In the bearing groove 31 , an upper pressing portion 5 may be further provided for pressing the movement of the shaft support portion 11 supported by the bearing groove 31 . The components of the packaging container 1 according to the embodiment of the present invention can be formed from materials such as wood and plastic, and are more preferably made of corrugated paper.

As the storage object 10 accommodated in the packaging container 1, if it is a roll formed by winding various materials such as metal, plastic, paper, synthetic resin, etc., various films, sheets, foils, strips, etc. around the axis 12, There is no particular limitation. In particular, in this embodiment, although the case where the copper foil roll which wound copper foil or copper alloy foil around the axis|shaft 12 was used as the accommodation object 10 was demonstrated, it is not limited to this.

As shown in FIG. 2 , the storage object 10 includes shaft support portions 11 that respectively protrude from both ends of the shaft center 12 in the axial direction. By supporting the shaft support 11 of the storage object 10 by the bearing groove 31 of the main frame 3 , the storage object 10 can be stored in the main frame 3 in a suspended state. Thereby, the influence of the external force and the gravitational force applied to the roll portion of the storage object 10 can be reduced, and the deformation of the storage object 10 can be suppressed.

As shown in FIG. 3 , the pallet 2 includes: a bottom surface 22: on which the main body frame 3 is placed, a pair of end wall portions 23: erected from the bottom surface 22 and facing each other, and a pair of side wall portions 24: continuous with the end wall portion 23, from The bottom surfaces 22 are erected, facing each other, and the feet 21 : connected to the bottom surface 22 .

By arranging the end wall portion 23 and the side wall portion 24 on the pallet 2 , the main body frame 3 stacked on the pallet 2 can be accommodated in a predetermined position, and the positional displacement of the main body frame 3 can be suppressed.

As shown in FIG. 4 , the leg portion 21 is provided with: a laminated body portion 21a: formed by laminating a plurality of corrugated cardboard sheets, and the corrugated cardboard is formed by laminating a corrugated center core between pads and pads , and the sheet-like foot reinforcement portion 21b: attached to the laminated body portion 21a.

Typically, the laminated body 21a has a structure in which about 5 to 20 corrugated cardboard sheets having a thickness of about 5 to 10 mm are laminated in a direction horizontal to the bottom surface 22 (direction perpendicular to the vertical direction) through an adhesive layer. The leg part reinforcement part 21b is attached so that the end surface of the laminated body part 21a may be covered, and the bottom surface of the leg part 21 is reinforced.

By arranging the leg reinforcement portion 21b on the laminated body portion 21a, the hardness of the bottom surface of the leg portion 21 can be increased, and the failure during transportation caused by the deformation of the leg portion 21 such as breakage and depression during transportation can be prevented. Furthermore, the stackable weight of the pallet 2 and the strength of the legs 21 can be adjusted by adjusting the material of the liner and the core of the corrugated cardboard constituting the laminated body 21a, or the number of layers of the corrugated cardboard.

As shown in FIG. 5 , on the inner side (center side) of the pallet 2 with respect to the end wall portion 23 , the leg portion 21 is arranged at a fixed interval S from the end wall portion 23 . The space S functions as a holding surface 26 for suspending and holding the hoisting tool on both ends of the packaging container 1 . According to the packaging container 1 of the present embodiment, the packaging container 1 can be hoisted and transported stably by contacting a lifting member such as a rope against the holding surface 26, so that the packaging container 1 can be transported more smoothly.

Furthermore, if a conveyance method in which the packaging container 1 is lifted and conveyed can be adopted, the packaging container 1 packed with heavy goods can be conveyed by a crane or the like even in a facility with a structure that cannot be accessed by a stacker or the like. By adding the option of the conveyance means in this way, the restriction on the facility where the contents of the packaging container 1, that is, the storage object 10, can be eased. In addition, the safety of the work site can be improved.

Preferably, between the legs 21 of the bottom surface 22 of the pallet 2 , a bottom reinforcement portion 25 capable of reinforcing the bottom surface 22 of the pallet 2 is arranged. Thereby, the bottom surface 22 of the pallet 2 can be reinforced, the deformation|transformation of the packaging container 1 can be suppressed, and the intensity|strength can be improved. In addition, when the packaging container 1 is bound with the binding member 71 such as the following tape, the binding of the binding member 71 will When the force is so strong that it sinks into the bottom reinforcement portion 25, the deformation of the pallet 2 itself can also be suppressed. The binding strength can also be improved by binding the binding member 71 so as to be in contact with the bottom surface reinforcement portion 25 and to be entrapped in the bottom surface reinforcement portion 25 .

As described above, when a hoisting member such as a rope is brought into contact with the holding surface 26 to hoist the packaging container 1, a load is applied to the vicinity of the center of the packaging container 1, and the packaging container 1 may deform as a result. In view of such a problem, when the packaging container 1 is hoisted and transported, the packaging container 1 can be suppressed from being bent in the vicinity of the center by providing the bottom reinforcement portion 25 . When the packaging container 1 is transported using a stacker or the like, even when the claws of the stacker are operated by mistake, damage to the bottom surface 22 of the pallet 2 can be suppressed.

The arrangement position, shape, and thickness of the bottom surface reinforcement portion 25 are not particularly limited, and various selections can be made according to the application. The bottom surface reinforcement portion 25 is further arranged on the holding surface 26, thereby further suppressing damage to the packaging container 1 during transportation.

The pallet 2 is provided on the side wall portion 24 with four bending lines RL respectively extending obliquely upward from the four corners C of the rectangular bottom surface 22 of the pallet 2 . The bending line RL is inclined at a slope of about 45 degrees from the point (corner C) where the bottom surface 22 , the end wall portion 23 , and the side wall portion 24 meet with respect to the line L1 where the bottom surface 22 and the side wall portion 24 meet. By bending the folding line RL into a mountain fold line, the pallets 2 can be stored in layers with the end wall portion 23 and the side wall portion 24 folded, so that the storage space before being assembled into the packaging container 1 can be reduced. In the case of using the packaging container 1, only the end wall portion 23 and the side wall portion 24 of the pallet 2 can be erected, so the assembly of the pallet 2 is also easy.

As shown in FIG. 1 , the main frame 3 includes a main frame body 30 and at least one auxiliary frame 34 and 35 laminated on the main frame main body 30 . By forming the main body frame 3 with a plurality of members in this way, the strength of the main body frame body 30 represented by the bearing groove 31 provided in the main body frame 3 can be improved. The auxiliary frames 34 and 35 may also be omitted.

The main frame body 30 has a pair of end wall portions 32 facing each other and a pair of side wall portions 33 facing each other, and has a side wall portion 33 between the end wall portions 32 facing each other. The main frame body 30 has a first bearing groove 310 on the end wall portion 32 for supporting the shaft support portion 11 of the storage object 10 , respectively.

The main frame body 30 is formed by connecting two main frame main body members 37 as shown in FIG. 7( a ), and as shown in FIG. 33) shape. The main frame body member 37 includes an end wall portion 32 , a side wall portion 33 connected to the end wall portion 32 , and a joint margin 36 formed at the end of the end wall portion 32 . The main frame body 30 can be obtained by connecting the joint margin 36 of one main frame main body member 37 to the end of the side wall portion 33 of the other main main frame main body member 37 .

The first bearing groove 310 includes an accommodation portion 311 capable of accommodating the shaft support portion 11 at the lower end portion, and includes an accommodation portion 313 capable of accommodating the upper pressing portion 5 at the upper end portion. The side surface of the first bearing groove 310 is provided with a locking portion 312 protruding toward the inner center of the first bearing groove 310 in order to abut and support the lower end portion 54 (see FIG. 10 ) of the upper pressing portion 5 . Since the bottom of the lower end portion 54 of the upper pressing portion 5 and the upper surface of the locking portion 312 are in contact with each other, the upper pressing portion 5 can be prevented from being displaced and falling toward the lower side of the first bearing groove 310 .

In the first bearing groove 310 , the width W1 in the horizontal direction of the arc of the lower end portion of the first bearing groove 310 has a dimension equal to the diameter of the shaft support portion 11 of the storage object 10 . Thereby, the shaft support part 11 protruding from the both ends of the storage object 10 can be accommodated in the lower end part of the first bearing groove 310 . The horizontal width W2 of the upper end portion of the first bearing groove 310 is larger than the width W1 of the lower end portion of the first bearing groove 310 . Thereby, the end wall portion 32 of the main frame body 30 can be prevented from being damaged, and at the same time, the shaft support portion 11 of the accommodation object 10 can be easily accommodated in the first bearing groove 310 .

In the first bearing groove 310 of the main frame body 30 , one or more reinforcing pads 38 as shown in FIG. 7( b ) can also be attached to the end wall 32 of the main frame body member 37 . Thereby, the load resistance of the 1st bearing groove 310 can be improved.

The reinforcing pad 38 includes a bearing groove 318 including receiving portions 3118 , 3138 and a locking portion 3128 having substantially the same shape as the receiving portions 311 , 313 and the locking portion 312 , respectively. Since the bearing groove 318 and the first bearing groove 310 have substantially the same shape, it is possible to prevent rattling when the shaft support portion 11 is placed. On the other hand, since the main frame body 30 and the reinforcing pads 38 are made of corrugated paper, the first bearing may also be generated due to the weight of the storage object 10 exerting a load on the bearing groove 318 and the first bearing groove 310 via the shaft support 11 . groove 310 and the deformation of the bearing groove 318, so there are cases where a certain dimensional margin needs to be provided. Therefore, the shapes of the first bearing groove 310 of the main frame body 30 and the bearing groove 318 of the reinforcing pad 38 may not necessarily have the same shape. Furthermore, the number of layers of the reinforcing pad 38 to the end wall 32 can be appropriately adjusted in consideration of the weight of the storage object 10 to be stored and the length of the shaft support 11 of the storage object 10 .

On the main frame body 30, at least one auxiliary frame 34, 35 is laminated. As shown in FIG. 8( a ), the auxiliary frame 34 includes an auxiliary side wall portion 334 , and a first auxiliary end wall portion 324 a and a second auxiliary end wall portion 324 b arranged at both ends of the auxiliary side wall portion 334 . The first auxiliary end wall portion 324a has a second bearing groove 314a including receiving portions 3114 and 3134 and a locking portion 3124 having substantially the same shape as the first bearing groove 310 . The second auxiliary end wall portion 324b includes a conveyance arm insertion groove 314b, and the width W3 of the lower end of the conveyance arm insertion groove 314b in the horizontal direction of the arc is smaller than the width W1 of the lower end of the first bearing groove 310 in the horizontal direction of the arc.

The auxiliary frame 35 may have the same configuration as the auxiliary frame 34 . That is, the auxiliary frame 35 includes the auxiliary side wall portion 335 , and the first auxiliary end wall portion 325 a and the second auxiliary end wall portion 325 b arranged at both ends of the auxiliary side wall portion 335 . The first auxiliary end wall portion 325a includes a second bearing groove 315a having receiving portions 3115 and 3135 and a locking portion 3125 having substantially the same shape as the first bearing groove 310 . The second auxiliary end wall portion 325b includes a conveyance arm insertion groove 315b whose width W3 in the horizontal direction of the arc at the lower end of the conveyance arm insertion groove 315b is smaller than the width W1 in the horizontal direction of the arc at the lower end of the first bearing groove 310 .

The width W3 is smaller than the width W1, which means when the main frame body 30, the auxiliary frame 34, and the auxiliary frame 35 are stacked, and the shaft support portion 11 is placed on the end wall portion 32 and the first auxiliary end wall portion 325a provided with the first bearing In the groove 310 and/or the second bearing groove 315a, the outer side of the shaft support portion 11 is in contact with the second auxiliary end wall portion 324b, and the second auxiliary end wall portion 324b covers a part of the shaft center 12 of the shaft support portion 11 (refer to FIG. 8 ). (b)). Thereby, the second auxiliary end wall portion 324b can restrict the axial movement of the storage object 10 accommodated in the packaging container 1 . As a result, it is possible to reduce the possibility that the shaft support portion 11 falls off from the bearing groove 31 and the storage object 10 falls and is damaged during transportation of the packaging container 1 .

If the width W3 of the carrying arm insertion groove 314b can limit the axial movement of the storage object 10 It does not matter if the degree of movement is smaller than the width W1. Among them, the shaft center 12 of the shaft support portion 11 has a hollow structure, and there are preferred aspects as described later in the aspect in which the conveying arm of the conveying tool for accommodating the object 10 is inserted into the inner side of the shaft center 12 and conveyed. For example, if the width W3 is a width that allows insertion of a conveying arm, when the storage object 10 is wound around a roll having a hollow shaft 12, it is placed on a packaging container 1, a conveyance tool can be used, and the storage object 10 can be efficiently conveyed by a machine.

The first auxiliary end wall portion 324a of the auxiliary frame 34 may also be provided with a reinforcing pad 39a having a conveying arm groove 391 having substantially the same width W3 as the second auxiliary end wall portion 324b at the lower end. The second auxiliary end wall portion 324b of the auxiliary frame 34 may also be provided with a reinforcing pad 39b having a conveying arm groove 392, the conveying arm groove 392 having substantially the same width W3 as the second auxiliary end wall portion 324b at the lower end. Like the auxiliary frame 34, the auxiliary frame 35 may also be provided with reinforcing pads 39a and 39b. Thereby, the rigidity of the packaging container 1 as a whole can be improved, and the strength when the packaging container 1 is transported in the air can be ensured. The reinforcing pads 39a and 39b may be omitted as necessary.

When assembling the main body frame 3, the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a and the first auxiliary end wall portion 325a of the main body frame 2. The auxiliary end wall portion 324b is laminated on the main frame body 30.

9 is a plan view showing a method of overlapping the main frame body 30 and the auxiliary frames 34 and 35 when the reinforcing pads 39 a and 39 b are attached to the auxiliary frames 34 and 35 . The auxiliary frames 34 and 35 are overlapped on the outer surface of the main frame body 30 with the main frame body 30 in the middle and facing each other.

As shown on the right side of the drawing in FIG. 9 , on the outer surface of one end wall 32 of the main frame body 30, a first auxiliary end wall 325a of the auxiliary frame 35 provided with the second bearing groove 315a is laminated. A reinforcing pad 39a is attached to the outer surface of the first auxiliary end wall portion 325a, and the second auxiliary end wall portion 324b of the auxiliary frame 34 having the conveyance arm insertion groove 314b is laminated on the outer surface. A reinforcing pad 39b is attached to the outer surface of the second auxiliary end wall portion 324b.

9, on the outer surface of the other end wall 32 of the main frame body 30, the first auxiliary end wall 324a of the auxiliary frame 34 having the second bearing groove 314a is laminated. A reinforcing pad 39a is attached to the outer surface of the first auxiliary end wall portion 324a, and the second auxiliary end wall portion 325b of the auxiliary frame 35 having the conveyance arm insertion groove 315b is laminated on the outer surface. A reinforcing pad 39b is attached to the outer surface of the second auxiliary end wall portion 325b.

By having such a layered structure, the shaft support portion 11 on the right side of the drawing in FIG. 9 is supported by the end wall portion 32 and the first auxiliary end wall portion 325a, and is a reinforcing pad attached to the outer surface of the first auxiliary end wall portion 325a. The inner surface of 39a is substantially in contact with the end surface of the shaft support portion 11 of the storage object 10, and the movement of the shaft support portion 11 in a direction parallel to the axial direction is suppressed. As a result, it is possible to provide a structure suitable for air transportation while suppressing breakage and deformation of the packaging container 1 .

The material constituting the main frame body 30, the auxiliary frames 34, 35, and the reinforcing pads 38, 39a, 39b may be the same type, but when components with different strengths are used, the first bearing groove 310 is supported and accommodated at the innermost side. The pivot portion 11 of the object 10 is preferably formed of a material with higher strength than the auxiliary frames 34 and 35 (more specifically, a material with higher compressive strength) for the main frame body 30 .

The materials of the auxiliary frames 34 , 35 and the reinforcing pads 38 , 39 a , 39 b are preferably the same as those of the main frame body 30 . On the other hand, the material cost may be very high due to the use of materials with higher compressive strength. Therefore, according to the required strength of the packaging container 1 , whether to make the auxiliary frames 34 , 35 and the reinforcing pads 38 , 39 a , 39 b the same materials as the main frame body 30 is appropriately selected.

The bearing groove 31 of the main body frame 3 supporting the shaft support 11 of the storage object 10 is affected by the weight of the storage object 10 and the external force during transportation, and is prone to deformation or damage such as crushing. Therefore, it is preferable to arrange the bearing groove 31 of the main frame 3 in the vertical direction of the leg portion 21 .

When the main frame 3 has a three-layer structure of the main frame body 30 and the auxiliary frames 34 and 35, the first bearing groove 310 and the second bearing grooves 314a and 315a which constitute the bearing groove 31 support the storage object at the innermost side. The first bearing groove 310 of the main frame body 30 of the shaft support portion 11 of the object 10 has a receiving object 10 the weight and the influence of external forces during transportation. Therefore, it is preferable to arrange at least the leg portion 21 of the pallet 2 on the vertical line (in the vertical direction) of the contact point between the first bearing groove 310 of the main frame body 30 and the innermost point of the shaft support portion 11 of the storage object 10 . In this way, the packaging container 1 is constituted.

As an example of such a configuration, adjusting the number of pieces of the main frame body 30 , the auxiliary frames 34 , 35 , and the reinforcing pads 38 , 39 a , 39 b can be used to adjust the contact point of the innermost part of the shaft support 11 and the first bearing groove 310 . Relative to the position of the foot 21 . In this way, the weight of the storage object 10 transmitted from the shaft support 11 supported by the bearing groove 31 of the main frame 3 can be supported by the legs 21 , so even if it is transported for a long time, the weight of the storage object 10 is less likely to occur. Deformation and damage of the packaging container 1 .

In addition, by arranging the auxiliary frames 34 and 35 arranged so as to surround the main frame body 30 directly above the holding surface 26 for hanging and holding the hoisting tool on both ends of the packaging container 1, the The load resistance is improved, and the weight of the storage object 10 can be easily supported, so that a stable transport state can be realized.

During storage, the main frame body 30 and the auxiliary frames 34 and 35 having two sets of opposite wall portions (the end wall portion 32 and the side wall portion 33 ) can be bent and folded, so the area during storage can be saved. When in use, the main frame body 30 and the auxiliary frames 34 and 35 can be assembled and used, so there is no need for a large storage space as in the conventional wooden container, so that the packaging container 1 can be stored more efficiently.

As shown in FIG. 10 , the upper pressing portion 5 includes a base pad 51 and a guide pad 52 laminated in the vicinity of the center portion of the base pad 51 . A curved portion 53 is formed below the guide pad 52, and the curved portion 53 is substantially the same shape as the curved surface of the outer peripheral surface of the shaft support portion 11 of the storage object 10, and restricts the vertical movement of the storage object 10 during conveyance. The lower end 54 of the upper pressing part 5 contacts and stops on the locking part 312 of the main frame body 30, so it is not easy to produce positional deviation caused by vibration during transportation, etc., so that the upper pressing part 5 can be stably stored in the long-term storage. Inside the storage portion 313 .

The guide pad 52 on the base pad 51 has a structure formed by laminating a plurality of corrugated cardboards through an adhesive. The stacked height of the guide pad 52 is preferably adjusted to match the thickness of the stacked portion stacked on the end wall 32 of the main frame body 30 . By arranging the upper pressing portion 5 in the bearing groove 31 of the main frame 3, it is possible to limit the It controls the movement of the storage object 10 in the main body frame 3 during transportation.
