Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a labeled container for mounting a label on a container body and a mounting method thereof.
[0002]
[Prior art]
Conventionally, for example, as shown in FIG. 6A, a container body 50 such as a plastic bottle is generally provided with a label 51 printed with characters, patterns, and the like. The label 51 includes a transparent label base material 53 made of a plastic film, a printing layer 54 of characters and patterns laminated on the inner surface of the label base material 53, and a white ink laminated on the inner surface of the printing layer 54. The label main body 57 is composed of the concealing layer 55 formed by the above. The surface of the white ink printing layer of the concealing layer 55 is formed in a fine uneven shape. Adhesives 58a and 58b are respectively applied to the innermost concealing layers 55a and 55b at both ends 57a and 57b of the label main body 57.
[0003]
When the label 51 is attached to the container body 50, for example, one end portion 57a of the label body 57 is bonded to the surface of the container body 50 via an adhesive 58a, and the container body 50 is rotated so that the label body The label 51 was wound around the container body 50 by bonding the adhesive 58b of the other end 57b of the 57 to the one end 57a.
[0004]
[Problems to be solved by the invention]
However, the adhesive 58a of the one end portion 57a of the label body is adhered to the surface of the container body 50, the adhesive 58b of the other end portion 57b is adhered to the surface of the one end portion 51a, and both the adhesives 58a. , 58b overlap each other.
[0005]
For this reason, when the adhesive is applied to the concealed concealing layer 55, the concealing effect due to irregular reflection almost disappears. This is, for example, the same phenomenon as when a transparent pressure-sensitive adhesive tape is attached to the concavo-convex surface of frosted glass, the concealing layer 55 is easily seen, and the portion of the label provided with the adhesive appears black in a band shape. Alternatively, in addition to the color of the concealment layer 55, particularly when the container body 50 itself is a dark color such as black, blue, or red, or when the container body is transparent and the content color is dark, The color may show through and appear black.
[0006]
Therefore, it is conceivable to increase the number of times of printing with white ink to increase the thickness of the concealing layer. However, in such a case, there is a disadvantage that the printing process becomes complicated or the amount of white ink increases, resulting in an increase in manufacturing cost.
[0007]
The object of the present invention is to reduce the manufacturing cost without complicating the printing process of the concealing layer, and to prevent the bonded portion of the label from changing color compared to other portions. The purpose is to improve the appearance.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the present invention has been made as a container with a label and a method for attaching the label. The feature as a container with a label is that a printed layer 8 and a concealing layer 10 are formed on a transparent label substrate 7. An adhesive 13a is applied to at least one end of the label body 11 formed by laminating, and one end of the label body 11 is bonded to the surface of the container body 11 via the adhesive 13a, and the adhesive 13a is applied. The concealing layer 10 provided on the other end side of the label main body 11 is provided so as to overlap the one end portion. Moreover, it is preferable that this adhesive agent is apply | coated to the base material (transparent part).
[0010]
The label mounting method is characterized in that an adhesive 13a is applied to at least one end of a label body 11 in which a printing layer 8 and a concealing layer 10 are laminated on a transparent label base material 7, and one end side of the label body 11 Is adhered to the surface of the container main body 11 via an adhesive 13a, and the label main body is overlapped with the concealing layer 10 provided on the other end of the label main body 11 at one end where the adhesive 13a is applied. 11 is attached to the container body 11.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 3, reference numeral 1 denotes a container in which a label (heat-sensitive label) 5 is mounted on a container body 3 such as a blow-formed colorless and transparent or colored opaque polyethylene terephthalate, polyethylene, or glass bottle. Examples of the contents include beverages such as cola, and dark colors such as sauce and soup.
[0013]
The label 5 is formed by cutting an elongated label long body 1a at a predetermined position as shown in FIG. 1, and includes a transparent label substrate 7 and a back surface (inner surface) of the label substrate 7. And a concealing layer 10 laminated on the inner surface of the printing layer 8. A label main body 11 is constituted by the label base material 7, the printing layer 8 and the concealing layer 10. The transparency of the label base material 7 refers to the degree that the printed layer 8 can be visually observed through the label base material 7.
[0014]
Moreover, as the concealment layer 10, the surface is formed in an uneven shape with white ink containing a white pigment made of titanium oxide. The masking layer 10 exhibits an excellent masking effect due to the diffused light reflection effect of white ink.
Examples of the label substrate 7 include a synthetic resin film having a thickness of about 20 μm to 100 μm made of a biaxially stretched film of polyethylene terephthalate or polypropylene, a polyvinyl chloride film, a polystyrene film, or the like.
[0015]
The length (interval L) of the label main body 11 is provided slightly longer than the peripheral length of the container main body 3 to which the label 1 is mounted. Adhesive portions 7a and 7b where the concealing layer 10 is not provided are formed. Both of the adhesive portions 7a and 7b are respectively coated with hot melt adhesives (heat-sensitive adhesives) 13a and 13b that are activated by heating, and these portions are completely not overlapped with each other. It has been shifted to. That is, the heat-sensitive adhesive 13a of one adhesive part (one end side) 7a of the label main body 11 is adhered to the surface of the container main body 3, and further the heat-sensitive adhesive of the other adhesive part (other side) 7b of the label main body 11. 13 b passes through the one adhesive portion 7 a and is adhered to the surface of the portion 7 c of the label base material 7 without the heat-sensitive adhesive.
[0016]
Next, the case where the label 1 is mounted on, for example, a blown molded container body 3 having a circular shape in plan view will be described. A long label 1a for forming the label 1 is shown in FIG. And the label 1 is formed by cut | disconnecting the center (position shown by the virtual line A) of the heat-sensitive adhesive 13 currently apply | coated to the label elongate body 1a at predetermined intervals.
[0017]
Furthermore, the heat-sensitive adhesives 13a and 13b applied to both ends of the label 1 are heated and activated.
[0018]
Next, one end of the label 1 is bonded to the container body 3 via one heat-sensitive adhesive 13a, and the container body 3 is rotated in the direction of arrow B in a state where the label 1 is tensioned (FIG. 2 (A) The label 1 is sequentially wound along the container body 3 by the rotation of the container body 3 (see FIG. 2B).
[0019]
Furthermore, the label 1 is wound, and the other end-side heat-sensitive adhesive 13b passes through the one heat-sensitive adhesive 13a bonding the label main body 11 to the container main body 3, and the portion of the base material 7 without the heat-sensitive adhesive The adhesive portions of the heat-sensitive adhesives 13a and 13b are pressed with a cooling pressure bar (not shown) until the heat-sensitive adhesives 13a and 13b are cooled and solidified (FIG. 2C). reference).
[0020]
Since the container 1 formed as described above is shifted in the position of one adhesive 13a and the other heat-sensitive adhesive 13b as shown in FIG. The portion where 13a and 13b are located) does not change color because it looks dark.
[0021]
Specifically, since the concealment layer 10 is maintained in a concavo-convex state without being affected by the heat-sensitive adhesive, the concealing effect of the concealment layer 10 is not lowered and the color of the container body 3 is reduced. The color of the contents is not transparent.
Moreover, even if the color of the container body 3 and the color of the contents are transparent through the one end of the label body 11 and the heat-sensitive adhesive 13a that bonds the one end of the label body 11 to the container body 3. The concealing layer 10 at the other end of the label main body 11 covers the heat-sensitive adhesive 13a and one end of the label main body 11, so that the color of the concealing layer 10 where the one heat-sensitive adhesive 13a is located, the color of the container main body 3, etc. Label 1 does not appear partially dark. The heat-sensitive adhesive 13b at the other end of the label main body 11 is adhered to the surface of the label base material 7, but the uneven state is maintained on the inner surface of the label base material 7 where the heat-sensitive adhesive 13b is located. Further, since the concealing layer 10 is present, the concealing effect of the bonded portion of the label is not lowered.
[0022]
FIG. 4 shows another embodiment of the present invention. That is, among the heat-sensitive adhesive 13 applied to the long label 1a, the printed layer 8 and the concealing layer 10 are laminated on the one end side of the label base material 7 up to the position of the cutting line A. The other heat-sensitive adhesive 13b is directly applied to the label base material 7 on the other end side of the label base material 7 as in the above embodiment.
[0023]
Therefore, the label 1 is formed by cutting the long label 1a along the cutting line A, and the label 1 is attached to the container body 3 in the same manner as described above. In such a case, since one heat-sensitive adhesive 13a is in close contact with the masking layer 10 on one end side of the label 1, the surface of the masking layer 10 has no irregularities and the masking effect is reduced. Since the masking layer 10 that is not affected by the other heat-sensitive adhesive 13b is covered, the masking layer 10 on one end side of the label body 7 does not appear dark.
[0024]
Further, as shown in FIG. 5, the present invention can also be applied to a case where a shrink label 1 formed in a cylindrical shape is attached to a container body 3. Here, the shrink label 1 comprises a label base material 7 from a film having heat shrinkability in the circumferential direction of the label, and the printing layer 8 and the concealing layer 10 are laminated on the label base material 7.
[0025]
Conventionally, as shown in FIG. 6 (b), a heat-sensitive adhesive 60 is applied to the inner surface of the shrink label 51 so that the shrink label 51 does not inadvertently come off from the container body 50. The shrink label 51 is fixed to the container body 50 with the agent 60. Therefore, also in such a case, the adhesive 60 reduces the hiding effect of the hiding layer.
[0026]
When the shrink label 1 is heat-shrinked and attached to the container body 3, as shown in FIG. 1 (b) or FIG. 4 (b), a heat-sensitive adhesive 13a for bonding the label 1 to the container body 3, Since the position of the label body 7 is shifted from the position of the adhesive 13b that bonds the other end of the label body 7 to the portion where the adhesive is not provided, The label main body 11 can be attached to the container main body 11 so that the masking layer 10 provided on the other end side overlaps. Therefore, it is possible to prevent the concealing layer 10 and the contents in the container body 3 from being seen through and appearing dark. The other end side is adhered to a predetermined position of the label body 7 via the adhesive 13b. However, the adhesive 13b is not necessarily provided, and a method not using an adhesive includes a welding method and a heat fusion method. Is used.
[0027]
【The invention's effect】
As described above, according to the present invention, since both the adhesives of the label base material are provided at positions shifted so as not to overlap each other, the bonded portion of the label changes color depending on the color of the concealing layer, the container body, and the like. In particular, it is optimal for filling dark colored containers such as black, blue, and red, and a transparent container main body with dark colored contents, and can improve the appearance.
[0028]
In addition, since it is not necessary to increase the thickness of the masking layer by increasing the masking layer printing process, there is an advantage that the manufacturing cost can be reduced.
