Description

  The present invention relates to a heat-shrinkable cylindrical label to which an adhesive label is attached.

Conventionally, containers with labels in which heat-shrinkable cylindrical labels are mounted around various containers such as beverage containers have been widely distributed. A heat-shrinkable cylindrical label shrinks in the radial direction when heated, and is also called a cylindrical shrink, a shrink tube, or the like.
A heat-shrinkable cylindrical label is usually a tubular body in which a superposed portion is formed by overlapping and bonding one end and the other end of a heat-shrinkable base material and heat shrinkable in the circumferential direction. (Patent Document 1). Such a heat-shrinkable cylindrical label is usually obtained by cutting a long heat-shrinkable tubular label formed of a long belt-like heat-shrinkable base material into a predetermined length. Therefore, the heat-shrinkable cylindrical label elongated body is like a precursor of a heat-shrinkable cylindrical label. And a container with a label is obtained by covering and heating this heat-shrinkable cylindrical label on the outer periphery of the container.

The heat-shrinkable cylindrical label is designed with a design such as a pattern, characters, a description, and a component display. In general, the design is interrupted at the overlapping portion. For this reason, the heat-shrinkable cylindrical label has a problem that an undesigned portion is formed in a band shape in the overlapping portion, and the design integrity in the entire circumferential direction is low. Moreover, since the said superposition | polymerization part is the joint of a heat-shrinkable base material, there also exists a problem that the sense of unity with a heat-shrinkable cylindrical label and a to-be-adhered body is low. That is, a consumer who has picked up a package with a heat-shrinkable cylindrical label attached to the adherend must have a separate label attached to the adherend by the seam (polymerization part). Easily take care of.
In order to eliminate such problems, it is conceivable to apply an adhesive label to the overlapping portion of the heat-shrinkable cylindrical label.
However, when an affixed label is affixed to the overlapping portion of the heat-shrinkable cylindrical label, there is a new problem that wrinkles are generated on the affixed label when the heat-shrinkable cylindrical label is thermally contracted. In particular, when the affixed label is made of a non-heat-shrinkable substrate, or when the substrate has a heat-shrinkable property but the substrate has a different heat-shrinkable rate than the heat-shrinkable cylindrical label The wrinkles are likely to occur.
Patent Document 2 discloses that when forming a heat-shrinkable cylindrical label, the overlapping portion is stopped with a tape, and the heat shrinkage rate approximated to the heat-shrinkable cylindrical label as this tape is disclosed. The use of tape is disclosed. However, Patent Document 2 does not disclose or suggest any problem that wrinkles occur when an affixing label is affixed to the overlapped portion and a solution for the problem.

Hereinafter, the present invention will be specifically described with reference to the drawings.
In this specification, the “front surface” refers to a surface that becomes the outer side of the cylindrical shape when formed into a cylindrical shape (that is, when a heat-shrinkable cylindrical label is formed), and the “back surface” refers to the cylindrical shape. Refers to the inner surface of the shape. Further, “upper” and “lower” as directions terms mean one side and the other side in the axial direction of the heat-shrinkable cylindrical label (in the drawing, the upper side and the lower side). The axis refers to the cylindrical central axis of the heat-shrinkable cylindrical label, and the circumferential direction of the heat-shrinkable cylindrical label refers to the direction around the axis. Furthermore, the description “PPP to QQQ” means “PPP or more and QQQ or less”.
It should be noted that the heat-shrinkable cylindrical label and the thickness and length of each component and the relative ratio of these components in each figure are different from the actual ones.

[First Embodiment]
A heat-shrinkable cylindrical label has the cylindrical body which can heat-shrink in the circumferential direction which formed the heat-shrinkable base material in the cylinder shape, and the sticking label affixed on the said cylindrical body.
Hereinafter, after specifically explaining a cylindrical body and a sticking label, respectively, the heat-shrinkable cylindrical label which has these is demonstrated.

(Tubular body)
In FIG. 1 thru | or FIG. 3, the cylindrical body 1 consists of the heat-shrinkable base material 2, and the heat-shrinkable base material 2 may be provided with the design printing layer as needed. Furthermore, the heat-shrinkable base material 2 may be provided with a layer other than the design print layer. The design print layer and other layers are not shown. Other layers include a protective layer for protecting the substrate, an adhesive layer made of a heat-sensitive adhesive provided on the inner surface of the cylindrical body to fix the heat-shrinkable cylindrical label to the container, a heat-shrinkable cylindrical label In order to improve the slipperiness with respect to the container, a sliding layer provided on the inner surface of the cylindrical body, and the like can be mentioned.
As the heat-shrinkable base material 2, a base material having heat-shrinkability in at least one direction (a circumferential direction when a cylindrical body is used) is used. The heat shrinkability means a property of shrinking when heated to a required temperature (for example, 70 ° C. to 100 ° C.). The heat-shrinkable substrate 2 may slightly heat shrink or slightly heat expand in the other direction (a direction perpendicular to the one direction in the plane of the film).

Examples of the heat-shrinkable substrate 2 include polyester resins such as polyethylene terephthalate and polylactic acid; polyolefin resins such as polypropylene and cyclic olefin resins; polystyrene resins such as polystyrene and styrene-butadiene copolymers; A synthetic resin film made of one kind or a mixture of two or more kinds selected from thermoplastic resins such as vinyl resins can be used. The heat-shrinkable substrate 2 may be composed of a single layer film (single layer film), or may be composed of a laminate in which two or more layers are laminated. When the heat-shrinkable substrate 2 is a laminate, each layer of the laminate can be arbitrarily selected. Examples of the laminate include a laminate in which two or more kinds of synthetic resin films having heat shrinkability are laminated, a laminate in which a transparent gas barrier layer is laminated on a synthetic resin film having heat shrinkability, and heat shrinkability. And a laminate in which a heat insulating layer having heat shrinkability or almost no heat shrinkability is laminated, a laminate in which these layers are arbitrarily laminated, and the like. In addition, as said heat insulation layer, a nonwoven fabric, Japanese paper, a foamed resin sheet, etc. are mentioned. When the heat-shrinkable substrate 2 is a laminate, the material of each layer may be substantially the same or different. When the heat-shrinkable substrate 2 is a single layer film, a film containing a polyester resin (preferably, a polyethylene terephthalate resin) is preferable, and when it is a laminate, at least one layer is a polyester resin. (Preferably, it contains polyethylene terephthalate resin). Further, the heat-shrinkable substrate 2 may further have a self-stretching property on the condition that it has heat-shrinkability in at least one direction.
Although the thickness of the heat-shrinkable base material 2 is not specifically limited, For example, they are 10 micrometers-120 micrometers, Preferably they are 10 micrometers-60 micrometers. In addition, when the heat-shrinkable base material 2 contains a heat insulation layer, the thickness is 50 micrometers-300 micrometers, for example.

The heat shrinkage rate in one direction of the heat-shrinkable substrate 2 is preferably 30% to 90%. The heat-shrinkable substrate 2 may be a film that slightly heat-shrinks or expands in the other direction. The thermal shrinkage rate in the other direction of the substrate is preferably −3 to 15%. Note that the minus of the thermal shrinkage rate means thermal expansion.
However, in the present invention, the heat shrinkage ratio is the length of the test piece before heating (original length) and the length of the base material after the test piece is immersed in warm water of 90 ° C. for 10 seconds (after immersion). Length) and is obtained by substituting into the following equation.
Heat shrinkage rate (%) = [{(original length in one direction or other direction) − (length after immersion in one direction or other direction)} / (original length in one direction or other direction) ] × 100.
According to the affixing structure of the affixing label of the present invention, a heat-shrinkable cylindrical label is heat-shrink heat-mounted on an adherend that requires a relatively high shrinkage (for example, a heat shrinkage rate of 10% or more). In addition, the generation of wrinkles can be effectively suppressed.

The heat-shrinkable base material 2 may be a non-transparent base material such as a milky white base material. However, when the design print layer is provided on the back side, a material having excellent transparency is used.
In the present invention, transparent (colorless transparent or colored transparent) refers to a case where the total light transmittance is 70% or more, preferably 80% or more, and more preferably 90% or more. However, the total light transmittance is measured by a measuring method based on JIS K7105 (plastic optical property test method).

The design print layer is a layer for imparting a desired design to the heat-shrinkable substrate 2, and is a print layer that displays a design such as a product name in one color or multiple colors. The design print layer usually includes a background print layer for making the design stand out, and a design print layer displayed on the background print layer. The design print layer can be formed by a known printing method using a conventionally known ink.
The design print layer can be provided on the front surface or the back surface of the heat-shrinkable substrate 2 or both the front and back surfaces, but is preferably provided on the back surface of the heat-shrinkable substrate 2 from the viewpoint of preventing scratches. But when the heat-shrinkable base material 2 is non-transparent, the said design printing layer is provided in the surface side.
Although the thickness of a design printing layer is not specifically limited, For example, they are 0.1 micrometer-5 micrometers, Preferably, they are 0.2 micrometer-3 micrometers.

The tubular body 1 is configured by forming the heat-shrinkable base material 2 including the design print layer into a tubular shape. Specifically, the heat-shrinkable base material 2 is rounded into a cylindrical shape so that one direction (main heat-shrink direction) of the heat-shrinkable base material 2 is the circumferential direction, and its one end 2a and the other end The cylindrical body 1 is configured by forming the overlapping portion 3 by overlapping the portions 2b.
In the present invention, the overlapping portion 3 is a portion where the one side end portion 2a and the other side end portion 2b overlap. That is, the portion where the heat-shrinkable base material 2 is at least double is the polymerization portion 3. Moreover, the superposition | polymerization part 3 is a strip | belt shape extended in an up-down direction from the upper edge to the lower edge of the cylindrical body 1. FIG.
In the present embodiment, all or part of the overlapping surface of the overlapping portion 3 is bonded via the bonding portion 4. The overlapping portion 3 to which the overlapping surface is bonded is also called a center seal portion. Moreover, in this embodiment, the surface of the other side edge part 2b is piled up on the back surface of the one side edge part 2a of the heat-shrinkable base material 2.
In addition, the said one side edge part 2a is a strip | belt-shaped area | region part extended in an up-down direction in one direction one side among the edge parts of the heat-shrinkable base material 2, and the other side edge part 2b is one direction other side (one side) This is a band-like region extending in the up-down direction on the side opposite to the side.

Although the width 3W of the superposition | polymerization part 3 is not specifically limited, For example, it is 2 mm-20 mm, Preferably, it is 3 mm-10 mm. The width 3W of the overlapping portion 3 is a length between the first side edge 31 and the second side edge 32 of the overlapping portion 3. Here, the first side edge 31 of the overlapping portion 3 refers to one edge (the left edge in FIGS. 1 to 3) among the edges extending in the vertical direction on both sides in the circumferential direction of the overlapping portion 3. The second side edge 32 of the overlapping part 3 refers to the other side edge (the right side edge in FIGS. 1 to 3) among the edges extending in the vertical direction on both sides in the circumferential direction of the overlapping part 3.
In the present embodiment, since the overlapping portion 3 is configured by overlapping the back surface of the one side end portion 2a and the surface of the other side end portion 2b, the first side edge 31 of the overlapping portion 3 is on one side. It corresponds to the edge of the end portion 2a, and the second side edge of the overlapping portion 3 corresponds to the edge of the other side end portion 2b. Hereinafter, the first side edge of the overlapping portion is referred to as “first overlapping side edge”, and the second side edge of the overlapping portion is referred to as “second overlapping side edge”.

The bonding part 4 for bonding the overlapping surfaces is not particularly limited, and examples thereof include known adhesives and solvents. Usually, when the heat-shrinkable base material 2 that can be welded is used, a solvent is used as the bonding portion 4. In the case of using a solvent, the one end portion 2a and the other end portion 2b of the heat-shrinkable base material 2 are directly bonded, so that the bonding portion 4 does not have a thickness. In the drawing, in order to represent the bonding portion 4 in an easily understandable manner, the bonding portion 4 is thickened.
The width of the bonding portion 4 may be the same as or smaller than the width of the overlapping portion 3. When the bonding portion 4 and the overlapping portion 3 have the same width, the entire overlapping surface is bonded. On the other hand, when the width of the bonding portion 4 is smaller than the width of the overlapping portion 3, a portion of the overlapping surface is It is glued. In the illustrated example, the first overlapping side edge 31 to the vicinity of the second overlapping side edge 32 are bonded (part of the overlapping surface of the overlapping portion 3 is bonded).

(Paste label)
In FIG. 4 thru | or FIG. 6, the sticking label 5 consists of a well-known base material. In this embodiment, since the affixing label 5 is affixed from the upper edge to the lower edge of the cylindrical body 1, the affixing label 5 is formed in a strip shape having the same length as the vertical length of the cylindrical body 1. . The sticking label 5 may be provided with a design print layer and other layers as necessary (the design print layer and other layers are not shown).

As the affixing label 5 (base material), a synthetic resin film as exemplified in the heat-shrinkable base material 2; paper; synthetic paper; non-woven fabric; foamed resin sheet; cloth (woven fabric); Examples include a decorative sheet such as a hologram sheet; a glass thin plate; a piece of wood; a laminate of two or more sheets selected from these.
The affixing label 5 may be heat-shrinkable or non-heat-shrinkable (not heat-shrinkable). When the affixed label 5 has heat shrinkability, the heat shrinkage rate is significantly different from the heat shrinkage rate of the heat shrinkable substrate 2 (for example, more than 0.05 times the heat shrinkage rate of the heat shrinkable substrate 2). And less than 0.9 times or more than 1.1 times) or close to the heat shrinkage rate of the heat-shrinkable substrate 2 (for example, 0.9 times the heat shrinkage rate of the heat-shrinkable substrate 2) -1.1 times). When the heat-shrinkable affixing label 5 is used, the affixing label 5 is affixed to the cylindrical body 1 with its heat shrinking direction being parallel to the circumferential direction of the cylindrical body 1.
In the present invention, even if affixed label 5 or a non-heat-shrinkable affixed label 5 having a heat shrinkage rate significantly different from that of heat-shrinkable base material 2 is applied to cylindrical body 1, wrinkle generation is effectively suppressed. Since it can do, it is preferable to use such an adhesive label 5, and it is preferable to use the non-heat-shrinkable adhesive label 5 especially. The base material of the non-heat-shrinkable label 5 includes paper, synthetic paper, cloth (woven fabric), thin-film metal plates, decorative sheets such as leather and hologram sheets, glass thin plates, wood pieces, and heat-shrinkability. A synthetic resin film, a non-woven fabric and a synthetic resin sheet that do not have, and a laminated sheet thereof.
The non-heat shrinkability does not mean that the heat shrink does not occur at all, but includes an error range allowed in the technical field to which the present invention belongs. For example, the non-heat shrinkability includes a heat shrinkage rate of 5% or less, preferably 3% or less.
The affixing label 5 may be non-transparent or transparent. When providing a design print layer, it is preferable to provide a design print layer on the back side of the transparent label 5, and to provide a design print layer on the surface side of the non-transparent label 5. preferable.
Moreover, although the thickness of the sticking label 5 is not specifically limited, It is preferable that it is comparatively thin. For example, the thickness of the sticking label 5 is 10 μm to 200 μm, preferably 10 μm to 60 μm.

The width 5W of the sticking label 5 is larger than the width of the overlapping portion 3. The width 5W of the affixing label 5 is the length between the first side edge 51 and the second side edge 52 of the affixing label 5. Here, the 1st side edge 51 of the said sticking label 5 says the edge of one side (FIG. 4 left edge) among the edges extended in an up-down direction, The 2nd side edge 52 of the said sticking label 5 is , The other edge (the right edge in FIG. 4). Hereinafter, the first side edge of the sticking label is referred to as “first sticking side edge”, and the second side edge of the sticking label is referred to as “second sticking side edge”.
The vertical length of the sticking label 5 is not particularly limited as long as it is the same as or shorter than the vertical length of the cylindrical body 1. Preferably, the vertical length of the sticking label 5 is 1/20 times to 1 time the vertical length of the cylindrical body 1, more preferably 1 time (the same as the vertical length of the cylindrical body 1). ).

The affixing label 5 is affixed to the cylindrical body 1 via an affixing part, as will be described later.
The affixing part is a part for adhering the affixing label 5 to the cylindrical body 1, and is interposed between the affixing label 5 and the cylindrical body 1. The heat-shrinkable cylindrical label of the present invention can be easily manufactured by adhering the adhesive label 5 provided with the adhesive portion in advance to the cylindrical body 1, but the adhesive portion is provided on the cylindrical body 1. Also, it can be obtained by a manufacturing method in which the sticking label 5 is stuck there. However, for the explanation of the heat-shrinkable cylindrical label which is a structure (regardless of the production method), the sticking part may be included in any component of the heat-shrinkable cylindrical label or the cylindrical body 1. For convenience, the sticking part is included in the sticking label 5 and explained.

On the back side of the sticking label 5, there are non-sticking portions 5a, 5b, 5c having a surface where the adhesive is exposed (adhesive surface) and a surface where the adhesive is not substantially exposed (non-adhesive surface). The landing portions 5d and 5e are formed.
The adhering portions 5a, 5b, 5c are formed at three locations in the width direction of the adhering label 5, and the adhering portions 5a, 5b, 5c are vertically moved from the upper edge to the lower edge of the adhering label 5. A strip extending in the direction. Hereinafter, the “first sticking part”, the “second sticking part”, and the “third sticking part” are sequentially described. Two non-sticking parts are formed, and are arranged between the three sticking parts. Similarly, the non-sticking parts 5d and 5e have a strip shape extending in the vertical direction from the upper edge to the lower edge of the sticking label 5. Hereinafter, they are referred to as “first non-sticking portion” and “second non-sticking portion” in order.
The 1st sticking part 5a is formed in the predetermined strip | belt-shaped area | region including all of the upper edge of the sticking label 5, a part of lower edge, and the 1st sticking side edge 51, and the 2nd sticking part 5b is the sticking label 5. The third sticking portion 5c includes a part of the top and bottom edges of the sticking label 5 and the whole of the second sticking side edge 52. It is formed in a predetermined band-like region.
In order to make the sticking portions 5a, 5b, 5c (adhesive surface) of the sticking label 5 easy to understand, innumerable dots are given to them in FIG. 5 for convenience.
The surface on which the pressure-sensitive adhesive is not substantially exposed is (1) no pressure-sensitive adhesive is present on the surface (for example, the pressure-sensitive adhesive is not applied or the pressure-sensitive adhesive is completely hidden by the masking agent). Or (2) Even if an adhesive is present on a small part of the surface, the adhesive label 5 does not have an adhesive force enough to adhere to the cylindrical body 1 (for example, a part where the adhesive is slight) Or the pressure-sensitive adhesive is incompletely concealed with a concealing agent).

The method for forming the adhesive surface is not particularly limited. Since formation of an adhesive surface and a non-adhesive surface is easy, after apply | coating an adhesive to the whole back surface of the sticking label 5, the method of apply | coating a concealing agent except the part used as an adhesive surface is preferable. In the case of this forming method, the portion where the concealing agent is applied becomes a non-adhesive surface.
Specifically, as shown in FIG. 6, the adhesive is applied to the entire back surface of the adhesive label 5, and the adhesive layer A is laminated on the back surface of the adhesive label 5. In this case, the adhesive may be applied to the entire back surface of the affixed label 5 in a solid shape, or the adhesive may be applied to the entire back surface of the affixed label 5 in a mesh shape or innumerable dots.
The pressure-sensitive adhesive is preferably a pressure-sensitive adhesive, but a heat-sensitive adhesive can also be used. The pressure-sensitive adhesive is an adhesive having an adhesive force at normal temperature and maintaining the adhesive force for a long time, and is widely used in conventionally known tack labels. A heat-sensitive adhesive is an adhesive that exhibits an adhesive force when heated and maintains the adhesive force for a long period of time.
Subsequently, a concealing layer B is formed by applying a concealing agent for concealing the adhesive strength of the adhesive to the part of the adhesive layer A excluding the part that becomes the adhesive surface.
The concealing agent is applied in a solid form on the entire portion excluding the portion that becomes the adhesive surface. Examples of the masking agent include ultraviolet curable ink, a coating agent containing silicone, and the like. The thickness of the masking layer B is usually 3 μm to 20 μm. By forming the concealment layer B to be relatively thick, the adhesive force of the adhesive can be reliably concealed.
The portions where the concealing layer B is provided become the non-sticking portions 5d and 5e. Moreover, the back surface of the pressure-sensitive adhesive layer A is exposed at the portion where the concealing layer B is not provided, and becomes the adhering portions 5a, 5b, 5c.

  However, instead of the method of providing the concealing layer B, as shown in FIG. 7, the adhesive layer A is laminated only on the formation area of the sticking part on the back surface of the sticking label 5 and becomes a non-sticking part. The adhesive portions 5a, 5b, 5c and the non-adhesive portions 5d, 5e may be formed by a method in which the adhesive layer A is not provided (that is, the back surface of the adhesive label 5 is left).

(Heat-shrinkable cylindrical label)
In FIG. 8 thru | or FIG. 10, the heat-shrinkable cylindrical label 10 has the said cylindrical body 1 and the affixing label 5 affixed on it. The heat-shrinkable cylindrical label 10 may be affixed with other conventionally known labels in addition to the cylindrical body 1 and the affixed label 5, or a conventionally known configuration such as a perforation line or a notch. It may be.
In addition, in the cross-sectional view of the heat-shrinkable cylindrical label 10, for the sake of convenience, an adhesive label having a structure in which only the pressure-sensitive adhesive layer A is provided without providing a concealing layer (structure in FIG. 7). 5 is illustrated.

The affixing label 5 is affixed to the surface (outer surface) of the cylindrical body 1 including the overlapping portion 3. Specifically, the sticking label 5 is stuck on the outer surface of the cylindrical body 1 across the overlapping portion 3. Accordingly, in the affixing label 5, the first affixing side edge 51 extends from the first overlapping side edge 31 to the first circumferential side, and the second affixing side edge 52 extends from the second overlapping side edge 32 in the circumferential second direction. It extends to the side.
Here, the first circumferential side is one circumferential side of the cylindrical body 1 with respect to the overlapping portion 3, and the second circumferential side is the opposite side in the circumferential direction.
Further, the upper edge and the lower edge of the sticking label 5 coincide with the upper edge and the lower edge of the cylindrical body 1. Therefore, the overlapping portion 3 of the cylindrical body 1 and the vicinity in the circumferential first side and the vicinity in the circumferential second side are covered with the adhesive label 5 from the outside.

The affixing label 5 is bonded to the cylindrical body 1 via the affixing parts 5a, 5b, 5c.
Specifically, as shown in FIG. 10, the affixing label 5 is cylindrical in the entire corresponding region between the first position 71 and the first affixing side edge 51 via the first affixing part 5 a. Bonded to the body 1. The first position 71 is an arbitrary position between the first pasting side edge 51 and the first overlapping side edge 31. In addition, since the said 1st position 71 is between both edges, the 1st sticking side edge 51 and the 1st superposition | polymerization side edge 31 are not included. The width of the adhesion region (the length between the first position 71 and the first sticking side edge 51) is not particularly limited, and can be appropriately set according to the width of the sticking label 5 with respect to the width of the overlapping portion 3. From the viewpoint of sufficiently bonding the sticking label 5 to the cylindrical body 1, the width of the bonding region is preferably 2 mm or more, and more preferably 3 mm or more. Moreover, the upper limit of the width | variety of the said adhesion | attachment area | region is about 1/2 times or less of the circumference of the cylindrical body 1, for example, Preferably, it is 1/4 times or less.

Furthermore, the affixing label 5 is bonded to the cylindrical body 1 in the entire corresponding region between the second position 72 and the second affixing side edge 52 via the third affixing part 5c. The second position 72 is an arbitrary position between the second pasting side edge 52 and the second overlapping side edge 32. In addition, since the said 2nd position 72 is between both edges, the 2nd sticking side edge 52 and the 2nd superposition | polymerization side edge 32 are not included. The width of the adhesion region (the length between the second position 72 and the second sticking side edge 52) is not particularly limited, and can be appropriately set according to the width of the sticking label 5 with respect to the width of the overlapping portion 3. From the viewpoint of sufficiently bonding the sticking label 5 to the cylindrical body 1, the width of the bonding region is preferably 2 mm or more, and more preferably 3 mm or more. Moreover, the upper limit of the width | variety of the said adhesion | attachment area | region is about 1/2 times or less of the circumference of the cylindrical body 1, for example, Preferably, it is 1/4 times or less.
The width of each of the bonding regions is a straight line that is orthogonal to the outer surface of the flat cylindrical body and passes through the first position 71 (or the second position 72), and the outer surface of the flat cylindrical body. It is equivalent to the length between the straight line passing through the first pasting side edge 51 (or the second pasting side edge 52) and the first pasting side edge 51.

  Furthermore, the label 5 is attached to the outer surface of the cylindrical body 1 in the whole or part of the region corresponding to the space between the first overlapping side edge 31 and the second overlapping side edge 32 via the second attaching portion 5b. It is glued to. That is, the affixing label 5 is adhered to the entire or a part of the outer surface of the overlapping part 3 through the second affixing part 5b. The affixing label 5 may be adhered to all of the overlapping portions 3 (in this case, adhered to the entire corresponding region between the first overlapping side edge 31 and the second overlapping side edge 32), Since generation | occurrence | production of soot can be suppressed more, it is preferable to adhere | attach on a part of superposition | polymerization part 3. FIG. In this case, the affixing label 5 is adhered to the entire corresponding region between (1) the first overlapping side edge 31 and the vicinity of the second overlapping side edge 32, and (2) the second overlapping side edge 32. Is bonded in the entire corresponding region between the first overlapping side edge 31 and the first overlapping side edge 31 or (3) does not include the first overlapping side edge 31 and the second overlapping side edge 32 and the first overlapping side Bonding is performed in the entire corresponding region between the position near the edge 31 and the position near the second overlapping side edge 32. Preferably, as shown in FIG. 10, the sticking label 5 is bonded in the region (3) via the second sticking portion 5b. The width of the adhesion region (the length between the position near the first overlapping side edge 31 and the position adjacent to the second overlapping side edge 32) is not particularly limited. For example, the width of the overlapping portion 3 is 0.7. Times to 0.9 times.

In this manner, the sticking label 5 is bonded to each of the three regions extending in a strip shape in the vertical direction of the cylindrical body 1.
Here, adhesion | attachment of the affixing label 5 means that it adhere | attaches with the intensity | strength more than the grade which the affixing label 5 does not squeeze when the heat-shrinkable cylindrical label 10 is heat-shrinked. The adhesive strength of the sticking label 5 is, for example, 2N / 25 mm or more, preferably 3N / 25 mm or more. In the present embodiment, since an adhesive such as a pressure-sensitive adhesive is used to apply the adhesive label 5, the upper limit of the adhesive strength is, for example, 8 N / 25 mm. A pressure-sensitive adhesive is a material that bonds two objects with an adhesive strength that can be peeled off by human power, and the adhesive strength is usually smaller than that using an adhesive or a solvent (therefore polymerization). The adhesive strength of the overlapping surface of the part 3 is usually larger than the adhesive strength of the sticking label 5).
In this specification, the adhesive strength is in accordance with JIS Z 0237. A test piece was attached to the surface of a polyethylene terephthalate film, the test piece was peeled at an angle of 180 degrees, the peeling speed was 300 mm / min, and the temperature was 23 ° C. Measured in a peel test under conditions.

On the other hand, the first non-sticking part 5d of the sticking label 5 faces the area corresponding to the first position 71 and the first overlapping side edge 31, and the sticking label 5 is a cylinder in this area. It is non-adhered to the body 1. The width of the non-bonded region (the length between the first position 71 and the first overlapping side edge 31) is, for example, 1 mm to 5 mm, and preferably 2 mm to 4 mm.
Moreover, the 2nd non-sticking part 5e of the sticking label 5 has faced the area | region corresponding between the said 2nd position 72 and the 2nd superposition | polymerization side edge 32, and the sticking label 5 is a cylinder in this area | region. It is non-adhered to the body 1. The width of the non-bonded region (the length between the second position 72 and the second overlapping side edge 32) is, for example, 1 mm to 5 mm, and preferably 2 mm to 4 mm.
Note that the non-adhesion means that even if it is not attached or is attached, it can be peeled off with an extremely small peeling force. For example, the adhesive strength is 0.5 N / 25 mm or less, preferably 0.3 N / It means that it adheres at 25 mm or less.

Here, in this specification, the expression “region corresponding to between XXX and YYY” means a region between XXX and YYY in principle including XXX and YYY. However, for example, the first position 71 is a boundary point between the region where the adhesive label 5 is adhered to the cylindrical body 1 and the region where the adhesive label 5 is not adhered. And non-adhesive areas will overlap. In the present invention, when such a contradiction in interpretation occurs, the boundary point between the bonded region and the non-bonded region is included in the non-bonded region.
In other words, in other words, the sticking label 5 does not include the first position 71 via the first sticking portion 5a and corresponds to the area between the first position 71 and the first sticking side edge 51. A region that is bonded and does not include the first overlapping side edge 31 and the second overlapping side edge 32 and corresponds between the first overlapping side edge 31 and the second overlapping side edge 32 via the second attaching portion 5b. In addition, it is bonded in a region that does not include the second position 72 and corresponds between the second position 72 and the second sticking side edge 52 via the third sticking portion 5c. A region including a position 71 and a first overlapping side edge 31 and corresponding between the first position 71 and the first overlapping side edge 31, and a second position 72 and a second overlapping side edge 32 and the second position 72 and non-adhesive respectively in the corresponding region between the second overlapping side edge 32 It has been.

The said heat-shrinkable cylindrical label 10 can be manufactured as follows, for example.
First, a long cylindrical body in which the cylindrical bodies 1 are continuously connected is formed by a conventionally known method. Briefly, by superposing one end and the other end of a long heat-shrinkable base material, and bonding the superposed surface using a solvent or the like to form a long overlapped portion A long cylindrical body is formed.
Next, the long sticky label in which the sticking labels having the first to third sticking parts are continuously connected is adhered so as to cover the long superposed part of the long cylindrical body, thereby making the long sticky A heat-shrinkable cylindrical label is produced. Finally, the heat-shrinkable tubular label 10 as shown in FIGS. 8 to 10 can be obtained by cutting the long heat-shrinkable tubular label into a predetermined length. In addition, you may use the long sticky label which does not have a 1st thru | or 3rd sticking part, and apply | coat an adhesive agent (or adhesive) or a solvent to the predetermined position of a long cylindrical body in this case. What is necessary is just to affix the said elongate label after forming a 1st thru | or 3rd adhesion part.

After the heat-shrinkable cylindrical label 10 is externally fitted to various adherends, the tubular body 1 is heat-shrinked by heating, and the heat-shrinkable cylindrical label 10 can be attached to the adherend. The adherend is not particularly limited, and examples thereof include containers filled with desired contents, toys, and daily necessities.
In the heat-shrinkable cylindrical label 10 of the present invention, the affixed label 5 is located in the region corresponding to the first overlapping side 31 to the first position 71 of the overlapping portion 3 and from the second overlapping side edge 32 to the second position 72. Since it is not bonded in the corresponding region, wrinkles are less likely to occur when heat shrinking.
Specifically, when the entire back surface of the sticking label is bonded to the outer surface of the cylindrical body via the sticking portion, the heat-shrinkable cylindrical label is heat-shrinked, and the overlapping portion of the cylindrical body And while the cylindrical body contracts in the first side vicinity and the second side vicinity in the circumferential direction, the affixed label does not substantially or greatly heat shrink, so the first overlapping side edge and the second overlapping side edge The wrinkles (streaks along the first polymerization side edge and the second polymerization side edge) that are clearly visible along the appearance are formed on the label 5. In this regard, according to the present invention, when the cylindrical body 1 is thermally contracted in the circumferential portion first side vicinity and the second side vicinity of the overlapping portion 3 and the overlapping portion 3, as shown in FIG. The affixed label 5 in the bonded area is slightly curved independently of the cylindrical body 1 (not following it). For this reason, the heat-shrinkable cylindrical label 10 of the present invention hardly causes wrinkles that can be visually recognized on the sticking label 5 after heat shrinkage.

Moreover, since the affixing label 5 covers the whole superposition | polymerization part 3 in the said heat-shrinkable cylindrical label 10, the joint of the cylindrical body 1 becomes inconspicuous.
For example, when the heat-shrinkable cylindrical label 10 using a transparent base material having no design print layer as the heat-shrinkable base material 2 is mounted on a container (adhered body) such as a glass bottle, It is possible to give a viewer a sense of unity such that only the sticking label 5 is stuck to the container. In particular, a novel package (a container equipped with a heat-shrinkable cylindrical label) can be provided by applying a novel design to the sticking label 5.
Moreover, in the case of the heat-shrinkable cylindrical label 10 which consists of the heat-shrinkable base material 2 provided with the design printing layer, the superposition | polymerization part 3 (a superposition | polymerization part is a part without a streak design normally). Since the affixing label 5 having a desired design printing layer is affixed, a design can be imparted to the superposed part 3 that is the non-designed part, and the heat-shrinkable cylindrical label 10 has an overall design integrity. Can be granted.

[Second Embodiment]
Next, a second embodiment of the heat-shrinkable cylindrical label of the present invention will be described. However, the same configurations and effects as those of the first embodiment will be omitted (assuming that the description has been omitted), terms and symbols. Is used as is.

In the said 1st Embodiment, although the affixing label 5 is adhere | attached on the outer surface of the cylindrical body 1 in all or one part of the superposition | polymerization part 3 via the 2nd adhering part 5b, it is not limited to this. For example, as shown in FIG. 12, the heat-shrinkable cylindrical label 10 in which the sticking label 5 is not bonded to the overlapping portion 3 may be used. In the heat-shrinkable cylindrical label 10 of the second embodiment, the affixing label 5 is formed between the first position 71 and the first affixing side edge 51 via the first adhering part 5a and the third adhering part 5c. Between the first position 71 and the second position 72, and between the first position 71 and the second position 72. It is non-adhering to the cylindrical body 1 in the whole area | region corresponding to.
The heat-shrinkable cylindrical label 10 of the second embodiment also has the same effect as that of the first embodiment. But the heat-shrinkable cylindrical label 10 of the said 1st Embodiment is preferable from the point which the sticking label 5 is easy to integrate with the cylindrical body 1. FIG.

  In addition, in 2nd Embodiment, although the affixing label 5 is not adhere | attached in all the superposition | polymerization parts 5, for example, the affixing label 5 is adhere | attached in the upper end part and lower end part of the superposition | polymerization part 5, and the upper end part and lower end It may be made non-adhesive in the whole middle part of superposition part 5 except a part (not shown).

[Third Embodiment]
Next, a third embodiment of the heat-shrinkable cylindrical label of the present invention will be described. However, the same configurations and effects as those of the first embodiment will be omitted, and the terms and symbols will be omitted. Is used as is.

In the said 1st Embodiment, although the sticking label 5 is stuck on the outer surface of the cylindrical body 1 across the superposition | polymerization part 3, it is not limited to this. For example, as shown in FIGS. 13 and 14, the pasting label 5 is pasted including the superposition part 3 so that the first pasting side edge 51 extends from the first superposition side edge 31 to the first side in the circumferential direction. The heat-shrinkable cylindrical label 10 may be used. In this case, the 2nd sticking side edge 52 of the sticking label 5 is arrange | positioned in the range which corresponds to the 2nd superposition | polymerization side edge 32, or does not exceed the 2nd superposition | polymerization side edge 32.
And the said sticking label 5 is adhere | attached on the cylindrical body 1 in the whole area | region corresponding between the 1st position 71 and the 1st sticking side edge 51 via the 1st sticking part 5a.
Furthermore, the affixing label 5 has a cylindrical body 1 (polymerization part) in the whole or a part of the region corresponding to the area between the first polymerization side edge 31 and the second polymerization side edge 32 via the second adhesion part 5b. It is adhered to the outer surface of 3). The affixing label 5 may be adhered to the entire corresponding region between the first polymerization side edge 31 and the second polymerization side edge 32 (in this case, from the first polymerization side edge 31 to the second application side). It is preferable that it is bonded to a part of the overlapping portion 3 because the generation of wrinkles can be further suppressed. In this case, the affixing label 5 is adhered to the entire corresponding region between (1) the first overlapping side edge 31 and the position near the second affixing side edge 52, (2) the first overlapping side edge 31. Are adhered in the whole corresponding region between the position adjacent to the second pasting side edge 52, or (3) between the position adjacent to the first overlapping side edge 31 and the position adjacent to the second pasting side edge 52 Bonding is made in all of the corresponding areas in between. Preferably, as illustrated, the affixing label 5 is bonded in the region (2) via the second adhering part 5b.
In addition, it is the same as that of the said embodiment that the sticking label 5 is non-adhering with respect to the cylindrical body 1 in the area | region corresponding between the 1st position 71 and the 1st superposition | polymerization side edge 31. FIG.
The reason why the overlapping portion 3 that is the joint of the cylindrical body 1 is conspicuous in appearance is that the first overlapping side edge 31 is exposed on the outer surface of the cylindrical body 1, and the heat-shrinkable cylindrical shape of the third embodiment. In the label 10, since the affixed label 5 covers the first overlapping side edge 31, the joint of the cylindrical body 1 becomes inconspicuous. Moreover, when heat-shrinkable cylindrical label 10 of 3rd Embodiment is also heat-shrinked, wrinkle generation | occurrence | production of the sticking label 5 can be suppressed. But the heat-shrinkable cylindrical label 10 of 1st Embodiment with which the 2nd superposition | polymerization side edge 32 was also covered with the affixing label 5 is preferable.

The back surface of the upper end part of the sticking label facing the part has an adhesive surface.
15 and 16, the cylindrical body 1 according to the fourth embodiment has at least the upper end portion of the overlapping portion 3 including the upper edge of the overlapping portion 3 cut away. This notched portion is referred to as a notched portion 8. In the example of illustration, the upper end part of the superposition | polymerization part 3 and a part of the circumferential direction 1st side following this are notched. In addition, since the notch part 8 should just contain the upper end part of the superposition | polymerization part 3, only the upper end part of the said superposition | polymerization part 3, the upper end part of the superposition | polymerization part 3, and a part of the 2nd circumferential direction following this, or The upper end part of the superposition | polymerization part 3 and each part of the circumferential direction both sides following this may be notched.
The vertical length of the notch 8 is not particularly limited, and is, for example, 3 mm to 10 mm.

In FIG. 17, the sticking label 5 of 4th Embodiment is formed in the strip | belt shape of the same length as the up-down direction length of the cylindrical body 1 similarly to the said 1st Embodiment, and the 1st, 1st is attached to the back surface. 2 and 3 sticking parts 5a, 5b, and 5c and the 1st and 2nd non-sticking parts 5d and 5e are formed in the shape of a belt in the up-and-down direction.
A sticking part 5f is further provided on the back surface of the upper end part including the upper edge of the sticking label 5 of the present embodiment. When the affixing label 5 is affixed to the cylindrical body 1, the affixing part faces the notch 8 and is exposed to the inside of the cylindrical body 1. Hereinafter, the sticking part facing the notch part 8 is referred to as an upper end sticking part. The upper end sticking portion 5f is an adhesive surface made of an adhesive, as in the first embodiment. In addition, it is preferable that the upper end sticking part 5f is formed with the heat sensitive adhesive. In FIG. 17, innumerable dots are given to all the sticking parts.
The width of the sticking label 5 may be the same as that of the first embodiment, but the width of the upper end portion of the sticking label 5 is formed larger than the width of the notch portion 8. By using such an affixing label 5, the upper end of the affixing label 5 can be affixed to the tubular body 1 while covering the notch 8.

  In FIG. 18 thru | or FIG. 20, the heat-shrinkable cylindrical label 10 of 4th Embodiment is comprised by the said sticking label 5 being affixed on the cylindrical body 1. FIG. The upper end portion of the sticking label 5 is aligned so as to cover the notch portion 8 of the tubular body 1, and the sticking label 5 is stuck across the overlapping portion 3 of the tubular body 1. In addition, the part straddling the superposition | polymerization part 3 among the sticking labels 5 is the 1st position via the 1st sticking part 5a and the 3rd sticking part 5c similarly to the said 1st Embodiment. It adheres to the cylindrical body 1 in the whole area | region corresponding between 71 and the 1st sticking side edge 51, and all the area | regions corresponding between the 2nd position 72 and the 2nd sticking side edge 52. FIG.

  Although the heat-shrinkable cylindrical label 10 of 4th Embodiment can also be manufactured using the elongate cylindrical body 1 and the long sticking label 5 to which the cylindrical body 1 was connected continuously, the notch 8 It is preferable to manufacture separately from the one cylindrical body 1 and the affixing label 5 since it can form easily. Briefly, after producing the cylindrical body 1 shown in FIG. 2, the cylindrical body 1 is folded along the side edge (for example, the first overlapping side edge 31) of the overlapping portion 3 as shown in FIG. Fold flat at X and cut off the upper end Y of the overlapping portion 3 from one side of the flat cylindrical body 1. When the cut cylindrical body 1 is folded again into a flat shape with a crease different from the crease X (so-called refolding), a cylinder in which a notch portion 8 is formed as shown in FIG. A body 1 is obtained. By sticking the sticking label 5 shown in FIG. 17 on the tubular body 1, the heat-shrinkable tubular label 10 of the fourth embodiment can be obtained.

The heat-shrinkable cylindrical label 10 of the fourth embodiment has the same effect as that of the first embodiment.
Furthermore, when the heat-shrinkable cylindrical label 10 of the fourth embodiment is externally fitted to the adherend and then thermally contracted, the heat-shrinkable cylindrical label 10 comes into close contact with the adherend. In the heat-shrinkable cylindrical label 10 of the fourth embodiment, a notch portion 8 is formed at the upper end portion of the cylindrical body 1 and the back surface of the upper end portion of the sticking label 5 facing the notch portion 8 is an adhesive surface (upper end paste). 22, the upper end portion 53 including the upper edge of the sticking label 5 is bonded to the outer surface 9a of the adherend 9 via the upper end sticking portion 5f, as shown in FIG. . When the upper end portion 53 of the sticking label 5 is adhered to the adherend 9, the upper edge 33 of the overlapping portion 3 becomes invisible when viewed from the upper side to the lower side. The superposition part 3 is a thick part where the heat-shrinkable base material 2 is doubled, and when the upper edge 33 is visible, the mounting appearance of the heat-shrinkable cylindrical label 10 is impaired, but according to this embodiment, The upper edge 33 of the overlapping portion 3 can be hidden by the affixing label 5.

  In the present embodiment, the cylindrical body 1 in which the notched portion 8 is formed at the upper end portion of the overlapping portion 3 is used. For example, the notched portion 8 is formed at the lower end portion including the lower edge of the overlapping portion 3. The attached label 5 may be affixed so as to cover the notch 8 using the cylindrical body 1 (not shown). However, since the lower edge of the heat-shrinkable cylindrical label 10 attached to the adherend is usually a difficult-to-see portion, it is preferable that at least the upper end portion of the overlapping portion 3 is cut away.
