As illustrated in FIG. 2 , the imaging device 1 is a four-color based full-color laser printer that forms a color image on a recording medium S using an electrophotographic process. The imaging apparatus 1 is of a process cartridge type, and a removable cartridge is installed in the apparatus main body 2 of the imaging apparatus 1 to form a color image on the recording medium S. It is assumed here that the side of the imaging apparatus 1 on which the opening and closing door 3 is disposed is the front (front), and the side opposite to the front is the back (rear). The right side of the imaging device 1 when viewed from the front is called a driving side, and the left side is called a driven side.

In the main body 2 of the equipment, the four cassettes P (PY, PM, PC, PK) are the first cassette PY, the second cassette PM, the third cassette PC, and the fourth cassette PK, which are arranged in the horizontal direction. The first to fourth cartridges P (PY, PM, PC, PK) each include a similar electrophotographic process mechanism that processes a different color of developer (hereinafter referred to as toner). The first to fourth cartridges P (PY, PM, PC, PK) respectively store yellow (Y), magenta (M), cyan (C), and black (K) toners.

Each box PY, PM, PC, and PK of an individual color has the same structure, so the boxes PY, PM, PC, and PK are collectively called box P. The rotational driving force is transferred to the cartridge P from the drive output part (not shown) of the apparatus main body 2 . Furthermore, bias voltage (for example, charging bias voltage, developing bias voltage) is supplied to the cartridge P via the bias voltage supply part (not shown) of the apparatus main body 2 . ＜General structure of box＞

As illustrated in FIG. 3A , the cartridge P of the specific aspect 1 includes: an electrophotographic photosensitive member 4 (hereinafter referred to as a photosensitive drum); and a drum unit 8 (first unit) including a charging unit (which acts on the photosensitive drum). 4) and cleaning unit. Further, the cartridge P includes a developing device 9 (second unit) including a developing unit to develop the electrostatic latent image on the photosensitive drum 4 . The drum unit 8 and the developing device 9 are interconnected. Here, the charging roller 5 is used for the charging unit, the cleaning blade 7 is used for the cleaning unit, and the developer carrying member (hereinafter referred to as a developing roller) 6 is used for the developing unit. A more specific architecture of the box P will be described later.

As illustrated in FIG. 2 , the laser scanner unit LB (exposure unit) is arranged above the cassette P. The laser scanner unit LB outputs the laser beam Z according to the image information. The laser beam Z then passes through the exposure window 10 of the cartridge P to scan and expose the surface of the photosensitive drum 4. The intermediate transfer belt unit 11 (transfer member) is arranged below the cassette P. The intermediate transfer belt unit 11 includes a drive roller 13, a support roller 14, and a tension roller 15, and stretches the elastic transfer belt 12. The lower surface of the photosensitive drum 4 is in contact with the upper surface of the transfer belt 12 . The contact portion between the photosensitive drum 4 and the transfer belt 12 is the main transfer portion. Each main transfer roller 16 is disposed on the inner side of the transfer belt 12 so as to face each photosensitive drum 4 .

The support roller 14 faces the secondary transfer roller 17 via the transfer belt 12 . The contact between the transfer belt 12 and the secondary transfer drum 17 is a secondary transfer unit. The feeding unit 18 may be arranged below the intermediate transfer belt unit 11 . The feeding unit 18 includes a paper feeding tray 19 (where the recording media S is stacked and accommodated) and a paper feeding roller 20 . The fixing unit 21 and the discharge unit 22 are arranged on the upper left side of the apparatus main body 2 in FIG. 2 . The discharge tray 23 is arranged on the upper surface of the apparatus main body 2 . The toner image is fixed to the recording medium S by the fixing member disposed in the fixing unit 21 , and the recording medium S is discharged to the discharge tray 23 . ＜Box structure＞

4A and 4B are perspective views of the box P according to the specific aspect 1 when viewed from different angles. Figure 4A is a perspective view when the cartridge P is viewed from the driving side. Figure 4B is a perspective view when the cartridge P is viewed from the driven side. The cartridge P has an approximately rectangular parallelepiped shape, and its longitudinal direction (X direction) is the direction of the rotation axis b of the photosensitive drum 4 . The cartridge P has a two-frame structure in which the driving side support member 24 and the driven side support member 25 fixed to the drum unit 8 are rotatably supported by the hub center (dashed line in FIG. 4A ) of the developing device 9 as the center.

As illustrated in FIG. 3A , the drum unit 8 includes a drum frame 26 including a photosensitive drum 4 , a charging roller 5 , and a cleaning blade 7 . As illustrated in FIGS. 4A and 4B , the photosensitive drum 4 is rotatably supported by a driving side support member 24 and a driven side support member 25 . The drive side support member 24 and the driven side support member 25 may be regarded as parts of the drum frame 26 . Upon receiving the driving force of the motor (not shown) of the apparatus main body 2 from the drum driving coupler 4a, the photosensitive drum 4 is rotationally driven in the direction of arrow D in FIG. 3A. As demonstrated in FIG. 3A , both ends of the charging drum 5 are rotatably supported by charging drum bearings 27 of the drum frame 26 . The charging roller 5 contacts the surface of the photosensitive drum 4 so as to be rotated by the rotation of the photosensitive drum 4, and receives a charging bias to charge the surface of the photosensitive drum 4. In order to charge the surface of the photosensitive drum 4 uniformly, both ends of the charging roller 5 are pressed against the surface of the photosensitive drum 4 by the charging roller pressure springs 28 .

The cleaning blade 7 is fixed to the drum frame 26, and the elastic rubber portion at the tip of the cleaning blade 7 contacts the photosensitive drum 4 in the opposite direction of the rotation direction of the photosensitive drum 4 (arrow D direction in FIG. 3A). When an image is formed, the cleaning blade 7 scrapes off the untransferred toner remaining on the photosensitive drum 4, thus cleaning the surface of the photosensitive drum 4. The untransferred toner scraped off the surface of the photosensitive drum 4 by the cleaning blade 7 is stored in the waste toner storage portion 26 a of the drum frame 26 as waste toner.

As demonstrated in FIGS. 3A and 7 , the developing device 9 is a horizontally elongated developing unit extending in the direction of the rotation axis of the developing roller 6 . The longitudinal direction of the developing device 9 matches the direction of the rotation axis of the developing roller 6 . As demonstrated in FIG. 7 , in addition to the developing roller 6 , the developing device 9 also includes a developing frame 29 , a developing blade 31 , and a developer feeding roller 33 . Further, as illustrated in FIG. 3A , the cartridge P includes a toner storage container 29c to store toner. The toner storage container 29c includes a developing frame 29, and the developing frame 29 has an opening 29b connected to the toner storage container 29c. The developing roller 6 is disposed in the opening 29 b of the developing frame 29 , and part of the developing roller 6 is exposed from the developing frame 29 .

As shown in FIG. 7 , the two shaft ends (core members) 6 a of the developing roller 6 are rotatably supported by a driving side bearing 38 and a driven side bearing 39 , which are respectively installed on each side of the developing frame 29 . The driving side bearing 38 and the driven side bearing 39 may be regarded as parts of the developing frame 29 . The developing roller gear 40 and the feed roller gear 41 are respectively arranged on the driving side end of the core member 6a of the developing roller 6 and the driving side end of the core member 33a of the developer feed roller 33. The developing roller gear 40 and the feed roller gear 41 are engaged with the developing drive input gear 42 . The development drive input gear 42 includes a development drive coupler 42a. By a drive output coupler (not shown) on the apparatus main body 2 side-joined to the development drive coupler 42a, the driving force of the drive motor (not shown) of the apparatus main body 2 is transferred to the development drive input gear 42, and development is performed The roller 6 and the developer feed roller 33 are rotationally driven at a predetermined speed.

The free end in the shorter direction of the developing blade 31 contacts the developing roller 6 in the opposite direction to the rotation direction of the developing roller 6 (arrow E direction in FIG. 3A ). The developing device (developing unit) 9 is centered on the axis a (hub center) in Figure 4A, and is supplied with energy by a pressure spring (not shown) in the direction in which the developing roller 6 contacts the photosensitive drum 4 (arrow W1 in Figure 3A direction), and the developing roller 6 contacts the photosensitive drum 4. On the other hand, FIG. 3B indicates a state in which the developing roller 6 is released from the photosensitive drum 4. When an image is formed, the developer feed roller 33 and the developing roller 6 rotate and rub against each other, whereby the toner in the developing frame 29 is brought to the developing roller 6 . The developing blade 31 regulates the thickness of the toner layer formed on the peripheral surface of the developing roller 6 and also supplies the toner with triboelectric charges generated by contact pressure between the developing blade 31 and the developing roller 6 . The charged toner on the developing roller 6 then adheres to the electrostatic latent image on the photosensitive drum 4 at the contact portion between the developing roller 6 and the photosensitive drum 4, thereby developing the electrostatic latent image. ＜Structure of packaging materials＞

FIG. 1A is a diagram of the corrugated board packaging material 100A in an unfolded state before assembly, and FIG. 1B is a diagram of the corrugated board packaging material 100A after assembly. 5 is a diagram showing a state in which the box P is inserted between the corrugated board packaging material 100A and the corrugated board packaging material 100B, so that the corrugated board packaging material 100A and the corrugated board packaging material 100B are attached to the box P. By attaching the corrugated board packaging material 100A and the corrugated board packaging material 100B to the box P, the box P can be protected from vibration and impact. The corrugated board packaging material 100A and the corrugated board packaging material 100B have the same structure.

In the longitudinal direction of the box P, the corrugated board packaging material 100A is attached to the first edge of the box P, and the corrugated board packaging material 100B is attached to the second edge of the box P. The longitudinal direction of the cartridge P matches the direction of the rotation axis of the photosensitive drum 4 . When the cartridge P is viewed in a direction perpendicular to the longitudinal direction, the corrugated board packaging materials 100A and 100B do not overlap the center of the toner storage container 29 c and the center of the waste toner storage portion 26 a in the longitudinal direction of the cartridge P. The spaces of the waste toner storage portion 26a and the toner storage container 29c exist within the cartridge P in the longitudinal central region, so when an external force is applied to the cartridge P, the drum frame 26 and the developing frame 29 are more easily deformed. By attaching the corrugated board packaging materials 100A and 100B away from the central area of the cartridge P in the longitudinal direction, deformation of the drum frame 26 and the developing frame 29 caused by vibration and impact can be avoided. Furthermore, it is preferable that when the box P is viewed from the longitudinal direction perpendicular to the box P, the gap between the corrugated board packaging material 100A and the packaging object (box P, or the bag or sheet surrounding the box P) The contact portion does not overlap the toner storage container 29c and the waste toner storage portion 26a.

In order to protect the cartridge P from dust and the like, the cartridge P may be covered by a bag or sheet (not shown). Bags or sheets may be placed outside box P and corrugated board packaging material 100A and 100B, or may be placed between box P and corrugated board packaging material 100A and between box P and corrugated board packaging material 100B. The box P to which the corrugated board packaging materials 100A and 100B are attached is inserted into a corrugated board box (not shown). In this case, the corrugated board packaging materials 100A and 100B can protect the box P from shock and impact applied from outside the corrugated board box. ＜Structure of corrugated board packaging materials＞

The structure of the corrugated board packaging material 100A will be described with reference to FIG. 1A. The corrugated board packaging material 100A will be described below, but the same description can also be applied to the corrugated board packaging material 100B. The corrugated board packaging material 100A as a packaging member is formed by folding a sheet (corrugated board sheet) having a front and a back, and is attached to a box P. The sheet is composed of corrugated board, for example. The corrugated board packaging material 100A includes a base, a plurality of receiving parts, and a plurality of regulating parts. Specifically, the corrugated board packaging material 100A includes: a base 101 (main part), which has a first opening 105 (base opening); a first receiving part 102 and a second receiving part 152, which are connected to the base 101; and fourth connecting parts 103 and 104 (regulating parts).

The first receiving part 102 of the receiving box P includes a first connecting part 102a, a second connecting part 102b, and a third connecting part 102c. The first connection part 102a is connected to the base part 101, the second connection part 102b is connected to the first connection part 102a, and the third connection part 102c is connected to the second connection part 102b. The corrugated board packaging material 100A has a first fold line 111 at the boundary between the base 101 and the first connecting portion 102a. The corrugated board packaging material 100A also has a second fold line 112 at the boundary between the first connection portion 102a and the second connection portion 102b. Furthermore, the corrugated board packaging material 100A has a third fold line 113 (113a, 113b) at the boundary between the second connection part 102b and the third connection part 102c. The first folding line 111, the second folding line 112, and the third folding line 113 extend in the same direction.

In the first receiving portion 102, the second opening 106 is formed as an insertion opening for inserting the cartridge P. The second opening 106 is formed in the second connection part 102b and the third connection part 102c, and the second opening 106 is arranged to overlap a line (not shown) connecting the third folding line 113a and the third folding line 113b. The third connection portion 102c includes third openings 108 and 109, which are engagement openings. The third connecting portion 102c also includes a first insertion portion 107 protruding from the corrugated board in a direction intersecting the direction in which the third fold line 113 extends. The first insertion portion 107 protrudes in a direction away from the position of the second opening 106 . The third connection part 102c is arranged between the second opening 106 and the first insertion part 107. The first insertion portion 107 is disposed in the third connecting portion 102c so as to be located between the third opening 108 and the third opening 109 in the direction of the third fold line 113 .

The second receiving part 152 for receiving the box P has the same structure as the first receiving part 102 . The first receiving part 102 and the second receiving part 152 are formed approximately symmetrically with respect to the base part 101 . Specifically, the first connection part 152a, the second connection part 152b, and the third connection part 152c are formed to be approximately symmetrical to the first connection part 102a, the second connection part 102b, and the third connection part 102c respectively. Just like the first receiving part 102, the second receiving part 152 includes a second opening 156, a first insertion part 157, third openings 158 and 159 (joining openings), a first folding line 161, a second folding line 162, a third folding line 163 .

The fourth connecting portions 103 and 104 are connected to the base portion 101 such that the fourth connecting portions 103 and 104 face each other via the base portion 101 . The first opening 105 is arranged between the fourth connection part 103 and the fourth connection part 104 . The corrugated board packaging material 100A has a fourth fold line 114 at the boundary between the base portion 101 and the fourth connection portion 103 , and has a fourth fold line 164 at the boundary between the base portion 101 and the fourth connection portion 104 . The fourth folding lines 114 and 164 extend in a direction that crosses the direction in which the first folding line 111 , the second folding line 112 , and the third folding line 113 extend. Preferably, the fourth folding lines 114 and 164 are perpendicular to the directions in which the first folding line 111 , the second folding line 112 and the third folding line 113 extend.

The fourth connection part 103 includes second insertion parts 103a and 103b as engagement parts, and the fourth connection part 104 includes second insertion parts 104a and 104b as engagement parts. Each of the second insertion portions 103a, 103b, 104a, and 104b has a hook shape. In other words, the fourth connection part 103 includes second insertion parts 103a and 103b, which protrude in the direction in which the fourth fold line 114 extends; the fourth connection part 104 includes second insertion parts 104a and 104b, which are located where the fourth fold line 164 extends. Protruding in the direction of extension. The second insertion portion 103a and the second insertion portion 103b protrude in opposite directions to each other, and the second insertion portion 104a and the second insertion portion 104b protrude in the opposite directions to each other. Further, the second insertion portions 103a and 104a protrude in approximately the same direction, and the second insertion portions 103b and 104b protrude in approximately the same direction.

In FIG. 1A , the first to fourth fold lines 111 , 112 , 113 , 161 , 162 , 163 , 114 , and 164 are indicated by thick lines. The thin lines (other non-thick lines) in the corrugated board packaging material 100A indicate the cutting lines when the corrugated board packaging material 100A is cut from the corrugated board. This is also true for FIG. 6A , FIG. 8A , and FIG. 9A mentioned later. ＜Assembly of corrugated board packaging materials＞

The assembly of corrugated board packaging material 100A will be described with reference to FIG. 1B. The first connecting part 102a is folded to the base 101 from the back of the corrugated board toward the front of the corrugated board at the first folding line 111, so that the first folded part is formed between the base 101 and the first connecting part 102a. The second connecting part 102b is folded to the first connecting part 102a at the second folding line 112 from the back of the corrugated board toward the front of the corrugated board, so that the second folded part is formed between the first connecting part 102a and the second connecting part 102b. The third connecting part 102c is folded to the second connecting part 102b at the third folding line 113 from the back of the corrugated board toward the front of the corrugated board, so that the third folded part is formed between the second connecting part 102b and the third connecting part 102c.

In the corrugated board packaging material 100A, the first closed loop is formed by the base part 101, the first connecting part 102a, the second connecting part 102b, and the third connecting part 102c. The first closed loop formed by the base part 101 and the first receiving part 102 therefore has three folds. The first connection part 152a, the second connection part 152b, and the third connection part 152c are also folded in the same manner as the first connection part 102a, the second connection part 102b, and the third connection part 102c. In the corrugated board packaging material 100A, the second closed loop is formed by the base part 101, the first connecting part 152a, the second connecting part 152b, and the third connecting part 152c. The second closed loop formed by the base 101 and the first receiving part 152 therefore has three folds. In FIG. 1B , the corrugated board packaging material 100A has two approximately rectangular closed loops. A closed loop refers to a shape whose starting point and end point match (such as a circle, an ellipse), and has, for example, shape portions including curves (whose curvature is different from other areas), triangles, squares, and the like.

When the first closed loop is formed by the base part 101 and the first receiving part 102, and the first insertion part 107 is inserted into the first opening 105, the third connecting part 102c is engaged with the base part 101. When the second closed loop is formed by the base part 101 and the second receiving part 152, and the first insertion part 157 is inserted into the first opening 105, the third connecting part 152c is engaged with the base part 101. In the corrugated board packaging material 100A, the space for inserting the box P is generated by the second opening 106 of the first receiving part 102 and the second opening 156 of the second receiving part 152 . The second opening 106 is configured such that the position of the second opening 106 in the circumferential direction of the first closed loop overlaps the position of the third folded portion formed between the second connecting portion 102b and the third connecting portion 102c. The second opening 156 is configured such that the position of the second opening 156 in the circumferential direction of the second closed loop overlaps the position of the third folded portion formed between the second connecting portion 152b and the third connecting portion 152c.

The fourth connecting part 103 is folded to the base 101 from the back of the corrugated board toward the front of the corrugated board at the fourth folding line 114 , so that the fourth folded part is formed between the base 101 and the fourth connecting part 103 . The fourth connecting part 104 is folded to the base 101 from the back of the corrugated board toward the front of the corrugated board at the fourth folding line 164 , so that the fourth folded part is formed between the base 101 and the fourth connecting part 104 . When the second insertion parts 103b and 104b are inserted into the third openings 108 and 109 respectively, the second insertion parts 103b and 104b are engaged with the third connection part 102c. The second insertion portions 103b and 104b are engaged with the third connecting portion 102c, thus preventing the first closed loop from opening. When the second insertion parts 103a and 104a are inserted into the third openings 158 and 159 respectively, the second insertion parts 103a and 104a are engaged with the third connection part 152c. The second insertion portions 103a and 104a are engaged with the third connection portion 152c, thus preventing the second closed loop from opening.

As illustrated in Figure 1B, the second insertion portion 103b is inserted into the third opening 108 from outside the first closed loop, and the second insertion portion 104b is inserted into the third opening 109 from outside the first closed loop. When the first closed loop is opened, since the third connection part 102c moves in a direction close to the fourth connection parts 103 and 104, the movement of the third connection part 102c can be regulated by the fourth connection parts 103 and 104. As a result, opening of the first closed loop can be avoided with greater certainty. As illustrated in FIG. 1B , the second insertion portion 103a is inserted into the third opening 158 from outside the second closed loop, and the second insertion portion 104a is inserted into the third opening 159 from outside the second closed loop. When the second closed loop is opened, since the third connection part 152c moves in a direction close to the fourth connection parts 103 and 104, the movement of the third connection part 152c can be regulated by the fourth connection parts 103 and 104. As a result, opening of the second closed loop can be avoided with greater certainty.

By the fourth connecting portions 103 and 104 contacting the third connecting portions 102c and 152c, the fourth connecting portions 103 and 104 regulate the movement of the third connecting portions 102c and 152c in a direction parallel to the surface of the base 101. Furthermore, when the second insertion parts 103b and 104b are inserted into the third openings 108 and 109 respectively, the fourth connection parts 103 and 104 regulate the movement of the third connection part 102c in a direction perpendicular to the surface of the base part 101. Furthermore, when the second insertion parts 103a and 104a are inserted into the third openings 158 and 159 respectively, the fourth connection parts 103 and 104 regulate the movement of the third connection part 152c in a direction perpendicular to the surface of the base part 101.

The first connecting parts 102a and 152a, the second connecting parts 102b and 152b, the third connecting parts 102c and 152c, and the fourth connecting parts 103 and 104 are folded from the back of the corrugated board toward the front of the corrugated board. Since the folding directions of the first connecting parts 102a and 152a, the second connecting parts 102b and 152b, the third connecting parts 102c and 152c, and the fourth connecting parts 103 and 104 are all the same, the corrugated board packaging material 100A is easy to assemble.

The direction in which the closed loop formed by the base 101 and the first receiving part 102 opens and the direction in which the closed loop formed by the base 101 and the first receiving part 152 opens is perpendicular or approximately perpendicular to the direction of the back surface of the base 101 . Furthermore, the direction of releasing the engagement state of the fourth connecting portions 103 and 104 with the first receiving portion 102 and the direction of releasing the engaging state of the fourth connecting portions 103 and 104 with the second receiving portion 152 are parallel or approximately parallel to the base. The direction of the back of 101. Furthermore, the direction in which the engagement state of the fourth connecting parts 103 and 104 and the first receiving part 102 is released is a direction in which the closed loop formed by the base part 101 and the first receiving part 102 becomes smaller. The direction in which the engagement state of the fourth connecting parts 103 and 104 and the second receiving part 152 is released is a direction in which the closed loop formed by the base part 101 and the second receiving part 152 becomes smaller. The direction in which the closed loop formed by the base part 101 and the first receiving part 102 is opened is different from the direction in which the engagement state of the fourth connecting parts 103 and 104 with the first receiving part 102 is released. Furthermore, the direction in which the closed loop formed by the base part 101 and the second receiving part 152 is opened is different from the direction in which the engagement state of the fourth connecting parts 103 and 104 and the second receiving part 152 is released. As a result, when a shock or impact is applied, it is possible to prevent the folded portion of the corrugated board packaging material 100A from returning to the previous state before folding and allowing the corrugated board packaging material 100A to spread.

The directions of the first folding lines 111, 161, the second folding lines 112, 162 and the third folding lines 113, 163 intersect with the directions of the fourth folding lines 114 and 164. Therefore, when vibration or impact is applied, the fourth connection parts 103 and 104 can receive force from the first receiving part 102 and the second receiving part 152 along the surface of the base part 101. In other words, the fourth connecting parts 103 and 104 may receive a force for opening the first closed loop and a force for opening the second closed loop along the surfaces of the fourth connecting parts 103 and 104. The fourth connecting parts 103 and 104 are configured to extend in a direction perpendicular to each surface of the third connecting parts 102c and 152c. Therefore, even if a force along the surface of the base portion 101 is applied to the fourth connecting portions 103 and 104 via the first receiving portion 102 and the second receiving portion 152, the fourth connecting portions 103 and 104 will not undergo much deformation. As a result, when shock or impact is applied, the closed loop of the corrugated board packaging material 100A is not easily opened, and the folded portion of the corrugated board packaging material 100A can be prevented from returning to the previous state before folding.

The corrugated board packaging material 100A attached to the box P contacts the box P and the section of the corrugated board of the corrugated board packaging material 100A, and absorbs shock and impact during transportation by the corrugated board deforming in a direction pushing against the corrugated board section. The strength in the direction pushing toward the cross section of the corrugated board (the direction parallel to the sheet surface) is stronger than the strength in the direction pushing toward the sheet surface (front and back) of the corrugated board (the direction perpendicular to the sheet surface). Therefore, the corrugated board packaging material 100A can absorb strong vibration and impact. First insertion parts 107 and 157, second insertion parts 103a, 103b, 104a and 104b, first opening 105, second openings 106 and 156, third openings 108, 109, 158 and 159, fourth connection parts 103 and 104 The number of each may be appropriately set as needed. The respective numbers of these members and openings are therefore not limited to Figures 1A and 1B. ＜＜Specific form 2＞＞

Another specific aspect of the present invention will be described as specific aspect 2 with reference to FIGS. 6A and 6B. The difference between the specific aspect 1 and the specific aspect 2 will be described below, and the description of the redundant content of the specific aspect 1 will be omitted. FIG. 6A is an illustration of the corrugated board packaging material 200 in an unfolded state before assembly, and FIG. 6B is an illustration of the corrugated board packaging material 200 after assembly. ＜Structure of corrugated board packaging materials＞

The architecture of corrugated board packaging material 200 will be described with reference to Figure 6A. The corrugated board packaging material 200 (packaging member) is formed by folding a sheet having a front side and a back side, and is attached to the box P. The corrugated board packaging material 200 includes a base part, a plurality of receiving parts, and a plurality of regulating parts. Specifically, the corrugated board packaging material 200 includes: a base portion (main portion) 201 having a first opening 205 (base opening); a first receiving portion 202 and a second receiving portion 252 connected to the base portion 201; and a fourth Connection parts 203 and 204 (control parts). The second insertion parts 203a and 203b of the fourth connection part 203 and the second insertion parts 204a and 204b of the fourth connection part 204 are the same as the specific aspect 1.

The first receiving part 202 for receiving the box P includes a first connecting part 202a, a second connecting part 202b, and a third connecting part 202c. In the first receiving portion 202, the second opening 206 is formed as an insertion opening for inserting the cartridge P. The second receiving part 252 for receiving the box P has the same structure as the first receiving part 202. The first receiving part 202 and the second receiving part 252 are formed approximately symmetrically with respect to the base part 201 . Specifically, the first connection part 252a, the second connection part 252b, and the third connection part 252c are approximately symmetrical to the first connection part 202a, the second connection part 202b, and the third connection part 202c respectively.

The corrugated board packaging material 200 includes a fifth connecting portion 221 (221a, 221b, 221c, 221d), which is an opening connecting portion extending from the edge of the second opening 206. The corrugated board packaging material 200 has a fifth fold line 222 (222a, 222b, 222c, 222d). The corrugated board packaging material 200 has a fifth fold line 222a at the boundary between the second connecting portion 202b and the fifth connecting portion 221a. The corrugated board packaging material 200 has a fifth fold line 222b at the boundary between the second connecting portion 202b and the fifth connecting portion 221b. The corrugated board packaging material 200 has a fifth fold line 222c at the boundary between the second connecting portion 202b and the fifth connecting portion 221c. The corrugated board packaging material 200 has a fifth fold line 222d at the boundary between the third connecting portion 202c and the fifth connecting portion 221d. The fifth fold lines 222a and 222c extend in a direction crossing the directions in which the first fold line 211, the second fold line 212, and the third fold line 213 (213a and 213b) extend. The extending directions of the fifth folding lines 222b and 222d are the same as the extending directions of the first folding line 211, the second folding line 212, and the third folding line 213.

In the second receiving portion 252, the second opening 256 is formed as an insertion opening for inserting the cartridge P. The corrugated board packaging material 200 includes a fifth connecting portion 271 (271a, 271b, 271c, 271d) and a fifth fold line 272 (272a, 272b, 272c, 272d). The fifth connecting portion 271 is the same as the fifth connecting portion 221 , and the fifth folding line 272 is the same as the fifth folding line 222 . The first folding lines 211 and 261, the second folding lines 212 and 262, the third folding lines 213 and 263 (263a and 263b), the fourth folding lines 214 and 264, and the first insertion portions 207 and 257 are the same as the specific aspect 1. ＜Assembly of corrugated board packaging materials＞

The assembly of corrugated board packaging material 200 will be described with reference to Figure 6B. The folding of the first connection part 202a, the second connection part 202b, and the third connection part 202c is the same as in the specific aspect 1. In the corrugated board packaging material 200, the first closed loop is formed by the base part 201, the first connecting part 202a, the second connecting part 202b, and the third connecting part 202c. The first closed loop formed by the base part 201 and the first receiving part 202 therefore has three folds. The first connection part 252a, the second connection part 252b, and the third connection part 252c are also folded in the same manner as the first connection part 202a, the second connection part 202b, and the third connection part 202c. In the corrugated board packaging material 200, the second closed loop is formed by the base part 201, the first connecting part 252a, the second connecting part 252b, and the third connecting part 252c. The second closed loop formed by the base 201 and the first receiving part 252 thus has three folds. As shown in FIG. 6B , the corrugated board packaging material 200 has two approximately rectangular closed loops.

The fifth connecting portion 221a is folded to the second connecting portion 202b at the fifth folding line 222a from the back of the corrugated board toward the front of the corrugated board, so that the fifth folded portion is formed between the second connecting portion 202b and the fifth connecting portion 221a. The fifth connecting portion 221b is folded to the second connecting portion 202b at the fifth fold line 222b from the back of the corrugated board toward the front of the corrugated board. In this way, the fifth folded portion is formed between the second connecting portion 202b and the fifth connecting portion 221b. The fifth connecting portion 221c is folded to the second connecting portion 202b at the fifth fold line 222c from the back of the corrugated board toward the front of the corrugated board. In this way, the fifth folded portion is formed between the second connecting portion 202b and the fifth connecting portion 221c. The fifth connecting portion 221d is folded to the third connecting portion 202c at the fifth folding line 222d from the back of the corrugated board toward the front of the corrugated board. In this way, the fifth folded portion is formed between the third connecting portion 202c and the fifth connecting portion 221d.

The fourth connecting part 203 is folded to the base 201 from the back of the corrugated board toward the front of the corrugated board at the fourth folding line 214 , so that the fourth folded part is formed between the base 201 and the fourth connecting part 203 . The fourth connecting part 204 is folded to the base 201 from the back of the corrugated board toward the front of the corrugated board at the fourth folding line 264 , so that the fourth folded part is formed between the base 201 and the fourth connecting part 204 . When the second insertion parts 203b and 204b are inserted into the second opening 206, the second insertion parts 203b and 204b are engaged with the third connection part 202c. When the second insertion parts 203a and 204a are inserted into the second opening 256, the second insertion parts 203a and 204a are engaged with the third connection part 252c. The second insertion portions 203b and 204b are engaged with the third connecting portion 202c, thus preventing the first closed loop from opening. The second insertion portions 203a and 204a are engaged with the third connection portion 252c, thus preventing the second closed loop from opening.

As demonstrated in Figure 6B, the second insertion portions 203b and 204b are inserted into the second opening 206 from outside the first closed loop. When the first closed loop is opened, since the third connection part 202c moves in the direction close to the fourth connection parts 203 and 204, the movement of the third connection part 202c can be regulated by the fourth connection parts 203 and 204, that is, Like concrete form 1. As a result, opening of the first closed loop can be avoided with greater certainty. As demonstrated in Figure 6B, the second insertion portions 203a and 204a are inserted into the second opening 256 from outside the second closed loop. When the second closed loop is opened, since the third connection part 252c moves in the direction close to the fourth connection parts 203 and 204, the movement of the third connection part 252c can be regulated by the fourth connection parts 203 and 204, that is, Like concrete form 1. As a result, opening of the second closed loop can be avoided with greater certainty.

Since the folding directions of the first connecting parts 202a and 252a, the second connecting parts 202b and 252b, the third connecting parts 202c and 252c, the fourth connecting parts 203 and 204, and the fifth connecting parts 221 and 272 are all the same, the corrugated board packaging Assembly of Material 200 is easy. Furthermore, in the specific aspect 2, just like the specific aspect 1, when a shock or impact is applied, it is possible to prevent the folded portion of the corrugated board packaging material 200 from returning to the previous state before folding and allowing the corrugated board packaging material 200 to spread.

In some cases, when the box P directly contacts the cross section of the corrugated board of the corrugated board packaging material 200, the box P may be scratched by vibration or impact. In specific aspect 2, the fifth connecting portions 221 and 271 are disposed in the corrugated board packaging material 200, so the box P contacts the fifth fold lines 222 and 272, and the box P does not contact the corrugated board section of the corrugated board packaging material 200. As a result, when the corrugated board packaging material 200 is attached to the box P, scratching the box P can be avoided.

The second insertion parts 203a and 204a are inserted into the second opening 256, and the second insertion parts 203b and 204b are inserted into the second opening 206. Thereby, the second insertion portions 203a and 204a are arranged between the box P and the third connection portion 202c, and the second insertion portions 203a and 204a are arranged between the box P and the third connection portion 252c. As a result, when the corrugated board packaging material 200 is attached to the box P, scratching the box P can be avoided.

Each of the first insertion portions 207 and 257, the second insertion portions 203a, 203b, 204a and 204b, the first opening 205, the second openings 206 and 256, the fourth connection portions 203 and 204, and the fifth connection portions 221 and 271 The number may be appropriately set as needed. The respective numbers of these members and openings are therefore not limited to Figures 6A and 6B. Furthermore, like aspect 1, two corrugated board packaging materials 200 may be attached to the box P. For example, a first corrugated board packaging material 200 may be attached to a first edge of the box P, and a second corrugated board packaging material 200 may be attached to a second edge of the box P. ＜＜Specific form 3＞＞

Another specific aspect of the present invention will be described as specific aspect 3 with reference to FIGS. 8A and 8B . The difference between the specific aspect 1 and the specific aspect 3 will be described below, and the description of the redundant content of the specific aspect 1 will be omitted. 8A is an illustration of the corrugated board packaging material 300 in an unfolded state before assembly, and FIG. 8B is an illustration of the corrugated board packaging material 300 after assembly. ＜Structure of corrugated board packaging materials＞

The structure of the corrugated board packaging material 300 will be described with reference to FIG. 8A. The corrugated board packaging material 300 (packaging member) is formed by folding a sheet having a front side and a back side, and is attached to a box P. The corrugated board packaging material 300 includes a base, a plurality of receiving portions, and a plurality of regulating portions. Specifically, the corrugated board packaging material 300 includes: a base (main portion) 301 having a first opening 305 (base opening); a first receiving portion 302 and a second receiving portion 352 connected to the base 301; and fourth connecting portions 303 and 304 (regulating portions). The second inserting portions 303a and 303b of the fourth connecting portion 303 and the second inserting portions 304a and 304b of the fourth connecting portion 304 are the same as those of the specific embodiment 1.

The fifth connecting portion 333 is approximately U-shaped and has a groove. The fifth connection part 333 has a groove at the tip part, and the root part of the fifth connection part 333 is connected to the second connection part 302b. The corrugated board packaging material 300 has a fifth fold line 334 at the boundary between the second connecting portion 302b and the fifth connecting portion 333. The direction in which the fifth fold line 334 extends is the same as the direction in which the first fold line 311, the second fold line 312, and the third fold line 313 (313a and 313b) extend.

The corrugated board packaging material 300 includes a fifth connecting portion 383 , which is an opening connecting portion extending from the edge of the second opening 356 . The fifth connection portion 383 has a rectangular or approximately rectangular shape. The corrugated board packaging material 300 has a fifth fold line 384 at the boundary between the second connecting portion 352b and the fifth connecting portion 383. The direction in which the fifth fold line 384 extends is the same as the direction in which the first fold line 361, the second fold line 362, and the third fold line 363 (363a and 363b) extend.

The corrugated board packaging material 300 includes a sixth connecting portion 331 that is connected to the supporting portion of the first connecting portion 302a. The sixth connecting portion 331 has a stepped shape, and a portion constituting the bottom of the stepped shape is connected to the first connecting portion 302a. The corrugated board packaging material 300 has a sixth fold line 332 (support fold line) at the boundary between the first connection part 302a and the sixth connection part 331. The sixth fold line 332 extends in a direction that intersects the directions in which the first fold line 311 , the second fold line 312 , and the third fold line 313 extend.

The corrugated board packaging material 300 includes a sixth connecting portion 381 that is connected to the supporting portion of the first connecting portion 352a. The sixth connecting portion 381 has a stepped shape, and a portion constituting the bottom of the stepped shape is connected to the first connecting portion 352a. The corrugated board packaging material 300 has a sixth fold line 382 (support fold line) at the boundary between the first connection part 352a and the sixth connection part 381. The sixth fold line 382 extends in a direction that crosses the directions in which the first fold line 361 , the second fold line 362 , and the third fold line 363 extend. The sixth connection part 381 also includes a third insertion part 381a protruding in a direction close to the position of the base part 301.

The corrugated board packaging material 300 includes a seventh connecting portion 335 that is connected to the support portion of the fourth connecting portion 303 . The seventh connecting portion 335 is, for example, rectangular. The corrugated board packaging material 300 has a seventh fold line 336 (support fold line) at the boundary between the fourth connection part 303 and the seventh connection part 335 . The corrugated board packaging material 300 also includes a seventh connection portion 385 that is connected to the support portion of the fourth connection portion 304 . The seventh connecting portion 385 is, for example, rectangular. The corrugated board packaging material 300 has a seventh fold line 386 (support fold line) at the boundary between the fourth connecting portion 304 and the seventh connecting portion 385 .

The first folding lines 311 and 361, the second folding lines 312 and 362, the third folding lines 313 and 363, the fourth folding lines 314 and 364, the first insertion portions 307 and 357, and the third openings 308, 309, 358 and 359 are the same as in the specific state. Sample 1. ＜Assembly of corrugated board packaging materials＞

The assembly of corrugated board packaging material 300 will be described with reference to Figure 8B. The folding of the first connecting part 302a, the second connecting part 302b, and the third connecting part 302c is the same as in the specific aspect 1. In the corrugated board packaging material 300, the first closed loop is formed by the base part 301, the first connecting part 302a, the second connecting part 302b, and the third connecting part 302c. The first closed loop formed by the base part 301 and the first receiving part 302 therefore has three folds. The first connection part 352a, the second connection part 352b, and the third connection part 352c are also folded in the same manner as the first connection part 302a, the second connection part 302b, and the third connection part 302c. In the corrugated board packaging material 300, the second closed loop is formed by the base part 301, the first connecting part 352a, the second connecting part 352b, and the third connecting part 352c. The second closed loop formed by the base 301 and the first receiving portion 352 therefore has three folds. As shown in FIG. 8B , the corrugated board packaging material 300 has two approximately rectangular closed loops.

The sixth connecting part 331 is folded to the first connecting part 302a at the sixth folding line 332 from the back of the corrugated board toward the front of the corrugated board. In this way, the sixth folding part is formed between the first connecting part 302a and the sixth connecting part 331. The fifth connecting part 333 is folded to the second connecting part 302b at the fifth folding line 334 from the back of the corrugated board toward the front of the corrugated board. In this way, the fifth folded part is formed between the second connecting part 302b and the fifth connecting part 333. When the sixth connecting part 331 is inserted into the groove of the fifth connecting part 333 , the sixth connecting part 331 is engaged with the fifth connecting part 333 . Taking the sixth fold line 332 as a reference, the sixth connecting part 331 has a first part with a first height and a second part with a second height. The first height is higher than the second height. The first part of the sixth connecting part 331 may be inserted into the groove of the fifth connecting part 333 . By the sixth connecting portion 331 being joined to the fifth connecting portion 333 , the sixth connecting portion 331 is maintained in a state of being perpendicular or approximately perpendicular to the back surface of the base 301 . Since the corrugated board packaging material 300 has the sixth connection portion 331, when the corrugated board packaging material 300 is attached to the box P, the cross-sectional area of the corrugated board supporting the box P is increased; as a result, the box P can be protected from vibration and impact.

The sixth connecting part 381 is folded to the first connecting part 352a at the sixth folding line 382 from the back of the corrugated board toward the front of the corrugated board. In this way, the sixth folding part is formed between the first connecting part 352a and the sixth connecting part 381. When the third insertion portion 381a of the sixth connection portion 381 is inserted into the first opening 305, the sixth connection portion 381 is engaged with the base portion 301. Since the corrugated board has a certain thickness in the third insertion portion 381a, the third insertion portion 381a can be inserted into the first opening 305. If the folding angle of the first connecting part 352a to the base part 301 is at an acute angle, the third insertion part 381a may be inserted into the first opening 305.

The fifth connecting part 383 is folded to the second connecting part 352b at the fifth folding line 384 from the back of the corrugated board toward the front of the corrugated board. In this way, the fifth folded part is formed between the second connecting part 352b and the fifth connecting part 383. When the fifth connecting part 383 is folded in a state where the sixth connecting part 381 is joined to the base part 301 , the corrugated board supports the sixth connecting part 381 at the cross section of the fifth connecting part 383 . Therefore, the sixth connecting portion 381 prevents the sixth connecting portion 381 from being displaced when the sixth connecting portion 381 is joined to the base portion 301 . By the sixth connecting part 381 being joined to the base part 301 , the sixth connecting part 381 is maintained in a vertical or approximately perpendicular state to the back surface of the base part 301 . Since the corrugated board packaging material 300 has the sixth connection portion 381, when the corrugated board packaging material 300 is attached to the box P, the cross-sectional area of the corrugated board supporting the box P is increased; as a result, the box P can be protected from vibration and impact.

The sixth connection part 331 may include an insertion part (third insertion part) similar to the third insertion part 381a. By inserting the third insertion portion of the sixth connecting portion 331 into the first opening 305 , the sixth connecting portion 331 may be joined to the base portion 301 . The fifth connection portion 383 may include a groove similar to the groove of the fifth connection portion 333 . By inserting the sixth connecting part 381 into the groove of the fifth connecting part 383 , the sixth connecting part 381 may be joined to the fifth connecting part 383 .

The seventh connecting part 335 is folded to the fourth connecting part 303 at the seventh fold line 336 from the back of the corrugated board toward the front of the corrugated board. In this way, the seventh folded part is formed between the fourth connecting part 303 and the seventh connecting part 335 . The seventh connecting portion 385 is also folded to the fourth connecting portion 304 at the seventh fold line 386 from the back of the corrugated board toward the front of the corrugated board. In this way, the seventh folded portion is formed between the fourth connecting portion 304 and the seventh connecting portion 385 . The seventh connecting portions 335 and 385 are configured to be perpendicular or approximately perpendicular to the back surface of the base 301 . Since the corrugated board packaging material 300 has the seventh connection parts 335 and 385, when the corrugated board packaging material 300 is attached to the box P, the cross-sectional area of the corrugated board supporting the box P is increased; as a result, the box P can be protected from vibration and impact.

As illustrated in Figure 8B, the second insertion portion 303b is inserted into the third opening 308 from outside the first closed loop, and the second insertion portion 304b is inserted into the third opening 309 from outside the first closed loop. When the first closed loop is opened, since the third connection part 302c moves in the direction close to the fourth connection parts 303 and 304, the movement of the third connection part 302c can be regulated by the fourth connection parts 303 and 304, that is, Like concrete form 1.

<Assembly of corrugated board packaging materials>

The assembly of corrugated board packaging material 400 will be described with reference to Figure 9B. The first connecting portion 402a is folded to the base 401 from the back of the corrugated board toward the front of the corrugated board at the first fold line 411, so that the first folded portion is formed between the base 401 and the first connecting portion 402a. The second connecting part 402b is folded to the first connecting part 402a at the second folding line 412 from the back of the corrugated board toward the front of the corrugated board, so that the second folded part is formed between the first connecting part 402a and the second connecting part 402b. The third connecting part 402c is folded to the second connecting part 402b from the back of the corrugated board toward the front of the corrugated board at the third fold line 413. In this way, the third connecting part 402c is folded to the second connecting part 402b. A three-fold portion is formed between the second connection portion 402b and the third connection portion 402c.

In the corrugated board packaging material 400, the first closed loop is formed by the base part 401, the first connecting part 402a, the second connecting part 402b, and the third connecting part 402c. The first closed loop formed by the base part 401 and the first receiving part 402 therefore has three folds. The first connection part 452a, the second connection part 452b, and the third connection part 452c are also folded in the same manner as the first connection part 402a, the second connection part 402b, and the third connection part 402c. In the corrugated board packaging material 400, the second closed loop is formed by the base part 401, the first connecting part 452a, the second connecting part 452b, and the third connecting part 452c. The second closed loop formed by the base 401 and the first receiving portion 452 therefore has three folds. As shown in FIG. 9B , the corrugated board packaging material 400 includes two approximately rectangular closed loops.

When the first closed loop is formed by the base part 401 and the first receiving part 402, and each first insertion part 407 is inserted into each corresponding first opening 405, the first receiving part 402 is engaged with the base part 401. When the second closed loop is formed by the base portion 401 and the second receiving portion 452, and each insertion portion 457 is inserted into each corresponding first opening 405, the second receiving portion 452 is engaged with the base portion 401.

The fourth connecting part 403 is folded to the base 401 from the back of the corrugated board toward the front of the corrugated board at the fourth folding line 423 , so that the fourth folded part is formed between the base 401 and the fourth connecting part 403 . The fourth connecting part 404 is folded to the base 401 from the back of the corrugated board toward the front of the corrugated board at the fourth folding line 424 , so that the fourth folded part is formed between the base 401 and the fourth connecting part 404 . When the second insertion parts 403a and 404a are inserted into the third openings 408 and 409 respectively, the second insertion parts 403a and 404a are engaged with the third connection part 402c. The second insertion portions 403a and 404a are engaged with the third connecting portion 402c, thus preventing the first closed loop from opening. When the second insertion parts 453a and 454a are inserted into the third openings 458 and 459 respectively, the second insertion parts 403a and 404a are engaged with the third connection part 452c. The second insertion portions 453a and 454a are engaged with the third connecting portion 452c, thus preventing the second closed loop from opening.

As illustrated in FIG. 9B , the second insertion portion 403a is inserted into the third opening 408 from inside the first closed loop, and the second insertion portion 404a is inserted into the third opening 409 from inside the first closed loop. By inserting each first insertion portion 407 into each first opening 405, the movement of the third connecting portion 402c can be controlled, so that the first closed loop does not open. When the second insertion parts 403a and 404a are inserted into the third openings 408 and 409 respectively, each first insertion part 407 is adjusted so as not to be separated from each first opening 405. In this way, each first insertion portion 407 is inserted into each first opening 405, thereby regulating the movement of the third connecting portion 402c toward the outside of the first closed loop. Furthermore, the second insertion parts 403a and 404a are adjusted so that each first insertion part 407 is not separated from each first opening 405. That is, the second insertion portions 403a and 404a regulate the separation of each first insertion portion 407 and each first opening 405. The structures and effects of the second insertion portions 453a and 454a are respectively the same as those of the second insertion portions 403a and 404a. The structure and effects of each first insertion portion 457 are the same as those of each first insertion portion 407 .

The corrugated board packaging material 400 includes a first protrusion 491 disposed in the first folding part and a second protrusion 492 disposed in the second folding part. The first protruding portion 491 protrudes from at least one of the base portion 401 and the first connecting portion 402a in a direction intersecting the direction in which the first fold line 411 extends. The second protruding portion 492 protrudes from at least one of the first connecting portion 402a and the second connecting portion 402b in a direction intersecting the direction in which the second fold line 412 extends.

The corrugated board packaging material 400 includes third protrusions 414, 417 disposed in the first folding part and third protrusions 415, 416, 418, 419 disposed in the third folding part. The third protrusions 414 to 419 protrude in the direction in which the first fold line 411 , the second fold line 412 , and the third fold line 413 extend. The structure of the corrugated board packaging material is not limited to this structure, but for example, it may cause the third protrusions 414 and 417 to be disposed in the first folding part, the third protrusions 415 and 418 to be disposed in the second folding part, and the third protrusion 417 to be disposed in the second folding part. Parts 416 and 419 are arranged in the third folding part. Furthermore, at least one of the third protruding parts 414 to 419 may be configured in at least one of the first folding part, the second folding part, and the third folding part.

When the first connecting portion 402a is folded at the first fold line 411, the first protruding portion 491 protrudes toward the outside of the corrugated board packaging material 400. When the second connecting portion 402b is folded at the second fold line 412, the second protruding portion 492 protrudes toward the outside of the corrugated board packaging material 400. The third protrusions 414 to 419 protrude toward the outside of the corrugated board packaging material 400 . When vibration or impact is applied to the corrugated board packaging material 400 , the first protruding portion 491 , the second protruding portion 492 , and the third protruding portions 414 to 419 are crushed, thereby alleviating the impact on the corrugated board packaging material 400 . As a result, when shock or impact is applied, it is possible to prevent the folded portion of the corrugated board packaging material 400 from returning to the previous state before folding and allowing the corrugated board packaging material 400 to spread. Furthermore, since the deformation of the corrugated board packaging material 400 caused by vibration or impact is concentrated on the first protruding portion 491, the second protruding portion 492, and the third protruding portions 414 to 419, the direct deformation of the corrugated board packaging material 400 can be reduced. Deformation of the part contacting the box P. As a result, shaking between the corrugated board packaging material 400 and the box P can be avoided.

The structures and effects of the first protruding part 493 and the second protruding part 494 are respectively the same as the structures and effects of the first protruding part 491 and the second protruding part 492. The structures and effects of the third protrusions 464 to 469 are the same as those of the third protrusions 414 to 419 . The first protrusions 491 and 493, the second protrusions 492 and 494, the third protrusions 414 to 419 and 464 to 469 of the specific aspect 4 may be applied to the specific aspects 1 to 3. ＜＜Specific form 5＞＞

Another specific aspect of the present invention will be described as specific aspect 5. The difference between the specific aspect 1 and the specific aspect 5 will be described below, and the description of the redundant content of the specific aspect 1 will be omitted.

The direction along the surface of the corrugated board (the direction perpendicular to the thickness direction of the corrugated board) and the direction in which the corrugated convex inner sheets are arranged is called the flow direction of the corrugated board. The direction along the surface of the corrugated board and perpendicular to the flow direction (the same as the generatrix direction of the corrugated protrusions) is called the width direction of the corrugated board. The direction intersecting the direction in which the first fold line 111 , the second fold line 112 , and the third fold line 113 extend in the corrugated board packaging material 100A is the width direction of the corrugated board during the manufacturing step (not shown). For corrugated boards, the strength of folded corrugated boards in the width direction is stronger than the strength of folded corrugated boards in the flow direction. Therefore, it is possible to avoid deformation of the first insertion portion 107 inserted into the first opening 105 and to prevent the engagement state of the base portion 101 and the third connection portion 102c from being released. The structure and effects of the first insertion part 157 are the same as those of the first insertion part 107 . Specific aspect 5 can be applied to specific aspects 1 to 4.

According to the present invention, there is provided a packaging member that is easy to assemble and prevents the folded portion of the packaging member from returning to a pre-folding state when shock or impact is applied.
