とを目的とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a dry pond. In dry batteries that are sealed with a synthetic resin sealing lid with a molded terminal cap, the sealing process [1] is improved by improving the method.
``The purpose is to prevent the seal from bursting due to an increase in the internal pressure of heavy oil.

は至っていない。However, the sealing effect cannot be improved due to the fact that the convex part itself has no work such as removal of scraps.
．． ) Abnormal discharges such as short circuits or reverse connection discharges At 1 o'clock, the seal 11 often bursts due to the rapidly increasing gas pressure inside the battery. Attempts have been made to eliminate the agent and seal the resin seal t1 with only 1-1, but in that case, it was not possible to sufficiently prevent moisture from escaping, and the voltage and voltage caused by internal drying of the battery during storage were reduced. Due to the inferiority of the current, it has not reached the actual level.

密封するものである。The method for producing dry market oil of the present invention largely eliminates the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings. 1 in Figure 1 is filled with power generation elements! ll! It is a lead can, and an internal material 11 and a filler 2 are injected through the flange 3 as in the conventional example. Filler 2' is also applied to the upper peripheral surface of the carbon rod 7.
is applied as shown in Figure 2. As shown in Fig. 3, the synthetic resin seal 11 on which the anode terminal cap 4 is molded and the inner surface of the lid 5 are provided with gas vents to remove gas, etc. inside the battery that increases rapidly during abnormal discharge such as short circuit or reverse connection discharge. A gas venting notch 8 is provided in the through hole of the carbon rod L''j゛j゛, and this gas venting notch 8 is a sealing part 8 of the terminal cap 4 molded with the resin of the seal 1-]@s. 1. Dry oil is sealed at the tip of the flange 10. To seal the oil, fill the flange 3 with asphalt or its mixture as an internal sealing filler 2 and inject it into the +111 lead can 1. At the same time, asphalt or a mixture thereof is applied in an annular manner to the upper peripheral surface of the carbon rod 7 as an internal material [] filler 2'.
Next, the anode end-r cap 4 molded on the resin lumber r3 lid 6 is fitted onto the upper end of the carbon rod 7. At this time, carbon rod 7
A part of the internal material 1-1 and the filler 2', which is annularly applied to the circumferential surface of the IM, is sealed with a resin seal [the guff removal notch 8 provided in a part of the carbon rod through hole 9 of the IM]. to seal the zinc can 1.

のである。In a dry cell manufactured by the method described above, the gas pressure inside the battery that increases when an abnormal discharge such as a short circuit or a reverse connection discharge occurs is not destroyed and the internal material 11 filler 2 asphalt or its mixture is The moon 11 is pushed into the gas venting notch 8 provided in the lid 5, and is pushed out around the tip of the flange 1o of the anode terminal cap 4, and the V1 horn inside the pond is pushed out. It is something that can be done. In this resin seal 1l hn5 (rII), the gas venting notch 8 provided in
In the present invention, it is completely filled with asphalt or a mixture thereof to completely seal the young fruit. This eliminates accidents such as rupture of a part of the seal caused by an increase in gas pressure within the battery, and also maintains the sealing effect under normal conditions to ensure a shelf life of 11.
