Description

There is an application for exception to loss of novelty

TECHNICAL FIELD The present invention relates to a label to be affixed to merchandise or packaging (hereinafter referred to as "merchandise, etc.") to be sold.

In retail stores such as supermarkets and mass retailers (hereinafter referred to as "retail stores"), when discounting products for reasons such as the expiration date is approaching, discounted products are used to distinguish them from regular priced products. Labels or tapes (hereinafter referred to as "labels, etc.") that certify that there is a product may be affixed to the product.
In addition, depending on the size and quantity of the purchased product, in order to prove that the product has been purchased, a label may be attached to the product so that it can be determined at a glance that the product has been purchased.

However, there have been fraudulent purchases where discount labels are peeled off old products that have been discounted and re-attached to new products of the same type that are sold at regular prices as if they were discounted products. It happens frequently.
Another fraudulent practice is to purchase a low-priced item, peel off the purchased label, return to the sales floor, and re-attach it to a more expensive item.

In order to solve these problems, conventionally, there have been disclosed seal technologies that prevent unauthorized replacement.
For example, the technology related to the sticker for preventing unauthorized re-sticking in reference 1 is characterized by forming a pair of V-shaped notches for breakage in a sticker piece whose sticking surface is coated with an adhesive.

To summarize the technique of Patent Document 1, the seal can be used as a proof of purchase by attaching the seal piece to an object to be adhered.
Here, as shown in FIG. 11, the seal piece (a) is formed with a breaking notch (b) extending from the seal surface to the sticking surface. More specifically, a pair of V-shaped breaking cuts (A) are formed in the width direction at substantially the center position of the seal piece (A). When the sticker piece (A) attached to the adhesive is peeled off from the end, the V-shaped part (C) of the cut (B) for breaking remains attached to the adhesive and is used for breaking. Breaking stress is generated at the cut position (d) and the seal is broken.
Therefore, it cannot be reused, and illegal re-adhering acts such as re-adhering to unpaid products are prevented.

On the other hand, in recent years, for the purpose of reducing marine plastic waste, so-called shopping bags have been charged at retail stores and the like. Along with this, consumers are starting to bring their own eco-bags and personal baskets when shopping, and this is becoming widely established.
There are a wide variety of eco-bags and personal baskets brought in this way, and store employees have no choice but to recognize that the products in them have already been purchased. However, in recent years, there have been many cases of fraudulent use of this point, such as returning to the sales floor after purchase, putting unpaid items in eco-bags or personal baskets, and taking them away.

In the past, when plastic shopping bags were provided free of charge, this kind of fraud was deterred to some extent because the opening of the plastic shopping bag was taped off at the time of checkout, making it difficult to put items inside the plastic shopping bag. There is Therefore, an increasing number of retail stores and the like are taking measures such as attaching labels to the handles of eco-bags and personal baskets.

However, if the adhesive such as the label remains on the consumer's personal belongings such as an eco-friendly bag or a personal basket, so-called adhesive residue, it is unpleasant to touch and the dirt accumulates and becomes unsanitary. Therefore, there was a problem that it became a cause of complaints from owners of eco-bags and personal baskets.

Therefore, conventionally, in a seal for preventing unauthorized re-sticking, a technique using a re-peelable or weakly adhesive adhesive that hardly leaves an adhesive residue on the sticking object even if the sticker is peeled off has been disclosed.
For example, the technology relating to the seal of Patent Document 2 is characterized by forming a re-sticking prevention cut (G) on a seal piece (F) to which a weak adhesive layer is temporarily adhered.
Generally speaking, the seal can be easily peeled off without leaving any adhesive residue after purchase by applying a weak adhesive to the back side of the seal piece.
Also, the re-sticking prevention cut (g) has a diamond-shaped configuration as shown in FIG. As a result, when the sticker is peeled off, it is torn starting from the re-sticking prevention cut (ki), so that the peeled seal cannot be reused and illegal sticking can be prevented.
Here, at the upper and lower corners of the rhombus of the re-sticking prevention cut (G), an uncut portion (H), which is a portion where the cut is interrupted, is left. Since the uncut part (h) is provided, the seal piece (f) can be peeled off without damage while maintaining the integrity of the whole, so it is possible to prevent damage to the attached item. It is said that there is

Focusing on the ease of tearing at the time of peeling, in the technique of Patent Document 2, the uncut part (h) at the time of peeling is the cut for preventing re-sticking. The end of one of the sides (Q) and the opposite end (Q') of the other side are spaced apart by a predetermined distance. Therefore, if the seal piece peels in the longitudinal direction (right and left direction of the rhombus), even if there is an uncut portion (h), it is easy to peel off between the ends (ke, ke') where stress is likely to concentrate. cracks and breaks easily.

JP-A-7-146651 JP 2014-235230 A

However, with the technique of Patent Document 2, a problem arises when the seal piece is peeled off in an oblique direction. That is, in the case of oblique detachment, the stress vector generated at the end of the rhombus is directed in a different direction from the opposite end. Therefore, depending on the peeling angle, the seal piece is less likely to tear than when peeled in the longitudinal direction, and peeling is possible while maintaining the original shape.
This problem is the same even in the case of Patent Document 1.

On the other hand, in the case of affixing to a large product such as a box of home electric appliances in a home appliance mass retailer, the label or the like to be affixed may also be long. In this case, when pasting, it is pulled sideways to prevent wrinkles, and when pasting on a box, it is pasted on the top surface and then stretched to straddle the sides. .
Also, when using a roll-wound label or the like, it is necessary to pull it out with a predetermined force when it is fed out from the roll. In addition, when cutting to a specific length, the material is pulled in the longitudinal direction and pressed against the cutter, or twisted along the perforation line.
Thus, when the label or the like is used, it is used in such a manner that a tensile load acts on it in the longitudinal direction.

In this respect, a label using a removable or weakly adhesive adhesive is easier to remove cleanly without breaking the base material of the label than a label with a strong adhesiveness. On the other hand, this feature is also a drawback. Therefore, in a label or the like using a removable or weakly adhesive adhesive, it is common to make the interval between slits such as cuts for re-sticking prevention as narrow as possible to facilitate breakage.

However, when a tensile load is applied in the longitudinal direction of the label or the like during use as described above, if the gap between the slits is too narrow, regardless of which direction the gap between the slits faces, There is a problem that even a small amount of stress can easily cause breakage, making it unusable.
Although Patent Document 1 uses a weakly adhesive adhesive, no study has been made on this point.

The present invention has been made in view of the above-mentioned problems, and its object is to provide a tape that is strong against tension in the longitudinal direction and that can be reliably broken when peeled off from an adhered object. To provide a label with a slit which can remove a residual piece after being broken from an object to be stuck without leaving any adhesive residue.

The means adopted by the inventors to solve the above problems are as follows.
(basic configuration)
The label with slits of the present invention has a base material and an adhesive layer, and has a basic structure in which a slit is formed to penetrate them in the thickness direction. As long as it has these configurations, it also includes those that are arranged in a plane and those that are wound in a roll.
Note that the slits include not only slits without intervals in the width direction, but also slot-shaped slits having a predetermined width.

When it is configured to be arranged in a plane, it can be stored without being bulky by stacking it in a plane, and since it can be peeled off in a state where it has already been cut into a predetermined shape, the sticking work is easy.
On the other hand, when it is wound into a roll, it can be unrolled from the roll and cut to an arbitrary length, and the size to be used can be appropriately adjusted according to the size of the product or the like. In addition, when the configuration is such that no release paper is used, no dust is generated and it is environmentally friendly.

(Configuration of base material)
In the basic configuration, the substrate has a longitudinal direction and a lateral direction. More specifically, the slitted label alone in use may have a longitudinal direction and a lateral direction, and the planar shape and size are not particularly limited.

By arranging the shape of the substrate so that it has a longitudinal direction and a lateral direction, when it is intended to be peeled off and illegally reused, it can be removed from the lateral direction or its corners in the longitudinal direction or oblique direction. It can be guided to be peeled off, and can be prevented from being peeled off while maintaining its original shape.

(Structure of adhesive layer)
Further, the adhesive layer is peelable so as not to remain on the adhered object when peeled, and is formed on at least a part of one surface of the base material.
Here, the phrase “can be peeled off so that it does not remain on the object to be adhered when peeled off” does not mean that the adhesive does not remain on the object to be adhered at all. This includes cases where the label can be easily removed and cases where it does not substantially impair the quality of the object to which it is applied.

The peelable adhesive can be selected in consideration of adhesive strength and chemical adhesion compatibility with the adhered object. As a result, when the adhesive is peeled off from the object to be applied, the adhesive residue does not remain on the surface of the object to be applied, or even if it does occur, it does not adhere in large amounts.

(Configuration of slit)
On the other hand, the slit is configured as follows.
That is, the slits are formed in the longitudinal direction in a region inside the contour line of the base material, and in the longitudinal direction slit in the region between the longitudinal slit and the contour line in the longitudinal direction of the base material. and a slanted slit formed slantingly with respect to the slit.
Forming in the longitudinal direction means forming in the same direction as the longitudinal direction of the outline of the substrate when viewed as a whole. However, it does not exclude that a part includes a portion extending in the lateral direction, and it also includes those having a plurality of longitudinal slits.

In addition, the inclined slit is formed so that one end thereof is separated from the longitudinal slit and the other end is separated from the profile line in the longitudinal direction of the base material, and a plurality of the inclined slits are arranged side by side along the longitudinal slit. It is
A plurality of inclined slits arranged along the longitudinal slit means that there are a plurality of inclined slits arranged along the longitudinal slit. However, it is not excluded that some inclined slits not along the vertical slits are included.

With respect to the direction of inclination of the inclined slit, the expression that the inclined slit is inclined with respect to the longitudinal slit means that the inclined slit is 180 degrees with respect to the tangential direction of the portion of the longitudinal slit that is closest to the end of the inclined slit. It means that it is inclined at any angle up to However, it is sufficient that a part of the slanted slit is slanted, and the slanted slit is not limited to being linear and the whole being slanted at a constant angle.
By forming the oblique slit obliquely with respect to the longitudinal slit, the peeling direction approaches the direction perpendicular to the oblique slit not only in the longitudinal direction but also in the oblique direction. Therefore, the load acts in the direction of opening the inclined slit, and the stress concentrates on both ends of the inclined slit, so that it can be easily broken.
Also, during tensioning, the tensile load does not act perpendicularly to the inclined slit, but acts at a constant angle. There is no concentration of stress at both ends of the

With respect to arranging a plurality of the inclined slits in parallel, the presence of the plurality of inclined slits along the longitudinal slit allows the openings of the inclined slits to open evenly with respect to the tension, and acts on both ends of the inclined slits. can disperse stress.
In addition, by having a plurality of slanted slits, the openings of the slanted slits are evenly opened when the label is pulled, and the slitted label as a whole stretches well.
At the time of peeling, since there are a plurality of inclined slits, even if one of the inclined slits is peeled cleanly, one of the remaining inclined slits will be broken, and the entire label with slits will be broken. , making it easier to break.

(Action of slit)
Here, the action of the longitudinal slit and the inclined slit will be described in detail.
In general, when a label or the like having a longitudinal direction and a lateral direction is pulled in the longitudinal direction, it is stretched in the longitudinal direction due to the elasticity of the material. Elongation due to pulling is inversely proportional to the cross-sectional area (substantially equivalent to the width in the lateral direction since the thickness of the label is very small), so the narrower the width, the better the elongation.
In the present invention, the widthwise direction is divided into a plurality of parts due to the presence of the longitudinal slit. As a result, the width of the base material in the transverse direction is apparently reduced, so that the elongation is relatively large under the same tensile load. In addition, by arranging the independent inclined slits that are not connected to any of the divided areas, the inclined slits open evenly, and thus the area is well stretched.

In this regard, in the case of a material or shape that does not stretch much under the same tensile load, if you apply the slit label with a pin, the tensile load will be applied to the inclined slit closest to the part pinched with your fingers. In a short period of time, a large stress is generated at both ends of the inclined slit as an impact load, causing it to break.
However, if each slanted slit stretches evenly and the entire label with slits stretches relatively well, the load acting on the slanted slit is not the impact load because the elongation causes the slanted slit to be stretched for a long time. , like a static load. Therefore, the stress generated at both ends of the inclined slit closest to the part pinched with fingers is reduced compared with the impact load that acts when the elongation is small. In addition, since the inclined slits are evenly opened, a uniform stress is generated at both ends of each inclined slit, and the stress is not concentrated at the ends of some of the inclined slits.

By the way, adhesives generally require a larger load in order to be peeled off in a short time, but have the property of being peeled off with a weak force if peeled off slowly.
In the case where the label with slits is wound into a roll, when it is unwound from the roll, the front end in the longitudinal direction is picked up by fingers and pulled out, so that the central portion of the short side on the front end becomes a load point. On the other hand, the other end side can be seen as a fixed end due to a predetermined viscous resistance because the entire short side is the boundary line of peeling from the part wound in a roll, but it is actually a load point. is pulled, the other end side is peeled off one by one.

Based on this, in the present invention, since the whole stretches relatively greatly as described above, even if it is unwound vigorously, the change in the load applied to the boundary line of peeling from the wound part in the roll shape will change with time. gradually become slack. As a result, the force required for peeling from the rolled portion, that is, the tensile load can be reduced, and the stress generated at the end of each inclined slit is also reduced.

Moreover, when the label with slits is wound in a roll shape, it is necessary to cut off the fed portion to a predetermined length. If there is no longitudinal slit, the reaction force against the tensile load concentrates near the center of the short side of the boundary line (the opposite side corresponding to the part pinched with fingers), and near both long sides of the boundary line. becomes relatively small. Therefore, unless the extended portion is largely twisted or obliquely displaced, a crack on the long side, which serves as a starting point for cutting, does not occur. Alternatively, the tip must be pinched at either end in the longitudinal direction and twisted or shifted obliquely.
In this way, excessive force is applied to the ends of the slanted slits, or stress is locally concentrated, resulting in rupture of the slanted slits.

However, in the present invention, since stress is generated along the divided regions, there is a uniform reaction force or a relatively large reaction force in the vicinity of both long sides at the boundary line of peeling from the roll body, which is regarded as the fixed end. Occur. For this reason, by slightly twisting or obliquely shifting the portion that is pulled out while being lightly pulled, cracks on the long sides, which serve as starting points for cutting, are likely to occur. This is more conspicuous when perforation lines, notches, or the like are formed.
Therefore, no unnecessary force is applied to the ends of the inclined slits, and stress is not concentrated on either end of the inclined slits.

Furthermore, in detail about the effect of arranging the vertical slit and the inclined slit under a predetermined condition, in the present invention, the inclined slit is formed so that one end thereof is spaced apart from the vertical slit. The one end and the vertical slit are in a state in which the one end of the inclined slit and the line portion of the vertical slit are separated from each other with a predetermined gap.

If the end of the slanted slit is connected to the longitudinal slit or profile line, a large stress is concentrated on the end of the slanted slit that is not connected when the slanted slit is pulled, so that the slanted slit is easily broken by pulling. .
However, in the present invention, one end of the inclined slit is spaced apart from the longitudinal slit and the other end is spaced from the longitudinal outline of the substrate, so that stress is not applied to either end. It prevents me from concentrating.

On the other hand, when peeling off the attached label with slits, it is difficult to imagine peeling from the ridge line in the longitudinal direction in the lateral direction. For this reason, possible aspects are the direction of peeling in the longitudinal direction from the ridgeline in the width direction and the direction of peeling in the oblique direction from the four corners.

When peeling in an oblique direction, a vector stress that causes cracks in the same direction as the peeling direction is generated at both ends of the tilted slit that is closer to the direction perpendicular to the peeling direction. In this case, although the slanted slit and the profile line or longitudinal slit are separated by a predetermined distance, the distance from the edge of the slanted slit to any part of the profile line or longitudinal slit is any angle of peeling. Even so, it is relatively close. Therefore, it is easy to break between both ends of the inclined slit and an arbitrary portion of the outline or the vertical slit.

In addition, when peeling in the longitudinal direction, it is actually impossible to peel exactly parallel to the longitudinal direction, and the peeling is always performed partially at a slight angle. Therefore, even in the case of peeling in the longitudinal direction, the distance from the end of the inclined slit to the outline or any part of the longitudinal slit is relatively short, so the end of the inclined slit and the outline or the longitudinal slit It will be easily broken between any part of

As described above, even if the stress generated at the edge of the inclined slit during peeling is a vector in any direction, the distance between the edge of the inclined slit and the vertical slit is short, so the both ends of the inclined slit and the outline or It will easily break between arbitrary parts of the longitudinal slit.
In this regard, since the other end of the inclined slit is spaced from the longitudinal outline of the substrate, the other end has the same effect.

As described above, by providing the vertical slit and the slanted slit in the present invention, the entire label with slits can be stretched relatively well, and the stress generated in the slanted slit is uniform. As a result, although it is difficult to break against a tensile load during use, it tends to break easily when peeled off for reuse.

(Means by other configurations)
Among the means for solving the problems of the present invention, those based on the basic configuration are as described above, but the following means can also be used in the present invention.
As an example, in the case of a configuration in which a label with slits is wound in a roll, the inclined slit can be inclined so that one end on the side of the outline in the longitudinal direction of the base material faces the front end of the roll. However, it is not excluded that all or part of the slanted slit is slanted so that the other end on the side of the longitudinal slit is oriented toward the leading edge of the roll.

In the structure wound in a roll, when the inclined slit is inclined so that one end of the base material on the outline side in the longitudinal direction faces the roll tip side, from the center of the tip, which is the load point, the nearest The difference in distance to both ends of the inclined slit becomes smaller.
Then, due to the component of the tensile load in the direction perpendicular to the inclined slits, the nearest inclined slits are deformed so as to open evenly, and the regions defined between the adjacent inclined slits are also uniformly displaced accordingly. This is propagated sequentially, and the entire plurality of inclined slits are uniformly deformed.
This makes it easier for the whole to stretch more evenly, and the stress generated at the ends of the plurality of inclined slits also becomes more uniform. Since the component in the direction perpendicular to the inclined slit is part of the tensile load, the stress does not immediately concentrate on both ends of the inclined slit.

Also, the substrate can be substantially rectangular.
As a result, it is possible to increase the effect of guiding the peeling from the corner in the longitudinal direction or oblique direction.

Regarding the formation direction of the vertical slit, it is also possible to form along a line connecting the centers of the profile lines in the lateral direction of the base material. However, it is not necessarily limited to being arranged in a straight line or along the center line.
When formed along the line connecting the centers of the contour lines in the lateral direction of the base material, the divided regions on both sides have the same width, so that the stress at the time of pulling can be more evenly distributed. , even during peeling, the easiness of breakage is uniform for each peeling direction.

At this time, it is possible to form the vertical slits so as not to be interrupted between at least one adjacent inclined slits. However, it does not exclude the case where it is partially cut off or the longitudinal slit is intermittent.
When the longitudinal slit is formed so that it is not interrupted between at least one adjacent inclined slits, when peeling in the oblique direction or the longitudinal direction, the ends of the inclined slits and the edges of the inclined slits are separated in a wider peeling direction. Cracks tend to occur toward the unbroken portion of the longitudinal slit, ie, the slit portion.

As for the arrangement of the slanted slits, the slanted slits can be arranged only on one side of the longitudinal slit or arranged on both sides.
If the slanted slits are arranged on both sides of the vertical slit, the stress generated in both divided regions becomes more uniform. Also, during peeling, the inclined slits are easily broken in a wider range of peeling directions and peeling angles.

On the other hand, regarding the arrangement of both ends of the inclined slit, at both ends of the inclined slit, the one end on the outline side in the longitudinal direction of the base material is closer to the longitudinal slit than the distance between the one end on the longitudinal slit side and the longitudinal slit. It is possible to increase the distance from the outline. However, it is not excluded that the distance between one end of the substrate on the side of the contour line in the longitudinal direction and the contour line is smaller than the distance from the vertical slit in some cases.
When the distance between one end on the side of the profile line in the longitudinal direction of the base material and the profile line is larger than the distance between the one end on the side of the vertical slit and the profile line, the longitudinal section at the inclined slit is removed during peeling. The end portion from the slit is more likely to break. In addition, since the distance between one end on the outline side and the outline is large, it becomes difficult to tear when pulled.

In addition, the plurality of inclined slits can all have the same inclined direction, but it is not excluded that the inclined direction has a different angle for each inclined slit.
When all of the plurality of slanted slits are slanted in the same slanting direction, the divided regions stretch evenly throughout when pulled, and the stress generated in the divided regions becomes more even.

Moreover, although it is possible to make the distance between a plurality of inclined slits constant, it is not necessarily limited to making the distance between all the inclined slits constant.
When the distances between the plurality of slanted slits are constant, the stress generated in both divided regions becomes more uniform regardless of the positions of the slanted slits.

In the present invention, when the slit label is pulled taut in the longitudinal direction, the tensile load does not act perpendicularly to the oblique slit, but acts at a certain angle. The component in the direction of opening the slit is reduced, and the stress is not concentrated on both ends of the inclined slit. Therefore, it has the effect of being strong against tension in the longitudinal direction.

Regarding the provision of the vertical slit and the inclined slit, the slits in the label with slit are formed in the longitudinal direction in the region inside the outline of the base material, and In the region between the lines, the label is composed of inclined slits that are inclined with respect to the longitudinal slits, and by arranging a plurality of the inclined slits along the longitudinal slits, the entire label with slits stretches relatively well. . Due to the elongation, the time during which the load is applied is elongated, so the load acting on the inclined slit becomes like a static load. Therefore, the stress generated at both ends of the inclined slit is reduced.

In addition, when the label with slits is wound into a roll, the entire label with slits stretches relatively well, so that the force required when peeling from the roll, that is, the tensile load, is small. The stress generated at the end of each inclined slit is also reduced.

Furthermore, when cutting off the paid-out portion to a predetermined length, the tensile load is evenly transmitted along the divided area in the pulled state, and the peeling boundary line from the roll body, which is the fixed end, is even or near both ends. A reaction force is generated. Therefore, by slightly twisting or tilting the part that is pulled out while being lightly pulled, cracks on the long side that can easily be cut off will occur, resulting in unnecessary excess at the end of the inclined slit. I can't apply force.

In addition, regarding the arrangement of the longitudinal slit and the slanted slit, one end of the slanted slit is spaced from the longitudinal slit and the other end is spaced from the longitudinal outline of the base material. It prevents the stress from concentrating on that end.

As described above, even when a tensile load is applied to the label with slits during use, it is strong against tension in the longitudinal direction, and there is an effect that it does not easily break and become unusable.

On the other hand, in the case of detachment intended to be fraudulent, by forming the oblique slit at an angle with respect to the vertical slit, it is possible to easily break not only the longitudinal direction but also the oblique detachment. . Therefore, there is an effect that it can be reliably broken when peeled off from the adhered object.

In addition, by arranging the inclined slits that are inclined with respect to the vertical slits and away from the vertical slits and the outline, when peeling obliquely from the longitudinal direction or from the four corners, the edges of the inclined slits and the vertical slits or Since the distance to the outline is short, it can be easily broken.
Therefore, there is an effect that it is possible to reliably break the tape when it is peeled off from the sticking object.

On the other hand, by using a removable adhesive in the adhesive layer, the adhesive residue does not occur on the surface of the application target when peeled from the application target, or even if it does occur, it does not adhere in large amounts. .
Therefore, when it is necessary to cleanly peel off the slitted label for gifts, etc., or when the slitted label attached to the eco bag or my basket needs to be peeled off for the next use, There is an effect that the residual piece can be removed from the object to be pasted without leaving any adhesive residue.

A mode for carrying out the present invention will be described below with reference to FIGS. 1 to 4. FIG.
In FIG. 1, the direction L is the horizontal direction, the direction S is the vertical direction, the direction from the front side to the back side of the paper is the front direction, and the direction from the back side to the front side of the paper is the rear direction.

(basic configuration)
The slit label 100 of the present invention has a thin sheet-like base material 1 and an adhesive layer 2 provided on one surface of the base material 1, as shown in FIG. Note that the side view of FIG. 1 emphasizes the thickness of each component for understanding of the layer structure.
The adhesive layer 2 is preferably provided on the entire back surface of the substrate 1, but a non-adhesive portion may be partially provided as necessary.

Also, a release paper having a shape slightly larger than that of the base material 1 may be provided on the surface of the adhesive layer 2 opposite to the base material 1 (not shown).
Although only one slitted label 100 is shown in FIG. 1, a plurality of slitted labels 100 may be arranged side by side on the release paper.

(Configuration of base material)
The base material 1 is a substantially rectangular thin sheet-like member whose longitudinal direction is the horizontal direction L and whose lateral direction is the vertical direction S when viewed from the front.
Paper such as art paper can be suitably used as the material, but if it is a thin sheet that can be attached and peeled off and has physical properties that are easy to break, a thin resin film such as low-density polyethylene can be used. The material is not particularly limited.
The surface of the base material 1 can be subjected to predetermined printing, and can also be subjected to a coating process or the like.

(Structure of adhesive layer)
The adhesive layer 2 is formed with an adhesive that has strength and adhesiveness so that it does not remain on the adhered object when peeled off, and can be formed by coating using a substrate-less acrylic adhesive. . A urethane-based adhesive or a double-faced tape having a substrate may be used as long as it does not remain on the object to be adhered, and can be appropriately selected according to the physical properties of the surface of the object to be adhered.

(Structure of longitudinal slit)
As shown in the front view of FIG. 1, the vertical slit 3 extends in the longitudinal direction along the line connecting the centers of the short sides 12 and 12' of the base material 1, that is, along the center line in the short direction S of the base material 1. , and is a slit that penetrates the substrate 1 and the adhesive layer 2 in the thickness direction.
The length of the longitudinal slit 3 is preferably at least half the length of the long sides 11 and 11' of the substrate 1. The length is preferably at least half the length of the long sides 11 and 11' of the substrate 1.

A gap 32 is provided between the end portion 31 of the longitudinal slit 3 and the short side 12 of the substrate 1 . Similarly, the end portion 31' of the longitudinal slit 3 is provided with a gap 32' between the end portion 31' and the short side 12' of the substrate 1. As shown in FIG.
In this way, the longitudinal slit 3 is formed in a region inside the contour lines 11, 11', 12, 12' of the base material 1, and is located on any of the contour lines 11, 11', 12, 12'. Not connected.

The longitudinal slit 3 divides the width 13 of the central portion of the base material 1 vertically, and the widths 14 and 14' of the divided regions are uniform.

(Structure of inclined slit)
The inclined slits 4a, 4a', 4b, 4b' (4) are the regions between the longitudinal slit 3 and the long sides 11, 11' of the base material 1, that is, the width 14 of the region divided by the longitudinal slit 3.・Nine pieces are formed between 14' and arranged side by side along the vertical slit 3.
The inclined slits 4 are inclined at a predetermined inclination angle 45 with respect to the tangential direction of the longitudinal slits 3, and all the inclined slits 4 are unified at 45 degrees.

In addition, the inclined slit 4 has an end 41 on the longitudinal slit side and an end 42 on the long side. That is, the inclined slit 4 has gaps 43 and 43' between the longitudinal slit 3 and the ends 41 and 41' on the side of the longitudinal slit, and gaps between the long sides 11 and 11' and the ends 42 and 42' on the long side. 44 and 44', and since the inclined slit 4, the vertical slit 3 and the long sides 11 and 11' are separated, they are not connected to any of them.

Regarding the direction of inclination of the inclined slits 4, the ends 42 and 42' on the long side are arranged on the left side, and the ends 41 and 41' on the longitudinal slit side are arranged on the right side. placed in the same direction.

Regarding the arrangement of the end 41 on the longitudinal slit side and the end 42 on the long side, the long sides 11 and 11' are more likely than the gaps 43 and 43' between the longitudinal slit 3 and the ends 41 and 41' on the longitudinal slit side. The gaps 44, 44' with the ends 42, 42' on the long sides are formed to be larger.

In addition, the gaps between the inclined slits 4 are separated by a distance that overlaps with the adjacent inclined slits 4 when the normal lines at the ends 42 and 42' on the long side are extended toward the vertical slit 3, They are unified so that they are all the same.
By separating at such a distance, cracks generated from the ends 41 and 41' on the longitudinal slit side or the ends 42 and 42' on the long side during peeling are easily connected to the adjacent inclined slits 4. The effect of preventing clean peeling becomes more pronounced.

(Deformation and stress during tension)
Next, how the slit label 100 is deformed and what kind of stress acts when the slit label 100 of the present invention is pulled to the left and right to be attached to an object to be attached will be described with reference to FIG. explain.

When pulling the slit label 100 tightly to the left and right, as shown in FIG. It becomes a state in which the load is applied in the direction. The tensile load at this time is a load parallel to the left-right direction, and the same tensile load acts on the load ranges 5 and 5' in opposite directions.

When pulled to the left and right under this condition, the slit label 100 will be stretched to the left and right as shown in FIG. 2(b). It should be noted that FIG. 2(b) shows the state of deformation by enlarging and emphasizing it.
The short sides 12 and 12' have a slightly bulged shape in the load areas 5 and 5', while the long sides 11 and 11' have a bow-shaped constriction at the center.

Here, the vertical slit 3 has overlapping upper and lower ridgelines, one of which is the front side, and the other is the rear side.
In this way, by overlapping the longitudinal slits 3, the central portions of the long sides 11 and 11' can be greatly bent, but the widths 14 and 14' of the divided regions do not change much from before deformation. . That is, the stress generated in the widths 14 and 14' of the divided regions becomes relatively uniform stress along the width direction, as shown in FIG. 2(c). Note that FIG. 2(c) shows the stress distribution with respect to the outline drawing before deformation.

Also, the inclined slit 4 is deformed so as to be opened, but the amount of opening is substantially the same among the inclined slits 4a, 4a', 4b, 4b' (4). As a result, the stress generated at the end 41 on the longitudinal slit side and the end 42 on the long side of each oblique slit 4 in a greatly elongated state is relatively uniform, as shown in FIG. 2(c). stress.

On the other hand, in the case of the slit label 100 without the vertical slit 3, since the dimension in the width direction is wide, even if the same tensile load is applied to the right and left, the slit label 100 does not stretch much. Therefore, since it acts as an impact load immediately after being pulled with a pin, like a static load, before the load is balanced as a whole, the inclined slits 4a and 4a' near the load range 5 and the inclined slit 4i near the load range 5'・The stress is momentarily concentrated on 4i'.
Therefore, if there is no vertical slit 3, the inclined slit 4 will break and become unusable.

(Aspect of breakage during peeling)
Next, a case where the label 100 with slits of the present invention is attached to an object to be attached and then peeled off with the intention of unauthorized use will be described with reference to FIG.
As for the mode of peeling, the direction of peeling in the longitudinal direction from the ridgeline in the lateral direction and the direction of peeling in the oblique direction from the four corners are assumed.

In FIG. 3(a), the direction of peeling from the upper left is indicated by a black arrow, and the direction of peeling from the lower right is indicated by a white arrow. Here, the case of peeling from the lower left is omitted because it is vertically symmetrical with the case of peeling from the upper left. Similarly, the case of peeling from the upper right is omitted because it is vertically symmetrical with the case of peeling from the lower right.
Further, in FIG. 3(b), the direction of peeling from left to right is indicated by a black arrow, and the direction of peeling from right to left is indicated by a white arrow.

First, when peeling from the upper left, the inclined slit 4a arranged substantially parallel to the direction of peeling does not deform in the opening direction of the slit, so the separation boundary line 6 passes through the inclined slit 4a. Even so, stress does not act on the end 41a on the side of the longitudinal slit and the end 42a on the long side, and the peeling is performed cleanly.

However, when the separation boundary line 6 advances and passes through the inclined slit 4a', the inclined slit 4a' is substantially perpendicular to the separation direction (substantially parallel to the separation boundary line 6), so the slit is opened. Such a load acts, and stress in the direction parallel to the peeling direction is generated at the end 41a' on the side of the longitudinal slit and the end 42a' on the long side.
Therefore, from the end 41a' on the side of the vertical slit, a crack is generated toward the adjacent inclined slit 4b', resulting in breakage. Further, a crack is generated from the end 42a' on the long side toward the long side 11', resulting in breakage.

Depending on the peeling angle, when the peeling boundary line 6 passes through the end 31 of the vertical slit 3, a stress in the oblique direction acts on the end 31, and the crack is formed from the end 31 toward the inclined slit 4a'. may occur and break.

On the other hand, in the case of peeling from the lower right, when first passing through the inclined slit 4i', the slit is opened because the inclined slit 4i' is substantially perpendicular to the peeling direction (substantially parallel to the peeling boundary line 6). Such a load acts, and a stress in a direction parallel to the peeling direction is generated at the end 41i' on the side of the longitudinal slit and the end 42i' on the long side.
Therefore, from the end portion 41i' on the side of the vertical slit, a crack is generated toward the vertical slit 3, resulting in breakage. Also, from the end 42i' on the long side, a crack is generated toward the adjacent inclined slit 4h', resulting in breakage.
When the separation boundary line 6 passes through the end 31' of the longitudinal slit 3, a stress in the oblique direction acts on the end 31', so that the end of the inclined slit 4i on the longitudinal slit side from the end 31' It may also crack and break toward 41i.

Next, when peeling from left to right, the short side 12 has a predetermined length. is impossible. Therefore, first, one of the corners is slightly peeled, and then peeled along the short side 12. As shown in FIG. becomes.

First, in the case of peeling from left to right, the vertical slit 3 arranged substantially parallel to the direction of peeling does not deform in the opening direction of the slit. Even if it passes through the edge 31 of , no stress acts on the edge 31 and it is peeled cleanly.

However, when the separation boundary line 6 passes through the inclined slits 4a and 4a', the inclined slits 4a and 4a' are inclined at a predetermined angle, and the separation boundary line 6 is wavy with respect to the short side 12. Since the slits 4a and 4a' are not parallel to each other, stress in the oblique direction acts on the ends 41a and 41a' on the longitudinal slit side and the ends 42a and 42a' on the long side of the oblique slits 4a and 4a'. As a result, cracks are generated from the ends 41a and 41a' on the side of the longitudinal slit toward the longitudinal slit 3, resulting in breakage. Also, cracks are generated from the ends 42 and 42' on the long sides toward the long sides 11 and 11', resulting in breakage.

Here, since the longitudinal slit 3 is not interrupted between the adjacent inclined slits 4a and 4b or between the inclined slits 4a' and 4b' but is continuous, the generated crack is reliably connected to the longitudinal slit 3. , break easily.

The same is true in the case of peeling from right to left. Regarding the longitudinal slits 3 arranged substantially parallel to the peeling direction, since deformation in the opening direction of the slits does not occur, the peeling boundary line 6 does not occur. Even if it passes through the end 31' of the longitudinal slit 3, no stress acts on the end 31' and the film is peeled cleanly.

However, when the separation boundary line 6 passes through the inclined slits 4i and 4i', the inclined slits 4i and 4i' are inclined at a predetermined angle, and the separation boundary line 6 is wavy with respect to the short side 12'. Since the slits 4i and 4i' are not parallel to each other, diagonal stress acts on the ends 41i and 41i' on the longitudinal slit side and the ends 42i and 42i' on the long side of the inclined slits 4i and 4i'. As a result, cracks are generated from the ends 41i and 41i' on the side of the longitudinal slit toward the longitudinal slit 3, resulting in breakage. In addition, cracks are generated from the ends 42i and 42i' on the long sides toward the long sides 11 and 11', resulting in breakage.

As described above, the slitted label 100 of the present invention can be reliably broken regardless of the direction in which the label is to be peeled off in an attempt to be illegally used.
In addition, since a plurality of inclined slits 4 are arranged in parallel, even if one inclined slit 4 is cleanly peeled off, one of the arranged inclined slits 4 will be broken. Therefore, it is very difficult to remove all the inclined slits 4 cleanly.

After peeling the slit label 100 of the present invention, the state shown in FIG. 4 is obtained. When the film is peeled off obliquely, as shown in FIG. 4(a), a mountain-shaped residual piece 7 remains due to the remaining oblique slit 4. As shown in FIG. Moreover, when the film is peeled off in the horizontal direction, an arrow-shaped residual piece 7 remains as shown in FIG. 4(b).
These residual pieces 7, 7, .

As described above, the slit label 100 of the present invention is resistant to tension in the longitudinal direction, so it will not be unusable due to erroneous breakage during use. On the other hand, it is possible to reliably break the tape when it is peeled off from the object to be stuck, and to remove the residual piece after breaking from the object to be stuck without any adhesive residue.

"Modification 1"
Next, modified examples of the label with slits of the present invention will be described with reference to FIGS. 5 and 6. FIG. In addition, the same code|symbol is used about the same part, and the overlapping description is omitted.

(basic configuration)
As shown in FIG. 5, the slit label 101 of this modified example is formed by winding a slit label into a roll.

In addition, the base material 1 has a peelable coating on the surface, and when it is rolled into a roll, there is no need for a release paper between the adhesive layer 2 on the upper side and the base material 1 on the lower side. .
Therefore, when used, the short side 12 on the tip side is pinched with fingers and pulled, so that the wound portions are sequentially peeled off and fed out.

In this modification, the slitted label is continuously connected via the perforation line 8, and the user cuts the label to an arbitrary length using the space between the perforation lines 8 as one unit. be able to.
This perforation line 8 is a perforated line formed by slitting at predetermined intervals, but it may be formed by a method such as providing a V-shaped notch in the long sides 11 and 11' or by half-cutting.

In addition, the inclined slits 4 are inclined so that the ends 42 on the long sides face the tip of the roll, and all the inclined slits 4 are directed in the same direction.

(Deformation and stress during tension)
By the way, in this modified example, when the film is unwound from the roll, the part to be peeled from the roll becomes a linear separation boundary line 6 . In this case, as shown in FIG. 6(a), the tensile load generated when unwinding from the roll is applied to the central portion of the opposing short sides 12 with the entire short sides 12′, which are the separation boundaries 6, fixed. is in the load range 5 and pulled leftward.

When pulled to the left and right under this condition, the slit label 101 will be stretched to the left and right as shown in FIG. 6(b). It should be noted that FIG. 6(b) shows the state of deformation by enlarging and emphasizing it.
In the short side 12, while the portions of the load ranges 5 and 5' are slightly bulged, the short side 12, which is the fixed end, is not deformed. In addition, the long sides 11 and 11' have a bow-like constriction at the center, but the center of the constriction is slightly leftward.

Here, the vertical slit 3 has overlapping upper and lower ridgelines, one of which is the front side, and the other is the rear side.
That is, as in the case of pinching and pulling both ends with fingers, the central portions of the long sides 11 and 11' can be greatly bent by overlapping the longitudinal slits 3, but the widths 14 and 14 of the divided regions ' is not much different from before deformation. That is, the stress generated in the widths 14 and 14' of the divided regions becomes relatively uniform stress along the width direction, as shown in FIG. 6(c). Note that FIG. 6(c) shows the stress distribution with respect to the outline drawing before deformation.

Also, the inclined slits 4 are deformed so as to open evenly. This is because the slanted slit 4 is slanted so that the end 42 on the long side faces the tip of the roll. ' and the distance between the load range 5 and the ends 42a and 42a' on the long side are approximately the same.
That is, the same degree of load acts on the ends 41a and 41a' on the longitudinal slit side and the ends 42a and 42a' on the long side with symmetrical vectors. Therefore, the inclined slits 4a and 4a' are evenly pulled, and the displacement is propagated to the adjacent inclined slits 4b and 4b'.
As a result, the opening amounts of the oblique slits 4a, 4a', 4b, 4b' (4) are substantially the same, so that they are likely to expand greatly. Moreover, the stress generated at the end 41 on the longitudinal slit side and the end 42 on the long side of each inclined slit 4 becomes a relatively uniform stress, as shown in FIG. 6(c).

Therefore, even if the adhesive is pulled vigorously when it is unwound from the roll, the adhesive is slowly peeled off due to elongation. The stress generated at the ends is also reduced.

In addition, when the part that has been paid out is cut to a predetermined length, the tensile load is evenly transmitted along the divided area in the pulled state, and the peeling boundary line 6 from the roll body, which is the fixed end, is bent toward both ends. force is generated. Therefore, by slightly twisting or obliquely displacing the part that is let out in a lightly pulled state, the cutting line 8 is easily cracked, and the inclined slit 4 can be cut off without being broken.

"Modification 2"
Next, another modification of the slitted label of the present invention will be described with reference to FIG. In addition, the same code|symbol is used about the same part, and the overlapping description is omitted.

As shown in FIG. 7, the label with slits 102 of this modified example is a label with slits wound into a roll, and the long sides 11 and 11' are not straight but serrated.
Since the sawtooth shape allows the label to be cut at any position without providing a separate cutting line, the size of the slit label to be attached can be finely adjusted according to the size of the product. can be done.

"Modification 3"
Next, another modified example of the label with slits of the present invention will be described with reference to FIG. In addition, the same code|symbol is used about the same part, and the overlapping description is omitted.

As shown in FIG. 8, the label with slits 103 of this modified example is a flat label with slits, and the short sides 12 and 12' are not straight, but are constricted like a bow.
By forming such a constricted shape, it is possible to guide the peeling so that the peeling always starts from the corner portion, and the breakage can be more reliably performed at the position of the inclined slit 4 .

Further, in this modified example, two longitudinal slits 3 are provided continuously, and a predetermined gap 33 is provided between the longitudinal slits 3.3.
As a result, the strength of the central portion can be improved while maintaining the effect that the whole slitted label 103 is stretched well, so that it is possible to prevent accidental breakage during use.

"Modification 4"
Next, another modified example of the label with slits of the present invention will be described with reference to FIG. In addition, the same code|symbol is used about the same part, and the overlapping description is omitted.

As shown in FIG. 9, the label with slits 104 of this modified example is a flat label with slits, in which the inclination directions of the inclined slits 4 are arranged alternately.
By alternately arranging them alternately in this way, the shape becomes symmetrical in both the vertical direction and the horizontal direction, so that the strength against tension and the easiness of breakage depending on the peeling direction are uniform.

"Variation 5"
Next, another modified example of the label with slits of the present invention will be described with reference to FIG. In addition, the same code|symbol is used about the same part, and the overlapping description is omitted.

As shown in FIG. 10, in the slit label 105 of this modified example, the longitudinal slit 3 is arranged at a position shifted downward from the line connecting the centers of the short sides 12 and 12' of the substrate 1. .

In addition, the inclined slits 4a, 4b, . Also, some of the inclined slits 4d and 4e are arranged so as to partially intersect with each other.
By randomly arranging the slanted slits 4 in this way, the film can be broken by any one of the slanted slits regardless of which direction the film is peeled off.

The slitted label of the present invention is not limited to the above-described form, and for example, the vertical slit 3 can be formed obliquely in the longitudinal direction. Also, two longitudinal slits 3.3 can be provided in parallel.
As another example, a part of the longitudinal slit 3 may be curved or bent, or may have a zigzag shape, or the longitudinal slit may be intermittently provided in a perforated manner.

As for the inclined slit 4, for example, as long as it is inclined as a whole, it may be curved rather than linear, and may be partially perforated.
Also, the inclined slit 4 may be formed in only one of the regions divided by the longitudinal slits 3 .
