Description

The present invention relates to a PET bottle (plastic bottle) or cylindrical shrink label is a labeled container mounted to be installed in various containers such as glass bottles, etc..

  A container with a label to which a cylindrical shrink label is attached has a form in which the cylindrical shrink label is attached so that its lower end is positioned at a position above the bottom surface of the container. This form is sometimes referred to as an intermediate stop form because the cylindrical shrink label is attached to the middle part of the body of the container. In this case, the length of the cylindrical shrink label in the axial direction is shorter than the length of the body portion of the container. Therefore, the cylindrical shrink label is attached only to the middle portion of the outer peripheral surface of the body portion of the container.

  Thus, when mounting a cylindrical shrink label in the middle part above the bottom part of a container, it mounts as follows, for example. That is, a long label long body that is folded into a flat shape and wound into a roll is set on a labeler, and is cut into a predetermined length while feeding out the long label from the roll. A cylindrical shrink label is formed, and the cylindrical shrink label is sucked and expanded by a labeler opener, and the container is covered from above while maintaining the expanded state. At that time, a sliding layer such as a medium ink layer is formed on the inner surface of the cylindrical shrink label so that the expanded cylindrical shrink label can be smoothly put on the container (see Patent Document 1 below). The frictional resistance between the outer peripheral surface of the container is suppressed by the sliding layer, and the cylindrical shrink label can be smoothly reached to a predetermined position of the container. When the opener holding the cylindrical shrink label is lowered to a predetermined height, the opener releases the cylindrical shrink label at that position. When the cylindrical shrink label released from the opener is folded into a flat shape, the portion between the crease and the crease formed in close contact with the container stays in that position. Then, the container covered with the unshrinked cylindrical shrink label is transported to a shrink tunnel or the like as it is, where the cylindrical shrink label is heated and thermally contracted to adhere to the container.

  On the other hand, in recent years, containers having a large diameter portion on a part of the outer peripheral surface have also appeared from the viewpoint of design and the like. When a cylindrical shrink label is put on an area including such a large diameter portion, the contact area between the outer peripheral surface of the container and the cylindrical shrink label is small, so the cylindrical shrink label released from the opener is at that position. The cylindrical shrink label is liable to be displaced due to vibration during conveyance, contact with the conveyance guide, or the like. In particular, when the cylindrical shrink label is thin, the rigidity is small and the stiffness is weak, so that it is more difficult to stay in a predetermined position.

  In order to prevent such displacement of the cylindrical shrink label, it is also effective to positively spray mist-like water onto the cylindrical shrink label or the container. In many cases, water droplets are already attached to the outer peripheral surface of the container in the washing process, which is the previous process. However, by aggressively spraying water on the entire container or on a specific position of the container, an unshrinked cylindrical shape The shrink label is more difficult to be displaced.

  However, when the container has a deformed shape having a large diameter portion as described above, or when the cylindrical shrink label becomes thin and the holding power to the container becomes small, the method of positively spraying water is cylindrical. There is a limit to suppressing the displacement of the shrink label, and further improvement has been demanded.

JP 2004-354743 A

Therefore the present invention has been made in view of the above problems, and aims to provide a Lula bell with container can be reliably mounted at a predetermined position of the container.

The present invention has been made to solve the above-mentioned problems, and the labeled container according to the present invention includes a body portion formed with a large-diameter portion having a relatively large diameter with respect to the upper and lower regions. In a labeled container in which a cylindrical shrink label is attached only to a midway portion in the vertical direction including a large-diameter portion of the outer peripheral surface of the container, the cylindrical shrink label has a base film having a thickness of 10 to 30 μm, A slipping layer is formed by printing on the inner surface of the thin shrink label, and a hydrophilicity imparting agent is mixed in at least a portion in contact with the large-diameter portion of the container or a portion near the top and bottom of the slipping layer. The wetting index of the inner surface of the shrink label on which the sliding layer mixed with the imparting agent is formed is 40 or less, and the dynamic friction coefficient in the wet state of the inner surface is 1.0 or less .

In the cylindrical shrink label used for the labeled container of this configuration, since a sliding layer is formed on the inner surface, even a thin base film having a thickness of 10 to 30 μm can be smoothly covered on the container. Can do. A hydrophilicity imparting agent is mixed in at least a portion of the sliding layer that comes into contact with the large diameter portion of the container or a portion in the vicinity of the upper and lower sides , and a sliding layer in which the hydrophilicity imparting agent is mixed is formed. Since the wetting index of the inner surface of the shrink label is 40 or less and the coefficient of dynamic friction in the wet state of the inner surface is 1.0 or less, when the container is put on the container, The surface tension of the water droplet increases, and the holding force of the cylindrical shrink label on the outer peripheral surface of the container increases.

In the labeled container according to the present invention, the sliding layer mixed with the hydrophilicity-imparting agent is formed of an ink mixed with 5 to 15% by weight of the hydrophilicity-imparting agent. To do.

  As described above, the cylindrical shrink label of the present invention increases the holding force to the container while maintaining the sliding characteristics when the container is covered with the hydrophilicity imparting agent by mixing the hydrophilicity-imparting agent into the sliding layer on the inner surface. Therefore, it can be securely attached to a predetermined position of the container. In particular, when the container has a deformed shape having a large-diameter portion, or when the cylindrical shrink label is thin, the effect of preventing displacement is great.

  Hereinafter, a cylindrical shrink label according to an embodiment of the present invention and a labeled container equipped with the same will be described with reference to FIGS. FIG. 1 and FIG. 2 show a state in the middle of mounting the cylindrical shrink label 1 in the present embodiment on the container 2. In this state, the cylindrical shrink label 1 formed by being cut from the long label body 10 through a series of processes as described above is expanded by a labeler opener, and the container is held in an expanded state by the opener. 2 is a state when the cylindrical shrink label 1 is released from the opener after being put on the predetermined position of 2. Therefore, the cylindrical shrink label 1 is in an uncontracted state and is stuck to the outer peripheral surface by water droplets adhering to the outer peripheral surface of the container 2 without receiving external force. It is conveyed, heated, and thermally contracted to adhere to the container 2.

  Such a container 2 is typically a PET bottle. Therefore, the material thereof is polyethylene terephthalate, and the mouth 21 to which the cap 20 is attached, the bottom 22, and between the mouth 21 and the bottom 22. It consists of the formed cylindrical body part 23. The body portion 23 is not a shape having a constant diameter but a shape having a large change in diameter, and a large-diameter portion 24 having a larger diameter relative to the upper and lower regions is formed in the upper half portion. Yes. And the cylindrical shrink label 1 is mounted | worn only to the middle part which is a part rather than the up-down direction full length of the trunk | drum 23. As shown in FIG. That is, the cylindrical shrink label 1 is shorter than the entire length in the vertical direction of the body portion 23 and is attached only to a predetermined region including the large diameter portion 24 of the container 2. The mounting position is a position that floats upward from the bottom portion 22, and therefore, the lower end portion of the cylindrical shrink label 1 is positioned above the bottom portion 22 of the container 2 by a predetermined height. Moreover, in the attachment area | region where the cylindrical shrink label 1 is attached among the trunk | drum 23 of the container 2, the large diameter part 24 is a part with the largest diameter. FIG. 2 shows a cross-sectional view of the large-diameter portion 24. Thus, the unshrinked cylindrical shrink label 1 contacts the large-diameter portion 24 in a state close to line contact.

  As shown in FIG. 2, a total of four folds 25 a, 25 b, 25 c, and 25 d are formed on the unshrinked cylindrical shrink label 1 placed on the container 2. As described above, the long label body 10 is flat as shown in FIG. 3A, and folds 25a and 25b are formed on both side edges thereof. And the label long body 10 drawn | fed out from the roll is return | folded in the middle of a driving | running route. The folding process is a process in which the long label body 10 in the flat state is opened once and is newly folded in a flat state so that both side edges in the flat state are brought close to each other and overlapped. FIG. As shown in FIG. 2, two folds 25c and 25d are newly formed, and a total of four folds 25a, 25b, 25c and 25d are formed along the axial direction together with the original two folds 25a and 25b. . Therefore, the creases 25a, 25b, 25c, and 25d are formed at intervals of about 90 degrees in the circumferential direction. Thus, after the label long body 10 is newly folded in the direction orthogonal to the original flat state to be in a flat state, it is cut into predetermined lengths to form individual cylindrical shrink labels 1. The When the cylindrical shrink label 1 formed with the folds 25a, 25b, 25c, and 25d as described above is expanded with an opener, is put on the container 2 and separated at a predetermined position, the folds 25a, 25b, 25c, and 25d are formed. As a result, the portions between the folds 25a, 25b, 25c, 25d and the folds 25a, 25b, 25c, 25d (portions indicated by symbol S in FIG. 2 and the periphery thereof) come into close contact with the container 2. . 2 and 3, the overlapping portion is denoted by reference numeral 26, and four folds 25 a, 25 b, 25 c, 25 d are formed at locations other than the overlapping portion 26. Note that the return processing is not essential and may be omitted. In that case, two fold lines 25a and 25b are formed.

  The cylindrical shrink label 1 may be a so-called front-printed one printed on the outer surface, but in the present embodiment, a so-called back-printed one printed on the inner surface is exemplified. As shown in FIG. 4, the cylindrical shrink label 1 includes a base film 30, and a display print layer 31 laminated on the inner side (back side) of the base film 30. The background print layer 32 laminated inside the display print layer 31 and the slide layer 33 laminated inside the background print layer 32 are provided, and the slide layer 33 is the innermost layer and is a cylinder. The inner surface of the thin shrink label 1 is formed. The background print layer 32 may be the innermost layer, and the background print layer 32 may be provided with slipperiness to itself become the slide layer 33.

  In the case of back printing, it is preferable that the base film 30 is transparent so that at least the inner display print layer 31 can be viewed from the outside. As the base film 30, for example, various heat-shrinkable films such as polyester film, polystyrene film, polyolefin film, etc. can be used. A uniaxially stretched film that contracts in the main stretching direction can be used, but a biaxially stretched film that contracts in a direction orthogonal to the main stretching direction may also be used. The main stretching direction of the film is the circumferential direction of the cylindrical shrink label 1. Further, the heat shrinkage rate in the main stretching direction of the base film 30 is preferably 20 to 80% and particularly preferably 30 to 80% when immersed in warm water at 90 ° C. for 10 seconds. However, in the case of a front printing configuration in which the display print layer 31 is formed on the outer surface of the base film 30, the base film 30 may be a colored film such as a milky white film. The thickness of the base film 30 is, for example, 10 to 70 μm, particularly 10 to 50 μm, and in particular, when a thin film having a thickness of 10 to 30 μm is used, the stiffness is weak and the holding power to the container 2 is weak. The effect of mixing the hydrophilicity imparting agent described later into the sliding layer 33 is great.

  The display printing layer 31 is a layer printed with characters, designs, etc., and is formed by gravure printing, for example, and acrylic ink is used. Various gravure inks such as urethane type can be used. The ink may or may not contain a pigment, and may be a UV curable ink.

  The background printing layer 32 is a background layer for the display printing layer 31, and this layer is also formed by a printing technique such as gravure printing. The background printing layer 32 is, for example, a white solid printing layer, and is composed of one layer or two or more layers of white ink mixed with a white pigment such as titanium dioxide.

  The sliding layer 33 is formed on the entire inner surface of the cylindrical shrink label 1 and is typically a medium ink layer, and this layer can also be formed by a printing technique such as gravure printing. The medium ink layer is a layer made of a transparent ink containing no colorant, and is excellent in slipperiness with respect to the container 2, particularly a PET bottle. The sliding layer 33 also functions as a protective layer for the display printing layer 31 together with the background printing layer 32. Moreover, you may provide the protective layer which consists of a medium ink layer also in the outer surface of the base film 30, for example.

  The slip property can be evaluated by a wetting index or a dynamic friction coefficient in a wet state. The wetting index is a numerical value of the surface tension (dyn / cm) of the liquid mixture that has been determined to wet the inner surface by applying a series of mixed liquids having different surface tensions in order to the inner surface of the cylindrical shrink label 1. It is measured by the same method as the wetting test method for polyethylene and polypropylene films (JIS K 6768). Further, the dynamic friction coefficient in the wet state is a polyester sheet having a dynamic friction coefficient of 0.45 between the same materials measured by a plastic film and sheet friction coefficient test method (JIS K 7125) as a counterpart material. A method according to JIS K 7125 described above, with a test piece superimposed on the surface of the polyester sheet with a 0.1 ml water drop dropped on the surface of the polyester sheet, a test speed of 500 mm / min, and a friction distance of 150 mm. Is a value measured by. The wetting index is preferably 40 or less, particularly 35 or less, and the dynamic friction coefficient in the wet state is preferably 1.0 or less, particularly preferably 0.6 or less.

  This medium ink is substantially free of pigment, for example, an aqueous resin such as an emulsion in which an acrylic resin, an acrylic copolymer, a polyester resin, a urethane resin, an aqueous polyamide resin, etc. are dispersed in water or water and alcohol. Rosin, ketone resin, vinyl chloride resin, vinyl chloride-vinyl acetate copolymer, acrylic resin, urethane resin, acrylic-urethane copolymer, polyester resin, and other solvents such as toluene, methyl ethyl ketone, ethyl acetate, isopropyl alcohol Examples of the solvent type in which etc. are dissolved are exemplified. In order to improve slipperiness, various waxes such as polyolefin wax such as polyethylene wax, fatty acid amide, fatty acid ester, paraffin wax, polytetrafluoroethylene wax, carnauba wax; silicones such as cyclic silicone; fluorine Various lubricants such as compounds can be added. If necessary, other additives such as thickeners, antifoaming agents, fungicides, water-solubilizing agents may be mixed. As the medium ink, for example, trade name “STR heat resistant CS medium” manufactured by Dainichi Seika Kogyo Co., Ltd. can be used. This medium ink contains an acrylic resin as a resin component and polyethylene wax as a lubricant. Contains. In addition, so that it may be suitable for various printing techniques, such as gravure printing (for example, the viscosity is preferably 10 to 2000 mPa · s, more preferably 20 to 500 mPa · s). Is already volatilized in the state of being formed as a medium ink layer as the sliding layer 33, and therefore the medium ink layer (sliding layer 33) is substantially free of solvent.

Further, a hydrophilicity imparting agent is mixed in the sliding layer 33. The hydrophilicity imparting agent has an effect of increasing the surface tension by reacting with water droplets adhering to the container 2, and the hydrophilic portion is ionic (cationic, anionic, zwitterionic) It is roughly divided into non-ionic ones. A typical cationic structure includes an amine salt type and an ammonium salt type. Typical anionic structures include those represented by molecular formulas such as R—COONa, R—SO ₃ Na, and R—OSO ₃ Na (where R is an alkyl group). A typical example of a zwitterionic structure is an amino acid type having both —NH and —COOH. A typical nonionic structure is a polyhydric alcohol containing a large amount of hydroxyl groups. And as a preferable thing of a hydrophilic property imparting agent, cationic hydrophilic property imparting agents, such as a quaternary ammonium salt, are mentioned. The cationic hydrophilicity imparting agent such as a quaternary ammonium salt is used after being diluted to a viscosity suitable for printing with alcohols such as methanol, ethanol, propanol, isopropanol, isobutanol, and n-butanol. For example, what diluted alkyl ammonium chloride in solvents, such as isopropyl alcohol and methanol, can be illustrated. However, the solvent for diluting the hydrophilicity-imparting agent so as to be suitable for printing is volatilized in the state formed as the sliding layer 33 and substantially not contained, like the solvent for the medium ink described above.

  The mixing ratio of the hydrophilicity imparting agent is determined by the material constituting the sliding layer 33, the kind of the hydrophilicity imparting agent, the thickness of the base film 30, the total thickness of the cylindrical shrink label 1, and the stiffness of the base film 30. For example, it may be 5% by weight or more, depending on various conditions. The mixing ratio of the hydrophilicity imparting agent is a mixing ratio in a state diluted with a solvent so as to be suitable for printing. The hydrophilicity-imparting agent is preferably mixed in an amount that maintains the slipperiness of the inner surface of the cylindrical shrink label 1, but the mixing ratio can be, for example, 15% by weight or less. The degree of maintaining the slipperiness of the inner surface of the cylindrical shrink label 1 is, for example, such that the wetting index of the inner surface does not increase, and the friction coefficient of the inner surface in a wet state, in particular, the dynamic friction coefficient does not increase. In any case, it is preferable that the cylindrical shrink label 1 is mixed while maintaining the slipperiness that can be smoothly covered when the container 2 is covered.

  As an example, a surface active agent (for example, trade name “EXP61004” manufactured by Osaka Printing Ink Mfg. Co., Ltd.) obtained by diluting the sliding layer 33 as a medium ink layer and diluting alkylammonium chloride with isopropyl alcohol as a hydrophilicity imparting agent is used as the medium ink. The change of the holding force of the cylindrical shrink label 1 was measured by mixing and variously changing the mixing ratio. A thin polyethylene terephthalate film having a thickness of 20 μm was used for the base film 30. The test method is as follows. That is, the cylindrical shrink label 1 is cut into a length of 90 mm in the axial direction (MD direction) and a length of 40 mm in the circumferential direction (TD direction) to produce the test piece 40. As shown in FIG. 5, a holding plate 41 in which a PET sheet is attached to an iron plate is prepared. A 10 μl (microliter) water droplet 42 is attached to one side of the test piece 40, and the test piece 40 is put on the PET on the holding plate 41 by the water droplet 42. Paste it on the sheet. Then, the upper part of the test piece 40 protruding upward from the holding plate 41 is gripped by an autograph chuck manufactured by Shimadzu Corporation and pulled upward at a speed of 200 mm / min. taking measurement. It can be said that the greater the holding force, the greater the holding force when the container 2 is covered with the unshrinked cylindrical shrink label 1 as shown in FIG.

  The measurement results are shown in FIG. As shown in FIG. 6, when the mixing ratio of the hydrophilicity-imparting agent is up to 3% by weight, the holding power hardly changes compared to the case where the hydrophilicity-imparting agent is not mixed, that is, the mixing rate is 0% by weight. On the other hand, it was found that when the mixing ratio is 5% by weight, the holding power is greatly increased. Thus, it turns out that holding power improves by mixing a hydrophilicity imparting agent more than a fixed mixing rate. It was confirmed that even when the mixing ratio was 15% by weight, there was no effect on the slipperiness of the inner surface of the cylindrical shrink label 1. That is, even if a hydrophilicity-imparting agent is mixed in the slipping layer 33 by about 15% by weight, the slipperiness of the inner surface, that is, the wetting index and the dynamic friction coefficient in the wet state are not much different from those not mixed. Therefore, by setting the mixing ratio of the hydrophilicity imparting agent within a predetermined ratio range (for example, 5% by weight to 15% by weight), the container 2 after being released from the opener is maintained while maintaining the sliding property of the sliding layer 33. The holding power can be improved.

  As described above, the cylindrical shrink label 1 in the present embodiment can be smoothly inserted into the container 2 by the sliding layer 33 on the inner surface, and the hydrophilicity imparting agent is mixed in the sliding layer 33. Therefore, the surface tension of the water droplets adhering to the outer peripheral surface of the container 2 is increased, and the water drop is reliably held on the outer peripheral surface of the container 2 even after being released from the opener. In particular, the cylindrical shrink label 1 is effective for a thin one having a small rigidity and a weak holding force to the container 2 of about 20 μm (for example, a compressive strength of 5 N or less). Therefore, it is transported to the shrink tunnel without being displaced, and is surely brought into close contact with the predetermined position of the container 2 by thermal contraction. Further, since the contact area with the cylindrical shrink label 1 becomes extremely small in the deformed shape in which the container 2 has the large diameter portion 24 as shown in FIG. 1, the container 2 has such a deformed shape. This is particularly effective, and the cylindrical shrink label 1 can be reliably attached to a predetermined region including the large diameter portion 24 of the container 2.

  In the present embodiment, the sliding layer 33 in which the hydrophilicity imparting agent is mixed is uniformly formed on the entire inner surface, but the hydrophilicity imparting agent is mixed only in a part of the entire region of the sliding layer 33. The remaining region may not be mixed with a hydrophilicity-imparting agent. For example, the entire region of the sliding layer 33 may be partitioned into a hydrophilic region in which the hydrophilicity imparting agent is mixed and a water repellent region in which the hydrophilicity imparting agent is not mixed. When the region is partitioned in this way, the hydrophilic region is positioned at least in a portion in contact with the large-diameter portion 24 of the container 2 or a portion near the top and bottom thereof.

  For example, as shown in FIG. 7A, the hydrophilic region 33a is formed only in the portion of the entire region of the sliding layer 33 (that is, the entire region of the inner surface) that is in contact with the large diameter portion 24 of the container 2, and the remaining other region. Can be the water repellent region 33b. The hydrophilic region 33a can be formed in a strip shape having a predetermined width that is continuous over the entire circumference, that is, in an annular shape. In FIG. 7 and FIG. 8 described later, the hydrophilic region 33a is cross-hatched.

  Further, as shown in FIG. 7B, a strip-like hydrophilic region 33a may be formed over the entire circumference in a portion close to the top and bottom of the portion contacting the large diameter portion 24 of the container 2. .

  Furthermore, the hydrophilic region 33a may have a shape that is not continuous in the circumferential direction as shown in FIG. 7, but a shape that is discontinuous in the circumferential direction. For example, as shown in FIG. 8A, a plurality of hydrophilic regions 33a having a predetermined shape, for example, a rectangular shape may be formed while being spaced apart in the circumferential direction. Similarly, as shown in FIG. 8B, a plurality of hydrophilic regions 33a having a predetermined shape, for example, a triangle, may be formed while being alternately turned upside down in the circumferential direction. In this way, even when a plurality of hydrophilic regions 33a having a predetermined shape are arranged at intervals in the circumferential direction, the hydrophilic regions 33a are formed in a portion in contact with the large diameter portion 24 of the container 2 as in the case of FIG. Alternatively, as in the case of FIG. 7B, it may be formed at positions near the top and bottom of the portion that contacts the large diameter portion 24 of the container 2. When the hydrophilic region 33a is formed in the vicinity of the portion that contacts the large diameter portion 24 of the container 2, depending on the shape of the container 2, for example, with respect to the portion that contacts the large diameter portion 24 of the container 2 It may be formed only in the vicinity of the upper side, or conversely, it may be formed only in the vicinity of the lower side with respect to the portion in contact with the large-diameter portion 24 of the container 2 and is disposed on both the upper and lower sides. You may arrange | position only on one side, without.

  Further, it is particularly effective for the irregularly shaped container 2 having the large diameter portion 24, but is also effective for the container 2 having the body portion 23 having a substantially constant diameter so as not to have the large diameter portion 24, The effect of mixing the hydrophilicity-imparting agent into the sliding layer 33 is not limited to the specific shape of the container 2.
