Description

  The present invention relates to a label having a perforation structure for breaking in a prescribed breaking direction.

  2. Description of the Related Art A perforation structure is widely known as a structure for breaking a packaging material or label made of a sheet material, a film, or the like along a line assumed in advance. As is well known, the perforation structure is a structure in which cut lines are intermittently arranged along an assumed line. However, in the case of a perforation in which only straight cut lines are arranged, in the process of transitioning from one cut line to an adjacent cut line, the direction of breakage may be greatly deviated depending on the direction in which the force is applied. Breakage may proceed without reaching the score line. In this case, the break along the line assumed here cannot be continued.

  Patent Documents 1 and 2 disclose techniques for avoiding such a problem. Specifically, in Patent Documents 1 and 2, two rows of cut lines having a two-dimensional expansion such as a substantially C-shape or V-shape are arranged so that the inside faces each other across an assumed line. In addition, a configuration is disclosed in which the cut lines are arranged in an intermittent manner so that the cut lines end inward in the spread width of the opposed cut lines. Patent Document 2 also discloses a technique for forming a cut line having an approximately Y-shape that expands in a bifurcated shape toward one direction of an assumed line in an intermittent manner. According to such a perforation structure, the cut end on one end side terminates inward of the spread width of the other cut line, so that the possibility that the deviation in the breaking direction can be corrected by the next cut line is increased.

  However, in the case of a Y-shaped cut line, there is no problem if it breaks from the side where the cut line extends in a bifurcated shape. There is a problem that the line of sight cannot be corrected and the break along the assumed line cannot be made.

  In the case of a structure in which C-shaped or V-shaped cut lines are arranged in two rows, the same effect can be obtained regardless of the direction of fracture. However, the C-shaped and V-shaped score lines have a small width in the breaking direction. Therefore, in such a structure, it is necessary to arrange a large number of score lines as compared with the distance to be broken. If the number of cut lines is large, the number of joints that are connecting portions located between the cut line and the next cut line increases accordingly. Since the deviation of breakage occurs at this joint, in the case of the C-shaped and V-shaped perforation structures having a large number of joints, there is a high possibility that the breakage will occur.

  Therefore, an object of the present invention is to provide a label having a perforation structure that can achieve a desired break more reliably regardless of the direction of break progress.

  The label of the present invention is a label having a perforation structure for breaking along a predetermined break line, and the perforation structure has a plurality of cut lines arranged intermittently along the break line. Each score line has a main score line extending in the direction of the break line, and at least two branch score lines that extend from both ends of the main score line and face each other across the break line, The branched cut lines facing each other across the break line are shaped to advance from the end of the main cut line in a direction away from each other and then toward each other. It has a shape that intersects with the next branch cut line located on the opposite side across the line.

In a preferred embodiment, the plurality of score line, said the end of the breaking direction of the label, the main score line is arranged so as to be located. In another preferred embodiment, the label is a seal label that is affixed to a product and partially cut and peeled off. In another suitable aspect, the sticking force of the part cut | disconnected and peeled among the said labels is smaller than the sticking force of the part which remain | survives in a product.

  In another preferred aspect, an angle formed by the main cut line and the branch cut line, a bending angle of a portion where the branch cut line changes direction, an intersection of the extension line of the branch cut line and the next branch cut line At least one of the angles is 90 degrees or more. In another preferred aspect, at least a part of the score line is configured by a curve.

  According to the present invention, the both ends of the main score line face each other across the fracture line, and after proceeding in a direction away from each other from the end of the main score line, the extension line extending from the end is advanced in the direction approaching each other. A branch cut line that intersects with the next branch cut line located on the opposite side across the break line is provided. Therefore, regardless of the direction of break progress, the allowable angle range of deviation in the break progress direction can be increased, and the course out where the break does not deviate greatly from the break line and return can be prevented more reliably.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view showing a state in which a seal label 10 according to an embodiment of the present invention is attached to a product 100. The seal label 10 is affixed to various products 100 for the purpose of identifying the product 100, improving the design, and presenting the opened state (notifying the user whether or not the product 100 has been opened). In addition, in FIG. 1, although the state stuck on the substantially cylindrical product 100 is shown, the shape, kind, etc. of the product 100 to which the seal label 10 is stuck are not particularly limited.

  A part of the seal label 10 of the present embodiment can be cut and peeled off. For this cutting, the seal label 10 is provided with a perforation 12 extending along a predetermined breaking line (left and right direction in FIG. 1) and crossing the entire width of the seal label 10. The seal label 10 is divided into a peeling portion 14 to be cut and peeled and a remaining portion 16 remaining in the product 100 with the perforation 12 as a boundary. In the illustrated example of FIG. 1, the upper half of the seal label 10 is the remaining portion 16, and the lower half is the peeling portion 14. A knob portion 18 that is not bonded is provided at one corner of the peeling portion 14. When peeling the peeling part 14, the user peels the peeling part 14 from the product 100 by picking and pulling the knob part 18 with a finger. Note that the number, position, and shape of the knob portions 18 may be appropriately changed. For example, the knob portion 18 is not necessarily provided. Further, in consideration of workability when the seal label 10 is peeled off, a knob portion that is not bonded may be provided at both the left and right corner portions.

  Moreover, in this embodiment, in order to make the peeling part 14 easier to peel, the sticking force of the peeling part 14 is made smaller than the sticking force of the remaining part 16. Examples of a method for reducing the sticking force of the peeling portion 14 include a paste killing process. Further, depending on the material of the seal label 10 and the type of adhesive, it is not always necessary to make the sticking force of the peeling portion 14 weaker than the sticking force of the remaining portion 16. Good.

  Although there are various purposes for cutting off and peeling off a part of the seal label 10, in this embodiment, the peeling portion 14 is provided in order to store the identification information of the product 100. That is, in this embodiment, a medical device is assumed as the product 100 to which the seal label 10 is attached. In the medical device, there is a demand for recording and storing the identification information of the used product 100 in association with the patient's medical record. In order to meet this requirement, in the present embodiment, the identification information of the product 100 is described in the peeling part 14, and when the product 100 is used, the peeling part 14 is cut off and peeled off and pasted on the patient's chart. I am trying to attach it. Needless to say, the purpose of peeling described here is merely an example, and the technology of the present embodiment may be applied to a product in which a part of the seal label 10 is cut for other purposes. For example, the technology of the present embodiment may be applied to a product in which a part of the seal label is cut off and peeled off in order to view product opening, prize information or the like that is covered with the seal label 10 and hidden.

  Here, as a technique for tearing a sheet-like member such as the seal label 10, a perforation in which a score line is intermittently arranged along a fracture line assumed in advance is widely known. However, in the case of a simple perforation in which straight cut lines are arranged side by side, the direction of breakage is greatly deviated depending on the direction in which the force is applied in the process of transition from one cut line to the adjacent cut line. The rupture may proceed without reaching the adjacent score line. In this case, it was not possible to break along the break line assumed in advance, and it was not possible to cut and open as desired. Therefore, in the present embodiment, the perforation 12 has a special configuration so that a desired fracture can be achieved more reliably. Hereinafter, the configuration of the perforation 12 will be described in detail.

  FIG. 2 is a partially enlarged view of the perforation 12 of the present embodiment. 3 and 4 are enlarged views around the branch cut line. For ease of viewing, the broken line is not shown in FIGS. As shown in FIG. 2, the perforation 12 of the present embodiment includes a plurality of cut lines 20 that are intermittently arranged along the fracture line Lc assumed in advance. Hereinafter, a portion where the cut line 20 located between the cut line 20 and the cut line 20 is not provided is referred to as a “joint portion 30”.

  Each cut line 20 has a shape in which two branch cut lines 24 extending in a bifurcated manner extend from both ends of the main cut line 22 extending on the fracture line Lc. When arranging a plurality of cut lines 20, as shown in FIG. 1, the main cut lines 22, i.e., the straight cut line portions, intersect with the end portions of the seal label 10. The size and position of the part 30 are adjusted.

  A pair of branch cut lines 24 extending from one end portion of the main cut line 22 are symmetrical with respect to the break line Lc, and face each other with the break line Lc interposed therebetween. The pair of branch cut lines 24 travel in directions away from the ends of the main score line 22 and then in directions toward each other. In other words, the pair of branch cut lines 24 has a shape that converges after being expanded two-dimensionally from the end of the main cut line 22. More specifically, in the present embodiment, the pair of branch cut lines 24 form an incomplete rhombus in which the vicinity of one apex of the rhombus is missing. Further, as shown in FIG. 3, each branch cut line 24 is arranged so that the extension line Le from the end Pe intersects the next branch cut line 24 located on the opposite side across the fracture line Lc. The angle and length of the branch cut line 24 are adjusted.

  The reason why each cut line 20 is configured as described above will be described. In the following description, the case where the fracture occurs mainly from the lower branch cut line 24 will be described as an example. However, the same applies to the case where the fracture occurs from the upper branch cut line 24, and the description thereof will be omitted. In the present embodiment, one of the purposes is to prevent a course-out in which the progressing direction of the break is largely deviated from the break line Lc and cannot be returned. One of the causes of such a course-out is that the number of joints 30 is large. That is, at each score line 20, the seal label 10 has already been broken (cut), and the breakage of the seal label 10 actually proceeds at the joint 30. The greater the number of joints 30, the higher the possibility that the direction of breakage will deviate and, in turn, cause a course out. Therefore, in the present embodiment, each main cut line 20 is provided with a linear main cut line 22 extending in the direction of the breaking line Lc, and the entire cut line 20 is lengthened. As a result, the number of necessary score lines 20 and thus the number of joint portions 30 can be greatly reduced, and the breakout course can be effectively prevented.

  Another cause of the break-out course is that the angular range in which breakage is allowed is narrow. That is, in the case of the conventional general perforation in which the straight cut lines 20 are arranged in the same straight line, the break proceeding from the end of one cut line is the following unless the straight line extends on the extension line of the cut line. Unable to reach the score line. Therefore, in the case of a conventional general perforation, the allowable angle range of the breaking deviation is almost zero.

  On the other hand, in the present embodiment, as described above, the extension line Le extending from the end Pe of one branch cut line 24 intersects the next branch cut line 24 located on the opposite side across the fracture line Lc. Therefore, even if the progress direction of the break proceeding from the end Pe of one branch cut line 24 is slightly deviated from the extension line Le, the next branch cut line 24 can be reached.

  Further, in the present embodiment, two branching cut lines 24 that face each other across the break line Lc are provided at the end of each cut line 20. In other words, branch cut lines 24 are arranged on both sides of the break line Lc. Therefore, not only when the rupture proceeds in a direction crossing the rupture line Lc (such as the b direction in FIG. 3), but also when the rupture proceeds in a direction not intersecting the rupture line Lc (such as the a direction in FIG. 3). It is easy to make the break reach the next score line 20. This will be described with reference to FIGS. FIG. 5 is a diagram for comparison with the present embodiment, and is a diagram in the case where there is only one branching cut line 24 extending from the end of each main cut line 22. Even in the configuration of FIG. 5, the extension line Le of the end Pe of one branch cut line 24 intersects the next branch cut line 24 located on the opposite side across the break line Lc. To some extent acceptable. However, in the configuration of FIG. 5, the allowable angle range is only a deviation in the direction crossing the fracture line Lc. When the rupture deviates in a direction that does not cross the rupture line Lc, for example, in the direction a in FIG. 3, a course-out in which the rupture greatly deviates from the perforation 12 occurs.

  On the other hand, in the present embodiment, two branch cut lines 24 facing each other across the break line Lc are provided. Therefore, as shown in FIG. 4, not only the deviation in the direction crossing the fracture line Lc (the direction b in FIG. 3) but also the deviation in the direction not traversing the fracture line Lc (the direction a in FIG. 3). To some extent acceptable. More specifically, in this embodiment, if the angle α is between the straight line A and the straight line B in FIG. The straight line A is a straight line connecting the end of one branch cut line 24 and the end of the next branch cut line 24 located on the opposite side across the break line, and the straight line B is one branch cut line. This is a straight line connecting the end of the line of sight 24 and the vertex of the next branch cut line 24 located on the same side as viewed from the breaking line.

  As described above, in the present embodiment, the extension line Le of the end Pe of one branch cut line 24 intersects with the next branch cut line 24 located on the opposite side across the branch cut line 24 and the fracture line Lc. And since the edge part of each cut line 20 is bifurcated, the allowable range angle of the deviation of the breakage is greatly increased, and as a result, the course out of the breakage can be effectively prevented.

  In addition, the deviation | shift to the direction which does not cross the fracture | rupture line Lc is easy to produce also when the sticking force differs by the perforation 12 like a boundary like the seal label 10 of this embodiment. That is, in this embodiment, the sticking force of the remaining part 16 located above the perforation 12 is stronger than the sticking force of the peeling part 14 located below the perforation 12. In this case, the breakage hardly proceeds to the remaining portion 16 side and easily proceeds to the peeling portion 14 side. Therefore, when there is a difference in the sticking force and strength of the seal label 10 with the perforation 12 as a boundary and the easiness of breakage is different, the configuration for branching the end portion of the cut line 20 into two branches is as follows. Is particularly effective.

  Furthermore, another cause of the break-out course is that the distance at which the break progresses is long at the joint 30. The longer the distance at which the break occurs at the joint 30, the greater the amount of breakage that tends to increase, and a course-out tends to occur. In the present embodiment, as described above, since the end portion of the score line 20 is bifurcated, the distance at which the breakage proceeds at the joint portion 30 can also be shortened. This will also be described with reference to FIGS.

  As shown in FIG. 5, when the end portion of the cut line 20 is not branched, the shortest distance D3 for the break from one cut line 20 to the next cut line 20 is the break from the end of one branch cut line 24. This is a distance D3 to the end of the next branch cut line 24 located on the opposite side across the line Lc.

  On the other hand, when the end of the cut line 20 is branched as in the present embodiment, the shortest break distance from one cut line 20 to the next cut line 20 is from the end of one branch cut line 24. The distance to the end of the next branch cut line 24 located on the same side as viewed from the fracture line Lc, that is, the distance D2 of the joint portion, even if the distance of the joint portion 30 is the same, compared to the configuration of FIG. Can be shortened. As a result, it is possible to shorten the distance at which the rupture proceeds at the joint portion 30, and to effectively prevent the course out of which the direction of the rupture greatly deviates.

  As is clear from the above description, in the present embodiment, each score line 20 has a left-right symmetrical shape. Therefore, the same effect can be obtained when the fracture is advanced from the right side to the left side, or conversely, when the fracture is advanced from the left side to the right side. In other words, according to the present embodiment, even if the breakage is started from either the left or right end portion of the perforation 12, the breakout course is effectively prevented and a good breakage is possible.

  Next, a desirable dimension of the cut line 20 will be briefly described. Desirable dimensions of the cut line 20 vary depending on the size, material, design, etc. of the seal label 10 to which the perforation 12 is applied. For example, in order to reduce the number of joint portions 30, it is desirable that the length D1 of the score line 20, particularly the main score line 22, is longer. However, if the cut line 20 is excessively long, the number of the joint portions 30 is extremely reduced, so that the stiffness of the perforation portion is weakened, the seal label 10 is bent, and sticking to the product 100 becomes difficult. Therefore, it is desirable to determine the length of the score line 20 according to the strength of the seal label 10 or the like. Moreover, in order to prevent the course out of breakage, it is desirable that the distance D2 of the joint portion 30 is short. However, if the distance D2 is excessively short, the stiffness of the perforated portion of the seal label 10 is also weakened. Therefore, it is desirable to determine the length of the score line 20 and the distance of the joint portion 30 according to the characteristics of the seal label 10.

  In order to prevent the course from breaking, it is desirable to increase the allowable angle range α of breaking deviation as much as possible. Therefore, it is desirable to set the shape and size of the branch cut line 24 and the distance D2 of the joint 30 to values that can increase the allowable angle range α. However, since the breakage that proceeds through the joint portion 30 basically proceeds along the extension line Le of the branch cut line 24, it is desirable that the allowable angle range α is symmetric about the extension line Le. That is, it is desirable that the angle β and the angle γ in FIG. However, since the breakage tends to proceed to a weak portion, when the distance D2 of the joint portion 30 is short and the distance from one branch cut line 24 to the next branch cut line 24 is short, the break is in the extension line Le direction. In addition to this, it is easy to proceed in the direction of the straight line C in FIG. Therefore, in this case, the angle range formed by the extension line Le and the straight line C can be said to be the angle range δ where the breakage is likely to proceed. In such a case, it is desirable that the allowable angle range α is symmetric with respect to the angle range formed by the extension line Le and the straight line C. That is, it is desirable that the angle β and the angle ε in FIG.

  Further, since the break proceeds smoothly as the bend in the traveling path is smaller, as shown in FIG. 3, an angle (subordinate angle) θ1 formed by the main cut line 22 and the branch cut line 24, and the branch cut line 24 At least one of the bending angle θ2 and the intersection angle θ3 between the extension line Le of the branch cut line 24 and the next branch cut line 24 is desirably 90 degrees or more, and more desirably, all are 90 degrees or more.

  The configurations described so far are all examples, and at the end of each cut line 20, there are at least two branch cut lines 24 facing each other across the fracture line Lc, and the end of each branch cut line 24. As long as the extended line Le from Pe intersects with the next branch cut line 24 located on the opposite side across the fracture line Lc, other configurations may be appropriately changed.

  For example, in the present embodiment, the branch cut line 24 is configured only by a straight line. However, as shown in FIGS. 6 and 7, a part of the branch cut line 24, for example, around the connection part between the main cut line 22 and the branch cut line 24, You may comprise the direction change part in the branch cut line 24 with a curve. Further, the main score line 22 is not necessarily a straight line as long as it extends in the direction of the breaking line Lc as a whole. For example, as shown in FIG. In the present embodiment, both ends of the main cut line 22 are bifurcated. However, two branch cut lines that face each other across the fracture line Lc and whose extension line intersects the next branch cut line 24 are arranged. If there are 24, the number of branches may be larger. Therefore, for example, the two branch cut lines 24 facing each other across the cutting line and the branch cut line 24 extending on the fracture line may be branched into three. Further, it may be branched into four so as to have four branch cut lines 24 facing each other.

  In the description so far, the seal label 10 that is attached to the product 100 and partially cut and peeled has been described as an example. However, the perforation 12 of the present embodiment may be applied to other labels. . For example, the label to be perforated is not limited to a seal label, and may be a label that does not have a sealing performance and is not attached to a product. The perforation may be provided for purposes other than label cutting. Therefore, the perforation may extend only to a part of the label instead of crossing the entire width of the label.
