Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electrolyte container for injecting electrolyte into a ready-to-use storage battery.

Conventional technology and its problems Conventionally, electrolyte containers used for storage batteries that have charged plates and can be used immediately by simply injecting electrolyte into the storage battery without injecting electrolyte, that is, ready-to-use storage batteries. For this purpose, there is a liquid injection port on the top surface for attaching a liquid injection rubber cap with the end closed.
Japanese Utility Model Application No. 55-171971 discloses an electrolytic solution container for a storage battery having a concave bottom surface with an air exchange hole whose end that does not protrude from the bottom is closed.

However, in this electrolyte container, when injecting liquid, the rubber cap for liquid injection and the tip of the air displacement hole must be cut using a tool such as scissors or nippers, which is time-consuming.

Additionally, there is a risk of liquid leaking from between the liquid injection port and the rubber cap.

Purpose of the invention The present invention solves the above-mentioned drawbacks, and provides an electrolyte container for storage batteries that can be easily and reliably filled without using tools such as scissors or nippers, and is free from the risk of leakage. It is something.

Structure of the invention The present invention provides an electrolytic solution container 1 for a storage battery, which has a container main body 1a, a protection member 6, and a liquid injection pipe 11.
The container body 1a is made of acid-resistant synthetic resin and has a liquid injection port 3 and an air port 4 on the top surface, and a thin film portion 5 is formed at the tip of the liquid injection port 3 and air port 4. The protective member 6 has a connecting member 6a, a protruding liquid injection nozzle 7, and a pair of protective caps 8a and 8b, and the connecting member 6a has a rod shape, The pair of protective caps 8a and 8b are integrally connected, and the liquid injection nozzle 7 has a protruding tip, is installed on the upper surface of the protective cap 8a, and communicates with the inside of the protective cap 8a. The protective cap 8a fits on the outer periphery of the liquid injection port 3, and the protective cap 8b fits on the outer periphery of the air port 4 and communicates with the inside of the air port 4. Air hole 9
The liquid injection pipe 11 is capable of fitting into the liquid injection nozzle 7 and is held between the upper surface of the container body 1a and the connecting member 6a. It is something.

Embodiment An embodiment of the present invention will be described in detail based on the drawings. Figure 1 is a perspective view of the electrolyte container for storage batteries of the present invention, Figure 2
The figure is a perspective view of each part of the electrolyte container 1. The main body 1a of the electrolyte container 1 is made of acid-resistant synthetic resin (for example, polyolefin synthetic resin), and there is a ready-to-use storage battery (not shown) 1 inside. Individual electrolyte solution is sealed. The upper surface of the container body 1a is formed into a convex shape, and a convex portion 2 is provided. In addition, a liquid injection port 3 and an air port 4 are provided on the upper surface of both sides of the convex portion 2.
It is equipped with

A thin film portion 5 made of an aluminum seal whose back surface is coated with an acid-resistant synthetic resin is fixed to the tips of the liquid injection port 3 and the air port 4, and the thin film portion 5 seals the liquid injection port 3 and the air port 4. ing.

6 is provided with a protruding liquid injection nozzle 7 on the upper part of which the thin film part 5 can be unsealed, a protective cap 8a that can be fitted around the outer periphery of the liquid injection port 3, and an air hole 9 that can be fitted onto the outer periphery of the air port 4. This is a protective member in which a possible protective cap 8b is integrally connected by a rod-shaped connecting member 6a, and the protective caps 8a, 8b of the protective member 6 are
are fitted into the liquid injection port 3 and air port 4, respectively.
The thin film portion 5 is protected. Note that the nozzle 7 communicates with the inside of the protective cap 8a.

Further, a recess 10 is provided on the upper surface of the protrusion 2, and a liquid injection pipe 11 made of acid-resistant synthetic resin is fitted into the recess 10, and the connecting member 6a of the protection member 6 and the main body 1a are connected to each other. is held between.

A handle recess 12 is formed on the side surface of the main body 1a, and is used as a handle during liquid injection and transportation.

Next, a method of using the electrolyte container for a storage battery according to the present invention will be explained. In order to start using a ready-to-use storage battery, it is necessary to inject an electrolyte into the battery, and the electrolyte container 1 shown in FIG. 1 is used. First, as shown in FIG.
Then take out the liquid injection pipe 11.

Subsequently, as shown in FIG. 3, the protective member 6 is turned upside down, and the protruding liquid injection nozzles 7 are inserted into the upper parts of the liquid injection port 3 and the air port 4, respectively, and are pressed down to break the thin film portion 5.

Thereafter, as shown in FIG. 4, the protective caps 8a, 8b of the protective member 6 are fitted into the original positions of the container body 1a, and the liquid injection pipe 11 is fitted to the protruding liquid injection nozzle 7, and the storage battery (not shown) is fitted. Pour the liquid into the liquid injection port.

Effects of the invention Since the invention has the structure as described in the claims for its utility model registration, it has the following effects.

(1) The thin film portion 5 is fixed to the tips of the liquid injection port 3 and the air port 4 of the container body 1a, and the protective member 6 provided with the protruding liquid injection nozzle 7 is fitted into the container body 1a. The seal can be opened simply by tearing the thin film portion 5 with the protruding liquid injection nozzle 7 without using tools such as scissors or nippers, making the liquid injection work easier.

(2) The liquid injection port 3 and the air port 4 are completely sealed by the thin film portion 5, so there is no risk of liquid leakage. Further, the thin film portion 5 serves as the protective cap 8a, 8 of the protective member 6.
b, there is no risk that the thin film portion 5 will be torn during storage or transportation of the electrolyte container 1.

(3) Since the liquid injection pipe 11 is fitted into the liquid injection nozzle 7 to inject the liquid, the electrolyte can be easily injected without scattering it outside the storage battery.
