Description

  The present invention relates to a label (tack) attached to the surface of a container such as a PET bottle, a metal can, or a bottle.

  Campaign labels that are used for application tickets for lotteries and prizes are used to promote the sale of products. As the campaign label, there is known a tack label composed of a display portion on which campaign information or the like is printed and an attaching portion for attaching to a product or the like on the back side (see, for example, Patent Document 1). . Such a campaign label is used in a state where only the end portion of the campaign label is attached and fixed to a container so as to stand out so as to stand out at the time of product display.

  Patent Document 1 discloses a tack label in which a mask printing layer is formed so as to cover the entire area of the display part and leave the sticking part among the exposed surface of the adhesive layer on the back side of the label. . Such a tack label is supplied with the release paper pasted on the adhesive layer side, but since the mask printing layer (adhesive suppression) is floating from the release paper, an automatic label sticker (labeler) is used. At times, there was a problem that the label was easily dropped from the release paper and the workability of sticking was poor.

  An object of the present invention is to provide a label capable of improving productivity by preventing label peeling and dropping from a release paper in a labeler at the time of label sticking.

  As a result of intensive studies to achieve the above object, the present inventors have provided a masking layer at a specific position on the surface of the adhesive layer, thereby preventing label peeling and dropping from the release paper when using a labeler. It has been found that after sticking to a container, the floated state can be maintained, and the present invention has been completed.

  That is, the present invention is a label that is stuck in a state of standing outward from the outer peripheral surface of the container main body, and is provided with a printing layer on one side of the label base material and an adhesive layer on the other side. And leaving a container sticking portion formed on a part of the outer peripheral edge of the label on the surface of the adhesive layer, and locally leaving the outer peripheral edge of the label facing the container sticking portion or the vicinity thereof. Provided is a label characterized in that a masking layer is formed.

  Further, the present invention is a label that is stuck in a state of standing outward from the outer peripheral surface of the container body body, and is provided with a printing layer on one side of the label base material and an adhesive layer on the other side. The container adhesive part formed on a part of the outer peripheral edge of the label is left on the surface of the adhesive layer, and the adhesive layer in a part other than the container adhesive part is weakened as a whole. And a mask characterized in that a masking layer is formed in a pattern.

  Furthermore, the present invention is a label stuck in a state of standing outward from the outer peripheral surface of the container body body, and is provided with a printing layer on one side of the label base material and an adhesive layer on the other side. And a masking layer is formed on the surface of the adhesive layer, leaving a container sticking part formed on a part of the outer peripheral edge of the label, and the outer peripheral edge of the label facing the container sticking part in the masking layer. Alternatively, a label is provided in which the vicinity thereof is locally weakly tackified.

  According to the label of the present invention, it is difficult to peel off or fall off from the release paper in the labeler at the time of automatic application, so that it can be stably attached to products, etc., and sticking to unnecessary parts and adhesion of dust are minimized. Thus, productivity can be remarkably improved.

  Embodiments of the present invention will be described below with reference to the drawings as necessary. 1A and 1B show an example of a label of the present invention, where FIG. 1A is a front view, FIG. 1B is a sectional view taken along line AA of FIG. 1A, and FIG. 1C is a perspective view with a cover label turned. It is. A label 1 shown in FIGS. 1 (a) to (c) is composed of a sticking part 1a and a non-sticking part 1b attached to a container or the like on a part of the outer peripheral edge of the label, and the non-sticking part 1b. Includes two adhesive portions 1c provided locally on the outer peripheral edge of the label facing the container sticking portion 1a. More specifically, as shown in FIG. 1B, the label 1 has a printed layer 11 and a release layer 14 on one side of a label substrate 10, and an adhesive layer 12 and a masking layer 13 on the other side. The cover label 2 is provided on the release layer 14. The cover label 2 is provided with a printing layer 21 and an adhesive layer 23 on one side of a label base material 20 and a printing layer 22 on the other side. Further, as shown in FIG. 1C, the printed layers 11 and 21 can be visually recognized by peeling the cover label 2. Such a label 1 is used in a state where only the sticking portion 1a is stuck to a container or the like and the non-sticking portion 1b is raised, and is usually referred to as a POP (point of purchase) label. Since such a label is conspicuous when a product is displayed, it may be used as a campaign label.

  The label base materials 10 and 20 may be any material having self-supporting properties, for example, paper; synthetic paper (for example, polyester synthetic paper, polyolefin synthetic paper, etc.); polyester film (for example, polyethylene terephthalate, polybutylene). Films such as terephthalate), olefinic films (for example, films such as polypropylene resins such as polypropylene and propylene-ethylene copolymers), plastic films such as polystyrene films; and laminates thereof. In particular, when the label substrate 10 is formed of a transparent material, the transparent sticking portion 1a is configured and is stuck on the cylindrical label attached to the container-side trunk portion. Moreover, concealment of the written description of the cylindrical label can be suppressed or prevented. In addition, a label base material is not limited to a transparent base material, For example, a white base base material may be sufficient.

  The thickness of the label base materials 10 and 20 can be appropriately selected within a range that does not impair the strength as a base material or the workability of attaching the label base material, and is, for example, about 5 to 200 μm, preferably about 20 to 100 μm. The surface of the label substrate 10 may be subjected to conventional surface treatments such as corona discharge treatment, plasma treatment, flame treatment, and acid treatment in order to improve adhesion and printability.

  The print layer 11 in the print label 11 and the cover label 2 is a layer that displays a description of the campaign, etc., and the print layer 22 in the cover label 2 informs the presence of the label, A layer with symbols, patterns, colors, etc. The printing layers 11, 21, and 22 can be formed by a normal printing method (for example, letterpress printing, flexographic printing, gravure printing, screen printing, etc.) using a conventional UV ink or the like. As shown in FIG. 1, the print layer 11 may be provided on a portion of the one side of the label substrate 10 excluding the sticking portion 1 a, or may be provided on the entire surface. The thickness of the printing layers 11, 21, 22 is, for example, about 1 to 8 μm, preferably about 2 to 5 μm.

  As the adhesive constituting the adhesive layer 12 and the adhesive layer 23 in the cover label 2, an adhesive commonly used in the field of labels and the like can be used. Preferred adhesives include adhesives that can be peeled off from the adherend, such as conventional pressure-sensitive adhesives such as acrylic adhesives and rubber adhesives. In particular, when the adhesive layer 12 is formed of a transparent adhesive, the transparent label base 10 and the transparent sticking part 1a are configured, and a cylindrical label or the like attached to the container side body part. Also, when concealing and sticking, it is possible to suppress or prevent concealment of the written description of the cylindrical label. The thickness of the adhesive layers 12 and 21 can be appropriately set in consideration of adhesiveness and the like, but is generally 5 to 100 μm, preferably about 10 to 30 μm.

  The masking layer 13 can be formed by a normal printing method (for example, letterpress printing, flexographic printing, gravure printing, screen printing, etc.) using a masking agent. The masking agent is preferably one that can form a non-tacky coating layer that can be cured by ultraviolet rays on the adhesive layer 12, and conventional UV inks (ultraviolet curable inks) can be used. The UV ink is usually an oligomer component, a monomer component, a photopolymerization initiator, and, if necessary, additives (for example, photopolymerization accelerator, stabilizer, wax, anti-mist agent, colorant, lubricant, drying agent). , Wetting agents, viscosity improvers, etc.).

  The masking layer 13 can be formed by solid printing (solid printing), leaving the adhesive part 1a and the adhesive part 1c on the surface of the adhesive layer 12. The thickness of the masking layer 13 can be appropriately selected within a range that does not impair the transparency, the operability when sticking the label 1 to a container or the like, and the sticking stability, and is usually about 1 to 30 μm, preferably about 2 to 15 μm. It is.

  The label of the present invention leaves a container sticking part formed on a part of the outer peripheral edge part of the label on the surface of the adhesive layer, and the label outer peripheral part facing the container sticking part or the vicinity thereof is locally And a masking layer is formed. In FIG. 1 (a), the sticking part 1a located at the edge of one side of the substantially square label 1 corresponds to the "part of the outer peripheral edge of the label", and the opposite side of the side where the sticking part 1a is located. The adhesive portions 1c located at two places (both corners) at both ends correspond to the portions left locally on the “label outer peripheral edge facing the container sticking portion”. The part locally left in the “label outer peripheral edge facing the container sticking part” is constituted by, for example, a spot having one or more squares, circles, triangles, etc. separated from the container sticking part. Is done. The shape of the label is not limited to a square shape. For example, in a circular label, the adhesive layer surface has an adhesive part formed on an arc edge part of the circumference, and both ends of the arc facing (separating) the adhesive part A masking layer may be formed leaving

  The release layer 14 has a function of adjusting the adhesive force of the adhesive layer 23 to improve the peelability of the cover label 2 and easily exposing the print layer 11. Such a release layer 14 can be formed, for example, by applying a varnish containing a known or conventional release agent such as a silicone release agent using a conventional coating method. In addition, it is preferable that the peeling layer 14 has transparency to the extent that the printing layer 11 can be visually recognized. The thickness of the release layer 14 is, for example, about 0.3 to 10 μm, preferably about 0.5 to 5 μm.

  In addition, the label 1 in FIG. 1 has a form in which the cover label 2 is laminated so as to be peelable, and an aspect in which the peeling layer 14 in the label 1 and the adhesive layer 23 in the cover label 2 are laminated (FIG. 1). In addition to this, for example, an adhesive layer 23 is provided on the printed layer 12 of the label 1 and a release layer 14 is provided on the cover label 2, and the adhesive layer 23 side and the release layer 14 side are laminated ( (Not shown). In addition, when the adhesive layer 23 is made of a weakly sticky adhesive that can be easily peeled off, the peeling layer 14 is not necessarily provided.

  Moreover, the cover label 2 may be attached in the form which folded the thing which has an area larger than the non-sticking part 1b inside so that it could just coat | cover the non-sticking part 1b. Such a cover label 2 is preferable in that the amount of information that can be visually recognized after peeling is increased.

  The label of the present invention may be in a form connected to the cover label 2 at one edge portion (not shown). In this case, even after the cover label 2 is peeled off, the label can be kept integral without the cover label 2 being separated. For the connection between the label and the cover label 2, a method in which a hot melt adhesive is melt applied to one end edge of each surface where these labels contact can be used. The label of the present invention includes those that do not have a cover label.

  FIG. 2 is another example of the label of the present invention. The label 1 'in FIG. 2 has a masking layer 13' formed on the surface of the adhesive layer 12 leaving the sticking part 1a and the adhesive part 1c '. The adhesive portion 1c ′ corresponds to a portion left locally in the above-mentioned “near the label outer peripheral portion facing the container sticking portion”. In addition, "the vicinity of the label outer peripheral part facing the container sticking part" means the periphery of the label outer peripheral part facing the container sticking part, for example, the sticking part 1a in the non-sticking part 1b. It is a position close to the outer peripheral edge of the label facing the attaching part 1a, preferably a position approaching the center of the label from the outer peripheral edge of the label facing the attaching part 1a.

  The label of the present invention is usually provided in a form in which release paper (not shown) is laminated on the adhesive layer 12 through the masking layers 13 and 13 'having the above-described form, and is attached to the container using a labeler or the like. It is pasted. As for the conventional label, only a part of the outer peripheral edge of the label (the container sticking part) is held on the release paper, so the non-sticking part that is not sticky on the entire surface tends to flutter within the labeler, causing the label to peel off. It was. On the other hand, according to the label of the present invention, since it has the above-described configuration, the non-adhered portion is caused by the exposed portion (for example, the adhesive portion 1c in FIG. 1) of the adhesive layer left locally other than the container adhering portion. Is held on the release paper, and the label can be prevented from peeling off or falling off from the release paper in the labeler, and can be stably adhered to the container. The adhesive portions 1c and 1c ′ are preferably provided at a position and a range that can exhibit adhesiveness to the extent that the label and the release paper are connected within the labeler before being attached to the container.

  Moreover, the label of this invention leaves the container sticking part formed in a part of label outer periphery part on the said adhesive bond layer surface, and the adhesive bond layer in parts other than the said container sticking part as a whole is weak. The masking layer may be formed in a pattern so as to be adhesive. FIG. 3 is still another example of the label of the present invention. The label 1 ″ in FIG. 3 includes a masking layer 13 ″ formed in a lattice shape and an adhesive portion 1c ″ interspersed with the entire range (non-adhered portion 1b) excluding the adhered portion 1a on the surface of the adhesive layer 12. That is, the non-sticking portion 1b does not completely lose the tackiness, but the sticking portion 1c ″ is minute and scattered, and thus has a weak stickiness. When attached to the container by 1a, it is held in a state of being raised. The masking layer 13 ″ may be formed in a pattern that can reduce the adhesiveness of the adhesive layer, and may be formed in a stripe shape, a mesh shape, or a dot shape in addition to a lattice shape. According to this, it is possible to prevent the label 1 ″ and the release paper from being connected to each other by the non-sticking portion 1b having weak adhesiveness, thereby preventing the label from peeling off or falling off in the labeler.

  In the label of the present invention, a masking layer is formed on the surface of the adhesive layer, leaving a container sticking part formed at a part of the outer peripheral edge of the label, and facing the container sticking part in the masking layer. The outer peripheral edge of the label or the vicinity thereof may be weakly adhered locally. That is, in “the outer periphery of the label facing the container sticking portion or the vicinity thereof”, for example, in the portion shown in the adhesive portion 1c in FIG. 1 (a), the adhesive portion 1c ′ in FIG. The masking layer may be formed in a pattern so as to be weakly tackified. Examples of the pattern forming the masking layer include a lattice shape, a stripe shape, a mesh shape, and a dot shape. According to such a label, the outer peripheral edge of the label facing the container sticking part or its vicinity has weak adhesiveness locally, so that the release paper is connected to prevent the label from falling off in the labeler. When sticking to a container by the sticking part, it can be held in a raised state.

  According to the label of the present invention, since it has the above-described configuration, it is possible to effectively prevent peeling and falling off in the labeler. In particular, it is suitable for a label that has been easy to float from a release paper and has a label that has been easily removed from within the labeler, such as a label having a cover label on a non-sticking portion.

  The label of the present invention is used by being stuck in a state of standing outward from the outer peripheral surface of the container main body. FIG. 4 is a schematic view showing an example of use of the label of the present invention. In FIG. 4, the label 1 of the present invention is attached to the surface of a cylindrical label (a label on which a product name or design is printed) 4 attached to the outer peripheral surface of the side barrel of the container 3. Are attached so as to overlap each other, and the non-adhering part 1b does not come into contact with the container or the like, stands up outside (for example, above the attaching part 1a), and is held in a floating state. The label can be attached using a conventional label automatic attaching machine (labeler) or the like. In particular, according to the label of the present invention, since it has the above-described configuration, even when a high-speed labeler with a line speed of about 500 lines / min is used, it is possible to prevent the label from dropping off from the release paper and improve productivity. it can.

  The label of the present invention can be applied to various bottles such as PET bottles such as soft drinks, metal cans such as canned coffee, bottles (bottles) such as drinks, pharmaceuticals, and beer. The shape and size of the label are appropriately selected according to the type of container to be attached.

  Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited to these examples.

Example 1
A transparent label of a laminated film in which a polyethylene terephthalate film having a thickness of 50 μm as a transparent label substrate, an acrylic pressure-sensitive adhesive layer (thickness 20 μm) as an adhesive layer, and a biaxially stretched polyethylene terephthalate film (thickness 38 μm) as a release paper are laminated. A pattern is printed on the surface of the substrate by letterpress printing, and then a release layer is formed by applying a varnish containing a silicone release agent, and an adhesive film composed of a label substrate and an adhesive layer, and a release paper, Separated. The container sticking part 1a formed on a part of the outer peripheral edge part of the label is left on the surface of the adhesive layer of the adhesive film, and the outer peripheral part of the label facing the container sticking part 1a is left locally. (Adhesive part 1c), the surface of the adhesive layer is coated with a UV curable ink (masking agent) by letterpress printing, and a masking layer having a thickness of 8 μm is formed at the site shown in FIG. The masking layer was cured by UV irradiation with a UV lamp and then the release paper was overlaid.
Separately, an acrylic pressure-sensitive adhesive layer (thickness 20 μm) as an adhesive layer was laminated on one side of a 38 μm-thick polyethylene terephthalate film (label base material), and a white solid-printed printing layer was laminated on the other side. A cover label was prepared. The surface of the cover label on the side of the adhesive layer was overlapped so as to be in contact with the release layer to produce a label as shown in FIG.
When the obtained label was automatically affixed to the container using a labeler, the label was not peeled off or dropped off in the labeler, and the work efficiency was excellent.

Comparative Example 1
In Example 1, a label was prepared by performing the same operation as in Example 1 except that a masking layer was provided on the surface of the adhesive layer so that only one edge portion 1a remained tacky.
When the obtained label was automatically affixed to the container using a labeler, the label peeled off when the label was fed into the labeler, or dropped when the label was folded back, resulting in poor workability.
