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 recent years, 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, and the surface base material and the pseudo adhesive layer can be peeled off. The pseudo-adhesive label thus pseudo-adhered is being used for delivery slips (see, for example, Patent Documents 1 and 2). The pseudo-adhesive label is used as a delivery slip after the release sheet is peeled off and the adhesive layer is attached to the delivery. Such a delivery slip for a pseudo-adhesive label is usually provided with a half-cut line so that one surface substrate can be separated and separated as two label portions. 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.

  However, pseudo-adhesive labels, especially pseudo-adhesive labels used for delivery slips and record slips, are usually made of a fragile and thin material such as paper. When doing so, there is a drawback that the surface substrate is easily broken.

In the pseudo-adhesive label described in Patent Document 2, a water-dispersible release agent is applied to the interface between the surface base material and the pseudo-adhesive layer, where the cut line is entered, and the base material is made of a thermoplastic resin layer. The structure which makes it easy to peel from is disclosed. However, even with this configuration, the surface base material cannot be sufficiently prevented from being broken.
Japanese Patent Laid-Open No. 11-202771 JP-A-11-256112

  Therefore, the present invention has been made in view of the above problems, and even if the surface substrate is a fragile and thin material such as paper, the surface substrate is peeled off from the pseudo-adhesive layer so as not to break. It is an object to provide a pseudo-adhesive label that can be used.

  In the pseudo-adhesive label according to the present invention, 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, In the pseudo-adhesive label that peels between the adhesive layer and the pseudo-adhesive layer, the entire surface base material is peeled off from the pseudo-adhesive layer as a label part, or part of the surface base material is separated and separated from the other part as a label part. At least a part of the peripheral part of the part is a non-adhesive part that is not adhered to the adherend by the adhesive layer, and a part other than the non-adhesive part is used as a peeling start part.

  It is preferable that the corner portion of the label portion is used as the peeling start portion. More preferably, the surface base material is separated into two or more label portions by a cut line and can be peeled off, and a corner portion defined by the cut line and one side of the surface base material is a peeling start portion. Used as. And the said cut line which divides the corner | angular part which is a peeling start part, and the peripheral part along one side are made into the said non-adhesion part, for example.

  It is preferable that two non-adhesive portions are provided along the peripheral edge of the label portion, and a portion between the two non-adhesive portions is used as a peeling start portion. Moreover, it is preferable that a non-adhesion part is provided adjacent to a peeling start part.

The surface substrate is, for example, kraft paper, fine paper, glassine paper, or thermal paper having a basis weight of 15 to 80 g / m ² . The non-adhesive part is formed, for example, by not providing the pressure-sensitive adhesive layer partially, or is formed by covering a part of the surface of the pressure-sensitive adhesive layer to be adhered to the adherend with a non-adhesive material.

  In the present invention, it is possible to prevent tearing of the surface base material that occurs when the surface base material is peeled off from the pseudo-adhesive layer by eliminating a part of the adhesive force at the periphery of the label portion. Further, by maintaining the adhesive strength at the peeling start portion, the label portion can be easily peeled from the pseudo adhesive layer at the start of peeling.

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 the first embodiment of the present invention. As shown in FIG. 1, the pseudo-adhesive label 10 is formed by laminating a surface base material 11, a pseudo-adhesion layer 12 that is pseudo-adhered to the surface base material 11, and an adhesive layer 13 in this order. A release substrate 14 is adhered to the pressure-sensitive adhesive layer 13. The pseudo-adhesive label 10 is used by being peeled off from the pressure-sensitive adhesive layer 13 by the peeling substrate 14 and being stuck to an adherend with 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. In the pseudo-adhesive label 10 attached to the adherend, the surface base material 11 is peeled from the pseudo-adhesion layer 12.

As the surface substrate 11, for example, craft paper, fine paper, glassine paper, thermal paper, parchment paper, rayon paper, coated paper, and the like are used. Preferably, craft paper, fine paper, glassine paper, or thermal paper is used. used. Although the basic weight of the surface base material 11 is 10-100 g / m < ² >, for example, it is preferable that it is 15-80 g / m < ² >. In the present embodiment, the surface base material 11 is peeled off from the pseudo-adhesive layer 12 without causing tearing even when the surface base material 11 having a small basis weight and fragile and thin is used. It is possible. The surface base 11 is used as a surface on which information such as characters is displayed on the surface.

  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, 10-50 micrometers, Preferably it is 15-40 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. When the release agent layer is provided, the surface base material 11 is peeled off at the interface between the pseudo adhesive layer 12 and the release agent layer.

  The pressure-sensitive adhesive layer 13 is a layer that is provided on the back side of the pseudo-adhesive layer 12 and adheres the pseudo-adhesive label 10 to the 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 conventionally known pressure sensitive adhesives such as adhesives and silicone pressure sensitive adhesives. 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. Although the thickness of the peeling base material 14 is not specifically limited, For example, it is 20-200 micrometers, Preferably it is 40-100 micrometers.

  The pressure-sensitive adhesive layer 13 is formed, for example, by applying a pressure-sensitive adhesive to the surface of 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 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.

  A half-cut line 20 is provided on the surface base material 11. The half-cut line 20 is cut from the surface of the surface base material 11 to the front of the pseudo adhesive layer 12. That is, the surface base material 11 is cut to the back surface by the half-cut line 20. For example, when the release agent layer is coated on the back surface of the surface base material 11, the release agent layer is also cut by the half-cut line 20. Is included. The half-cut line 20 may be formed in a perforated shape, or may be formed from a single slit.

  FIG. 2 is a plan view schematically showing the pseudo-adhesive label according to the first embodiment of the present invention. As shown in FIGS. 1 and 2, the pseudo-adhesive label 10 is unnecessary by raising the scrap after the surface base material 11, the pseudo-adhesive layer 12, and the pressure-sensitive adhesive layer 13 are punched and cut by punching. The portion is removed from the peeling substrate 14 and is formed into a substantially rectangular label having the upper side 10A and the lower side 10B as long sides and the left and right side sides 10C and 10D as short sides. The pseudo-adhesive label 10 is subjected to a half-cut process as well as a punching process, and the above-described half-cut line 20 is also formed. The punching process and the half-cut process are performed by die cutting, for example, but may be performed by laser irradiation or the like.

  The half-cut line 20 extends vertically from the upper side 10A to the lower side 10B. The surface base material 11 can be separated and separated into left and right rectangular sheets (hereinafter referred to as label portions 21 and 22) by a half-cut line 20. Each of the label portions 21 and 22 is peeled off from the pseudo adhesive layer 12 starting from one of the four corner portions 21A to 21D and 22A to 22D of the label portions 21 and 22, and the corner portions 21A to 21D. 22A to 22D are used as the peeling start part.

  In this embodiment, the pressure-sensitive adhesive is partially applied, and the pressure-sensitive adhesive layer 13 is partially provided in the pseudo adhesive label 10. Thereby, the label parts 21 and 22 are provided with a non-adhesive part 23 that is not adhered to the adherend via the adhesive layer 13 and an adhesive part 24 that adheres to the adherend via the adhesive layer 13. Specifically, the peripheral portions 21S and 22S of the label portions 21 and 22 and the portions excluding the corner portions 21A to 21D and 22A to 22D are not provided with the adhesive layer 13 at positions corresponding to them, It becomes the adhesive part 23. On the other hand, the inner regions 21N and 22N and the corner portions 21A to 21D and 22A to 22D, which are regions inside the peripheral portions 21S and 22S, are provided with the adhesive layer 13 at positions corresponding to them, Become.

  That is, all the portions except for the corner portions 21A to 21D and 22A to 22D are the non-adhesive portions 23 in the peripheral portions 21S and 22S along the four sides 10A to 10D and the half cut line 20 of the pseudo adhesive label 10. And in each label part 21 and 22, each edge | side 10A-10D and the non-adhesion part 23 formed along the half cut line 20 each exhibit the rectangular shape which has a fixed width, The both ends are peeling start parts ( That is, it is adjacent to the corner portion of the label portion. In addition, the width | variety of the non-adhesion part 23 is about 0.1 mm-10 mm, for example, Preferably it is about 0.5 mm-5 mm.

  However, the non-adhesive portion 23 may be formed by so-called paste killing. In this case, the non-adhesive part 23 is formed by covering the part of the adhesive layer 13 corresponding to the non-adhesive part 23 with the non-adhesive material. Paste killing is performed, for example, after the pseudo adhesive label 10 is formed and before punching. Specifically, after the peeling base material 14 is peeled from the pressure-sensitive adhesive layer 13 and a non-sticking material is applied to one surface of the pressure-sensitive adhesive layer 13 peeled from the peeling base material 14 to form the non-sticking portion 23, The peeled substrate 14 that has been peeled off is attached to the pressure-sensitive adhesive layer 13 again. The non-adhesive material used in the paste killing is not particularly limited, and is, for example, a commonly used non-adhesive resin material such as printing ink or varnish.

  Next, the operation of the pseudo adhesive label 10 according to this embodiment will be described. In the pseudo-adhesive label 10 affixed to the adherend, the label portion 21 starts to peel from the corner portion 21C, for example, and is pulled diagonally downward to the left in FIG. Here, the portion along the upper side 10 </ b> A of the label portion 21 and the half-cut line 20 is formed as a non-adhesive portion 23, and the pseudo adhesive layer 12 is not adhered to the adherend by the adhesive layer 13. Therefore, when the label portion 21 is peeled off, the pseudo adhesive layer 12 rises following the label portion 21 (that is, the surface base material 11) in the portion along the upper side 10A and the half cut line 20, and the pseudo adhesive layer 12 The peeling angle of the surface base material 11 becomes small. When the peeling angle becomes small in this way, the peeling resistance when peeling the surface base material 11 becomes small, and the surface base material 11 is prevented from being broken at portions along the upper side 10A and the half-cut line 20.

  On the other hand, since the inner region 21N of the label portion 21 is adhered to the adherend by the adhesive layer 13, the peeling resistance in the inner region 21N is relatively high. However, the tearing of the surface base material 11 occurs with the peripheral portion 21S as the starting point, and hardly occurs with the inner region 21N as the starting point. For this reason, in the present embodiment, only the peripheral portions 21S and 22S of the label portions 21 and 22 are set as the non-adhesive portions 23, thereby preventing the label portion 21 from being broken.

  Further, the pseudo adhesive layer 12 is adhered to the adherend by the pressure-sensitive adhesive layer 13 in the corner portion 21 </ b> C that is a peeling start portion. It is relatively easy to peel off the label portion 21 (surface base material 11) from the pseudo-adhesive layer 12 attached to the adherend, and therefore, the peeling of the label portion 21 starts easily from the corner portion 21C. Can do. Furthermore, in this embodiment, since corner part 21A-21D is adhere | attached on the adherend as the adhesion part 23, the label turning in corner part 21A-21D is also prevented.

  In addition, when the label part 21 starts peeling from the other corners 21A, 21B, and 21D, or when the label part 22 peels, the behavior when the label part 21 starts peeling from the corner 21C is also the behavior. Since it is the same as that, its description is omitted.

  FIG. 3 is a plan view of the pseudo-adhesive label 10 according to the second embodiment of the present invention. Hereinafter, the difference between the second embodiment and the first embodiment will be described. In the first embodiment, the corners 21 </ b> A to 21 </ b> D and the corners 22 </ b> A to 22 </ b> D are used as peeling start portions, but in this embodiment, the corners 21 </ b> C and 22 </ b> C partitioned by the upper side 10 </ b> A and the half-cut line 20. Only is used as a peeling start part. In the present embodiment, in order to indicate that the corner portions 21C and 22C are peeling start portions, the surface base material 11 and the peeling base material 14 indicate that the corner portions 21C and 22C are peeling start portions by arrows or the like. It is preferable that tabs or the like are provided on the corners 21C and 22C.

  Moreover, the non-adhesion part 23 is provided only in the peripheral parts 21S and 22S of the label parts 21 and 22 similarly to 1st Embodiment. However, in the present embodiment, the non-adhesive portion 23 is provided only in the peripheral portions 21S and 22S along the upper side 10A and the half cut line 20 of the pseudo adhesive label 10 and excluding the corner portions 21C and 22C.

  In the pseudo-adhesive label 10 adhered to the adherend, the label portions 21 and 22 are peeled off from the pseudo-adhesive layer 12 by being pulled downward and to the lower right with the corner portions 21C and 22C as peeling start portions. . Also in this embodiment, the label portions 21 and 22 can be peeled off from the pseudo-adhesive layer 12 without causing breakage by forming part of the peripheral portions 21S and 22S as the non-adhesive portion 23. Further, since the adhesive portions 24 are provided at the corner portions 21C and 22C, the label portions 21 and 22 can be easily peeled from the pseudo adhesive layer 12 at the start of peeling.

  In the present embodiment, the peripheral portions 21S and 22S along the lower side 10B and the side sides 10C and 10D are not formed as the non-adhesive portion 23. However, the portions along the sides 10B to 10D are peeled after the label portions 21 and 22 are peeled off by half or more. Therefore, when a portion along the sides 10B to 10D is peeled off, no high peeling resistance is generated, so that the surface base material is not broken. That is, even if the non-adhesive part 23 is not provided over substantially all of the peripheral part of the label part, the peripheral part 21S ( Alternatively, if there are two along the peripheral edge portion 22S), the surface base material can be sufficiently prevented from being broken.

  In the present embodiment, the non-adhesive portion 23 is provided along the upper side 10A and the half-cut line 20 up to the side sides 10C, 10D, or the lower side 10D. Accordingly, the corner portions 21A, 22A, 21D, and 22D are formed as the non-adhesive portion 23, but these may be formed as the adhesive portion 24 as in the first embodiment.

  Further, in each of the above embodiments, the pseudo-adhesive label 10 is provided with the half-cut line 20, and a part of the surface base material 11 is separated and separated from the other part as the label part 21 (or label part 22). ing. However, the half cut line 20 may not be provided, and the entire surface base material 11 may be peeled from the pseudo adhesive layer 12 as one label portion.

  In each of the embodiments described above, the label portion is substantially rectangular, but the shape is not limited to a rectangle, and may be another polygon such as a triangle, or may be a circle or the like. However, even in cases other than the rectangular shape, at least two non-adhesive portions 23 are provided along the peripheral edge portion of the label portion, as in the above embodiments, and between the two non-adhesive portions 23. It is preferable that the adhesive part 24 used as a peeling start part is provided. Further, similarly to the above embodiments, it is preferable that the non-adhesive portion 23 is adjacent to the peeling start portion, and the corner portion of the label portion is used as the peeling start portion.

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