Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a label that can be stored as is after being pasted and used.

(Prior Art) Conventionally, labels are known which are composed of an adhesion base material having an adhesive layer on the back surface to be adhered to an adherend, and a label body which is releasably polymerized and adhered to the upper surface of the base material via an adhesive. It is.

(Problem to be solved by the invention) After the conventional label is pasted and used, it can be peeled off from the bottom layer of the pasting base material in order to preserve only the label body if necessary, but the back side has adhesive. Since the drug layer is attached, it cannot be stored as is, and it is necessary to paste it onto a separately prepared storage sheet and store it, which is troublesome and uneconomical. In order to eliminate this drawback, the applicant first filed Utility Application No. 58-186890.
I proposed an idea for the issue. In this invention, a self-adhesive processed surface, that is, a weakly adhesive coating film, is applied to either the facing surface of the molded plastic film sheet provided on the back side of the label body and the molded plastic film sheet that is the adhesive base material. When applied, they are weakly polymerized and bonded to each other so that they can be peeled off freely, and their manufacture is troublesome and expensive.

(Means for Solving the Problems) The present invention eliminates the above-mentioned conventional drawbacks and provides a label that is easier to manufacture and can be obtained at lower cost than the previously proposed device. In a label formed by polymerizing a pasting base material having an adhesive layer on the back side to be pasted on the back side and a label body having an adhesive layer on the top surface of the label body, the pasting base material is a synthetic resin coating film or It is composed of a molded sheet, and an intermediate base material made of a synthetic resin coating or a molded sheet is interposed between the pasting base material and the adhesive layer of the label body on the upper surface thereof, and the pasting base material and the intermediate base material and at least one of them as a coating film, and are closely bonded directly to each other without the intervention of an adhesive.

(Example) Next, an example of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an example of its implementation, and numeral 1 indicates an adhesion base material made of a molded sheet of synthetic resin film having an adhesive layer 2 to be adhered to an adherend. 3
is a sheet-like sheet made of synthetic resin, metal foil, paper, etc., which has an appropriate printed display area 3a such as letters, figures, patterns, etc. on the front side and has an adhesive layer 4 mainly made of rubber or synthetic resin on the back side. Indicates the label body.
According to the present invention, in the label of the type in which the label body 3 and the pasting base material 1 are polymerized, there is a gap between the lower surface of the adhesive layer 4 of the label body 3 and the upper surface of the pasting base material 1. For example, an intermediate base material 5 made of a transparent or opaque synthetic resin coating is interposed on the upper surface of the adhesive base material 1, and the intermediate base material 5 and the adhesive base material 1 are
The label of the present invention is constructed by directly and tightly joining each other without using an adhesive. 6 shows a release paper temporarily attached to the outer surface of the adhesive layer 2 until use.

The above label is manufactured, for example, as follows. An adhesive is applied to the back side of the label body 3 to form an adhesive layer 4, while an adhesive is applied to one side of the adhesive base material 1 to form an adhesive layer 2, and the adhesive A release paper 6 is temporarily attached to the outer surface of the layer 2, and a coating liquid containing a synthetic resin dissolved in an organic solvent is applied to one surface by a casting method and dried, or the synthetic resin is heated and melted by an extrusion method. The intermediate base material 5 consisting of an intermediate coating film of the synthetic resin is formed by applying the resin in a thin film-like manner.
Next, the above-mentioned sticking base material 1 is formed on the adhesive layer 4 side of the above-mentioned label body 3 by polymerizing the intermediate base material 5, that is, the coated surface thereof.

In addition, instead of forming the coating film 5 which is the intermediate base material 5 in the above production method on the side of the first surface of the adhering base material,
It may be formed in advance on the four surfaces of the adhesive layer of the label body 3.

In the label of the present invention constructed in this way, the adhesive force between the intermediate base material 5 and the adhesion base material 1 on the lower surface thereof is equal to the adhesive force between the label body 3 and the adhesive layer 4,
The adhesive force between the adhesive layer 4 and the intermediate base material 5, the adhesive force between the adhesive base material 1 and the adhesive layer 2, and the adhesive force between the adhesive layer 2 and the adherend. is also set to be the weakest.

Thus, as shown in the second figure, when the label body 3 is picked up and pulled up after being attached to the surface of the adherend 7, the intermediate base material 5 and the first layer of the adhesion base material are separated. As a result, it can be easily peeled off and removed from the adherend 7.

In FIG. 3, the adhesion base material 1 is formed from a synthetic resin coating film instead of a molded sheet, and the intermediate base material 5 is formed from a synthetic resin molded sheet instead of the coating film, and other configurations are shown. is the same as the embodiment shown in FIG. The synthetic resin materials of the adhesion base material 1 and the intermediate base material 5 may be the same or different from each other, such as low-molecular polyester resin, ethylene-vinyl acetate resin, high-molecular polyester resin, and vinyl chloride resin. Consists of etc. Further, both of the base materials 1 and 5 can be formed of a coating film.

Thus, in the labels of the present invention shown in FIGS. 1 and 3, when the label body 3 is peeled off from the adherend 7, the outer surface of the adhesive layer 4 on the back side is made of a synthetic resin coating or a molded sheet. Since the label body 3 covered with the intermediate base material 5 is obtained, it can be stored immediately as it is, and the trouble and waste of pasting it on a storage sheet and storing it as in the past can be avoided.

In this case, in order to utilize the peeled label more effectively, as shown in the embodiments shown in the first and third figures, the back side of the label body 3 or the intermediate base material 5 is used.
A printed display section 8 for drawing lots, collecting animals, or other arbitrary designs is provided on the inner surface of the display device, and the adhesive layer 4 and the intermediate substrate 5 on the lower surface thereof are made of a transparent material. In such a case, the transparent adhesive layer 4 and the intermediate base material 5 are placed on the back side of the peeled label.
The display portion 8 can be observed through the label and used as a lottery label or a label for collecting animals, etc., increasing the utility value of the label. Further, since the display section is protected from the outside world by the intermediate base material 5, the printed display section 8 is not damaged and can be used and stored stably. FIG. 4 shows an additional intermediate base material 5' consisting of an additional transparent coating film to make it easier to place the printed display part 8, an adhesive layer 4, and a comparatively printed display part 8.
A double intermediate base material may be provided including the intermediate base material 5 which is difficult to ride on. In this case, even if the peeling is performed between both intermediate base materials 5', 5, the same above-mentioned objective can be achieved.

Example 1 An acrylic adhesive was applied to the back side of a label body made of high-quality paper and dried.
A synthetic resin made of low-molecular polyester resin is coated on one side of the base material for adhesion of a molded sheet made of polypropylene film with a thickness of 25 μm and dried to form an intermediate base material made of a coating film with a thickness of 20 μm, and an acrylic resin is applied on the other side. The adhesive is applied and dried to form an adhesive layer, and the intermediate base material is polymerized on the underside of the adhesive layer of the label body to form a label, which is then immediately attached to the adherend. After pasting with the adhesive layer, when the label body is pulled off with a pinch, the adhesive layer and the intermediate base material are peeled off on the lower surface, and the label body remains as it is with the intermediate base material covered with adhesive. It was confirmed that it can be saved.

Example 2 A label body was prepared in the same manner as in Example 1 above, and an adhesive layer made of an acrylic adhesive was applied and dried on one side of a sticking base material made of a polyethylene phthalate film with a thickness of 50 μm, A release paper is provided on the lower surface of the adhesive layer, while an intermediate base material consisting of a 15 μm thick coating film is formed on the other surface of ethylene-vinyl sulfate resin using the extrusion method, and furthermore, a layer for printing is applied on the adhesive layer. An additional intermediate base material consisting of a 3 μm thick coating of polyester (trade name) manufactured by Nippon Gosei Kagaku Co., Ltd., which is suitable for The label was constructed by polymerizing the label body with the adhesive layer on the lower side and the intermediate base material side. After this label was affixed to an adherend, when the label body was peeled off, the adhesive layer on the back side was polymerized on the intermediate base material side. A label coated with the base material was separated, and the display part could be seen on the back side through the adhesive layer and the intermediate base material.

As described above, according to the present invention, a label is formed by polymerizing a label body having an adhesive coating layer on the back side and an adhesive base material having an adhesive layer on the back side to be attached to an adherend. Polymerization is performed via an intermediate base material consisting of a synthetic resin coating or a molded sheet between the label body and the base material for attachment, without using an adhesive between the intermediate base material and the base material for attachment. Since the label is tightly bonded, when the label body is peeled off after being attached to an adherend, there is an adhesive layer on the back side and an intermediate base material that polymerizes on the back side and covers it. Since it can be peeled off, it can be stored as is in a storage container, etc., without requiring a storage sheet like conventional methods, and the label body is reinforced by the intermediate base material on the back, allowing for safe storage. It has the effect of
