The above-mentioned outer can is usually a cylindrical one made by rolling a thin metal plate and abutting each other, and the abutting both ends are double-folded to form a double lock outer can. Butt outer can type, or both ends are laser welded. And, generally, the upper end in the axial direction of the outer can is curled approximately 180 degrees inward, and the curled peripheral end is pressed against the insulating washer, while the lower end is bent approximately 90 degrees inward. Flat curls,

In a manganese dry battery having this structure, gas is generated inside the battery when the battery is left in a high-temperature atmosphere at a temperature of 70 ° C. or higher, or when the battery is used abnormally such as charging or reverse mounting. This gas exits from the contact surface between the zinc can opening and the sealing gasket and accumulates between the outer periphery of the zinc can and the heat-shrinkable resin tube. It is slowly and slowly released from the heat-shrinkable resin tube and the positive electrode terminal plate to the outside of the battery through the tubes.

<Problems to be solved by the invention> By the way, the capacity of this type of manganese dry battery is being increased in accordance with the increase in the output of various electric devices powered by this battery. When the battery is abnormally used, the rate of gas generation from the inside of the battery becomes sharp, and the amount of gas generated increases.

For this reason, it is difficult to perform degassing from the positive electrode side fastening portion of the outer can in accordance with the gas generation as described above, and degassing cannot be performed in time. The generated gas accumulates in the space or inside the battery, and the internal pressure of the battery rises, and the internal pressure rise causes deformation of the positive electrode terminal plate, the negative electrode terminal plate or the outer can, etc.
Furthermore, there is a problem that the positive electrode terminal plate comes off due to the internal pressure and the inside of the battery scatters outside.

An object of the present invention is to provide a manganese dry battery capable of reliably releasing generated gas to the outside of the battery without causing such deformation or detachment even when the capacity is increased.

<Means for Solving the Problems> The manganese dry battery of the present invention has a gas vent groove formed on the periphery of the upper surface of the sealing gasket placed on the opening of the zinc can containing the power generating element, and includes this gas vent groove. The peripheral edge of the upper surface is covered with the peripheral end of the heat-shrinkable resin tube that shrinks and binds the outer periphery of the zinc can, and the outer peripheral flange is degassed on the sealing gasket and the peripheral end of the heat-shrinkable resin tube. The main feature is that a positive electrode terminal plate having a hole or a notch formed therein is mounted thereon, and an insulating washer mounted on an upper surface of the outer peripheral flange portion is further tightened at a curl peripheral end of the outer can.

At least one gas vent groove in the sealing gasket or one gas vent hole or notch in the positive electrode terminal plate may be provided, but two or more gas vents are required to perform gas venting uniformly and without pressure imbalance. Preferably, two or more of these are formed on the positive electrode terminal plate and the sealing gasket at symmetrical positions, that is, at substantially equal intervals.

The gas vent groove and the gas vent hole or notch do not always need to be aligned. Even if they do not match, the generated gas inside the battery flows from the gas vent groove to the gas vent hole or notch through the space between the sealing gasket and the positive electrode terminal plate.

The gas vent hole or notch provided on the positive electrode terminal plate
It is preferable to completely cover and hide with an insulating washer placed on the upper surface of the outer peripheral flange portion of the positive electrode terminal plate because the liquid leakage resistance is improved. In addition, it is preferable that at least the inner end of the battery vent hole or notch on the inner peripheral side of the battery be located inside the press-contacted portion by the curl peripheral edge of the outer can, from the viewpoint of smooth venting.

<Effect> By providing a gas vent mechanism including a gas vent groove and a gas vent hole or notch as described above,
The gas generated inside the battery passes through the inside of the heat-shrinkable resin tube from the contact surface between the opening of the zinc can and the sealing gasket, passes through the gas vent groove and the gas vent hole or notch, and passes through the positive electrode terminal plate. A path is formed between the battery and the insulating washer and discharged to the outside of the battery.
