Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a battery case in which a plurality of batteries are packed to form a battery package, and more particularly to a battery case that is easily disassembled for recycling.
[0002]
[Prior art]
The conventional battery case has a structure in which a case lid is welded to a case body, and means for facilitating disassembly is not taken. Therefore, it is troublesome to take out the battery for recycling. That is, the battery case is cut or crushed with a blade, but when the battery case is cut with a blade, the battery may be short-circuited, which is dangerous and takes time.
[0003]
When the battery package is crushed together with the battery case, it takes time to separate the battery package. In addition, the cell battery may be deformed during the pulverization, causing a short circuit inside, and there is a risk of explosion.
[0004]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and an object of the present invention is to provide a battery case in which a battery package can be easily disassembled for sorting.
[0005]
[Means for Solving the Problems]
In the battery case of the present invention, an elongated hole and grooves extending from both ends of the hole are formed in a plate-like member constituting the battery case that exposes a terminal wired to the battery from the hole.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. FIG. 1A is a perspective view showing a battery case according to an embodiment of the present invention, and FIG. 1B is a sectional view showing the battery case. The case body 1 shown in the figure has a rectangular container shape, and houses batteries 4, 4,.... The cover 2 has a rectangular plate shape, and has holes for exposing the terminals 3.
[0007]
The case lid 2 is fitted to the case body 1 so that the terminals 3, 3 wired to the batteries 4, 4,... Are exposed from the holes of the lid 2, and are welded at the edge 1a. The lid 2 is provided with a U-shaped hole 2a and a groove 2b connected thereto.
[0008]
The disassembly method of the battery package will be described with reference to FIG. First, as shown in FIG. 2A, a driver is inserted into the U-shaped hole 2a, and a portion surrounded by the U-shaped hole 2a is pushed up. Next, a part of the lid 2 is opened by pulling a portion surrounded by the U-shaped hole 2a and tearing the groove 2b as shown in FIG. 2B. Next, as shown in FIG. 2C, the other part of the lid 2 is opened. Since the lid 2 is widely opened in this manner, the batteries 4, 4,... Can be easily taken out.
[0009]
FIG. 3 shows another embodiment of the present invention. In this example, an arc-shaped groove 2c is provided in the case lid 2, and grooves 2b are provided at both ends thereof. Other configurations are the same as those shown in FIG. If the internal battery can be taken out by tearing the groove 2b of the case lid 2 in this way, the elongated holes and grooves can have any shape.
[0010]
Although the embodiment is configured as described above, the invention is not limited to this. For example, the groove may be provided outside the lid instead of inside. Further, the shape of the groove is not limited to the V shape, but may be any shape as long as it is concave.
[0011]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to the battery case of this invention, a battery can be easily taken out from a battery package, and it is advantageous at the point of determining the recycling company.
[0012]
In addition, since the battery package can be easily disassembled, sorting and disposal is widely performed.
