DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of a packaging set according to the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference symbols and will not be described repeatedly. In this embodiment, the drawings show an X-axis, a Y-axis, and a Z-axis that are perpendicular to each other. The Z-axis is parallel to the vertical direction, and the X-axis and the Y-axis are parallel to the horizontal direction.

[0011] A packing set 300 for packing an electric device AA will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a perspective view showing the packing set 300. Fig. 2 is a cross-sectional view showing the packing set 300 cut along a cutting line II in Fig. 1. As shown in Figs. 1 and 2, the packing set 300 includes a packing box 200 and an electric device AA. The electric device AA is an example of an "object". The packing box 200 includes a housing member 100 and a cushioning member 210.

[0012] 1 to 3, the cushioning member 210 will be described. Fig. 3 is a perspective view showing the cushioning member 210. As shown in Figs. 1 to 3, the cushioning member 210 is housed in the housing member 100.

[0013] The buffer member 210 is disposed between the electric device AA and the housing member 100. The material of the buffer member 210 is a thin plate-shaped synthetic resin or a fiber molded product such as a pulp mold, and is molded, for example, by a press.

[0014] The cushioning member 210 includes a fixing portion 211 and a flange portion 212. The fixing portion 211 fixes the electric device AA. Specifically, the fixing portion 211 has a recess 211a. The recess 211a is recessed downward. The shape of the recess 211a corresponds to the shape of the electric device AA. Specifically, the recess 211a is disposed in the center of the fixing portion 211. A user attaches the electric device AA to the recess 211a or detaches the electric device AA from the recess 211a.

[0015] The flange portion 212 protrudes outward from the outer lower end of the fixing portion 211. Specifically, the flange portion 212 protrudes outward from the outer lower end of the entire circumference of the flange portion 212. More specifically, the shape of the flange portion 212 is a quadrangular ring. The outer periphery of the flange portion 212 has approximately the same dimensions as the inner wall of the accommodating member 100. This allows the flange portion 212 to be in contact with the inner wall of the accommodating member 100, preventing the buffer member 210 from moving within the accommodating member 100.

[0016] Next, the storage member 100 will be described. The storage member 100 stores the electric device AA. The storage member 100 is a box-shaped member. Specifically, the storage member 100 is made of cardboard or thick paper.

[0017] The housing member 100 includes a cylindrical portion 10. The cylindrical portion 10 extends along a first direction D1. The first direction D1 is an example of a "horizontal direction." The first direction D1 extends along the positive direction of the X-axis. The cylindrical portion 10 includes a first opening 20 and a second opening 30.

[0018] The first opening 20 is disposed at one end of the tubular portion 10. The first opening 20 communicates the inside of the tubular portion 10 with the outside of the tubular portion 10.

[0019] The second opening 30 is disposed at the other end of the tubular portion 10. The second opening 30 communicates the inside of the tubular portion 10 with the outside of the tubular portion 10.

[0020] Continuing with reference to Figures 1 to 4, the storage member 100 will be described in detail. Figure 4 is a development view of the storage member 100. As shown in Figures 1 to 4, the storage member 100 further includes a cover member 60.

[0021] The cylindrical portion 10 further includes a top wall 11, a bottom wall 12, a first side wall 13, and a second side wall 14. The top wall 11 faces the bottom wall 12 in a vertical direction D3. The vertical direction D3 extends along the positive direction of the Z axis. For example, information about the electrical device AA is printed on the top wall 11.

[0022] The first side wall 13 is disposed between the top wall 11 and the bottom wall 12. The second side wall 14 is disposed between the top wall 11 and the bottom wall 12. The second side wall 14 faces the first side wall 13.

[0023] The cover member 60 further includes an upper member 40 and a lower member 50 .

[0024] The upper member 40 is a plate-shaped member. Specifically, the upper member 40 has an upper member base end portion 41, an upper member main body portion 42, and an upper member tip portion 43. The upper member main body portion 42 is disposed between the upper member base end portion 41 and the upper member tip portion 43.

[0025] Specifically, the upper member main body 42 has a predetermined distance LA between the upper member base end 41 and the upper member tip end 43. The predetermined distance LA is half the distance from the upper end to the lower end of the first opening 20. In other words, the predetermined distance LA is half the distance from the top wall 11 to the bottom wall 12.

[0026] The upper member tip portion 43 has two protrusions. Specifically, the upper member tip portion 43 has a first protrusion 43a and a second protrusion 43b. A predetermined distance is provided between the first protrusion 43a and the second protrusion 43b in the Y direction.

[0027] The upper member base end 41 is connected to an upper end of the first opening 20. Specifically, the upper member base end 41 is connected to one end of the top wall 11. The upper member 40 rotates about the upper member base end 41 as a rotation axis. Specifically, the upper member 40 can be switched between an open state and a closed state.

[0028] Moreover, lower member 50 is a plate-like member. Specifically, lower member 50 has lower member base end portion 51, lower member main body portion 52, and lower member tip portion 53. Lower member main body portion 52 is disposed between lower member base end portion 51 and lower member tip portion 53.

[0029] The lower member main body portion 52 has a predetermined distance LA between the lower member base end portion 51 and the lower member tip end portion 53. The predetermined distance LA is half the distance from the upper end to the lower end of the first opening 20. In other words, the predetermined distance LA is half the distance from the top wall 11 to the bottom wall 12.

[0030] The lower member tip portion 53 has three convex portions. Specifically, the lower member tip portion 53 has a third convex portion 53a, a fourth convex portion 53b, and a fifth convex portion 53c. In the Y direction, a predetermined distance is provided between the third convex portion 53a and the fourth convex portion 53b. In the Y direction, a predetermined distance is provided between the fourth convex portion 53b and the fifth convex portion 53c.

[0031] The lower member base end 51 is connected to a lower end of the first opening 20. Specifically, the upper member base end 41 is connected to one end of the bottom wall 12. The lower member 50 rotates about the lower member base end 51 as a rotation axis. Specifically, the lower member 50 can be switched between an open state and a closed state.

[0032] The upper member tip portion 43 and the lower member tip portion 53 are engaged. Specifically, the upper member tip portion 43 and the lower member tip portion 53 are engaged at the center of the first opening 20. In other words, the first opening 20 is closed by the cover member 60. In detail, the first convex portion 43a is inserted between the fourth convex portion 53b and the fifth convex portion 53c, and the second convex portion 43b is inserted between the third convex portion 53a and the fourth convex portion 53b. In other words, the upper member tip portion 43 and the lower member tip portion 53 are fitted together so as to overlap in the X direction to cover the first opening 20, and do not have a piece protruding toward the inside (X direction) of the cylindrical portion 10.

[0033] As described above, according to the packaging box 200, the upper member tip portion 43 and the lower member tip portion 53 are not located at the peripheral end portion of the first opening 20, so that interference between the upper member tip portion 43, the lower member tip portion 53, and the flange portion 212 can be suppressed. As a result, when the cushioning member 210 is inserted from the second opening 30 after the first opening 20 is closed with the lid member 60, the upper member tip portion 43 and the lower member tip portion 53 are not pushed out by the flange portion 212, and the state in which the first opening 20 is closed with the lid member 60 can be maintained. Therefore, the electrical device AA can be easily accommodated in the packaging box 200.

[0034] Moreover, the upper member tip portion 43 and the lower member tip portion 53 are engaged at the center of the first opening 20. In other words, the upper member tip portion 43 and the lower member tip portion 53 are not disposed at the lower end of the first opening 20. As a result, interference between the upper member tip portion 43, the lower member tip portion 53, and the flange portion 212 can be further suppressed.

[0035] Further, lower member main body portion 52 has a predetermined distance LA between lower member base end portion 51 and lower member tip portion 53. In other words, upper member tip portion 43 and lower member tip portion 53 are not disposed at the lower end of first opening 20. As a result, interference between upper member tip portion 43, lower member tip portion 53, and flange portion 212 can be further suppressed.

[0036] More specifically, the storage member 100 further includes a first side member 70 and a second side member 80 .

[0037] The first side member 70 is a plate-shaped member. Specifically, the first side member 70 has a first side member base end portion 71 and a first side member tip portion 73. The upper side member base end portion 41 is connected to one end portion of the first side wall 13.

[0038] The first side member 70 rotates about the first side member base end portion 71 as a rotation axis. Specifically, the first side member 70 can be switched between an open state and a closed state. In more detail, the first side member 70 is disposed inside the tubular portion 10 with respect to the upper side member 40 and the lower side member 50.

[0039] A recess 73a is formed at the lower end of the first side member tip portion 73. The recess 73a corresponds to the flange portion 212. As a result, interference between the first side member tip portion 73 and the flange portion 212 can be suppressed. Therefore, the first side member tip portion 73 is not pushed out by the flange portion 212.

[0040] The second side member 80 is a plate-shaped member. Specifically, the second side member 80 has a second side member base end portion 81 and a second side member tip portion 83. The second side member base end portion 81 is connected to one end portion of the second side wall 14.

[0041] The second side member 80 rotates about the second side member base end portion 81 as a rotation axis. Specifically, the second side member 80 can be switched between an open state and a closed state. In particular, the second side member 80 is disposed inside the tubular portion 10 with respect to the upper side member 40 and the lower side member 50.

[0042] A recess 83a is formed at the lower end of the second side member tip portion 83. The recess 83a corresponds to the flange portion 212. As a result, interference between the second side member tip portion 83 and the flange portion 212 can be suppressed. Therefore, the second side member tip portion 83 is not pushed out by the flange portion 212.

[0043] As described above, according to the packaging box 200, the flange portion 212 is disposed in the recess 73a and the recess 83a. As a result, interference between the first side member 70, the second side member 80, and the flange portion 212 can be suppressed. Therefore, when the cushioning member 210 is inserted from the second opening 30 after the first opening 20 is closed by the lid member 60, the first side member tip portion 73 and the second side member tip portion 83 are not pushed out by the flange portion 212, and the state in which the first opening 20 is closed by the lid member 60 can be maintained.

[0044] More specifically, the storage member 100 further includes a second opening side cover member 160. The second opening side cover member 160 further includes a second opening side upper member 140 and a second opening side lower member 150.

[0045] The second opening side upper member 140 is a plate-shaped member. Specifically, the second opening side upper member 140 has an upper member base end portion 141, an upper member main body portion 142, and an upper member tip portion 143. The upper member main body portion 142 is disposed between the upper member base end portion 141 and the upper member tip portion 143.

[0046] Upper member body portion 142 has a set distance LB between upper member base end portion 141 and upper member tip end portion 143. Set distance LB is the same length as the distance from top wall 11 to bottom wall 12.

[0047] The upper member base end 141 is connected to the upper end of the second opening 30. In particular, the upper member base end 141 is connected to the other end of the top wall 11. The upper member main body 142 rotates around the upper member base end 141 as a rotation axis. In addition, the upper member tip portion 143 rotates around the upper member main body 142 as a rotation axis. Specifically, the second opening side upper member 140 is switched to either an open state or a closed state. When the second opening side upper member 140 is in the closed state, the upper member tip portion 143 is inserted into the inside of the tubular portion 10. And the upper member tip portion 143 is disposed below the flange portion 212.

[0048] Moreover, the second opening side lower member 150 is a plate-shaped member. Specifically, the second opening side lower member 150 has a lower member base end portion 151 and a lower member main body portion 152. The lower member main body portion 152 has a set distance LB between the lower member base end portion 151 and the tip end portion. The set distance LB is the same length as the distance from the top wall 11 to the bottom wall 12.

[0049] The lower member base end 151 is connected to the lower end of the second opening 30. Specifically, the lower member base end 151 is connected to the other end of the bottom wall 12. The lower member main body 152 rotates about the lower member base end 151 as the rotation axis. Specifically, the second opening side lower member 150 can be switched between an open state and a closed state.

[0050] An opening 152a is formed in the lower member main body 152. The opening 152a corresponds to the upper member tip 143. As a result, when the second opening side lower member 150 is in a closed state and the second opening side upper member 140 is in a closed state, the upper member tip 143 is inserted into the opening 152a.

[0051] The second opening side upper member 140 and the second opening side lower member 150 are connected. In other words, the second opening 30 is closed by the second opening side cover member 160. Specifically, the upper member tip portion 143 is inserted into the opening 152a.

[0052] More specifically, the storage member 100 further includes a second opening first side member 170 and a second opening second side member 180 .

[0053] The second opening side first side member 170 is a plate-like member. The second opening side first side member 170 is connected to the other end of the first side wall 13. The second opening side first side member 170 rotates. Specifically, the second opening side first side member 170 is switched to either an open state or a closed state. In particular, the second opening side first side member 170 is disposed inside the cylindrical portion 10 with respect to the second opening side upper member 140 and the second opening side lower member 150.

[0054] A recess 170a is formed at the lower end of the second opening side first side member 170. The recess 170a corresponds to the flange portion 212. As a result, interference between the second opening side first side member 170 and the flange portion 212 can be suppressed. This makes it less likely that the second opening side first side member 170 will interfere with the flange portion 212 and not switch to the closed state.

[0055] Moreover, the second opening side second side member 180 is a plate-like member. The second opening side second side member 180 is connected to the other end of the second side wall 14. The second opening side second side member 180 rotates. Specifically, the second opening side second side member 180 is switched to either an open state or a closed state. In particular, the second opening side second side member 180 is disposed inside the tubular portion 10 with respect to the second opening side upper member 140 and the second opening side lower member 150.

[0056] A recess 180a is formed at the lower end of the second opening side second side member 180. The recess 180a corresponds to the flange portion 212. As a result, interference between the second opening side second side member 180 and the flange portion 212 can be suppressed. This makes it less likely that the second opening side second side member 180 will interfere with the flange portion 212 and not switch to the closed state.

[0057] As described above, according to the packaging box 200, the flange portion 212 is disposed in the recesses 170a and 180a. As a result, interference between the second opening side first side member 170, the second opening side second side member 180, and the flange portion 212 can be suppressed. Therefore, after the cushioning member 210 is inserted from the second opening 30, the second opening 30 can be easily covered with the second opening side cover member 160.

[0058] Next, a packing method for packing the electric device AA in the packing box 200 will be described with reference to Fig. 5. Fig. 5 is a cross-sectional view showing a packing set according to the present embodiment. As shown in Fig. 5, the packing method is carried out by, for example, a packing device and an operator.

[0059] First, the packing device rotates the first side member 70 around the first side member base end portion 71 as a rotation axis to close the first side member 70. The packing device also rotates the second side member 80 around the second side member base end portion 81 as a rotation axis to close the second side member 80.

[0060] Next, the packing device rotates the upper member 40 around the upper member base end 41 as a rotation axis to close the upper member 40. The packing device also rotates the lower member 50 around the lower member base end 51 as a rotation axis to close the lower member 50. Specifically, the first convex portion 43a is inserted between the fourth convex portion 53b and the fifth convex portion 53c, and the second convex portion 43b is inserted between the third convex portion 53a and the fourth convex portion 53b. The first opening 20 is closed by the lid member 60.

[0061] Meanwhile, the packaging device inserts the electric device AA into the recess 211a of the buffer member 210. Next, the buffer member 210 containing the electric device AA is inserted from the second opening 30. At this time, interference between the upper member tip 43, the lower member tip 53, and the flange portion 212 can be suppressed. In addition, interference between the first side member 70, the second side member 80, and the flange portion 212 can be suppressed. As a result, the components of the lid member 60 are not pushed out by the flange portion 212, and the first opening 20 can be maintained in a state where it is closed by the lid member 60. In addition, since the flange portion 212 is unlikely to hit the components of the lid member 60, the buffer member 210 can be smoothly inserted into the containing member 100, improving workability.

[0062] Next, the worker rotates the second opening side first side member 170 to close the second opening side first side member 170. In addition, the worker rotates the second opening side second side member 180 to close the second opening side second side member 180.

[0063] Next, while visually checking the position of the flange portion 212, the worker rotates the second opening side lower member 150 around the lower member base end portion 151 as a rotation axis, and closes the second opening side lower member 150. Next, while visually checking the position of the flange portion 212, the worker rotates the second opening side upper member 140 around the upper member base end portion 141 as a rotation axis, and closes the second opening side upper member 140. Specifically, the upper member tip portion 143 is inserted into the opening 152a. Then, the upper member tip portion 143 is disposed below the flange portion 212. The upper member tip portion 143 is supported by being sandwiched between the flange portion 212 and the inner wall of the storage member 100, and is therefore less likely to come off, and also reinforces the strength of the packaging box 200.

[0064] The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above embodiments, and can be implemented in various forms without departing from the scope of the present invention. The drawings are mainly schematic illustrations of each component for ease of understanding, and the thickness, length, number, etc. of each component shown in the drawings are different from the actual ones due to the convenience of drawing. In addition, the materials, shapes, dimensions, etc. of each component shown in the above embodiments are merely examples, and are not particularly limited, and various modifications are possible within a scope that does not substantially deviate from the effects of the present invention.

[0065] (1) In this embodiment, upper member tip portion 43 has two convex portions, and lower member tip portion 53 has three convex portions. However, the present invention is not limited to this. Upper member tip portion 43 may have three convex portions, and lower member tip portion 53 may have two convex portions. Note that it is sufficient that upper member tip portion 43 has at least one convex portion, and lower member tip portion 53 has at least one convex portion.

[0066] (2) In this embodiment, the lid member 60, in which the upper member tip portion 43 and the lower member tip portion 53 are engaged with each other at the center of the first opening 20, is disposed in the first opening 20. However, the present invention is not limited to this. The lid member 60 may be disposed in the second opening 30. [Industrial Applicability]
