JP6832748B2 - Neck POP label - Google Patents

Description

The present invention relates to a neck POP label, and more particularly to a neck POP label preferably used in an automatic mounting device in which neck POP labels are fed out one by one and mounted on the neck of a container such as a bottle or bottle.

Traditionally, campaign stickers and pop labels displaying promotional information have been used for sales promotion of various products such as soft drinks, alcoholic beverages, and seasonings that are lined up on display shelves in convenience stores and supermarkets. .. In particular, pop labels are often used for the neck of containers such as bottles and bottles, and insert holes are formed in the sheet piece of the label so that the neck of the container is fitted and locked, or the neck. There is known a neck POP label that forms a cut to fit in.

When using the neck POP label on the neck of a container such as a bottle or bottle, there are few problems when the label is attached to the neck of the container manually (manually), but for example, use an automatic attachment device to attach the label. When automatically supplying one label to the neck of the container and automatically mounting it, the labels are separated one by one from the large number of labels accumulated (loaded) in the stacker and supplied to the neck of the container. It is necessary to do.

However, since the neck POP label has insertion holes and cuts used for mounting, labels are separately supplied one by one from a group of labels stacked and accumulated in the stacker of the label feeding device of the automatic mounting device. At that time, there was a problem that the insertion holes and cuts were caught in each other and the separate supply did not proceed smoothly.

Patent Document 1 discloses a neck hanger label in which a hole for attaching to the neck of a container such as a bottle or a bottle is not penetrated and a flat surface of the label surface (and back surface) is maintained. Further, Patent Document 2 describes a label-forming base material for neck hanging, which is wound in a roll shape so as to partially connect the vicinity of the mounting hole of the cut formed in the peripheral portion of the mounting hole of the label-forming base material. It is disclosed.

However, conventional techniques such as the labels described in the prior art documents described above have not been able to sufficiently prevent the insertion holes and cuts of the stacked labels from being caught by each other.

Since the automatic mounting device processes a large number of labels in a short time, even if the defect rate is small, the operation must be stopped every time a defect occurs, and the potential damage amount increases. Therefore, there is a demand for the development of a neck POP label having a much lower defect rate than the prior art.

In the present invention, when the neck POP label is fitted and locked to the neck of an object to be mounted such as a bottle or a bottle by using an automatic mounting device, the labels loaded on the stacker of the label supply device are loaded one by one. Provided is a neck POP label that can be accurately extended and can prevent labels from getting caught due to insertion holes or cuts during extension. The neck POP label according to the present invention can also prevent jamming during transportation when the label is attached to the object to be attached by the automatic attachment device.

An embodiment of the neck POP label of the present invention will be described below.

FIG. 1 shows a cross-sectional view of the neck POP label 100 according to the embodiment of the present invention.

The neck POP label 100 shown in FIG. 1 is provided with a label body made of a sheet-like base material 102, a pattern / character layer 104 on which a pattern or characters are printed on the label body, and front and back surfaces of the label body. Varnish layers 106, 108 are included to control slipperiness. Note that the thickness is extremely exaggerated in Fig. 1 to make the structure easier to understand.

The material of the sheet-like base material such as the sheet-like base material 102 is not particularly limited, and any material used for labels in the technical field can be used. Examples of materials for sheet-like base materials include paper, synthetic paper, polyolefins such as PP (polyethylene) and PE (polyester), polyesters such as PET (polyethylene terephthalate), PS (polystyrene) and PA (polyester). Rigid resin sheet or the like can be preferably used. The thickness of the sheet-like base material is preferably in the range of 50 μm to 300 μm, more preferably 100 μm to 200 μm.

The color of the sheet-like base material such as the sheet-like base material 102 is not particularly limited, but for example, white, grayish white, gray or the like can be preferably used depending on the material. Further, the sheet-like base material may have translucency (transparent or translucent) depending on the material. It is also possible that the sheet-like base material and the varnish layer are both transparent or translucent, and the neck POP label itself is transparent or translucent.

A pattern / character layer 104 is provided on the front and back of a sheet-like substrate such as the sheet-like substrate 102 by printing a pattern or characters for transmitting information as necessary (to consumers of products, etc.). Has been done. The printing method is not particularly limited as long as it is a method used in the technical field, but for example, a flat plate printing method (offset printing, etc.), an intaglio printing method (engraving intaglio printing, gravure printing, etc.), and stencil printing. The method (silk screen printing, etc.) can be used. Examples of the ink used for printing include ink in which a colorant is dispersed in a resin such as acrylic or cellulose. As such a colorant, inorganic pigments (titanium oxide, carbon black, copper, etc.), pearl pigments, aluminum powder, and the like can be used.

In the embodiment shown in FIG. 1, the pattern / character layer 104 is provided on both sides of the neck POP label, but may be provided on either the front surface or the back surface. Considering that the neck POP label plays a role of transmitting information such as product promotion, it is preferable to provide the pattern / character layer 104 on a surface that is easily visible to consumers or on both front and back surfaces.

Further, in the embodiment shown in FIG. 1, the pattern / character layer 104 is divided into several parts (that is, the entire surface of the sheet-like base material 102 is not covered), which is a sheet-like base material. This is an example corresponding to the partial printing on 102. For example, it is possible to utilize the ground color without printing the same part (for example, white part) as the ground color of the sheet-like base material in the pattern or characters. In another embodiment, as will be described later, the pattern / character layer may cover the entire surface of the sheet-like base material (that is, the pattern or characters may be printed on the entire surface).

The thickness of the pattern / character layer is not limited as long as the effect of the present invention can be exhibited, but can be, for example, in the range of 0.5 μm to 10 μm, more preferably in the range of 1 μm to 3 μm.

The varnish layer such as 106, 108 is applied to the neck POP label or the printed surface of the pattern or characters contained therein, and has a function of imparting slipperiness and abrasion resistance. The material of the varnish layer can be appropriately selected in consideration of the manufacturing method, slipperiness, glossiness, light transmission, designability, and the like. Examples of the material of the varnish layer include OP varnish, oil-based varnish, water-based varnish, UV-curable varnish, and other special varnishes. In view of the above characteristics, a UV curable varnish can be particularly preferably used. Further, the varnish layer may be one to which an auxiliary agent such as a photocurable resin, a photosensitive monomer, rosin or an organic solvent is added. Preferably, the varnish layer is translucent (that is, transparent or translucent so as not to interfere with information transmission by the pattern / character layer, and information can be read from the pattern / character layer below it. May be possible).

Further, in the embodiment shown in FIG. 1, the varnish layers 106 and 108 are single layers on each surface, but in other embodiments, the varnish layers may be composed of a plurality of layers (laminated). The thickness of the varnish layer is not limited as long as the effects of the present invention can be exhibited, but can be, for example, in the range of 0.5 μm to 10 μm, more preferably in the range of 1 μm to 3 μm.

In a preferred embodiment, at least one of the varnish layers on the front and back surfaces of the neck POP label may contain inert inorganic fine particles for the purpose of adjusting slipperiness and the like. The inert inorganic fine particles are preferably selected from silica, calcium carbonate, and silicone particles, and the content thereof is, for example, 1 to 10% by mass in terms of the solid content ratio of the varnish layer.

FIG. 2 shows a cross-sectional view of the neck POP label 200 according to another embodiment of the present invention. The neck POP label 200 is almost the same as the neck POP label 100 in FIG. 1, but has the following differences. That is, on the neck POP label 200 of FIG. 2, the pattern / character layer 204 is printed on only one side of the sheet-like base material 202. Further, although the varnish layers 206 and 208 are provided on both surfaces of the sheet-like base material 202, the varnish layer 206 does not cover all of the sheet-like base material 202. The varnish layer 206 covers the entire pattern / character layer 204. In Fig. 2, the thickness is exaggerated as in Fig. 1.

With the configuration shown in FIG. 2, the abrasion resistance of the pattern / character layer 204 can be ensured, and the slipperiness can be controlled. In other words, if the varnish layer is partially provided to the extent that slipperiness can be ensured (that is, the varnish layer is sufficiently provided at the portion that mainly contacts the roller means and the conveying means of the automatic mounting device. B), the effect of the present invention can be exhibited. Further, the varnish layer can uniformly cover the sheet-like base material as in this embodiment, but in another embodiment, it can be covered so as to be scattered over the entire surface of the sheet-like base material, for example, in a dot shape. The area ratio of the varnish layer covering the sheet-like base material depends on the material of the varnish layer, but can be, for example, 10% or more, more preferably 30% or more. In other embodiments, the varnish layer does not have to cover the entire pattern / character layer.

FIG. 3 schematically shows a configuration example of an automatic mounting device 300 that can suitably use the neck POP label according to the embodiment of the present invention. The automatic mounting device 300 has a stacker (not shown) for loading the neck POP label, a taper jig 304 for tilting and sliding the neck POP label in the stacker, and a neck POP label that has slipped out of the stacker. It includes a transport roller 310 and auxiliary rollers 312, 314 for feeding and transporting, and a transport belt 322 and transport roller 324 for carrying the fed neck POP label.

The loading neck POP label tilted by the taper jig 304 slides out one by one, and its surface (the surface facing upward with respect to gravity in FIG. 3) is gripped by the transport roller 310 and fed out. Therefore, as will be described later, it is important that the surface of the neck POP label has a high coefficient of static friction. Further, the transport roller 310 is preferably made of a material having good grip such as resin or rubber. The auxiliary rollers 312 and 314 assist the feeding, and may be made of a material such as iron, or may be made of resin or rubber in some cases.

The unwound neck POP labels are carried one by one on the transport belt 322 along with the movement of the transport roller 324. Then, the neck POP label is attached to the container 330 carried on another belt conveyor in a timely manner.

In the neck POP label according to the embodiment of the present invention, the coefficient of static friction differs between the front and back depending on the configuration of the varnish layers provided on the front and back, so that the transport performance (ease of feeding and luck) when used in the automatic mounting device It has an excellent effect that the ease of exposure is improved and there is no problem in mounting performance on the mounting target.

More specifically, when loading the neck POP label in the automatic mounting device (in the stacker, etc.), the front surface and the back surface provided with the varnish layer are brought into contact with each other so that the neck POP labels have different electrostatic friction coefficients. By loading on the neck POP label, when the neck POP label is unwound, the insertion holes and cuts are not caught and the labels can be ejected one by one smoothly, making it easier to unwind one by one and reducing problems such as jamming. Played. If the front surface and the back surface of the neck POP label have the same high slipperiness, the slippage between the labels becomes too good, which may cause a problem that loading becomes difficult. On the other hand, when both the front and back surfaces of the label have low slipperiness, there arises a problem that it becomes difficult to feed the labels due to poor slippage between the labels.

Further, since the static friction coefficient is relatively high on the surface of the automatic mounting device on the side in contact with the roller means (usually, this surface is often referred to as the "surface" of the neck POP label), the roller means is concerned. The grip performance is improved, and the effect of feeding and transporting is improved.

On the other hand, the surface of the automatic mounting device that comes into contact with the transport means such as the transport belt (usually, this surface is often referred to as the "back surface" of the neck POP label) has good slipperiness due to the low coefficient of static friction. As a whole, the transport performance is improved.

Here, the coefficient of static friction is the maximum for the stroke by placing a 200 g weight (54 mm x 74 mm) on the label, pulling the weight at a speed of 100 mm / min using a tensile tester, and measuring the test force when sliding. Obtained from the value of test force.

In this case, the coefficient of static friction is calculated by the following formula. This 1.96N is a value corresponding to the weight kilogram corresponding to the weight of the weight (200g).
Static friction coefficient = maximum test force (N) ÷ 1.96 (N)

The coefficient of static friction on the front and back surfaces (that is, the varnish layer) of the neck POP label may satisfy the above-mentioned magnitude relationship, and can be appropriately set depending on the material of the sheet-like base material, the pattern / character layer, and the varnish layer. On the premise that the above magnitude relationship is satisfied, as an example, the static friction coefficient of the front and back surfaces of the neck POP label can be preferably 0.2 or less, more preferably 0.1 to 0.2. The coefficient of static friction of the sheet-like substrate is 0.17 or more, more preferably 0.2 to 0.24. The coefficient of static friction of the pattern / character layer is 0.2 or less, more preferably 0.1 to 0.2.

FIG. 4 shows a plan view of the neck POP label 400 according to an embodiment of the present invention. The neck POP label 400 generally has a rectangular shape with rounded corners, and the label body has an insertion hole 430 for fitting the neck of the object to be mounted and one end at the edge of the insertion hole 430. A pair of left and right first cut lines 410 extending in contact with each other and a pair of left and right first cut lines 410 that touch and intersect the end opposite to the side that is in contact with the edge of the insertion hole 430 of the first cut line 410. It has two notch lines 420a and 420b. The first cut line 410 and the second cut lines 420a and 420b have uncut portions, respectively. Further, the second cut lines 420a and 420b may further have tear prevention portions (that is, short cut lines provided at an angle) at the upper end and the lower end, respectively.

In a preferred embodiment, the first cut line 410 and / or the second cut lines 420a, 420b may be provided with uncut portions intermittently. In a more preferred embodiment, as shown in the lower part of FIG. 4, the first cut line 410 has a total of two left and right places, and the second cut lines 420a and 420b have a total of three upper, middle and lower places. Can have an uncut portion of. In other embodiments, the number of uncut portions may be less or more than that shown in FIG.

In a preferred embodiment, as shown in the lower part of FIG. 4, the positions of the uncut portions provided in the first cut line 410 are the end tangent to the insertion hole 430 and the end tangent to the second cut lines 420a and 420b. It can be near the middle of.

In a preferred embodiment, as shown in the lower part of FIG. 4, the positions of the uncut portions provided on the second cut lines 420a and 420b are the central position in contact with the first cut line 410 and the central position. It can be near the middle between the end in contact with the tear prevention portion. In other embodiments, the position of the uncut portion may be different, or the position and number of uncut portions may be different between the second cut line 420a and the second cut line 420b.

The shape of the insertion hole 430 shown in FIG. 4 is an ellipse as an example, but any shape (circle, quadrangle, rhombus, hexagon, etc.) can be taken. Preferably, the insertion hole 430 may have an elliptical shape that is long in the direction connecting the contact point with the first notch line 410. In another embodiment, instead of providing the insertion hole 430, a portion of the same shape that can be easily punched out by a perforated dividing line, a cut line having a short uncut portion, or the like may be provided. In yet another embodiment, the insertion hole 430 may be provided with a protrusion for locking to the neck of the object to be mounted.

It is preferable that at least a part of the inner diameter (hole diameter) of the insertion hole 430 is smaller than the diameter of the neck of the object to be mounted (such as a bottle container with a cap), for example, the cap diameter of the bottle container with a cap. The hole diameter (minor diameter in the case of an ellipse) of the insertion hole 430 is preferably in the range of 75% or less, preferably 75% or less and 25% or more of the diameter of the neck of the object to be mounted, for example, the bottle cap. If the hole diameter is more than 75% of the diameter of the neck, when inserting the label into the neck of the object to be attached, the force is not transmitted well to the label, the hole diameter is not wide enough and it does not work well on the neck, or it does not work on the neck. There may be a problem that the attached label is easily removed. On the other hand, if the hole diameter is less than 25% of the diameter of the neck, too much force may be applied during insertion depending on the type of automatic mounting device, which may lead to damage to the label.

The lengths of the first cut line 410 and the second cut lines 420a and 420b are not particularly limited, and have a length that allows the neck to be inserted when mounted on the neck of the object to be mounted. You just have to.

The length of the uncut portion of the cut line (the length in the direction along the cut line) is 0.3 mm (breaking force (when the sheet-like base material is woodfree paper. The same applies to this paragraph below): Approximately 1N ) Or more, more preferably 0.3 mm (breaking force: about 1N) to 0.5 mm (breaking force: about 4N), or preferably 0.3 mm (breaking force: about 1.1N) to 0.6 mm (breaking force: about 1.1N). Force: may be about 5.3N). If the length is less than 0.3 mm, there may be a problem that the uncut part is easily cut. On the other hand, if the length is larger than 0.5 mm, the uncut portion cannot be cut well when the label is attached to the neck, and there is a risk of insertion failure or breakage of the label.

In a preferred embodiment, the uncut portion of the first cut line 410, which will receive the force first at the time of mounting, may be longer than the uncut portion of the second cut lines 420a, 420b. That is, while preventing the uncut portion of the first cut line 410 from breaking during transportation, the second cut line 420a and 420b are mounted so that the uncut portion is broken without any problem because the force is applied first during mounting. It may be possible to break at a later time.

FIG. 5 schematically shows a state in which a neck POP label such as the neck POP label according to the above-described embodiment is attached to an object to be attached, which is a bottle.

As the length of the uncut portion in the preferred embodiment, the uncut portion of the first cut line 410 is 0.4 mm (breaking force (when the sheet-like base material is woodfree paper; the same applies hereinafter in this paragraph): about 2.5. It can be in the range of N) to 0.5 mm (breaking force: about 4N), more preferably in the range of 0.45 mm (breaking force: about 3N) to 0.5 mm (breaking force: about 4N). Further, the uncut portion of the second cut lines 420a and 420b is in the range of 0.3 mm (breaking force: about 1N) to 0.4 mm (breaking force: about 2.5N), more preferably 0.3 mm (breaking force: about 1N). It can be in the range of ~ 0.35 mm (breaking force: about 2N). In another preferred embodiment, the uncut portion of the second cut lines 420a, 420b is 0.51 mm (breaking force: about 4.0 N) to 0.66 mm (breaking force: about 6.0 N) for manufacturing stability of the neck POP label. ), The uncut portion of the first cut line 410 may be longer than that and 0.66 mm (breaking force: about 6.0 N) or less. In order to measure the length of the uncut portion, it is preferable to use an SEM (scanning electron microscope) in order to prevent the label surface from being disturbed by light reflection. In yet another embodiment, the width of the cut line is widened, the width of the uncut portion (that is, the length along the direction perpendicular to the direction along the cut line) is similarly adjusted, and the breaking force is adjusted. May be controlled.

By changing the size of the uncut portion as described above, it is possible to control the breaking force of the uncut portion when the label is attached. Here, as shown in FIG. 6, the breaking force value is obtained by preparing a test piece having one uncut portion for one cut line and using a tensile tester to cure both ends of the uncut portion. It can be obtained as a test force (N) at which the test piece breaks when pulled at a constant speed of 0.5 mm / min after being fixed with a tool. When there are a plurality of uncut portions for one cut line, the size and breaking force of the uncut portions can be measured for each of them.

FIG. 7 shows a plan view of the neck POP label 700 according to another embodiment. The neck POP label 700 includes a first locking portion 702, a second locking portion 704, and a peripheral portion 706. In FIG. 7, the solid line separating those parts means an unconnected boundary (eg, a notch line). Preferably, by separating the first locking portion 702 and the second locking portion 704 from the peripheral portion 706 in a curved line in this way, a force is applied at the time of mounting and the neck POP label is torn along the division. It is thought that can be avoided.

The first locking portion 702 and the second locking portion 704 have a trapezoidal shape in which a part of the side is a concave curve, and each has a peripheral portion 706, a root connection portion 712, and a root. It is permanently connected via the connection site 714. In other words, the connecting part is a part that is not separated (for example, not cut by a notch line). In Fig. 7, solid arrows are used to indicate the "connection site".

When the neck POP label 700 is attached to an object to be attached (such as a container such as a bottle or bottle) having a neck, the periphery of the root connection portion 712 and the root connection portion 714 is broken or bent, so that the first contact is made. The stop portion 702 and the second locking portion 704 are configured to sandwich the neck of the object to be mounted fitted in the neck POP label 700.

The first locking portion 702 and the second locking portion 704 are connected to each other via the first temporary connecting portion 720. At the time of mounting, the first temporary connection portion 720 receives a force and breaks, so that the neck portion of the object to be mounted can be fitted.

The first locking portion 702 and the peripheral portion 706 are connected not only by the permanent root connection portion 712 but also by the second temporary connection portions 732a and 732b. Further, the second locking portion 704 and the peripheral portion 706 are connected not only at the permanent root connection portion 714 but also at the second temporary connection portions 734a and 734b.

In a preferred embodiment, the second temporary connection sites 732a, 732b, 734a, 734b are also forced to break during mounting, but can be made to break later than the first temporary connection site 720 breaks. .. For example, the force (breaking force) required to break the first temporary connection part 720 is made larger than the breaking force of the second temporary connection part 732a, 732b, 734a, 734b (that is, the part that receives the force first). It may be configured so that it is less likely to break. The first temporary connection portion 720 connecting the tips of the first locking portion 702 and the second locking portion 704, which are configured to stand up at the time of mounting, receives a force during transportation and breaks before mounting. Since it is a part that is easily lost, by adopting a structure in which the first temporary connection part 720 is resistant to breakage, it is possible to suppress unwanted breakage during transportation, and both mounting performance and transfer performance can be achieved. The magnitude of the breaking force is measured at each temporary connection site. That is, in the example of FIG. 7, the breaking force of any one of the second temporary connection sites 732a, 732b, 734a, and 734b is smaller than the breaking force of the first temporary connection site 720. ..

To adjust the breaking force of the temporary connection part, for example, adjust the length of the temporary connection part as an uncut part in the cut line, or make a crease or perforation in the temporary connection part in advance. It can be done by making it brittle by squeezing.

The breaking force of the temporary connection portion can be in an appropriate range depending on the material of the sheet-like base material. As an example, the breaking force of the temporary connection portion can be preferably set in the range of 1N or more and 10N or less, more preferably in the range of 1N or more and 7N or less, and even more preferably in the range of 1N or more and 6N or less. In another embodiment, the breaking force of the temporary connection portion may be set to a range other than this.

Was performed using. As the printing ink, an offset UV ink (process ink) manufactured by T & K Co., Ltd. was used to form a pattern / character layer having a thickness of about 1.5 μm. Then, FD carton manufactured by Toyo Ink Co., Ltd. was used as the surface varnish, and the surface was coated with a thickness of about 2.0 μm.

Similarly, print the back side of high-quality paper on the other side (back side) so that the thickness is about 1.5 μm, and use FLASHDRY manufactured by Toyo Ink Co., Ltd. as the back side varnish. It was coated with a thickness of about 2.0 μm.

The above-mentioned high-quality paper was cut out by hanging it on a flexible pinnacle die to prepare a label having the shape shown in FIG. The label size was 74 x 60 mm, and the shape of the insertion hole was elliptical with a major axis of 30 mm and a minor axis of 10 mm. The length of the first cut line extending from the insertion hole was 5 mm, and the length of the second cut line extending from the first cut line was 40 mm (straight part). Diagonal cuts with a length of 3 mm were also provided at both ends of the second cut line to prevent tearing. At that time, both the first cut line and the second cut line were cut so that there were no uncut portions.

[Example 2]
A label was prepared in the same manner as in Example 1. However, the uncut portions shown in FIG. 4 were provided with 0.3 mm × 1 for each of the first cut lines and 0.3 mm × 3 for each of the second cut lines.

A label was prepared in the same manner as in Example 2. However, the length of the uncut portion of the first cut line was set to 0.5 mm, and the length of the uncut portion of the second cut line was set to 0.3 mm each.

[Comparative example 1]
A label was prepared in the same manner as in Example 1. However, the label was not covered with varnish on the front and back.

[Comparative example 2]
A label was prepared in the same manner as in Example 1. However, the back surface was not coated with varnish, and a label having a coefficient of static friction on the front surface lower than that on the back surface was produced.

(Evaluation methods)
Transport performance: 500 labels are stacked on the stacker part of the automatic mounting device (Toppan TDK Label Neck POP Labeler, product name "TLN-800"), and the labels are fed out at a speed of 60 m / min to see if there are any abnormalities. confirmed.
Wearability: The label drawn out from the stacker of the automatic mounting device was mounted on a PET bottle with a capacity of 500 ml, and the label was normally hung on the neck of the PET bottle, and it was confirmed that there was no tearing.

The meanings of the symbols indicating the evaluation are as follows.
〇: Non-defective rate 99% or more, ×: Non-defective rate less than 99% 90% or more, XX: Non-defective rate less than 90%

(Evaluation results)
The characteristics of the neck POP labels of Examples 1 to 3 and Comparative Examples 1 and 2 and the evaluation results are summarized in the table below.

As shown in the above table, in Examples 1 to 3, there were no problems in both the transport performance and the mounting performance, and the comprehensive evaluation was excellent.

On the other hand, in Comparative Example 1, the transport performance was worse than that in Example. This is because the label lacks a varnish layer, so it is affected by the curl and deflection of the label loaded in the stacker, and the label insertion holes and notch lines get caught and jamming occurs. It depends.

In Comparative Example 2, since the varnish layer was lacking on the back surface, some slippage occurred between the transport roller of the automatic mounting device and the label surface (so-called “abare”), and the transport performance was poor.
