[0002]

2. Description of the Related Art In general, a label on which a picture, an advertisement character or the like is printed is attached in a belly shape on the side surface of a cup-shaped container for sake. By the way, conventionally, in such a label, it is usual to print a pattern or the like only on the surface thereof, but not only the surface but also the surface (the back surface) on the side in contact with the container is printed. It is also practiced to allow consumers to enjoy the pictures on both sides of the label. Moreover, for example, Japanese Utility Model Publication No. 42-11377 and Japanese Utility Model Publication No. 1-162.
As described in Japanese Unexamined Patent Publication No. 375, etc., when two or more labels are removably superposed and the upper label is peeled off, for example, a lottery ticket, various information, a lower label on which a pattern or the like is printed Those whose surface is exposed are also generally known. In this way, for example, in a label in which two labels are overlapped (a so-called double label), it is possible to print a maximum of four times as much information as a normal label whose front surface is a printing surface. ..

[0003]

In the double label as described above, when printing the front and back surfaces of the lower label and the upper label, the space between the upper and lower labels and the front and back surfaces of the respective labels are It is necessary to match the registration of the design. However, when manufacturing such double labels, the method of printing on the front and back surfaces of the original fabric of each label and then simply adhering (temporarily attaching) them and cutting them into pieces is There is a problem that registration is very difficult and the manufacturing process is complicated.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a label which can simplify the manufacturing process and can be easily registered, and a manufacturing method thereof. To do.

FIG. 4 is a plan view of the original fabric of the label in the embodiment, FIG. 5 is a layer configuration diagram of the original fabric viewed from the direction B of FIG. 4, and FIG. 6 is the original fabric of the same embodiment. Is a half-folded and bonded state, and FIG. 7 is a schematic configuration diagram of a bag-making machine used for manufacturing the label of the embodiment.

The label 1 of this embodiment is used by being attached to the side surface of a cup-shaped container for sake.
As shown in FIG. 2, tabs 2 are formed in an arc shape in a substantially rectangular shape at a substantially central portion of one short side, and two perforated lines are formed above and below the tab 2 at a predetermined interval in parallel with the long side. 3,3
Are formed.

The label 1 is manufactured as follows. First, an ink layer 5 is formed by gravure printing on both sides of a base material layer 4 composed of both art papers (basis weight 84.9 g / m ² ).
a and 5b are provided, and a release agent layer 6 is partially provided on the front surface of the ink layer 5b on the back half surface.
A thermoplastic resin layer 7 made of polyethylene (PE ¹⁵ ) is provided on the entire surface on the side where the release agent layer 6 is provided by extrusion using an EC machine to obtain a laminate 8 as shown in FIG. Next, as shown in FIG. 6, the laminate 8 is cut and half-folded so that the release agent layer 6 is on the inner side (the half-folded position is shown by a chain line in FIG. 5), and perforations are formed at required portions. And heat-seal the opposite surfaces together, and then
A small piece is cut at the position indicated by the alternate long and short dash line in FIG. 4, and further die-cut into the shape of the label 1 indicated by the alternate long and two short dashes line in the figure.

Here, as the release agent constituting the release agent layer 6, for example, a mixture of medium (NC + urethane) manufactured by Showa Ink Co., Ltd. and a silicone type release agent is used, and its application pattern is shown in FIG. As indicated by the diagonal lines, the width is parallel to the long side of the label 1 and slightly wider than the width between the perforations 3 and 3.

Further, the steps of cutting, half-folding, perforating, heat-sealing and shredding the laminated body 8 are performed in-line using a bag-making machine 9 as shown in FIG. This bag-making machine 9 is a known bag-making machine modified so that the width of the seal bar 10 is widened to, for example, about 100 mm. The laminated body 8 wound in a roll shape is the laminated body 8.
Is cut and separated into two parts 8a and 8b by a cutter 11 provided at the center in the width direction of each part.
a and 8b are guided upward and downward, respectively, and are changed in direction by the guide rollers 12a and 12b respectively arranged above and below, and then superposed at the positions of the two guide rollers 13a and 13b arranged in the central portion. Be done. Next, the laminated body 8 thus superposed is entirely transferred by the seal bars 10 provided above and below the guide rollers 13a and 13b while being intermittently transferred. Although not shown in the drawing, a perforation inserting device is arranged at a required position between the cutter 11 and the guide rollers 13a and 13b on the downstream side, and a downstream side of the seal bars 10 and 10 is provided. A cutting device for shredding is arranged.

The label 1 having the above structure is attached to the side surface of the cup-shaped container with the upper surface of the label 1 facing upward in FIG. In this state, the consumer can see the pattern of the outermost ink layer 5a and the like, and also see the pattern of the outermost ink layer 5a from the back side through the transparent container side wall and the sake inside. Further, when the tab 2 at the edge of the base material layer 4 on the upper side of the label 1 is pinched and peeled off, the release agent layer 6 and the thermoplastic resin layer 7 are in a weakly adhered state at the portion where the release agent layer 6 is provided. ,
Since the other portions are in a strong adhesive state, the label 1 tends to be separated into the upper label 1a and the lower label 1b at the interface between the release agent layer 6 and the thermoplastic resin layer 7. At this time, since the perforations 3, 3 are provided slightly inside the edge of the release agent application portion, the upper label 1a is triggered by the perforations 3, 3 as shown by the chain double-dashed line in FIG. It peels off from the label 1b, whereby the patterns of the respective ink layers 5a and 5b on the back surface of the upper label 1a and the surface of the lower label 1b appear.

In the above embodiments, the thermoplastic resin layer was formed by extrusion coating of polyethylene, but in addition to the above, it may be formed by applying a hot melt adhesive or a heat sealing agent. The same effect can be obtained.

Further, the surface of the base material layer on the thermoplastic resin layer side may be previously subjected to corona discharge treatment.

An extruded coating layer of the thermoplastic resin layer 31 is provided to obtain a laminated body 32 as shown in FIG.
As shown in FIG. 13, the thermoplastic resin layer 31 is cut and half-folded so as to come to the inside, and perforations are formed at required portions to heat-seal the opposing surfaces, and then cut and die-cut. ing. Here, as the film forming the outermost layer of the base material layer 28, for example, stretched polypropylene (OPP) or stretched nylon (ON) may be used in addition to PET. Note that, in FIG. 12, the alternate long and short dash line indicates the half-folded position.

In each of the above-mentioned embodiments, two perforations that trigger the peeling of the upper label are provided, and the pattern of the release agent layer (or anchor coating agent layer) is formed.
As shown in FIG. 3, the description has been given of the case where the two perforations are set in a shaded portion (or outside of the shaded portion) surrounded by two straight lines set slightly outside.
The formation pattern of the perforations and the release agent layer is not limited to this, and various other modifications are possible. 14 to 16 show this modification.

In the label 1A shown in FIG. 14, the perforation 3
