Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of an adhesive tape having an adhesive-coated surface and an adhesive-uncoated surface, the adhesive-uncoated surface serving as a picking piece.

[0002]

[Prior Art]

 One side of the tape in the longitudinal direction is left as the non-adhesive coated surface and the other side is the adhesive coated surface, and the cuts formed in the width direction in the wound state are formed at predetermined intervals in the longitudinal direction. The resulting adhesive tape is known.

[0003]

[Problems to be solved by the device]

 The unit pressure-sensitive adhesive tape cut out from the roll of the long tape as described above at each cut had a non-adhesive-coated surface continuous to at least one side, and this functioned as a picking portion. The present invention is intended to provide an adhesive tape which is an improvement of this type of adhesive tape and in which the above-mentioned knob portion can be utilized for any useful or unnecessary purpose.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention uses one end of one side of an adhesive tape as a non-adhesive coated surface and the other part as a non-adhesive coated surface. The adhesive tape is characterized in that it has a configuration in which a perforation line such as a perforation capable of cutting out the adhesive-uncoated surface portion is formed in the vicinity of the boundary with the cloth surface.

In addition, according to the present invention, one end of one surface of a tape body having a fixed length or a long length is used as a non-adhesive-coated surface that serves as a picking portion, and the other portion is used as an adhesive-coated surface. Form a perforation line like a perforation that can cut the non-adhesive coated surface near the boundary between the non-adhesive coated surface and the adhesive-coated surface. It is also characterized in that the adhesive tape has a structure in which cut lines such as slits are formed in the width direction and the cut lines in the width direction are formed at predetermined intervals in the length direction. Is.

In any of the above, it is preferable that the surface not coated with the adhesive is formed as a colored surface different from the surface coated with the adhesive. Further, it is preferable that the perforation line capable of cutting off the adhesive-uncoated surface portion is a perforation line, but it is not limited to the perforation line. Similarly, the adhesive-coated surface end and the adhesive-uncoated surface end are The slit is preferably a slit line formed in the width direction, but is not limited to the slit.

[0007]

[Action]

 It is possible to cut and remove the non-adhesive-coated surface by a cutting line and leave only the adhesive-coated surface for use.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The unit pressure-sensitive adhesive tape 1 shown in FIG. 1 forms a pressure-sensitive adhesive coated surface 2 with one side left on one side, and uses the pressure-sensitive adhesive non-coated surface 3 on the one side so that perforations are formed to separate the both sides. The cut line 4 is formed by It is preferable that the pressure-sensitive adhesive-uncoated surface 3 is colored as desired in advance, because the distinction from the pressure-sensitive adhesive-coated surface 2 is visually clear, but both surfaces may be the same color or transparent.

FIG. 2 exemplifies a tape winding body suitable for obtaining the unit adhesive tape 1. The pressure-sensitive adhesive tape 5 as the roll is a long tape made of synthetic resin made of OPP or other appropriate material, or an arbitrary material, except for the appropriate width portion on one side of the width. The adhesive-coated surface 2 with the adhesive applied to the inner surface), the adhesive-uncoated surface 3 of the above-mentioned appropriate width portion, and the cut line 4 formed in the longitudinal direction at the boundary between the both surfaces 2 and 3. It is wound around a winding core 6 and has cut lines 7 formed at predetermined intervals in the circumferential direction of the tape winding body and extending in the width direction of the winding body.

The cut line 7 preferably has a slit (cut line) 7 that is cut in the radial direction from the surface of the winding body to the outside of the winding core, leaving the end of the adhesive-uncoated surface 3 slightly. It is formed so as to reach the end of the adhesive application surface 2. Reference numeral 8 indicates a slit-unformed portion.

The slits 7 may be formed over the entire width of the tape, and when the tape is formed with a tearing direction which is easy to tear in the width direction, for example, no adhesive is used. A slit may be formed only on the coated surface 3 part. Further, in these cases, the adhesive can be applied to the end surface portion so that the end portion of the non-adhesive surface 3 does not flicker.

The pressure-sensitive adhesive tape 5 having the above-mentioned configuration can be peeled off by peeling the unit pressure-sensitive adhesive tape 1 by hooking the end of the pressure-sensitive adhesive-uncoated surface 3 with a fingertip. Is attached to a tape holder equipped with claws that are oriented in the circumferential direction and pressed in the tape core direction, and the adhesive tape 5 is rotated or the claw side is rotated while the claws of the unit adhesive tape 1 are rotated. It is also possible to cut and raise 3 parts of the adhesive-uncoated surface, and pick it up with a finger to peel off the unit adhesive tape 1.

The adhesive tape may have a structure different from that of the roll body. For example, in the adhesive tape 5A shown in FIG. 3, a plurality of bundles (5 bundles in the example in the figure) formed by bundling a plurality of unit adhesive tapes are arranged side by side in a continuous manner. Either the lowest unit adhesive tape 1 of multiple bundles is adhered to one release paper of the entire size, or the adhesive coated surfaces 2 and 2 of adjacent bundles are adhered with adhesive. It may be done as a set.

In the above embodiment, the adhesive-uncoated surface 3 is formed only on one side of the unit adhesive tape 1, but as shown in FIG. 4, the adhesive-coated surface is formed in the middle portion of the tape width. A unit adhesive tape 1A having a structure in which 2 is provided, adhesive-uncoated surfaces 3 and 3 are provided on both sides, and cut lines 4 are formed at substantially boundaries of each surface, can be used as the unit adhesive tape. The adhesive tape can be configured as a wound body or a bundle to obtain 1A.

[0015]

[Effect of the device]

 According to the pressure-sensitive adhesive tape having the above-mentioned configuration, the surface not coated with the pressure-sensitive adhesive is in a free state, which is convenient for peeling the unit pressure-sensitive adhesive tape from the roll or bundle, etc. When the unit adhesive tape is used for any purpose such as dressing, if it is preferable that the surface without the adhesive is attached, it can be used as it is. When it is preferable not to have the non-adhesive coated surface part such as a packaging form where it is not desirable to leave parts or catches, use the tear line along with sticking the unit adhesive tape. Since the uncoated surface can be easily cut into pieces and cut off, the use of unit adhesive tape can be very convenient.
