compartments, and the intermediate film, which does not contain aluminum, as shown in the figure is used. The central chamber 4 is for storing packaged retort foods, etc., and the heating material A is placed in the spaces 5 on both sides. The bag does not necessarily have to be divided into three compartments, and food may be sandwiched between two heating ingredients A in one bag. Since quicklime absorbs moisture from the air, it is necessary to seal the area containing heating material A until use.
使用時には第１図に示すように上端部で袋を開

反応して発熱し吸水性板状物質は膨脹して食品の

６がＷ型となつているものを使用すれば加熱時も
安全である。 When in use, as shown in Figure 1, when the bag is opened at the top end and excess water is poured into the heating material A, the quicklime reacts with the water and generates heat, causing the water-absorbing plate-like material to expand and adhere tightly to the food bag. Water acts as a heat transfer medium and has good heat transfer efficiency because it adheres well to food. If the bag B has a W-shaped bottom 6, it will be safe even when heated.
本考案の簡易加熱材料を用いる他の例として第
２図に示すような手段もある。７は断熱カートン

けば、その発熱効率が一層向上する。 Another example of using the simple heating material of the present invention is as shown in FIG. 7 is an insulated carton with an outer wall made of water-resistant cardboard, and 8 is a zipper for opening. A water-impermeable plastic film 9 is formed into a bag shape on the inner wall, and a simple heating material A is housed inside the inner wall, and a retort food or the like is placed between the simple heating materials A. Note that if the necessary water is measured and prepared in advance by placing it in a suitable container 10, the heat generation efficiency will be further improved.
本考案の簡易加熱材料は板状となつているので
重さによつて、粉末、顆類あるいは塊状の生石灰
でないので一方に片寄り、従つて不均一な加熱が
起らない点で非常に優れており吸水した板状物質
が密着するので熱効率もよく、食品の包装材料の
外面を汚すということもないうえに、水が吸収性
物質に含浸保持されるので傾けてもこぼれること
がない等の利点がある。 The simple heating material of the present invention is in the form of a plate, so depending on the weight, it is not powder, granules, or chunks of quicklime, so it tends to be biased to one side, so it is very superior in that it does not cause uneven heating. The absorbent material adheres tightly to the material, resulting in good thermal efficiency and does not stain the outer surface of the food packaging material.Water is impregnated and retained in the absorbent material, so it does not spill even if it is tilted. There are advantages.
