Description

  The present invention relates to a concealment label that is affixed to a postcard information entry field and peeled off from a postcard using a label peeling device.

  2. Description of the Related Art Conventionally, postal items that require concealment of personal information entered on a postcard, such as an account transfer application form, a dividend transfer designation form, and a voting right exercise form, are known. For this type of mail, the sender usually puts a reply postcard and concealment label in an envelope and delivers it to the user's hand, and the user fills in the information entry field of the reply postcard and then the concealment label on it. Is pasted and sent back to the sender. The sender who received it removes the concealment label from the postcard with label, reads the information entered in the information entry column, and performs the paperwork.

  Conventionally, the concealment label peeling process on the sender side has been performed manually. However, if the amount of the concealment label to be peeled is large, the burden on the operator becomes great. Therefore, in order to reduce the burden on the operator, in recent years, a label peeling apparatus that can automatically peel off the concealment label without using manual work is used (for example, see Patent Document 1 below).

  The above-mentioned label peeling device is characterized in that a pressure-sensitive adhesive-coated release tape is applied onto a postcard with a label, pressure is applied to both, and the pressure is applied to the release tape by pulling the release tape. The concealment label is peeled off from the postcard. However, in the peeling process using this label peeling device, when the paper width of the concealment label is wide, since the resistance at the start of peeling is large, the peeling tape is detached from the concealment label, and the concealment label is peeled off successfully from the postcard. There was something I couldn't do. Also, if too much pressure is applied to increase the pressure-bonding strength between the release tape and the concealment label, the curl that occurs on the postcard after peeling will become tight depending on the direction of paper fiber flow (hereinafter referred to as “paper grain direction”). There was also a problem of becoming.

  The present invention has been made to solve the above-mentioned problems. In a concealed label that is peeled off from a postcard by using a label peeling device, the postcard can be smoothly peeled off and the postcard is curled after being peeled off.

  According to the present invention, the peeling direction by the peeling tape is set so as to be parallel to the paper direction of both the vertical and horizontal eyes of the postcard. It becomes possible to start peeling, and it is not necessary to align the direction of the postcard with a label when setting in the label peeling apparatus, and the peeling process can be performed more efficiently.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  First, the structural example of the concealment label concerning this invention is demonstrated based on FIGS.

  The concealment label 10 shown in FIGS. 1 to 3 is a postcard-specific label in which the paper grain direction A of the postcard 30 is a vertical grain, and the peeling direction B of the concealment label 10 is the vertical grain of the postcard 30 as described below. Is set to be parallel to. The reason for matching the paper grain direction A of the postcard 30 with the peeling direction B of the concealment label 10 is to prevent the postcard 30 from curling after peeling.

  The concealment label 10 is detachably attached to the release paper 20 until use. At the time of use, the concealment label 10 peeled off from the release paper 20 is attached to the postcard 30 so as to conceal the information entry field 31 and label peeling described later. It is peeled off from the postcard 30 using the device 50. The standard size of the postcard 30 is approximately 150 mm long × 100 mm wide, but the size of the concealment label 10 is smaller than that and is set within a range of 70-150 mm long × 70-100 mm wide.

  As the label substrate 11, various papers such as high-quality paper, art paper, and coated paper, and resin films such as a polyester film and a polypropylene film are used, and the size is determined according to the size of the concealment label 10. Further, in order to reduce the resistance when peeling the concealment label 10 from the postcard 30 and make it easy to peel off, a peeling opening formed in a trapezoidal shape, a triangular shape, a quadrangular shape or the like may be provided at the upper end portion of the label base material 11.

  A concealing layer 12 is printed on the surface of the label substrate 11. The concealing layer 12 is obtained by applying anti-transmission printing to the label base material 11 in order to conceal the information entry field 31 of the postcard 30. For example, the label base material 11 is made of a dark color ink such as black, blue, or dark blue. It is formed by solid printing or tint block printing, and the characters on the back side of the label base 11 are not transparent.

  On the surface of the label base material 11, the concealing layer 12 is not printed at a peeling start position and a peeling end position by a peeling tape 40 described later, and an exposed portion 13 exposing the label base material 11 is provided. The size of the exposed portion 13 is set to a width of 25 mm or more and a height of 7 mm or more in accordance with the width of the release tape 40. In this example, the exposed portions 13 are provided at the peeling start position and the peeling end position, but it is not always necessary to provide them at both positions, as long as they are provided at least at the peeling start position. The reason why the exposed portion 13 is provided is that when the masking layer 12 is printed up to the peeling start position, the pressure-sensitive adhesive 42 applied to the peeling tape 40 attracts only the masking layer 12, and the masking label 10 This is because peeling may not be performed normally. If the exposed portion 13 is provided, the pressure-sensitive adhesive 42 is not pressed against the label base material 11 and is not detached from the concealment label 10, and the concealment label 10 is reliably peeled off.

  An adhesive layer 14 is coated on the back surface of the label substrate 11. The pressure-sensitive adhesive layer 14 has re-peelable and re-adhesive adhesive strength, and after the concealment label 10 is peeled off from the release paper 20 and attached to the postcard 30, the concealment label 10 can be peeled off from the postcard 30 and again. It is also possible to paste. As the pressure-sensitive adhesive to be used, an acrylic emulsion type pressure-sensitive adhesive is preferable if the label base 11 is paper, but if the label base 11 is a resin film, a solvent-type acrylic or rubber-based (natural rubber, SBR) is used. , Butyl rubber), hot melt type, silicone type and other various pressure-sensitive adhesives may be used.

  In this example, the adhesive force of the pressure-sensitive adhesive surface is adjusted by applying a so-called paste-killing process in which the pressure-sensitive adhesive layer 14 coated on the entire surface of the label substrate 11 is partially covered. An acrylic emulsion-type pressure-sensitive adhesive layer 14 is applied to the entire back surface of the label substrate 11, and a UV-curable ink containing a silicone component is scattered on the release paper 20 so that the release paper 20 and the concealing label are applied. The halftone dots 15 are transferred onto the pressure-sensitive adhesive layer 14 by laminating 10. It is also possible to improve the concealment property by using a dark color ink such as black, blue or dark blue as the ultraviolet curable ink constituting the halftone dot portion 15 or by applying a tint block printing.

  As a method for adjusting the adhesive force on the adhesive surface, instead of the above-described paste-killing process, a method is adopted in which a pressure-sensitive adhesive is applied to the back surface of the label substrate 11 and adjusted by the coating area of the adhesive layer 14. Also good. Alternatively, the ratio of tackifiers (polyterpene, rosin ester resin, etc.) contained in the pressure-sensitive adhesive may be reduced, and a weak pressure-sensitive adhesive whose adhesive strength is adjusted in advance may be directly applied to the back surface of the label substrate 11.

  About the back surface of the label base material 11, the ink is applied on the pressure-sensitive adhesive layer 14 along the edge on the peeling start side so as to be perpendicular to the peeling direction B. A weak adhesive portion (hereinafter referred to as “first weak adhesive portion”) 16 that is covered to weaken the adhesive force is provided. The first weak adhesive portion 16 is intended to reduce the initial resistance at the start of peeling and facilitate peeling. Further, a weak adhesive part (hereinafter referred to as “second weak adhesive part”) in which the ink is applied in a strip shape on the adhesive layer 14 from the peeling start position to the peeling end position and the adhesive layer 14 is coated to weaken the adhesive force. ) 17 is provided. The second weak adhesive portion 17 is for reducing the resistance during peeling and facilitating peeling.

  The size of the first weak adhesive part 16 may be at least 2 mm or more in width, and the size of the second weak adhesive part 17 may be 25 mm or more in width. As the ink constituting these weak adhesive portions 16 and 17, an ultraviolet curable ink containing a silicone-based component is suitable like the halftone dot portion 15, and the first weak adhesive portion 16 and the second weak adhesive portion 17. The adhesive strength in each region is set to 20 mN / 25 mm or less (measured by 180 ° peel method according to JIS-Z0237). Further, the area of the combined area of the halftone dot portion 15 and the weak adhesive portions 16 and 17 occupies at least 70% or more of the entire area of the adhesive surface. This is to prevent the adhesive surface of the concealment label 10 from being firmly adhered to the postcard 30 and causing excessive resistance during peeling.

  Next, a modified example of the concealment label according to the present invention will be described with reference to FIGS.

  The concealment label 10 shown in FIG. 4 is a label dedicated to a postcard with the paper direction A as a horizontal plane, and is set so that the peeling direction B of the concealment label 10 is parallel to the horizontal direction of the postcard 30. The point that the concealing layer 12 is printed on the surface of the label base material 11 and the point that the adhesive layer 14 with adjusted adhesive force is applied to the back surface of the label base material 11 are the same as the concealment label 10 shown in FIGS. Detailed description will be omitted because it is the same.

  The exposed portion 13 is provided on the surface of the label base material 11 at the peeling start position and the peeling end position, respectively. However, in this example, the peeling direction B is parallel to the horizontal eye, so It is set at the center of both left and right ends. Further, the first weak adhesive portion 16 is provided on the back surface of the label base material 11 along the edge on the peeling start side so as to be perpendicular to the peeling direction B, and the second weak adhesive portion 16 extends from the peeling start position to the peeling end position. In this example, the first weak adhesive portion 16 is provided along the left edge portion of the adhesive surface, and the second weak adhesive portion 17 crosses the center of the adhesive surface. Is provided.

  The concealment label 10 shown in FIG. 5 is a dual-purpose label that can be peeled off regardless of whether the paper direction A of the postcard 30 is vertical or horizontal, and the peel directions B1 and B2 of the concealment label 10 are postcards 30. Are set so as to be parallel to both the grain directions A1 and A2 of the vertical and horizontal eyes.

  That is, the exposed portion 13 on the surface of the label substrate 11 is set at the center of all the top, bottom, left, and right edges of the label substrate 11. Moreover, the 1st weak adhesion part 16 is provided in the back surface of the label base material 11 along the peripheral four sides of the adhesion surface. Further, the second weak adhesive portion 17 is provided so as to be orthogonal to each other by longitudinally cutting the adhesive surface from the center of the upper and lower edge portions and crossing the adhesive surface from the center of the left and right edge portions.

  The above is the configuration of the concealment label according to the present invention. Next, usage examples of the concealment label will be described with reference to FIGS.

  There are various possible uses for the postcard 30, but in this example, it was applied to an account transfer application form as shown in FIG. In the drawing, an information entry field 31 of an account transfer application form is provided on the communication side of the postcard 30, and the address of the sender is printed in advance on the address side (not shown). The postcard 30 uses a paper with a grain direction A which is vertical. The postcard 30 and the vertical label 10 shown in FIG. 1 are enclosed in an envelope and delivered to the user. It is done.

  The user first enters predetermined items such as address, name, contact information, designated financial institution name, and account number in the information entry field 31. Next, the concealment label 10 is peeled off from the release paper 20 in order to conceal the entered information entry field 31. Here, since the adhesive strength of the adhesive surface of the concealment label 10 is weakened by the above-described paste-killing process, it can be peeled off from the release paper 20 without difficulty. Then, the peeled concealment label 10 is attached to the information entry field 31 of the postcard 30. Since the exposed portions 13 of the concealment label 10 are arranged in the vertical direction of the label base material 11, the peeling direction B is attached in a state parallel to the vertical eyes of the postcard 30. Then, the user attaches the concealment label 10 to the postcard 30 in this way and mails it with the personal information concealed.

  On the other hand, the recipient of the postcard (hereinafter referred to as “postcard with label”) 30-1 to which the concealment label 10 is attached peels off the concealment label 10 from the postcard with label using the label peeling device 50. The personal information entered in the information entry column 31 is read and paperwork is performed. FIG. 7 shows the configuration of the label peeling device 50. This device is a postcard transport unit 51, a tape supply unit 52, a tape crimping unit 53, a label peeling unit 54, a label winding unit 55, and a postcard discharge. And a portion 56.

  The postcard transport unit 51 includes a pair of transport rollers 51 a and 51 b, and transports the postcards 30-1 with labels one by one and supplies them to the tape press unit 53. In the postcard transport unit 51, a plurality of labeled postcards 30-1 are stacked and set. At this time, the orientation of the postcards 30-1 with labels is aligned vertically and the paper direction A of the postcard 30 is made to coincide with the transport direction. Set with the surface to which the concealment label 10 is attached facing upward. The labeled postcard 30-1 passes between the transport rollers 51 a and 51 b one by one and is supplied to the tape crimping unit 53.

  The tape supply unit 52 pulls out the peeling tape 40 wound in a roll shape around the tape roller 52 a and supplies it to the tape pressing unit 53. Here, as the release tape 40, a tape base 41 made of glassine paper, an OPP film, a PET film or the like is coated with a pressure sensitive adhesive 42 mainly composed of an acrylic resin. In the tape supply unit 52, the release tape 40 wound in a roll is set on the tape roller 52a, and the release tape 40 fed from the tape roller 52a is tape-bonded with the pressure-sensitive adhesive 42 on the back side facing downward. Supplied to the unit 53.

  The tape crimping part 53 is composed of a pair of crimping rollers 53a and 53b, and crimps the peeling tape 40 to the postcard 30-1 with label. In the tape crimping unit 53, the postcard with label 30-1 conveyed from the postcard conveying unit 51 and the peeling tape 40 supplied from the tape supply unit 52 merge, and both the concealment label 10 and the pressure sensitive adhesive 42 are present. It passes between the pressure-bonding rollers 53a and 53b while facing each other. In the postcard 30-1 with the label and the peeling tape 40 after passing between the pressure rollers 53a and 53b, the peeling tape 40 cuts the center of the concealment label 10 along the vertical lines of the postcard 30 as shown in FIG. In addition, the pressure-sensitive adhesive 42 on the back surface of the peeling tape 40 is pressed by the pressure-bonding rollers 53a and 53b so that the pressure-sensitive adhesive 42 is pressure-bonded to the masking layer 12 and the exposed portion 13 of the masking label 10, respectively.

  The label peeling unit 54 includes a peeling tool 54a and a pulling roller 54b. The label peeling unit 54 peels the concealment label 10 from the postcard 30 by the peeling tool 54a while pulling the peeling tape 40 by the pulling roller 54b. In the label peeling part 54, the peeling tape 40 is pulled by the pulling roller 54b in a direction away from the conveying direction of the postcard 30. At this time, the upper surface of the postcard 30-1 with label is pressed by a peeling tool 54a having a roller attached to the tip. It is attached. Therefore, the postcard 30-1 with a label to which the release tape 40 is pressure-bonded is connected via a pressure-sensitive adhesive surface P2 between the pressure-sensitive adhesive 42 and the pressure-sensitive adhesive surface P1 between the exposed portion 13 and the pressure-sensitive adhesive layer P1. Is peeled off. In addition, in order to prevent the postcard 30 from being wound up, the postcard 30 after being peeled is pressed by a plate-like peeling aid 54c, and the conveyance direction is restricted.

  The label winding unit 55 includes a winding roller 55a, and the concealment label 10 peeled off from the postcard 30-1 with label is wound into a roll by the winding roller 55a while being pressed against the peeling tape 40. . On the other hand, a box 56a is set in the postcard discharge unit 56, and the postcard 30 after the concealment label 10 is peeled is collected in the box 56a.

  In this way, the concealment label 10 is peeled off from the postcard 30-1 with a label, but in this example, the pressure sensitive adhesive 42 of the peeling tape 40 is securely pressed against the exposed portion 13 of the concealment label 10, so that at the time of peeling Only the concealment layer 12 is not attracted, and the peeling tape 40 can lift the label base material 11, and the concealment label 10 is reliably peeled off. Moreover, since the 1st weak adhesion part 16 and the 2nd weak adhesion part 17 extended in a peeling direction are provided in the back surface of the concealment label 10 along the edge part by the side of peeling start, peeling Both the initial resistance at the start and the resistance during peeling are small, and a very smooth peeling process is possible. Furthermore, since the peeling process is performed in the direction in which the peeling direction B by the peeling tape 40 is parallel to the paper grain direction A of the postcard 30, curling of the postcard 30 after peeling can be effectively prevented.

  The example described above is an example in which the paper grain direction A of the postcard 30 is vertical, but when the paper grain direction A is horizontal, the concealment label 10 dedicated to the horizontal eye shown in FIG. 4 is used. Since the exposed portions 13 of the concealment label 10 are arranged in the lateral direction of the label base material 11, the peeling direction B becomes parallel to the lateral eye of the postcard 30 when it is attached to the postcard 30. Moreover, when peeling with the label peeling apparatus 50, the direction of the postcard 30-1 with a label is set with horizontal orientation, and the paper grain direction A of the postcard 30 is made to correspond with a conveyance direction. As a result, the postcard 30-1 with the label and the peeling tape 40 after passing between the pressure-bonding rollers 53a and 53b cross the center of the concealment label 10 along the horizontal line of the postcard 30. Therefore, since the peeling process is performed in the direction in which the peeling direction B by the peeling tape 40 is parallel to the horizontal line of the postcard 30, curling of the postcard 30 after peeling can be prevented as in the case of the vertical eye.

  When the concealment label 10 used both vertically and horizontally as shown in FIG. 5 is used, it is possible to start peeling from any of the top, bottom, left and right edges of the concealment label 10, so that the label is set in the label peeling device 50. At this time, it is not necessary to align the directions of the postcards 30-1 with labels, and the peeling process can be performed more efficiently.

The structural example of the concealment label which concerns on this invention is shown, (a) is the top view seen from the surface side, (b) is the top view peeled off from the release paper and seen from the back surface side. 1 shows the concealment label of FIG. 1, wherein (a) is a cross-sectional view taken along the line aa in FIG. 1, and (b) is a cross-sectional view taken along the line bb in FIG. It is a top view which shows the dimension of the concealment label of FIG.
