Abstract

PROBLEM TO BE SOLVED: To prepare a laminated pressure-sensitive adhesive tape suited in carrying it in a pocket, a bag, and the like, timesaving in cutting it each time and, in addition, easy to peel off one by one since its end portions are in a non-tacky state, and furthermore, without hindering its application to mirror- smooth surfaces with reduced unevenness. SOLUTION: This laminated pressure-sensitive adhesive tape can be obtained by laminating a plurality of cut tapes 1 having been cut to a predetermined size and each having a pressure-sensitive adhesive layer 2 on its back surface disjointedly at least one end portion of the cut tape and covering the lowest layer of the laminated cut tapes with a release sheet 3. As the method of disjointing the end portion of the laminated cut tapes, a method of applying a covering paper 4 to the end portion of each of the laminated cut tapes, a method of not providing the end portion with the pressure-sensitive adhesive layer, a method of folding the end portion, and the like, can be thought. Also, the lateral ends of the portions of the laminated cut tapes in a disjointed state can sometimes be slanted so as to more project out at the ends of the end portions of upper layers of the laminated cut tapes.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated adhesive tape, and more particularly, to a laminated adhesive tape which is compact and portable.

[0002]

2. Description of the Related Art Various adhesive tapes are widely used for various purposes such as gum tape, packing, dust removal, and work. Each of them is roll-wound, and the required amount is drawn out, cut with hands or scissors, and cut with a saw-tooth cutter when used.

[0003]

As described above, all of the conventional adhesive tapes are roll-wound, and a required amount of the tape is drawn and cut for use. Because of this, it is difficult to peel off and it is inconvenient to carry.

Accordingly, the present invention is suitable for being carried in a pocket or a bag, so that the labor for cutting each time can be omitted, and since the end portions are in a non-adhesive state, it is easy to peel off a single sheet. It is still another object of the present invention to provide a laminated adhesive tape which does not hinder use on a mirror-finished surface with little unevenness.

[0005]

According to the present invention, a plurality of cut tapes each having a pressure-sensitive adhesive layer on the back surface cut to a predetermined size are laminated with at least one end thereof being in a state of being separated, and the lowermost cut tape is formed. The above-mentioned problem has been solved by a laminated pressure-sensitive adhesive tape provided with a release sheet. Examples of a method of making the end portions loose include a method of attaching a paper to be wrapped, a method of not providing an adhesive layer, and a method of folding the end portions. The end-side end face in the loose state may be formed as a slope protruding outward as far as the upper layer cut tape.

[0006] In addition, as for use on a surface having little unevenness such as a table surface, a floor surface, and a glass surface, the cut tape of the uppermost layer to the cut tape of the lowermost layer or the release sheet is used. Up to this point, a structure in which a through-hole is appropriately formed and a structure in which a non-adhesive portion is provided throughout the entire surface of the adhesive layer are proposed.

[0007]

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of an embodiment of the present invention, in which an adhesive layer 2 is provided on the entire back surface of a tape material similar to a conventional tape material, and a plurality of cut tapes 1 cut to a predetermined size are laminated. Then, a release sheet 3 is fixed to the adhesive layer 2 of the lowermost cut tape 1.

At the end of the adhesive layer 2 of each cut tape 1,
The wrapping paper 4 for removing the adhesiveness of the portion is attached (see FIG. 2A). Therefore, the end of the side where the cover paper 4 is attached becomes loose without sticking, and it is easy to hold only the uppermost cut tape 1 when peeling off the cut tape 1. Does not peel off together. This loose state may be applied not only to one end but also to both ends (the same applies to the following embodiments).

In the example shown in FIG. 2B, the non-adhesive portion 5 without the adhesive layer 2 is used instead of attaching the wrapping paper 4, as shown in FIG. 2C. In the example, the end of each cut tape 1 is folded back and adhered. In these cases, as in the case described above, the end portions are in a loose state, and the cut tape 1 can be easily peeled to one sheet.

Although the illustrated cut tape 1 is rectangular, the cut tape 1 is not limited to this, and may be circular, elliptical, star-shaped, or any other shape. Also in the case of these various shapes, the wrapping paper 4 is attached to the end in the same manner as described above, or
The non-adhesive part 5 is provided or the folded part 6 is provided.

Further, it is not always necessary to make it thick like the one shown in FIG. 1, but it is possible to make it several pieces thin so that it can be easily put in a regular purse or a wallet. On the cut tape 1, graphics, characters, and the like may be printed or a seal may be attached as necessary. Printing may be performed only for the uppermost cut tape 1 or may be performed for each cut tape 1.

In the example shown in FIG. 3, the end-side end face 8 which has been loosened by the above-described method is formed as a slope which projects outward as much as the cut tape 1 in the upper layer. in this case,
Since the end of the cut tape 1 of the uppermost layer to be peeled overhangs slightly forward from the end of the cut tape 1 therebelow, the operation of peeling one by one with a finger is easier and more reliable. Can be done.

Reference numeral 7 in FIG. 1 denotes a thread-like material interposed between the adhesive layer 2 of the lowermost cut tape 1 and the release sheet 3 as required. In order to facilitate peeling in That is, by pulling it, the end of the peeling sheet 3 is raised, and the gripping becomes easy. When the peeling sheet 3 extends to the end on the loose side, the thread 7 is not necessary.

The embodiment shown in FIG. 4 is used for a mirror-finished surface such as a table, a desk, a flooring such as a flooring or a pie tile, a glass, a leather product, a resin sheet, etc. It is suitable. In other words, the cut tape 1 strongly adheres to the surface with less unevenness, and although hair and dust are removed, it is difficult to separate the cut tape 1 from the surface. In some cases, the surface of the surface may be torn or peeled off.

In view of such a point, the present inventor considered that the adhesive strength was reduced to such an extent that the original adhesive performance of the cut tape 1 was not impaired, and as shown in FIG. A means has been devised in which a through hole 9 is appropriately formed from the tape 1 to the lowermost cut tape 1 or the peeling sheet 3. Thereby, the adhesive strength of the cut tape 1 is, for example, 20 to 3 depending on the size and the number of the through holes 9.
Although it is reduced by 0%, it hardly affects the adhesion of hair, dust, and the like.

The same effect can be obtained by appropriately providing the non-adhesive portion 10 without fixing the adhesive over the entire surface of the adhesive layer 2. FIG. 5A shows an example in which the non-adhesive portions 10 are provided in a grid pattern.
The one shown in (B) is a non-adhesive part 1 having a circular or other appropriate shape.
A large number of 0s are provided in a zigzag or the like. Of course, the method of providing the non-adhesive portion 10 is not limited to these.

[0017]

Since the present invention is as described above, it is easy to peel off one sheet at a time even in a laminated state, and it can be used easily without the trouble of cutting to a desired length. Suitable for carrying in pockets, bags, etc., used to remove hair and dust from clothes and car seats, to seal packaging, and for various other uses. There is an effect that can be done.

Further, in the inventions according to claims 7 and 8, in addition to the above-mentioned effects, even when used on a mirror-like surface such as a desk, a table or a floor, the cut tape itself can be used. This has the effect of facilitating separation from the surface.
