Description

  The present invention relates to an adhesive-attached paper piece used as a mark of a specific page of a book or used as a memorandum.

  Conventionally, a sticky note in which a plurality of paper pieces each provided with an adhesive layer on the back surface are overlapped to form a laminate is known. In such a sticky note, the surface is subjected to a surface treatment such as applying a release agent so that each piece of paper can be peeled off one by one, that is, in order to improve the peelability of the adhesive layer from the paper piece surface. Is common. However, in spite of such processing, the peeled paper piece may be greatly curved at the adhesive layer portion. This bending phenomenon of the paper piece is caused by the paper piece being bent by the force applied to the paper piece when the paper piece is peeled off, and the curved state being held by the adhesive layer.

In order to solve such a problem, for example, in the device described in Patent Document 1, the adhesive layer is divided in the lateral direction of the paper piece, and the adhesive layer and the exposed portion of the paper piece surface are alternately arranged. In this case, for example, the adhesive layer is elongated in the vertical direction so that it is not easily peeled off when it is attached to a book page, that is, in use.
Japanese Utility Model Publication No. 3-27816

  However, since the adhesive layer is only discontinuous in the lateral direction in such a configuration, the adhesive force in the lateral direction may be reduced in use as compared with the conventional one. Therefore, there is a high possibility that the sticky note will be peeled off from the part where the sticky note is attached during use.

  Further, although the adhesive layer is not continuous in the lateral direction, the adhesive layer may be curved in the same manner because the adhesive layer extends in the peeling direction. In other words, although the adhesive layer area decreases and the adhesive force also decreases, the adhesive force in the peeling direction is substantially the same in the direction in which the adhesive layer extends, so each end region of the paper piece provided with the adhesive layer The adhesive layer acts to maintain the curvature of the paper piece. Therefore, the malfunction at the time of use was not improved so much by such a curvature and the fall of adhesive force.

  In view of the above problems, an object of the present invention is to provide an adhesive-attached paper piece that can maintain a predetermined adhesive force without a region corresponding to an adhesive layer being curved during use.

In other words, the adhesive-attached paper piece of the present invention is used as a sticky note by laminating a plurality of sheets, and includes a peripheral portion having a first end portion and a second end portion facing the first end portion. An adhesive-attached paper piece comprising an adhesive portion to which an adhesive is applied and a non-adhesive portion where the fabric is exposed, wherein the adhesive portion is applied with an adhesive in a set shape. It is composed of a plurality of unit adhesion regions that are spaced apart from each other at a predetermined interval in the horizontal direction and the vertical direction, and the non-adhesion portion is formed in a net shape between the unit adhesion regions, thereby forming the adhesion portion. wherein each unit bonding area is not continuous stress in a direction of peeling is surrounded by the non-adhesive portion, which paper is formed along curved hardly a Rutotomoni, at least a portion of the periphery of , Almost the entire back side of the book page, document, or file In order to prevent the adhesive portion from sticking to paper or the like and partially lifting, the non-adhesive portion formed on the peripheral edge portion occupies most of the area of the back surface, and the second end portion side The area corresponding to 1.5 to 2 rows of the unit adhesion region is formed on the first end portion side so that the cloth is exposed.

  With such a configuration, for example, when a plurality of layers are detachably stacked, and when one of them is lifted from the non-bonded portion side and pulled away from the plurality of stacked paper pieces, the bonded portion is a net-like shape. Each non-adhesive part surrounds each unit adhesive region that constitutes the adhesive part, so there are a part (unit adhesive area) that is intended to hold the stress generated in the piece of paper with an adhesive and a part that cannot be held (non-adhesive part). It will be adjacent. That is, the stress generated in the adhesive is divided without being continuous in the separating direction. As a result, the adhesive portion does not hold the curvature of the paper piece, and the separated paper piece maintains a substantially flat shape without being curved. Therefore, it is possible to suppress floating from the side of the non-adhesive portion formed on at least a part of the peripheral edge in the usage state of the separated paper piece.

  In order to easily adjust the ratio between the total area of the unit bonded regions and the area of the non-bonded region in the bonded part, the unit bonded region is preferably circular, elliptical, or polygonal.

  Furthermore, the boundary portion between the bonded portion and the non-bonded portion that is formed along a part of the peripheral portion and functions as a turning portion is avoided from being linear, and the boundary is associated with the above-described separation operation. In order to avoid a straight crease (warp crease) from being attached to the part or to bend, the non-adhesive portion is formed as a first non-adhesive region formed in a net shape between the unit adhesive regions, A second non-adhesive region that is formed along at least a part of the peripheral portion and functions as a turning portion, and among the plurality of unit adhesive regions, a boundary portion with the second non-adhesive region The unit adhesive region disposed on the substrate may have the same shape as that of the unit adhesive region disposed at least on the part separated from the peripheral edge. If this is the case, the adhesive-attached paper piece arranged on the outermost part (for example, the uppermost part) of the adhesive-attached paper pieces in the laminated state is separated from the other adhesive-attached paper pieces to a specific page of the book, etc. When pasted and used, it is possible to prevent the occurrence of floating (warping or bending of a piece of paper) due to creases, and it is difficult to peel off and is excellent in practicality.

  In addition, the limitation that “the unit adhesion region arranged at the boundary portion with the second non-adhesion region has the same shape as the unit adhesion region arranged at least at the portion separated from the peripheral portion” is limited to the boundary. The unit adhesion region arranged in a part different from the part and in contact with the peripheral part lacks a part along the peripheral part (for example, the original circular shape becomes semicircular This is for the purpose of clarifying that such a partially bonded unit adhesion region is not the same shape. Moreover, it arrange | positions in the boundary part with the 2nd non-adhesion area | region which is formed along at least one part (for example, when a peripheral part consists of four sides, any one of four sides) and functions as a turning part. Of the unit bonded regions, a unit bonded region disposed at a portion in contact with a peripheral portion (for example, the other side intersecting the one side) may be a part cut along the peripheral portion.

  Moreover, as an aspect which produces the effect substantially the said effect, the said non-adhesion part is formed along the at least one part of the said 1st non-adhesion area | region formed in net shape between the said unit adhesion areas, and the said peripheral part. And a second non-adhesive region that functions as a turning portion, and among the plurality of unit adhesive regions, a boundary composed of unit adhesive regions arranged at a boundary portion with the second non-adhesive region A mode in which the site unit adhesion region group is not cut in a straight line substantially orthogonal to the turning direction can be mentioned.

  Here, the “turning direction” is a direction in which the outermost adhesive-attached paper piece is turned off from the other adhesive-attached paper pieces among the plurality of laminated adhesive-attached paper pieces. Even if the boundary part unit adhesive region group which is an aggregate of unit adhesive regions facing the second non-adhesive region is cut, if the cutting line is curved, corrugated or V-shaped The boundary part between the adhesive part and the second non-adhesive region functioning as the turning-off part can be prevented from being linear, and the boundary part is linearly folded along with the aforementioned separation work (turning work). It is difficult to attach (warp wrinkles), curving of a piece of paper can be suppressed, and a good pasting state on a predetermined page can be maintained.

  In such a configuration, it is preferable that the unit non-bonding region is circular or polygonal.

  The polygons of the unit bonded region and the unit non-bonded region are preferably a regular pentagon, a regular hexagon, or a Y shape.

  In addition, as an adhesive agent in this invention, the adhesive which makes it possible to paste a paper piece with an adhesive agent so that peeling is possible is included.

  The present invention is configured as described above. For example, when one sheet is pulled away from the stacked one, it is possible to prevent the separated sheet from being bent. Therefore, it is possible to suppress peeling without being lifted when used while being attached.

  Embodiments 1 to 3 of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the sticky note 1 of the first embodiment is formed by laminating a plurality of adhesive-attached paper pieces (hereinafter abbreviated as paper pieces) 2 having a substantially square shape. A stack of paper pieces 2 is used as a sticky note 1, but each paper piece 2 itself is a sticky note when used. Each paper piece 2 is provided with an adhesive portion 4 and a non-adhesive portion 5 on the back surface 3 which is one surface thereof, and the front surface 6 which is the other surface makes it easy to peel the stacked paper pieces 2. Is coated. The coating process itself may apply what is well known in this field. Moreover, it cannot be overemphasized that the shape of a paper piece is not limited to a square.

  The bonding portion 4 is provided on one side (hereinafter referred to as “first end portion 7”) side of the peripheral edge portion 30 of the back surface 3. In the first embodiment, as shown in FIG. 2, the bonding portion 4 includes a plurality of unit bonding regions 9 having a circular shape to which an adhesive is applied. In this embodiment, the diameter of each circular unit bonding region 9 is set to 4.5 mm. The unit bonding regions 9 are arranged in the bonding portion 4 so as to be separated from each other at a predetermined interval in the horizontal direction and the vertical direction of the paper piece 2. As a result, a net-like first non-bonding region 8 is formed between the unit bonding regions 9.

  On the other hand, the non-bonding portion 5 is provided on the second end portion 10 side facing the first end portion 7 in the first non-bonding region 8 and the peripheral portion 30 of the back surface 3 and functions as a turning portion. And a second non-adhesive region 8a. The first non-adhesive region 8 that is continuous in a net shape communicates with the second non-adhesive region 8a. The non-bonding part 5 has a smaller area than the bonding part 4. The non-adhesive portion 5 (specifically, the second non-adhesive region 8a) formed on the peripheral portion 30 is preferably as narrow as possible, and one of the stacked paper pieces 2 can be easily selected. It is set to have a width to obtain. This is because the adhesive portion 4 occupies most of the area of the back surface 3 and the entire back surface 3 sticks to the book page, document, or file cover to which the paper piece 2 is pasted during use, and the paper piece 2 is partially This is to prevent it from being lifted up. Specifically, for example, the non-adhesive portion 5 (second non-adhesive region 8a) formed in the peripheral portion 30 is 1.5 of the unit adhesive region 9 from the second end portion 10 side to the first end portion 7 side. The area corresponding to the lines 2 to 2 is formed so that the cloth of the paper piece 2 is exposed.

  In such a configuration, on the back surface 3 of the paper piece 2, the total area of the plurality of unit adhesion regions 9 with respect to the area of the first non-adhesion region 8 in the adhesion portion 4 is set to, for example, 1 to 2 times. 4 and the non-bonding part 5 are formed. The ratio of the total area of the unit bonding regions 9 to the area of the first non-bonding regions 8 is the density (number) of the unit bonding regions 9 in the bonding part 4 having a set predetermined area. Adjust by changing or both at the same time. Since the adjustment of the area ratio affects the adhesive strength in use, it is adjusted so that the adhesive strength is easy to peel off from the surface 6 of the paper piece 2 and difficult to peel off from the surface of uncoated paper or the like. is there. In addition, it is preferable to set the diameter of each unit adhesion area | region 9 in the range of 4.5 mm +/- 1.5mm.

  Then, a plurality of the paper pieces 2 having such a configuration are stacked in a state where the adhesive portion 4 is directed in the same direction, for example, downward, to form the sticky note 1. That is, the paper piece 2 is laminated by superimposing the adhesive portions 4 on the surface 6 coated with the underlying paper piece 2 with the first end portions 7 being aligned. Accordingly, each piece of paper 2 is laminated with the bonding portion 4 and the surface 6 in contact with each other, so that the individual pieces of paper 2 are individually separated by an external force smaller than the bonding force on the uncoated surface of the bonding portion 4 such as paper. Can be peeled off.

  In use, when the paper piece 2 is peeled off by applying a finger to the non-adhesive portion 5 (specifically, the second non-adhesive region 8a functioning as a turning-off portion), when an external force is applied to the paper piece 2, Stress is generated in the paper piece 2 in accordance with the external force. However, each unit adhesion region 9 forming the adhesion part 4 is surrounded by the first non-adhesion area 8 where the adhesive is not applied in a net shape, that is, the non-adhesion part 5, so that stress is applied in the direction of peeling the paper piece 2. It is not continuous, and therefore the paper piece 2 is difficult to bend (curl). Moreover, since the unit adhesive regions 9 are separated from each other by the first non-adhesive region 8, the adhesive does not act to reinforce the curved paper piece 2. Therefore, although the adhesive is applied to the adhesive portion 4 that occupies most of the back surface 3 of the paper piece 2, the paper piece 2 is not curved by the adhesive force of the adhesive. Therefore, at the time of use, the paper piece 2 can be stuck without lifting from the paper or the cover, and can be prevented from peeling off.

  The unit adhesion region 9 is not limited to the circular shape as described above. The unit bonding region 9 is, for example, an ellipse, a regular hexagonal polygon as shown in FIG. 3 (Modification 1), or a regular pentagon as shown in FIG. 4 (Modification 2). Further, it may be Y-shaped (Modification 3) as shown in FIG. In the case where the unit adhesion area 9 is a regular pentagon, all the unit adhesion areas 9 are arranged in addition to the modification 2 in which the unit adhesion areas 9 adjacent to each other in the horizontal direction of the paper piece 2 shown in FIG. It may be configured to be arranged in the same direction.

  In the case where the unit bonding area 9 of the modification 3 is Y-shaped, the modification 3 of the configuration in which all the unit bonding areas 9 are arranged in the same direction, and the second on the straight line parallel to the first end portion 7. A modification of the configuration in which a group arranged toward the end portion 10 and a group arranged toward the first end portion 7 on a straight line parallel to the first end portion 7 are alternately arranged in the direction of the second end portion 10. 3-1 (shown in FIG. 6). Specifically, as shown in FIG. 7, these Y-shaped unit adhesion regions 9 are formed by connecting a substantially square arm portion 12 to each side of the center portion 11 of the equilateral triangle and at the tip of the arm portion 12. The trapezoidal tip 13 is formed in a connected shape.

  Even in each of the first to third modifications described above, as described in the first embodiment, the adhesive force of the bonding portion 4 is adjusted by changing the size and density of each unit bonding region 9. It is.

  In the third embodiment, as shown in FIG. 9, an intra-region non-adhesion region 23 where the cloth of the paper piece 2 is exposed is formed in the unit adhesion region 9 in the first modification of the first embodiment described above. is there. Specifically, in the first modification of the first embodiment, a hexagonal intra-region non-adhesion region 23 that is similar to the unit adhesion region 9 and is smaller than the hexagon of the unit adhesion region 9 is formed in the unit adhesion region with the same center. 9 is formed. In other words, the third embodiment has a configuration in which the annular unit bonding regions 9 are arranged at predetermined intervals. The size of the intra-region non-adhesion region 23 is, for example, about ¼ of the unit adhesion region 9 because it reduces the adhesive force of the unit adhesion region 9.

  According to such a configuration, the unit adhesion regions 9 are further dispersed as compared with the first modification of the first embodiment. As a result, the stress generated when the paper piece 2 is peeled is further finely divided, and the paper piece 2 is not curved. Therefore, this Example 3 also has the same effect as Example 1.

  The configuration of the third embodiment can be applied to the first embodiment and the second and third modifications.

  In the fourth embodiment, as shown in FIG. 10, as compared with the first and third embodiments described above, the non-layer formed along at least a part of the peripheral portion 30 and functions as a turning portion. In order to avoid the boundary portion between the second non-bonding region 8a and the bonding portion 4 of the bonding portion 5 from being linear, the unit is disposed at the boundary portion between the second non-bonding region 8a that functions as a turning portion. The adhesion area 9 is different in that it has the same shape as the unit adhesion area 9 arranged at a site separated from the peripheral edge 30.

  That is, when each unit adhesion region 9 is circular, the unit adhesion region 9 arranged at the boundary portion with the second non-adhesion region 8a functioning as a turning portion of the non-adhesion portion 5 is also a complete circle. In addition, the unit adhesion area | region 9 arrange | positioned in the site | part which contact | connects parts other than the 2nd edge part 10 among the peripheral parts 30 among the unit adhesion area | regions 9 arrange | positioned in the boundary part with the 2nd non-adhesion area | region 8a is a peripheral part. A portion cut along the line 30 may be used. That is, it is only necessary to avoid that the boundary portion between the bonding portion 4 composed of the plurality of unit bonding regions 9 and the second non-bonding region 8a functioning as a turning portion is linear.

  Since it is such, compared with the aspect shown in FIG. 2, the boundary portion between the second non-adhesive region 8 a that functions as a turning portion and the adhesive portion 4 is not linear, and as a result, the laminated state During the work of separating the paper piece 2 on the other side from the other paper piece 2, it becomes difficult for the boundary portion to be attached with a linear crease (warp wrinkle), and the separated paper piece 2 is attached to a specific page of the book and used. At this time, it is possible to prevent the occurrence of lifting due to creases, and it is excellent in practicality without unexpectedly falling. Of course, as in the first and third embodiments, since the configuration of “the plurality of unit bonded regions 9 in which the bonding portions 4 are mutually dispersed” is adopted, the paper piece 2 is peeled off. The generated stress is finely divided, the paper piece 2 is not curved, and the fourth embodiment has the same effect as the first embodiment.

  Note that the configuration of the fourth embodiment can also be applied to the first to third modifications of the first embodiment and the third embodiment described above.

  For example, when the unit bonding area 9 is a polygon (Y-shaped in FIG. 6, regular hexagon in FIG. 11) as shown in FIGS. 6 and 11, the second non-bonding area 8 a functioning as the turning portion and Each of the unit bonded regions 9 arranged at the boundary portion of each of the unit bonded regions 9 has a peripheral portion (in the illustrated example, the second non-bonded region 8a in which the corner of each unit bonded region 9, that is, the portion that is not a side, functions as a turning portion. By arranging so as to face the second end portion 10), the boundary portion is prevented from being linear, and the above-described effects are exhibited.

  Also in the fourth embodiment, it is possible to adjust the adhesive force of the paper piece 2 by adjusting the size of each unit adhesion region 9, changing the density (number) thereof, or adjusting both of them simultaneously.

  In particular, as shown in FIG. 12, the density of the unit bonded region 9 disposed at the boundary portion with the second non-bonded region 8a of the non-bonded portion 5 that functions as a turning portion is set to a unit disposed at another portion. It is good also as an aspect made lower than the density of the adhesion | attachment area | region 9. FIG. With such an aspect, it becomes possible to more reliably avoid the boundary portion with the second non-adhesive region 8a from becoming linear, and the above-described effects can be made more effective.

  In the fifth embodiment, as shown in FIGS. 13 and 14, among the plurality of unit bonding regions 9, at the boundary portion with the second non-bonding region 8 a of the non-bonding portion 5 that functions as a turning portion. The boundary part unit adhesive region group composed of the unit adhesive regions 9 to be arranged is characterized in that it is not cut in a straight line substantially perpendicular to the turning direction (the arrow A direction shown in FIGS. 13 and 14). FIG. 13 shows a mode in which the boundary site unit adhesion region group is divided by a curved (partial arc) virtual cutting line L, and FIG. 14 shows the boundary site unit adhesion region group having a wave-like virtual cutting line L. It is the aspect delimited by. Here, the “boundary part unit bonded region group” means a set of unit bonded regions 9 facing the second non-bonded region 8a among the plurality of unit bonded regions 9, in other words, a unit facing (along) the virtual cutting line L. It is a set of adhesion regions 9.

  Even in such a case, it is possible to avoid substantially the same effect as the embodiment shown in the fourth embodiment, that is, to prevent the boundary portion between the bonded portion 4 and the second non-bonded region 8a from being linear. When the paper piece 2 positioned in the upper part is turned away from the other paper pieces 2, it becomes difficult to attach a linear crease (warp) substantially perpendicular to the turning direction to the boundary portion. When affixed to a specific page of a book or the like, it is possible to prevent the occurrence of lifting due to creases, and it is excellent in practicality without being unexpectedly dropped.

  The configuration of the fifth embodiment can also be applied to the first to third modifications of the first embodiment and the third embodiment described above.

  Further, in Example 5, the boundary part unit adhesion region group only needs to be cut in a straight line substantially orthogonal to the turning direction, and the boundary part unit adhesion region group has a V-shape in addition to the curved shape and the wave shape. It may be divided by a shape or a jagged virtual cutting line.

  In Example 5, it is also possible to adjust the adhesive force of the paper piece 2 by adjusting the size of each unit bonding region 9, changing its density (number), or adjusting both simultaneously. is there.

  Further, in each of the above embodiments, for example, as shown in FIG. 15, in the peripheral portion 30, a portion where the non-adhesive portion 5 (specifically, the second non-adhesive region 8 a) functioning as a turning portion is formed. The belt-shaped adhesive region 9a may be formed in a different part by applying the adhesive on the entire surface. The band-shaped adhesive region 9a is preferably formed in a portion (in the illustrated example, the first end portion 7) facing the portion (the second end portion 10 in the illustrated example) where the second non-bonded region 8a is formed. Of course, the area of the belt-like adhesive region 9a may be changed as appropriate according to the convenience and application.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
