BACKGROUND OF THE INVENTION
The present invention relates to a label that can be identified as having been peeled off without leaving an adhesive on the adherend (the material surface of the partner to which the label is to be attached).
[0002]
[Prior art]
2. Description of the Related Art Conventionally, for the purpose of preventing falsification of contents stored in a container or the like, there is a tamper-proof label that guarantees that there is no fact of opening. As such a conventional label, when the label is peeled off from the adherend such as a container to which the label is attached, a part of the printed layer and the adhesive layer remain on the adherend side, and both the label and the adherend are left. What remains after the label is peeled off is widely used.
[0003]
Such a label structure will be described with reference to FIG. FIG. 7A is a configuration diagram of a conventional tamper-proof label. As shown in FIG. 7 (a), the conventional tamper-proof label 101 prints a release layer 103 having peelability on the back surface of the transparent film 102 and covers the back surface of the transparent film 102 and the release layer 103. 104 is formed, and an adhesive layer 105 is formed on the printed layer.
[0004]
As shown in FIG. 7B, when the anti-tamper label 101 is attached to the adherend 106 and peeled off, the release layer 103 is peeled off from the transparent film 102, and the printed layer 104a formed on the release layer 103 is removed. The adhesive layer 105a formed on the printed layer 104a is cut from the printed layer 104b formed on the back surface of the transparent film 102 and the adhesive layer 105b formed on the printed layer 104b, and remains on the adherend 106.
[0005]
As a result, the tamper-proof label 101 after peeling can recognize that the pattern in which the peeling layer 103 is formed appears and peels the tamper-proof label 101, and also by the printed layer 104a left on the adherend 106. It can be known that the tamper-proof label 101 that has been pasted has been removed.
[0006]
[Problems to be solved by the invention]
However, when using the conventional anti-tamper label, the adhesive residue remaining on the adherend side may be mixed into the contents, especially in containers such as beverages, foods, pharmaceuticals, and cosmetics. There was a problem that it was not suitable for use. In addition, there is a problem that the residual piece attached to the container side damages the appearance of the container, and the stickiness of the residual piece attaches dust.
[0007]
Accordingly, an object of the present invention is to provide a tamper-proof label that can recognize that the tamper-proof label has been peeled off and that does not leave an adhesive on the adherend.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the tamper-proof label according to the present invention is a printing layer in which a release layer having peelability is printed in a predetermined pattern on the back surface of a transparent film, and the back surface and the release layer of the transparent film are covered. Forming a cushion layer having a property of irreversibly elastically changing on the printed layer, and forming an adhesive layer on the cushion layer, the tamper-proof label being pasted When peeled off, the release layer is peeled off from the transparent film, and the print layer formed on the release layer is lifted off from the print layer formed on the other transparent film, and the release layer and the print layer are peeled off. Remains in between the cushion layer and the transparent film in a state of being bitten into the cushion layer.

DETAILED DESCRIPTION OF THE INVENTION
[First embodiment]
Embodiments of a tamper-proof label according to the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram of a usage state of a tamper-proof label according to the present embodiment.
[0010]
As shown in FIG. 1, the tamper-proof label 1 of the present embodiment guarantees that there is no unsealing for the purpose of preventing tampering of contents stored in containers such as beverages, foods, pharmaceuticals, and cosmetics. , Formed in various shapes such as strips and squares, and the entire circumference of the separation layer A3 between the lid A1 and the container body A2 of the container A or a part of the separation layer B3 between the cap B1 and the container body B2 of the container B Used to paste.
[0011]
Such a label structure will be described with reference to FIG. As shown in FIG. 2, the tamper-proof label 1 prints a release layer 3 having peelability on the back surface of the transparent film 2, and forms a print layer 4 so as to cover the back surface of the transparent film 2 and the release layer 3. A cushion layer 5 having cushioning properties and film properties is formed on the printed layer 4, and an adhesive layer 6 is formed on the cushion layer 5. The surface of the transparent film 2 may be subjected to special mat processing.
[0012]
The transparent film 2 is a double-sided in-line film easy-adhesion coated product formed of a transparent polymer film such as vinyl, polypropylene, or polystyrene, and can be subjected to original printing on the surface.
[0013]
The release layer 3 is formed of UV (ultraviolet curable) silicon resin. The release layer 3 is made of silicon, Teflon (registered trademark), matte particle, oil or fat represented by acrylic ester of higher alcohol such as stearyl acrylate, cellulose ester represented by nitrocellulose, or ether. It may be formed. A plurality of release layers 3 are formed by a pattern such as “opened” at a predetermined interval by letterpress printing, flexographic printing, screen printing, or the like.
[0014]
The print layer 4 is printed when the anti-tamper label 1 attached to the containers A and B is peeled off, and displays a pattern of the release layer 3 that is peeled off when the anti-tamper label 1 is peeled off.
[0015]
The cushion layer 5 is formed by applying or laminating a coating layer that can be processed on the same line using means such as UV resin, hot melt, or dry lamination. As the cushion layer 5, urethane acrylate-based, polyester acrylate-based, polymer acrylic monomer solution, etc. are used. These urethane acrylate-based, polyester acrylate-based, polymer acrylic monomer-dissolved materials and the like have a characteristic that they are solidified with a tension that shrinks after application, and when a part is peeled, this part shrinks and irreversibly changes elastically.
[0016]
The adhesive layer 6 is formed by applying various adhesives having rubber elasticity on the printing layer 4. Moreover, the adhesion layer 6 is good also as a film whose base material of the double-sided adhesive tape which has a base material is 4-50 micrometers. Depending on the adherend, the adhesive properties of the double-sided adhesive tape having an adhesive or a substrate can be changed.
[0017]
As shown in FIG. 3, the release layer 3 is peeled from the transparent film 2 when the tamper-proof label 1 attached to a part of the separation layer B3 between the lid B1 and the container body B2 which are adherends is peeled off. Then, the printed layer 4 a formed on the release layer 3 is cut from the printed layer 4 b formed on the back surface of the transparent film 2. Then, the peeled release layer 3 is peeled off from the adherend together with the tamper-proof label 1 in a state where the release layer 3 has bitten into the cushion layer 5 due to the film property and cushioning property of the cushion layer 5.
[0018]
As shown in FIG. 4, the tamper-proof label 1 after being peeled is peeled off from the transparent film 2 by the irreversible elastic deformation of the cushion layer 5 so that the release layer 3 and a part of the print layer 4 a overlapping the release layer 3 are removed. Peeling and shrinking of the cushion layer 5 cause a gap S between the transparent film 2 and the peeling layer 3, thereby causing a shift in the positions of the printing layer 4 a and the printing layer 4 b from the transparent film 2. In other words, the region provided with the release layer 3 (printing layer 4a) is translucent, the region not provided with the release layer 3 (printing layer 4b) remains in a complete state, and “opened” or the like in which the release layer 3 is formed. Pattern appears. This makes it possible to recognize that the tamper-proof label 1 once peeled is peeled off even if it is again attached to the adherend, and the adhesive layer 6, the printing layer 4a, and the release layer 3 are attached to the adherend. There is no residue.
[0019]
In this way, when the tamper-proof label 1 is pasted and peeled off, the print layer 4a formed on the release layer 3 by peeling off the release layer 3 from the transparent film 2 is printed on the other transparent film 2 Recognizing that the tamper-proof label 1 has been peeled off because the printed layer 4a is lifted off from the layer 4b and stays between the cushion layer 5 and the transparent film 2 in a state where the printed layer 4a is lifted off. In addition, the tamper-proof label 1 can be provided in which the adhesive does not remain on the adherend and the appearance of the adherend can be kept hygienic.
[0020]
Next, a method for manufacturing the tamper-proof label 1 will be described. A release layer 3 made of a component having a releasing effect is printed on the back surface of the transparent film 2. The necessary number of colors (printing layer 4) is printed so as to cover the release layer 3, and the same material is used to cover the printing layer 4 using means such as UV resin, hot melt, or dry laminate having cushioning properties and film properties. A coating layer (cushion layer 5) that can be treated on the line is applied or laminated. Then, an adhesive (adhesive layer 6) is applied so as to cover the cushion layer 5.
[0021]
A release paper or a release film is laminated on the adhesive layer 6, and is extracted from the surface side (transparent film 2 side) with a punching blade mold having a required shape (insert a blade up to the adhesive layer 6). Unnecessary portions of the matt processed film are removed, and trace processing is performed in accordance with a delivery form such as slitting or sheet cutting.
[0022]
[Other embodiments]
Next, another embodiment of the tamper-proof label according to the present invention will be described with reference to the drawings. FIG. 5 is a cross-sectional view of the tamper-proof label according to the present embodiment. About the part which overlaps with said 1st embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.
[0023]
As shown in FIG. 5, the tamper-proof label 11 according to this embodiment includes a transparent film 12, a release layer 13, and a print layer 14 instead of the transparent film 2, the release layer 3, and the print layer 4. Unevenness such as a satin pattern is formed on the boundary surface H between the layer 13 and the printing layer 14.
[0024]
In this way, by forming a satin pattern or the like on the boundary surface H, when the tamper-proof label 11 is peeled off and a gap S is generated between the transparent film 12 and the release layer 13, the release layer 13 is not provided. While the display in the region (printing layer 14b) does not change, the transparency of the region (printing layer 14a) provided with the release layer 13 is further reduced. Thereby, a pattern such as “opened” on which the release layer 13 is formed can be recognized more clearly.
[0025]
If the purchaser cannot know that the tamper-proof label 1 is attached to the product, as shown in FIG. 6, the characters 15 such as “opened” are displayed at the position where the tamper-proof label 1 of the container B is pasted. May be displayed in an auxiliary manner.
[0026]
【The invention's effect】
As described above, the tamper-proof label is printed on the back surface of the transparent film in a predetermined pattern, and the print layer is formed so as to cover the back surface and the release layer of the transparent film. Forming a cushion layer having a property of irreversibly elastically changing on the layer, and forming an adhesive layer on the cushion layer, the tamper-proof label, when the anti-tamper label is pasted and removed, The release layer is peeled off from the transparent film, and the printed layer formed on the release layer is lifted off from the printed layer formed on the other transparent film, and the lifted and peeled release layer and the printed layer bite into the cushion layer. In this state, it is configured to stay between the cushion layer and the transparent film.
[0027]
Thus, it is possible to recognize that the tamper-proof label has been peeled off, and to provide a tamper-proof label capable of maintaining the appearance of the adherend in a sanitary manner without any adhesive remaining on the adherend. Can do.
