Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-shrinkable label, and more particularly to a heat-shrinkable label which is wound tightly around a packaging container by heating or the like.

[0002]

2. Description of the Related Art Generally, a label on which a trade name is printed is wrapped around the surface of a packaging container for various kinds of drinking water, alcoholic beverages and the like. As this label, a heat shrinkable label is often used. This heat shrinkable label
It is composed of a stretched film of polypropylene, polyethylene, polystyrene, vinyl chloride resin, etc., and has a property of shrinking by heating, etc., so that the heat-shrinkable label is wrapped around a packaging container and heated to obtain a heat-shrinkable label. It will be tightly wrapped around the surface of the packaging container.

In recent years, in consideration of the reuse of used packaging containers, as a means for facilitating the peeling of the heat-shrinkable label at the time of recycling, as disclosed in Japanese Utility Model Laid-Open No. 5-16634, the heat-shrinkable label is used. A label provided with perforations of a certain width has been devised. Since the heat-shrinkable label is not glued to the container from the beginning, it can be easily peeled from the packaging container after a part of the label can be cut. That is, in this case, the label can be beautifully and easily peeled from the container without damaging the label at the time of peeling.

However, this heat-shrinkable label is wasteful because it is simply discarded as dust after the peeling, although it can be peeled off from the container beautifully. It is an object of the present invention to avoid wasting the label after being peeled from the container in the “heat-shrinkable label to be wrapped around the body surface of the packaging container”.

[0005]

[Technical Means] A technical means of the present invention for solving the above-mentioned problem is to provide "a back surface of a label (1) made of a transparent resin film capable of enclosing a body surface of a packaging container (2) on its front surface side. From the first printing layer (11), the second printing layer (12) formed by opaque solid printing over the entire upper surface of the first printing layer (11), and the second printing layer (12) A third printing layer (13) which is applied on the label and can be seen from the back side of the label, and a pair of parallel perforations (10) (10) are formed on the label (1).
It was set up between the upper and lower ends. ”

[0006]

The above technical means operates as follows. label
Since the (1) is made of a transparent resin film, the first printing layer (11) formed by printing on the back surface of the (1) is the label (1).
Can be seen through from the front side. Therefore, this first printing layer
The product name etc. given to (11) can be read from the front side.
Next, solid printing is performed on the entire upper surface of the first printing layer (11) to form the second printing layer (12), and the third printing layer (13) is further formed on the upper surface thereof. The third printing layer (13)
Can be read from the back side of the label (1).

This label (1), like the conventional one,
The label (1) is shrunk by heating or the like so that the label (1) is tightly wrapped around the entire circumference of the body of the packaging container (2). From the surface of the label thus wrapped around the container, the first printing layer
Although the above contents of (11) can be confirmed, the contents of the third printing layer (13) cannot be confirmed as they are. Therefore, when the perforations (10) and (10) provided on the label (1) are broken along the perforations, the label (1) is peeled from the packaging container (2), and the label (1) Third printed layer printed on the back side of the
The contents of (13) can be easily confirmed.

Further, since the pair of breaking means are formed in parallel with each other at a constant interval and so as to penetrate the upper and lower ends of the label (1), when the breaking means are broken, the covering The broken pieces are strips having a length that matches the vertical length of the label (1) and a width that matches the interval between the breaking means.

[0009]

[Effect] By forming three printing layers of the first printing layer (11), the second printing layer (12) and the third printing layer (13) on the back surface of one label (1), the label ( Since information can be written on both the front and back sides of 1), the amount of information that can be entered on one label can be increased. Further, since the information written on the front surface side of the label is also printed from the back surface side of the label, there is no inconvenience that the label surface is printed even if an external impact is applied.

To confirm the information printed on the back side, the label (1) is broken by breaking the perforations of the label (1).
Since it can be easily peeled off from the packaging container (2), the information written on the back surface of the label (1) can be easily confirmed. Further, since the fragment to be formed by breaking the perforation is formed into a constant strip shape, the strip is used as an application ticket when a prize is planned for the product. be able to.

Further, when the packaging container (2) is collected and recycled, the label (1) is, as described above, the packaging container (2).
The label (1) and the packaging container (2) at the time of recycling can be smoothly separated because they can be easily peeled off.

[0012]

Embodiments of the present invention described above will now be described in detail with reference to the drawings. The container (2) around which the heat-shrinkable label of the embodiment of the present invention is wrapped is a glass bottle having a cylindrical body as shown in FIG. 1, and a transparent film made of vinyl chloride resin is provided on the body. The heat-shrinkable label (1) consisting of is wound around.

This one sheet of heat-shrinkable label has a three-layer printing on the back side of the label (1) which is formed in a cylindrical shape having a size just surrounding the cylindrical body of the packaging container (2). And 2
The procedure for producing such a heat-shrinkable label for forming perforations (10) (10) of a book will be described below. First, a strip-shaped sheet (3) made of a transparent continuous film wound into a roll is prepared. The width of this strip (3) is
Approximately 1 cm longer than the outer circumference of the cylindrical body of the packaging container (2)
Set it for a long time. The extension area (30) of about 1 cm serves as a glue margin when the strip-shaped sheet (3) is rolled later.

The strip-shaped sheet (3) is unwound and pulled out, and as shown in FIG. 2 (a), in the first printing step (31), the extension region (30) is formed on the upper surface side of the strip-shaped sheet (3). The first printing layer (11) is formed at predetermined intervals in the range excluding (). The contents of the first printing layer (11) are set so that they can be confirmed when seen through from the lower surface of the strip-shaped sheet (3).
Then, in the second printing step (32), the first printing layer (1
Solid printing is performed on the printing area of 1) to form the second printing layer (12), and at the next third printing step (33), predetermined printing is performed on the second printing layer (12). Apply the third printing layer (1
3) is formed. The contents of the third printed layer (13) can be confirmed from the upper surface of the strip-shaped sheet (3).

As shown in FIG. 2B, the strip-shaped sheet (3) thus formed with the three printing layers is placed in the next back-applying device (34) with the above-mentioned printing layers inside and the strip-shaped sheet (3). (3) is wound in a tubular shape along its long side to form a tubular body having a size that surrounds the body of the packaging container (2). This back-adhesion processing is performed by a back-adhesion machine provided separately from the printing process, as shown in FIG. 3, while applying perforations while applying the adhesive to the extension areas (30) formed along the side edges. Then, the adhesive-applied portion is rolled into a tubular shape so as to overlap with the area near the other side and finished. Incidentally, the perforation (10) (10) forming area may be any area other than the side vicinity area which overlaps when the belt-shaped sheet (3) is formed into a cylindrical shape, but in this embodiment, this overlapping part It is formed along the outside of.

Finally, in the cutting step (35) of FIG. 2 (c), if the sheet is cut for each of the printing layer forming regions, printing is performed on the back surface as shown in FIG. label
(1) will be completed. At this time, it is also possible to cover the container while cutting with a label mounting machine.
When the label (1) fitted on the container (2) is shrunk by heating or the like, it can be tightly wound around the body of the container (2). Since this label is composed of a transparent resin film, the first printed layer (11) printed first on the back side of the label
The contents of can be read from the label surface side. On the other hand, the contents of the third printing layer (13) appearing on the back surface of the label can be easily obtained by breaking the perforations (10) (10) and peeling the label (1) from the container (2). You can check it.

In the label (1) of this embodiment, the first printing layer is
As for the contents of (11), it is preferable to be able to confirm general items such as product name, manufacturer name, raw material name, etc., as well as general labels, as well as information indicating that a prize is awarded.
As the content of the print layer (13), it is conceivable to print out the application procedure of the prize. In this case, perforation (1
There is no waste if the broken pieces (15) that are broken from the label (1) by (0) and (10) are used as application tickets.

It is also possible to partially scratch print the third printing layer (13). In this case, if information such as "hit" or "off" is hidden under the scratch printing, it can be used as a lottery label. The color of the ink used for the second printing layer (12) for solid printing is not particularly specified as long as the color of the ink used for the third printing layer (13) can be seen.
