Description

SEALING TAPE

The present invention relates to an adhesive tape.

Generally, the adhesive tape is used by applying a pressure-sensitive adhesive on one side of a cellophane or a vinyl film. Adhesive tapes are used to efficiently clean and improve the appearance and reinforcement of documents and books, and are widely used in various fields such as electrical insulation, industrial use, and packaging. Cellophane tapes to be.

The conventional adhesive tape has a problem that the cut surface after use is adhered to the tape again and it is difficult to find the adhesive surface when reused. In order to solve such a problem, the following documents are disclosed.

[Patent Document 1] Registration Utility Model No. 20-0309505 (2003.04.03 Announcement)

In the above Document 1, the non-adhesive portion is formed on a part of the tape, and the position where the tape is cut is located in the non-adhesive portion.

However, according to the above-mentioned Document 1, since it is necessary to cut only a predetermined cutting distance, there is a problem that the tape must be cut at an undesired length by the user, and when cutting a certain length, There is a problem that bonding and adhesion performance are deteriorated.

An object of the present invention is to provide an adhesive tape capable of easily finding a cutting line by forming a browning layer between an adhesive surface of a bonding tape and a coated surface.

According to an aspect of the present invention, there is provided an adhesive tape comprising: a first layer of a film material; A second layer formed on the lower surface of the first layer and made of an adhesive material for adhering the first layer to an object to be adhered; And a third layer formed between the first layer and the second layer, the third layer being made of a material whose color changes due to oxygen bonding.

In one embodiment of the present invention, the third layer may be composed of a polyphenol compound and a polyphenol oxidizing enzyme.

According to the present invention as described above, since the cut surface is browned by the combination of the cut surface and oxygen, there is an effect that the user can easily find the cut surface.

1 is a sectional view of an adhesive tape according to an embodiment of the present invention.
2 is an exemplary view for explaining a use state of the adhesive tape according to an embodiment of the present invention.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a sectional view of an adhesive tape according to an embodiment of the present invention.

As shown in the drawings, the adhesive tape of an embodiment of the present invention may include an adhesive layer 10, a browning layer 20, and a tape film layer 30. [

Usually, the adhesive tape is composed of an adhesive layer and a tape film layer. In the adhesive tape of the embodiment of the present invention, the browning layer 20 may be disposed between the adhesive layer 10 and the tape film layer 30 .

The adhesive layer 10 may be formed by applying an adhesive to the bottom surface of the tape film layer 30 and may be made of an adhesive material so that the tape film layer 30 adheres to the object to be adhered. Any adhesive material may be used as the adhesive layer 10 of an embodiment of the present invention regardless of its kind.

The tape film layer 30 is a film material such as polyester or nylon, and may be transparent, translucent or opaque, and is adhered to the top of the object to be adhered by the adhesive layer 10. However, the material of the tape film layer 30 of the embodiment of the present invention is not limited to those listed above, and various materials may be used.

The browning layer 20 is disposed between the adhesive layer 10 and the tape film layer 30 and may be made of a substance that is browned by contact with oxygen. For example, the browning layer 20 may comprise a polyphenol compound and a polyphenol oxidizing enzyme. Polyphenol oxidase is an enzyme that catalyzes the reaction of oxidizing a polyphenolic compound to form quinone.

According to the adhesive tape of the embodiment of the present invention, since the browning layer 20 is kept from being in contact with oxygen by the adhesive layer 10 and the tape film layer 30, When the tape is cut for use, the oxygen and the browning layer 20 adhere to each other at the cut surface and can be browned by an enzymatic browning reaction.

The enzymatic browning reaction refers to a reaction in which a polyphenol compound undergoes oxidative polymerization under the action of polyphenol oxidase in the presence of oxygen to produce a brown melamine pigment.

2 is an exemplary view for explaining a use state of the adhesive tape according to an embodiment of the present invention.

According to one embodiment of the present invention, when the user cuts the tape, the polyphenol compound in the browning layer 20 on the cut surface and the enzyme of the polyphenol oxidase The cut surface 2A is browned by the red browning reaction, and the user can easily find the cut surface, thereby reducing the time required for finding the cut surface.

In one embodiment of the present invention, polyphenol compounds and polyphenol oxidizing enzymes have been exemplified as constituent materials of the browning layer 20, but the present invention is not limited thereto, and thus, A combination of different materials that can be used is possible.

In addition, it is desirable that the amount of material used in the browning layer 20 be applied to such an extent that the user can identify the cut surface without interfering with the transparency of the tape.

In an embodiment of the present invention, it is described that the color changes to brown. However, the present invention is not limited thereto, and the color may be changed in various colors depending on the combination of the compound and the enzyme.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Accordingly, the true scope of the present invention should be determined by the following claims.

10: adhesive layer 20: tape film layer
30: browning layer

Claims (2)

A first layer of film material;
A second layer formed on the lower surface of the first layer and made of an adhesive material for adhering the first layer to an object to be adhered; And
And a third layer formed between the first layer and the second layer, the third layer comprising a polyphenol compound and a polyphenol oxidizing enzyme.
