[0007] Below, with reference to Figures 1 to 11, we will explain embodiments of a toner cartridge packaging box (hereinafter mainly referred to as a packaging box) 14, a toner cartridge circulation body (hereinafter mainly referred to as a circulation body) 10, and a toner cartridge packaging blank (hereinafter mainly referred to as a blank) 110.

[0008] As shown in FIGS. 1 to 3, a toner cartridge circulation product 10 includes a toner cartridge 12 and a toner cartridge packaging box 14.

[0009] The toner cartridge 12 shown in FIG. 1 is formed long along its longitudinal axis. The toner cartridge 12 is detachable from an image forming apparatus, such as a multifunction peripheral. When the toner cartridge 12 is attached to the image forming apparatus, it is inserted from the front side toward the rear side of the image forming apparatus. When the toner cartridge 12 is removed from the image forming apparatus, it is pulled out from the front side of the image forming apparatus.

[0010] The toner cartridge 12 has a cylindrical outer container 22 made of, for example, plastic material. A lid 24 is fixed to a first end (left side) 221 of the toner cartridge 12 shown in FIG. 1 . The lid 24 is welded to the outer container 22 after toner, which is a powder mixture of electrostatically charged fine particles and a pigment, is poured into the outer container 22. A gear 26 is provided at the first end (left side) 221 of the toner cartridge 12. A second end (right side) 222 of the toner cartridge 12 forms a closing portion of the outer container 22.

[0011] When the toner cartridge 12 is attached to the image forming device, the first end 221 of the toner cartridge 12 shown in FIG. 1 is positioned on the rear side of the image forming device, and the second end 222 of the toner cartridge 12 is positioned on the front side of the image forming device.

[0012] The packaging box 14 shown in Figures 4 to 6 is formed of a plate material such as double-sided corrugated cardboard. The packaging box 14 may be formed of paper corrugated cardboard or plastic corrugated cardboard. As an example, the interior dimensions of the packaging box 14 are 463 x 98 x 80 mm, and the exterior dimensions of the packaging box 14 are 500 x 107 x 89 mm. The packaging box 14 has a box-shaped storage section 32, a lid section 34, a first buffer section 36, and a second buffer section 38.

[0013] Here, the circulation object 10 has an X-axis, a Y-axis, and a Z-axis with respect to the toner cartridge 12 and the packaging box 14, as shown in Figures 1 to 3. The X-axis is a direction along the longitudinal direction of the toner cartridge 12 and the packaging box 14. The Y-axis is perpendicular to the X-axis, and is taken so that the XY plane is a plane parallel to the bottom surface of the bottom plate portion 40 of the packaging box 14. The Y-axis is a direction along the width direction perpendicular to the longitudinal direction. The Z-axis is perpendicular to the X-axis and Y-axis. The Z-axis is a direction along the height direction perpendicular to the longitudinal and width directions.

[0014] The storage section 32 is formed to a size that can store the toner cartridge 12. The storage section 32 has a bottom plate 40, a first side plate 41, a second side plate 42, a third side plate 43, and a fourth side plate 44. The first side plate 41 and the second side plate 42 are spaced apart in the width direction and face each other. The third side plate 43 and the fourth side plate 44 are spaced apart in the longitudinal direction and face each other.

[0015] 1, the surface of the first side plate 41 parallel to the ZX plane on the -Y-axis side of the storage section 32 of the packaging box 14 is the front surface, and the surface of the second side plate 42 parallel to the ZX plane on the +Y-axis side is the back surface. Also, the surface of the third side plate 43 parallel to the YZ plane on the -X-axis side of the storage section 32 is the left side surface, and the surface of the fourth side plate 44 parallel to the YZ plane on the +X-axis side is the right side surface.

[0016] The lid portion 34 has a lid top plate 51 and a lid flap 52.

[0017] The first buffer section 36 is provided, for example, on the third side plate section 43. Therefore, it is preferable that the first buffer section 36 is provided integrally with one end in the longitudinal direction of the storage section 32. The first buffer section 36 is formed to a size that allows the first end 221 of the toner cartridge 12 to fit therein.

[0018] The second buffer section 38 is provided, for example, on the fourth side plate section 44. Therefore, it is preferable that the second buffer section 38 is provided integrally with the other longitudinal end of the accommodating section 32. The second buffer section 38 supports the second end 222 of the toner cartridge 12. Therefore, the toner cartridge 12 is formed to have a size that allows it to be placed inside the accommodating section 32 when, for example, the first end 221 is supported by the first buffer section 36 and the second end 222 is supported by the second buffer section 38.

[0019] Before being assembled into the packaging box 14 shown in FIGS. 4 to 6, the blank 110 is formed into a flat plate having a thickness of, for example, 3 mm.

[0020] As shown in Figure 7, the blank 110 has a bottom portion 111, a first side panel region 112, a second side panel region 113, a lid portion 114, a lid flap portion 115, a first inner panel portion 116, a second inner panel portion 117, a first outer panel portion 118, a first bottom abutment portion 119, a first spacer portion (buffer area forming portion) 120, an engaging portion 121, a second spacer portion (buffer area forming portion) 122, a second outer panel portion 123, a second bottom abutment portion 124, a buffer area forming portion 125, and a fixing plate 126.

[0021] The bottom portion 111, the first side plate region 112, the second side plate region 113, the lid portion 114, the first outer plate portion 118, the first spacer portion 120, the fitting portion 121, the second spacer portion 122, and the second outer plate portion 123 are formed in an approximately rectangular shape.

[0022] The X-axis is taken in the longitudinal direction of the bottom 111 of the blank 110, and the Y-axis is taken in the direction perpendicular to the longitudinal direction. Therefore, the XY plane is taken to be a plane parallel to the front and back surfaces of the bottom 111 of the blank 110. The Z-axis is taken in the thickness direction of the blank 110.

[0023] A crease 131 (one long side of the bottom 111) is formed at the boundary between the bottom 111 and the first side panel region 112. A crease 132 (the other long side of the bottom 111) is formed at the boundary between the bottom 111 and the second side panel region 113. A crease 133 (lid crease) is formed at the boundary between the second side panel region 113 and the lid 114. A crease 134 (lid flap crease) is formed at the boundary between the lid 114 and the lid flap 115. A crease 135 (one short side of the first side panel region 112) is formed at the boundary between the first side panel region 112 and the first inner panel 116. A crease 136 (the other short side of the first side panel region 112) is formed at the boundary between the first side panel region 112 and the second inner panel 117. A crease 137 (on one short side of the second side plate region 113) is formed at the boundary between the second side plate region 113 and the first outer plate portion 118. A crease 138 is formed at the boundary between the first outer plate portion 118 and the first bottom abutment portion 119. A crease 139 is formed at the boundary between the first outer plate portion 118 and the first spacer portion 120. A crease 140 is formed at the boundary between the first spacer portion 120 and the fitting portion 121. A crease 141 is formed at the boundary between the fitting portion 121 and the second spacer portion 122. A crease 142 (on the other short side of the second side plate region 113) is formed at the boundary between the second side plate region 113 and the second outer plate portion 123. A crease 143 is formed at the boundary between the second outer plate portion 123 and the second bottom abutment portion 124. A crease 144 is formed at the boundary between the second outer plate portion 123 and the buffer area forming portion 125. A crease 145 is formed at the boundary between the buffer area forming portion 125 and the fixing plate 126.

[0024] The crease 133 is formed at a position that makes the bottom plate 40 and the lid top plate 51 parallel when the lid top plate 51 is folded relative to the storage section 32.

[0025] The line 134 is formed at a position where, when the lid flap 52 is folded against the lid top plate 51, the lid flap 52 abuts against the outer surface of the first side plate portion 41 and the lid flap 52 and the first side plate portion 41 are parallel to each other.

[0026] The length (widthwise length) of lid portion 114 along the Y-axis perpendicular to the longitudinal direction is longer than the length (widthwise length) of bottom portion 111 along the Y-axis perpendicular to the longitudinal direction. Therefore, when lid portion 114 is folded relative to bottom portion 111 along crease 131 and crease 132, and the first side plate region 112 and the second side plate region 113 are brought into a parallel state, lid portion 114 abuts against protrusion 1121 of first side plate region 112.

[0027] The edge of the first side plate region 112 on the -Y axis side (opposite the bottom 111 and the ruled line 131) is formed as a protruding portion 1121 that protrudes toward the -Y axis side (opposite the bottom 111) relative to an edge (first edge) 1162 on the -Y axis side of the first inner plate portion 116 and an edge (second edge) 1172 on the -Y axis side of the second inner plate portion 117. In other words, the edge 1162 of the first inner plate portion 116 is located closer to the bottom 111 (toward the +Y axis) than the protruding portion 1121 of the first side plate region 112. The edge 1172 of the second inner plate portion 117 is located closer to the bottom 111 (toward the +Y axis) than the protruding portion 1121 of the first side plate region 112. The protruding portion 1121 of the first side plate region 112 protrudes, for example, 3 mm toward the -Y axis side relative to the -Y axis side edge 1162 of the first inner plate portion 116 and the -Y axis side edge 1172 of the second inner plate portion 117.

[0028] The ruled line (one of the long edges) 133 and the protruding portion (the other long edge) 1121 of the first side plate region 112 form a pair of long edges of the opening of the storage section 32.

[0029] The first side plate region 112 has a corner 11211 formed as an inclined surface that slopes toward the -Y-axis side as it approaches the +X-axis side, between an edge 1162 of the first inner plate portion 116 and the protruding portion 1121 of the first side plate region 112. The first side plate region 112 has a corner 11212 formed as an inclined surface that slopes toward the +Y-axis side as it approaches the +X-axis side, between an edge 1172 of the second inner plate portion 117 and the protruding portion 1121 of the first side plate region 112.

[0030] The longitudinal length of the second side plate region 113 along the X-axis is shorter than the longitudinal length of the bottom portion 111. The longitudinal length of the second side plate region 113 is shorter than the longitudinal length of the lid portion 114 by, for example, about 1 mm to 2 mm. The length of the second side plate region 113 along the Y-axis perpendicular to the longitudinal direction is shorter than that of the first side plate region 112.

[0031] A through cut 1141 is formed between the lid portion 114 and the first spacer portion 120 and the fitting portion 121. A through cut 1142 is formed between the lid portion 114 and the buffer area forming portion 125 and the fixing plate 126.

[0032] A through cut 1151 is formed between the lid flap portion 115 and the fitting portion 121. The through cut 1151 is continuous with the through cut 1141. An inclined end 1152 that is spaced apart from the fitting portion 121 is formed on the +Y-axis side of the through cut 1151. The inclined end 1152 is inclined in the direction away from the +X-axis direction as it moves from the +X-axis side edge 1212 of the fitting portion 121 in the +Y-axis direction.

[0033] The lid flap portion 115 has a through cut 1151 and an inclined edge 1152 on its edge on the -X axis side. The lid flap portion 115 has an edge 1153 that is symmetrical to the through cut 1151 and the inclined edge 1152 on its edge on the +X axis side.

[0034] The lid flap portion 115 has an edge 1154 on the +Y-axis side. The longitudinal length of the edge 1154 along the X-axis is shorter than the longitudinal lengths of the lid portion 114 and the first side panel region 112. Furthermore, the length of the lid flap portion 115 in the Y-axis direction, which is perpendicular to the X-axis direction (longitudinal direction), i.e., the distance between the ruled line 134 and the edge 1154 of the lid flap portion 115 in the +Y-axis direction, is shorter than the distance between the ruled line 131 and the protruding portion 1121 of the first side panel region 112.

[0035] This prevents the +Y-axis direction edge 1154 of the lid flap portion 115 from being positioned lower than the bottom plate portion 40. Also, the +Y-axis direction edge 1154 of the lid flap portion 115 is prevented from being positioned on the -X-axis side beyond the third side plate portion 43, and from being positioned on the +X-axis side beyond the fourth side plate portion 44.

[0036] The longitudinal lengths of the bottom 111, the first side plate region 112, the second side plate region 113, and the lid portion 114 are longer than the overall length of the toner cartridge 12. The width lengths of the bottom 111 and the lid portion 114 along the Y-axis direction perpendicular to the longitudinal direction are longer than the width of the toner cartridge 12. The heights of the first side plate region 112 and the second side plate region 113 along the Y-axis direction perpendicular to the longitudinal direction are longer than the height of the toner cartridge 12 in the height direction perpendicular to the longitudinal and width directions.

[0037] The longitudinal length of the first side plate region 112 is shorter than the longitudinal length of the bottom 111. An edge 1161 on the +Y-axis side (bottom 111 side) of the first inner plate portion 116 is located more distant toward the -Y-axis side than the bottom 111 and the crease 131. Therefore, a first groove 161 is formed between the bottom 111, the first side plate region 112, and the first inner plate portion 116. An edge 1171 on the +Y-axis side (bottom 111 side) of the second inner plate portion 117 is located more distant toward the -Y-axis side than the bottom 111 and the crease 131. Therefore, a second groove 162 is formed between the bottom 111, the first side plate region 112, and the second inner plate portion 117.

[0038] The crease 138 on the bottom 111 side of the first outer plate portion 118 is spaced away from the crease 132 at the boundary between the bottom 111 and the second side plate region 113 toward the +Y axis.

[0039] A first bottom abutment portion 119 is formed on the -Y-axis side of the first outer plate portion 118. An edge 1191 on the +X-axis side of the first bottom abutment portion 119 is inclined and spaced away from the bottom portion 111 toward the -X-axis side. The edge 1191 is formed as an inclined end that inclines in the -X-axis direction as it moves from the +Y-axis side to the -Y-axis side. An edge 1192 on the -X-axis side of the first bottom abutment portion 119 has an inclined end 11921 that inclines in the -X-axis direction as it moves from the +Y-axis side to the -Y-axis side, and a straight edge 11922 that is straight along the -Y-axis direction from the -Y-axis side end of the inclined end 11921.

[0040] The crease 139 is located on the −Y axis side of the crease 133 between the second side panel region 113 and the lid portion 114.

[0041] A first spacer portion 120 is formed on the +Y-axis side (lid portion 114 side) of first outer plate portion 118. A fitting portion 121 is formed on the +Y-axis side of first spacer portion 120. A second spacer portion 122 is formed on the +Y-axis side of fitting portion 121.

[0042] The first spacer portion 120 forms a region between the creases 139 and 140 that has a length in the Y-axis direction that is at least several times longer than the thickness of the cardboard. The length (height) of the fitting portion 121 in the Y-axis direction is shorter than the lengths (heights) of the first side panel region 112 and the second side panel region 113 along the Y-axis direction between the creases 140 and 141. The length in the Y-axis direction between the creases 141 and the edge 1221 on the +Y-axis side of the second spacer portion 122 is shorter than the length in the Y-axis direction between the creases 139 and 140, for example, by the thickness of the cardboard.

[0043] The first spacer portion 120 and the lines 139 and 140 form one of a pair of short edges of the opening of the storage portion 32.

[0044] The fitting portion 121 has a first through-cut 151, a second through-cut 152, a third through-cut 153, a fourth through-cut 154, and a fifth through-cut 155. The first through-cut 151, the second through-cut 152, the third through-cut 153, the fourth through-cut 154, and the fifth through-cut 155 penetrate in the Z-axis direction.

[0045] The first through-slit 151 extends along the ruled line 141. The -X side end of the first through-slit 151 is spaced away from the -X-axis side edge 1211 of the fitting portion 121 on the +X-axis side. The +X side end of the first through-slit 151 is spaced away from the +X-axis side edge 1212 of the fitting portion 121 on the -X-axis side.

[0046] The second through cut 152 is spaced apart on the -Y-axis side from the first through cut 151 and extends in the X-axis direction. Therefore, the first through cut 151 and the second through cut 152 are parallel to each other. The -X-side end of the second through cut 152 is spaced apart on the +X-axis side from the -X-axis side edge 1211 of the fitting portion 121. The +X-side end of the second through cut 152 is spaced apart on the -X-axis side from the +X-axis side edge 1212 of the fitting portion 121.

[0047] The distance along the X axis between the −X side end of the first through cut 151 and the −X-axis side edge 1211 of the fitting portion 121 is set to be the same as the distance along the X axis between the −X side end of the second through cut 152 and the −X-axis side edge 1211 of the fitting portion 121. The distance along the X axis between the +X side end of the first through cut 151 and the +X-axis side edge 1212 of the fitting portion 121 is set to be the same as the distance along the X axis between the +X side end of the second through cut 152 and the +X-axis side edge 1212 of the fitting portion 121.

[0048] The third through-slit 153 connects approximately the center between the -X side end and the +X side end of the first through-slit 151 and approximately the center between the -X side end and the +X side end of the second through-slit 152. The third through-slit 153 preferably extends along the Y-axis.

[0049] The fourth through-slit 154 extends from the -X-axis side end of the second through-slit 152 toward the -Y-axis side. The -Y-axis side end of the fourth through-slit 154 is located so as not to reach the crease 140. The fifth through-slit 155 extends from the +X-axis side end of the second through-slit 152 toward the -Y-axis side. The -Y-axis side end of the fifth through-slit 155 is located so as not to reach the crease 140.

[0050] Note that ruled lines 146 and 147 are formed in the fitting portion 121 along the Y-axis direction. Ruled line 146 is spaced apart in the +X-axis direction from a -X-axis side edge 1211 of the fitting portion 121. Ruled line 146 is formed at a position connecting the -X-axis side end of first through-slit 151 and the -X-axis side end of second through-slit 152. Ruled line 147 is spaced apart on the +X-axis side from ruled line 146. Ruled line 147 is spaced apart on the -X-axis side from a +X-axis side edge 1212 of the fitting portion 121. Ruled line 147 is formed at a position connecting the +X-axis side end of first through-slit 151 and the +X-axis side end of second through-slit 152.

[0051] A crease 148 extending along the Y-axis direction is formed between the crease 146 and the third through-slit 153. A crease 149 extending along the Y-axis direction is formed between the crease 147 and the third through-slit 153.

[0052] The fitting portion 121 forms a first buffer flap portion 1213 between the first through-slit 151, the second through-slit 152, and the third through-slit 153 and the crease 146. The fitting portion 121 forms a second buffer flap portion 1214 between the first through-slit 151, the second through-slit 152, and the third through-slit 153 and the crease 147.

[0053] A crease 150 is formed along the X-axis in the fitting portion 121. The crease 150 is formed at a position connecting the -Y-axis side end of the fourth through-slit 154 and the -Y-axis side end of the fifth through-slit 155. The fitting portion 121 forms a third buffer flap portion 1215 between the crease 150 and the second through-slit 152, the fourth through-slit 154, and the fifth through-slit 155.

[0054] The crease 143 on the bottom 111 side of the second outer plate portion 123 is located at a position spaced apart from the crease 132 at the boundary between the bottom 111 and the second side plate region 113 on the +Y-axis side.

[0055] A second bottom abutment portion 124 is formed on the -Y-axis side of the second outer plate portion 123. An edge 1241 on the -X-axis side of the second bottom abutment portion 124 is inclined and moves away from the bottom portion 111 toward the +X-axis side. Therefore, the edge 1241 is formed as an inclined end that inclines in the +X-axis direction as it moves from the +Y-axis side toward the -Y-axis side. An edge 1242 on the +X-axis side of the second bottom abutment portion 124 has an inclined end 12421 that inclines in the +X-axis direction as it moves from the +Y-axis side toward the -Y-axis side, and a straight edge 12422 that is straight along the -Y-axis direction from the -Y-axis side end of the inclined end 12421.

[0056] The second bottom contact portion 124 has a through hole 1243 on the −Y-axis side of the ruled line 143, to which the protrusion 1262 of the fixing plate 126 is fixed.

[0057] A buffer area forming portion 125 is formed on the +Y-axis side of second outer plate portion 123. A fixing plate 126 is formed on the +Y-axis side of buffer area forming portion 125. Crease 144 is located on the -Y-axis side of crease 133 at the boundary between second side plate portion 113 and lid portion 114. Buffer area forming portion 125 forms an area along the Y-axis direction between crease 144 and crease 145 that has a length equal to or longer than the thickness of the cardboard.

[0058] The buffer region forming portion 125 and the ruled lines 144 and 145 form the other of the pair of short edges of the opening of the storage portion 32.

[0059] The distance between the ruled line 145 and the edge 1261 on the +Y-axis side of the fixed plate 126 is shorter than the length (height) of the first side plate region 112 and the second side plate region 113 in the Y-axis direction.

[0060] The fixing plate 126 has a protrusion 1262 that protrudes toward the +Y-axis side from an edge 1261 on the +Y-axis side. The protrusion 1262 has a size and shape that fits into the through-hole 1243.

[0061] A notch 1131 is formed on the second side plate region 113 side at the boundary between the second side plate region 113, the lid portion 114, the first outer plate portion 118, and the first spacer portion 120. The notch 1131 continues to a through notch 1141. A notch 1132 is formed on the second side plate region 113 side at the boundary between the second side plate region 113, the lid portion 114, the second outer plate portion 123, and the buffer region forming portion 125. The notch 1132 continues to a through notch 1142.

[0062] Furthermore, a notch 1133 is formed on the second side plate region 113 side at the boundary between the second side plate region 113, the bottom portion 111, the second outer plate portion 123, and the second bottom abutment portion 124. The notch 1133 is continuous with an edge 1241 on the -X-axis side of the second bottom abutment portion 124.

[0063] The creases 131-150 of the blank 110 are the folding lines. It is preferable that, for example, folding grooves are formed in advance at the positions of the creases 131-150 to make folding easier.

[0064] The blank 110 shown in FIG. 7 is folded along the lines 131-150 to form the packaging box 14 shown in FIG.

[0065] The first side plate region 112 is bent relative to the bottom portion 111 by the grooves 161, 162 and the crease 131. The first inner plate portion 116 is bent relative to the first side plate region 112 by the grooves 161 and the crease 135. The second inner plate portion 117 is bent relative to the first side plate region 112 by the grooves 162 and the crease 136.

[0066] The lid portion 114 is bent relative to the second side plate region 113 by the cuts 1131 and 1132 and the crease 133. The first outer plate portion 118 and the first spacer portion 120 are also bent relative to the second side plate region 113 by the cuts 1131 and the crease 137.

[0067] The second outer plate portion 123, the second bottom contact portion 124, and the buffer area forming portion 125 are bent relative to the second side plate region 113 by the cuts 1132, 1133 and the crease 142.

[0068] The first outer plate portion 118 is the plate closest to the -X axis of the third side plate portion 43 of the packaging box 14. The first inner plate portion 116 is disposed between the first outer plate portion 118 and the fitting portion 121. The first inner plate portion 116 comes into contact with the first outer plate portion 118 on the +X side, for example.

[0069] The first bottom abutment portion 119 is bent relative to the first outer plate portion 118 by the score line 138. As a result, the first bottom abutment portion 119 is placed on the bottom portion 111. At this time, the +X-axis side edge 1191 of the first bottom abutment portion 119 moves away from the second side plate region 113 toward the +X-axis side. The inclined end 11921 of the first bottom abutment portion 119 moves away from the first side plate region 112. The straight edge 11922 of the first bottom abutment portion 119 abuts against the first side plate region 112.

[0070] The first outer plate portion 118 and the fitting portion 121 are bent along creases 139 and 140, and are separated by the first spacer portion 120 between the creases 139 and 140. The second spacer portion 122 is also bent along crease 141 relative to the fitting portion 121. At this time, the first bottom abutment portion 119 and the second spacer portion 122 are overlapped with the bottom portion 111.

[0071] Then, the creases 146-149 of the fitting portion 121 are bent to bring the buffer flaps 1213, 1214 into contact with the first inner plate portion 116. The first spacer portion 120 is placed on the edge 1162 of the first inner plate portion 116. The creases 150 of the fitting portion 121 are also bent to place the third buffer flap portion 1215 at a distance from the first spacer portion 120 in the Z-axis direction. Therefore, the first buffer portion 36 is formed in the third side plate portion 43.

[0072] The second outer plate portion 123 is the plate closest to the +X axis side of the fourth side plate portion 44 of the packaging box 14. The second inner plate portion 117 is disposed between the second outer plate portion 123 and the fixing plate 126.

[0073] The second bottom abutment portion 124 is bent relative to the second outer plate portion 123 by the score line 143. As a result, the second bottom abutment portion 124 is placed on the bottom portion 111. At this time, the edge 1241 on the -X axis side of the second bottom abutment portion 124 moves away from the second side plate region 113 toward the -X axis side. The inclined end 12421 of the second bottom abutment portion 124 moves away from the first side plate region 112. The straight edge 12422 of the second bottom abutment portion 124 abuts against the first side plate region 112.

[0074] Then, by bending the lines 144, 145, the protrusions 1262 are inserted into the through holes 1243 and fixed. At this time, the fourth side plate 44 is formed by overlapping three plates: the second outer plate 123, the second inner plate 117, and the fixing plate 126. Furthermore, the buffer area forming portion 125 forms a space between the second outer plate 123 and the second inner plate 117, and between the second inner plate 117 and the fixing plate 126. Therefore, the second buffer portion 38 is formed in the fourth side plate 44. Furthermore, the storage portion 32 of the packaging box 14 is formed from the blank 110.

[0075] In this manner, the packaging box 14 having the storage section 32, the lid section 34, the first buffer section 36 and the second buffer section 38 is formed.

[0076] That is, the bottom portion 111, the first bottom abutment portion 119, the second spacer portion 122, and the second bottom abutment portion 124 correspond to the bottom plate portion 40 in the assembled state of the packaging box 14. The first side plate region 112 corresponds to the first side plate portion 41. The second side plate region 113 corresponds to the second side plate portion 42. The first outer plate portion 118 and the first inner plate portion 116 correspond to the third side plate portion 43. The first inner plate portion 116, the first bottom abutment portion 119, the first spacer portion 120, the fitting portion 121, and the second spacer portion 122 correspond to the first buffer portion 36. The second outer plate portion 123, the buffer area forming portion 125, and the fixing plate 126 correspond to the fourth side plate portion 44. The first inner plate portion 117, the second outer plate portion 123, the second bottom abutment portion 124, the buffer area forming portion 125, and the fixing plate 126 correspond to the second buffer portion 38. The lid portion 114 corresponds to the lid top plate 51. The lid flap portion 115 corresponds to the lid flap 52.

[0077] For example, the first bottom abutment portion 119 is formed as a part of the bottom plate portion 40, and is also formed as a part of the first buffer portion 36. In this way, a part of the blank 110 according to this embodiment can perform multiple functions even though it is a single member.

[0078] As shown in FIG. 4 , when the packaging box 14 is produced from the blank 110, the first spacer portion 120 is placed on the edge 1162 of the first inner plate portion 116. Therefore, the first spacer portion 120 sandwiches the first inner plate portion 116 between itself and the first outer plate portion 118, and the edge 1162 is sandwiched between itself and the lid portion 114. The thickness of the first spacer portion 120 and the amount of protrusion of the first side plate region 112 from the edge 1162 of the first inner plate portion 116 are the same. Therefore, in the packaging box 14, the first spacer portion 120 is flush with the protruding portion 1121 of the first side plate region 112.

[0079] Here, the upper end (opening) of the accommodating section 32 is formed into a rectangular shape by the protruding portion 1121 of the first side panel region 112, the first spacer portion 120, the ruled line 132, and the buffer area forming portion 125. Because the first spacer portion 120 forms the upper end of the first buffer portion 36, the first buffer portion 36 is accommodated within the accommodating section 32 without protruding above the upper end of the accommodating section 32. The first buffer portion 36 supports a first end 221 of the toner cartridge 12. The first end 221 of the toner cartridge 12 is fitted into the first buffer portion 36.

[0080] When the packaging box 14 is produced from the blank 110, the buffer area forming portion 125 is placed on the edge 1172 of the second inner plate portion 117. The thickness of the buffer area forming portion 125 and the amount of protrusion of the first side plate region 112 from the edge 1172 of the second inner plate portion 117 are the same. Therefore, in the packaging box 14, the buffer area forming portion 125 is flush with the protruding portion 1121 of the first side plate region 112. Therefore, the second buffer portion 38 is accommodated in the accommodating portion 32 without protruding above the upper end of the accommodating portion 32. The second buffer portion 38 supports the second end 222 of the toner cartridge 12.

[0081] Therefore, the three sides of the upper end of the accommodating section 32 of the packaging box 14 for the toner cartridge 12 are formed at the same height as the outer surface of the bottom plate 40. When the crease 133 at the boundary between the second side plate region 113 and the lid portion 114 is folded, the inner wall of the lid portion 114 abuts against the three sides of the upper end of the accommodating section 32. At this time, the second side plate region 113 is formed in a position where the bottom portion 111 and the lid portion 114 are parallel. Therefore, as shown in FIG. 8, simply folding along the crease 133 makes the bottom plate 40 and the lid top plate 51 parallel.

[0082] Here, if the height along the Y axis of the second side plate region 113 of the blank 110 is, for example, 86 mm and the height along the Y axis of the notch 1131 in the second side plate region 113 is 3 mm, the upper end surface of the first buffer section 36 and the protruding section 1121 of the first side plate region 112 will be flush or approximately flush with each other. If the height along the Y axis of the notch 1132 in the second side plate region 113 is 3 mm, the upper end surface of the second buffer section 38 and the protruding section 1121 of the first side plate region 112 will be flush or approximately flush with each other.

[0083] As shown in FIG. 9 , the first end 221 of the toner cartridge 12 is fitted into the first buffer section 36 of the accommodating section 32 of the packaging box 14, and the second end 222 of the toner cartridge 12 is brought close to the second buffer section 38. At this time, the longitudinal (left-right) length between the first end 221 and the second end 222 of the toner cartridge 12 falls within the range of the longitudinal distance between the third side plate section 43 and the fourth side plate section 44 of the accommodating section 32. For example, the first end 221 of the toner cartridge 12 penetrates the fitting section 121 but is separated from the first inner plate section 116. The first end 221 of the toner cartridge 12 is separated from the fixing plate 126. The vertical height of the first end 221 of the toner cartridge 12 falls within the vertical height range of the first buffer section 36. As shown in FIG. 10 , the width of the first end 221 of the toner cartridge 12 in the front-to-rear direction falls within the width of the first buffer section 36. As shown in FIGS. 9 and 11 , the vertical height of the second end 222 of the toner cartridge 12 falls within the vertical height range of the second buffer section 38. The width of the second end 222 of the toner cartridge 12 in the front-to-rear direction falls within the width of the second buffer section 38. Furthermore, at a position between the first end 221 and the second end 222 of the toner cartridge 12, the vertical height falls within the vertical height range of the accommodating section 32. At a position between the first end 221 and the second end 222 of the toner cartridge 12, the width of the toner cartridge 12 in the front-to-rear direction falls within the width of the accommodating section 32. Therefore, the toner cartridge 12 is accommodated in the accommodating section 32 without protruding outward.

[0084] 3 and 8, the storage section 32 is closed with the lid section 34. The crease 133 between the second side plate region 113 and the lid section 114 is folded, and the position of the lid section 34 on the lid flap section 115 side, which is closer to the crease 134, is brought into contact with the protrusion 1121 of the first side plate region 112. At this time, the outer surface of the bottom plate section 40 and the outer surface of the lid section 34 are parallel. That is, the distance (height) along the Z-axis direction between the outer surface of the bottom plate section 40 and the inner wall of the lid section 34 folded along the crease 133 is the same as the distance (height) along the Z-axis direction between the outer surface of the bottom plate section 40 and the protrusion 1121 of the first side plate region 112.

[0085] Therefore, in the packaging box 14, the lid top plate 51 (lid portion 114) contacts the protruding portion 1121 of the first side plate portion 41 (first side plate region 112), and the outer surface of the bottom plate portion 40 and the outer surface of the lid portion 34 are parallel (including approximately parallel) regardless of whether the lid flap 52 and the first side plate portion 41 are attached by, for example, gluing or the like. This makes it easy to position the lid flap 52 and the first side plate portion 41 in the packaging box 14. The toner cartridge circulation product 10 is transported to a desired location, for example, stacked one on top of the other, with the toner cartridges 12 housed in the toner cartridge packaging box 14 and the lid flap 52 fixed to the outer surface of the first side plate portion 41 on the front side of the toner cartridge packaging box 14.

[0086] Furthermore, in the region adjacent to the lid portion 114 (lid top plate 51), the region along the longitudinal direction between the region near the through cut 1151 and the inclined edge 1152 of the lid flap portion 115 (lid flap 51) and the region near the edge 1153 covers the corners 11211, 11212 spaced apart in the X-axis direction of the protruding portion 1121 of the first side plate region 112. Therefore, when the lid flap 52 of the packaging box 14 is fixed to the first side plate portion 41, the corners 11211, 11212 are hidden. Therefore, for example, when a distributor or the like holds the distribution item 10, the corners 11211, 11212 can be prevented from hitting the distributor's hand or the like.

[0087] 5 and 9, in the first buffer section 36, the bottom 111, the first bottom contact section 119, and the second spacer section 122 are stacked along the Z axis near the lower end of the storage section 32. Therefore, near the lower end of the storage section 32, the underside of the first end 221 of the toner cartridge 12 is supported by three cardboard sheets. Therefore, near the lower end of the storage section 32, the circulator 10 exhibits buffering properties against impacts from below along the Z axis of the third side plate section 43 of the circulator 10.

[0088] Furthermore, in the first buffer section 36, the third buffer flap section 1215 and the first spacer section 120 are arranged vertically spaced apart along the Z axis near the upper end of the accommodating section 32 along the Z axis. Therefore, the circulator 10 exhibits buffering properties against an impact from above along the Z axis of the third side plate section 43 of the circulator 10 near the upper end of the accommodating section 32. Furthermore, the circulator 10 forms a space into which the first end 221 of the toner cartridge 12 moves when the toner cartridge 12 moves upward in response to an impact from below along the Z axis of the third side plate section 43 of the circulator 10. Therefore, the circulator 10 exhibits buffering properties against an impact from above along the Z axis of the third side plate section 43 of the circulator 10 and an impact from below along the Z axis.

[0089] 5, 6, 9, and 10, the first buffering section 36 supports the first end 221 of the toner cartridge 12 along the X-axis direction relative to the first outer plate portion 118 by the first buffering flap portion 1213 and the second buffering flap portion 1214, spaced apart from the first end 221 of the toner cartridge 12 toward the +X-axis. Therefore, the circulator 10 exhibits buffering properties against impacts from the left side along the X-axis of the third side plate portion 43 of the circulator 10 near the left end portion of the accommodating section 32.

[0090] 6 and 10 , in the first buffering section 36, the first side plate region 112 and the second buffering flap portion 1214 are spaced apart along the Y-axis direction, and the second side plate region 113 and the first buffering flap portion 1213 are spaced apart along the Y-axis direction. Therefore, the first buffering section 36 provides buffering against impacts from the front side to the back side, i.e., in the +Y-axis direction, near the left end of the accommodating section 32. The first buffering section 36 also provides buffering against impacts from the back side to the front side, i.e., in the -Y-axis direction, near the left end of the accommodating section 32.

[0091] Therefore, the first buffer portion 36 fits the first end 221 of the toner cartridge 12 and buffers impacts from the up-down, left-right, and front-rear directions.

[0092] 5, 9, and 11, the second buffer section 38 has the bottom 111 and the second bottom contact section 124 overlapped along the Z axis near the lower end of the storage section 32. Therefore, near the lower end of the storage section 32, the underside of the second end 222 of the toner cartridge 12 is supported by two cardboard sheets. Therefore, near the lower end of the storage section 32, the circulator 10 exhibits buffering properties against impacts from below along the Z axis of the third side plate section 43 of the circulator 10.

[0093] 5, 6, 9, and 11, the second buffer section 38 has the second outer plate section 123, the second inner plate section 117, and the fixing plate 126 stacked along the X-axis direction. Therefore, at the fourth side plate section 44 of the storage section 32, the right side (+X-axis side) of the second end 222 of the toner cartridge 12 is supported by three cardboard sheets. Therefore, at the fourth side plate section 44 of the storage section 32, the circulator 10 exhibits buffering properties against impacts from the right side along the X-axis of the fourth side plate section 44 of the circulator 10.

[0094] The front side of the second buffer section 38 is formed by the first side plate region 112 and is therefore supported by a single cardboard sheet. The back side of the second buffer section 38 is formed by the second side plate region 113 and is therefore supported by a single cardboard sheet. For this reason, the buffering performance in the front-to-rear direction is inferior to that of the first buffer section 36.

[0095] In this way, the second buffer section 38 has lower cushioning properties than the first buffer section 36, but still has appropriate cushioning properties.

[0096] Although the second buffer portion 38 in this embodiment is not designed to fit over the second end 222 of the toner cartridge 12, it may be formed with a structure that allows for fitting, like the first buffer portion 36.

[0097] In this embodiment, when the packaging box 14 is produced from the blank 110, the blank 110 can be produced so that the heights of the protruding portion 1121 of the first side plate region 112, the first spacer portion 120, and the buffer area forming portion 125 relative to the outer surface of the bottom portion 111 are the same, as shown in Fig. 4. Therefore, when the lid portion 34 is closed on the storage portion 32 of the packaging box 14, the lid top plate 51 abuts against the protruding portion 1121 of the first side plate portion 41 (first region 112), and the bottom plate portion 40 and the lid top plate 51 can be maintained in a parallel state.

[0098] Therefore, according to this embodiment, even if the lid flap 52 is not fixed to the storage section 32 after assembly, it is possible to provide a toner cartridge packaging box 14 in which the bottom plate section 40 and the lid top plate 51 are parallel or approximately parallel, a toner cartridge circulation product 10 including a toner cartridge 12 packed in the toner cartridge packaging box 14, and a toner cartridge packaging blank 110.

[0099] In the packaging box 14 according to this embodiment, the outer surface of the bottom plate 40 that contacts the floor or the like and the outer surface of the lid top plate 51 can be made parallel (including approximately parallel) regardless of whether or not, for example, glue is applied between the first side plate 41 and the lid flap 52. Therefore, when multiple circulating media 10 are stacked, they can be stacked straight on top. Therefore, the circulating media 10 according to this embodiment can be prevented from collapsing during transportation.

[0100] Therefore, the circulating medium 10 according to this embodiment is less likely to tilt obliquely when multiple circulating mediums 10 are stacked one on top of the other. This allows a larger number of circulating mediums 10 to be stacked in a single container or the like. Therefore, by using the circulating medium 10 according to this embodiment, it is possible to reduce the transportation costs when transporting the circulating medium 10. Furthermore, it is possible to reduce the impact on the environment when transporting the circulating medium 10 according to this embodiment.

[0101] Furthermore, the packaging box 14 according to this embodiment is made from a blank 110 in which the box-shaped storage section 32, the lid section 34, the first buffer section 36, and the second buffer section 38 are integrally formed. Therefore, the blank 110 can be transported as a single piece rather than as multiple pieces. Therefore, the blank 110 according to this embodiment can be made smaller than a blank formed from multiple pieces. Therefore, by using the blank 110 according to this embodiment, the transportation cost of the blank 110 can be reduced. Furthermore, the impact on the environment when transporting the blank 110 according to this embodiment can be reduced.

[0102] In the present embodiment, an example has been described in which the first buffer section 36 and the second buffer section 38 are provided integrally with the storage section 32. The first buffer section 36 and the second buffer section 38 do not have to be provided integrally with the storage section 32.

[0103] The shapes of the first buffer section 36 and the second buffer section 38 of the packaging box 14 are merely examples. The shapes of the first buffer section 36 and the second buffer section 38 can be set in various ways. In addition, for example, it is also preferable that the storage section 32 and the first buffer section 36 of the packaging box 14 are formed as separate bodies.

[0104] In the present embodiment, an example has been described in which both the first buffer section 36 and the second buffer section 38 are provided in the storage section 32. For example, the storage section 32 does not necessarily need to be provided with the second buffer section 38. In other words, it is sufficient that a buffer section is provided on at least one side of the end of the storage section 32 in the longitudinal direction.

[0105] In the present embodiment, the protrusion 1121 of the first side plate region 112, the first spacer portion 120, and the buffer area forming portion 125 are described as being positioned to be flush with each other. The first spacer portion 120 may be positioned below the protrusion 1121 of the first side plate region 112 when the packaging box 14 is placed as shown in Fig. 4.
