Description

  The present invention relates to a labeled container in which a lidded container is sealed with a cylindrical label.

  Conventionally, there is a cylindrical label that covers a container with a lid formed with a vertical perforation and a horizontal perforation (Patent Documents 1 and 2 below). The upper sealing portion is divided in the vertical direction, and further, the horizontal perforation is cut to separate and remove the sealing portion while leaving the remaining label portion below the horizontal perforation on the container main body to expose the lid. .

  However, instead of cutting the vertical perforation by mischief at the store, etc., if the horizontal perforation is threaded and cut by gripping and rotating the lid, the horizontal perforation will be cut cleanly in a straight line. When the lid is returned to the original position, it cannot be easily determined whether or not the horizontal perforation is cut. That is, there is a problem that it cannot be easily determined that the package has been opened by mischief.

  Therefore, it has also been proposed to provide a tamper-proof function by devising the perforation shape of the cylindrical label (Patent Document 3 below). However, since the shape of the perforation is complicated, the manufacturing becomes complicated and the appearance of the cylindrical label is likely to deteriorate.

  In addition, as described in Patent Document 4 below, not the opening structure that cuts the vertical perforation, but also the opening structure that cuts and opens the horizontal perforation by rotating the lid in the opening direction, as described above. Such problems can occur as well.

  Therefore, the present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a labeled container that can improve the function of preventing falsification.

  The present invention has been made to solve the above-mentioned problems, and the labeled container according to the present invention seals a container with a lid whose lid is rotatably attached to the outer peripheral surface of the mouth of the container body. A cylindrical label is attached, and the cylindrical label is a container with a label in which a horizontal perforation for opening is formed along a circumferential direction for dividing the cylindrical label in a vertical direction. A tack label is attached so as to straddle the label splitting planned position, and the label base material of the tack label is made of a material that is more easily extended than the label base material of the cylindrical label. In addition, the label base material of a tack label should just extend more easily than the label base material of a cylindrical label on the basis of the mounting state to a container.

  In the labeled container of this configuration, the tack label is stuck so as to straddle the splitting position of the cylindrical label up and down, and the label base material of the tack label is more than the label base material of the cylindrical label Since it is made of an easily stretchable material, if the horizontal perforation of the cylindrical label is threaded by mischief and the tack label is threaded at the same time, the tack label is stretched by being pulled in the circumferential direction at that time. Therefore, the tack label is not cut in a straight line along the circumferential direction, and the cut portion is stretched or wrinkled, or the cut portion is jagged. Therefore, even if the lid is returned to the original position after opening due to mischief, the cut portion of the tack label can be easily visually recognized, and it can be easily determined that the opening has been performed. Therefore, it is possible to prevent mischief at a storefront or the like, and a high deterrent effect can be obtained against mischief.

  In particular, the label base material of the cylindrical label is a heat-shrinkable film containing as a main component any one of polyethylene terephthalate resin, polystyrene resin, polypropylene resin, and polylactic acid resin. Is preferably a non-heat-shrinkable film containing a polyethylene resin. If each label base material of the cylindrical label and the tack label is made of such a material, the cylindrical label is relatively difficult to stretch when opened, and the tack label is relatively easy to stretch, and there is a difference in elongation between the two. It becomes easy to occur and a high anti-tampering function is obtained. In addition, when a cylindrical label is a heat-shrinkable film, the label base material of a tack label should just extend easily with respect to the label base material of the cylindrical label after heat shrink.

  Moreover, it is preferable that the label base material of a cylindrical label is a stretched film, and the label base material of a tack label is an unstretched film. Even with this configuration, the cylindrical label is relatively difficult to stretch at the time of opening, and the tack label is relatively easy to stretch. Thus, a difference in elongation is likely to occur between the two, and a high anti-tampering function can be obtained.

  Furthermore, it is preferable that the back surface of the tack label is divided into a strong adhesion region and a weak adhesion region, and the weak adhesion region of the tack label is located at a planned division position of the cylindrical label. In the case of this configuration, the tack label is cut at the weak adhesion region by opening, but the weak adhesion region of the tack label does not follow the cylindrical label at the time of opening, so that it tends to stretch. Therefore, the cut portion of the tack label can be easily visually recognized after opening, and the function of preventing tampering is enhanced.

  As described above, since the tack label is extended at the time of opening by mischief, the cut portion can be easily visually recognized, and the function of preventing falsification is enhanced.

  Hereinafter, a labeled container according to an embodiment of the present invention will be described with reference to FIGS. The labeled container shown in FIG. 1 includes a bottomed cylindrical container body 2 that opens upward, and a lid 3 that is screwed to the outer peripheral surface of the mouth 23 to seal the opening of the container body 2. The cylindrical label 1 is attached to a container with a lid. FIG. 1 shows a state before opening. A tack label 4 is attached to a predetermined position of the cylindrical label 1.

  There are various forms of containers with lids, such as those made of synthetic resin (so-called PET bottles), those made of metal, also called bottle cans, and those made of glass. In this embodiment, the container body 2 and the lid 3 are used. Are all made of synthetic resin. The contents are also arbitrary, and are, for example, seasonings, beverages, foods, pharmaceuticals, cosmetics, and the like.

  The container is composed of a container body 2 and a lid 3. The container main body 2 has a male screw portion 24 (see FIG. 3) to which the lid 3 is screwed on the outer peripheral surface, a small-diameter mouth portion 23 having an opening at the upper end portion, and a larger diameter than the mouth portion 23. The body portion 21 occupying most of the container body 2 and the shoulder portion 22 which is located between the mouth portion 23 and the body portion 21 and gradually increases in diameter from the mouth portion 23 toward the body portion 21. And a bottom portion 20 located below the trunk portion 21. The trunk portion 21 is a portion having the maximum circumferential length in the container. The lid 3, the mouth portion 23, and the shoulder portion 22 have a shorter circumferential length than the trunk portion 21, and the shoulder portion 22 faces the trunk portion 21. This is the part where the circumference gradually increases.

  The lid 3 has a structure of an upper end closed lower end opening composed of a circular top surface portion 31 and a cylindrical peripheral wall portion 32 that hangs vertically downward from the periphery of the top surface portion 31, and is formed on the inner peripheral surface of the peripheral wall portion 32. A female screw portion (not shown) that can be screwed with the male screw portion 24 formed on the outer peripheral surface of the mouth portion 23 of the container body 2 is formed. In this embodiment, the lid 3 is a normal right-hand screw type, and loosens when rotated counterclockwise in a plan view and tightens when rotated counterclockwise. That is, the opening direction of the lid 3 is counterclockwise in plan view, is rightward in front view, and the upstream side in the opening direction is left side in front view. Therefore, in the drawing viewed from the front, the left side is the upstream side in the opening direction, and the right side is the downstream side in the opening direction. 4A, the opening direction is indicated by an arrow A, and the closing direction is indicated by an arrow B in FIG. In addition, it is not limited to the structure by which the lid | cover 3 was screwed by the outer peripheral surface of the mouth part 23 of the container main body 2, The lid | cover 3 should just be rotatably attached to the outer peripheral surface of the mouth part 23 of the container main body 2. . For example, the lid 3 is attached to the lid body portion rotatably attached to the outer peripheral surface of the mouth portion 23 of the container body 2, and an opening / closing portion that is hinged and can be opened and closed separately is used for taking out the contents. The structure provided may be sufficient. In the case of this configuration, the lid main body portion idles at the mounting position without changing the position in the vertical direction (axial direction) with respect to the mouth portion 23 of the container main body 2. And when taking out the contents, the opening / closing part is opened upward and taken out. Furthermore, as a container, the form which has the opening part 23 in the lower part of the container main body 2, and the lid | cover 3 screwed in the opening part 23 like a tubular container etc. may be sufficient, for example.

  The cylindrical label 1 is a heat-shrinkable label (shrink label) and covers substantially the entire container with a lid, and has a so-called full shrink structure. When the cylindrical label 1 is attached to the container, the container lid 3 is sealed so as not to open. The cylindrical label 1 covers the entire peripheral wall portion 32 of the lid 3, and its upper end portion 1 a wraps around the top surface portion 31 of the lid 3 to cover the peripheral portion of the top surface portion 31, so that the mouth of the container body 2 23, the shoulder portion 22, and the entire body portion 21 are covered, and the lower end portion 1 b of the lower end portion 1 b extends around the bottom portion 20 to cover the peripheral edge portion of the bottom portion 20.

  A horizontal perforation 10 for opening is formed at a predetermined position of the cylindrical label 1. The horizontal perforation 10 is formed along the circumferential direction so as to divide the cylindrical label 1 in the vertical direction. The horizontal perforation 10 allows the cylindrical label 1 to be separated from the upper sealing portion 11 and the lower residual label portion. It is divided into 12. That is, the cylindrical label 1 is divided into an upper part and a lower part by the horizontal perforation 10, and is divided into an upper part and a lower part by opening. Therefore, the part where the horizontal perforation 10 is formed is the scheduled cutting position. And the upper part of the cylindrical label 1 is the sealing part 11 for sealing the lid | cover 3, and the lower part is the residual label part 12 which remains in the container main body 2 after opening and becomes a main body label. The position of the horizontal perforation 10 is arbitrary, but it is located below the lower end 3a of the lid 3 in order to ensure at least sealing performance. Specifically, the horizontal perforation 10 is located on the shoulder 22 of the container body 2, and the portion of the cylindrical label 1 covering the shoulder 22 is partitioned vertically by the horizontal perforation 10 and divided vertically by opening. Is done. The specific shape of the horizontal perforation 10 is arbitrary, and it is sufficient that the cut portion and the non-cut portion that is the remaining portion that is not formed are alternately formed. The length and interval of the parts may vary. Moreover, although the horizontal perforation 10 may be formed over the entire circumference, a region not formed in a part of the entire circumference may be provided.

  And the vertical perforation 13 for opening is formed in the sealing part 11 of the cylindrical label 1. FIG. The form of the vertical perforations 13 may be various and may be a single form, but in this embodiment, the form is two parallel to each other, and the horizontal perforation from the upper end 1a of the cylindrical label 1 10 is formed. By forming the two vertical perforations 13, a strip-shaped piece 14 is formed between them. At the time of opening, by picking the knob 15 (see FIG. 2), cutting the vertical perforation 13 and cutting the separation piece 14 from the other part of the sealing part 11, and then cutting the horizontal perforation 10, The remaining part of the sealing part 11 can be separated and removed to completely expose the lid 3. In this embodiment, the vertical perforation 13 is formed in addition to the horizontal perforation 10, but only the horizontal perforation 10 is formed without forming the vertical perforation 13, and the lid 3 is gripped when opened. The horizontal perforation 10 may be threaded and cut.

  In addition, in the state before mounting | wearing with a container, the cylindrical label 1 is folded flat like FIG. 2, and a crease is formed in the right-and-left both-sides edge part. As will be described later, when the horizontal perforation 10 is formed by the pressing blade in the folded state, the horizontal perforation 10 formed on the front half side of the cylindrical label 1 and the horizontal perforation formed on the back half side. The perforation 10 is formed at a time by the pressing blade. Therefore, in the expanded state, the horizontal perforation 10 formed in the front half-periphery and the horizontal perforation 10 formed in the rear half-periphery are in a longitudinally symmetrical relationship. Further, by forming one vertical perforation 13 on the front half-periphery, one vertical perforation 13 is also formed on the rear half-periphery at the same time. A crease will be located. When the horizontal perforation 10 is formed on the cylindrical label 1 with a pressing blade or the like before the tack label 4 is adhered to the cylindrical label 1, the horizontal perforation 10 can be formed over the entire circumference, The tack label 4 can be stuck on the horizontal perforation 10. On the other hand, in the case where the horizontal perforation 10 of the cylindrical label 1 is formed by the pressing blade after the tack label 4 is attached to the cylindrical label 1, the cut line such as the perforation is not formed on the tack label 4. In the case of making the cylindrical label 1, the part where the tack label 4 is pasted and the part where the tack label 4 is pasted are opposed to each other as a boundary line in the entire circumference of the scheduled division position of the cylindrical label 1 The horizontal perforation 10 is formed except for a total of two places. Therefore, in that case, of the entire circumference of the position where the cylindrical label 1 is scheduled to be divided, the portion where the tack label 4 is attached and the portion where the tack label 4 is attached are opposed to each other as a crease boundary line. There are portions where the horizontal perforations 10 are not formed in two places in total. Thus, the horizontal perforation 10 may be formed over the entire circumference, or there may be a portion that is not partially formed in the entire circumference.

  Here, the cylindrical label 1 is provided with the label base material and the printing layer formed in the outer surface (front surface) or inner surface (back surface) of this label base material. Various heat-shrinkable films (shrink films) can be used as the label substrate, and uniaxially stretched films that shrink mainly in one direction (circumferential direction when formed into a cylindrical shape) can be used. You may use the biaxially stretched film which shrink | contracts also in the direction orthogonally crossed. In addition, a uniaxially stretched film means a film that is substantially uniaxially stretched, and means a film that has greatly different shrinkage rates in one direction (for example, TD direction) and the other direction (for example, MD direction). It does not mean only a film that does not shrink at all (so-called shrinkage rate is zero). Specifically, for example, a film having a thermal contraction rate of 20 to 80% in the circumferential direction and a thermal contraction rate of −5 to 10% in the axial direction at 90 ° C. for 10 seconds (warm water treatment) can be mentioned. For example, in the case of a uniaxially stretched film that contracts mainly in the circumferential direction, the circumferential direction is the main stretching direction.

  Specific examples of the plastic film used as the label substrate include polyolefins such as polypropylene (PP), polyesters such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), polystyrenes (PS), and polylactic acid (PLA). ), A film made of a polyamide-based resin and a vinyl-based resin such as polyvinyl chloride. Among these, a polyethylene terephthalate film, a polypropylene film, a polystyrene film, and a polylactic acid film are particularly preferable because they have appropriate shrinkage stress. A uniaxially stretched film that contracts mainly in the circumferential direction is preferred. Although the thickness of a label base material is not specifically limited, It is preferable that it is 8-100 micrometers, More preferably, it is 10-80 micrometers, Most preferably, it is 15-60 micrometers.

  Moreover, the film containing the resin mixture which mixed 2 or more types of the above-mentioned resin can also be used. Furthermore, in addition to a single layer film, a laminated film in which two or more kinds of films are laminated can also be used. In the case of a laminated film, it is preferable to include any of a polyethylene terephthalate resin, a polystyrene resin, a polypropylene resin, and a polylactic acid resin and that these resins become the main layer of the label substrate. Thus, the label base material is preferably a heat-shrinkable film containing any one of polyethylene terephthalate resin, polystyrene resin, polypropylene resin, and polylactic acid resin as a main component.

  The horizontal perforation 10 is located at the boundary between the upper sealing portion 11 and the lower residual label portion 12. At the time of opening, the cylindrical label 1 is divided up and down by the horizontal perforation 10. Therefore, the horizontal perforation 10 is for dividing the cylindrical label 1 vertically. A tack label 4 is attached to the scheduled division position. The tack label 4 is attached to one part of the entire circumference of the scheduled cutting position where the horizontal perforation 10 is formed, and is attached so as to straddle the scheduled cutting position vertically. In this embodiment, the tack label 4 is pasted so that the planned split position is located at the center in the vertical direction. For example, the tack label 4 is offset to the upper or lower side with respect to the planned split position. May be worn. Moreover, you may make it stick in two or more places other than sticking the tack label 4 in one place among the perimeters. The shape of the tack label 4 is also arbitrary and may be various shapes, but in the present embodiment, it is a vertically long rectangular shape. The center position in the vertical direction of the tack label 4 substantially coincides with the scheduled division position of the cylindrical label 1.

  Here, the tack label 4 has a label base material and an adhesive layer laminated on the back surface of the label base material. The label base material of the tack label 4 is made of a material that is easily stretched when pulled than the label base material of the cylindrical label 1. The label base material of the tack label 4 is not particularly limited as long as it is a flexible sheet and can be easily cut at the time of opening, and various known materials can be used. Is a plastic film and may have a single-layer structure or a multilayer structure of two or more layers. The label base material of the tack label 4 is preferably non-heat-shrinkable. Since the label base material of the tack label 4 is made of a material that is easier to stretch than the label base material of the cylindrical label 1, an unstretched film is preferable in the case of a plastic film. Here, the non-stretched film is a film in which the molecular orientation is non-oriented (not subjected to the alignment treatment). It is preferable that the label base material of the cylindrical label 1 is composed of a stretched film, and the label base material of the tack label 4 is composed of an unstretched film, so that a difference is provided between the two when stretched. Typical examples of plastic films include olefinic films such as polypropylene films and polyethylene films, but among them, polyethylene films are particularly flexible and have the ability to stick to 2D and 3D curved surfaces. It is preferable because it is excellent. In addition to a single-layer film, a laminated film in which two or more kinds of films are laminated can be used. In the case of a laminated film, it is particularly preferable that a polyethylene resin is the main layer of the label substrate. Thus, the label base material of the tack label 4 is preferably a non-heat-shrinkable film containing a polyethylene-based resin, and particularly preferably a non-heat-shrinkable film containing a polyethylene-based resin as a main component. Although the thickness of the label base material of the tack label 4 is not specifically limited, For example, they are 25 micrometers-120 micrometers, Preferably they are 30 micrometers-100 micrometers.

  The material of the label base material of the tack label 4 is preferably a material that can be stretched even with a weak force, and the tensile stress when giving 20% elongation is preferably 1 to 20 MPa, more preferably 3 to 3. 15 MPa. Further, it is a material that is difficult to return to the original state once stretched, and after giving a strain of 200%, the permanent strain is preferably 100% or more. Here, the tensile stress can be determined according to JIS K7127. Specifically, the material used for the label base material is cut into a width of 15 mm and a length of 200 mm to produce a test piece. The test piece is fixed to the apparatus with a distance between the marked lines of 100 mm, and the value obtained when the distance between the marked lines becomes 120 mm (strain is 20%) at the tensile speed of 300 mm / min is obtained as the tensile stress. Can do. Here, measurement can be performed using an apparatus (AG-I 500N) manufactured by Shimadzu Corporation. In the same manner as described above, it is possible to check whether the material is stretched by 200% by pulling up to a distance between marked lines of 300 mm (distortion is 200%). Furthermore, about what was able to be pulled, after pulling, the distance between the marked lines of the unloaded test piece can be measured, and permanent distortion can be measured. In this case, it is preferable that the elongation is 200% or more, and that the permanent set is 100% or more.

  The label base material of the tack label 4 may be transparent or opaque. Since a plastic film is usually transparent, an opaque label substrate can be obtained by applying white solid printing or silver solid printing to a transparent plastic film. Moreover, it is good also as an opaque label base material by laminating | stacking an opaque layer like a metal vapor deposition film on a plastic film.

  A desired printed layer may be formed on the front surface or the back surface of the label base material of the tack label 4 as necessary. When an opaque label substrate is used, a printing layer is provided on the surface. When the printing layer is provided on the tack label 4 in this way, it is preferable that the color is different from the color of the printing layer of the cylindrical label 1 located inside thereof, and it is opened by mischief and returned to the original position. Even so, since the printed layer of the inner cylindrical label 1 can be seen from the cut portion 4a of the tack label 4, it can be easily visually confirmed that it has been opened. Similarly, if printing layers of different colors (for example, printing layers having complementary colors) are formed on the front surface and the back surface of the tack label 4, the printing layer on the inner surface of the tack label 4 from the cut portion 4 a of the tack label 4. Since it is possible to see a glimpse, it can be easily seen that it has been opened.

  As the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer, various known ones can be used. For example, a pressure-sensitive pressure-sensitive adhesive composed of an acrylic resin, a urethane resin, a styrene resin, or the like can be used. A heat-sensitive adhesive may also be used. The thickness of the pressure-sensitive adhesive layer is, for example, 10 to 30 μm. The pressure-sensitive adhesive layer is formed on the entire back surface of the label substrate, but may be formed on only a part.

  Although the container with a label of the above structure can be manufactured by attaching the tack label 4 to the predetermined position of the cylindrical label 1 after mounting | wearing the cylindrical label 1 to a container, for example, it is preferable. Is manufactured by attaching the tack label 4 to the cylindrical label 1 at the stage before being attached to the container, and then attaching the cylindrical label 1 with the tack label 4 to the container. As described above, when the tack label 4 is attached to the cylindrical label 1 before being attached to the container, the tack label 4 can be accurately and surely attached to the scheduled division position of the cylindrical label 1. In particular, in the configuration in which the tack label 4 is positioned on the shoulder portion 22 of the container, the shoulder portion 22 is inclined, and thus the tack label 4 is attached by a labeler (label sticking device) after the cylindrical label 1 is attached to the container. It is not easy to mechanically attach. Therefore, in the configuration in which at least a part of the tack label 4 is located on the shoulder portion 22 of the container, it is preferable to stick the tack label 4 to the cylindrical label 1 at a stage before being mounted on the container.

  In addition, a long film obtained by cutting a raw film into a predetermined width is formed into a cylindrical shape to form a long cylindrical long label, and the long label is cut into predetermined lengths to form individual cylinders. In the case of forming the label 1, the horizontal perforations 10 are sequentially formed at regular intervals on the long label in which the cylindrical label 1 is continuously provided in the longitudinal direction, and the tack labels 4 are sequentially pasted. It is preferable to wear it.

  When opening the container with the label configured as described above, first, the knob 15 is picked to cut the vertical perforation 13 while cutting the separation piece 14 from the other part of the sealing part 11, and then the horizontal The perforation 10 is cut, and the remaining portion of the sealing portion 11 is separated and removed to completely expose the lid 3. In this way, the sealing portion 11 is separated and removed from the container by opening, while the remaining label portion 12 remains on the container main body 2 as it is to become a main body label. Further, by cutting the horizontal perforation 10, the tack label 4 is also divided into upper and lower parts, the upper part of the tack label 4 is separated and removed together with the sealing part 11, and the lower part of the tack label 4 remains attached to the remaining label part 12. Remains.

  On the other hand, as shown in FIG. 3, considering a case where the vertical perforation 13 is not cut and the lid 3 is grasped and rotated so that only the horizontal perforation 10 is cut by screwing, as shown in FIG. Since the label base material of the tack label 4 that is stuck so as to straddle the splitting position vertically is made of a material that is easier to extend than the label base material of the cylindrical label 1, the tack label 4 is threaded together with the cylindrical label 1. At this time, the tack label 4 is stretched by being pulled in the circumferential direction. Therefore, the tack label 4 is not cut in a straight line along the circumferential direction, and the cut portion 4a is elongated or wrinkled, or the cut portion 4a has a jagged shape. The same applies when the lid 3 is rotated by a small angle as shown in FIG. 4A, and burrs, wrinkles, elongation, etc. occur at the cut portion 4a, or the cut portion 4a becomes jagged. .

  Therefore, even if the lid 3 is returned to the original position as shown in FIG. 4B, the cut portion 4a of the tack label 4 is not straight, so that the cut portion 4a can be easily seen and opened by mischief. This can be easily determined. Therefore, it is possible to prevent opening at the store etc. due to mischief, and a high deterrent effect against mischief can be obtained.

  Moreover, when the horizontal perforation 10 is formed at a position corresponding to the shoulder portion 22 of the container as in the present embodiment, it is particularly effective to attach the tack label 4. That is, the shrinkage amount of the cylindrical label 1 is larger than that of the trunk portion 21 at the position of the shoulder portion 22, and therefore the portion of the cylindrical label 1 in the shoulder portion 22 is larger than the portion of the cylindrical label 1 in the trunk portion 21. It is relatively hard. Therefore, the horizontal perforation 10 is easily cut in a straight line when opening due to mischief, and it is not easy to determine that the horizontal perforation 10 is opened alone. Therefore, when the horizontal perforation 10 is provided at a position corresponding to the shoulder 22, the tampering prevention effect by attaching the tack label 4 is particularly great.

  Further, the tack label 4 is attached to the cylindrical label 1 by the pressure-sensitive adhesive layer, and the pressure-sensitive adhesive layer is interposed between the label base material of the tack label 4 and the cylindrical label 1. Therefore, the tuck label 4 may be slightly displaced in the circumferential direction from the cylindrical label 1 when opened by mischief. When the tack label 4 is cut while being slightly displaced in the circumferential direction from the cylindrical label 1 in this way, the upper portion of the tack label 4 remains at the upper position even if the tack label 4 is returned to the original position as shown in FIG. It does not return to the original position completely with respect to the lower part of the sheet, but is slightly displaced in the circumferential direction, so that it can be easily determined that it has been opened. Similarly, the tuck label 4 may be wrinkled at the time of opening, and even if such wrinkle is generated, it is opened by the generated wrinkle even if it is returned to the original position as shown in FIG. Can be determined.

  In the present embodiment, the entire area of the tack label 4 is not provided with a defective portion such as a cut line or a notch, that is, the entire area is defined as a non-defective area. In this case, a cutting start portion serving as a starting point for cutting the tack label 4 may be formed at a position corresponding to the scheduled cutting position of the cylindrical label 1. For example, the cut lines 40 may be formed on both side edges as shown in FIG. The cut line 40 may be formed at least on the side edge on the upstream side in the opening direction among the side edges. The cut line 40 of the tack label 4 and the horizontal perforation 10 of the cylindrical label 1 are preferably formed at the same position in the vertical direction, that is, in the axial direction of the cylindrical label 1 as shown in FIG. The position may be shifted. Further, when the tack labels 4 are formed on both side edges, it is preferable to form them symmetrically, but they may be asymmetrical.

  If the cut line 40 as the cutting start portion is formed in the tack label 4 in this way, the tack label 4 can be easily formed from the cut line 40 when the horizontal perforation 10 of the cylindrical label 1 is threaded when opened. It can cut | disconnect and an openability improves. Further, even if the cut lines 40 are formed on both side edges of the tack label 4 in this way, the intermediate area 41 of the tack label 4 is a non-defect area, so when the tack label 4 is threaded when opened by mischief, The intermediate region 41 of the tack label 4 extends and wrinkles, stretches, burrs, etc. occur at the cut portion 4a, or the cut portion 4a becomes jagged. Therefore, the cut portion 4a of the tack label 4 can be easily visually recognized, and it can be easily determined that it has been opened.

  In addition, when forming the cut line 40 in the side edge part of the tack label 4, the vertical alignment of the cut line 40 of the tack label 4 and the horizontal perforation 10 of the cylindrical label 1 (the axial direction of the cylindrical label 1). Is a problem. As described above, the cut line 40 of the tack label 4 and the horizontal perforation 10 of the cylindrical label 1 may be slightly displaced in the vertical direction, but it is preferable that they coincide with each other. The horizontal perforation 10 may be formed on the cylindrical label 1 before being attached to the container, and then the tack label 4 having the cut line 40 may be attached to the cylindrical label 1. It is difficult to accurately position the four cut lines 40 and the horizontal perforation 10 of the cylindrical label 1. Therefore, before the horizontal perforation 10 is formed on the cylindrical label 1, the tack label 4 in a state in which the cut line 40 is not formed is attached to the cylindrical label 1. Preferably, the perforation line 10 and the cut line 40 of the tack label 4 are formed. In that case, if the tack label 4 is stuck to the cylindrical label 1 folded in a flat state as shown in FIG. 2, the sticking process becomes easy. Moreover, if the horizontal perforation 10 is formed in the cylindrical label 1 folded in the flat state, the horizontal perforation 10 can be easily formed by the pressing blade.

  Furthermore, although the formation process of the horizontal perforation 10 of the cylindrical label 1 and the formation process of the cut line 40 of the tack label 4 may be performed separately, it is preferable to form them simultaneously in one process. For example, when the horizontal perforation 10 of the cylindrical label 1 and the cut line 40 of the tack label 4 are formed in one step by pressing with a pressing blade, the horizontal perforation 10 of the cylindrical label 1 and the cut line 40 of the tack label 4 are formed. It can be formed at the same position with high accuracy. In the case where the horizontal perforation 10 and the cut line 40 of the tack label 4 are simultaneously formed by the pressing blade in a state in which the cylindrical label 1 is folded flat, the cylindrical label 1 positioned on the back side of the tack label 4 The horizontal perforation 10 is not locally formed in the portion, and the portion of the cylindrical label 1 that is opposite to the portion of the cylindrical label 1 located on the back side of the tack label 4 and that is opposed to the front and rear. Similarly, the horizontal perforation 10 is not locally formed. Therefore, a total of two places, the part where the tack label 4 is attached and the part where the tack label 4 is attached to the attaching part of the tack label 4 as the boundary line in the entire circumference of the scheduled division position of the cylindrical label 1 There is a portion where the horizontal perforation 10 is not formed.

  When the horizontal perforation 10 of the cylindrical label 1 and the cut line 40 of the tack label 4 are simultaneously formed in one process, the cut line 40 of the tack label 4 and the cut portion of the horizontal perforation 10 of the cylindrical label 1 Can be accurately formed at the same position in the axial direction of the cylindrical label 1, so that the tack label 4 can be more easily cut together with the cylindrical label 1 from the cut line 40 when opening.

  Further, when the horizontal perforation 10 of the cylindrical label 1 and the cut line 40 of the tack label 4 are simultaneously formed in one process, the intermediate area 41 of the tack label 4 is made a non-defect area, Since the scheduled cutting position of the cylindrical label 1 located inside is a portion where the cut portion of the horizontal perforation 10 is not formed (becomes a non-cut portion of the horizontal perforation 10), the intermediate region 41 of the tack label 4 and its It becomes difficult to cut the planned division position of the inner cylindrical label 1 in a straight line along the circumferential direction, and it is possible to more easily discriminate opening due to mischief.

  Instead of the cut line 40, the notch portion 42 may be formed as a cutting start portion as shown in FIG. The shape of the notch 42 is arbitrary, and may be V-shaped (triangular) as shown in FIG. 6A, for example, or may be semicircular as shown in FIG. 6B. . In addition, various shapes such as a U-shape and a rectangle may be used. Further, when the cutout portion 42 is formed, the horizontal perforation 10 of the cylindrical label 1 is tucked so that the cut portion of the horizontal perforation 10 of the cylindrical label 1 is located in the region cut out by the cutout portion 42. It is preferably formed in the vicinity of the notch 42 of the label 4. Further, as shown in FIG. 6B, a cut line 40 may be formed together with the cutout portion 42 as a cutting start portion.

  5 and 6, the intermediate region 41 at the position of the tack label 4 corresponding to the scheduled division position of the cylindrical label 1 and inside the both side edges is removed from the cut line 40 or the like. Although a non-defect region without a portion is used, the intermediate region 41 may not be a non-defect region, and a crossed cut line 43 different from the horizontal perforation 10 may be formed in the intermediate region 41. The intersecting cut line 43 extends along a direction intersecting with the horizontal perforation 10. For example, as shown in FIG. 7A, the intersecting cut line 43 extends along a direction orthogonal to the horizontal perforation 10. It is good also as a shape extended. As shown in FIG. 7A, a plurality of intersecting cut lines 43 may be formed at intervals, or only one may be formed. Moreover, it is good also as the cross-shaped cut line 43 which cross | intersects diagonally with respect to the horizontal perforation 10 like FIG.7 (b). Further, as shown in FIG. 7C, two intersecting cut lines 43 that obliquely intersect the horizontal perforation line 10 are formed, and the two intersecting cut lines 43 intersect each other. May be. That is, the crossed cut lines 43 may be formed in an X shape.

  Of course, a plurality of intersecting cut lines 43 as shown in FIGS. 7B and 7C may be formed at intervals in the width direction of the tack label 4. In any case, when the cut line is formed in the intermediate region 41, it is not in a shape extending in the lateral direction (width direction), that is, in the circumferential direction of the cylindrical label 1, but in the circumferential direction of the cylindrical label 1. It is preferable to have a shape extending in the intersecting direction. If a cut line such as a perforation that is collinear with the horizontal perforation 10 is formed in the intermediate region 41 of the tack label 4, the tuck label 4 is easily cut along with the cylindrical label 1 when opened by mischief. . Therefore, when the cut line is formed in the intermediate region 41 of the tack label 4, it is preferable to have a shape extending so as to cross the perforation unlike the horizontal perforation 10. In addition, when forming the crossing cut line 43 in the intermediate area 41 in this way, the crossing cut line 43 is also pressed together with the cut line 40 as the cutting start portion and the horizontal perforation 10 of the cylindrical label 1. It is preferable to form with a blade at once. When the crossed cut line 43 is formed in the intermediate region 41 with the pressing blade, the crossed cut line is also formed on the cylindrical label 1 at the same time.

  Furthermore, the hole 47 may be formed in the intermediate region 41 instead of the intersecting cut line 43. The shape of the hole 47 is arbitrary, and may be, for example, a circle as shown in FIG. 8A or an ellipse as shown in FIG. The hole 47 may be formed at one position in the center of the intermediate area 41, or may be formed at one position that is eccentric to the left or right from the center of the intermediate area 41, or at intervals in the width direction. And may be formed at a plurality of locations. When the hole 47 as shown in FIG. 8B is elliptical, the direction of the major axis may be the width direction of the tack label 4 (circumferential direction of the cylindrical label 1), or a cross-shaped cut. It may intersect with the width direction of the tack label 4 like a line 43. Thus, even when the hole 47 is formed in the intermediate region 41, the tuck label 4 becomes difficult to be cut in a straight line when opening due to mischief, and a step or a burr or the like is generated at the cut portion 4a in the hole 47. To do. Therefore, it can be easily recognized that it has been opened by mischief.

  Furthermore, a weak adhesion region 44 may be formed on a part of the back surface of the tack label 4. That is, the strong adhesion region 45 and the weak adhesion region 44 may be formed on the back surface of the tack label 4. The weakly bonded region 44 includes a non-bonded state having virtually no adhesive force. For example, as described above, the pressure-sensitive adhesive layer is formed on the entire back surface of the label base material, and a masking layer called “glue killing” or “glue suppression” is formed on a part of the back surface of the pressure-sensitive adhesive layer. Thus, the strong adhesion region 45 and the weak adhesion region 44 can be formed on the back surface of the tack label 4. The area where the masking layer is formed has a lower adhesive force than the area where the masking layer is not formed. Therefore, the area where the masking layer is formed on the back surface of the pressure-sensitive adhesive layer is the weakly bonded area 44, and the area remaining on the back surface of the pressure-sensitive adhesive layer where the masking layer is not formed becomes the strongly bonded area 45. The masking layer can be formed by a known printing method using a masking agent. As the masking agent, those which are non-adhesive and capable of forming on the pressure-sensitive adhesive layer a layer which is cured by ultraviolet rays are preferable, and ultraviolet curable ink or the like can be used. However, instead of forming the pressure-sensitive adhesive layer on the entire back surface of the label base material, the pressure-sensitive adhesive layer is formed only in the strong adhesion region 45 and the pressure-sensitive adhesive layer is not formed in the weak adhesion region 44, thereby strongly adhering. The region 45 and the weakly bonded region 44 may be partitioned.

  FIG. 9 shows an example in which the strong adhesion region 45 and the weak adhesion region 44 are partitioned. FIG. 9 is a rear view, and a hatched portion is a strong adhesion region 45 and a non-hatched portion is a weak adhesion region 44. For example, as shown in FIG. 9A, a strong adhesion region 45 is formed on each of the upper and lower portions of the tack label 4, and a weak adhesion region 44 is formed between the two strong adhesion regions 45. A weak adhesion region 44 is formed between the two strong adhesion regions 45 by forming the strong adhesion region 45 in two places at intervals in the vertical direction, but in the case of vertical symmetry, the weak adhesion region 44 is formed at the center. Then, strong adhesion regions 45 are formed on both upper and lower sides. The weakly bonded region 44 is preferably formed along the width direction, for example, can be formed in a band shape, and in any case, it is preferably formed over the entire width of the tack label 4. The tack label 4 is attached to the cylindrical label 1 such that the weakly bonded region 44 is positioned at the planned cutting position of the cylindrical label 1. The tuck label 4 is cut at the weak adhesive region 44 by opening by mischief. However, since the weak adhesive region 44 of the tack label 4 does not follow the cylindrical label 1 at the time of opening, it can move freely and easily stretch. As a result, the cut portion 4a of the tack label 4 can be easily visually recognized after opening. In FIG. 9A, the crossed cut lines 43 are provided in the weak adhesion region 44, but this may be omitted.

  Further, as shown in FIG. 9B, the upper strong adhesive region 45 is formed by adjoining the upper side of the weak adhesive region 44 in a band shape along the width direction and a central portion at the upper end of the tack label 4. Alternatively, the weakly bonded regions 44 may be formed on both sides of the vertical portion 45b as an inverted T-shape including a vertical portion 45b formed in a band shape from the horizontal portion 45a to the horizontal portion 45a. When the weak adhesion regions 44 are formed on the left and right sides of the upper portion of the tack label 4 as described above, the weak adhesion regions 44 are lifted from the cylindrical label 1. That is, since the container is curved in the circumferential direction, the tack label 4 is also curved in the width direction accordingly. However, since the weak adhesive regions 44 are provided on the left and right in the upper part of the tack label 4, The weakly bonded region 44 is not curved, and therefore, the left and right weakly bonded regions 44 are in a state of floating without following the curved shape of the container. In particular, since at least the upper portion of the tack label 4 is located on the shoulder portion 22 of the container main body 2, the left and right weakly bonded regions 44 in the upper portion are likely to be lifted from the shoulder portion 22 of the container, It becomes conspicuous and a high advertising effect (POP effect) is obtained.

  It is also effective to use the tack label 4 as a POP label in this way, and as shown in FIG. If the upper part of the label 4 is formed wide, the pair of left and right projecting portions 46 spreads left and right as if they are open and floats from the shoulder portion 22 of the container, so that the POP effect is further enhanced. Note that the upper strong adhesion region 45 may be formed so as to gradually narrow toward the upper side as shown in FIG. 9C, instead of having an inverted T shape as shown in FIG. 9B. Well, it can be trapezoidal or triangular.

  Furthermore, a large number of intersecting cut lines 43 may be formed in the entire area of the tack label 4. For example, as shown in FIG. 10, crossed cut lines 43 extending along the vertical direction (along the direction perpendicular to the horizontal perforation 10 of the cylindrical label 1) are arranged in a staggered manner in the entire area of the tack label 4. May be. When a large number of crossed cut lines 43 are formed in this way, the tack label 4 becomes easier to extend when opened by mischief, and the function of preventing tampering is enhanced. In this case as well, the intersecting cut line 43 may have a shape extending in the oblique direction as well as a shape extending along the vertical direction, or a combination of a plurality of types of shapes. Further, the arrangement thereof is arbitrary, and in addition to the staggered arrangement, the arrangement may be a vertical and horizontal arrangement arrangement, or may be arranged randomly. Further, by forming a large number of crossed cut lines 43 on the tack label 4 in this way, the followability of the tack label 4 to the cylindrical label 1 when the cylindrical label 1 is heat-shrink mounted on the container is improved.

  The cylindrical label 1 may be a non-shrinkable label (winding label) or the like in addition to the heat-shrinkable label as described above.

  In addition, the configuration of the lid 3 can be variously changed. For example, even in the case of the right-screw type lid 3, the lid 3 is rotated by a predetermined angle clockwise in plan view, which is a direction in which the screw is temporarily tightened at the initial stage of the opening operation, By this rotation, the sealed state by the lid 3 is released, and thereafter, the lid 3 may be rotated counterclockwise in a plan view, which is the direction in which the screw is loosened, so as to be separated from the container body 2. . In such a configuration, the symbol B in FIG. 4B is the opening direction, and the upstream side in the opening direction is the right side when viewed from the front. Therefore, in that case, cutting start portions such as the cut line 40 and the cutout portion 42 are formed at least on the right side edge portion of the both side edge portions of the tack label 4.
