Description

  The present invention relates to a heat-shrinkable cylindrical label that can favorably adhere a double part to an adherend such as a container.

2. Description of the Related Art Conventionally, packaging bodies in which a heat-shrinkable cylindrical label having a heat-shrinkable base material formed into a cylindrical shape is heat-shrink mounted on a container have been widely distributed. As such a package, for example, a bottle-type container filled with a beverage or the like and a heat-shrinkable cylindrical label mounted with heat-shrink can be used. The heat-shrinkable cylindrical label is also called a shrink label or a shrink tube.
Among such containers, there is also known a container in which a recessed portion whose outer surface is recessed inward is formed. Such a dent part can be used as a handle when the container is held by hand, for example.
However, when the heat-shrinkable cylindrical label is mounted including the dent portion of the container, the heat-shrinkable cylindrical label covers the dent portion so as to completely cover the dent portion. It becomes difficult.

In this regard, Patent Document 1 discloses that a heat-shrinkable cylindrical label is formed on the heat-shrinkable cylindrical label corresponding to the recessed portion of the container, and a portion surrounded by the perforation line is cut off during use. A package is disclosed in which a hole corresponding to the recess of the container can be formed in a part of the label.
Such a package can pour out the contents by holding the dent portion by hand through a hole formed in the heat-shrinkable cylindrical label.

  However, if the packaging body after forming the hole is used many times with a recess from the hole, the heat-shrinkable cylindrical label breaks from the peripheral edge constituting the hole. There is a point.

The first side end portion 21 and the second side end portion 22 are end portions facing each other in the lateral direction.
As described above, the first side end 21 and the second side end 22 of the heat-shrinkable base material 2 are overlapped to form the double portion 23 when the cylindrical body 3 is formed.
The lateral lengths of the first side end portion 21 and the second side end portion 22 of the heat-shrinkable substrate 2 (or heat-shrinkable film 4) are not particularly limited. Is relatively small, 3 mm to 20 mm is preferable, and 4 mm to 15 mm is more preferable. The lateral length of the double part 23 of the cylindrical body 3 is equal to the lateral length of the first side end portion 21 of the heat-shrinkable base material 2.

It is bonded by means, and the bonded portion is a seal portion S. The seal portion S is provided in a strip shape from the upper edge 3a to the lower edge 3b of the cylindrical body 3.
Although the horizontal length of the seal part S is not particularly limited, in order to bond the first side end part 21 and the second side end part 22 with sufficient adhesive strength, for example, 1 mm to 10 mm is preferable, and 2 mm to 8 mm. Is more preferable.

The first bonding means includes an outer surface of the first side end portion 21 and an inner surface (base) of the second side end portion 22 in the region from the side edge 22a of the second side end portion 22 to the midway portion of the double portion 23 in the lateral direction. The material is not particularly limited as long as the material can be bonded.

It has an adhesive strength that can be bonded between two objects, and can be re-adhered even after peeling (having adhesiveness even after peeling).

The (1) first adhering means comprises dissolving a resin material constituting the outer surface of the first side end portion 21 and the inner surface of the second side end portion 22 with a solvent interposed between the base materials in the region. It is to be glued. The solvent is not particularly limited as long as it can dissolve the resin material. For example, ether solvents such as tetrahydrofuran, dioxane and dioxolane; halogenated hydrocarbon solvents such as methylene chloride; alicyclic rings such as cyclohexane and methylcyclohexane. Aromatic hydrocarbon solvents; Ketone solvents such as acetone, methyl ethyl ketone, and methyl isobutyl ketone; Ester solvents such as ethyl acetate and methyl acetate; Aliphatic hydrocarbon solvents such as hexane; Aromatic hydrocarbon solvents such as toluene Is mentioned.
The first bonding means (2) interposes an adhesive between the base materials in the region, and bonds the outer surface of the first side end portion 21 and the inner surface of the second side end portion 22 through an adhesive layer. Is. The adhesive is not particularly limited as long as it can adhere the outer surface and the inner surface, and examples thereof include a solvent volatile adhesive, an ultraviolet curable adhesive, and a heat-sensitive adhesive.

The first adhering means (3) interposes an adhesive between the base materials in the region, and adheres the outer surface of the first side end portion 21 and the inner surface of the second side end portion 22 via the adhesive layer. Is. The pressure-sensitive adhesive is not particularly limited as long as it can adhere the outer surface and the inner surface, and examples thereof include a pressure-sensitive pressure-sensitive adhesive and a heat-sensitive pressure-sensitive adhesive.
Here, in this specification, a pressure-sensitive adhesive refers to an adhesive having an adhesive force at room temperature. A heat-sensitive adhesive and a heat-sensitive adhesive refer to a pressure-sensitive adhesive and an adhesive that do not have an adhesive force at room temperature and develop an adhesive force when heated.
A conventionally well-known thing can be used as a heat-sensitive adhesive and a heat-sensitive adhesive, for example, a hot melt type, a part coat type, a delayed tack type etc. are mentioned. The hot melt type does not have an adhesive force at room temperature but can be bonded by heating and can be applied by heating and melting. The part coat type does not have an adhesive force at room temperature, but can be bonded by heating, and is used after being coated and dried by a printing method. The delayed tack type is activated by heating to generate an adhesive force, and lasts for a long time after cooling, and can be applied by a printing method.

In the first bonding means (4), a double-sided adhesive tape is interposed between the substrates in the region, and the outer surface of the first side end portion 21 and the inner surface of the second side end portion 22 are bonded via the tape. Is.
Since the first side end portion 21 and the second side end portion 22 in the region can be firmly bonded and maintenance at the time of manufacturing the heat-shrinkable cylindrical label 1 is easy, the first bonding means is the above (1 ) It is preferable that the double portion 23 is welded between the base materials using a solvent.

  Various print layers 5 are provided on the heat-shrinkable base material 2 constituting the cylindrical body 3. The type of the printing layer 5 will be described later. The printing layer 5 is preferably provided on the inner surface of the heat-shrinkable film 4, and more preferably is provided on the inner surface excluding the seal portion S. Thus, when the printing layer 5 is not provided in the seal | sticker part S, a printing layer does not intervene between the base materials which comprise the seal | sticker part S, and the surfaces of the base material itself are firmly in the 1st adhesion | attachment means. It comes to adhere to.

Specifically, the printing layer 5 is provided on the inner surface of the heat-shrinkable film 4 so that the first side edge 5 a of the printing layer 5 substantially coincides with the side edge 21 a of the first side end portion 21.
Further, the printing layer 5 is provided on the inner surface of the heat-shrinkable film 4 (not shown) so that the second side edge 5b of the printing layer 5 coincides with the boundary of the seal portion S. Alternatively, as shown in FIG. 3 (and FIG. 4), the second side edge 5 b of the printing layer 5 is slightly separated from the boundary of the seal portion S, and the printing layer 5 is provided on the inner surface of the heat-shrinkable film 4. When the printing layer 5 is provided with the second side edge 5b slightly separated from the boundary of the seal portion S, the second side edge 5b is preferably included in the double portion 23, more preferably, More preferably, it is contained in the double part 23 excluding the side edge 21a. Since the second side edge 5a of the print layer 5 is located in the double portion 23, the print layer 5 exists over the entire lateral direction of the double portion 23 as shown in FIG. 3 (and FIG. 4). The printing layer 5 can be prevented from being interrupted at the double portion 23.

Of the double portion 23, all or part of the region other than the seal portion S is bonded by the second bonding means. The second bonding means is different from the first bonding means.
The second bonding means is different from the first bonding means, and is particularly limited as long as it can bond the outer surface of the first side end portion 21 and the inner surface of the second side end portion 22 in a region other than the seal portion S. Not.
As the second bonding means, similarly to the first bonding means, (a) welding between the base materials of the double part 23 using a solvent, (b) between the base parts of the double part 23 using an adhesive. Adhesion, (c) Adhesion between substrates of double part 23 using adhesive, (d) Adhesion between substrates of double part 23 using double-sided adhesive tape, (e) Melting substrate with heat And heat welding between the substrates.
Since the second bonding means is different from the first bonding means, for example, when the first bonding means is (1), the second bonding means is used by means other than the above (a). When the first adhering means is (2) above, means other than the above (b) are used as the second adhering means.
Preferably, the first bonding means is (1) above, the second bonding means is (b) or (c), more preferably, the first bonding means is (1) above, and the second bonding The means is adhesion between the substrates using the heat-sensitive adhesive or heat-sensitive adhesive in the above (b) or (c).

  When the second bonding means is bonding using a heat-sensitive adhesive or a heat-sensitive adhesive, the outer surface of the first side end 21 and the second side end in a region other than the seal portion S as shown in FIG. A heat-sensitive adhesive layer or a heat-sensitive adhesive layer 7 is interposed between the inner surfaces of 22 (between the base materials). Since the heat-sensitive adhesive or the heat-sensitive adhesive does not exhibit adhesiveness unless heated, before the heat-shrinkable cylindrical label 1 is heated, as shown in FIG. The first side end 21 is not bonded (in contact but not bonded). However, as will be described later, the heat-sensitive adhesive or heat-sensitive adhesive constituting the layer 7 is activated by heating when the heat-shrinkable cylindrical label 1 is attached to the adherend, and the heat-sensitive adhesive layer or heat-sensitive adhesive is activated. The outer surface of the first side end portion 21 and the inner surface of the second side end portion 22 are bonded via the agent layer 7 so as not to be easily peeled off. That is, when the second bonding means is bonding using a heat-sensitive adhesive or a heat-sensitive adhesive, the reinforcing portion T of the heat-shrinkable cylindrical label 1 is configured by heating when being attached to the adherend. The Therefore, when the second bonding means is bonding using a heat-sensitive adhesive or a heat-sensitive adhesive, a part or the whole of the region other than the seal portion S is a reinforcing portion that can be bonded by the second bonding means, When the shrinkable cylindrical label 1 is attached to the adherend, a part or the whole of the region other than the seal portion S becomes the reinforcing portion T bonded by the second bonding means. The bonded reinforcing portion T is in a state as shown in FIG. Since the heat-shrinkable cylindrical label according to claim 1 includes any state before heat shrinkage or after heat shrinkage, the reinforcing portion can be bonded by the second adhesive means before heat shrinkage as described above. Even in this case, the reinforcing portion and the reinforcing portion bonded before heat shrinkage are collectively referred to, and in claim 1, all or part of the region other than the seal portion S is used as the bonding means. It is expressed as a reinforcing portion T to be bonded.

  In the case where the second bonding means is bonding using a heat-sensitive adhesive or a heat-sensitive adhesive, a heat-sensitive adhesive is preferably used. According to the heat-sensitive adhesive, after the outer surface of the first side end portion 21 and the inner surface of the second side end portion 22 in the region other than the seal portion S are bonded by heating (that is, the reinforcing portion T in which the substrates are bonded to each other). Since the solidification occurs when the temperature returns to room temperature, the progress of the breakage of the label can be particularly suppressed.

  In the case where the second bonding means is bonding using an adhesive or pressure sensitive adhesive other than the heat sensitive adhesive or the heat sensitive pressure sensitive adhesive, as shown in FIG. An adhesive layer or a pressure-sensitive adhesive layer 71 is interposed between the outer surface and the inner surface (between the base materials) of the second side end portion 22. Through such an adhesive layer or pressure-sensitive adhesive layer 71, the outer surface of the first side end portion 21 and the inner surface of the second side end portion 22 in the region other than the seal portion S are bonded so as not to be easily peeled off, and the reinforcing portion T is constructed.

The reinforcing portion T is provided in a strip shape from the upper edge 3a to the lower edge 3b of the cylindrical body 3.
The formation range in the lateral direction of the reinforcing portion T may extend over the entire double portion of the region other than the seal portion S. In this case, the formation range in the lateral direction of the reinforcing portion T is from the side edge 21a of the first side end portion 21 to the boundary of the seal portion S (not shown). The reinforcing portion T in this case is bonded by the second bonding means in a state where the printing layer 5 is interposed between some or all of the substrates.

The formation range in the lateral direction of the reinforcing portion T may be a part of the region other than the seal portion S. In this case, the formation range in the lateral direction of the reinforcing portion T is (A) from the side edge 21a of the first side end portion 21 to a position closer to the side edge 21a than the boundary of the seal portion S. From the position closer to the seal portion S than the side edge 21a of the side end portion 21 to the boundary of the seal portion S, (C) from the position closer to the seal portion S than the side edge 21a of the first side end portion 21 It is either up to the position closer to the side edge 21a than the boundary of S.
In any of the cases (A) to (C), the reinforcing portion T is preferably bonded by the second bonding means in a state where the printing layer 5 is interposed between some or all of the substrates.
Although the horizontal direction length of the said reinforcement part T is not specifically limited, For example, they are 1 mm-10 mm, Preferably, they are 2 mm-8 mm.

When the heat-shrinkable cylindrical label 1 is heated, the region other than the seal portion S in the double portion 23 is less likely to shrink in a disorderly manner. It is preferable that the entire region is or (A). Moreover, since the seal part S and the reinforcement part T are easily formed separately, the formation range in the lateral direction of the reinforcement part T is more preferably (A). In FIG. 3 (and FIG. 4), the case where the reinforcement part T is formed in the range of the said (A) is illustrated.
In this case, the inner edge of the reinforcing portion T may substantially coincide with the second side edge 5b of the printing layer 5, but preferably, as shown in FIG. 3 (and FIG. 4), the inner edge of the reinforcing portion T is The reinforcing portion T is provided so as to be displaced from the second side edge 5b of the printing layer 5 to the side opposite to the seal portion S. In this case, in the double part 23, a non-bonded portion W where the first side end portion 21 and the second side end portion 22 are not bonded is slightly generated between the reinforcing portion T and the seal portion S. The lateral length of the non-bonded portion W is not particularly limited, but is, for example, more than zero and 5 mm or less.

Moreover, the adherend adherent first layer 61 is provided on a part or the whole of the inner surface of the cylindrical body 3.
The first adherend adherence layer 61 is formed by applying an adhesive or a pressure-sensitive adhesive. Although it does not specifically limit as said adhesive agent or an adhesive, For example, a heat sensitive adhesive, a heat sensitive adhesive, or a pressure sensitive adhesive is mentioned. Since it does not have adhesive force at normal temperature and is easy to handle, it is preferable that the first adherend-adhering first layer 61 is formed of a heat-sensitive adhesive or a heat-sensitive adhesive. In this case, the first adherend-adhering layer 61 is a heat-sensitive adhesive layer or a heat-sensitive adhesive layer.
The formation range in the longitudinal direction of the adherend adherent first layer 61 is not particularly limited, and may be provided in a strip shape from the upper edge 3a to the lower edge 3b of the cylindrical body 3, or the cylindrical body. 3 may be provided in a strip shape from the upper edge 3a to the midway portion in the longitudinal direction, or may be provided in a strip shape from the lower edge 3b of the tubular body 3 to the midway portion in the longitudinal direction, or the tubular body. 3 may be provided in a band shape in the longitudinal intermediate region not including the upper edge 3a and the lower edge 3b. Preferably, the adherend-adhering first layer 61 is provided in a strip shape from the upper edge 3 a to the lower edge 3 b of the cylindrical body 3. Further, the first adherend-adhering layer 61 may be formed continuously in the longitudinal direction or may be formed intermittently.

The formation range in the lateral direction of the adherend-adhering first layer 61 only needs to include at least a part of the inner surface of the double portion 23.
For example, the formation range in the lateral direction of the adherend-adhering first layer 61 is (i) the entire inner surface of the double portion 23, (ii) the inner surface corresponding to the reinforcing portion T (this inner surface is the double portion 23). (Iii) part or whole of (included in the inner surface), (iii) part or whole of the inner surface corresponding to the seal portion S (this inner surface is included in the inner surface of the double part 23), and (iv) the reinforcing portion T A part or the whole of the corresponding inner surface and a part of the inner surface corresponding to the seal portion S, (v) a part of the inner surface corresponding to the reinforcing portion T and a part or the whole of the inner surface corresponding to the seal portion S, etc. It is done. In the case of (iv) and (v), the first layer 61 provided corresponding to the reinforcing portion T and the first layer 61 provided corresponding to the seal portion S are connected to each other and are continuous. Or they may be independent of each other.
The first adherend adherence layer 61 is preferably formed over the entire inner surface corresponding to the reinforcing portion T, and more preferably from the inner surface corresponding to the reinforcing portion T to the inner surface corresponding to the seal portion S. Is formed. In the illustrated example, the first adherend adherence layer 61 is provided from the entire inner surface corresponding to the reinforcing portion T to the entire inner surface corresponding to the seal portion S (in other words, the entire inner surface of the double portion 23). . In addition, the formation range in the lateral direction of the adherend adherent first layer 61 may extend from the inner surface corresponding to the seal portion S to the inner surface of the single portion.
The lateral length of the adherend-adhering first layer 61 is not particularly limited, but if it is too small, the adhesion area to the adherend becomes relatively small, preferably 2 mm to 25 mm, more preferably 3 mm to 20 mm. preferable.

Furthermore, the adhesive layer or adhesive layer 62 for making it adhere | attach to a to-be-adhered body is provided in the inner surface of the single site | part following the side edge 21a of the 1st side edge part 21 among the inner surfaces of the cylindrical body 3.

The adherend adherent second layer 62 is formed by applying an adhesive or a pressure-sensitive adhesive. Although it does not specifically limit as said adhesive agent or an adhesive, For example, a heat sensitive adhesive, a heat sensitive adhesive, or a pressure sensitive adhesive is mentioned. The second layer 62 for adherend adherend is preferably formed of a heat-sensitive adhesive or a heat-sensitive adhesive because it does not have an adhesive force at normal temperature and is easy to handle. In this case, the adherend-adhering second layer 62 is a heat-sensitive adhesive layer or a heat-sensitive adhesive layer.

The formation range in the vertical direction of the adherend-adhering second layer 62 is not particularly limited, and may be provided in a strip shape from the upper edge 3a to the lower edge 3b of the cylindrical body 3, or the cylindrical body. 3 may be provided in a strip shape from the upper edge 3a to the midway portion in the longitudinal direction, or may be provided in a strip shape from the lower edge 3b of the tubular body 3 to the midway portion in the longitudinal direction, or the tubular body. 3 may be provided in a band shape in the longitudinal intermediate region not including the upper edge 3a and the lower edge 3b. Preferably, the adherend-adhering second layer 62 is provided in a strip shape from the upper edge 3a to the lower edge 3b of the cylindrical body 3.
The lateral length of the adherend-adhering second layer 62 is not particularly limited, and is, for example, 1 mm to 10 mm.
The heat-sensitive adhesive or heat-sensitive adhesive constituting the preferred adherend-adhering second layer 62 is the same heat-sensitive adhesive or heat-sensitive adhesive as the heat-sensitive adhesive or heat-sensitive adhesive constituting the preferred adherend-adhering first layer 61. You may form using a heat sensitive adhesive, or you may form using a different heat sensitive adhesive or heat sensitive adhesive.
Further, when the second bonding means is adhesion between substrates using a heat sensitive adhesive or a heat sensitive adhesive, the preferred heat sensitive adhesive layer or heat sensitive adhesive layer that is the second adherend-adhering second layer 62. Is preferably formed of the same heat-sensitive adhesive or heat-sensitive adhesive as the heat-sensitive adhesive layer or heat-sensitive adhesive layer of the second bonding means. In this case, conceptually, the heat-sensitive adhesive layer or the heat-sensitive pressure-sensitive adhesive layer of the second bonding means extends beyond the side edge 21a of the first side end portion 21 to the inner surface of the single portion, thereby applying the coating. A second body bonding layer 62 is formed.

  The adherend-adhering first layer 61 and the adherend-adhering second layer 62 may be independently formed of either an adhesive or a pressure-sensitive adhesive, but as described above, Is composed of either a heat sensitive adhesive or a heat sensitive adhesive, more preferably a heat sensitive adhesive. Due to the adhesive strength of the adhesive, the heat-shrinkable cylindrical label 1 is easily adhered to the outer surface of the adherend such as a container via the first adherend-adhering layer 61 and the second adherend-adhering layer 62. .

As shown in FIGS. 5 and 6, the heat-shrinkable base material 2 constituting the heat-shrinkable cylindrical label 1 is composed of a heat-shrinkable film 4, a printing layer 5, Have Here, in this specification, heat shrinkability refers to a property of shrinking when heated to a predetermined heat shrink temperature (for example, 70 ° C. to 120 ° C.).
For example, as shown in FIG. 4, the heat-shrinkable substrate 2 is formed in a substantially rectangular shape in plan view.
As the heat-shrinkable film 4, for example, a film that can be largely heat-shrinked in the horizontal direction (the horizontal direction is the circumferential direction when the cylindrical body 3 is used; hereinafter the same) is used. The heat-shrinkable film 4 may slightly heat shrink or slightly heat expand in the vertical direction (the vertical direction is a direction perpendicular to the horizontal direction in the plane of the film). Examples of the heat-shrinkable film 4 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 a series resin can be used. Since the shrinkage stress is large and relatively firm, it is preferable to use a film containing a polyester resin as the heat-shrinkable film 4, and it is more preferable to use a film containing a polyethylene terephthalate resin. The heat-shrinkable film 4 may have a heat-shrink property and a self-stretch property. The self-stretching property refers to a property that stretches when pulled at room temperature and restores to its original state when the tensile force is released.

The heat-shrinkable film 4 may be composed of a single layer film (single layer film), or may be composed of a film (laminated film) in which two or more layers are laminated and integrated. When the heat-shrinkable film 4 is a laminated film, each layer of the laminated film can be arbitrarily selected. As the laminated film, a laminated film in which two or more kinds of film layers having heat shrinkability are laminated, a laminated film in which a transparent gas barrier layer is laminated on a film layer having heat shrinkability, and the like can be used. When the heat-shrinkable film 4 is a laminated film, the material of each film layer may be substantially the same or different. The single-layer film is preferably a film containing a polyester resin (preferably, a polyethylene terephthalate resin), and the laminated film has at least one layer containing a polyester resin (preferably a polyethylene terephthalate resin). preferable.
Although the thickness of the heat-shrinkable film 4 is not specifically limited, For example, they are 20 micrometers-120 micrometers, Preferably they are 30 micrometers-80 micrometers.

The heat-shrinkable film 4 mainly heat-shrinks in the horizontal direction (the main heat-shrink direction is the horizontal direction).
The heat shrinkage rate in the transverse direction of the heat-shrinkable film 4 is, for example, 20% or more, preferably 30% or more, more preferably 40% or more. When the heat-shrinkable film 4 is a film that slightly heat shrinks or expands in the vertical direction, the heat shrinkage rate in the vertical direction is preferably −3% to 15%.
However, the heat shrinkage rate is the ratio of the length of the film before heating (original length) and the length of the film after immersion for 10 seconds in warm water at 90 ° C. (length after immersion). It is obtained by substituting into the following formula.
Heat shrinkage rate (%) = [{(original length in horizontal or vertical direction) − (length after immersion in horizontal or vertical direction)} / (original length in horizontal or vertical direction) ] × 100.
The heat-shrinkable film 4 may be non-transparent, but when the printing layer 5 is provided on the inner surface side, a film having excellent transparency is used. The transparency index of the transparent (colorless transparent or colored transparent) heat-shrinkable film 4 is 70% or more of the total light transmittance, 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).

  Various print layers 5 are provided on the heat-shrinkable film 4. As the printing layer 5, a design printing layer representing a design; a pattern-free one-color printing layer provided for the purpose of highlighting the design; a light-shielding layer that imparts light-shielding properties to the heat-shrinkable film 4; a heat-shrinkable film 4 A printed layer containing a sliding component that is provided on the back surface and improves the sliding property when the heat-shrinkable cylindrical label 1 is attached to an adherend; a protective layer that protects the outer surface of the heat-shrinkable film 4 . These printing layers 5 can be used alone or in combination of two or more. The 1 type (s) or 2 or more types of printing layers 5 may be provided in the outer surface side of the heat-shrinkable film 4, or may be provided in the inner surface side. Moreover, when the printing layer 5 is 2 or more types, those printing layers 5 may be separately provided on the outer surface side and the inner surface side of the heat-shrinkable film 4. Moreover, when the printing layer 5 is 2 or more types, those printing layers 5 may be provided so that the whole or one part may overlap with the thickness direction of the heat-shrinkable film 4, or a heat-shrinkable film. 4 may be provided continuously in the surface direction of 4 or at intervals, or a part of them may overlap in the thickness direction of the heat-shrinkable film 4 and the remaining portion may be provided continuously in the surface direction. It may be. In the illustrated example, the print layer 5 is provided on the inner surface of the heat-shrinkable film 4. Such a printing layer 5 usually includes a design printing layer and a patternless one-color printing layer provided on the inner surface side of the design printing layer, but in the illustrated example, one printing layer 5 is included. It is represented by

The printed layer 5 is a region excluding the region that becomes the seal portion S (the region from the side edge 22a of the second side end portion 22 to the midway portion of the double portion 23 when the cylindrical body 3 is formed). Are provided in whole or in part. Preferably, the printing layer 5 is provided such that the first side edge 5 a of the printing layer 5 substantially coincides with the side edge 21 a of the first side end portion 21 of the heat-shrinkable film 4, and further, The two side edges 5b are provided so as to be slightly separated from the boundary of the seal portion S of the heat-shrinkable film 4. In addition, if the 1st side edge 5a and the 2nd side edge 5b of the printing layer 5 are provided to such a position, the area | region where the printing layer 5 is not provided in the center part of the heat-shrinkable film 4, etc. You may have. In the illustrated example, the printed layer 5 has its first side edge 5a located on the side edge 21a of the first side end 21 of the heat-shrinkable film 4 and its second side edge 5b slightly away from the boundary of the seal part S. The heat shrinkable film 4 is provided so as to be separated.
In addition, the 1st side edge part 21 and the 2nd side edge part 22 of the heat-shrinkable film 4 point out the same location as the 1st side edge part 21 and the 2nd side edge part 22 of the heat-shrinkable base material 2. FIG.

Further, a heat-sensitive adhesive layer or a heat-sensitive adhesive layer 63 is provided on the inner surface of the first side end portion 21 of the heat-shrinkable substrate 2. The heat-sensitive adhesive layer or the heat-sensitive adhesive layer 63 corresponds to the preferable first layer 61 for bonding adherends.
In the illustrated example, the heat-sensitive adhesive layer or the heat-sensitive adhesive layer 63 is provided in a strip shape with a predetermined length in the lateral direction from the side edge 21a of the first side end 21 and over the entire vertical direction.
Furthermore, a heat-sensitive adhesive layer or a heat-sensitive adhesive layer 64 is provided on the inner surface of the second side end portion 22 of the heat-shrinkable substrate 2 and the inner surface in the vicinity thereof. The heat-sensitive adhesive layer or the heat-sensitive adhesive layer 64 corresponds to the above-described heat-sensitive adhesive layer or heat-sensitive adhesive layer 7 which is the second bonding means, and the preferable second layer 62 for adherend adhesion.

In the illustrated example, the heat-sensitive adhesive layer or the heat-sensitive adhesive layer 64 has a predetermined length in the lateral direction from the position closer to the inner side than the second side edge 5b of the print layer 5 (the lateral length of the reinforcing portion T + the covering length). The second layer 62 for bonding the body is equivalent to the length in the horizontal direction) and is provided in a strip shape over the entire vertical direction.
Therefore, between the side edge 22a of the second side end portion 22 and the second side edge 5b of the printing layer 5, a film exposed portion 29 where the inner surface of the heat-shrinkable film 4 is exposed is generated in the vertical direction.
The film-exposed portion 29 of the heat-shrinkable substrate 2 is subjected to a first bonding means such as a solvent or an adhesive so that the inner surface of the heat-shrinkable substrate 2 is inside and the heat-shrinkable substrate 2 is formed into a cylindrical shape. The cylindrical body is formed by superposing the back surface of the second side end portion 22 on the outer surface of the first side end portion 21 and bonding the base material of the double part 23 with the first bonding means and the second bonding means. 3 is formed. The solvent or adhesive of the first bonding means may be applied to the film exposed portion 29 of the heat-shrinkable substrate 2 after making the heat-shrinkable substrate 2 into a cylindrical shape.
When heat welding (5) or (e) is used as the first bonding means or the second bonding means, the heat-shrinkable base material 2 is formed into a cylindrical shape and then heated with a seal bar. What is necessary is just to weld a space.

The heat-shrinkable cylindrical label 1 can be manufactured, for example, by the following method.
As shown in FIG. 7, the base material 2 </ b> A is drawn from a roll of a long heat-shrinkable base material 2 </ b> A (hereinafter referred to as a base material 2 </ b> A). This base material 2A is conceptually a plurality of the heat-shrinkable base materials 2 continuously connected in the vertical direction, and is long except for the film exposed portion 29A at the second side end. 5A and a heat-sensitive adhesive layer or heat-sensitive adhesive layers 63A and 64A are provided in the longitudinal direction (longitudinal direction) on the back surface of the heat-shrinkable film. After the first adhesive means such as a solvent is applied to the film exposed portion 29A of the base material 2A through the coating machine X (in FIG. 7, innumerable dots are added to the coating portion), the base material By rolling the 2A into a cylindrical shape, the inner surface of the second side end portion 22A is overlapped on the outer surface of the first side end portion 21A and bonded by the first bonding means or the like, whereby the cylindrical elongated body 3A is obtained. The step of applying the first adhering means and the step of rounding the base material 2A into a cylinder may be performed sequentially or substantially simultaneously.
The cylindrical elongated body 3A is like a precursor of the heat-shrinkable cylindrical label 1 and is conceptually formed by continuously connecting a plurality of heat-shrinkable cylindrical labels 1.
By cutting the cylindrical elongated body 3A into a predetermined length, the heat-shrinkable cylindrical label 1 of the present invention as shown in FIGS. 1 to 3 is obtained.

The heat-shrinkable cylindrical label 1 of the present invention is used by being attached to various adherends.
The adherend is not particularly limited, and representative examples include sanitary containers such as beverage containers, seasoning containers, and shampoos, detergent containers, cosmetic containers, and pharmaceutical containers.
Moreover, since the heat-shrinkable cylindrical label 1 of the present invention can be heat-shrinkable and attached to the adherend while adhering the double part 23 to the adherend, a hole is formed in a part of the heat-shrinkable tubular label 1. It is effective to use it for the purpose of forming.
For example, the heat-shrinkable cylindrical label 1 of the present invention is attached to a container 9 having a recess 91 as shown in FIGS.

The container 9 includes a main body 92 having a storage space for storing contents, and a lid portion 93 that closes the spout of the main body 92, and a recessed portion 91 is formed in a part of the main body 92.
The main body 92 has a bottom portion 94 for allowing the container 9 to be self-supporting, and the container 9 can be self-supporting with the bottom portion 94 down as shown in the figure. The outer shape of the main body 92 is not particularly limited, and is substantially columnar, substantially elliptical, substantially polygonal, such as substantially rectangular or triangular, substantially conical, such as substantially conical or triangular, or substantially truncated cone. Or a substantially frustum shape such as a substantially quadrangular frustum shape, a substantially bowl shape, a substantially daruma shape, or a three-dimensional shape in which these shapes are combined.

The said recessed part 91 is a part of the external shape of the container 9, Comprising: The part recessed inside rather than the circumference | surroundings is said. The heat-shrinkable cylindrical label 1 subjected to heat shrinkage is attached to the container 9 by being in close contact with the outer surface of the main body 92 excluding the recessed portion 91. That is, the recessed portion 91 is a portion of the outer surface of the main body 92 that is not in contact with the heat-shrinkable cylindrical label 1 that is heat-shrinked.
The peripheral edge 91a of the recessed portion 91 forms an endless annular line in a front view. The front view shape of the recessed portion 91 is not particularly limited, and is substantially circular, substantially elliptical, substantially polygonal, such as substantially square or substantially triangular, substantially daruma, or a combination of these shapes. Is mentioned.
The recess 91 is formed in the main body 92 at one place or two places. In the illustrated example, two recesses 91 are formed. One recess 91 is formed on the front side of the main body 92, and the other recess 91 is formed on the back side of the main body 92.
For example, the two recesses 91 are formed at the same position on the front and back surfaces of the container 9, and thus the two recesses 91 appear to overlap each other when viewed from the front.

By forming the recessed portion 91, the side portion of the main body 92 (the upper right portion when viewed from the front) is easily gripped by hand. This side portion is a handle portion 95 that can be used as a handle. The handle portion 95 extends in the vertical direction on the side of the main body 92.
In the illustrated example, the two recessed portions 91 do not have a recessed bottom surface and communicate with each other. For this reason, a through-hole portion is formed between the two recessed portions 91. The handle portion 95 is separated from the main portion of the main body 92 through the through-hole portion. However, the two recessed portions 91 may not communicate with each other and may each have a recessed bottom surface (not shown).
The handle portion 95 forms part of the main body 92, and the inside of the handle portion 95 is hollow. Therefore, the inside of the handle portion 95 forms a part of the storage space of the main body 92. However, the handle portion 95 may be solid. In addition, the handle portion 95 is not limited to being formed integrally with the main body 92, and the handle portion and the through hole portion may be formed by attaching a separate handle portion 95 to the main body 92 ( Not shown).

The said container 9 is not specifically limited in the viewpoint of the material, A synthetic resin, glass, earthenware, a metal, etc. are mentioned. Considering the adhesion between the adherend-adhering first layer 61 and the adherend-adhering second layer 62, the main body 92 preferably has an outer surface portion formed of a polyester resin.
Here, the “formed from a polyester resin” means formed from a material mainly composed of a polyester resin. The “main component” refers to the most resin (weight ratio) among the resins contained in the material. For example, the main component resin is contained in an amount of 50% by weight or more, preferably 70% by weight or more, more preferably 80% by weight or more when the total amount of the resin contained in the material is 100% by weight.

Examples of the polyester resin that is a preferable material for forming the outer surface portion include polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, polylactic acid, and modified products thereof, and polyethylene terephthalate and modified products thereof are preferable. The outer surface portion preferably contains substantially no resin other than the polyester-based resin, but may contain other resins. Examples of resins other than the polyester resins include polyolefin resins, polystyrene resins, vinyl chloride resins, polycarbonate resins, polyamide resins, and thermoplastic elastomers.
Moreover, the main body 92 of the container 9 may have a single-layer structure or a multilayer structure of two or more layers. When the main body 92 has a one-layer structure, the outer surface of the layer constitutes the outer surface portion, and when the main body 92 has a multilayer structure of two or more layers, the outermost layer constitutes the outer surface portion. .

  The contents filled in the container 9 are not particularly limited, and beverages such as juice, seasonings such as edible oil and soy sauce, sanitary products such as liquid detergents and refill shampoos, pharmaceuticals such as sanitizing alcohol, cosmetics, etc. Is mentioned. The contents of the contents are not particularly limited as long as they can be taken out of the storage space, and may be liquid (including liquid having a certain degree of viscosity) or granular.

As shown in FIGS. 10 and 11, a heat-shrinkable cylindrical label 1 opened in a cylindrical shape is placed on the outside of the container 9. Preferably, the heat-shrinkable cylindrical label 1 is sheathed on the container 9 so that the double portion 23 corresponds to the handle portion 95. Moreover, the heat-shrinkable cylindrical label 1 is packaged so that the two dents 91 of the container 9 are covered with the heat-shrinkable cylindrical label 1 when viewed from the front and the back. The heat-shrinkable cylindrical label 1 that is larger than the maximum diameter of the portion to which the container 9 is attached is not attached to the container 9 when the container 9 is packaged.
In addition, in FIG. 11, the layer structure of the heat-shrinkable cylindrical label 1 is not shown, but the heat-shrinkable cylindrical label 1 is represented by one layer (the same applies to FIG. 15).

Next, the heat-shrinkable cylindrical label 1 is heated to heat-shrink the heat-shrinkable cylindrical label 1. The heat-shrinkable cylindrical label 1 is reduced in diameter by heat shrinkage and is in close contact with the main body 92 of the container 9 (see FIG. 12).
When the adherend-adhering first layer 61 and the adherend-adhering second layer 62 are formed of a heat-sensitive adhesive layer or a heat-sensitive adhesive layer, by heating the heat-shrinkable cylindrical label 1, The first adherend adherence layer 61 and the adherend adherent second layer 62 are activated to generate an adhesive force, and the first layer 61 and the second layer 62 adhere to the outer surface of the container 9. In the case where the first adherend-adhering layer 61 and the second adherend-adhering layer 62 are formed of a pressure-sensitive adhesive layer, the heat-shrinkable cylindrical label 1 is reduced in diameter. The first body bonding layer 61 and the adherend bonding second layer 62 are pressed against the container 9, and the first layer 61 and the second layer 62 adhere to the outer surface of the container 9.
When the second bonding means is bonding using a heat-sensitive adhesive or a heat-sensitive adhesive, the layer is activated by the heating, and the base material in the region other than the seal portion S is bonded to the reinforcing portion T. Is configured.

  In addition, when the adherend-adhering first layer 61 is provided on the entire inner surface of the double part 23, the heat-shrinkable cylindrical label 1 is bonded to the adherend (adherent-adhering first layer 61. ) At least the entire double part 23 is bonded to the outer surface of the container 9. When the adherend adherent first layer 61 is provided on a part of the inner surface of the double part 23, the heat-shrinkable cylindrical label 1 has a part of the container 9 in the double part 23. Bonded to the outer surface.

  The heating temperature for the heat-shrinkable cylindrical label 1 can be set at a predetermined temperature, and is, for example, 60 ° C to 120 ° C, preferably 80 ° C to 110 ° C, based on the outer surface of the heat-shrinkable cylindrical label 1. It is. The heating means is not particularly limited, and examples thereof include steam and hot air of about 100 ° C to 250 ° C. As other heating means, heating using irradiation of active energy rays such as radiation, ultraviolet rays and infrared rays may be used.

In this way, a labeled container 10 as shown in FIG. 12 in which the heat-shrinkable cylindrical label 1 is mounted on the container 9 is obtained.
Although the labeled container 10 may be used as it is, it is preferable to form the opening 33 in the heat-shrinkable cylindrical label 1 as shown in FIGS. 13 to 16 in order to easily hold the handle portion 95. .
FIGS. 13 to 15 show the labeled container after the opening is formed, and FIG. 16 is an enlarged cross-sectional view around the handle portion of the labeled container.
The opening 33 can be formed by cutting out a portion corresponding to the recessed portion 91 in the mounted heat-shrinkable cylindrical label 1. The method for forming the opening 33 is not particularly limited, and examples include cutting using a melt cutting means such as a laser, cutting using a mechanical cutting such as a die cut, a cutter, and a water jet. Since the opening 33 having a shape can be easily formed, it is preferable to use a laser.
Type of laser, if Re as it can cut the heat-shrinkable tubular label 1 is not particularly limited, carbon dioxide gas laser, YAG laser, etc. YVO ₄ laser. In particular, a carbon dioxide laser is preferable because it is suitable for cutting the heat-shrinkable film 4 containing a polyester resin or the like. The wavelength of the carbon dioxide laser is not particularly limited, and examples thereof include those having a wavelength of 9.4 μm or 10.6 μm. Among these, a carbon dioxide laser having a wavelength of 10.6 μm is preferable.

For example, by opening the heat-shrinkable cylindrical label 1 along the peripheral edge 91a of the recess 91 using a cutting means such as a laser, an opening that leads to the recess 91 in the surface of the heat-shrinkable cylindrical label 1 33 can be formed. Preferably, as shown in FIG. 16, the edge 33 a of the opening 33 is bonded to the container 9 in the double portion 23 (in the illustrated example, the first layer 61 for adherend adherend and the second layer for adherend adherend). The opening 33 is formed so as to extend from the edges 61a and 62a of the layer 62). In the illustrated example, the heat-shrinkable cylindrical label 1 is adhered to the container 9 including the entire double part 23, but even if a part of the double part 23 is adhered to the container 9 as described above. Good. When the edge 33a is separated from the edges 61a and 62a of the adhesive portion as shown in FIG. 16, the whole or part of the inner surface of the double portion 23 is in the vicinity of the edge 33a of the opening 33 (in the illustrated example, The first layer 61 for adherend adhesion and the second layer 62 for adherend adherend are bonded to the outer surface of the container 9. Note that the opening 33 may be formed so that the edge 33a of the opening 33 coincides with the edges 61a and 62a of the adhesive portion. Even in this case, all or part of the inner surface of the double portion 23 is opened. In the vicinity of the edge 33a of the part 33, it adheres to the outer surface of the container 9 through an adhesive part.
However, since it is often difficult to accurately form the opening 33 so that the edge 33a coincides with the edges 61a and 62a of the bonding portion, the edge 33a of the opening 33 extends from the edges 61a and 62a of the bonding portion. It is preferable to form the opening 33 so as to be exposed.
The vicinity in the case where the whole or a part of the inner surface of the double portion 23 is bonded in the vicinity of the edge 33a of the opening 33 is not particularly limited, but for example, the edge 33a ′ of one opening 33 and the first The lateral length of the side edge 22a of the second side end 22 and the lateral length of the side edge 21a of the first side end 21 and the edge 33a '' of the other opening 33 are independently It exceeds 15 and is 15 mm or less, preferably 1 mm to 10 mm.

The edge 33 a of the opening 33 extends along the handle portion 95. The double portion 23 of the heat-shrinkable cylindrical label 1 attached is in close contact with the outer surface of the handle portion 95 and extends in the vertical direction within the handle portion 95.
By forming the opening 33, it becomes easy to hold the labeled container 10 by grasping the handle portion 95 by hand.

  In addition, the manufacturing method of the labeled container after forming the opening part shown in FIG. 13 thru | or FIG. 15 forms an opening part using the laser etc. in the heat-shrinkable cylindrical label 1 with which the above-mentioned container was mounted | worn. It is not limited to the method of doing. For example, an opening is formed at a desired position of the heat-shrinkable cylindrical label 1 before heat-shrinking, and the heat-shrinkable cylindrical label 1 having the opening is formed outside the container 9 as in FIGS. After covering, the container with a label may be produced by heating.

  In the heat-shrinkable cylindrical label 1 of the present invention, the base material in the region other than the seal portion S in the double portion 23 is bonded (the reinforcing portion T in which the region other than the seal portion S is bonded). Therefore, when heated, the first side end portion 21 in a region other than the seal portion S contracts in a disorderly manner, so that wrinkles and the like are less likely to occur. Furthermore, since the first adherend adherence layer 61 is provided on the inner surface corresponding to the reinforcing portion T, when heated, the adherend adherent first layer 61 is transferred to the container 9 (adherent object). Adhere to the outer surface of). Since the first adherend-adhering layer 61 is provided on the inner surface corresponding to the reinforcing portion T (region other than the seal portion S) that is difficult to shrink as described above, the adherend-adhering first layer 61 is used as a container. It can be made to adhere well to the outer surface of 9. In particular, since the reinforcing portion T is a part of the double portion 23, the first layer 61 for adhesion of the adherend is strongly pressed to the outer surface of the container 9 by the heat shrinkage force of the heat-shrinkable cylindrical label 1 and reliably. The first adherend adherence layer 61 can be adhered to the outer surface of the container 9. In this embodiment, since the adherend-adhering second layer 62 is also provided, the adherend-adhering second layer 62 is also adhered to the outer surface of the container 9, and the heat shrinkability over a wider range. A part of the inner surface of the cylindrical label 1 can be adhered to the container 9.

  About the labeled container 10 which has such a heat-shrinkable cylindrical label 1, when the handle part 95 is held and used, there exists a possibility of fracture | rupture from the edge 33a of the opening part 33. FIG. In this regard, in the labeled container 10 of the present invention, the double portion 23 of the heat-shrinkable cylindrical label 1 extends on the outer surface of the handle portion 95, and the heat-shrinkable cylindrical label 1 has at least the double portion 23. Since it is partially bonded to the container 9, even if it breaks from the edge 33 of the opening 33, the progress of the breakage of the heat-shrinkable cylindrical label 1 is prevented at the bonded portion.

  The present invention is not limited to the first embodiment described above, and can be appropriately modified within the scope intended by the present invention. Hereinafter, other embodiments of the present invention will be described. In the description, configurations and effects different from those of the first embodiment will be mainly described, and configurations similar to those of the first embodiment will be described. In some cases, the term or reference is used as it is, and the description of the configuration is omitted.

[Second Embodiment]
Each modification of the second embodiment is different from the specific example shown in the first embodiment in the configuration around the double portion 23 of the heat-shrinkable cylindrical label 1.
17 to 20 are enlarged cross-sectional views around the double portion 23 of the heat-shrinkable cylindrical label 1 according to various examples of the second embodiment. Since the general view of these heat-shrinkable cylindrical labels 1 is the same as that shown in FIGS. 1 and 2, it is omitted.

In FIG. 17, the adherend-adhering first layer 61 extends beyond the portion corresponding to the side edge 22 a of the second side end 22, and the adherend-adhering first layer 61 extends to the inner surface of the single portion. It is a modified example.
FIG. 18 is a modified example in which the adherend-adhering first layer 61 is provided on the inner surface corresponding to only the entire region other than the seal portion S. In other words, the adherend-adhering first layer 61 is provided only on the inner surface from the side edge 21a of the first side end portion 21 to the location corresponding to the boundary of the seal portion S.
FIG. 19 shows a modification in which the adherend-adhering second layer 62 is not provided.
FIG. 20 is a modification in which the reinforcing portion T is formed at a position closer to the seal portion S than the side edge 21 a of the first side end portion 21. FIG. 20 is a modification in which the heat-sensitive adhesive layer or heat-sensitive adhesive layer 7 or the adhesive layer or pressure-sensitive adhesive layer 71 of the second adhesive means is provided up to the second side edge 5b of the printing layer 5. is there.

Moreover, the labeled container 10 of the said embodiment is the adhesive layer or adhesive layer (adhered body) in which a part or all of the inner surface of the double part 23 of the heat-shrinkable cylindrical label 1 is provided on the inner surface. Although it adhere | attaches on the container 9 via the 1st layer 61 for adhesion | attachment and the 2nd layer 62 for adherend adherends, the container with a label of this invention is not restricted to this.
For example, by applying an adhesive or pressure-sensitive adhesive to the outer surface of the container 9 and attaching a heat-shrinkable cylindrical label so that the inner surface of the double part is located on the adhesive or pressure-sensitive adhesive, the heat-shrinkable cylindrical shape A label-attached container in which a part or the whole of the inner surface of the double portion of the label is bonded to the container via an adhesive layer or an adhesive layer may be used (not shown).
