しめるとともに、下端に折曲部５を形成する。A cathode terminal plate 3 having a horizontal portion 2 on the periphery is attached to the bottom of a zinc can 1 containing power generation elements such as an anode mixture, carbon rods, and separators.The sides of the waist zinc can 1 are covered with heat-shrinkable polyvinyl chloride. It is covered with a resin tube 4 made of a tube or the like, and the resin tube 4 is heat-shrinked to be brought into close contact with the side surface of the zinc can 1, and a bent portion 5 is formed at the lower end.

Surface hardness measured by MD-785 method is approximately 70-12
The surface hardness of the resin tube 4 is preferably made of a block polymer of ethylene and propylene containing about 3 to 1% ethylene, regulated within the range of C1if or 85 to 11O (Rockwell, R scale). The opening angle θ of the annular protrusion 7 is approximately 60° to 120°.
0 preferably 80° to 1000°, and the height of the annular protrusion 7 is regulated within a range of about 0.2 to 0.577 CI11.

に局部的に圧着されている。This seal ring 6 is formed between the horizontal portion 2 of the cathode terminal plate 3 and the lower bent portion 5 of the resin tube 4 by the tightening force of the lower end curl 9 of the metal exterior can 8 fitted to the outside of the resin tube 4. The clamping force is concentrated on the tip of the annular protrusion 7, causing the cathode terminal plate 3 and the resin tube 4 to be compressed.

弾発力により両者の接合部を液密にする必要がある。Since the resin tube 4 and the seal ring 6 are both made of synthetic resin, it is easy to obtain a flat contact surface, and the annular protrusion 7 is not necessarily required because the elasticity of the resin tube 4 and the seal ring 6 are both made of synthetic resin. has no surface elasticity and is prone to minute irregularities on its surface due to scratches or variations in plating. It is necessary to use force to press the tip of the annular protrusion 7 against the cathode terminal plate 3 to deform it, and to use the elastic force to make the joint between the two liquid-tight.

0 (Rockwell, R scale), annular protrusion 7
By restricting the opening angle θ to a range of about 60° to 120° and combining them, the effect of the annular protrusion 7 on the cathode terminal plate 3 can be fully exhibited, and it is effective in preventing liquid leakage.

に阻止でき、耐漏液性に優れた乾電池が得られる。As described in the embodiment, a chevron-shaped annular protrusion 7 is formed on the lower surface of the seal ring 6 having the above-mentioned surface hardness, and a resin tube 4 having a surface hardness slightly lower than that of the seal ring 6 is used. If the tip of the annular protrusion 7 is pressed against the resin tube 4 by tightening the outer can 8 and the resin tube 4 is locally compressed, leakage of the electrolyte can be further effectively prevented, resulting in excellent leakage resistance. A dry battery can be obtained.
