Description

  The present invention relates to a heat-shrinkable cylindrical label in which a nonwoven fabric is laminated on a heat-shrinkable film and a method for producing a heat-shrinkable cylindrical label continuous body.

  Generally, food-filled containers filled with coffee, tea, green tea, and the like are heated and sold using a heating thermostat (hot warmer) or the like. Usually, since the filled container taken out from the hot warmer is about 50 to 60 ° C., it feels hot when it is held. In particular, when the container is made of metal, it feels hotter than a synthetic resin molded container or a glass container. In view of such a point, the present applicant has proposed a cylindrical label formed by laminating a nonwoven fabric on the back surface of a heat-shrinkable film as a cylindrical label to be shrink-mounted on a container (Japanese Patent Application No. 2002-230433). ). Such a cylindrical label is used by being heat-shrinked and mounted on the body of the container, and the heat insulation effect of the nonwoven fabric makes it difficult for the user to transmit the heat of the container to the user.

As shown in FIG. 15A, the heat-shrinkable cylindrical label has a back surface and the other side of one end portion 103a of the label base material 103 in which the nonwoven fabric layer 102 is laminated on the back surface of the heat-shrinkable film layer 101. The surface of the end portion 103b is overlapped, and both sides thereof are center-sealed with the adhesive 105, or the both side end portions 103a and 103b of the label base material 103 are overlapped as shown in FIG. A configuration in which the adhesive tape 106 is pasted across the tape is considered (hereinafter, the heat-shrinkable cylindrical label is abbreviated as “cylindrical label” and the heat-shrinkable film layer is abbreviated as “film layer”). Is).
However, since the center seal portion of the former cylindrical label is bonded to the nonwoven fabric layer 102 (the back surface of the one side end portion 103a of the label base material 103) with an adhesive, when this is thermally contracted, While the adhered nonwoven fabric layer 102 is fixed, the film layer 101 at the one side end 103a contracts greatly, so that the film layer shifts as if it slips as shown by the two-dot chain line in FIG. Therefore, one side edge 102a of the nonwoven fabric layer 102 can be seen, resulting in a loss of the appearance of the label. Also, the adhesive strength and strength are not stable depending on the type of nonwoven fabric. On the other hand, in the latter cylindrical label, a tape is used. Therefore, when the center seal is performed, the tension and the feeding timing of the tape 106 and the label base material 103 must be matched well, and the adjustment is complicated.

  Thus, the present invention provides a heat-shrinkable cylinder that can easily form a center seal part in a cylindrical label in which a nonwoven fabric layer is laminated on the back surface of a film layer, and has a beautiful appearance even after heat shrinkage. It is an object of the present invention to provide a method for producing a cylindrical label and a continuous cylindrical label.

The first means of the present invention is a heat-shrinkable cylindrical shape in which both end portions of a label base material on which a nonwoven fabric layer is laminated on the back surface of the heat-shrinkable film layer are overlapped to form a cylinder, and a center seal portion is formed. It is a label, and a film exposed portion not having a nonwoven fabric layer is provided on the back surface of one side end portion of the label base material, and the surface of the film exposed portion and the other side end portion of the label base material are overlapped, A heat-shrinkable cylindrical label attached with a solvent or an adhesive is provided.
In such a cylindrical label, since the center seal portion is formed by superimposing the film exposed portion not having the nonwoven fabric layer on the surface of the other side end portion of the label base material, even after the heat shrinkage, from the edge of the center seal portion. Non-woven fabric can not be seen and beautiful appearance can be secured. Moreover, since the film exposed part and the surface of the other side end of the label substrate (namely, the surface of the film layer) are overlapped, the film surfaces are in contact with each other, and both surfaces are attached using a solvent or an adhesive. And a center seal | sticker part can be formed reliably.

Further, according to the second means of the present invention, the both sides of the label base material on which the nonwoven fabric layer is laminated via the adhesive layer are overlapped on the back surface of the heat-shrinkable film layer to form a cylindrical shape. The one side edge of the nonwoven fabric layer is arranged inside the one side edge of the film layer, and the one side edge of the adhesive layer is more than the one side edge of the nonwoven fabric layer. Is also disposed on the inner side, a film exposed portion is provided on the back surface of one side end portion of the label base material, and the surface of the film exposed portion and the other side end portion of the label base material are overlapped with each other. Alternatively, a heat-shrinkable cylindrical label attached with an adhesive is provided. Here, “inside” refers to the width direction center portion side of the label base material.
Similarly to the above, such a cylindrical label can easily form a center seal portion, and there is no possibility that the nonwoven fabric can be seen from the edge of the center seal portion after heat shrinkage.
Further, among the layers laminated on the back surface of the film layer, one side edge of the nonwoven fabric layer is disposed inside the one side edge of the film layer, and one side edge of the adhesive layer is from one side edge of the nonwoven fabric layer. Is also arranged on the inner side, the substrate thickness of the label substrate increases stepwise from one side edge toward the inside. Therefore, since the outer shape of the cylindrical label inward from the center seal portion is a relatively gentle straight line or curve, a cylindrical label having a beautiful outer peripheral surface shape can be configured. Furthermore, since the one side edge of the adhesive layer is disposed inside the one side edge of the nonwoven fabric layer, the one side edge of the nonwoven fabric layer is a non-adhered portion that is not bonded. Therefore, in the film layer, the portion facing the non-bonded portion is not inhibited from thermal shrinkage by the non-shrinkable nonwoven fabric layer.

Further, according to the third means of the present invention, on the back surface of the heat-shrinkable film layer, both end portions of the label base material laminated in the order of the design print layer and the nonwoven fabric layer are overlapped to form a cylinder, and the center seal portion is A heat-shrinkable cylindrical label formed, wherein one side edge of the design printing layer is arranged on the inner side of one side edge of the film layer, and one side edge of the nonwoven fabric layer is one side edge of the design printing layer Since the film exposed portion is provided on the back surface of the one side end portion of the label base material, the surface of the film exposed portion and the other side end portion of the label base material are superimposed, A heat-shrinkable cylindrical label attached with a solvent or an adhesive is provided.
Similarly to the above, such a cylindrical label can easily form a center seal portion, and after heat shrinkage, a non-woven fabric cannot be seen from the edge of the center seal portion, and a cylindrical label having a beautiful outer peripheral surface shape can be formed. Furthermore, since the one side edge of the design printing layer is arrange | positioned outside the nonwoven fabric layer, a nonwoven fabric layer cannot be seen from the outer peripheral surface of a cylindrical label.

Furthermore, the fourth means of the present invention is a cylinder by overlapping the both ends of the label base material laminated in the order of the design printing layer, the adhesive layer, and the nonwoven fabric layer on the back surface of the heat-shrinkable film layer, A heat-shrinkable cylindrical label formed with a center seal portion, wherein one side edge of the design printing layer is arranged inside the one side edge of the film layer, and one side edge of the adhesive layer is designed printing The label base material is arranged inside the one side edge of the layer and the one side edge of the nonwoven fabric layer is arranged between the one side edge of the design printing layer and the one side edge of the adhesive layer. A heat-shrinkable cylindrical label in which a film exposed portion is provided on the back surface of one side end portion, the film exposed portion and the surface of the other side end portion of the label base material are overlapped and adhered with a solvent or an adhesive I will provide a.
Similarly to the above, such a cylindrical label can easily form a center seal portion, and there is no possibility that the nonwoven fabric can be seen from the edge of the center seal portion after heat shrinkage. Moreover, since at least three layers of the design printing layer, the adhesive layer, and the nonwoven fabric layer are provided on the back surface of the film layer, the thickness of the label base material is increased as compared with the second and third means. However, since each layer is provided so as to be displaced inward, the outer shape of the cylindrical label is a relatively gentle straight line or curve, and a cylindrical label having a beautiful outer peripheral surface shape can be configured. Moreover, since the one side edge part of a nonwoven fabric layer has a non-adhesion part, the part of the film layer which faces this non-adhesion part is not inhibited by heat shrinkage by the nonwoven fabric layer which does not shrink easily.

Further, the fifth means of the present invention is to form a cylinder by overlapping the both ends of the label base material on which the nonwoven fabric layer is laminated via the adhesive layer on the back surface of the heat-shrinkable film layer. The adhesive layer is provided with at least one side edge of the adhesive layer up to one side edge of the nonwoven fabric layer, and the thickness of the adhesive layer is from the inside toward the one side edge of the nonwoven fabric layer. And a film exposed portion is provided on the back surface of the one side end of the label base material by arranging one side edge of the nonwoven fabric layer inside the one side edge of the film layer. Thus, a heat-shrinkable cylindrical label is provided in which the film exposed portion and the surface of the other end portion of the label base material are overlapped and adhered with a solvent or an adhesive.
Similarly to the above, such a cylindrical label can easily form a center seal portion, and there is no possibility that the nonwoven fabric can be seen from the edge of the center seal portion after heat shrinkage. Further, since the layer thickness of the adhesive layer is gradually reduced toward the one side edge of the nonwoven fabric layer, and the one side edge of the nonwoven fabric layer is disposed on the inner side of the one side edge of the film layer, the center seal portion The outer shape of the cylindrical label from the inside toward the inside becomes a relatively gentle straight line or curve as described above, and can form a cylindrical label with a beautiful outer peripheral surface shape. Further, since one side edge of the adhesive layer is provided to at least one side edge of the nonwoven fabric layer, one side edge of the nonwoven fabric layer is integrated with the film layer. Therefore, when the both side edge parts of the label base material are overlapped, there is no fear that one side edge part of the nonwoven fabric layer is rolled, and the center seal part can be formed more easily and reliably.

  As a more preferred embodiment, the center seal portion is formed on the back surface of the heat-shrinkable film layer by superimposing both side ends of the label base material laminated in the order of the design printing layer, the adhesive layer, and the nonwoven fabric layer into a cylindrical shape. The adhesive layer is provided with at least one side edge of the adhesive layer extending to at least one side edge of the nonwoven fabric layer, and the layer thickness gradually decreases from the inside toward the one side edge of the nonwoven fabric layer. And one side edge of the design printing layer is disposed inside the one side edge of the film layer, and one side edge of the nonwoven fabric layer is disposed inside the one side edge of the design printing layer. Thus, a film exposed portion is provided on the back surface of one side end portion of the label base material, and the surface of the film exposed portion and the other side end portion of the label base material are overlapped and adhered with a solvent or an adhesive.

Hereinafter, the present invention will be specifically described with reference to the drawings.
(First embodiment)
In FIG. 1 to FIG. 3, reference numeral 1 denotes a cylindrical shape in which both end portions 5 a and 5 b of a label base material 5 on which a nonwoven fabric layer 3 is laminated on a back surface 2 a of a heat-shrinkable film layer 2 are overlapped. The heat-shrinkable cylindrical label in which the center seal portion 6 is formed by sticking the mating portion with a solvent or an adhesive is shown. The label substrate 5 has a configuration in which at least the layers of the film layer 2, the design printing layer 7, the adhesive layer 8, and the nonwoven fabric layer 3 are laminated in order from the surface side.
Specifically, the label substrate 5 is formed in a rectangular shape having a predetermined width and length, and a design printing layer 7 is provided on the back surface 2a of the heat-shrinkable film layer 2 as shown in FIG. The adhesive layer 8 is provided on the back surface 7 a of the design printing layer 7, and the nonwoven fabric layer 3 is provided on the back surface 8 a of the adhesive layer 8. At one side end portion 5a of the label substrate 5, the design printing layer 7 has one side edge 7b inside the one side edge 2b of the film layer 2 (inner side is the center in the width direction of the label substrate 5). The adhesive layer 8 is arranged so that its one side edge 8b is displaced inside the one side edge 7b of the design printing layer 7, and the non-woven fabric layer. 3, one side edge 3 b is arranged between one side edge 7 b of the design printing layer 7 and one side edge 8 b of the adhesive layer 8. Accordingly, a film exposed portion 9 that does not have the nonwoven fabric layer 3 or the like (the back surface 2a of the film layer 2 is exposed) is provided in a strip shape in the longitudinal direction on the back surface side of the one side end portion 5a of the label base material 5. . In addition, a non-adhesive portion 10 having a predetermined width that is not bonded by the adhesive layer 8 is provided in a strip shape in the longitudinal direction on one side end 3a including the one side edge 3b of the nonwoven fabric layer 3, in other words, the nonwoven fabric. One side end 3a of the layer 3 is a free end. In addition, the other side edge part 5b of the label base material 5 has the other side edge of each layer 2, 7, 8, 3 aligned. Further, as shown in FIG. 2, the other side edge 5c of the label base material 5 extends outward from the center seal portion 6, and the label base material 5 has a portion near the other side edge 5c of the label base material 5. A non-adhesive overlap margin portion 5d is secured to the back surface of the one side end portion 5a.

  The width W1 of the film exposed portion 9 (the interval between the one side edge 2b of the film layer 2 and the one side edge 7b of the design printing layer 7) is not particularly limited as long as it is a width suitable for the center seal. The degree is illustrated. Moreover, the width W2 (the interval between the one side edge 7b of the design print layer 7 and the one side edge 3b) of the design print layer 7 is not particularly limited, but is, for example, about 0.5 to 4 mm, preferably About 1 to 2.5 mm is exemplified. In addition, the width W3 of the non-bonded portion 10 of the nonwoven fabric layer 3 (interval between the one side edge 3b of the nonwoven fabric layer 3 and the one side edge 8b of the adhesive layer 8) is not particularly limited, but is, for example, about 0.5 to 10 mm. Preferably about 1-4 mm is illustrated.

  The heat-shrinkable film layer 2 is formed of a colorless transparent or colored transparent heat-shrinkable film that can be seen through the design printing layer 7, and the material thereof is not particularly limited. For example, polyester-based resins such as polyethylene terephthalate, polypropylene, and the like Examples thereof include films made of olefin resins, styrene resins such as styrene-butadiene copolymers, one kind selected from thermoplastic resins such as cyclic olefin resins and vinyl chloride resins, or mixtures of two or more kinds. Among them, it is preferable to use a polyester resin film having a strong shrinking force in order to pull and shrink the nonwoven fabric layer 3. Moreover, you may be comprised with the laminated | multilayer film which laminated | stacked two or more types of different films. A heat-shrinkable film can be obtained by forming a film by a known production method and stretching the film. The stretching treatment is usually performed at a temperature of about 70 to 110 ° C., and is stretched by 2.0 to 8.0 times, preferably about 3.0 to 7.0 times in the width direction (circumferential direction in the case of a cylindrical label). Is done. Furthermore, in the longitudinal direction (the direction perpendicular to the width direction; the longitudinal direction when a cylindrical label is used), for example, the stretching treatment may be performed at a low magnification of 1.5 times or less. The obtained film becomes a uniaxially stretched film or a biaxially stretched film slightly stretched in a direction orthogonal to the main stretch direction. The thickness of the film layer is preferably about 20 to 60 μm.

The design print layer 7 is provided on the back surface 2a of the film layer 2 with, for example, a predetermined display such as a product name, a solid print such as a design and a white color in a single color or a multicolor print by gravure printing or the like.
The adhesive layer 8 is not particularly limited as long as it is an adhesive capable of adhering the nonwoven fabric layer 3 and the film layer 2, and is an adhesive used in a normal dry lamination method or wet lamination method, for example, an acrylic type Solvent-type adhesives such as polyurethane, vinyl acetate, vinyl chloride, and rubber, or water-soluble adhesives can be used.

As the non-woven fabric layer 3, a non-woven fabric made of polyester, polypropylene, polyethylene, rayon paper, nylon, cupra, or the like in a sheet shape by an adhesion method, a needle punch method, a spun bond method, a melt blow method, pulp fiber, or the like Japanese paper-like non-woven fabric produced by a paper-making method or the like can be used. As the fibers constituting the nonwoven fabric, solid fibers, hollow fibers, or mixed fibers thereof can be used, and it is preferable to use hollow fibers or mixed fibers thereof because they are more excellent in heat insulation. The fiber length is preferably a long-fiber non-woven fabric sheet in terms of strength due to a three-dimensional network structure formed by entanglement of fibers and the handleability of the sheet, and a short-fiber non-woven fabric is preferable in terms of sheet cutting suitability. As the physical properties of the nonwoven fabric sheet, for example, the basis weight is preferably about 10 to 50 g / m ² (preferably 15 to 30 g / m ² ), the thickness is about 80 to 200 μm, and the denier is about 2 to 5 d. Specific examples of such a nonwoven fabric include “Marix” manufactured by Unitika Ltd., “Bonden” manufactured by Toyobo Co., Ltd., “Ecule”, “Unicel” manufactured by Unicel Corporation.
Moreover, as the nonwoven fabric layer 3, a colored nonwoven fabric can also be used. The color of the colored nonwoven fabric is preferably one that is integrated with the design printing layer 7 in design, for example, the same color as the solid printing of the design printing layer 7, or the same color as the outer surface of the container. Illustrated. By using such a colored nonwoven fabric, the upper and lower edges of the nonwoven fabric layer 3 can be made inconspicuous in the cylindrical label 1 in the mounted state. That is, when the cylindrical label 1 is attached to the container, the upper and lower edges of the non-woven fabric layer 3 peek out at the upper and lower edges of the label by the film layer 2 being slightly shrunk in the vertical direction and shifted so as to slide vertically. Although there is a possibility, by using the colored nonwoven fabric, even if the upper and lower edges of the nonwoven fabric layer 3 come out, it can be visually disguised so as to be melted into the design printing layer 7 or the outer surface of the container, and thus the mounting appearance is Not damaged.

The label base material 5 is formed in a cylindrical shape so that the nonwoven fabric layer 3 constitutes the inner peripheral surface of the cylindrical label 1, and as shown in FIG. By superimposing the back surface (that is, the film exposed portion 9) on the surface of the other end portion 5b of the label base material 5, and sticking this superposed surface through the adhesive layer 11 made of a solvent or an adhesive, A center seal portion 6 is configured. The overlapping margin 5d at the other end 5b of the label base 5 is a free end that is not attached to the surface of the one end 5a of the label base 5.
As described above, a solvent or an adhesive can be used for adhering both side ends 5a and 5b of the label base material 5, but in the case of a film capable of solvent adhesion, the thickness of the adhering portion can be reduced, And since it does not inhibit a heat shrink, it is preferable to stick using the solvent which does not contain solid content, such as a resin component. For example, when the label base 5 is a polyester resin, a polystyrene resin, a film in which an amorphous polyolefin resin is laminated on the front and back surfaces, an ether solvent such as tetrahydrofuran, dioxane, dioxolane, methylene chloride, etc. Halogenated hydrocarbon solvents, cycloaliphatic hydrocarbon solvents such as cyclohexane and methylcyclohexane, ketone solvents such as acetone, methyl ethyl ketone and methyl isobutyl ketone, ester solvents such as ethyl acetate and methyl acetate, aliphatic solvents such as hexane Examples thereof include organic solvents such as hydrocarbon solvents, aromatic hydrocarbon solvents such as toluene, and two or more mixed solvents.

The said label base material 5 and the cylindrical label 1 can be manufactured with the following method, for example. Hereinafter, a method for collectively manufacturing an even number of times (for example, four rows) of a label base material continuum from the original film will be described in detail.
As shown in FIGS. 4 (a) and 4 (b), a predetermined width (two rows of label base material continuous bodies 21 and 22 can be obtained by cutting in the longitudinal direction at the base material cutting planned line 20 ′. Assuming that the heat-shrinkable film original fabric having a double width of the label base 5 is one unit, a heat-shrinkable film original fabric 25 in which two units are connected in the width direction is prepared. In other words, the original film 25 is cut in the longitudinal direction at the film cutting planned line 20 at the substantially central portion in the width direction and the substrate cutting planned line 20 ′ of each unit through the respective steps to be described later. Label base material continuum 21, 22, 23, 24 can be obtained.
Out of the back surface of the original film 25, the width W1 corresponding to the film exposed portion 9 from both side edges and the width W1, W1 corresponding to twice the film exposed portion 9 in the center in the width direction of the original film 25. The design printing layer 7 is provided in the longitudinal direction by gravure printing or the like. The design printing layer 7 is printed with the display direction of the product name or the like facing upward in the label base material continuums 21 and 23 in the first row and the third row (odd row), while the second row In the fourth row (even number row) of the label base material continuums 22 and 24, printing is performed in a downward direction. That is, the display of the design print layer 7 is printed in the reverse direction on the pair of label base material continuums 21, 22.

Next, an adhesive layer 8 is provided on the back side of the printed film 25 by applying an adhesive using gravure rolls or the like inside the side edges of each design printing layer 7. Next, the original film 25 is guided to a solvent recovery zone through a conveying roller, and the solvent is blown off to make the adhesive layer 8 semi-dry. Separately, immediately before the nonwoven fabric raw material guided from the nonwoven fabric raw material roll is bonded to the adhesive layer 8, both ends and the center of the nonwoven fabric raw material are slightly wider than the entire width of each adhesive layer 8. A predetermined portion (a portion corresponding to the width W1 and the width W2 shown in FIG. 3) is cut and removed in the longitudinal direction with a cutter, and both side edges of the cut nonwoven fabric are formed on both side edges of the design printing layer 7 and the adhesive layer 8. It arrange | positions so that it may each be located between both edges, a nonwoven fabric is bonded together, and it bonds with the adhesive bond layer 8 with a crimping | compression-bonding roll, and provides the nonwoven fabric layer 3. FIG. Thus, there exists an advantage that the bonding position of a nonwoven fabric is easy to adjust by performing the process of cut | disconnecting a nonwoven fabric original fabric and forming the nonwoven fabric of predetermined width immediately before bonding a nonwoven fabric. More specifically, a nonwoven fabric roll formed in advance with a predetermined width (slightly wider than the adhesive layer 8) is prepared, the nonwoven fabric is fed out from this roll, and both side edges of the design printing layer 7 and both side edges and the adhesive layer It is also possible to bond them so as to be positioned between both side edges, and the present invention can be manufactured by such a process. However, since the nonwoven fabric (and the heat-shrinkable film raw material) at the time of manufacture is long, lateral blurring is likely to occur in the production method in which a nonwoven fabric formed in advance with a predetermined width is guided and bonded. It is necessary to frequently adjust the position in order to guide the film and attach it to an accurate position. In this regard, as described above, the nonwoven fabric raw material is guided to just before the bonding point, and the nonwoven fabric raw material is bonded while being cut in the longitudinal direction between both side edges of the design printing layer 7 and both side edges of the adhesive layer 8. For example, since both side edges of the nonwoven fabric are positioned between the both side edges of the design printing layer 7 and the both side edges of the adhesive layer 8 immediately before the bonding, the position adjustment is also simplified, which is preferable.
In addition, after cut | disconnecting a nonwoven fabric raw material to predetermined width with a cutter as mentioned above, it can replace with the manufacturing method which bonds this nonwoven fabric to a film, and can also carry out at the next process. That is, as shown in FIG. 4 (c), both sides of the design print layer 7 are exposed in order to expose the film exposed portion 9 after the nonwoven fabric original 31 is bonded to the film original 25 provided with the adhesive layer 8. It is also possible to form the nonwoven fabric layer 3 by cutting both side ends and the center portion of the nonwoven fabric raw fabric 31 in the longitudinal direction between the edges and both edges of the adhesive (indicated by arrows in the figure) and removing them. .

  Next, the same four rows of label base material continuous bodies 21,... Are obtained by cutting the whole in the longitudinal direction along the planned film cutting lines 20 and the respective base material cutting scheduled lines 20 ′. In addition, when manufacturing two rows of label base material batches, each process such as printing may be performed using a heat-shrink film raw material having a predetermined width (twice the width of the label base material). In addition, when six or more continuous label base materials are manufactured in a lump, one unit is a heat-shrinkable film original having a predetermined width, and a plurality of these units are formed in the width direction with the planned film cutting line 20 as a boundary. Each process may be performed in the same manner using a film raw material that is continuously connected in units.

And if this label base material continuous body 21 is cut | disconnected by the predetermined direction in the width direction, the one label base material 5 will be obtained, However, Usually, the obtained label base material continuous body 21 is wound up by a roll, It forms in the cylindrical label 1 with a sealing device. Although not specifically shown, this apparatus is cylindrical by applying a solvent or an adhesive along the film exposed portion 9 while pulling out the label base material continuous body 21, and overlapping and sticking the side end portions 5a and 5b. A label continuum is prepared and wound into a roll. In addition, about the label base material continuous bodies 22 and 24 with which the printing direction was reverse, the same cylindrical label continuous body roll wound up by the same printing direction is obtained by winding up.
Next, the cylindrical label continuous body roll is mounted on a shrink labeler. Although the labeler is not particularly illustrated, the cylindrical label 1 is produced by cutting the cylindrical label continuous body from the roll in the width direction at a predetermined length position while being drawn out, and this is inserted into the body of the container. . Then, the inserted container is guided to a shrink zone such as a shrink tunnel, and the cylindrical label 1 is thermally contracted to obtain a labeled container in which the cylindrical label 1 is mounted on the body of the container. .
In addition, although the said manufacturing method has illustrated dry lamination as a lamination | stacking method, what is necessary is just to perform similarly by other lamination methods, such as wet lamination. Further, the adhesive can be applied in a net shape or the like as shown in FIG.

Since the said cylindrical label 1 is provided with the film exposure part 9 in the back surface of the one side edge part 5a of the label base material 5, when this is overlap | superposed with the surface of the other side edge part 5b of the label base material 5, Since the film layers are in contact with each other, the center seal portion 6 can be easily and reliably formed by applying a solvent or an adhesive. Moreover, since the one side edge part 5a of the label base material 5 does not have the nonwoven fabric layer 3, even if it heat-shrinks the cylindrical label 1, the one side edge of a nonwoven fabric does not peek out from the center seal part 6, and is beautiful. Appearance can be secured. Furthermore, in the one side edge part 5a of the label base material 5, each layer 7, 3 in order of the design printing layer 7, the nonwoven fabric layer 3, and the adhesive layer 8 inside the one side edge 2b of the film layer 2. , 8 are provided with their positions shifted, so that the substrate thickness of the label substrate 5 gradually increases, and as shown in FIG. 2, one side edge of the adhesive layer 8 from the center seal portion 6 The outer shape of the label up to 8b is a straight line or a curve with a relatively gentle inclination angle. Therefore, a large level difference does not appear on the surface of the cylindrical label 1, and a beautiful appearance is exhibited even after heat shrinkage. Further, since the one side edge 8b of the adhesive layer 8 is located on the inner side of the one side edge 3b of the nonwoven fabric layer 3, there is no possibility that the adhesive will ooze out from the one side edge 3b of the nonwoven fabric layer 3. When manufacturing the base material 5, after laminating | stacking the nonwoven fabric layer 3, a label base material continuous body can be immediately wound up by a roll. Moreover, since the one side edge 7b of the design print layer 7 is arranged outside the non-woven fabric layer 3, the non-woven fabric layer 3 is not seen through from the outer peripheral surface of the cylindrical label 1, and the periphery is decorated with the design print layer 7. The cylindrical label 1 made can be configured.
Furthermore, since the one side end portion 3a of the nonwoven fabric layer 3 is the non-adhesive portion 10, the heat shrinkability of the film layer 2 facing the portion is not hindered by the nonwoven fabric layer 3 that is difficult to shrink, and therefore, The shrink finish near the center seal portion 6 is good.
Moreover, according to the said manufacturing method, since there are few cutting removal parts of a heat-shrinkable film, a cylindrical label continuous body can be manufactured efficiently. Moreover, since two or more rows (even rows) of label base material continuous bodies in which the film exposed portions 9 are secured and the respective layers 7, 3, and 8 are arranged at appropriate positions can be obtained at a time, the cylindrical label continuous The body can be manufactured.

(Second Embodiment)
The second embodiment relates to a cylindrical label in which an adhesive layer 8 is provided up to one side edge 3 b of the nonwoven fabric layer 3. Hereinafter, parts different from those of the first embodiment will be mainly described, and for the same configuration, terms and drawing numbers are used in the specification and drawings, and the description thereof may be omitted.
As shown in FIG. 5, the label substrate 5 has a configuration in which a design printing layer 7, an adhesive layer 8, and a nonwoven fabric layer 3 are laminated in this order on the back surface 2 a of the heat-shrinkable film layer 2. A film exposed portion 9 is provided on the back surface of the one end portion 5a. At one end 5a of the label substrate 5, the design printing layer 7 has a one side edge 7b arranged closer to the inside than the one side edge 2b of the film layer 2 by a predetermined width W1, and is a non-woven fabric layer. 3, the one side edge 3 b is arranged closer to the inner side than the one side edge 7 b of the design printing layer 7. Furthermore, the adhesive layer 8 is provided up to a position where one side edge 8b of the nonwoven fabric layer 3 protrudes slightly outside the one side edge 3b, and the adhesive layer 8 has a layer thickness from the inside to the nonwoven fabric layer. 3 is provided so as to gradually become thinner toward one side edge 3b. The one end portion 8c of the tapered adhesive layer 8 that gradually inclines downward toward the outside is preferably as the inclination angle is small. For example, the width W4 of the tapered one end portion 8c is 2 to 5 mm. The thing of a grade is illustrated.
And as shown in FIG. 6, the cylindrical label 1 which has the center seal | sticker part 6 is comprised by overlapping the both-ends part 5a, 5b of the label base material 5, and sticking through a solvent etc. Yes.

The label substrate 5 and the cylindrical label 1 of the present embodiment can be manufactured in the same manner as in the first embodiment. Hereinafter, a method for collectively producing two rows of label base material continuum from the film original will be briefly described.
As shown in FIGS. 7A and 7B, a heat-shrinkable film original fabric 27 having a predetermined width is prepared. The design printing layer 7 is provided by gravure printing or the like in the longitudinal direction except for the area corresponding to the film exposed portion 9 from both ends of the back surface of the film original fabric 27. Next, an adhesive layer 8 is provided on the back surface of the printed film original fabric 27 by applying an adhesive using gravure roll plates or the like on the inner side of both side edges of the design printing layer 7 in each row. At this time, both end portions of the adhesive layer 8 are coated so as to gradually become thinner toward the side edge. Next, both end portions of the nonwoven fabric raw material are slightly narrower than the entire width between both side edges of the adhesive layer 8 immediately before the nonwoven fabric raw material guided from the nonwoven fabric raw material roll is bonded to the adhesive layer 8. Is cut and removed in the longitudinal direction with a cutter, placed so that both side edges of the cut non-woven fabric are located slightly inside the both side edges of the adhesive layer 8, and the non-woven fabric is bonded together, and bonded sufficiently with the pressure roll Then, the nonwoven fabric layer 3 is laminated.
In addition, after cut | disconnecting a nonwoven fabric raw fabric to a predetermined width with a cutter as mentioned above, it replaces with the manufacturing method bonded to a film, and it adhere | attaches similarly to the modified example (FIG.4 (c)) of the manufacturing method of the said 1st Embodiment. After laminating the nonwoven fabric original to the film original provided with the agent layer 8, the nonwoven fabric layer is cut and removed in the longitudinal direction at both ends of the nonwoven fabric slightly inside the both side edges of the adhesive layer 8. 3 can also be formed.

Then, the same two rows of label base material continuums 28 and 29 are obtained by cutting the whole in the longitudinal direction along the base material cutting planned line 20 '.
In addition, when manufacturing four or more rows of continuous label base materials in a batch, the heat shrinkable film original fabric 27 having a predetermined width is set as one unit, and the unit is a film in which a plurality of units are continuously connected in the width direction. Each process may be performed in the same manner using the original fabric.

  The obtained label base material continuums 28 and 29 are obtained by superimposing the film exposed portions 9 on the surface of the film layer 3 and sticking them with a solvent or an adhesive to produce a cylindrical label continuum. And then mounted on the body of the container.

Similarly to the first embodiment, the cylindrical label 1 can easily and reliably form the center seal portion 6, and the side edge of the nonwoven fabric cannot be seen from the center seal portion 6 after heat shrinkage. Furthermore, the design printing layer 7 and the nonwoven fabric layer 3 are provided in a position shifted inward, and furthermore, the one side end portion 8c of the adhesive layer 8 is provided in a tapered shape that gradually becomes thinner toward the outside. As shown in FIG. 6, the outer shape of the label from the center seal portion 6 to the one side edge 8b of the adhesive layer 8 is a relatively gentle straight line or curve. Therefore, it has a beautiful appearance with no large steps.
Moreover, since the one side edge part 3a including the one side edge 3b of the nonwoven fabric layer 3 is integrated with the film layer 2 through the adhesive layer 8, the nonwoven fabric layer 3 is formed when the center seal part 6 is formed. The center seal portion 6 can be formed more easily and reliably without the risk of the one side edge 3b from rolling.

  Furthermore, the adhesive layer 8 has one side edge 8b protruding outside the nonwoven fabric layer 3, but the portion of the adhesive layer 8 that protrudes outside the nonwoven fabric layer 3 has a very thin layer thickness. When the label base material continuous body is wound up in a roll shape, it has substantially no adhesive force and there is no possibility of causing interlayer adhesion in the roll. However, the one side edge 8 b of the adhesive layer 8 may be provided so as to coincide with the one side edge 3 b of the nonwoven fabric layer 3.

(Other embodiments)
In addition, the present invention is not limited to the above-described embodiments, and appropriate configurations can be added, substituted, and changed in design within the scope intended by the present invention. Hereinafter, parts different from those of the first and second embodiments will be mainly described. For the same configuration, terms and drawing numbers are used, and description thereof is omitted.
In each of the embodiments described above, the layers provided on the back surface 2a of the film layer 2 are arranged so as to be displaced from each other. For example, one of the two layers among the layers 2, 7, 8, and 3 is used. The side edges may be provided so as to coincide with each other. For example, as shown in FIG. 8, each of the side edges 7 b, 8 b, 3 b of the design printing layer 7, the adhesive layer 8, and the nonwoven fabric layer 3 is provided. The film layers 2 may be aligned and arranged on the inner side of the one side edge 2b.
Moreover, in the cylindrical label 1 of each said embodiment, although the other side edge 5c of the label base material 5 has overlapped with the back surface of the nonwoven fabric layer 3 of the one side edge part 5a of the label base material 5, As shown in FIG. 9, center sealing may be performed so that the other side edge 5 c of the label base material 5 does not overlap the nonwoven fabric layer 3. In the case of such a configuration, the other end edge 5 c of the label substrate 5 is preferably provided in the vicinity of the one side edge 3 b of the nonwoven fabric layer 3. This is because if the distance W5 between the other side edge 5c of the label base material 5 and the one side edge 3b of the nonwoven fabric layer 3 is too wide, the heat insulation effect is reduced, while if the distance W5 is substantially zero, the shrink mounting is performed. This is because the one side end portion 3a (non-adhesive portion 10) of the nonwoven fabric layer 3 that is not thermally contracted sometimes collides with the other side edge 5c of the label base material 5, and this portion may be deformed in a wave shape.
Thus, since the nonwoven fabric layer 3 with a comparatively thick thickness does not overlap the cylindrical label 1 of the structure where the nonwoven fabric layer 3 does not overlap up and down, the cylindrical label 1 with a substantially uniform thickness can be provided as a whole.
Moreover, in each said embodiment, although the design printing layer 7 illustrated what was interposed between the film layer 2 and the nonwoven fabric layer 3, as shown in FIG. 10, for example, the design printing layer 7 is shown. However, the cylindrical label 1 provided on the surface of the film layer 2 may be used. In this case, the design print layer 7 is preferably provided from the one side edge 2b of the film layer 2 to the vicinity of the center seal portion 6 or to a position near the center seal portion 6 as shown in FIG. The manufacturing method of this cylindrical label 1 secures the film exposure part 9 on the back surface of the heat-shrinkable film raw material which carried out the design printing on the surface, applied an adhesive agent, and after that, similarly to 1st Embodiment. Can be manufactured.

Further, in each of the above embodiments, the other side edge 5c of the label base material 5 is provided with the respective layers 2, 7, 8, and 3. For example, as shown in FIG. The other side edges of the respective layers may be provided so as to be symmetrical with respect to the one side end portion 5a. In such a configuration, a step at the other end portion 5b of the label substrate 5 is also present. Since it becomes gradually smaller, the outer shape of the cylindrical label 1 near the center seal portion 6 can be further curved. As a modification of this configuration, the other side edges of two or three layers among the layers 2, 7, 8, and 3 may be provided so as to coincide with each other.
In addition, easy opening means such as perforations may be provided in the longitudinal direction of the cylindrical label 1. For example, as shown in FIG. 11, the easy-opening means 12 such as perforations is preferably provided inside the center seal portion 6 and in the non-bonded portion of the nonwoven fabric layer 3. It may be. Since the nonwoven fabric has almost no tear directionality, it cannot be easily cut even if perforations are formed. However, according to the present invention, since the one side edge 3b of the nonwoven fabric layer 3 is formed inside, the nonwoven fabric layer 3 The perforation 12 can be formed in the non-adhesive portion of the label 1 and the label 1 can be easily cut.

The cylindrical label 1 provided with such easy-opening means can be manufactured by the following method, for example.
As shown in FIG. 12 (a), the design printing layer 7 is gravure-printed in the longitudinal direction except for the area of the width W1 corresponding to the film exposed portion 9 from the both ends of the back surface of the original film 30 having a predetermined width. Etc. Next, an easy-opening means 12 such as a perforation is formed on the original film 30 inside the corresponding region of the film exposed portion 9. Note that the easy-opening means 12 such as perforations can be formed after the label base material continuous body described later is prepared and before the center sealing. Next, as shown in FIG. 4B, an adhesive is applied to the inner side of the perforation 12 (in the case of forming a plurality of perforations 12, the innermost perforation 12). Layer 8 is provided. Next, as shown in FIG. 3C, the nonwoven fabric original fabric is cut with a cutter so that it is slightly wider than the entire width of each adhesive layer 8, and both side edges of the cut nonwoven fabric are on both sides of the design printing layer 7. It arrange | positions so that it may each be located between an edge and the both-sides edge of the adhesive bond layer 8, a nonwoven fabric is bonded together, it bonds together with a crimping | compression-bonding roll, and the nonwoven fabric layer 3 is provided. In addition, after bonding a nonwoven fabric original fabric, the both-ends part of a nonwoven fabric original fabric is cut and removed in a predetermined position, and the nonwoven fabric layer 3 can also be formed. The obtained label base material continuous body is molded into a cylindrical shape and sealed in the same manner as in the first embodiment to obtain a cylindrical label continuous body provided with easy-opening means 12, and FIG. The cylindrical label 1 which concerns on the modification shown can be manufactured.
In addition, an overcoat layer having slipperiness or a mat coat layer for matting may be appropriately provided on the surface of the film layer 2. When the overcoat layer or mat coat layer is applied to the surface of the film layer 2 in this way, the overcoat layer or the like is not provided in the portion where the center seal portion 6 is formed or is provided very thinly. Is preferred.

Moreover, in each said embodiment, although the method which can manufacture the label base material continuum of even number rows, such as 2 rows and 4 rows at a time, is illustrated as a manufacturing method of a label base material continuous, 1 row Or the label base material continuum of the odd number row | line | column of 3 or more rows can also be manufactured at once.
For example, as shown in FIG. 13, the film exposure of one side edge portion of the back surface of the heat-shrinkable film raw material 32 that is slightly wider than the single width of the label base 5 is used as one row of manufacturing methods. The design printing layer 7 is provided in a predetermined region in the longitudinal direction inside a region having a width W1 corresponding to the portion 9. The adhesive layer 8 is provided by applying an adhesive on the back surface of the printed film raw material 32 inside the one side edge of the design printing layer 7. Next, immediately before the non-woven fabric web guided from the non-woven fabric roll is bonded to the adhesive layer 8, the side edges thereof are cut in the longitudinal direction with a cutter so as to be slightly wider than the entire width of the adhesive layer 8. The nonwoven fabric layer 3 is provided by bonding the nonwoven fabric so that one side edge of the cut nonwoven fabric is positioned between one side edge of the design printing layer 7 and one side edge of the adhesive layer 8.
Instead of this, the nonwoven fabric original is bonded between one side edge of the design printing layer 7 and one side edge of the adhesive in order to expose the film exposed portion 9 after the nonwoven fabric raw material is bonded to the film raw material 32. The nonwoven fabric layer 3 can also be formed by cutting and removing the opposite one end in the longitudinal direction, as in the above embodiments.
The obtained label base material continuum is wound into a roll. In addition, as shown in FIG. 13, the unnecessary part X (shown by a two-dot chain line) on both sides of the label base material continuous body, or the unnecessary part of the other side edge of the nonwoven fabric layer 8 from the other side edge of the label base material continuous body. When Y (indicated by a two-dot chain line) appears, the other end of the label base material continuous body may be appropriately cut in the longitudinal direction.

Moreover, what is necessary is just to combine the manufacturing method of the even-numbered row | line | column illustrated in 1st Embodiment with the manufacturing method of the label base material continuous body of the odd-numbered row | line | column of 3 or more rows to the said 1 row manufacturing method.
For example, as a method for producing a three-row label base material continuous body, as shown in FIG. 14, a heat-shrinkable film original fabric 33 having a width approximately three times that of the label base material 5 is prepared. The original film 33 is subjected to the following steps, and is cut in the longitudinal direction by the base material cutting planned line 20 ′ and the film cutting planned line 20 among the three equally divided cutting lines in the width direction, thereby providing three rows of labels. The base material continuous bodies 34, 35, and 36 can be obtained.
Out of the back surface of the original film 33, the width W1 corresponding to the film exposed portion 9 and the width W1, W1 corresponding to twice the film exposed portion 9 centered on the planned film cutting line 20 from the one side edge thereof. Except for this, design print layers 7 'and 7 "are respectively provided. The design print display is printed in the opposite direction on the odd-numbered label base material continuums 34 and 36 and the even-numbered label base material continuum 35. Next, an adhesive is applied to the back side of the printed film original fabric 33 so as to adhere to both side edges of the left design print layer 7 'and inside one side edge of the right design print layer 7 ". Agent layers 8 ′ and 8 ″ are respectively provided. Next, the nonwoven fabric raw material guided from the nonwoven fabric raw material roll is appropriately cut in the longitudinal direction immediately before being bonded to the adhesive layer 8, and both side edges of the left nonwoven fabric 3 ′ are formed. Both the side edges of the left design printed layer 7 'and the left adhesive layer 8' One side edge of the right nonwoven fabric 3 ″ is located between one side edge of the right design printed layer 7 ″ and one side edge of the right adhesive layer 8 ″ so as to be positioned between the edges. The nonwoven fabrics 3 ′ and 3 ″ are bonded to each other. As described above, after the nonwoven fabric raw material is bonded, a procedure of cutting the raw material at an appropriate position can be adopted.
And the same three rows of label base material continuums 34,... Can be obtained by cutting the whole in the longitudinal direction along the planned film cutting line 20 and the base material cutting planned line 20 ′.

  In addition, in the case where two or more (multiple rows) label base material continuums are manufactured, in each of the above embodiments, the design print display is alternately printed in the reverse direction. In this case, the printed design can be printed in the same direction. In this case, the other side edge of the first row of the label base material and the one side edge of the second row are continuous, and the other side edge of the second row and the one side edge of the third row are continuous (four rows). The same applies to the first and subsequent columns, but each column may be performed by the same method as the one column manufacturing method.
