The vertical direction perpendicular to the X and Y directions is designated as the Z direction, and is indicated by arrow Z. The view from the Z direction, i.e., the vertical direction, is the plan view. In addition, the X or Y direction may sometimes be referred to as the horizontal direction.

[0032] Each drawing is only a general representation. The dimensions and proportions of the elements shown in the drawings may not necessarily match those of reality. Dimensions, proportions, and quantities of elements may also not necessarily match between multiple drawings. Hatching to represent cross-sections may be omitted if it makes the drawing difficult to read.

[0033] Furthermore, explanations of configurations not directly related to the present invention and well-known configurations may be omitted or simplified.

[0034] These also apply to the second embodiment described later.

[0035] [Packaging box] First, let me describe the packaging box of this embodiment.

[0036] As shown in Figure 11, the packaging box 10 of this embodiment is a rectangular or cubic corrugated cardboard box for packaging the product 80 (see Figure 6). Corrugated cardboard is a structure in which flat paper and corrugated paper are bonded together with adhesive. Note that in the figures of this embodiment, the cross-sections are shown as a cross-section of a board, without distinguishing between the flat paper and corrugated paper of the corrugated cardboard.

[0037] The packaging box 10 of this embodiment is composed of a bottom member 20, a lid member 30, and a packaging body 50 (see also Figures 1 and 6). The bottom member 20 is composed of a bottom plate portion 22 and a bottom side plate portion 24. Similarly, the lid member 30 is composed of a lid plate portion 32 and a lid side plate portion 34. The bottom plate portion 22 and the lid plate portion 32 are rectangular in plan view. The bottom side plate portion 24 rises up from each side of the bottom plate portion 22. The lid side plate portion 34 falls down from each side of the lid plate portion 32.

[0038] The packaging body 50 is a cylindrical member with a rectangular shape in plan view. The bottom member 20 closes the lower opening 52 of the packaging body 50. The lid member 30 closes the upper opening 54 of the packaging body 50. The inner shapes of the bottom member 20 and the lid member 30 are slightly larger than the outer shape of the packaging body 50 in plan view. Therefore, the bottom side plate portion 24 and the lid side plate portion 34 are positioned on the outside of the packaging body 50.

[0039] [Packaging] Next, the packaging of this embodiment will be described.

[0040] As mentioned above, the packaging 50 shown in Figures 1 and 6 is composed of two first packaging materials 100A and 100B and two second packaging materials 200A and 200B (see also Figure 2). Hereafter, the components constituting the first packaging material 100A will be denoted by A after their reference numeral, and the components constituting the first packaging material 100B will be denoted by B after their reference numeral. Similarly, the components constituting the second packaging material 200A will be denoted by A after their reference numeral, and the components constituting the second packaging material 200B will be denoted by B after their reference numeral.

[0041] Furthermore, as shown in Figure 2, the first packaging material 100A and the first packaging material 100B are identical components, differing only in their placement. Similarly, the second packaging material 200A and the second packaging material 200B are identical components, differing only in their placement. The same applies to the components that make up each of them. Therefore, if there is no need to distinguish between the two in the explanation, A and B may be omitted.

[0042] As shown in Figures 1, 2, and 6, the first packaging material 100 is a plate-shaped member with an L-shape in plan view, where the body side plate portion 110 and the body side plate portion 120 are connected at a corner portion 102 (see Figure 2(B)). Similarly, the second packaging material 200 is a plate-shaped member with an L-shape in plan view, where the body side plate portion 210 and the body side plate portion 220 are connected at a corner portion 202 (see Figure 2(A)). In this embodiment, the body side plate portions 110A, 110B and the body side plate portions 210A, 210B are examples of the first piece. Also, the body side plate portions 120A, 120B and the body side plate portions 220A, 220B are examples of the second piece.

[0043] As shown in Figures 1 and 6, the first packaging materials 100A and 100B are positioned such that their corners 102A and 102B are located at one diagonal corner 51A and 51B of the rectangular packaging body 50 in plan view. The second packaging materials 200A and 200B are positioned such that their corners 202A and 202B are located at the other diagonal corner 52A and 52B of the rectangular packaging body 50 in plan view. The side panels 110A and 110B of the first packaging materials 100A and 100B are positioned along the X direction. Similarly, the side panels 220A and 220B of the second packaging materials 200A and 200B are positioned along the X direction. In addition, the side panels 120A and 120B of the first packaging materials 100A and 100B are positioned along the Y direction. Similarly, the side panels 210A and 210B of the second packaging materials 200A and 200B are arranged along the Y direction.

[0044] As shown in Figures 1, 2(B), and 6, the side panels 110A, 110B, 120A, and 120B of the first packaging materials 100A and 100B have a double structure consisting of inner panels 112A, 112B, 122A, and 122B, and outer panels 114A, 114B, 124A, and 124B positioned outside the inner panels 112A, 112B, 122A, and 122B (see also Figure 3). The gaps between the inner panels 112 and 122 and the outer panels 114 and 124 are denoted as gaps S1A, S1B, S2A, and S2B. The widths of gaps S1A, S1B, S2A, and S2B are the same. Note that the inner panels 112A, 112B, 122A, and 122B are examples of inner panels. Furthermore, the outer plate portions 114A, 114B, 124A, and 124B are examples of outer pieces.

[0045] As shown in Figure 2(B), the inner plate portions 112, 122 and the outer plate portions 114, 124 of the first packaging material 100 are joined by rail portions 131A, 131B, 132A, 132B (see also Figure 3). Rail portions 131, 132 are horizontally extending strip-shaped members provided in the vertical middle of the gaps S1, S2. In this embodiment, rail portions 131A, 131B, 132A, 132B are each provided in two locations spaced apart in the vertical direction. The upper rail portions 131A, 131B, 132A, 132B are each provided in the same vertical position. Similarly, the lower rail portions 131A, 131B, 132A, 132B are each provided in the same vertical position.

[0046] The rail sections 131A and 131B of the body side plate sections 110A and 110B of the first packaging materials 100A and 100B extend along the X direction. The rail sections 132A and 132B of the body side plate sections 120A and 120B of the first packaging materials 100A and 100B extend along the Y direction.

[0047] Furthermore, as shown in Figure 4, a wide section 133B is formed at the end of the rail section 131B. In this embodiment, the wide section 133B is wide in the vertical direction because the end of the rail section 131B is convex upwards. Similarly, wide sections 133A, 134A, and 134B are formed at the ends of the other rail sections 131A, 132A, and 132B by being convex upwards (see Figure 2(B)).

[0048] In this embodiment, the inner plate portions 112, 122, outer plate portions 114, 124, and rail portions 131, 132 of the body side plate portions 110, 120 of the first packaging material 100 are made of corrugated cardboard. Therefore, the inner plate portions 112, 122 and outer plate portions 114, 124 and the rail portions 131, 132 in this embodiment are integrated by being joined together with adhesive and double-sided tape, etc.

[0049] As shown in Figure 2(A), slits 231A, 231B, 232A, and 232B are formed in the body side plate portion 210 and body side plate portion 220 of the second packaging material 200, respectively. In this embodiment, the slits 231A, 231B, 232A, and 232B are each provided in two locations spaced apart in the vertical direction. The slits 231A and 231B of the body side plate portions 210A and 210B extend along the Y direction. The slits 232A and 232B of the body side plate portions 220A and 220B extend along the X direction. The slits 231A, 231B, 232A, and 232B are each formed at the same height as the rail portions 131 and 132 (see also Figures 1, 3, and 4).

[0050] The vertical width of slits 231 and 232 is slightly larger than the vertical width of the wider sections 133 and 134 of the rail sections 131 and 132. In addition, stepped sections 233A, 233B, 234A, and 234B are formed at the opening ends of slits 231 and 232, bending downwards in a Z-shape (see also Figure 4).

[0051] The length of the stepped sections 233 and 234 in the X or Y direction is slightly greater than the length of the wide sections 133 and 134 of the rail sections 131 and 132 in the X or Y direction. Also, the width of the stepped sections 233 and 234 in the Z direction is greater than the width of the wide sections 133 and 134 of the rail sections 131 and 132 in the Z direction (see also Figure 4).

[0052] Furthermore, the portions extending from the lower ends of the stepped sections 233 and 234 of the slits 231 and 232 are designated as the opening-side slits 235A, 235B, 236A, and 236B. The vertical slit width of the opening-side slits 235A, 235B, 236A, and 236B is also slightly larger than the vertical width of the wide sections 133 and 134 of the rail sections 131 and 132 (see also Figure 4).

[0053] As shown in Figures 1 and 6, handle portions 90 are provided at the vertical midpoints of the corners 102A and 102B of the first packaging materials 100A and 100B (see also Figure 5). Similarly, handle portions 90 are provided at the vertical midpoints of the corners 202A and 202B of the second packaging materials 200A and 200B (see also Figure 5). The handle portions 90 of the corners 102A, 102B, 202A, and 202B are provided at the same height.

[0054] The handle portion 90 in this embodiment is a plate-like member created by folding a single piece of corrugated cardboard into an L-shape in plan view. In this embodiment, the handle portion 90 made of corrugated cardboard is joined to the corners 102 and 202 with adhesive and double-sided tape or the like.

[0055] As mentioned above, the side panels 110 and 120 of the first packaging material 100 shown in Figures 1 and 6 have a double structure consisting of inner panels 112 and 122 and outer panels 114 and 124 (see also Figure 2(B), etc.). The side panels 210 and 220 of the second packaging material 200 are inserted into the gaps S1 and S2 between the inner panels 112 and 122 and the outer panels 114 and 124.

[0056] Specifically, the shell side plate portion 210A of the second packaging material 200A is inserted into the gap S2B of the adjacent first packaging material 100B. The shell side plate portion 220A is inserted into the gap S1A of the adjacent first packaging material 100A. Similarly, the shell side plate portion 210B of the second packaging material 200B is inserted into the gap S2A of the adjacent first packaging material 100B. The shell side plate portion 220B is inserted into the gap S1B of the adjacent first packaging material 100B.

[0057] Furthermore, the rail sections 131A, 131B, 132A, and 132B of the first packaging material 100 (see Figure 2) are inserted into the slits 231A, 231B, 232A, and 232B of the second packaging material 200 (see Figure 2) (see also Figures 3, 4, and 6).

[0058] Therefore, as shown in Figure 6, the packaging body 50 is configured such that the body side plate portions 110 and 120 of adjacent first packaging material 100 and the body side plate portions 210 and 220 of second packaging material 200 are slidably connected in the direction in which the corner portions 102 and 202 move toward and toward each other.

[0059] Specifically, the body side plate portion 110A of the first packaging material 100A and the body side plate portion 220A of the second packaging material 200A are slidably connected in the X direction, with corners 102A and 202A moving toward and away from each other. Similarly, the body side plate portion 120A of the first packaging material 100A and the body side plate portion 210B of the second packaging material 200B are slidably connected in the Y direction, with corners 102A and 202B moving toward and away from each other.

[0060] Furthermore, the body side plate portion 110B of the first packaging material 100B and the body side plate portion 220B of the second packaging material 200B are slidably connected in the X direction, with corners 102B and 202B moving toward and away from each other. Similarly, the body side plate portion 120B of the first packaging material 100B and the body side plate portion 210A of the second packaging material 200A are slidably connected in the Y direction, with corners 102B and 202A moving toward and away from each other.

[0061] In this way, the size of the rectangular cylindrical packaging body 50 is changed as the corners 102 and 202 of the adjacent body side plates 110 and 120 of the first packaging material 100 and the body side plates 210 and 220 of the second packaging material 200 slide toward and toward each other.

[0062] [Effect] Next, the operation of this embodiment will be described.

[0063] As shown in Figure 6, the size of the rectangular cylindrical packaging body 50 in plan view changes as the corners 102 and 202 of the adjacent body side plates 110 and 120 of the first packaging material 100 and the body side plates 210 and 220 of the second packaging material 200 slide toward and toward each other. Therefore, the external size of the packaging body 50 in plan view can be changed. Thus, the size of the rectangular cylindrical packaging body 50 in plan view can be adjusted to match the external size of the product 80, which is an example of the object to be packaged, in plan view. Note that the solid line in Figure 6 represents the maximum size of the packaging body 50, and the dashed line (two-dot line) represents the minimum size of the packaging body 50.

[0064] Furthermore, as an example of how to use the packaging box 10 shown in Figure 11, first the worker places the product 80 on the bottom member 20. The worker then adjusts the size of the packaging body 50 on the floor to match the external dimensions of the product 80 in a plan view. Next, the worker holds the handle portion 90 of the packaging body 50 (see also Figures 5 and 6) and inserts the packaging body 50 onto the product 80 from above. The worker makes fine adjustments to the size of the packaging body 50 as needed. Finally, the worker places the lid member 30 over the product to complete the packaging.

[0065] In this way, multiple products 80 with different external shapes can be packaged in a single packaging 50. From another perspective, by using the packaging 50 of this embodiment, it is not necessary to prepare a separate packaging for each product 80 with a different external shape.

[0066] Here, we will explain the case where new products are delivered to a customer and old products are collected from the customer. If the packaging 50 of this embodiment is not used, the new products are packaged and transported in a dedicated packaging, and the dedicated packaging for the old products is also transported together. After the new products are delivered, the old products are packaged in the same dedicated packaging used for transport, collected, and transported. Also, when collecting the old products, the packaging that contained the new products is collected and transported together. Therefore, the dedicated packaging for each product, both old and new, is only used for one-way transport, and production costs, transportation costs, and disposal costs are incurred for each.

[0067] In contrast, when a new product is packaged in the packaging 50 of this embodiment, the old product to be collected can be packaged and collected in the same packaging 50. Therefore, when transporting the new product, there is no need to transport a separate packaging for the old product to be collected. Similarly, when collecting the old product, there is no need to transport a separate packaging for the new product. As a result, the packaging 50 is used for both the outward and return journeys, reducing production costs, transportation costs, and disposal costs.

[0068] Furthermore, as shown in Figures 1 to 4, the side panels 110 and 120 of the first packaging material 100 of the packaging body 50 in this embodiment have a double structure with inner panels 112 and 122 and outer panels 114 and 124. The side panels 210 and 220 of the second packaging material 200 are inserted into the gaps S1 and S2 between the inner panels 112 and 122 and the outer panels 114 and 124. Therefore, compared to the case where the side panels 110 and 120 of the first packaging material 100 consist of only one of the inner panels 112 and 122 or the outer panels 114 and 124, the unintentional detachment of the first packaging material 100 and the second packaging material 200 is suppressed.

[0069] Furthermore, in this embodiment, the rail sections 131 and 132 of the packaging body 50, which are aligned in the direction of contact and separation of the first packaging material 100, are inserted into slits 231 and 232, which are aligned in the direction of contact and separation of the second packaging material 200. Therefore, compared to the case where there are no rail sections 131 and 132, it is suppressed that the packaging body 50 may unintentionally come loose in the vertical direction when changing the size of its outer dimensions, or that it may swing up and down when lifted.

[0070] Furthermore, as shown in Figures 2 and 4, in the packaging body 50 of this embodiment, wide sections 133 and 134 are formed at the ends of the rail sections 131 and 132. Also, stepped sections 233 and 234 that bend downward in a Z shape are formed at the opening ends of the slits 231 and 232. Therefore, as the outer shape of the packaging body 50 is increased, the wide sections 133 and 134 of the rail sections 131 and 132 come into contact with the stepped sections 233 and 234, preventing them from coming loose. Thus, compared to the case where the width of the rail section is constant, the second packaging material 200 is less likely to come loose from the first packaging material 100 unintentionally. Consequently, for example, the effort required to reassemble the first packaging material 100 and the second packaging material 200 in the event of unintentional detachment is reduced. When disassembling the first packaging material 100 and the second packaging material 200, the rail sections 131 and 132 are moved downwards by the wide sections 133 and 134 of the rail sections 131 and 132, which allows the rail sections 131 and 132 to exit through the opening slits 235 and 236.

[0071] Furthermore, as shown in Figures 1, 5, and 6, in this embodiment, the worker lifts the packaging 50 by holding the handles 90 provided at the corners 102 and 202. Therefore, it is easier to lift the packaging 50 compared to when the worker grasps the upper end of the packaging 50 with their hand.

[0072] Furthermore, the handle portion 90 of the packaging body 50 in this embodiment is provided by attaching a plate-like member, created by folding a single piece of corrugated cardboard into an L-shape in plan view, to the corners 102 and 202 with adhesive and double-sided tape. Therefore, compared to the case where the corners are formed to provide the handle portion, it is easier to provide the handle portion 90 to the corners 102 and 202.

[0073] The bottom member 20 and the lid member 30 are prepared to match the size of the external dimensions of the product 80 to be packaged in a plan view. The packaging body 50 is prepared to match the size of the height of the product 80 to be packaged.

[0074] <Second Embodiment> Next, the packaging of this embodiment will be described. Note that the same reference numerals are used for the same components as in the first embodiment, and redundant explanations will be omitted or simplified.

[0075] As shown in Figure 7, the packaging body 53 of the second embodiment is a cylindrical member with a rectangular shape in plan view, comprising two first packaging materials 300A and 300B and two second packaging materials 400A and 400B.

[0076] Furthermore, the first packaging materials 300A and 300B of the packaging body 53 correspond to the first packaging materials 100A and 100B of the first embodiment, and the second packaging materials 400A and 400B correspond to the second packaging materials 200A and 200B of the first embodiment (see Figures 1 and 6, etc.). Also, as in the above embodiment, the first packaging material 300A and the first packaging material 300B are the same material except for their placement. Similarly, the second packaging material 400A and the second packaging material 400B are the same material except for their placement. The same applies to the components that make up each of them. Therefore, if there is no need to explain them separately, A and B may be omitted.

[0077] Furthermore, similar to the packaging body 50 in the first embodiment, the packaging body 53 becomes a packaging box when the bottom member 20 closes the lower opening of the packaging body 53 and the lid member 30 closes the lower opening of the packaging body 50 (see Figure 11).

[0078] The first packaging material 300 is an L-shaped member in plan view, with the body side plate portion 310 and the body side plate portion 320 connected at a corner portion 302. Similarly, the second packaging material 400 is an L-shaped member in plan view, with the body side plate portion 410 and the body side plate portion 420 connected at a corner portion 202. The first packaging materials 300A and 300B are arranged so that their corner portions 302A and 302B are located at one diagonal corner 54A and 54B of the rectangular packaging body 53 in plan view. The second packaging materials 400A and 400B are arranged so that their corner portions 402A and 402B are located at the other diagonal corner 55A and 55B of the rectangular packaging body 53 in plan view.

[0079] Note that the side panels 310A, 310B and 410A, 410B are examples of the first piece. Also, the side panels 320A, 320B and 420A, 420B are examples of the second piece. The side panels 310 and 320 of the first packaging material 300 have a double structure consisting of inner panels 112, 122 and outer panels 114, 124.

[0080] As shown in Figures 8 and 9, the inner plate sections 112 and 122 and the outer plate sections 114 and 124 are connected by rail sections 330. Rail sections 330 are members that extend laterally and are provided in the vertical intermediate portions of each of the gaps S1A, S1B, S2A, and S2B. Rail sections 330 are provided in two locations, spaced apart in the vertical direction (see Figure 9). Rail sections 330 are composed of a first L-shaped member 331 and a second L-shaped member 332 that extend laterally and have an L-shaped cross-section.

[0081] The first L-shaped member 331 is composed of a first horizontal portion 333 and a first vertical portion 335. One end of the first horizontal portion 333 is joined to the inner plate portions 112 and 122 with adhesive and double-sided tape, etc. The first vertical portion 335 extends upward from the other end of the first horizontal portion 333. The first vertical portion 335 is not joined to the outer plate portions 114 and 124.

[0082] Similarly, the second L-shaped member 332 is composed of a second horizontal portion 334 and a second vertical portion 336. One end of the second horizontal portion 334 is joined to the outer plate portions 214 and 224 with adhesive and double-sided tape, etc. The second vertical portion 336 extends downward from the other end of the second horizontal portion 334. The second vertical portion 336 is not joined to the inner plate portions 112 and 122.

[0083] The second vertical portion 336 of the second L-shaped member 332 is inserted between the first vertical portion 335 of the first L-shaped member 331 and the inner plate portions 112 and 122. Alternatively, the first vertical portion 335 of the first L-shaped member 331 is inserted between the second vertical portion 336 of the second L-shaped member 332 and the outer plate portions 114 and 124.

[0084] Therefore, in the packaging material 300, the inner plate portions 112, 122 and the outer plate portions 114, 124 of the body side plate portions 310, 320 are connected so that the outer plate portions 114, 124 can move vertically relative to the inner plate portions 112, 122.

[0085] As shown in Figure 9, slits 430 are formed in the body side plates 410 and 420 of the second packaging material 400. The slits 430 are provided in two locations, spaced apart in the vertical direction. The slits 430 are formed at the same height as the rail portion 330.

[0086] The rail portion 330 of the first packaging material 300 is inserted into the slit 430 of the second packaging material 400. Thus, the packaging body 53 is constructed such that the body side plate portions 310, 320 of the adjacent first packaging material 300 and the body side plate portions 410, 420 of the second packaging material 400 are slidably connected in the direction of contact and separation, with the corner portions 302, 402 moving toward and away from each other.

[0087] As shown in Figure 8, when the outer plate portions 114 and 124 move upward relative to the inner plate portions 112 and 122 of the first packaging material 300, a locking mechanism 450 is provided in the packaging body 53 that locks the sliding of the second packaging material 400 relative to the first packaging material 300.

[0088] The locking mechanism 450 is composed of an upper sawtooth portion 340 and a lower sawtooth portion 440 provided in the gaps S1A, S1B, S2A, and S2B. The upper sawtooth portion 340, which extends laterally, is joined to the upper edge portion 119 of the inner plate portions 112 and 122. The upper sawtooth portion 340 is composed of a row of inverted triangular teeth 342 that are convex on the lower side.

[0089] As shown in Figure 9, the upper edges 419 of the side plates 410 and 420 of the second packaging material 400 have lower sawtooth-shaped portions 440 formed thereon. The lower sawtooth-shaped portions 440 are composed of a series of triangular teeth 442 that are convex on the upper side.

[0090] As shown in Figure 10, when the outer plate portions 114 and 124 move upward relative to the inner plate portions 112 and 122 of the first packaging material 300, the second horizontal portion 334 of the second L-shaped member 332 contacts the upper surface of the inner wall of the slit 430 of the second packaging material 400. This causes the second packaging material 400 to move upward as well. When the second packaging material 400 moves upward, the lower sawtooth portion 440 of the second packaging material 400 engages with and locks into the upper sawtooth portion 340 of the inner plate portions 112 and 122 of the first packaging material 300.

[0091] [Effect] Next, the operation of this embodiment will be described.

[0092] As shown in Figure 7, the size of the rectangular cylindrical packaging body 50 is changed by the sliding of the corners 302, 402 of the body side plates 310, 320 of the first packaging material 300 and the body side plates 410, 420 of the second packaging material 400 in the direction of contact and separation. Therefore, the size of the outer dimensions of the packaging body 53 in plan view can be changed. Thus, the size of the rectangular cylindrical packaging body 53 in plan view can be adjusted to match the size of the outer dimensions of the product 80 (see Figure 6) in plan view.

[0093] Similar to the first embodiment, an example of how to use the packaging 53 is as follows: The worker places the product 80 (see Figure 6) on the bottom member 20 (see Figure 11). The worker then adjusts the size of the packaging 53 on the floor to match the external dimensions of the product 80 in a plan view. Next, the worker holds the handle portion 90 (see Figure 5) of the packaging 53 and inserts the packaging 53 onto the product 80 from above. The worker makes fine adjustments to the size of the packaging 53 as needed. Finally, the worker covers the product with the lid member 30 (see Figure 11) to complete the packaging.

[0094] As shown in Figures 8 to 10, in this embodiment, the rail portion 330 of the packaging body 53 has the second vertical portion 336 of the second L-shaped member 332 inserted between the first vertical portion 335 of the first L-shaped member 331 and the inner plate portions 112 and 122. Therefore, the rail portion 330 connects the inner plate portions 112 and 122 and the outer plate portions 114 and 124 of the body side plate portions 310 and 320 of the first packaging material 300 so that the outer plate portions 114 and 124 can move vertically relative to the inner plate portions 112 and 122.

[0095] As shown in Figure 10, when the outer plates 114 and 124 move upward relative to the inner plates 112 and 122, the second packaging material 400 also moves upward. When the second packaging material 400 moves upward, the lower sawtooth portion 440 of the second packaging material 400 engages with and locks into the upper sawtooth portion 340 of the inner plates 112 and 122 of the first packaging material 300. Then, while locked, the inner plates 112 and 122 also move upward.

[0096] As shown in Figure 9, when the packaging body 53 of this embodiment is placed on the floor or the like, the lower sawtooth-shaped portion 440 of the outer plate portions 114 and 124 of the body side plate portions 310 and 320 of the first packaging material 300 and the upper sawtooth-shaped portion 340 of the inner plate portions 112 and 122 are separated and not interlocked. Therefore, the corner portions 302 and 402 of the packaging body 53 slide in the direction of contact and separation, making it possible to change the size of the packaging body 53.

[0097] However, as shown in Figure 10, when a worker lifts the first packaging material 300 by holding the corners 302 (see Figure 7, etc.) of the outer plate portions 114 and 124 of the body side plate portions 310 and 320, the outer plate portions 114 and 124 move upward relative to the inner plate portions 112 and 122. This causes the lower sawtooth portion 440 of the second packaging material 400 to interlock with the upper sawtooth portion 340 of the inner plate portions 112 and 122, locking into place. Therefore, the corners 302 and 402 of the packaging body 53 do not slide in the direction of contact and separation (see Figure 6). In other words, the locking prevents the size of the packaging body 53 from being unintentionally changed. Therefore, for example, after adjusting the size of the packaging body 53 to match the external dimensions of the product 80 (see Figure 6) in a plan view, when inserting the packaging body 53 onto the product 80 from above by holding the handle portion 90 (see Figure 5) of the packaging body 53, unintended changes in the size of the packaging body 53 are suppressed.

[0098] In this way, compared to the case without the locking mechanism 450, unintended sliding of the package 53 when it is lifted is suppressed.

[0099] Furthermore, the upper sawtooth portion 340 and the lower sawtooth portion 440 of the locking mechanism 450 are provided in the gaps S1A, S1B, S2A, and S2B. Therefore, compared to the case where the locking mechanism is provided on the outside of the gaps S1A, S1B, S2A, and S2B, the locking mechanism is less visible from the outside of the packaging 53.

[0100] Similar to the first embodiment, the bottom member 20 and the lid member 30 are prepared in sizes corresponding to the external dimensions of the product 80 to be packaged in a plan view. The packaging body 50 is also prepared in sizes corresponding to the height of the product 80 to be packaged.
