Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a postcard in which a concealment label is attached to the surface of a postcard in order to conceal and protect personal information on the surface of the postcard.

[0002]

[Prior art]

 Recently, automatic account transfers such as health charges, electricity and telephone charges have become popular, and along with this, it has been carried out to send a notice of transfer, which describes the amount of the transfer, etc., by a postcard with low postage. ing. To protect this personal information (privacy), a label called a secret label is attached to the part where the personal information is written.

[0003] This label completely protects and conceals the surface of the postcard when mailed, and the recipient can see the contents on the surface of the postcard only after peeling off the label. As shown in FIG. 5, a film (103) made of polyethylene or the like is laminated on the lower side of the paper (101) and the aluminum foil (102), and further extruded under this temperature adjusted to a temperature at which the film (103) is not completely adhered. In addition, a transparent film (104) such as polyester is laminated, a pressure sensitive adhesive (105) is applied under the transparent film (104), and the film is covered with a release paper (106).

Then, at the time of use, the release paper (106) is peeled off, and the postcard on which personal information (having privacy) is displayed is attached by a pressure-sensitive adhesive (105) so as to cover at least this display portion. Put on. In this state, since the aluminum foil (102) exists, the surface of the postcard can be concealed because the aluminum foil does not pass light even when the postcard is viewed through the light in the usual case. It will be mailed as it is. When the recipient peels off the label, it peels between the film (103) and the transparent film (104), and the transparent film (104) remains on the postcard so that the film (104) is not sticky. Because it is transparent, the contents displayed on the postcard can be read.

In addition, two perforations (107) penetrating the paper (101), the aluminum foil (102) and the film (103) are provided, and the width is slightly wider than the width of the two perforations (107). A stripping varnish having a width is provided between the film (103) and the transparent film (104). This is to peel off the perforation (107) portion when peeling off the label so that the adjacent portion can be easily rolled up and peeled off.

[0006]

[Problems to be solved by the device]

 Since the above-mentioned conventional label has a structure in which it peels between the two kinds of films, it does not fall off from the postcard during mailing, and when the recipient peels off the label, it does not damage the surface of the postcard. In order to separate between the films, there is a problem that a sophisticated technique is required to control the temperature at which the synthetic resin forming the film (104) is extruded, and the apparatus is also large-scale. Moreover, since aluminum foil is used for concealment, the cost is high, and it is not preferable because it cannot be incinerated for disposal.

[0007]

[Means for Solving the Problems]

 In view of the above problems, the present invention uses a concealment label that uses a concealment label that does not use a peeling surface between two types of synthetic resin films, but forms a peeling surface using a printing processing technique to facilitate processing. It is a postcard with a label.

As a constitution, it is formed by sequentially laminating a base material mainly made of a paper having a concealing property, a transparent ink layer having poor adhesiveness, a pressure-sensitive adhesive layer, and a release paper. A postcard with a concealment label, which is a concealment label that can be peeled between a material and the transparent ink layer, and which is peeled off from the release paper and attached to the display portion of the postcard with the pressure-sensitive adhesive layer.

[0009]

According to the postcard with the concealment label of the present invention, when the release paper of the concealment label is peeled off and attached to the display portion of the postcard with a pressure-sensitive adhesive, the postcard is displayed by the concealing base material. The content is completely hidden. If you try to remove the concealment label from the postcard, it will peel off between the base material and the transparent ink layer because the adhesiveness of the transparent ink layer is poor, and this peeled surface will be completely dried because it is formed with the ink layer. Since it does not adhere to itself again, it cannot be restored to its original state, and the trace of opening will be apparent.

[0010]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example of a concealment label. In order to impart concealment to the base material (1), solid ink is printed on the back surface of the base material (1) made of paper or the like. To form a black ink layer (2), and the transparent ink layer (3) having poor adhesiveness is printed on the lower surface of the black ink layer (2) to form the transparent ink layer (3). The transparent ink layer (3) is formed, then the pressure sensitive adhesive (4) is applied to the lower surface of the transparent ink layer (3), and the transparent ink layer (3) is covered with a release paper (5).

The release paper (5) coated with a pressure-sensitive adhesive in advance and dried may be attached so as to face the transparent ink layer (3) side of the base material (1).

Next, a method of using the postcard with the concealment label is shown in FIG. First, the release paper (5) of the concealment label is peeled off, and the pressure sensitive adhesive is applied so as to cover the display portion (6) of the postcard (7) and mailed. As long as the label is not peeled off, the display part (6) is completely hidden, and even if the postcard is seen through the light, the black ink layer (2) does not pass through the light and thus cannot be seen through.

When the recipient peels off the label, a separation surface is formed between the black ink layer (2) and the transparent ink layer (3), and as shown in FIG. 3, the base material (1) and the black ink layer (2) It is possible to read the hidden display part (6) through the transparent ink layer (3) and the pressure-sensitive adhesive layer (4). At this time, the transparent ink layer (3) is completely dry and does not have adhesiveness (viscosity), which is convenient for storing postcards.

Further, even if it is illegally opened, it is impossible to attach it again between the black ink layer (2) and the transparent ink layer (3), and if the original state is restored. Since the trace remains, it is effective in preventing unauthorized opening.

FIG. 4 shows another embodiment of the concealment label, which includes a substrate (1), a black ink layer (2), a transparent ink layer (3), a pressure-sensitive adhesive layer (4) and a release paper (5). ) Are laminated in order, the basic structure up to this point is the same as that of the embodiment of FIG. 1, and in this embodiment, the black ink layer (2) is formed on the back surface of the substrate (1). ) Are laminated to form perforations (8) having a desired width, and then a release agent (9) having a wider width than the perforations (8) is spot-printed on the lower surface of the black ink layer (2). It was done. The perforation (8) and the release agent (9) serve as a trigger for facilitating peeling on the peeling surface (p).

The black ink layer (2) used in the present invention for enhancing the hiding property is composed of a pigment of any color, a resin binder, a solvent, and other additives (such as tackifier). Polyamide-based, chlorinated rubber-based, urethane-based, nitrified cotton, vinyl chloride acetate-based, chlorinated PP-based, etc. can be used, or fatty amide or silicon-based etc. can be added to these to adjust for easy peeling. The thickness of the layer is preferably in the range of 0.5 to 5 μm.

The transparent ink layer (3) is also composed of a resin binder, a solvent, and other additives (such as tackifier), and the adhesiveness to the black ink layer (2) is not good. It is generally called OP varnish. It uses nitrified cotton, polyamide system, chlorinated rubber system, urethane system, vinyl chloride system, chlorinated PP system, curable urethane system, phenol system, melamine alkyd system, epoxy system, etc. Alternatively, a fatty amide, a silicone or the like may be added to these for easy adjustment, and the layer thickness is preferably in the range of 0.5 to 5 μm.

In order to reduce the adhesive force between the black ink layer (2) and the transparent ink layer (3) among the above-mentioned types of ink, as described above, either black ink or transparent ink is used. It is also effective to add and use a fatty amide or a silicon-based component to one or both of them, and also to use the resin binder and solvent contained in the black ink layer and the resin binder contained in the transparent ink layer. It is also preferable to select a combination in which the solvent and the solvent are mutually insoluble. Specifically, rubber chloride type is selected as the black ink layer (2) and nitrified cotton + polyamide type is used as the transparent ink layer (3). When selected and manufactured, very good results were obtained.
