Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to adhesive tapes with a peel-off section and a tape support.

More specifically, in adhesive tapes, in order to facilitate peeling after adhesion processing, adhesive tapes with a peeling part have a gripping part or hook part for peeling consisting of a non-adhesive area at the end of the adhesive surface of the tape. In particular, when adhesive tapes need to be removed after being bonded to an object, the adhesive tape can be easily, quickly and completely removed from the object. The present invention relates to adhesive tapes with a peelable part that can be applied to the body, and a tape support that allows the adhesive tapes with a peelable member to be easily formed.

[Prior Art] Conventionally, adhesive tapes such as cellophane tape are adhered to an object to be adhered, and when the tape is removed after use, the object to be adhered and the tape are completely integrated. However, it is difficult to quickly and completely peel off the tape because the tape is stored away, and is therefore not necessarily suitable for practical use.

[Problems to be Solved by the Invention] In view of the above-mentioned points, an object of the present invention is to provide a method that allows adhesive tapes to be easily peeled off from an object to be adhered after an adhesive treatment is performed using the adhesive tapes. It is an object of the present invention to provide adhesive tapes specially provided with a peel-off part so that the peel-off part can be easily attached to the tape support. be.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present inventors have made extensive studies and found that by providing a non-adhesive area at the end of the tape on the adhesive surface, the adhesive It has been discovered that adhesive tapes can be easily and cleanly removed from objects to be adhered by preventing the entire body and the tape from becoming completely adhesive and integrated, leading to the present invention.

That is, the tapes of the present invention are adhesive tapes with a peelable part, which are characterized by having a non-adhesive area at the end of the tape adhesive surface.

In the adhesive tape with a peelable part of the present invention, preferably, the non-adhesive area is formed in a band-like or triangular shape, or alternatively, preferably, the non-adhesive area is formed by paper. It is characterized in that it is formed by bonding it together, or preferably, the paper is a removable adhesive paper, or it is characterized in that it is formed by pasting it together, or, alternatively, it is characterized in that the paper is a removable adhesive paper. The non-adhesive area is formed by bonding films together, or the non-adhesive area is formed by applying silicone resin. Alternatively, the non-adhesive area is formed by applying a fine powder material.

Further, the tape support of the present invention for easily forming the tape with a peelable portion according to the present invention is a tape support provided with a cutter for cutting the adhesive tape drawn out from the tape roll. , a tape support having a member located between the cutter and the tape-like roll that substantially eliminates the adhesive force of the adhesive surface of the adhesive tape to form a non-adhesive area. It is.

[Function] Hereinafter, the adhesive tapes with a peelable part and the tape support of the present invention will be explained in more detail using drawings and the like.

In the present invention, adhesive tapes include cellophane tape,
It is a general term for all tapes such as vinyl tape, gummed tape, double-sided tape, etc. that have an adhesive surface and are used for the purpose of bonding things together.

In the present invention, by providing a non-adhesive area at the end of these tapes that are cut and used for adhesion, when it becomes necessary to peel off the adhesive tape after use, it is possible to remove the tape from the object to be adhered. This makes it possible to quickly and easily peel off tapes.

In the present invention, a method for efficiently providing such a non-adhesive area at the end of each tape cut to an appropriate length is as follows:
For example, a tape support according to the present invention as shown in FIG. 1 may be used.

That is, a device 3 (in the example of FIG. 1, a non-adhesive area is formed at a position immediately before the cut portion 5 of an existing tape support 1, which is usually found as a support for cellophane tape 2, etc.) This can be achieved by providing a spring spring.

That is, the point is that in a tape support stand provided with a cutter 5 that can cut the adhesive tape drawn out from the tape-like roll (cellophane tape, etc.) 2 of the support 1, the cutter 5 and the tape-like roll are removed. A member 4 that substantially eliminates the adhesive force of the adhesive surface of the adhesive tape to form a non-adhesive area may be provided between the bodies 2.

The method of forming the non-adhesive area is not particularly limited, but one method may be, for example, pasting paper to the end of the adhesive surface of the adhesive tape. In this case, it is more preferable to use removable adhesive paper with weak adhesive strength as the paper.

That is, for example, as shown in FIG. By placing the paper strips 4 on the adhesive tape, each time the tape is cut, the paper strips 4 are peeled off from the bundle, and are sequentially moved to the end of the adhesive tape by contact pressure, thereby forming a non-adhesive area. In some cases, it may be preferable to use a film instead of paper as the small piece 4.

Another method is to use a roller coated with silicone or a roller coated with fine powder at the cutting part 5.
By providing the resin or powder just before the adhesive tape, it is possible to adopt a method of forming a non-adhesive area by transferring the resin or powder to the end of the adhesive tape.

In the case of the method using a small piece of paper 4, the small piece of paper 4 can be pasted to the end of the adhesive surface of the adhesive tape 8, as shown in FIG. , it becomes easy to remove the tape after use. The size of the small piece of paper may be any suitable length in the longitudinal direction of the tape. For example, a range of 1 anus to 10 mm is appropriate. Also, it is better to make the size of the small paper strip in the width direction wider than the tape width.
This is preferable because it makes the subsequent tape removal work easier. The same applies to the case where a film is used as the small piece.

It is preferable to use removable adhesive paper as the small paper strips because more efficient workability can be obtained.

That is, a stack of small pieces of removable adhesive paper of an appropriate size to be bonded to the non-adhesive area is placed on a pedestal and placed just in front of the cut portion of the tape support. At this time, a spring is provided under the base of the small paper piece so that the small paper piece comes into contact with the adhesive tape with an appropriate pressure and is transferred.

When adhering small pieces of removable adhesive paper to adhesive tapes,
The adhesive surface of the small piece may be the front side or the back side (the surface to which adhesive is applied). That is, in the former case, the adhesive force between the small piece and the tape is somewhat inferior, but it is preferable when writing notes on the small piece, and in the latter case, when the adhesive force between the small piece and the tape is to be made stronger. It is preferable for

With this method, each time the adhesive tape is cut to an appropriate length, the small piece of paper provided just before the cut part is adhered by the adhesive of the adhesive tape, resulting in a piece of paper as shown in Figure 2.
This results in an adhesive tape piece with a peelable part whose end is made of paper.

Furthermore, in this method, it is of course necessary that the adhesive strength of the removable adhesive paper is lower than that of the adhesive tape.

Still another method is to apply silicone resin or fine powder to the end of the adhesive tape, as shown in FIGS. 3 and 4. In the former method, for example, as shown in FIG. 3, a silicone coating roll is provided on the tape support just before the tape cutting part, and the silicone resin 6 is applied to the end of the adhesive tape 8 by the coating roll at the time of tape cutting. or the fourth method
As shown in the figure, instead of silicone resin, fine powder 7 (for example, celestial pollen "Sickarol" (manufactured by Wako Yakushima)) is used.
Similarly, it may be applied to the end of the adhesive tape 8 using a coating roll.

Adhesive tapes with a peel-off part of the present invention can be quickly and easily removed from an object to be adhered after use without staining the object with the adhesive tape.

The shape of the non-adhesive area is not particularly limited, but
Those having a substantially band-like shape or substantially triangular shapes can be preferably used. When a triangular shape is used, it can be provided on one or both sides of the tape end.

In addition, the tape support shown in Figure 1 is constructed so that it can be temporarily fixed with the spring spring 3 compressed, and the temporary fixation can be released only when it is desired to form a non-adhesive area. A spring can be applied to form the non-adhesive area. Further, especially when the non-adhesive region can be formed without using a spring spring, the spring spring may be left in a temporarily fixed state and processed without acting.

[Examples] [Examples] Next, examples will be shown for the purpose of clarifying the present invention, and the present invention is not limited to or restricted by these examples.

Example 1 A tape support 1 having the structure shown in FIG. 1 was prepared.

The tape support 1 is provided with laminated pieces 4 of removable adhesive paper with a width of 22 mm and a length of 5 mm stacked many times on the pedestal of the spring spring 3, and a cutter 5 adjacent to the chain portion.
It is equipped with.

A cellophane tape (manufactured by Chiban ■) having a width of 1.8 mm was attached as an adhesive tape 2 to the support.

Next, the cellophane tape was pulled out from the roll, passed over a small piece of removable adhesive paper, and cut with a cutter 5.

A piece of removable adhesive paper 4 was pressed onto the end face of the cut cellophane tape.

The tape was pressed onto a plastic plate.

As a comparative example, a similar adhesive tape was prepared by simply cutting it with scissors, unlike the cutting method using a tape support, and similarly pressed and pasted onto a plastic plate.

Next, when we started the work of peeling both from the plastic plate, the one made of the present invention with a small piece of removable adhesive paper on the end as a non-adhesive area was removed by pinching the chain part with your fingertips. It was easy to peel off, but
Adhesive tape that is simply cut with scissors and pasted is difficult to remove even if you twist the edges with your fingertips.
I was finally able to peel it off by flicking it with my fingernails, but the adhesive tape broke into small pieces and the plastic plate became very dirty.

[Effects of the Invention] According to the adhesive tapes with a peelable part and the tape support on which the adhesive tapes with a peelable part are formed according to the present invention, the following excellent functions and effects can be achieved by having the above-described structure. It is something to play.

(1) It is possible to provide a tape that can be easily removed from an object to be adhered after use. According to this tape, it can be easily peeled off when desired, and there is no fear that the adhesive tape will be cut in the middle or that the object to be adhered will be contaminated with debris from the adhesive tape or the like.

■ Peeling is easy, so the peeling surface is clean, and the non-adhesive side is not damaged.

(3) When a small piece of paper or film that can be written on with a writing instrument is used to form the non-adhesive area at the end of the adhesive tape, writing can be displayed by writing notes on the non-adhesive area. The non-adhesive area can also be conveniently used for organization, messages, etc. Furthermore, by using pieces of paper or film that are aesthetically pleasing in terms of color, shape, material, etc., they can also be used as pieces of tape that serve as clever memos or heading labels.

(4) Even if transparent tape is used as the adhesive tape, the position where the tape is used can be made clear.

(5) By using the tape support according to the present invention, a non-adhesive region can be automatically formed at the cut end each time the tape is cut.
