Description

Technical Field

[0001] The utility model relates to an adhesive tape, in particular to a straight-edge cutting and easy-to-tear adhesive tape. Background Art

[0002] With the emergence of tape, it has become a necessity in people's daily life or industrial production due to its convenience and reliable adhesive properties. At present, most general tapes are very long, with one side sticky and the other side non-sticky and rolled up. When using, tear it and stick it on the object. After pulling out the predetermined length, it is cut with a tape dispenser or knife. Although it is much more convenient to cut the tape with a tape dispenser than with a knife, the tape used with the tape dispenser is bulky and heavy, which can easily cause arm and shoulder injuries to workers who use it all day and for a long time.

[0003] Therefore, there is a prior art method of easily tearing off the tape by bare hands without the need for a tape stand or knife, such as Figure 1 and Figure 2 As shown, it comprises: a barrel 80, a tape strip 90, the tape strip 90 is made of a brittle material such as OPP (polypropylene), and extends flatly, and the inner side of the tape strip 90 is coated with a sticky area 91 of adhesive, and the two long sides of the tape strip 90 are provided with a plurality of tiny notches 92 (see Figure 2 ), when the tape strip 90 is pulled out to the required length, a tearing action can be performed on the two long sides of the tape strip 90, and the tape strip 90 can be directly cut through the notch 92 and the brittle material characteristics. However, since the tape strip 90 can be cut at any position, it is relatively known that the strength of the tape strip 90 is not enough, and it is easy to break unexpectedly at any position of the tape strip 90, and the protective strength is poor. Moreover, the cross section of the tape strip 90 after being torn by hand is extremely uneven, such as Figure 2 As shown, the aesthetics is poor.

[0004] There is another prior art easy to tear tape by hand that does not require a tape stand or knife, such as Figure 3 As shown, it comprises: a barrel 80A, a tape strip 90A, and a plurality of continuous holes 91A are provided on the tape strip 90A at fixed intervals in a material removal manner. When the tape strip 90A is pulled out to a desired length, a tearing action can be performed on the long side of the tape strip 90A at the continuous holes 91A, and the tape strip 90A can be directly pulled apart through the continuous holes 91A there. Although this method is convenient and does not require tools, a serration will be generated on the end surface of the tape strip 90A due to the provision of the continuous holes 91A. When the attached tape strip 90A is to be torn off, it will be broken by the serrated portion of the tape strip 90A, and the attached tape strip 90A cannot be smoothly torn off at one time. Utility Model Content

[0005] In view of the disadvantages of the prior art that the adhesive tape can be easily torn off by hand, the adhesive tape is not strong enough and is prone to unexpected breakage, and the cross section is uneven after tearing, after much discussion and trial sample testing, as well as multiple revisions and improvements, the present utility model is proposed.

[0006] The utility model provides a straight-edge cutting easy-to-tear adhesive tape, comprising: a barrel and an adhesive tape strip, the adhesive tape strip comprising: a tape body and an adhesive layer, the barrel is annular and has a preset width, the tape body is flat and extends out, and has a tape body width that matches the barrel width, the tape body has an inner side surface and an opposite outer side surface, the adhesive layer is evenly and uniformly arranged on the inner side surface, the adhesive tape strip is also provided with a linear interval cutting section with a non-material removal means at every predetermined length, the linear interval cutting section has staggered connecting sections and disconnecting sections; the adhesive tape strip is rolled up and adhered to the periphery of the barrel with the adhesive layer on the inner side surface of the tape body, and when rolled up more than one circle, the adhesive layer on the inner side surface adheres to the release layer on the outer side surface of the previous circle, thereby forming a spiral roll.

[0007] Preferably, the adhesive tape strip further comprises a release layer, and the release layer is evenly and uniformly disposed on the outer side surface of the tape body.

[0008] Preferably, the adhesive layer is transparent or has color.

[0009] Preferably, the release layer is transparent.

[0010] The main purpose of the straight-edge cutting easy-to-tear tape of the utility model is that the tape strip is provided with a predetermined length and a straight-line interval cutting section without material removal means, which can automatically cut the tape strip by limiting the length without using a tape table or a knife, and the cross-section of the tape strip is smooth after being torn by hand.

[0045] The following is a further description of the preferred embodiments of the present invention in conjunction with the drawings, in the hope that those skilled in the art who are familiar with the present invention can implement the invention according to the description in this specification.

[0046] First, please refer to Figures 4 to 7 As shown, the straight-edge cutting and easy-tear adhesive tape 1 of the present invention comprises: a tube body 10 and an adhesive tape strip 20 . The adhesive tape strip 20 comprises: a tape body 21 , a release layer 22 and an adhesive layer 23 .

[0047] The barrel 10 is a hollow ring having a predetermined width 11 and an outer diameter 12 .

[0048] The belt body 21 is extended in a flat shape, has a belt body width 211 matching the width 11 of the tube body 10 , and has an inner side surface 212 and an outer side surface 213 opposite to the inner side surface 212 .

[0049] The release layer 22 is evenly and uniformly disposed on the outer side surface 213 . The release layer 22 can make the stickers adhered to the outer side surface 213 easy to tear off. The release layer 22 can be transparent or have a color, pattern, or a combination thereof.

[0050] The adhesive layer 23 is evenly disposed on the inner side 212 with equal thickness, and can be transparent or have color.

[0051] In addition, the tape strip 20 is provided with a predetermined length L1, and a linear interval cutting section 201 is provided at each predetermined length L1 without material removal means, and the linear interval cutting section 201 has connecting sections 2011 and disconnecting sections 2012 arranged alternately.

[0052] The adhesive layer 23 on the inner side surface 212 of the tape body 21 is rolled up and adhered to the periphery of the tube body 10. When rolled up more than one circle, the adhesive layer 23 on the inner side surface 212 adheres to the release layer 22 on the outer side surface 213 of the previous circle, thereby forming a spiral roll, so that the adhesive layer 23 of the next circle can adhere to the release layer 22 and can be torn off without damage.

[0053] When the straight-edge cutting easy-tear adhesive tape 1 of the utility model is used to stick to an object 2, Figure 8 and Fig. 9 As shown, the tape strip 20 is torn and pulled out by cutting the end of the easy-to-tear tape 1 by the straight edge. When the tape strip 20 is pulled to the straight-line interval cutting section 201 of the non-removing means, the straight-line interval cutting section 201 of the non-removing means is automatically broken, so that the adhesive layer 23 of the tape body 21 can be adhered to the object 2. Fig.10 shown.

[0054] The structure of the above specific embodiment can achieve the following beneficial effects:

[0055] The straight-edge cutting easy-to-tear tape of the utility model has a tape strip 20 with a predetermined length L1 and a straight-line interval cutting section 201 without material removal means, thereby limiting the length and automatically cutting the tape strip 20 without the need for a tape stand or a cutter. While maintaining the strength of the tape strip 20, it is still more convenient and easy to use, and the cross-section of the tape strip 20 after being torn off by hand is smooth and aesthetically pleasing.

[0056] The above is only a preferred embodiment of the utility model and is not intended to limit the scope of implementation of the utility model. The protection scope of the utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the utility model within the essence and protection scope of the utility model, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the utility model.
