Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bulk injection type electrolyte solution enclosure container for storage batteries.

[Conventional technology]

Conventionally, a single cylindrical container filled with a predetermined amount of electrolyte and sealed with a sealing member is used as a bulk injection type electrolyte enclosure container for storage batteries. Correspondingly, a batch-filling type electrolyte-filled container for a storage battery is known, in which a plurality of electrolyte-filled containers are integrally connected to each other by a connecting member. Immediately before using the ready-to-use storage battery, the container is constructed by fitting the liquid injection ports of the plurality of cell chambers of the storage battery with the corresponding liquid injection tubes of the single container, and inserting the liquid injection tubes into the container. It is used to perform bulk injection of electrolyte through a piercing opening.

[The problem that the idea attempts to solve]

In the conventional containers described above, when liquid is poured all at once, liquid injection into the single container may be blocked due to the effects of generated air bubbles, surface tension of the sulfuric acid electrolyte, atmospheric pressure, etc. In this case, it was common practice to release the clogged container by tapping the container in which the liquid had stopped pouring. However, by tapping, the external force is transmitted through the connecting member to the container around which liquid is being poured normally, and as a result, the pressure of the liquid being poured becomes unbalanced.
On the contrary, the liquid injection may be blocked. Furthermore, if the tapping operation is too weak, sufficient pressure necessary to release the liquid filling may not be generated within the container itself. If the container is struck too strongly, the predetermined heat distribution throughout the container may be disrupted, and the above-mentioned adverse effects may occur inadvertently.

[Means to solve the problem]

The present invention solves the above-mentioned conventional drawbacks and provides a bulk injection type electrolyte-filled container for storage batteries that can smoothly release the blocking of liquid injection. In a bulk injection type electrolyte-filled container for a storage battery, which is formed by integrally connecting a plurality of single containers sealed with a sealing member to each other by a connecting member, at least a part of the circumferential side wall of each single container is formed into a bellows shape. It consists of

[Function] After all the containers of the present invention are fitted into the liquid injection ports of the corresponding cells of the storage battery and opened, when the liquid injection of the containers stops, push or If pressure is applied from the side surface of the bellows wall, the container itself will be easily compressed and deformed, and the resulting internal pressure will release the liquid blockage, and since the pressure is applied, the external force will not be transmitted to other single containers.
In this case, if a free space is provided between adjacent containers, the containers can be easily pressed from the upper end, and the containers can be compressed and deformed to a large extent.

〔Example〕

Embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows one example of implementation of the invention. 1 is 6
The electrolyte-filled container 1 of the present invention is used for bulk injection into each cell chamber of a ready-to-use storage battery consisting of cells. Six cylindrical individual containers 2 are integrally connected to each other by a connecting member 3. Each container unit 2 is composed of a large-diameter container main body 2a and a small-diameter liquid injection cylinder 2b whose tip extends and projects and can be inserted into a liquid injection port of a cell chamber of a storage battery. The mouth of the liquid injection cylinder 2b is sealed by heat-sealing with an enclosure member 1a made of aluminum foil laminated with a synthetic resin film, for example.
I'm there. Generally, these six individual containers 2 and the connecting member 3 are made of synthetic resin such as polyethylene and are integrally molded by blow molding, and are transparent or translucent and have a wall thickness of about 1 mm. Although not shown, the liquid level of the filled electrolyte is
Can be seen from the outside.

The above configuration is not particularly different from a conventional enclosure container. According to the present invention, in such a sealed container 1, at least a part of the circumferential side wall of each electrolyte sealed container 2 is formed into a bellows 4, and in the embodiment shown in FIG. The upper part of the single container 2 was formed into a bellows 4. Due to this bellows formation, when the upper end surface of the container 2 is pressed from above, the container 2 can be compressed, and an internal force can be generated to push the electrolyte. In this case, the connecting member 3 is not used to connect the adjacent single containers 2 over the entire length of the container body 2a, in particular, the upper part lacks the connecting member 3, and the adjacent single containers 2,
By providing a free space 5 between the two containers, the upper part of each container unit 2, 2 having the bellows wall 4 is
When separated from each other, each single container 2 is extremely easily compressed by the above-mentioned pressing force, and a larger internal pressure is generated, so it is advantageous that the single containers 2 can be compressed relatively largely with a relatively small pressing force. . The pressure can also be applied by pinching and pressing a portion of the bellows wall 4 from the side with fingers, whereby the container 2 can be compressed and deformed at that portion, and a large pressure can be generated inside. Incidentally, if desired, a bellows 4 may be formed at the lower part thereof as shown in the figure, and furthermore, a bellows 5 may be formed over the entire length of the peripheral side wall of the container body 2a of the container unit 2. Reference numeral 6 indicates ribs integral with the outer wall surface of the container unit 2 at both outer ends, which strengthen and protect the outer wall surface. In order to use the container 1 of the present invention constructed in this way for bulk injection into a ready-to-use storage battery consisting of 6 cells suitable for this purpose, it is necessary to prepare the corresponding liquid in each injection tube 2b in the usual manner. It fits into the inlet of the cell chamber. At this time, the sealing member 1a is pierced by the tip of the cylindrical wall of each liquid injection port, and liquid injection is automatically started. Inside,
Liquid clogging may occur. In this way, if liquid injection is blocked for some reason, by pressing the upper end surface of the container 2 that is clogged with the liquid with your finger as shown by the arrow, the bellows 5 will form and easily remove the liquid. The container unit 2 is compressed, thus creating pressure inside and pushing the clogged liquid, thereby unblocking the liquid and starting or resuming pouring. Since the pressurizing force is a pressing force, the liquid clogged container itself 2
However, since it does not apply to other individual containers 2, it does not interfere with the operation of the individual containers 2 that are normally injecting liquid. FIG. 3 shows a modified example, in which the connecting member 3 is configured to extend to the upper end of each individual container 2, and has bellows on the upper and lower parts of the peripheral side wall of the container body 2 of each individual container 2. 5,5 is shown. Therefore, either container 2
If a liquid clog occurs in the container 2, it can be easily compressed by squeezing the portion formed in the bellows 5 from the front and rear sides of the container 2, thereby generating internal pressure and restarting liquid injection. I can do it.
Depending on the situation of liquid clogging, either the upper or lower bellows walls 5, 5 are pressed as desired. However, the bellows 5 need not necessarily be provided at the upper and lower portions, and may be provided only at either one, or may be provided over the entire length of the container body 2a.

Incidentally, in the case of a single conventional container that lacks the formation of bellows, even if pressure is applied from the top or from the side,
The container hardly deforms, and no internal pressure is generated to clear the clog.

[Effect of idea]

As described above, according to the present invention, in a bulk filling type enclosure for a storage battery, which is composed of a single container filled with a plurality of electrolytes connected to each other by a connecting member and sealed with a sealing member, each container is Since a bellows is provided on the peripheral side wall of the electrolyte, the electrolyte-filled container can be compressed by pressing. Therefore, by pressing a clogged container, it is possible to release the clogged liquid and perform liquid injection. When a part of the connecting member that connects single containers is missing, leaving a free space between the containers, and a bellows is formed on the side of the single container at a position corresponding to the space, pressing from above is required. It has the advantage of being able to easily eliminate compression due to
