Description

  The present invention relates to a tack label attached to an adherend through an adhesive.

Conventionally, various products such as beverages, confectionery, cosmetics, and medicines are packaged in containers and boxes and distributed in the form of a package.
Tack labels are affixed to these packages for various purposes such as advertising of products, display of raw materials, and campaigns.
The tack label is configured by providing a solid adhesive layer on the lower surface of a label substrate on which design printing has been performed. The tack label is used by being attached to an adherend through an adhesive layer.
In addition, a tack label in which a label base material is embossed to improve decorativeness is also known (Patent Document 1). Such a tack label includes an embossed label base material provided with a first adhesive layer on the lower surface, a shape retaining sheet attached to the lower surface of the label base material via the first adhesive layer, And a second adhesive layer provided on the lower surface of the shaped sheet. Such a tack label is affixed to an adherend through the second adhesive layer (eg, [0009] to [0010] of Patent Document 1).

However, when the tack label comes into contact with the convex portion of the emboss from the upper surface side, the lower surface of the label base material corresponding to the convex portion of the emboss adheres to the shape-retaining sheet via the first adhesive layer, and as a result The convex shape of the emboss may be crushed.
In addition, when manufacturing a tack label, when the embossed label base material is pressed from the upper surface side of the label base material to adhere to the shape retaining sheet, the bottom surface of the embossed convex part adheres to the shape retaining sheet. In addition, there is a problem in that the convex shape of the emboss is crushed.
When the embossed unevenness disappears in this way, the significance of embossing the tack label is lost.

Japanese Utility Model Publication No. 6-37876

  Then, this invention makes it a subject to provide the tack label which was hard to be in the state which the unevenness | corrugation of embossing disappeared, and was excellent in decoration.

  The present invention relates to a tack label in which an adhesive layer is provided on the bottom surface of an embossed label base material, and the bottom surface of the label base material corresponding to the convex portion of the emboss is not bonded. provide.

  Since the lower surface of the label base material corresponding to the convex portion of the emboss is not adhered, the tack label has a label corresponding to the convex portion of the emboss when the label is attached to the adherend through the adhesive layer. There is no possibility that the lower surface of the base material adheres to the adherend. Therefore, even if a foreign matter or the like comes into contact with the upper surface of the label and the embossed convex portion is pushed in, this portion does not adhere to the adherend, so that the uneven shape of the emboss can be prevented from disappearing.

  Furthermore, the present invention has an upper layer base material that has an embossed upper layer base material and a lower layer base material that is laminated and bonded to the lower surface of the upper layer base material via an adhesive layer, and corresponds to the convex portion of the embossing. A tack label in which an adhesive layer is provided on the lower surface of the lower layer base material is provided between the lower surface of the lower layer base material and the upper surface of the lower layer base material.

Since the lower surface of the upper layer base material corresponding to the convex portion of the emboss is not bonded to the lower layer base material, the tack label presses the upper layer base material when the upper layer base material is laminated and bonded to the lower layer base material. Moreover, it can prevent that the lower surface corresponding to the convex part of an emboss adheres to a lower layer base material. Therefore, it can prevent that the convex part shape of an emboss is crushed at the time of manufacture of a label. Such a tack label is affixed to a to-be-adhered body through the adhesion layer provided in the lower surface of the lower layer base material. Even if a foreign matter or the like comes into contact with the upper surface of the label after pasting, it is possible to prevent the uneven shape of the emboss from disappearing for the same reason as described above.
Furthermore, since the upper layer base material is embossed, it is easily deformed into a curved shape, but the upper layer base material can be prevented from being bent by laminating the lower layer base material on the upper layer base material.

  The tack label according to the present invention can prevent the unevenness of the emboss applied to the base material from disappearing. Therefore, according to the present invention, it is possible to provide a tack label having excellent decorativeness while maintaining the embossed irregularities shown on the upper surface.

Hereinafter, the present invention will be specifically described with reference to the drawings. However, the lower surface of the base material refers to the surface on the side close to the adherend when the label 1 is attached to the adherend.
1 and 2A, reference numeral 1 denotes a tack label having an embossed label substrate 2 and having an adhesive layer 7 provided on the lower surface. The label 1 is formed in a predetermined shape (for example, a planar rectangular shape), and can be attached to an adherend through an adhesive layer 7 provided on the lower surface of the label 1.
In general, a plurality of labels 1 of this type are provisionally attached to a release paper, but the release paper is omitted in FIG.

  Specifically, the label 1 is provided between the upper layer base material 2 that is embossed, the lower layer base material 3 that is laminated and adhered to the lower surface of the upper layer base material 2, and the upper layer base material 2 and the lower layer base material 3. And between the lower surface of the upper layer base material 2 and the upper surface of the lower layer base material 3 corresponding to the convex portion 4 of the emboss. The non-adhesion part 6 provided and the adhesion layer 7 (henceforth a 2nd adhesion layer) provided in the lower surface of the lower layer base material 3 are included.

The uneven shape of the embossing of the upper layer base material 2 is not particularly limited, and can be an appropriate planar shape according to the design desired to be expressed. For example, in a plan view, one or a plurality of embossed convex portions having a width (area) of several μm to several mm can be formed. The embossing is usually formed on the upper layer base material 2 using an embossing tool (such as an embossing roll) having a protruding mold part obtained by casting a design to be expressed. When the embossing tool is applied from the lower surface side of the upper layer base material 2, the design expressed by the emboss appears in a convex shape on the upper surface of the upper layer base material 2. On the other hand, when an embossing tool is applied from the upper surface side of the upper layer base material 2, the design expressed by the emboss appears as a concave shape on the upper surface of the upper layer base material 2. In any case, an uneven shape can be formed on the upper surface of the upper layer base material 2 by embossing.
The embossed unevenness height (emboss depth) is not particularly limited, but if the height difference is too small, the decorativeness is inferior. On the other hand, if the height difference is too large, the upper layer base material 2 may break during emboss formation. Therefore, about 1-50 micrometers is preferable.

  The first pressure-sensitive adhesive layer 5 provided on the lower surface of the upper layer base material 2 is not particularly limited, and may be a known pressure-sensitive pressure-sensitive adhesive such as a rubber-based, acrylic-based, or urethane-based adhesive, a heat-sensitive adhesive that can be adhered by heating, or the like. It is provided by applying various adhesives. As the pressure-sensitive adhesive, it is preferable to use a pressure-sensitive adhesive having a peelable strength.

The non-adhesion part 6 covers the first adhesive layer 5 and is applied to conceal the adhesive force. The formation method of the non-adhesion part 6 is not specifically limited, For example, it provides by performing well-known non-adhesion processes, such as coating the ultraviolet curable ink (including printing), and the ink containing silicone. Can do.
This non-adhesive part 6 is provided at least on the lower surface of the upper layer base material 2 (first adhesive layer 5) corresponding to the embossed convex part 4.

Here, the “embossed convex portion” means the upper surface of the lower layer base material 3 due to the embossing of the upper layer base material 2 when the embossed upper layer base material 2 is bonded to the upper surface of the lower layer base material 3. (In the case of the label 1 that does not have the lower layer base material 2 as in the modification described later, the embossed label base material is adhered to the surface of the adherend). In this case, it refers to the part that partially lifts from the surface of the adherend). The embossing means that when one surface (for example, the upper surface) of the film is protruded in a convex shape, a concave shape is formed on the other surface (for example, the lower surface) of the film corresponding to the convex shape. .
As described above, when a design is expressed on the upper layer base material 2 by embossing, as a method of forming the embossing, an embossing tool is applied from the lower surface of the upper layer base material 2, and the design desired to be expressed is displayed from the upper surface of the upper layer base material 2. Two patterns are conceivable that project or project an embossing tool from the upper surface of the upper layer base material 2 and dent the design to be expressed from the upper surface of the upper layer base material 2. FIG. 2 illustrates the former case, and FIG. 3 illustrates the latter case.

  In the former case, a convex portion protruding from the upper surface of the upper layer base material 2 for design expression corresponds to the “embossed convex portion”. This is because when the upper layer base material 2 having the convex portion is bonded to the lower layer base material 3, the convex portion of the upper layer base material 2 is lifted. On the other hand, in the latter case, the periphery of the concave portion recessed from the upper surface of the upper layer base material 2 for design expression corresponds to the “embossed convex portion”. This is because when the upper layer base material 2 having a concave portion is bonded to the lower layer base material 3, the lower surface of the concave portion is bonded to the lower layer base material 3, and the periphery of the concave portion of the upper layer base material 2 is the lower layer. This is because it floats higher than the base material 3.

When the design to be expressed is projected from the upper surface of the upper layer base material 2, the non-adhesive portion 6 may be provided on the lower surface side corresponding to the embossed convex portion 4 as shown in FIG. In particular, as in the modification shown in FIG. 2 (b), the non-adhesive portion 6 is not even on the lower surface corresponding to the convex portion 4 of the emboss and the convex portion 4 and the periphery of the convex portion 4. It is preferable that the adhesion part 6 is provided.
Further, when a plurality of the embossed convex portions 4 are formed on the upper layer base material 2, as shown in FIG. 2C, the non-adhesive portion is also formed on the lower surface side corresponding to the adjacent embossed convex portions 4. 6 is preferably provided. In this case, as shown by a two-dot chain line in FIG. 2 (d), it is preferable to provide a non-adhesive portion 6 so as to surround the plurality of embossed convex portions 4.

When the design to be expressed is recessed from the upper surface of the upper layer base material 2, as shown in FIG. 3A, the non-adhesive portion 6 is provided on the lower surface side corresponding to the convex portion 4 of the emboss. In particular, as in the modification shown in FIG. 3B, the non-adhesive portion 6 is non-adhered to the lower surface corresponding to the convex portion 4 of the emboss and the convex portion 4 and the periphery of the convex portion 4. It is preferable that the part 6 is provided.
Furthermore, when the design to be expressed is recessed from the upper surface of the upper layer base material 2 and a plurality of the convex portions 4 of the emboss are formed on the upper layer base material 2, they are adjacent to each other as shown in FIG. It is preferable to provide the non-adhesion part 6 also on the lower surface side corresponding between the convex parts 4 of the emboss. In addition, when the design to be expressed is recessed from the upper surface of the upper layer base material 2 and the non-adhesive portion 6 is also provided on the lower surface side corresponding to the convex portion 4 between the adjacent embosses, FIG. As shown, the gap between the adjacent embossed protrusions 4 is lifted.

  In the modified examples (FIGS. 2B and 2C and FIGS. 3B and 3C) in which the non-bonding portion 6 is also provided around the embossed convex portion 4, the non-bonding portion 6 is The upper layer base material 2 is preferably provided so as not to reach the peripheral edge. This is because when the non-adhesive portion 6 is provided so as to extend to the peripheral portion of the upper layer base material 2, the non-adhesive portions of the upper layer base material 2 and the lower layer base material 3 are generated at the edge of the label, This is because the base material 2 may be peeled off from the lower layer base material 3.

  Similar to the first adhesive layer 5, the second adhesive layer 7 provided on the lower surface of the lower layer base material 3 is formed of various pressure-sensitive adhesives, heat-sensitive adhesives, etc. Strong ones are preferred. In addition, the 1st and 2nd adhesion layers 5 and 7 may be the same kind of adhesives, and can also use different adhesives, respectively.

As the upper layer base material 2, a film that can be provided with an uneven shape by embossing is used. The material of the film is not particularly limited. For example, a polyester film such as a polyethylene terephthalate film, a polyolefin film such as polyethylene or polypropylene, a polystyrene film, a polyamide film, a polycarbonate film, or a polyvinyl chloride film. A single layer such as a resin film or a laminated film of two or more layers can be used. Among them, it is preferable to use a polyester film (especially a biaxially stretched polyester film) such as a polyethylene terephthalate film because it is relatively rigid and can form a concavo-convex shape clearly. Moreover, a metal vapor deposition film can also be used as the upper layer base material 2. By using a metal vapor-deposited film as the upper layer base material 2, it is possible to construct a tack label 1 that exhibits diffused reflection of light and a more excellent appearance due to the synergistic effect of embossed irregularities and metallic luster.
The thickness of the film of the upper layer base material 2 is not particularly limited, but if it is too thin, it may break during embossing, and if it is too thick, it becomes difficult to form embossing. For example, when using a polyester film, the thickness is 25 to 75 μm. Is more preferable, and 38 to 50 μm is more preferable. In addition, when using a metal vapor deposition film, the thickness of the metal vapor deposition layer is not specifically limited, However, 40 nm or more is preferable from the point which ensures sufficient glossiness, and 45 nm or more is more preferable. Generally the upper limit of the thickness of a metal vapor deposition layer is about 70 nm.

FIG. 4 shows a preferred layer configuration of the upper layer base material 2. In this upper layer base material 2, a metal vapor deposition layer 21 is laminated on the lower surface of a transparent (including colored transparent) film 22, and a design print 23 is applied on the upper surface of the film 22.
In the design printing 23, for example, predetermined displays such as product names, advertisements, designs, and campaign applications are provided in single color or multicolor printing by gravure printing, flexographic printing, or the like.
The ink thickness for this printing is not particularly limited, but is preferably 10 μm or less from the viewpoint of preventing cracking of the ink layer during embossing. As the printing ink, known inks such as oil-based (solvent type) inks and water-based inks can be used, but the rigidity of the upper layer base material 2 can be increased by using inks that are cured by electron beams or ultraviolet rays. preferable.

The material of the lower layer base material 3 is not particularly limited. For example, a polyester film such as a polyethylene terephthalate film, a polyolefin film such as polyethylene or polypropylene, a polystyrene film, a polyamide film, a polycarbonate film, or a polyvinyl chloride film. A synthetic resin film such as a film, a single layer film such as paper, or a laminated film of two or more layers can be used. Moreover, a metal vapor deposition film, a metal foil laminated film, etc. can also be used. The material of the lower layer base material 3 is preferably the same as or higher than the film of the upper layer base material 2 from the viewpoint of preventing the upper layer base material 2 from being bent. Further, from the viewpoint of preventing the label from being bent due to shrinkage deformation due to heat or the like, the lower layer base material 3 is preferably a film of the same material as that of the upper layer base material 2, and when the same kind of film is used, the lower layer base material 3 is used. It is preferable to use a film having the same thickness as or thicker than that of the upper layer base material 2. Among them, it is more preferable to use a polyester film such as a polyethylene terephthalate film (especially a biaxially stretched polyester film) because it is relatively rigid.
Although the thickness of the lower layer base material 3 is not particularly limited, it is preferably 38 μm or more, and more preferably 50 μm or more, because if it is too thin, the effect of preventing the upper layer base material 2 from being bent cannot be expected. The upper limit of the thickness of the lower layer base material 3 is preferably 100 μm or less from the viewpoint of cost.

The label 1 can be manufactured, for example, by the following method.
The adhesive is applied to the lower surface of the long upper layer base material in a solid shape, and the upper layer base material is temporarily pasted on the release paper, and the adhesive is applied to the lower surface of the long lower layer base material. A lower layer base material is prepared which is coated in a solid shape and is temporarily pasted on a release paper.
The release paper is peeled off from the upper layer base material, and a non-adhesive treatment is performed on a predetermined area (area corresponding to the convex portion of the emboss) on the surface of the pressure-sensitive adhesive, and then temporarily attached to the release paper again. Embossing is performed using an embossing roll while aligning from the upper surface of the upper layer base material or the lower surface of the release paper so that a convex portion of the embossing is formed in the non-bonded region.
Then, the upper layer base material after the embossing is peeled off from the release paper, bonded to the upper surface of the lower layer base material, and passed between the pressing rollers. Adhere to. Finally, after punching out the laminated upper layer base material and lower layer base material into a predetermined shape, the punch is removed. Through this process, the tack label 1 of the present invention temporarily attached to the upper surface of the long release paper at a predetermined interval can be manufactured.

In the tack label 1 of the present invention, since the interlayer between the upper layer base material 2 and the lower layer base material 3 corresponding to the convex portion 4 of the emboss is not bonded, for example, when the label is manufactured, the embossing of the upper layer base material 2 Even if the convex portion 4 is pressed against the lower layer base material 3 by a pressing roller or the like, there is no possibility that the lower surface side corresponding to the convex portion 4 adheres to the lower layer base material 3 and the convex shape is crushed. That is, the embossed convex portion 4 can be restored after being crushed. Therefore, it can prevent that the embossing of the upper layer base material 2 lose | disappears at the time of manufacture. Similarly, when the tack label 1 is affixed to the adherend, it is possible to prevent the unevenness of the embossing from disappearing due to contact of foreign matter or the like with the embossed protrusion 4.
Furthermore, when the non-adhesion part 6 is provided to the periphery of the embossing convex part 4, it becomes difficult to produce a delicate wrinkle in the upper layer base material 2.

  Further, since the lower layer base material 3 is laminated and adhered to the embossed upper layer base material 2, the lower layer base material 3 holds the upper layer base material 2 in a flat shape, and the embossed upper layer base material 2 The curvature of the material 2 is prevented. Therefore, it is possible to provide a tack label 1 that is beautiful in appearance.

In addition, this invention is not restricted to the said embodiment, A design change can be carried out suitably. Hereinafter, although each modification of this invention is demonstrated, about the structure similar to the said embodiment, description is abbreviate | omitted and a term and a figure number may be used.
In the above embodiment, the non-adhesive portion 6 is provided on the lower surface of the first adhesive layer 5 of the upper layer base material 2 in order to make the interlayer between the upper layer base material 2 and the lower layer base material 3 corresponding to the convex portion 4 of the embossment non-adhesive. However, the non-bonding part 6 can also be provided on the upper surface of the lower layer base material 3 corresponding to the convex part 4 of the emboss.
Moreover, in the said embodiment, although the 1st adhesion layer 5 is provided in the lower surface of the upper-layer base material 2, and the non-adhesion part 6 is provided by performing the non-adhesion process which conceals the adhesive force, As shown in FIG. 5, an adhesive may be applied to the lower surface of the upper layer base material 2 except for the region corresponding to the convex portion 4 of the emboss. By coating the pressure-sensitive adhesive in this way, the pressure-sensitive adhesive coated portion becomes the first pressure-sensitive adhesive layer 5 and the pressure-sensitive adhesive non-coated portion (the portion corresponding to the embossed convex portion 4) is the non-bonded portion 6. It becomes. In this case, it is not necessary to perform non-adhesion treatment, but generally, as in the above-described embodiment, it is better to provide a solid pressure-sensitive adhesive, and to perform non-adhesion treatment in a desired region of them. The label 1 can be manufactured at low cost.

Furthermore, in the said embodiment, when the adhesive which is the grade which can peel the 1st adhesion layer 5 by hand is used, it is preferable to give desired design printing to the lower layer base material 3. FIG. This design printing is printed so that it can be visually recognized from the upper surface side of the lower layer base material 3 (for example, printing on the upper surface of the lower layer base material 3 or the lower surface of the transparent lower layer base material 3). In addition, when providing design printing and the 1st non-adhesion part 6 in the lower layer base material 3, design printing can be provided in the upper surface of the lower layer base material 3, and the 1st non-adhesion part 6 can be provided from it.
The label 1 can first visually recognize the contents printed on the lower layer base material 3 by peeling off the upper layer base material 2.
As the contents of this design printing, for example, by printing various campaigns such as speed lottery and application qualification, the tack label 1 of the present invention can be used as a campaign label.

Furthermore, in the said embodiment, although the label base material of the tack label 1 is comprised by the laminated body of the base material of the at least 2 layer of the upper layer base material 2 and the lower layer base material 3, it is comprised from the label base material of 1 layer. May be. The tack label 1 composed of a single-layer label base material can be configured by removing the lower layer base material 3 from the tack label 1 shown in the above embodiment. For example, as shown in FIG. 6A, a sticky adhesive layer 5 is provided on the lower surface of an embossed label base material 8 (corresponding to the upper layer base material), and the embossed convex part 4 is provided. The bottom surface of the tack label 1 in which the non-adhesive portion 6 is provided on the lower surface corresponding to the above, or the label base material 8 (corresponding to the upper layer base material) with embossing as shown in FIG. The tack label 1 is provided with a solid adhesive layer 5 and a lower surface corresponding to the embossed convex portion 4 and a non-adhesive portion 6 around it, as shown in FIG. 6 (c). The tack label 1 etc. in which the adhesive layer 5 is provided except for the lower surface corresponding to the convex part 4 of the embossing among the lower surfaces of the label base material 8 (corresponding to the upper layer base material) provided with .
In addition, although the tack label 1 shown in FIG. 6 has illustrated the thing when the design to express is protruded from the upper surface of the label base material 8, when the design to express is dented from the upper surface of the label base material 8 Is the same. That is, when the design to be expressed is recessed from the upper surface of the label substrate 8, as shown in FIG. 7, the lower surface of the recessed portion adheres to the adherend, and the periphery of the recessed portion is more than the adherend. Float up. Therefore, the periphery of the concave portion corresponds to the embossed convex portion 4, and the non-adhesive portion 6 is provided on the lower surface of the label base 8 corresponding to at least the periphery of the concave portion (embossed convex portion 4).

  Since the lower surface of the embossed convex portion 4 is not adhered to the adherend when the tack label 1 composed of the single layer label base material 8 is attached to the adherend, the embossed convex portion 4 does not adhere to the adherend. Even if it is pushed into the adherend side, it does not adhere to the adherend, and the concavo-convex shape can be maintained by the recoverability of the substrate 8.
