  However, if such a habit is attached, the sticky note attached to the adherend is likely to float. In particular, in the sticky note, although the location of the pressure-sensitive adhesive layer is fixed to the adherend, the effect of the habit is unlikely to appear, but if the above-mentioned habit is formed at the boundary between the location of the adhesive layer and the location of the non-adhesive layer, It is not preferable because sticky notes are likely to float and cause sticking.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Note that the dimensional ratios in the drawings are exaggerated for the sake of explanation, and are different from the actual ratios.

  As shown in FIG. 1, the tag stack 100 of the embodiment has a configuration in which a plurality of tags 110 are stacked. Each tag 110 has a sheet-like base material 120 made of paper and an adhesive layer 130. The paper constituting the base material 120 is, for example, high quality paper, art paper, coated paper, kraft paper, or the like, but is not particularly limited. The pressure-sensitive adhesive layer 130 is formed on a part of one surface 121 of the substrate 120.

  The sticky notes 110 are adjacent to each other in the stacking direction D, and are releasably attached to the other surface 122 opposite to the surface 121 and the adhesive layer 130.

  The sticky note laminate 100 is curved at the boundary 103 between the adhesive portion 101 on which the adhesive layer 130 is formed and the non-adhesive portion 102, which is the other portion, and has a surface 121 at the outermost surface in the laminating direction D. One side 104 is concave, and the side 105 with the surface 122 on the outermost surface in the stacking direction D is convex.

  Next, a method for manufacturing the tag stack 100 will be described.

  The manufacturing method of the sticky note laminate 100 includes an adhesive application step and a lamination step, and further includes a bending step of bending the base material 120 after the lamination step.

  As shown in FIG. 2, in the adhesive application step, the adhesive 30 is applied to a part of one surface 121 of the base material 120. The application location of the adhesive 30 is not limited to one location, and may be a plurality of locations. The pressure-sensitive adhesive 30 is not particularly limited in what method it is applied. For example, the pressure-sensitive adhesive 30 may be applied by a printing technique such as rotary screen printing, or may be applied in a stripe shape along the application direction. The coating may be performed by stripe coating in which a plurality of processing locations are simultaneously formed.

  The pressure-sensitive adhesive 30 is, for example, an acrylic pressure-sensitive adhesive containing poly (meth) acrylate and tackifier as main components, but is not limited thereto, and another known pressure-sensitive adhesive may be used.

  As shown in FIG. 3, in the laminating step, a plurality of base materials 120 coated with the adhesive 30 are laminated side by side on a surface 121 and a surface 122 opposite to the surface 121 to form a laminate 10. In the laminate 10, the coated portions 11 of the adhesive 30 are arranged in the laminating direction D, and the uncoated portions 12 different from the coated portions 11 are arranged in the laminating direction D.

  Drying and curing of the adhesive 30 may be performed between the adhesive applying step and the laminating step, or may be performed after the laminating step. The adhesive layer 130 is formed by drying and curing the adhesive 30.

  As shown in FIG. 4, after the laminating step, the laminate 10 is cut by the coating unit 11 by the blade B, and divided into a plurality of laminates 10a. In the example shown in FIG. 4, the laminate 10 is divided into two laminates 10 a, but the number of divisions is not particularly limited. A larger number may be provided so that more than two stacked bodies 10a are formed. The bending step is performed, for example, after the formation of the laminate 10a.

  As shown in FIG. 5, in the bending step, a force F is applied to the laminate 10a, and at least at the boundary 13 between the coated portion 11 and the uncoated portion 12, the base material 120 is bent in the same manner as the above-described boundary 103. It is transformed into the shape which was done.

  The bending step was performed by applying a force F after the formation of the laminated body 10a, but is not limited thereto. At the same time as the formation of the laminated body 10a, the blade B moves the base material 120 from the surface 122 side to the surface 121 side. It may be performed using a pressing force. In this case, the pressing force of the blade B is equal to or higher than a force required to cut the plurality of stacked base materials 120 and to plastically deform the boundary 13 into a desired curved shape.

  If the base material 120 is bent using the pressing force of the blade B, the formation of the laminate 10a and the bending step can be performed simultaneously, and the working efficiency increases.

  Further, the bending step is not limited to a mode in which the base material 120 is bent by applying a force. For example, the base step is performed by utilizing a difference in expansion and contraction between one surface 121 and the other surface 122 of the base material 120. The material 120 may be curved at the boundary 13.

  As such a form, for example, it is conceivable to use a water-based emulsion-type adhesive as the adhesive 30.

  In this example, on one surface 121 of the base material 120 coated with the adhesive 30, since the moisture in the adhesive 30 is absorbed by the paper base material 120, the surface 121 is attached to the other surface 122. In comparison, it expands relatively largely, and shrinks during drying also becomes relatively large. By utilizing such a difference in expansion and contraction between the surfaces 121 and 122, the water amount and the drying conditions of the water-based emulsion-type adhesive may be adjusted so that the surface 121 side is concave and the surface 122 side is convex. However, the boundary 13 can be curved into a predetermined shape without necessarily applying the force F.

  Also, without using a water-based emulsion-type adhesive, for example, one surface 121 is made to contain more moisture than the other surface 122 by spraying or the like, or drying conditions are performed on the surfaces 121 and 122 using a heater or the like. It is possible to cause a difference in expansion and contraction between the surfaces 121 and 122 by other means such as changing the distance.

  Further, the bending step is not limited to the mode performed after the laminating step, and may be performed between the adhesive applying step and the laminating step. In this case, for example, before the laminating step, each base material 120 is curved at the boundary 13, and a plurality of the preformed base materials 120 are stacked in the laminating step.

  Regardless of whether the bending step is performed after the laminating step or before the laminating step, as a result, the curved shape of the boundary 103 in the tag stack 100 may be formed.

  Next, the operation and effect of the present embodiment will be described.

  As shown in FIG. 6, the sticky note stack 100 of the present embodiment is used with the sticky note 110 peeled off. At this time, it is common to peel off the sheet in such a manner that the sheet is turned, and such a method of peeling may be a factor that causes a curl-like habit.

  As shown in FIG. 7, the sticky note 110 </ b> A with such a habit is not preferable because when the sticky note 110 </ b> A is attached to the adherend S, it floats and causes factors such as peeling. Since the adhesive portion 101 is fixed to the adherend S, the influence of the habit is hard to appear, but if the boundary 103 is hazy, the entire non-adhesive portion 102 floats, and the habit is particularly easily affected.

  However, in the present embodiment, the curved shape pre-attached to the boundary 103 cancels the peculiarities that occur when the tag 110 is peeled off from the tag stack 100.

  For this reason, as shown in FIG. 8, the sticky note 110 is effectively suppressed from floating, and becomes substantially flat when attached to the adherend S.

  When the base material 120 is paper as in the present embodiment, a curl tends to be formed when the base material 120 is peeled off from the tag stack 100 as compared with a resin film, for example. It is particularly effective because the floating is suppressed even in a form that is easy to stick.

  In the bending step of bending the boundary 103, if the substrate 120 is bent by applying a force, for example, it is easy to adjust the magnitude of the force and the position at which the force is applied, and the substrate 120 is bent into a desired shape. Easy to do.

  On the other hand, in the bending step, if the base material 120 is curved by a difference in expansion and contraction between the one surface 121 and the other surface 122 of the base material 120, no force is required, and labor is reduced. You.

  The present invention is not limited to the above-described embodiment, and can be variously modified within the scope of the claims.

  For example, the base material 120 in the above embodiment is paper, but the present invention is not limited to this form, and includes a form in which the sheet-like base material is a resin film.

  Further, the size, shape, use, and the like of the tag are not particularly limited. For example, the tag is not limited to a substantially square shape as in the above embodiment, but may be an elongated rectangle. The sticky note may be in a relatively large form, for example, used for writing a memo, or may be a relatively small piece, for example, used as a bookmark.

  The adherend to which the tag is attached is not particularly limited, and may be, for example, paper such as a notebook or a book, resin such as a clear file, or metal. .

  The present invention also includes a form in which a support material such as a mount is arranged on one outermost side 104 of the sticky note laminate 100 and a form in which a cover is arranged on the other outermost side 105, for example. Included in the range.
