Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminated label, and more particularly, to a laminated label which can be easily peeled at a portion to be peeled.

[0002]

2. Description of the Related Art A label is described on a postcard, for example, in which an adhesive surface when a label substrate is adhered to an adherend and a release surface when the label substrate is peeled from the adherend are different. It is used for various purposes such as hiding information.

[0003] By the way, a delivery slip is used to surely deliver the goods of a department store or the parcels delivered by a shipping company to a destination. As this type of delivery slip, a slip in which a plurality of pressure-sensitive copy papers are stacked is widely used. However, in this delivery slip, it is not possible to clearly write down to the bottom slip unless strong pressure is applied when writing an address or the like, so a ballpoint pen or an impact printer has to be used. Therefore, it takes a long time to fill out a slip, and it is desired that a department store or the like handling a large amount of luggage in a short period of time speed up issuance of a delivery slip.

[0004] In view of such demands from the market and the flow of digitization of customer data, Japanese Patent Application Laid-Open No. H11-28875 has proposed a delivery slip that can use a non-impact printer capable of high-speed printing. This delivery slip is an application of the concept of the label described above. According to this delivery slip, a non-impact printer can be used, and the delivery slip can be issued in a short time. In addition, the delivery person peeled off the receipt receipt part which was quasi-adhered to the delivery slip, received a seal as confirmation of receipt of the package, and returned the receipt receipt and kept it. However, in a state where the above-mentioned delivery slip is attached to the package, there is no trigger part for peeling, and it often takes time to peel off the receipt part from the delivery slip. In a concealed postcard or the like, the base material is flexible, so that the postcard can be easily peeled off by bending the postcard. However, in the case of a luggage (box), practical use was difficult without an opportunity.

Therefore, a delivery slip 90 shown in FIG. 4 and FIG. 5, which is a sectional view taken along the line BB of FIG. 4, has been proposed. The delivery slip 90 includes a peelable portion 91 that is a receipt certificate portion and a non-peelable portion 92 that is a destination display portion. The peelable portion 91 has a release layer 94,
A resin layer 95, an adhesive layer 96, and a release sheet 97 are sequentially laminated. Further, the non-peelable portion 92 is separated from the peelable portion 9.
The structure is different from the structure of FIG. 1 in that the release layer 94 is omitted. The release trigger 98 of the delivery slip 90 is provided at the end of the peelable portion by not forming the resin layer 95 and the adhesive layer 96.

In the delivery slip 90, since the adhesive layer 96 having a width smaller than the width of the base material 93 is provided, an adhesive is applied to the release sheet 97 to form the adhesive layer 96, and then the resin layer of the delivery slip 90 is formed. By laminating a release sheet 97 with an adhesive layer 96 on 95, a delivery slip 90 can be created. At this time, the adhesive layer 96 is slightly pushed inward even at the right end in the drawing of the delivery slip so that the adhesive does not protrude.

When the delivery slip 90 is used, the release sheet 97 is peeled off while holding the peeling trigger 98 and the adhesive layer 96 is exposed, and the delivery slip 90 is attached to the package by the adhesive layer 96. . When the peelable portion 91, which is the receipt section, is peeled off, the receipt section can be easily peeled off from the delivery slip 90 by peeling it off with the peeling trigger 98.

[0008]

However, since it is difficult to accurately coat a high-viscosity substance such as an adhesive in an intermittent pattern, the peelable portion 91 is difficult.
If the non-peelable part 92 and the non-peelable part 92 are provided side by side in the flow direction at the time of manufacturing, as shown in FIG. As a result, the delivery slip 90 may fall off.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a laminated label which can prevent the label from accidentally falling off and can easily peel off the base material of the label when intended.

[0010]

In order to achieve the above object, a laminated label according to the present invention comprises a laminated label in which a release layer, a resin layer, an adhesive layer, and a release sheet are sequentially laminated on the back side of a substrate. In, the adhesive force between the release layer and the resin layer is partially different, the adhesive force between the release layer and the resin layer, a strong adhesive portion larger than the adhesive force between the adhesive layer and the release sheet,
By having a weak adhesive portion where the adhesive force between the release layer and the resin layer is smaller than the adhesive force between the adhesive layer and the release sheet, when peeling off the label from the release sheet, the adhesion of the weak adhesive portion The layer and the resin layer can be left on the release sheet. Further, the adhesive force between the base material and the release layer is larger than the adhesive force between the release layer and the resin layer in the strongly bonded portion,
If the adhesive force between the resin layer and the adhesive layer is larger than the adhesive force between the release layer and the resin layer in the strongly bonded portion, it is possible to reliably peel off between the release layer and the resin layer. it can.
Furthermore, if at least a part of the weakly adhered portion is located at the peripheral edge of the peelable portion of the laminated label, it is easy to grasp the trigger portion of peeling. In addition, in the weakly adhesive part and / or in the vicinity thereof,
By providing a half cut that at least reaches the release layer from the resin layer and does not penetrate the base material, when peeling the label from the release sheet, the adhesive layer and the resin layer of the weakly adhesive portion can be reliably left on the release sheet. . Further, the release layer may be formed only on a part of the substrate.
