Description

[Technical field]

[0001] The present invention relates to a tack label, and more particularly to a thick tack label printed with a three-dimensional design. [Background technology]

[0002] Packaging containers (hereinafter referred to as containers) that are filled primarily with liquids and distributed on the market are known to have a variety of external shapes, and cylindrical containers are commonly used for wine, beer, and other beverages. These containers generally have labels attached to their surfaces, on which the product name and descriptions of the contents are printed.

[0003] Container materials include glass, plastics such as PET, cans, paper, etc. Typically, labels affixed to the surface of a container have a front side printed with attributes of the container, such as the contents, product name, manufacturer / seller name, and letters, marks, etc., such as designs and trademarks (collectively referred to here as "designs"), and are attached to the surface of the container (such as the outside surface of the body) with an adhesive (or bonding material) applied to the back side.

[0004] Labels are applied to the surfaces of containers manually for small quantities, but an automatic labeling device commonly called a "tack labeler" is used to apply labels to large quantities of containers. The tack labeler automatically attaches labels to containers that are continuously transported in by a container transport means, and transports the containers to the next production line or a shipping station. This type of tack labeler uses tack labels coated with an adhesive, and as the tack labels are fed out, they are brought into contact with the side of the body of a moving container and affixed to the body.

[0005] A large number of these tack labels are wound in-line on a long release paper in the shape of a drum, and are loaded in this state into the application station of the tack labeler. Then, each time a container is transported and arrives at the application station, a tack label is sent out one by one.

[0006] 2. Description of the Related Art Tack labels (hereinafter, simply referred to as labels) are known that have a part of the label treated to be "adhesive-resistant" so that the label does not adhere to the surface to which it is attached to a container. For example, labels affixed to bottles of cosmetics and the like have an adhesive applied to the back side and an end that is glued to make them easy to remove when the purchaser disposes of the container. This end is in a peeled-off state, so that the entire label can be easily peeled off by pinching it with the fingers if necessary.

[0007] In addition, in the case of continuous tack label sets to be loaded into a tack labeler, a large number of labels are arranged in-line on release paper, and the leading edge of each label is glued to make it easier to peel off the labels with the tack labeler. Patent documents 1, 2, and 3 disclose prior art related to this type of gluing. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] JP 2013-49215 A [Patent Document 2] Utility Model Registration No. 3079762 [Patent Document 3] JP 2011-59295 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0009] Meanwhile, in the field of labels, development is underway for highly design-oriented tack labels (hereinafter referred to as thick-print tack labels) in which the printing portion of the label is printed in a thick protrusion to form a three-dimensional design on the surface of the label.

[0010] When a thick tack label is applied to the curved surface of a container, if the stress caused by the thickly printed area overcomes its adhesive strength to the container, the label can easily peel off and air bubbles or wrinkles can form.

[0011] After being filled with the contents, the labeled containers are transported to wholesalers, retailers, etc., and are stored in warehouses and other locations under various environments. Even after being sold, the products are not necessarily consumed or used immediately, and may be stored for long periods of time, and the storage locations may be in unexpected environments, such as hot environments, cold environments, high humidity environments, or relatively dry environments. Due to these differences in storage environment, air bubbles may occur in the adhesive-fixed part of the thick tack label, especially when stored for a long period of time in a hot and humid environment. When air bubbles occur in the adhesive-fixed part, they gradually grow larger, causing unnatural lifting and wrinkles, which greatly impairs the three-dimensional design that is the characteristic of thick tack labels.

[0012] The object of the present invention is to solve the above problems and provide a thick tack label that maintains high attachment quality for a long period of time without being affected by the environment in which the container to which the thick tack label is affixed is stored. [Means for solving the problem]

[0013] In order to achieve the above object, a representative configuration that represents the characteristics of the thick tack label according to the present invention is described below. Note that, in order to clarify the configuration of the present invention, reference symbols in the drawings of the embodiments described below are also given, but the present invention is not limited to the members and configurations indicated by these reference symbols.

[0014] The thick tack label according to the present invention is a label to be attached to a label attachment surface (21) of a container (2) having the label attachment surface (21) by a tack labeler, [1] A thick tack label (1) includes a label body (13), the label body (13) includes a base sheet (101) having a design surface on one side that becomes the front side after application to a container, and an adhesive surface on the other side that becomes the back side after application to a container, a printing layer (103) arranged on the design surface side of the base sheet (101) and including a three-dimensional design printed area (103a) that is thickly printed to form a convex portion, and an adhesive layer (104) arranged on the adhesive surface side of the base sheet (101), the adhesive layer (104) has an adhesive-resistant layer (105) on the side of the surface that is applied to the container, and the adhesive-resistant layer (105) forms an adhesive-resistant area (105a) in an area (107) surrounding an area (106) corresponding to the back side of the three-dimensional design printed area (103a).

[0015] [2] The adhesive region (105a) of the adhesive processing layer (105) is characterized in that it is configured with an area of ​​5 to 30% of the area of ​​the three-dimensional design printed region (103a).

[0016] [3] The adhesive stop area (105a) is characterized by being arranged in a halftone dot pattern in an area (107) surrounding an area (106) corresponding to the back surface of the three-dimensional design printing area (103a).

[0017] [4] The adhesive-resistant region (105a) of the adhesive-resistant processing layer (105) is characterized by being made of paint.

[0018] [5] The thickness of the convex portion of the three-dimensional design formed in the three-dimensional design printing area (103a) of the printing layer (103) is 350 μm or less.

[0019] [6] The base sheet (101) is characterized by being a transparent or opaque film.

[0020] [7] The thick tack label (1) is composed of the label body (13) and a release paper (12) that is peeled off and removed during the label application process, and is characterized in that the release paper (12) is peelably laminated to cover the entire area of ​​the label body (13).

[0021] The present invention is not limited to the above-mentioned configurations and the configurations of the embodiments described below, and it goes without saying that various modifications are possible within the scope of the technical concept of the present invention. Effect of the Invention

[0022] According to the thick tack label of the present invention, the adhesive area can be minimized, and air bubbles, wrinkles, and gaps are less likely to occur during the application process, allowing for firm application, thereby providing a thick tack label that can be applied with consistent quality. Furthermore, it is possible to provide a thick tack label that can maintain high application quality for a long period of time without being affected by the environment in which it is stored after application, particularly in a hot and humid environment.

[0023] In addition, the cost of thick tack labels can be reduced by applying paint to the adhesive-resistant layer. Also, instead of painting, a sheet (film) can be applied. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. EXAMPLES

[0026] FIG. 1 is a schematic cross-sectional view for explaining an example of the structure of a thick tack label according to the present invention. In the figure, reference numeral 1 denotes a thick tack label (before application), which is composed of a label body 13 and a release paper 12. FIG. 2 is a plan view for explaining the structural example shown in FIG. 1, and FIG. 3 is a plan view for explaining another structural example of the thick-build tack label according to the present invention.

[0027] The thick tack label 1 of the present invention, as shown in FIG. 1(a), comprises a label body 13, which has a base sheet 101 made of a plastic sheet or thick paper, etc., and a printing layer 103 including a three-dimensional design printed area 103a that is thickly printed to form a convex portion on one side of the base sheet 101, i.e., the design surface side (also called the front or design surface) that will become the surface after application to a container, and an adhesive layer 104 applied to the other side, i.e., the adhesive surface side (also called the back or adhesive surface) that will adhere to the container after application to a container. The material of the base sheet 101 is not particularly limited as long as it is a sheet-like material that has sufficient strength to be stably attached to a container, but a transparent or opaque film is preferable as it can further highlight the three-dimensional design formed in the three-dimensional design printing area 103a.

[0028] The thick tack label 1 is composed of the label body 13 and a release paper 12 that is peeled off and removed during the label application process, and the release paper 12 is releasably laminated to cover the entire area of ​​the label body 13, and the release paper 12 is releasably laminated to cover the entire area of ​​the label body 13 including the adhesive layer 104 and the adhesive fixing area 105a of the adhesive fixing layer 105 described later.

[0029] In the configuration shown in Fig. 1(b), the thick tack label 1 has a laminate layer 102 between a base sheet 101 and a printed layer 103. The laminate layer 102 is made of a material that has good adhesion to both the three-dimensional design printed (thick printed) in the three-dimensional design printed area 103a that constitutes the printed layer 103 and the base sheet 101. If there is good adhesion between the two materials, the laminate layer 102 is not required, and the configuration shown in Fig. 1(a) may be used.

[0030] In addition, although not shown, a laminate layer for protecting the printed surface may be provided on the upper surface of the printed layer 103 including the three-dimensional design printed area 103a.

[0031] On the other surface of the base sheet 101, the adhesive layer 104 on the adhesive surface side, which becomes the back surface after application to the container, is provided with an adhesive-resistant layer 105 on the surface side to be applied to the container. The adhesive layer 105 has an adhesive region 105a formed in a surrounding region 107 (hereinafter also referred to as the "surrounding" or "area corresponding to the periphery of the design") of an area 106 (hereinafter also referred to as the "area corresponding to the design") corresponding to the back side of the three-dimensional design printing area 103a where the three-dimensional design is printed. The adhesive-resistant region 105a of the adhesive-resistant layer 105 has the function of inhibiting the adhesive function of the adhesive layer 104, thereby preventing a specific portion from adhering to the label-attaching surface of the container.

[0032] In this way, an adhesive-resistant layer 105 is provided on the surface of the adhesive layer 104, and an adhesive-resistant area 105a is formed around 107 of an area 106 corresponding to the back surface of the three-dimensional design printed area 103a, thereby providing an area that does not adhere to the container, thereby interposing an air layer between the label and the surface of the container. This air layer distributes the pressure applied to the label during the label application process and prevents localized stress concentration on the label, thereby preventing problems such as wrinkles, stretching, or breakage during application.

[0033] Reference symbol 103a shown in the figure is the three-dimensional design printing area. In FIG. 2, the three-dimensional design is shown as a circle, but the shape of the three-dimensional design is not particularly limited, and a three-dimensional design that matches the contents of the container, such as a complex pattern with unevenness, kanji characters, or numbers, can be adopted. The thick tack label 1 according to the present invention can accommodate a thickness of approximately 350 μm or less at the protruding portions of the three-dimensional design formed in the three-dimensional design printed area 103a of the printed layer 103.

[0034] In the thick tack label 1 according to the present invention, a glue-retaining area 105a that inhibits the adhesiveness of the adhesive layer 104 is formed around 103c of the three-dimensional design printed area 103a, i.e., the outer periphery of the three-dimensional design or the area on the back side of the area corresponding to the frame of the three-dimensional design (area 107 corresponding to the periphery of the design). In Figures 1 and 2, the three-dimensional design printed area 103a and the three-dimensional design are shown by hatching, and the glue-retaining area 105a is shown by light charcoal painting.

[0035] Methods for forming the adhesive area 105a of the adhesive processing layer 105 include applying paint that inhibits the adhesive strength of the adhesive layer 104 or attaching a sheet (film) to the upper surface of the adhesive layer 104, but an appropriate method can be selected depending on the shape of the area 107 corresponding to the periphery of the design and the position and amount of the specific part that is desired to be the adhesive area 105a. For example, if the pattern (shape) of the area where adhesion is not desired is complex, a sheet (film) formed in that pattern (shape) can be attached to the adhesive layer 104 to form the adhesive-retaining area 105a; alternatively, if the pattern of the area where adhesion is not desired is simple, a paint that inhibits the adhesive strength of the adhesive layer 104 can be applied to the area 107 corresponding to the periphery of the design.

[0036] In this way, by adjusting the method of applying paint and the shape of the pattern in the area where adhesion is not desired, i.e., the glue-retaining area 105a, to match the shape of the three-dimensional design printed area 103a and making the area of ​​the glue-retaining area 105a as small as possible, it is possible to stably apply the thick tack label 1 and also make the adhesion condition of the thick tack label 1 less susceptible to the influence of the environment in which the container is stored after application.

[0037] FIG. 4 is a plan view illustrating the design surface side of the thick build tack label according to the present invention, and FIG. 5 is a plan view illustrating the adhesive surface side of the thick build tack label according to the present invention. In the plan view shown in Fig. 4, a three-dimensional design is printed on the design surface side of the base sheet 101 to form a three-dimensional design printed area 103a, and the area along the contour of the three-dimensional design printed area 103a is the periphery 103c of the design. In the configuration example shown in Fig. 5(a), the periphery 103c of the design corresponds to an area 107 corresponding to the periphery of the design on the attachment surface side of the base sheet 101, and is the glued area 105a. The periphery 103c of the design is given a width W toward the outside, and the proportion of the glued area 105a is adjusted by this width W. In Figures 4 and 5, the width W is made thicker for the purpose of explanation, but the width W can be adjusted appropriately depending on the shape and area of ​​the three-dimensional design printed area 103a. For example, if the width W is set to about 0.5 to 3 mm, preferably about 1 to 2 mm, this is preferable as it increases the adhesiveness of the area 106 corresponding to the three-dimensional design printed area 103a, makes it less likely for air bubbles to be trapped, and maintains high adhesion quality.

[0038] Figure 5(b) is a plan view seen from the adhesive surface side in the case where the adhesive area 105a is arranged in a halftone dot pattern around the area 106 corresponding to the back surface of the three-dimensional design printing area 103a, similar to the configuration example shown in Figure 3. In this configuration example, by configuring the glue-fixed area 105a in a halftone dot pattern, the proportion of glue-fixed area 105a is reduced, while the pressing force applied to the adhesive layer 104 in the area 106 corresponding to the design is appropriately released, making it less likely to cause wrinkles, etc., and by minimizing air spaces, the product is less susceptible to the effects of temperature changes, etc.

[0039] By configuring the thick tack label 1 of the present invention as described above, the adhesive effect of the adhesive layer 104 is utilized in the area 106 corresponding to the design on the attachment surface side of the three-dimensional design printed area 103a, and the container and label body 13 are firmly attached, while the area 107 corresponding to the periphery 103c of the design does not adhere firmly to the container, forming an air layer over the entire surface or in a dotted pattern. This allows the pressing force applied during the label attachment process to escape to the air layer in the glue stop area 105a formed in the area 107 corresponding to the periphery of the design, preventing localized stress concentration on the label body 13, particularly the three-dimensional design printed area 103a, and enabling label attachment that maintains stable quality, thereby fully demonstrating the aesthetic effect of the three-dimensional design and imparting a sense of luxury to the product contained in the container. In addition, the overall external light reflection effect of the three-dimensional design and the light transmitted through the container can create an aesthetic appearance effect (engraving effect) for the entire label design.

[0040] In the thick tack label 1 according to the present invention, the adhesive region 105a of the adhesive processing layer 105 is preferably configured to have an area of ​​5 to 30% of the area of ​​the three-dimensional design printed region 103a. If it is 30% or more, the adhesive region 105a becomes large, and for example, when exposed to high temperatures for a long period of time, the amount of expansion increases, making it easy for bubbles to occur and increasing the possibility of destroying the appearance of the three-dimensional design. If it is 5% or less, the pressure applied to the three-dimensional design during the pasting process cannot be released completely, making it easy for wrinkles, lifting, and bubbles to occur. Therefore, the above problem can be solved by setting the area of ​​the adhesive region 105a (in the case of a halftone dot pattern, the total area of ​​the parts that hinder adhesion due to the application of paint or the attachment of a sheet) to 5 to 30%, preferably about 10 to 20%, of the area of ​​the three-dimensional design printed region 103a. For example, in the configuration example shown in FIG. 5(a), the area of ​​the three-dimensional design printing area 103a is set to 2000 mm 2 In this case, the glue stop area 105a formed in the area 107 surrounding the area 106 corresponding to the three-dimensional design printing area 103a is 100 mm 2 ~600mm 2 Adjust the width W so that the In this way, the thick tack label 1 according to the present invention is configured to increase the adhesion area between the thick tack label 1 and the container by minimizing the proportion of the adhesive region 105a, while adjusting the formation position of the adhesive region 105a, the size of the width W, and the dot pattern to prevent the influence of various environments, for example, expansion and deformation of the air layer due to high temperature and humidity. Note that the width W does not need to be the same size around the entire periphery of the region 106 corresponding to the three-dimensional design printing region 103a, and it is possible to adjust the adhesive strength by providing thick and thin parts of the width W depending on the shape of the three-dimensional design.

[0041] The adhesive layer 105 can be made of transparent film, colored transparent film, or light reflective film according to the designer's preference to improve the visual effect of the three-dimensional design.

[0042] In addition, as a verification of storage under high temperature and humidity, when it was stored for 120 hours in an environment of room temperature 40 degrees and humidity 90%, when the entire area 106 corresponding to the three-dimensional design printed area 103a was made into an adhesive-retaining area, the occurrence rate of lifting was 80%, whereas no lifting was observed in the thick build tack label of the present invention. This proves that the thick build tack label of the present invention does not generate air bubbles or lifting even when stored in a storage location under harsh environments of room temperature 40 degrees and humidity 90%.

[0043] FIG. 6 is a schematic diagram illustrating an example of a tack labeler that automatically applies a thick tack label according to the present invention. A plurality of container receiving tables 51 are provided at equal intervals on a rotating table 50, which is a means for transporting containers 2, and containers (without labels) 2 transported by the carry-in conveyor 31 of the container supply mechanism 3 are placed one by one on the container receiving tables 51 by a container loading means (star wheel) 300. The containers 2 first reach the outer guide 93 of the label tucking section 250 on the rotating table 50, which rotates in the direction shown by the thick arrow (counterclockwise in this case). In the label tucking section 250, the tip 14 of the thick tack label body 13, which is peeled off from the release paper 12 of the thick tack label, is peeled off and partially attached (tacked) to the label attachment surface of the container by the pressure between the container 2 and the outer guide 93.

[0044] The container 2 with the tip of the thick tack label tacked moves with the thick tack label body 13 from which the release paper 12 has been completely peeled off not abutting the outer guide 93, and reaches the inner guide 94 that constitutes the label application section (2).

[0045] The container 2 is moved while rolling on the inside guide 94 (3), so that the entire thick tack label body 13 is affixed to the container. The container 2L (container + label) to which the tack label body 13 has been affixed is transferred to the unloading conveyor 41 by the unloading means (star wheel) 400 of the container unloading mechanism 4 as the turntable 50 rotates, and is then handed over to the next process (inspection, shipping station, etc.).

[0046] 7A is an external view of a container to which a thick tack label according to the present invention is attached, and FIG. 7B is an enlarged cross-sectional view taken along line XX of FIG. 7A. A container 2L to which a label body 13 of a thick tack label 1 is attached has a design appearance as if a three-dimensional design was applied to the surface of the container. As shown in FIG. 7(b), the label body 13 to be attached to the container 2 has the three-dimensional design portion firmly attached to the container 2, and an air layer is formed around it. Therefore, even if the product is stored for a long period of time after the label is affixed or in a harsh environment, there will be no air bubbles in the three-dimensional design, causing it to float or distort.In addition, since the surrounding air layer is kept to a minimum, the product is designed to not expand or float to the extent that it would threaten the three-dimensional design.

[0047] In order to attach a label to a container that has a three-dimensional design formed on the surface itself (a container with an uneven surface), a sheet made of heat-shrinkable material is required, and the process of attachment and heat shrinking is required, making the label attachment process expensive. By applying the thick tack label of the present invention to the flat surface of a container, a luxurious, pseudo-three-dimensional design container can be easily obtained, and the thick tack label of the present invention can maintain a high-quality attachment state without being affected by the environment in which the container is stored after application, such as the storage period, storage location, or the temperature and humidity of the storage location.
