Description

The present invention relates to a method for manufacturing a container equipped with a labeled tubular film to which a label having a sticking portion and a non-sticking portion is attached at a predetermined interval in the longitudinal direction of a long film body.

Conventionally, various products such as beverages, confectionery, cosmetics, and medicines are packaged in containers and boxes and distributed in the form of a package.
Labels are affixed to these packages for various purposes such as advertising of products, display of raw materials, and campaigns.
Among these labels, in order to make the product stand out mainly and enhance the advertising function, a label that is pasted with a part protruding from the package (this type of label is also referred to as a POP label. Is sometimes known).

This POP label is generally made of a flexible base material having a predetermined shape, and is composed of a sticking part that is stuck to the package and a non-sticking part that cannot be stuck to the package. The POP label is used with the non-sticking part protruding from the package.
Such a POP label attaching part is directly attached to a container or a packaging box. Alternatively, the POP label sticking part is a heat-shrinkable tubular film mounted on a container or the like (this kind of tubular film is also called a heat-shrinkable tubular label, a tubular shrink, a shrink label, etc.). It may be affixed.
A package in which a POP label is attached to a cylindrical film mounted on a container or the like is disclosed in, for example, Patent Document 1.

By the way, there are the following two methods for sticking the POP label sticking part to the tubular film and projecting the non-sticking part of the POP label.
One method is to attach the POP label affixing portion to the surface of the cylindrical film after the attachment so that the non-sticking portion of the POP label protrudes after the cylindrical film is heat-shrink mounted on the container. is there.
Another method is to stick a POP label sticking portion at a predetermined interval in the longitudinal direction of the tubular film elongated body in which the tubular films are continuously connected. This is a method in which a non-sticking portion of a POP label is protruded from a cylindrical film by cutting out a cylindrical film with a label and heat-shrinking the labeled cylindrical film onto a container. This latter method is a so-called pre-label method in which a POP label is attached in advance to a long tubular film.
Conventionally, Patent Document 2 discloses a pre-label method in which a tack label that can be applied to the entire surface (not a POP label) is previously attached to a long tubular film.
Japanese Patent Laid-Open No. 11-208667 JP 2000-112359 A

In the pre-label method, in order to continuously affix a plurality of POP labels to a long tubular film body, the following long tubular film body, long label supply body, and labeler (label sticking device) A sticking method using can be considered.
The tubular film elongated body is a long object in which heat-shrinkable tubular films are continuously connected, and the tubular film elongated body is obtained by forming the heat-shrinkable film into a tubular shape. . The label supply elongate body is a long object in which a plurality of POP labels are stuck side by side in the longitudinal direction of a long release paper.
The labeler is a peeling means for separating the label from the label supply elongated body and a conveying means for feeding the tubular film elongated body to one side in the longitudinal direction, and has a tip near the surface of the tubular film elongated body. A peel plate on which the part is arranged, and a transport and recovery means for collecting the release paper that has been fed to the peel plate and fed at the leading end of the peel plate.
Using the labeler, the label supply elongate body is sent to the peel plate while feeding the tubular film elongate body to one side in the longitudinal direction, and the label supply elongate body is provided at the tip of the peel plate. By reversing the release paper, the label is peeled off from the release paper, and the peeled label is attached to the surface of the tubular film elongate body and transferred, thereby changing the predetermined length in the longitudinal direction of the tubular film elongate body. The POP label can be applied continuously by opening.

  However, since the POP label has a non-sticking portion, when the POP label is peeled off from the release paper at the tip of the peel plate, the POP label is scattered or misaligned, and the POP label is placed at a predetermined position on the long tubular film. The label may not stick.

An object of the present invention is to provide a label supply long body when manufacturing a labeled cylindrical film mounting container using a long film with a label on which a label is attached with a predetermined interval in the longitudinal direction of the long film. It is devised so that the label peeled off can be reliably affixed to a predetermined position of the long film body.

Under the above-mentioned objectives, the present inventors have examined various cases with regard to the label supply elongated body by paying attention to the labeling direction of the label having the pasting part and the non-sticking part.
As described above, when producing a long film with a label, while feeding the long film, the long label supply is sent to the peel plate, and the label is peeled off from the release paper at the tip of the peel plate, The label is attached to the surface of the long film which is sequentially fed and transferred.
As shown in FIG. 12, the label 30 of the label supply elongate body 60 positions the sticking part 310 of the label 30 on the downstream side in the feed direction of the label supply elongate body 60, and the non-sticking part 320 of the label 30 is When the label supply elongate body 60 is attached on the upstream side in the feed direction, the label 30 peeled off from the label supply elongate body 60 may not be attached to the surface of the film elongate body 20.

Specifically, as a result of only the release paper 610 being inverted from the label supply elongated body 60 at the leading end 520a of the peel plate 520, the leading end of the label 30 (the end of the label supply elongated body on the downstream side in the feed direction). ) Begins to peel off.
The tip portion 520 a of the peel plate 520 is disposed in the vicinity of the surface of the long film body 20 so as not to contact the long film body 20. For this reason, there is a slight gap between the tip 520 a of the peel plate 520 and the surface of the long film body 20.
As described above, when the label supply elongate body 60 with the label 30 attached is used by positioning the attaching portion 310 of the label 30 on the downstream side in the feed direction of the label supply elongate body 60, The tip portion of the label 30 that starts to peel off corresponds to the sticking portion 310 of the label 30. For this reason, in the said clearance gap, although the edge part of the sticking part 310 of the label 30 is in the state which is not in contact with the surface of the film elongate body 20, the sticking part 310 of the label 30 is completely from the release paper 610. (See FIG. 12).
As described above, when the sticking portion 310 of the label 30 is not in contact with either the long film body 20 or the release paper 610, the label 30 is scattered by the repulsive force of the label or external influence (for example, wind). Alternatively, since the position is shifted, the label 30 cannot be attached to a predetermined position on the surface of the long film body 20.

Then, the manufacturing method of the cylindrical film mounting container with a label of this invention has the long film body in which the heat-shrinkable film was connected continuously, and a plurality of labels arranged in the longitudinal direction of the long release paper. Attached label supply elongate body, and each label has an affixing portion that can be affixed to the surface of the film elongate body and a non-adhering portion that cannot be affixed to the surface of the elongate film body, Each label has the sticking part positioned on the upstream side in the feed direction of the label supply elongate body, and the non-sticking part is located on the downstream side in the feed direction of the label supply elongate body to the release paper. are attached, the distal end portion of the peel plate in the vicinity of the surface of the film long body arranged, while feeding the film long body and its one longitudinal side, the peel plate the label supplying long body To the tip of the peel plate In the section, the release paper of the label supply elongate body is reversed, the label is peeled off from the release paper, and the peeled label is transferred to the surface of the elongate film body to change the length of the elongate film body. obtaining a label with the film long body by continuously sticking a label with a predetermined interval to obtain a labeled tubular film long body forming said label with the film long body in a cylindrical shape And after obtaining the tubular film with a label by cutting the elongated tubular film with the label along a planned cutting line, the boundary between the pasting part and the non-pasting part of the label is a trunk part and a shoulder part of the container The label-attached cylindrical film is externally fitted to the container so that it substantially coincides with the boundary portion of the label, and then heat-shrinks to cause the non-sticking portion of the label to protrude away from the cylindrical film. Labeled tubular film And a step of mounting the container, the.
Moreover, the manufacturing method of the cylindrical film mounting container with another bell of this invention is the cylindrical film elongate body with which the heat-shrinkable cylindrical film was connected continuously, and the release paper with which several labels are elongate. Label supply elongate affixed side by side in the longitudinal direction, and each label is affixed to the surface of the tubular film elongate and affixed to the surface of the tubular film elongate A non-sticking portion that is impossible, and each label has the sticking portion positioned upstream in the feed direction of the label supply elongate body, and the non-sticking portion is downstream in the feed direction of the label supply elongate body. The tip of the peel plate is disposed in the vicinity of the surface of the tubular film elongated body, and the tubular film elongated body is moved to one side in the longitudinal direction. The label supply elongated body is fed to the peel plate while feeding By reversing the release paper of the label supply elongate body at the front end of the peel plate to peel the label from the release paper, and transferring the peeled label to the surface of the tubular film elongate body, A step of obtaining a tubular film long body with a label by continuously sticking labels with a predetermined interval in the longitudinal direction of the long film body, and cutting the long tubular film with a label along a planned cutting line After obtaining the labeled tubular film, the boundary portion between the label pasting portion and the non-sticking portion is substantially coincident with the boundary portion between the body portion and the shoulder portion of the container. After being externally fitted to the container, it is heated and shrunk to cause the non-sticking part of the label to protrude away from the cylindrical film and to attach the labeled cylindrical film to the container.

In the manufacturing method of the tubular film-attached container with a label according to the present invention, the label attaching portion is positioned on the upstream side in the feeding direction of the label supply elongated body, and the non-labeling portion of the label is fed in the feeding direction of the label supply elongated body. It is characterized by using a label supply elongate body that is positioned downstream and each label is affixed to a release paper.
When such a label supply elongate body is used, the leading end portion of the label peeled off at the leading end portion of the peel plate corresponds to the non-sticking portion of the label.
Even if the non-sticking part (tip part) of the label is separated from the release paper at the tip part of the peel plate, the label sticking part (rear edge part) located on the upstream side in the feed direction of the label supply elongated body is stuck on the release paper. attached. Therefore, the end of the non-sticking portion of the label comes into contact with the surface of the long film body while the sticking portion of the label is stuck to the release paper. Furthermore, since the label is sent to the long film side, the non-sticking part of the label follows the surface of the long film, and the sticking part of the label is completely separated from the release paper. Without moving to the surface of the long film.
Thus, according to this onset bright, without scattering the label peeled from the label supply long body, it can be attached to ensure the label at a predetermined position of the film long body.

The manufacturing method of the cylindrical film mounting container with a label of this invention can affix the label which has a sticking part and a non-sticking part on the predetermined position of a film elongate body reliably.
Therefore, according to the manufacturing method of the present invention, it is possible to reliably produce the labeled film long body that POP label is affixed at predetermined intervals in the longitudinal direction of the film long body, such long body By attaching the tubular film with a label obtained by cutting to a container, a tubular film-attached container with a label from which a non-sticking part protrudes can be obtained.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<First embodiment of the long film with label>
In this embodiment, with a label, a label is attached to a tubular film elongated body (a film elongated body in which a heat-shrinkable tubular film is continuously connected) in which a heat-shrinkable film is formed into a tubular shape. A preferred embodiment of the long tubular film and the method for producing the same will be described.
1 to 3, a long tubular film 1 with a label according to the present invention includes a long tubular film 2 continuously connected with a tubular film that can be mainly thermally contracted in the circumferential direction, and the tubular film. And a label 3 affixed at a predetermined interval in the longitudinal direction X of the long film body 2.
The tubular film elongated body 2 is a long object in which a plurality of tubular films are continuously connected such that one side in the longitudinal direction X is the upper end side of the tubular film.
The label 3 has an affixing portion 31 that can be affixed to the surface of the long tubular film 2 and a non-adhesion portion 32 that cannot be affixed to the surface of the long tubular film 2. Each label 3 has its non-sticking part 32 positioned on one side in the longitudinal direction X of the tubular film elongated body 2 and its sticking part 31 positioned on the other side in the longitudinal direction X of the tubular film elongated body 2. And it is affixed on the surface of the cylindrical film elongate body 2 via the affixing part 31, respectively.

By cutting the long tubular film 2 in the width direction Y (direction perpendicular to the longitudinal direction X) along the planned cutting line Z, as shown in FIG. Can be obtained.
Note that the planned cutting line Z is not actually printed on the long tubular film body 2, but is a virtual line indicating a portion to be cut. In one actual machine, usually, a small mark for mechanically reading the cutting site is printed at a predetermined interval in the longitudinal direction X of the long tubular film 2, and the tubular film is located at the position of this mark. The long body 2 is cut in the width direction Y. In other actual machines, the long tubular film 2 may be cut at a predetermined position with a POS display such as a barcode or a design display such as an arbitrary picture as a mark.

Each label 3 is positioned in the vicinity of the planned cutting line Z so that the upper end edge 3a of each label 3 does not overlap with the planned cutting line Z of the long tubular film 2. It is affixed.
By sticking the label 3 at such a position, it is possible to prevent the label 3 from being cut when the long tubular film 2 is cut along the planned cutting line Z.
In the tubular film 10 with a label obtained by cutting the long tubular film 2 along the planned cutting line Z, the non-sticking portion 32 of the label 3 is located on the upper side of the tubular film, and the upper end of the label 3 The edge 3a is located in the vicinity of the upper edge 10a of the tubular film.

As shown in FIG. 5, the tubular film 10 with a label is formed by externally fitting the tubular film 10 with a label to a container 9 with the upper end edge 10 a of the tubular film facing upward, and heat-shrinking it. Can be attached to the container 9.
When the labeled tubular film 10 is externally fitted to the container 9, the boundary part 93 of the label 3 and the boundary part 33 of the non-sticking part 32 substantially coincide with the boundary part 93 of the body part 91 and the shoulder part 92 of the container 9. Thus, if the tubular film with label 10 is externally fitted to the container 9, the upper region of the tubular film that contracts greatly along the shoulder 92 of the container 9 is separated from the non-sticking portion 32 of the label 3. The non-sticking portion 32 can be raised and protrude from the container 9.
The shoulder portion 92 of the container 9 is a diameter-reduced portion that decreases in diameter as it goes upward, and the body portion 91 of the container 9 and the boundary portion 93 of the shoulder portion 92 are reduced in diameter above the body portion 91. This is the beginning.
Hereinafter, the tubular film long body 1 with a label will be described while explaining each component.

The tubular film elongated body 2 is formed by forming a heat-shrinkable film that mainly heat-shrinks in a first direction into a tubular shape so that the first direction is a circumferential direction, and overlapping both end portions thereof. It is formed in a cylindrical shape by bonding 22 with a solvent or an adhesive. This overlapped portion is generally called a center seal portion 22.
In the present invention, the term “long” means that one length is sufficiently longer than the other length, for example, one length is 10 times or more longer than the other length. Is included.

The material of the heat-shrinkable film constituting the long tubular film 2 is not particularly limited as long as it has the property of being heat-shrinkable at least in the first direction (circumferential direction when formed into a tubular shape, hereinafter the same). Without limitation, for example, heat from polyester resins such as polyethylene terephthalate and polylactic acid, olefin resins such as polypropylene, styrene resins such as polystyrene and styrene-butadiene copolymers, cyclic olefin resins, vinyl chloride resins, etc. A synthetic resin film, a foamed resin sheet, or the like made of one kind selected from plastic resins or a mixture of two or more kinds can be used. A laminated film in which two or more kinds of resins having heat shrinkability are laminated can also be used. Furthermore, a laminated film in which a heat insulating layer such as a nonwoven fabric or a foamed resin sheet and other functional layers are laminated on a synthetic resin film can also be used.
Although the thickness of a heat-shrinkable film is not specifically limited, Usually, it is about 20-100 micrometers.

The heat shrink property of the heat shrinkable film is not particularly limited. Usually, the heat shrink rate in the first direction (immersion in 90 ° C. warm water for 10 seconds) is about 40% or more, preferably about 50% or more. is there. The heat-shrinkable film may be slightly heat-shrinked in the second direction (the direction perpendicular to the first direction in the film surface), and the heat-shrinkage rate in the second direction (in 90 ° C. warm water) 10 seconds immersion) is about -3 to 10%.
However, heat shrinkage rate (%) = [{(original length in the first direction (or second direction)) − (length after immersion in the first direction (or second direction))} / (first Original length of direction (or second direction)]] × 100.

For example, a well-known design print 21 such as a trade name, a trademark, or a pattern design is printed on the long tubular film 2 in a single color or a multicolor print by gravure printing or the like.
The design printing 21 is printed with the direction aligned in the longitudinal direction X of the tubular film elongated body 2 for each set of designs. In each drawing, the display represented by the design print 21 is represented by the letters “design” for convenience. As shown in each drawing, the design of the design print 21 is printed in such a direction that the upper end edge 10a of the tubular film can be visually recognized satisfactorily.

As shown in FIG. 6, the label 3 includes a pasting portion 31 that can be pasted on the surface of the long tubular film 2, and a non-sticking portion 32 that cannot be pasted on the surface of the long tubular film 2. Have. Therefore, a pasting portion 31 is formed in one area of the label 3, and a non-pasting portion 32 is formed in the other area of the label 3. In addition, the code | symbol 33 shows the boundary (boundary part 33) of the sticking part 31 and the non-sticking part 32. FIG.
The non-sticking portion 32 of the label 3 is a protruding portion that protrudes away from the tubular film when the tubular film is heat-shrink mounted on the container 9.

The size of the label 3 is not particularly limited and can be set to various sizes. Moreover, the length of the sticking part 31 and the non-sticking part 32 of the label 3 is not particularly limited, and can be set to various lengths.
In general, the longitudinal direction of the label 3 (the longitudinal direction of the label means a direction that becomes the longitudinal direction X of the tubular film elongated body 2 when being attached to the tubular film elongated body 2. Similarly, the length D is preferably 10 mm to 50 mm, and more preferably 20 mm to 40 mm. If the length D of the label 3 in the longitudinal direction is too short, the transfer from the label supply long body to the tubular film long body 2 may not be performed satisfactorily. If the length D is too long, the label This is because there is a risk of inconvenience such as bending of 3.
The length E of the label 3 in the horizontal direction (the direction perpendicular to the vertical direction in the surface of the label 3) is preferably 10 mm to 30 mm, and more preferably 10 mm to 15 mm.
Moreover, 6 mm-34 mm are preferable and, as for the length F of the vertical direction of the sticking part 31 of the label 3, 14 mm-26 mm are more preferable. If the length F of the sticking portion 31 in the vertical direction is too short, the label 3 may be carelessly peeled off. If the length F is too long, the length of the non-sticking portion 32 becomes relatively short. It is. On the other hand, the longitudinal length G of the non-sticking part 32 of the label 3 is preferably 3 mm to 17 mm, and more preferably 7 mm to 13 mm. This is because if the length G of the non-sticking portion 32 in the vertical direction is too short, the protruding length of the label 3 becomes short, and if the length G is too long, the length of the sticking portion 31 becomes relatively short. .

As shown in FIG. 7, the layer structure of the label 3 includes a base material 41, an adhesive layer 42 laminated on the entire back surface of the base material 41, and a concealing layer laminated on the other region of the back surface of the adhesive layer 42. 43. In addition, although various advertisements, such as a campaign application point and a brand name, are printed on the surface and the back surface of the base material 41 or the surface or the back surface of the base material 41 , this is not illustrated. Further, the layer structure of the label 3 may be a multilayer structure in which two layers of base materials are laminated so as to be peelable.
In the range where the concealing layer 43 is provided, the adhesive layer 42 is not exposed, and thus this range becomes the non-sticking portion 32 of the label 3. On the other hand, the adhesive layer 42 is exposed in a range where the concealing layer 43 is not provided, and thus this range becomes the sticking portion 31 of the label 3.

  The shape of the base material 41 (label 3) in plan view is not particularly limited. For example, the base material 41 (label 3) may have a substantially rectangular shape in plan view or a substantially circular shape in plan view or a substantially elliptical shape in plan view. Good.

The base material 41 constituting the label 3 is formed of a flexible non-heat-shrinkable sheet (the sheet means a sheet generally including a film). This non-heat-shrinkable sheet refers to a sheet that does not substantially heat shrink at a temperature (heat shrinkage temperature) when the tubular film is heat-shrinked. The sheet that does not substantially heat shrink includes the case where the sheet does not shrink at all at the heat shrink temperature of the tubular film, and the heat shrinkage is ± 5% or less in any direction (the heat shrinkage is measured by the above method). (The minus value means expansion) and includes the case of heat shrinkage. This is because if the sheet does not shrink at all, the options of the sheet are limited. On the other hand, even if a sheet having a thermal shrinkage rate of about ± 5% or less is used as the base material 41, there is no problem in the appearance of the label 3. It is.
In addition, the heat shrink temperature of a cylindrical film means the temperature which can be heat-shrinked to such an extent that a cylindrical film adheres along the outer surface of a container. The heat shrink temperature usually includes a temperature at which the outer surface temperature of the tubular film is 60 ° C to 120 ° C, preferably 80 ° C to 100 ° C.

As the base material 41, for example, paper, synthetic paper, a non-stretched or uniaxially or biaxially stretched synthetic resin sheet, a metal vapor deposition sheet, a laminate of these various sheets, and the like can be used.
Although the thickness of the base material 41 of the label 3 is not specifically limited, For example, it is about 30-200 micrometers.

The adhesive layer 42 is provided by applying an adhesive to the entire back surface of the substrate 41. The pressure-sensitive adhesive may be provided in a solid shape on the entire back surface of the base material 41, or may be provided in a mesh shape.
As the pressure-sensitive adhesive, known pressure-sensitive pressure-sensitive adhesives such as rubber, acrylic and urethane can be used.

The concealing layer 43 covers the adhesive layer 42 and is applied to conceal the adhesive force. The concealing layer 43 can be provided, for example, by applying a known non-adhesion process such as applying an ultraviolet curable ink to a predetermined region of the adhesive layer 42. Further, instead of non-adhesion processing by printing such as application of ultraviolet curable ink, a synthetic resin film may be laminated and adhered to a predetermined region of the adhesive layer 42, for example.
A small hole may be formed in the surface of the masking layer 43. Since the hole has no concealing layer (not subjected to non-adhesion treatment), the adhesive layer 42 is partially exposed. By forming such a small hole, the non-sticking portion 32 of the label 3 can be slightly attached to the release paper, and the non-sticking portion 32 of the label 3 can be inadvertently rolled from the long label supply body. Can be prevented.

  In the illustrated form, the adhesive layer 42 is provided on the entire back surface of the base material 41 in order to form the affixing portion 31 and the non-adhesion portion 32 of the label 3, and the concealing layer 43 is provided in a corresponding area of the non-adhesion portion 32. Although it consists of the provided structure, it can also be changed into the layer structure in which the adhesion layer 42 was provided only in the area | region equivalent to the sticking part 31 among the back surfaces of the base material 41, for example.

  Each label 3 has its non-sticking part 32 positioned on one side in the longitudinal direction X of the tubular film elongated body 2 and its sticking part 31 positioned on the other side in the longitudinal direction X of the tubular film elongated body 2. And it is affixed on the surface of the cylindrical film elongate body 2 via the affixing part 31, respectively. Preferably, each label 3 is affixed with the boundary 33 substantially parallel to the planned cutting line Z. In this embodiment, each label 3 is affixed while avoiding the center seal portion 22 of the tubular film elongated body 2.

Furthermore, each label 3 is affixed with the upper end edge 3 a of the label 3 positioned in the vicinity of the planned cutting line Z of the tubular film elongated body 2.
Preferably, each label 3 is affixed in the vicinity where the distance A from the upper edge 3a of the label 3 to the planned cutting line Z of the long tubular film 2 satisfies the following relational expression.
Formula: 0 <A <B (1-cos α).
However, in the formula, “A” indicates the planned cutting line Z of the long tubular film 2 from the upper edge 3a of the label 3 (the planned cutting line Z corresponds to the upper edge 10a of the tubular film before shrinking). (Refer to FIG. 1). In the formula, “B” is from the boundary portion 33 of the label 3 to the planned cutting line Z of the long tubular film 2 (the planned cutting line Z corresponds to the upper edge 10a of the cylindrical film before contraction). The distance is represented (see FIG. 1). “Α” represents an angle formed by the inner surface of the tubular film 81 when fitted and the outer surface of the tubular film 82 after heat shrinkage (see FIG. 8B).
The tubular film 81 at the time of external fitting of the above “α” is the label-formed tubular film 10 obtained by cutting along the planned cutting line Z of the tubular film long body 2 and the boundary portion 33 of the label 3 is This refers to a cylindrical film that is externally fitted to the container 9 so as to substantially coincide with the boundary portion 93 between the body portion 91 and the shoulder portion 92 of the container 9 (see FIG. 8A). The inner surface of the tubular film 81 at the time of external fitting is substantially parallel to the tangent line of the body portion 91 of the container 9.
The above-mentioned tubular film 82 after heat shrinkage of “α” refers to a case where the tubular film with label 10 fitted on the container 9 is heat-shrinked so as to be closely adhered along the shoulder 92 of the container 9. (Refer FIG.8 (b)). Since the outer surface of the tubular film after the heat shrinkage is substantially parallel to the inclination of the shoulder portion 92 of the container 9, the “α” substantially matches the inclination angle of the shoulder portion 92 of the container 9. .

If the distance from the upper edge 3a of the label 3 to the planned cutting line Z of the labeled tubular film elongated body 1 satisfies the above relational expression, on the planned cutting line Z of the tubular film long body 2, Since a part of the label 3 does not overlap, the long tubular film 1 with a label can be cut without losing the label 3.
Furthermore, if the obtained tubular film 10 with a label is heat-shrink mounted on the container 9, as shown in FIG. 5, the upper end edge 3a of the label 3 can be protruded above the upper end edge 10a of the tubular film. it can.

<1st Embodiment of the manufacturing method of the cylindrical film elongate body with a label>
Next, the manufacturing method of the said cylindrical film elongate body 1 with a label is demonstrated.
In the following description of the manufacturing method, the structure of the long tubular film 1 with a label, the long tubular film 2 and the label 3, the position where the label 3 is attached, etc. 1 is the same as the first embodiment.

A tubular film elongated body 2 in which heat-shrinkable tubular films are continuously connected is prepared. The long tubular film 2 is usually stored and transported in a roll form.
On the other hand, a label supply elongated body 6 is prepared in which a plurality of labels 3 are stuck side by side in the longitudinal direction of the long release paper 61 (see FIG. 9). The label supply elongate body 6 is usually used for storage and transportation in a form wound in a roll shape with the label 3 being attached on the outside.
The label 3 of the label supply elongate body 6 has the base material 41, one region of the base material 41 is a pasting portion 31, and the other region of the base material 41 is a non-sticking portion 32.
Each label 3 is affixed to the release paper 61 with the affixing portion 31 positioned on one side in the longitudinal direction of the release paper 61 and the non-adhesion portion 32 positioned on the other side in the longitudinal direction of the release paper 61. .

Using the labeler, the label 3 of the label supply elongated body 6 is stuck on the surface of the tubular film elongated body 2.
As shown in FIG. 9, the labeler includes a conveying roller 51 for feeding the long tubular film 2, a peel plate 52 for separating the label 3 and the release paper 61 from the long label supply 6, and a label supply length. It has a conveyance collection roller (not shown) that sends the scale 6 to the peel plate 52 and collects the release paper 61, and a pressing roller 53 that presses the upper surface of the attached label 3. The peel plate 52 is a plate-like body formed in an acute angle triangular shape when viewed from the side. The peel plate 52 is disposed such that a tip end portion 52 a (acute angle portion) thereof is positioned in the vicinity of the surface of the long tubular film body 2. The distance between the front end portion 52a of the peel plate 52 and the surface of the long tubular film body 2 is not particularly limited, but when the distance is too short, the front end portion 52a of the peel plate 52 is long tubular film length. There is a risk that the surface of the body 2 may be damaged and the surface may be damaged. On the other hand, if the distance is too long, the label 3 peeled off by the peel plate 52 cannot be transferred to the surface of the long tubular film 2. (Depending on the size of label 3). Considering this point, the lower limit of the distance between the tip 52a of the peel plate 52 and the surface of the long tubular film 2 is preferably 2 mm or more, more preferably 3 mm or more, and most preferably 4 mm or more. Moreover, although the upper limit of the said distance changes with the magnitude | sizes of the label 3 to be used, for example, when using the label 3 whose vertical length D of the label 3 is 10 mm to 50 mm, 7 mm or less is preferable, 6 mm or less is more preferable.

The cylindrical film elongate body 2 is fed by the transport roller 51 of the labeler with the longitudinal direction X one side (upper end side of the tubular film) of the tubular film elongate body 2 as the head. In the figure, an arrow L indicates the feeding direction of the tubular film elongated body 2.
In synchronization with the feeding of the long tubular film 2, the label supply long body 6 is fed to the upper surface of the peel plate 52, with the one side in the longitudinal direction of the release paper 61 as the leading edge, by the transport and collection roller of the labeler. . Therefore, the label supply elongate body 6 has the sticking portion 31 of each label 3 positioned on the upstream side in the feed direction of the label supply elongate body 6 and the non-sticking portion 32 of the label 3 is the label supply elongate body 6. Is sent to the upper surface of the peel plate 52. In the drawing, an arrow M indicates the feeding direction of the label supply elongate body 6. The feed direction M of the label supply elongated body 6 and the feed direction L of the tubular film elongated body 2 are the same when viewed from a direction perpendicular to the surface of the film elongated body 2.
The feeding of the label supply elongate body 6 is not the same as the feeding method and feeding speed of the tubular film elongate body 2, but is performed by intermittent feeding in which the length of one label is frame-fed.

At the tip 52a of the peel plate 52, only the release paper 61 is reversed to the lower surface of the peel plate 52 and collected. In the drawing, an arrow N indicates the feeding direction (collection direction) of the release paper 61.
When the release paper 61 is reversed and collected at the front end 52 a of the peel plate 52, the front end (non-sticking portion 32) of the label 3 is separated from the release paper 61. Further, by collecting the release paper 61, the label 3 is sent out, and the end of the non-sticking portion 32 of the label 3 starts to contact the surface of the tubular film elongated body 2. When the end of the non-sticking portion 32 of the label 3 starts to contact the surface of the long tubular film body 2, the rear end (sticking portion 31) of the label 3 is stuck to the release paper 61. For this reason, since the label 3 is in contact with the long tubular film 2 and the release paper 61, there is no possibility that the label 3 is scattered due to, for example, wind.
Then, by collecting the release paper 61 and moving the long tubular film body 2, the label 3 is attached to the release paper 61 while the non-sticking section 32 follows the surface of the long tubular film body 2. It moves completely away from the surface, moves to the surface of the long tubular film 2, and the sticking part 31 of the label 3 sticks to the surface of the long tubular film 2. Thereafter, the label 3 is pressed by the pressing roller 53.
As described above, each label 3 is attached to the surface of the long tubular film 2 so that the label 3 is attached at a predetermined interval in the longitudinal direction X of the long tubular film 2. The labeled tubular film elongated body 1 can be obtained.

According to the above manufacturing method, when the label 3 is peeled from the long label supply body 6, the label 3 can be reliably attached to a predetermined position of the long tubular film 2 without scattering the label 3. .
In addition, according to the manufacturing method of the present invention, the label 3 can be reliably attached to a predetermined position of the long tubular film 2, so that the upper edge 3 a of each label 3 is a cylinder as described above. It can affix on the vicinity (preferably the position which satisfies the said relational expression) of the cutting-like line Z of the long film-like body 2.

<2nd Embodiment of the manufacturing method of a label cylindrical film elongate body>
In the first embodiment, the label 3 is attached while avoiding the center seal portion 22 of the long tubular film body 2, but the label 3 may be attached so as to overlap the center seal portion 22.
In this case, as shown in FIG. 10, even if a cut 7 for dividing the center seal portion 22 is formed at a position slightly below the planned cutting line Z in the center seal portion 22 of the long tubular film body 2. Good. The long tubular film 2 with the cuts 7 formed is fed by the transport roller 51 in the same manner as in the manufacturing method of the first embodiment, and the label 3 is affixed to the long tubular film 2. Is done. Preferably, the label 3 is stuck on the center seal portion 22 of the tubular film elongated body 2 so that the sticking portion 31 of the label 3 is positioned so as to cover the cut 7 of the tubular film elongated body 2.
In the long tubular film body 2 shown in FIG. 10, perforation lines (not shown) extending in the longitudinal direction along both sides or one side of the center seal portion 22 may be formed. This perforation line is preferably formed in the vicinity of both end portions of the cut 7.
As shown in FIG. 10, the long tubular film 1 with a label obtained in this way is formed in the center seal portion 22 with the upper end edge 3 a of the label 3 positioned in the vicinity of the planned cutting line Z. An affixing portion 31 of the label 3 is affixed to the cut line 7. According to the manufacturing method of the present invention, since the label 3 can be reliably affixed to a predetermined position, each label is aligned so as to cover the cut 7 formed in the center seal portion 22 of the long tubular film body 2. 3 can be attached.

The labeled tubular film elongated body 1 is cut along the planned cutting line Z in the same manner as in the first embodiment, whereby one labeled tubular film 10 is obtained. When the tubular film with label 10 is heat-shrink mounted on the container 9, the non-sticking portion 32 of the label 3 protrudes as in the first embodiment (see FIG. 11). But the non-sticking part 32 of the label 3 does not need to protrude.
When the attached tubular film 10 with label is removed from the container 9, the film starts to tear from both ends of the cut 7 by picking the non-sticking portion 32 of the label 3 and pulling it outward and downward. It can be cut out (represented by a two-dot difference line in FIG. 11). Since the center seal portion 22 is a portion where two overlapped films are bonded, the center seal portion 22 is not torn in the middle of cutting, and the center seal portion 22 in the range from the cut 7 to the lower edge of the tubular film can be easily cut off. it can. Thus, the cylindrical film from which most of the center seal portion 22 is cut can be easily removed from the container 9.
