[First Embodiment]
FIG. 1 is a plan view of a state in which a heat-shrinkable cylindrical label with a display label is folded flat, FIG. 2 is a view seen from above, and FIG. 3 is a circumferential direction of the cylindrical body FIG. 5 is a cross-sectional view showing the entire display label and a part of a cylindrical body in an enlarged manner. FIG. 4 is a cross-sectional view taken along the layer between the first base material and the cylindrical body in order to facilitate understanding of the portion bonded to the cylindrical body of the first base material. It is sectional drawing cut | disconnected along the interlayer of a 1st base material and a 2nd base material, in order to make intelligible the part adhere | attached with respect to the 1st base material of a 2nd base material.

  1 to 3, the heat-shrinkable cylindrical label 1 with a display label includes a cylindrical body 2 and a display label 3 attached to the cylindrical body 2. The display label 3 includes a first base material 4 and a second base material 5 that are overlaid. The first base material 4 is bonded to the outer surface of the cylindrical body 2 at at least two locations separated in the circumferential direction of the cylindrical body 2, and is not bonded to the outer surface of the cylindrical body 2 in other than that. . Hereinafter, a portion of the first base material 4 that is bonded to the outer surface of the cylindrical body 2 is referred to as “attachment region 41”, and a portion that is not bonded to the outer surface of the cylindrical body 2 is referred to as “non-adhesion region 42”. There is.

The second base material 5 includes at least one of a bonding region 51 that is strongly bonded to the outer surface of the first base material 4 and a non-bonded state and a weakly bonded state to the outer surface of the first base material 4. And a separation region 52 in the state. In the present embodiment, the separation region 52 of the second base material 5 is not adhered to the first base material 4 as a whole. Here, the separation region 52 is a partial region of the second base material 5 and refers to a region that is in a state of separating from the first base material 4 after the heat-shrinkable cylindrical label 1 with a display label is thermally contracted. . The separation region 52 is in a state (non-adhered state) away from the first base material 4 from before the heat shrinkage of the heat-shrinkable cylindrical label 1 with a display label, or before the heat shrinkage. Although it is bonded, the heat-shrinkable tubular label 1 with a display label is in a state (weakly bonded state) away from the first substrate 4 during heat shrinkage.
In FIG. 1, in order to make the adhesion region 41 of the first base material 4 and the bonding region 51 of the second region easy to understand, the area corresponding to the adhesion region 41 is shaded, and countless dots are added to the bonding region 51. It is added.

The cylindrical body 2 is formed in a cylindrical shape with the main heat shrink direction of the heat shrinkable film as the circumferential direction, and heat shrinks in the circumferential direction. Here, in this specification, heat shrinkability refers to a property of shrinking in a predetermined direction at a heat shrink temperature (for example, 70 ° C. to 100 ° C.).
The material of the heat-shrinkable film is not particularly limited as long as the heat-shrinkable film mainly heat-shrinks at least in the horizontal direction (the horizontal direction is a circumferential direction when formed into a cylindrical shape, hereinafter the same). Examples of the heat-shrinkable film include polyester resins such as polyethylene terephthalate and polylactic acid; polyolefin resins such as polypropylene, polyethylene and cyclic olefin resins; polystyrene resins such as polystyrene and styrene-butadiene copolymers; A synthetic resin film made of one or a mixture of two or more selected from thermoplastic resins such as vinyl chloride resins can be used. A laminated film in which two or more kinds of films having heat shrinkability are laminated can also be used. Furthermore, a laminated film in which a functional layer such as a heat insulating layer or a barrier layer is laminated on a film having heat shrinkability can also be used. Examples of the heat insulation layer include a nonwoven fabric and a foamed resin film, and examples of the barrier layer include a metal foil such as an aluminum foil, a metal vapor deposition film, and the like.

  A heat-shrinkable film can be obtained by forming into a film by a well-known manufacturing method and extending | stretching. For example, the heat-shrinkable film made of the laminated film can be obtained by forming a film by a known laminating method and stretching the film. Examples of the laminating method include a coextrusion method, a dry laminating method, a sand laminating method, and a tandem laminating method. The stretching treatment is usually performed by main stretching at a temperature of about 70 to 110 ° C. at a lateral direction of 2.0 to 8.0 times, preferably about 3.0 to 7.0 times. Further, in the longitudinal direction of the film (this longitudinal direction is a direction orthogonal to the lateral direction and is an axial direction when formed into a cylindrical shape, the same applies hereinafter), for example, a low magnification of 1.5 times or less A stretching process may be performed. The obtained film becomes a uniaxially stretched film or a biaxially stretched film stretched in a direction orthogonal to the main stretch direction. Although the thickness of a heat-shrinkable film is not specifically limited, Usually, it is about 30-100 micrometers.

As the heat-shrinkable film, a film that can be thermally shrunk at least in the lateral direction at a heat-shrinking temperature (for example, 70 to 100 ° C.) is used. The heat-shrinkable film may be heat-shrinkable or heat-extensible in the longitudinal direction. For example, the heat shrinkable film preferably has a heat shrinkage rate in the transverse direction of 30% or more when heated to 85 ° C., more preferably 40% or more, and particularly preferably 50% or more. Further, when the heat-shrinkable film can be thermally shrunk or stretched in the machine direction, the heat shrinkage rate in the machine direction when heated to 85 ° C. is −3% to 15%, preferably Is 1% to 10%. In addition, the minus of thermal contraction rate means thermal elongation.
The heat shrinkage ratio when heated to 85 ° C. is the length of the heat shrinkable film before heating (original length) and the length of the film after the film is immersed in warm water of 85 ° C. for 10 seconds. It is the ratio of (length after immersion). The said heat shrinkage rate is calculated | required by substituting into a following formula.
Formula: heat shrinkage rate (%) = [{(original length in the transverse direction (or longitudinal direction) of the film) − (length after immersion in the transverse direction (or longitudinal direction) of the film)} / (of the film Original length in the horizontal direction (or vertical direction)]] × 100.

The heat-shrinkable film may be transparent or opaque, but when design printing is performed on the inner surface of the film, a transparent film is used so that the design can be visually recognized from the outer surface side. The total light transmittance of the transparent film is, for example, 70% or more, preferably 80% or more, and more preferably 90% or more. The said total light transmittance says the value measured by the measuring method based on JISK7361 (the test method of the total light transmittance of a plastic-transparent material).
In addition, for example, design printing (not shown) such as a trade name, a trademark, and a pattern design is applied to the heat-shrinkable film by single color or multicolor printing by gravure printing or the like. The design printing may be performed on the inner surface or the outer surface of the heat-shrinkable film, or on the inner surface and the outer surface, but it is preferable that the design printing is performed on the inner surface of the heat-shrinkable film because it is difficult to be damaged.
The inner surface of the heat-shrinkable film is a surface that becomes the inner surface side of the tubular body 2 when the tubular body 2 is formed using the heat-shrinkable film, and the outer surface of the heat-shrinkable film is a tubular body. The surface which becomes the outer surface side of the shaped body 2 is said.

The cylindrical body 2 is rolled into a cylindrical shape with the transverse direction of the heat-shrinkable film as the circumferential direction, and the inner surface of the second side end portion of the film is overlapped with the outer surface of the first side end portion 21 of the film. It is formed by adhering all or part of the part. This overlapped portion is referred to as a seal portion 23. The first side end portion 21 and the second side end portion 22 are bonded using, for example, a solvent or an adhesive.
Although not particularly illustrated, the cylindrical body 2 may be formed with perforation lines and cut lines for cutting. Moreover, the other arbitrary functional layer (not shown) may be provided in the inner surface or the outer surface of the cylindrical body 2 as needed. Examples of the functional layer include a sliding layer and an overcoat layer that improve sliding properties.

The display label 3 is configured such that the second base material 5 is superimposed on the outer surface of the first base material 4, and a part of the second base material 5 is strongly bonded to the first base material 4.
The first base material 4 and the second base material 5 are each formed from a flexible sheet material. Preferably, the first base material 4 and the second base material 5 are each made of a sheet material that does not substantially heat shrink in the lateral direction, and more preferably, a sheet material that does not substantially heat shrink substantially. . The lateral direction of the base materials 4 and 5 is the circumferential direction of the cylindrical body 2 when the display label 3 is attached to the cylindrical body 2. Hereinafter, the “lateral direction” of the base materials 4 and 5 is referred to as “the circumferential direction of the cylindrical body 2” or “circumferential direction” for convenience. The longitudinal direction of the base materials 4 and 5 is the axial direction of the tubular body 2 when the display label 3 is attached to the tubular body 2. Hereinafter, the “longitudinal direction” of the substrates 4 and 5 is referred to as “axial direction of the cylindrical body 2” or “axial direction” for convenience.
The phrase “not substantially heat shrinkable” means that the heat shrinkable film (tubular body 2) hardly heat shrinks at the heat shrink temperature. When expressed in terms of thermal shrinkage, each of the first base material 4 and the second base material 5 has a thermal shrinkage rate in the circumferential direction of 0 to 5%, preferably 0 in both the circumferential direction and the axial direction. ~ 5%.

The first base material 4 and the second base material 5 are not particularly limited as long as they are flexible sheet materials, and are each independently a paper such as plain paper or high-quality paper; a synthetic paper; a synthetic resin film; A laminated resin film in which a plurality of the same kind of resin layers are laminated; a nonwoven fabric; a foamed resin film; a laminated film in which two or more selected from these are laminated can be used. Examples of the synthetic resin film or the laminated resin film include ester resins such as polyethylene terephthalate and polylactic acid, olefin resins such as polypropylene, styrene resins such as styrene-butadiene copolymers, cyclic olefin resins, and vinyl chloride resins. A stretched film containing a thermoplastic resin such as a resin can be used, and among these, because of excellent mechanical strength, it is preferable to use these biaxially stretched films.
In particular, it is preferable to use a hard sheet material as the second base material 5 and a softer sheet material as the first base material 4. For example, an ester resin film or a laminate film thereof is used as the second base material 5 and an olefin resin film, a styrene resin film or a laminate film thereof is used as the first base material 4 as an example of imparting such hardness. Alternatively, a sheet material having a thickness larger than that of the first substrate 4 may be used as the second substrate 5.
The thickness of the 1st base material 4 and the 2nd base material 5 is not specifically limited, Each is independently 25 micrometers-300 micrometers, for example. For example, when using a synthetic resin film or synthetic paper, the thickness is 25 μm to 120 μm, preferably 30 μm to 100 μm.

  The first base material 4 and the second base material 5 may be transparent or opaque, but are preferably transparent. Synthetic paper is usually milky white and opaque, so when the substrate includes synthetic paper, the substrate is opaque. In addition, since the synthetic resin film is usually transparent, it can be made an opaque substrate by applying opaque printing such as white solid printing or silver solid printing to the synthetic resin film. Moreover, it is good also as an opaque base material by laminating | stacking an opaque layer like a metal vapor deposition film on a synthetic resin film.

The shape of the first base material 4 and the second base material 5 is not particularly limited, and may be a substantially rectangular shape in plan view, as shown in the drawing, and is not particularly illustrated, but is substantially square, substantially circular, or substantially elliptical. Alternatively, a substantially polygonal shape such as a substantially triangular shape or a substantially hexagonal shape may be used. In the present invention, the “substantially” shape means a shape allowed in the technical field to which the present invention belongs. The “substantially” in the shape of a substantially rectangular shape, a substantially square shape, a substantially triangular shape, and a substantially polygonal shape in plan view includes, for example, a shape in which a corner is chamfered, a shape in which a part of a side is slightly inflated or recessed, and a side Includes a slightly curved shape. Further, the “substantially” of the substantially circular shape and the substantially elliptical shape in a plan view includes, for example, a shape in which a part of the circumference is slightly inflated or depressed, and a shape in which a part of the circumference is slightly straight or oblique. It is.
The first substrate 4 and the second substrate 5 may be the same size, or one of them may be larger. The first base material 4 and the second base material 5 in the illustrated example have the same shape and size. Although depending on the circumferential length of the heat-shrinkable cylindrical label 1, the substantially rectangular first base material 4 and second base material 5 are each independently, for example, length × width = 10 mm to 50 mm × 20 mm 100 mm. The first base material 4 and the second base material 5 having the same shape and the same size may be overlapped so that their peripheral edges coincide with each other in a plan view as in the illustrated example. The two base materials 5 may be overlapped so as to be displaced in the axial direction and / or the circumferential direction of the cylindrical body 2 with respect to the first base material 4.

  The first base material 4 is bonded to the outer surface of the cylindrical body 2. The location where the first base material 4 is attached to the tubular body 2 is not particularly limited, and may be any of the central portion in the axial direction, the upper portion, and the lower portion of the tubular body 2. When the 1st base material 4 is affixed on the upper part or lower part of the cylindrical body 2, the upper edge or lower edge of the 1st base material 4 overlaps with the upper edge or lower edge of the cylindrical body 2, or it is The heat-shrinkable cylindrical label 1 with a display label can be manufactured relatively easily, so that the first substrate 4 is separated from the upper edge or the lower edge of the cylindrical body 2. However, it is preferable that it is affixed to the upper part or the lower part of the cylindrical body 2. In the example of illustration, the 1st base material 4 is stuck to the upper part of the cylindrical body 2 that the upper edge separated from the upper edge of the cylindrical body 2 predetermined length (for example, 5-30 mm).

The first base material 4 is not adhered to the cylindrical body 2 in its entirety, and is adhered to the outer surface of the cylindrical body 2 at at least two locations separated in the circumferential direction of the cylindrical body 2. That is, the first base material 4 is affixed to the outer surface of the cylindrical body 2 with at least two independent attachment regions 41 and 41. In the first base material 4, the areas other than the two adhesion areas 41 and 41 are the non-adhesion areas 42 of the first base material 4.
Specifically, the first base material 4 is bonded to the outer surface of the cylindrical body 2 at both sides except for the circumferential central portion, and is not bonded to the cylindrical body 2 at the circumferential central portion. That is, the 1st base material 4 has the adhesion area | region 41 in the circumferential direction both sides, respectively, and has the non-adhesion area | region 42 in the circumferential direction center part. The both side portions are portions extending in a strip shape in the axial direction of the cylindrical body 2.
In the illustrated example, both side portions of the first base material 4 are bonded to the tubular body 2 as a whole from the upper edge to the lower edge of the first base material 4. However, the present invention is not limited to the case where both side portions are entirely bonded from the upper edge to the lower edge of the first base material 4, and the portions slightly apart from the upper edge and / or the lower edge of both side portions are cylindrical. It may be adhered to the body 2. In the illustrated example, both side portions of the first base material 4 are bonded to the tubular body 2 including the side edges of the first base material 4. However, the present invention is not limited to the case where both side portions are bonded to each other including the side edges, and both side portions may be bonded to the cylindrical body 2 in the portion that is inward from the side edges.

  The inner edges 41a and 41a of the two adhesion regions 41 and 41 of the first base material 4 may each be non-linear, but when the heat-shrinkable cylindrical label 1 is heat-shrinked, the first base material 4 The non-adhesive region 42 is easily formed in an arc shape with a small distortion, and thus is formed in a linear shape as shown in the figure, and preferably in a linear shape parallel to the axial direction of the cylindrical body 2. The length between the inner edges 41a, 41a of the two adhesion regions 41, 41 is not particularly limited. However, if the length is too small, the first base material 4 is not adhered when the heat-shrinkable cylindrical label 1 is thermally contracted. If the region 42 does not stand up sufficiently, on the other hand, if it is too large, the non-bonded region 42 may stand up too much and become unstable. From this viewpoint, the length between the inner edges 41a and 41a of the two adhesion regions 41 and 41 is preferably 15 mm to 50 mm. The length between the inner edges 41a and 41a of the two adhesion areas 41 and 41 is the circumferential length between the inner edge 41a of one adhesion area 41 and the inner edge 41a of the other adhesion area 41 opposite thereto. Say. As shown in the figure, when the inner edges 41a and 41a of the two adhesion areas 41 and 41 are respectively straight lines parallel to the axial direction of the cylindrical body 2, the distance between the inner edges 41a and 41a of the two adhesion areas 41 and 41 is shown. Are equal in the axial direction. Although not particularly illustrated, when the length between the inner edges 41a and 41a of the two adhesion regions 41 and 41 is not uniform in the axial direction, the minimum value of the length is preferably 15 mm to 50 mm.

Further, the central portion in the horizontal direction of the first base material 4 is not bonded to the tubular body 2 as a whole from the upper edge to the lower edge. Therefore, the 1st base material 4 has the adhesion area | region 41 on both sides of the non-adhesion area | region 42 made non-adhered to the cylindrical body 2 from the upper edge to the lower edge, respectively.
The adhesion region 41 of the first base material 4 is bonded with a strength higher than the extent that the first base material 4 is not detached from the cylindrical body 2 when the heat-shrinkable cylindrical label 1 is thermally contracted in the circumferential direction. . The bonding strength of the attachment region 41 to the cylindrical body 2 is not particularly limited on the condition that the adhesive is bonded with such strength. For example, the first substrate 4 is peelable from the cylindrical body 2. They may be bonded with an adhesive strength, or may be bonded with an adhesive strength that cannot be peeled off. In this specification, the peelable adhesive strength refers to an adhesive strength that allows the substrate to be peeled off by human power, and that the adhesive strength that cannot be peeled off means that the substrate is peeled off manually. The adhesive strength is such that the base material or the like can break the material when it cannot be peeled off.
In a specific numerical value, for example, the adhesive strength to the extent that the first base material 4 does not come off from the cylindrical body 2 and can be peeled when the heat-shrinkable cylindrical label 1 is thermally contracted is 3 to 50 N / 25 mm. Preferably, it is 5-30N / 25mm. However, according to JIS Z 0237, the said adhesive strength forms a test material (1st base material 4) in width 25mm, adhere | attaches the whole surface of the test material on the other party material (tubular body 2), and peeling angle: It is a value measured in a peel test under the conditions of 90 degrees, peel speed: 300 mm / min, and temperature: 23 ° C.

The method for adhering the first substrate 4 to the cylindrical body 2 is not particularly limited, and a known pressure-sensitive adhesive or adhesive is usually used. In addition, when the 1st base material 4 is a material which can be solvent-bonded to the outer surface of the cylindrical body 2, you may weld the 1st base material 4 to the cylindrical body 2 using a solvent.
In the illustrated example, a pressure-sensitive adhesive layer 91 (or an adhesive layer) is provided on the inner surface of both sides of the first base material 4, and the adhesion region 41 of the first base material 4 is a cylindrical body via the pressure-sensitive adhesive layer 91. 2 is bonded. Thus, when providing the adhesive layer 91 partially in the 1st base material 4, it is preferable to use a hot-melt adhesive as an adhesive.

The second substrate 5 is not entirely bonded to the first substrate 4, but is strongly bonded to the outer surface of the first substrate 4 in a part of the circumferential direction of the second substrate 5. That is, the second base material 5 is strongly bonded to the outer surface of the first base material 4 in at least one joining region 51. The second substrate 5 other than the bonding region 51 is a separation region 52 of the second substrate 5.
The second base material 5 is in a strongly adhered state to the first base material 4 in the joining region 51, and is not adhered to the first base material 4 in the separation region 52.
Here, in the present specification, the strongly bonded state means that the second base material 5 is bonded with a strength higher than that of the first base material 4 when the heat-shrinkable cylindrical label 1 is thermally contracted in the circumferential direction. The non-adhesive state means that it is not adhered. As will be described later, in the weakly bonded state, when the heat-shrinkable cylindrical label 1 is heat-shrinked in the circumferential direction, the second substrate 5 is bonded with such a strength that it is detached from the first substrate 4. Say. Therefore, in this specification, both the strong adhesion state and the weak adhesion state are common in that the second base material 5 is adhered to the first base material 4, but the weak adhesion state is a heat-shrinkable cylinder. The difference is that the second base material 5 is peeled off from the first base material 4 due to a change when the shape label 1 contracts.

The bonding area 51 of the second base material 5 is not particularly limited as long as it is strongly bonded. For example, the second base material 5 can be peeled off from the first base material 4. It may be bonded with strength, or may be bonded with an adhesive strength that cannot be peeled off.
As a specific numerical value, the adhesive strength to such an extent that the second base material 5 does not come off from the first base material 4 and can be peeled when the heat-shrinkable cylindrical label 1 is heat-shrinked is, for example, 3 to 50 N / 25 mm. , Preferably, it is 5-30 N / 25 mm. However, according to JIS Z0237, the said adhesive strength forms a test material (2nd base material 5) in width 25mm, adhere | attaches the whole surface of the test material on the other party material (1st base material 4), and peeling angle : 90 degrees, peel speed: 300 mm / min, temperature: values measured in a peel test under the conditions of 23 ° C.

A method for strongly bonding the bonding region 51 of the second base material 5 to the outer surface of the first base material 4 is not particularly limited, and a known pressure-sensitive adhesive or adhesive is usually used. In addition, when the 2nd base material 5 is a material which can be solvent-bonded to the outer surface of the 1st base material 4, the joining area | region 51 of the 2nd base material 5 is welded to the 1st base material 4 using a solvent. Also good.
In the illustrated example, a pressure-sensitive adhesive layer 92 (or an adhesive layer) is provided on the inner surface of the central portion of the second base material 5, and the bonding region 51 of the second base material 5 is the first base via the pressure-sensitive adhesive layer 92. Bonded to the material 4. Thus, when providing the adhesive layer 92 partially in the 2nd base material 5, it is preferable to use a hot-melt adhesive as an adhesive.

The joining area | region 51 of the 2nd base material 5 will not be specifically limited if it is a part of the circumferential direction of the 2nd base material 5, It can set arbitrarily. Preferably, in the second base material 5, a side end region corresponding to one side in the circumferential direction of the cylindrical body 2 is at least a separation region 52. In other words, in the second base material 5, it is preferable that a side end region corresponding to one side in the circumferential direction of the cylindrical body 2 is not at least the bonding region 51. Further, in the relationship with the first base material 4, it is preferable that the separation region 52 of the second base material 5 includes at least a region corresponding to the adhesion region 41 of the first base material 4. In other words, it is preferable that the region corresponding to the adhesion region 41 of the first substrate 4 in the second substrate 5 is at least the separation region 52.
Specifically, the second base material 5 has a central portion in the circumferential direction that is strongly bonded to the outer surface of the first base material 4, and both side portions in the circumferential direction are not bonded to the first base material 4. That is, the 2nd base material 5 has the joining area | region 51 in the circumferential direction center part, and has the separation area | region 52 in the circumferential direction both sides, respectively. The bonding region 51 is disposed in a region corresponding to a region other than the adhesion region 41 of the first base material 4, while the separation region 52 is an entire region corresponding to the adhesion region 41 of the first base material 4 and non-adhesion. It is disposed in a part of the region 42.
In the illustrated example, the central portion of the second base material 5 is strongly bonded to the first base material 4 as a whole from the upper edge to the lower edge of the second base material 5. However, the present invention is not limited to the case where the entire portion from the upper edge to the lower edge of the circumferential central portion is strongly bonded, and the portion of the central portion that is slightly away from the upper edge and / or the lower edge is the first base material 4. It may be strongly bonded to the outer surface.

Both outer edges 51a, 51a of the joining region 51 of the second base material 5 may be independently non-linear or linear. In the illustrated example, both outer edges 51 a and 51 a of the joining region 51 of the second substrate 5 are formed in a straight line parallel to the axial direction of the cylindrical body 2.
The circumferential length of the joining region 51 is not particularly limited, but if it is too small, the second base material 5 may come off the first base material 4 when the heat-shrinkable cylindrical label 1 is heat-shrinked. On the other hand, if it is too large, the second substrate 5 may bend greatly following the non-adhesive region 42 of the first substrate 4 when the heat-shrinkable cylindrical label 1 is heat-shrinked. From this viewpoint, the circumferential length of the joining region 51 is preferably 3 mm to 10 mm. The circumferential length of the joining region 51 is the circumferential length between the outer edges 51a and 51a of the joining region 51. As shown in the figure, when the two outer edges 51a, 51a of the joining region 51 are linear each parallel to the axial direction of the cylindrical body 2, the circumferential length of the joining region 51 is equal in the axial direction. It is. Although not particularly illustrated, when the circumferential length of the joining region 51 is not uniform in the axial direction, the minimum value of the length is preferably 3 mm to 10 mm.

The second base material 5 is subjected to design printing representing a desired design such as a product name and various guides so that the second base material 5 can be viewed at least from the outer surface side (design printing is not shown). Moreover, the design printing which can be visually recognized at least from the outer surface side may be given to the 1st base material 4 as needed. For example, by adopting various printing methods as described below, the display label 3 can be easily noticeable depending on the design.
(1) At least the outer surface of the opaque second base material 5 is subjected to design printing, and the opaque or transparent first base material 4 is not subjected to design printing. Alternatively, design printing is performed on at least the outer surface of the opaque second base material 5, and design printing is performed on the opaque or transparent first base material 4.
(2) Opaque printing and design printing are performed on the outer surface of the transparent second base material 5, and design printing is not performed on the opaque or transparent first base material 4. Opaque printing and design printing are performed on the outer surface of the transparent second base material 5, and design printing is performed on the opaque or transparent first base material 4.
(3) A hologram layer and a lens layer are formed on the transparent second base material 5 and design printing is performed, and design printing is performed on the opaque or transparent first base material 4.
(4) A moire pattern is formed on at least one of the second base material 5 and the first base material 4. As a method for forming a moire pattern, a method described in JP 2007-30967 A can be used.

The said heat-shrinkable cylindrical label 1 with a display label can be manufactured with the following method, for example.
The heat-shrinkable cylindrical label 1 is usually obtained by cutting a continuous long cylindrical label. The continuous long cylindrical label is like an aggregate of a plurality of heat-shrinkable cylindrical labels 1, and conceptually has a plurality of heat-shrinkable cylindrical labels 1 continuously connected in the axial direction. It can be said. In the present specification, the long length means an elongated rectangular shape in which the length in the length direction is sufficiently longer than the length in the width direction (the width direction is a direction perpendicular to the length direction). . For example, the length in the length direction is 5 times or more, preferably 20 times or more, the length in the width direction.
As shown in FIG. 6A, the first side end portion 21 and the second side end portion 22 of the long heat-shrinkable film 24L are overlapped and bonded to form a seal portion 23. A long cylindrical body 2L having a cylindrical shape made of a heat-shrinkable film is formed.
By attaching the display label 3 to the outer surface of the long cylindrical body 2L at regular intervals in the length direction, a long cylindrical label with a display label as shown in FIG. A continuum 1L is obtained. The heat-shrinkable cylindrical label 1 with the display label is obtained by cutting the continuous cylindrical label 1L with the display label in the width direction (the cutting line is indicated by a one-dot chain line).

The heat-shrinkable cylindrical label 1 with a display label is used by being attached to an adherend such as a container.
For example, as shown in FIG. 7, after the flat heat-shrinkable cylindrical label 1 is folded, it is opened in a cylindrical shape, and is fitted on the container 8 and then heated to the heat-shrink temperature.
When the heat-shrinkable cylindrical label 1 (tubular body 2) is shrunk in the circumferential direction by heating, the heat-shrinkable cylindrical label 1 is attached in close contact with the container 8, as shown in FIGS. Thus, the labeled container 10 in which the separation region 52 of the second base material 5 is lifted from the outer surface of the cylindrical body 2 as the first base material 4 stands is obtained.
At this time, the cylindrical body 2 contracts in the circumferential direction, while the first base material 4 does not contract in the circumferential direction. And as above-mentioned, the 1st base material 4 of the display label 3 is adhere | attached on the cylindrical body 2 in the two adhesion | attachment area | regions 41 and 41 separated in the circumferential direction, and becomes the cylindrical body 2 in the non-adhesion area | region 42. Since it is not bonded, the two adhesion regions 41, 41 of the first base material 4 move so as to approach each other according to the contraction of the cylindrical body 2, and the length between the adhesion regions 41, 41 becomes small, and the non-adhesion region 42 protrudes outward and comes to stand. When the non-bonding region 42 of the first base material 4 stands up in a convex shape such as an arc shape, the second base material 5 strongly bonded to the first base material 4 is pushed outward in the joining region 51, and FIG. As shown in FIG. 9, the separation region 52 of the second substrate 5 protrudes away from the first substrate 4. As in the above-described embodiment, when the joining region 51 is provided at the center in the circumferential direction of the second base material 5, the separation regions 52 and 52 on both sides protrude away from the first base material 4 and are substantially flat. The second base material 5 is parallel to the axial direction of the container 8 and is in a state of being raised from the container 8.
According to the heat-shrinkable cylindrical label 1 with a display label of the present invention, since the display label 3 protrudes greatly from an adherend such as the container 8, it is easily noticeable and has an excellent advertising effect.

The container 8 is not particularly limited, and examples thereof include beverage containers, food containers such as seasonings, cosmetic containers, pharmaceutical containers, and containers that store other articles.
Further, the shape of the container 8 is not particularly limited, and examples thereof include a bottle shape, a substantially cylindrical shape, a substantially elliptical column shape, a substantially quadrangular prism shape such as a substantially quadrangular prism shape, and a substantially saddle shape. The “substantially” of the substantially cylindrical shape and the substantially elliptic cylinder shape includes a shape in which a part of the circumference is slightly inflated or depressed, a shape in which a part of the circumference is slightly straight, and the like. Further, the “substantially” of the substantially polygonal column type such as the substantially quadrangular prism type includes, for example, a shape in which a corner is chamfered, a shape in which a part of a side is slightly inflated or depressed, and a side is slightly curved or inclined. The shape which is doing is included.
Furthermore, the container 8 may have a body part and a cap part that rotates relative to the body part, and has a body part and a cap part that is connected to a part of the body part via a hinge part and opens and closes. But you can. The rotating cap portion may be screwed into the barrel portion with a screw, or may be concavely and convexly fitted into the barrel portion.

About the heat-shrinkable cylindrical label 1 with a display label of this invention, the 1st base material 4 of the display label 3 stands up greatly by carrying out the heat shrink of the periphery to which the display label 3 was affixed greatly, 2nd base The material 5 becomes more conspicuous. For this reason, it is preferable to attach the heat-shrinkable cylindrical label 1 with a display label to a container having a portion with a large diameter difference.
For example, the container 8 shown in FIGS. 8 and 9 is, in order from the bottom, a substantially straight body 81, a shoulder 82 formed integrally with the body 81, and an integral with the shoulder 82. And a cap portion 84 that closes an opening (not shown) opened above the neck portion 83. From the trunk portion 81 to the neck portion 83, the circumference is gradually reduced as it goes upward. The diameter difference between the body 81 and the neck 83 is very large. For example, the circumference of the neck 83 is 0.1 to 0.5 times the circumference of the body 81. The circumferential length of the shoulder portion 82 gradually decreases toward the upper side. For example, the circumferential length of the shoulder portion 82 gradually decreases within a range of more than 0.5 times and less than 1 times the circumferential length of the body portion 81. ing.

When the heat-shrinkable tubular label 1 with a display label of the present invention is attached to the container 8 having such a diameter difference, the periphery to which the display label 3 is attached may be attached so as to correspond to the body portion 81. However, in order to make the first base material 4 stand up, it is preferable to attach the heat-shrinkable cylindrical label 1 with a display label to the container 8 with the periphery where the display label 3 is attached corresponding to the shoulder portion 82. For example, the heat-shrinkable cylindrical label 1 with a display label is placed in a container so that the peripheral cylindrical body 2 to which the display label 3 is attached contracts at a heat shrinkage rate of 10% to 60%, preferably 20% to 50%. 8 is preferable. Thus, when the periphery to which the display label 3 is attached is thermally contracted by 10% to 60%, the degree of protrusion of the non-adhesive region 42 of the first base material 4 is increased accordingly.
In addition, when the heat-shrinkable cylindrical label 1 with a display label is attached from the body portion 81 to the shoulder portion 82, the diameter of the heat-shrinkable tubular label 1 is gradually reduced as the shoulder portion 82 is directed upward. In the portion corresponding to the shoulder portion 82, the heat shrinks gradually as it goes upward. For this reason, when the heat-shrinkable cylindrical label 1 with a display label is attached by heat shrinking in correspondence with the periphery where the display label 3 is attached, as shown in FIG. , 41 becomes smaller toward the upper side in the axial direction of the container 8. That is, the degree of protrusion of the non-adhesion region 42 of the first base material 4 increases as it goes upward in the axial direction of the container 8. However, since the diameter of the shoulder portion 82 is reduced toward the upper side, the second base material 5 is not inclined as much as the shoulder portion 82 of the container 8, and is raised from the container in a state substantially parallel to the axial direction of the container 8. It becomes the state.

  The heat-shrinkable cylindrical label with a display label of the present invention is not limited to the first embodiment, and can be variously changed within the range intended by the present invention. Hereinafter, other embodiments of the present invention will be described. However, configurations different from the embodiments described above will be mainly described, and descriptions of similar configurations will be omitted, and terms and symbols may be used. .

[Second Embodiment]
In the said 1st Embodiment, although the 2nd base material 5 has the joining area | region 51 in the circumferential direction center part, it is not limited to this, It can change variously.
For example, FIG. 11 is an enlarged cross-sectional view of the periphery of the display label of the heat-shrinkable cylindrical label with a display label according to the second embodiment. In FIG. 11, the second base material 5 is strongly bonded to the first base material 4 at one side portion in the circumferential direction. In this case, the bonding region 51 of the second base material 5 may be disposed so as to overlap with one adhesion region 41 of the first base material 4 as illustrated, and is disposed so as not to overlap with the adhesion region 41. May be. When the heat-shrinkable cylindrical label 1 with the display label is attached to the container 8, as shown in FIGS. 12 and 13, the non-adhesive region 42 of the first base material 4 is raised on one side of the second base material 5. A certain separation area 52 protrudes in an inclined manner.

[Third Embodiment]
In the first embodiment, one sheet of the second base material 5 is attached to the first base material 4, but the present invention is not limited to this, and two or more second base materials 5 are attached to the first base material 4. It may be affixed.
For example, FIG. 14 is an enlarged cross-sectional view of the periphery of the display label of the heat-shrinkable cylindrical label with a display label of the third embodiment. In FIG. 14, the second base material 5 is composed of, for example, two base materials 5 </ b> A and 5 </ b> B, and each of the second base materials 5 </ b> A and 5 </ b> B is in a strongly bonded state to the outer surface of the first base material 4. It has the joining area | region 51 and the separation area | region 52 made into the non-adhesion state on the outer surface of the 1st base material 4. FIG. When the heat-shrinkable cylindrical label 1 with the display label is attached to the container 8, the second base materials 5A and 5B project by the standing of the non-adhesive region 42 of the first base material 4 as shown in FIG. It becomes like this. Although depending on the position where the two second base materials 5A and 5B are attached, as shown in FIG. 14, when the two second base materials 5A and 5B are attached side by side in the circumferential direction, The second base materials 5A and 5B project inclining in opposite directions.

[Fourth Embodiment]
In the said 1st Embodiment, although the 1st base material 4 and the 2nd base material 5 are the same shape and the same size, for example, either one may have a larger area than the other.
For example, FIG. 16 shows a labeled container 10 in which a heat-shrinkable cylindrical label 1 with a display label in which the second substrate 5 has a larger area than the first substrate 4 is mounted on the container 8. The second base material 5 has a large area, in particular, as shown in the figure, the second base material 5 is formed so large as to cover the first base material 4, so that the first base bent in a curved shape is formed. The material 4 is hidden and the large second base material 5 is conspicuous, which is preferable.

[Fifth Embodiment]
In the first embodiment, the first base material 4 and the second base material 5 are overlapped so that the peripheral edges thereof coincide with each other. For example, a part or all of the peripheral edge of the first base material 4 and the second base material. You may overlap so that a part or all of the periphery of 5 may not correspond.
For example, in FIG. 17, the second base material 5 is overlapped with the first base material 4 so that the second base material 5 is displaced in the axial direction and the circumferential direction of the cylindrical body 2. It is strongly bonded. In FIG. 17, in order to make the adhesion region 41 of the first base material 4 and the bonding region 51 of the second region easy to understand, a range corresponding to the adhesion region 41 is shaded, and the bonding region 51 is innumerable. Dot is added.

[Sixth Embodiment]
In the said 1st Embodiment, although the 1st base material 4 is adhere | attached on the outer surface of the cylindrical body 2 in two places away in the circumferential direction, it is not limited to this, It is three or more places away in the circumferential direction It may be adhered to the tubular body 2.
For example, FIG. 18 is an enlarged cross-sectional view of the periphery of the display label of the heat-shrinkable cylindrical label with a display label according to the sixth embodiment. In FIG. 18, the 1st base material 4 is adhere | attached on the outer surface of the cylindrical body 2 at three places away in the circumferential direction. That is, the first base material 4 has three adhesion regions 41, 41, 41 that are independent from each other in the circumferential direction, and has a non-adhesion region 42 between the adhesion regions 41. Between the three attachment regions 41, 41, 41, there are two independent non-adhesive regions 42, 42. The second substrate 5 is partly strongly bonded to the outer surface of the first substrate 4. For example, as shown in the drawing, the second base material 5 is strongly bonded to the outer surface of the first base material 4 corresponding to one non-adhesive region 42, and the first base corresponding to the other non-adhesive region 42. It is strongly bonded to the outer surface of the material 4. That is, the second base material 5 has two independent joining regions 51, 51, and the respective joining regions 51, 51 are arranged corresponding to the non-adhesive region 42 of the first base material 4. A separation region 52 is provided between the two bonding regions 51 and 51. When the heat-shrinkable cylindrical label 1 with a display label is attached to the container 8, as shown in FIGS. 19 and 20, the second base material is caused by the standing of the two non-adhesive regions 42, 42 of the first base material 4. 5 comes to protrude. In particular, since the two joining regions 51 of the second base material 5 correspond to the non-adhesive regions 42, 42, the second base material 2 also rises in an arc shape, so that the second base material 5 protrudes more greatly. be able to.

[Seventh Embodiment]
In each said embodiment, although the adhesive layer 91 is provided only in the adhesion area | region 41 of the 1st base material 4, it is not limited to this, For example, as shown in FIG. 21, the inner surface of the 1st base material 4 The pressure-sensitive adhesive layer 91 may be provided over the entire surface, and the masking layer 93 may be provided in a solid form in a range that becomes the non-adhesion region 42 of the first base material 4. In addition, a solid shape means the state provided continuously in the surface direction so as to form one layer. The masking layer 93 is a layer that conceals the adhesive force of the adhesive layer 91. The masking layer 93 can be formed using, for example, an ultraviolet curable ink. By making the thickness of the masking layer 93 relatively large (for example, a thickness of 3 μm to 5 μm), the adhesive force of the pressure-sensitive adhesive layer 91 in the range covered with the masking layer 93 can be substantially concealed. In this case, the area where the solid masking layer 93 is provided becomes the non-adhesive region 42 of the first base material 4, and the exposed surface of the adhesive layer 91 where the masking layer 93 is not provided adheres to the first base material 4. It becomes area 41.
Similarly, instead of the above embodiments, as shown in FIG. 21, an adhesive layer 92 is provided over the entire inner surface of the second base material 5 and masked in a range that becomes the separation region 52 of the second base material 5. The layer 94 may be provided in a solid shape. The masking layer 94 is of a level that can substantially conceal the adhesive force of the adhesive layer 92. In this case, the range in which the masking layer 94 is provided becomes the separation region 52 of the second base material 5 in the non-adhered state, and the exposed surface of the adhesive layer 92 in which the masking layer 94 is not provided is the second base material 5. It becomes the joining area | region 51 of this.

  The display label of the system in which the adhesive force of the adhesive layer 92 is concealed by the masking layer 94 forms the adhesive layer 92 on the entire inner surface of the second base material 5, while the outer surface of the first base material 4 The masking layer 94 is formed in a solid shape in a range where the separation region 52 of the second base material 5 overlaps, and the adhesive layer 92 of the second base material 5 is formed on the masking layer 94 and the masking layer of the first base material 4. It can be obtained by superimposing on a non-formed range.

[Eighth Embodiment]
In each said embodiment, although the separation area | region 52 of the 2nd base material 5 is made into the non-adhesion state to the outer surface of the 1st base material 4, a part or all of the separation area | region 52 is the 1st base material 4. The outer surface may be weakly bonded. The weakly bonded state means that the second base material 5 is bonded with such a strength that the second base material 5 is detached from the first base material 4 when the heat-shrinkable cylindrical label 1 is thermally contracted in the circumferential direction.
In specific numerical values, the adhesive strength in the weakly bonded state is, for example, 0.01 to 2.5 N / 25 mm, preferably 0.01 to 1 N / 25 mm, and more preferably 0.05 to 0. .8N / 25mm. However, according to JIS Z0237, the said adhesive strength forms a test material (2nd base material 5) in width 25mm, adhere | attaches the whole surface of the test material on the other party material (1st base material 4), and peeling angle : 90 degrees, peel speed: 300 mm / min, temperature: values measured in a peel test under the conditions of 23 ° C.

  For example, as shown in FIG. 22, a masking layer 95 having a relatively small thickness is provided in a range in which an adhesive layer 92 is provided over the entire inner surface of the second base material 5 and becomes a separation region 52 of the second base material 5. By providing a solid shape, the separation region 52 can be weakly bonded to the outer surface of the first substrate 4. The masking layer 95 slightly hides the adhesive force of the adhesive layer 92, but allows the adhesive to ooze out. Therefore, the inner surface of the masking layer 95 is weakly bonded to the outer surface of the first substrate 4. The thickness of the masking layer 95 is, for example, 0.5 μm to 3 μm. By reducing the thickness of the masking layer 95, the degree of concealment of the adhesive strength of the pressure-sensitive adhesive layer 92 is reduced (thus increasing the adhesive strength), and by increasing the thickness of the masking layer 95, the degree of concealment of adhesive strength. (Therefore, the adhesive strength is reduced).

  Further, as shown in FIG. 23, the masking layer 96 is innumerable in a range in which the pressure-sensitive adhesive layer 92 is provided over the entire inner surface of the second base material 5 and becomes the separation region 52 of the second base material 5. By providing the stripe region or the stitch shape, the separation region 52 can be weakly adhered to the outer surface of the first substrate 4. That is, by forming the masking layer 96 in a dot shape or the like, the adhesive adheres to the outer surface of the first base material 4 from the gap portion 99 that does not have the masking layer 96 (the inner surface of the adhesive layer 92 is entirely covered). In other words, the separation region 52 in a weakly bonded state can be formed. The thickness of the masking layer 96 may be such that the adhesive force of the adhesive layer 92 can be substantially concealed as in the masking layer 94 of the seventh embodiment, or the adhesive force of the adhesive layer 92 is slightly reduced. It may be a degree of hiding.

  Further, as shown in FIG. 24, the separation region 52 is a region 521 that is not bonded to the first base material 4, a region 522 that is weakly bonded to the first base material 4, You may have. In the illustrated example, the region 521 that is not adhered to the first base material 4 is formed by forming the masking layer 94 of the seventh embodiment on the pressure-sensitive adhesive layer 92. On the other hand, the region 522 that is in a weakly bonded state is configured by forming a masking layer 96 on the pressure-sensitive adhesive layer 92 in a dot shape or the like. As described above, when a part of the separation region 52 is weakly bonded to the outer surface of the first base material 4 and a part of the separation region 52 is not bonded to the outer surface of the first base material 4, The weakly bonded region 522 can be set at any location on the second substrate 5. In order to make it difficult for the separation region 52 to be rolled when the heat-shrinkable cylindrical label with a display label is transported or attached, the weakly bonded region 522 is provided corresponding to the side portion of the second substrate 5. Preferably it is.

In the case where the masking layer 96 of the present embodiment is formed in a dot shape or a stitch shape, the adhesive exposed from the gap portion 99 that does not have the masking layer 96 adheres to the outer surface of the first substrate 4 as described above. By doing so, the separation region 52 is in a weakly bonded state, but the adhesive strength of the separation region 52 can be adjusted by appropriately setting the area of the gap portion 99. For example, FIG. 23 shows a case where the area of the gap portion 99 is made relatively small by forming the masking layer 96 such as dots in a relatively dense manner, and FIG. 24 compares the masking layer 96 such as dots. This represents a case where the area of the gap portion 99 is made relatively large by forming a rough surface. Further, when the area of the gap portion 99 is set to be relatively large, the masking layer 96 is formed like one hole so that only one gap portion 99 is formed in one separation region 52. May be.
Moreover, in this embodiment, you may perform an easy peeling process on the outer surface of the 1st base material 4 which faces the separation area | region 52 of the said 2nd base material 5 as needed (not shown). Examples of the easy peeling treatment include forming a coating film containing a silicone resin on the outer surface of the first base material 4 facing the separation region 52.

  As in this embodiment, the heat-shrinkable cylindrical label 1 with a display label in which a part or all of the separation region 52 of the second base material 5 is in a weakly bonded state to the outer surface of the first base material 4 The separation area 52 of the second base material 5 is difficult to roll during the conveyance or attachment to the adherend, and the handleability is excellent. Note that the separation region 52 does not curl at the time of conveyance or attachment to the adherend, but when the heat-shrinkable cylindrical label is thermally contracted, the separation region 52 is not removed from the first base material 4 as described above. To float away from.

[Ninth Embodiment]
In each said embodiment, although parts other than the part (attachment area | region) adhere | attached on the outer surface of the cylindrical body 2 among the 1st base materials 4 are not adhere | attached on the outer surface of the cylindrical body 2 (non-adhesion area | region and However, portions of the first base material 4 other than the adhesion region may be weakly bonded to the cylindrical body 2 (not shown). In this case, the weak adhesion is such that the heat shrinkable cylindrical label 1 is heat-shrinked in the circumferential direction, and the portion other than the adhesion region of the first base material 4 is bonded with such a strength as to be detached from the cylindrical body 2. That means. As specific numerical values, the adhesive strength of weak adhesion in the portion other than the adhesion region is 0.01 to 2.5 N / 25 mm, preferably 0.01 to 1 N / 25 mm, more preferably 0. It is 05-0.8N / 25mm.
The method of making the part other than the adhesion region weakly bonded to the cylindrical body 2 can be performed according to the eighth embodiment.
