Means for Solving the Problems

[0007] The pipe packing material according to the first aspect is a pipe packing material for packing a pipe wound body in which a pipe is wound, and includes a first sheet portion corresponding to one side in the axial direction of the pipe wound body, a second sheet portion corresponding to the other side in the axial direction of the pipe wound body, a plurality of first sheet portion radial perforations provided in the first sheet portion and extending in the radial direction from the center, and a plurality of second sheet portion radial perforations provided at positions corresponding to the first sheet portion radial perforations in the second sheet portion and extending in the radial direction from the center, an annular second sheet portion annular perforation, and any one of holes.

[0008] In the pipe packing material according to the first aspect, as an example, the pipe wound body can be packed as follows.

[0009] The pipe packing material can dispose the pipe wound body between the first sheet portion and the second sheet portion. The pipe wound body is disposed between the first sheet portion and the second sheet portion so that the center of the pipe wound body coincides with the center of the first sheet portion radial perforations.

[0010] In the pipe packing material, by cutting a plurality of second sheet portion radial perforations provided in the second sheet portion, a plurality of second sheet portion sheet pieces arranged in the circumferential direction can be formed. Each second sheet portion sheet piece can be wound toward one side (the first sheet portion side) of the pipe wound body.

[0011] In the pipe packing material, by cutting a plurality of first sheet portion radial perforations provided in the first sheet portion, a plurality of first sheet portion sheet pieces arranged in the circumferential direction can be formed.

[0012] Each first sheet portion sheet piece can be wound toward the other side (the second sheet portion side) of the pipe wound body so as to cover the second sheet portion sheet piece wound to one side (the first sheet portion side), and can be fixed to the second sheet portion with an adhesive tape for fixing the sheet piece.

[0013] Then, the corner portion of the packaging material for pipes is wound toward one side of the pipe winding body so as to cover the sheet piece of the first sheet portion wound toward the other side of the pipe winding body, and the tip of the corner portion can be fixed to the first sheet portion with an adhesive tape for fixing the corner portion.

Mode for Carrying Out the Invention

[0061] [First Embodiment] The packing material 10 for pipes according to the first embodiment of the present disclosure will be described with reference to FIGS. 1 to 9.

[0062] In FIG. 2, an annular pipe winding body 14 around which a pipe 12 is wound is shown in a plan view. In the pipe winding body 14, the tape 16 is wound and restrained at three locations so that the wound pipe 12 does not unwind.

[0063] In FIG. 1(A), the packing material 10 for pipes for packing the pipe winding body 14 is shown in a top view, and in FIG. 1(B), the packing material 10 for pipes is shown in a bottom view.

[0064] The packing material 10 for pipes is a bag made of a thermoplastic synthetic resin such as transparent or translucent polyethylene, which is rectangular in plan view, and the left side in the drawing is the opening 18. As the packing material 10 for pipes, a commercially available so-called plastic bag can be used.

[0065] As shown in Fig. 1(A), the pipe packing material 10 includes a first sheet portion 20 corresponding to one axial side of a pipe winding body 14 to be described later, which is the object to be packed, and a second sheet portion 22 corresponding to the other axial side of the pipe winding body 14.

[0066] In the pipe packing material 10 shown in Fig. 1(A), the lower side (the back side of the drawing) is the first sheet portion 20, and the upper side (the front side of the drawing) is the second sheet portion 22. The first sheet portion 20 and the second sheet portion 22 are connected by three sides.

[0067] In the pipe packing material 10, the side opposite to the opening 18 is called the bottom side 24 (also called the bottom appropriately), the side on one side (the upper side in the drawing) having a positional relationship of 90° with the bottom side 24 is called the first side 26, and the side opposite to the first side 26 is called the second side 28.

[0068] In other words, in the pipe packing material 10, the first sheet portion 20 and the second sheet portion 22 are connected by three sides on the bottom side 24 side, the first side 26 side, and the second side 28 side to form a bag.

[0069] In the pipe packing material 10, when the length of the bottom side 24 (the width of the pipe packing material 10) is L1, the lengths L2 of the first side 26 and the second side 28 (the depth of the pipe packing material 10) are longer than the length L1 of the bottom side 24. That is, the pipe packing material 10 is rectangular in plan view.

[0070] Details of the method for packing the pipe winding body 14 will be described later. As shown in Fig. 3, the pipe winding body 14 is accommodated near the bottom side 24 inside the pipe packing material 10.

[0071] As shown in Fig. 1(A), in the pipe packing material 10, a position L1 away from the corner C1 formed by the bottom side 24 and the first side 26 along the first side 26 is P1, a position L1 away from the corner C2 formed by the bottom side 24 and the second side 28 along the second side 28 is P2, a straight line connecting P1 and P2 is defined as a virtual straight line FL, and the center point of a virtual square (regular quadrilateral) 30 formed on the bottom side 24 side (the right side of the drawing) of the virtual straight line FL is called CP.

[0072] (Second Sheet Portion) As shown in FIG. 1(A), on the upper (drawing surface side) second sheet portion 22, a circular second sheet portion annular perforation 32 centered on the center point CP and an X-shaped second sheet portion radial perforation 34 extending linearly in the radial direction from the center point CP toward P1, P2, C1, and C2 are formed. In other words, the second sheet portion radial perforation 34 is formed by arranging perforations inclined with respect to one side of the second sheet portion 22 in an X shape. Note that the second sheet portion annular perforation 32 and the second sheet portion radial perforation 34 are connected to each other.

[0073] As shown in FIG. 1(A), the diameter A of the second sheet portion annular perforation 32 is formed to be smaller than the outer diameter B of the pipe winding body 14 (see FIG. 2). Also, the diameter A of the second sheet portion annular perforation 32 can be formed to be the same as the inner diameter C of the pipe winding body 14 (see FIG. 2), but it may be slightly smaller or slightly larger than the inner diameter C of the pipe winding body 14.

[0074] (First Sheet Portion) As shown in FIG. 1(B), on the first sheet portion 20, a circular first sheet portion annular perforation 36 centered on the center point CP, a first perforation 38A that is in the radial direction from the center point CP and, for example, parallel to the bottom side 24, and a cross-shaped first sheet portion radial perforation 38 composed of a second perforation 38B orthogonal to the first perforation 38A are formed. In other words, the first sheet portion radial perforation 38 is formed in a cross shape by the first perforation 38A parallel to one side of the first sheet portion 20 and the second perforation 38B in a direction orthogonal to one side. Note that the first sheet portion annular perforation 36 and the first sheet portion radial perforation 38 are connected to each other. Also, the cross-shaped first sheet portion radial perforation 38 and the X-shaped second sheet portion radial perforation 34 are shifted by 45° in the rotational direction (see FIGS. 1(A) and 1(B)).

[0075] As shown in FIGS. 1(A) and 1(B), the center point CP of the first sheet portion annular perforation 36 of the first sheet portion 20 and the center point CP of the second sheet portion annular perforation 32 of the second sheet portion 22 are provided at positions facing each other.

[0076] In this embodiment, the perforation is a dotted-line cut processed to facilitate cutting of the sheet portion, or a plurality of small holes formed with intervals. Therefore, in the pipe packing material 10, the portions where the first sheet portion annular perforation 36, the first sheet portion radial perforation 38 of the first sheet portion 20, the second sheet portion annular perforation 32 of the second sheet portion 22, and the second sheet portion radial perforation 34 are formed are each easily separable by hand.

[0077] (Pipe Packing Method for Packing a Pipe Winding Body with a Pipe Packing Material) Next, a pipe packing method for packing the pipe winding body 14 using the pipe packing material 10 of this embodiment will be described.

[0078] (1) Arrangement Step As shown in FIG. 3, the pipe winding body 14 is accommodated in the pipe packing material 10 with the second sheet portion 22 facing upward so that the center of the pipe winding body 14 coincides with the center point CP of the second sheet portion 22. Since the pipe packing material 10 is transparent or translucent, the position of the pipe winding body 14 can be easily confirmed from the outside.

[0079] (2) Second Sheet Portion Sheet Piece Winding Step A plurality of second sheet portion radial perforations 34 in an X shape provided in the second sheet portion 22 are cut to form a plurality of second sheet portion sheet pieces 22A as shown in FIG. 4.

[0080] Next, each second sheet portion sheet piece 22A is wound toward one side (the first sheet portion 20 side) of the pipe winding body 14 as shown in FIGS. 5(A) and 5(B).

[0081] (3) First Sheet Portion Sheet Piece Fixing Step Cut the cross-shaped first sheet part perforation 38 provided in the first sheet part 20 to form a plurality of first sheet part sheet pieces 20A as shown in FIG. 6.

[0082] Next, as shown in FIG. 7, wind the formed first sheet part sheet pieces 20A around the other side (the second sheet part 22 side) of the pipe winding body 14 so as to cover the space between the second sheet part sheet pieces 22A wound around the first sheet part 20 side (not shown in FIG. 7), and fix them to the second sheet part 22 with the sheet piece fixing adhesive tape 48. Thereby, the inner peripheral portion of the pipe winding body 14 can be covered with the first sheet part sheet pieces 20A and the second sheet part sheet pieces 22A.

[0083] (4) Sheet corner fixing step As shown in FIGS. 8 and 9, wind the corner portion 10A of the pipe packing material 10 around the first sheet part 20 of the pipe winding body 14 so as to cover the wound first sheet part sheet pieces 20A, and fix the tip of the corner portion 10A to the first sheet part 20 with the corner fixing adhesive tape 50.

[0084] Through the above steps, a pipe packing product 52 shown in FIG. 9, which is annularly wrapped by the first sheet part 20 and the second sheet part 22 and is easy to unpack, can be obtained. The pipe packing product 52 of this embodiment has a donut shape with a hole formed in the center, is easier to grip than the case where it is not in a donut shape, and has excellent portability.

[0085] Since the pipe packing material 10 of this embodiment is a bag made of a single material, for example, a thermoplastic synthetic resin such as polyethylene, after use, it can be easily recycled by peeling off the sheet piece fixing adhesive tape 48 and the corner fixing adhesive tape 50. The pipe packing material 10 is not limited to being composed of a thermoplastic synthetic resin, and may be composed of paper having excellent recyclability.

[0086] When pulling out the pipe 12 of the packaged pipe winding body 14, the adhesive tape 50 for fixing the corners is removed, and the tip of the pipe 12 can be gripped and pulled out from the central opening of the pipe packaging material 10. In addition, the pipe 12 can be pulled out through the hole formed by cutting the first sheet portion annular perforation 36.

[0087] Thus, with the pipe winding body 14 accommodated in the pipe packaging material 10, the pipe 12 of the required length can be easily taken out. In other words, the pipe package 46 is excellent in the unwindability of the pipe 12.

[0088] Note that, as shown in FIG. 10, the pipe packaging material 10 may be cylindrical with openings 18 on both sides.

[0089] Also, in the pipe packaging material 10, the first sheet portion annular perforation 36 and the second sheet portion annular perforation 32 may be changed to octagons as shown in FIGS. 11(A) and 11(B).

[0090] [Second Embodiment] The pipe packaging material 10 according to the second embodiment of the present disclosure will be described with reference to FIGS. 12 to 19. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

[0091] In FIG. 12(A), the pipe packaging material 10 for packaging the pipe winding body 14 is shown in a top view, and in FIG. 12(B), the pipe packaging material 10 is shown in a bottom view.

[0092] Details of the method for packaging the pipe winding body 14 will be described later. As shown in FIG. 13, the pipe winding body 14 is accommodated near the bottom side 24 inside the pipe packaging material 10.

[0093] (Second Sheet Portion) As shown in Fig. 12(A), on the upper (drawing surface side) second sheet portion 22, a circular second sheet portion annular perforation 32 centered on the center point CP and an X-shaped second sheet portion radial perforation 34 extending linearly from the center point CP in the radial direction toward P1, P2, C1, and C2 are formed. The second sheet portion annular perforation 32 and the second sheet portion radial perforation 34 are connected. Note that the second sheet portion radial perforation 34 of the pipe wrapping material 10 of the present embodiment can also be omitted.

[0094] (First sheet portion) As shown in Fig. 12(B), on the first sheet portion 20, a circular first sheet portion annular perforation 36 centered on the center point CP and a first sheet portion radial perforation 38 extending linearly from the center point CP in the radial direction toward P1, P2, C1, and C2 are formed. Note that the first sheet portion annular perforation 36 and the first sheet portion radial perforation 38 are connected.

[0095] As shown in Figs. 12(A) and (B), the center point CP of the first sheet portion annular perforation 36 of the first sheet portion 20 and the center point CP of the second sheet portion annular perforation 32 of the second sheet portion 22 are provided at positions facing each other.

[0096] (Pipe wrapping method for wrapping a pipe winding body with a pipe wrapping material) Next, a pipe wrapping method for wrapping the pipe winding body 14 with the pipe wrapping material 10 will be described.

[0097] (1) Arrangement step As shown in Fig. 13, the pipe winding body 14 is accommodated in the pipe wrapping material 10 with the second sheet portion 22 facing upward so that the center of the pipe winding body 14 coincides with the center point CP of the second sheet portion 22.

[0098] As shown in Figs. 14(A) and (B), the opening 18 side of the pipe wrapping material 10 is wound toward the bottom side 24 side to make the planar shape of the pipe wrapping material 10 a square or a substantially square as shown in Fig. 14(A), and the wound portion is fixed to the surface of the second sheet portion 22 with an adhesive tape 53 (see Fig. 14(B)).

[0099] (2) First Sheet Portion Sheet Piece Wrapping Step By cutting the second sheet portion annular perforation 32 provided in the second sheet portion 22, a circular second opening 54 is formed at the center of the second sheet portion 22 as shown in FIG. 15.

[0100] Here, a circular second opening 54 is formed by cutting the second sheet portion annular perforation 32. However, a hole (not shown in the figure. A hole similar to the second opening 54) may be formed in the central portion of the second sheet portion 22 in advance. Instead of the second opening 54, as shown in FIG. 25, the first opening 55 may be formed by opening a plurality of second sheet portion sheet pieces 22A formed by cutting the second sheet portion radial perforation 34.

[0101] Next, with respect to the second opening 54, a plurality of first sheet portion radial perforations 38 provided in the first sheet portion 20 are cut, and the first sheet portion sheet pieces 20A shown in FIG. 16 formed by the cutting of the first sheet portion radial perforations 38 are wound toward the second sheet portion 22 side (the other side) of the pipe winding body 14 through the second opening 54 as shown in FIGS. 17(A) and (B). The first sheet portion sheet pieces 20A are preferably fixed to the second sheet portion 22 with the sheet piece fixing adhesive tape 48.

[0102] (3) Sheet Corner Fixing Step As shown in FIGS. 18 and 19, the corner portion 10A of the pipe packing material 10 is wound toward the first sheet portion 20 side (one side) of the pipe winding body 14, the pipe packing material 10 is turned over, and the corner portion 10A is fixed to the first sheet portion 20 with the corner fixing adhesive tape 50 as shown in FIG. 19.

[0103] Through the above steps, an unpacking - easy pipe - packed product 56 shown in FIG. 19, in which the pipe winding body 14 is wrapped in an annular shape by the first sheet portion 20 and the second sheet portion 22, can be obtained.

[0104] The pipe packaging product 56 of this embodiment is also formed in an annular (doughnut shape) as in the first embodiment, so it is easier to grip and has excellent carry-out performance compared to the case where it is not formed in an annular shape.

[0105] Note that, as shown in FIG. 20, the pipe packaging material 10 may be in a cylindrical shape having openings 18 on both sides.

[0106] Also, in the pipe packaging material 10, the first sheet portion annular perforation 36 and the second sheet portion annular perforation 32 may be changed to an octagon as shown in FIGS. 21(A) and 21(B), or may be changed to a quadrilateral (square) as shown in FIGS. 22(A) and 22(B).

[0107] Since the pipe packaging material 10 of this embodiment is a bag made of a single material, for example, a thermoplastic synthetic resin such as polyethylene, after use, it can be easily recycled by peeling off the adhesive tape 53 and so on.

[0108] Note that when pulling out the pipe 12 of the pipe winding body 14 from the pipe packaging product 46, the corner fixing adhesive tape 50 is removed, and the tip of the pipe 12 can be gripped and pulled out from the central opening of the pipe packaging material 10 (for example, the second opening 54 formed in the second sheet portion 22).

[0109] Thereby, with the pipe winding body 14 accommodated in the pipe packaging material 10, a pipe 12 of a required length can be easily taken out through the second opening 54. In other words, the pipe packaging product 46 is excellent in the unwindability of the pipe 12.

[0110] [Other Embodiments] Although one embodiment of the present disclosure has been described above, the present disclosure is not limited to the above, and it goes without saying that various modifications can be made and implemented within the scope not departing from the gist thereof other than the above.

[0111] In the pipe packing material 10 of the first embodiment, the first sheet portion 20 and the second sheet portion 22 formed a bag connected on three sides. However, as shown in FIG. 20, the first sheet portion 20 and the second sheet portion 22 may be separate bodies. When the first sheet portion 20 and the second sheet portion 22 are separate bodies, the three sides of the first sheet portion 20 and the second sheet portion 22 can be joined with an adhesive tape or the like to form a bag shape as in the pipe packing material 10 of the first embodiment. Note that the two sides of the first sheet portion 20 and the second sheet portion 22 may be joined with an adhesive tape or the like to form a cylindrical shape.

[0112] In the pipe packing material 10 of the second embodiment, the first sheet portion 20 and the second sheet portion 22 formed a bag connected on three sides. However, as shown in FIG. 21, the first sheet portion 20 and the second sheet portion 22 may be separate bodies. When the first sheet portion 20 and the second sheet portion 22 are separate bodies, the three sides of the first sheet portion 20 and the second sheet portion 22 can be joined with an adhesive tape or the like to form a bag shape as in the pipe packing material 10 of the second embodiment. Note that the two sides of the first sheet portion 20 and the second sheet portion 22 may be joined with an adhesive tape or the like to form a cylindrical shape.

[0113] Note that both X-shaped perforations and cross-shaped perforations may be formed in the first sheet portion 20 and the second sheet portion 22. Further, the annular perforations may be provided in either one of the first sheet portion 20 and the second sheet portion 22, or may be provided in both. The radial perforations may be three or more, and may be five or more. When pulling out the pipe 12, the annular perforations 36 of the first sheet portion may be cut to form a circular hole (opening), or the annular perforations 32 of the second sheet portion may be cut to form a circular hole (opening).
