Description

  The present invention relates to a pseudo-adhesive label applied to a delivery slip used for transportation and management of articles, a record slip used for application for various insurances and tickets, and the like.

  For example, a delivery slip or the like is used in order to manage a distribution process including ordering of goods, shipping, receipt of a customer, etc. in mail, parcel delivery, mail order sales, and the like. As one of widely used delivery slips, there is a slip in which a plurality of pressure sensitive papers are overlapped. In such a delivery slip, when filling in information such as product name and destination, it is necessary to apply a strong pressure to write the information down to the bottom slip, and a ballpoint pen, typewriter, dot printer, etc. are required. It is said. However, writing with a ballpoint pen or a typewriter is a cumbersome manual operation, and causes erroneous delivery due to typographical errors, omissions, or copying errors. In addition, when using a dot printer, there is a drawback that printing takes time. Furthermore, a part of a delivery slip in which a plurality of pressure sensitive papers are stacked may be broken or peeled off during the distribution process.

  In order to solve the above problems, for example, a surface base material, a pseudo-adhesive layer, a pressure-sensitive adhesive layer, and a release sheet are laminated in this order so that the surface base material and the pseudo-adhesive layer can be peeled off. The pseudo-adhesive label that is pseudo-adhered is used for the delivery slip. The pseudo-adhesive label is used as a delivery slip after the release sheet is peeled off, and an adhesive layer is affixed to the delivery (see, for example, Patent Document 1).

  In the delivery slip of such a pseudo-adhesive label, a cut line is put on the surface of the surface base material on which various printings are applied, and one surface base material can be separated and separated as two label portions. It has become. For example, one label portion is used as a delivery slip, the other label portion is used as a receipt slip, peeled off after stamping / signing, and taken home, and used for slip arrangement.

  By using pseudo-adhesive labels, it is possible to manage the distribution process with a single sheet from the order of goods to the receipt of customers in mail, courier, mail order, etc. Furthermore, slips and loss of slips in the distribution process, etc. Can also be prevented. In addition, since information can be written by laser printer, thermal transfer, etc., it is possible to fill in quickly and to reduce typographical errors and omissions.

Japanese Patent Publication No.55-15035

  However, when the cut line is perforated in the pseudo-adhesive label, the cut is intermittent, and therefore, when the label portion is peeled off, the surface base material may be broken at an unintended portion in the middle of the cut line.

  Therefore, the present invention provides a pseudo-pseudo material that can be peeled off from the pseudo-adhesive layer without tearing the surface base material at a place other than the cut line when the surface base material is separated and peeled at the perforation line. An object is to provide an adhesive label.

  The pseudo-adhesive label according to the present invention has a laminated structure in which a surface base material, a pseudo-adhesive layer pseudo-adhered to the surface base material, and an adhesive layer are laminated in this order, and the adhesive layer is attached to an adherend. A pseudo-adhesive label capable of peeling a surface base material from a pseudo-adhesive layer in a worn state, wherein the surface base material is separated into at least two or more label portions so as to be peelable from the pseudo-adhesive layer It is characterized by comprising a grid-like cutting line, and the midway part in the cutting line has a shape inclined with respect to the linear parts on both sides thereof.

  The midway part is preferably connected to the linear parts on both sides thereof at an obtuse angle. Further, the midway part may be an inclined straight line. Furthermore, the linear portions on both sides may be linear parallel to each other.

  In the present invention, when the surface base material is separated by a perforated cut line and peeled off, the pseudo adhesive label can be peeled off from the pseudo adhesive layer without tearing the surface base material at a place other than the cut line. Can be provided.

It is sectional drawing which shows typically the pseudo | simulation adhesive label which concerns on embodiment of this invention. It is a top view which shows typically the pseudo adhesive label which concerns on embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view schematically showing a pseudo-adhesive label according to an embodiment of the present invention, and FIG. 2 is a plan view thereof.

  As shown in FIG. 1, a pseudo-adhesive label 10 according to an embodiment of the present invention includes a surface base material 11, a pseudo-adhesion layer 12 that is pseudo-adhered to the surface base material 11, and an adhesive layer that is adhered to the pseudo-adhesion layer 12. 13 has a laminated structure in which the layers are laminated in this order, and a peeling substrate 14 is attached to the pressure-sensitive adhesive layer 13. The pseudo-adhesive label 10 is used after the release substrate 14 is peeled off from the pressure-sensitive adhesive layer 13 and is adhered to an adherend (not shown) by the exposed pressure-sensitive adhesive layer 13.

  The pseudo-adhesion layer 12 is pseudo-adhered to the surface base material 11 so as to be peeled off, and the surface base material 11 is peeled from the pseudo-adhesion layer 12 in a state where the pseudo-adhesive label 10 is attached to the adherend. In the pseudo-adhesive label 10, a large number of cuts 20x are cut from the surface of the surface base material 11, and the cut line 20x forms a perforated cutting line 20 (see FIG. 2). As shown in FIG. 1, the cut 20 x is cut from the surface of the surface base material 11 and penetrates the surface base material 11, the pseudo adhesive layer 12, and the pressure-sensitive adhesive layer 13. Note that the pseudo adhesive layer 12 and the pressure-sensitive adhesive layer 13 do not have to be cut as long as the cut 20x penetrates to the back surface of the surface base material 11. However, when the surface base material 11 is provided with a thermoplastic resin layer or a release agent layer, which will be described later, on the back surface thereof, they are also cut.

  As the surface base material 11, for example, high-quality paper, thermal transfer paper, craft paper, glassine paper, thermal paper, synthetic paper, or plastic film is used. The thickness of the surface base material 11 is 15-120 micrometers, for example, Preferably it is 20-110 micrometers, More preferably, it is 30-100 micrometers. The surface of the surface substrate 11 is used as a surface for displaying information such as characters.

  The pseudo adhesive layer 12 is not particularly limited as long as it is pseudo-adhered to the surface substrate 11 so as to be peeled off, but is preferably a thermoplastic resin layer. The thermoplastic resin layer is formed, for example, by extrusion laminating a heat-melted thermoplastic resin on the back surface of the surface base material 11. As the thermoplastic resin for forming the thermoplastic resin layer, for example, polyethylene, polypropylene, polymethylpentene and the like are used alone or in admixture of two or more. Although the thickness of a thermoplastic resin layer is not specifically limited, For example, it is 3-70 micrometers, Preferably it is 5-50 micrometers.

  A release agent layer may be coated on the back surface of the surface base material 11 so that the surface base material 11 can be easily peeled off from the pseudo adhesive layer 12. The release agent layer is not particularly limited, but styrene-acrylic copolymer, polystyrene, styrene-butadiene copolymer, ethylene vinyl acetate copolymer, acrylic acid ester, acrylic acid ester copolymer, ethylene / acrylic acid copolymer. It is formed by a mold release agent made of a polymer or the like. In addition, the surface base material 11 peels in the interface of the pseudo adhesion layer 12 and a mold release agent layer, when a mold release agent layer is provided. Moreover, the surface base material 11 may be further provided with a thermoplastic resin layer formed of the thermoplastic resin and a release agent layer in this order on the back surface.

  The pressure-sensitive adhesive layer 13 is provided on the back side of the pseudo-adhesive layer 12 and is a layer for adhering the pseudo-adhesive label 10 to an adherend, and is an acrylic pressure-sensitive adhesive, natural rubber-based pressure-sensitive adhesive, and synthetic rubber-based pressure-sensitive adhesive. It is formed from a conventionally known adhesive such as a silicone-based adhesive. Although the thickness of the adhesive layer 13 is not specifically limited, For example, 5-50 micrometers, Preferably it is 10-40 micrometers. The release substrate 14 is a release sheet or the like whose surface to be attached to the pressure-sensitive adhesive layer 13 is subjected to a release treatment with a silicone release agent or the like.

  The pressure-sensitive adhesive layer 13 is formed, for example, by applying a pressure-sensitive adhesive to the peeling substrate 14. And the pseudoadhesion label 10 is obtained by bonding the pseudoadhesion layer 12 laminated | stacked on the surface base material 11 to the adhesive layer 13 formed on the peeling base material 14 together. However, the pressure-sensitive adhesive layer 13 is formed by directly coating the pseudo-adhesive layer 12 laminated on the surface base material 11, and the pseudo-adhesive label 10 is formed by pasting the release base material 14 thereon. Also good.

  As shown in FIG. 2, the pseudo-adhesive label 10 according to the embodiment of the present invention is obtained by punching and cutting the surface base material 11, the pseudo-adhesive layer 12, and the pressure-sensitive adhesive layer 13 by performing a punching process. Unnecessary portions are removed from the peeling base material 14 by raising the residue, and a substantially rectangular label having the lower side 10A and the upper side 10B as long sides and the left and right side sides 10C and 10D as short sides is formed. The pseudo-adhesive label 10 is perforated at a substantially central portion together with the punching process, and a cutting line 20 is formed at a substantially central portion of the surface base material 11. The punching and perforation are performed using, for example, a die cutter, but may be performed by laser irradiation or the like.

  As shown in FIG. 2, the cutting line 20 extends from the lower side 10 </ b> A to the upper side 10 </ b> B of the surface base material 11. The surface base material 11 can be separated from the pseudo-adhesive layer 12 by being separated into right and left substantially rectangular sheets (referred to as label portions 18 and 19) by a cutting line 20.

  In the cutting line 20, the midway part 20 b is inclined with respect to the linear parts 20 a and 20 c on both sides thereof, and has a crank-like bent line shape in plan view. The linear portions 20 a and 20 c are straight lines that are parallel to each other and extend in the vertical direction, and extend to the lower side 10 </ b> A and the upper side 10 </ b> B that are the outer edges of the surface base material 11, respectively. The midway portion 20b is a linear inclined portion connected to the upper and lower ends of the linear portions 20a and 20c at an obtuse angle (preferably 95 ° to 165 °, more preferably 100 ° to 145 °). The midway portion 20 b is disposed at a substantially central position of the cutting line 20.

  As described above, the cutting line 20 has a bent line shape in which the upper linear portion 20c is shifted laterally with respect to the lower linear portion 20a via the midway portion 20b. The width X of the entire cutting line 20 is the distance between the two linear portions 20a and 20c in the lateral direction (that is, the bending width). The width X is preferably 2 mm to 20 mm, and more preferably 3 mm to 10 mm. If the width X is too large, it is not preferable in terms of the shape of the label, and if it is too small, the surface substrate 11 is easily broken.

  Further, since the cutting line 20 has a bent line shape as described above, the lower part of the label portion 18 has a shape protruding to the label portion 19 side, and peeling starts on the protruding portion as described later. There is a corner 18A to be a part. Similarly, the upper portion of the label portion 19 has a shape protruding to the label portion 18 side, and has a corner portion 19B that becomes a peeling start portion.

  The plurality of cuts 20x constituting the cutting line 20 are continuously provided with a distance d from the lower side 10A to the upper side 10B. The cuts 20x and 20x arranged at the lowermost end and the uppermost end of the cutting line 20 are connected to the lower side 10A and the upper side 10B.

  The length of the cut 20x is preferably longer than the distance d between the cuts 20x and 20x. When the length of the cut 20x is shorter than the separation distance d, the surface base material 11 is not easily separated along the cutting line 20, and tearing is likely to occur. The length of the cut 20x is, for example, 0.2 to 15 mm, preferably 0.4 to 10 mm, and the separation distance d of each cut 20x is, for example, 0.1 to 1 mm, preferably 0.2 to 0.8 mm. It is. When the length and the separation distance of the cut 20x are out of the above ranges, the surface base material 11 is difficult to be separated along the cutting line 20 when the label portions 18 and 19 are peeled off, and breakage is likely to occur.

  Next, the peeling method of the surface base material 11 in the pseudo adhesive label 10 is demonstrated. For example, the label portion 18 of the surface base material 11 is separated by, for example, picking the corner portion 18A of the label portion 18 at the position where the lower side 10A intersects the cutting line 20 as a peeling start portion and placing the surface base material 11 in the peeling direction A. This is done by peeling off. At this time, the label portion 18 is peeled from the pseudo adhesive layer 12 while cutting the surface base material 11 along the cutting line 20 so as to leave the label portion 19 side.

  In the present embodiment, when the label portion 18 is peeled from the corner portion 18A, the peeling direction A is inclined in the same direction as the midway portion 20b with respect to the vertical direction. Therefore, when the label portion 18 is peeled off in the peeling direction A, the force applied to the surface base material 11 is easily transmitted along the cutting line 20, and thereby the surface is moved from an unintended position in the middle of the cutting line 20. It is prevented that the base material 11 is torn. Moreover, since the cutting line 20 inclines near the center of the cutting line 20 in which unintended tearing is likely to occur, the surface base material 11 is more effectively prevented from being torn.

  Further, since the label portions 18 and 19 are easily cut along the cutting line 20, even if the cutting line 20 is formed perpendicular to the flow direction or the film stretching direction, the surface substrate 11 is torn. It becomes difficult. Furthermore, since the lowermost cut 20x in the cutting line 20 is connected to the lower side 10A, peeling of the label portion 18 can easily start from the corner portion 18A.

  In the above description, of the two label portions, the operation when the label portion 18 is peeled first has been described. However, the label portion 19 is located at a position where the upper side 10B and the cutting line 20 intersect. When 19B is used as the peeling start portion, tearing of the label portion 19 is prevented by the same action when peeling off first. Further, after the one label portion is peeled off, the remaining label portion is appropriately peeled off from the pseudo peeling layer 12.

  In the present embodiment, as described above, unless the midway portion 20b is inclined in the same direction as the peeling direction A, it is difficult to peel off the label portion 18 without causing tearing. That is, in the said embodiment, it is difficult to peel off the label part 18 by making the corner | angular part 18B of the label part 18 in the position where the upper side 10B and the cutting line 20 cross | intersect into a peeling start part. Therefore, a mark or the like may be attached to the surface base material 11 or the like, for example, indicating that the corner portion 18A is a peeling start portion of the label portion 18. An arrow indicating the peeling direction A may be attached on the surface base material 11. Similarly, it may be indicated that the corner portion 19B is a peeling start portion. However, in this embodiment, even if a mark or the like is not added, the corners 18A and 19B are located on the protruding portions of the label portions 18 and 19, respectively, so that it is easy for the user to recognize the peeling start portion.

  In some cases, the pseudo-adhesive label 10 has a predetermined one of the two label portions to be peeled first. For example, when a pseudo-adhesive label is used for a delivery slip, the label portion 18 is a receipt slip and the label portion 19 is a delivery slip, the label portion 18 is peeled first. In such a case, in order to make it easy to peel off the label portion 18 from the corner portion 18A, the cut 20x at the lowermost end of the cutting line 20 needs to be connected to the lower side 10A, but the cut at the uppermost end is connected to the upper side 10B. There is no need to connect.

  Moreover, although the midway part 20b was formed in the straight line, it is not limited to a straight line, The curve may be included. Further, the midway portion 20b may be provided with a plurality of inclined portions and have a stepped shape. Similarly, the linear portions 20a and 20c may include curves. Furthermore, another linear part may be connected to the linear parts 20a and 20c, and the linear part may be connected to the lower sides 10A and 10B.

  Moreover, the space | interval between each cut | interruption 20x of the cutting line 20 may be half-cut so that it may not penetrate completely to the back surface of the surface base material 11, or a streak-like hollow may be formed by muscle pushing.

  In the above-described embodiment, the label portions 18 and 19 are substantially rectangular. However, the shape is not limited to a rectangle, and may be another polygon such as a triangle or a circle. Further, the structure and material of the pseudo-adhesive label 10 are not limited to the above embodiment. For example, you may provide layers other than the surface base material 11, the pseudo adhesion layer 12, and the adhesive layer 13. Further, the intervals between the cutting lines and the lengths of the cut lines may be uniform or non-uniform. Furthermore, the structure and material of the pseudo-adhesive label 10 are not limited to the above embodiment. For example, you may provide layers other than the surface base material 11, the pseudo adhesion layer 12, and the adhesive layer 13.

  Next, the present invention will be described below using examples, but the present invention is not limited to the configurations of the following examples.

[Example 1]
Tack base paper (manufactured by YUPO Corporation, trade name: YUPO TACK base paper 60SGS) was used as the surface substrate. Polypropylene (manufactured by Sun Allomer, trade name: Sun Allomer PHA03A) was used as the thermoplastic resin for forming the pseudo adhesive layer. The thermoplastic resin was extruded with a T-die so that the extrusion temperature was 290 ° C. and the thickness was 20 μm, and a thermoplastic resin was laminated on the back surface of the tack base paper to obtain a pseudo-adhesive sheet. Next, an acrylic pressure-sensitive adhesive is applied to the release agent surface of the silicone release paper to a thickness of 25 μm to form a pressure-sensitive adhesive layer, which is then bonded to the pseudo-adhesive layer of the previously formed pseudo-adhesive sheet. It was. Thereafter, punching, perforation, and scrap removal were performed to obtain a pseudo-adhesive label as shown in FIG.

  The pseudo-adhesive label was 150 mm wide and 100 mm long, and a cut line was provided at the center in the horizontal direction. The lengths of the cuts 20x constituting the cutting line 20 were each 1 mm, and the separation distance d between the cuts was 0.3 mm. The length of the linear portions 20a and 20c was 46 mm, the length of the midway portion 20b was 10 mm, and the midway portion 20b was connected to the linear portions 20a and 20c at 120 degrees. Further, the width X of the cutting line was 5 mm. In addition, the cut was made into the depth which penetrates a surface base material, a pseudo adhesion layer, and an adhesion layer.

[Comparative Example 1]
The cutting line was carried out in the same manner as in Example 1 except that the cutting line was formed so as to extend linearly in the longitudinal direction in the approximate center of the pseudo-adhesive label.

[Evaluation method: Pseudo-side peeling test]
The peeling base material of the pseudo-adhesive label obtained in Examples and Comparative Examples was peeled off and removed, and an adhesive layer was stuck on a mount as an adherend. In this state, can the test be performed 10 times to peel the label portion 18 of the surface base material 11 from the corner 18A shown in FIG. 2 in the direction of arrow A at a peeling angle of 180 °, and the surface base material can be peeled without breaking? Evaluated. The number of occurrences of tearing of the surface base material was expressed as a peel failure rate (number of breaks generated / number of tests × 100).

Table 1 shows the results of the evaluation test of the pseudo-adhesive labels obtained in the examples and comparative examples.

  In Comparative Example 1 in which the cutting line was linear, it was difficult to cut the surface base material along the cutting line, and the surface base material was easily broken when the label part was peeled off. It was.

  On the other hand, in Example 1, since it was possible to peel from the pseudo-adhesive layer without tearing the surface base material at the time of peeling, the peel failure rate was good at less than 20%. Thus, by forming the cutting line into a bent line shape in plan view, when the surface base material is separated by the cutting line and peeled off, the surface base material is peeled off from the pseudo-adhesive layer without being broken. Thus, a pseudo-adhesive label with good workability was obtained.
