As is clear from FIG. 14 that schematically shows the inserted state, the shaft portion B inserted into the mounting hole 30 has the edge 28 ′ of the circular hole 28 at the entrance of the mounting hole 30. It is supported over the entire range of 360 °, and further on the inner side of the inlet, it is supported by the side walls 29 ', 29' at the groove end of the rising groove 29 from both sides over substantially the entire length of the insertion depth. The bottom of the mounting hole 30 is supported by the double wall of the folding pieces 26, 26 and the outer lid 24, as is apparent from FIG. 15, so that the mounting hole 30 formed by assembling the lid 22 is Regardless of whether or not there is a stable and reliable insertion state.

When the upper lid portion 22 is assembled from the housed state shown in FIG. 13 to the lid installation state by the above-mentioned procedure, the mounting hole 30 on the upper end side around the upper end side of the shaft portion B is assembled in this assembly. Is formed, the upper end side of the shaft portion B is naturally fitted into the mounting hole 30, and thus the roll-shaped winding material A is provided at both ends of the shaft portion B with the lid portions 22 and 22 of the box body 21. It is supported between the central mounting holes 30, 30. This state is shown in FIG.

From the packaging state shown in FIG. 16, the drawer opening forming portion 31 formed on the one side plate of the box body 21 is punched out based on the rupture line around the drawer opening forming portion 31 to open the drawer opening. A cloth or the like can be pulled out from the roll-shaped wound material A and used through 31a.
