The example bottle 90 includes a head 91, a neck 92, a body 93, and a bottom 94. . FIG. 4 is a schematic perspective view illustrating a state in which the label 10 according to an embodiment of the present disclosure is mounted on the neck 92 of the bottle 90, and the first surface 10a of the label 10 is entirely the head of the bottle 90. The second surface 10b of the label 10 is arranged on the body 93 side of the bottle 90 as a whole. The neck 92 of the bottle 90 is sandwiched between the locking portions 11 and 12 of the label 10. The half opening of each of the locking portions 11 and 12 corresponding to the divided portion of the opening 15 is engaged with the neck 92 of the bottle 90. FIG. 5 is a schematic cross-sectional schematic view of the label 10 according to an embodiment of the present disclosure, schematically illustrating a cross-section along the dashed-dotted line VV in FIG. 1, formed on the sheet body 10j of the label 10. The cutting line 21 and the outer peripheral wall surface 10c that defines the contour of the sheet body 10j are shown. FIG. 6 is a schematic enlarged view of a dotted circle designated by reference numeral VI in the schematic cross-sectional view of FIG. 5, and shows that the cut line 21 is defined between the pair of wall surfaces 25. FIG. 7 is a schematic enlarged view of a dotted-line circle designated by reference numeral VII in the schematic cross-sectional view of FIG. 5, showing an outer peripheral wall surface 10c of the seat body 10j. FIG. 8 shows a difference between the maximum distance L1 and the minimum distance L2 from the reference position FP set on the mounting surface 9 to a certain height from the mounting surface 9 to the first surface 10a of the label 10. It is a schematic diagram which shows that the absolute value of the value L3 can be calculated.

  As can be best seen from FIGS. 1 to 8, and in particular from FIG. 5, in some cases the label 10 comprises a sheet body 10j having a first side 10a and a second side 10b opposite the first side 10a, and a sheet body. 10j has at least one score line 21 or 22 formed therein. At least one score line 21, 22 extends to at least partially define at least one stop 11, 12 for preventing release of label 10 from neck 92 of bottle 90. Further, at least one cut line 21, 22 penetrates between the first surface 10a and the second surface 10b of the sheet body 10j. Since the label 10 is attached to the neck 92 of the bottle 90, it can be called a neck POP label.

  The sheet body 10j of the label 10 is made of various materials as long as it can be attached to the bottle 90. For example, paper, synthetic paper, polyolefins such as PP (polypropylene) and PE (polyester), and PET (polyethylene terephthalate) ) And synthetic resin sheets such as PS (polystyrene) and PA (polyamide). Preferably, the label 10 is made of paper. In some cases, the thickness of the sheet body 10j is 50 μm to 300 μm, or 100 μm to 200 μm. Regardless of the type of material of the label 10, the label 10 may be warped due to the effects of the score lines 21 and 22 formed therein. In some cases, the label 10 and / or the sheet body 10j is made of paper and can absorb humidity in the air and expand or contract. In some cases, the first surface 10a is a first printing surface, and the second surface 10b is a second printing surface different from the first printing surface. When the sheet body 10j is made of paper and the first surface 10a and the second surface 10b of the sheet body 10j are different printing surfaces, different physical states exist on the front and back of the sheet body 10j. In some cases, the first side 10a is a color printing side and the second side 10b is a non-color printing side. For example, on the first surface 10a of the label 10 illustrated in FIG. 1, a star colored in yellow is drawn on a black background. On the other hand, on the second surface 10b of the label 10, a URL, a two-dimensional barcode, a description of a product to which the label 10 is attached, and detailed information of a campaign for the product to which the label 10 is attached are described. Although an example of a color printing surface on which stars are drawn has been presented to promote understanding, various designs utilizing characters and celebrities can be applied to the color printing surface for effective sales promotion. Characters designed as a substitute for or in addition to pictures can also be printed on the color printing surface.

  As a printing method for the first and second surfaces 10a and 10b of the sheet body 10j, for example, a flat plate printing method (such as offset printing), an intaglio printing method (such as engraved intaglio printing or gravure printing), a stencil printing method ( Silk screen printing) can be used, but the present invention is not limited to these. Examples of the printing ink include an ink in which a colorant is dispersed in a resin such as acrylic or cellulose. As the coloring agent, inorganic pigments (titanium oxide, carbon black, copper, etc.), pearl pigments, and aluminum powder can be used. The thickness of the printed layer of a picture or a character can be, for example, 0.5 μm to 10 μm, or 1 μm to 3 μm.

In some cases, a varnish layer may be formed on the first and / or second surfaces 10a, 10b of the sheet body 10j to provide slip and abrasion resistance. The material of the varnish layer is appropriately selected in consideration of the production method, slipperiness, glossiness, light transmittance, design, and the like. The material of the varnish layer can be, for example, OP varnish, oil varnish, aqueous varnish, UV curable varnish, or other special varnish. Preferably, a UV-curable varnish is used. Further, an auxiliary agent such as a photocurable resin, a photosensitive monomer, rosin, and an organic solvent may be added to the varnish layer. Preferably, the varnish layer is translucent and may be transparent or translucent so as not to impede the transmission of information by the printed picture / character. It is also envisioned that multiple varnish layers are stacked. The thickness of the varnish layer can be, for example, 0.5 μm to 10 μm, more preferably 1 μm to 3 μm, but is not limited thereto.
The varnish layer can be partially provided to such an extent that the slip property can be ensured. For example, a varnish layer can be selectively formed in a region where a transport roll 835 of the second device 800 described later contacts. The varnish layer can uniformly cover one surface of the sheet body 10j, but is not limited thereto, and is formed on one surface of the sheet body 10j as a dot-shaped array. The area ratio at which the varnish layer covers the sheet body 10j is, for example, 10% or more, and more preferably 30% or more.

  The color of the sheet body 10j is, for example, white, gray-white, gray, or the like, and alternatively or additionally, the sheet body 10j has translucency. A mode in which both the sheet body 10j and the varnish layer are transparent or translucent, and the label 10 is transparent or translucent is also conceivable. Preferably, inert inorganic fine particles are contained in the varnish layer on the sheet body 10j for adjusting the slipperiness. The inert inorganic fine particles include at least one selected from silica, calcium carbonate, and silicone particles, and the content thereof is, for example, 1 to 10% by mass in terms of the solid content ratio of the varnish layer.

  The number of cut lines 21 and 22 provided on one label 10 and the manner in which the cut lines 21 and 22 extend are various, and are not limited to those in the illustrated example. As shown in FIGS. 1 and 2, in some cases, a pair of score lines 21 (which may be referred to as first (or vertical) score lines) extending along the length of the label 10 and the width of the label 10. One cut line 22 (which may be referred to as a second (or horizontal) cut line) extending between the pair of cut lines 21 and connecting the two may be formed in the sheet body 10j of the label 10. Label 10 has a length L10 and a width W10. Length L10 ≧ width W10 is satisfied, or length L10 ≦ width W10 is satisfied. The outline shape of the label 10 may be a circular shape, a chamfered or non-squared polygonal shape, but various other shapes and a star shape are envisioned.

  In some cases, a pair of locking portions 11 and 12 are defined from the pair of cut lines 21 and one cut line 22 described above. When the opening 15 is provided, a pair of cut lines 21, one cut line 22, and a pair of locking portions 11 and 12 are defined from the opening 15. The label 10 may have an outer peripheral portion 13 surrounding the pair of locking portions 11 and 12 in addition to the pair of locking portions 11 and 12. The outer peripheral portion 13 includes a pair of label ends 131 located at both ends in the length direction of the label 10 and a pair of rod portions 132 extending between one and the other label ends 131 along the length direction of the label 10. Have.

  In some cases, the score lines 21 and 22 formed in the sheet body 10j of the label 10 are discontinuous in the extending direction. In some cases, an opening 15 is formed in the sheet body 10j, and the cut line 22 is divided by the opening 15. Referring to FIG. 2, one cut line 21 on the left side is divided and discontinuous at first to third points P1 to P3, and the other cut line 21 on the right side is divided into fourth to fourth lines. The portion of the cut line 22 that is cut off at six points P4 to P6 and is discontinuous at the left side of the opening 15 is the portion of the cut line 22 that is cut off at the point P7 and is discontinuous at the right side of the opening 15. Is discontinuous at the point P8. The first to eighth locations P1 to P8 have no cut lines or cut lines that do not pass through between the first surface 10a and the second surface 10b of the sheet body 10j. Such first to eighth points P1 to P8 may be referred to as dividing parts for dividing the cut lines 21 and 22.

  In some cases, the score lines 21 and 22 are formed such that a pair of locking portions 11 and 12 are arranged along the length direction of the label 10 and / or each end 21 a of the score line 21. 21b inclines inward in the width direction of the label 10. As a variation, the opening 15 is omitted and / or a discontinuous score line defining the opening 15 is formed, so that the opening 15 is formed when the label 10 is attached to the bottle 90. The opening 15 may be a polygon other than an elliptical shape (a triangle, a square, a pentagon, etc.).

  The object to which the label 10 is attached can be various types of bottles 90. Bottle 90 may be made of glass, plastic, or other materials. Bottle 90 may be a container of various liquids such as soft drinks and alcoholic beverages. Bottle 90 may be a container for industrial chemicals or deleterious liquids. That is, the type of liquid to be injected into the bottle 90 is arbitrary, and there is no limitation on the type. The bottle 90 has a head 91, a neck 92, a trunk 93, and a bottom 94 in some cases. The head 91 of the bottle 90 is formed by an upper opening of the bottle main body, or is formed by coupling the upper opening with a cap. The head 91 of the bottle 90 can be a portion that is amplified and / or enlarged in diameter than the neck 92 of the bottle 90. Like the head 91, the body 93 of the bottle 90 may be a portion that is amplified and / or enlarged in diameter than the neck 92 of the bottle 90.

  As can be seen from FIG. 4, when the label 10 is applied to the neck 92 of the bottle 90, depending on the score line formed in the label 10, the first surface 10a of the label 10 may be wholly or partially. The label 90 is disposed on the head 91 side of the bottle 90, and the second surface 10 b of the label 10 is disposed entirely or partially on the body 93 side of the bottle 90. When a cut line is formed as in Patent Document 2 (Japanese Patent Application Laid-Open No. 2007-320600), the first surface 10a of the label 10 is partially arranged on the head 91 side of the bottle 90, and the second surface of the label 10 The surface 10 b is partially arranged on the body 93 side of the bottle 90.

  When the label 10 is attached to the neck 92 of the bottle 90, each of the pair of locking portions 11 and 12 comes into contact with the neck 92 of the bottle 90, and the label 10 may come off from the neck 92 of the bottle 90. Will be blocked. In some cases, the bottle 90 has a flange 95 provided between the head 91 and the neck 92, and the flange 95 of the bottle 90 and the locking ends 11a, 12a of the locking portions 11, 12 interfere with each other. As a result, an attempt to push the label 10 attached to the bottle 90 toward the head 91 and remove the label 10 from the neck 92 is frustrated. When the label 10 is made of paper, there is an advantage that when the purchaser of the bottle 90 drinks the beverage in the bottle 90, the label 10 attached to the bottle 90 can be easily broken by hand and removed. Each lock 11, 12 has a suitable length in the length direction of the label 10, so that the head 91 of the bottle 90 can be moved (via pivotal movement of the locks 11, 12). 10 can be smoothly penetrated. In some cases, the label 10 is provided with an oval-shaped opening 15 having a minor diameter smaller than the diameter of the head 91 of the bottle 90 so that the head 91 of the bottle 90 can penetrate the label 10 smoothly, And stable attachment of the label 10 to the neck 92 of the camera. The major axis of the elliptical opening 15 may have a length near the diameter of the head 91 of the bottle 90.

  As can be clearly understood from FIG. 5, in some cases, the sheet body 10j of the label 10 slightly warps. The degree of warpage of the label 10 may depend on various factors such as the laminated structure of the sheet body 10j, the material of the sheet body 10j, the thickness of the sheet body 10j, and / or the groove width, number and extension of the cut lines. . The label 10 used for labeling the bottle 90 is strongly required to be inexpensive, and therefore, a solution as simple as possible is desired.

  As shown in FIGS. 5 and 6, in some cases, the score lines 21 and 22 have a first width W1 on the first surface 10a side and a first width W1 larger than the first width W1 on the second surface 10b side. It has two widths W2, the first surface 10a is convex, and the second surface 10b is concave. According to the study by the inventors of the present application, it has been clarified that the variation in the direction and degree of the warpage of the label 10 can be reduced by making a cut line from the second surface 10b side of the sheet body 10j. Since the first surface 10a of the label 10 is a surface on which characteristic information and / or a picture is presented more than the second surface 10b, it is easy to check whether the cutting position is correct or not. It is common to draw lines. The inventors of the present application have found that the variation in the direction and degree of warpage of the label 10 is reduced by a method different from such a general practice, and a decrease in the operation rate of the labeling device is avoided or suppressed by such a simple method. I found something new.

  In some cases, as can be seen from FIG. 6, the score lines 21 and 22 are defined between the pair of wall surfaces 25, and the cut lines 21 and 22 are formed between the wall surface 25 and the second edge rather than the first edge 28 between the wall surface 25 and the first surface 10a. The second edge 29 between the surfaces 10b is gentler. In some cases, the groove widths of the cut lines 21 and 22 may be tapered from the second surface 10b side toward the first surface 10a side.

  In some cases, as can be seen from FIG. 7, the label 10 has an outer peripheral wall 10c that defines the contour of the sheet body 10j, and the outer peripheral wall 10c is closer than the third edge 26 between the outer peripheral wall 10c and the first surface 10a. The fourth edge 27 between the second surfaces 10b is gentler. In some cases, the sheet preform 1 has a score line 24 defining the contour of each label 10 and at least one engagement within each label 10 to prevent release of the label 10 from the neck 92 of the bottle 90. At least one score line 21, 22 extending to at least partially define the stops 11, 12 is formed in the same step. The relative positions of the cut lines 24 and the cut lines 21 and 22 become constant, and the deterioration of the uniformity of the warpage of the label 10 can be suppressed.

  The method of evaluating the degree of warpage occurring on the label 10 is performed based on the following description made with reference to FIG. In FIG. 8, the label 10 is placed on the placement surface 9. At this time, the second surface 10b of the label 10 comes into contact with the mounting surface 9 and faces again. The first surface 10a of the label 10 faces the opposite side to the mounting surface 9, that is, the reference position FP side. More specifically, the first surface 10a of the label 10 is the upper surface in the vertical direction, and the second surface 10b is the lower surface in the vertical direction. The reference position FP is set at a certain height from the mounting surface 9 on which the label 10 is mounted. The maximum distance L1 from the reference position FP to the first surface 10a of the label 10 is measured by various methods. Similarly, the minimum distance L2 from the reference position FP to the first surface 10a of the label 10 is measured by various methods. The fact that the absolute value of the difference value L3 between the maximum distance L1 and the minimum distance L2 is small means that the degree of warpage generated in the label 10 is small. In some cases, the absolute value of the difference value L3 is 0.6 mm or 0.55 mm or less. In this regard, the thickness of the sheet body 10j of the label 10 is 50 μm to 300 μm, or 100 μm to 200 μm, and the label 10 is made of paper. The mounting surface 9 can be a flat surface or a non-flat surface.

  As shown in FIG. 8, when the first surface 10a of the label 10 is convex, the minimum distance L2 is usually measured at the center of the label 10, and the maximum distance L1 is measured at the outer periphery of the label 10. Conversely, if the first surface 10a of the label 10 is concave, the minimum distance L2 is measured at the outer periphery of the label 10, and the maximum distance L1 is measured at the center of the label 10. For this reason, the difference value L3 indicates a negative value (L2−L1) when the first surface 10a of the label 10 is convex with respect to the center of the first surface 10a of the label 10, and the first value of the label 10 When the surface 10a is concave, it indicates a positive value (L1-L2).

  Next, a method and a system for continuously attaching the above-described sheet label 10 to the neck 92 of the bottle 90 will be described. FIG. 9 shows a first device 700 that forms a plurality of labels 10 by forming cut lines 21, 22, 24 using a blade 723 on the sheet preform 1 and removes each label 10 from the sheet preform 1. FIG. 10 shows that the cut lines 21, 22, and 24 are formed in the sheet preform 1 by the roll 721 provided with the blade 723 on the outer periphery. FIG. 11 shows a second apparatus 800 for selectively feeding out one label 10 from a stack of a plurality of labels 10 taken out of the sheet base material 1 and attaching the label 10 to the neck 92 of the bottle 90. FIG. 12 shows a state in which the labels 10 are stacked in the second device 800. In some cases, the blade 723 is a double blade that tapers in width from both sides toward the cutting edge. The blade 723 is not a single blade that gradually narrows from one side toward the blade edge.

  In the first device 700, a plurality of labels 10 are formed by forming the cut lines 21, 22, 24 using the blade 723 on the sheet preform 1, and each label 10 is taken out from the sheet preform 1. In some cases, the first device 700 includes a storage unit 710 that stores the sheet preforms 1 in a stacked state, and a cut that forms a score line in one sheet preform 1 that is selectively supplied from the storage unit 710. It may have a line forming part 720 and a label take-out part 730 that takes out the label 10 from the sheet preform 1 in which the cut line is formed. The first device 700 includes a pair of rolls 721 and 722 in which a blade 723 is provided on the outer circumference of one roll 721 as a score line forming unit 720. The sheet preform 1 is supplied between the pair of rolls 721 and 722, and cut lines 21, 22 and 24 are formed in the sheet preform 1. In some cases, a cut line sufficient to remove the label 10 from the sheet preform 1 is formed in the sheet preform 1 in a single step in order to suppress variations in the direction and degree of warpage of the label 10. That is, when the sheet preform 1 passes between the pair of rolls 721 and 722, the sheet preform 1 is provided with a cut line 24 defining the outline of each label 10 and a neck 92 of the bottle 90 within each label 10. At least one score line 21, 22 is provided which extends to at least partially define at least one stop 11, 12 for preventing release of the label 10 from the label. There are various methods for removing the label 10 from the sheet preform 1, for example, selectively removing the label 10 from the remaining portion of the sheet preform 1 by air. The label 10 separated from the rest of the sheet preform 1 can be laminated by any method, for example, by the first device 700 or manually.

  The sheet preform 1 has a first surface 1a including the first surface 10a of the label 10 described above and a second surface 1b including the second surface 10b of the label 10 described above. In some cases, the sheet preform 1 is supplied to the cut line forming unit 720 such that the second surface 1b is the upper surface in the vertical direction, and the cut line is formed by the outer peripheral blade of the upper roll 721 of the cut line forming unit 720. It is formed. The number of labels 10 taken out of the sheet preform 1 can be two or more. The number of labels 10 taken out from one sheet preform 1 depends on the relative relationship between the size of the sheet preform 1 and the size of the label 10.

  In the second device 800, one label 10 is selectively fed out from a laminate of a plurality of labels 10 taken out from the sheet base material 1, and the label 10 is attached to the neck 92 of the bottle 90. In some cases, the second device 800 conveys labels, a storage unit 810 that stores a stack of the plurality of labels 10, a label feeding unit 820 that selectively feeds one label 10 from the storage unit 810, and the like. It has a label transport section 830 and a label attaching section 840 for attaching the label 10 to the neck 92 of the bottle 90. The label feeding section 820 can be constructed by cooperation of the pusher 821 and the plurality of rolls 822, 823, 824. The pusher 821 and one or more rolls 822, 823, 824 are driven according to the power supplied from a power source (not shown). In some cases, the label 10 selectively fed from the stack of the plurality of labels 10 is transported to the position where the label 10 is attached to the bottle 90 in the label transport unit 830. A plurality of transport rolls 835 are provided to guide the transport of the fed label 10, and each transport roll 835 can contact the first surface 10 a of the label 10. The first surface 10a of the label 10 is a convex surface, and variation in the degree of warpage is suppressed. Therefore, good contact between the transport roll 835 and the label 10 is ensured. The transport roll 835 can be an active or passive rotating roll. In some cases, the label transport unit 830 has a conveyor belt 831 on which the label 10 to be transported is placed, and the label 10 is transported according to the circulation of the conveyor belt 831. The label 10 can be sandwiched between the conveyor belt 831 and the transport roll 835, and the transport roll 835 can rotate passively. The label attachment 840 can be any means for pushing the label 10 vertically downward and attaching it to the neck 92 of the bottle 90. The label attaching portion 840 is, for example, a pivot plate that pivots so as to push the pair of rod portions 132 of the label 10, and the label 10 supplied on the head 91 of the bottle 90 is pushed downward, and the label 10 The portions P1 to P8, which are the dividing portions for dividing the cut lines 21 and 22, are broken, and the locking portions 11 and 12 of the label 10 pivot in opposite directions, and (according to this pivoting), the locking portions 11 , 12 passes through the head 91 of the bottle 90, the outer peripheral portion 13 of the label 10, and subsequently the locking portions 11, 12 reach the neck 92 of the bottle 90, and the locking portions 11, 12. The locking ends 11 a, 12 a of 12 contact the outer peripheral surface of the neck 92 of the bottle 90.

  In some cases, as can be clearly understood from FIG. 12, the first surface 10a of one of the labels 10 with respect to the adjacent labels 10 in the stacking direction of the labels 10 in the stack of the plurality of labels 10 set in the second device 800. Each label 10 of the laminate is stacked such that the second surface 10b of the other label 10 contacts. In other words, the direction of the warpage of each label 10 of the laminate matches. Thereby, it is possible to more stably and selectively feed out the label 10 from the stack of the labels 10, and to promote more stably transporting the fed out label 10. The possibility that the second device 800 is stopped due to the feeding failure or the feeding failure of the label 10 is reduced, and the improvement of the operation rate of the second device 800 is promoted.

[Example 1]
Fine paper (size: 545 mm × 394 mm, thickness: 170 μm, weight: about 100 g / m 2) was prepared, and surface printing such as a pattern or a character was performed on the surface (first surface) of the fine paper using an offset printing apparatus. .
