At the same time, it is publicly known that the electric NM main body, the liquid port tube that projects from the main body, and the diaphragm that seals the liquid port tube are molded. teeth,
Before the battery is used, it serves to ensure that the plates inside the battery are not exposed to the outside air and oxidized. Allows injection of electrolyte and refill water within 1m,
After injecting the liquid, a liquid spout plug is attached to the liquid spout cylinder and the liquid is used.

ばである。In this way, the diaphragm must ensure the sealing of the liquid opening before using the battery, and must be easily torn during use.
It is necessary to satisfy two conditions, but after the diaphragm is damaged,
A portion of the diaphragm often remains and obstructs liquid injection.

ロスをもたらすことがある。As an improved version of this diaphragm, in the integral molding of the battery lid,
The diaphragm has a relatively thick central part and a relatively thin annular recess at the periphery, so that when the diaphragm is pushed through, it will be torn annularly at the annular recess and no diaphragm will remain in the liquid port cylinder. Japanese Utility Model Publication No. 43-31791 discloses a method that eliminates the problems of the conventional method in which the remaining diaphragm portion makes it difficult to pour liquid, and the liquid splashes or leaks to the outside. However, when a diaphragm having such a shape is formed by molding, weld lines tend to occur in the thin annular portion, which may result in the manufacture of a battery case lid with a defective diaphragm or production loss.

The present invention provides a method for forming a sealed liquid spout in a ready-to-use storage battery case lid.

When integrally molding the outer periphery of the diaphragm with a diaphragm having the shape of an annular relatively thin part, the annular thick part provided on at least one of the opposing surfaces of the mold for molding the diaphragm is molded. A thick molding gate is provided on a part of the annular protrusion for communicating with the molded part of the central part and the liquid port cylinder, and the vf feature is that it is integrally molded.
