[First Embodiment]
<Cylindrical shrink label with secondary label>
The cylindrical shrink label A with a sub-label according to the first embodiment will be described with reference to FIGS. 1 to 6. The tubular shrink label A with a sub-label includes a tubular shrink label 1 in which a heat-shrinkable heat-shrinkable film is formed in a tubular shape, a sheet-shaped sub-label 2 attached to the outer surface of the tubular shrink label 1, and a sheet-shaped sub-label 2. Have. The cylindrical shrink label A with a sub-label before being heat-shrink-mounted on an adherend such as a container usually extends in the vertical direction of the tubular shrink label 1 and faces each other as shown in FIGS. 1 to 5. At the pair of folds 19 and 19, it is folded flat. When the tubular shrink label A with a sub-label is attached to the adherend, the tubular shrink label 1 is opened three-dimensionally (for example, a three-dimensional shape such as a substantially cylindrical shape) as shown in FIG. In the column of <Cylindrical shrink label with sub-label>, the tubular shrink label 1 refers to a state before heat shrinkage (a state before being attached to an adherend).

In a realistic manufacturing process, the tubular shrink label A with a sub-label is a sheet-like continuum in which a plurality of them are continuously connected in the vertical direction, and is a long tubular shrink label original folded flat. It can be provided in the opposite form. By appropriately cutting this long tubular shrink label original fabric along the planned cutting line, a tubular shrink label A with a sub-label as shown in FIGS. 1 to 5 can be obtained.

The tubular shrink label 1 is a sheet-like flexible heat-shrinkable film formed in a tubular shape. The heat-shrinkable film is a film that shrinks in the heat-shrinkable direction when heated to a heat-shrinkable temperature. As the heat shrinkage temperature, for example, 60 ° C. to 120 ° C. is exemplified, and 80 ° C. to 110 ° C. is preferable.

Examples of the heat-shrinkable film include a heat-shrinkable synthetic resin film, a non-woven fabric, a foamed resin film, and a laminated film thereof. The laminated film may be a laminate of a layer having no heat shrinkage and a layer having heat shrinkability, provided that the laminate as a whole has heat shrinkage. The heat-shrinkable film is preferably a synthetic resin film or a synthetic resin laminated film, and more preferably a synthetic resin film or a synthetic resin laminated film containing no fiber-containing sheet such as a non-woven fabric (metal vapor deposition on this laminated film). Also includes films with layers).

The material of the synthetic resin film or the synthetic resin laminated film is not particularly limited, and is a polyester resin such as polyethylene terephthalate and polylactic acid; an olefin resin such as polypropylene and a cyclic olefin; and a polystyrene resin such as polystyrene and a styrene-butadiene copolymer. Resins; polyamide-based resins; one kind selected from thermoplastic resins such as vinyl chloride-based resins, or a mixture of two or more kinds can be mentioned. The synthetic resin film may be composed of one resin, or may be composed of a plurality of different resins of different types or the same type.

As the heat-shrinkable film, a film containing a polystyrene-based resin is preferable because it is relatively soft and easily torn along the line of sight of the perforation. Further, a polystyrene-based resin film or a polystyrene-based resin layer and a polyester-based resin layer are laminated. It is more preferable to use the laminated film. The heat-shrinkable film may be transparent or opaque, but a transparent film is preferably used. The thickness of the heat-shrinkable film is not particularly limited, but can be, for example, 8 μm to 100 μm, and can be particularly about 20 μm to 80 μm.

As the heat-shrinkable film, a film that mainly heat-shrinks in at least the first direction is used, and a film that slightly heat-shrinks or heat-stretches in the second direction may be used. The first direction means one direction in the plane of the film, and the second direction is the direction orthogonal to the first direction in the plane of the film. As the heat-shrinkable film, a uniaxially stretched or biaxially stretched film mainly stretched in the first direction can be used.

The heat shrinkage rate in the first direction (heat shrinkage direction) of the heat-shrinkable film is not particularly limited, but is preferably 20% or more, more preferably 30% or more, still more preferably 40% or more. .. The larger the heat shrinkage rate in the first direction is, the more preferable it is, but there is a limit to it, and the heat shrinkage rate in the first direction is theoretically less than 100%. When the heat-shrinkable film is a film that changes heat in the second direction, the heat-shrinkage rate in the second direction is, for example, -3 to 15%, preferably 0 to 10%. Negative heat shrinkage means heat elongation.

The heat shrinkage is the length of the film (original length) before heating (stored for 24 hours under standard conditions) and the length of the film after being immersed in warm water at 90 ° C for 10 seconds and taken out (after immersion). (Length) and are measured under standard conditions, respectively, and are obtained by substituting them into the following equations. The standard state is 23 ° C, 1 atm, 50% RH.
Heat shrinkage rate (%) = [{(original length in the first direction (or second direction))-(length after immersion in the first direction (or second direction))} / (first direction (or second direction) Or the original length)] x 100 in the second direction).

The film is rolled into a tubular shape so that the first direction (main heat shrinkage direction) of the heat-shrinkable film is the circumferential direction, and the first side end portion of the heat-shrinkable film is overlapped with the second side end portion. Adhere to form the seal portion 18. As a result, the tubular shrink label 1 is configured. The sealing portion 18 extends in a strip shape in the vertical direction of the tubular shrink label 1. The method of adhering the first side end portion and the second side end portion is not particularly limited, and examples thereof include welding using a solvent, adhesion using an adhesive, and heat welding. The circumference of the tubular shrink label 1 is, for example, more than the maximum circumference of the mounted portion of the adherend × 1 times and × 1.5 times or less, preferably the same × 1.01 times to the same × 1. It is .3 times, more preferably the same × 1.02 times to the same × 1.15 times.

If necessary, the heat-shrinkable film may be provided with a design print layer that represents a display of desired characters, patterns, or the like (the design print layer is not shown). A transparent heat-shrinkable film is used when the design print layer is provided on the back side of the heat-shrinkable film (the back side of the heat-shrinkable film becomes the inner surface when it is made into a tubular shrink label 1). Be done. In the present specification, transparent (colorless transparent or colored transparent) means a case where the total light transmittance is 70% or more, preferably 80% or more, and more preferably 90% or more. However, the total light transmittance refers to a value measured by a measuring method based on JIS K 7361 (test method for total light transmittance of plastic-transparent material). Further, the heat-shrinkable film may be provided with an arbitrary functional layer, if necessary. Examples of the functional layer include a surface protective layer and a sliding layer. The design print layer, the functional layer, and the like are conventionally known as constituent elements of the tubular shrink label 1, and the known configurations can be adopted in the present disclosure.

The tubular shrink label 1 is formed with a perforation line 3 extending in the vertical direction. Hereinafter, in order to distinguish between the perforation line formed on the tubular shrink label 1 and the perforation line formed on the sub-label 2, the former is referred to as "shrink perforation line" and the latter is referred to as "sub-label perforation line". Also called.

The shrink perforation line 3 may be extended parallel to the vertical direction of the tubular shrink label 1, or may be inclined at an acute angle (for example, 20 degrees or less) with respect to the vertical direction of the tubular shrink label 1. However, it may be extended in the vertical direction. A part of the shrink perforation line 3 inclined with respect to the vertical direction may be inclined, or the whole may be inclined. It should be noted that the shrink perforation line 3 whose part is inclined is non-linear, and the shrink perforation line 3 whose whole is inclined is linear. Preferably, the shrink perforation line 3 extends in a straight line parallel to the vertical direction.

The shrink perforation line 3 is composed of a line (a set of a plurality of through holes) in which through holes penetrating in the thickness direction of the film are intermittently formed. Therefore, in the shrink sewing machine line of sight 3, a non-penetrating portion (non-cutting portion) exists between adjacent through holes. That is, the shrink perforation line 3 is a line formed by alternately arranging through holes and non-penetrating portions. The shape of one through hole is generally substantially circular or linear, preferably linear. The length of one through hole is not particularly limited, but is, for example, 0.3 mm to 2.5 mm, preferably 0.5 mm or more and less than 2.5 mm, and the length of one non-penetration portion is. Although not particularly limited, it is, for example, 0.3 mm to 2.5 mm.

At least one shrink perforation line 3 is formed in the plane of the tubular shrink label 1, and preferably a plurality (two or more) are formed. In the illustrated example, three shrink perforations 3 are formed on the tubular shrink label 1. Hereinafter, in order to distinguish these shrink sewing machine lines in terms of terms, they are referred to as "first shrink sewing machine line of sight 31", "second shrink sewing machine line of sight 32" and "third shrink sewing machine line of sight 33", and are collectively referred to as "shrink sewing machine line of sight 33". 3 ".

It is preferable that the first shrink sewing machine line 31 and the second shrink machine line 32 are arranged close to each other in the lateral direction. That is, in the plane of the tubular shrink label 1 on which the perforation line extending in the vertical direction (first shrink perforation line 31) is formed, the second is located near the perforation line (first shrink perforation line 31). It is preferable that the perforation line (second shrink perforation line 32) is formed. The neighborhood means that the two shrink perforations 3 (first shrink perforation line 31 and the second shrink perforation line 32) do not overlap, and one shrink perforation line 3 (first shrink perforation line 31) is used as a reference. It means that one shrink sewing machine line of sight 3 (second shrink sewing machine line of sight 32) is located laterally (either the first side or the second side) with a distance of 3 mm or less from the reference.

The third shrink sewing machine line 33 is not particularly related in the lateral direction to the first shrink machine line 31 and the second shrink sewing machine line 32, and is formed at a considerable distance in the lateral direction from these shrink sewing machine lines 3. Has been done. When four or more shrink sewing machine lines 3 are formed (not shown), for the shrink sewing machine lines other than the first to third shrink sewing machine lines 31, 32, 33, one shrink sewing machine selected from them is used. It may be arranged at a position near the line of sight, or may be arranged at a position having no particular relationship in the lateral direction.

The shrink perforation line 3 may be formed from the first edge in the vertical direction to the second edge in the vertical direction separated in the vertical direction of the tubular shrink label 1, and may be formed from the first edge in the vertical direction to the second edge in the vertical direction. It may be formed over close to each other, from near the first vertical edge to near the second vertical edge, and from near the first vertical edge to near the second vertical edge. It may be formed over. Preferably, the first shrink perforation line 31 is formed from the first vertical edge of the tubular shrink label 1 to the second vertical edge. The perforation line formed over the entire vertical direction is particularly called "all vertical perforations".

The first vertical edge is one opening cylinder edge of the tubular shrink label 1, and the second vertical edge is the other opening cylinder edge. The length between the first vertical edge and the second vertical edge corresponds to the vertical length of the tubular shrink label 1. Near the first edge in the vertical direction means a range 3 mm to 10 mm in the vertical direction from the first edge, and near the second edge in the vertical direction means 3 mm to 10 mm in the vertical direction from the second edge in the vertical direction. Refers to the range.

The second shrink perforation line 32 may be a full vertical perforation or may be a line other than the full vertical perforation (such as a perforation line formed from the first edge to the second edge in the vertical direction). More preferably, the first shrink perforation line 31 and the second shrink perforation line 32 are all vertical perforations. When three or more shrink perforations 3 are formed, all vertical perforations or other than all vertical perforations may be used except for the first and second shrink perforations 31 and 32.

The sub-label 2 is in the form of a sheet. For example, the vertical length of the sub-label 2 and the vertical length of the cylindrical shrink label 1 are equal. As shown in the figure, the sub-label 2 has a vertical first end 21 and a vertical second end 22 facing each other at a distance in the vertical direction, and a horizontal first end 23 facing each other at a distance in the horizontal direction. And has a lateral second end. The vertical first end includes the vertical first edge, the vertical second end includes the vertical second edge, the horizontal first end includes the horizontal first edge, and the horizontal second end. The portion includes a lateral second edge. However, the front view shape of the sheet-shaped sub-label 2 is not limited to the front view substantially rectangular shape (or substantially square shape) as shown in the drawing, and may be a substantially trapezoidal shape, a substantially hexagonal shape, or the like.

The sub-label 2 is made of a flexible film. Preferably, as the sub-label 2, a film that does not substantially heat shrink in the lateral direction is used, and more preferably, a film that does not substantially heat shrink as a whole is used. Substantially no heat shrinkage means that there is almost no heat shrinkage at the heat shrinkage temperature of the heat shrinkable film (cylindrical shrink label 1). Expressed in terms of heat shrinkage, the film (secondary label 2) that does not substantially heat shrink has a heat shrinkage of 0 to 5% in the horizontal direction, preferably 0 in both the horizontal and vertical directions. ~ 5%. The meaning of the heat shrinkage rate is as described above.

The film constituting the sub-label 2 is not particularly limited as long as it is a flexible film, and for example, paper such as plain paper and high-quality paper; synthetic paper; synthetic resin film; a plurality of different or similar resin layers are laminated. Resin laminated film; non-woven fabric; foamed resin film; laminated film in which two or more kinds selected from these are laminated can be used. Examples of the resin material of the synthetic resin film or the resin laminated film include those exemplified in the heat-shrinkable film. The thickness of the film constituting the sub-label 2 is not particularly limited, and is, for example, 10 μm to 200 μm, preferably 20 μm to 150 μm.

The film constituting the sub-label 2 may be transparent or opaque, but a transparent film is preferably used. Synthetic paper is usually milky white and opaque, so if the film contains synthetic paper, the sub-label 2 will be opaque. Since the synthetic resin film is usually transparent, the sub-label 2 becomes opaque by applying opaque printing such as white solid printing or silver solid printing to the synthetic resin film. If necessary, the film constituting the sub-label 2 may be provided with a design print layer indicating a desired character, pattern, or the like on the outer surface side and / or the inner surface side thereof (the design print layer may be provided). Not shown).

The sub-label 2 is attached to the outer surface of the tubular shrink label 1 in the attachment area. When the vertical length of the tubular shrink label 1 and the vertical length of the sub-label 2 are equal, the first vertical edge of the sub-label 2 is viewed from the front (directly viewed from the direction along the perpendicular direction of the plane including the vertical direction and the horizontal direction). The vertical first edge of the tubular shrink label 1 coincides with the vertical second edge of the sub-label 2, and the vertical second edge of the sub-label 2 coincides with the vertical second edge of the tubular shrink label 1 in the front view. preferable. The vertical first edge and the vertical second edge of the sub-label 2 are opposite edges in the vertical direction, and the length between the vertical first edge and the second edge is the vertically long edge of the sub-label 2. Equivalent to. The sub-label 2 attached so that the vertical length of the tubular shrink label 1 and the vertical length of the sub-label 2 are equal to each other and the first edge in each vertical direction and the second edge in each vertical direction coincide with each other is a cylindrical shrink in the vertical direction. It does not stick out of the label 1.

The lower limit of the horizontal length of the sub-label 2 is not particularly limited, but if it is too small, the significance of attaching a separate sub-label 2 to the tubular shrink label 1 to expand the display area becomes relatively small. From this point of view, the horizontal length of the sub-label 2 is, for example, the horizontal length of the tubular shrink label 1 folded flatly × 1/5 or more, preferably the horizontal length × 1/4 or more. The upper limit of the horizontal length of the sub-label 2 is not particularly limited, but if it is too large, the balance between the tubular shrink label 1 and the sub-label 2 becomes unbalanced, and the flattened tubular shrink label 1 is located outside one crease 19. The sub-label 2 protrudes, resulting in poor handling. From this point of view, the horizontal length of the sub-label 2 is, for example, less than or equal to the horizontal length of the flatly folded tubular shrink label 1 (or less than the horizontal length of the flatly folded tubular shrink label 1), preferably the horizontally long ×. It is 4/5 or less. In a specific numerical value, the horizontal length of the sub-label 2 is, for example, 15 mm to 100 mm, although it depends on the size of the tubular shrink label 1. As shown in FIG. 1, the horizontal length of the tubular shrink label 1 means the horizontal length between the pair of creases 19 and 19, and this horizontal length is half the peripheral length of the tubular shrink label 1. ..

The horizontal length of the sub-label 2 in the illustrated example is smaller than the horizontal length of the cylindrical shrink label 1 folded in a flat shape. The sub-label 2 is attached to the outer surface of the tubular shrink label 1 so as not to protrude outside the tubular shrink label 1 in the lateral direction.

The sub-label 2 is arranged on the tubular shrink label 1 so as to cover at least one shrink perforation line 3 (preferably, the first shrink perforation line 31). Preferably, the sub-label 2 is arranged on the tubular shrink label 1 so as to cover the first shrink perforation line 31 and the second shrink perforation line 32.

Of the sub-labels 2 arranged as described above, the vertical first end portion 21, the vertical second end portion 22, and the horizontal first end portion 23 are independent regions independent of the tubular shrink label 1. Is. Of the sub-label 2, the area other than the independent area is the attachment area attached to the outer surface of the tubular shrink label 1. The attachment area of the sub-label 2 covers at least the first shrink sewing machine line 31 and preferably covers the first shrink machine line 31 and the second shrink machine line 32.

Here, the attached area refers to an area of the sub-label 2 that is in close contact with the outer surface of the tubular shrink label 1. The entire attachment area may be adhered to the outer surface of the tubular shrink label 1, or there may be a portion of the attachment area that is not adhered to the outer surface of the tubular shrink label 1. The "non-adhesive portion" in the attached region includes, for example, a portion other than the outer edge portion of the top region when the outer edge portion of the attached region is adhered to the outer surface. That is, the "non-adhesive portion" in the attached region has no or extremely low degree of freedom of movement with respect to the outer surface of the tubular shrink label 1. Further, the independent region means a region in which the entire region is non-adhesive to the outer surface of the tubular shrink label 1 and is separated from the outer surface of the tubular shrink label 1. That is, the independent region has a high degree of freedom of movement with respect to the outer surface of the tubular shrink label 1. Note that adhesion refers to a state in which the sub-label 2 is bonded to the tubular shrink label 1 by physical or / or chemical force, and non-adhesion refers to a state in which the sub-label 2 does not have the above-mentioned bond. ..

The vertically long 21H and 22H of the vertical first end portion 21 and the vertical second end portion 22 of the sub-label 2 which are independent regions are cylinders when the cylindrical shrink label A with the sub-label is attached to the adherend. It is preferable that the length corresponds to the bent portion of the shrink label 1. As a specific numerical value, the vertically long 21H and 22H of the vertical first end portion 21 and the vertical second end portion 22 of the sub-label 2 are independently, for example, 2 mm or more, preferably 5 mm or more. be. On the other hand, if the vertically long 21H and 22H are too large, the vertically long portion of the attached area becomes relatively too small. 22H is independently, for example, 20 mm or less, preferably 10 mm or less.

The horizontally long 23W of the first lateral end portion 23 of the sub-label 2 which is an independent region is not particularly limited. However, if the horizontally long 23W is too small, it becomes difficult to pick the first lateral end portion 23 of the sub-label 2 when the tubular shrink label A with the sub-label is attached to the adherend, and if it is too large, it is relatively The horizontal length of the attached area becomes too small. From this point of view, when the horizontal length of the sub-label 2 is 15 mm to 100 mm as described above, the horizontal length 23W of the first lateral end portion 23 of the sub-label 2 is 10 mm to 90 mm, preferably 20 mm to 80 mm. Is. Vertical length of the attached area = vertical length of the sub-label 2- (vertical length 21H of the vertical first end portion 21 of the sub-label 2 + vertical length 22H of the vertical second end portion 22 of the sub-label 2), horizontal length of the attached area = sub The horizontally long label 2 − the horizontally long 23W of the first horizontal end portion 23 of the sub-label 2 in the horizontal direction.

The attached area of the sub-label 2 may be entirely adhered to the tubular shrink label 1, and both ends in the lateral direction sandwiching at least one shrink perforation line 3 (first shrink perforation line 31) are tubular. It may be adhered to the shrink label 1, and both lateral portions sandwiching the first shrink perforation line 31 and the second shrink perforation line 32 may be adhered to the tubular shrink label 1. In the illustrated example, the entire attachment area of the sub-label 2 is adhered to the outer surface of the tubular shrink label 1.

The method of adhering the attachment area of the sub-label 2 to the tubular shrink label 1 is not particularly limited. For example, (a) when the sub-label 2 and the tubular shrink label 1 are made of a solvent-adhesible material, which is adhered via a sticking agent layer 5 such as an adhesive or an adhesive as shown in the figure. (Not shown), and the like can be mentioned. As the pressure-sensitive adhesive, a conventionally known pressure-sensitive pressure-sensitive adhesive, a heat-sensitive pressure-sensitive adhesive, or the like can be used, and as the adhesive, a conventionally known solvent-volatile adhesive, an ultraviolet curable adhesive, or the like can be used.

The method for forming the adhesive layer 5 is not particularly limited, and typically, after applying the adhesive to the entire one surface of the sub-label 2, the concealing agent is applied except for the portion forming the adhesive layer. There is a way to do it. In the case of this forming method, the portion coated with the concealing agent becomes a non-adhesive surface. In addition, instead of the method of providing the concealing layer, a method of providing an adhesive only on the portion forming the adhesive layer 5 and not providing any other adhesive may be used. Hereinafter, the portion of the attached area that is adhered to the outer surface of the tubular shrink label 1 is referred to as an “adhesive portion” for convenience. In FIGS. 1 and 6, in order to make the range of the bonded portion easy to understand, dot-shaped hatching is provided in the range of the bonded portion for convenience. Also in other figures, the area where the dot-shaped hatching is applied indicates the bonded portion.

A perforation line 4 (sub-label perforation line) extending in the vertical direction is formed in the surface of the sub-label 2. When the adhesive layer 5 is interposed, the sub-label perforation line 4 is also formed so as to penetrate the adhesive layer 5. The sub-label sewing machine line of sight 4 is formed so as to overlap the shrink sewing machine line of sight 3 or at a position in the vicinity of the shrink sewing machine line of sight 3. When the sub-label sewing machine line is formed so as to overlap the shrink sewing machine line 3 (first shrink machine line 31), the shrink perforation line 3 and the sub-label sewing machine line 4 are formed in a plan view of the flat tubular shrink label 1. Each position of is matched. When the sub-label sewing machine line 4 is formed in the vicinity of the shrink machine line 3 (first shrink machine line 31), the shrink machine line 3 is laterally displaced by 3 mm or less from the shrink machine line 4 in the above plan view. Will be located.

The sub-label perforation line 4 may extend parallel to the vertical direction of the sub-label 2, or may be inclined in an acute angle (for example, 20 degrees or less) with respect to the vertical direction of the sub-label 2 in the vertical direction. It may be extended to. A part of the sub-label perforation line 4 inclined with respect to the vertical direction may be inclined, or the whole may be inclined. It should be noted that the sub-label perforation line 4 whose part is inclined is non-linear, and the sub-label perforation line 4 whose whole is inclined is linear. Preferably, the sub-label perforation line 4 extends in a straight line parallel to the vertical direction.

The sub-label perforation line 4 is composed of a set of a plurality of through-holes in which through-holes penetrating in the thickness direction of the sub-label 2 are intermittently formed. Therefore, the sub-label perforation line 4 has a non-penetrating portion (non-cutting portion) between adjacent through holes. The shape of one through hole of the sub-label perforation line 4 is generally substantially circular or linear, preferably linear. The length of one through hole of the sub-label perforation line 4 is not particularly limited, but is, for example, 0.2 mm to 1.5 mm, preferably 0.3 mm or more and less than 1.5 mm. The length of one non-penetrating portion of the sub-label perforation line 4 is not particularly limited, but is, for example, 0.2 mm to 1.5 mm.

The sub-label perforation line 4 may be formed from the first vertical edge to the second vertical edge of the sub-label 2, or may be formed from the first vertical edge to the vicinity of the second vertical edge. It may be formed from near the first edge in the vertical direction to the second edge in the vertical direction, near the first edge in the vertical direction, and near the second edge in the vertical direction. It may be formed. Near the first vertical edge of the sub-label 2 means a range 3 mm to 10 mm in the vertical direction from the first vertical edge, and near the second vertical edge means 3 mm in the vertical direction from the second edge. A range separated by 10 mm. Preferably, the sub-label perforation line 4 is formed from the first vertical edge of the sub-label 2 to the second vertical edge (formed over the entire vertical direction of the sub-label 2).

The sub-label perforation line 4 is provided so as to vertically traverse at least the attachment area of the sub-label 2. In the illustrated example, the sub-label perforation line 4 formed over the entire vertical direction of the sub-label 2 has a vertical first end portion 21 which is an independent region, an attachment region, and a vertical second end portion which is an independent region. It traverses 22.

The sub-label 2 may have one or more sub-label perforations 4 in the plane. When the sub-label 2 has two or more sub-label perforations 4, at least one of them is in the plane of the sub-label 2 so as to overlap the shrink perforation line 3 or to be located in the vicinity thereof. It is formed. In order to ensure that the sub-label 2 breaks along the sub-label perforation line 4 formed at or near the shrink perforation line 3, the sub-label 2 has one sub-label perforation line 4 It is preferable to have. The one sub-label sewing machine line 4 is provided, for example, so as to overlap the first shrink machine line 31 or the second shrink machine line 32. In the illustrated example, one sub-label sewing machine line of sight 4 is provided so as to overlap the first shrink sewing machine line of sight 31.

In particular, the sub-label sewing machine line 4 and the shrink machine line 3 preferably satisfy at least one relationship selected from the following (A) to (D), and one of (A) and (B). It is more preferable that the relationship and one of the relationships (C) and (D) are satisfied, and it is further preferable that all the relationships (A) to (D) are satisfied at the same time.

(A) Length of through hole of sub-label perforation line 4 <Length of through hole of first shrink perforation line 31;
(B) Length of through hole of sub-label perforation line 4 <Length of through hole of second shrink perforation line 32;
(C) (Length of through hole of secondary label sewing machine line 4 / length of non-penetrating portion of sub label sewing machine line 4) ≤ (length of through hole of first shrink machine line 31 / length of first shrink machine line 31) (Length of non-penetrating portion), however, in this case, (length of through hole of sub-label sewing machine line of sight 4 / length of non-penetrating part of sub-label sewing machine line of sight 4) <(through hole of first shrink sewing machine line of sight 31). Length / length of non-penetrating portion of first shrink perforation line 31);
(D) (Length of through hole of secondary label sewing machine line 4 / length of non-penetrating portion of sub label sewing machine line 4) ≤ (length of through hole of second shrink machine line 32 / length of second shrink machine line 32) (Length of non-penetrating part), however, in this case, (length of through hole of sub-label sewing machine line 4 / length of non-penetrating part of sub-label sewing machine line 4) <(through hole of second shrink sewing machine line 32) / Length of the non-penetrating portion of the second shrink sewing machine line of sight 32).

Generally, if a perforation line that can easily cut the label (for example, a perforation line with a long through hole length or a perforation line with a large ratio of the length of the through hole to the length of the non-penetration portion) is provided on the tubular shrink label. When the tubular shrink label is thermally shrunk, the through hole of the perforation line may be wide open and the non-penetrating portion may be connected to break the label. Therefore, it is not preferable to form a perforation line on the tubular shrink label that can cut the label too easily.

In this regard, in the present disclosure, since the sub-label 2 is attached so as to cover the first shrink sewing machine line of sight 31 and the second shrink sewing machine line of sight 32, the first and second shrink sewing machine line of sight 31, It is possible to suppress the opening of the through holes of 32. In particular, as shown in the illustrated example, the adhesive portion of the attachment area of the sub-label 2 covers the first shrink sewing machine line of sight 31 and the second shrink sewing machine line of sight 32, thereby particularly preventing the opening of the through hole of the shrink sewing machine line of sight 3. can. Therefore, a shrink sewing machine line of sight 3 satisfying any of the above relationships (A) to (D) (a shrink sewing machine line of sight 3 satisfying this relationship is a sewing machine line of sight that is easier to cut than the sub-label sewing machine line of sight 4). It can also be formed on the tubular shrink label 1. The cylindrical shrink label A with a sub-label having such a shrink perforation line 3 can be attached to the first shrink perforation line 31 or the second shrink perforation line 32 together with the sub-label sewing machine line 4 by pinching and pulling the sub-label 2 with a fingertip. Along the line, the tubular shrink 1 can be more easily divided into two.

<Long tubular shrink label original fabric>
FIG. 7 is a front view of the long tubular shrink label original fabric B. FIG. 8 is a perspective view of the long tubular shrink label original fabric B. In FIGS. 7 and 8, a part of the long tubular shrink label original fabric B is omitted. Further, the one-dot chain line in FIGS. 7 and 8 indicates the planned cutting line 6 (in other figures, the one-dot chain line indicates the planned cutting line 6). In addition, in this specification, "long" means a band shape whose length in the vertical direction is considerably larger than the length in the horizontal direction.

The long tubular shrink label original fabric B can cut out the tubular shrink label A with a sub-label by cutting laterally along the planned cutting line 6. That is, the long tubular shrink label original fabric B is a continuum in which a plurality of tubular shrink labels A with sub-labels are continuously connected by the planned cutting line 6, and is provided in a flatly folded manner. NS. Specifically, the long tubular shrink label original fabric B is a continuous body in which tubular shrink labels formed by forming a heat-shrinkable film in a tubular shape are continuously connected, and extends in the vertical direction and faces each other. The flat tubular shrink label continuum B1 folded at the pair of creases 19 and 19 and the sheet-shaped sub-label are continuously connected to each other, and the flat tubular shrink label continuum is formed. It has a long strip-shaped sub-label continuum B2 attached to the outer surface of B1.

Of the sub-label continuum B2, the peripheral zone 24 including the planned cutting line 6 is an independent region independent of the outer surface of the tubular shrink label continuum B1, and at least a part of the region excluding the independent region is the cylinder. It is adhered to the outer surface of the shrink label continuum B1. The peripheral zone region 24 including the planned cutting line 6 corresponds to a region in which the first vertical end portion 21 and the second vertical end portion 22 of the sub-label 2 are combined.

Further, in the present embodiment, the first end portion 23 in the lateral direction of the sub-label continuum B2 is also an independent region independent of the outer surface of the tubular shrink label continuum B1. Therefore, in the sub-label continuum B2, the peripheral zone region 24 including the planned cutting line 6 and the first lateral end portion 23 are set as independent regions, and the region excluding the independent region (this region is a cylinder with a sub-label). In the shape shrink label A, at least a part (corresponding to the attachment area of the sub label 2) is adhered to the outer surface of the tubular shrink label continuum B1. In the illustrated example, the entire region of the sub-label continuum B2 except the independent region is adhered to the outer surface of the tubular shrink label continuum B1.

Further, the cylindrical shrink label continuum B1 is formed with a shrink perforation line 3 extending in the vertical direction. For example, three shrink sewing machine lines 3 (first to third shrink machine lines 31, 32, 33) are formed, of which the first shrink machine line line 31 and the second shrink machine line line 32 are in the lateral direction. They are formed in close proximity to each other. The third shrink sewing machine line 33 is provided at a position that is not particularly related to the first shrink machine line 31 and the second shrink machine line 32 in the lateral direction. On the other hand, the sub-label continuum B2 is formed with a sub-label perforation line 4 extending in the vertical direction. The sub-label sewing machine line of sight 4 is provided so as to overlap with the first shrink sewing machine line of sight 31, for example.

The long tubular shrink label original fabric B can be manufactured, for example, as follows. With reference to FIG. 9, a long heat-shrinkable film 15 is pulled out from the roll product, and a perforation line 32 is continuously formed in the plane thereof in the vertical direction by using the perforation forming device 81. This sewing machine line of sight is the second shrink sewing machine line of sight 32. Examples of the perforation forming apparatus 81 include a roll cutter and a laser processing machine.

With the lateral direction (main heat shrinkage direction) of the heat shrinkable film 15 forming the perforation line 32 as the circumferential direction, the heat shrinkable film is rolled into a tubular shape, and the first side end portion is overlapped with the second side end portion. The tubular shrink label continuum B1 is obtained by forming the sealing portion 18 by adhering them together. The tubular shrink label continuum B1 is folded flat at a pair of creases.

On the other hand, as shown in FIG. 10, a long sub-label continuum B2 is pulled out from the roll product, and for example, a patch layer 5 is provided on the inner surface thereof. The adhesive layer 5 is provided except for the peripheral zone region 24 and the first lateral end portion 23 of the sub-label continuum B2. Therefore, the adhesive layer 5 is provided at a fixed interval in the vertical direction at the second end portion in the horizontal direction of the sub-label continuum B2. As the adhesive layer 5, for example, a solvent-volatile adhesive or the like can be used, and in this case, the adhesive coating machine 82 is used.

Instead of the sub-label continuum B2 in the illustrated example, a sub-label continuum with a release paper is provided on the inner surface in advance and a release paper is temporarily attached to the adhesive layer (not shown). May be used. The release paper is peeled off from the sub-label continuum with a release paper immediately before being attached to the tubular shrink label continuum, which will be described later, and the inner surface thereof is superposed on the tubular shrink label continuum.

As shown in FIG. 11, the inner surface of the sub-label continuum B2 is superposed on one surface of the tubular shrink label continuum B1 folded flat at the creases 19 and 19. At this time, the adhesive layer 5 is overlapped with the perforation line 32 (second shrink perforation line 32) of the tubular shrink label continuum B1 so that the sub-label continuum B2 is placed on one surface of the tubular shrink label continuum B1. Overlay on. The superposed sub-label continuum B2 is adhered to the tubular shrink label continuum B1 via the adhesive layer 5. That is, as shown in FIG. 12, the sub-label continuum B2 has the entire attached region as an adhesive portion, and is adhered to the tubular shrink label continuum B1 at the adhesive portion.

Finally, as shown in FIG. 12, the perforation forming apparatus 83 is used to form the perforation line 4 penetrating the sub-label continuum B2 and the tubular shrink label continuum B1 from the outer surface side of the sub-label continuum B2. do. The formation of the sewing machine line is to simultaneously form the sub-label sewing machine line 4, the first shrink machine line 31, and the third shrink machine line 33.

Specifically, the perforation line is carved by the perforation forming device 83 from the outer surface side of the sub-label continuum B2 corresponding to the position near the second shrink perforation line 32. At this time, the sub-label perforation line 4 extending in the vertical direction is formed in the plane of the sub-label continuum B2, and at the same time, the sewing machine has the same size as the through hole and the non-penetration portion of the sub-label perforation line 4. Lines of sight are formed on one side and the opposite side of the flat tubular shrink label continuum B1. The same perforation line as the sub-label perforation line 4 formed on one surface of the tubular shrink label continuum B1 is the first shrink perforation line 31 and is formed on the opposite surface of the tubular shrink label continuum B1. The same perforation line as the sub-label sewing machine line 4 is the third shrink perforation line 33. It should be noted that the sub-label continuum in which the sub-label perforation line 4 is formed on the tubular shrink label continuum B1 in which all the shrink perforation lines (for example, the first to third shrink perforation lines 31, 32, 33) are formed. B2 may be adhered to produce a long tubular shrink label original fabric B.

In this way, the long tubular shrink label original fabric B can be manufactured. The obtained flat long tubular shrink label raw fabric B is wound around a core material and used for storage and transportation in the form of a roll product, if necessary.

<Manufacturing method of a package with a tubular shrink label with a secondary label>
With reference to FIGS. 13 to 15, a method for manufacturing a package to which a tubular shrink label with a secondary label is attached, using a long tubular shrink label original fabric and a tubular shrink label with a secondary label, will be described. FIG. 13 is a front view of a package C obtained by heat-shrinking and mounting a tubular shrink label A with a sub-label on a container. FIG. 14 is an enlarged front view of the cap portion of the package C, and FIG. 15 is a top view (plan view of the cap portion viewed from one side in the vertical direction).

The method for manufacturing the package includes a step of preparing a long tubular shrink label raw fabric and a step of externally attaching a tubular shrink label with a sub-label cut out from the long tubular shrink label raw fabric. The present invention comprises a step of heat-shrinking the tubular shrink label with a sub-label externally attached to the adherend. For the long tubular shrink label original fabric, for example, the above-mentioned long tubular shrink label original fabric B can be used. The adherend is not particularly limited, but as shown in FIGS. 13 to 15, a container capable of accommodating the contents is typically mentioned.

With reference to FIGS. 13 to 15, the container 9 has a container body 91 and a cap portion 92 attached to the container body 91. From the bottom, the container body 91 has a body portion 911 having a storage space for storing the contents, a shoulder portion 912 connected to the body portion 911, and a neck portion connected to the shoulder portion 912 and having a flange portion 914 projecting outward. 913 and. The cap portion 92 is provided above the neck portion 913. If necessary, a design label displaying a product name or the like may be attached to the container body 91 and / or the cap portion 92, or a design may be directly printed (these designs are not shown). ..

The outer shape of the body portion 911 is not particularly limited as long as it is hollow and can store the contents inside. It may be a substantially polygonal columnar shape, a substantially frustum shape, a substantially frustum shape such as a substantially elliptical frustum shape, a substantially gourd shape, a substantially barrel shape, or the like.

The cap portion 92 is attached to the neck portion 913 in order to open and close the spout of the container body 91. The cap portion 92 of the illustrated example is detachably attached to the neck portion 913 by a screw action. Therefore, a male screw is formed on the outer surface of the neck portion 913 to which the cap portion 92 is attached. The cap portion 92 is, for example, internally fitted to the inside (spout) of the neck 913 and externally fitted to the outside of the neck 913, provided that the cap portion 92 is attached so as to close the spout. , The spout can be opened and closed via a hinge, etc. (Neither type is shown). The cap portion 92 is attached to the immediate vicinity of the flange portion 914. A cap portion 92 and a flange portion 914 (the cap portion 92 and the flange portion 914 are collectively referred to as a head) protrude around the neck portion 913. The material of the container body 91 and the cap portion 92 is not particularly limited, and examples thereof include glass, synthetic resin, metal, and pottery independently of each other.

The package C can be manufactured, for example, as follows. First, the long tubular shrink label original fabric B is prepared (the step of preparing the long tubular shrink label original fabric). Next, the cylindrical shrink label A with a sub-label cut out from the long tubular shrink label original fabric B is externally attached to the container 9 which is an adherend (step of externally attaching). Specifically, the tubular shrink label A with a sub-label is opened in a cylindrical shape (see FIG. 6), and is fitted onto the head of the container 9 (cap portion 92 including the flange portion 914). In the step of externally attaching the long tubular shrink label original fabric B, the tubular shrink label A cut out from the long tubular shrink label original fabric B may be externally attached to the container 9, and the long tubular shrink label original fabric B may be attached to the container. The tubular shrink label A may be externally attached to the container 9 by cutting the long tubular shrink label original fabric B along the planned cutting line 6 after the outer attachment to the container 9.

Next, the tubular shrink label A externally attached to the container 9 is heated to a heat shrinkage temperature and heat-shrinked (heat-shrinkable step). As a result, the tubular shrink label 1 is in close contact with the peripheral surface of the head, and the vertical first end portion 11 and the vertical second end portion 12 of the tubular shrink label 1 are the upper peripheral end portion and the lower surface of the head. It bends to the peripheral end and sticks to it. On the other hand, the independent region of the sub-label 2 projects away from the peripheral surface (peripheral surface of the head) of the container 9. In this way, the package C as shown in FIGS. 13 to 15 can be obtained.

<Effect>
According to the long tubular shrink label original fabric B of the present disclosure, the tubular shrink label 1 (cylindrical shrink label A with a sub label) to which the sub label 2 is attached can be continuously supplied. Further, in the tubular shrink label A with a sub-label of the present disclosure, since the sub-label 2 is attached to the tubular shrink label 1, the design and the like can be displayed not only on the tubular shrink label 1 but also on the sub-label 2. With the sub-label 2, the display area of the tubular shrink label 1 can be expanded.

In the present disclosure, in the tubular shrink label A with a sub-label, the vertical first end 21 and the vertical second end 22 of the sub-label 2 are independent regions independent of the tubular shrink label 1. , The vertical first end 21 and the vertical second end 22 of the sub-label 2 do not follow the cylindrical shrink label 1 which is thermally shrunk. Therefore, the vertical first end portion 21 and the vertical second end portion 22 of the sub-label 2 are flush with the attachment area of the sub-label 2 without being attracted to the bent portion of the tubular shrink label 1. The tubular shrink label 1 protrudes in the vertical direction from the upper bent portion and the lower bent portion.

Further, in the present disclosure, in the tubular shrink label A with a sub-label, since the first lateral end portion 23 of the sub-label 2 is an independent region independent of the tubular shrink label 1, the lateral direction of the sub-label 2 is set. The first end portion 23 does not follow the cylindrical shrink label 1 that shrinks heat. Therefore, the first lateral end portion 23 of the sub-label 2 is flush with the attachment area of the sub-label 2 without being attracted to the tubular shrink label 1, and is separated from the peripheral surface of the tubular shrink label 1. It will protrude.

As described above, in the package C of the present disclosure, since the sub-label 2 partially protrudes from the tubular shrink label 1 while maintaining the flatness, the display such as the design represented by the sub-label 2 is not easily distorted. , Has a favorable appearance.

Further, the cylindrical shrink label A with a sub-label of the present disclosure can be easily removed from the adherend by pulling the sub-label 2. Specifically, the first lateral end portion 23 of the sub-label 2 is pinched with a fingertip, and the sub-label 2 is pulled substantially parallel to the surface direction (the sub-label 2 is pulled in the direction of the white arrow in FIGS. 15 and 16). pull). A sub-label perforation line 4 is formed in the surface of the sub-label 2, and the sub-label 2 has at least tubular shrink labels 1 on both sides in the lateral direction sandwiching the sub-label perforation line 4 (first shrink perforation line 31). Since it is adhered to the outer surface of the sub-label, strain occurs in the vicinity of the sub-label perforation line 4, the sub-label 2 is broken substantially along the sub-label perforation line 4, and the sub-label 2 is divided into two. Further, since the tubular shrink label 1 has a shrink sewing machine line 3 (first shrink machine line 31 and / or a second shrink machine line 32) formed on or near the sub-label sewing machine line 4. , The impact due to the breakage of the sub-label 2 affects the vicinity of the shrink sewing machine line of sight 3, and the tubular shrink label 1 breaks substantially along the first shrink sewing machine line of sight 31 or the second shrink sewing machine line of sight 32 and is divided into two. NS.

16 and 17 are front views showing the process of removing the tubular shrink label with the sub-label, and show the state after the sub-label 2 and the tubular shrink label 1 are broken. After the division, the tubular shrink label A with the sub-label can be easily removed from the adherend (container 9).

In particular, when the sub-label perforation line 4 is formed over the entire vertical direction of the sub-label 2, the sub-label 2 can be more easily divided into two. Further, when the first shrink perforation line 31 and / or the second shrink perforation line 32 is formed over the entire vertical direction of the tubular shrink label 1, the bent portion (cylindrical shape) of the tubular shrink label 1 is formed. The vertical first end 11 and the vertical second end 12) of the shrink label 1 can also be easily divided. Further, since the tubular shrink label 1 is formed with the first shrink sewing machine line 31 overlapping the sub-label sewing machine line 4 and the second shrink perforation line 32 corresponding to the position near the sub-label sewing machine line 4, the tubular shrink label 1 is formed in a tubular shape. The shrink label 1 can be more reliably divided into two.

Hereinafter, another embodiment of the present disclosure will be described, but in the description thereof, configurations and effects different from those of the above-described embodiments will be mainly described, and for similar configurations and the like, terms or symbols are used as they are. The description of the configuration may be omitted.

[Second Embodiment]
FIG. 18 is a front view of the cylindrical shrink label with a sub-label according to the second embodiment. FIG. 19 is an enlarged cross-sectional view taken along the line XIX-XIX of FIG. In the first embodiment, the vertical first end 21, the vertical second end 22, and the horizontal first end 23 of the sub label 2 are independent regions, but in the second embodiment, the sub label 2 is sub. The vertical first end 21, the vertical second end 22, the horizontal first end 23, and the horizontal second end 25 of the label 2 are independent regions.

FIG. 20 shows a continuum of a cylindrical shrink label A with a sub-label (long tubular shrink label original fabric B) in which the second end portion 25 in the lateral direction is also an independent region. It is a front view of the long tubular shrink label original fabric. By cutting the long tubular shrink label original fabric B along the planned cutting line 6, the tubular shrink label A with a sub-label shown in FIG. 18 can be obtained. Also in the present embodiment, a package to which a tubular shrink label with a sub-label is attached can be manufactured by the same manufacturing method as described above.

[Third Embodiment]
FIG. 21 is a front view of the cylindrical shrink label with a sub-label according to the third embodiment. FIG. 22 is an enlarged cross-sectional view taken along the line XXII-XXII of FIG. In the first embodiment, the entire attachment area of the sub-label 2 is adhered to the outer surface of the tubular shrink label 1, but in the third embodiment, the attachment area is laterally sandwiched by the shrink perforation line 3. Only both sides are adhered to the outer surface of the tubular shrink label 1. The continuous body of the cylindrical shrink label A with the sub-label (long tubular shrink label original fabric B) is the continuous tubular shrink label A with the sub-label connected by the scheduled cutting line 6. Therefore, the drawing is omitted. Also in the present embodiment, a package to which a tubular shrink label with a sub-label is attached can be manufactured by the same manufacturing method as described above.

In the third embodiment, the attachment region of the sub-label 2 is non-adhesive in the shrink perforation line 3 and its lateral vicinity. The horizontally long 29W of this non-bonded portion (the horizontally long 29W of this portion is the distance between the two bonded portions as shown in FIG. 22) is not particularly limited, and can be used independently, for example, for example. It is 2 mm or more, preferably 3 mm or more.

[Fourth Embodiment]
FIG. 23 is a front view showing the tubular shrink label 1 constituting the tubular shrink label with the sub-label of the fourth embodiment. FIG. 24 is a front view showing a tubular shrink label 1 constituting another tubular shrink label with a sub-label according to the fourth embodiment. However, in any case, the tubular shrink label 1 is in a flatly folded state. Further, the sub-label 2 attached to the tubular shrink label 1 is represented by a two-dot chain line. In the fourth embodiment, a notch 7 is engraved in the plane of the tubular shrink label 1 so as to overlap the shrink perforation line of sight 3. Although the attached area is not shown by dot-shaped hatching in FIGS. 23 and 24, the attached area is not particularly limited, and for example, any of the first to third embodiments is used. It can be an attached area of.

In the portion where the linear cut 7 is superposed on the shrink perforation line 3 and engraved, the non-penetrating portion of the perforation line disappears. Therefore, it can be said that the cut 7 has a length that is several times to several tens of times larger than the length of the through hole at the perforation line. The cut 7 can be formed at an arbitrary position of the shrink sewing machine line of sight 3. By forming the cut 7, the tubular shrink label 1 is likely to break along the shrink perforation line 3. It is preferable that the cut 7 is formed in at least one of the first shrink sewing machine line 31 and the second shrink machine line 32.

Specifically, the tubular shrink label 1 shown in FIG. 23 is formed with a linear cut 7 superimposed on the middle portion in the vertical direction of the first shrink perforation line 31. The tubular shrink label 1 shown in FIG. 24 is formed by overlapping cuts 7 on the first vertical end and the second vertical end of the first shrink perforation line 31. The tubular shrink label 1 shown in FIG. 24 has a bent portion (a first end portion 11 in the vertical direction and a second portion in the vertical direction of the tubular shrink label 1) generated when the tubular shrink label A with a sub-label is attached to an adherend. A cut 7 is formed at a position corresponding to the end portion 12).

Although not particularly shown, the cuts 7 may be formed so as to overlap each other at the first vertical end portion, the second vertical end portion, and the middle portion in the vertical direction of the first shrink perforation line 31. Further, instead of the first shrink perforation line 31, a cut 7 is formed at at least one selected from the vertical first end portion, the vertical direction second end portion, and the vertical direction midway portion of the second shrink perforation line 32. It may be (not shown). Further, the cut 7 may be formed so as to overlap both the first shrink sewing machine line 31 and the second shrink machine line 32 (not shown).

In the case of the method of forming the sub-label sewing machine line 4 and the first shrink machine line 31 at the same time as described above (see FIG. 12 and the like), the cut is formed in the first shrink machine line 31 without forming a cut in the sub-label sewing machine line 4. Is difficult to form. Therefore, when the manufacturing method for simultaneously forming the sub-label sewing machine line 4 and the first shrink machine line 31 is performed, it is preferable to form the cut 7 in the second shrink machine line 32. Also in the present embodiment, a package to which a tubular shrink label with a sub-label is attached can be manufactured by the same manufacturing method as described above.

With reference to FIGS. 25 and 26, for example, a temporary fixing portion 71 is provided at a point near the first edge of the lateral first end portion 23 of the sub-label continuum B2. The temporary fixing portions 71 are provided in spots in the vertical direction at regular intervals (vertically long tubular shrink labels A with sub-labels continuously connected), for example. The temporary fixing portion 71 is not particularly limited as long as it can adhere the sub-label 2 to the outer surface of the tubular shrink label 1 with a weak adhesive force that can be peeled off with a slight force, and for example, an adhesive or the like can be used. Can be mentioned. Also in the present embodiment, the same manufacturing method as described above is carried out, and by separating the tubular shrink label 1 and the sub-label 2 temporarily fastened by the temporary fixing portion 71, the tubular shrink label with the sub-label can be obtained. It is possible to manufacture the mounted package.
