、最悪の場合、電池の破裂事故を招くおそれかあった。(Prior Art) It is known that alkaline dry batteries generate a small amount of gas during discharge or storage. In this case, with respect to the normal amount of gas generated, there is no problem with the battery itself or the device using the battery, or if charging is performed due to incorrect insertion into the device, an abnormal amount of gas may be generated. In the worst case scenario, there was a risk that the battery would explode.

Some have a gas exhaust function that allows the gas to be discharged.

化する欠点があった。(Problem to be Solved by the Invention) In alkaline dry batteries, electrocapillary action occurs between the negative potential of the electrode and the surface tension at the electrolyte interface, and oxygen gas in the air is sometimes reduced to OH-. There is a phenomenon in which electrolyte solution creeps up along the current collector rod due to an electrochemical reaction. Therefore, if the gas exhaust hole of the negative terminal plate is left open as described above, when the electrolyte moves along the inner surface of the terminal plate, it will flow to the outside through the gas exhaust hole. However, there was a drawback that the leakage resistance properties were significantly deteriorated.

ことを特徴とする。[Structure of the Invention (Means for Solving the Problems)] In order to achieve the above object, the present invention provides a thin wall portion that is provided at the opening of a cylindrical metal can filled with a power generation element and that is destroyed by gas pressure. In an alkaline dry battery formed by sealing an insulating gasket with a negative electrode terminal plate having a gas discharge hole through a metal support, the heat-melting substance softens and melts the gas discharge hole portion of the negative electrode terminal plate at 70 to 90°C. It is characterized by being coated with.

弁の機能を損なうことはない。(Function) According to the present invention, since a heat-melting substance is used and its softening and melting temperature is 70 to 90°C, the battery may be short-circuited during use or handling, or may be incorrectly inserted into equipment. When charging occurs, the intense battery reaction that occurs between the positive and negative electrodes of the battery causes rapid heat generation and rapid expansion of the gas inside the battery, but at such times the coating softens at the above temperature. , the function of the explosion-proof valve provided in the gasket will not be impaired.

けた防爆弁の機能に支障をきたす。If the softening and flowing temperature of a heat-melting substance is 69°C or lower, it will soften, melt and flow in a normal high-temperature environment, such as the interior of a car parked in direct sunlight; If the temperature is 91°C or higher, even if the battery is incorrectly charged or short-circuited, the heat generated will not cause softening and flow, which will impede the function of the explosion-proof valve provided in the gasket.
