Description

Long tubular shrink label material, manufacturing method of packaging body, and tubular shrink label with sub-label

The present disclosure relates to a long tubular shrink label material, a method for manufacturing a package, and a tubular shrink label with a sub label.

A tubular shrink label is known in which a heat-shrinkable film is formed into a tubular shape. Such a tubular shrink label is used by being attached by heat shrinkage to an appropriate position of an adherend such as a container. For example, in order to protect the cap portion of a container containing beverages, seasonings and the like, and to ensure that the cap portion is unopened, a tubular shrink label is attached around the cap portion. Among the cylindrical shrink labels, those attached to the cap portion for the above purpose are also called cap seals.

Regarding such a tubular shrink label, a tubular shrink label to which a sub label is attached is known in order to expand the display area. For example, in Patent Document 1 (Japanese Patent Laid-Open No. 8-137398), a heat-shrinkable tubular main body (cylindrical shrink label) is attached to the outer surface with a flag (sub-label) end portion with a flag. A tube label (cylindrical shrink label with sub-label) is disclosed.

However, the tube label with flag of Patent Document 1 (cylindrical shrink label with sub-label) is manufactured by adhering one flag to one tubular body. Therefore, there is a problem that a plurality of tube labels with flags cannot be continuously supplied to the mounting machine. Further, in the flagged tube label of Patent Document 1, since the top end edge and the lower end edge of the tubular main body portion wrap around the upper and lower surfaces of the cap portion after being attached to the cap portion, the tubular main body portion is capped. There is also a problem that it is difficult to remove from the section.

[First Embodiment]
<Cylindrical shrink label with sub-label>
The tubular 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 into a tubular shape, and a sheet-like sub-label 2 attached to the outer surface of the tubular shrink label 1. Have. As shown in FIGS. 1 to 5, the tubular shrink label A with a sub-label before being heat-shrinkably attached to an adherend such as a container usually extends in the longitudinal direction of the tubular shrink label 1 and faces each other. The pair of

fold lines

19 and 19 are flatly folded. When the tubular shrink label A with the sub-label is attached to the adherend, the tubular shrink label 1 is three-dimensionally opened (for example, a substantially cylindrical three-dimensional shape) as shown in FIG. In the column of <Cylindrical shrink label with sub-label>, the cylindrical shrink label 1 indicates a state before being heat-shrinked (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 continuous body 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 anti form. By appropriately cutting this long tubular shrink label raw material along a 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-shaped flexible heat-shrinkable film formed in a tubular shape. The heat shrinkable film is a film that shrinks in the heat shrinking direction when heated to the heat shrinking temperature. The heat shrinkage temperature is, for example, 60°C to 120°C, preferably 80°C to 110°C.

As the heat-shrinkable film, heat-shrinkable synthetic resin film, non-woven fabric, foamed resin film, laminated film of these, and the like can be mentioned. The laminated film may be a laminate of a layer having no heat shrinkability and a layer having heat shrinkability provided that the entire laminate has heat shrinkability. The heat-shrinkable film is preferably a synthetic resin film or a synthetic resin laminated film, more preferably a synthetic resin film or a synthetic resin laminated film that does not include a fiber-containing sheet such as a nonwoven fabric (metal vapor deposition is applied to this laminated film. Films having layers are also included).

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

As the heat-shrinkable film, a film containing a polystyrene-based resin is preferable because it is relatively soft and easy to tear along the perforation line, and 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 is, for example, 8 μm to 100 μm, and particularly about 20 μm to 80 μm.

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

The heat shrinkage rate of the heat shrinkable film in the first direction (heat shrinkage direction) is not particularly limited, but is preferably 20% or more, more preferably 30% or more, and further preferably 40% or more. .. The larger the heat shrinkage in the first direction is, the more preferable it is. However, there is a limit in itself, and the heat shrinkage in the first direction is theoretically less than 100%. When the heat-shrinkable film is a film that thermally changes 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 thermal elongation.

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

The film is rolled into a tubular shape so that the first direction of the heat-shrinkable film (main heat-shrinking direction) is the circumferential direction, and the first side end of the heat-shrinkable film is superposed on the second side end. The seal portion 18 is formed by bonding. Thereby, the tubular shrink label 1 is configured. The seal portion 18 extends in a strip shape in the vertical direction of the tubular shrink label 1. The method for adhering the first side end and the second side end is not particularly limited, and examples thereof include welding using a solvent, adhering using an adhesive, and heat welding. The circumference of the cylindrical shrink label 1 is, for example, more than 1 times the maximum circumference of the attachment site of the adherend and not more than 1.5 times and preferably not more than 1.01 times to 1 times the same. 3 times, and more preferably, the same x 1.02 times to the same x 1.15 times.

The heat-shrinkable film may be provided with a design print layer that displays desired characters and patterns, if necessary (the design print layer is not shown). When the design printing layer is provided on the back surface side of the heat-shrinkable film (the back surface of the heat-shrinkable film becomes the inner surface when it becomes the tubular shrink label 1), a transparent heat-shrinkable film is used. To be In the present specification, transparent (colorless transparent or colored transparent) means that the total light transmittance is 70% or more, preferably 80% or more, and more preferably 90% or more. However, the total light transmittance is a value measured by a measuring method in accordance with JIS K7361 (Plastic-transparent material total light transmittance test method). Furthermore, the heat-shrinkable film may be provided with an optional functional layer, if necessary. Examples of the functional layer include a surface protective layer and a slip layer. The design print layer, the functional layer, and the like are conventionally known as constituent elements of the tubular shrink label 1, and known structures can be adopted in the present disclosure.

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

The shrink perforation line 3 may extend parallel to the longitudinal 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 longitudinal direction of the tubular shrink label 1. However, it may be extended in the vertical direction. The shrink perforation line 3 that is inclined with respect to the longitudinal direction may be partially inclined or may be entirely inclined. In addition, the shrink perforation line 3 in which a part is inclined is non-linear, and the shrink perforation line 3 in which the 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 a line (collection of a plurality of through holes) in which through holes that penetrate in the thickness direction of the film are intermittently formed. Therefore, the shrink perforation line 3 has a non-penetrating portion (non-cutting portion) between adjacent through holes. That is, the shrink perforation line 3 is a line in which through holes and non-penetrating portions are alternately arranged. The shape of one through hole is generally a substantially circular shape or a linear shape, and preferably a linear shape. 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-penetrating 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 surface of the tubular shrink label 1, and preferably a plurality (two or more) are formed. In the illustrated example, three shrink perforation lines 3 are formed on the tubular shrink label 1. Hereinafter, in order to distinguish these shrink perforation lines in terms of terms, they are referred to as “first shrink perforation line 31,” “second shrink perforation line 32,” and “third shrink perforation line 33,” collectively, “shrink perforation line”. 3”.

It is preferable that the first shrink perforation line 31 and the second shrink perforation line 32 are arranged at positions close to each other in the lateral direction. That is, in the plane of the cylindrical shrink label 1 in which the perforation line (first shrink perforation line 31) extending in the vertical direction is formed, the second line is formed at a position near the perforation line (first shrink perforation line 31). It is preferable that a perforation line (second shrink perforation line 32) is formed. In the vicinity, the two shrink perforations 3 (the first shrink perforation line 31 and the second shrink perforation line 32) do not overlap with each other, and one shrink perforation line 3 (first shrink perforation line 31) is used as a reference. It means that one shrink perforation line 3 (second shrink perforation line 32) is located laterally (either the first side or the second side) away from the reference by a distance of 3 mm or less.

The third shrink perforation line 33 is not particularly related to the first shrink perforation line 31 and the second shrink perforation line 32 in the lateral direction, and is formed apart from these shrink perforation line 3 in the lateral direction. Has been done. When four or more shrink perforation lines 3 are formed (not shown), as for the shrink perforation lines other than the first to third shrink

perforation lines

31, 32, 33, one shrink perforation line selected from them is selected. It may be arranged at a position in the vicinity of the line of sight, or may be arranged at a position having no particular relation in the lateral direction.

The shrink perforation lines 3 may be formed from a first longitudinal edge to a second longitudinal edge of the tubular shrink label 1 that are spaced apart in the longitudinal direction, and may extend from the first longitudinal edge to the second longitudinal edge. It may be formed over the vicinity thereof, may be formed over the second longitudinal edge from near the first longitudinal edge, and may be formed near the first longitudinal edge near the second longitudinal edge. It may be formed over. Preferably, the first shrink perforation line 31 is formed from the first longitudinal edge to the second longitudinal edge of the tubular shrink label 1. A perforation line formed over the entire length in the vertical direction is particularly referred to as "all vertical perforation".

The above-mentioned first longitudinal edge is the one opening tubular edge of the tubular shrink label 1, and the second longitudinal edge is the other opening tubular edge. The length between the first longitudinal edge and the second longitudinal edge corresponds to the longitudinal length of the tubular shrink label 1. The vicinity of the first longitudinal edge means a range separated from the first edge by 3 mm to 10 mm in the longitudinal direction, and the vicinity of the second longitudinal edge means a distance of 3 mm to 10 mm in the longitudinal direction from the second longitudinal edge. A range.

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

shrink perforation lines

31 and 32, or they may be other than all the vertical perforations.

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

Sub-label 2 is made of a flexible film. Preferably, the sub-label 2 is a film that does not substantially shrink in the lateral direction, and more preferably a film that does not substantially shrink in the lateral direction. The term “not substantially heat-shrink” means that the heat-shrinkable film (cylindrical shrink label 1) hardly heat-shrinks. Expressed in terms of heat shrinkage, the film that does not substantially shrink (sub label 2) has a heat shrinkage of 0 to 5% in the transverse direction, and preferably has a heat shrinkage of 0 in both the transverse and longitudinal 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; multiple different or similar resin layers are laminated. A resin laminated film; a nonwoven fabric; a foamed resin film; a laminated film in which two or more kinds selected from these are laminated can be used. Examples of the resin material for the synthetic resin film or the resin laminated film include those exemplified for the heat-shrinkable film. The thickness of the film forming 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 forming 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 comprises synthetic paper, the sub-label 2 will be opaque. Since the synthetic resin film is normally transparent, the sub-label 2 becomes opaque by performing opaque printing such as white solid printing or silver solid printing. The film forming the sub-label 2 may be provided with a design printing layer on the outer surface side and/or the inner surface side thereof, which displays desired characters, pictures, etc., if necessary. (Not shown).

The sub label 2 is attached to the outer surface of the cylindrical shrink label 1 in the attachment area. When the vertical length of the cylindrical shrink label 1 and the vertical length of the sub label 2 are equal, the vertical first edge of the sub label 2 is viewed from the front (direct view from the direction along the vertical direction of the plane including the vertical direction and the horizontal direction). In, the vertical first edge of the tubular shrink label 1 is matched, and the vertical second edge of the sub label 2 is matched with the vertical second edge of the tubular shrink label 1 in a front view. preferable. The vertical first edge and the vertical second edge of the sub label 2 are edges that are opposed to each other in the vertical direction, and the length between the vertical first edge and the second edge is the vertical length of the sub label 2. Equivalent to. The vertical label of the tubular shrink label 1 and the vertical length of the sub label 2 are equal, and the sub label 2 attached so that each vertical first edge and each vertical second edge are the same. Do not extend outside 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 enlarging the display area by attaching another sub label 2 to the tubular shrink label 1 becomes relatively small. From this viewpoint, the horizontal length of the sub label 2 is, for example, the horizontal length of the tubular shrink label 1 folded in a flat shape×1/5 or more, and 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 on the outside of one fold 19 of the flattened tubular shrink label 1. The sub label 2 protrudes and the handling becomes bad. From this viewpoint, the lateral length of the sub label 2 is, for example, equal to or less than the lateral length of the tubular shrink label 1 folded flat (or less than the lateral length of the tubular shrink label 1 folded flat), and preferably the lateral length x It is 4/5 or less. With a specific numerical value, the lateral 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 length in the horizontal direction between the pair of

folds

19 and 19, and this horizontal length is half the circumferential 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 tubular 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.

In the sub-label 2 arranged as described above, the vertical first end 21, the vertical second end 22 and the horizontal first end 23 are independent regions independent of the tubular shrink label 1. Is. The sub-label 2 is an attachment area attached to the outer surface of the tubular shrink label 1 except the independent area. The attachment area of the sub label 2 covers at least the first shrink perforation line 31 and preferably the first shrink perforation line 31 and the second shrink perforation 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 cylindrical shrink label 1. The entire attachment area may be adhered to the outer surface of the tubular shrink label 1, or a part of the attachment area may be non-adhered to the outer surface of the tubular shrink label 1. The “non-adhesive portion” in the attachment area includes, for example, a portion other than the outer edge portion of the top area when the outer edge portion of the attachment area is attached to the outer surface. That is, the “non-adhesive portion” in the attachment area has no or extremely low freedom of movement with respect to the outer surface of the tubular shrink label 1. Further, the independent region is a region which is not entirely adhered 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. The term "adhesion" means that the sub-label 2 is bonded to the cylindrical shrink label 1 by physical or/and chemical force, and the term "non-adhesion" means that the sub-label 2 does not have the above-mentioned bonding. ..

The vertical lengths 21H and 22H of the vertical first end 21 and the vertical second end 22 of the sub label 2, which are independent regions, are the same when the tubular shrink label with a sub label A is attached to the adherend. It is preferable that the length is equal to or more than the length corresponding to the bent portion of the striped shrink label 1. With specific numerical values, the vertical lengths 21H and 22H of the vertical first end 21 and the vertical second end 22 of the sub-label 2 are, for example, 2 mm or more, and preferably 5 mm or more, independently of each other. is there. On the other hand, if the vertical lengths 21H and 22H are too large, the vertical length of the attachment area becomes relatively small, so that the vertical first end portions 21 and the vertical second end portions 22 of the sub-label 2 have a vertical length 21H, 22H is independently 20 mm or less, preferably 10 mm or less.

The horizontal length 23W of the horizontal first end 23 of the sub-label 2 which is an independent area is not particularly limited. However, if the horizontal length 23W is too small, it becomes difficult to pinch the lateral first end 23 of the sub label 2 when the tubular shrink label with a sub label A is attached to the adherend, and if it is too large, the horizontal length 23W is relatively large. The horizontal length of the attachment area becomes too small. From this viewpoint, when the lateral length of the sub label 2 is 15 mm to 100 mm as described above, the lateral length 23W of the lateral first end 23 of the sub label 2 is 10 mm to 90 mm, preferably 20 mm to 80 mm. Is. It should be noted that the vertical length of the attached area=the vertical length of the sub label 2−(the vertical length 21H of the vertical first end 21 of the sub label 2+the vertical length 22H of the vertical second end 22 of the sub label 2), the horizontal length of the attached area=the sub Horizontal length of label 2−horizontal length 23W of the horizontal first end portion 23 of the sub label 2.

The attachment area of the sub-label 2 may be wholly adhered to the tubular shrink label 1, and the both lateral ends sandwiching at least one shrink perforation line 3 (first shrink perforation line 31) are tubular. It may be adhered to the shrink label 1, or 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 cylindrical 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-adhesive material as shown in FIG. Can be adhered using a solvent (not shown). A conventionally known pressure-sensitive adhesive or a heat-sensitive adhesive can be used as the pressure-sensitive adhesive, and a conventionally-known solvent-volatile type adhesive or an ultraviolet-curable adhesive can be used as the adhesive.

The method for forming the adhesive layer 5 is not particularly limited, and typically, the adhesive is applied to the entire one surface of the sub-label 2, and then the masking agent is applied except for the portion where the adhesive layer is formed. There is a method of doing. In the case of this forming method, the portion coated with the masking agent becomes the non-adhesive surface. Instead of providing the concealing layer, a method may be used in which the pressure-sensitive adhesive is provided only on the portion where the adhesive layer 5 is formed and no pressure-sensitive adhesive is provided on other portions. Hereinafter, of the attachment area, a portion 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 it easy to understand the range of the adhesive portion, the area of the adhesive portion is hatched in a dot shape for convenience. In other figures as well, the area hatched in a dot pattern 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 formed so as to penetrate the adhesive layer 5 as well. The sub-label perforation line 4 is formed so as to overlap the shrink perforation line 3 or in the vicinity of the shrink perforation line 3. When the sub-label perforation line is formed so as to overlap the shrink perforation line 3 (first shrink perforation line 31), in the plan view of the flat tubular shrink label 1, the shrink perforation line 3 and the sub-label perforation line 4 are The positions of are the same. When the sub-label perforation line 4 is formed near the shrink perforation line 3 (first shrink perforation line 31), the shrink perforation line 3 is laterally displaced from the shrink perforation line 4 by 3 mm or less in the 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 while being vertical. It may be extended to. The sub-label perforation line 4 tilted with respect to the vertical direction may be partly tilted, or may be tilted entirely. The sub-label perforation line 4 in which a part is inclined is non-linear, and the sub-label perforation line 4 in which the 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 plurality of through-holes in which the 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 a substantially circular shape or a linear shape, preferably a linear shape. 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 longitudinal edge to the second longitudinal edge of the sub label 2, or may be formed from the first longitudinal edge to near the second longitudinal edge. It may be formed from the vicinity of the first longitudinal edge to the second longitudinal edge, such as near the first longitudinal edge, BR> and near the second longitudinal edge. It may be formed. The vicinity of the first vertical edge of the sub label 2 refers to a range separated from the first vertical edge by 3 mm to 10 mm in the vertical direction, and the vicinity of the second vertical edge means 3 mm in the vertical direction from the second edge. It refers to a range separated by 10 mm. Preferably, the sub-label perforation line 4 is formed from the first longitudinal edge to the second longitudinal edge of the sub-label 2 (formed over the entire longitudinal length of the sub-label 2).

The secondary label perforation line 4 is provided so as to cross at least the attachment area of the secondary label 2. In the illustrated example, the sub label perforation line 4 formed over the entire length of the sub label 2 in the vertical direction includes a vertical first end portion 21 which is an independent area, a vertical second end portion which is an attachment area and an independent area. 22 is cut vertically.

The sub-label 2 may have one or more sub-label perforation lines 4 in the plane. When the sub-label 2 has two or more sub-label perforation lines 4, at least one of the sub-labels is in the plane of the sub-label 2 so as to overlap the shrink perforation line 3 or be positioned in the vicinity thereof. It is formed. In order to surely break the sub-label 2 along the sub-label perforation line 4 formed at a position overlapping with or near the shrink perforation line 3, the sub-label 2 includes one sub-label perforation line 4. It is preferable to have For example, the one sub-label perforation line 4 is provided so as to overlap the first shrink perforation line 31 or the second shrink perforation line 32. In the illustrated example, one sub-label perforation line 4 is provided so as to overlap the first shrink perforation line 31.

In particular, the sub-label perforation line 4 and the shrink perforation line 3 preferably satisfy at least one relationship selected from the following (A) to (D), and either 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 simultaneously satisfied.

(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 sub-label perforation line 4/length of non-penetrating portion of sub-label perforation line 4)≦(length of through-hole of first shrink perforation line 31/first shrink perforation line 31) (The length of the non-penetrating portion of the sub-label perforation line 4/the length of the non-penetrating portion of the sub-label perforation line 4)<(the through-hole of the first shrink perforation line 31) Length/the length of the non-penetrating portion of the first shrink perforation line 31));
(D) (length of through-hole of sub-label perforation line 4/length of non-penetrating portion of sub-label perforation line 4)≦(length of through-hole of second shrink perforation line 32/second shrink perforation line 32 (Length of non-penetrating portion of sub-label perforation line 4/length of non-penetrating portion of sub-label perforation line 4)<(through-hole of second shrink perforation line 32) Length/the length of the non-penetrating portion of the second shrink perforation line 32).

In general, when a perforation line (for example, a perforation line with a long through hole or a perforation line with a large ratio of the length of the through hole to the length of the non-penetrating part) that can easily cut the label 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 perforations on the tubular shrink label so that the label can be cut too easily.

In this respect, in the present disclosure, since the sub-label 2 is attached so as to cover the first shrink perforation line 31 and the second shrink perforation line 32, the first and second shrink perforation lines 31, The opening of the through hole 32 can be suppressed. Particularly, as in the illustrated example, the adhesive portion of the attachment area of the sub-label 2 covers the first shrink perforation line 31 and the second shrink perforation line 32, so that the opening of the through hole of the shrink perforation line 3 is particularly prevented. it can. Therefore, a shrink perforation line 3 that satisfies any of the above relationships (A) to (D) (the shrink perforation line 3 that satisfies this relationship is a perforation line that is easier to cut than the sub-label perforation line 4). It can also be formed on the tubular shrink label 1. The tubular shrink label A with a sub label having such a shrink perforation line 3 is attached to the first label perforation line 31 or the second perforation line 32 along with the sub label perforation line 4 by grasping and pulling the sub label 2 with a fingertip. The tubular shrink 1 can be more easily divided into two along it.

<Long tubular shrink label stock>
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. 7 and 8, a part of the long tubular shrink label original fabric B is omitted. The dashed-dotted line in FIGS. 7 and 8 indicates the planned cutting line 6 (in other figures, the dashed-dotted line also indicates the planned cutting line 6). In addition, in this specification, "long length" means a strip shape whose length in the vertical direction is considerably larger than the length in the horizontal direction.

The long tubular shrink label material B is capable of cutting out the tubular shrink label A with the sub-label by cutting it laterally at the planned cutting line 6. That is, the long tubular shrink label original fabric B is a continuous body in which a plurality of sub-labeled tubular shrink labels A are continuously connected at the planned cutting line 6, and is provided in a flat folded state. It Specifically, the long tubular shrink label original fabric B is a continuous body in which tubular shrink labels each having a heat-shrinkable film formed in a tubular shape are continuously connected, and extend in the longitudinal direction and face each other. A flat tubular shrink label continuous body B1 folded at a pair of

folds

19 and 19 and a sheet-shaped sub-label are continuously connected, and the flat tubular shrink label continuous body is provided. And a long strip-shaped sub-label continuum B2 attached to the outer surface of B1.

In the sub label continuum B2, the peripheral zone region 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 continuous shrink label continuous body B1. The peripheral band region 24 including the planned cutting line 6 corresponds to a region in which the vertical first end 21 and the vertical second end 22 of the sub-label 2 are combined.

Further, in the present embodiment, the lateral first end 23 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 area 24 including the planned cutting line 6 and the lateral first end 23 are independent areas, and the area excluding the independent area (this area is a cylinder with a sub-label). In the cylindrical shrink label A, at least a part of (corresponding to the attachment area of the sub label 2) is bonded to the outer surface of the cylindrical shrink label continuous body B1. In the illustrated example, the entire area of the sub label continuous body B2 excluding the independent area is adhered to the outer surface of the tubular shrink label continuous body B1.

Also, the tubular shrink label continuum B1 is formed with a shrink perforation line 3 extending in the vertical direction. For example, three shrink perforation lines 3 (first to third shrink

perforation lines

31, 32, 33) are formed, of which the first shrink perforation line 31 and the second shrink perforation line 32 are in the lateral direction. They are formed in positions close to each other. The third shrink perforation line 33 is provided at a position not particularly related to the first shrink perforation line 31 and the second shrink perforation line 32 in the lateral direction. On the other hand, a sub label perforation line 4 extending in the vertical direction is formed on the sub label continuum B2. The sub-label perforation line 4 is provided so as to overlap the first shrink perforation line 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 drawn out from a roll product, and perforation lines 32 are continuously formed in the plane in the longitudinal direction by using a perforation forming device 81. This perforation line is the second shrink perforation line 32. Examples of the perforation forming device 81 include a roll cutter and a laser processing machine.

The heat-shrinkable film 15 having the perforation lines 32 is rolled into a tubular shape with the lateral direction (main heat-shrinking direction) as the circumferential direction, and the first side end is overlapped with the second side end. The tubular shrink label continuum B1 is obtained by bonding and forming the seal portion 18. The tubular shrink label continuum B1 is flatly folded at a pair of folds.

On the other hand, as shown in FIG. 10, a long sub label continuum B2 is pulled out from the roll product, and the adhesive layer 5 is provided on the inner surface thereof, for example. The adhesive layer 5 is provided excluding the circumferential zone 24 and the lateral first end 23 of the sub label continuum B2. Therefore, the adhesive layer 5 is provided at a constant interval in the vertical direction at the second lateral end 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 applicator 82 is used.

It should be noted that instead of the sub-label continuum B2 in the illustrated example, a sub-label continuum with release paper (not shown) in which an adhesive layer is provided in advance on the inner surface and release paper is temporarily attached to the adhesive layer May be used. In such a sub label continuous body with release paper, the release paper is peeled off immediately before being attached to the tubular shrink label continuous body described later, and the inner surface thereof is superposed on the tubular shrink label continuous body.

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

folds

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 attached to one surface of the tubular shrink label continuum B1. Overlaid on. The overlapped sub label continuous body B2 is bonded to the tubular shrink label continuous body B1 via the adhesive layer 5. That is, as shown in FIG. 12, in the sub label continuum B2, the entire attachment region serves as an adhesive portion, and the adhesive portion adheres to the tubular shrink label continuum B1.

Lastly, as shown in FIG. 12, using the perforation forming device 83, the perforation line 4 penetrating the sub label continuous body B2 and the tubular shrink label continuous body B1 from the outer surface side of the sub label continuous body B2 is formed. To do. The perforation line is formed by simultaneously forming the sub-label perforation line 4, the first shrink perforation line 31, and the third shrink perforation line 33.

Specifically, the perforation line is engraved by the perforation forming device 83 from the outer surface side of the sub label continuum B2 in a position near the second shrink perforation line 32. At this time, a sub label perforation line 4 extending in the vertical direction is formed in the surface of the sub label continuum B2, and at the same time, a perforation hole and a non-penetration part of the sub label perforation line 4 are machined in the same size. Eyes are formed on one surface of the flat tubular shrink label continuous body B1 and on the opposite surface thereof, respectively. 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, which is formed on the opposite surface of the tubular shrink label continuum B1. The same perforation line as the sub-label perforation 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 manufacture the 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 original fabric B is wound around a core material as needed and provided for storage and transportation in the form of a roll product.

<Method of manufacturing package with tubular shrink label with sub-label attached>
A method of manufacturing a package in which a tubular shrink label with a sub-label is attached, which uses the long tubular shrink label original fabric and the tubular shrink label with a sub-label, will be described with reference to FIGS. 13 to 15. FIG. 13 is a front view of a package C obtained by thermally shrink-fitting the tubular shrink label A with a sub-label in a container. 14 is an enlarged front view of the cap portion of the package C, and FIG. 15 is a top view thereof (a plan view of the cap portion viewed from one side in the vertical direction).

The manufacturing method of the packaging body, a step of preparing a long tubular shrink label raw material, a step of externally adhering a tubular shrink label with a sub label cut out from the long tubular shrink label raw material, And a step of heat-shrinking the tubular shrink label with the sub label externally attached to the adherend. As the long tubular shrink label raw material, for example, the long tubular shrink label raw material B described above 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. The container main body 91 includes, in order from the bottom, a body portion 911 having a storage space for storing 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 protruding outward. 913 and. The cap portion 92 is provided above the neck portion 913. The container body 91 and/or the cap portion 92 may be attached with a design label indicating a product name or the like, or the 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 so that the contents can be stored therein, and in addition to the substantially cylindrical shape as shown in the drawing, although not shown, it is a substantially elliptic cylinder shape, a substantially square pillar shape, a substantially triangular pillar shape. The shape may be a substantially polygonal column, a truncated cone shape, a truncated cone shape such as a truncated elliptical cone, a substantially gourd shape, or a substantially daruma shape.

The cap part 92 is attached to the neck part 913 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, a type that is internally fitted to the inside of the neck portion 913 (a spout portion), or a type that is externally fitted to the outside of the neck portion 913, provided that the cap portion 92 is attached so as to be able to close the spout portion. Alternatively, the spout may be opened and closed via a hinge (both types are not shown). The cap portion 92 is attached up to the 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 portion) project 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, independently of each other, glass, synthetic resin, metal, pottery, and the like.

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

Next, the cylindrical shrink label A externally attached to the container 9 is heated to the heat shrink temperature to be heat shrunk (heat shrink step). As a result, the tubular shrink label 1 is brought into close contact with the peripheral surface of the head, and the first longitudinal end 11 and the second longitudinal end 12 of the tubular shrink label 1 are attached to the upper peripheral edge and the lower surface of the head. Bends and adheres to the peripheral edge. On the other hand, the independent region of the sub label 2 projects away from the peripheral surface of the container 9 (the peripheral surface of the head). In this way, the package C as shown in FIGS. 13 to 15 is obtained.

<Effect>
According to the long tubular shrink label original fabric B of the present disclosure, the tubular shrink label 1 to which the sub label 2 is attached (the tubular shrink label A with the sub label) can be continuously supplied. In the tubular shrink label A with a sub label of the present disclosure, the sub label 2 is attached to the tubular shrink label 1, so that not only the tubular shrink label 1 but also the sub label 2 can display a design or the like. The display area of the tubular shrink label 1 can be increased by the sub label 2.

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 portion 21 and the vertical second end portion 22 of the sub label 2 do not follow the tubular shrink label 1 that is thermally contracted. Therefore, the vertical first end 21 and the vertical second end 22 of the sub label 2 are flush with the attachment area of the sub label 2 without being drawn to the bent portion of the tubular shrink label 1. The cylindrical shrink label 1 is projected 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 the sub-label, since the lateral first end 23 of the sub-label 2 is an independent region independent of the tubular shrink label 1, the sub-label 2 has the lateral direction. The first end portion 23 does not follow the tubular shrink label 1 that is thermally contracted. 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 drawn to the tubular shrink label 1, and is separated from the peripheral surface of the tubular shrink label 1. It comes to protrude.

As described above, in the package C of the present disclosure, since the sub label 2 partially projects from the tubular shrink label 1 while keeping the flat shape, the display such as the design shown on the sub label 2 is less likely to be distorted. , With a pleasing appearance.

Further, the tubular 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 lateral first end 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 shown 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 the tubular shrink label 1 on both lateral sides 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 is generated in the vicinity of the sub label perforation line 4, and the sub label 2 is broken substantially along the sub label perforation line 4 and divided into two. Further, the tubular shrink label 1 has the shrink perforation line 3 (the first shrink perforation line 31 and/or the second shrink perforation line 32) formed so as to overlap the sub label perforation line 4 or in the vicinity thereof. The impact due to the break of the sub-label 2 affects the vicinity of the shrink perforation line 3, and the tubular shrink label 1 is broken along the first shrink perforation line 31 or the second shrink perforation line 32 and divided into two. It

16 and 17 are front views showing a process of removing the tubular shrink label with the sub label, and show a 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).

Particularly, when the sub-label perforation line 4 is formed over the entire length of the sub-label 2 in the vertical direction, 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 are formed over the entire length of the tubular shrink label 1 in the vertical direction, the bent portion (the tubular shape) The longitudinal first end 11 and the longitudinal second end 12) of the shrink label 1 can also be easily divided. Further, since the first shrink perforation line 31 that overlaps the sub label perforation line 4 and the second shrink perforation line 32 that corresponds to a position near the sub label perforation line 4 are formed on the tubular shrink label 1, the tubular shrink label 1 is tubular. 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, configurations and effects different from those of the above-described embodiment will be mainly described, and for similar configurations and the like, terms or reference numerals are directly used, The description of the configuration may be omitted.

[Second Embodiment]
FIG. 18 is a front view of a tubular shrink label with a sub label according to the second embodiment. FIG. 19 is an enlarged sectional view taken along line XIX-XIX in FIG. In the first embodiment described above, the vertical first end 21, the vertical second end 22 and the horizontal first end 23 of the sub label 2 are independent areas, but in the second embodiment, 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 continuous body of the tubular shrink label A with a sub-label (long tubular shrink label original fabric B) in which the second lateral end portion 25 is also an independent region, and the second embodiment has a second embodiment. It is a front view of such a long tubular shrink label original fabric. By cutting this long tubular shrink label original fabric B along the planned cutting line 6, the sub-labeled tubular shrink label A shown in FIG. 18 is obtained. Also in the present embodiment, a packaging body to which the tubular shrink label with the sub label is attached can be manufactured by the same manufacturing method as described above.

[Third Embodiment]
FIG. 21 is a front view of a tubular shrink label with a sub label according to the third embodiment. 22 is an enlarged cross-sectional view taken along the line XXII-XXII in 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 lateral direction across the shrink perforation line 3 in the attachment area. Only both sides are adhered to the outer surface of the tubular shrink label 1. In addition, the continuous body of the tubular shrink label A with the sub-label (the long tubular shrink label raw material B) is formed by continuously connecting the tubular shrink labels A with the sub-label at the planned cutting line 6. Therefore, the drawing is omitted. Also in the present embodiment, a packaging body to which the tubular shrink label with the sub label is attached can be manufactured by the same manufacturing method as described above.

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

[Fourth Embodiment]
FIG. 23: is a front view which shows the cylindrical shrink label 1 which comprises the cylindrical shrink label with a sublabel of 4th Embodiment. FIG. 24 is a front view showing a tubular shrink label 1 constituting another tubular 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 cylindrical shrink label 1 is shown by a chain double-dashed line. In the fourth embodiment, a cut 7 is formed in the plane of the tubular shrink label 1 so as to overlap the shrink perforation line 3. 23 and 24, the attachment area is not illustrated by dot-shaped hatching, but the attachment area is not particularly limited, and for example, any one of the first to third embodiments may be used. Can be an attachment area.

　The non-penetrating part of the perforation line disappears in the part where the linear cut line 7 is engraved on the shrink perforation line 3. Therefore, it can be said that the cut line 7 has a length that is several times to several tens of times longer than the length of the through hole of the perforation line. The cut line 7 can be formed at an arbitrary position of the shrink perforation line 3. By forming the cut line 7, the tubular shrink label 1 is easily broken along the shrink perforation line 3. The cut line 7 is preferably formed on at least one of the first shrink perforation line 31 and the second shrink perforation line 32.

Specifically, in the cylindrical shrink label 1 shown in FIG. 23, a linear cut 7 is formed so as to overlap the longitudinal middle portion of the first shrink perforation line 31. In the tubular shrink label 1 shown in FIG. 24, cuts 7 are formed so as to overlap the first longitudinal end and the second longitudinal end of the first shrink perforation line 31, respectively. The tubular shrink label 1 shown in FIG. 24 is a bent portion (first longitudinal end portion 11 and second longitudinal second portion of the tubular shrink label 1 that occurs when the tubular shrink label A with a sub-label is attached to an adherend. The cut 7 is formed at a position corresponding to the end 12).

Note that, although not particularly shown, the cut 7 may be formed so as to be overlapped with each of the first longitudinal end portion, the second longitudinal end portion, and the longitudinal midway portion of the first shrink perforation line 31. Further, in place of the first shrink perforation line 31, the cut 7 is formed in at least one location selected from the first longitudinal end, the second longitudinal end, and the midway longitudinal portion of the second shrink perforation line 32. It may be provided (not shown). The cut 7 may be formed so as to overlap both the first shrink perforation line 31 and the second shrink perforation line 32 (not shown).

In the case of the method of forming the sub-label perforation line 4 and the first shrink perforation line 31 at the same time as described above (see FIG. 12, etc.), the sub-label perforation line 4 is not cut and the first shrink perforation line 31 is cut. Is difficult to form. Therefore, when the manufacturing method for simultaneously forming the sub-label perforation line 4 and the first shrink perforation line 31 is performed, it is preferable to form the cut 7 on the second shrink perforation line 32. Also in the present embodiment, a packaging body to which the tubular shrink label with the sub label is attached can be manufactured by the same manufacturing method as described above.

[Fifth Embodiment]
FIG. 25: is a front view of the long tubular shrink label original fabric which concerns on 5th Embodiment. 25 is an enlarged cross-sectional view taken along the line XXV-XXV in FIG. In the above-described embodiment, the independent region of the sub label 2 is completely non-adhered to the outer surface of the tubular shrink label 1, but in order to prevent flapping of the lateral first end 23 of the sub label 2. The lateral first end 23 may be temporarily fixed in a spot manner.

With reference to FIGS. 25 and 26, for example, a temporary fixing portion 71 is provided pointwise near the first edge of the lateral first end portion 23 of the sub label continuum B2. The temporary fixing portions 71 are provided, for example, at regular intervals (in a longitudinal direction of the tubular shrink labels A with sub-labels that are continuously connected) in a spotwise manner in the vertical direction. The temporary fixing portion 71 is not particularly limited as long as it can attach the sub label 2 to the outer surface of the tubular shrink label 1 with a weak adhesive force such that it peels off with a slight force. Can be mentioned. Also in the present embodiment, by performing the same manufacturing method as described above and separating the tubular shrink label 1 and the sub label 2 that are temporarily fastened by the temporary fastening portion 71, the tubular shrink label with the sub label is obtained. A mounted package can be manufactured.

[Sixth Embodiment]
FIG. 27: is a front view of the long tubular shrink label original fabric which concerns on 6th Embodiment. 28 is an enlarged cross-sectional view taken along the line XXVII-XXVII in FIG. In the long tubular shrink label original fabric B of the above-described embodiment, the peripheral zone region 24 including the planned cutting line 6 and the lateral first end 23 of the sub label continuum B2 are independent regions. For example, as shown in FIGS. 27 and 28, only the peripheral band region 24 including the planned cutting line 6 in the sub label continuum B2 is set as an independent region, and all the regions other than the peripheral band region 24 are set as attached regions. It may have been done. The entire attachment area is adhered to the outer surface of the cylindrical shrink label continuum B1.

The long tubular shrink label original fabric B is also cut at the planned cutting line 6 to obtain individual tubular label shrink labels A with sub-labels. The direction first end 21 and the vertical second end 22 are independent areas, and the other areas are attachment areas (adhesive portions).

The tubular shrink label A with such a sub-label also has a longitudinal first end portion 21 and a longitudinal second end portion 22 of the sub-label 2 which are heat-shrinkable when heat-shrinkably attached to the adherend. The cylindrical shrink label 1 does not follow the cylindrical shrink label 1 and projects vertically from the bent portion of the tubular shrink label 1. In addition, in the long cylindrical shrink label original fabric B of this embodiment, the sub label perforation line 4, the first shrink perforation line 31, and the second shrink perforation line 32 are not formed, but if necessary, these Perforations may be formed. Also in the present embodiment, a packaging body to which the tubular shrink label with the sub label is attached can be manufactured by the same manufacturing method as described above.

[Seventh Embodiment]
FIG. 29: is a front view of the long tubular shrink label original fabric which concerns on 7th Embodiment. FIG. 30: is a perspective view of the elongate cylindrical shrink label original fabric which concerns on 7th Embodiment. In the long tubular shrink label original fabric B of each of the above-described embodiments, the long strip-shaped sub label continuous body B2 (a plurality of sheet-shaped sub labels are continuously connected to the outer surface of the tubular shrink label continuous body B1. However, the present invention is not limited to this, and for example, as shown in FIGS. 29 and 30, a plurality of sheet-shaped sub-labels 2 are provided on the outer surface of the tubular shrink label continuum B1. They may be attached side by side in the vertical direction.

It can be said that the long tubular shrink label original fabric B is a mode in which the long strip-shaped sub-label continuous body B2 in each of the above embodiments is cut into individual sub-labels 2. The long tubular shrink label original fabric B is obtained by attaching the sheet-shaped sub-labels 2 to the outer surface of the tubular shrink label continuous body B1 at intervals in the vertical direction. Then, the long tubular shrink label original fabric B is cut along the planned cutting line 6 (in this case, only the tubular shrink label continuous body B1 is cut between the sub labels 2 adjacent in the vertical direction). Thereby, as shown in FIG. 29, the tubular shrink label A with each sub-label is obtained. However, in the tubular shrink label A with a sub label obtained in the present embodiment, the vertical length of the sub label 2 is usually smaller than the vertical length of the tubular shrink label 1.
