[0010] Hereinafter, one embodiment of a packaging box according to the present invention will be described with reference to Fig. 1 to Fig. 12. Note that, in the following, a case where the packaging box according to the present invention is used to store equipment such as musical instruments will be described as an example, but the embodiment to which the present invention can be applied is not limited to this.

[0011] FIG. 1 is an external perspective view showing the assembled state of a packaging box in this embodiment (a packaged state in which a packaged object as an "article" can be accommodated therein, a "first usage mode" as a packaging box). As shown in FIG. 1, a packaging box 1 in this embodiment has a substantially rectangular parallelepiped shape when assembled as a box, and includes a box body 2 (lower box, main box) and a lid body 3 (lid box). The box body 2 and the lid 3 constituting the packaging box 1 are formed by assembling strong plate materials having a certain thickness, such as paperboard or corrugated cardboard. The packaging box 1 of this embodiment can be transformed from a packaging state (assembled state as a box, "first usage mode") in which an object to be packaged can be stored inside as a box to a stand state ("second usage mode") in which it can be used as a desk (placement stand, see Figs. 10 to 12) by rearranging the box body 2 and the lid 3. The transformation of the packaging box 1 from the assembled state as a box ("first usage mode") to the stand state as a desk ("second usage mode") will be described later.

[0012] FIG. 2 is a perspective view showing a state in which the lid is removed from the main body of the packaging box to open the box. 2, the box body 2 is substantially rectangular parallelepiped in shape and has an opening 20 at the top. In a "first usage mode" in which the packaging box 1 is used as a box, an object to be packaged (an article) is placed inside through the opening 20. The lid body 3 has an approximately rectangular parallelepiped shape corresponding to the box body 2, and is large enough to function as a lid covering the opening 20 of the box body 2 when the packaging box 1 is in the packaged state shown in Figure 1 (assembled state as a box, "first usage mode").

[0013] Fig. 3 is a diagram showing the box body in an unfolded state, and Fig. 4 is a diagram showing the lid in an unfolded state. In Figs. 1 to 4, the longitudinal direction (long side direction) of the packaging box 1 is the X direction, and the short side direction of the packaging box 1 is the Y direction.

[0014] As shown in FIG. 3, the box body 2 includes a bottom plate 21 that constitutes the bottom surface of the box body 2 when assembled into a box. A pair of first side panels 22 (a pair of first side panels 22 constituting a first side and a second side opposite the first side) are connected to each of a pair of long sides of the bottom panel 21 via "fold lines 211" that are fold lines along the longitudinal direction X. The folded side panel 23 is connected to the first side panel 22 via a "fold line 231" on the side opposite to the side connected to the bottom panel 21 (i.e., the side connected to or continuously provided; the same applies hereinafter in this embodiment). The folded side panel 23 is folded into the inside of the box body 2 along the "fold line 231" to overlap the first side panel 22. The first side panel 22 and the folded-back side panel 23 overlapping therewith constitute a longitudinal side wall (the "first side wall") of the box body 2 that rises almost vertically from the bottom panel 21, which is the bottom surface, when assembled into a box.

[0015] The first side wall is formed by the first side panel 22 and the folded-back side panel 23 overlapping therewith, so that it is possible to ensure greater rigidity than in the case where the first side wall is constituted by only the first side panel 22. In addition, by folding the folded side panel 23 inside the box body 2 and overlapping it with the first side panel 22, the end face of the plate material from which the packaging box 1 is made is not exposed in the assembled state, which makes it possible to prevent injuries to fingers caused by the end face of the plate material.

[0016] One of the folded side panels 23 respectively connected to a pair of first side panels 22 (in the example shown in Figure 3, the lower folded side panel 23 in the Y direction) has a pair of step-forming pieces 24 connected via "fold lines 241" on the edge opposite to the side connected to the first side panel 22. The step-forming piece 24 has a rectangular main piece 24a extending from the folded side panel 23 along the Y direction, and a folded tongue piece 24b protruding in the X direction from the base end and free end of the main piece 24a via a "fold line 242", and the entire piece is formed approximately in a U-shape.

[0017] The pair of step-forming pieces 24 are provided at both ends of the folded side panel 23 in the X direction, respectively, and are arranged so that the folded tongue pieces 24b face each other. The length y2 of piece 24a in the Y direction is approximately equal to the length y1 of bottom plate 21 in the Y direction. Furthermore, the protruding length x2 of folded tongue piece 24b is approximately equal to or slightly shorter than the length (width) x1 of piece 24a in the X direction, and when folded tongue piece 24b is folded along "fold line 242," the pair of folded tongue pieces 24b overlap both ends of piece 24a, and the thickness of the overlapping parts of folded tongue pieces 24b becomes twice that of the plate material, creating a step.

[0018] With the step thus created, the step-forming piece 24 is folded inside the box body 2 along the "fold line 241." This creates a gap (gap 240 shown in FIG. 6 and elsewhere) that is the thickness of the folded tongue piece 24b between the bottom plate 21 and the main piece 24a on the bottom surface of the box body 2. The gap 240 opens toward the center of the box body 2 and serves as a first receiving portion (insertion portion) that receives a first insertion tongue piece 27c, which will be described later. The length y3 of this gap 240 in the Y direction (ie, the width between the pair of folded tongue pieces 24b) is designed to be approximately equal to or slightly larger than a width y4 of a first insertion tongue piece 27c described below.

[0019] Further, second side panels 25 (a pair of second side panels 25 constituting a third side and a fourth side opposite the third side) are connected to a pair of short sides of the bottom panel 21 via "fold lines 212". In the following embodiment, the second side panel 25 on the left side of the bottom panel 21 in FIG. 3 etc. is referred to as the "second side panel 25α" constituting the third side, and the second side panel 25 on the right side is referred to as the "second side panel 25β" constituting the fourth side. When referring to both the left and right sides, it is simply referred to as the "second side panel 25". The second side panel 25 constitutes a side wall (the "second side wall") in the short side direction of the box body 2 that rises almost vertically from the bottom plate 21, which is the bottom surface, when assembled into a box, and is formed to be approximately the same height as the "first side wall" formed by the first side panel 22 and the folded side panel 23. Further, inner flaps 26 are connected to both ends in the Y direction of second side panel 25 via "fold lines 261." In the assembled state as a box, inner flaps 26 are sandwiched between first side panel 22 and folded-back side panel 23 and are contained within the "first side wall" so as not to be exposed to the outside.

[0020] Furthermore, a flap portion 27 is connected to the side of each second side panel 25 opposite to the side connected to the bottom panel 21 via a "fold line 271." The side along the "fold line 271" is a "first side" that faces the opening 20 of the box body 2, and the flap portions 27 are each provided connected to a side wall ("second side wall") of the box body 2 with this "first side" as a base end. As described below, the pair of flap portions 27 (first "flap portion 27α" and second "flap portion 27β") in this embodiment are in a planar initial state as shown in Figure 2 etc. in the "first usage mode" as a box, and in the "second usage mode" they are folded from this state toward the inside of the opening 20, transforming into stand-state legs 270 (see Figures 8 to 12), forming a pair of first members that function as legs 270 of a desk.

[0021] The pair of flap portions 27 (the first "flap portion 27α" and the second "flap portion 27β") each have a first flap portion 27a that contacts the "fold line 271", a second flap portion 27b that is connected to the first flap portion 27a via the "fold line 272", and a first insertion tongue piece 27c that is connected to the free end side of the second flap portion 27b via the "fold line 273". When the first flap portion 27a is the "first surface," the second flap portion 27b is folded along the "fold line 272" in the "second usage mode" into a mountain shape to form a "second surface" that is inclined toward the inside of the box body 2. As mentioned above, the width y4 in the Y direction of the first insertion tongue 27c is slightly smaller than the length (width) y3 in the Y direction of the gap 240, making it possible to insert the first insertion tongue 27c into the gap 240 in the post-deformation stand state ("second usage mode") described below.

[0022] In addition, the flap portion 27 as the first member has a wide portion 27w formed to a width equal to the outer dimensions of the box main body 2, and a narrow portion 27n formed to a width equal to the inner dimensions of the box main body 2 and positioned within the box main body 2. In this embodiment, the width in the Y direction of the first flap portion 27a and the side of the second flap portion 27b that is connected to the first flap portion 27a is width y5, which is approximately the same as the inner dimension of the box body 2. In contrast, the side of the second flap portion 27b that is in contact with the first insertion tongue piece 27c has a width y6 in the Y direction that is narrower than width y5. As shown in Fig. 3, the part of the flap portion 27 that has a width y5 in the Y direction is referred to as a wide width portion 27w, and the part that has a width y6 is referred to as a narrow width portion 27n.

[0023] A step is generated at the portion where the narrow portion 27n changes to the wide portion 27w, forming a step portion 27s (see FIG. 6, etc.). That is, since the flap portion 27 is placed over the opening 20 of the box main body 2, it is formed to be the same as or slightly larger than the width in the Y direction of the opening 20 (which is approximately the same as the outer dimensions of the box main body 2, and the width y1 in the Y direction of the bottom plate 21); however, the narrow portion 27n is formed to a width y6 which allows it to be inserted into the opening of the box main body 2, and as described below, when the flap portion 27 is folded into a standing state, only the narrow portion 27n is inserted into the box main body 2, and the step portion 27s is engaged with the end face of the opening of the box main body 2 (in this embodiment, the edge of the "first side wall") (see Figures 7 to 9).

[0024] Furthermore, a folded portion 27d is provided at the outer edge of the first flap portion 27a and the second flap portion 27b constituting the flap portion 27. The folded portion 27d is a margin-like edging. The folded portion 27d is folded back onto the surface of the first flap portion 27a and the second flap portion 27b that will be the inside of the packaging box 1 at the shipping stage of the packaging box 1, and is fixed by gluing or the like. By fixing the folded-back portion 27d in a folded-back state to the outer edge portions of the first flap portion 27a and the second flap portion 27b in this manner, the thickness of the outer edge portions of the first flap portion 27a and the second flap portion 27b is doubled, thereby increasing rigidity. Furthermore, by fixing the folded portion 27d in the folded state, the end faces of the plate material from which the packaging box 1 is made are not exposed in the assembled state, which prevents injuries to fingers caused by the end faces of the plate material.

[0025] Next, as shown in FIG. 4, the lid 3 has a top panel 31 that constitutes the top surface of the packaging box 1 in the assembled state as a box (the "first mode of use"). A first side panel 32 is connected to a pair of long sides of the top panel 31 via "fold lines 311" which are fold lines along the longitudinal direction (long side direction) X. A folded side panel 33 is connected to the opposite side of the first side panel 32 from the side connected to the top panel 31 via "fold line 331". The folded side panel 33 overlaps with the first side panel 32 by being folded inside the lid 3 along the "fold line 331". The first side panel 32 and the folded side panel 33 overlapping therewith form a longitudinal side wall ("first side wall") of the lid 3 which rises almost vertically from the top panel 31, which is the top surface, when assembled as a lid for a box.

[0026] The "first side wall" is formed by the first side panel 32 and the folded-back side panel 33 overlapping therewith, so that it is possible to ensure greater rigidity than in the case where it is constituted by only the first side panel 32. In addition, by folding the folded side panel 33 inside the lid body 3 and overlapping it with the first side panel 32, the end face of the plate material from which the packaging box 1 is made is not exposed in the assembled state, which makes it possible to prevent injuries to fingers caused by the end face of the plate material.

[0027] A step forming portion 34 is connected via a "fold line 341" to the edge opposite to the connected side to the first side panel 32 of one of the folded side panels 33 (in the example shown in Figure 4, the lower folded side panel 33 in the Y direction) respectively connected to a pair of first side panels 32. The step forming portion 34 has a rectangular main piece 34a extending in the Y direction from the folded side panel 33, and a folded tongue piece 34b protruding in the Y direction from the free end of the main piece 34a via a "fold line 342".

[0028] The folded tongue pieces 34b are provided at both ends of the main piece 34a in the X direction. The protruding length x12 of the folded tongue piece 34b is shorter than the length (width) x11 in the X-direction of the main piece 34a, and when the folded tongue piece 34b is folded along the "fold line 342", the pair of folded tongue pieces 34b overlap both ends of the main piece 34a and the thickness of the overlapping part of the folded tongue pieces 34b becomes twice that of the plate material, creating a step.

[0029] With the step thus created, the step forming portion 34 is folded inside the lid 3 along the "fold line 341." This creates a gap (gap 340 shown in FIG. 6 and other figures) that is the thickness of the folded tongue piece 34b between the top panel 31 and the main piece 34a on the top surface of the lid 3. The gap 340 opens toward the center of the lid 3 and serves as a second receiving portion (insertion portion) that receives the second insertion tongue piece 35b described below. The length y14 of this gap 340 in the X direction (ie, the width between the pair of folded tongue pieces 34b) is designed to be approximately equal to or slightly larger than a width x15 of a second insertion tongue piece 35b, which will be described later.

[0030] In addition, the other of the folded side panels 33 respectively connected to the first side panel 32 (in the example shown in Figure 4, the upper folded side panel 33 in the Y direction) has a lid side flap portion 35 connected to the side opposite to the connected side to the first side panel 32 via a "fold line 351". The lid-side flap portion 35 has a flap body 35a connected to the folded side panel 33, and a second insertion tongue piece 35b connected to the free end side of the flap body 35a via a "fold line 354". As mentioned above, the width y15 in the Y direction of the second insertion tongue 35b is slightly smaller than the length (width) y14 in the Y direction of the gap 340, making it possible to insert the second insertion tongue 35b into the gap 340 in the assembled state after deformation described below.

[0031] As described below, the lid side flap portion 35 of this embodiment is a second member that functions as a regulating portion 350 (see Figures 7 to 9) that resists the force that causes the flap portion 27 to return from this folded state to the state before it was folded (i.e., the planar initial state as shown in Figures 2, 3, etc.) when the flap portion 27, which is the first member in this embodiment, becomes the leg 270 in the stand state (the "leg 270α" obtained by deforming the first "flap portion 27α" and the "leg 270β" obtained by deforming the second "flap portion 27β", see Figures 8 to 12). Specifically, the lid side flap portion 35 is provided on the inside of the lid body 3, and by folding it as described below, it forms a regulating portion 350 extending along a "second side" (side extending in the X direction) perpendicular to the "first side" (side extending in the Y direction) of the opening 20 of the box main body 2, and is interposed between a pair of legs 270 ("legs 270α" and "legs 270β") in a stand state.

[0032] The lid-side flap portion 35, which is the second member, has one end fixed to the inside of the top surface of the lid body 3 when assembled as a lid for the box. In other words, in the assembled state, the lid side flap portion 35 has its base end at the point where the "first side wall" formed by the overlapping first side panel 32 and folded side panel 33 intersects with the top panel 31, and a second insertion tongue piece 35b is provided on the free end side. As described above, a step forming portion 34 is provided on the side opposite to the side to which the lid side flap portion 35 is fixed, and when the lid side flap portion 35 is folded to form the regulating portion 350, the second insertion tongue piece 35b of the lid side flap portion 35 is received in a gap 340 (second receiving portion) created on the inside of the top surface of the lid body 3 between the top panel 31 and the main piece 34a of the step forming portion 34.

[0033] Further, a pair of short sides of the top panel 31 are connected to the second side panel 36 via "fold lines 312," respectively. The second side panel 36 constitutes a side wall (the "second side wall") in the short side direction of the lid body 3 that rises almost vertically from the top panel 31, which is the top surface, when assembled as a box lid, and is formed so as to be almost the same height as the "first side wall" formed by the first side panel 32 and the folded side panel 33. Further, the inner flap 37 is connected to both ends in the Y direction of the second side panel 36 via a "fold line 371." In an assembled state, the inner flap 37 is sandwiched between the first side panel 32 and the folded-back side panel 33 and is contained within the "first side wall" so as not to be exposed to the outside.

[0034] Furthermore, a folded side panel 38 is connected to the second side panel 36 via a "fold line 381" on the side opposite to the side connected to the top panel 31. The folded side panel 38 overlaps with the second side panel 36 by being folded into the inside of the lid 3 along the "fold line 381." The second side panel 36 and the folded side panel 38 overlapping therewith form a side wall in the short side direction of the lid 3 (the "second side wall") that rises almost perpendicularly from the top panel 31, which is the top surface, when assembled as a box lid. Furthermore, by forming the "second side wall" from the second side panel 36 and the folded side panel 38 overlapping it, the rigidity of the "second side wall" is improved and, like the "first side wall," injuries to fingers caused by the edge of the plate can be prevented.

[0035] Next, with reference to the drawings, the operation of this embodiment (method of use, and method of transforming the assembled state as a box ("first usage mode") into a stand state that can be used as a desk ("second usage mode")) will be explained. In the packaging box 1 of this embodiment, when transporting or storing a packaged object Ob (a keyboard instrument is exemplified in Figure 5 etc.), the packaged object Ob is contained within the box main body 2 as shown in Figure 5, and the flap portion 27 is placed over the packaged object Ob, and then the lid body 3 is placed over that. As a result, a pair of flap portions 27, the lid side flap portion 35 and the top panel 31 of the lid body 3 are stacked on top of the packaged object Ob, preventing the top surface, etc. of the packaged object Ob from being affected by external impacts.

[0036] 6 to 10 show how the packaging box 1 is transformed from a packaging state in which it is used as a box to a stand state in which it is used as a desk ("second usage mode"). When transforming the packaging box 1 from a box to a desk, first, the flap portion 27 is opened as shown in Fig. 5, and the object Ob to be packed is removed from the packaging box 1. Fig. 6 shows the state in which the object Ob to be packed has been removed from the box body 2. In addition, in the assembled state as a box, the folded-back portion 27d is fixed to the inner surface of the flap portion 27 by gluing or the like, and the side wall portions of the box body 2 and the lid body 3 are also in the assembled state (the state shown in Fig. 6).

[0037] FIG. 7 shows one side (in FIG. 7) of the flap portion 27, which is a pair of first members of the box body 2, transformed from its initial flat state into a leg portion 270 in a stand state by folding. The leg portion 270 has a first surface that is continuous with the side wall of the box body 2 that stands up from the bottom surface of the box body 2, and a second surface that is inclined toward the inside of the box body 2 by being folded in a mountain shape from the first surface along the fold line. Specifically, the flap portion 27 is folded inwardly of the box body 2 along the "fold line 272," and the first insertion piece 27c is folded inwardly along the "fold line 273." At this time, the first insertion piece 27c is inserted and received in the gap 240, which is the first receiving portion.

[0038] As a result, a first surface is formed by the second side panel 25 that constitutes the side wall on the short side and the first flap portion 27a of the flap portion 27 connected thereto, and the second flap portion 27b is folded in a mountain shape from the first surface along the "fold line 272", so that the second flap portion 27b forms a second surface that slopes toward the inside of the box body 2. The first and second surfaces and the overlapping portion of the bottom plate 21 where the main piece 24a of the step-forming piece 24 is placed form a substantially triangular prism shape for the leg portion 270. The second side panel 25 constituting the first surface and the first flap portion 27a connected thereto intersect with the bottom plate 21 at a substantially right angle (see FIG. 8, etc.). At this time, the narrow portion 27n is inserted into the box body 2, and the step portion 27s is engaged with the edge (end face) of the opening 20 of the box body 2, thereby suppressing shifting and twisting, and making it difficult for the posture of the leg 270 in the stand state to be lost.

[0039] Figure 8 shows a pair of flap portions 27 (a first "flap portion 27α" and a second "flap portion 27β") both folded in the same manner to transform them into stand-state leg portion 270 ("leg portion 270α" and "leg portion 270β"). As shown in FIG. 8, by assembling both of the pair of flap portions 27 (27α, 27β), a pair of leg portions 270 (270α, 270β) is completed.

[0040] FIG. 8 also shows the state in which the lid body 3 has been deformed by bending the lid side flap portion 35 (the flap main body 35a of the lid side flap portion 35) to form the restricting portion 350. Specifically, the lid-side flap portion 35 (flap body 35a of the lid-side flap portion 35) is valley-folded at "fold line 352" and mountain-folded at "fold line 353" to form a mountain-shaped restricting portion 350 with the "fold line 353" as its apex. The shape of the restricting portion 350 is maintained by inserting the second insertion piece 35b into the gap 340, which is the second receiving portion.

[0041] As shown in FIG. 8, when the assembly of the legs 270 on the box body 2 and the assembly of the restricting portion 350 on the lid body 3 are completed, the box body 2 is tilted 90 degrees toward the front in the figure and the box body 2 is placed on the lid body 3. In this embodiment, the distance x5 from the bottom surface (bottom plate 21) of the box body 2 to the "fold line 272", which is the vertex position of the triangular prism-shaped leg portion 270, is less than or equal to the length y11 of the side of the lid body 3 corresponding to the first side of the box body 2 (the length corresponding to the "fold line 312"). For this reason, as shown in Fig. 9, when the box body 2 is placed on the lid body 3 with the bottom plate 21 oriented vertically, the legs 270 are arranged to fit inside the lid body 3. If the distance x5 is smaller than the length y11, the box body 2 can be placed on the lid body 3 as shown in Fig. 9, and although there are no particular limitations on the difference in size, if the distance x5 is too smaller than the length y11, the box body 2 will rattle on the lid body 3. For this reason, it is preferable that the distance x5 is set slightly smaller than the length y11 so that the lid body 3 and the box body 2 fit together as snugly as possible.

[0042] In this way, by placing the box body 2 on the lid body 3, the regulating portion 350 on the lid body 3 side is interposed between a pair of legs 270 (270α, 270β) formed when the pair of flap portions 27 (27α, 27β) are in the stand state. Both ends of the restricting portion 350 in the extending direction (X direction in FIG. 4 etc.) correspond to the inclination angle of the second surface (surface formed by the second flap portion 27b) of the leg portion 270 (270α, 270β). Specifically, the regulating portion 350 has an inclined portion 350a (see Figures 8 and 9) that corresponds to the dihedral angle between the first surface (first flap portion 27a) and the second surface (second flap portion 27b) in the pair of flap portions 27 (27α, 27β). As a result, as shown in FIG. 9, the regulating portion 350 interposed between the pair of legs 270 (270α, 270β) comes into contact with the inclined surface (second surface) formed by the second flap portion 27b at the inclined portion 350a, and in the "second usage mode", the stand state of the leg 270 can be stably maintained against the force that tends to return the flap portion 27, which is the first member, from the folded state to the state before being folded.

[0043] In this embodiment, the packaging box 1 can be transformed into a desk supported by triangular prism-shaped legs 270 as shown in Fig. 10 etc., and after transformation, the standing state of the legs 270 is maintained by the regulating part 350. Therefore, it has excellent load-bearing capacity, and even a relatively heavy object can be stably placed on it.

[0044] Then, the packaging box 1 assembled on the desk in this manner is turned over 180 degrees from the state shown in FIG. 9, and placed so that the top panel 31 of the lid 3 becomes the upper surface (the top panel of the desk) as shown in FIG. As a result, in the "second usage mode" in which it is used as a desk, one end of the flap portion 27, which is the first member, comes into contact with the lid body 3 that functions as the desk top, and the other end of the flap portion 27 comes into contact with the ground surface. Then, as shown in Fig. 11 and Fig. 12, the top panel 31 can be used as a placement surface (table surface), and the packaged object Ob, etc., originally contained in the packaging box 1 can be placed on the top panel 31 and used as a desk (placement stand).

[0045] As described above, the packaging box 1 of this embodiment comprises a box body 2 including an opening 20 for placing an object to be packaged Ob inside in the "first mode of use" as a box, and a flap portion 27 as a first member that can be folded toward the inside of the opening 20 to function as desk legs 270 in the "second mode of use" as a desk, and a lid body 3 that covers the opening 20 in the "first mode of use" and that does not cover the opening 20 in the "second mode of use", but rather contacts one end of the folded flap portion 27 (first member) and functions as a desk top. This allows the packaged object Ob contained in the package box 1 and delivered to be placed on the desk (mounting stand) transformed from the package box 1 and used immediately, allowing the user who receives the delivery to easily enjoy it without having to prepare a separate table or stand. Moreover, the packaging box 1 can be reused as a desk (a table), making effective use of the packaging box 1 and reducing waste.

[0046] In this embodiment, the portions (e.g., folded-back portion 27d, etc.) other than the portions necessary for changing the packaging box 1 into a desk (e.g., the folded portion of the flap portion 27, the first insertion tongue 27c, the gap 240 for receiving the first insertion tongue 27c, the folded portion of the lid-side flap portion 35, the second insertion tongue 35b, the gap 340 for receiving the second insertion tongue 35b, etc.) are fixed by gluing or the like at the time of shipping as the packaging box 1. Therefore, a user who receives the packaging box 1 can easily and safely change the packaging box 1 into a desk by simply folding and deforming it appropriately along the fold lines without using scissors, a cutter, glue, or tape. In this way, the transformation from a box to a desk is performed by folding and the like, and does not require gluing, so even after it has been transformed into a desk, it can be easily returned to the assembled state as a box. Therefore, when the object Ob to be packed is not in use, the packing box 1 can be returned to its original box state and used to store equipment such as musical instruments.

[0047] In addition, the lid body 3 of this embodiment includes a lid side flap portion 35 as a second member that functions as a regulating portion 350 that resists the force that causes the flap portion 27 as the first member to return from the folded state to the state before being folded in the "second usage mode." As a result, by deforming and combining the box body 2 and the lid body 3, a desk (placing table) that can stably maintain its shape can be formed. Therefore, the packaging box 1 can be reused as a desk (mounting table).

[0048] In the "second usage mode", the flap portion 27 which is the first member of this embodiment has one end in contact with the lid 3 which functions as the desk top, and the other end in contact with the ground surface. This allows the shape to be stably maintained in the "second usage mode" in which it is used as a desk (mounting stand).

[0049] The box main body 2 includes a first side, a second side opposite the first side, a third side, and a fourth side opposite the third side, and the flap portion 27, which is a first member, is connected to at least either the third side or the fourth side. By providing the flap portion 27, which functions as the leg portion 270 of the desk in the "second usage mode" as a desk, on either of the opposing faces as a box, a stable leg portion 270 can be formed.

[0050] In addition, the flap portion 27, which is the first member in this embodiment, includes a first flap portion 27 (27α) connected to the "second side panel 25 (25α)" that constitutes the third side of the box main body 2, and a second flap portion 27 (27β) connected to the "second side panel 25 (25β)" that constitutes the fourth side of the box main body 2, and the lid side flap portion 35, which is the second member that functions as the regulating portion 350 in the "second usage mode", is provided on the inside of the lid body 3, and is positioned between the first flap portion 27 (27α) and the second flap portion 27 (27β) in the "second usage mode". The flap portions 27 (27α, 27β) which function as legs 270 of the desk in the "second usage mode" as a desk are respectively connected to the "second side panel 25 (25α)" which constitutes the opposing third side surface and the "second side panel 25 (25β)" which constitutes the fourth side surface when assembled as a box, thereby forming stable legs 270.

[0051] In addition, the flap portion 27, which is the first member in this embodiment, has a first surface (first flap portion 27a) and a second surface (second flap portion 27b) that is inclined toward the inside of the box body 2 by being folded into a mountain shape along the "fold line 272" in the "second usage mode", and the regulating portion 350, which resists the force that causes the flap portion 27, which is the first member, to return from the folded state to the state before being folded in the "second usage mode", has an inclined portion 350a that corresponds to the dihedral angle between the first surface (first flap portion 27a) and the second surface (second flap portion 27b). This allows the restricting portion 350 to reliably maintain the shape of the leg portion 270.

[0052] In this embodiment, in the "second usage mode", the length of the leg portion 270 in the front-rear direction is shorter than the length of the cover body 3 in the front-rear direction. As a result, after the flap portions 27 of the box body 2 are deformed into the leg portions 270, the box body 2 can be fitted into the lid body 3.

[0053] In addition, in this embodiment, a first insertion tongue 27c is provided on the free end side of the flap portion 27, which is the first member, and a gap 240 is provided in the box main body 2 as a first receiving portion for receiving this first insertion tongue 27c. Therefore, the deformed state can be maintained by inserting the first insertion tongue piece 27c into the gap 240, and the legs 270 can be temporarily fixed until they are firmly restricted by the restricting portion 350 of the lid body 3. This makes it possible to prevent the partially assembled state from collapsing even if the box body 2 is moved slightly before being set on the lid body 3, and even a user who is not good at assembly work can easily transform the packaging box 1 into a desk.

[0054] In addition, the lid side flap portion 35, which is the second member that functions as the regulating portion 350 in the "second usage mode", has one end fixed to the inside of the top surface of the lid body 3, a second insertion tongue piece 35b is provided on the free end side of the lid side flap portion 35, and a gap 340 is provided on the inside of the top surface of the lid body 3 as a second receiving portion for receiving the second insertion tongue piece 35b. Therefore, the deformed state can be maintained by inserting the second insertion tongue piece 35b into the gap 340, and the shape of the bent restricting portion 350 can be prevented from collapsing even if the lid body 3 is moved slightly before being set on the box body 2, so that even a user who is not good at assembly work can easily transform the packaging box 1 into a desk.

[0055] In addition, the flap portion 27, which is the first member in this embodiment, has a wide portion 27w formed to a width equal to the outer dimensions of the box body 2, and a narrow portion 27n formed to a width equal to the inner dimensions of the box body 2 and disposed within the box body, and the step portion 27s, which transitions from the narrow portion 27n to the wide portion 27w, is engaged with the end surface of the opening 20 of the box body 2 in the "second usage mode". This prevents the leg portion 270 formed by the flap portion 27 from shifting or twisting, and allows the leg portion 270 to be maintained in a stable shape.

[0056] Although the embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to such an embodiment, and various modifications are possible without departing from the gist of the present invention.

[0057] For example, in the present embodiment, a case has been exemplified in which the first member constituting the leg portion 270 is the flap portion 27 provided on the box body 2, and the second member constituting the restricting portion 350 is the lid-side flap portion 35 provided on the lid body 3, but the first member and the second member are not limited to this. For example, the first member constituting the leg portion may be provided on the lid body 3, and the second member constituting the restricting portion may be provided on the box body 2. In addition, the first member constituting the leg portion and the second member constituting the regulating portion may both be provided on the box main body 2, or conversely, the first member and the second member may both be provided on the lid body 3.

[0058] Furthermore, the portion for receiving the first insertion tongue piece 27c is not limited to being at the end of the bottom plate 21. For example, a portion for receiving the first insertion tongue 27c may be provided in the center of the bottom plate 21, and the regulating portion may regulate the leg portion itself in the direction of spreading outward, while also regulating the first insertion tongue 27c in the direction of being pushed into the receiving portion from the center toward the end portion so that the first insertion tongue 27c does not come out of the receiving portion.

[0059] Furthermore, in this embodiment, an example is shown in which the box body 2 is tilted 90 degrees from the state shown in Figure 8 and placed on top of the lid body 3, but the desk can also be assembled and the legs regulated by fitting the lid body 3 into the box body 2 in the state shown in Figure 8 without performing the step of tilting the box body 2.

[0060] In addition, in this embodiment, an example is given of the case where the box body 2 is rotated 180 degrees (upside down) from the state shown in Figure 9 and the top panel 31 of the lid body 3 is used as a support surface (desk top, table surface) for placing an object, but the support surface (table surface) is not limited to being the top panel 31. For example, the box body 2 may be rotated 90 degrees from the state shown in FIG. 9, and the bottom plate 21 of the box body 2 may be used as a placement surface (desk top, table surface) on which an object is placed. Also, for example, the distance x5 from the bottom surface (bottom plate 21) of the box main body 2 to the "fold line 272" which is the apex position of the triangular prism-shaped leg portion 270, and the width y5 of the flap portion 27 may be intentionally made significantly different, so that the height of the desk can be changed depending on the orientation in which it is installed (i.e., depending on whether the top plate 31 or the bottom plate 21 is used as the supporting surface (desk top plate, table surface)).

[0061] Furthermore, the object Ob to be packed in the packing box 1 is not limited to a musical instrument as in the illustrated example. For example, an electronic device such as a laptop computer may be packed in the packing box 1, and after the electronic device is removed, the packing box 1 may be transformed into a desk (placement stand) and used as a workbench for operating the electronic device. Furthermore, the desk (placement stand) obtained by modifying the packaging box 1 may be used for purposes other than as a placement stand for the object Ob to be packed that was contained in the packaging box 1. For example, the packaging box 1 may be transformed into a desk (placement stand) and used as a personal dining table, study desk, or the like.

[0062] Of course, the present invention is not limited to the above-described embodiments and can be modified as appropriate.
