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 in ready-to-use storage batteries, which have charged electrode plates and can be used immediately by simply injecting electrolyte into the storage battery when used without injecting electrolyte, have been developed. 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 Publication No. 171971/1987 discloses an electrolyte container for a storage battery, which has 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 is a container 1 made of acid-resistant synthetic resin having a liquid injection port 3 and an air port 4, and a thin film portion 5 is formed at the tip of the liquid injection port 3 and air port 4, and the thin film is formed on the upper part. The portion 5 is provided with a pair of protrusions 7 that can be opened, and
Plate 6 with a pair of protective caps 8 at the bottom
Protective caps 8 are fitted around the outer peripheries of the liquid injection port 3 and the air port 4, respectively, and a liquid injection pipe 10 that can be inserted into the liquid injection port 3 is held between the plate 6 and the container 1. This is an electrolyte container for a storage battery.

Embodiment An embodiment of the present invention will be described in detail based on the drawings. FIG. 1 is a front view of an electrolyte container for a storage battery according to the present invention. The electrolyte container 1 is made of acid-resistant synthetic resin (for example, polyolefin synthetic resin), and has one ready-to-use storage battery (not shown) inside. Contains an electrolyte solution. The upper surface of the container 1 is formed into a convex shape, and a convex portion 2 is provided. Further, the upper surface of both sides of the convex portion 2 is provided with a liquid injection port 3 and an air port 4.

A thin film portion 5 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 liquid injection port 3 and the air port 4 are sealed by the thin film portion 5.

Reference numeral 6 designates a plate having a protrusion 7 on the upper part of which the thin film part 5 can be unsealed, and a pair of protective caps 8 on the lower part that can be fitted around the outer circumferences of the liquid injection port 3 and the air port 4; The protective caps 8 protect the thin film portions 5, respectively. Note that the protrusion 7
The interval corresponds to the interval between the liquid injection port 3 and the air port 4.

Further, a recess 9 is provided on the upper surface of the convex portion 2, and a liquid injection pipe 10 made of acid-resistant synthetic resin is inserted into the recess 9. It is surrounded by a pair of projecting walls 11 provided at the bottom.

A handle recess 12 is formed on the side surface of the electrolyte container 1, 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. 2, the plate 6 is separated from the container 1 to expose the liquid injection port 3 and the air port 4, and the liquid injection pipe 1
Extract 0.

Subsequently, as shown in FIG. 3, the plate 6 is turned upside down, and the projections 7 are inserted into the upper portions of the liquid injection port 3 and the air port 4, and the thin film portion 5 is broken by pressing down.

Thereafter, as shown in FIG. 4, the liquid injection pipe 10 is inserted into the liquid injection port 3, and the liquid is injected into the liquid injection port of a storage battery (not shown).

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) Thin film portions 5 are fixed to the tips of the liquid injection port 3 and air port 4 of the electrolyte container 1, and a plate with protrusions 7 is fitted to the container 1, so that it cannot be used with scissors, nippers, etc. The seal can be opened by simply tearing the thin film part 5 with the projection part 7 without using any tools, 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, since the thin film portion 5 is covered by the protective cap 8 of the plate 6, there is no fear that the thin film portion 5 will be torn during storage or transportation of the electrolyte container 1.

(3) Since the liquid injection pipe 10 is attached, liquid injection work can be easily performed.

(4) By providing a pair of protrusions 7, the liquid injection port 3
and the thin film portion 5 of the air port 4 can be torn at the same time.
