JP7620774B2 - Information holder - Google Patents

Description

The present invention relates to an information carrier consisting of a sheet piece on which appropriate information such as address information is displayed.

Conventionally, when a sender sends advertising information such as product introduction information to a recipient using a postcard or envelope as an information carrier, once the content of the advertising information has been confirmed by the recipient, even if the recipient has shown some interest in the product, the postcard or pamphlet is often left out of sight. Postcards and pamphlets left out in this way are often forgotten over time and discarded without the contents being checked again, which creates the problem that advertising by conventional mail cannot be expected to have a significant advertising effect.

For example, the information carrier in Patent Document 1 is made up of three or more sheet pieces connected via folding sections that are folded over at the folding sections, and the overlapping surfaces of the sheet pieces are releasably bonded together with an adhesive member, making it possible to display a large amount of advertising information. In the unfolded state, the engaging sections formed on the sheet pieces located at both the left and right ends can be engaged with each other to transform the carrier into a self-supporting cylindrical shape. In this way, the carrier can be transformed into a three-dimensional cylindrical shape and placed upright on a table or the like, allowing the advertising information displayed on the unfolded surface and the outer peripheral surface of the tube to be seen by multiple people.

Japanese Patent No. 5268534 (page 3, figure 4)

The adhesive material that bonds the overlapping surfaces of the sheet pieces in the information carrier of Patent Document 1 is applied over the entire overlapping surfaces of the sheet pieces or to the periphery of the sheet pieces including the engagement portion, effectively preventing accidental peeling or damage when the information carrier is mailed. However, because the adhesive material is also applied to the engagement portion, when peeling the sheet pieces that are attached with adhesive from each other, there is a possibility that the vicinity of the engagement portion may be damaged depending on the peeling direction.

The present invention was made with an eye on these problems, and aims to provide an information holder that can be securely engaged to form a cylindrical shape.

In order to solve the above problems, the information carrier of the present invention comprises:
An information carrier is formed by folding three or more sheets connected via a folding section, each sheet displaying appropriate information such as address information, and overlapping the overlapping surfaces of the sheets at the folding section, and releasably adhering the overlapping surfaces to each other at an adhesive section, and by engaging the engaging sections at both left and right ends of the information carrier in an unfolded state, the information carrier can be formed into a self-supporting cylindrical shape,
The sheet piece on one end side, which is positioned at the outermost side when folded over, is characterized in that it has a non-adhesive portion at the engagement portion that engages with the sheet piece on the other end side, and has the adhesive portion at another specified location.
According to this feature, when the sheet piece at one end located at the outermost position is peeled off from the sheet piece to which it is adhered, the stress applied to the engagement portion can be reduced, and damage during peeling can be effectively prevented. As a result, the engagement portion of the sheet piece at one end can be securely engaged with the sheet piece at the other end to form a cylindrical shape.

the sheet piece at the one end side has a protruding piece constituting the engaging portion, and the non-adhesive portion is formed on the entire surface of the protruding piece,
In the folded state, the protruding piece is characterized in that the non-adhered portion overlaps the sheet piece to which the sheet piece on the one end side is adhered.
According to this feature, since the entire surface of the protruding piece is a non-adhesive portion, the stress generated when the sheet pieces are peeled away from each other does not act on the protruding piece, and the protruding piece is not damaged. In addition, since no adhesive portion is formed, the frictional resistance between the protruding pieces during engagement and release of the engagement state is small, and the engagement and release of the engagement state can be performed smoothly. Furthermore, since the protruding piece is prevented from protruding outward from the sheet piece to which the sheet piece on one end side is adhered when the sheets are folded over, unintended peeling of the sheet pieces from each other and damage to the protruding piece are unlikely to occur due to the protruding piece getting caught, etc.

The protruding piece is characterized in that it is formed symmetrically between the upper end side and the lower end side of the information holder.
According to this feature, not only is the posture well-balanced when the cylindrical shape is configured and erected, but the structural strength in the cylindrical configuration is also high.

The sheet piece at one end has an adhesive portion provided on the overlapping surface thereof, the adhesive portion extending linearly in the vertical direction and laterally inward from the protruding piece.
According to this feature, it is possible to easily form an adhesive portion that can effectively prevent the information carrier from being accidentally peeled off or damaged during delivery.

The following describes an embodiment of the information holder according to the present invention.

The information holder according to the embodiment will be described with reference to Figs. 1 to 7. In the following description, the top, bottom, left and right of the information holder as viewed from the front of Fig. 1 will be referred to as the top, bottom, left and right.

As shown in FIG. 1, the information carrier 1 is used as direct mail containing the sender's company name, the advertising status of products handled, etc., and is delivered to the destination folded into an envelope in the sent state. Note that the information carrier 1 in the sent state may also be folded into a postcard. Furthermore, it is not limited to direct mail, and the contents written and the purpose of use may be changed as appropriate.

A recipient who receives the information carrier 1 in the sent state can peel the overlapping surfaces of the sheet pieces 11 to 14 described below together to unfold it as shown in FIG. 2, and can confirm the advertising information written on it. In addition, by assembling the information carrier 1 in the unfolded state, it can be assembled as shown in FIG. 3 and placed upright on a desk or shelf. The configuration of the information carrier 1 will be explained below using the unfolded state as an example.

As shown in FIG. 2(a), the information carrier 1 in the unfolded state is a paper medium made of a long, horizontally long continuous length of coated paper, and is formed by folding portions A1-C1, indicated by the two-dot chain lines, which are folded to guide the folding of the information carrier 1 on a rectangular sheet of paper of approximately the same size as the information carrier 1, and by providing engagement portions 11S, 14S at both the left and right ends by cutting out the paper.

Folded portions A1 to C1 may be perforated at a specified interval, half slit, or creasing, and may be modified as appropriate depending on the application. Information carrier 1 is not limited to a paper medium made of coated paper, and may be a laminated paper medium, high-quality paper, or a resin sheet, and may be modified as appropriate.

The information holder 1 comprises four sheet pieces 11-14 divided by folds A1-C1. From the left side of the page in FIG. 2(a), the sheet pieces 11-14 are the first sheet piece 11, the second sheet piece 12, the third sheet piece 13, and the fourth sheet piece 14, on which the address, name, etc. of the recipient are written. Note that each sheet piece is not limited to being formed by dividing a single sheet medium by folds A1-C1, but may also be formed by gluing together a number of independent sheet pieces.

In addition, in this description, the information carrier 1 in an unfolded state is used as a reference, and as shown in FIG. 2(a), of the sheets 11-14, the side of the first sheet 11 on which the address, name, etc. of the recipient is written is referred to as the front side 11F-14F, and as shown in FIG. 2(b), the side opposite the front side 11F-14F is referred to as the back side 11R-14R.

The first sheet piece 11 has an engagement portion 11S at its left end that extends parallel to the fold A1, and the engagement portion 11S has protruding pieces 2 and 3 formed at its upper and lower ends.

The protruding piece 2 has a side edge 2a that extends downward generally perpendicular to the upper edge 11U of the first sheet piece 11, and a convex end edge 2b that is continuous with the lower end of the side edge 2a and protrudes downward in an arrowhead shape. The protruding piece 3 has a starting edge 3a that is continuous with the lower edge 11D of the first sheet piece 11 and extends diagonally upward, a side edge 3b that is continuous with the upper end of the starting edge 3a and extends upward along generally the same straight line as the side edge 2a, and a convex end edge 3c that is continuous with the upper end of the side edge 3b and protrudes upward in an arrowhead shape.

The engaging portion 11S also has a side edge 11a that extends parallel to the side edges 2a, 3b of the protruding pieces 2, 3 and is continuous with the convex end edges 2b, 3c of the protruding pieces 2, 3. As a result, a slit 5 is formed between the convex end edge 2b and the side edge 11a of the protruding piece 2, and a slit 6 is formed between the convex end edge 3c and the side edge 11a of the protruding piece 3.

The fourth sheet piece 14 has an engagement portion 14S at its right end that extends parallel to the fold C1, and the engagement portion 14S has a protruding piece 4 formed in its center.

The protruding piece 4 has a side edge 4a that extends parallel to the folded portion C1 and the side edges 2a, 3b of the protruding pieces 2, 3, a convex end edge 4b that is continuous with the upper end of the side edge 4a and protrudes upward in an arrowhead shape, and a convex end edge 4c that is continuous with the lower end of the side edge 4a and protrudes downward in an arrowhead shape.

The engaging portion 14S is formed with a side edge 14a that extends downwardly and generally perpendicular to the upper end edge 14U of the fourth sheet piece 14 and continues to the convex end edge 4b, and a side edge 14b that extends upwardly and generally perpendicular to the lower end edge 14D of the fourth sheet piece 14 and continues to the convex end edge 4c. As a result, a slit 7 is formed between the convex end edge 4b and the side edge 14a of the protruding piece 4, and a slit 8 is formed between the convex end edge 4c and the side edge 14b of the protruding piece 4.

Next, the procedure for assembling the information holder 1 from the unfolded state to the assembled state will be described with reference to Figures 2 and 3.

First, referring to FIG. 2, the information carrier 1 in an unfolded state is folded along each of the folds A1 to C1 so that the surfaces 11F to 14F of each of the sheet pieces 11 to 14 are on the inside.

Next, engaging portions 11S and 14S are engaged with each other. More specifically, protruding piece 2 and protruding piece 4 are engaged through slits 5 and 7, and protruding piece 3 and protruding piece 4 are engaged through slits 6 and 8, so that the assembly state is a cylindrical body with a rectangular cross section as shown in FIG. 3.

When assembling the unfolded state into the assembled state, the back surfaces 11R-14R of the sheet pieces 11-14 may be folded inward, and then the engaging portions 11S, 14S may be engaged with each other.

Next, the procedure for folding the information carrier 1 from the unfolded state to the delivery state using a machine such as a folding machine (not shown) will be described with reference to Figures 4 to 6.

As shown in FIG. 4(a), first, with the back surfaces 11R-14R of each sheet piece 11-14 facing forward, the top edge 11U-14U of the information carrier 1, the side edges 2a-3b of the protruding pieces 2-3, the bottom edge 11D-14D of the information carrier 1, and the side edge 4a of the protruding piece 4 are abutted against flat guides or the like in a machine such as a folding machine (not shown), and the information carrier 1 is set in the machine.

Next, as shown in FIG. 4(b), adhesive is applied in a straight band on the back surfaces 11R-13R along the upper edges 11U-13U excluding the protruding piece 2 to form an attachment portion 9U, and adhesive is applied in a straight band along the lower edges 11D-13D excluding the protruding piece 3 to form an attachment portion 9D. This adhesive has the property that after being applied between the objects, the objects are bonded together by applying a pressure of a predetermined level or more, such as by folding the objects together around each fold.

Next, the back surface 14R of the fourth sheet piece 14 is folded and pressed against the back surface 13R of the third sheet piece 13, using the fold C1 as a base point, and the back surfaces 14R and 13R are adhered to each other by the adhesive parts 9U and 9D, as shown in FIG. 5(a). In this state, the protruding piece 4 is separated from the adhesive parts 9U and 9D.

The front surface 14F of the fourth sheet piece 14 is folded and pressed against the back surface 12R of the second sheet piece 12, using the folding portion B1 as a base point, and the front surface 14F and the back surface 12R are adhered to each other by the adhesion portions 9U and 9D, as shown in FIG. 5(b). As a result, the entire back surface and the entire front surface of the protruding piece 4 become non-adhesive portions 4F and 4R that are not adhered to the second and third sheet pieces 12 and 13.

Here, as shown in FIG. 4(a), the width dimension L4 of the fourth sheet piece 14 (the dimension between the side edge 4a of the protruding piece 4 and the folded portion C1) is shorter than the width dimension L3 of the third sheet piece 13 (the dimension between the folded portion C1 and the folded portion B1), and the width dimension L3 of the third sheet piece 13 is shorter than the width dimension L2 of the second sheet piece 12 (the dimension between the folded portion B1 and the folded portion A1) (L4<L3<L2). This prevents the protruding piece 4 from being folded along the folded portion B1 when the front surface 14F and the back surface 12R are bonded together.

Then, as shown in FIG. 6(a), adhesive is applied in a straight strip shape to the back surface 11R of the engagement portion 11S, inside the protruding pieces 2 and 3 (toward the folded portion A1), along the side edge 11a parallel to the folded portion A1, to provide the attachment portion 9S.

Then, starting from the fold A1, the back surface 11R of the first sheet piece 11 is folded and pressed against the front surface 13F of the third sheet piece 13, and as shown in FIG. 6(b), the back surface 11R and the back surface 13R are adhered to each other by the adhesive portions 9U, 9D, and 9S. In this way, the entire back surfaces of the protruding pieces 2 and 3 are non-adhesive portions 2R and 3R that are not adhered to the third sheet piece 13. In addition, the adhesive portions 9U, 9D, and 9S provided along the upper end edges 11U-13U, lower end edges 11D-13D, and side end edges 11a on the back surface 11R of the first sheet piece 11, which are located on the inside of the protruding pieces 2 and 3, are adhesive portions provided at other predetermined locations of the present invention.

In this way, the surface 11F of the first sheet piece 11, on which the address, name, etc. of the recipient is written, is positioned at the outermost side (front), and the sheet can be placed in a sent state. Therefore, the first sheet piece 11 is the sheet piece at one end side that is positioned at the outermost side in the present invention, and the fourth sheet piece having an engagement portion 14S that engages with the engagement portion 11S of the first sheet piece 11 in the assembled state is the sheet piece at the other end side in the present invention.

Referring to FIG. 4, the width dimension L2 of the second sheet piece 12 is approximately the same as the width dimension L1 of the first sheet piece 11 (the dimension between the folded portion A1 and the side edges 2a, 3b of the protruding pieces 2, 3) (L2=L1). This allows the side edges 2a, 3b of the protruding pieces 2, 3 to be arranged in approximately the same straight line as the folded portion B1 in the sent state, resulting in a good aesthetic appearance. In addition, since the protruding pieces 2, 3 are prevented from protruding outward beyond the second sheet piece 12 in the folded state, unintended peeling of the sheet pieces and damage to the protruding pieces 2, 3 due to the protruding pieces 2, 3 getting caught are unlikely to occur.

Next, the procedure for expanding the information holder 1 from the sending state to the expanded state will be described with reference to Figures 4 to 6.

First, as shown in Fig. 6(a), the first and third sheet pieces 11, 13 are peeled off. To start this peeling, as shown in Fig. 6(b), the corner of the third sheet piece 13 is exposed by the starting edge 3a formed on the protruding piece 3, and as shown in Fig. 6(a), the entire back surface of the protruding piece 3 is the non-adhesive portion 2R, 3R, making it easy to pinch a finger in the gap between the protruding piece 3 and the third sheet piece 13, so that the first and third sheet pieces 11, 13 can be easily peeled off.

The protruding piece 3 may not have a starting edge 3a. Even in this configuration, the first and third sheet pieces 11 and 13 can be easily peeled off because, as described above, none of the adhesive portions 9U, 9D, and 9S are formed on the protruding piece 3.

In addition, the adhesive portions 9U, 9D, 9S are formed linearly along the upper edge 11U-13U, lower edge 11D-13D, and folded portion A1 of the information carrier 1, inside the protruding pieces 2, 3. Compared to a configuration in which adhesive portions are provided on the entire overlapping surfaces of the first and third sheet pieces 11, 13, the area of the adhesive portions is narrow, so the resistance generated during peeling is small, and the first sheet piece 11 and the third sheet piece 13 can be peeled off from each other along the formation direction of the adhesive portions 9U, 9D, 9S, so the first and third sheet pieces 11, 13 can be easily peeled off.

Next, as shown in Fig. 5(a), the second and fourth sheet pieces 12 and 14 are peeled off. At this time, referring to Fig. 5(b), the width dimension L3 of the third sheet piece 13 is shorter than the width dimension L2 of the second sheet piece 12 (L3<L2), and the width dimension L4 of the fourth sheet piece 14 is shorter than the width dimension L3 of the third sheet piece 13 (L4<L3). Since the sheets are adhered only at the adhesive portions 9U and 9D, it is easy to insert a finger through the gap between the folded portion C1 and the back surface 12R, and therefore the second and fourth sheet pieces 12 and 14 can be peeled off easily.

Then, as shown in Fig. 4(b), the third and fourth sheet pieces 13, 14 can be peeled off to open the sheet. At this time, referring to Fig. 5(a), the width dimension L4 of the fourth sheet piece 14 is shorter than the width dimension L3 of the third sheet piece 13 (L4<L3), and since it is adhered only at the adhesive portions 9U, 9D, it is easy to insert a finger through the gap between the protruding piece 4 and the back surface 13R, so that the third and fourth sheet pieces 13, 14 can be peeled off easily.

In addition, when the third and fourth sheet pieces 13, 14 are adhered, the protruding piece 4 is separated from the adhesive portions 9U, 9D, and the entire front and back surfaces of the protruding piece 4 are non-adhesive portions 4F, 4R. This prevents stress from concentrating on the protruding piece 4 when the front surface 14F and back surface 12R are peeled off, and when the back surface 14R and back surface 13R are peeled off, thereby preventing damage from occurring.

The adhesive used to form the attachment sections 9U, 9D, and 9S has the property of bonding objects together by applying a pressure greater than a predetermined level, such as by folding the pieces together at each fold point, so that once the sheet pieces are peeled apart, they are less likely to be unintentionally bonded together.

As described above, when peeling the outermost first sheet piece 11 from the third sheet piece 13, the stress applied to the engagement portion 11S can be reduced, and damage during peeling can be effectively prevented. This allows the engagement portion 11S of the first sheet piece 11 to be securely engaged with the engagement portion 14S of the fourth sheet piece 14 to be assembled into an assembled state.

In addition, since the entire back surface of the protruding pieces 2, 3 is the non-adhesive portion 2R, 3R, the stress generated when peeling the first and third sheet pieces 11, 13 from each other does not act on the protruding pieces 2, 3, and the protruding pieces 2, 3 are not damaged. In addition, since no adhesive portion is formed, there is little frictional resistance between the protruding pieces 2, 3 and the protruding pieces 4 when engaging and releasing the engaged state, and the engaging and releasing state can be performed smoothly.

In this embodiment, the protruding pieces 2 and 3 are described as having the entire back surface of the non-adhesive portion 2R, 3R, but this is not limited thereto. As shown in FIG. 7, the adhesive portion 9U', 9D' may extend to the protruding pieces 2 and 3 to form an adhesive portion, and the non-adhesive portion 2R', 3R' may be formed near the slits 5, 6 in the protruding pieces 2 and 3. In this configuration, the adhesive portion is formed on the protruding pieces 2 and 3, which makes it easier to prevent unintentional peeling, for example, when using a mail sorting machine that automatically sorts mail or when mailing the information carrier 1. In addition, the non-adhesive portion 2R', 3R' is formed near the slits 5, 6, so that the stress when peeling the sheet pieces of the information carrier 1 is less likely to concentrate on the slits 5, 6 of the protruding pieces 2 and 3, and the engagement portion 11S can be prevented from being damaged.

As a result, when the party receiving the information carrier 1 removes the information carrier 1 from the delivery state, damage to the engaging parts 11S and 14S is prevented, and since the engaging parts 11S and 14S can be easily engaged and disengaged, the probability of the occurrence of the action of engaging the engaging parts 11S and 14S with each other and transforming them into a self-supporting assembled state can be increased.

The engaging portion 11S is formed symmetrically between the upper end edge 11U and the lower end edge 11D of the first sheet piece 11, and the engaging portion 14S is formed symmetrically between the upper end edge 14U and the lower end edge 14D of the fourth sheet piece 14. In other words, the protruding pieces 2 and 3, particularly the shape and position of the convex end edges 2b and 3c, are formed symmetrically between the upper end edge 11U and the lower end edge 11D of the first sheet piece 11, and the protruding piece 4, particularly the shape and position of the convex end edges 4b and 4c, are formed symmetrically between the upper end edge 14U and the lower end edge 14D of the fourth sheet piece 14. This not only ensures a good balance in the posture when the information holder 1 is erected in the assembled state, but also increases the structural strength in the assembled state.

In the above description, the protruding pieces 2 and 3 are formed on the engaging portion 11S, and the protruding piece 4 is formed on the engaging portion 14S. However, the present invention is not limited to this configuration, and the protruding piece 4 may be formed on the engaging portion 11S of the sheet piece 11 at one end side arranged on the outermost side, and the protruding pieces 2 and 3 may be formed on the engaging portion 14S of the sheet piece 14 at the other end side. In addition, three or more protruding pieces may be provided on the engaging portion, and the upper and lower end edges of the sheet pieces do not have to be symmetrical as long as the engaging portions can engage with each other.

In addition, the back surface 11R of the first sheet piece 11 is provided with an adhesive portion 9S that extends vertically in a straight line on the left-right inner side of the protruding pieces 2, 3. Therefore, compared to a configuration in which an adhesive portion is provided on the entire back surface 11R of the first sheet piece 11 including the protruding pieces 2, 3, for example, it is not necessary to provide an adhesive portion on the protruding pieces 2, 3, which have a complex shape and are at risk of being damaged due to stress concentration, and therefore it is possible to easily form an adhesive portion 9S that can effectively prevent unexpected peeling or damage when the information carrier 1 is delivered.

In addition, since the protruding piece 3 has a starting edge 3a formed on the opposite side of the slit 6, it is possible to visually encourage peeling to begin from the starting edge 3a side, and when peeling from the starting edge 3a side, the stress is less likely to concentrate on the weak part that constitutes the slit 6, so damage to the protruding piece 3 during peeling can be effectively prevented.

As described above, the side edges 2a, 3b of the protruding pieces 2, 3 and the side edge 4a of the protruding piece 4 are abutted against flat guides of a machine such as a folding machine (not shown) so that the folding and adhesive portions are formed while maintaining the phase. Since each side edge 2a, 3b, 4a is parallel to each of the folded portions A1 to C1, it is easy to use a machine such as a folding machine (not shown) to accurately fold the information carrier 1 along the folded portions A1 to C1 and to provide the adhesive portion 9S in a straight line parallel to each side edge 2a, 3b, 4a and each of the folded portions A1 to C1.

In addition, since each of the adhesive portions 9U, 9D, and 9S is formed on the back surface 11R, 12R, and 13R, the work process can be simplified compared to a configuration in which, for example, adhesive portions 9U, 9D, and 9S are provided separately on the front surface 13F and the back surface 11R is adhered to the front surface 13F.

Next, a modified example of the information carrier of the present invention will be described with reference to Figures 8 and 9. Note that in this explanation, explanations that overlap with information carrier 1 will be omitted.

As shown in FIG. 8, the information carrier 101 in an unfolded state has a fifth sheet piece 15 and a sixth sheet piece 16 arranged above the first to fourth sheet pieces 11 to 14, sandwiched between a perforated fold portion D1 shown by a dotted line and separated by a fold portion B2 shown by a two-dot chain line.

The first sheet piece 11 and the second sheet piece 12 are separated by a fold A2, which is perforated and indicated by a dotted line, and the third sheet piece 13 and the fourth sheet piece 14 are separated by a fold C2, which is perforated and indicated by a dotted line.

As shown in FIG. 9, adhesive layer 109U is formed along upper edge 15U on back surface 15R of fifth sheet piece 15, adhesive layer 109D is formed along lower edge 11D, 12D on back surfaces 11R, 12R of first and second sheet pieces 11, 12, adhesive layer 109S is formed parallel to folded portions B1, B2 of back surfaces 11R, 15R of first and fifth sheet pieces 11, 15, and the entire back surfaces of protruding pieces 2, 3 are non-adhesive portions 2R, 3R.

As a result, in the sent state, the information carrier 101 is folded starting from the folds B1 and B2 (not shown in the figure) so that the address, name, etc. of the recipient written on the surface 15F of the fifth sheet piece 15 (see Figure 8) is on the front side (outside).

In addition, because the adhesive layers 109D, 109U, and 109S are not formed on the protruding pieces 2 to 4, the protruding pieces 2 to 4 are less likely to be damaged when the information carrier 101 is expanded from the delivery state to the expanded state.

When assembling the information carrier 101 from the unfolded state to the assembled state, the fifth and sixth sheet pieces 15, 16 are first cut from the first to fourth sheet pieces 11 to 14 along the fold D2. Thereafter, the information carrier is assembled in the same manner as the information carrier 1. In this way, the information carrier may be configured so that some of the components of the information carrier are assembled to the assembled state.

Next, examples of information carriers that can be assembled into an assembled state will be described with reference to Figures 10 to 12. Note that descriptions that overlap with the information carriers 1 and 101 described above will be omitted.

As shown in FIG. 10, the information carrier 201 has a folded portion E1 formed at the engaging portion 111S of the first sheet piece 111, and a protruding piece 102 cut out in a convex shape formed on the outside of the folded portion E1. A folded portion E2 is formed at the engaging portion 114S of the fourth sheet piece 114, and a slit 104 is formed on the outside of the folded portion E2. The information carrier 201 in the unfolded state can be assembled in the same manner as the information carrier 101, by cutting off the fifth and sixth sheet pieces 15, 16 from the first to fourth sheet pieces 111 to 114, folding them along the respective folding portions A2, B1, C2, and then engaging the protruding piece 102 cut and raised from the folded portion E1 with the engaging portion 114S through the slit 104.

As shown in FIG. 11, the information carrier 301 has the seventh sheet piece 17 disposed to the left of the first to fourth sheet pieces 111 to 114, sandwiching the fold D2 indicated by the two-dot chain line. The information carrier 301 in the unfolded state can be assembled in the same manner as the information carrier 201, by cutting the seventh sheet piece 17 from the first to fourth sheet pieces 111 to 114, folding them along the respective folds A2, B3, and C2, and then engaging the protruding piece 102, cut and raised from the fold E1, with the engaging portion 114S through the slit 104.

As shown in FIG. 12, the information carrier 401 has a rectangular first sheet piece 211 and a fourth sheet piece 214.
