Description

  TECHNICAL FIELD The present invention relates to a heat-shrinkable cylindrical label that is partially cut off after use, and a container with a label on which the heat-shrinkable cylindrical label is attached.

2. Description of the Related Art Conventionally, heat-shrinkable cylindrical labels that can be mounted on the body of a container by heat-shrinking are well known.
Since such a heat-shrinkable cylindrical label is attached to a container, it is greatly heat-shrinked in the circumferential direction. Thus, the heat-shrinkable cylindrical label that is largely heat-shrinked in the circumferential direction usually has a tubular body in which a stretched film is formed in a tubular shape so that the main stretching direction is the circumferential direction.

By the way, a container with a handle is known as a relatively large container filled with liquid detergent, oil, beverage or the like. In some cases, the heat-shrinkable cylindrical label is also attached to a container with such a handle.
As a heat-shrinkable cylindrical label to be mounted on the container with a handle, in Patent Document 1, a perforation extending in the vertical direction and the circumferential direction is formed, and a predetermined region surrounded by the perforation is cut off, thereby A sleeve (heat-shrinkable cylindrical label) is disclosed in which two holes can be formed at positions corresponding to the recesses.
Such a heat-shrinkable cylindrical label can form a cut window portion at a position corresponding to the recess of the container by cutting a partial region of the film along a perforation line extending in the longitudinal direction and the circumferential direction. For this reason, the recess of the container is not closed by attaching the cylindrical label, and a finger can be put into the recess of the container through the window formed in the heat-shrinkable cylindrical label and held.

However, the heat-shrinkable cylindrical label has a cylindrical body in which a stretched film is formed in a cylindrical shape so that the main stretching direction is the circumferential direction as described above. For this reason, the heat-shrinkable cylindrical label has a characteristic that it is very difficult to tear in the vertical direction but easily tears in the circumferential direction. In particular, when a polyester stretched film such as a uniaxially stretched polyethylene terephthalate film is used as the stretched film, the tearability in the circumferential direction tends to be strong.
Therefore, even if the conventional heat-shrinkable cylindrical label is cut along the perforation line extending in the vertical direction, cracks are likely to occur in the circumferential direction during the cutting. In this regard, even if a crack occurs in a part of the area, the part of the area is a part to be removed and is not used thereafter.
However, when a crack occurs on the side opposite to the partial region, the edge of the formed window portion does not become a beautiful line mark. As a result, when the container has a recess through the window, there is a problem in that the film portion constituting the edge of the window rises and makes it difficult to hold the container. Further, if the edge of the window portion is turned, the design is hidden or distorted, which is not preferable in appearance.

JP-T 8-509190

  Therefore, the present invention provides a heat-shrinkable cylindrical shape that does not cause cracks at the edges of the formed window when cutting out a partial region, and can maintain a good appearance after cutting. It is an object to provide a label and a labeled container in which the label is attached to the container.

The heat-shrinkable cylindrical label according to the present invention is a tube in which two vertical cutting auxiliary lines extending in the vertical direction with a predetermined interval in the circumferential direction are formed by being thermally contracted in the circumferential direction and being attached to the container. has Jo body, after heat shrinkage fitted to the container, said portion of the tubular body divided in accordance with two vertical coring auxiliary line, in a partial region between the two longitudinal cut extension line a heat-shrinkable tubular label is made possible cut in the tubular body, the only part area opposite, provided the two longitudinal cut film thickness portion along the auxiliary line, respectively The one thick film portion is composed of a tear tape attached from the upper edge to the lower edge of the tubular body, and the other film thick portion is composed of a center seal portion of the tubular body. It is characterized by being.

Since the heat-shrinkable cylindrical label is provided with a thick film portion along the vertical cutting auxiliary line only on the side opposite to the partial area, a part of the cylindrical body is utilized using the vertical cutting auxiliary line. Can be prevented from cracking on the side opposite to the partial region.
Therefore, after the heat-shrinkable cylindrical label cuts out a part of the area, the edge of the window becomes a beautiful line mark according to the vertical cutting auxiliary line. In addition, since the edge of the window is difficult to bend, it is possible to prevent distortion of the design after cutting.

Further, in the heat- shrinkable cylindrical label of the present invention , two of the vertical cut auxiliary lines are formed at a predetermined interval in the circumferential direction, and the partial area is between the two vertical cut auxiliary lines. It is an area | region, and the said film thick part is each provided along two vertical cutting auxiliary lines only in the other side and a partial area | region.

Since such a heat-shrinkable cylindrical label is provided with two vertical cut auxiliary lines, a partial region existing between the two vertical cut auxiliary lines can be easily cut out. Furthermore, since the cylindrical body is provided with the thick film portions along the two longitudinal cut auxiliary lines only on the side opposite to the partial area, the window portion formed after the partial area is cut off. The edge of becomes a beautiful streak.

Further, in the heat- shrinkable cylindrical label of the present invention, the one film thick part is composed of a tear tape attached from the upper edge to the lower edge of the cylindrical body, and the other film thick part is a cylindrical shape. It consists of the center seal part of the body. Therefore, the attachment work of the tear tape can be reduced as compared with the case where each of the thick film portions provided along the two vertical cutting auxiliary lines is composed of the tear tape.

Labeled container according to the present invention, the upper Symbol heat-shrinkable tubular label are heat-shrunk and attached container recessed portion formed in the peripheral wall, a part region of the tubular body, the container of the recess It is attached to correspond to.

Since the heat-shrinkable cylindrical label and the labeled container of the present invention are provided with a thick film portion along the vertical cutting auxiliary line only on the side opposite to the partial area, the cylindrical body according to the vertical cutting auxiliary line. It is possible to prevent a crack from occurring on the side opposite to the partial region when part of the substrate is divided in the vertical direction.
Accordingly, the heat-shrinkable cylindrical label is formed with beautiful line marks on the edge of the window portion to be formed, and can prevent the edge of the window portion from dripping greatly, so that the appearance is not impaired. It becomes good.

Hereinafter, the present invention will be specifically described with reference to the drawings.
However, “first”, “second”, and the like are added as prefixes of terms indicating the same configuration, and this is added to distinguish the terms, and means superiority or inferiority of members, order, and the like. Not what you want. In addition, as a term indicating a direction, “upper” refers to a direction away from a self-supporting surface in a vertical direction with reference to a cylindrical body mounted on a self-supporting container. “Lower” refers to a direction approaching a self-supporting surface with the cylindrical body as a reference. “Vertical direction” refers to the vertical direction of the cylindrical body, and “circumferential direction” refers to the circumferential direction of the cylindrical body.

(First embodiment)
1 to 3, reference numeral 1 denotes a labeled container including a container 2 and a heat-shrinkable cylindrical label 3 that is externally fitted to the container 2 by heat shrinkage.

The container 2 is not particularly limited as long as the heat-shrinkable cylindrical label 3 can be heat-shrinkable. However, since the heat-shrinkable cylindrical label 3 of the present invention can cut off a partial region X, What has a hollow part dented is preferable.
The container 2 having the recess is not particularly limited. For example, as shown in FIG. 4, the recesses 22 and 23 that are recessed inward on the middle side of the container barrel 21 face both sides of the barrel. The container in which the handle 24 is formed by forming these two recessed parts 22 and 23 which oppose is formed. Further, as shown in FIG. 5, recessed portions 22, 23 recessed inward are formed on one side of the middle portion of the container body portion 21 so as to face both sides of the body portion, and the two recessed portions 22 facing each other. , 23 are penetrated, and a container 2 in which a handle 24 is formed outside the recessed portions 22, 23 penetrated.
In addition, the container 2 having a recessed portion is not limited to the one having the recessed portions 22 and 23 formed for the purpose of forming the handle 24 as described above. The container in which the recessed part more than the location is formed may be sufficient.

The shape of the container 2 is not particularly limited, and may be, for example, a substantially rectangular parallelepiped shape as shown in FIG. 4, a substantially truncated cone shape as shown in FIG. Further, the size of the container 2 is not particularly limited. However, this type of container 2 in which the handle 24 is formed is usually a relatively large container, for example, a volume of 0.5 liters or more, particularly 1 liter or more.
The filling material to be filled in the container 2 is not particularly limited, such as beverages such as juice, sanitary products such as liquid detergent and refill shampoo, pharmaceuticals such as disinfecting alcohol, liquids such as cosmetics, granular detergents, etc. Various fillers such as granular materials are exemplified.

As shown in FIGS. 6 to 8, the heat-shrinkable cylindrical label 3 is bonded to both end portions 32 and 33 of a heat-shrinkable film that can be heat-shrinked at a predetermined temperature (for example, about 80 to 100 ° C.). Has a cylindrical body 31 formed into a cylindrical shape.
The material of the heat-shrinkable film constituting the cylindrical body 31 is not particularly limited as long as it has heat-shrinkability in at least one direction (circumferential direction when formed into a cylindrical shape, hereinafter the same). For example, one type selected from polyester resins such as polyethylene terephthalate, olefin resins such as polypropylene, styrene resins such as polystyrene and styrene-butadiene copolymers, thermoplastic resins such as cyclic olefin resins and vinyl chloride resins. Alternatively, a synthetic resin film made of a mixture of two or more kinds can be used. Moreover, the laminated film by which 2 or more types of films which have heat shrinkability were laminated | stacked may be used, and the laminated film by which heat insulation layers, such as a foamed resin sheet, and other functional layers were laminated | stacked on the film which has heat shrinkability is used. You can also. Among these, those including a polyester film are preferable from the viewpoint of excellent shrinkage characteristics. A polyester-based stretched film having heat shrinkability in one direction is strong in tearing in one direction. However, in the present invention, even if such a film is used, the film is surely and neatly cleaned according to the longitudinal cutting auxiliary line 5. Can be divided.

  A heat-shrinkable film can be obtained by forming into a film by a well-known manufacturing method and extending | stretching. The stretching treatment is usually performed by main stretching at a temperature of about 70 to 110 ° C. at a width of 2.0 to 8.0 times, preferably about 3.0 to 7.0 times. Furthermore, the film may be stretched at a low magnification of 1.5 times or less, for example, in the other direction of the film (longitudinal direction when formed into a cylindrical shape; the same applies hereinafter). The obtained film becomes a uniaxially stretched film or a biaxially stretched film slightly stretched in a direction orthogonal to the main stretch direction. The thickness of the heat-shrinkable film is not particularly limited, but usually about 30 to 80 μm is used.

The heat shrinkage rate of the heat-shrinkable film is not particularly limited as long as it can be adhered to the container 2 by heat shrinkage. Usually, the heat shrinkage rate in one direction (immersed in 90 ° C. warm water for 10 seconds) is Examples are those of about 30% or more, preferably about 40% or more. In addition, the heat-shrinkable film may be slightly heat-shrinked in the other direction, and the heat-shrinkage rate in the other direction of the film (immersed in warm water at 80 ° C. for 10 seconds) is about −3 to 15%. Is exemplified.
However, thermal shrinkage rate (%) = [{(original length in one direction (or other direction)) − (length after immersion in one direction (or other direction))} / (one direction (or other direction) ) Original length)] × 100.

Note that a design printing layer (not shown) such as a trade name, a trademark, and a pattern design is printed on the heat-shrinkable film in a single color or multicolor printing by gravure printing or the like. Thereby, desired design printing is represented on the cylindrical body 31.
The cylindrical body 31 is formed in a cylindrical shape by superimposing one end portion 32 of the heat-shrinkable film on the outer surface of the other end portion 33 so that the main stretching direction of the heat-shrinkable film is the circumferential direction. The center seal portion 9 is formed by bonding the overlapped portion using a solvent or an adhesive.

  The cylindrical body 31 is provided along the vertical cutting auxiliary line 5 extending in the vertical direction, the horizontal cutting auxiliary line 6 connected to the upper and lower ends of the vertical cutting auxiliary line 5 and extending in the circumferential direction, and the vertical cutting auxiliary line 5. And a strip-shaped film thick portion 7 extending in the vertical direction.

Specifically, a pair of left and right vertical cutting auxiliary lines 5 are formed in the plane of the cylindrical body 31 with a predetermined interval in the circumferential direction (among the two vertical cutting auxiliary lines 5 and 5). When viewed from the front, the right side may be referred to as “first vertical cut auxiliary line 51” and the left side may be referred to as “second vertical cut auxiliary line 52”). A pair of upper and lower horizontal cutting auxiliary lines 6 are formed (in the case of the two horizontal cutting auxiliary lines 6, the upper side is called “first horizontal cutting auxiliary line 61” and the lower side is called “second horizontal cutting auxiliary line 62”. There).
The first horizontal cutting auxiliary line 61 is formed so as to span between the upper end of the first vertical cutting auxiliary line 51 and the upper end of the second vertical cutting auxiliary line 52. The second horizontal cutting auxiliary line 62 is formed so as to span between the lower end of the first vertical cutting auxiliary line 51 and the lower end of the second vertical cutting auxiliary line 52.

By separating the cylindrical body 31 (film) in accordance with the first and second vertical cutting auxiliary lines 51, 52 and the first and second horizontal cutting auxiliary lines 61, 62, they are surrounded by the respective cutting auxiliary lines 51,. A partial region X of the broken cylindrical body 31 can be cut out.
The formation positions of the first and second vertical cut auxiliary lines 51 and 52 and the first and second horizontal cut auxiliary lines 61 and 62 are not particularly limited. For example, when the heat-shrinkable cylindrical label 3 of the present invention is attached to the container 2 having the recessed portion 22, the first and second vertical cutting auxiliary lines 51 and 52 and the first and second horizontal cutting auxiliary lines. The first and second vertical cut assist lines 51 and 52 and the first and second horizontal cut assists so that the region surrounded by 61 and 62 (that is, the partial region X) includes the recessed portions 22 and 23 of the container 2. Lines 61 and 62 are preferably formed.
The first vertical cut auxiliary line 51 and the second vertical cut auxiliary line 52 are formed in a straight line parallel to the center seal portion 9. However, the first vertical cutting auxiliary line 51 and the second vertical cutting auxiliary line 52 are not limited to being formed in parallel with the center seal part 9 as long as they extend in the vertical direction. For example, the center seal part 9 may be formed in the vertical direction with a slight inclination with respect to 9. Further, the first vertical cutting auxiliary line 51 and the second vertical cutting auxiliary line 52 may be formed in a non-linear shape (for example, a substantially arc shape extending in the vertical direction, a substantially saw blade shape extending in the vertical direction, etc.). .

Specifically, when the heat-shrinkable cylindrical label 3 of the present invention is attached to the container 2 in which the two recessed portions 22 and 23 are formed, as shown in FIG. 1 and FIG. The first vertical cut assist line 51 is formed so as to substantially coincide with or be positioned in the vicinity of the right edge of the one recessed portion 22 of the container 2 and extend in the vertical direction. On the other hand, the second vertical cutting auxiliary line 52 is formed so as to substantially coincide with or be located in the vicinity of the left edge of the other recess 23 of the container 2 and extend in the vertical direction.
The first horizontal cutting auxiliary line 61 is formed so as to substantially coincide with or be located in the vicinity of the upper edges of the pair of recesses 22 and 23 of the container 2 and extend in the circumferential direction. On the other hand, the second horizontal cutting auxiliary line 62 is formed so as to substantially coincide with or be located in the vicinity of the lower edges of the pair of recesses 22 and 23 of the container 2 and to extend in the circumferential direction.

The vertical cutting auxiliary line 5 and the horizontal cutting auxiliary line 6 are linear portions for facilitating the cutting of the film at the forming portion. Examples of the vertical cutting auxiliary line 5 and the horizontal cutting auxiliary line 6 include a perforation line and a half cut line. The perforation line is a line in which a through hole penetrating in the thickness direction of the film is intermittently engraved like a stitch mark of a sewing needle. The half-cut line is a line in which notched portions cut into a substantially V shape in the thickness direction of the film (without penetrating the film) are continuous. In the present invention, it is preferable to use a perforation line as the vertical cutting auxiliary line 5 and the horizontal cutting auxiliary line 6 because it is easy to form and excellent in film splitting.
Hereinafter, the case where a perforation line is used as the vertical cutting auxiliary line 5 and the horizontal cutting auxiliary line 6 will be described. The vertical cutting auxiliary line 5 is “vertical perforation line 5”, the first vertical cutting auxiliary line 51 is “first vertical perforation line 51”, and the second vertical cutting auxiliary line 52 is “second vertical perforation line 52”. The horizontal cutting auxiliary line 6 is “horizontal perforation line 6”, the first horizontal cutting auxiliary line 61 is “first horizontal perforation line 61”, and the second horizontal cutting auxiliary line 62 is “second horizontal perforation line 62”. And may be described respectively.

The shape of the through-holes of the vertical perforation line 5 and the horizontal perforation line 6 is not particularly limited, and may be any of a circular shape (including an elliptical shape) and an elongated linear shape. The length of each perforation through-hole (diameter when the through-hole is circular, or the length in the longitudinal direction when the through-hole is long and thin) and the length of the non-through portion (adjacent through-hole Is not particularly limited, and can be appropriately designed.
The length of the through hole and the length of the non-penetrating portion of the vertical perforation line 5 are preferably 1: 1 to 2: 1, and more preferably about 2: 1. Specifically, the length of the through hole of the vertical perforation line 5 is preferably 0.5 mm to 2 mm. On the other hand, the length of the non-penetrating portion of the vertical perforation line 5 is preferably 0.5 mm to 1 mm. Especially, it is especially preferable that a through-hole is 2 mm and the length of a non-penetrating part is 1 mm.

If necessary, a part of the through hole of the vertical perforation line 5 may be a longer through hole. For example, you may form the through-hole which exists in the vertical direction center part of the vertical perforation line 5 in length about 10 mm-20 mm. Thus, when the heat-shrinkable cylindrical label 3 is heat-shrinked by forming a part of the through holes of the vertical perforation line 5 longer than the other through-holes, the part of the long through-holes Is pulled in the circumferential direction and opens greatly. For this reason, this opening part becomes an opening start point, and a finger can be inserted from the opening start point and the edge thereof can be easily grasped.
Further, as shown in the figure, the vertical perforation line 5 is not limited to a single line, and two or more lines may be formed adjacent to each other. That is, the first vertical perforation line 51 and / or the second vertical perforation line 52 may be composed of two or more adjacent perforation lines extending in the vertical direction. The two perforations are preferably formed, for example, with an interval of about 1 mm to 4 mm in the circumferential direction, and the through holes and non-through portions of the perforations have a length of about 0.7 mm, respectively. Preferably it is formed.

  On the other hand, the length of the through hole and the length of the non-penetrating portion of the horizontal perforation line 6 are preferably 1: 1 to 2: 1, and more preferably about 2: 1. Specifically, the length of the through hole of the horizontal perforation line 6 is preferably 0.5 mm to 2 mm. On the other hand, the length of the non-penetrating portion of the horizontal perforation line 6 is preferably 0.5 mm to 1 mm.

Next, the film thick portion 7 is a portion where the film thickness is partially formed in the cylindrical body 31. The thick film portion 7 is provided along the first vertical perforation line 51 and the second vertical perforation line 52, respectively.
The film thick part 7 is composed of, for example, a part in which two or more films are overlapped. The thick film portion 7 can be configured, for example, by attaching a tear tape 8 to the inner surface of the cylindrical body 31. The thick film portion 7 can also be configured by using the center seal portion 9 of the cylindrical body 31.
Hereinafter, the film thick part 7 provided along the first vertical perforation line 51 is referred to as “first film thick part 71”, and the film thick part 7 provided along the second vertical perforation line 52 is referred to as “ The second film thick part 72 "may be described as the case.

The first film thick portion 71 is provided to extend in the vertical direction along the first vertical perforation line 51 on the side opposite to the partial region X with respect to the first vertical perforation line 51. . That is, the first film thick portion 71 is provided on the non-cut region side, substantially parallel to the first vertical perforation line 51 and at least from the upper end to the lower end of the first vertical perforation line 51.
The side opposite to the partial region X is a region of the cylindrical body 31 that is not intentionally cut off and removed, and hereinafter, the side opposite to the partial region may be referred to as a “non-cut region side”.

In the present embodiment, the tear tape 8 is used as the first film thick portion 71.
As the tear tape 8, for example, a belt-like film having straight side edges 8a is used. The material of the tear tape 8 is not particularly limited, and any resin film can be used similarly to the film constituting the cylindrical body 31. The tear tape 8 may be a film that can be heat-shrinked in the circumferential direction, but it is preferable to use a non-heat-shrinkable film (a film that does not heat-shrink at the heat-shrinking temperature of the cylindrical body 31). This is because when the tear tape 8 is thermally shrunk in the circumferential direction, the through-holes of the adjacent vertical perforation lines 5 are pulled in the circumferential direction and easily opened greatly.

  As shown in FIG. 8, the tear tape 8 is attached along the first vertical perforation line 51 with its linear side edge 8 a positioned in the vicinity of the first vertical perforation line 51. The side edge 8a of the tear tape 8 is preferably arranged as close as possible to the first vertical perforation line 51. For example, the distance between the side edge 8a of the tear tape 8 and the first vertical perforation line 51 is 4 mm or less, preferably 3 mm or less.

As a method of attaching the tear tape 8 to the inner surface of the cylindrical body 31, for example, an adhesive can be used. Further, when the tear tape 8 and the cylindrical body 31 are made of a material that can be bonded with a solvent, the tear tape 8 and the cylindrical body 31 can be bonded to the cylindrical body 31 with a solvent.
The width (the length in the circumferential direction) of the tear tape 8 is not particularly limited, but a tape of about 2 mm to 7 mm is usually used.

The tear tape 8 is attached from the upper edge to the lower edge of the cylindrical body 31. The present invention provides a first film thick portion 71 on the non-cut region side with respect to the first vertical perforation line 51 to divide a part of the cylindrical body 31 according to the first vertical perforation line 51. In addition, cracks are prevented from occurring on the non-cut region side. For this reason, the film thick part 7 should just be provided corresponding to the upper end from the upper end of the vertical cut auxiliary | assistant line 5, but attaching the tear tape 8 only to the longitudinal direction middle part of the cylindrical body 31 is manufacturing. It is complicated. Furthermore, it is preferable for the said objective that the film thick part 7 is provided longer upwards and / or downwards rather than the upper end and / or lower end of the vertical cut auxiliary line 5. FIG.
For this reason, the tear tape 8 is preferably attached from the upper edge to the lower edge of the cylindrical body 31.

  On the other hand, the second film thick portion 72 is provided to extend in the vertical direction along the second vertical perforation line 52 on the side opposite to the partial region X with respect to the second vertical perforation line 52. Yes. That is, the second film thick portion 72 is provided on the non-cut region side, substantially parallel to the second vertical perforation line 52 and at least from the upper end to the lower end of the first vertical perforation line 51.

In the present embodiment, the center seal portion 9 is used as the second film thick portion 72.
As described above, the center seal portion 9 is an overlapping bonding portion of the one end portion 32 and the other end portion 33 of the heat-shrinkable film in order to form the cylindrical body 31.
The order in which the one side end portion 32 and the other side end portion 33 overlap in the center seal portion 9 is not particularly limited, and any side end portions 32 and 33 are located on the outer surface side of the cylindrical body 31. Good. In particular, the center seal portion is formed by superimposing the side end portions 32 and 33 of the heat-shrinkable film so that the edge 32a of the one side end portion 32 located outside the cylindrical body 31 is close to the second vertical perforation line 52. 9 is preferably formed. When the center seal portion 9 is formed, the edge portion 33a of the other side end portion 33 located on the inner side is normally extended as a margin of a few mm that is not bonded, as shown in FIG. This is because it causes trouble when dividing according to the second vertical perforation line 52.

An edge 32a of the one end portion 32 of the center seal portion 9 extends linearly in the vertical direction, and a second vertical perforation line 52 is formed in the vicinity of the edge. The edge 32 a of the one side end portion 32 of the center seal portion 9 is preferably as close as possible to the second vertical perforation line 52. For example, the distance between the edge 32a of the one end portion 32 of the center seal portion 9 and the second vertical perforation line 52 is 5 mm or less, preferably 4 mm or less.
The width (the length in the circumferential direction) of the center seal portion 9 is not particularly limited, but is usually formed to about 3 mm to 10 mm.

In addition, in order to make it easy to remove the heat-shrinkable cylindrical label 3 from the container 2 in order to recycle the container 2, the cylindrical body 31 is formed with a longitudinal opening auxiliary line 4 extending in the vertical direction.
In the present embodiment, the vertical opening auxiliary line 4 is provided continuously to the first vertical perforation line 51. Specifically, the longitudinal opening auxiliary line 4 is formed from the first longitudinal opening auxiliary line 41 formed from the upper edge of the cylindrical body 31 to the upper end of the first vertical perforation line 51 and the lower end of the first vertical perforation line 51. A second longitudinal opening assisting line 42 formed over the lower edge of the cylindrical body 31.
Therefore, the longitudinal opening auxiliary line 4 is connected to the first vertical perforation line 51 at the middle in the vertical direction.
The vertical opening auxiliary line 4 may be provided continuously with the upper and lower ends of the second vertical perforation line 52, and the vertical opening auxiliary line 4 includes the first vertical perforation line 51 and the second vertical perforation line. 52 (in this case, two longitudinal opening auxiliary lines 4 extending in the upper and lower edges are provided at predetermined intervals in the circumferential direction).

However, the vertical opening auxiliary line 4 is not connected to the first vertical perforation line 51 and the second vertical perforation line 52, and is formed independently in the vertical direction from the upper edge to the lower edge of the cylindrical body 31. May be.
By providing the vertical opening auxiliary line 4 in this way, the entire heat-shrinkable cylindrical label 3 can be divided in the vertical direction and removed from the container 2 after use.

The said heat-shrinkable cylindrical label 3 can be manufactured as follows, for example.
A long heat-shrinkable film original (the main heat-shrink direction is the TD direction) and a long tear tape with an adhesive applied to the back surface are prepared. This tear tape is affixed to a predetermined position of the film film to be fed out.
Next, using a perforation forming device (such as a Thomson blade or a rotary blade), two longitudinal perforations (longitudinal cutting auxiliary line and longitudinal opening auxiliary line) on the original film with tear tape attached in the longitudinal direction And a perforation (transverse cutting auxiliary line) in a direction orthogonal to the longitudinal direction is formed between the perforations in the longitudinal direction. When forming the perforations, cuts for dividing the tear tape are also engraved at the same time.

Thereafter, the heat-shrinkable film original fabric is overlapped on both sides of the heat-shrinkable film original fabric so that the main heat-shrink direction is the circumferential direction, and the overlapped portion is put through a solvent (or adhesive). A center seal portion is bonded to extend in the longitudinal direction.
Thus, the cylindrical label original fabric which the said heat-shrinkable cylindrical label 3 connected continuously can be produced. The cylindrical label original is once wound up in a roll and loaded into a labeler. In the labeler, after the cylindrical label original fabric is cut into a predetermined length to form the heat-shrinkable cylindrical label 3, the partial region X of the heat-shrinkable cylindrical label 3 is formed into the recessed portions 22 and 23 of the container 2. The heat-shrinkable cylindrical label 3 is heated while fitting to the above.
Thereby, the labeled container 1 as shown in FIGS. 1-3 can be obtained.

In use, the labeled container 1 divides a part of the cylindrical body 31 according to the first vertical perforation line 51 of the heat-shrinkable cylindrical label 3 as shown in FIG.
When a part of the through hole of the first vertical perforation line 51 is cut long and a large opening part (opening opening) is formed in a part of the first vertical perforation line 51, a finger is placed on that part. The cylindrical body 31 is divided according to the first vertical perforations 51 by inserting and pulling out the film so as to be partly turned to the region X side.
In the heat-shrinkable cylindrical label 3 of the present invention, the first film thick portion 71 is formed along the first vertical perforation line 51 on the partial region X side. The provided part is harder to cut than the other parts. Therefore, by rolling the film, the cylindrical body 31 can be divided along the first vertical perforation line 51 (the side edge 8a of the first thick film portion 71) without causing a crack on the non-cut region side. .
In particular, since the side edge 8a of the first film thick portion 71 is provided close to and in parallel with the first vertical perforation line 51, the dividing edge generated by dividing at the first vertical perforation line 51 is It becomes a beautiful straight streak that is almost straight.

Further, when the first vertical perforation line 51 is divided to the upper and lower ends, the cylindrical body 31 can be divided from the cut 81 according to the first and second horizontal perforation lines 61 and 62, and finally, divided along the second vertical perforation line 52. By doing so, the partial region X can be completely cut off from the cylindrical body 31.
The second vertical perforation line 52, which is the cut-off end portion of the partial region X, is provided with a second film thick portion 72 on the non-cut region side. For this reason, when cutting according to the 2nd vertical perforation line 52, the cylindrical body 3 can be parted according to the 2nd vertical perforation line 52, without a crack arising in the non-cutting area side.
In the labeled container 1 from which the partial region X is cut, a window portion is formed in the heat-shrinkable cylindrical label 3.

The heat-shrinkable cylindrical label 3 of the present invention is provided with first and second thick film portions 71 and 72 along the first and second vertical perforation lines 51 and 52 on the non-cut region side. Therefore, the edge part of the window part formed after cutting out the partial region X becomes a beautiful line mark. For this reason, there is no fear that the edge part of the window part will be drowned greatly, and the appearance of the window part will be good.
In particular, when the partial region X of the heat-shrinkable cylindrical label 3 is attached so as to correspond to the concave portion 22 of the container 2, the partial region X corresponding to the concave portion 22 is greatly contracted during thermal contraction. Therefore, contraction stress acts strongly on both sides in the circumferential direction of the partial region X, and the design on both sides tends to be distorted. In this respect, the heat-shrinkable cylindrical label 3 of the present invention is provided with the film thick portion 7 on the non-cut region side with respect to the vertical perforation line 5, so that the shrinkage stress of the partial region X is , And is blocked by the thick film portion 7. For this reason, the shrinkage stress of the partial region X is unlikely to act on the non-cut region on the opposite side across the thick film portion 7, and the design of the non-cut region can be prevented from being distorted.
And in the container 1 with a label in which the window part was formed in the heat-shrinkable cylindrical label 3, since the recessed parts 22 and 23 of the container 2 are exposed from this window part, putting a finger into this recessed part 22 and 23 The handle 24 can be securely grasped.

(Second Embodiment)
The second embodiment relates to the heat-shrinkable cylindrical label 3 in which a heat-sensitive adhesive is provided on the inner surface of the cylindrical body 31.
Hereinafter, in the present embodiment, configurations and effects different from those of the first embodiment will be mainly described, descriptions of the same configurations and effects as those of the first embodiment will be omitted, and terms and symbols will be used. The following third to seventh embodiments will also be described in the same manner, and descriptions of the same configurations and effects as those of the embodiments will be omitted, and terms and symbols will be used.

As shown in FIG. 10, the heat-shrinkable cylindrical label 3 of the present embodiment is provided with a heat-sensitive adhesive portion 10 on the inner surface of the cylindrical body 31 so as to surround a partial region X of the cylindrical body 31. .
Specifically, the heat-sensitive adhesive portion 10 is provided with a first heat-sensitive adhesive portion extending in the vertical direction along the first vertical perforation line 51 on the non-cut region side with respect to the first vertical perforation line 51. The adhesive part 11, the second heat-sensitive adhesive part 12 provided extending in the vertical direction along the second vertical perforation line 52 on the non-cut region side with respect to the second vertical perforation line 52, With reference to the first horizontal perforation line 61, on the non-cutting region side, a third heat-sensitive adhesive portion 13 provided extending in the circumferential direction along the first horizontal perforation line 61 and a second horizontal perforation line 62 are provided. And a fourth heat-sensitive adhesive portion 14 provided extending in the circumferential direction along the second horizontal perforation line 62 on the non-cut region side as a reference. The first to fourth heat-sensitive adhesive portions 11 to 14 are provided on the inner surface of the cylindrical body 31 by applying a heat-sensitive adhesive in a band shape at the above position.

  The heat-sensitive adhesive is an adhesive that does not exhibit adhesiveness at room temperature and can develop adhesiveness when heated. Among them, the heat-shrinkable temperature of the heat-shrinkable cylindrical label 3 (for example, about 80 to 100 ° C.) It is preferable to use a material that exhibits adhesive strength. If a heat-sensitive adhesive having such a temperature is used, the heat-shrinkable cylindrical label 3 can be activated by heat applied to heat-shrink and adhere to the container 2.

As the heat-sensitive adhesive, for example, a delayed tack type heat-sensitive adhesive, a part coat type heat-sensitive adhesive, a hot-melt type adhesive, or the like can be used.
A delayed tack-type heat-sensitive adhesive does not exhibit adhesiveness at room temperature, is activated by heating to exhibit adhesiveness, and persists for a long time after cooling, and is applied by printing such as gravure coating. It is a workable adhesive. Examples of the delayed tack type heat-sensitive adhesive include an emulsion type in which a tackifier and a solid plasticizer are blended with a base resin such as an ethylene-vinyl acetate copolymer, a vinyl acetate-acrylic acid ester copolymer, and a synthetic rubber. The thing etc. are illustrated.
The part coat type heat-sensitive adhesive does not show adhesiveness at room temperature, but shows adhesiveness by heating. For example, a heat-adhesive resin such as ethylene-vinyl acetate copolymer and a tackifier are dissolved in an organic solvent or the like. The dispersed solution is an adhesive that can be applied by printing such as gravure coating, and is used after drying after coating.
The hot-melt adhesive does not exhibit adhesiveness at room temperature, and can be bonded by heating, and is an adhesive that can be applied by heating and melting. Examples of hot melt adhesives include additives such as tackifiers to base resins such as ethylene resins such as ethylene-vinyl acetate copolymer and ethylene acrylic acid copolymer, and styrene-butadiene block copolymers. What was mix | blended is illustrated.

  In the present invention, since it can be easily applied in a desired range, it is preferable to use a heat-sensitive adhesive that can be applied by printing, such as the delayed tack-type heat-sensitive adhesive or the part-coat-type heat-sensitive adhesive. In particular, it is more preferable to use a delayed tack type heat sensitive adhesive whose adhesiveness is maintained for a long time.

  In the heat-shrinkable cylindrical label 3 according to this embodiment, the heat-sensitive adhesive is activated by heat when heat-shrinking and mounting the container 2, and the heat-sensitive adhesive portion 10 adheres to the outer surface of the container 2. In addition, you may use together the heating apparatus for heating a heat sensitive adhesive in a spot manner as needed.

  In the heat-shrinkable cylindrical label 3 of the present embodiment, the edge portion of the window portion produced after the partial region X is cut out according to the respective cut auxiliary lines 5 and 6 is bonded to the container 2 via the heat-sensitive adhesive portion 10. It becomes. Accordingly, since the edge of the window can be prevented from curling, the heat-shrinkable cylindrical label 3 is particularly preferable in terms of appearance without causing design distortion or the like.

  In the present embodiment, the heat-sensitive adhesive portion 10 is provided with the first to fourth heat-sensitive adhesive portions 11 to 14 so as to surround the partial region X, but the present invention is not limited to this. -At least 1 place chosen from the 4th heat sensitive adhesion parts 11-14 should just be provided. However, it is preferable that at least the first heat-sensitive adhesive portion 11 and the second heat-sensitive adhesive portion 12 are provided because the vertical edge (parting edge) of the edge portion of the window portion tends to be bent. .

In the present embodiment, since the edge of the window portion can be prevented from curling, for example, as shown in FIG. 11, the first vertical perforation line 51 and the second vertical perforation line 52 are formed on the cylindrical body 31. This is particularly effective when formed from an edge. That is, this heat-shrinkable cylindrical label 3 is an aspect in which the first horizontal perforation line 61 is not formed.
In the heat-shrinkable cylindrical label 3, when the partial region X is cut out, the upper portion of the cylindrical body 31 is completely divided into left and right, and therefore, the heat-shrinkable cylindrical label 3 tends to bend at the upper edge portion of the window portion. In this respect, the dripping can be prevented by providing the heat-sensitive adhesive portion 10 as in the present embodiment.

When the film thick portion 7 is provided on the partial region X side as in this embodiment, the film thick portion 7 (for example, the tear tape 8) is provided from the upper edge to the lower edge of the cylindrical body 31. For example, when the partial region X is cut out with the first vertical perforation line 51 as the opening start point, the first and second horizontal perforation lines are due to the presence of the first film thick portion 71 provided on the partial region X side. Inconvenient in that it cannot be cut in the circumferential direction according to 61,62.
For this reason, in this embodiment, the cut | interruption 81 extended in the circumferential direction is formed in the longitudinal direction middle part of the 1st film thick part 71 provided in the partial region X. The cut 81 corresponds to the upper end of the first vertical perforation line 51 (the continuous portion of the first horizontal perforation line 61) and the lower end of the first vertical perforation line 51 (the continuous portion of the second horizontal perforation line 62). Are formed respectively. Accordingly, the cuts 81, 81 correspond to a through hole at one end of the first horizontal perforation line 61 and a through hole at one end of the second horizontal perforation line 62.

By forming the cut 81, the tear tape 8 provided from the upper edge to the lower edge of the cylindrical body 31 is divided in the circumferential direction. In this manner, a substantially independent tear tape 8 can be formed between the upper end and the lower end of the first vertical perforation line 51.
The cut 81 may be formed so as to completely divide the tear tape 8 vertically, or may be partially cut from one side edge of the tear tape 8 to a middle portion in the circumferential direction. Such incompletely divided cuts 81 are preferably formed from the side edges on the first vertical perforation line 51 side of both side edges of the tear tape 8.
Similarly, the upper end of the second vertical perforation line 52 (continuous connection of the first horizontal perforation line 61) is also applied to the second film thick portion 72 on the partial region X side provided along the second vertical perforation line 52. Part) and the lower end of the second vertical perforation line 52 (the connected part of the second horizontal perforation line 62), the cuts 81 are preferably formed respectively.

Of the tear tapes 8 divided by the first vertical perforation line 51 and the second vertical perforation line 52, the tear tape 8 positioned on the partial region X side is the first vertical perforation line 51 and the second vertical perforation line. Upper and lower cuts 81 are formed at the upper and lower ends of 52.

The heat-shrinkable cylindrical label 3 according to this modification is a preferable embodiment because the work for applying the tear tape 8 can be reduced. That is, in the example shown in FIG. 13, four tear tapes 8 must be affixed, but in the case of this modification, the same effect as described above can be achieved by affixing two tear tapes 8.
In the present embodiment and the modification, in order to easily divide the tear tape 8 into two by forming the first vertical perforation line 51 (or / and the second vertical perforation line 52), It is preferable to use a film having tearability in the longitudinal direction as the tear tape 8.

In the present embodiment and the modification, the thick film portion 7 is formed on both sides of the first vertical perforation line 51 and the second vertical perforation line 52, but either one of the vertical perforation lines 51 , 52 may be sufficient.
Further, in the present embodiment and the modification, the film thick part 7 is constituted by the tear tape 8, but one of the film thick parts 7 can be constituted by the center seal part 9. .
