Claims

[Scope of utility model registration request]

(1) Inserting a sealing gasket into the opening of a cylindrical battery can filled with a power generation element, positioning this gasket by a ring-shaped part formed by bending along the outer periphery of the battery can, and In a dry battery, the open end of the battery can is caulked inward to compress the gasket and seal the inside of the battery can, and the outer periphery of the battery can is further bound and wrapped with a heat-shrinkable tube. , characterized in that the heat shrinkage rate of the heat-shrinkable tube is made different in the circumferential direction and the longitudinal direction of the battery can, and the heat shrinkage rate in the circumferential direction is relatively larger than the heat shrinkage rate in the longitudinal direction. Dry battery.

(2) In the dry battery of utility model registration claim (1), the heat shrinkage rate in the longitudinal direction is smaller than the heat shrinkage rate in the lateral direction, and the heat shrinkage rate in the longitudinal direction is regulated to 10% or less. Characteristic dry cell battery.

(3) In the dry battery of utility model registration claim (1) or (2), the heat-shrinkable tube has two or more heat-shrinkable film layers, and further has an adhesive layer on its inner surface. A dry battery characterized by having a metal plating layer between two heat-shrinkable film layers.
