  The present invention relates to an open booklet in which a plurality of sheets are bound by bonding with one side thereof as a binding portion and opened with the binding portion as a center, and more particularly to a technique for avoiding unnecessary breakage of the sheet at the time of opening.

  Conventionally, in a booklet such as a catalog or a pamphlet, a plurality of sheets are overlapped and bound by bonding on one side thereof to form a spread. In such a booklet, there are a booklet composed of a plurality of sheets sandwiched between two cover sheets, or a booklet composed of only two sheets. A plurality of sheets are bound by bonding on one side.

  For example, Patent Document 1 discloses a booklet-like printed material that can be spread by sandwiching a plurality of booklet sheets between a pair of covers and breaking a perforation formed on one cover. Further, in Patent Document 2, two sheets are bonded at the periphery thereof, and a cut is formed inside the bonded adhesive margin, and the bag is opened by breaking the cut. It is disclosed.

  Thus, in a configuration in which a plurality of sheets are overlapped, a cut line such as a perforation is formed on the sheet to be exposed, and the open booklet that can be opened is formed by breaking the cut line. It is considered.

  11A and 11B are diagrams showing an example of a conventional open booklet, where FIG. 11A is a front view, FIG. 11B is a cross-sectional view taken along line AA ′ shown in FIG. 11A, and FIG. FIG.

  In the opened booklet in this example, as shown in FIG. 11, three intermediate sheets 230 a to 230 c having a shape smaller than that of the top sheet 210 and the back sheet 220 are sandwiched between the top sheet 210 and the back sheet 220. The top sheet 210, the back sheet 220, and the intermediate sheets 230 a to 230 c are configured such that one side thereof becomes a binding portion 202 and is bound by adhesion using an adhesive 241. Further, the top sheet 210 and the back sheet 220 are bonded together by an adhesive 242 at three periphery other than the binding portion 202.

  The top sheet 210 has a perforation 214 formed along the binding portion 202 and a perforation 213 formed along a region bonded to the back sheet 220 by the adhesive 242. And the outer side of the perforation 213 becomes the sticking part 211 adhere | attached on the back surface sheet 220, and the inner side of the perforation 213 becomes the spread part 212 opened around the binding part 202. In addition, in the surface sheet 210, one corner of the spread portion 212 serves as an opening start portion 215, and information for instructing to start opening the open booklet 201 is displayed.

  In the open booklet 201 configured as described above, the perforation 213 is broken from the opening start portion 215, and the perforation 214 is used as a folding portion to open the spread portion 212 around the binding portion 202. Thus, the information displayed on the intermediate sheets 230a to 230c can be browsed.

Japanese Patent No. 5515412 JP 2004-25536 A

  FIG. 12 is a diagram illustrating a state where the unsealed booklet 201 illustrated in FIG. 11 is being unsealed.

  As shown in FIG. 12A, the unsealed booklet 201 shown in FIG. 11 breaks the perforation 213 from the opening start portion 215, and uses the perforation 214 as a folding portion to spread the binding portion 202 as a center. It is opened by opening the part 212.

  When the perforation 213 is broken and the separation region between the spread portion 212 and the sticking portion 211 reaches the end portion of the perforation 213, as shown in FIG. The force continues to act in the direction of A in the figure where the perforation 213 extends.

  For this reason, as shown in FIG. 12C, the topsheet 210 may tear from the end portion of the perforation 213 to the extension line of the perforation 213, and may break to the binding portion 202 that should not be originally broken. There is.

  In this way, in an open booklet in which a plurality of sheets are bound by bonding with one side being a binding portion and opened around the binding portion, separation lines such as perforations are broken when being opened. When an external force such as the above is applied, there is a possibility that the portion that should not be originally broken at the binding portion may be broken.

  The present invention has been made in view of the problems of the conventional techniques as described above, and a plurality of sheets are bound by bonding with one side thereof being a binding portion, and are spread around the binding portion. An object of the present invention is to provide an open booklet that can make it difficult to break a portion that should not be originally broken at the binding portion when an external force is applied when the book is opened.

In order to achieve the above object, the present invention provides:
A plurality of sheets, an open booklet that is opened by being spread around the binding portion, with one side bound as a binding portion, and being bound,
Of the plurality of sheets, one of the two sheets exposed in an unopened state is
A sticking part bonded to the other sheet of the two sheets, in the vicinity of 3 other than the binding part,
It consists of a cut portion and a tie portion, and has one separation line formed along the sticking portion and having a joint portion with the binding portion as an end portion,
Among the cut portions, the cut portion constituting one of the end portions has an end portion closer to the joint portion among both ends of the cut portion, and an end portion farther from the joint portion than both ends of the cut portion. It is a direction regulation cut part which faced the direction of 90 degrees or less on the opposite side to the pasting part with respect to the cut part as a reference .

  In the present invention configured as described above, by separating the separation line formed on one of the two sheets exposed in an unopened state, the sticking part of the sheet Is bonded to the other sheet, and the region other than the sticking portion is separated from the sticking portion, so that the binding portion is opened as a center. Each of the separation lines has an end portion at the joint portion with the binding portion, but the cut portion constituting one of the termination portions among the cut portions constituting the separation line is an end portion on the joint portion side with the binding portion. However, since it is a direction-regulating cut portion that faces a direction of 90 degrees or less on the opposite side to the sticking portion with respect to the direction in which the end portion on the opposite side to the joint portion with the binding portion faces, When the region where the separation line is broken to reach the end of the sheet reaches its end, even if the force to break the separation line continues to be applied in the direction of opening the sheet, A portion that is dispersed in a direction different from the direction in which the pages are spread and is not supposed to be broken at the binding portion is hardly broken.

In addition, the plurality of sheets are bound by binding with one side thereof being a binding portion, and at least two of the plurality of sheets are separated into strips and stripped pieces other than the binding portions. At least a part of the region is configured to be peeled and bonded, and is an open booklet that is opened by being opened around the binding portion,
The sheet that becomes the peeling piece is configured as a spread portion other than the binding portion, and the spread portion is peeled from the sheet that becomes the peeled piece and is configured to be spread around the binding portion, and the spread portion and It extends from one end side that intersects the boundary line that constitutes the boundary , of the end side of the sheet that becomes the separation piece, to the boundary with the binding portion, and the end portion is in a direction away from the one side of the one end side. And a direction-regulating cut portion that faces a direction of 90 degrees or less.

  In the present invention configured as described above, the two sheets bonded in a peelable manner are separated into a peeling piece and a piece to be peeled off, and the sheet is opened with the binding portion as the center. become. At that time, the sheet that becomes the peeling piece extends from one end side that intersects the boundary of the sheet that becomes the peeling piece, to the boundary between the spread portion and the binding portion that is peeled from the sheet that becomes the peeling piece, and the end portion thereof, Since it has a direction regulation cut portion that faces a direction of 90 degrees or less with respect to the direction away from one side that becomes the binding portion of the one end side, the region where the sheet that becomes the peeling piece is peeled from the sheet that becomes the peeling piece, When it reaches the boundary between the spread part and the binding part of the peeling piece, the force to peel the sheet that becomes the peeling piece from the sheet that becomes the peeling piece in order to spread the sheet continues in the direction to open the sheet. Even if added, the force is distributed in a direction different from the direction in which the sheet is opened, and the portion that should not be originally broken at the binding portion is hardly broken.

  In addition, if the direction regulation cut portion is rounded, when the direction regulation cut portion is formed, the breaking force for forming the direction regulation cut portion is uniformly applied to the entire direction regulation cut portion, resulting in uneven formation. In addition, the force that breaks the separation line or peels off the sheet after opening the sheet is more likely to face the end of the direction regulating cut part.

  Also, if the end of the direction regulation cut portion is oriented in a direction perpendicular to the direction in which the binding portion extends, the force to break the separation line or peel the sheet after opening the sheet, The direction is opposite to the binding portion, and the portion that should not be originally broken at the binding portion is more difficult to break.

  According to the present invention, when the region where the separation line is broken in order to open the sheet reaches the end portion having the direction regulation cut portion, the force for breaking the separation line is in the direction of opening the sheet. Even if the force continues to be applied, the force is distributed in a direction different from the direction in which the sheet is opened, thereby making it difficult to break the portion that should not be broken at the binding portion.

  In addition, when the area where the sheet that becomes the peeling piece is peeled from the sheet that becomes the peeling piece reaches the boundary between the spread portion and the binding portion of the peeling piece, the sheet that becomes the peeling piece is covered to spread the sheet. Even if the force to peel from the sheet that becomes the peeling piece continues to be applied in the direction of opening the sheet, the force is distributed in a direction different from the direction of opening the sheet, so that the binding portion Thus, it is possible to make it difficult to break a portion that should not be broken.

  Further, in the case where the direction regulation cut portion is rounded, when the direction regulation cut portion is formed, the breaking force for forming the direction regulation cut portion is uniformly applied to the entire direction regulation cut portion, It is possible to make the formation unevenness less likely to occur, and after opening the sheet, it is possible to make the force to break the separation line or peel the sheet easily toward the end of the direction regulating cut part. .

  In addition, in the case where the end of the direction regulating cut portion is oriented in a direction orthogonal to the direction in which the binding portion extends, the force for breaking the separation line or peeling the sheet after opening the sheet. However, it will go in the direction opposite to the binding portion, and the portion that should not be originally broken at the binding portion will be more difficult to break.

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

(First embodiment)
1A and 1B are diagrams showing a first embodiment of an unsealed booklet according to the present invention, in which FIG. 1A is a front view, FIG. 1B is a cross-sectional view taken along line AA ′ shown in FIG. It is a figure which shows the state opened. FIG. 2 is a view showing a laminated structure of the unsealed booklet 1 shown in FIG.

  As shown in FIG. 1, the open booklet in this embodiment has three intermediate sheets 30 a to 30 c sandwiched between the top sheet 10 and the back sheet 20, and these top sheet 10, back sheet 20, and intermediate sheet 30 a to 30. 30c is configured such that one side thereof becomes a binding portion 2 and is bound by adhesion using an adhesive 41. In addition, the top sheet 10 and the back sheet 20 that are exposed in an unopened state are bonded together by an adhesive 42 around three areas other than the binding portion 2.

  The top sheet 10 and the back sheet 20 have the same shape, and are overlapped so that the four sides overlap each other, whereby each side becomes the binding portion 2 and each of the three periphery other than the binding portion 2 is bonded. Bonded by the agent 42.

  The top sheet 10 has a perforation 14 formed along the binding portion 2, and a perforation 13 forming a separation line along a region bonded to the back sheet 20 by the adhesive 42 in a U-shape. ing. The perforation 13 has a configuration in which cut portions 13a and tie portions 13b are alternately arranged. And the outer side of the perforation 13 becomes the sticking part 11 adhere | attached on the back surface sheet 20, and the inner side of the perforation 13 becomes the spread part 12 opened apart centering on the binding part 2. FIG. Further, on the top sheet 10, one corner on the opposite side of the spread portion 12 from the binding portion 2 serves as an opening start portion 15, and information for instructing the opening of the opened booklet 1 is displayed.

  The intermediate sheets 30a to 30c have the same shape and are sandwiched between the top sheet 10 and the back sheet 20 so that the top sheet 10 and the back sheet 20 and the binding portion 2 are shared. Furthermore, it has a size and shape that face only the spread part 12 and does not face the sticking part 11. Accordingly, the intermediate sheets 30a to 30c are bonded to the other intermediate sheet, the top sheet 10, and the back sheet 20 only by the adhesive 41 in the binding portion 2, and depending on the adhesive 42, the top sheet 10 and the back sheet 20 are bonded. And is not glued. Thereby, the top sheet 10 and the back sheet 20 are directly bonded to each other by the adhesive 42 at the sticking portion 11 although the intermediate sheets 30a to 30c are interposed therebetween.

  Here, the relationship between the perforation 13 and the binding part 2 in the open booklet 1 configured as described above will be described in detail.

  FIG. 3 is a view for explaining the relationship between the perforation 13 and the binding portion 2 in the opened booklet 1 shown in FIGS. 1 and 2, and (a) is a form in which the U-shaped cut portion 13c is not employed. The whole figure which shows the outline of the relationship between the perforation 13 in this, and the binding part 2, (b) is a figure which shows the structure of the cut part in the junction part 3 shown to (a), (c) is the U-shaped cut part 13c. It is a figure which shows the structure of the junction part 3 in the form by which was adopted.

  As shown in FIG. 3A, the perforations 13 are formed along the periphery of the top sheet 10 bonded to the back sheet 20 with the adhesive 42 in the top sheet 10, and the joints 3 to the binding section 2 are respectively formed. It has a termination.

  As shown in FIG. 3B, the cut portion 13 a constituting the perforation 13 has an end portion 16 a on the joint portion 3 side and an end portion 16 b on the opposite side to the joint portion 3. Yes.

  As shown in FIG. 3C, the perforation 13 formed in such a manner as to have a relationship with the binding portion 2 constitutes a terminal portion in the opened booklet 1 shown in FIGS. The cut portion is a direction restricting cut portion for restricting the breaking direction of the perforation 13, and the shape thereof is a U-shaped U-shaped cut portion 13c. This direction regulation cut part is formed by changing the shape of the last cut part of the separation line cut off when the spread part 12 is separated from the surface sheet 10. The U-shaped cut portion 13 c extends from the side opposite to the binding portion 2 toward the binding portion 2, is rounded, returns to the side opposite to the binding portion 2, and is an end of the binding portion 2 side with the binding portion 2. The part 16a faces the side opposite to the binding part 2. That is, the U-shaped cut portion 13c is connected to the binding portion 2 of the top sheet 10, the back sheet 20, and the intermediate sheets 30a to 30c in a direction in which the end portion 16a on the side of the joint portion 3 with the binding portion 2 is away from the binding portion 2. It faces in the direction orthogonal to the direction in which one side extends. Thereby, as for the U-shaped cut part 13c, the direction which the edge part 16a by the side of the junction part 3 with the binding part 2 goes to the direction where the edge part 16b on the opposite side to the junction part 3 with the binding part 2 goes is directed. The angle is 90 degrees or less on the side opposite to the sticking part 11. The perforation 14 is provided to make a crease when the spread part 12 is opened, but a fold line such as a muscle push may be used instead of the perforation 14.

  Below, the usage method of the open booklet 1 comprised as mentioned above is demonstrated.

  FIG. 4 is a diagram for explaining a method of using the opened booklet 1 shown in FIGS. 1 and 2.

  When opening the unsealed booklet 1 shown in FIGS. 1 and 2, as shown in FIG. 4 (a), by pulling up the opening start portion 15 or pulling it in the diagonal direction of the spread portion 12, The perforation 13 is broken from the opening start portion 15. Since the perforation 13 has a configuration in which the cut portions 13a and the tie portions 13b are alternately arranged, the perforation 13 is broken by breaking the tie portion 13b and connecting the cut portions 13a. At this time, the sticking part 11 of the top sheet 10 remains adhered to the back sheet 20, while the spread part 12 is separated from the sticking part 11 as the spread part 12 is spread. .

  When all the perforations 13 are broken and the separation region between the spread portion 12 and the sticking portion 11 reaches the end portion of the perforation 13, as shown in FIG. By using the binding portion 2 as a center, the spread portion 12 is completely opened so that the information displayed on the surface of the intermediate sheet 30a facing the top sheet 10 can be browsed. At that time, information displayed on the surface of the top sheet 10 facing the intermediate sheet 30a can also be browsed.

  Further, since the intermediate sheets 30a to 30c are bonded to each other only by the adhesive 41 in the binding portion 2, as shown in FIG. 4C, after opening the surface sheet 10, the binding portion 2 is the center. By opening the intermediate sheet 30a, the information displayed on the surface of the intermediate sheet 30a facing the intermediate sheet 30b and the surface of the intermediate sheet 30b facing the intermediate sheet 30a can be viewed. Further, by opening the intermediate sheets 30a and 30b around the binding portion 2, the information displayed on the surface of the intermediate sheet 30b facing the intermediate sheet 30c and the surface facing the intermediate sheet 30b of the intermediate sheet 30c can be browsed. It becomes. Furthermore, by opening the intermediate sheets 30a to 30c around the binding portion 2, information displayed on the surface facing the back sheet 20 of the intermediate sheet 30c and the surface facing the intermediate sheet 30c of the back sheet 20 can be viewed. Become.

  Here, the effect by the U-shaped cut part 13c is demonstrated.

  FIG. 5 is a diagram for explaining the effect of the U-shaped cut portion 13a in the opened booklet 1 shown in FIGS.

  When opening the unsealed booklet 1 shown in FIGS. 1 and 2, as described above, the perforation 13 is broken from the opening start portion 15, and as shown in FIG. Using the folded portion, the spread portion 12 is spread around the binding portion 2.

  When the perforation 13 breaks and the separation region between the spread portion 12 and the sticking portion 11 reaches the end portion of the perforation 13 at the joint portion with the binding portion 2, the cut portion constituting the perforation 13 A cut portion constituting a straight end portion including the opening start portion 15 of the perforation 13 of 13a extends from the side opposite to the binding portion 2 toward the binding portion 2, and is rounded to the binding portion 2. 5a, the end portion 16a on the joint portion side with the binding portion 2 is a U-shaped U-shaped cut portion 13c facing the opposite side to the binding portion 2. As shown in b), even if the force for breaking the perforation 13 continues to be applied in the direction in which the surface sheet 10 is opened, the direction A in the figure opposite to the direction in which the surface sheet 10 is opened. Will be distributed.

  Thereby, as shown in FIG.5 (c), the part which should not be fractured originally in the binding part 2 can be made hard to be fractured.

  In the present embodiment, of the two end portions of the perforation 13, only the cut portion constituting the straight end portion including the opening start portion 15 of the perforation 13 is the U-shaped cut portion 13c. This is because when the spread portion 12 is opened by breaking the perforation 13 from the opening start portion 15, the separation region between the spread portion 12 and the sticking portion 11 is the two end portions of the perforation 13. Of the perforation 13 on the straight line including the opening start portion 15, the perforation 13 is formed on the end of the cut portion constituting the end portion on the side of the joint portion with the binding portion 2. This is because a force is applied to break the surface. In other words, the opening start portion 15 may be set at a corner on a straight line including the U-shaped cut portion 13c of the perforation 13.

  Further, in this embodiment, the direction regulating cut portion extends from the side opposite to the binding portion 2 toward the binding portion 2, is rounded, returns to the side opposite to the binding portion 2, and is connected to the binding portion 2. The U-shaped U-shaped cut portion 13c whose end portion on the joint portion side faces the side opposite to the binding portion 2 has been described as an example, but the direction-regulating cut portion is a joint portion with the binding portion 2. It suffices if the end on the side faces the direction of 90 degrees or less on the side opposite to the sticking portion 11 with respect to the direction in which the end on the side opposite to the joining portion faces.

  FIG. 6 is a diagram illustrating another configuration example of the direction regulation cut portion.

  As shown in FIG. 6A, the direction regulation cut portion may extend from the opposite side to the binding portion 302 toward the binding portion 302 and draw an arc to be connected to the perforation 314. .

  Further, as shown in FIG. 6B, it extends from the side opposite to the binding unit 2 toward the binding unit 2, returns to the side opposite to the binding unit 402 without being rounded, and is connected to the binding unit 402. The end portion on the joint portion side may face the side opposite to the binding portion 402.

  Further, as shown in FIG. 6C, it may extend from the opposite side to the binding portion 502 toward the binding portion 502, bend at a right angle, and be connected to the perforation 514.

  However, if the direction regulation cut portion has a rounded shape, the direction regulation cut portion is formed through the top sheet 10, and therefore, when the direction regulation cut portion is formed, the direction regulation cut portion is formed. After the breaking force for forming the portion is uniformly applied to the entire direction regulating cut portion, the surface sheet 10 can be surely penetrated, formation unevenness can be hardly generated, and the spread portion 12 is opened. In this case, when a force for breaking the perforation 13 is applied in a direction in which the top sheet 10 is widened, the force can be easily directed toward the end of the direction regulating cut portion. Moreover, the edge part of a direction control cut part becomes the binding part 2 of the surface sheet 10, the back sheet 20, and the intermediate | middle sheets 30a-30c in the direction away from the binding part 2, like the U-shaped cut part 13c of this form. If one side is oriented in a direction orthogonal to the extending direction, the force to break the perforation 13 after the spread portion 12 is spread is applied in the direction in which the top sheet 10 is widened. Will go in the direction opposite to the binding portion 2, and the portion that should not be originally broken at the binding portion 2 is more difficult to break. In particular, in the case where the perforation 14 is provided to make a crease along the binding portion 2 when the spread portion 12 is opened as in the open booklet 1 of the present embodiment, after the spread portion 12 is opened. The top sheet 10 may be broken along the perforation 14, but the top sheet in the direction in which the end portion of the direction regulating cut portion is separated from the binding portion 2 as in the U-shaped cut portion 13 c. 10. If the back sheet 20 and the intermediate sheets 30a to 30c are oriented in a direction perpendicular to the extending direction of one side of the intermediate sheet 30a to 30c, the force to break the perforation 13 after opening the spread part 12 is bound. It will go to the direction opposite to the part 2, and it will become difficult to fracture | rupture the surface sheet 10 along the perforation 14.

(Second Embodiment)
FIG. 7 is a view showing a second embodiment of an unsealed booklet according to the present invention, where (a) is a front view, (b) is a cross-sectional view along AA ′ shown in (a), and (c) is a cross-sectional view. It is a figure which shows the state opened. FIG. 8 is a view showing a laminated structure of the open booklet 101 shown in FIG.

  As shown in FIG. 7, the unsealed booklet in this embodiment is formed by laminating a front sheet 110, an intermediate sheet 130, and a back sheet 120 so that three sides of each of them overlap each other, and one side thereof becomes a binding portion 102 and is bonded. It is formed by binding using an adhesive 141. The top sheet 110, the intermediate sheet 130, and the back sheet 120 have different widths in the direction perpendicular to the binding portion 102, the top sheet 110 has the smallest width, and the back sheet 120 has the widest width. Accordingly, when the intermediate sheet 130 is laminated on the back sheet 120 and the front sheet 110 is laminated on the intermediate sheet 130 so that the sides that become the binding portion 102 overlap, the intermediate sheet 130 is intermediate on the side opposite to the binding portion 102. Part of the sheet 130 and the back sheet 120 has a stepped surface. Further, the three periphery other than the binding portion 102 of the surface sheet 110 is detachably bonded to the intermediate sheet 130 by a peelable adhesive 143 that can be peeled off after bonding, and the three periphery other than the binding portion 102 of the intermediate sheet 130 is The peelable adhesive 143 is detachably bonded to the back sheet 120. Thereby, the top sheet 110 and the intermediate sheet 130 are detachably bonded at a part other than the binding part 102, and the intermediate sheet 130 and the back sheet 120 are peeled off at a part of the area other than the binding part 102. It is possible to adhere. And when the surface sheet 110 peels from the intermediate sheet 130, while the surface sheet 110 becomes a peeling piece, the intermediate sheet 130 becomes a piece to be peeled. Further, when the intermediate sheet 130 is peeled from the back sheet 120, the intermediate sheet 130 becomes a peeled piece and the back sheet 120 becomes a peeled piece. Further, when the top sheet 110 is a peeling piece, the area other than the binding part 102 of the top sheet 110 becomes the spread part 112, and when the intermediate sheet 130 is the peeling piece, the area other than the binding part 102 of the intermediate sheet 130 Becomes a spread part 132 (see FIG. 9). The top sheet 110 and the intermediate sheet 130, and the intermediate sheet 130 and the back sheet 120 may be detachably bonded to the entire surface other than the binding portion 102.

  The surface sheet 110 is formed with a direction regulating cut portion for regulating the direction when the surface sheet 110 is peeled from the intermediate sheet 130 at the boundary between the spread portion 112 and the binding portion 102, and the shape thereof is U A U-shaped cut portion 113 having a letter shape is formed. This direction regulation cut part is formed by changing the shape of the boundary with the binding part 102 when the top sheet 110 is peeled from the intermediate sheet 130. The U-shaped cut portion 113 is an edge on the side including the opening start portion 115 of the two edges that intersect the boundary with the binding portion 102 of the topsheet 110 at the boundary between the spread portion 112 and the binding portion 102. First, it extends in a direction approaching the binding portion 102, and then is rounded and extends to the opposite side of the binding portion 102, and its end portion faces the opposite side of the binding portion 102. That is, the U-shaped cut portion 13 c is oriented in a direction orthogonal to the direction in which one side that becomes the binding portion 102 of the topsheet 110 and the intermediate sheet 130 extends in a direction away from the binding portion 102. In addition, on the top sheet 110, one corner on the side opposite to the binding portion 102 serves as an opening start portion 115, and information for instructing the opening of the opening booklet 101 is displayed. Thereby, the U-shaped cut portion 113c extends from one end side intersecting the boundary of the topsheet 110 to the boundary between the spread portion 112 and the binding portion 102, and the end portion is bound to the topsheet 110 of the one end side. The direction is 90 degrees or less with respect to the direction away from one side to be the portion 102.

  Below, the usage method of the open booklet 101 comprised as mentioned above is demonstrated.

  FIG. 9 is a diagram for explaining how to use the opened booklet 101 shown in FIGS. 7 and 8.

  When opening the unsealed booklet 101 shown in FIG. 7 and FIG. 8, as shown in FIG. 9 (a), by pulling up the opening start portion 115 upward or pulling it in the diagonal direction of the topsheet 110, The top sheet 110 is peeled from the intermediate sheet 130. Since the three periphery other than the binding portion 102 of the surface sheet 110 is detachably bonded to the intermediate sheet 130 by the peelable adhesive 143 that can be peeled after bonding, in the spread portion 112 other than the binding portion 102, The intermediate sheet 130 can be peeled off.

  When the area where the topsheet 110 is peeled from the intermediate sheet 130 reaches the boundary between the spread portion 112 and the binding portion 102, the spread portion 112 of the topsheet 110 is completely removed as shown in FIG. 9B. It is opened by peeling off from the intermediate sheet 130, and information displayed on the surface of the top sheet 110 facing the intermediate sheet 130 and the surface facing the top sheet 110 of the intermediate sheet 130 can be browsed.

  Further, since the intermediate sheet 130 has three peripheral portions other than the binding portion 102 detachably bonded to the back sheet 120 by a peelable adhesive 143 that can be peeled after bonding, as shown in FIG. 9C. Further, after the front sheet 110 is opened, the spread portion 132 of the intermediate sheet 130 is peeled off from the back sheet 120, so that the intermediate sheet 130 can be opened with the binding portion 102 as the center. Information displayed on the surface facing the sheet 120 and the surface facing the intermediate sheet 130 of the back sheet 120 can be browsed.

  Here, the effect of the U-shaped cut portion 113c will be described.

  FIG. 10 is a diagram for explaining the effect of the U-shaped cut portion 113a in the unsealed booklet 101 shown in FIGS.

  When opening the unsealed booklet 101 shown in FIGS. 7 and 8, as described above, the spread portion 112 of the topsheet 110 is peeled off from the intermediate sheet 130 using the unsealing start portion 115 as a peeling start end. As shown to (a), the surface sheet 110 is opened apart centering on the binding part 102. As shown in FIG.

  When the spread portion 112 of the topsheet 110 is peeled off from the intermediate sheet 130 and the region where the topsheet 110 is peeled from the intermediate sheet 130 reaches the boundary between the spread portion 112 and the binding portion 102 of the topsheet 110, In the region serving as the boundary, of the two end sides of the topsheet 110 that intersects the boundary with the binding portion 102, first, the end side that includes the opening start portion 115 extends in the direction approaching the binding portion 102, and then As shown in FIG. 10B, a U-shaped cut portion 113 that is rounded and extends to the opposite side of the binding portion 102 and has an end facing the opposite side of the binding portion 102 is formed. In addition, even if a force for peeling off the topsheet 110 continues to be applied in the direction in which the topsheet 110 is opened, the force is in a direction in which the topsheet 110 is opened. It will be dispersed in the drawing direction A on the opposite side.

  Thereby, as shown in FIG.10 (c), the binding part 102 can be made hard to fracture | rupture.

  In the present embodiment, the U-shaped cut portion 113 extends from the end side on the side including the unsealing start portion 115 of the two end sides of the topsheet 110 that intersect the boundary between the spread portion 112 and the binding portion 102. ing. This is because when the topsheet 110 is peeled off from the opening start portion 115, the region where the topsheet 110 is peeled from the intermediate sheet 130 intersects the boundary between the spread portion 112 and the binding portion 102 of the topsheet 110. The boundary between the binding edge 102 at the two edges and the binding area 102 at the edge of the opening start section 115 is reached first by reaching the boundary with the binding area 102 at the edge including the opening start section 115. This is because a force for peeling the top sheet 110 from the intermediate sheet 130 is applied. In other words, the opening start portion 115 is formed at a corner portion on the end side including the U-shaped cut portion 113 among the two end portions of the top sheet 110 that intersect the boundary between the spread portion 112 and the binding portion 102. You just have to set it.

  Further, in this embodiment, as the direction regulation cut portion, at the boundary between the spread portion 112 and the binding portion 102 of the topsheet 110, the edge first extends from the edge of the topsheet 110 in the direction approaching the binding portion 102, and then rounded. The U-shaped cut portion 113 that extends to the opposite side of the binding portion 102 and whose end portion faces the opposite side of the binding portion 102 has been described as an example, but is shown in the first embodiment. Similarly to the case, it may extend from the edge of the top sheet 110 in a direction approaching the binding portion 102, and then go in a direction in which the binding portion 102 extends by drawing an arc. Very good configuration as no shape. In any case, the end of the direction regulation cut part is 90 degrees or less with respect to the direction away from one side of the top sheet 110 where the direction regulation cut part extends from the one side that becomes the binding part 102 of the top sheet 110. As long as it faces the direction, the above-described effects can be obtained. However, if the direction regulation cut portion is rounded, the direction regulation cut portion is formed through the top sheet 110. Therefore, when the direction regulation cut portion is formed, the direction regulation cut portion is formed. After the breaking force for forming the portion is uniformly applied to the entire direction regulating cut portion, the surface sheet 110 can be surely penetrated, formation unevenness can be hardly generated, and the surface sheet 110 is opened. In this case, when a force for peeling off the topsheet 110 is applied in a direction in which the topsheet 110 is widened, the force can easily be directed toward the end of the direction regulation cut portion. Further, in the direction in which the end portion of the direction regulation cut portion is away from the binding portion 102 as in the U-shaped cut portion 113 of this embodiment, one side that becomes the binding portion 102 of the top sheet 110, the intermediate sheet 130, and the back sheet 120 is If the surface sheet 110 is oriented in a direction orthogonal to the extending direction, if the force to peel off the surface sheet 110 is applied in the direction of opening the surface sheet 110 after the surface sheet 110 is opened, the force is bound. It will go to the direction opposite to the part 102, and the binding part 102 will become still more difficult to fracture | rupture.

  Also, in the intermediate sheet 130, if the U-shaped cut portion 113 is formed at the same position as the top sheet 110, the intermediate sheet 130 becomes a release piece, the back sheet 120 becomes a release piece, and the intermediate sheet 130 becomes When peeling from the back surface sheet 120, it is possible to avoid the binding portion 102 of the intermediate sheet 130 from being broken.

  Further, the number of intermediate sheets is not limited to two or three as described above.
