    • Notches (21a, 21b) are formed at the corners of only one side edge (19a) of a metal jacket blank (19) of a rectangular metal strip. The blank (19) is rolled into a cylindrical shape so that its opposite sides (19a, 19b) are adjoined to each other forming an abutment joint (10) and a lower end (19c) of the blank (19) is inwardly curled and crimped to form a bottom, thus completing an outer metal jacket (18). After a cell member (26) is loaded into the metal jacket (18), the upper end (19d) of the blank (19) is inwardly curled and crimped to cause the notches (21a, 21b) to abut the other side edge (19b) of the blank (19), forming a curled abutment joint (20) along a direction (S) which is different from the radial direction (R) of the metal jacket (18). This arrangement prevents any dents caused by the buckling of the outer metal jacket (18) while being crimped, and allows dry cells to be more efficiently produced.
    • 切口(21a,21b)形成在矩形金属条的金属外壳坯件(19)的仅一个侧边缘(19a)的角部处。 将坯料(19)卷成圆柱形,使得其相对的侧面(19a,19b)彼此邻接形成邻接接头(10),并且坯料(19)的下端(19c)向内卷曲,并且 卷曲形成底部,从而完成外部金属外套(18)。 在将电池构件(26)装入金属护套(18)之后,坯件(19)的上端(19d)向内卷曲并卷曲,使得凹口(21a,21b)抵靠另一侧边缘 19),沿着与金属护套(18)的径向方向(R)不同的方向(S)形成卷边邻接接头(20)。 这种布置可防止由于外部金属护套(18)的弯曲而卷曲而引起的任何凹痕,并且能够更有效地制造干电池。

    • A manganese dry battery with excellent leak-proof property is provided, in which electrolyte leakage does not occur even if the size of a positive electrode material mixture is increased to meet a demand for improvement in discharge property. In a sealing part, a first circular projection, a second circular projection and a third circular projection are arranged at the bottom in sequence from the center to the outside, and a positive electrode carbon rod supporting part is provided in an innermost periphery portion to have an interval from the first circular projection. A groove between the first projection and the carbon rod is formed to have a substantially rectangular vertical section, kraft board is pressed by flat bottom surfaces of the first and second projections and an opening of the zinc can is fitted between the second and third projections.
    • 提供具有优异的防漏性能的锰干电池,其中即使增加正极材料混合物的尺寸,也不会发生电解液泄漏以满足放电性能的改善的要求。 在密封部分中,第一圆形突起,第二圆形突出部和第三圆形突起从中心到外面依次布置在底部,并且正极碳棒支撑部分设置在最内周边部分中以具有 从第一个圆形投影的间隔。 第一突起和碳棒之间的槽形成为具有大致矩形的垂直部分,牛皮纸被第一和第二突起的平坦底表面挤压,并且锌罐的开口装配在第二和第三突起之间。
