【発明の詳細な説明】
〈産業上の利用分野〉
この発明は、電池缶と端子板とを組合せてなる電池ケー
ス内に発電要素を密封収容した乾電池に関するものでお
る。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a dry battery in which a power generating element is hermetically housed within a battery case formed by combining a battery can and a terminal plate.
〈従来の技術〉

ースに密封収容する構成が用いられている。<Prior art> For example, in a cylindrical battery such as a cylindrical alkaline battery, a battery case is made of a cylindrical battery can with a bottom and a disc-shaped terminal plate positioned at the opening of the battery can, and a positive electrode and a negative electrode are connected to each other. A configuration is used in which a power generating element, which is formed by opposing the two with a separator interposed therebetween, is hermetically housed in this battery case.

電池とする構成が広く用いられている。When packaging the battery case of this type of cylindrical battery, conventionally, as shown in FIG. 2 (8), for example, as shown in FIG. Exterior can 1 made of a thin metal sheet, insulating a shrinkable tube without binding it, and further providing a printed layer on the surface.
A configuration in which a completed battery is made by attaching the battery 0 with insulating washers 9 interposed above and below is widely used.

ただけのものも用いられている。In addition, as shown in FIG. 2(B), a printed paper label 11 with a thickness of 0.2 mm fZ degree is wrapped around the outer periphery of the battery case.
There is also known a type in which a transparent or semi-transparent heat-shrinkable duvet 12 with a thickness of about 0.1 mm is placed over it and bound. In addition, recently, instead of using paper labels, labels with a thickness of 0.1 are made by laminating printed layers, heat-shrinkable tubes, etc.
Some devices are also used in which a small amount of exterior label is wrapped directly around the outer periphery of the battery case.
〈発明が解決しようとする問題点〉
しかしながら、上記外装缶を用いた形式では、電池外装
に用いる部品点数が多くまたコスト高となるばかりか、
電池ケースの径を規格寸法の完成電池より一廻り以上も
小さくしなければならず、電池ケースの発電要素収容量
が少なくなるので電池の放電容量が小さく制限されると
いう問題がある。<Problems to be Solved by the Invention> However, in the case of using the above-mentioned outer can, not only the number of parts used for the battery outer case is large and the cost is high.
The diameter of the battery case must be made more than one size smaller than that of a completed battery with standard dimensions, and the capacity of the battery case to house the power generating elements is reduced, resulting in a problem that the discharge capacity of the battery is limited.
また、紙ラベルの上に熱収縮性デユープをかけたものや

絡を起こし易いという問題かめる。また、必要な機械的
強度を得るため厚めのフィルム材料を用いなければなら
ず、その分電池ケース径を小さくなるから、上記同様電
池放電容母が小さいという問題もある。In addition, in the case of a paper label covered with a heat-shrinkable dupe or an exterior label, the structure is such that a film material, which has considerably inferior mechanical strength compared to a thin metal plate, is placed around the battery periphery, so it is difficult to handle it. There is a problem in that the surface of the battery case exposed from the scratches comes into contact with the terminal surface and is likely to cause an external short circuit. Furthermore, in order to obtain the necessary mechanical strength, a thicker film material must be used, which reduces the diameter of the battery case, resulting in the same problem as above that the battery discharge capacity is small.
〈問題点を解決するための手段〉
この発明の乾電池は発電要素を密封収容すると共に表面
に印刷層を直接設けた電池ケースの表面に、絶縁性の紫
外線硬化樹脂溶液を塗布し紫外線を照射して凝固させて
なる紫外線硬化樹脂層を設けたことを要旨とする。<Means for Solving the Problems> The dry battery of the present invention is made by applying an insulating ultraviolet curing resin solution to the surface of the battery case, which seals the power generation element and has a printed layer directly on the surface, and then irradiating it with ultraviolet rays. The gist is that an ultraviolet curable resin layer is provided by solidifying the resin.

必要十分でおることが知得されている。This ultraviolet curable resin solution becomes an ultraviolet curable resin having a pencil hardness of 4H1 and an elongation rate of about 10% after being solidified by ultraviolet irradiation. It is known that when such a layer of ultraviolet curing resin is used for the exterior of a battery case, a layer thickness of about 0.05 mm is necessary and sufficient.

る。Effects> By using the above means, it is possible to use a battery case that has approximately the same diameter as a completed battery of standard dimensions, and the capacity of the power generating element accommodated within the battery case is considerably increased. Furthermore, since the ultraviolet curable resin has a high hardness, it can be practically prevented from being scratched during handling.

Next, as shown in FIG.
