Description
【考案の詳細な説明】 〈産業上の利用分野〉 この考案は、発電要素を収納した有底円筒状の電池缶の
外周をフィルムジャケットにて被包して構成される筒形
電池に関するものである。[Detailed Description of the Invention] <Industrial application field> The present invention relates to a cylindrical battery configured by enclosing a battery jacket having a bottom and a bottomed cylindrical battery can with a film jacket. is there.
〈従来の技術〉 例えば筒形アルカリ電池では、従来より、発電要素を収
納した素電池の外面に、金属薄板からなる外装缶を装着

わゆるフィルムジャケットを素電池外面に装着して完成
電池とする構成が広く用いられてきた。<Prior Art> For example, in a cylindrical alkaline battery, conventionally, a configuration in which an outer can made of a thin metal plate is attached to the outer surface of a unit cell accommodating a power generation element has been used recently, but in place of this, A structure in which a so-called film jacket is attached to the outer surface of a unit cell to obtain a completed battery has been widely used.
この種のフィルムジャケットを外装とした場合、素電池
を大きくできるため、メタルジャケットを用いた構成に
比べて発電要素収納量が増大し、電池放電容量が増加す
るという利点がある。When this type of film jacket is used as the exterior, the unit cell can be made larger, and therefore, there is an advantage that the storage amount of the power generation element is increased and the battery discharge capacity is increased as compared with the configuration using the metal jacket.
上記のフィルムジャケットとしては、一般に、金属光沢
処理を施した合成樹脂製ラベル、あるいはポリ塩化ビニ

熱収縮させて緊縛巻回して素電池外面に被着させてい
る。As the above film jacket, generally, a synthetic resin label that has been subjected to a metallic luster treatment, or a heat-shrinkable resin tube such as polyvinyl chloride resin is used, and these are fixed with an adhesive or the like. Alternatively, it is heat-shrinked and tightly wound and attached to the outer surface of the unit cell.
〈考案が解決しようとする課題〉 しかしながら、上記のようなフィルムジャケットは、そ

う際などに破れることがある。そして、例えば、電池ケ
ース内でフィルムジャケットの(-)側を傷付け破った電
流取出し用バネ端子の先端が電池缶開口部と端子板とを
短絡して、ショートが発生することが起こり易い。<Problems to be solved by the invention> However, the film jacket as described above has a thickness as thin as about 0.1 mm and therefore has a mechanical strength considerably weaker than that of the metal jacket. Therefore, the battery may be broken when it is put in the battery case or when the battery is handled. Then, for example, the tip of the current-extracting spring terminal that damages the (−) side of the film jacket in the battery case and shorts the battery can opening portion and the terminal plate easily causes a short circuit.
また、電池製造工程において、電池の外面にラベルを巻
く際、素電池との位置関係により、装着位置が(+)側に
ずれてしまうことがある。そしてこの場合、ラベルの長
さは、電池ごとに決まっているので、(+)側にずれた分
だけ電池缶開口部側が露出してしまい、電池ケース内に
入れた時などに(-)側の電流取出用端子により電池缶開
口部と端子板とが同様に短絡するという問題がある。Further, in the battery manufacturing process, when the label is wound on the outer surface of the battery, the mounting position may be shifted to the (+) side due to the positional relationship with the unit cell. And in this case, the length of the label is determined for each battery, so the battery can opening side is exposed by the amount shifted to the (+) side, and when it is placed in the battery case, the (-) side is exposed. There is a problem that the battery can opening portion and the terminal plate are similarly short-circuited by the current extracting terminal.

位置する部分が変形し易く、外観性が低下するため、例
えば熱収縮させて装着する場合、加熱時に凹ませないよ
うに注意しつつ作業を行なう必要があり、工程や取扱が
煩雑化するという不都合もある。Further, in a battery of the type in which the opening of the battery can is beaded and the insulating packing supported by pressure between the opening and the terminal plate is supported, the film jacket located above the beading is deformed by external force, Further, the surface of the battery can may be exposed by being torn. Also, even when the film jacket is attached, the part of the jacket located on the beading of the battery is easily deformed, and the appearance is deteriorated.For example, when heat-shrinking and attaching the film jacket, be careful not to dent it when heating. However, it is necessary to carry out the work while making the process and handling complicated.
このため、フィルムジャケットを厚くして上記のような
ショートや変形などを防止することも考えられるが、フ
ィルムジャケットを厚くすればその剛性が大きくなるか

う不都合がある。Therefore, it is possible to make the film jacket thicker to prevent the above-mentioned short-circuiting or deformation, but if the film jacket is made thicker, its rigidity becomes larger, so that the label attached to the outer surface of the unit cell is easily peeled off. There is an inconvenience.

るように保持したことを要旨とする。<Means for Solving the Problems> In the cylindrical battery of the present invention, a beading portion is formed on the outer periphery of the opening of a cylindrical battery can with a bottom filled with a power generating element, and the opening is formed as an insulating packing. A cylindrical battery in which the outer surface of a unit cell formed by combining and sealing a terminal plate is covered with a film jacket, and an insulating case having an inward bent portion protruding toward the opening side of the battery can is attached to the battery can. The gist is that the beading portion is held so as to cover the outer surface and the inner surface of the film jacket.
〈作用〉 上記のような絶縁性ケースを設けて電池缶開口部を保護
することにより、フィルムジャケットの破れやズレに困
る短絡が防止される。<Operation> By providing the above-described insulating case to protect the opening portion of the battery can, it is possible to prevent a short circuit which is troubled by breakage or displacement of the film jacket.
また、絶縁性ケースによってビーディング部の凹みがカ

なる。In addition, the insulating case covers the depression of the beading portion, so that the film jacket can be prevented from being deformed by an external force or the like, and even if it is torn, the surface of the battery can is not exposed.

The insulating case 9 has a cylindrical shape with an L-shaped cross section as shown in FIG. If the insulating case 9 is too thick, it may have a large step when the film jacket is mounted on the insulating case 9 and the outer diameter may be out of the standard. Use something thinner than this. Further, in order to provide necessary strength or rigidity even if it is thin, it is made of, for example, polyester or vinyl chloride-based synthetic resin.
そして、この絶縁ケース９の内方折曲部９ａは、電池缶
開口部の端部より更に内側まで位置し、端子板中央に形
成された突出部の外周面付近まで延在している。The inward bent portion 9a of the insulating case 9 is located further inside than the end portion of the battery can opening and extends to the vicinity of the outer peripheral surface of the protruding portion formed at the center of the terminal plate.

A film jacket 10 made by laminating an aluminum vapor deposition layer, a polyvinyl chloride resin layer, a printing layer, a cannabis varnish layer, etc. is attached by, for example, heat shrinking after adhesion. At this time, the end of the film jacket 10 on the side of the battery can opening is bent inward as shown in the drawing, and the insulating case 9 is bent.
The inner bent portion 9a is covered.
