Description

The present invention relates to a package used when transporting metal interior and exterior materials without damage or damage.

Generally, corrugated cardboard, single-sided corrugated cardboard, etc. are used for packaging of architectural exterior materials. Corrugated cardboard has liner paper provided on both sides of an uneven core, and single-sided corrugated board is a package in which liner paper is provided only on one side of the core. When packaging architectural exterior materials in corrugated cardboard, the strength of the cardboard itself is high, so the architectural exterior materials to be packed can be protected from impact during transportation. In addition, architectural exterior materials are sometimes transported in packaging using single-sided corrugated cardboard because of the high degree of freedom in packaging formats.

However, cardboard boxes need to be manufactured individually depending on the size of the item to be packed, and it is also necessary to spend a lot of effort on inventory management. If there is still a gap inside, a method of protecting the packaged object using a cushioning material as in Patent Documents 1 and 2 has been proposed. Patent Documents 1 and 2 describe cushioning materials made of corrugated cardboard that are used when packaging a single long product such as a building door or interior material. However, when packing multiple long parts into one package, multiple cushioning materials are required, which may cause space loss or result in an unnecessarily large package. There is.

Patent Document 3 describes an example in which a cushioning material is provided inside the package, but if the object to be packed moves violently inside the package, the cushioning material will be crushed and the strength of the package will be insufficient. It can be said that there is potential and room for improvement. Furthermore, when metal interior and exterior materials made of polyester painted steel sheets are packaged in single-sided cardboard, scratches and shine may occur on the longitudinal ends of the metal interior and exterior materials.

Therefore, in the present invention, in a package used when transporting a long metal interior/exterior material, an uneven core is provided with an uneven shape, a front liner paper is provided on one of the uneven core, and the uneven core is provided with a surface liner paper on one side of the uneven core. To provide a package for packing a long metal interior/exterior material, in which a reinforcing material is provided on the other side of the core in a part in contact with a longitudinal end of the metal interior/exterior material.

Further, the reinforcing material provides a package having an uneven shape.

As described above, in the present invention, by providing reinforcing materials in the portions that contact the longitudinal ends of the metal interior and exterior materials, scratches and shine caused by the packaging cardboard can be avoided at the longitudinal ends of the metal interior and exterior materials. By forming the reinforcing material, the strength of the package itself can be improved.

The metal interior/exterior material 5 consists of a surface material 6, a back surface material 7, and a core material 8. The surface material 6 is, for example, iron, aluminum, copper, stainless steel, titanium, aluminum/zinc alloy plated steel plate, enameled steel plate, clad steel plate, laminated steel plate (PVC steel plate, etc.), sandwich steel plate (vibration damping steel plate, etc.), synthetic resin plate material. , for example, vinyl chloride resin, polycarbonate resin, etc. (of course, including color plates coated with these resins in various colors) are molded into various shapes by roll molding, press molding, etc. The back material 7 is a type of aluminum deposited paper, kraft paper, asphalt felt, metal foil (Al, Fe, Pb, Cu), synthetic sheet, rubber sheet, cloth sheet, plaster paper, aluminum hydroxide paper, glass fiber nonwoven fabric, etc. Alternatively, it may be a laminate of two or more types, a sheet-like material treated with waterproofing or flame retardant treatment, or a material made of the above-mentioned metal steel plate.

The core material 8 is made of a synthetic resin foam such as polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam, etc., and is made of, for example, a resol-type phenol stock solution and hardened foam. The foaming agent and foaming agent are mixed, discharged onto the back side of the surface material 6, and heated to react, foam, and harden to integrate the surface material 6 and the back surface material 7.

To explain the metal interior/exterior material 5 in more detail, the male portion 9 includes a fixing surface 11 , a fitting groove 12 , a fitting piece 13 , and an oblique side 14 . The female portion 10 includes an engaging piece 15, an engaging groove 16, a raised portion 17, a decorative portion 18, and a step 19. Further, a packing may be continuously provided in the engagement groove 16 to improve waterproofness. The packing may be generally commercially available, such as polyvinyl chloride, chloroprene, chlorosulfonated polyethylene, ethylene propylene, asphalt-containing polyurethane, EPM, or EPDM.

FIG. 3 is a perspective view showing the attachment position of the reinforcing material 21 of the package 1 according to the present invention. It is attached at the position where it touches 10. FIG. 4(a) is a front view showing the inside of the package 1, FIG. 4(b) is a longitudinal sectional view of the uneven core 3 and the uneven reinforcing material 4, and FIG. 4(c) is a front view showing the inside of the package 1. 4(d) is a sectional view of the core 3 and the uneven reinforcing material 4 in the lateral direction, and FIG. 4(d) is a sectional view of the package 1 in the longitudinal direction. The package 1 is made by attaching the reinforcing material 21 to the core 20, and then molding the core 20 and the reinforcing material 21 into an uneven shape as shown in FIG. 4(b) in an overlapping state. and an uneven reinforcing material 4. Therefore, as shown in FIG. 4(c), the portion where the uneven reinforcing material 4 is provided has a double structure, and the strength can be increased. Thereafter, as shown in FIG. 4(d), the package 1 is formed by attaching the front liner paper 2.

The package 1 in FIG. 3 has a length of about 800 to 950 mm in the transverse direction, and a length of the reinforcing material 21 in the transverse direction is about 90 to 130 mm. It is preferable that the reinforcing material 21 is provided with a length that takes into consideration the application of the uneven shape. Further, the height of the unevenness is preferably about 3 mm to 7 mm, and can be changed as appropriate depending on the shape of the object to be packed.

Since the metal interior and exterior materials 5 can be produced in lengths of 2,700 mm to 8,000 mm in the longitudinal direction, they can be packaged according to the length of the metal interior and exterior materials 5, and can be individually packaged like cardboard packaging. There is no need to prepare.

FIG. 5 shows a perspective view of the packaging form of the package 1 according to the present invention. After the metal interior and exterior materials 5 are wrapped in the package 1, the longitudinal ends of the package 1 are fixed together with a packing tape 22. The packing tape 22 may be any tape commonly used for cardboard packaging, such as duct tape, cloth tape, or OPP (Oriented PolyPropylene) tape. As shown in FIG. 5(a), the metal interior and exterior materials 5 to be packed are placed with the bottom surface material 6 facing the packing tape 22 (upper) side, and the metal interior and exterior materials 5 in the second row from the bottom. The back material 7 faces upward, and the metal interior/exterior material 5 in the third row from the bottom has the surface material 6 facing upward, and by alternating the orientation of the metal interior/exterior materials 5 to the front and back, It is possible to package the patterns and unevenness formed on the surface material without interfering with each other.

It is preferable that the entire package 1 is finally fixed with a plurality of binding tools 23 as shown in FIG. 5(b). The binding tool 23 is made of a PP band, and is used to prevent the plurality of products from coming apart.

In the metal interior/exterior material 5 in which a polyester coated steel plate is used as the surface material 6, if the uneven reinforcing material 4 is not provided, there is a risk that scratches or shine may occur in the raised portion 17 due to the uneven core 3. . In particular, in the part pressed down by the binding tool 23, the uneven pattern of the uneven core 3 may be transferred to the raised part 17, or the uneven inner core 3 itself may be crushed due to impact during transportation, ensuring sufficient strength as a cushioning material. There is a possibility that you may not be able to do it.

However, by providing the uneven reinforcing material 4 made of craft tape or the like with low surface roughness, it is possible not only to prevent scratches and shine, but also to ensure sufficient strength as a cushioning material or a package.
