Description

  The present invention is affixed to a container such as a returnable box or a packing box for transporting goods, and forms a pasting area for overlaying another label thereon, and another sticker or label is pasted and peeled off. The present invention relates to a pressure-sensitive adhesive sheet that can be repeated, and a container to which the pressure-sensitive adhesive sheet is attached.

  A reusable returnable box is used as a container for transporting goods such as products and parts between companies and within companies. It is common to affix a detailed label indicating the item to be sent and the destination to the returnable box. Moreover, the label which shows an expiration date, and the label which shows a shelf life in the case of a foodstuff may be stuck. In the operation of the returnable box, the pasted label is peeled off every time the role is finished, and another label describing the contents of the next article transportation is pasted. However, since these adhesive labels are coated with an adhesive called high-viscosity with high adhesive strength, it is difficult to replace them. When peeling off, the detail label may be broken, or in the case of a cardboard returnable box, the surface of the cardboard may be peeled off. In order to peel off the label neatly and prevent damage to the returnable box, adhesive paper using weak adhesive type or low release type adhesive with low adhesive strength may be used as the specification label. The risk of peeling along the way increases. Such inconvenience occurs not only in returnable boxes for transporting articles, but also in storage containers.

  In order to facilitate the peeling of the detail label, various ideas have been made on the returnable box. A typical example is that a part of a plastic return box is provided with irregularities called wrinkles to form a labeling area. When the detail label is affixed to the textured area, the adhesive of the detail label comes into contact with only the convex part of the texture, so that the sticking area is reduced and the peeling work is facilitated. However, as the detailed label is repeatedly attached and peeled, the adhesive enters and adheres to the recesses, resulting in a problem that the detailed label is stuck and difficult to peel off.

  In addition, a method has been proposed in which a label provided with irregularities is pasted on a box and used as an area for attaching a detailed label. This is to emboss a flexible label base material such as foil paper to form irregularities and obtain the same effect as the above-mentioned embossing. For example, if it sticks to the return box which is not textured, the part will become a label sticking area | region. If it is attached to a cardboard box, it becomes possible to apply and peel off the detailed label. Irregularly provided labels are convenient because the surface can be modified and the labels can be attached and peeled regardless of the material of the container.

  However, this uneven label is not suitable for printing. For example, if you print the name of the company that owns the box on foil paper, and then emboss it, you will get a concavo-convex label with the company name printed on it, but it will be difficult to see the company name due to the unevenness in the printed part. . Furthermore, if the printing ink is peeled off by repeating the sticking and peeling of the detail label, the aesthetics are impaired.

  Therefore, the present applicant has proposed an adhesive paper in which an image is printed on the surface of the label and a release agent layer made of an ultraviolet curable silicone compound is provided on the printed surface (Japanese Patent Laid-Open No. 10-268769). The printing ink is not peeled off even if the label that has been laminated is peeled off by forming a release agent layer on the surface. However, the release agent layer of this label is as thin as several microns, and is not intended to be repeatedly applied and peeled off. Therefore, a durable pressure-sensitive adhesive sheet for labeling has been demanded.

  The present invention was made in order to solve the above-described problems, and another label is overlaid on the label application area provided on the surface, and the application and peeling can be repeated, which is excellent in durability and printing. It is an object of the present invention to provide a pressure-sensitive adhesive sheet for forming a labeling region capable of maintaining the quality of a printed image. Moreover, an object of this invention is to provide the container which has the adhesive sheet for label sticking area | region formation, and can repeat lamination | pasting and peeling of another label.

  In order to solve the above problems, the present invention has the following configuration.

The invention according to claim 1 is a pressure-sensitive adhesive sheet in which an adhesive layer is provided on one side of a translucent or opaque sheet and an image is formed on the other side. A transparent adhesive, a transparent film, and a transparent release agent layer are covered with a laminate film laminated in this order, and another label can be applied to and peeled off from the transparent release agent layer surface of the laminate film. It is an adhesive sheet for forming a label application region.
The invention according to claim 2 is a pressure-sensitive adhesive sheet in which an adhesive layer is provided on one side of a translucent or opaque sheet and an image is formed on the other side. A transparent adhesive, a transparent film, and a transparent release agent layer are coated with a laminate film laminated in this order, and a label application region forming adhesive that can repeat the pasting and peeling of another label on the transparent release agent layer surface of the laminate film. A container having a labeling region characterized by having a sheet.

The pressure-sensitive adhesive sheet for forming a label application region of the present invention can easily form a label application region for applying a label to a returnable box or the like. Since the surface of the sheet, which is the label application area, is a laminate film with a transparent release layer provided on a highly durable transparent film, it will not be damaged by repeated application and peeling of another label such as a specific label. . In addition, images such as letters and designs printed on the adhesive sheet for forming the label application region can be visually observed through the laminate film (transparent adhesive layer, transparent film, transparent release agent layer). Furthermore, since the image is covered with a laminate film, it is not damaged even if the application and peeling of another label are repeated.
Moreover, the container which has a label sticking area | region of this invention can repeat sticking and peeling of another label like a detailed label with respect to the label sticking area | region. Since the label can be peeled cleanly, the container will not be damaged, and the label will not be broken and fragments will not remain.

  Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 shows a cross-sectional view of the pressure-sensitive adhesive sheet 1 for forming a label application region of the present invention.

  The pressure-sensitive adhesive sheet 1 for forming a label application region of the present invention prints an image 11 on the surface of a pressure-sensitive adhesive sheet 4 composed of an opaque base material sheet 2 and a pressure-sensitive adhesive layer 3, and the entire surface of the pressure-sensitive adhesive sheet 4 including the image 11 is transparent. The film 6, the transparent pressure-sensitive adhesive layer 7, and the transparent release agent layer 8 are covered with a laminate film 9 that is laminated in this order. The pressure-sensitive adhesive sheet 1 for forming a label application region is die-cut to a predetermined size, and is temporarily attached to a mount 10 on which one side has been released. The image 11 is visible through the laminate film 9.

  The transparent release agent layer 8 on the surface of the laminate film 9 is made of a release agent made of a silicone compound, and for example, forms a label application region 8a that can repeat the application and release of another label such as a tag label or a detail label. is doing. The surface of the transparent release agent layer 8 is smooth.

  Next, the usage method of the adhesive sheet 1 for label sticking area | region formation is demonstrated using FIG. 2 and FIG. FIG. 2 is an explanatory diagram of a method for using the pressure-sensitive adhesive sheet 1 for forming a label application region of the present invention, and FIG. 3 is a perspective view showing a container 30 having a label application region. The returnable box shown as the container 30 in FIG. 3 is a rectangular parallelepiped container provided with a lid 31 that can be opened and closed on the upper surface. When there is no content, the container 30 is folded and the container box can be transported in a reduced volume.

  The pressure-sensitive adhesive sheet 1 for forming a label application region of the present invention is used as follows. First, the backing paper 10 is peeled off, and the pressure-sensitive adhesive sheet 1 for label application region formation is attached to the container 30 with the pressure-sensitive adhesive 3 as shown in FIG. Then, as shown in FIG. 3, a label attaching region 8a is formed on the surface of the container 30, and it is possible to freely attach and peel another label without being affected by the smoothness or material of the surface of the container 30. Become. The image 11 printed on the surface of the pressure-sensitive adhesive sheet 4 is visible through the laminate film 9 because all the layers of the laminate film 9 (transparent film 6, transparent adhesive layer 7 and transparent release agent layer 8) are transparent. Is possible.

  As shown in FIG. 2 (a) and FIG. 2 (b), a detailed label 14 composed of a label substrate 12 and an adhesive layer 13 is attached to the label application region 8a as another label. On the surface of the detail label 14, information on the articles stored in the container 30 is printed by a label printer (not shown), and image information 15 such as characters and bar codes is displayed.

  FIG. 3 is a perspective view of a container 30 having a labeling area. The container 30 in the figure is an example in which the label application region forming adhesive sheet 1 is applied to the lid 31 and the side surface of the upper surface of the container 30 to form a label application region. The label application region forming adhesive sheet 1 may be applied to any part of the container 30 to form the label application region 8a. For example, in addition to the top surface, the side surface, and the bottom surface, it can be attached to the inside of the container 30 or the lid 31. The pasting position and the number of sheets may be determined in accordance with the structure of the container 30 and the operation and storage of the stored articles. Only one sheet or a plurality of adhesive sheets 1 for forming the label application area may be applied to the container 30.

  The detail label 14 may be updated after the transportation of the container 30 or when the article to be stored is changed or the storage deadline has passed. In that case, as shown in FIG. 4, the detail label 14 may be peeled off, and another detail label indicating the details of the stored article may be attached. The laminate film 9 that is the surface layer of the pressure-sensitive adhesive sheet 1 for forming the label application region is a tough transparent film 6 provided with a cured film of the transparent release agent layer 8, and has sufficient durability and peelability. The detailed label 14 affixed to the surface can be peeled off smoothly. After the detail label 14 is peeled off, it is possible to repeat the pasting and peeling of another label.

  Thus, since the transparent release agent layer 8 which forms the label application area | region 8a of the adhesive sheet 1 for label application area | region formation of this invention maintains peelability and is further smooth, it repeats sticking and peeling of the specification label 14 repeatedly. However, the adhesive does not adhere or accumulate. Further, the laminate film 9 is not torn when the detail label 14 is peeled off.

  The kind and material of the base material sheet 2 of the pressure-sensitive adhesive sheet 4 constituting the pressure-sensitive adhesive sheet 1 for forming a label attachment region are not particularly limited, such as paper or a synthetic resin film, and are generally used as pressure-sensitive adhesive paper. Can be used. For example, a paper substrate such as fine paper, coated paper, art paper, synthetic resin film made of PET (polyethylene terephthalate), PE (polyethylene), PP (polypropylene), PS (polystyrene), or the above synthetic resin A composite sheet obtained by combining a plurality of types and a synthetic resin film and paper can be used. Synthetic paper such as YUPO (trade name) can also be used. In addition, it is desirable for the base material sheet 2 to have printing suitability in order to print the image 11 such as characters on the surface. Further, depending on the color of the container 30 to be pasted, it is necessary to conceal the container 30 with the base material sheet 2 so that the printed image 11 can be viewed. Therefore, the base material sheet 2 may be opaque or translucent. is necessary. Considering the cleaning operation of the container 30, it is preferable to use a white film having durability and water resistance.

  The pressure-sensitive adhesive of the pressure-sensitive adhesive layer 3 is, for example, a solvent type (a type in which a pressure-sensitive adhesive is dissolved in a solvent), a hot melt type (a type using thermoplasticity), an emulsion type (a type in which a pressure-sensitive adhesive is dispersed in water), or the like. is there. In addition, an ultraviolet curable adhesive, an ultraviolet curable hot melt adhesive, an electron beam curable adhesive, a thermally activated adhesive, and the like can be used. Examples of the material include adhesives such as synthetic rubber, natural rubber, acrylic resin, polyvinyl ether resin, urethane resin, and silicone resin. The adhesive strength of the adhesive is arbitrary, but is desirably 800 gf / 25 mm or more, which is called strong adhesion. The pressure-sensitive adhesive may be selected according to use conditions such as the material of the container 30 and the storage environment.

  As the transparent film 6 constituting the laminate film 9, for example, a synthetic resin film made of PET (polyethylene terephthalate), PE (polyethylene), PP (polypropylene), PS (polystyrene) is used. It is sufficient that the image 11 printed on the base sheet 2 has a transparency that allows the image 11 to be visually recognized.

  The transparent pressure-sensitive adhesive layer 7 includes, for example, a solvent-based pressure-sensitive adhesive, a hot-melt pressure-sensitive adhesive, an emulsion-based pressure-sensitive adhesive, a UV-curable pressure-sensitive adhesive, a UV-curable hot-melt pressure-sensitive adhesive, an electron beam-curable pressure-sensitive adhesive, and a thermal activity. A mold adhesive can be used. Among them, a solvent-based adhesive having a high transparency is suitable, but it may be selected according to the use conditions of the container 30 itself and the storage environment.

  The transparent release agent layer 8 is formed, for example, by applying an ultraviolet curable silicone, a thermosetting silicone, a solvent silicone, an alkyl pendant polymer, or a fluorine-based release agent. As the ultraviolet curable silicone compound, for example, cationic polymerization type, radical polymerization type, radical addition type, hydrosilylation reaction type, addition polymerization type, copolymerization type, and condensation polymerization type can be used. The transparent release agent also needs to be transparent enough to visually recognize the image 11 printed on the base sheet 2.

  The separator 10 is a general purpose one. For example, there may be mentioned paper or film coated with a fluorine-based release agent in addition to ultraviolet curable silicone, thermosetting silicone, solvent silicone, alkyl pendant polymer.

  The type and material of the label and seal that are overlaid as the detail label 14 are not particularly limited, such as paper or synthetic resin film, and those generally used as adhesive paper can be used. For example, paper substrates such as fine paper, coated paper, art paper, thermal paper, synthetic resin films made from PET, PE, PP, PS, film-based thermal paper, and combinations of the above synthetic resins A composite sheet combining a synthetic resin film and paper can also be used. The image information 15 may be printed by any method such as a thermal transfer method (printing using a thermal transfer ribbon), a thermal method (thermal paper), an inkjet method, and a toner method.

  The pressure-sensitive adhesive used for the specification label 14 is also arbitrary, such as an emulsion system, a solvent system, or a hot melt system. What is necessary is just to peel off neatly after the state affixed on the transparent release agent layer 8 is maintained reliably and the role of a statement display is finished.
