Description

[Technical Field]

[0001] The present invention relates to a package and a packaging method. [Background technology]

[0002] BACKGROUND ART A package is known that includes a cardboard box and a plurality of polystyrene foam sheets as cushioning material sandwiched between the cardboard box and a hot plate.

[0003] The hot plate is packaged by attaching a polystyrene foam to the hot plate and placing the hot plate and the polystyrene foam together in a cardboard box so that the polystyrene foam contacts the inner surface of the cardboard box. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 6-24470 Summary of the Invention [Problem to be solved by the invention]

[0005] Some appliances operate loads using power supplied from a power cord. For example, a cooking appliance is an appliance that uses power supplied from a power cord to operate a heat source such as a heater, magnetron, or induction heating coil to heat an object to be heated.

[0006] Generally, power cords are preferably flexible for easy handling. To achieve flexibility, power cords are provided with a flexible covering or exterior that encases the linear conductors. Such flexible covering or exterior is made of, for example, vinyl containing a plasticizer.

[0007] If a power cord is in contact with polystyrene foam for a long period of time, the plasticizer contained in the power cord will migrate into the polystyrene foam. When the plasticizer migrates into the polystyrene foam, the polystyrene foam will deteriorate and adhere to the power cord. The deteriorated polystyrene foam will lose its function as a cushioning material, and a power cord with polystyrene foam attached to it will reduce the commercial value of the equipment.

[0008] To address this issue, conventional methods have included packaging the power cord that can be removed from the device in a polyester bag to prevent contact between the power cord and the polystyrene foam, providing the device with a power cord winding device (a so-called cord reel) to prevent contact between the power cord and the polystyrene foam, or packaging only the power cord that comes out directly from the device in a polyester bag to prevent contact between the power cord and the polystyrene foam.However, these measures result in an increase in the size and weight of the device due to the inclusion of an internal cord reel, and also increase the cost of the bags in which the power cord is packed and the labor costs for packing the power cord into the bags.

[0009] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a packaging body and a packaging method that can easily and inexpensively prevent contact between the power cord of a device and a cushioning material. [Means for solving the problem]

[0010] In order to solve the above-mentioned problems, a packaging body according to an embodiment of the present invention includes a packaging box having a bottom wall, side walls rising from the periphery of the bottom wall, and a lid that is continuous with the upper edge of the side wall and closes an upper opening of the side wall; a sheet that wraps around an appliance having a main body and a power cord extending from the main body; at least one lower cushioning material that is sandwiched between the main body around which the sheet is wrapped and the bottom wall, and between the main body around which the sheet is wrapped and the side wall; and a cushioning material that is sandwiched between the main body around which the sheet is wrapped and the side wall, and between the main body around which the sheet is wrapped and the lid. and at least one upper cushioning material attached to the sheet, wherein the sheet has an excess portion reaching the at least one upper cushioning material, the at least one upper cushioning material having an upper recess that defines an upper storage space between the at least one upper cushioning material and the packaging box, and at least a portion of the power cord is stored in the upper recess via the excess portion of the sheet, or the at least one lower cushioning material having a lower recess that defines a lower storage space between the at least one lower cushioning material and the packaging box, and at least a portion of the power cord is stored in the lower recess via the excess portion of the sheet.

[0011] In addition, in order to solve the above-mentioned problems, a packaging method according to an embodiment of the present invention includes preparing a packaging box having a bottom wall, side walls rising from the periphery of the bottom wall, and a lid that is continuous with the upper edge of the side wall and closes the upper opening of the side wall, placing at least one lower cushioning material on the bottom of the packaging box, laying a sheet on top of the at least one lower cushioning material, placing a device having a main body and a power cord extending from the main body on the sheet so that the at least one lower cushioning material is sandwiched between the main body and the bottom wall and between the main body and the side wall, and storing the device in the packaging box, wrapping the sheet around the device, covering the main body with at least one upper cushioning material while avoiding any excess part of the sheet, covering the excess part with an upper recess that defines an upper storage space between the at least one upper cushioning material and the packaging box, storing at least a portion of the power cord in the upper recess, and closing the lid. [Brief explanation of the drawings]

[0012] [Figure 1] 1 is an exploded perspective view of a package according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0013] A package and a packaging method according to the present invention will be described below with reference to Fig. 1. Note that the same or corresponding components are designated by the same reference numerals throughout the drawings.

[0014] FIG. 1 is an exploded perspective view of a package according to an embodiment of the present invention.

[0015] As shown in FIG. 1, the packaging body 1 of this embodiment includes a packaging box 2, a sheet 5 wrapped around the equipment 3, a lower cushioning material 6 sandwiched between the equipment 3 wrapped in the sheet 5 and the packaging box 2, and an upper cushioning material 7 sandwiched between the equipment 3 wrapped around the sheet 5 and the packaging box 2.

[0016] The packaging box 2 is a so-called cardboard box. The packaging box 2 is made by folding and assembling a box blank (also simply called a "blank") along the lines. The box blank is formed by punching out a single cardboard sheet made of paper using a cutting die or the like. The cardboard sheet is, for example, a double-sided cardboard sheet made by bonding together a corrugated core, a front liner, and a back liner.

[0017] The packaging box 2 includes a bottom wall 21, side walls 22 rising from the periphery of the bottom wall 21, and a lid 25 that is continuous with the upper edge of the side walls 22 and closes an upper opening 23 of the side walls 22. The packaging box 2 is a hexahedron having a bottom surface 2a, a top surface 2b, a front surface 2c, a back surface 2d, and a pair of side surfaces 2e1 and 2e2. The bottom surface 2a, the top surface 2b, the front surface 2c, the back surface 2d, and the pair of side surfaces 2e1 and 2e2 are square or rectangular, i.e., rectangular. The shapes of the opposing pairs of surfaces, for example, the shape of the bottom surface 2a and the shape of the top surface 2b, are the same, i.e., congruent. In other words, the packaging box 2 is a rectangular parallelepiped or cube. The top surface 2b of the packaging box 2, i.e., the upper opening 23 that is revealed when the lid 25 is opened, is also rectangular.

[0018] The outer surface of the bottom wall 21 is the bottom surface 2a of the packaging box 2, the outer surfaces of the side wall 22 are the front surface 2c, back surface 2d, one side surface 2e1, or the other side surface 2e2 of the packaging box 2, and the outer surface of the lid 25 is the top surface 2b of the packaging box 2. For ease of explanation, the side wall 22 on the front surface 2c is referred to as the front wall 25F, the side wall 22 on the back surface 2d is referred to as the back wall 25B, the side wall 22 on one side surface 2e1 is referred to as the left side wall 25L, and the side wall 22 on the other side surface 2e2 is referred to as the right side wall 25R.

[0019] For ease of explanation, the inner surface of the bottom wall 21 will be referred to as the inner bottom surface of the packaging box 2, the inner surface of the front wall 25F will be referred to as the inner front surface of the packaging box 2, the inner surface of the back wall 25B will be referred to as the inner back surface of the packaging box 2, the inner surface of the left side wall 25L will be referred to as the inner left side surface of the packaging box 2, the inner surface of the right side wall 25R will be referred to as the inner right side surface of the packaging box 2, and the inner surface of the lid 25 will be referred to as the ceiling surface of the packaging box 2. The inner front, inner back, inner left side, and inner right side will also be simply referred to as inner surfaces. In other words, the packaging box 2 has an inner bottom surface behind the bottom surface 2a, a ceiling surface behind the top surface 2b, and four inner surfaces behind the front surface 2c, back surface 2d, and pair of side surfaces 2e1 and 2e2.

[0020] The package 1 includes a front flap 26F foldably connected to the upper edge of the front wall 25F, a rear flap 26B foldably connected to the upper edge of the back wall 25B, a left flap 26L foldably connected to the upper edge of the left side wall 25L, and a right flap 26R foldably connected to the upper edge of the right side wall 25R. The lid 25 is made up of four flaps 26F, 26B, 26L, and 26R that are folded and overlapped to cover the upper opening 23 of the side wall 22.

[0021] The width of the left flap 26L extends along the entire length of the upper edge of the left side wall 25L, and the width of the right flap 26R extends along the entire length of the upper edge of the right side wall 25R. The sum of the protruding length of the left flap 26L based on the upper edge of the left side wall 25L and the protruding length of the right flap 26R based on the upper edge of the right side wall 25R is equal to or greater than the entire length of the upper edge of the front wall 25F and the entire length of the upper edge of the rear wall 25B. In other words, when the left flap 26L and the right flap 26R are folded to cover the upper opening 23 of the side wall 22, the upper opening 23 of the side wall 22 is closed. In this embodiment, the protruding lengths of the left flap 26L and the right flap 26R are half the entire length of the upper edge of the front wall 25F and half the entire length of the upper edge of the rear wall 25B.

[0022] The width of the front flap 26F extends along the entire length of the upper edge of the front wall 25F, and the width of the rear flap 26B extends along the entire length of the upper edge of the rear wall 25B. The sum of the protruding length of the front flap 26F based on the upper edge of the front wall 25F and the protruding length of the rear flap 26B based on the upper edge of the rear wall 25B is smaller than the entire length of the upper edge of the left side wall 25L and the entire length of the upper edge of the right side wall 25R. In other words, even if the front flap 26F and the rear flap 26B are folded so as to cover the upper opening 23 of the side wall 22, they do not come into contact with each other, do not overlap, and do not close the upper opening 23 of the side wall 22.

[0023] The left flap 26L and the right flap 26R each have a pair of slits 31, and the front flap 26F and the rear flap 26B each have a pair of insertion pieces 32. The left flap 26L and the right flap 26R are folded so as to cover the upper opening 23 of the side wall portion 22 to close the upper opening 23 of the side wall portion 22, and one pair of insertion pieces 32 of the front flap 26F and the rear flap 26B is inserted into one slit 31 of the left flap 26L and one slit 31 of the right flap 26R, and the other pair of insertion pieces 32 of the front flap 26F and the rear flap 26B is inserted into the other slit 31 of the left flap 26L and the other slit 31 of the right flap 26R, so that the four flaps 26F, 26B, 26L, and 26R function as the lid portion 25.

[0024] Although not shown in the figures, the bottom wall portion 21 may have exactly the same configuration as the lid portion 25, or may have a configuration in which, for example, a pair of front and rear flaps are closed, and a pair of left and right flaps are closed to seal the bottom surface 2a of the packaging box 2, and then the flaps are fixed with packaging tape such as duct tape or a stapler.

[0025] The device 3 includes a main body 41 and a power cord 42 extending from the main body 41. The device 3 is a cooking appliance, such as a rice cooker 43, from which the power cord 42 is directly attached. The device 3 is preferably housed in the packaging box 2 with its front, back, and top and bottom aligned.

[0026] The sheet 5 is made of a material that does not allow the plasticizer in the power cord 42 to migrate, such as polyethylene. The sheet 5 is a long object such as a roll of cloth. The sheet 5 may wrap around the device 3 one or more times, or it may not wrap around the device 3 at all, as long as it can prevent direct contact between the device 3 and the cushioning materials 6 and 7.

[0027] The sheet 5 has an excess length 5a that remains even after being wrapped around the device 3. When the start end of the sheet 5 is wrapped around the device 3 and the sheet 5 is wrapped around the device 3, the excess length 5a appears at the end of the sheet 5 at the end of the winding.

[0028] The lower cushioning material 6 and the upper cushioning material 7 hold the equipment 3 housed in the packing box 2 within the packing box 2 and cushion external forces acting on the equipment 3. The lower cushioning material 6 and the upper cushioning material 7 are molded products of expanded polystyrene, expanded polypropylene, or expanded polyethylene, commonly known as Styrofoam.

[0029] The lower cushioning material 6 is sandwiched between the main body 41 around which the sheet 5 is wrapped and the bottom wall 21, and between the main body 41 around which the sheet 5 is wrapped and the side wall 22. At least one lower cushioning material 6 is required. For example, the lower cushioning material 6 may extend across the entire inner bottom surface of the packaging box 2 to support the device 3 from below. The packaging body 1 according to this embodiment includes multiple lower cushioning materials 6. The multiple lower cushioning materials 6 are a pair of lower cushioning materials 6, including a front lower cushioning material 6F arranged on the front side of the bottom of the packaging box 2 and a rear lower cushioning material 6B arranged on the rear side of the bottom of the packaging box 2. The multiple lower cushioning materials 6 may also be a pair of lower cushioning materials 6, including a left lower cushioning material arranged on the left side of the bottom of the packaging box 2 and a right lower cushioning material arranged on the right side of the bottom of the packaging box 2. In other words, the multiple lower cushioning materials 6 are arranged separately on a pair of opposing inner surfaces at the bottom of the packaging box 2.

[0030] The pair of lower cushioning materials 6 contact the main body 41 around which the sheet 5 is wrapped and the four adjacent inner surfaces of the packaging box 2, and do not shift inside the packaging box 2. For example, the front lower cushioning material 6F contacts the main body 41 around which the sheet 5 is wrapped and the inner bottom surface, inner front surface, inner left side surface, and inner right side surface of the packaging box 2.

[0031] The upper cushioning material 7 is sandwiched between the main body 41 around which the sheet 5 is wrapped and the side wall 22, and between the main body 41 around which the sheet 5 is wrapped and the lid 25. At least one upper cushioning material 7 is required. For example, the upper cushioning material 7 may extend over the entire ceiling surface of the packaging box 2, covering the top surface of the device 3. The packaging body 1 according to this embodiment includes multiple upper cushioning materials 7. The multiple upper cushioning materials 7 are a pair of upper cushioning materials 7, consisting of a front upper cushioning material 7F arranged on the front side of the top of the packaging box 2 and a rear upper cushioning material 7B arranged on the rear side of the top of the packaging box 2. The multiple upper cushioning materials 7 may also be a pair of upper cushioning materials 7, consisting of an upper left cushioning material arranged on the left side of the top of the packaging box 2 and an upper right cushioning material arranged on the right side of the top of the packaging box 2. In other words, the multiple upper cushioning materials 7 are arranged separately on a pair of opposing inner surfaces at the top of the packaging box 2.

[0032] The pair of upper cushioning materials 7 contact the main body 41 around which the sheet 5 is wrapped and the four adjacent inner surfaces of the packaging box 2, and do not shift inside the packaging box 2. For example, the front upper cushioning material 7F contacts the main body 41 around which the sheet 5 is wrapped, the ceiling surface, inner front surface, inner left side surface, and inner right side surface of the packaging box 2.

[0033] The rear upper cushioning material 7B has an upper recess 52 that defines an upper storage space 51 between the rear upper cushioning material 7B and the packaging box 2.

[0034] Generally, the power cord 42 is flexible for easy handling. To achieve this flexibility, the power cord 42 has a flexible covering or exterior covering that encases the linear conductors. The flexible covering or exterior covering is made of, for example, vinyl containing a plasticizer.

[0035] If the power cord 42 continues to contact the rear upper cushioning material 7B made of polystyrene foam for a long period of time, the plasticizer contained in the power cord 42 will migrate to the rear upper cushioning material 7B. If the plasticizer migrates to the rear upper cushioning material 7B, the rear upper cushioning material 7B will deteriorate or adhere to the power cord 42. The deteriorated rear upper cushioning material 7B will lose its function as a cushioning material, and the power cord 42 with the rear upper cushioning material 7B attached will reduce the commercial value of the device 3.

[0036] Therefore, in the packaging body 1, at least a portion of the power cord 42 is accommodated in the upper recessed portion 52 of the rear upper cushioning material 7B via the excess length 5a of the sheet 5. The power cord 42 reaches the upper recessed portion 52 by passing between the sheet 5 wrapped around the main body 41 and the packaging box 2. The rear upper cushioning material 7B preferably has a groove that is covered by the excess length 5a of the sheet 5 and guides the power cord 42 into the upper recessed portion 52. A portion of the power cord 42, for example, a free end including a plug that can be connected to a commercial AC power outlet, is placed on the upper recessed portion 52 of the rear upper cushioning material 7B, using the excess length 5a of the sheet 5 like a mat.

[0037] That is, the sheet 5 has an excess length 5a that reaches the upper rear cushioning material 7B. The sheet 5 has the excess length 5a at one end and is wrapped around the main body 41. The excess length 5a covers the entire top surface of the upper rear cushioning material 7B.

[0038] Therefore, the packaging 1 according to this embodiment does not require a cord reel and allows the power cord 42 to be directly pulled out, contributing to the miniaturization of the device 3. It also eliminates the need for a bag to contain the power cord 42, thereby reducing the cost of the bag and the labor costs for packing the power cord 42 into the bag. The power cord 42 of the device 3 does not need to be directly pulled out. Even for a device 3 that has a power cord 42 that can be attached to and detached from the main body 41 with a magnet or a connector, the packaging 1 can store the power cord 42 in the upper recess 52 of the rear upper cushioning material 7B in the same way as a directly pulled out power cord 42, without packing the power cord 42 in a bag separate from the main body 41, using the excess length 5a of the sheet 5 as a mat.

[0039] The upper recess 52 may be provided in the front upper cushioning material 7F. That is, it is sufficient that at least one upper cushioning material 7 has an upper recess 52 that defines the upper storage space 51 between the at least one upper cushioning material 7 and the packaging box 2. The at least one upper cushioning material 7 stores at least a portion of the power cord 42 in the upper recess 52 via the excess length 5a of the sheet 5.

[0040] Furthermore, the lower cushioning material 6, instead of the upper cushioning material 7, may have a lower recess that defines a lower storage space between the lower cushioning material 6 and the packaging box 2. In other words, at least one lower cushioning material 6 may have a lower recess that defines a lower storage space between the at least one lower cushioning material 6 and the packaging box 2. In this case, the at least one lower cushioning material 6 accommodates at least a portion of the power cord 42 in the lower recess via the excess length 5a of the sheet 5.

[0041] The sheet 5 only needs to have an excess portion 5a that reaches at least one upper cushioning material 7 having an upper recess 52 or at least one lower cushioning material 6 having a lower recess. Therefore, it is preferable that the excess portion 5a cover the entire upper surface 2b of at least one upper cushioning material 7 having an upper recess 52, or the entire lower surface of at least one lower cushioning material 6 having a lower recess. This prevents the power cord 42 that reaches the upper recess 52 or the lower recess from touching a part of the upper cushioning material 7 that is not the upper recess 52 or a part of the lower cushioning material 6 that is not the lower recess.

[0042] The power cord 42 may pass between the sheet 5 wound around the main body 41 and the packaging box 2 and reach the upper recess 52 or the lower recess.

[0043] In other words, the packaging body 1 is not limited to accommodating the power cord 42 in the upper rear cushioning material 7B, and can flexibly accommodate the relationship between the device body 41 and the attachment position of the power cord 42. For example, if the total length of the power cord 42 is short and it does not reach the upper rear cushioning material 7B, the power cord 42 can be accommodated in the lower recess of the lower cushioning material 6 via the excess length portion 5a of the sheet 5.

[0044] At least one upper cushioning material 7 may have a second upper recess 56 that defines the second upper storage space 55. The rear upper cushioning material 7B has a second upper recess 56 that defines the second upper storage space 55. The second upper recess 56 accommodates accessories of the appliance 3, for example, a rice scoop 59 used in the rice cooker 43. There may be multiple second upper recesses 56 so that a measuring cup can be accommodated in addition to the rice scoop 59.

[0045] Next, a method for packaging the device 3 in the package 1 will be described.

[0046] The packaging method according to this embodiment involves preparing a packaging box 2, placing a lower cushioning material 6 on the bottom of the packaging box 2, laying a sheet 5 on top of the lower cushioning material 6, placing a device 3 having a main body 41 and a power cord 42 extending from the main body 41 on the sheet 5 so that the lower cushioning material 6 is sandwiched between the main body 41 and the bottom wall 21 and between the main body 41 and the side wall 22, and storing the device 3 in the packaging box 2, wrapping the sheet 5 around the device 3, placing an upper cushioning material 7 over the main body 41 around which the sheet 5 is wrapped while avoiding the excess portion 5a of the sheet 5, placing the excess portion 5a of the sheet 5 over an upper recess 52 that defines an upper storage space 51 between the upper cushioning material 7 and the packaging box 2, storing at least a portion of the power cord 42 in the upper recess 52, and closing the lid 25.

[0047] In the process of winding the sheet 5 around the device 3, the end of the sheet 5 at the beginning of winding is wrapped around the device 3, and the sheet 5 is simply wound around the device 3 by wrapping the sheet 5 around the device 3, and the end of the sheet 5 at the end of winding is left loose, so that the excess length 5a can be easily formed.

[0048] When the upper cushioning material 7 is placed over the equipment 3, it is preferable that the excess length 5a of the sheet 5 is passed between the upper cushioning material 7 and the inner surface of the packaging box 2, and hangs down from the upper opening 23 of the packaging box 2 to the outside of the packaging box 2. It is also preferable that the power cord 42 is passed between the excess length 5a of the sheet 5 and the inner surface of the packaging box 2, and hangs down from the upper opening 23 of the packaging box 2 to the outside of the packaging box 2. Doing so significantly reduces the effort required for the packaging work.

[0049] Furthermore, when a manual 58 for the device 3 is packed in the package 1, it can be placed between the upper cushioning material 7 and the lid 25 of the packaging box 2. The manual 58 can be placed so as to cover the upper cushioning material 7, and then the lid 25 can be closed. The manual 58 may be placed on the lower cushioning material 6 on the inner bottom surface of the packaging box 2, or the manual 58 may be sandwiched in the gap between the inner surface of the packaging box 2 and the lower cushioning material 6.

[0050] Furthermore, when the power cord 42 is stored in the lower recess of the lower cushioning material 6, the power cord 42 can be placed in the lower recess when the sheet 5 and the device 3 are stored together in the packaging box 2 so that the lower cushioning material 6 is sandwiched between the main body 41 around which the sheet 5 is wrapped and the bottom wall portion 21, and between the main body 41 around which the sheet 5 is wrapped and the side wall portion 22.

[0051] The packaging 1 according to this embodiment, configured as described above, includes at least one upper cushioning material 7 that accommodates at least a portion of the power cord 42 in the upper recess 52 via the excess length 5a of the sheet 5, or at least one lower cushioning material 6 that accommodates at least a portion of the power cord 42 in the lower recess 52 via the excess length 5a of the sheet 5. Therefore, the packaging 1 can easily prevent plasticizers contained in the coating or exterior of the power cord 42 from migrating to the polystyrene foam cushioning materials 6, 7. The sheet 5 has traditionally been used to protect the device 3. Even with the excess length 5a applied to the sheet 5, the packaging 1 can reduce costs and labor costs by using a bag to prevent direct contact between the power cord 42 and the cushioning materials 6, 7, or by providing a cord reel to the device 3 to accommodate the power cord 42.

[0052] Furthermore, packaging body 1 according to this embodiment accommodates device 3 having power cord 42 that passes between sheet 5 wrapped around main body 41 and packaging box 2 and reaches upper recess 52 or lower recess 52. Therefore, packaging body 1 has a structure that allows power cord 42 to be easily placed inside packaging box 2 so as to prevent plasticizer contained in the coating or exterior of power cord 42 from migrating into polystyrene foam cushioning materials 6, 7, and can provide an easy packaging procedure for the person packing device 3.

[0053] Furthermore, the packaging body 1 according to this embodiment includes a sheet 5 that has an excess length 5a at one end and is wrapped around the main body 41. Therefore, the packaging body 1 has a structure that allows the sheet 5 to be easily wrapped around the device 3 so as to prevent the plasticizer contained in the coating and exterior of the power cord 42 from migrating to the polystyrene foam cushioning materials 6, 7, and can provide an easy packaging procedure for the person packing the device 3. By making one end of the sheet 5 the end at which the wrapping ends, the sheet 5 can be wrapped around the device 3 simply by wrapping the beginning end of the wrapping of the sheet 5 around the device 3 and wrapping the sheet 5 around the device 3, and the excess length 5a can be easily formed by leaving the end at which the wrapping ends of the sheet 5 are loose.

[0054] Furthermore, the packaging body 1 according to this embodiment includes a sheet 5 having an excess portion 5a that covers the entire upper surface of at least one upper cushioning material 7 and the entire lower surface of at least one lower cushioning material 6. Therefore, in the packaging body 1, the power cord 42 that reaches the upper recess 52 or the lower recess will not come into contact with a portion of the upper cushioning material 7 that is not the upper recess 52 or a portion of the lower cushioning material 6 that is not the lower recess, and it is possible to more reliably prevent the plasticizer contained in the coating or exterior of the power cord 42 from migrating to the polystyrene foam cushioning materials 6, 7.

[0055] Furthermore, the packaging body 1 according to this embodiment is provided with a pair of lower cushioning materials 6 that are spaced apart and disposed on a pair of opposing inner surfaces at the bottom of the packaging box 2. Therefore, the packaging body 1 can reduce the chance of contact between the power cord 42 and the cushioning materials 6, 7 compared to, for example, a case in which the packaging box 2 is provided with cushioning materials that extend over the entire bottom.

[0056] Furthermore, the packaging body 1 according to this embodiment packages a rice cooker 43 with a power cord 42 directly attached as the device 3. Therefore, the packaging body 1 does not include a cord reel for the power cord 42, which contributes to making the rice cooker 43 smaller.

[0057] In addition, the packaging method according to this embodiment includes preparing a packaging box 2, wrapping a sheet 5 around a device 3 having a main body 41 and a power cord 42 extending from the main body 41, placing at least one lower cushioning material 6 on the bottom of the packaging box 2, sandwiching the at least one lower cushioning material 6 between the main body 41 around which the sheet 5 is wrapped and the bottom wall portion 21, and between the main body 41 and the side wall portion 22, covering the main body 41 around which the sheet 5 is wrapped with at least one upper cushioning material 7 while avoiding the excess portion 5a of the sheet 5, covering an upper recess 52 that defines an upper storage space 51 between the at least one upper cushioning material 7 and the packaging box 2 with the excess portion 5a, storing at least a portion of the power cord 42 in the upper recess 52, and closing the lid portion 25. Therefore, while the packaging method follows the conventional packaging method, it eliminates the process of individually bagging power cord 42, thereby simplifying the packaging work and reducing labor costs, while easily preventing the plasticizer contained in the coating and exterior of power cord 42 from migrating into the polystyrene foam cushioning materials 6 and 7.

[0058] Therefore, the packaging body 1 and packaging method according to the present invention can prevent contact between the power cord 42 of the device 3 and the buffer materials 6, 7 easily and inexpensively.

[0059] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
