Description

[Technical field]

[0001] The present disclosure relates to labels and labeled substrates. [Background technology]

[0002] Conventionally, POP labels (hereinafter sometimes simply referred to as labels) that protrude from the product have been affixed to products in which various items are packaged in packaging boxes (adherends) primarily for advertising purposes.

[0003] As an example of such a POP label, Japanese Patent Application Laid-Open No. 2001-134190 discloses a label having a laminate structure in which a second substrate and a first substrate are laminated and bonded together. The first substrate includes an attachment portion to be attached to an adherend and a display portion connected to the attachment portion, and the second substrate is attached to the display portion. The attachment portion is exposed from the second substrate, and when the label is attached to the adherend, the second substrate generally protrudes from the ridge (edge) of the surface to which it is attached. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2001-134190 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the label disclosed in Patent Document 1, the first substrate is made of a synthetic resin film such as a polypropylene film, a polyester film, etc. Such synthetic resin films have a large environmental impact, and there is a demand for reducing the environmental impact.

[0006] On the other hand, if a paper material is simply used for the first base material in consideration of the environmental impact, the paper material is weaker than a synthetic resin film and tends to curl, so that the first base material tends to collapse.

[0007] The present disclosure has been made in consideration of the above-mentioned problems, and an object of the present disclosure is to provide a label that is environmentally friendly and can ensure sufficient shape retention, and a labeled object to which the label is affixed. [Means for solving the problem]

[0008] The label according to the present disclosure has, in an attached state in which the label is attached to an adherend, an abutting portion that abuts against the adherend and a protruding portion that protrudes from the abutting portion so as to be separated from the adherend. The label includes a first substrate having a front surface and a back surface and including the abutting portion and the protruding portion, a second substrate superposed on the front surface side of the first substrate, and an adhesive layer provided on the back surface of the first substrate for attaching the first substrate to the adherend. The first substrate includes a paper material. The second substrate is stiffer than the first substrate and is disposed on the front surface side of the first substrate. The first substrate includes a first edge portion that constitutes an edge portion of the abutting portion on the side opposite to the protruding direction in which the protruding portion protrudes from the abutting portion in the attached state. The second substrate includes a second edge portion on the side opposite to the protruding direction in the attached state. The second edge portion is located between the boundary between the abutment portion and the protrusion portion and the first edge portion when the label is viewed from the front in the attached state. The adhesive layer has an adhesive region in a region located between the boundary portion and an imaginary line that passes through an end portion of the second edge portion closest to the first edge portion and is parallel to the boundary portion when the label is viewed from the front in the attached state.

[0009] In the label according to the present disclosure, the paper material may be transparent. In the label according to the present disclosure, the second substrate includes an opposing surface facing the first substrate, and the opposing surface has a first region overlapping the first substrate at the protruding portion and a second region overlapping the first substrate at the abutting portion when the label is viewed from the front in the attached state. An adhesive portion that bonds the second substrate and the first substrate is provided between the first region and the first substrate. This material may have a non-adhesive portion between the second region and the first substrate that does not bond the second substrate and the first substrate, or a weakly adhesive portion having an adhesive strength weaker than that of the adhesive portion.

[0010] In the label according to the present disclosure, the first substrate has a third edge portion located in the protruding direction in the attached state. In this case, when the label is viewed from the front in the attached state, a center portion of the second edge portion in a direction parallel to the boundary may be located closer to the third edge portion than both ends of the second edge portion in the direction parallel to the boundary.

[0011] In the label according to the present disclosure, the back surface of the first substrate has a pair of corner regions on both sides in a direction parallel to the boundary on the first edge side when the label is viewed from the front in the attached state. In this case, the adhesive layer provided in the pair of corner regions may be subjected to a weak adhesion treatment so that the adhesive strength is weaker than that of the adhesive layer provided between the pair of corner regions, or may be subjected to a non-adhesive treatment.

[0012] A labeled adherend according to the present disclosure includes the label and the adherend. The label is attached to the adherend so as to include the contact portion that contacts the adherend and the protrusion that protrudes from the contact portion so as to be spaced apart from the adherend. Effect of the Invention

[0013] According to the present disclosure, there is provided an environmentally friendly label that can ensure sufficient shape retention, and a labeled object to which the label is affixed. [Brief description of the drawings]

[0015] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the embodiments described below, the same or common parts are denoted by the same reference characters in the drawings, and the description thereof will not be repeated.

[0016] (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. The labeled adherend 100 according to embodiment 1 will be described with reference to Figs. 1 and 2.

[0017] As shown in Fig. 1 and Fig. 2, a labeled adherend 100 according to an embodiment has a label 20 affixed to an adherend 10. The adherend 10 is, for example, a packaging box containing various items such as medicines, confectioneries, or cosmetics. The adherend 10 has a receiving surface 11 to which the label 20 is affixed, and a connecting surface 12 connected to the receiving surface 11. A ridge line 13 is formed at the boundary between the receiving surface 11 and the connecting surface 12. The receiving surface 11 has the ridge line 13 on one end side to which the connecting surface 12 is connected.

[0018] The label 20 is attached to the receiving surface 11 located near the ridge line 13. In an attached state in which the label 20 is attached to the receiving surface 11, a portion of the label 20 protrudes from the receiving surface 11 to the outside of the ridge line 13. In an attached state, the label 20 has a contact portion 31 that abuts against the adherend 10, and a protruding portion 32 that protrudes from the contact portion 31 so as to be separated from the adherend 10.

[0019] A design 15 is formed on the receiving surface 11. The label 20 is attached to the receiving surface 11 so that a first substrate 21, which will be described later, overlaps the design 15. In this embodiment, in a state in which the label 20 is attached to the receiving surface 11, the design 15 can be seen through the first substrate 21 (more specifically, the portion of the first substrate 21 exposed from the second substrate 22).

[0020] The label 20 includes a first substrate 21, a second substrate 22, an adhesive portion 231, a weakly adhesive portion 232, and an adhesive layer 24.

[0021] The first base material 21 has a front surface 21a and a back surface 21b, which are in a front-back relationship, as well as a first edge portion 21c and a third edge portion 21d. The first edge portion 21c constitutes an edge portion of the abutting portion 31 on the side opposite to the protruding direction in which the protruding portion 32 protrudes from the abutting portion 31 in the adhered state. The first edge portion 21c overlaps the adhered surface 11 in the adhered state. The third edge portion 21d is an edge portion of the first base material 21 located in the protruding 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 a direction parallel to the protruding direction.

[0022] The back surface 21b has a protruding region R3 and an overlapping region (abutment region) R4. The protruding region R3 protrudes outward from the ridge line 13 in the adhered state. The overlapping region R4 is located inside the ridge line 13 (on the adhered surface 11 side) in the adhered state and overlaps with the adhered surface 11. The overlapping region R4 abuts against the adhered surface 11 in the adhered state.

[0023] An adhesive layer 24 is provided on the back surface 21b for adhering the first base material 21 to the attachment surface 11. The adhesive layer 24 is made of, for example, a pressure-sensitive adhesive, a heat-sensitive adhesive, or the like.

[0024] In the protruding region R3, the adhesive layer 24 is provided over the entire surface, but the adhesive layer 24 provided in the protruding region R3 is provided with a non-adhesive treatment layer 25. This makes it possible to prevent the protruding region R3 from adhering to the connecting surface 12 even if the label 20 is bent toward the connecting surface 12.

[0025] In the overlap region R4, the adhesive layer 24 has at least an adhesive region in a region R5 located between a virtual line VL1 (see FIG. 3) that passes through an end portion of a second edge portion 22c of the second base material 22, which will be described later, that is located closest to the first edge portion 21c and is parallel to the boundary portion between the contact portion 31 and the protruding portion 32. In this embodiment, the boundary portion extends along the ridge line 13.

[0026] In this embodiment, the adhesive layer 24 is provided over the entire overlap region R4, and the adhesive layer 24 provided in the overlap region R4 is entirely adhered to the attachment surface 11. This allows the first base material 21 to be more stably attached to the attachment surface 11. Note that the adhesive layer 24 may be provided partially in the overlap region R4, as long as it has an adhesive region in at least a part of the region R5.

[0027] Since the first base material 21 occupies a large area of ​​the label, it is preferable that the first base material 21 is a thin, transparent base material made of plant-derived or natural materials, and when a paper material is used, the environmental load can be further reduced. The first base material 21 is more preferably made mainly of paper, and may be a laminate of paper and plant-derived materials.

[0028] As described above, the first base material 21 includes a paper material. 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, and more preferably has a haze value of 75% or less. The haze value is a value measured using an ultraviolet-visible spectrophotometer UV-2600 (manufactured by Shimadzu Corporation) and a haze meter NDH7000 (manufactured by Nippon Denshoku Industries Co., Ltd.).

[0029] Examples of paper materials having such a haze value include tracing paper and glassine paper. The haze value of tracing paper is greater than 75% and less than 99%, and the paper has semi-transparency. When such a semi-transparent paper material is used, the design 15 formed on the adhered surface 11 can be seen faintly through the paper in the adhered state. This gives the paper a sense of transparency.

[0030] On the other hand, the haze value of glassine paper is 75% or less, and it has transparency. Glassine paper is thinner and less stiff than tracing paper. When such a paper material with low stiffness is selected, the present invention can be suitably applied as described below. Furthermore, when glassine paper is used, the design 15 formed on the adhered surface 11 becomes more visible in the adhered state. In this case, a clearer sense of transparency can be given.

[0031] A paint for improving the transparency of the first base material 21 may be applied to the front surface 21a of the first base material 21. For example, a varnish may be used as the paint. For example, various known varnishes such as those using polyimide resin, polyester resin, or epoxy resin may be used as the varnish.

[0032] By applying paint to the front surface 21a, the smoothness of the front surface 21a is improved, which suppresses light scattering and improves transparency. For example, the haze value of the portion to which the paint is applied can be reduced to 55% or less.

[0033] The paint may be applied to the entire front surface 21a or to a part of it. The paint may also be applied to a portion of the first base material 21 where it is desired to improve the transparency. For example, the paint may be applied to the front surface 21a in a portion corresponding to the overlap region R4, or to the front surface 21a in a portion exposed from the second base material 22.

[0034] The paint may be applied before the second substrate 22 is adhered to the first substrate 21, or, if the paint is applied to the front surface 21a of the portion exposed from the second substrate 22, the paint can be applied after the second substrate 22 is adhered to the first substrate 21 or even after the label 20 is debonded from the substrate 10.

[0035] The compressive strength of glassine paper is smaller than that of the PET base material (K2411). The compressive strength is measured based on ISO12192, for example, using an AUTOGRAPH AG-X 500N (manufactured by Shimadzu Corporation). For example, the compressive strength of glassine paper is about 9 to 12 N, while the compressive strength of the PET base material (K2411) is about 20 to 23 N. Thus, glassine paper alone has almost no stiffness and is prone to bending and curling.

[0036] The second substrate 22 has a front surface 22a and a back surface 22b, which are in a back-and-forth relationship, and a second edge portion 22c. The second substrate 22 is disposed on the side of the front surface 21a of the first substrate 21. In the attached state, the second edge portion 22c is located on the opposite side to the protruding direction. In the attached state, the second edge portion 22c overlaps the attached surface 11. A design layer may be formed on the front surface 22a.

[0037] The back surface 22b of the second base material 22 functions as an opposing surface facing the first base material 21 (more specifically, the front surface 21a).

[0038] 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 above-mentioned attached state (when viewed along the stacking direction in which the first substrate 21 and the second substrate 22 are stacked), the first region R1 overlaps with the first substrate 21 at the protruding portion 32. The first region R1 protrudes outward beyond the ridge line 13. When the label 20 is viewed from the front in the above-mentioned attached state, the second region R2 overlaps with the first substrate 21 at the abutment portion 31. The second region R2 overlaps with the first substrate 21 inside the ridge line 13.

[0039] An adhesive portion 231 that bonds the second substrate 22 to the first substrate 21 is provided between the first region R1 and the first substrate 21. The adhesive portion 231 is made of, for example, a pressure-sensitive adhesive, a heat-sensitive adhesive, or the like.

[0040] Between the second region R2 and the first base material 21, a weakly bonded portion 232 having a weaker adhesive strength than the adhesive 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.

[0041] The weakly adhesive 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 performing a weak adhesive treatment entirely or partially on the adhesive portion formed entirely in the second region R2.

[0042] The weak adhesion treatment involves applying a surface treatment liquid, such as a liquid containing a release agent such as silicone resin (e.g., ultraviolet-curable ink) or a coating liquid containing fine particles (e.g., matte ink), to a predetermined area.

[0043] Note that, instead of the weakly adhesive portion 232, a non-adhesive portion that does not adhere the second base material 22 to the first base material 21 may be provided. 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 a treatment may be performed on the adhesive portion provided between the second region R2 and the first base material 21 to make it lose its adhesiveness.

[0044] The second base material 22 is stiffer than the first base material 21. That is, the second base material 22 has a greater compressive strength than the first base material 21.

[0045] As described above, the second substrate 22 may be made of plain paper, synthetic paper, metallized paper, gloss paper, synthetic resin film, or the like, as long as it is stiffer than the first substrate 21. As the synthetic resin film, for example, a polyolefin-based film such as polyethylene, polypropylene, cyclic olefin, or copolymer containing polyethylene, a polyester-based film such as polyethylene terephthalate, a polyamide-based film, or a polystyrene-based film may be used. In addition, when a substrate made of a plant-derived or natural material, or a paper material is used for the second substrate 22, the environmental load can be further reduced.

[0046] 3 is a front view of the label according to embodiment 1. The attached state of the label 20 will be described with reference to FIGS.

[0047] As shown in FIGS. 2 and 3, the adhesive layer 24 has an adhesive region at least in the region R5 as described above, and this enables the first base material 21 to be attached to the attachment surface 11.

[0048] When the label 20 is viewed from the front in the adhered state, 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 located between the boundary between the abutment portion 31 and the protrusion portion 32 and the first edge portion 21c.

[0049] Here, since the first base material 21 has little stiffness (almost no stiffness) as described above, the first base material 21 curls or falls over when used alone, but in this embodiment, the second base material 22, which is stiffer (has stronger stiffness) than the first base material 21, is layered on and adhered to the first base material 21. This allows the first base material 21 to be reinforced by the second base material 22.

[0050] At this time, since the second edge portion 22c is located between the boundary portion and the first edge portion 21c when viewed from the front, the first base material 21 can also be reinforced at the portion located at the abutting portion 31 (inside the ridge line 13) in the attached state. This makes the first base material 21 less likely to break at the boundary portion.

[0051] As a result, the label 20 according to the first embodiment can maintain a stable posture when attached, and can adequately ensure shape retention. Furthermore, since at least the first base material 21 contains a paper material, the burden on the environment can be reduced.

[0052] Furthermore, in the first embodiment, as will be described below, even if it is bent, it can be easily restored to an upright state.

[0053] Generally, when labeled adherends are packed in packaging material and transported during distribution, the portion of the label protruding from the adherend may be folded by being pressed by the inner surface of the packaging material, etc. In particular, when a paper material with low stiffness (almost no stiffness) is used as the base material, the paper material has a dead hold property, so once the paper material is folded, it is difficult for it to return to its original position.

[0054] In contrast, in the present embodiment, as will be described below with reference to Figures 4 to 6, even when a paper material is used for the first substrate 21, the bent label 20 can be easily returned to an upright state.

[0055] Fig. 4 is a side view showing a state in which the labeled adherend according to embodiment 1 is packaged and the label is bent. Fig. 5 is a diagram showing a state in which the bent label is restored in the labeled adherend according to embodiment 1. Fig. 6 is a diagram showing a state in which the bent label is restored in the labeled adherend according to embodiment 1.

[0056] 4, when the portion of the label 20 protruding from the adherend 10 is bent toward the connection surface 12 during distribution or the like, the second substrate 22 peels off from the first substrate 21 in the second region R2 because the adhesive strength of the weakly bonded portion 232 is weak as described above. This causes the position of the second substrate 22 to change without being folded. When the position of the second substrate 22 is changed, the second edge portion 22c side of the second substrate 22 protrudes outward from the connection surface 12 when the connection surface 12 is viewed from the front.

[0057] As shown in Figure 5, when returning the folded label 20 to an upright state, the portion of the second substrate 22 protruding outward from the connection surface 12 is pressed toward the attachment surface 11, as indicated by the arrow in the figure.

[0058] Here, the second substrate 22 is stiffer and more rigid than the first substrate 21. Therefore, when the portion of the second substrate 22 protruding outward from the connection surface 12 is pressed toward the attachment surface 11, the rigidity of the second substrate 22 is utilized to make the label 20 stand up as a whole, as shown in Fig. 6. Furthermore, when the label 20 is in the standing state, the portion of the second substrate 22 protruding outward from the connection surface 12 is again adhered to the weakly adhered portion 232. This allows the label 20 to maintain a more stable posture.

[0059] 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 an upright state.

[0060] Note that second edge portion 22c of second substrate 22 in embodiment 1 can be modified as in the following modified examples 1 to 5. Figures 7 to 11 are front views of the attached labels according to modified examples 1 to 5.

[0061] As shown in FIG. 7, in the label 20A according to the first modification, the second edge portion 22c has curved portions 22d on both sides in a direction parallel to the boundary portion between the abutting portion 31 and the protruding portion 32 (a direction parallel to the ridge line 13). The curved portions 22d are curved so as to approach the edge portion 22h of the second base material 22 located on the opposite side to the second edge portion 22c as they move outward in a direction parallel to the boundary portion. When the direction parallel to the boundary portion is the width direction of the second base material 22, the start point S1 of the curved portion 22d is located on both ends of the second edge portion 22c in the width direction rather than the center of the second edge portion 22c in the width direction. More specifically, the start point S1 of the curved portion 22d is located closer to both ends of the second edge portion 22c in the width direction.

[0062] As shown in FIG. 8, in label 20B of variant example 2, compared to label 20A of variant example 1, starting point S1 of curved portion 22d is located at a position approximately midway between the center of the second edge portion 22c in the width direction and each of both ends of the label 20 in the width direction.

[0063] 9, in a label 20C according to the third modification, the second edge 22c has inclined portions 22e on both sides in a direction parallel to the boundary. The inclined portions 22e are inclined toward an edge 22h of the second base material 22 located opposite the second edge 22c as they extend outward in a direction parallel to the boundary.

[0064] As shown in Fig. 10, in the label 20D according to the fourth modification, only both ends of the second edge 22c in the width direction are located closer to the first edge 21c than the boundary. The portions of the second edge 22c other than the both ends are substantially straight and located at substantially the same position as the boundary. The second edge 22c has curved portions 22f on both sides in the width direction. The curved portions 22f are curved so as to approach the first edge 21c as they move outward in a direction parallel to the boundary.

[0065] 11, in the label 20E according to the fifth modification, the second edge portion 22c has a plurality of protruding portions 22g. 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 an attached state. Each of the plurality of protruding portions 22g has, for example, a substantially semicircular or substantially semioval shape.

[0066] The shape of second edge portion 22c may be modified as in the above-described Modifications 1 to 5. Note that Modifications 1 to 5 are merely examples, and the shape of second edge portion 22c can be appropriately modified as long as second base material 22 has an area that overlaps first base material 21 on the side of first edge portion 21c of first base material 21 relative to ridge line 13 in the attached state. Even in this case, substantially the same effect as in embodiment 1 can be obtained.

[0067] (Embodiment 2) Fig. 12 is a front view of a labeled adherend according to embodiment 2. With reference to Fig. 12, a labeled adherend 100F according to embodiment 2 will be described.

[0068] 12, the labeled adherend 100F according to the second embodiment is different from the labeled adherend 100 according to the first embodiment in the shape of the second edge portion 22c of the second base material 22, and therefore in the shape of the adhesive layer 24 formed in the overlap region R4, as described later (see FIG. 13). The other configurations are almost the same.

[0069] The second edge portion 22c has a center portion P1 and both ends P2, P3 in a direction parallel to the boundary when the label 20 is viewed from the front in an attached state. The center portion P1 is located closer to the third edge portion 21d than the both ends P2, P3.

[0070] The position of center portion P1 may be located closer to protruding portion 32 than the boundary portion, may be located at a position overlapping with the boundary portion, or may be located closer to contact portion 31 than the boundary portion. In other words, center portion P1 may be located closer to third edge portion 21d than ridge line 13, may be located at a position overlapping with ridge line 13, or may be located closer to first edge portion 21c than ridge line 13.

[0071] In this case, at least a part of the second edge 22c is located between the boundary and the first edge 21c when the label 20F is viewed from the front in the attached state. When the center portion P1 is located at a position overlapping the boundary or closer to the abutment portion 31 than the boundary, the entire second edge 22c is located between the boundary and the first edge 21c.

[0072] In the second embodiment, the lines connecting the center portion P1 and both ends P2, P3 are linear, but the present invention is not limited to this. The lines connecting the center portion P1 and both ends P2, P3 may be curved, or may have a jagged or wavy shape, as appropriate.

[0073] Fig. 13 is a diagram showing the back surface side of the first base material in the label according to embodiment 2. With reference to Fig. 13, the adhesive layer 24 provided on the back surface 21b of the first base material 21 will be described.

[0074] As shown in FIG. 13, the back surface 21b of the first base material 21 has a pair of corner regions 26 on both sides in a direction parallel to the boundary when the label 20F is viewed from the front in an attached state.

[0075] The back surface 21b has points P4, P5, and P6 at positions corresponding to the center P1 and both ends P2 and P3 of the second edge portion 22c. The first edge portion 21c has start points P7 and P8 of a pair of corner regions 26. The pair of corner regions 26 refers to corner portion-containing regions of the first base material 21 that include the widthwise corner portion 27 located on the first edge portion 21c side, and in this embodiment, refers to the region surrounded by the line connecting points P4, P5, and start point P7, and the region surrounded by the line connecting points 4, 6, and start point P8.

[0076] Here, in the second embodiment, the adhesive layer 24 is provided on the entire back surface 21b. A non-adhesive treatment layer 25 is formed on the adhesive layer 24 provided in the region from the line connecting the points P4, P5, and P6 to the third edge portion 21d located on the opposite side to the first edge portion 21c.

[0077] Of the adhesive layer 24, the adhesive layer 24 provided in the region surrounded by the lines connecting the point P4, the starting point P7, and the starting point P8 has not been subjected to a non-adhesive or weak adhesive treatment and has normal adhesive strength. In other words, of the adhesive layer 24, the adhesive layer 24 provided between a pair of corner regions 26 has not been subjected to a non-adhesive or weak adhesive treatment.

[0078] Of the adhesive layer 24, the one provided in the pair of corner regions 26 is subjected to a weak adhesion treatment or a non-adhesive treatment so that the adhesive strength is weaker than that of the adhesive layer 24 provided between the pair of corner regions 26.

[0079] Even in this case, when the label 20F is viewed from the front in an attached state, the adhesive layer 24 has an adhesive area in a region R5 (see Figure 12) located between a virtual line VL1 (see Figure 12) that passes through ends P2, P3 of the second edge portion 22c that are closest to the first edge portion 21c and is parallel to the above-mentioned boundary portion and the above-mentioned boundary portion when viewed from the front in an attached state.

[0080] With such a configuration, the label 20 according to the second embodiment can also maintain a stable posture in an attached state, and can sufficiently ensure shape retention. Furthermore, since at least the first base material 21 contains a paper material, the burden on the environment can also be reduced.

[0081] Furthermore, by using the above-described shape of second edge portion 22c and the above-described configuration of adhesive layer 24, when a bag-shaped object or a container having a curved surface, such as a cylindrical container, is used as the adherend, it can be maintained in a more stable posture.

[0082] In addition, by shaping the second edge portion 22c as described above and providing the adhesive layer 24 as described above, it is possible to prevent a crease from being formed in the first substrate 21 when the label 20 is bent during transportation, etc., as will be described below.

[0083] 14 and 15 are a side view and a top view showing a labeled adherend according to the second embodiment in a bent state.

[0084] 14 and 15, when the label (protruding portion 32) protruding from the receiving surface 11 is bent, the adhesive layer 24 formed in the pair of corner regions 26 is subjected to a weak adhesion treatment or a non-adhesive treatment, so that the pair of corner regions 26 are not adhered to the receiving surface 11. Therefore, the bending stress acting on the label 20 can be released to the pair of corner regions 26.

[0085] Therefore, both ends P2, P3 of the first substrate 21 are raised from the attachment surface 11, and the central portion P1 of the first substrate 21 is bent to approach the ridge line 13 or the connection surface 12. Similarly, both ends (points P5, P6) of the second substrate 22 are raised from the attachment surface 11, and the central portion (point P4) of the second substrate 22 is bent to approach the ridge line 13 or the connection surface 12. This makes it possible to prevent the second substrate 22 from being folded to form creases. As a result, even if the label 20F is bent, it can be easily restored to an upright state.

[0086] The adhesive layer 24 in the second embodiment can be modified as in the following modified examples 6 and 7. Figures 16 and 17 are diagrams showing the back surface side of the first base material in the labels according to the sixth and seventh modifications.

[0087] 16, in the label 20G according to the sixth modification, a point P9 is on the line connecting the points P4 and P5, and a point P10 is on the line connecting the points P4 and P6. The points P9 and P10 are located symmetrically with respect to the center line of the first substrate 21. In this modification, a region surrounded by a line connecting the points P9, P5, and the starting point P7, and a region surrounded by a line connecting the points P10, P6, and the starting point P8 form a pair of corner regions 26.

[0088] The adhesive layer 24 is provided on the entire back surface 21b. A non-adhesive treatment layer 25 is formed on the adhesive layer 24 provided in the region from the line connecting the point P4 to the point P5 and the point P6 to the third edge portion 21d located on the opposite side to the first edge portion 21c.

[0089] Of the adhesive layer 24, the adhesive layer 24 provided in the region surrounded by the lines connecting point P4, point P9, starting point P7, starting point P8, and point P10 has not been subjected to non-adhesive or weak adhesive treatment and has normal adhesive strength. In other words, of the adhesive layer 24, the adhesive layer 24 provided between a pair of corner regions 26 has not been subjected to non-adhesive or weak adhesive treatment.

[0090] Of the adhesive layer 24, the one provided in the pair of corner regions 26 is subjected to a weak adhesion treatment or a non-adhesion treatment so that the adhesive strength is weaker than that of the adhesive layer 24 provided between the pair of corner regions 26. That is, the adhesive layer 24 provided in the region surrounded by the line connecting point P9, point P5, and starting point P7 and the region surrounded by the line connecting point P10, point P6, and starting point P8 is subjected to a weak adhesion treatment or a non-adhesion treatment.

[0091] Even in this case, when the label 20G is viewed from the front in an attached state, the adhesive layer 24 has an adhesive area in the area located between the boundary and a virtual line VL1 (not shown in Figure 16) that passes through the ends P2, P3 of the second edge portion 22c that are closest to the first edge portion 21c and is parallel to the boundary.

[0092] 17, the label 20H according to the seventh modification has points P11 and P12 on the first edge portion 21c, inside starting points P7 and P8. Points P9 and P10 are symmetrical with respect to the center line of the first substrate 21. In this modification, the area surrounded by the line connecting points P9, P5, and 11, and the area surrounded by the line connecting points P10, P6, and P12 form a pair of corner regions 26.

[0093] The adhesive layer 24 is provided on the entire back surface 21b. A non-adhesive treatment layer 25 is formed on the adhesive layer 24 provided in the region from the line connecting the point P4 to the point P5 and the point P6 to the third edge portion 21d located on the opposite side to the first edge portion 21c.

[0094] Of the adhesive layer 24, the adhesive layer 24 provided in the region surrounded by the lines connecting points P4, P9, P11, P12, and P10 has not been subjected to a non-adhesive or weak adhesive treatment and has normal adhesive strength. In other words, of the adhesive layer 24, the adhesive layer 24 provided between a pair of corner regions 26 has not been subjected to a non-adhesive or weak adhesive treatment.

[0095] Of the adhesive layer 24, the one provided in a pair of corner regions 26 is subjected to a weak adhesion treatment or a non-adhesion treatment so that the adhesive strength is weaker than that of the adhesive layer 24 provided between the pair of corner regions 26. That is, the adhesive layer 24 provided in the region surrounded by the lines connecting points P9, P5, and 11 and the region surrounded by the lines connecting points P10, P6, and P12 is subjected to a weak adhesion treatment or a non-adhesion treatment.

[0096] Even in this case, when the label 20H is viewed from the front in an attached state, the adhesive layer 24 has an adhesive area in the area located between the boundary and a virtual line VL1 (not shown in Figure 17) that passes through the ends P2, P3 of the second edge portion 22c that are closest to the first edge portion 21c and is parallel to the boundary.

[0097] In the sixth and seventh modifications, too, when the portion of the label (protruding portion 32) protruding from the receiving surface 11 is bent, the adhesive layer 24 formed in the pair of corner regions 26 is subjected to a weak adhesion treatment or a non-adhesive treatment, so that the pair of corner regions 26 are not adhered to the receiving surface 11. This allows the bending stress acting on the label 20 to be released to the pair of corner regions 26. As a result, substantially the same effect as in the second embodiment can be obtained.

[0098] In the above-mentioned second embodiment and the sixth and seventh modifications, the adhesive layer 24 formed in the pair of corner regions 26 is subjected to a weak adhesive treatment or a non-adhesive treatment, but the present invention is not limited to this. The adhesive layer 24 may not be provided in the pair of corner regions 26, so that the pair of corner regions 26 are non-adhesive.

[0099] In the above-mentioned first and second embodiments and first to seventh modifications, the adherend is a packaging box, but as long as the label has a contact portion and a protrusion when attached to the adherend, the adherend may be a bottle made of synthetic resin such as a PET bottle, a glass container, a soft blown container, a delaminated bottle, or a tube-shaped container. If the adherend is made of a paper material, a plant-derived material, or a material made of natural materials, the environmental load can be further reduced.
