Abstract

PURPOSE:To enhance the airtightness of the contacting surface between a carbon bar and a sealing body, and constitute a dry cell with a good preservation performance by attaching the sealing body to the carbon bar, placing a hermetic sealing material on the sealing body around the carbon bar, and inserting a cylindrical heating member from the upside into the former contacting surface. CONSTITUTION:A carbon bar 5 the surface of which is treated with wax is passed through the penetration hole of an upper lid paper 4, and is pressed and fitted into the center of a positive mixture 3. A hermetic sealing material layer 6 is formed on the paper 4. After the opening of a zinc can 1 is curved inward, a sealing body 7 made of polyethylene is attached to the carbon bar 5 in such a manner that the outer periphery of the sealing body 7 touches the curved part of the can 1. A hermetic sealing material 11 is placed on the sealing body 7 around the carbon bar 5. A heated cylindrical heating member 12 is inserted from the upside to about one third of the entire length of the contacting surface between the bar 5 and the body 7, thereby melting the sealing material 11 and the sealing body 7 at the contacting surface. After the member 12 is raised, the body 7 and the material 11 are fused to the bar 5. Following that, a dry cell is manufactured according to a usual method.
