Abstract

PURPOSE:To prevent the contact failure and generation of rust on a positive electrode by coating one side of band-shaped tape with adhesives, bonding a band-shaped film on the base after bonding it along the central part of an adhesive surface, and forming a cut to remove sealed tape. CONSTITUTION:One side of a band-shaped tape mainframe 1 consisting of slick paper, coated paper or polyethylene film, etc. is coated with adhesives 2 and band-shaped film 3 such as PP, PVC, and PE is bonded on almost the central part of the tape mainframe. The adhesive surface of the tape mainframe is bonded on band-shaped ground paper 4. Then, a strip cut 6 is formed on the upper face of the tape mainframe in the width direction so as to remove sealing tape 5. In this case, the depth of the cut reaches the intermediate section of the ground paper 4 and the sealed tape 5 has a shoulder section 51 on its external surface. The sealing tape 5 thus obtained permits the adhesive surface to be bonded on a dry cell 7 and film 3 to be located on a positive electrode terminal. As a result, contact failure can be removed without making the adhesives adhere to the terminal.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a dry cell sealing tape used for sealing the anode terminal of a dry cell.

Conventionally, the anode terminal of a dry cell battery is sealed with sealing tape to indicate that the dry cell is unused and at the same time to protect the anode terminal.

However, if the anode terminal is sealed with sealing tape in this way, the adhesive of the tape may adhere to the terminal and cause poor contact, or the moisture contained in the tape may cause rust on the terminal, or the sealing tape may not be used properly. There were problems such as it was troublesome to separate.

This invention was made in view of the circumstances in the article.

To provide a method for producing a sealing tape for a dry battery, which can surely eliminate poor contact and rust of an anode terminal and can be easily separated after sealing.

An embodiment of this invention will be described below.

First, a strip-shaped tape body made of straw such as high-quality paper, art paper, or polyfilm is prepared, and an adhesive is applied to one side of the tape body. Next, a width of 10 to 15 mm is applied along the approximate center of the tape body to which the adhesive has been applied.

A strip-shaped film of PP, PVC, PG, etc. with a thickness of 20 to 30 μm is adhered. Then, the adhesive surface of the tape body to which the converted film is adhered is adhered to a band-shaped base, for example, a mount F. This state is shown in Figures @1 and 2. Here, l in Figure 1 is the tape body.

2 is an adhesive, 3 is a film, and 4 is a mount.

Next, as shown in FIG. 1, a strip-shaped cut 6 is formed in the width direction of the upper surface of the tape main body l, so that the sealing tape 5 can be peeled off. Such a sealing tape 5 has a tape main body l.
Many are formed along the

In this case, the depth of the cut 6 is as shown in FIG.
Make sure it reaches halfway. Furthermore, as shown in FIG. 1, the sealing tape 5 has a constricted portion 51 at its periphery.

The sealing tape 5 is peeled off from such a deaf person as necessary. In this case, the depth of the cut 6 in the sealing tape 5 reaches halfway through the mount 4, so that the film 3 is positioned at the center of the tape body 1, as shown in Figure f83.

The sealing tape 5 thus obtained is adhered with its adhesive surface to the anode terminal side of the dry battery 7 as shown in FIG. 4. The sealing tape 5 is made so that the film 3 portion is located on the anode terminal.

Therefore, according to the sealing tape obtained by this method, when the anode terminal side of the dry battery is sealed, the film part of the tape is located on the anode terminal, so the adhesive does not adhere to the terminal and there is no possibility of poor contact between the terminals. The cause of this can be removed. Furthermore, even if the tape body contains some moisture, the influence on the anode terminal can be removed by the film portion, thereby eliminating inconveniences such as rust on the terminal. It can be redeemed.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented with appropriate modifications without changing the gist.

As described above, according to the present invention, it is possible to provide a method for manufacturing a sealing tape for a dry battery, which can reliably eliminate poor contact and rust of the anode terminal, and also allows easy separation after sealing.
