Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a packaging material for a cooking device such as a pot or a frying pan.

[0002]

[Prior art]

 Manufacturers of kitchen appliances such as home pots and frying pans were put into cardboard boxes (inner boxes) for each product, and these boxes were put together in an outer box. Alternatively, a plurality of products were packed in an inner box while protecting them with a cushioning material so as not to damage the package, and the inner boxes were further packed in an outer box.

[0003] As described above, the manufacturer has sent a large number of products to a dealer via a distribution wholesaler in units of outer packaging boxes.

[0004]

[Problems to be solved by the invention]

 However, the order units ordered from dealers have become smaller due to inventory management and the speed of distribution. To deal with this, manufacturers are working to reduce the quantity of products packed in outer boxes, but there are limitations in terms of transportation efficiency.

[0005] On the other hand, at a wholesaler, it is necessary to send a small order unit from the dealer, so if the packaging unit of the outer box sent from the manufacturer does not match the order unit, a new order unit is added. They often repack as needed, and this additional work is a burden. At this time, the burden was also placed on the disposal of empty inner boxes and cushioning materials generated during repacking.

[0006] Such a problem of the disposal of materials is the same at the store, but especially at the mass retailer, the inner box is considered in view of the display efficiency except for the case where each inner box has a display effect that is offset printed. In many cases, large quantities of waste, cushioning and packing materials are discarded. For each inner box alone, it takes time to disassemble the box and compress it so that it does not become bulky.From the viewpoint of environmental issues that have been widely handled in recent years, it is important to pay However, each consumer is burdened with the process, and does not want to take out the packaging materials.

[0007] As described above, with respect to a cooker as a household commodity in which the minimum unit of order is one, a packaging material such as an inner box and a cushioning material which requires a minimum amount of packaging material and has a light burden of disposal is desired. It is rare.

[0008] In view of the above problems, the object of the present invention is to reduce the amount of materials required as a packaging material for individual packaging of a cooking device, assemble and disassemble easily, and reduce the burden of disposal. It is to provide a packaging material which is reduced.

[0009]

Are arranged side by side at predetermined intervals in parallel with each other in the sheet longitudinal direction, and are individually packaged for cookers surrounding the cooker to be packed while being folded along the fold line, wherein the corrugated cardboard sheets have opposite short sides. In the vicinity of the hand side, an engaging portion for maintaining the tubular structure by engaging with each other to form one corner of the rectangular tubular structure is provided, and a predetermined position at both side open ends of the tubular structure is provided. A fold line and / or a cut line for folding the cardboard end inward to form a support portion for supporting the cooking device from the outer peripheral side is provided.

[0010] Further, in the packaging material according to the invention of claim 2, in the packaging material of claim 1, the supporting portion is formed such that both side edges of each opening end of the tubular structure are formed of the cooking device. It is formed at four points folded into the inner position in contact with the side surface.

According to a third aspect of the present invention, there is provided the packaging material according to the first aspect, wherein the support portion is provided on a side of each opening end of the cylindrical structure facing the bottom of the cooker. Each of the four corners is formed by a cut edge protruding inward by folding in the opposite direction, and these corners support the cooker in four directions. .

Further, the packaging material according to the invention of claim 4 is the packaging material according to claim 1, wherein the packaging target is a cooker having a grip portion protruding upward, and the cardboard sheet. According to the present invention, a bent piece that is bent upward corresponding to the protrusion of the grip portion is formed in advance in a region of the upper surface of the prismatic tubular structure that abuts on the grip portion by a cut line.

According to a fifth aspect of the present invention, there is provided the packaging material according to the fourth aspect, wherein the packaging target is a stacked body of a plurality of cookers having a grip portion protruding upward. In the corrugated cardboard sheet, a cutout portion that allows the grip portion to be fitted is formed in advance in a region of the bottom surface of the tubular structure that contacts the grip portion.

According to a sixth aspect of the present invention, there is provided the packaging material according to the first aspect, wherein the packaging object is a cooker having a bar-shaped grip portion protruding to the side, and the cardboard sheet. In the above, a through hole is formed in advance on a side surface of the prismatic tubular structure so that the gripper can protrude outside the tubular structure.

[0015]

[Embodiment of the invention]

 In the packaging material of the present invention, first, a substantially rectangular corrugated cardboard sheet is folded around a cooker so as to form a square tubular structure, thereby accommodating the cooker in the tubular structure. At this point, both sides of the tubular structure are open, but furthermore, the supporting portion for supporting the cooking device from the outer peripheral side by folding the cardboard end inward along a predetermined folding line or cut line at both open ends of the tubular structure. Is formed, and the package can be placed in a fixed position.

As described above, in the packaging material of the present invention, the packaging material for wrapping the cooking device can be constituted only by folding one substantially rectangular cardboard sheet along the fold line. Therefore, the packaging box can be assembled at the same time as the packaging of the product simply by forming only the fold line and the score line in advance, and the operation and cost from the assembly of the box to the packaging are greatly simplified.

Further, the packaging material according to the present invention can be easily developed into a single sheet simply by opening the fold in the opposite direction to the packaging, so that not only the packaging but also the disassembly process is much easier than in the past. However, the waste after disassembly is only lightly corrugated cardboard, which is a very light burden. Moreover, in the packaging material of the present invention, since the edges and corners folded inward support and fix the cooker inside, the filling of the buffer material, which becomes a burden on the disposal process later, as in the related art, is performed. There is no need to do so, making packing and material disposal easier.

In the packaging material of the present invention, the short side of the cardboard sheet is set to be longer than the maximum width of the target cooking device in order to completely surround the cooking device in a tubular structure. Therefore, after the cylindrical structure is formed, even after the cardboard end is folded inward along the predetermined fold line or cut line at the opening end on both sides, the area outside the fold is shorter than the maximum width of the cooking device. Since the length in the hand direction is maintained in the axial direction of the tubular structure, the part protruding from the packed cooker body holds the surrounding space and protects the cooker as a buffer against external force. It has the function to do.

Further, the cardboard sheet of the present packaging material has an engaging portion for maintaining the tubular structure by forming a corner of the rectangular tubular structure by engaging with each other near the opposite short sides on both sides. However, the engaging part is relatively easy to engage when packing the cooker and releasing when disassembling it, but it is easy to maintain the packing state during transportation, etc. What does not enter the release state is desired.

For example, it is easy to use an insertion lock mechanism which is generally widely used for locking a lid of a cardboard box. Alternatively, a configuration in which the glue margins are simply extended to the short sides on both sides and adhered and fixed to each other is also a relatively simple engagement method since it takes time to peel off the area at the time of disassembly.

Further, as a configuration of the support portion of the present packaging material, a folded portion and an angle may be appropriately set according to the shape of the cooking device to be packaged. Most of the general cookers have a deep body as a main body and an R-shaped bottom. Therefore, in order to hold the cooker well without moving and rattling in the packaging material, it is most efficient to support the main body from four directions at substantially equal angular intervals from the outer peripheral side.

However, if the crease line of the corrugated cardboard sheet is set so that the space between the side surfaces and the upper and lower surfaces in the tubular structure substantially matches the width and height of the cooking device main body and there is no room for rattling inside, the support is provided. As long as the part restricts movement only in the front-rear direction toward the opening on both sides of the tubular structure, the cooker can be held sufficiently well in the packaging material without rattling.

For example, if both side edges of each open end of the tubular structure are folded into an inner position in contact with a side surface of the cooking device, four points which are contact points of the edge with the side surface of the cooking device are supported. This makes it possible to regulate the movement of the cooker in the packaging material in the front-rear direction and to hold the cooker satisfactorily.

Alternatively, if the four corners of each open end of the cylindrical structure facing the bottom of the cooker are folded in opposite directions to project inward, the protrusions project inward. The sharp point of the corner formed by the cut edge supports the front and back of the cooker on the lower left and right sides and regulates the movement of the controller in the front and rear direction, so that the cooker can be satisfactorily prevented from rattling in the packaging material. Can hold. In this case, since the support is made at the pointed corners, the mechanical strength of the support portion is greater than the support by the contact at the edge, and a more stable holding state can be obtained.

There are various shapes of cookers. For example, in the case of a two-handed pan, a grip portion protruding upward is provided at both sides of the controller main body facing each other. Therefore, when the cooking device to be packaged has a grip portion protruding upward, such as a two-handed pan, the cardboard sheet has an area in contact with the grip portion on the upper surface of the square tubular structure. It is desirable that a bent piece bent upward in accordance with the protrusion of the grip portion is formed in advance by a cut line.

[0026] With this, even if the cooking device main body is surrounded by a cardboard sheet along its upper surface, the holding portion can escape upward without affecting the upper surface of the tubular structure. The extra space that can cause the collapse of the load such as deformation or crushing can be packed in the tubular structure without being created above the cooker. Further, since the gripping portions projecting upward to escape are locked to the packaging material in the direction in which the gripping portions face each other, the cooker is more reliably held in the packaging material.

[0027] In the case of the cooking device packed with the packaging material of the present invention, if the bottom surface of another tubular structure is brought into contact with the upper surface of the tubular structure, the cooker can be easily formed without forming a bulky or useless space. Layered on. Therefore, it can be easily loaded into an arbitrary number unit, and the packing and repacking can be easily and compactly performed with almost no waste material.

Further, when a plurality of cookers, such as a two-handed pan, having upwardly protruding gripping portions are stacked, the gripping portions protruding from the lower cylindrical structure on the bottom surface of the cylindrical structure. A notch may be formed in advance in a contact area so that the grip can be fitted. As a result, the packaging materials are compactly stacked without being bulky between the upper and lower portions, and the upper and lower grip portions and the notch portions are in a state of being easily locked to each other, so that an effect of preventing collapse of the load can be expected.

When the cooking device to be packaged has a stick-shaped gripping portion protruding laterally from the cooking device body such as a one-handed pan, a frying pan, and an egg-baked pan, the cardboard sheet has a square shape. A through hole may be formed in advance on the side surface of the tubular structure so that the gripping portion can protrude outside the tubular structure. If the corrugated cardboard sheet is first folded after passing the rod-shaped grip portion into the through hole, the grip portion does not become an obstacle in the step of forming the rectangular tubular structure.

Further, in the packaging material of the present invention, a region facing the upper surface or the bottom surface of the cooker, which is the upper or lower surface of the tubular structure of the cardboard sheet, at least corresponds to the outer peripheral region of the cooker. The shape may be any shape as long as it can be pressed into contact with the cooker. For example, the cooker may be formed into a substantially frame shape with an opening at the center so that a part of the cooker as a product can be confirmed from outside the packaging material.

【Example】

 FIG. 1 shows a packaging material for a cooking appliance according to a first embodiment of the present invention in the case of a two-handed pan packaging. FIG. 1A is a developed plan view showing a configuration of a packaging material according to the present embodiment, and FIG. 1B is a schematic perspective view showing a rectangular tube structure in a process of packing a two-handed pan with the packaging material. () Is a schematic perspective view showing a state in which individual packing of the two-handed pan is completed with the present packaging material.

The packaging material according to the present embodiment is composed of one substantially rectangular cardboard sheet 1 whose short length is longer than the maximum width of the two-handed pan to be packed. Crease lines (6A, 6B, 6C, 6D) for forming the bottom surface 2, both side surfaces (4, 5), and the top surface 8 of the structure are provided at predetermined intervals in parallel with each other in the sheet longitudinal direction.

In the vicinity of the opposite short sides of the corrugated cardboard sheet 1, a rectangular tube structure formed around the cooker while being sequentially folded along the fold lines (6 A to 6 D) is held. For this purpose, a slit 10x and a plug projection 10y for a plug lock mechanism conventionally used for opening and closing a general box cover are formed. These plug-in lock mechanisms maintain the cylindrical structure by engaging with each other at a fold line 6A to form one corner of the cylindrical structure.

The corrugated cardboard sheet 1 has both side surfaces (4, 5) in order to later fold the corrugated cardboard ends 11 of the both side openings of the tubular structure inward to support the cooking device body from the outer peripheral direction. ), Two fold lines 7x formed parallel to the longitudinal direction of the corrugated cardboard sheet, and a pair of diagonal fold lines 7y formed on both sides of each fold line 7x and accompanying the fold along the fold line 7x. There are four sets.

Further, the present embodiment is a packaging material for a two-handed pan 15, and a pair of gripping portions 16 projecting upward when the two-handed pan 15 is surrounded can escape without affecting the cylindrical shape of the packaging material. As described above, a pair of cut lines 8 that form bent pieces t1 in which the gripping portion contact area on the upper surface 3 is lifted up by the gripping portion 16 in a flap shape and bent upward is provided.

In addition, the width (the longitudinal direction of the cardboard sheet) of both sides (4, 5) of the cylindrical structure of the cardboard sheet 1 substantially matches the height of the main body of the two-handed pan 15 to be packed, and the bottom surface 2 and the upper surface 3 The width (in the longitudinal direction of the corrugated cardboard sheet) was also set to substantially match the maximum width of the main body excluding the gripping portion of the two-handed pan 15.

Thus, in the tubular structure of the cardboard sheet 1 surrounding the pan 15 in both hands, the protrusion of the grip portion 16 is released upward, and the cause of the collapse or the collapse of the load at the time of later loading above the pan main body. Thus, the two-handed pan 15 is wrapped in a direction perpendicular to the facing direction of the pair of gripping portions 16 without any space in the vertical and horizontal directions without forming an extra space.

The packing of the two-handed pan 15 by the cardboard sheet 1 having the above configuration is performed as follows. First, a pair of grippers 16 is placed on the bottom surface 2 of the cardboard sheet 1 in a direction along the short direction of the cardboard sheet 1, and then the fold lines (A, 6B, 6C, 6D) are sequentially formed. 1b so as to surround the pan 15 in both hands, thereby forming a square tubular structure as shown in FIG. 1 (b), and engaging the slit portion 10x of the insertion lock mechanism with the insertion projection 10y. In this state, the two-handed pan 15 is almost completely accommodated in the cylindrical structure, and the holding state in which the movement in the vertical and horizontal directions is restricted in the cylindrical structure.

Next, the left and right cardboard ends 11 on both side surfaces (4, 5) are folded inward along the fold lines (7x, 7y) at the opening portions on both sides of the cylindrical structure. As a result, as shown in FIG. 1 (c), the cardboard end 11 comes into contact with the side surface of the two-handed pot main body and serves as a supporting portion for supporting the two-handed pot 15 from the front and rear directions. Is regulated by four points, two points each on the left and right.

Therefore, the movement of the two-handed pan 15 in all directions within the packaging material is finally restricted by the support state at the cardboard end 11, and the two-sided pan 15 is packed tightly in a substantially box shape. The state is maintained well without rattling.

With the above operation, the packing of the two-handed pan 15 by the cardboard sheet 1 is completed, and the both-handed pans are individually packed products 17. In this state, the cardboard end 11 folded inside the opening end of the tubular structure. Since the peripheral portion 12 other than the above maintains the length of the cardboard sheet in the transverse direction longer than the maximum width of the pot body in the axial direction of the tubular structure, the portion 12 protruding from the packed pot body is It occupies the surrounding space and functions to protect the two-handed pan 15 as a buffer against external force.

In the cardboard sheet 1 of the present embodiment, substantially trapezoidal cutouts 9 are formed on the bottom surface 2 at both end positions corresponding to the bent pieces t 1 on the upper surface 8. The notch 9 allows the packaged products 17 in the two-handed pan 15 to be packed in plurals as shown in FIG. Since the gripping portion 16 that comes out can be fitted into the notch 9 on the bottom surface of the upper packaged product 17 and protruded, the upper and lower packaged products are compactly contacted with one bottom surface and the other top surface without any gap. Can be loaded on

The fitting of the lower product gripping portion 16 to the notch 9 of the upper product is such that the upper and lower products are locked with each other, so that the lower product gripping portion 16 also has an effect of preventing collapse of the load after loading. We can expect it.

Further, when unpacking, the two-handed pan can be taken out simply by releasing the engagement state of the insertion lock mechanisms (10x, 10y), and at the same time, the packaging material is spread on one cardboard sheet 1. Since it is in a disassembled state, there is no need for labor for disassembly and compression as in the past. Also, since no bulky waste such as buffer material is produced, disposal is easy.

Next, a packaging material for a cooking appliance according to a second embodiment of the present invention is shown in FIG. FIG. 3A is an exploded plan view showing the configuration of the packaging material according to the present embodiment, and FIG. 3B is a schematic perspective view showing a prismatic tube structure in a frying pan packaging process using the packaging material. () Is a schematic perspective view showing a state in which individual packaging of frying pans is completed with the present packaging material.

The packaging material according to the present embodiment is composed of one substantially rectangular corrugated cardboard sheet 21 whose short length is longer than the maximum width of the frying pan body 35, and the bottom surface 22 of the rectangular tube structure when packing the cooking device. Fold lines (26A, 26B, 26C, 26D) for forming both side surfaces (24, 25) and the upper surface 28 are provided at predetermined intervals in parallel with each other in the sheet longitudinal direction.

The present packing material is for packing only the frying pan main body 35 having one bar-shaped grip portion 36 protruding from the side surface. A through hole 34 for projecting the rod-shaped grip 36 to the outside is formed.

In the vicinity of the opposite short sides of the corrugated cardboard sheet 21, a rectangular cylindrical structure formed around the frying pan main body 35 while being sequentially folded along the fold lines (26 A to 26 D) is held. As in the first embodiment, a slit 30x and an insertion protrusion 30y for the insertion lock mechanism similar to those of the first embodiment are formed. These insertion lock mechanisms maintain the cylindrical structure by engaging with each other at a fold line 26A to form one corner of the cylindrical structure.

Also, in the corrugated cardboard sheet 21 of the present embodiment, similarly to the first embodiment, the corrugated cardboard ends 31 of the opening portions on both sides of the tubular structure are later folded inward to support the cooking device main body from the outer peripheral direction. In order to form a support portion, two fold lines 27x are formed on both side surfaces (24, 25) in parallel with the longitudinal direction of the cardboard sheet, and a pair of fold lines 27x are formed on both sides of each fold line 27x. Four sets of oblique fold lines 27y accompanying the folding along the line 27x are provided.

The width (longitudinal direction of the cardboard sheet) of both side surfaces (24, 25) of the cylindrical structure of the cardboard sheet 21 is set to a size substantially matching the height of the frying pan body 35 to be packed, and the bottom surface 22 and the top surface The width (the longitudinal direction of the corrugated cardboard sheet) of 23 also has a dimension substantially matching the maximum width of the frying pan main body 35 excluding the gripping part, so that the frying pan main body 35 can be moved with the rod-shaped gripping part 36 protruding from the through hole 34. In the cylindrical structure of the enclosed cardboard sheet 21, the same direction as the protruding direction of the grip portion 36 is formed without forming an extra space above the frying pan main body, which may cause collapse or collapse of a later load. As a result, the frying pan body 35 is wrapped almost completely in the vertical and horizontal directions.

The packing of the frying pan main body 35 with the cardboard sheet 21 having the above configuration is performed as follows. First, the frying pan main body 35 is placed on the bottom surface 22 of the corrugated cardboard sheet 21 while the rod-shaped gripping portion 36 is passed through the through hole 34 while the side surface 27 of the corrugated cardboard sheet 21 is folded up at the fold line 26C. It is placed with its bottom facing upward and folded along the fold lines (26A, 26B, 26C, 26D) so as to surround the frying pan main body 35, and as shown in FIG. Form the structure.

When the short sides on both sides of the cardboard sheet 21 abut against each other, the slit structure 30x and the insertion protrusion 30y of the insertion lock mechanism are engaged with each other to fix the cylindrical structure. As a result, the frying pan main body 35 is almost exactly housed in the cylindrical structure, and the holding state is restricted in the vertical and horizontal movements in the cylindrical structure.

Next, the left and right cardboard ends 31 on both side surfaces (24, 25) are folded inward along the fold lines (27x, 27y) at both side openings of the tubular structure. As a result, as shown in FIG. 3 (c), the cardboard end 31 comes into contact with the side surface of the frying pan main body 35 and serves as a supporting portion for supporting the frying pan main body 35 from the front-rear direction (opening directions on both sides of the cylindrical structure). The movement of the frying pan body 35 back and forth is regulated by four points, two points each on the left and right.

Therefore, the movement of the frying pan main body 35 in all directions within the packaging material is finally restricted by the support state at the cardboard end 31, and the frying pan main body 35 is tightly packed in a substantially box shape. It is in a state of being held well without rattling inside.

With the above operation, the packing of the frying pan main body 35 with the cardboard sheet 21 is completed, and the frying pan individual packed product 37 is obtained. In this state, the parts other than the cardboard end 31 folded inside the opening end of the cylindrical structure are provided. Since the peripheral portion 32 maintains the length of the cardboard sheet in the transverse direction longer than the maximum width of the frying pan body 35 in the axial direction of the tubular structure, the peripheral portion 32 protrudes from the packed frying pan body 35 in the outer circumferential direction. Reference numeral 32 occupies the surrounding space, and functions to protect the frying pan main body 35 as a buffer against external force.

The corrugated cardboard sheet 21 according to the present embodiment has a pair of cut lines 28 such that a substantially T-shaped bent piece t2 that can be raised and lowered in a flap shape is formed on both ends of the upper surface 23. And a trapezoidal notch 29 having a width smaller than the maximum interval between the pair of cut lines 28 is formed at both ends of the bottom surface 22 at positions corresponding to the substantially T-shaped bent pieces t2. Have been.

When these packaged products 37 are stacked vertically in a package, etc., the upper and lower packaged products 37 can be compactly loaded by contacting one bottom surface and the other top surface without any gap. At this time, as shown in FIG. 4, the bent product t2 on the upper surface 23 of the lower packaging material is lifted upward and fitted into the notch 29 on the bottom surface 22 of the upper packaging material to lock the upper and lower products together. It is possible to prevent the collapse of the load after loading.

In the packaging material of this embodiment, the upper surface 22 of the cardboard sheet 21 has a substantially frame shape having an opening 32 at the center. Through the opening 32, the inner surface of the frying pan main body 35 can be checked from the outside while being packed.

The configuration of the packaging material shown in the above second embodiment is not limited to the frying pan, but can be set such as a one-handed pan or an egg fried bread by appropriately setting the fold line position according to the depth and width of the object. It can be applied to various cookers having a stick-shaped gripping portion protruding in the direction.

Next, as a third embodiment of the present invention, a packaging material having a different configuration of the support portion and an engagement portion from those of the first and second embodiments is shown in FIG. Show. FIG. 5A is a developed plan view showing a configuration of the packaging material according to the present embodiment, and FIG. 5B is a schematic perspective view showing a rectangular tube structure in a process of packing a two-handed pan with the packaging material. (c) is a schematic perspective view showing a completed state of the individual packing of the two-handed pan with the present packaging material.

In the packaging material according to the present embodiment, a short rectangular length is constituted by one substantially rectangular cardboard sheet 41 longer than the maximum width of the two-handed pan 15 to be packed. Crease lines (46A, 46B, 46C, 46D) for forming the bottom surface 42, both side surfaces (44, 45), and the top surface 48 of the cylindrical structure are provided at predetermined intervals in parallel with each other in the sheet longitudinal direction. is there.

The opposite short sides of the corrugated cardboard sheet 41 are engaged with each other to hold the rectangular tubular structure formed by surrounding the cooker while sequentially folding along the fold lines (46A to 46D). In this embodiment, a glue surrogate surface 50 is provided at one end of the cardboard sheet 41, and the other end of the glue surrogate surface 50, here, the end of the upper surface 43, is provided with an adhesive. It was assumed that they were stacked and bonded. The glue surplus surface 50 and the end of the upper surface 43 are bonded to each other, and at the same time, form one corner of the cylindrical structure at the fold line 46A to maintain the cylindrical structure.

The corrugated cardboard sheet 41 has two corners on both sides of the bottom surface 42 so that the corrugated cardboard ends of the openings on both sides of the tubular structure are later folded inward to form corners for supporting the cooking device body from the outer peripheral direction. Are four pairs of fold lines 47x along the fold lines 46B and 46C, and four cut lines 47y orthogonal to the fold lines (46B and 46C) respectively between the pair of fold lines 47x. Is provided.

As in the first embodiment, the pair of gripping portions 16 projecting upward when surrounding the pan 15 are held on the upper surface 43 so as to escape without affecting the cylindrical shape of the packaging material. A pair of cut lines 48 for forming bent pieces t3 that are lifted up in a flap shape by the grip 16 and bent upward are provided in the part contact area. Further, cutout portions 49 are formed at both side edges of the bottom surface 42 at positions facing the bent pieces t3, and when the packed individual products are stacked up and down, the cutout portions 49 on the upper side are formed. The upper and lower products are stacked without any gap by fitting the gripping portion 16 of the lower product to the lower product.

Also in the cardboard sheet 41 of this embodiment, the width (both in the longitudinal direction) of both side surfaces (44, 45) in the tubular structure substantially matches the main body height of the two-sided pan 15 to be packed, and the bottom surface 42 The width of the upper surface 43 (longitudinal direction of the cardboard sheet) is also substantially equal to the maximum width of the main body excluding the gripping portion of the two-handed pan 15, so that when the two-handed pan 15 is surrounded by a cylindrical structure, the gripping portion 16 is formed. Of the pair of gripping portions 16 without releasing extra space above the main body of the pot, which may cause collapse or collapse of the load. It is possible to wrap the pan 15 with almost no gap in the vertical and horizontal directions in the direction perpendicular to the pan.

The packing of the two-handed pan 15 by the cardboard sheet 41 having the above configuration is performed as follows. First, after the pair of grippers 16 are placed on the bottom surface 42 of the cardboard sheet 41 in a direction along the short direction of the cardboard sheet 41, the folding lines (46A, 46B, 46C, 46D) are sequentially formed. 5b so as to surround the pan 15 in both hands, form a square tubular structure as shown in FIG. 5 (b), apply an adhesive on the adhesive margin surface 50, and place the upper surface 43 thereon. If they are glued together, the two-handed pan 15 is almost exactly accommodated in the tubular structure, and the holding state in which movement in the vertical and horizontal directions is restricted in the tubular structure.

Next, in the openings on both sides of the cylindrical structure, the four corners of the fold line 27x formed along the two corners on both sides of the bottom surface 42 are respectively folded, and the corners are projected inward in the opposite direction. As a result, as shown in FIG. 5 (c), the sharp point 51 formed from the cut edge of the cut line 47y on the opening side of the cylindrical structure comes into contact with the side surface of the two-handed pot main body, and the two-handed pot 15 is moved from the outer circumferential front and rear direction. It supports and regulates the forward and backward movement of the two-handed pan 15 within the packaging material at four points, two on each side.

Accordingly, the movement of the two-handed pan 15 in all directions within the packaging material is finally restricted by the support state of the corner point 51, and the two-sided pan 15 is tightly packed in a substantially box shape. The state is maintained well without rattling.

When unpacking, the pot can be easily taken out simply by peeling the adhesive margin portion 50 from the upper surface 43, and at the same time, the packaging material is spread on one cardboard sheet 41 to be disassembled.
