When the wire rod 27 is pulled out of the container body 1, the load of the wire rod winding body 26 is set in the supporting holes 4, 5 of the container body 1.
, And the reel body portion 13, but in the portion of the support hole 4 on the lid 1A side, a double plate structure (four-layer structure) by the inner and outer lid portions 2 and 3, an upper reinforcing plate 10 and auxiliary reinforcement The support holes 5 on the bottom body 1B side are reinforced by the plates 21 respectively.
In the part (2), since the double plate structure (four-layer structure) by the inner and outer lids 2 and 3 and the lower reinforcing plate 16 and the circular reinforcing plate 20 are reinforced respectively, the load of the wire rod winding body 26. It has a structure that can sufficiently withstand.

The load applied to the reel barrel 13 is such that, on the lid 1A side, both ends 2 and 3 of which the tip of the locking claw 14 of the reel barrel 13 is inside and outside, the upper reinforcing plate 10 and the auxiliary reinforcement. The upper and lower inner peripheral surfaces 13A of the reel body 13 are the outer peripheral surfaces of the upper reinforcing plate 10 while being engaged and fixed with the inner and outer cutout slots 6, 7, 12, 23, 24, etc. of the plate 21. 10A is abutted and supported, and on the other hand, on the bottom body 1B side,
The inner peripheral surface 13B of the upper end portion of the reel body 13 has a lower reinforcing plate 16
While being in contact with and supported by the outer peripheral surface 19A of the tooth portion 19, the lower end 15A of the fixed claw 15 is in contact with and supported by the valley portion 18A of the tooth groove 18 of the lower reinforcing plate 16. The structure can sufficiently withstand the load applied to the reel body 13. In the above embodiment, the fixing means for the reel body 13 to the bottom body 1B side has a different structure from the fixing means to the lid body 1A side, but it goes without saying that they may have the same structure.

[0019]

As described above, in the packaging container according to the present invention, the support body is formed in the center of the lid body and the bottom body of the corrugated cardboard container body having a square shape in plan view. A cut line along each side edge of the opening and a circular cut line concentric with the support hole are formed inside the cut line, and the cut line is inserted into the center hole of the wire winding body to be housed on the inner surface of the central portion of the bottom body. Since one end of the reel body is fixedly installed upright, the other end of the reel body is fixed to the lid body, so that when the linear winding body is stored in the container, It also functions as a reel for wire rods. Therefore, since it is not necessary to separately manufacture a reel, the material cost and the manufacturing cost can be reduced by the amount of this reel, and since it can be assembled with an adhesive or the like, the packaging work is easy and the work efficiency is improved. To do. Also, when pulling out the wire rod, the packaging container becomes a reel if a part of the lid is removed along the cutting line,
It can be transported to the site of use in the packaged state, and the wire wound body can be reliably prevented from being damaged, and the work efficiency at the site of use is also improved. Furthermore, because it is entirely made of corrugated board, it can be manufactured at a significantly lower cost than conventional wooden packaging containers, and in particular, it is remarkably better than three- or four-layer corrugated board. Even if a cheap corrugated cardboard having a two-layer structure is used, even if it is used for a wire rod winding body of 120 to 150 kg, there are various effects such that the structure has sufficient strength.
