【発明の詳細な説明】
〈産業上の利用分野〉
本発明は食品や人体を保温するための蓄熱保温体に関す
る。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a heat storage body for keeping foods and the human body warm.
〈従来の技術〉
従来、持ち運びする食品の保温にはジャーが多く用いら
れているが使い捨てにすることは出来ない、それが可能
な発泡スチロールのような断熱容器では長時間の保温は
望めない。<Conventional Technology> Conventionally, jars have been widely used to keep food warm when carried around, but they cannot be made disposable, and insulated containers such as styrofoam, which can do this, cannot be expected to keep food warm for long periods of time.
一方、身体の保温には上記の食品とは異なり。On the other hand, unlike the above foods, it helps keep your body warm.
古くから湯たんぽや白金カイロのように熱源をもちいて
いた。前者は顕熱型蓄熱材として比熱の高い水を用いて
いるが、かさばる欠点がある。後者は燃焼熱を用いたも
のなので少量で多くの熱カロリーを出すことができるが
、危険性が高いことや。Heat sources have been used since ancient times, such as hot water bottles and platinum body warmers. The former uses water with high specific heat as a sensible heat storage material, but has the disadvantage of being bulky. The latter uses combustion heat and can produce a large amount of calories with a small amount, but it is also highly dangerous.
高価なので使い捨てにするわけにはいかない。It's expensive so I can't just throw it away.
そこで最近では、身体の保温には鉄粉の酸化熱を利用し
た使い捨てカイロが多く使われている。Recently, disposable body warmers that utilize the oxidation heat of iron powder are increasingly being used to keep the body warm.
食品の保温にもこの原理を応用したものがあるが。This principle is also applied to keeping food warm.
６０°Ｃ以上の温度を長時間維持させる為には酸素の取
り入れ方法や、水分の蒸発防止方法などの工夫が難しい

を利用したものもあるが短時間の発熱なので持続性がな
い、さらに両者とも水蒸気が発生するのでご飯、シュー
マイ、肉マンシュウなど、蒸気でふかす食品の保温には
好ましいが。In order to maintain temperatures over 60°C for long periods of time, it is difficult to find ways to introduce oxygen or prevent water evaporation, and there are also methods that utilize the heat of hydration generated when water is added to calcium oxide. However, since they generate heat for a short period of time, they are not sustainable.Furthermore, both of them generate water vapor, so they are suitable for keeping foods that are steamed warm, such as rice, shumai, meatballs, etc.
ピザパイ、タイ焼き、お好み焼きなど鉄板やオーブンで
焼いて作る食品には向かない。It is not suitable for foods that are baked on a griddle or in the oven, such as pizza pie, Thai-yaki, and okonomiyaki.
また上記の保温体は繰り返し使用することは出来ない。Furthermore, the above-mentioned heat insulating body cannot be used repeatedly.
〈発明が解決しようする問題点〉
本発明の目的は食品や身体を保温するために安価で毒性

い、この条件を満たすものとして多価アルコール類が選
ばれた。In addition, the polyhydric alcohols used in the present invention are mixed so that they can be heated by microwaves generated from a microwave oven.Usually, water molecules are selected for those heated by microwaves, but in the present invention, water molecules are selected. are excluded. The reason for this is that when water molecules are mixed with the heat storage material, water vapor is generated while the heat storage heat insulator is being heated and melted using microwaves, which may cause the heat storage material storage container or bag to expand and be destroyed. It is. In order to avoid such dangers, a compound that can be heated with microwaves must be selected whose boiling point is as high as possible than the melting point of the heat storage material, and polyhydric alcohols were selected as meeting this condition.
多価アルコール類のうち本発明に最も好ましい物はＯ１
ｌ基の多い高沸点化合物で、具体的にはグリセリンまた

で粉末状に粉砕して均一に混合するのが好ましい。The blending ratio of glycerin or polyethylene glycol may be 1 to 20%, and may be determined in detail depending on the intended melting point of the heat storage material. However, it has a lower heat capacity than urea or ammonium nitrate, has poor fluidity during mechanical filling, and is expensive.
-10% is most preferred. Average molecular weight is 1000-60
Since polyethylene glycol No. 00 is solid at room temperature, it is preferable to grind it into a powder and mix it uniformly.
本発明品の蓄熱材収容容器または袋はマイクロ波を透過

が耐熱性に優れている。Ceramics, paper, resins, and composites of these can be used, but containers or bags made of laminates of multiple resin films or cardboard and resin films have strong impact resistance and are easy to process.Resin films can be made of polyethylene. , polypropylene, nylon, polyethylene terephthalate polycarbonate and other high melting point films can be used. In the case of laminated films, polyethylene is usually used on the inner surface to provide heat-sealing properties, but this material cannot withstand temperatures above 90'C.
Polypropylene can be used for the storage bag for the heat storage material having a melting point of 0 to 110°C. As an example of a laminate film that can be heat-sealed in this case, a laminate film of polyethylene terephthalate (12 microns)/nylon (15 microns)/polypropylene (80 microns) has excellent heat resistance.
