The first side plate member 102 may be folded to the bottom member 201 in a state where both the second side plate member 103 and the diaphragm member 105 are folded on the bottom member 201. [ The inner side surface of the first side plate member 102 is positioned to face the outer side surface of the second side plate member 103 while the second side plate member 103 is folded on the bottom member 201, And can be engaged with the first slot 135.

23 is a perspective view showing the second side plate member 203 of the foldable packaging box 100 according to another of the various embodiments of the present disclosure. 24 is a perspective view showing an expanded view of the second side plate member 203 of the foldable packaging box 100 according to another of the various embodiments of the present disclosure. In some embodiments, the second side plate member 203 of the packaging box 100 can be extended in the height direction of the packaging box 100. 23 and 24 illustrate the extension structure of the second side plate member 203, the first side plate member 102 may also be configured to be expandable using the extension structure of the second side plate member 203 Will be readily apparent to those skilled in the art from this disclosure.

23 and 24, the second side plate member 203 may include a receiving groove 231 on one side, for example, an outer side surface thereof, and a auxiliary side plate member 235 accommodated in the receiving groove 231 have. The receiving groove 231 may be shaped to be open to the upper end of the second side plate member 203 while being recessed by a predetermined depth from the outer side surface of the second side plate member 203. In some embodiments, the shape of the receiving groove 231 can be variously changed. 23 and 24 illustrate the structure in which the receiving groove 231 is completely exposed, the receiving groove 231 at the outer side of the second side plate member 203 is at least partly Can be concealed.

The auxiliary side plate member 235 extends from the upper end of the second side plate member 203 in parallel with the second side plate member 203 along the direction of the arrow R shown in Fig. ), And can be taken out and taken out. In some embodiments, the second side plate member 203 may further include a binding rib 237 and a binding groove 233. The coupling ribs 237 protrude from both sides of the auxiliary side plate member 235 and the coupling grooves 233 can be formed on both side walls of the receiving groove 231. In some embodiments, the binding rib 237 and the binding groove 235 may extend in the receiving and extracting directions of the auxiliary side plate member 235, respectively.

While the auxiliary side plate member 235 is received in the receiving groove 231, the binding rib 237 is inserted along the binding groove 233 and guides the auxiliary side plate member 235 in the receiving direction . When the auxiliary side plate member 235 is received in the receiving groove 231, the binding rib 237 is engaged with the binding groove 233 to fix the auxiliary side plate member 235 in the receiving groove 231 .

Fig. 24 shows a state in which the upper and lower surfaces of the auxiliary side plate member 235 shown in Fig. 23 are reversed. In some embodiments, the coupling rib 237 and the coupling groove 233 may be shorter than the receiving groove 231 in the receiving direction of the auxiliary side plate member 235. 24, when the auxiliary side plate member 235 is housed in the receiving groove 231, a part of the auxiliary side plate member 235 is inserted into the second side plate member 203 The protruded state can be maintained.

The extension height of the second side plate member 203 can be set according to the length of the coupling rib 237 and the coupling groove 233 in the storage direction of the auxiliary side plate member 235. [ The auxiliary side plate member 235 may be inserted into the receiving groove 231 to a position where the lower end of the binding rib 237 is interfered with the lower end of the binding groove 233 in the state shown in FIG. Therefore, the longer the length of the coupling groove 233 from the upper end of the second side plate member 203, the smaller the extension height of the second side plate member 203 can be. Similarly, the shorter the length of the coupling groove 233 from the upper end of the second side plate member 203, the larger the expansion height of the second side plate member 203 can be. The length of the coupling rib 237 and the coupling groove 233 can be appropriately designed in consideration of the expansion height of the second side plate member 203 and the force required to fix the auxiliary side plate member 235 have.

By providing the auxiliary side plate member which can be extended as described above, the capacity of the packaging box can be expanded as necessary.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
