【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows the configuration of the double-sided tape of the present invention. FIG. 2 shows the details of the main part of the double-sided tape of the present invention. FIG. 3 shows the usage status. The double-sided tape 1 of the present invention is wound around a core P with a release paper 3 adhered to the surface of a long double-sided adhesive sheet 2 having an adhesive layer formed on the front and back surfaces. The sheet 2 is provided with a cut portion 2a in the short direction at a predetermined interval in the long direction, and the release paper 3 is provided with a perforated portion 3a at the same position as the cut portion 2a of the double-sided adhesive sheet 2. ing.

The double-sided pressure-sensitive adhesive sheet 2 has a pressure-sensitive adhesive layer formed by applying an adhesive to the front and back surfaces of a sheet-shaped member, and the cut portion 2a is completely cut in advance in the short direction across the front and back surfaces. You. If the cut portions 2a are formed at intervals of, for example, 1 cm in the longitudinal direction, the trouble of measuring the length one by one using a scale can be omitted. Of course, the interval in the longitudinal direction may be set to, for example, an interval of 0.5 cm as appropriate.

On the other hand, the release paper 3 is coated with, for example, wax on the back side, that is, the contact surface with the surface of the double-sided pressure-sensitive adhesive sheet 2, so that the double-sided pressure-sensitive adhesive sheet 2 does not stick. , And can be easily peeled off. The release paper 3 has a cut portion 2 a on the double-sided adhesive sheet 2, whereas a perforated portion 3 a is formed at the same position, and the perforated portion 3 a is formed on the release paper 3. Is for the following reason.

That is, when the double-sided tape 1 is used, the double-sided adhesive sheet 2 attached to the back surface of the release paper 3 is pulled out by pulling out the release paper 3. If the release paper 3 as well as the release paper 3 is cut, it is difficult to pull out the double-sided pressure-sensitive adhesive sheet 2 at a time, for example, when trying to use a relatively long portion. For No. 3, a perforated portion 3a is provided.

The reason why the perforated portion 3a is provided on the release paper 3 is based on the following reason in addition to the above-mentioned reason. That is, when the double-sided pressure-sensitive adhesive sheet 2 is adhered to one of the adherends T1 and cut to the required length, and even the release paper 3 is cut, the double-sided pressure-sensitive adhesive sheet 2 is cut like the conventional double-sided tape. It becomes difficult to release the release paper 3 from the sheet 2.

Therefore, in order to improve the above problem, in the present invention, perforations 3a are provided at the same positions as the cut portions 2a of the double-sided adhesive sheet 2 with respect to the release paper 3. When the pressure-sensitive adhesive sheet 2 is cut at the cutting portion 2a, the release paper 3 is not cut, and is used at the perforated portion 3a after the release paper 3 is peeled off from the double-sided pressure-sensitive adhesive sheet 2 adhered to one adherend T1. The release paper 3 can be easily cut by a user without using scissors or a cutter, and the release paper 3 can be easily separated from the double-sided pressure-sensitive adhesive sheet 2.

Next, a procedure for using the double-sided tape 1 having the above configuration will be described. First, as shown in FIG. 3A, the required amount of the double-sided pressure-sensitive adhesive sheet 2 and the release paper 3 is pulled out, and one adherend T1 and the back surface of the double-sided pressure-sensitive adhesive sheet 2 are bonded. Then, as shown in FIG. 3 (b), the double-sided tape 1 itself is lifted upward and moved to the opposite side to the pull-out direction of the double-sided pressure-sensitive adhesive sheet 2 and the release paper 3, so that one of the adhered sheets is adhered. The double-sided pressure-sensitive adhesive sheet 2 stuck to the body T1 and the double-sided pressure-sensitive adhesive sheet 2 stuck to the release paper 3 side are cut by the cutting portion 2a.

Further, as shown in FIG. 3B, the release paper 3 is released from the double-sided pressure-sensitive adhesive sheet 2 adhered to one adherend T1. On one of the adherends T1, only the double-sided pressure-sensitive adhesive sheet 2 from which the release paper 3 has been peeled off is adhered. 3 has not yet been cut and remains. Then, as shown in FIG. 3 (c), the portion of the release paper 3 from which the double-sided adhesive sheet 2 has been peeled is cut along the perforated portion 3a, and thereafter, as shown in FIG. 3 (d). Then, the other adherend T2 is adhered to the surface of the double-sided pressure-sensitive adhesive sheet 2 adhered to one adherend T1.

As described above, according to the double-sided tape 1 of the present invention, only the required amount can be easily cut without using scissors or a cutter, and the double-sided adhesive sheet 2 and the release paper 3 Can be easily peeled off. The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the back surface of the release paper 3 is coated with wax in the above-described embodiment. Any material may be applied as long as it has the following, and the materials of the double-sided pressure-sensitive adhesive sheet 2 and the release paper 3 may be appropriately changed.
