Thus, the support 5 is positioned and fixed so as not to move in the cardboard box 3.

  Next, the effect of the packaging apparatus 2 shown in 1st embodiment is demonstrated. According to this packing device 2, the water conduit 1 wound in a circular shape is accommodated in the corrugated cardboard box 3 so as to be rotatable in the circumferential direction. Thus, the wound water pipe 1 is accommodated in the cardboard box 3 and stored or transported. And when piping the water flow pipe 1, the 1st and 2nd guide materials 8 and 9 and the 3rd and 4th guide materials 11 and 12 are removed from the cardboard box body 3. FIG. Thereafter, when the water pipe 1 in the cardboard box body 3 is pulled out from the outer peripheral side through the drawing hole 3a formed in the cardboard box body 3, the winding of the water pipe 1 in the cardboard box body 3 is performed. It rotates so that the wound winding part 1a is unwound. At this time, the inner rollers 4 and 4 in the cardboard box 3 come into contact with the inner peripheral surface 1b of the winding portion 1a of the water conduit 1 to guide the rotation of the winding portion 1a.

  Then, when the water pipe 1 in the cardboard box 3 is pulled out through the lead-out hole 3a in this way, the water pipe 1 is not twisted because it rotates so that the winding part 1a is unwound. . Therefore, even if the water pipe 1 made of a synthetic resin such as a cross-linked polyethylene or a polybden, which is generally said to be strong, it can be pulled out easily and easily. (For example, inserted into a sheath pipe previously provided along a predetermined piping path).

  Further, the inner rollers 4, 4 that guide the rotation of the winding part 1 a are installed on a pair of facing plates 6, 6, and the support 5 having these facing plates 6, 6 and the inner rollers 4, 4. However, it is accommodated in the corrugated cardboard box 3 in the supporting state that supports the water pipe 1 (the winding part 1a). Thus, the water pipe 1 is supported in the corrugated cardboard box 3 via the facing plates 6 and 6 and the inner rollers 4 and 4.

Moreover, in order to prevent rattling of the water pipe 1 during transportation of the packing device 2, the guide materials 8, 9, 11, 12 are placed in the cardboard box 3, but the water pipe 1 is connected to the cardboard box. Since the guide members 8, 9, 11, and 12 are removed when the pipes are pulled out from the three extraction holes 3a, the rotational resistance of the water pipe 1 is reduced. And since the rotation resistance of the water flow pipe 1 becomes small in this way, this water flow pipe 1 can be smoothly pulled out from the extraction hole 3a. However, the water conduit 1 may be pulled out from the lead-out hole 3a without removing the guide members 8, 9, 11, and 12 from the cardboard box 3. In this case, for example, the first guide member 8 may be fixed to the bottom plate 3e of the cardboard box 3 without fixing the support 5 in the cardboard box 3 with the staples 13 and 13. The support 5 that supports the water pipe 1 can be positioned via the first guide member 8 so as not to move in the cardboard box 3. In this case as well, similarly, the water pipe 1 can be stably accommodated in the cardboard box 3 and the winding portion 1a can be stably rotated.
