Claims

[Scope of Claim for Utility Model Registration] 1. A plurality of liquid injection holes are arranged on the top wall of the battery container lid, and a liquid injection tube is placed in each liquid injection hole between the liquid injection hole and the peripheral wall of the liquid injection hole, and an electrolytic solution is placed in the top wall of the battery container lid. An annular gap is provided in the vertical direction into which the neck of the container is inserted, so that when the neck of the electrolyte container is fitted to the outer periphery of the liquid injection cylinder, the seal face material of the neck is pierced and torn. A liquid injection device for a liquid injection type storage battery according to the present invention, wherein at least a part of an inner circumferential wall surface of an upper end portion of the liquid injection barrel is formed as a hydrophilic treated surface portion. 2. The injection tube is made of synthetic resin, and the hydrophilic treated surface is formed by attaching a hydrophilic material to the surface to be treated, or by surface oxidation by flame,
2. The liquid injection device for a liquid injection type storage battery according to claim 1, wherein the liquid injection device is formed by making the treated surface itself hydrophilic by roughening the surface by polishing or the like. 3. The hydrophilic treated surface portion is formed by forming a portion of the inner circumferential wall surface near the upper end opening surface of the liquid injection barrel into a longitudinal hydrophilic treated surface portion that extends halfway down from the upper end of the tube or over the entire length to the lower end. A liquid injection device for a liquid injection type storage battery according to claim 1 or 2.
