Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the embodiments shown below, the same or common parts are denoted by the same reference numerals in the drawings, and the description thereof will not be repeated.

(Embodiment 1)
FIG. 1 is a perspective view of a labeled adherend according to Embodiment 1. FIG. 2 is a side view of the labeled adherend according to Embodiment 1. FIG. A labeled adherend 100 according to Embodiment 1 will be described with reference to FIGS. 1 and 2. FIG.

As shown in FIGS. 1 and 2, a labeled adherend 100 according to the embodiment is an adherend 10 to which a label 20 is attached. The adherend 10 is, for example, a packaging box containing various articles such as medicines, sweets, or cosmetics. The adherend 10 has an adherend surface 11 to which the label 20 is adhered and a connection surface 12 connected to the adherend surface 11 . A ridgeline 13 is formed at the boundary between the adherend surface 11 and the connecting surface 12 . The surface 11 to be adhered has a ridge line 13 on one end side to which the connection surface 12 is connected.

The label 20 is adhered to the adherend surface 11 located near the ridgeline 13 . When the label 20 is adhered to the surface 11 to be adhered, a part of the label 20 protrudes from the surface 11 to be adhered to the outside of the ridge line 13 . The label 20 has a contact portion 31 that contacts the adherend 10 and a protruding portion 32 that protrudes from the contact portion 31 so as to be separated from the adherend 10 in the adhered state.

A design 15 is formed on the adherend surface 11 . The label 20 is adhered to the adherend surface 11 such that the design 15 overlaps the first base material 21 described later. In the present embodiment, when the label 20 is adhered to the adherend surface 11, the design 15 is exposed from the first base material 21 (more specifically, the portion exposed from the second base material 22). The first base material 21) of is visually recognized.

The label 20 includes a first substrate 21 , a second substrate 22 , an adhesive portion 231 , a weak adhesive portion 232 and an adhesive layer 24 .

The first base material 21 has a front surface 21a and a back surface 21b, and a first edge portion 21c and a third edge portion 21d. The first edge portion 21c constitutes an edge portion of the contact portion 31 on the side opposite to the projecting direction in which the projecting portion 32 projects from the contact portion 31 in the attached state. The first edge portion 21c overlaps the adherend surface 11 in the adhered state. The third edge portion 21d is the edge portion of the first base material 21 positioned in the projecting direction in the adhered state. The third edge portion 21d is located on the side opposite to the side on which the first edge portion 21c is located in the direction parallel to the projecting direction.

The back surface 21b has a projecting region R3 and an overlapping region (contact region) R4. The protruding region R3 protrudes outside the ridge line 13 in the adhered state. The overlapping region R<b>4 is positioned inside the ridgeline 13 (on the side of the surface to be adhered 11 ) in the adhered state and overlaps the surface to be adhered 11 . The overlapping region R4 is in contact with the adherend surface 11 in the adhered state.

An adhesive layer 24 for adhering the first base material 21 to the adhering surface 11 is provided on the back surface 21b. The adhesive layer 24 is made of, for example, a pressure-sensitive adhesive, a heat-sensitive adhesive, or the like.

In the projecting region R3, the adhesive layer 24 is provided entirely, but the adhesive layer 24 provided in the projecting region R3 is provided with the non-adhesive treatment layer 25. As shown in FIG. Accordingly, even when the label 20 is bent toward the connecting surface 12, the projecting region R3 can be prevented from adhering to the connecting surface 12. FIG.

In the overlap region R4, the adhesive layer 24 passes through the end portion located closest to the first edge portion 21c of the second edge portion 22c of the second base material 22, which will be described later, and connects the contact portion 31 and the contact portion 31. At least a bonding region is provided in a region R5 positioned between a virtual line VL1 (see FIG. 3) parallel to the boundary with the projecting portion 32 and the boundary. In addition, in the present embodiment, the boundary portion extends along the ridge line 13 .

In the present embodiment, the adhesive layer 24 is provided entirely in the overlapping region R4, and the adhesive layer 24 provided in the overlapping region R4 is entirely adhered to the adherend surface 11. As shown in FIG. Thereby, the 1st base material 21 can be stuck to the to-be-adhered surface 11 more stably. Note that the adhesive layer 24 may be partially provided in the overlap region R4 as long as it has an adhesive region at least in part of the region R5.

Since the first base material 21 occupies a large area of the label, it is preferably a transparent thin base material made of a plant-derived or natural material. can be reduced. More preferably, the first base material 21 is mainly made of paper material, and may have a structure in which paper and a plant-derived material are laminated.

As described above, the first base material 21 includes a paper material. Note that the first base material 21 may be composed of a single paper material. The paper material preferably has a haze value of 99% or less, more preferably 75% or less. The Haze value is a value measured using a UV-visible spectrophotometer UV-2600 (manufactured by Shimadzu Corporation) and a haze meter NDH7000 (manufactured by Nippon Denshoku Industries Co., Ltd.).

As a paper material having such a haze value, for example, tracing paper, glassine paper, or the like can be used. The tracing paper has a haze value of greater than 75% and no greater than 99% and is translucent. When such a translucent paper material is used, the design 15 formed on the surface 11 to be adhered can be slightly seen through in the adhered state. Thereby, a transparent feeling can be given.

On the other hand, glassine paper has a haze value of 75% or less and has transparency. Glassine paper is thinner and less stiff than tracing paper. In the case of selecting a paper material having such low stiffness, the present invention can be suitably applied as described later. Further, when glassine paper is used, the design 15 formed on the surface 11 to be adhered becomes more transparent in the adhered state. In this case, it is possible to give a clearer sense of transparency.

Note that the front surface 21 a of the first base material 21 may be coated with a paint that improves the transparency of the first base material 21 . Varnish, for example, can be used as the paint. As the varnish, for example, various known varnishes such as those using polyimide-based resin, polyester-based resin, or epoxy-based resin can be used.

By applying paint to the front surface 21a, the smoothness of the front surface 21a is improved, thereby suppressing light scattering and improving transparency. For example, the Haze value of the paint-applied portion can be 55% or less.

The paint may be applied to the entire front surface 21a, or may be applied to a portion thereof. The paint can also be applied to a portion of the first substrate 21 where the transparency is desired to be improved. For example, the paint may be applied to the portion of the front surface 21a corresponding to the overlapping region R4, or may be applied to the portion of the front surface 21a exposed from the second base material 22 .

The paint may be applied before the second base material 22 is adhered to the first base material 21, or when the paint is applied to the portion of the front surface 21a exposed from the second base material 22, The paint can be applied even after the second substrate 22 is adhered to the first substrate 21 or after the label 20 is not adhered to the adherend 10 .

The compressive strength of the glassine paper is smaller than that of the PET base material (K2411). Compressive strength is measured based on ISO12192, for example, using AUTOGRAPH AG-X 500N (manufactured by Shimadzu Corporation). For example, the compressive strength of glassine paper is about 9 to 12N, and the compressive strength of PET base material (K2411) is about 20 to 23N. As described above, glassine paper alone has almost no stiffness and is easily broken or curled.

The second base material 22 has a front surface 22a and a back surface 22b, and a second edge portion 22c. The second base material 22 is arranged on the front surface 21a side of the first base material 21 . The second edge portion 22c is located on the side opposite to the projecting direction in the adhered state. The second edge portion 22c overlaps the adherend surface 11 in the adhered state. A design layer may be formed on the front surface 22a.

The back surface 22b of the second base material 22 functions as a facing surface facing the first base material 21 (more specifically, the front surface 21a).

The back surface 22b has a first region R1 and a second region R2. When the label 20 is viewed from the front in the attached state (when viewed along the lamination direction in which the first base material 21 and the second base material 22 are laminated), the first region R1 is the protrusion part. It overlaps the first substrate 21 at 32 . The first region R1 protrudes outward from the ridgeline 13 . The second region R2 overlaps the first substrate 21 at the contact portion 31 when the label 20 is viewed from the front in the attached state. The second region R2 overlaps the first base material 21 inside the ridgeline 13 .

A bonding portion 231 for bonding the second base material 22 and the first base material 21 is provided between the first region R1 and the first base material 21 . The adhesive portion 231 is made of, for example, a pressure-sensitive adhesive, a heat-sensitive adhesive, or the like.

Between the second region R2 and the first base material 21, a weak adhesion portion 232 having a weaker adhesive force than the adhesion portion 231 is provided. The weakly bonded portion 232 is provided so that the second base material 22 can be peeled off from the first base material 21 in the second region R2.

The weak adhesion portion 232 may be formed by partially applying a pressure-sensitive adhesive or a heat-sensitive adhesive to the second region R2, or may be formed by applying a pressure-sensitive adhesive or a heat-sensitive adhesive to the second region R2. It may be formed by performing a weak adhesion treatment on the whole or partially.

As a weak adhesion treatment, for example, a surface treatment liquid such as a liquid containing a release agent such as silicone resin (such as ultraviolet curing ink) or a coating liquid containing fine particles (such as matte ink) is applied to a predetermined area. do.

A non-bonded portion that does not bond the second base material 22 and the first base material 21 may be provided instead of the weakly bonded portion 232 . The non-adhesive portion may be configured by not forming an adhesive portion between the second region R2 and the first base material 21, or may be provided between the second region R2 and the first base material 21. You may perform the process which loses adhesiveness to the adhesion part which was attached.

The second base material 22 is stiffer than the first base material 21 . That is, the compressive strength of the second base material 22 is higher than that of the first base material 21 .

As the second base material 22, plain paper, synthetic paper, metallized paper, gloss paper, synthetic resin film, etc. can be appropriately employed as long as they are stiffer than the first base material 21, as described above. As the synthetic resin film, for example, polyolefin-based films such as polyethylene, polypropylene, cyclic olefins, and copolymers containing polyethylene, polyester-based films such as polyethylene terephthalate, polyamide-based films, and polystyrene-based films can be used. In addition, if the second base material 22 is made of a plant-derived or natural material or a paper material, the environmental load can be further reduced.

FIG. 3 is a front view of the label according to Embodiment 1. FIG. With reference to FIGS. 2 and 3, the adhered state of the label 20 will be described.

As shown in FIGS. 2 and 3, the adhesive layer 24 has an adhesive region at least in the region R5 as described above, thereby allowing the first base material 21 to adhere to the adherend surface 11. can be done.

The second edge portion 22c is provided in a straight line and extends in a direction parallel to the ridge line 13 when the label 20 is viewed from the front in the adhered state. The second edge portion 22c is positioned between the boundary portion between the contact portion 31 and the projecting portion 32 and the first edge portion 21c when the label 20 is viewed from the front in the adhered state.

Here, since the first base material 21 has a small stiffness (almost no stiffness) as described above, the first base material 21 alone may curl or fall down. 2, the second base material 22 having greater stiffness (strength in stiffness) than the first base material 21 is superimposed on and adhered to the first base material 21 . Thereby, the first base material 21 can be reinforced by the second base material 22 .

At this time, since the second edge portion 22c is positioned between the boundary portion and the first edge portion 21c when viewed from the front, the contact portion 31 (inner side of the ridgeline 13) in the adhered state The portion of the first base material 21 located at the position can also be reinforced. This makes it difficult for the first base material 21 to break at the boundary.

As a result, in the label 20 according to Embodiment 1, it is possible to maintain a stable posture in the adhered state, and to ensure sufficient shape retention. In addition, since at least the first base material 21 contains a paper material, the load on the environment can be reduced.

Furthermore, in Embodiment 1, as described below, even if it is bent, it can be easily restored to the upright state.

In general, when a labeled adherend is packed in a packing material and transported in a distribution process, the portion of the label protruding from the adherend is pressed by the inner surface of the packing material, etc. It may be bent. In particular, when using a paper material with low stiffness (almost no stiffness) as the base material, the paper material has a dead-hold property, so when the paper material is bent, it is difficult to return to its original position. Become.

On the other hand, in the present embodiment, as described below with reference to FIGS. can be returned to a standing position.

4 is a side view showing a state in which the labeled adherend according to Embodiment 1 is packed and the label is bent. FIG. FIG. 5 is a diagram showing how the bent label is restored in the labeled adherend according to Embodiment 1. FIG. FIG. 6 is a diagram showing a state in which the bent label is restored in the labeled adherend according to Embodiment 1. FIG.

When the portion of the label 20 protruding from the adherend 10 is bent toward the connection surface 12 as shown in FIG. Since it is weak, the second base material 22 separates from the first base material 21 in the second region R2. As a result, the posture of the second base material 22 is changed without being bent. When the posture of the second base material 22 is changed, the second edge portion 22c side of the second base material 22 protrudes outward from the connection surface 12 when the connection surface 12 is viewed from the front.

As shown in FIG. 5, when the folded label 20 is returned to the upright state, the portion of the second base material 22 projecting outward from the connecting surface 12 is adhered as indicated by the arrow in the drawing. Push toward the landing surface 11 .

Here, the second base material 22 is stiffer and stiffer than the first base material 21 . Therefore, when the portion of the second base material 22 protruding outward from the connection surface 12 is pushed toward the adherend surface 11, as shown in FIG. Then, the label 20 stands up as a whole. Furthermore, in the upright state of the label 20 , the portion of the second base material 22 that protrudes outward from the connecting surface 12 is again adhered to the weak adhesion portion 232 . Thereby, the label 20 can maintain a more stable posture.

As described above, in the label 20 according to the first embodiment, even if the label 20 is bent, it can be easily restored to the upright state.

It should be noted that the second edge portion 22c of the second base material 22 in Embodiment 1 can be modified as in Modified Examples 1 to 5 below. FIGS. 7 to 11 are front views of attached labels according to modified examples 1 to 5. FIG.

The curved portion 22d curves toward the edge portion 22h of the second substrate 22 located on the opposite side of the second edge portion 22c as it extends outward in the direction parallel to the boundary portion. Assuming that the direction parallel to the boundary portion is the width direction of the second base material 22, the starting point S1 of the curved portion 22d is located in the second width direction in the width direction rather than the central portion of the second edge portion 22c in the width direction. They are positioned on both end sides of the edge portion 22c. More specifically, the starting point S1 of the curved portion 22d is located near both ends of the second edge portion 22c in the width direction.

The inclined portion 22e is inclined so as to approach the edge portion 22h of the second base material 22 located on the opposite side of the second edge portion 22c as it goes outward in the direction parallel to the boundary portion.

As shown in FIG. 10, in the label 20D according to Modified Example 4, only the two end sides of the second edge portion 22c in the width direction are positioned closer to the first edge portion 21c than the boundary portion. . The portions of the second edge portion 22c other than the two end portions are substantially linear and positioned substantially at the same position as the boundary portion. The second edge portion 22c has curved portions 22f on both sides in the width direction. The curved portion 22f curves toward the first edge portion 21c as it goes outward in the direction parallel to the boundary portion.

Each of the plurality of protruding portions 22g is located closer to the first edge portion 21c than the boundary portion when the label 20 is viewed from the front in the adhered state. Each of the plurality of projecting portions 22g has, for example, a substantially semicircular or substantially semi-oval shape.

The shape of the second edge portion 22c may be modified as in Modifications 1 to 5 described above. Note that Modifications 1 to 5 are examples, and the second base material 22 is located closer to the first edge portion 21c of the first base material 21 than the ridge line 13 in the adhered state. The shape of the second edge portion 22c can be changed as appropriate, as long as it has a region overlapping with . Also in this case, substantially the same effect as in the first embodiment can be obtained.
