The first to fourth cartridges P (PY, PM, PC, PK) each include a similar electrophotographic process mechanism that processes different color developers (hereinafter referred to as toners). The first to fourth cartridges P (PY, PM, PC, PK) respectively store yellow (Y), magenta (M), cyan (C), and black (K) toners, respectively.

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

As exemplified 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), which includes a charging unit (which acts on the photosensitive drum) 4 on the processing unit) and cleaning unit. Further, the cartridge P includes a developing device 9 (second unit), which includes a developing unit to develop the electrostatic latent image on the photosensitive drum 4. The drum unit 8 and the developing device 9 are alternately connected. 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 structure of cassette P will be described later.

As shown 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 driver roller 13, a support roller 14, and a tension roller 15, and the elastic transfer belt 12 is stretched. The lower surface of the photosensitive drum 4 contacts the upper surface of the transfer belt 12.

4A and 4B are perspective views of the cassette P according to the specific aspect 1 when viewed from different angles. FIG. 4A is a perspective view when the cassette P is viewed from the driving side. FIG. 4B is a perspective view when the cassette 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 center of the hub of the developing device 9 as the center (the dotted line in FIG. 4A).

As exemplified in FIG. 3A, the drum unit 8 includes a drum frame 26, which includes a photosensitive drum 4, a charging roller 5, and a cleaning blade 7. As exemplified in FIGS. 4A and 4B, the photosensitive drum 4 is rotatably supported by the driving side support member 24 and the driven side support member 25. The driving side support member 24 and the driven side support member 25 may be regarded as parts of the drum frame 26. After receiving the driving force of the motor (not shown) of the device 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 exemplified in FIG. 3A, both ends of the charging roller 5 are rotatably supported by the charging roller 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 uniformly charge the surface of the photosensitive drum 4, both ends of the charging roller 5 are pressed against the surface of the photosensitive drum 4 by a charging roller pressure spring 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 a direction opposite to the rotation direction of the photosensitive drum 4 (the arrow D direction in FIG. 3A). When an image is formed, the cleaning blade 7 scrapes off the remaining untransferred toner on the photosensitive drum 4 so as to clean the surface of the photosensitive drum 4. The untransferred toner scraped off by the cleaning blade 7 from the surface of the photosensitive drum 4 is stored in the waste toner storage portion 26a of the drum frame 26 as waste toner.

As exemplified in FIGS. 3A and 7, the developing device 9 is a horizontally elongated developing unit that extends 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 exemplified 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 exemplified 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 Figure 7, the two shaft ends (core members) 6a of the developing roller 6 are rotatably supported by the driving side bearing 38 and the driven side bearing 39, which are respectively mounted on each side surface 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 feeding 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 feeding roller 33. The developing roller gear 40 and the feeding roller gear 41 are engaged with the developing drive input gear 42. The developing drive input gear 42 includes a developing drive coupling 42a. With the drive output coupler (not shown) that is coupled to the side of the device main body 2 of the developing drive coupler 42a, the driving force of the drive motor (not shown) of the device main body 2 is transferred to the developing drive input gear 42, and the image is developed. The roller 6 and the developer feeding roller 33 are rotationally driven at a predetermined speed.

The free end of the developing blade 31 in the shorter direction contacts the developing roller 6 in a direction opposite to the direction of rotation of the developing roller 6 (the arrow E direction in FIG. 3A). The developing device (developing unit) 9 takes the axis a (center of the hub) in FIG. 4A as the center, 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 FIG. 3A). Direction), and the developing roller 6 is in contact with the photosensitive drum 4. On the other hand, FIG. 3B indicates a state where the developing roller 6 is released from the photosensitive drum 4. When an image is formed, the developer feeding 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 provides the toner with the triboelectric charge generated by the contact pressure between the developing blade 31 and the developing roller 6. Then, the charged toner on the developing roller 6 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 unfolded state of the corrugated board packaging material 100A before assembly, and FIG. 1B is a diagram of the corrugated board packaging material 100A after assembly. FIG. 5 is an illustration of a state in which the cassette 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 cassette P. By attaching the corrugated board packaging material 100A and the corrugated board packaging material 100B to the cassette P, the cassette 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 cassette P is viewed from 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 29c and the center of the waste toner storage portion 26a in the longitudinal direction of the cassette P. The space of the waste toner storage portion 26a and the toner storage container 29c exists in the cartridge P in the center area in the longitudinal direction. Therefore, 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 and avoiding the central area of the cartridge P in the longitudinal direction, the 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 a direction perpendicular to the longitudinal direction of the box P, the corrugated board packaging material 100A and the packaging object (the box P, or the bag or sheet that encloses 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 cassette P from dust and the like, the cassette P may be covered by a bag or a sheet (not shown). The bag or sheet may be placed outside the cassette P and the corrugated board packaging material 100A and 100B, or may be placed between the cassette P and the corrugated board packaging material 100A and between the cassette P and the corrugated board packaging material 100B. The box P attached to the corrugated board packaging materials 100A and 100B is inserted into the corrugated board box (not shown). In this case, the corrugated board packaging materials 100A and 100B can protect the box P from vibration and impact applied from the outside of the corrugated board box. ＜The 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 surface and a back surface, and is attached to the cassette 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.

The first receiving portion 102 of the receiving box P includes a first connecting portion 102a, a second connecting portion 102b, and a third connecting portion 102c. The first connecting portion 102a is connected to the base 101, the second connecting portion 102b is connected to the first connecting portion 102a, and the third connecting portion 102c is connected to the second connecting portion 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 connecting portion 102b and the third connecting portion 102c. The first fold line 111, the second fold line 112, and the third fold 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 cassette P. The second opening 106 is formed in the second connecting portion 102b and the third connecting portion 102c, and the second opening 106 is arranged to overlap with a line (not shown) connecting the third folding line 113a and the third folding line 113b. The third connecting portion 102c includes third openings 108 and 109, which are joint openings. The third connecting portion 102c also includes a first insertion portion 107 that protrudes from the corrugated board in a direction crossing 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 connecting portion 102c is arranged between the second opening 106 and the first insertion portion 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 folding line 113.

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

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

The fourth connecting portion 103 includes second inserting portions 103a and 103b as engaging portions, and the fourth connecting portion 104 includes second inserting portions 104a and 104b as engaging portions. The second insertion portions 103a, 103b, 104a, 104b each have a hook shape. In other words, the fourth connecting portion 103 includes second inserting portions 103a and 103b, which protrude in the direction in which the fourth fold line 114 extends; the fourth connecting portion 104 includes second inserting portions 104a and 104b, which are positioned on the fourth fold line 164. 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 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 the same for FIGS. 6A, 8A, and 9A mentioned later. ＜Assembly of corrugated board packaging materials＞

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

In the corrugated board packaging material 100A, the first closed loop is formed by the base 101, the first connecting portion 102a, the second connecting portion 102b, and the third connecting portion 102c. Therefore, the first closed loop formed by the base 101 and the first receiving portion 102 has three folds. The first connection portion 152a, the second connection portion 152b, and the third connection portion 152c are also folded in the same manner as the first connection portion 102a, the second connection portion 102b, and the third connection portion 102c. In the corrugated board packaging material 100A, the second closed loop is formed by the base 101, the first connecting portion 152a, the second connecting portion 152b, and the third connecting portion 152c. Therefore, the second closed loop formed by the base 101 and the first receiving portion 152 has three folds. As shown in FIG. 1B, the corrugated board packaging material 100A has two closed loops that are approximately rectangular. A closed loop refers to a shape (such as a circle, an ellipse) that matches the starting point and the end point, and for example, the shape includes a curve (the curvature of which is different from other regions), a triangle, a square, and the like.

When the first closed loop is formed by the base 101 and the first receiving portion 102, and the first insertion portion 107 is inserted into the first opening 105, the third connecting portion 102c is joined to the base 101. When the second closed loop is formed by the base 101 and the second receiving portion 152, and the first insertion portion 157 is inserted into the first opening 105, the third connecting portion 152c is joined to the base 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 portion 102 and the second opening 156 of the second receiving portion 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 portion 103 is folded to the base 101 at the fourth fold line 114 from the back of the corrugated board toward the front of the corrugated board, so that the fourth folded portion is formed between the base 101 and the fourth connecting portion 103. The fourth connecting portion 104 is folded to the base 101 at the fourth fold line 164 from the back of the corrugated board toward the front of the corrugated board, so that the fourth folded portion is formed between the base 101 and the fourth connecting portion 104. When the second insertion portions 103b and 104b are inserted into the third openings 108 and 109, respectively, the second insertion portions 103b and 104b are engaged with the third connection portion 102c. The second insertion portions 103b and 104b are joined to the third connecting portion 102c, so as to prevent the first closed loop from opening. When the second insertion portions 103a and 104a are inserted into the third openings 158 and 159, respectively, the second insertion portions 103a and 104a are engaged with the third connection portion 152c. The second insertion portions 103a and 104a are joined to the third connecting portion 152c, so as to prevent the second closed loop from opening.

As illustrated in FIG. 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 connecting portion 102c moves in a direction approaching the fourth connecting portions 103 and 104, the movement of the third connecting portion 102c can be controlled by the fourth connecting portions 103 and 104. As a result, it is possible to more surely avoid the opening of the first closed loop. 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 connecting portion 152c moves in a direction approaching the fourth connecting portions 103 and 104, the movement of the third connecting portion 152c can be controlled by the fourth connecting portions 103 and 104. As a result, the opening of the second closed loop can be avoided with greater certainty.

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

The first connecting portions 102a and 152a, the second connecting portions 102b and 152b, the third connecting portions 102c and 152c, and the fourth connecting portions 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 assembly of the corrugated board packaging material 100A is easy.

The opening direction of the closed loop formed by the base 101 and the first receiving portion 102 and the opening direction of the closed loop formed by the base 101 and the first receiving portion 152 are perpendicular or approximately perpendicular to the direction of the back of the base 101. Further, the direction of releasing the engagement state of the fourth connecting portion 103, 104 and the first receiving portion 102 and the direction of releasing the engagement state of the fourth connecting portion 103, 104 and the second receiving portion 152 are parallel or approximately parallel to the base portion The direction of the back of 101. Furthermore, the direction in which the engagement state between the fourth connecting portions 103 and 104 and the first receiving portion 102 is released is the direction in which the closed loop formed by the base 101 and the first receiving portion 102 becomes smaller. The direction in which the engagement state of the fourth connecting portions 103 and 104 and the second receiving portion 152 is released is the direction in which the closed loop formed by the base 101 and the second receiving portion 152 becomes smaller. The opening direction of the closed loop formed by the base portion 101 and the first receiving portion 102 is different from the direction in which the engagement state between the fourth connecting portions 103 and 104 and the first receiving portion 102 is released. Furthermore, the opening direction of the closed loop formed by the base 101 and the second receiving portion 152 is different from the direction in which the engagement state between the fourth connecting portions 103 and 104 and the second receiving portion 152 is released. As a result, when a shock or impact is applied, the folded portion of the corrugated board packaging material 100A can be prevented from returning to the previous state before folding and causing the corrugated board packaging material 100A to spread out.

The directions of the first fold lines 111, 161, the second fold lines 112, 162, and the third fold lines 113, 163 cross the directions of the fourth fold lines 114 and 164. Therefore, when a shock or an impact is applied, the fourth connecting portions 103 and 104 can receive force from the first receiving portion 102 and the second receiving portion 152 along the surface of the base 101. In other words, the fourth connecting portions 103 and 104 can receive the force for opening the first closed loop and the force for opening the second closed loop along the surface of the fourth connecting portions 103 and 104. The fourth connecting portions 103 and 104 are configured to extend in a direction perpendicular to each surface of the third connecting portions 102c and 152c. Therefore, even if the force along the surface of the base 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 are not deformed much. As a result, when vibration 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 cassette P contacts the cross-section of the corrugated board of the cassette P and the corrugated board packaging material 100A, and absorbs shock and impact by deforming the corrugated board in the direction pushing the corrugated board cross-section during transportation. The strength in the direction of the cross section of the corrugated board (the direction parallel to the surface of the sheet) is stronger than the direction of the surface (front and back) of the corrugated board (the direction perpendicular to the surface of the sheet). Therefore, the corrugated board packaging material 100A can absorb strong vibration and impact. First insertion portions 107 and 157, second insertion portions 103a, 103b, 104a and 104b, first opening 105, second openings 106 and 156, third openings 108, 109, 158 and 159, fourth connection portions 103 and 104 The number of each may be set appropriately as needed. Therefore, the respective numbers of these members and openings are not limited to FIGS. 1A and 1B. ＜＜Specific aspect 2＞＞

Like 1. ＜Assembly of corrugated board packaging materials＞

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

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

The sixth connecting portion 381 is folded to the first connecting portion 352a at the sixth fold line 382 from the back of the corrugated board toward the front of the corrugated board, so that the sixth folded portion is formed between the first connecting portion 352a and the sixth connecting portion 381. When the third insertion portion 381 a of the sixth connection portion 381 is inserted into the first opening 305, the sixth connection portion 381 is joined to the base 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 portion 352a to the base 301 is an acute angle, the third insertion portion 381a may be inserted into the first opening 305.

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

The sixth connecting portion 331 may include an insertion portion (third insertion portion), which is similar to the third insertion portion 381a. 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 301. The fifth connecting portion 383 may include a groove, which is similar to the groove of the fifth connecting portion 333. Inserting the sixth connecting portion 381 into the groove of the fifth connecting portion 383, the sixth connecting portion 381 may be joined to the fifth connecting portion 383.

The seventh connecting portion 335 is folded to the fourth connecting portion 303 at the seventh fold line 336 from the back of the corrugated board toward the front of the corrugated board, so that the seventh folding portion is formed between the fourth connecting portion 303 and the seventh connecting portion 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, so that the seventh folding portion is formed between the fourth connecting portion 304 and the seventh connecting portion 385. The seventh connecting portions 335 and 385 are arranged to be perpendicular or approximately perpendicular to the back surface of the base portion 301. Since the corrugated board packaging material 300 has the seventh connecting portions 335 and 385, when the corrugated board packaging material 300 is attached to the cassette P, the cross-sectional area of the corrugated board supporting cassette P increases; as a result, the cassette P can be protected from vibration and Shock.

As illustrated in FIG. 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.

For the corrugated board packaging material 400, the second closed loop is formed by the base 401, the first connecting portion 452a, the second connecting portion 452b, and the third connecting portion 452c. Therefore, the second closed loop formed by the base 401 and the first receiving portion 452 has three folded portions. 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 401 and the first receiving portion 402, and each first insertion portion 407 is inserted into each corresponding first opening 405, the first receiving portion 402 is joined to the base 401. When the second closed loop is formed by the base 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 joined to the base 401.

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

As shown in FIG. 9B, the second insertion portion 403a is inserted into the third opening 408 from the inside of the first closed loop, and the second insertion portion 404a is inserted into the third opening 409 from the inside of the first closed loop. Inserting each first insertion portion 407 into each first opening 405 can regulate the movement of the third connecting portion 402c, so that the first closed loop is not opened. The second insertion portions 403a and 404a are inserted into the third openings 408 and 409, respectively, and each first insertion portion 407 is regulated 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, so as to regulate the movement of the third connecting portion 402c toward the outside of the first closed loop. Furthermore, the second insertion portions 403a and 404a are regulated so that each first insertion portion 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 the same as those of the second insertion portions 403a and 404a, respectively. The structure and effect of each first insertion part 457 are the same as those of each first insertion part 407.

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

The corrugated board packaging material 400 includes third protrusions 414 and 417 arranged in the first folding part and third protrusions 415, 416, 418, and 419 arranged 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 arranged in the first folding part, the third protrusions 415 and 418 to be arranged in the second folding part, and the third protrusion The parts 416 and 419 are arranged in the third folding part. Furthermore, at least one of the third protrusions 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 on the first fold line 411, the first protrusion 491 protrudes toward the outside of the corrugated board packaging material 400. When the second connecting portion 402b is folded on the second folding line 412, the second protrusion 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 protrusion 491, the second protrusion portion 492, and the third protrusions 414 to 419 are crushed, thereby alleviating the impact on the corrugated board packaging material 400. As a result, when a shock or an impact is applied, the folded portion of the corrugated board packaging material 400 can be prevented from returning to the previous state before folding and allowing the corrugated board packaging material 400 to spread out. Furthermore, since the deformation of the corrugated board packaging material 400 caused by vibration or impact is concentrated on the first protrusion 491, the second protrusion portion 492, and the third protrusions 414 to 419, the direct impact of the corrugated board packaging material 400 can be reduced. Deformation of the part of the contact 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 protrusion 493 and the second protrusion 494 are the same as those of the first protrusion 491 and the second protrusion 492, respectively. 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, and the third protrusions 414 to 419 and 464 to 469 of the specific aspect 4 can be applied to the specific aspects 1 to 3. ＜＜Specific aspect 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 sheet (the direction perpendicular to the thickness direction of the corrugated board sheet) and the direction in which the corrugated convex inner sheet is arranged is called the flow direction of the corrugated board sheet. The direction along the surface of the corrugated board sheet and perpendicular to the flow direction (same as the direction of the generatrix of the corrugated protrusions) is called the width direction of the corrugated board sheet. 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 sheet in the manufacturing step (not shown). For the corrugated board, the strength of folding the corrugated board in the width direction is stronger than the strength of folding the corrugated board in the flow direction. Therefore, it is possible to prevent the first insertion portion 107 inserted into the first opening 105 from being deformed, and to prevent the engagement state of the base portion 101 and the third connecting portion 102c from being released. The structure and effect 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 the state before folding when vibration or impact is applied.
