Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of binding batteries for built-in charging.

[0002]

2. Description of the Related Art Recently, since many portable electric products have been developed, the demand for dry batteries to be used for them has increased, but disposable batteries have problems such as material protection and environmental protection. Therefore, it is not preferable, and it is preferable to use it for a long period of time as much as possible, and a rechargeable battery is required to meet this requirement.

Of these batteries, the capacity of one battery is often insufficient, and two or more batteries are used.

In addition, it is desirable to be as compact as possible because it is portable, and for example, when three batteries are required, these three batteries are arranged in a row and fixed, and then inserted into the product. Various developments have been made in order to make it possible to operate, but in each case, it is applied to electric equipment by a method of integrating single batteries and fixing with an adhesive, or a method of fixing with a cartridge case etc. It was built-in, and there was no effective and easy method.

When fixing with an adhesive or a hot-melting agent by the conventional fixing method, the batteries are arranged in a line in an orderly manner and adjacent batteries are joined together. However, the alignment of the batteries is disturbed at that time. However, the flatness is impaired, and it takes time to cure the adhesive.

[0006]

The present invention was developed in order to solve these problems. It is extremely easy to integrate a plurality of batteries, and the appearance is good and the accuracy is high.
The purpose is to provide a binding method that is easy to handle.

[0007]

The present invention will be described below. Formed into a cylinder capable of packaging a charging battery with a heat-shrinkable film, preparing a desired number of these cylinders, and adhesively bonding only those portions of these cylinders corresponding to the height of the battery to each other, In this method, batteries are inserted into these cylinders, respectively, and heat shrinks to bind the batteries.

Further, as each of the cylinders, both a tube formed by bonding and a seamless cylinder can be used.

When the adhesive is applied, it is preferable to previously apply an ink layer which does not have the adhesive to a portion where the adhesive should not be applied by using a printing machine.

[0010]

The present invention is the above-described method, which is the same as the conventional one in use, but has a very small dimensional error, good appearance, easy handling, and easy manufacture. , Can provide inexpensive and precise products.

The ink layer may be a transparent ink or a coloring ink as long as it has no adhesive.

Unlike the conventional packaging method, the binding method of the present application does not cause a space between the battery and the battery and the film, so that there is no breakage, and the film adheres to the entire circumference of each battery. Printed expressions such as displays and POS codes can be easily used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the drawings.

The heat-shrinkable film F is formed on the cylindrical body 1 capable of packaging the charging battery A, and the cylindrical bodies 1 ... Are prepared for a desired number of batteries A, and the portion corresponding to the height H of the batteries A is formed. Only h is adhered and joined to the adjacent tubular bodies, and no further portions are joined. Thereafter, the batteries A are attached to the tubular bodies 1 ...
.. Insertion, heating, and shrink-wrapping
Is a method of binding a plurality of batteries A, each of which is bent above and below each battery A.

As the tubular body 1, both a laminated tubular body 1a and a seamless tubular body 1b can be used.

Of course, it is also possible to use a plurality of films to manufacture one cylinder.

Further, in the above case, it is obvious that even if the length of the cylindrical body is contracted, the length longer than the height of the battery is an effective means for insulating both electrodes of the battery.

By doing so, when the batteries A ... Are put into these cylinders 1 ... and contracted, they contract at the same height as the cylinders, and then these cylinders 1 ...
Since the non-bonded portions C at both end portions are bent and contracted to the upper end portion and the bottom surface of each battery, the product can be packaged under a certain condition.

In the case of adhering the cylinders 1 and each other, first, using a printing machine, an ink layer D is first provided on a portion where the adhesive should not be attached to the film F in advance, that is, a non-bonding portion C, and this is attached to the cylinder. After being formed into a body, the required number of the cylinders 1 ... Of the built-in batteries A ... Are arranged side by side on the sealing machine, and the adhesive layer S is formed in an appropriate width along the fold line of the cylinders 1 ... This method is accurate, and the operation is performed in almost the same work procedure as the conventional seal adhering work, and the two cylinders 1 ...
-Is drawn out along the guide and the desired seal adhesion can be easily created accurately.

In this case, it is not necessary to provide an ink layer on all the cylinders 1, ...
In the case of three, the ink layer may be provided only on the central cylinder 1.

Other method For example, in the case of binding two batteries, it is possible to form a cylinder of a size that can accommodate two batteries and bind them together in the same way. Since there is a risk that the film will not be adhered to the space between the cylinders in the valley, the film may loosen and the package may fall off, so it cannot be said to be a reliable packaging form.

[0022]

The present invention has the above-mentioned structure, and when it is used, it is the same as the conventional one, but each battery is inserted into each corresponding cylinder. Therefore, since there is no space between the film and the film,
There is little risk of film breakage, dimensional error is extremely small, there is an advantage that time loss of assembly process can be reduced and defect occurrence loss can be reduced, good appearance, easy handling, easy manufacturing Therefore, it is possible to provide inexpensive and precise products.
