Description

  The present invention relates to an anti-replacement label and a method for manufacturing the same that prevents the label from being attached to another product when the label attached to the product is peeled off.

  Since there is a person who tries to purchase a product at a price lower than a set price by removing a label attached to a product and attaching it to another product, a countermeasure has been demanded.

  For this reason, in the past, some incisions were made on the label, and this was affixed to the product so that when the label was peeled off, the label could be torn from the incision point, or the shape could collapse. Products that could not be pasted in a clean state were developed. (For example, refer to Patent Document 1.)

  However, there is a problem that the label with a notch can be peeled off in a state where the original shape is maintained and replaced with another product depending on how it is peeled off. In addition, there is a problem that the worker tends to lose its shape during the work of attaching the product to the product, and the quick application work cannot be easily performed.

  In addition, the back surface of the surface base material having the printing column and the surface of the sheet provided with an adhesive layer on the back surface are bonded via an auxiliary material having an adhesive force lower than the adhesive force of the adhesive layer, A label is disclosed in which at least the sheet remains attached to the product by the adhesive layer when the label attached to the product by the adhesive layer is peeled off. (For example, see Patent Document 2.)

Such a label having a larger number of layers than the conventional label can achieve the above-mentioned object, but has a complicated structure and may increase manufacturing material costs and process costs. Moreover, since the adhesion function by the auxiliary material remains in the peeled surface base material, it may not be perfect for countermeasures.

Small lot production is possible.

  An embodiment of an anti-stick label according to the present invention will be described with reference to the drawings. In addition, in this specification, the same code | symbol written over each figure shows the same or similar member and thing.

  As shown in FIG. 1, the anti-replacement label 2 of the present invention includes a transparent label material 4, a printed layer 6 formed on one side of the label material 4, and an adhesive layer 8 formed on the upper surface of the printed layer 6. Consists of The print layer 6 is formed by printing a character or a pattern of a predetermined display on one side of the label material 4 using UV curable ink. The pressure-sensitive adhesive layer 8 is made of an emulsion-type pressure-sensitive adhesive. The anti-sticking label 2 is manufactured by forming an emulsion-type pressure-sensitive adhesive layer on the side of the side of the label material 4 on which the printed layer 6 is formed, on which the printed layer 6 is formed.

  The sticking prevention label 2 of the present invention is stuck to a sticking object 10 such as an over-the-counter product as shown in FIG. The attached anti-replacement label 2 is configured such that characters and patterns made by the printing layer 6 can be seen through the transparent label material 4. Therefore, the printed layer 6 is printed by inverting the characters and patterns. Moreover, in this specification, transparency means that one side of the label material is visible, and the other side of the label material can be seen through the label material.

  When the anti-replacement label 2 attached to the sticking object is peeled off, as shown in FIG. 3, most or all of the printing layer 6 and the adhesive layer 8 remain on the surface of the sticking object 10, and the label material Only 4 is peeled off. Therefore, since the pressure-sensitive adhesive layer 8 is almost eliminated from the peeled label material 4, it is extremely difficult or impossible to stick the peeled label material 4 to another product. Even if the peeled label material 4 is pasted to another product using an adhesive prepared separately, the printed layer 6 is not completely left on the peeled label material 4 so The facts are easily revealed. Further, since the printed layer 6 is not completely left on the peeled label material 4, the replacement does not make sense.

  Although the mechanism by which such a phenomenon occurs is not completely elucidated, the components contained in the UV curable ink constituting the printing layer 6 affect the pressure-sensitive adhesive layer 8 made of an emulsion-type pressure-sensitive adhesive, and the pressure-sensitive adhesive layer 8 The adhesive strength of the pressure-sensitive adhesive layer 8 to the printing layer 6 is improved, and the adhesive strength of the pressure-sensitive adhesive layer 8 to the printing layer 6 is improved. It seems to be because it becomes bigger than. Especially, the component contained in UV curable ink which comprises the printing layer 6 affects the emulsifier (surfactant) contained in the emulsion which is a raw material composition of an emulsion type adhesive, and the adhesive layer 8's It is estimated that the adhesive strength to the label material 4 is reduced.

  FIG. 4 shows another embodiment of the anti-replacement label of the present invention. In FIG. 4, the anti-sticking label 2 a includes a label material 4, a printed layer 6 formed on one side 3 of the label material 4, an adhesive layer 8 formed on the upper surface of the printed layer 6, and the label material 4. It is comprised from the peeling layer 12 formed in the single side | surface 5 of this. As shown in FIG. 5, the label material 4 is formed in a band shape to form a band-shaped body 14 formed by connecting the anti-replacement labels 2 a, and the band-shaped body 14 is wound into a roll shape to form a roll label 16.

  The roll label 16 is attached to an existing labeler, and the belt-like body 14 is intermittently drawn out, cut into unit lengths, and attached to an object to be attached.

  When the other surface 5 of the label material 4, that is, one surface of the strip 14 has peelability with respect to the pressure-sensitive adhesive layer 8, the strip 14 is wound in a roll shape without the release layer 12 on one surface of the strip 14. The roll label 16 can be formed by turning. For example, when the belt-like body 14 is made of a resin film having a smooth surface, one side of the belt-like body 14 is peelable from the pressure-sensitive adhesive layer 8.

  In FIG. 6, the roll label 16a which makes the unit the sticking prevention label 2 (FIG. 1) is shown. The roll label 16 a has a plurality of anti-replacement labels 2 arranged in the longitudinal direction of the release sheet 18 on the surface of the strip-like release sheet 18. The roll label 16a is attached to an existing labeler equipped with a release sheet separating mechanism, and the release sheet 18 is intermittently drawn to separate the anti-replacement label 2 and attach it to the object to be attached.

  The roll label 16a is formed by, for example, forming a printed layer 6 in an array state in the longitudinal direction on one side of a strip-shaped label long material that becomes the label material 4 of the anti-replacement label 2 by punching, and then forming the strip-shaped label long A pressure-sensitive adhesive layer made of an emulsion-type pressure-sensitive adhesive is formed on the surface on which the printing layer 6 of the material is formed, and the label long material on which the pressure-sensitive adhesive layer is formed and the strip-shaped release sheet 18 are interposed via the pressure-sensitive adhesive layer. After sticking together, the long label material is obtained by half-cutting the label sheet 4 with the outline of the label material 4 leaving the release sheet 18 and removing unnecessary portions of the long label material.

  Alternatively, the printing layer 6 is formed in an array in the longitudinal direction on one side of a strip-shaped long label material that becomes the label material 4 of the anti-replacement label 2 by punching, while an emulsion type is formed on the peeling surface of the strip-shaped release sheet 18. A pressure-sensitive adhesive layer made of a pressure-sensitive adhesive is formed, and then a release sheet 18 having the pressure-sensitive adhesive layer formed on the surface on which the printed layer 6 of the strip-shaped long label material is formed is pasted via the pressure-sensitive adhesive layer. After the alignment, the long label material is half-cut with the outline of the label material 4 leaving the release sheet 18 to remove unnecessary portions of the long label material.

It is preferable to use hydrogenated petroleum resin or the like.

  The label material 4 may be made of a sheet material having a multi-layer structure made of different materials. In addition, when the sheet material constituting the label material 4 is paper such as ordinary paper or glassine paper, the printed layer is labeled when the label is peeled, compared to the case where the sheet material constituting the label material 4 is made of a film. It is difficult to take a measure with a chemical solution or a spatula to be transferred to the material 4, which is preferable. When the label material 4 is a sheet material having a multi-layer structure, it is preferable that the surface of the label material facing the adhesive layer is a surface of a sheet material made of paper. That is, it is preferable that the label material layer facing the adhesive layer among the label material layers is paper.

  In the present invention, the label material 4 on which the printing layer 6 is formed is manufactured by forming an emulsion-type pressure-sensitive adhesive layer on the side of the flaw on which the printing layer 6 is formed. The thickness of this layer is usually 5 to 100 μm, and preferably in the range of 10 to 50 μm. As a method for forming the pressure-sensitive adhesive layer, for example, an emulsion-type pressure-sensitive adhesive is directly applied to the surface of the label material 4 by a known method using a known coating apparatus, or a release sheet is provided. An emulsion-type pressure-sensitive adhesive is applied thereon by a known method to provide a pressure-sensitive adhesive layer, which is then adhered to the surface of the label material 4 by a known method using a known device, and the pressure-sensitive adhesive layer is transferred. A method or the like can be used.

The non-adhesive layer 32 is intermittently formed on the upper surface 30 of the adhesive layer 8. Thus, the upper surface 30 includes a region 34 where the non-adhesive layer 32 is formed and a region 36 where the non-adhesive layer 32 is not formed.

  When the anti-paste label 2b is peeled off after being stuck to the sticking object, a part of the printed layer corresponding to the area 36 of the label remains irregularly attached to the surface of the sticking object. Since the rest is in a state where the label is attached to the crocodile, the printed layer in the label area 36 is disturbed and unsightly. On the other hand, in the region 34, the non-adhesive layer 32 prevents the print layer from being transferred to the surface of the object to be adhered, and the print layer is clearly present as it is, so that the pattern formed by the region 34 and the region 36 is formed. When the label is peeled off when the label is peeled off, it can be seen at a glance whether it is unused or peeled off, and when it is attached to the object to be attached again, it is peeled off and attached again. You can clearly see that it is worn by looking at the front of the label.

  When the adhesive force between the sticking object and the part of the pressure-sensitive adhesive layer corresponding to the area 36 of the label is high, the part of the pressure-sensitive adhesive layer corresponding to the area 36 and the printed layer are mostly the surface of the sticking object. Since the printed layer remains clearly on the peeled label, only the printed layer corresponding to the region 34 remains as a pattern on the label, and it is clearer that the label has been peeled off after sticking. I understand.

  The pattern formed by the region 36 or the region 34 may be a geometric pattern such as a stripe shape, a sea island shape, a lattice shape, or a polka dot shape. It may be a symbol or a character shape representing a predetermined message. Characters such as “used” indicating that the label has been used are more effective in preventing re-sticking.

  FIG. 8 and FIG. 9 show the state of the printed surface of the anti-replacement label 2b before use and after being peeled off. Reference numeral 40 denotes a printed pattern. 8 and 9, the pattern formed by the region 34 and the region 36 is a striped pattern.

  In the present invention, the release layer 12 is formed on the side 35 opposite to the surface on which the printed layer 6 of the label material 4 of the anti-stick label 2b is formed, like the anti-stick label 2c shown in FIG. May be. The release layer 12 is useful when a strip formed by connecting the anti-replacement labels 2b is wound into a roll to form a roll label. In this embodiment of the roll label, the surface 35 may be peelable from the pressure-sensitive adhesive layer 8 instead of being provided with the release layer 12.

  The non-adhesive layer 32 is formed on the upper surface 30 by printing printing ink used for normal printing in a predetermined pattern. This printing ink may not contain a coloring material such as a pigment. This ink printing can be performed using a conventional printing apparatus. Examples of the printing method include letterpress printing, planographic printing represented by offset printing, intaglio printing represented by gravure printing, stencil printing such as screen printing, and the like. The thickness of the non-adhesive layer 32 is not limited, but is about 0.3 to 10.0 μm. The non-adhesive layer 32 is not limited to printing ink, and may be formed using a non-adhesive polymer, wax, or varnish as a material.

The adhesive layer 81 is formed on the upper surface 47 of the sheet, and the adhesive layer is not present in the intermediate portion 54 located between the one end portion 50 and the other end portion 52 of the anti-stick label 2d. An adhesive layer 81 is present at the other end 52. Such an adhesive layer is formed by a coating method such as a lip coater, comma reverse, or comma direct.

  In still another aspect of the present invention, as shown in FIG. 14, the anti-replacement label 2 e of the present invention includes a label material 4, a printed layer 46 formed on one surface 45 of the label material 4, and a printed layer 46. A non-adhesive layer on the upper surface of the adhesive layer 81 in the intermediate portion 54 located between the one end portion 50 and the other end portion 52 of the anti-sticking label 2e. 48 is formed. The non-adhesive layer 48 is formed in the same manner as the non-adhesive layer 32.

  Thereby, as for the sticking prevention label 2d and the sticking prevention label 2e, the one end part 50 and the other end part 52 have adhesiveness with respect to a sticking target object, and the intermediate part 54 is sticking with respect to a sticking target object. Does not have sex.

  As shown in FIG. 15, the anti-replacement label 2 d or the anti-replacement label 2 e has a ridge 62 where the surface 64 with the object to be adhered 60 and the other surface 66 intersect, and a certain surface 64 and other surface It is bonded to the surface 66 and used for sealing. The intermediate portion 54 (FIGS. 13 and 14) comes into contact with the ridge 62.

  In FIG. 15, the dotted line representing the intermediate portion 54 indicates a state before opening, and the solid line indicates a state where the intermediate portion 54 is cut along the longitudinal direction of the ridge 62 and opened. Each of the intermediate portions 54 divided into two by opening is curled and turned up in the direction of the one end portion 50 and the other end portion 52 to form a turn-up portion 70.

  The anti-replacement label 2d or the anti-replacement label 2e may be attached to the flat portion of the object to be attached. After sticking prevention label 2d or sticking prevention label 2e is stuck to flat part 72, intermediate part 54 is cut in the direction almost perpendicular to the direction from one end part 50 to the other end part 52, and turn-up part 70 A mode in which is formed is shown in FIG.

  15 and 16, the surface of the turn-up portion 70 has no adhesiveness or tackiness to the object to be adhered, so that once opened by cutting, the intermediate part 54 is attached to the object to be adhered. It cannot be restored to the state of being in contact with. Moreover, since the intermediate part 54 (FIGS. 13 and 14) is curled up and curled, even if it is forced to be pressed and fixed with a transparent adhesive tape from above, the sealing state is apparently restored and restored. This restoration operation is difficult.

  Such a turning-up phenomenon is caused by the intermediate portion 54 comprising layers of different materials (label material 4 and printing layer 40 or label material 4 and printing layer 40, adhesive layer and non-adhesive layer 48). It is a multi-layered structure, and it is considered that the latent strain stress generated in the manufacturing process of the label of each layer is manifested when the intermediate portion 54 is cut.

  When the label material 4 has a multi-layer laminate structure (for example, a laminate structure of glassine paper and polyolefin film), each of which has a different material layer, this turn-up phenomenon is more prominent and prevents re-sticking. Is preferable.

  In the embodiment of the present invention as shown in FIGS. 15 and 16, the label material 4 may be opaque. In that case, an adhesive layer is formed on one side of the printed label material. Moreover, the peeling layer may be formed on the other side. Alternatively, the other surface may be a surface that is peelable from the pressure-sensitive adhesive layer.

  In addition, the place which means the one end part and the other end part like the one end part 50 and the other end part 52 in the sticking prevention label 2d or the sticking prevention label 2e of the present invention strictly includes one end and the other end of the label. This is not only a region but also a region in the vicinity of one end and the other end with the intermediate portion 54 in between. That is, the anti-sticking label of the present invention has a pressure-sensitive adhesive layer formed in such a region, and a non-adhesive layer on the upper surface of the pressure-sensitive adhesive layer or a region where the pressure-sensitive adhesive layer is not present in the middle part between the regions. It has a configuration in which formed regions exist.

  The pressure-sensitive adhesive used for the pressure-sensitive adhesive layer 81 is not particularly limited, and can be appropriately selected from those conventionally used as pressure-sensitive adhesives. As the pressure-sensitive adhesive, various types of pressure-sensitive adhesives of emulsion type, solvent type or solventless type are used.

  Furthermore, examples of the pressure-sensitive adhesive include acrylic resin-based pressure-sensitive adhesives, urethane resin-based pressure-sensitive adhesives, and rubber-based pressure-sensitive adhesives. Among these, acrylic resin-based pressure-sensitive adhesives are preferable, and microspherical acrylic resin-based pressure-sensitive adhesives are particularly preferable because stable adhesive force can be easily obtained. Specific examples of acrylic resin-based adhesives include single weights such as acrylic acid, methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, ethyl methacrylate, butyl methacrylate, and acrylonitrile. Examples thereof include a polymer or a copolymer. Specific examples of the synthetic rubber pressure-sensitive adhesive include styrene-butadiene rubber, polyisobutylene rubber, isobutylene-isoprene rubber, isoprene rubber, styrene-isoprene block copolymer, styrene-butadiene block copolymer, styrene-ethylene-butylene block. Examples thereof include copolymers and ethylene-vinyl acetate thermoplastic elastomers. These pressure-sensitive adhesives can be used alone or in combination of two or more.

  The pressure-sensitive adhesive layer 81 can contain a filler such as silica, talc, clay, titanium oxide, aluminum oxide, calcium carbonate. By containing the filler, the concealment property can be improved. The pressure-sensitive adhesive layer 81 can further contain a tackifier, a softening agent, an anti-aging agent, and the like as necessary. Examples of the tackifier include rosin resin, terpene phenol resin, terpene resin, aromatic hydrocarbon-modified terpene resin, petroleum resin, coumarone / indene resin, styrene resin, phenol resin, xylene resin and the like. Examples of the softener include process oil, liquid rubber, and plasticizer. The pressure-sensitive adhesive layer 81 may contain a colorant. The colorant may be a dye or a pigment, or a mixture thereof. What is necessary is just to adjust content of a coloring agent so that it may become desired coloring. The pressure-sensitive adhesive layer 81 can be formed by various methods, and various methods can be used without any particular limitation. When the pressure-sensitive adhesive layer 81 is formed on the entire surface of one side of the label material 4, for example, the pressure-sensitive adhesive is an air knife coater, blade coater, bar coater, gravure coater, roll coater, curtain coater, die coater, knife coater, screen coater, Examples include a method of applying with a Mayer bar coater or a kiss coater and drying.

  In both the anti-replacement label 2d and the anti-replacement label 2e, a release layer may be formed on the side opposite to the surface on which the printing layer 61 is formed. The release layer is useful when a strip formed by connecting these anti-replacement labels is rolled into a roll label. In this roll label mode, one side of the label material 4 may be peelable from the pressure-sensitive adhesive layer 81 instead of being provided with a release layer.

  The printing layer 61 can be formed using ordinary printing ink. When the printing layer 61 is formed of UV curable ink and the pressure-sensitive adhesive layer 81 is formed of an emulsion-type pressure-sensitive adhesive, the above-described curling effect and the printing surface of the peeling portion described above are disturbed and printing on an object to be adhered is performed. Both the phenomenon of layer migration can be obtained, and the effect of preventing replacement can be further enhanced.

  Further, the anti-sticking labels 2b, 2c, 2d, and 2e may be arranged in a strip-shaped release sheet and wound into a roll shape and used as a roll label. Furthermore, it may be connected to form a band-like body, wound in a roll shape, and used as a roll label.

  Using a transparent glassine paper (product name: Crystal Window) and a polypropylene film laminate as the label material, the transparent glassine paper is repeated with UV curable ink (manufactured by Toyo Ink Co., Ltd .: type FDS) to repeat the unit pattern. The arranged reverse pattern was printed, dried at 95 ° C. for 10 seconds, and then irradiated with 2 3 KW ultraviolet lamps for 2 seconds to form a printed layer.

Emulsion of emulsion type adhesive (made by Toyo Ink Co., Ltd .: trade name: Olivevine type BPW5320) was applied to the surface of the label material on which the printed layer was formed, dried in a hot air oven at 105 ° C. for 75 seconds, and a thickness of 15 μm. The pressure-sensitive adhesive layer was formed to obtain a label substrate.
A striped pattern (width 3 mm, interval 2 mm) as shown in FIG. 8 was printed on the upper surface of the pressure-sensitive adhesive layer of this label base material to obtain a re-sticking label.

  This sticking prevention label was stuck on a commercially available release paper to give a label with a release paper.

  The label with the release paper was cut off in pattern units, and the release paper was separated, and then attached to a polished paper that looked like a price tag attached to a product. Next, when the anti-stick label was peeled off from the paper, a part of the adhesive layer and the printed layer remained on the paper, and the part peeled off from the paper and the other part remained on the label material in a striped pattern. It was clear that this was done.

  In addition, the present invention can be carried out in a mode in which various improvements, modifications, and changes are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention.

  The anti-replacement label of the present invention is widely used not only for labels for displaying over-the-counter product prices, but also for applications that require anti-replacement such as letter-like sealing labels and product packaging labels.
