Description

Straight edge cutting easy to tear tape

This work is about a kind of tape, especially a kind of tape that can be cut by straight edges and easily torn by hand.

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 extremely long, with one side sticky and the other side rolled up without stickiness. When using, tear it off and stick it on the object. After pulling it out to a predetermined length, it is used with a tape stand or a knife to cut it. Although it is much more convenient to cut the tape with a tape stand than with a knife, the tape used with a tape stand is bulky and heavy, which can easily cause injuries to the arms and shoulders of workers who use it all day and for a long time.

Therefore, there is a method of tearing off the tape easily by hand without using a tape stand or knife, as shown in the first and second figures, comprising: a barrel 80, a tape strip 90, the tape strip 90 is made of a brittle material such as OPP, 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 the second figure for details), when the tape strip 90 is pulled out to the required length Yes, by making a tearing motion on the two long sides of the adhesive strip 90, the adhesive strip 90 can be directly cut by the notch 92 there and the brittle material characteristics. However, since the adhesive strip 90 can be cut at any position, its strength is relatively insufficient. Unexpected breaks are easily caused at any position of the adhesive strip 90, and the protective strength is poor. Moreover, the cross section of the adhesive strip 90 after being torn by hand is extremely uneven, as shown in the second figure, and the aesthetics is poor.

There is another method of tearing off the tape by hand without using a tape stand or knife, as shown in the third figure, comprising: a barrel 80A, a tape strip 90A, and a plurality of continuous holes 91A are provided on the tape strip 90A at fixed distances in a material removal manner. When the tape strip 90A is pulled out to a desired length, a tearing action can be performed from the long side of the continuous holes 91A of the tape strip 90A. The continuous hole 91A there can be used to directly pull the adhesive strip 90A apart. Although this method is convenient and does not require tools, a saw-like shape will be generated on the end surface of the adhesive strip 90A due to the provision of the continuous hole 91A. When the adhesive strip 90A is to be torn off, it will be broken by the saw-like portion of the adhesive strip 90A, and the adhesive strip 90A cannot be torn off smoothly at one time.

The author of this invention has the disadvantages of being easy to tear off adhesive tape by hand, being insufficiently strong and prone to unexpected breakage, and having an uneven cross section after tearing. Therefore, he came up with the idea of creating this product. After much discussion and trial production of samples, as well as many revisions and improvements, he finally launched this product.

The invention provides a straight-edge cutting and 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 arranged on the inner side surface, the adhesive tape strip is also provided with a preset length and a straight-line interval cutting section by non-material removal means, and the adhesive tape strip is rolled up around the barrel.

The main purpose of this creation is to cut the tape by hand, and the tape strip has a predetermined length and a straight-line interval cutting section without material removal. The tape strip can be automatically cut to a limited length without the use of a tape table or a knife, and the cross section of the tape strip is smooth after being torn by hand.

The following is a further description of the present invention in conjunction with the drawings of the preferred embodiments, in the hope that those familiar with the relevant technologies of the present invention can implement the invention according to the description in this manual.

First, please refer to the fourth to seventh figures, the creative straight-edge cutting and easy-to-tear adhesive tape 1 comprises: a tube body 10 and an adhesive tape strip 20, and the adhesive tape strip 20 comprises: a tape body 21, a release layer 22 and an adhesive layer 23.

The barrel 10 is a hollow ring having a preset width 11 and an outer diameter 12.

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 is provided with an inner side surface 212 and an outer side surface 213 opposite to the inner side surface 212 .

The release layer 22 is evenly and uniformly disposed on the outer surface 213. The release layer 22 can make the stickers adhered to the outer surface 213 easy to tear off. The release layer 22 can be transparent or have one of colors and patterns or a combination thereof.

The adhesive layer 23 is evenly disposed on the inner surface 212 with equal thickness, and can be transparent or have a color.

Furthermore, the adhesive tape 20 has a predetermined length L1, and a straight-line interval cutting section 201 is provided at every predetermined length L1 by non-material removal means, and the straight-line interval cutting section 201 has connecting sections 2011 and disconnecting sections 2012 arranged alternately.

The adhesive layer 23 of the inner side surface 212 of the tape strip 20 is rolled up and adhered to the periphery of the tube body 10. When rolled up more than one circle, the adhesive layer 23 of the inner side surface 212 adheres to the release layer 22 of the outer side surface 213 of the previous circle, thereby spirally rolling up, so that the adhesive layer 23 of the next circle can adhere to the release layer 22 and can be torn off without damage.

When the straight-edge cut and easy-to-tear adhesive tape 1 of the present invention is used to be adhered to an object 2, as shown in the eighth and ninth figures, the adhesive tape strip 20 is torn and pulled out from the very end of the straight-edge cut and easy-to-tear adhesive tape 1. When the adhesive tape strip 20 is pulled to the straight-line interval cutting section 201 of the non-material-removing means, the straight-line interval cutting section 201 of the non-material-removing means is automatically broken, so that the adhesive layer 23 of the tape body 21 can be adhered to the object 2, as shown in the tenth figure.

The structure of the above specific embodiment can obtain the following benefits:

The straight-edge cutting and easy-to-tear tape of the invention has a tape strip 20 with a predetermined length L1 and a straight-line interval cutting section 201 without material removal, so that the length can be limited and the tape strip 20 can be automatically cut without the use of a tape stand or a cutter. While maintaining the strength of the tape strip 20, it is still more convenient and easy to use. In addition, the cross section of the tape strip 20 after being torn by hand is smooth and aesthetically pleasing.
