[0010] A metal strip coil package according to the present invention will be described below with reference to the drawings. Note that this embodiment is an example of a metal strip coil package according to the present invention, and the present invention is not limited to the configuration of this embodiment. Fig. 1 is a perspective view showing an outline of a metal strip coil packaged in a metal strip coil package according to the present invention. Fig. 2 is a front cross-sectional view showing an outline of a metal strip coil packaged in a metal strip coil package according to the present invention.

[0011] As shown in Figures 1 and 2, a metal strip coil P, which is a coil-shaped product, is placed on a metal pallet for coil-shaped products (hereinafter simply referred to as a pallet) 10 and packaged in a metal strip coil packaging body 30. In this embodiment, the metal strip coil P is a cylindrical coil made of aluminum (or aluminum alloy) strip, but is not limited to aluminum (or aluminum alloy). For example, iron, titanium, or other metals may also be used.

[0012] The pallet 10 has a plurality of legs 11, 11, 11 arranged parallel to each other at a predetermined interval (three in the illustrated example), a coil mounting portion 12 which is a plate-shaped member supported by the legs 11, 11, 11 and has a mounting surface 12a on which the metal strip coil P is placed, and a protrusion 13 which is arranged in the center of the mounting surface 12a and through which the hollow portion P1 of the metal strip coil P is inserted. In this embodiment, the direction in which the legs 11, 11, 11 extend is defined as the X direction, the direction perpendicular to the X axis direction on the same plane as the legs 11, 11, 11 is defined as the Y direction, and the direction perpendicular to the X and Y directions is defined as the Z direction.

[0013] The metal strip coil P is placed with the lower end surface of the metal strip coil P on the coil mounting portion 12 of the pallet 10, with the hollow portion P1 formed along the central axis of the cylindrical metal strip coil P facing the vertical (Z-axis) direction. That is, the metal strip coil P is placed vertically in a state where it is positioned at a predetermined position on the coil mounting portion 12 by inserting the lower end portion of the hollow portion P1 into the protrusion 13.

[0014] (Metal strip coil package 30) Next, the metal strip coil packaging body 30 will be described with reference to Figures 1 to 3. Figure 3 is a diagram showing the main cover and the inner circumferential surface cover.

[0015] The metal strip coil packaging body 30 includes a buffer sheet 31 provided on the mounting surface 12a on which the metal strip coil P is placed, an inner cover 40 that houses the metal strip coil P, a main cover 50 that covers the outer surface of the inner cover 40 in which the metal strip coil P is housed, and a volatile corrosion inhibitor 60.

[0016] The buffer sheet 31 is laid so as to cover the mounting surface 12a, so that the lower end surface of the metal strip coil P to be mounted on the coil mounting portion 12 is directly placed thereon. The buffer sheet 31 has insertion holes 31a through which the protrusions 13 are inserted when the sheet is placed on the mounting surface 12a. In this embodiment, compressed felt is used as the buffer sheet 31, but this is not limited to this. The buffer sheet 31 may be any material that can protect the metal strip coil P, and may be an elastic material, cardboard, or the like. The buffer sheet 31 may also be made up of multiple layers, and may have, for example, a configuration in which at least a portion of the sheet has a water-proof layer.

[0017] The inner cover 40 has a pair of inner end cover portions 41 that cover the upper end surface of the metal strip coil P, an inner peripheral cover portion 42 that covers the peripheral surface of the metal strip coil P, and an inner opening 43 formed at the lower end. The inner cover 40 is a bag-shaped member with an open bottom end, and by placing it over the metal strip coil P, it can cover and contain the entire metal strip coil placed on the pallet 10. The inner cover 40 is preferably made of a breathable and moisture-absorbent material, and is made of a washable material (such as cloth) so that it can be reused. Furthermore, it is more preferable that the inner cover 40 be made of a material that is difficult to charge.

[0018] The inner opening 43 does not need to be configured to be airtight, and the Z-axis direction of the inner cover 40 is formed to be longer than the height of the metal strip coil P placed vertically on the pallet 10.

[0019] The main cover 50 has a main end cover portion 51 that covers the upper end surface of the metal strip coil P when housed in the inner cover 40, a main peripheral cover portion 52 that covers the outer peripheral surface of the metal strip coil P when housed in the inner cover 40, and a main opening 53 formed at the lower end. The main cover 50 is a bag-shaped member with an open bottom end, and by placing it over the metal strip coil P from above, it can accommodate and cover the entire metal strip coil placed on the pallet 10. The main cover 50 is preferably made of a material that is waterproof, water-repellent, and airtight.

[0020] The inner surface of the main end cover portion 51 is provided with pocket-shaped rust inhibitor storage portions 57 for storing volatile rust inhibitors 60, respectively. 1 to 3, the rust inhibitor storage section 57 is provided at the upper end of the main peripheral cover section 52, and is therefore positioned above the hollow section P1 of the vertically placed metal strip coil. The rust inhibitor storage section 57 and the volatile rust inhibitor 60 may be configured to be provided on the outer edge side of the main end cover section 51.

[0021] The main opening 53 is provided with an opening / closing operation device 56 that expands and contracts the opening portion in a purse-like shape. Specifically, the opening / closing operation device 56 is a string-like member that is provided in a loop along the main opening 53, and the main opening 53 can be closed in a purse-like shape by pulling the opening / closing operation devices 56 together.

[0022] The opening / closing operation device 56 is not limited to a drawstring-shaped device as long as it can smoothly and easily reduce the diameter of the main opening 53. For example, the opening / closing operation device 56 may be configured to allow the main opening 53 to be opened by providing a slide fastener 58, a hook-and-loop fastener, a snap button, or the like on the main opening 53.

[0023] As shown in FIG. 1, the slide fastener 58 used as the opening / closing operation tool extends vertically upward from the main opening 53, and is longer than half the vertical height of the metal band coil. According to this configuration, the main opening 53 can be opened larger, making it easier to accommodate the metal strip coil P inside the main cover 50. The slide fastener 58 may also be provided on the inner cover 40 side.

[0024] The volatile rust inhibitor 60 is accommodated in the rust inhibitor accommodation section 57 inside the main cover 50, so that the vaporized rust inhibitor components can be filled inside the main cover 50 in which the metal strip coil P is accommodated and the breathable inner cover 40. In this embodiment, a carboxylic acid-based rust inhibitor is used as the volatile rust inhibitor 60. This volatile rust inhibitor has a high specific gravity, and the vaporized rust inhibitor component diffuses downward. In addition, the vaporized rust inhibitor component has a slight odor. When considering use in food-related applications, a carboxylic acid-based rust inhibitor is more preferable. The volatile rust inhibitor 60 is not limited to a carboxylic acid-based rust inhibitor as long as it can prevent rusting of the metal band coil P. For example, it may be a nitrite-based rust inhibitor, which has a low specific gravity and whose vaporized rust inhibitor component diffuses upward.

[0025] (Packing method) Next, a method for packaging the metal strip coil P using the metal strip coil packaging body 30 will be described with reference to Fig. 4. Fig. 4 is a diagram showing the procedure for packaging the metal strip coil.

[0026] First, the protrusions 13 are inserted into the insertion holes 31a of the buffer sheet 31 to provide the buffer sheet 31 on the mounting surface 12a, and the pallet 10 is supported in a lying position so that the protrusions 13 extend laterally (horizontally). In this state, the metal strip coil P is moved horizontally to insert the hollow portion P1 into the protrusions 13. In this way, the metal strip coil P is positioned on the coil mounting portion 12. This configuration can be seen in FIG. 4(a).

[0027] Next, the pallet 10 is set upright so that the protrusions 13 face vertically, and the lower end surface of the metal strip coil P is placed on the buffer sheet 31 on the coil placement section 12. This causes the lower end surface of the metal strip coil P to be tightly covered by the buffer sheet 31. This configuration can be seen in FIG. 4(b).

[0028] Next, the inner cover 40 is placed over the metal strip coil P to house the metal strip coil P placed upright on the pallet 10 within the inner cover 40. That is, the upper end surface and outer peripheral surface of the metal strip coil P can be covered with the inner cover 40. This configuration can be seen in FIG. 4(c).

[0029] Next, the main cover 50 is placed over the metal strip coil P to house the metal strip coil P housed in the inner cover 40 inside the main cover 50. Thereafter, the opening / closing tool 56 is used to close the main opening 53 in a purse-like shape. This configuration can be seen in FIG. 4(d). As a result, the lower end of the main cover 50 containing the metal strip coil P is covered by the buffer sheet 31, and the main opening 53 is closed in a drawstring-like shape, so that the part of the inside of the main cover 50 that is connected to the outside air through the main opening 53 is minimized.

[0030] Thereafter, the metal strip coil P may be firmly fixed to the pallet 10 by fastening a cable tie to the upper outer peripheral surface of the metal strip coil P and the cable tie that is inserted into the insertion passage 11a of the pallet 10. The metal strip coil P may be fastened to the pallet 10 with the cable tie before being covered with the inner cover 40 or the main cover 50.

[0031] (Action and effect) According to the above-described metal strip coil package 30, anyone can package the metal strip coil P using the metal strip coil package 30 through simple packaging work that does not require any skill. Since the metal strip coil packaging body 30 packages the metal strip coil P in an unsealed state, condensation occurs on the surface of the metal strip coil P after long-term storage. However, because the interior of the metal strip coil packaging body 30 is maintained in an atmosphere containing the rust inhibitor components of the volatile rust inhibitor, the metal strip coil P can be reliably prevented from rusting, corroding, or discoloring. That is, the metal strip coil packaging body 30 can easily package the metal strip coil P while preventing deterioration of the metal strip coil P, such as rust, due to long-term storage.

[0032] By providing an insertion passage 11a in the leg 11 of the pallet 10, it becomes easy to fasten the metal strip coil P placed on the pallet 10 to the pallet 10 side with a cable tie, or to transport the packaged metal strip coil P as is using a transport means such as a forklift or crane.

[0033] Since the volatile rust inhibitor 60 is disposed at the upper part inside the main cover 50, the entire inside of the metal strip coil packaging body 30 can be filled with the vaporized rust inhibitor component. Furthermore, since the volatile rust inhibitor 60 is provided on the upper part of the main cover 50 close to the upper end surface of the metal strip coil P, an atmosphere containing rust inhibitor components can be reliably maintained near the end surface of the metal strip coil P, where rust is most likely to progress.

[0034] Furthermore, since volatile corrosion inhibitor 60 is disposed between main cover 50 and inner cover 40, the odor emitted by volatile corrosion inhibitor 60 can be absorbed by inner cover 40 before it transfers to metal strip coil P. Therefore, the odor of volatile corrosion inhibitor 60 can be efficiently prevented from transferring to metal strip coil P.

[0035] Furthermore, since the above-mentioned metal strip coil packaging body 30 allows the main cover 50, inner cover 40, and buffer sheet 31 to be reused, it is more economical and environmentally friendly than the conventional packaging method in which the metal strip coil P is sealed in vinyl and the vinyl is then disposed of after the packaging is opened. In particular, the inner cover 40 is stained with the oil adhering to the surface of the metal strip coil P and the smell of the volatile rust inhibitor, but since it is made of a water-washable material, it can be washed after packaging and used repeatedly.

[0036] Furthermore, metal strip coil packaging body 30 may be configured so that the interior is filled with the rust inhibitor component of volatile rust inhibitor 60, and is not limited to a configuration in which rust inhibitor storage section 57 for storing volatile rust inhibitor 60 is provided inside main cover 50. For example, volatile rust inhibitor 60 may be provided on the outer peripheral surface of inner cover 40, or gaseous rust inhibitor component may be periodically filled, or rust inhibitor component may be able to be filled into main cover 50 from the outside.

[0037] (Second embodiment) Next, a second embodiment of the metal strip coil packaging body 30 will be described with reference to Fig. 5 and Fig. 6, focusing on differences from the above-described examples. Fig. 5 is a perspective view showing an outline of the metal strip coil packed in the metal strip coil packaging body of the second embodiment. Fig. 6 is a front view showing an outline of the metal strip coil packed in the metal strip coil packaging body of the second embodiment. As shown in Figure 5, the metal strip coil packaging body 30 may be placed vertically on a pallet 10, and a plate-shaped upper cover unit 70 may be further provided on top of the metal strip coil P covered by an inner cover 40 and a main cover 50.

[0038] The upper lid unit 70 has a buffer sheet 71 placed on the upper end surface of the metal strip coil P, and a lid member 72 made of a plate-shaped metal plate placed on the upper surface of the buffer sheet 71. The cover member 72 is not limited to a single plate-like member, but may be a frame-shaped assembly of a plurality of vertical plates extending in the X-axis direction and a plurality of horizontal plates extending in the Y-axis direction.

[0039] The top cover unit 70 and the metal band coil P may be secured to the pallet 10 by a cable tie 15 inserted through the insertion passage 11a of the pallet 10 and a cable tie 15 positioned by an insertion groove 12b formed in the underside of the coil mounting portion 12. The pair of cable ties 15, 15 are arranged so as to intersect in a crisscross pattern in a plan view. This configuration can be seen in FIG. 6.

[0040] (Action and effect) According to the above-described upper lid unit 70, a metal strip coil P can be further placed on the lid member 72 placed on the upper end surface of the metal strip coil P, so that a plurality of metal strip coils P can be stacked vertically. In this case, a buffer sheet 31 may be further provided on the upper surface of the lid member 72. According to this configuration, by stacking the metal strip coils P in the vertical direction, it is possible to store a plurality of metal strip coils P with good space efficiency.
