Description

The present invention relates to a labeled container in which a label is attached to the container .

Conventionally, a label printed with a desired display has been attached to an article for purposes such as product name display, explanation display, or decoration.
Among these labels, a label having a foamed resin layer is also known (Patent Document 1).
Since a label having a foamed resin layer has a heat insulating property and a cushioning property, it is often used as a heat insulating label such as a container filled with a hot or cold object, or a damage preventing label such as a thin glass bottle.

  By the way, since the label having the foamed resin layer is relatively thick, the edge of the label is easily caught by foreign matter. For this reason, the edge part of the label affixed to the article may be peeled off.

[About labels]
In FIG. 1 thru | or FIG. 3, the label 1 of this invention has the label base material 2 and the adhesion layer 3 provided in the back surface.
The label base material 2 has a foamed resin layer 22 and may have other layers as necessary.
The pressure-sensitive adhesive layer 3 is a layer that serves as a medium for attaching the label substrate 2 to an adherend.
The end portion of the label base 2 is a thin portion 4 thinner than the other portions, and the edge of the thin portion 4 is inclined toward the back side of the label base 2.
Hereinafter, in contrast with the thin portion, another portion (region having the original thickness of the label base material) thicker than the thin portion may be referred to as a “thick portion”.

Specifically, the label base material 2 is formed in a predetermined shape in plan view. For example, as shown in FIG. 1, the outer shape of the label base 2 (label 1) is formed in a substantially rectangular shape in plan view. In addition, the planar view shape of the label base material 2 is not limited to this, Other square shapes, such as a substantially square shape and a substantially trapezoid shape, a substantially circular shape, a substantially elliptical shape, a substantially triangular shape, other polygonal shapes, etc. It may be formed (not shown).
The layer structure of the label substrate 2 includes a foamed resin layer 22 and a design print layer 24, and a non-foamed sheet layer 21 as necessary.

As shown in FIG. 2, the label substrate 2 is composed of a laminate in which a non-foamed sheet layer 21, a foamed resin layer 22, a skin layer 23, and a design print layer 24 are laminated in order from the lower side in the drawing.
The non-foamed sheet layer 21 may be provided on the surface of the skin layer 23 (or the surface of the foamed resin layer 22 when the skin layer 23 is not provided) or the foamed resin layer. 22 may be provided on the back surface of 22 and the surface of the skin layer 23, respectively. Further, the non-foamed sheet layer 21 may not be provided on the label substrate 2.
As shown in FIG. 2, the non-foamed sheet layer 21 is provided on the entire surface of the foamed resin layer 22. However, the non-foamed sheet layer 21 corresponds to a part of the surface of the foamed resin layer 22 (for example, a region corresponding to the thick part 5, or the whole thick part 5 and a part of the thin part 4. Or the like (not shown).

The non-foamed sheet layer 21 is not particularly limited, and examples thereof include synthetic resin sheets such as polyethylene terephthalate and polypropylene, paper, and synthetic paper. By providing the non-foamed sheet layer 21 on the foamed resin layer 22, the waist (rigidity) of the label substrate 2 can be increased.
The thickness of the sheet layer 21 is not particularly limited, but if it is too thick, the thin portion 4 will be relatively thick correspondingly. Considering this point, the thickness of the sheet layer 21 is preferably about 10 μm to 40 μm.

The material of the foamed resin layer 22 is not particularly limited, and examples thereof include olefins such as styrene, polyethylene, polypropylene, and cyclic olefin, and thermoplastic resins such as urethane. Among these, it is preferable to use a styrene resin. By forming the foamed resin layer 22 with a composition containing a styrenic resin, the inclined surface formed at the edge of the label substrate 2 is difficult to return to the original after being pressed by the pressing blade.
The foamed resin layer 22 may be composed of a foamed resin laminate in which two or more layers of the same or different materials are laminated, or a thin non-foamed layer between the two or more layers of the foamed resin. You may be comprised with the foaming resin laminated body in which the sheet | seat layer intervened (all are not shown in figure).
As the styrenic resin, general-purpose polystyrene (GPPS); styrene-butadiene copolymer; copolymer of maleic anhydride, acrylic acid ester, methacrylic acid ester and the like and styrene; or the like can be used. Among these, general-purpose polystyrene (GPPS) is preferable.

  The foaming method may be a known foaming method such as physical foaming or chemical foaming. Additives such as various fillers, plasticizers, and stabilizers can be appropriately added to these resins as necessary. The foamed resin layer 22 is obtained, for example, by extruding a resin composition such as polystyrene containing a foaming agent from a T die or an annular die at about 150 ° C. to 230 ° C., and performing a stretching treatment as necessary. be able to.

Further, the expansion ratio of the foamed resin layer 22 is not particularly limited, but is preferably about 2 to 10 times because it has appropriate heat insulation and cushioning properties, and further, while maintaining the bubbles in the thick portion 5. In order to make the foamed resin layer 22 easy to compress, about 2.5 to 7 times is more preferable. By using the styrene resin, the foamed resin layer 22 having a suitable foaming ratio can be formed relatively easily.
The thickness of the foamed resin layer 22 is not particularly limited, but if it is too thin, it does not have sufficient heat insulating properties and cushioning properties, so it is preferably 80 μm or more, more preferably 100 μm or more, and particularly preferably 120 μm. That's it. On the other hand, the upper limit of the thickness of the foamed resin layer 22 is not particularly limited, but if it is too thick (though depending on the foaming ratio and the material), the thin portion 4 cannot be formed effectively thin even if it is compressed. There is. Considering this point, the thickness of the foamed resin layer 22 is preferably 500 μm or less, and more preferably 400 μm or less.

The skin layer 23 is provided to smooth the surface of the foamed resin layer 22. The skin layer 23 can be formed by coextruding a skin layer forming material with a foamed resin when the foamed resin layer 22 is formed. Examples of the skin layer forming material include synthetic resin materials that do not contain a foaming agent. The synthetic resin material is not particularly limited. For example, the thermoplastic resin exemplified as the material for forming the foamed resin layer 22 can be used, but the skin layer 23 has the same kind of thermoplastic as the foamed resin layer 22. Resins are preferred. In particular, when the foamed resin layer 22 is formed of a styrene resin, the skin layer 23 is preferably formed of a styrene resin and an olefin resin.
However, when using the rough foamed resin layer 22 with air bubbles exposed on the surface, a thin sheet layer may be laminated on the surface of the rough foamed resin layer 22 as the skin layer 23.
By providing the skin layer 23, it becomes possible to print on it beautifully. That is, the display of the design print layer 24 can be clearly displayed on the surface side of the foamed resin layer 22. In addition, the skin layer may be provided on each of the front surface and the back surface of the foamed resin layer 22.
The thickness of the skin layer 23 is not particularly limited, and is generally about 5 μm to 15 μm.

The design print layer 24 is a layer on which a desired display such as a trade name is represented, for example. The design printing layer 24 is formed, for example, by applying ink by a known printing method such as gravure printing.
The design print layer 24 is provided on the entire surface of the skin layer 23 (or the foamed resin layer 22 when the skin layer 23 is not provided). But the design printing layer 24 may be provided in the one part area | region of the surface of the skin layer 23 (same foamed resin layer 22) (not shown).
The thickness of the design print layer 24 is not particularly limited, but is generally 3 μm to 5 μm.

The adhesive layer 3 is provided on the entire back surface of the label substrate 2.
The pressure-sensitive adhesive layer 3 can be provided in a solid shape by coating a pressure-sensitive adhesive on the back surface of the label substrate 2.
In the illustrated example, the adhesive layer 3 is provided on the entire back surface of the sheet layer 21.
But since the adhesive layer 3 should just be provided so that the label base material 2 can be stuck to articles | goods, it should just be provided in the whole back surface of the label base material 2. FIG. Examples of the case where the adhesive layer 3 is provided substantially over the entire back surface include a case where the adhesive is provided in countless dots in plan view and a case where the adhesive is provided in a fine mesh.
Since the adhesive layer 3 only needs to be provided so that the label substrate 2 can be attached to an article, the adhesive layer 3 is not limited to the case where the adhesive layer 3 is provided on the entire back surface or substantially the entire back surface of the sheet layer 21. Further, it may be provided annularly at the peripheral edge of the back surface of the sheet layer 21 or at both end portions of the back surface of the sheet layer 21.

As the pressure-sensitive adhesive, a known pressure-sensitive adhesive can be used. For example, a pressure-sensitive pressure-sensitive adhesive (pressure-sensitive adhesive without any heating or the like), a heat-sensitive pressure-sensitive adhesive (usually not sticky) However, the adhesive which shows adhesiveness by heating) etc. are mentioned.
When the pressure-sensitive adhesive is used to form the pressure-sensitive adhesive layer 3, the label 1 is usually provided by being temporarily attached to a release paper.
Although the thickness of the adhesion layer 3 is not specifically limited, For example, they are 10 micrometers-30 micrometers, Preferably they are 15 micrometers-25 micrometers.
The peel strength (adhesive strength) of the pressure-sensitive adhesive layer 3 is exemplified by about 2N / 25 mm to 30 N / 25 mm.
However, this peel strength is in accordance with JIS Z 0237: test material (tape provided with an adhesive layer): width 25 mm × length 100 mm, adherend (thing to which the tape is applied): flat made of polyethylene terephthalate It is a value measured in a peeling test under the conditions of a member, a peeling angle: 180 degrees, a peeling speed: 300 mm / min, and a temperature: 23 ° C.

A thin portion 4 is formed at the end of the label substrate 2. The thin portion 4 is a portion whose thickness is thinner than the other portion (thick portion 5) of the label substrate 2 where the thin portion 4 is not formed.
The thin portion 4 is provided in an annular shape in plan view over the entire circumference of the label substrate 2 (label 1).
The thin portion 4 can be formed, for example, by embossing or forming the foamed resin layer 22 with a high foam portion and a low foam portion (in this case, the low foam portion becomes a thin portion). For example, when embossing is performed on the end portion of the label substrate 2, the foamed resin layer 22 is compressed in the thickness direction, and the thin portion 4 is formed at the end portion according to the compression amount of the foamed resin layer 22. The thin portion 4 reaches the edge of the label substrate 2. In the thin portion 4, the foamed resin layer 22 is mainly compressed, but other layers may be compressed in the thickness direction slightly.

The thickness 4T of the thin portion 4 is not particularly limited, but if it is too thick, the effects of the present invention may not be sufficiently achieved. Considering this point, the thickness 4T of the thin portion 4 is preferably 0.7 times or less, more preferably 0.6 times or less, and particularly preferably 0.5 times or less of the thickness 5T of the thick portion 5. On the other hand, since there is a limit in making the foamed resin layer 22 thin, the thickness 4T of the thin portion 4 is preferably 0.2 times or more, more preferably 0.25 times or more the thickness 5T of the thick portion 5.
The thickness 5T of the thick part 5 is the sum of the thicknesses of the respective layers constituting the label substrate 2, and is, for example, 90 μm to 540 μm, preferably 120 μm to 400 μm, more preferably 150 μm to 300 μm. is there.
The width 4W of the thin-walled portion 4 is not particularly limited, but if the width 4W is too large, the region occupied by the thick-walled portion 5 is relatively narrow, and is preferably 10 mm or less, and more preferably 5 mm or less. On the other hand, since it is difficult to form the thin portion 4 having a too small width, the width 4W of the thin portion 4 is preferably 0.5 mm or more, and more preferably 1 mm or more.

Furthermore, the edge of the thin portion 4, which is the edge of the end of the label substrate 2, is an inclined surface 4 a that is inclined toward the back side of the label substrate 2. This inclination gradually decreases toward the back side of the label substrate 2 from the in-plane to the out-of-plane direction of the label substrate 2.
Here, the edge of the end of the label base 2 (the end of the thin portion 4) means a range from the edge of the label base 2 to the vicinity thereof, and the end of the label base 2 is the end. It means a range including the edge and closer to the surface of the label substrate 2 than that.
Although the width 4aW of the edge of the thin part 4 made into the inclined surface 4a is not specifically limited, For example, it exceeds 0 mm and is 2 mm or less, Preferably it is 0.01 mm-1 mm, More preferably, it is 0.03 mm-0 .5 mm.
The inclined surface 4a is formed over the entire edge of the thin portion 4 (the entire circumference of the label substrate 2).
The inclined surface 4a is preferably formed in a curved shape that bulges outward (curved shape that bulges outward when viewed in cross section, as shown in FIG. 2), in order to make it particularly difficult to get caught by foreign matter. However, although not particularly illustrated, the inclined surface may be formed in a flat surface shape (straight when viewed in a cross section).

[Label manufacturing method]
The label 1 of the present invention can be produced, for example, by the following procedure.
That is, the label 1 of the present invention is a pressing blade from one surface side of a raw material of a label having a base material having a foamed resin layer and an adhesive layer provided on the back surface of the base material. The label can be cut out from the label original and the edge of the label original can be inclined to the back side.
Preferably, before cutting with a pressing blade, a thin part is formed in a raw material of a base material by embossing.

FIG. 4 is a reference side view showing a label production line for cutting out a label from the original label.
In FIG. 4, reference numeral X denotes a label original, reference numeral 81 denotes a conveying roller, reference numeral 82 denotes an embossing roller, reference numeral 83 denotes a cutting roller having a pressing blade on the surface, and reference numeral 84 denotes , A receiving roller disposed opposite to each of the embossing roller 82 and the cutting roller 83 with the label original fabric X interposed therebetween, and reference numeral 85 denotes an unnecessary remaining portion collecting roll.

In this production line, the label original fabric X wound around the roll 86 is fed in the MD direction by the conveying roller 81, passed through the embossing roller 82, and a thin portion 4 having a predetermined pattern is formed in a predetermined region of the label original fabric X. Then, the label raw fabric X is cut into a label outer shape through a cutting roller 83 to form one label, and an unnecessary remaining portion Y of the label original fabric X remaining outside the label is wound around an unnecessary remaining portion collecting roll 85. .
This will be specifically described below.

Fig.5 (a) and FIG.6 (a) have shown the label original fabric before the process sent on the line.
The label original fabric X is composed of a substrate original fabric 6 and an adhesive layer 3 provided on the back surface thereof, and the adhesive layer 3 of the label original fabric X is temporarily attached to the release paper 7.
The label original fabric X in the illustrated example exemplifies a one-row cut-out type that can cut out one label in the short direction. Although a double-row cut-out type label raw material that can cut out two or more labels in the short direction can be used (not shown), here, a case where a single-row cut-out type label raw material X is used is used. Let's take an example. A label is manufactured from a double-column cut-out type label raw material, but may be performed in the same manner as the single-row cut-out type.

In the case where a plurality of labels are manufactured mechanically and continuously, a long label original fabric X is used.
The long label original X is in the form of an elongated tape whose length in the longitudinal direction is 10 times or more the length in the short direction. In this case, in order to affix the label original fabric X, the release paper 7 is also long.
The layer structure of the base material 6 is the same as that of the label base 2, and the base material 6 is, for example, as shown in FIG. And a laminated body in which a foamed resin layer 22, a skin layer 23, and a design printing layer 24 are laminated.
When the adhesive layer 3 is a heat-sensitive adhesive, the label original fabric X does not have to be laminated on the release paper 7.

As shown in FIG. 4, the surface of the label original fabric X is pressed by an embossing roller 82 on which convex portions having a predetermined pattern are formed. By this pressing, a region including the entire circumference of the end of one label is compressed, and a thin portion 4 having a predetermined pattern surrounding the thick portion 5 is generated (see FIGS. 5B and 6B). ). The thick portion 5 and the thin portion 4 are formed at predetermined intervals in the longitudinal direction of the label original fabric X.
In the embossing process, when the embossing roller 82 heated at a surface temperature of 100 ° C. to 130 ° C. is pressed, the thin part 4 having a predetermined thickness can be easily formed with relatively little return.

Next, as shown in FIG. 4, from the surface side of the label original fabric X, a cutting roller 83 having a pressing blade is applied, and at least the base material original 6 of the label original fabric X is cut in the thickness direction. One label 1 is cut out from X, and the unnecessary remaining portion Y of the label original X remaining on the outside of the label 1 is wound around the unnecessary remaining portion collecting roll 85. FIG. 5C and FIG. 6C show the original label X after the unnecessary remaining portion Y is removed.
For example, a pinnacle blade can be used as the pressing blade.

FIG. 7 is a cross-sectional view showing a state when the pressing blade is applied to the label original.
In FIG. 7, the cutting roller 83 and the receiving roller 84 shown in FIG. 4 are omitted.
The pressing blade 86 includes a base portion 861 and a blade edge 862 that protrudes downward from the base portion 861.
The tip of the blade edge 862 of the pressing blade 86 is formed at an acute angle, and the length (blade length) of the blade edge 862 of the pressing blade 86 is set to be equal to or greater than the thickness of the base material 6.
Both side surfaces of the blade edge 862 of the pressing blade 86 are inclined so as to form an acute angle with respect to the vertical direction with reference to the vertical direction with respect to the surface of the label original fabric X. The inclination angle (inner angle formed by the vertical direction and the side surface) is, for example, in the range of 5 to 75 degrees, preferably more than 20 degrees and 75 degrees or less, and more preferably 25 degrees to 60 degrees. Especially preferably, it is 30 to 50 degrees.

In the illustrated example, both side surfaces of the blade edge 862 of the pressing blade 86 are inclined as described above. However, although not particularly illustrated, one side surface of the blade edge 862 (for example, the end of the label base material to be cut out) Only the surface in contact with the edge may be inclined (may be an inclined surface).
Of the two side surfaces of the blade edge 862, the surface in contact with the edge of the label base material to be cut out is an inclined surface, so that when the pressing blade 86 is pressed, the edge of the label base material to be cut out is pushed downward. The edge can be favorably inclined toward the back side of the label substrate.

Furthermore, in the illustrated example, both side surfaces of the blade edge 862 (each inclined surface on both side surfaces) are two-step inclined with different inclination angles. This two-step inclination may be only on the one surface of the cutting edge 862. The first inclined surface 862a is formed on the tip end side, and the second inclined surface 862b is formed continuously above the first inclined surface 862a. The inclination angle α of the first inclined surface 862a on the tip end side (inner angle formed by the vertical direction and the first inclined surface 862a) is preferably 5 degrees to 25 degrees, and more preferably 8 degrees to 20 degrees. The inclination angle β of the second inclined surface 862b (inner angle formed by the vertical direction and the second inclined surface 862b) is preferably 25 to 75 degrees, and more preferably 30 to 60 degrees.
As described above, since at least one surface of the blade edge 862 is inclined in two steps, when the pressing blade 86 is pressed, the edge of the label 1 to be cut out can be inclined in a favorable curved shape.

  In the illustrated example, a ridge line exists between the upper end of the first inclined surface 862a and the lower end of the second inclined surface 862b, but the ridge line between the upper end of the first inclined surface 862a and the lower end of the second inclined surface 862b. You may use the press blade 86 which does not have (not shown). In other words, in the illustrated example, the first inclined surface 862a and the second inclined surface 862b are continuously formed with an obtuse angle portion, but the upper end of the first inclined surface 862a and the lower end of the second inclined surface 862b are gentle. A pressing blade 86 continuously formed with a curved surface may be used. Thus, when the 1st inclined surface 862a and the 2nd inclined surface 862b have a curved surface, the upper part of the 1st inclined surface 862a has the inclination angle upward (the lower end of the 2nd inclined surface 862b). It is preferable that the curved surface gradually increases as it goes to.

The pressing blade 86 is applied to the label original fabric X so that the blade edge 862 is pushed down in a substantially vertical direction with respect to the surface of the label original fabric X.
A single label 1 as shown in FIG. 1 to FIG. 3 can be cut out from the label original fabric X by pushing the entire substrate original fabric 6 in the thickness direction by the pressing blade 86. In addition, the inclined surface 4 a is formed at the edge of the thin portion 4 simultaneously with the pressing.

  After that, by removing the unnecessary remainder Y, a continuous label body in which a plurality of labels 1 are arranged at predetermined intervals in the longitudinal direction of the release paper 7 is obtained as shown in FIG.

[Examples of label use]
The label 1 of the present invention is used by being attached to an adherend through an adhesive layer 3.
The adherend is not particularly limited, and examples thereof include various containers such as beverage containers, food containers, and cosmetic containers, packaging boxes such as food packaging cases, and articles such as stationery.
FIG. 8 shows an adherend with a label (a container with a label) formed by attaching the label of the present invention to a beverage container.
The beverage container 9 (adhered body) has a cylindrical body 91 such as a cylinder, and the label 1 is attached so as to be wrapped around the body 91.

The affixing form of the label 1 is not particularly limited. For example, the label 1 may be affixed so that one end of the label 1 overlaps the other end or the thick part 5, or the label 1 The label 1 may be affixed so that both ends are in contact with or close to each other, or the label 1 may be affixed in a state where both ends of the label 1 are sufficiently separated. The end portion of the label 1 is synonymous with the end portion of the label substrate 2.
In the example shown in FIG. 8, the label 1 is stuck on the first end 1a of the label 1 with the second end 1b overlapped so that the ends of the label 1 overlap each other. The first end 1a and the second end 1b are opposite ends.

  In this case, as shown in FIG. 9, it is preferable to stick the label 1 so that the thin portion 4 of the second end 1b overlaps the thin portion 4 of the first end 1a of the label 1. That is, the edge of the second end 1b (the edge of the second end 1b exceeds the edge of the first end 1a and does not reach the thick part 5 adjacent to the thin part 4 of the first end 1a). It is preferable that the label 1 is affixed so as to be within the range of the thin portion 4 of the first end 1a. Alternatively, the first end 1a and the second end 1b of the label 1 are not overlapped, but the label 1 is arranged so that the edge of the first end 1a of the label 1 and the edge of the second end 1b are in contact with or close to each other. It is also a preferred embodiment when is attached. In order to apply the label 1 in this way, the label 1 may be designed in consideration of the circumference of the adherend.

In the label 1 of the present invention, the end portion of the label substrate 2 is a thin portion 4, and the end edge of the thin portion 4 is an inclined surface 4 a inclined toward the back side of the label substrate 2. When such a label 1 is affixed to an adherend 9 such as an article, the edge of the label 1 has a relatively small degree of protrusion from the adherend of the label 1 and the edge is not angular. Can be prevented from being caught by foreign matter.
In particular, as shown in FIG. 9, the thin end 4 of the second end 1b overlaps the thin end 4 of the first end 1a of the label 1, or the first end 1a of the label 1 is not shown. The labeled container to which the label 1 is attached so that the edge of the second end 1b is in contact with or close to the edge of the second end 1b can effectively suppress the edge of the label 1 from being caught by a foreign object.

[About labels and manufacturing methods thereof according to other embodiments]
In addition, the label of this invention and its manufacturing method are not limited to the said embodiment, A design can be variously changed in the range which this invention intends.
Hereinafter, although other embodiment is described, about the structure and effect similar to the said embodiment, the description is abbreviate | omitted and a term and a code | symbol are used as it is.

  In the label of the above embodiment, the thin portion 4 is formed on the entire periphery of the label substrate 2, but the thin portion 4 may be formed on a part of the periphery of the label substrate 2. For example, as shown in FIG. 10, the first end 1 a and the second end 1 b of the label 1 (label base material 2) are thin-walled portions 4 (the edges are inclined like the above embodiment). And the third end portion 1c and the fourth end portion 1d may be the thick portion 5.

  Moreover, in the label of the said embodiment, although the thin part 4 is formed only in the edge part of the label base material 2, one or some thin part 4 of the label base material 2 is as needed. It may be formed in a plane (in a region corresponding to the thick portion 5 in the above embodiment) (not shown). The thin portion 4 formed in the surface of the label base 2 is mainly formed for decoration purposes.

  Moreover, in the manufacturing method of the label of the said embodiment, although embossing is implemented, this embossing can also be abbreviate | omitted. For example, when forming the foamed resin layer 22, by suppressing the degree of foaming in the region corresponding to the thin portion 4 of the label base material 2 more than the region corresponding to the thick portion 5, A label original fabric X on which a thin portion 4 having a predetermined pattern is formed is prepared. As shown in FIG. 1 and FIG. 2, when the label original fabric X in which the thin portion 4 is formed on the substrate original fabric 6 is used, the pressing blade 86 pushes it out without performing the embossing. Such a label 1 can be manufactured.

Further, in the method for producing a label of the present invention, the base material 6 having a uniform thickness (see FIG. 5) without performing the thin-walled portion forming step (steps such as embossing and partially suppressing the degree of foaming). The label 1 may be cut out from the label original fabric X by pressing the pressing blade 86 against the substrate original fabric 6 (a).
As shown in FIG. 11, the label 1 obtained by the other manufacturing method does not have a thin portion at the end of the label base material 2, but is pressed by the pressing blade 86. As described above, the edge of the label base 2 is an inclined surface 4 a that is inclined toward the back side of the label base 2.
In such a label 1 as well, since the edge of the label substrate 2 is inclined, the edge of the label 1 is not angular, and the edge of the label 1 can be suppressed from being caught by a foreign object.

In the label manufacturing method of the above-described embodiment, the pressing blade 86 cuts only the base material 6 in the thickness direction. However, using a pressing blade having a long blade length, the base material and release paper ( You may change so that the whole label original fabric may be cut | disconnected in the thickness direction (not shown).
Further, in the label manufacturing method of the above embodiment, the pressing blade 86 is provided on the surface of the cutting roller. However, the pressing blade 86 is provided on the surface of the plate-like member without using the cutting roller, and the plate-like member. May be moved up and down to push out the base material 6 and the like (not shown).
