Description

Technical Field

[0001] The invention relates to an adhesive tape for packing and sealing packaging materials for consignment, and in particular to an improved design of the adhesive tape body structure and the matching packaging material specifications. Background Art

[0002] Generally, after the goods are packed in cartons for mailing, all openings are sealed with tape before mailing to prevent the goods from falling out and being opened by others. Currently, most packing tapes are very long, with one side completely sticky and the other side rolled up without stickiness. When in use, they are torn off and stuck to the carton. After pulling out the required length, they are cut with a tape dispenser or a 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] With the existing design of adhesive tape having one side being sticky, tools must be used to cut the tape when opening the carton, and it is impossible to open the carton with bare hands, or it is extremely difficult to remove the tape from the carton when recycling the carton. Therefore, there is an invention such as Figure 1 , Figure 2 and Figure 3 The tape shown is easy to tear with bare hands.

[0004] The prior art easy-to-tear tape comprises: a tube body 50, a tape strip 60, the tape strip 60 is flat and extends to a certain thickness, and a sticky area 61 with adhesive is applied only in the middle section of the inner side surface of the tape strip 60, and non-adhesive areas 62 are formed on both sides of the middle section of the inner side surface of the tape strip 60, and the tape strip 60 is then rolled up on the outer periphery of the tube body 50. With this design, after the tape strip 60 is pulled out and pasted on a carton, only the sticky area 61 of the tape strip 60 can be pasted on the carton. When the tape strip 60 is to be torn off, the non-adhesive area 62 on either side can be used to conveniently tear off the tape strip 60, so as to achieve the purpose of opening the carton or removing the tape strip 60. When this tape strip 60 with uneven inner side surface is rolled up on the tube body 50, the tape strip 60 often deviates to one side of the tube body 50, such as Figure 4 As shown, the tape that is easy to tear by hand in this situation cannot be cut using a tape stand and can be cut using a knife.

[0005] A prior art method of easily tearing off the tape by hand without a tape stand or knife is as follows Figure 5 and Figure 6 As shown, it comprises: a barrel 70, a tape strip 80, the tape strip 80 is made of a brittle material such as OPP, and extends flatly, and the inner side of the tape strip 80 is coated with a sticky area 81 of adhesive, and the two long sides of the tape strip 80 are provided with a plurality of tiny notches 82 (see Figure 6), when the tape strip 80 is pulled out to the required length, a tearing action can be performed on the two long sides of the tape strip 80, and the tape strip 80 can be directly cut through the notch 82 and the brittle material characteristics. However, since the tape strip 80 can be cut at any position, it is relatively known that the strength of the tape strip 80 is not enough. The packaging adhered by the tape strip 80 is also easily unexpectedly broken at any position of the tape strip 80, and the protective strength is poor. In addition, the cross section of the tape strip 80 after being torn by hand is extremely uneven, such as Figure 6 As shown, the aesthetics is poor. Summary of the invention

[0006] The present invention is based on the fact that the prior art of easy-to-tear tape is to set no-glue areas on both sides of the long tape strip. Although the tape can be easily torn off the package by hand, the unequal thickness design will cause the tape strip to deviate to one side of the tube body when it is rolled into a roll, resulting in a high defective rate of the product. After the deviation, the tape strip cannot be cut using a tape table. In view of the above shortcomings, the present invention is proposed.

[0007] The present invention provides a packaging tape, comprising: a barrel and a tape strip, the tape strip comprising: a tape body, a release layer, an adhesive layer and two non-adhesive layers, the barrel is annular and has a preset width, the tape body is transparent and has an inner side and an opposite outer side, the release layer is arranged on the outer side of the tape body, the adhesive layer is arranged on the middle section of the inner side, the two non-adhesive layers are arranged on both sides of the adhesive layer of the inner side, after the two non-adhesive layers and the adhesive layer are formed, a glue-losing agent is coated to make the two sides of the adhesive layer lose their adhesiveness and become the non-adhesive layers, the non-adhesive layers and the adhesive layer are formed with equal thickness or close to equal thickness, the tape strip is provided with a preset length and an interval cutting section in a non-material removal manner, the tape strip is then rolled up on the periphery of the barrel and matched with a package.

[0008] The main purpose of the packaging tape of the present invention is to use adhesive on both sides of the inner side of the tape strip in combination with an adhesive loss agent, so that the adhesive can be converted into a non-adhesive layer without changing the thickness, and in combination with a non-material-removing interval cutting portion, the tape strip can be automatically cut off at a limited length without the need for a tape table or a cutter, making it more convenient and easy to use. In addition, the tape strip is set with a non-adhesive layer that does not change the thickness, which can maintain the winding quality of the packaging tape and make it easier to tear off the tape strip, and all processes can be completed by hand.

[0052] The following is a further description of the preferred embodiments of the present invention in conjunction with the drawings, and it is hoped that those skilled in the art can implement the invention according to the description of this specification.

[0053] First, please refer to Figures 7 to 10 As shown, the packaging tape 1 of the present invention comprises: a tube body 10 and a tape strip 20, the tape strip 20 comprises: a tape body 21, a release layer 22, an adhesive layer 23 and two non-adhesive layers 24, and the packaging tape 1 is matched with a packaging object 2 (such as a carton) of corresponding specifications.

[0054] The barrel 10 is a hollow ring having a predetermined width 11 and an outer diameter 12 .

[0055] The belt body 21 is a transparent flat extension having 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 .

[0056] The release layer 22 is evenly disposed on the outer side surface 213 with equal thickness. The release layer 22 can make the sticker adhered to the outer side surface 213 easy to tear off, and the release layer 22 is transparent.

[0057] The adhesive layer 23 is evenly disposed at the middle section of the inner side surface 212 with equal thickness and may have a color.

[0058] The two non-adhesive layers 24 are evenly disposed on both sides of the adhesive layer 23 of the inner side 212 with equal thickness and may have colors. The adhesive layer 23 and the non-adhesive layer 24 may be different colors or patterns, or a combination of transparency and any color.

[0059] The adhesive layer 23 and the two non-adhesive layers 24 are formed simultaneously with the adhesive. After the two non-adhesive layers 24 and the adhesive layer 23 are formed, a losing adhesive agent 241 or a colored losing adhesive agent 241 is coated to dissolve the losing adhesive agent 241 into the adhesive of the non-adhesive layer 24, or to cover the adhesive surface in a very thin manner, so that both sides of the adhesive layer 23 lose their adhesiveness and become the non-adhesive layer 24 (such as Fig.11 As shown), the non-adhesive layer 24 and the adhesive layer 23 are of equal thickness or close to equal thickness after being formed. In addition, the tape strip 20 is provided with a predetermined length L1, and a spaced cut section 201 is provided at every predetermined length L1 in a non-removal manner.

[0060] 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.

[0061] The package 2 is configured to cooperate with the packaging tape 1 . The package 2 has at least one opening to be closed. The opening of the package 2 has at least a maximum packaging length L2 , which is equal to the predetermined length L1 of the tape strip 20 .

[0062] When using, first Fig.12 It is observed that the non-adhesive layer 24 at the very end of the packaging tape 1 can tear the tape strip 20 and pull it out, and the end of the tape strip 20 is adhered to the longest packaging length L2 of the package 2 and is continuously pulled out. When the tape strip 20 is pulled to the interval cutting section 201 of the non-removal method, the interval cutting section 201 of the non-removal method is automatically broken, so that the predetermined length L1 just closes the longest packaging length L2, and the adhesive layer 23 of the tape body 21 closes the opening of the package 2. Fig.13As shown in FIG. 1 , when the packaging tape 1 on the packaging object 2 is to be torn off, the non-adhesive layers 24 on both sides of the tape body 21 can be pulled up by hand to tear off the tape strip 20 from the packaging object 2. Fig.14 shown.

[0064] The barrel 10 is a hollow ring having a predetermined width 11 and an outer diameter 12 .

[0065] The belt body 21 is a transparent flat extension having 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 .

[0066] The release layer 22 is evenly disposed on the outer side surface 213 with equal thickness. The release layer 22 can make the sticker adhered to the outer side surface 213 easy to tear off, and the release layer 22 is transparent.

[0067] The adhesive layer 23 is evenly disposed at the middle portion of the inner side surface 212 with a uniform thickness.

[0068] The two non-adhesive layers 24 are evenly disposed on both sides of the adhesive layer 23 of the inner side surface 212 with the same thickness.

[0069] The adhesive layer 23 and the two non-adhesive layers 24 are formed simultaneously using adhesive. After the two non-adhesive layers 24 and the adhesive layer 23 are formed, a debonding agent 241 is applied to make both sides of the adhesive layer 23 lose their adhesiveness to become the non-adhesive layers 24. After the non-adhesive layers 24 and the adhesive layer 23 are formed, the two are of equal thickness or close to equal thickness. In addition, the tape strip 20 is provided with a predetermined length L1, and a spaced cut section 201 is provided at every predetermined length L1 in a non-removal manner.
