JP 2012-106747 A

However, in the above conventional packaging box, when the roll-shaped object is taken out in the building, a sufficiently high space (space) is required in the building to lift the roll-shaped object upward. . In addition, some roll-like objects are very heavy (for example, 100 kg or more), and in that case, a dedicated facility for lifting the roll-like object is required. That is, in order to lift and take out the roll-shaped object upward, there is a problem that the structure and facilities of the building are restricted.
Moreover, in the said conventional packaging box, in order to take out a roll-shaped thing from a packaging box, without lifting up, there exists a problem that the side wall part of a box main body must be cut off and a packaging box cannot be reused.

  The present invention has been made in view of the above-described circumstances, and can be easily taken out of a roll-like product without being restricted by the structure or equipment of the building, and can be reused. The purpose is to provide a packaging box.

  The packaging box for a roll-shaped object of the present invention is a packaging box for a roll-shaped object capable of accommodating a roll-shaped object formed by winding a sheet around a winding core in a suspended state, and has a rectangular cylindrical shape having four side walls. A box main body in which an accommodation space for accommodating the roll-shaped object is formed by including an upper lid that closes an opening above the trunk frame, and a lower lid that closes an opening below the trunk frame; The core is formed in a plate shape so as to be overlapped on the inner surface side of a pair of first side wall portions facing each other out of the body frame, and the roll core is accommodated inside the body frame. A pair of bearing plate portions that support a pair of projecting portions that project from both ends in the axial direction of the sheet wound in a roll shape from below, and one first side wall portion of the body frame is, An opening between a pair of second side wall portions of the trunk frame adjacent to the opening can be freely opened and closed. In so that, characterized in that it is rotatably connected to at least one of the pair of second side wall portion.

With respect to the packaging box of the present invention, the roll-shaped object is accommodated so that the axial direction thereof faces the arrangement direction of the pair of first side wall portions.
When taking out the roll-shaped object accommodated in this packing box, the packing box is arranged in advance so that the axial direction of the roll-shaped object is in the horizontal direction. And what is necessary is just to rotate one 1st side wall part from the position (closed position) which closes the opening between a pair of 2nd side wall parts to the position (open position) which opens. In this state, the axial end portion of the roll-like object disposed in the housing space of the box body is exposed to the outside of the box body from the opening between the pair of second side wall portions. For this reason, by moving the roll-shaped object in the axial direction of the roll-shaped object relative to the box body, that is, by moving the roll-shaped object in the horizontal direction, the roll-shaped object can be taken out of the box body. it can.

  Therefore, according to the packaging box of the present invention, it is not necessary to lift the roll-shaped object upward as in the conventional case. It is only necessary to have a space that can be accommodated (particularly the height of the space). Moreover, the equipment which lifts a roll-shaped object becomes unnecessary. In other words, it is possible to easily take out the roll-like object without being restricted by the structure or equipment of the building.

Moreover, according to the packaging box of this invention, since a roll-shaped thing can be taken out without cutting off the side wall part of a box main body, it also becomes possible to reuse the packaging box after taking out a roll-shaped thing.
Furthermore, in the packing box of the present invention, the roll-shaped object is accommodated outside by accommodating the roll-shaped object in the accommodating space of the box body so that both protrusions of the core are supported by the pair of bearing plate parts. The roll can be stored and transported without being exposed.

  In the packaging box for rolls, a plurality of the trunk frames are arranged in the arrangement direction of the pair of second side wall portions of the trunk frame, and a plurality of the trunk frames are arranged next to each other. The second side wall portions of the matching body frame may be in surface contact with each other.

  According to the said structure, since the 2nd side wall parts of mutually adjacent trunk frames overlap, the rigidity of a 2nd side wall part can be improved. For example, even if the body frame is made of a material that is bent and deformed by receiving a large external force such as cardboard, the body frame is held in a square tube shape by suppressing the bending deformation of the second side wall portion. Can do.

  Further, in the roll box packaging box, the trunk frame is foldable, the lower lid is detachable from the trunk frame, and closes an opening below the trunk frame. You may provide the shape holding | maintenance part which hold | maintains a trunk frame in a square cylinder shape.

  According to the said structure, after taking out a roll-shaped thing from a packing box, a trunk frame can be folded by removing a lower cover from a trunk frame. Therefore, the packaging box can be stored and transported in a compact manner.

  Furthermore, in the packaging box for the roll-shaped object, the shape holding portion protrudes from the bottom surface of the lower lid that contacts the lower opening end of the trunk frame and extends along the second side wall portion on the bottom surface. A pair of protrusions formed extending and spaced from each other in the arrangement direction of the pair of second side wall parts, and the pair of protrusions has an opening end below the trunk frame, You may contact the inner surface of said pair of 2nd side wall part in the state contact | abutted to the bottom face, respectively.

According to the said structure, a trunk frame can be hold | maintained in a square cylinder shape by the lower end part of a trunk frame being hold | maintained from a inner surface side of a trunk frame by a pair of protrusion part.
In addition, since the pair of protrusions are arranged with an interval in the arrangement direction of the pair of second side wall portions, when moving the roll-shaped object in the axial direction of the roll-shaped object with respect to the box body, The pair of protrusions are not caught on the roll-shaped object. That is, it becomes possible to take out the roll-like material more easily.

  In the packing box for rolls, the bearing plate portion may be detachable from the box body.

  According to the above configuration, a roll-like object arranged in the same body frame by simply selecting a plurality of types of bearing plate portions having different shapes and numbers of notches and attaching them to other portions of the box body. It is possible to easily change the size (for example, the diameter dimension of the roll-shaped material, the diameter dimension of the core) and the number of the rolls. That is, since the same thing can be used for the other part of the box body excluding the bearing plate part regardless of the size and number of the roll-like objects, the versatility of the packaging box can be improved.

According to the present invention, a roll-like object can be easily taken out from a packing box without being restricted by a building structure or equipment.
Moreover, according to this invention, it becomes possible to reuse the packaging box after taking out a roll-shaped thing.

The lower lid 12 includes a bottom wall portion 21 that closes an opening below the trunk frame 11, a shape holding portion 22 that holds the trunk frame 11 in a rectangular tube shape with the opening below the trunk frame 11 closed, Is provided.
The shape holding part 22 of the present embodiment includes a pair of protrusions 23 fixed to the bottom surface 21 a of the bottom wall part 21 that abuts the lower opening end of the trunk frame 11. Each ridge 23 protrudes from the bottom surface 21a of the bottom wall portion 21 and extends along the second side wall portion 15 on the bottom surface 21a. The length of each protrusion 23 is set to be equal to the width of the inner surface of the second side wall 15, that is, the distance between the pair of first side walls 14. Moreover, the height dimension of each protrusion part 23 is set sufficiently smaller than the dimension of the axial direction of the trunk frame 11. Each protrusion 23 in the illustrated example is formed in a rectangular column shape or a rectangular tube shape, but may be formed in an arbitrary column shape such as a columnar shape or a cylindrical shape or a cylindrical shape.

The pair of protrusions 23 are arranged at intervals in the arrangement direction of the pair of second side wall portions 15. Here, the dimension of the pair of protrusions 23 in the arrangement direction of the second side wall 15 is set to be equal to the interval between the pair of second side walls 15.
As a result, the pair of protrusions 23 come into contact with the inner surfaces of the pair of second side wall portions 15 in a state where the opening ends below the trunk frame 11 are in contact with the bottom surface 21 a of the bottom wall portion 21. In this state, both ends of the pair of protrusions 23 in the longitudinal direction are in contact with the inner surfaces of the pair of first side wall portions 14. That is, the pair of ridges 23 contacts all the insides of the four corners of the trunk frame 11.

In the present embodiment, a plurality of (two in the illustrated example) shape holding portions 22 are arranged in the arrangement direction of the second side wall portion 15 on the bottom surface 21 a of the bottom wall portion 21. And the two shape holding | maintenance parts 22 adjacent to each other are distribute | arranged at intervals in the sequence direction of the 2nd side wall part 15. As shown in FIG. This interval is set to, for example, twice the thickness dimension of the second side wall portion 15.

That is, the lower openings of the plurality of trunk frames 11 are collectively closed by the same lower lid 12. Further, in a state where the plurality of trunk frames 11 are arranged on the bottom surface 21 a of the lower lid 12, the second side wall portions 15 of the trunk frames 11 adjacent to each other are sandwiched between the two shape holding portions 22, so that The second side wall portions 15 are in surface contact with each other.

The upper lid 13 closes the opening above the trunk frame 11 having a square cylindrical shape. The upper lid 13 of the present embodiment includes a plate-like ceiling plate portion 31 formed in a rectangular shape in plan view corresponding to the shape in plan view of the trunk frame 11, and a top surface 31 b of the ceiling plate portion 31 facing downward on the trunk frame 11. And an annular locking portion 32 having a rectangular shape in plan view, which is provided upright at the periphery.
The ceiling plate part 31 closes the opening above the trunk frame 11 by contacting the opening end above the trunk frame 11. Since the box main body 2 of the present embodiment includes a plurality of trunk frames 11, the ceiling plate portion 31 is formed in a rectangular shape in plan view corresponding to the planar view shape of the plurality of trunk frames 11 arranged as described above.

When the ceiling plate portion 31 is brought into contact with the upper opening end of the trunk frame 11, the upper end portion of the trunk frame 11 is inserted into the annular locking portion 32. In this state, since the annular locking portion 32 is locked to the upper end portion of the trunk frame 11, the direction of the upper lid 13 along the top surface 31 b of the ceiling plate portion 31 with respect to the trunk frame 11 (direction along the XY plane). The upper lid 13 does not come off the body frame 11 even if it is moved to.
Further, the size and shape of the annular locking portion 32 are set so that the inner surface of the annular locking portion 32 is in surface contact with the outer surface of the trunk frame 11 with the upper end portion of the trunk frame 11 being inserted into the annular locking portion 32. Then, it is possible to prevent the upper lid 13 from moving in the direction along the XY plane with respect to the trunk frame 11.

Furthermore, in a state where the upper end portion of the trunk frame 11 is inserted into the annular locking portion 32, the upper end portion of one first side wall portion 14 </ b> A of the trunk frame 11 disposed at the closing position CL is also inside the annular locking portion 32. Inserted. In this state, even if one first side wall portion 14A is not held in the closed position CL by the fixing means 16, it is assumed that the one first side wall portion 14A moves from the closed position CL to the open position OP. It can be blocked by the stop 32. That is, the upper lid 13 of the present embodiment also plays a role of holding one first side wall portion 14A at the closed position CL in a state where the upper opening of the body frame 11 is closed.
The annular locking portion 32 configured as described above is formed in a similar shape that is slightly larger than the body frame 11 having a square cylindrical shape. Further, the height dimension (dimension in the Z-axis direction) of the annular locking portion 32 is set sufficiently smaller than the dimension in the axial direction of the body frame 11.

The pair of bearing plate portions 3 are each formed in a plate shape, and are provided so as to overlap the inner surface sides of the pair of first side wall portions 14 of the body frame 11 facing each other. The pair of bearing plate portions 3 arranged in this way supports the pair of protruding portions 103 of the core 102 from below in a state where the roll-like object 100 is accommodated inside the trunk frame 11.
Each bearing plate portion 3 of the present embodiment has a notch 41 that is recessed from the upper end thereof. The notch 41 penetrates in the plate thickness direction of the bearing plate portion 3. In the present embodiment, the notch 41 is formed in a slit shape that extends downward from the upper end of the bearing plate portion 3. Furthermore, since the protruding portion 103 of the core 102 is in contact with the lower end of the notch 41, the lower end of the notch 41 is formed in a semicircle corresponding to the cylindrical shape of the core 102. Thereby, the bearing plate part 3 can support the protrusion part 103 stably.

Only one notch 41 described above is formed in the bearing plate portion 3 of the present embodiment. For this reason, in the packaging box 1 of this embodiment, only one roll-shaped object 100 is arranged inside the same trunk frame 11.
The above-described bearing plate portion 3 may have a thickness that can stably hold the protruding portion 103. For this reason, the bearing plate portion 3 made of a corrugated cardboard material is configured by, for example, stacking a plurality of corrugated cardboard materials, or by arranging two or more corrugated cardboard materials at intervals in the axial direction of the core 102. It is good to be done. Further, the corrugated board material forming the bearing plate portion 3 may be configured by, for example, stacking a plurality of sheet-like liners and sandwiching a corrugated core between adjacent liners.

  The bearing plate portion 3 of the present embodiment is detachably provided to the box body 2. The bearing plate portion 3 is stacked on the inner surface side of the first side wall portion 14 by being sandwiched between a pair of second side wall portions 15 facing each other in a state where the body frame 11 is formed in a square cylindrical shape, for example. Held in the same position. The bearing plate portion 3 is also sandwiched between the pair of protrusions 23 in a state where the lower end of the bearing plate portion 3 is in contact with the bottom surface 21 a of the lower lid 12, thereby overlapping the inner surface side of the first side wall portion 14. Held in the same position. For this reason, the insertion recessed part 42 for inserting a pair of protrusion part 23 is formed in the both sides (corner part) of the lower end part of the bearing plate part 3.

In a state in which the roll-like object 100 is accommodated in the packaging box 1 of the present embodiment configured as described above, the pair of protruding portions 103 of the winding core 102 are respectively inserted into the notches 41 of the bearing plate portion 3, and the notches 41 Is supported by the bearing plate portion 3.
Thereby, the roll-shaped object 100 is accommodated in the packaging box 1 in a suspended state. That is, the roll-like object 100 is accommodated inside the packing box 1 so that the roll-like object 100 does not contact the bottom surface 21 a of the lower lid 12 and the top surface 31 b of the upper lid 13. In order not to bring the roll-shaped object 100 into contact with the bottom surface 21a of the lower lid 12 or the top surface 31b of the upper lid 13, the height position of the lower end of the notch 41 with which the protruding portion 103 abuts may be set appropriately. In order to appropriately set the height position of the lower end of the notch 41, for example, the height of the inside of the packaging box 1 from the bottom surface 21a of the lower lid 12 to the top surface 31b of the upper lid 13, and the roll-shaped object 100 The diameter dimension may be taken into consideration.

Further, in the state where the roll-shaped object 100 is housed in the packaging box 1 as described above, the protrusion direction tip of each protrusion 103 of the winding core 102 supported by the bearing plate portion 3 is arranged at the closing position CL. It faces the inner surface of one first side wall portion 14A and the inner surface of the other first side wall portion 14. Here, although the protrusion direction front-end | tip of each protrusion part 103 may contact the inner surface of the 1st side wall part 14 like the example of illustration, it does not need to contact, for example.
Thus, the roll-shaped object 100 accommodated in the packaging box 1 is not exposed to the outside.

Next, a method for taking out the roll-like object 100 accommodated as described above from the packing box 1 will be described.
In order to take out the roll-like object 100, the packaging box 1 is arranged in advance so that the axial direction of the roll-like object 100 is oriented in the horizontal direction. Then, the upper lid 13 is removed from the box body 2 as shown in FIG. At this time, the upper lid 13 may be moved upward with respect to the box body 2.
Next, as shown in FIG. 6, one first side wall portion 14A of the trunk frame 11 is rotated from the closed position CL to the open position OP. Further, one bearing plate portion 3 disposed on the one first side wall portion 14 </ b> A side is removed from the body frame 11 and the lower lid 12. Thereby, the axial direction edge part of the roll-shaped object 100 is exposed to the outward of the box main body 2 from the opening between a pair of 2nd side wall parts 15. FIG.
Then, the roll-like object 100 is moved by moving the roll-like object 100 in the horizontal direction by moving the roll-like object 100 in the axial direction of the roll-like object 100 with respect to the trunk frame 11 and the lower lid 12. The outer frame 11 is taken out.

According to the packaging box 1 of the present embodiment, when the roll-like object 100 is taken out, it is not necessary to lift it upward as in the prior art. It is sufficient if there is a space (particularly the height of the space) that can accommodate the box 1. Moreover, the installation which lifts the roll-shaped object 100 becomes unnecessary. That is, the roll-shaped object 100 can be easily taken out without being restricted by the structure or equipment of the building.
Furthermore, according to the packaging box 1 of this embodiment, even if the size of the roll-shaped object 100 accommodated in the packaging box 1 is large, it is possible to remove the upper lid 13 covering the upper side of the roll-shaped object 100 from the trunk frame 11. Easy. Furthermore, since it is easy to move one first side wall portion 14A from the closed position CL to the open position OP, the roll-like object 100 can be easily taken out.

Moreover, according to the packaging box 1 of this embodiment, since the roll-shaped object 100 can be taken out without cutting off the 1st side wall part 14 of the box main body 2, the packaging box 1 after taking out the roll-shaped object 100 is reused. It is also possible to do.

  Furthermore, according to the packaging box 1 of the present embodiment, the second sidewall portions 15 of the trunk frames 11 that are adjacent to each other overlap with each other in a state in which the plurality of trunk frames 11 are arranged. Can be increased. In this embodiment, since the trunk frame 11 is made of corrugated cardboard material, it may be bent and deformed by receiving a large external force. However, by increasing the rigidity of the second side wall part 15, the second side wall part 15 is bent and deformed. The body frame 11 can be held in a rectangular tube shape while being suppressed. Since the second side wall part 15 is formed larger than the first side wall part 14 in the body frame 11 of the present embodiment, it is very useful to increase the rigidity of the second side wall part 15.

  Furthermore, according to the packaging box 1 of the present embodiment, the trunk frame 11 can be folded, and the lower lid 12 and the upper lid 13 that hold the trunk frame 11 in a rectangular tube shape are detachable from the trunk frame 11. For this reason, after taking out the roll-shaped object 100 from the packaging box 1, the trunk frame 11 can be folded by removing the upper lid 13 and the lower lid 12 from the trunk frame 11. Therefore, the packaging box 1 can be stored and transported in a compact manner.

Furthermore, according to the packaging box 1 of this embodiment, the lower end part of the trunk frame 11 is hold | maintained from the inner surface side of the trunk frame 11 by a pair of protrusion part 23, and the trunk frame 11 is hold | maintained at square cylinder shape. It becomes possible.
Moreover, in this embodiment, a pair of protrusion part 23 is distribute | arranged at intervals in the sequence direction of a pair of 2nd side wall part 15. As shown in FIG. For this reason, when the roll-shaped object 100 is taken out by moving the roll-shaped object 100 in the axial direction of the roll-shaped object 100 with respect to the body frame 11 and the lower lid 12 of the box body 2, the pair of protrusions 23 are pulled by the roll-shaped object 100. It doesn't hang. That is, the roll-like object 100 can be taken out more easily.

  Moreover, according to the packaging box 1 of this embodiment, since the bearing board part 3 is detachable with respect to the box main body 2, the several types of bearing board part 3 from which the shape of the notch 41 differs is selected suitably, and a box It can be attached to the main body 2.
