Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a multiplex label laminated so that an outer label is peeled off from an inner label, a long laminate film for the multiplex label, and a manufacturing method thereof.
[0002]
[Prior art]
Conventionally, various double labels are used mainly for the purpose of enlarging the display area (the following Patent Document 1), and there are double labels in which both inner and outer labels having a display portion are adhered to each other by an adhesive. A perforation (cutting line) is formed in a predetermined portion of the outer label to peel off the outer label, and the outer label is peeled off from the inner label by cutting the perforation and shielded by the outer label. The display part of the inner label becomes visible.
[0003]
If the perforation is formed after laminating the inner and outer labels, a perforation is also formed on the inner label. When the perforation is cut, the inner label is also cut at the same time, and the outer label is well separated from the inner label. I can't. Therefore, perforations are formed in advance only on the outer label before lamination, and the outer label with the perforation is laminated on the inner label.
[0004]
In this way, both the inner and outer labels are releasably adhered by the applied adhesive, but from the viewpoint of manufacturing such as control of adhesive force control and production speed, and in the case of adhesive From the standpoint that the force required to peel off the label tends to vary, we have developed a double label that uses an adhesive film instead of an adhesive. In the double label, an adhesive film is interposed between the outer label and the inner label, and the adhesive film and the inner label are pseudo-bonded. In other words, the outer label and the adhesive film are integrally peeled off from the inner label, and after the peeling, the adhesive film does not remain on the surface of the inner label, so the display portion of the inner label is clearly displayed. The

[Problems to be solved by the invention]
In the above-mentioned double label, the outer label and the adhesive film can be pseudo-adhered. However, since the adhesive film is generally soft and inferior in wear resistance, if it remains outside the inner label without being peeled, Is likely to occur. Therefore, the adhesive film and the inner label are pseudo-bonded so that the adhesive film does not remain on the surface after peeling.
[0007]
However, in the case of a double label in which both inner and outer labels are laminated with an adhesive film, it is not easy to cut the outer label together with the adhesive film because the adhesive film has no perforation.
[0008]
Therefore, the present invention is easy to manufacture, has little variation in the force required for peeling off the outer label, and can easily cut a predetermined portion of the outer label. It is an object of the present invention to provide a manufacturing method thereof.
[0009]
[Means for Solving the Problems]
The present invention has been made to solve the above problems, and the multiple label according to the present invention is a multiple label in which the outer label is peeled off from the inner label, and the outer label and the inner label are different from the outer label. It is laminated via an adhesive film so that peeling occurs on the surface of the inner label at the time of peeling, and the outer label and the adhesive film are cut in a lump without leaving the inner label at a predetermined position of the outer label and the adhesive film. A cutting line is formed for this purpose.
[0010]
In the multi-label having such a configuration, both the inner and outer labels are bonded via an adhesive film, so that an adhesive is not required and can be easily manufactured, and an adhesive film is used. There is also little variation in the force required for peeling between multiple labels. And since the cutting line is formed in the adhesive film and the outer label, the predetermined portion of the outer label can be easily cut together with the adhesive film.
[0011]
Moreover, the long laminate film for multiple labels according to the present invention is a long laminate film for multiple labels in which the outer label is peeled off from the inner label, and the first elongated film and the inner label serving as the outer label, The second long film is laminated via a long adhesive film so that peeling occurs on the surface of the inner label when the outer label is peeled off, and the first long film and the adhesive film are placed at predetermined positions. Is characterized in that a cutting line for collectively cutting the outer label and the adhesive film while leaving the inner label without being cut is formed along the longitudinal direction of the long laminate film.
[0012]
In the long laminate film having such a configuration, since the first and second long films are laminated through the adhesive film, the production thereof is easier than in the case of using an adhesive. Moreover, although a multiple label can be manufactured by cutting or punching a long laminate film, the outer label and the inner label are laminated via an adhesive film, which is necessary when peeling the outer label. It is suppressed that the force varies for each of the multiple labels. Furthermore, since a cutting line for cutting the outer label and the adhesive film in a lump is formed along the longitudinal direction, a predetermined portion of the outer label is bonded to the multiple label manufactured from the long laminate film. Can be easily cut with the film.
[0013]
Furthermore, the method for producing a long laminate film according to the present invention is a method for producing a long laminate film for a multi-label described above, and the first method is to cut the fed raw film along its longitudinal direction. After a long film and a second long film are formed, a long adhesive film is overlapped on the back surface of the first long film, and a cutting line is collectively formed along the longitudinal direction on the both. The second long film is overlaid on the back surface of the adhesive film, and the first long film and the adhesive film are laminated so as not to be peeled off, and the adhesive film and the second long film can be peeled off. It is characterized by being laminated.
[0014]
According to this method, the first and second long films are formed from a single raw film, and the long adhesive film is overlapped on the back surface of the first long film, and a cutting line is formed on both of them. And then the second long film is peelably laminated so that only the first long film and the long adhesive film can be formed without forming a cutting line on the second long film. A cutting line can be easily formed. In addition, since it is performed in a series of steps from one raw film to production of a long laminate film, both long films are compared with the configuration in which the first and second long films are fed out from separate raw rolls. However, it becomes difficult to shift the position particularly in the longitudinal direction, and a long laminate film for multiple labels laminated with high accuracy can be easily produced.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a multiple label according to the present invention, a long laminate film for the multiple label, and a method for producing the same will be described with reference to the drawings.
FIG. 1 shows a double label in the present embodiment. The double label 1 is formed in a cylindrical shape by laminating and adhering left and right end portions of a single laminate film, and contracts mainly in the circumferential direction by applying heat. It is. The overlapping portion 2 is formed along the vertical direction (axial direction). In FIGS. 1 and 4, the overlapping portion 2 is hatched.
[0016]
As shown in FIG. 3, the double label 1 is formed by laminating an outer label 3 and an inner label 4 by thermocompression bonding via an adhesive film 5, and the outer label 3 and the adhesive film 5 are anchor coats. The adhesive film 5 and the inner label 4 are laminated so as to be peelable. Accordingly, when the outer label 3 is peeled, peeling occurs between the adhesive film 5 and the inner label 4, and the adhesive film 5 is peeled together with the outer label 3.
[0017]
The outer label 3 and the inner label 4 are each provided with a display portion (not shown) by printing, and by peeling the outer label 3, part or all of the display portion of the inner label 4 can be visually recognized. . Moreover, after peeling, the adhesive film 5 cannot be reattached.
[0018]
Here, the outer label 3 and the inner label 4 are mainly composed of a heat-shrinkable film that shrinks in one direction. For example, a polyester film such as a polyethylene terephthalate (PET) film having a thickness of 20 to 60 μm is used. . The outer label 3 and the inner label 4 have the same thickness. However, the thicknesses of the two may be different. Examples of the adhesive film 5 include ethylene vinyl acetate copolymer (EVA), ethylene ethyl acrylate copolymer (EEA), ethylene acrylic acid copolymer (EAA), ethylene methacrylic acid copolymer (EMAA), and ionomer. A PE-modified film having a thickness of 5 to 40 μm such as a resin is used. The anchor coat 6 has a thickness of 1 to 5 μm.
[0019]
The double label 1 is attached to various containers. For example, the double label 1 is for covering the entire length of the container W in which the cap W1 is screwed to the mouth as shown in FIG. That is, the double label 1 has an upper region 10 that functions as a so-called cap seal and is removed from the container W by opening, and a lower region 11 that is left unattached to the container W without being removed at the time of opening. is doing.
[0020]
Specifically, returning to FIG. 1, the double label 1 has a horizontal perforation 20 extending along the circumferential direction so as to divide the double label 1 into an upper region 10 and a lower region 11. Is formed. Also, a pair of left and right first vertical perforations 21 are formed along the vertical direction from the upper end of the double label 1 to the horizontal perforations 20 at a predetermined interval in the circumferential direction. The first vertical perforations 21 and the horizontal perforations 20 are formed so as to penetrate the entire thickness of the laminate film constituting the double label 1. Further, on the inner side of the left and right first vertical perforations 21, second vertical perforations 22 (along the vertical direction over the entire length of the double label 1 at positions near the first vertical perforations 21 ( A pair of left and right cutting lines are formed. The second vertical perforations 22 are formed on the outer label 3 and the adhesive film 5 of the double label 1, but are not formed on the inner label 4. That is, the second vertical perforation 22 penetrates both the outer label 3 and the adhesive film 5. Therefore, at the time of opening, from the upper end of the double label 1 to the horizontal perforation 20, the total thickness of the band-shaped portion of the double label 1 between the first vertical perforations 21, and from the horizontal perforation 20 to the double label 1. Up to the lower end, the belt-like portions of the outer label 3 and the adhesive film 5 between the second vertical perforations 22 become the cut pieces 30 for opening. The horizontal perforations 20 have a two-row configuration, but the first and second vertical perforations 22 each have a single-row configuration. The horizontal perforations 20 are preferable because the two-row configuration is easy to cut, but may be a single-row configuration. Further, in the vicinity of the horizontal perforation 20, a cut (not shown) that connects the lower end of the first vertical perforation 21 and the second vertical perforation 22 is formed.
[0021]
In the double label 1 configured as described above, first, the double label 1 is put on the container W placed as shown in FIG. The container W is heat shrunk and the container W is covered with the double label 1 over the entire length as shown in FIG. Thereby, the cap W1 is prevented from being removed by the upper region 10 of the double label 1. In the case of opening the container W with the double label 1 attached in this way, as shown in FIG. 4 (c), an opening cut located between the first and second vertical perforations 21, 22 The piece 30 is cut off from other portions while cutting the first vertical perforation 21 up to the horizontal perforation 20 and cutting the second vertical perforation 22 below the horizontal perforation 20. . At the time of opening, as described above, since the first vertical perforation 21 penetrates the entire thickness of the double label 1, the inner label 4 is integrated with the outer label 3 until the horizontal perforation 20. Disconnected. And since the 2nd vertical perforation 22 is not formed in the inner label 4 about the lower side from the horizontal perforation 20, the inner label 4 remains as it is without being separated, and the outer label 3 and the adhesive film 5 are Both are separated together. Further, since the second vertical perforation 22 is formed up to the adhesive film 5, the outer label 3 can be easily separated along the second vertical perforation 22.
[0022]
Thereafter, as shown in FIG. 4 (d), the upper region 10 is separated from the lower region 11 along the horizontal perforation 20, and the opening operation is completed. As shown in FIG. In FIG. 2, the lower region 11 of the double label 1 is attached to the body of the container W. At the same time as the opening operation, a part of the outer label 3 in the lower region 11 is separated as a cut piece 30 and the outer label 3 is divided in the circumferential direction at that portion, so that FIG. Thus, the outer label 3 remaining in the container W can be cut off and peeled off in the circumferential direction, starting from the end formed by the separation of the cut piece 30. In addition, since the back surface of the other end portion of the inner label 4 is bonded to the surface of one end portion of the outer label 3 in the overlapping portion 2, In the belt-like region up to the second vertical perforation 22, the outer label 3 remains without being peeled off. By peeling the outer label 3 in this way, the inner label 4 appears and the display portion can be visually observed. Further, since the adhesive film 5 is also peeled off together with the outer label 3, the adhesive film 5 that is easily damaged is not left on the surface of the inner label 4. Thus, it is preferable that the adhesive film 5 is integrally separated together with the outer label 3.
[0023]
Next, the manufacturing method of this double label 1 is demonstrated.
As shown in FIG. 5, the wide original film 100 wound in a roll shape is sequentially fed out, and the original film 100 is continuously divided into right and left by a cutting blade 101. The original film 100 is divided into a first long film 102 and a second long film 103 by this slitting process. The first long film 102 becomes the outer label 3, while the second long film 102 The film 103 constitutes the inner label 4. Accordingly, the display portion of the outer label 3 and the display portion of the inner label 4 are already formed on the original film 100 at regular intervals along the longitudinal direction. In the present embodiment, the first and second long films 102 and 103 have the same width. Then, while continuing to run the first long film 102 downstream, the long adhesive film 104 wound in a roll is superposed on the back surface of the first long film 102, and its downstream point The perforation 105 is formed in both along the longitudinal direction. An anchor coat 6 is applied to the back surface of the first long film 102 when the display portion is printed. The perforation 105 is formed in the vicinity of one side end of the first long film 102 and the long adhesive film 104. For example, a perforation forming blade 106 having a large number of blades protruding at regular intervals on the outer peripheral surface of the roller is used to penetrate both the first long film 102 and the long adhesive film 104. Thus, the perforation 105 is continuously formed. The perforation 105 corresponds to the second vertical perforation 22. Then, after the perforation 105 is formed, the second long film 103 is overlaid on the back surface of the long adhesive film 104. At that time, the front surface side of the second long film 103 is overlapped with the back surface of the long adhesive film 104. This superposition is performed by a pair of upper and lower heat rollers 107 (thermocompression bonding means). Simultaneously with the superposition, the first long film 102, the long adhesive film 104, and the second long film 103 are combined. The three parties are thermocompression bonded, and the formed long laminate film 108 is sequentially wound into a roll. The thermocompression bonding conditions are, for example, a heating temperature of 50 to 200 ° C. and a pressure of 2 to 10 kg / cm ² . In such a thermocompression bonding process, the first long film 102 and the long adhesive film 104 are bonded, while the long adhesive film 104 and the second long film 103 are detachable in a pseudo manner. Glued. In addition, since it performs continuously in a series of processes from the unwinding of the raw film 100 to the winding of the long laminate film 108, the positional deviation in the longitudinal direction of the first long film 102 and the second long film 103 is prevented. Therefore, it is possible to easily prevent the positional deviation between the display portion of the outer label 3 and the display portion of the inner label 4. Furthermore, since it laminates using the elongate adhesive film 104, without apply | coating an adhesive agent, manufacture is easy. Moreover, before laminating the first long film 102 and the second long film 103, the long adhesive film 104 and the first long film 102 are overlapped to form a perforation 105 on both. Therefore, the long laminate film 108 in which the perforation 105 is formed only in the long adhesive film 104 and the first long film 102 can be easily manufactured.
[0024]
After producing the long laminated film 108 for double labels in this way, the long laminated film 108 wound in a roll shape is drawn out, and the left and right side ends thereof are sequentially stacked and bonded together. The tubular long laminate film 108 is wound into a roll while being folded flat. At that time, one of the left and right folds in the folded cylindrical long laminate film 108 is positioned in the middle of the second vertical perforation 22 as shown by a one-dot chain line in FIG. To. Then, a cylindrical long laminate film 108 wound in a roll shape is fed out by, for example, intermittent feeding, and cut at a predetermined length to form a double label 1 as shown in FIG. 6 and a first vertical sewing machine. The eye 21 and the horizontal perforation 20 are formed. In addition, what is necessary is just to employ | adopt a well-known method about formation of such a 1st vertical perforation 21 and the horizontal perforation 20. FIG. It is also possible to continuously perform the manufacturing process of the long laminate film and the cylindrical process.
[0025]
In addition, the double label 1 in another embodiment and its manufacturing method are demonstrated with reference to FIG.7 and FIG.8.
First, the first and second long films 102 and 103 having the same width are formed while the raw film 100 is fed out and divided into right and left sides, and the back surface of the first long film 102 on which the anchor coat 6 is applied. A long perforated adhesive film 104 is overlaid to form a perforation 105 (separation line) along the longitudinal direction (FIG. 7A). The above steps are the same as described above. Thereafter, the second long film 103 is overlaid on the back surface of the long adhesive film 104. At this time, unlike the case described above, the first long film as shown in FIG. The film 102 and the second long film 103 are overlapped so as to be displaced by a predetermined amount in the width direction (left-right direction). Specifically, the second long film 103 protrudes outward by a predetermined amount from the side end portion 102b opposite to the side end portion 102a on the side where the perforation 105 is formed in the first long film 102. To. In such a state, the three members are thermocompression bonded to form a long laminate film 108, and as described above, the left and right ends of the long laminate film 108 are connected to each other as shown in FIG. In this case, the long adhesive film 104 is overlapped on the surface of the protruding portion 103a of the second long film 103 protruding to the side, and the second adhesive film 104 is centered. A part of the protruding portion 103a of the long film 103 is left partially exposed in a slit shape. And it prints on the surface of the 1st elongate film 102 by the inkjet printer etc. in the strip | belt-shaped area | region 110 between the superimposition part 2 and the perforation 105, for example. For example, the expiry date for the contents of the container W to which the double label 1 is to be attached, the serial number, etc. are printed. The long laminate film 108 thus formed is cut into predetermined lengths to form the double labels 1 in sequence.
[0026]
Then, the formed double label 1 is covered with the container W as shown in FIG. 8 (a) and thermally contracted and attached to the container W (FIG. 8 (b)). 4 is exposed in the shape of a slit over the entire length in the axial direction, so that the outer label 3 can be removed from one side end portion 3a as shown in FIG. It can be easily peeled off. As described above, the adhesive film 5 is also peeled off together with the outer label 3. When the outer label 3 is cut off by the perforation 105 as shown in FIG. 8D, only the band-like region 110 between the overlapping portion 2 and the perforation 105 of the outer label 3 remains in the container W. Since the expiry date and the like are printed on the band-like region 110 remaining in the container W, even when the outer label 3 is peeled off and the display portion of the inner label 4 is exposed, the expiry date and the like. Can be easily confirmed. Thus, the design of the double label 1 can be changed as appropriate.
[0027]
And although the structure which mounts | wears with the double label 1 over the full length of the container W was demonstrated in the said embodiment, it cannot be overemphasized even if it is the structure mounted | worn only to the trunk | drum of the container W.
[0028]
Also, various changes can be made to the perforation configuration, formation location, and the like, and cutting lines other than the perforations may be used.
Further, it may be a multiple label more than a triple label.
[0029]
【The invention's effect】
As described above, since both the inner and outer labels are laminated using an adhesive film instead of the conventional adhesive, it is easier to manufacture than the adhesive and the variation in force required for peeling the outer label There are few. In addition, since the adhesive film is simultaneously cut when the predetermined portion of the outer label is cut, the outer label can be easily cut.
