ている。(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. First
The figure is a partially cutaway front view of a storage battery electrolyte container sealed by the method of the present invention. In the figure, reference numeral 1 denotes an electrolytic solution container made of a polyethylene-based synthetic resin, which is configured by connecting six identical members 1a. Each of the above-mentioned same-shaped members 1a is composed of a body part 2 and a cylindrical liquid injection cylinder 3 integrally formed at the tip thereof. The interior of each of the same-shaped members 1a is hollow, and is filled with an electrolytic solution. In each of the same-shaped members 1a filled with the electrolytic solution, the opening at the tip of the liquid injection tube 3 is sealed by the thin film 4. The thin film 4 is configured by stacking an aluminum sheet and a soft polyethylene sheet.

になる。Next, a method of sealing the opening at the tip of the injection cylinder 3 with the thin film 4,
That is, the method for sealing the electrolyte container 1 will be described. First, after the same-shaped member 1a is filled with the electrolytic solution 5, the thin film 4 is brought into contact with the tip of the liquid injection tube 3 so as to close the opening. At this time, the thin film 4 makes the polyethylene sheet side abut on the tip of the liquid injection tube 3. Then, the thin film 4 is heated from the aluminum sheet side while applying a pressure of 0.3 kg / cm 2 or more, and is welded to the tip of the liquid injection tube 3.
After welding, the applied pressure is released. As a result, the inside of the same-shaped member 1a is in a pressurized state, and the thin film 4 projects outward.

m 2 , 0.3 kg / cm 2 , each of 30 electrolyte containers was sealed, pierced into the injection port of the storage battery, and the result of investigating whether or not the electrolyte automatically flowed into the storage battery at the start of injection was determined. It is shown.
上記調査結果から明らかなように、加える圧力が0.3k
g/cm2以上であれば、自動的に注入できる。 As is clear from the above survey results, the applied pressure is 0.3k
If it is more than g / cm2, it can be injected automatically.

ができる。(Effect of the Invention) As described above, according to the sealing method of the present invention, the thin film 4 formed by laminating a polyethylene sheet and an aluminum sheet is
The polyethylene sheet side was brought into contact with the tip of the injection cylinder 3 (sealing port), and heat was welded to the tip of the injection cylinder 3 while applying a pressure of 0.3 kg / cm 2 or more from the aluminum sheet side. After the sealing, the inside of the electrolytic solution container 1 can be pressurized. Therefore, when the thin film 4 is broken by the protrusion of the liquid injection portion of the storage battery, the electrolyte rushes out and flows into the storage battery, and the electrolyte can be automatically and smoothly injected into the storage battery. Also, the injection time can be shortened.
