Description

The present invention relates to an adhesive tape and a continuous adhesive tape, and particularly to an adhesive tape with a separator tape. The continuous adhesive tape is one in which two or more adhesive tapes are continuous in the longitudinal direction, and includes both a roll-shaped continuous adhesive tape and a fanfold-shaped continuous adhesive tape.

In the conventional adhesive tape with a separator tape, the adhesive is applied only to the part to be adhered, and the other part is called "glue killing", and the adhesive is not applied or once the adhesive is applied to the entire surface. The adhesive is partially removed after application. In FIG. 2, there are information displays 5c and 5d on one side of the information display tapes 1c and 1d, and adhesives 2a, 2b and 2c are applied only near the front end and the rear end on the opposite side. The adhesives 2a, 2b, and 2c are coated with the separator tape 3.

For example, in a wound adhesive plaster, an adhesive is applied around one side, and the other part of the same side is a gauze portion, but the adhesive is not applied.

Further, in the adhesive tape attached to the baggage handle in a ring shape at the boarding counter of the airfield, as shown in FIG. 5, the adhesive 2a is applied only near the tip and the rear end of the information display tape 1c having a certain length in the longitudinal direction. 2b is applied, and the adhesives 2a and 2b are coated with a long separator tape (not shown). After printing the barcode with letters, numbers, and symbols related to passenger information, boarding aircraft information, and boarding counter information on the print tape and exchange piece, the print tape and exchange piece are peeled off from the separator tape and printed. As shown in FIG. 6, the information display tape is attached to the baggage handle in a ring shape, and the exchange piece is attached to the passport and handed to the passenger. In FIG. 6, the information display tape 1c is bent into a ring with the side to which the adhesives 2a and 2b are applied inside, and the adhesives 2a and 2b are adhered. Then, the information display 5c is on the outside.

FIG. 6 shows a constant length information display tape as shown in FIG. 5 on the handle of a bag-shaped packaging material (flexible container bag, abbreviated as flexible container) for storing and transporting powdered or granular luggage. It is used by adhering the adhesives together in a ring shape.

As mentioned above, the information display tape used in a ring shape is a so-called "glue-killing process" in which the adhesive is applied only near the tip and the rear end in the longitudinal direction, and no adhesive is applied to the other parts. Glue.

However, the "glue-killing process" is a problem because the manufacturing process is complicated and the manufacturing cost is much higher than that of applying the adhesive on the entire surface.

In addition, delicate work of the fingertips is required to remove the separator tape from the conventional "glue-killing" adhesive tape. When working outdoors with gloves on, the separator tape cannot be removed properly, and sometimes the printed part is soiled or torn.

Therefore, it is possible to provide a new adhesive tape that is relatively inexpensive, can easily peel off the separator tape even when working outdoors with gloves on, and does not easily stain or damage the printed surface. It is an object of the present invention.

The object is the first aspect of the present invention according to claim 1, that is, an information display tape printed on one side and coated with an adhesive on the entire other side and most of the adhesive are covered. This is achieved by an adhesive tape that is laminated with the separator tape offset in the longitudinal direction. The width W1 of the information display tape and the width W2 of the separator tape may be substantially the same. Alternatively, the width W1 of the information display tape may be narrower than the width W2 of the separator tape.

The object is the second invention according to claim 2, that is, an information display tape on which an adhesive is applied to the entire surface and an IC chip is attached to a part of the same surface, and most of the adhesive. It is also achieved by an adhesive tape formed by laminating the separator tape covering the above with a longitudinal shift. The width W1 of the information display tape and the width W2 of the separator tape may be substantially the same. Alternatively, the width W1 of the information display tape may be narrower than the width W2 of the separator tape.

The object is the third invention according to claim 5, that is, the adhesive tape according to any one of claims 1 to 4 is partially fixed to each other at the longitudinal end of the separator tape. It is also achieved by connecting continuous adhesive tapes.

The object is the fourth invention according to claim 6, that is, the adhesive tape according to any one of claims 1 to 4 is partially fixed to each other at the longitudinal end of the information display tape. It is also achieved by a continuous adhesive tape formed by connecting.

When the continuous adhesive tape according to the present invention is pulled in the longitudinal direction to tear off the partial stoppers that connect the separator tapes to each other, a large shear force is applied between the separator tape and the adhesive in the vicinity of the partial stoppers. However, since the information display tapes are preliminarily slit and cut and separated from each other, a large shearing force does not act between the information display tape and the adhesive. As a result, the separator tape and the adhesive are separated in the vicinity of the partial stop, but the adhesive remains attached to a part of the information display tape and is exposed, so that a margin having a width W is generated.

Regarding the information display tape with a length of about 24 cm, if the dimension to be shifted in the longitudinal direction is 15 mm or more, the separator tape is difficult to peel off, and if it is 5 mm or less, the margin width is too small and the adhesion is insufficient during use. The present inventor has found.

Similarly, when the continuous adhesive tape according to the present invention is pulled in the longitudinal direction to tear off the partial stoppers connecting the information display tapes to each other, a large shear force is applied between the separator tape and the adhesive in the vicinity of the partial stoppers. Works. As a result, the separator tape and the adhesive are separated in the vicinity of the partial stop, but the adhesive remains attached to a part of the information display tape and is exposed, so that a margin having a width W is generated.

In the adhesive tape according to the present invention, even if the adhesive is applied to the entire surface of the opposite surface of the information display tape, the separator tapes are laminated so as to be displaced in the longitudinal direction, so that only a portion having a predetermined width at one end of the information display tape is laminated. Since the adhesive is exposed and the other parts are covered with the adhesive by the separator tape, it can be adhered only by the margin portion of the predetermined width of the adhesive tape, but cannot be adhered by the other part of the adhesive tape.

Hereinafter, examples of the continuous adhesive tape and the adhesive tape according to the present invention will be described with reference to the drawings.

1st Example FIG. 1 is a schematic view of a roll-shaped continuous adhesive tape according to the present invention, (a) shows a plane thereof, and (b) shows a side cross section thereof.

Information display tapes 1a and 1b having a length of about 24 cm and a width of about 5 cm are connected in the longitudinal direction via a slit (cut) 4. As shown in FIG. 7, the information display 5a on which characters, numbers, symbols, one-dimensional barcodes, and two-dimensional barcodes are printed on one side of the information display tapes 1a and 1b of the first embodiment is a human eye or bar. It is readable by a code reader. The material of the information display tape may be synthetic paper, YUPO paper, paper, plastic, or the like, which is flat and easy to print, and can be easily read visually or with a barcode reader.

Adhesive 2 is applied to the entire surface of the opposite surfaces of the information display tapes 1a and 1b.

Separator tapes 3a and 3b having the same length as the information display tapes 1a and 1b are connected in the longitudinal direction via the partial stopper 6.

Then, the separator tapes connected in the longitudinal direction via the partial stopper 6 cover the adhesive applied to the entire surface of the opposite surface of the information display tapes connected in the longitudinal direction via the slits 4 in the longitudinal directions. They are laminated with a deviation of the margin width W.

In the first embodiment, the partial stopper 6 is connected at only one point in the center of the tape width, and the other portions are cut in a straight line. It is a so-called one-point stop.

In other embodiments, the one-point stop may be changed to a two-point stop or a three-point stop. In the case of two-point fixing, the force required to tear off and separate the separator tape is larger than that of one-point fixing, and the shearing force acting between the adhesive and the information display tape and the adhesive and separator tape The shearing force acting between and is greater.

Next, the roll-shaped continuous adhesive tape of the first embodiment and the method of using the adhesive tape will be described.

The roll-shaped continuous adhesive tape is pulled out in the longitudinal direction, and then pulled in the longitudinal direction to tear off the separator tape. At that time, the separation tape and the adhesive are separated from each other by the shearing force in the portion of the margin width, but the adhesive area is overwhelmingly large in the other portion, so that the shearing force per unit area ( Shear stress is low and the separator tape and adhesive do not separate. On the other hand, since the information display tape is provided with slits for each predetermined length and separated, the information display tape and the adhesive are not separated by the shearing force.

The roll-shaped continuous adhesive tape is pulled in the longitudinal direction to tear off the partial stopper of the separator tape and separate it to obtain an adhesive tape as shown in FIG. Near one end of the information display tape 1a (right end in FIG. 3), the adhesive 2 is exposed without being covered by the separator tape. In the other part of the information display tape 1a, the adhesive 2 is covered with the separator tape 3a. The adhesive 2 is not attached to the other end of the separator tape (the left end in FIG. 3). The information display 5a, which is a print display, appears on one side of the information display tape 1a and can be read visually or by a barcode reader.

Adhesion when the adhesive tape is used will be described with reference to FIG.
In FIG. 4A, the information display tape 1a is rolled with one side facing outward, the free end of the separator tape 3a is projected to the outside of the circle, and the exposed portion of the adhesive 2 on the opposite side of the information display tape 1a and the separator. The tape 3a is brought into contact with the free end and adhered.
It is suitable when the printed display is arranged on one side of the bonded portion because there are few curved portions and many bonded portions. For example, it can be attached to ballpoint pens, fountain pens, trees, glasses, shoes, rings, aircraft baggage handles, newborn feet, livestock legs, marathon participants' arms, inpatients' ankles, etc. and used as tags.

In FIG. 4B, the information display tape 1a is rolled with one side facing outward, the free end of the separator tape 3a is inserted inside the circle, and the adhesive on the exposed end of the information display tape and the information display tape are added. Adhere by contacting one side of the end. It can be used as an information display by attaching it to the handle of a flexible container bag, Chinese cabbage, spinach binding, or the side mirror of an automobile.

2nd Example In the information display tape of the roll-shaped adhesive tape of the 2nd embodiment, an IC chip is attached.

In FIG. 8, a flexible thin IC chip 10 is arranged on a part of the opposite surface of the information display tape, and then an adhesive is applied to the entire surface of the opposite surface of the information display tape. In the portion where the IC chip is arranged, the information display tape, the adhesive, and the IC chip are laminated in this order. The display may be printed on one side of the information display tape corresponding to the IC chip so that the location where the IC chip is arranged can be known.

The structure of the roll-shaped adhesive tape of the second embodiment is the same as that of the first embodiment except for the arrangement of the IC chip.

The method of tearing off the adhesive tape from the roll-shaped adhesive tape of the second embodiment is also the same as that of the first embodiment.

The method of using the adhesive tape of the second embodiment is also the same as that of the first embodiment.

Third Example In the roll-shaped continuous adhesive tape of the third embodiment, the difference from the roll-shaped continuous adhesive tape of the first embodiment is that the separator tapes are connected in the longitudinal direction via the partial stopper. Instead, the information display tapes are connected in the longitudinal direction via the partial stopper. Others are the same as the roll-shaped continuous adhesive tape of the first embodiment.

Fourth Example In the roll-shaped continuous adhesive tape of the fourth embodiment, the difference from the roll-shaped continuous adhesive tape of the second embodiment is that the separator tapes are connected in the longitudinal direction via the partial stopper. Instead, the information display tapes are connected in the longitudinal direction via the partial stopper. Others are the same as the roll-shaped continuous adhesive tape of the second embodiment.

In the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment, the continuous adhesive tape is a roll-shaped continuous adhesive tape, but it can be changed to a fanfold-shaped continuous adhesive tape.

By using an IC chip, a large amount of information can be attached to an article, and RFID (radio frequency identification) is used to promote IoT (Internet Of Things), utilize it as big data, and traceability. It can contribute to the improvement of the Internet of Things and the utilization of logistics information by adding great value.
