である。FIG. 1 is an example of a button type battery. In the figure, 1 is a metal case having a rising portion 2 on the periphery, and a positive electrode mixture 3 is filled therein. 4 is a metal dish-shaped sealing lid with five sleeves around it, and six negative electrode materials are placed inside. Note that the outer diameter of the sealing lid is slightly smaller than the inner diameter of the rising portion of the case. 7 is a separator.

リアミド等の封止剤を介在せしめるのが普通である。As shown in FIGS. 2 and 3a, the shape of the gasket 8 includes a raised cylindrical portion 9 that is inscribed in the case rising portion 2 and circumscribed to the sleeve 5 of the sealing lid, and a lower end of the sleeve 6 of the sealing lid. It consists of a plane portion 10 circumscribed by . Furthermore, plane part 10
The tip of the cylindrical part 9 may be provided with an inward annular springing part 11 as shown in FIG. There are some things. A sealant such as asphalt or polyamide is usually interposed between the gasket 8 and the sealing lid sleeve 6 and between the gasket 8 and the case stand 2.

止する。The method for manufacturing this battery is generally to integrate a gasket 8 into a sleeve 5 on the periphery into a case 1 containing a positive electrode mixture 3, and insert a sealing lid 4 containing an anode material 6 and an electrolyte. The tip 13 of the case rising portion 2 is bent inward to seal it liquid-tightly.

現象から特にこの傾向が強い。The most important thing for such a battery is to prevent the electrolyte contained therein from leaking out through the gap between the case and the gasket or the sealing lid and the gasket. In particular, batteries often leak from the negative side, that is, between the gasket 8 and the sealing sleeve 5 in Figure 1, and the influence of the shape of the gasket, degree of fitting, sealant, etc. It is extremely large. This tendency is particularly strong in batteries using an alkaline electrolyte such as aqueous potassium because of the crease phenomenon of the electrolyte.

In order to achieve the above-mentioned object, the present invention includes a rising cylindrical part that inscribes the gasket in the case and circumscribes the sealing lid, a part that circumscribes the lower end of the periphery of the sealing lid, and a part that inscribes the inner surface of the sleeve of the sealing lid. The sleeve is characterized in that a portion inscribed in the sleeve is provided with an annular protrusion extending outward.

実施例の説明
以下、本発明の実施例を第４図〜第６図により説明する
。DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIGS. 4 to 6.

外側に斜めに延出するようになったもの等がある。Figure 4 shows an example of a button type battery, with a gas tube and a nozzle 8'.
Everything below is the same as the conventional example shown in FIG. As shown in FIGS. 6 and 6a, the gasket 8' is inscribed in the rising part of the case, has a vertical cylindrical part 9' that circumscribes the sleeve 6 of the sealing lid 4, and circumscribes the lower end of the sleeve of the sealing lid. It consists of a flat portion 10' and an inner cylindrical portion 14 inscribed on the inner surface of the lid sleeve of the seal 1, and the inner cylindrical portion 14 is provided with an annular protrusion 15 extending outward. Therefore, the outer diameter φ1 of the inner cylindrical portion 14 is smaller than the maximum outer diameter φ2 of the annular projection 15. The shape of the annular protrusion 15 may be, for example, one located near the upper end of the inner cylindrical portion 14 as shown in FIG. There are some that extend diagonally outward.
本発明の電池に用いるガスケットは、このような形状を

る。Since the gasket used in the battery of the present invention has such a shape, when the sleeve of the sealing lid is fitted into this gasket, the inner cylindrical portion, especially the annular protrusion, presses the sealing lid sleeve strongly. This makes it difficult for the electrolyte to penetrate. As a result, the leakage resistance of the battery is significantly improved.
