本発明は小型アルカリ電池の改良に係り、幼児などがち
や゛まって飲み込んだ場合に磁石で取り出しやすくした
小型アルカリ電池を提供することを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in small-sized alkaline batteries, and an object thereof is to provide a small-sized alkaline battery that can be easily removed using a magnet if it is accidentally swallowed by an infant or the like.
最近、ゲーム機、ゲームクオツチなどの子供向は電池応
用機器の普及に伴ない幼児があやまって電池を飲み込む
という事故が多発している。Recently, with the spread of battery-based devices such as game consoles and game consoles for children, there have been many accidents in which young children accidentally swallow batteries.
そして、こうした誤飲事故があった場合、できるだけ早
く電池を体内から取り出さないと電池が胃の中で破壊さ
れ、アルカリ電解液などの有害な内容物が体内に流出し
て人体に危害を及ぼすおそれがあると報じられている。If such an accidental ingestion occurs, if the battery is not removed from the body as soon as possible, the battery may be destroyed in the stomach and harmful contents such as alkaline electrolyte may leak into the body, causing harm to the human body. It is reported that there is.
そこで、電池を体内から取り出す方法として磁石で電池
を吸いつけて取り出す方法が提案されているが、小型の
アルカリ電池では高容量化をはかるために正極缶の缶材
を薄くする必要があり、そのため強度面や加工性の観点
から従来使用の鉄（て代えてオーステナイト系のステン
レス鋼を正極缶に用いることが多くなってきた。Therefore, a method has been proposed to remove the battery from the body by attracting the battery with a magnet, but in order to increase the capacity of small alkaline batteries, the material of the positive electrode can must be made thinner. From the viewpoint of strength and workability, austenitic stainless steel is increasingly being used in positive electrode cans instead of conventionally used iron.
ところがオーステナイト系のステンレス鋼は強磁性体で
はないため磁石にすＡつかず、また負極端子板も非強磁
性体であるオーステナイト系のステンレス鋼を母材とす
る関係上、強磁性体が外面側の薄いニッケル層だけとな
り、その薄いニッケル層だけでは磁石による吸着力が弱
く、電池を狭い幼児の食道などを通して胃の中から取り
出す間に電池が磁石からｌ−ｉずれ、体外へ取り出し得
ないという事態が発生する。However, since austenitic stainless steel is not a ferromagnetic material, it cannot be used as a magnet, and since the base material of the negative terminal plate is austenitic stainless steel, which is a non-ferromagnetic material, the ferromagnetic material is on the outer surface. There is only a thin nickel layer on the battery, and this thin nickel layer has a weak adsorption force with the magnet, and while the battery is removed from the stomach through the narrow esophagus of an infant, the battery slips away from the magnet and cannot be removed from the body. A situation occurs.
本発明はそのような事情に鑑みてなされたものであり、
正極缶にオーステナイト系ステンレス鋼を用いる小型ア

極端子板側を強磁性体にし、高容量化の達成とともに、
誤飲事故が生じたときに電池を磁石で容易に取り出し得
るようにしたものである。The present invention was made in view of such circumstances,
In small alkaline batteries that use austenitic stainless steel for the positive electrode can, the negative terminal plate is made of a cladding plate that has a copper layer as a mating material and a ferritic stainless steel layer as a base material, which is placed inside the battery. By making the plate side ferromagnetic, we achieved high capacity and
The battery can be easily removed using a magnet in the event of accidental ingestion.
本発明において負極端子板に用いるクラツド板としては
、フェライト系ステンレス鋼を母材とし合せ材として銅

ラツド板や、フェライト系ステンレス鋼を母材とし合せ
材として一方の面に銅を、他方の面にニッケルを用すた
銅−７エライト系ステンレス鋼−ニッケルよりなる３層
クラツド板などがあげられる。In the present invention, the clad plate used for the negative electrode terminal plate may be a two-layer clad plate made of copper-ferritic stainless steel using ferritic stainless steel as the base material and copper as the mating material, or a two-layer clad plate made of ferritic stainless steel as the base material and copper as the mating material. Examples include a three-layer clad plate made of copper-7-elite stainless steel-nickel with copper on one side and nickel on the other side as a laminate.
フェライト系ステンレス鋼としては例えば５ＵＳ４０５

ＵＳ４３４などが用いられ、これらのフェライト系ステ
ンレス鋼は強度面や磁性面の関係から上記クラツド板に
おいて１５０μｍ以上の厚さにすることが望ましい。For example, 5US405 is an example of ferritic stainless steel.
．． 5US429.5US430.5US430F, 5
US434 or the like is used, and it is desirable that these ferritic stainless steels have a thickness of 150 μm or more in the above-mentioned clad plate from the viewpoint of strength and magnetic properties.
なお磁性面か、らだけいえばニッケルを負極端子板に用
することも考えられるが、強度面から採用しが′たい。From a magnetic point of view, it is possible to use nickel for the negative terminal plate, but this is difficult to do from a strength standpoint.
上記クラツド板よりなる負極端子板ｔｃおいて、銅層は
アルカリ電池の通例に従って電池内部側に配置される。In the negative terminal plate tc made of the above-mentioned clad plate, the copper layer is arranged inside the battery as is customary for alkaline batteries.

Examples include US885. By using these stainless steels, the thickness of the can material can be reduced by about 50 to 100 μm compared to conventional iron cans, and the amount of active material filled can be increased accordingly.

In addition, the base material of the clad plate used for the negative terminal plate is austenitic stainless steel, which is a non-ferromagnetic material, and the only ferromagnetic material is the thin nickel layer on the outer surface, so it sucks up the entire battery (but it does not). That's enough.
