Description

  The present invention relates to a rectangular container with a cylindrical label in which at least two easy-cleavage lines such as perforations for label cutting are formed, and a continuous cylindrical label.

Conventionally, a labeled container in which a label is attached to various containers such as a beverage container has been widely used. Among them, there is a rectangular container with a cylindrical label in which a heat-shrinkable cylindrical label is attached to a rectangular container made of synthetic resin having a horizontal cross section of a substantially square shape or the like. Specifically, in this type of container, for example, as shown in JP-A No. 2002-196777, the connecting corners of four panel surfaces are chamfered, and the corner surface is narrower than the panel surface. Cylindrical labels are mounted by heat shrinking on square containers with four barrels, and full shrink type, semi-full shrink type, and half shrink type are known depending on the label mounting mode. It has been. In such a cylindrical label, as shown in FIG. 1 of the publication, a single perforation is formed in the longitudinal (vertical) direction in a region corresponding to the corner surface of the rectangular container in order to divide the label during recycling. ing.
However, there is a problem that it is difficult to divide the label with only one perforation.
Therefore, a cylindrical label in which two perforations are formed in the longitudinal direction is also known.

However, the corner surface of the rectangular container has a relatively narrow width. Therefore, two perforations are formed in a region corresponding to one corner surface of the cylindrical label attached to this type of rectangular container. Is difficult to manufacture. Also, even if two perforations are formed in the area corresponding to one corner surface, the interval between the two perforations must be narrowed, and the label is divided by pinching between the perforations. Is difficult. In particular, in the case of the full shrink type that is mounted even on the neck portion having a very small diameter, the upper edge portion of the label is greatly contracted, so that the interval between the two perforations is substantially eliminated.
In this regard, it is conceivable to form one of the two perforations in a region corresponding to the corner surface and the other one in a region corresponding to the panel surface. However, the panel surface of the square container is relatively flexible, and if a perforation is formed in a region corresponding to the panel surface, the label may be broken from the perforation due to an impact applied to the container due to dropping or the like. There is.

Japanese Patent Application Laid-Open No. 2002-196677 [0002] to [0004], FIG. 1 and FIGS.

  Then, this invention makes it a subject to provide the square container with a cylindrical label which can prevent the fracture | rupture of a label by impacts, such as dropping, and a cylindrical label continuous body, making it easy to divide a label.

  As a first means for solving the above-mentioned problem, the present invention provides a body portion in which a connecting corner portion of adjacent panel surfaces is chamfered and a corner surface narrower than the panel surface is formed at the corner portion. A rectangular container with a cylindrical label, and a heat-shrinkable cylindrical label attached to the barrel, and an easy-cleavage line for label separation is formed on the cylindrical label. In addition, there is provided a rectangular container with a cylindrical label in which easy-cleavage lines of the cylindrical label are respectively formed in regions corresponding to the corner surfaces located on both sides of one panel surface.

Since the said square container with a cylindrical label has the easy-cleavage line for label parting in the area | region corresponding to each corner surface located in the both sides of one panel surface, respectively, these two easy-cleavage lines The interval is sufficiently secured. Therefore, the label can be easily divided by picking and tearing the upper edge of the cylindrical label between the two easy-cleavage lines.
In addition, since these easy-cleavage lines are provided in the region corresponding to the corner surface, the label is not easily broken even if an impact is applied to the container, and does not cause a decrease in label strength.

  Further, the second means of the present invention is a cylindrical label continuous body in which two folds facing each other are formed in the longitudinal direction by folding a cylindrical body made of a flexible film into a flat shape, An easy-cleavage line for separating the label is formed in the longitudinal direction at a position near at least one of the two folds, and further, this fold is rotated 90 degrees in the circumferential direction of the cylindrical body. Provided is a cylindrical label continuous body in which an easy-cleavage line for label division is formed in the longitudinal direction in the vicinity of the position.

In general, a flat cylindrical label continuous body is refolded so that two folds are overlapped before being inserted into a container, thereby rotating 90 degrees in the circumferential direction of the cylindrical body from the folds. Two refolds are formed at each position. By performing this refolding, it becomes easy to bend at the fold and the refold, and the cylindrical label can be opened in a square shape when being inserted into the container.
In the cylindrical label continuous body of the present invention, an easy-cleavage line for label separation is formed in the longitudinal direction in the vicinity of one fold, and the position at a position rotated 90 degrees from the fold in the circumferential direction of the cylindrical body. Since an easy-cleavage line for label separation is formed in the longitudinal direction in the vicinity, when the folding is performed as described above, the easy-cleavage lines are respectively located in the vicinity of the fold and the refold. Such a cylindrical label is opened in a quadrangular shape, and each side center portion between the crease and the refold line faces each panel surface of the container body portion where the corner surface is formed between the four panel surfaces. By inserting the cylindrical label and causing thermal contraction, it is possible to manufacture a rectangular container with a cylindrical label in which easy-cleavage lines are respectively arranged in the corresponding regions of both corner surfaces located on both sides of one panel surface. .

  Further, the third means of the present invention is a cylindrical label continuous body in which two folds facing each other are formed in the longitudinal direction by folding a cylindrical body made of a flexible film into a flat shape, Rotated 45 degrees to both sides in the circumferential direction of the cylindrical body with reference to a position rotated 90 degrees in the circumferential direction of the cylindrical body from at least one of the two folds Provided is a cylindrical label continuous body in which an easy-cleavage line for label separation is formed in the longitudinal direction at or near each position.

  Such a continuous cylindrical label body of the present invention is 45 degrees toward both sides in the circumferential direction of the cylindrical body with reference to one fold line or a position rotated 90 degrees from the one fold line in the circumferential direction of the cylindrical body. Since an easy-cleavage line for label separation is formed in the longitudinal direction at each rotated position or in the vicinity thereof, when refolding is performed as described above, each of the fold line and the refold line is easily moved to the vicinity of the center. The cleavage line will be located. By opening the cylindrical label in a quadrangular shape and inserting the cylindrical label so that the center of each side between the crease and the refold line faces each corner surface of the container body portion, and heat shrinking, It is possible to manufacture a rectangular container with a cylindrical label in which easy-cleavage lines are respectively arranged in the corresponding areas of the corner surfaces located on both sides of the panel surface.

The rectangular container with a cylindrical label of the present invention can hold the upper edge (or lower edge) of the cylindrical label and divide the label along two easy-cleavage lines. Accordingly, it is possible to provide a rectangular container with a cylindrical label that can be easily recycled. In addition, since the easy-cleavage line is provided in the corresponding region of the corner surface of the rectangular container, there is no possibility that the label is inadvertently broken from the easy-cleavage line even if an impact or the like is applied to the container.
In addition, the cylindrical label continuous body of the present invention can easily produce the rectangular container with the cylindrical label, which is easy to divide the label and does not inadvertently break by performing the folding operation when the label is attached. .

Hereinafter, the present invention will be specifically described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a rectangular container 2 having a barrel portion 22 in which a connecting corner portion of an adjacent panel surface 5 is chamfered and a narrow corner surface 6 is formed at the connecting corner portion. The cylindrical container with a cylindrical label provided with the cylindrical label 3 with which this container trunk | drum was mounted | worn by heat shrink is shown.

Specifically, as shown in FIG. 2, for example, the rectangular container 2 is formed with a bottom surface portion 21, a hollow rectangular body portion 22 that follows this, and a shoulder portion 23 that gradually narrows from the body portion 22. Furthermore, a neck portion 24 extending above the shoulder portion 23 is formed, and a screw cap 25 for opening and closing the spout is attached to the neck portion 24. The horizontal cross-sectional shape of the container body 22 is formed in a substantially square shape such as a substantially square shape. Specifically, the container body portion 22 mainly includes a basic mode in which four panel surfaces 5 are combined in an orthogonal direction, and adjacent panels are chamfered so as to chamfer a right angle portion generated at a connection portion of the adjacent panel surfaces 5. A corner surface 6 is formed between the surfaces 5. The corner surface 6 is narrower than the panel surface 5 (the length in the circumferential direction of the body portion 22), and is formed integrally with the panel surface 5 at an angle of 45 degrees. The panel surface 5 and the corner surface 6 are formed up to the shoulder portion 23. In the figure, reference numeral 51 denotes a rib formed on the panel surface 5, which protrudes inward. The rib 51, together with the portion surrounded by the rib 51, can respond to changes in the internal pressure of the container.
The material of the container 2 is not particularly limited, and any conventionally known material can be used. However, it is particularly effective to apply the present invention to a flexible container. As a flexible container, a relatively thin synthetic resin container such as a polyethylene terephthalate container is generally exemplified.

Next, the cylindrical label 3 includes a cylindrical body 32 in which both end portions of a flexible flexible label base material are overlapped to form a center seal portion 31.
The cylindrical label 3 is not particularly limited as long as it is formed of a heat-shrinkable film. For example, a polyester resin such as polyethylene terephthalate, an olefin resin such as polypropylene, and a styrene resin such as a styrene-butadiene copolymer. A heat-shrinkable film selected from a thermoplastic resin film such as a cyclic olefin-based resin and a vinyl chloride-based resin, a foamed resin sheet, and the like, or a laminated film of these, or a heat-shrinkable film and another functional film. Examples include laminated films. For the film, a film that heat-shrinks greatly in the width direction (circumferential direction when a cylindrical label is used) is used, and in addition, a film that slightly heat-shrinks in the vertical direction (direction perpendicular to the width direction) is used. You can also. The embodiment shown in FIG. 1 is a full shrink type that is attached to the upper end of the neck 24 of the container 2, so that the cylindrical label 3 has a thermal shrinkage rate in the circumferential direction (10% in 90 ° C. warm water). (Second immersion) is, for example, 50% or more, preferably 60% or more. Further, the heat shrinkage rate in the vertical direction is 0 to 10%, preferably about 0 to 6%. Although not particularly illustrated, design printing for displaying a product name or the like is performed on the back surface or the front surface of the cylindrical label 3.

  Furthermore, the cylindrical label 3 is formed with two perforations 7 and 7 (easy-cleavage lines) for separating the labels in the longitudinal direction. Each perforation 7, 7 is formed up to the upper and lower edges of the cylindrical label 3. One of the two perforations 7, 7 is formed substantially parallel to the position in the vicinity of the center seal portion 31. When the cylindrical label 3 is attached to the container 2 in a state where the one perforation 7 is positioned in a region corresponding to the corner surface 6, the other perforation 7 has the same panel surface 5 ′ as the corner surface 6. It is formed so as to be located in a region corresponding to the sandwiched corner surface 6. Accordingly, the two perforations 7 and 7 are respectively formed in regions corresponding to the corner surfaces 6 and 6 positioned on both sides of the one panel surface 5 ′, and the two perforations 7 and 7 are formed. A center seal portion 31 is disposed between the two.

As long as the two perforations 7 and 7 are formed within the range of the corresponding region of the corner surface 6 as described above, both of the two perforations 7 and 7 are one panel surface. It is preferable that it is formed closer to 5 ′.
Specifically, the two perforations 7 and 7 are formed at the outer side formed between the other panel surface 5 ″ and the corner surfaces 6 and 6, as shown in FIG. An embodiment in which two perforations 7 and 7 are formed at positions along the obtuse angle portions 22a and 22a, respectively, along the central portion 22b of both corner surfaces 6 and 6, as shown in FIG. An inner obtuse angle portion formed between one panel surface 5 ′ and both corner surfaces 6 and 6, as shown in FIG. 22c, in a form in which two perforations 7, 7 are formed at positions along 22c, between the outer obtuse angle portion 22a and the central portion 22b of the corner surface 6 as shown in FIG. In a form in which two perforations 7 and 7 are formed at a position corresponding to, as shown in FIG. In a mode in which two perforations 7 and 7 are formed at a position corresponding to between the central portion 22b and the inner obtuse angle portion 22c, and in addition, although not particularly illustrated, two at appropriate positions selected from these For example, a mode in which the perforations 7 and 7 are respectively formed is shown, however, in FIGS. The center seal portion 31 formed in the region is not shown.

Among these, since the interval between the two perforations 7 and 7 is relatively narrow and the label can be divided relatively easily, a position corresponding to the center portion 22b of the corner surface 6 and the inner obtuse angle portion 22c. Moreover, it is preferable that two perforations 7, 7 are formed. Furthermore, in order to prevent fraying and breakage from the perforation forming part during transportation and storage, it corresponds between the central part 22b of the corner surface 6 and the inner obtuse angle part 22c excluding the position corresponding to the inner obtuse angle part 22c. More preferably, two perforations 7, 7 are formed at the positions. Further, in order to divide the label 3 between the two perforations 7, 7, it is preferable that the center seal portion 31 is located between the two perforations 7, 7.
The perforation 7 is formed of a line in which a hole portion and a non-hole portion that are formed by a perforation needle are continuously connected. The distance between the hole and the non-hole is designed in consideration of the strength of the label 3 and the ease of separation. For example, when the label is composed of a polystyrene resin film that is relatively easy to tear in the vertical direction. The hole portion: non-hole portion is preferably formed with a length ratio of about 0.5: 3.5 to 0.7: 2.1. The length of the hole is about 0.5 to 2 mm.
In addition, if at least the perforations 7 and 7 are respectively formed on the corner surfaces 6 and 6 on both sides of the one panel surface 5 ′, the perforations 7 and 7 are formed in the corresponding regions of the other corner surfaces 6. May be formed.

Here, the two perforations 7 and 7 in the cylindrical label 3 before being attached to the container 2 are appropriately designed according to the width of the panel surface 5 and the corner surface 6 of the container 2. is there. For example, if the width of the panel surface 5 is “X” and the width of the corner surface 6 is “Y”, the interval W in the circumferential direction of the two perforations 7 and 7 satisfies the following relational expression. Two perforations 7 and 7 may be formed.
{X / (4X + 4Y)} × circumferential length of cylindrical label ≦ interval of two perforations W ≦ {(X + 2Y) / (4X + 4Y)} × circumferential length of cylindrical label.

The cylindrical label-attached rectangular container 1 is formed with perforations 7 and 7 for label division in regions corresponding to the corner surfaces 6 and 6 located on both sides of one panel surface 5 ′. Therefore, the interval between the perforations 7 and 7 is wide, and as shown in FIG. 1, even if the cylindrical label 3 is attached to the container neck 24, the gap between the two perforations 7 and 7 can be grasped by hand. Can do. Therefore, the label 3 can be easily divided along the perforations 7 and 7 by picking this portion and peeling off the cylindrical label 3.
Further, since these perforations 7 are not formed in the region corresponding to the panel surface 5, even if a drop impact or the like is applied to the container, the label 3 is difficult to break from the perforation 7 as a starting point. Has the same strength as a conventional cylindrical label formed on the corner surface.

Next, the manufacturing method and mounting method of the cylindrical label 3 will be described.
In general, the cylindrical label 3 is obtained by cutting the cylindrical label continuous body formed with the center seal portion into a predetermined length by adhering both side ends of the long base material. The rectangular label 1 with the cylindrical label is manufactured by inserting and inserting the label 3 so that the center seal portion 31 faces the corner surface 6 of the rectangular container 2 and thermally contracting it.

Specifically, as shown in FIG. 4A, the base material 100 has a position in the vicinity of a portion 101 where the center seal portion 31 is to be formed and a position in the vicinity of a portion where a refold line 106 which will be described later is formed. The first perforation 7 'is formed in the longitudinal direction. Further, when formed in a cylindrical shape, the second perforation 7 ″ is located at a position that is a predetermined distance from the first perforation 7 ′ (interval W between the two perforations 7, 7). Is formed.
A cylindrical label continuous body 102 made of a cylindrical body is formed by stacking the center seals on both side ends of the base material 100. As shown in FIG. 4 (b), the cylindrical label continuous body 102 is formed to have two folds 104 facing each other by being folded in a flat shape so that the inner surfaces overlap each other.
Specifically, the cylindrical label continuous body 102 has a center portion in the width direction (a position rotated 90 degrees in the circumferential direction of the cylindrical body with respect to the one fold line 104) when the flat shape is formed. It is folded so as to be substantially coincident with the inner edge 31a of 31 or between the inner edge 31a and the first perforation 7 '. Further, the second perforation 7 ″ does not coincide with the fold line 104 and is folded so as to be in the vicinity of the fold line 104 (for example, a position displaced about 2 mm from the fold line 104 in the circumferential direction).
Accordingly, in the flat cylindrical label continuous body 102, the second fold line 7 ″ is provided in the vicinity of one fold line 104, and the cylindrical continuum body 102 is rotated 90 degrees in the circumferential direction of the cylindrical body from the fold line 104. The first perforation 7 ′ is provided in the vicinity.

The flat cylindrical label continuous body 102 is wound into a roll and loaded into a labeler for mounting on a container.
In a labeler (not shown), as shown in FIG. 5, the cylindrical label continuous body 102 is pulled out from the roll, and the flat continuous body 102 is opened to overlap the two folds 104 and 104. Thus, it is flattened again and refolding is performed. By such refolding, two refolds 105 are respectively formed at positions rotated from the two folds 104 by 90 degrees in the circumferential direction of the cylindrical body. Note that the first perforation 7 ′ is located at a position near the refold line 105 (for example, a position displaced about 2 mm from the refold line 105 in the circumferential direction).

  Next, the refolded tubular label continuous body 102 is cut at a predetermined length to produce the tubular label 3. And by opening this before inserting in the container 2, as shown to Fig.6 (a), as shown to Fig.6 (a), the cylindrical label 3 is substantially square-shaped opening part bent in each fold 104 and the refold 105. Arise. In this state, as shown in FIG. 4B, the cylindrical label 3 is arranged such that the center of the four sides between each fold line 104 and the refold line 105 faces each panel surface 5 of the square container 2. The fold line 104 and the refold line 105 of the cylindrical label 3 face each other at substantially the center of each corner surface 6 by being inserted into the container body 22. Finally, the cylindrical label 3 is thermally shrunk so that the center seal portion 31 is disposed in a region corresponding to the one corner surface 6 as shown in FIG. 1, and the corners on both sides of the one panel surface 5 ′. The rectangular container 1 with a cylindrical label in which the perforations 7 and 7 are arranged in the region corresponding to the surface 6 can be manufactured.

Next, the modification of the said cylindrical label continuous body is shown.
In the flat cylindrical label continuous body 102 according to the modification shown in FIG. 7A, the perforation 7 is provided in the vicinity of one fold line 104, and the center seal portion 31 is formed from the fold line 104. A second perforation 7 is formed in the vicinity of the position rotated 90 degrees in the circumferential direction of the cylindrical body to the non-side. When the cylindrical label 3 obtained from the cylindrical label continuous body 102 is attached to the container 2, the perforation 7 and the center seal portion 31 are not simultaneously disposed in the corresponding region of the one corner surface 6. A square container 1 with a cylindrical label in which perforations 7 and 7 are respectively formed in the corresponding regions of the corner surfaces 6 and 6 on both sides is obtained.
In the flat cylindrical label continuous body 102 according to the modification shown in FIG. 7B, the perforation 7 is provided in the vicinity of one fold line 104, and both sides in the circumferential direction of the cylindrical body are formed from the fold line 104. The perforations 7 and 7 are formed in the vicinity of the position rotated 90 degrees respectively, that is, when the rectangular container 1 with a cylindrical label is formed, the perforations are formed in areas corresponding to the three corner surfaces 6. 7 are formed respectively.
In the flat cylindrical label continuous body 102 according to the modification shown in FIG. 7C, perforations 7 are provided in the vicinity of both the folds 104, 104, respectively. Perforations 7 and 7 are formed in the vicinity of the positions rotated 90 degrees on both sides in the circumferential direction, that is, when the rectangular container 1 with a cylindrical label is formed, the areas corresponding to the four corner surfaces 6 are formed. The perforations 7 are respectively formed.

Moreover, the modification shown in FIG. 8 shows the cylindrical label continuous body 102 from which the method of folding in flat shape differs from what is shown in FIGS.
As shown in FIG. 8, the cylindrical label continuous body 102 according to this modification has a position in which the central portion in the width direction when being flattened is rotated 45 degrees from the center seal portion 31 in the circumferential direction of the cylindrical body. It is folded to become. Accordingly, the center seal portion 31 is located at a position rotated 45 degrees in the circumferential direction from the one fold line 104, and at each position (or the vicinity thereof) rotated 45 degrees on both sides in the circumferential direction from the one fold line 104. The first perforation 7 ′ and the second perforation 7 ″ are provided.
The flat cylindrical label continuous body 102 according to the present modification is flattened again by overlapping the two fold lines 104, 104 and refolded in the same manner as described above. By such refolding, two refolds 105 are respectively formed at positions rotated from the two folds 104 by 90 degrees in the circumferential direction of the cylindrical body. And by opening this before inserting in the container 2, as shown to Fig.9 (a), as shown to Fig.9 (a), as for the cylindrical label 3, the substantially square-shaped opening part bent in each fold line 104 and the refold line 105 is shown. Arise. In this state, as shown in FIG. 2B, the cylindrical label 3 is arranged such that the center of the four sides between each fold line 104 and the refold line 105 faces each corner surface 6 of the square container 2. A center seal portion 31 is disposed in a region corresponding to one corner surface 6 as shown in FIG. 1 by being inserted into the container body portion 22 and thermally contracted, and the corner surfaces on both sides of one panel surface 5 ′. The square container 1 with the cylindrical label in which the perforations 7 and 7 are respectively arranged in the region corresponding to 6 can be manufactured.
It is also possible to form three or more perforations 7 for the cylindrical label continuous body 102 according to this modification.

For example, adjacent panels across the corner surface 6 Containers having a rectangular cross-section with different widths of the surface 5 can also be used.
Moreover, in each said embodiment, although between the panel surface 5 and the corner surface 6 (boundary part) is formed in the obtuse angle shape, this part may be formed in the loose circular arc shape. Furthermore, the corner surface 6 is not limited to a flat shape, and may be formed in a slightly swelled or recessed arc surface.

Further, in the above embodiment, the perforation line 7 is used as the easy-cleavage line because it is excellent in label dividing property and easy to form. However, the easy-cleavage line is not limited to the perforation line 7, and the label is arranged in the thickness direction. It is also possible to use a cut half-cut line or a tear tape attached to the inner surface of the cylindrical label 3 as an easy-cleavage line. Moreover, you may form the notch part which continues to an easy-cleavage line as a division | segmentation start point in the upper edge part of the cylindrical label 3 as a division | segmentation start point.
