The inner substrate 3 is made of, for example, a plastic film having a rectangular shape, and includes a first substrate 3a and a second substrate 3b. In addition, the 1st base material 3a and the 2nd base material 3b form the slit 2 in the plastic film, and are dividing the inner base material 3 into two. On the inner surfaces of the first base material 3a and the second base material 3b, a re-adhesion layer 7 formed by applying a weak adhesive is provided. Such a re-adhesion layer 7 is an adhesive layer that can be peeled off even after being bonded, and has adhesiveness even after peeling and is provided so that it can be bonded again. And the 1st base material 3a and the 2nd base material 3b are adhere | attached on the release paper 4 through the rebonding layer 7 so that peeling is possible. In order to form a knob 6 having no adhesive force on the back surface of the re-adhesion layer 7 at the edge on the one end side of the first base material 3a, a masking layer 7a for masking the adhesive with ink or the like is provided. It has been.
[0016]
The outer base material 5 is made of a strip-shaped plastic film (longer than the plastic film of the inner base material 3), and an arbitrary label such as a barcode or a product name is provided on the surface side of the label base material 5. Is provided by printing or the like. The width of the outer base material 5 (short side length) is set to be equal to the width of the inner base material 3. Moreover, the outer base material 5 is folded in multiple numbers. Specifically, the outer base material 5 is folded in three, and includes an outer portion 5a, an intermediate portion 5b, and an inner portion 5c from the outside.
[0017]
One end portion 5a1 of the outer portion 5a is bonded to the first base material 3a via a hot melt adhesive 8a as an adhesive. In addition, the said glue suppression layer 7a is located in the back surface of the one end part 5a1 of the outer side part 5a. The other end of the outer portion 5a and one end of the intermediate portion 5b are connected by a bent portion 5e, and the other end of the intermediate portion 5b and one end of the inner portion 5c are connected by a bent portion 5f.
[0018]
The other end 5c1 of the inner part 5c is bonded to the second base material 3b via a hot melt adhesive 8b. The bent portion 5e connecting the outer portion 5a and the intermediate portion 5b protrudes from the other end portion 5c1 of the inner portion 5c, and the bent portion 5e is a non-adhesive layer 10 such as silicone applied to the bent portion 5e. It is difficult to adhere to the hot melt adhesive 8b via the adhesive, and it does not inadvertently peel off.
[0019]
Next, the process for manufacturing the label will be described with reference to FIGS.
First, the long plastic film 12 bonded to the long release paper 4 is fed out in the direction of the arrow. The long plastic film 12 forms the inner substrate 3, and slits 2 are continuously formed in the plastic film 12 in the longitudinal direction (feed direction). Further, an adhesive layer 7 a for forming the knob 6 is applied to the back surface of the re-adhesion layer 7 that adheres the plastic film 12 to the release paper 4.
[0020]
Next, the melted hot melt adhesives 8a and 8b are linearly applied to the upper surface of the plastic film 12 from an application means 13 such as a nozzle such as a hot melt applicator (a portion in FIG. 6).
[0021]
Further, a long plastic film (which becomes the outer base material 5) 15 folded into a predetermined shape is supplied to the upper surface of the plastic film 12, and the plastic film 15 and the plastic film 12 are paired with a pair of rolls 16. (B portion in FIG. 6). The non-adhesive layer 10 is applied to the plastic film 15 in advance.

Subsequently, the plastic film 15 and the plastic film 12 are cut into a predetermined shape by the cutting blade 18, and unnecessary portions 19 of both the plastic films 12 and 15 are removed (so-called residue raising) (the portion c in FIG. 6). Are attached to the long release paper 4 in a large number and intermittently attached to the label-attached sheet supply belt-like body 20.
[0023]
According to such a method for manufacturing a label, a series of processes from the step of supplying the plastic film 15 and the plastic film 12 to the step of providing a large number of labels 1 on the long release paper 4 by raising the residue is performed. Since it can be performed in the process, the label-attached sheet supply belt can be manufactured easily and quickly.
[0024]
Next, the case where the label 1 is used for a bag-like package in which an object to be stored such as food is stored will be described with reference to FIGS.
The label-attached sheet supply belt-like body 20 is attached to a tack labeler (not shown), and the label 1 is peeled off from the release paper 4 so that the label 1 is attached to the package body 22 that has been transferred by a conveyor (not shown). Glue. The package body 22 is, for example, a bag-like package body in which an object to be stored such as food is stored inside, and the inside is sealed by heat sealing the upper and lower ends.
As described above, the label 1 can be automatically adhered and attached to the package body 22 efficiently by the tack labeler. However, the label 1 is peeled off from the release paper 4 and packaged even by manual work. Since it can be performed by a simple operation of simply adhering to the body main body 22, it is efficient.
[0025]
The label 1 is adhered to the outer surface of the package body 22 via the re-adhesion layer 7 so that a display such as a barcode printed on the surface of the outer portion 5a of the outer base 5 can be visually recognized. In the case where such a package body 22 is opened and an internal storage object is used, the upper portion of the package body 22 is cut to form an opening.
[0026]
When the package body 22 once opened in this way is to be sealed again, for example, in order to store the remainder of the package after opening, the upper portion 22a of the opened package body 22 is shown in FIG. Bend as shown. Further, the grip portion 6 of the label 1 is gripped, and the one end portion 5 a 1 of the outer portion 5 a is peeled from the package body 22. At this time, the outer portion 5a and the first base material 3a are bonded by the hot melt adhesive 8a, and the first base material 3a is formed by the re-adhesion layer 7 having a lower adhesive strength than the hot melt adhesive 8a. The first base material 3 a is peeled off from the package body 22 together with the outer portion 5 a.
[0027]
One end side of the outer base material 5 peeled off from the package body 22 is extended toward the upper side of the package body 22, and the first substrate 3a is bonded to the bent upper portion 22a (see FIGS. 3 and 4). . Since the outer base 5 is expanded and the outer portion 5a, the intermediate portion 5b, and the inner portion 5c are exposed, it is possible to visually recognize the display of instructions printed on the intermediate portion 5b and the inner portion 5c. become.
[0028]
Since the 1st base material 3a of the label 1 is adhere | attached on the packaging body main body 22 by the re-adhesion layer 7 which can be peeled as mentioned above, the 1st base material 3a can be peeled easily and a packaging body again. An object to be stored can be taken out from the main body 22. In addition, the present embodiment does not form an elongated portion by forming a notch while leaving a connection portion on the label base material as in a conventional label, and the outer base material 5 folded multiple times is formed. Since it is the structure extended | stretched, when the outer base material 5 is extended | stretched, it does not fracture | rupture.
[0029]
The present invention is not limited to the above embodiment. For example, in another embodiment shown in FIG. 7 (a), the end of the bent portion 5e connecting the outer portion 5a and the intermediate portion 5b and the end of the tip portion 5c1 of the inner portion 5c are bent. Is. In such a case, the bent portion 5e and the tip portion 5c1 of the inner portion 5c are temporarily bonded by the weak adhesive layer 25.
[0030]
The other embodiment shown in FIG. 7 (b) has a configuration in which the outer base material 5 is folded in five, and since the outer base material 5 can be set longer, there is an advantage that the display area of the outer base material 5 can be further increased. is there. The number of times of folding the outer base material 5 is not limited to this, and can be increased.
[0031]
Such a use mode as a label capable of expanding the display area is not limited to the case of sealing the opening of the bag-like package as described above, but the label 1 is attached to the rigid container body 26 as shown in FIG. It may be adhered. Even in such a case, it is possible to visually recognize various displays printed on the outer base material 5 by extending the label 1 as indicated by a virtual line. Further, when not required, the label 1 can be folded, which is convenient without being disturbed.
[0032]
Another embodiment shown in FIG. 9 is provided with a plurality of folding parts of the outer base material 5. Specifically, the back surfaces of the pair of folding parts are arranged to face each other, and both sides of the outer base material 5 can be extended. This embodiment also has an advantage that the display area of the outer base material 5 can be further increased because the outer base material 5 can be set longer. In addition, each bending part 5e and the other end part 5c1 of the inner side part 5c are temporarily bonded by the weak adhesion layer 25. FIG.
[0033]
Moreover, in this embodiment, the knob | pick part 6 to which the hot-melt-adhesive 8a is not adhere | attached protrudes and provided in the front-end | tip of the one end part 5a1 of the outer side part 5a. Thus, when the knob | pick part 6 is protruded and provided, the said glue suppression layer 7a is unnecessary. When the knob 6 protrudes in this way, it cannot be formed by simultaneously cutting (cutting) the plastic film 15 and the plastic film 12 and then simultaneously cutting them with the cutting blade 18. Therefore, first, the long plastic film 12 bonded to the long release paper 4 is cut to a predetermined width, and then the plastic film 15 serving as an outer base material is attached to the plastic film 12 by the knob 6. Overlaying at a position where it can be formed, both films are cut to a predetermined length in the feed direction.
[0034]
In addition, this invention is not limited to the said embodiment, The 1st base material 3a and the 2nd base material 3b make the inner base material 3 form the perforation, and make it fracture | rupture Also good.
[0035]
【The invention's effect】
As described above, the label of the present invention, it is possible to readily adhere to the package if example embodiment, it is possible to stretch the peeled off the substrate from the package. Therefore, it can be used as a label for easily resealing an opened package such as a bag.
[0036]
Moreover, for re-sealing, the outer base material is simply stretched as it was folded, so it was stretched compared to the conventional case where the cut portion was formed by leaving the connection portion on the label base material. There is an advantage that the display area can be increased without breaking, and a large amount of information can be included. In addition, since the outer base material is folded a plurality of times so as to be stretchable, the structure is also simple.
