  There is an increasing demand for upgrading the exterior design of automobile parts, so that in the course of transportation and logistics, the surrounding parts and the surface side of the packaged parts will not be inadvertently damaged due to the packaging material. There is a strong demand for it. In order to ensure the stability of the packaged goods during transportation and logistics, the surrounding parts and part of the surface side are in contact with the packing material in the conventional car parts package. In some cases, it is not possible to avoid 100% of the parts being damaged due to contact with the packing material or friction.

  The present invention has been made in view of the above circumstances, and can be packaged in a state in which the peripheral part and the surface side of the packaged part are not in contact with the packaging material at all, and vibration during transportation and distribution It is an object of the present invention to provide a packaging body that can suppress the movement of a part due to, for example, and that can finish a necessary transport and logistics without the part contacting the packaging material. .

  The packaging body according to the present invention is a packaging in which the support members are arranged in multiple stages, and the package is stored in a posture in which the back side is supported by the lower support member between the lower support member and the upper support member. The packaged product is not in contact with either the lower support member or the upper support member on the periphery and surface side of the package, and between the lower support member and the upper support member, The resin sheet covering the package supported by the lower support member is disposed, and the resin sheet is sandwiched between the lower support member and the upper support member in a state where it cannot be freely moved. Features.

  In one aspect of the packing body according to the present invention, a locking projection for locking the resin sheet is formed on the upper surface of the support member, and the resin sheet engages with the locking projection. A hole is formed, and the resin sheet is sandwiched between a lower support member and an upper support member in a state where the hole is engaged with the locking protrusion.

  In the present invention, the support member can be made of any material provided that it has the required cushioning properties and mechanical strength. It may be a foamed resin or a non-foamed resin. Preferably, it is a foamed resin molded product from the viewpoint of moldability and lightness, and more preferably an in-mold foam molded product. More preferably, it is a foamed molded product of a thermoplastic resin. Thermoplastic resins include polystyrene resins, polyolefin resins (eg, polypropylene resins, polyethylene resins, etc.), polyester resins (eg, polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.), polycarbonate resins, polyresins. Examples include lactic acid resins. Among these, it is preferable to use a composite resin containing polystyrene and polyethylene. The magnification of the foam may be set as appropriate in consideration of the weight, shape, etc. of the part to be packaged, but it has good cushioning properties, has a strength that does not buckle, is lightweight and economical, 30 to It is about 50 times (0.033 g / L to 0.020 g / L). Not only foam molding but also vacuum molding and injection molding can be used.

  In this invention, if the material of the said resin sheet is a resin material whose friction resistance between package bodies is smaller than the material of the said supporting member, use of appropriate resin material can be used. Examples include resin materials such as polyolefin resins. More preferably, it is a material such as a polyethylene resin.

  In the packaging body according to the present invention, the packaged product accommodated between the lower support member and the upper support member has only a part on the back side thereof in contact with the support member. The part and the surface side are not in contact with any support member. Therefore, it can avoid that the surrounding part and surface side of a package are damaged by a support member. And the packaged product is in a state where it cannot move because the surface side is pressed by the resin sheet, and the packaged product moves vertically or horizontally even if vibration is applied when transporting the package. It is suppressed to do. Due to the restraining force, it is possible to avoid the peripheral portion and the surface side of the packaged product from coming into contact with the support member during transport or the like. As a result, it is possible to distribute the packaged product to a required location while maintaining high surface design.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of a support member used in the package according to the present invention. In the illustrated example, the support member 10 includes a right support member 10A and a left support member 10B. In this example, the packaged product 50 to be supported by the support member 10 has a symmetrical shape that is curved upward, and therefore supports the right support member 10A that supports the right end side of the packaged product 50 and the left end side. The left support member 10 </ b> B has a mirror-symmetric shape. Hereinafter, the right support member 10 </ b> A will be described, and the left support member 10 </ b> B will be denoted by the same reference numerals and description thereof will be omitted. Of course, when the package 50 is not symmetrical, the right support member 10A and the left support member 10B having different shapes are used.

  In this example, the right support member 10 </ b> A has a shape capable of simultaneously storing three packages 50 having the same shape, and is formed with three back-side receiving portions 11 having the same shape. As shown in FIG. 6, the shape of the front surface side of the back surface receiving portion 11 is a shape along the shape of the back surface side of the packaged product 50, and the right end side of the packaged product 50 rides on the back surface side receiving portion 11. In such a state, the movement of the packaged product 50 is regulated. A vertical wall 12 is erected around the back-side receiving portion 11, and the vertical wall 12 is a peripheral portion of the packing product 50 in a state where the packing product 50 is on the back-side receiving portion 11. It is formed at a position away from 51 by a few millimeters. Therefore, the peripheral part 51 on the right end side of the packaged product 50 is not in contact with the right support member 10 </ b> A in a state where the packaged product 50 is on the back surface receiving part 11.

  The lower surface 13 and the upper surface 14 of the right support member 10A are flat surfaces parallel to each other. As shown in FIG. 6, the upper and lower surfaces 14 of the right and left ends of the package 50 are the right support member 10A and the left support member 10B. In the state where it rides on the back surface side receiving part 11, it is located at a lower level than the highest part 52 of the packaged product 50. An appropriate number (three in the figure) of U-shaped projections 15 are formed in the upper surface 14 on the outer side of the rear surface side receiving portion 11 along the longitudinal direction. A U-shaped groove 16 into which the U-shaped protrusion 15 formed on the right support member 10A, which is positioned at a lower position, can be fitted, is formed at a position corresponding to the protrusion 15.

  A locking projection 17 is formed between the adjacent back surface side receiving portions 11, 11 on the upper surface 14, and does not appear in the figure, but at a location corresponding to the locking projection 17 on the lower surface 13. Is formed with a recessed portion into which the locking protrusion 17 formed on the right support member 10A, which is positioned at the lower position, can be fitted. A rectangular parallelepiped protrusion 18 is also formed at the end of the upper surface 14 in the longitudinal direction. The right support member 10 </ b> A, which is positioned at a lower position, corresponds to the rectangular protrusion 18 on the lower surface 13. A notch 19 is formed in which the formed rectangular parallelepiped protrusion 18 is engaged.

  Further, as shown in FIG. 6, the thickness of the back surface side receiving portion 11 is thinner than the thickness between the bottom surface 13 and the top surface 14, and the back surface portion 20 corresponding to the back surface side receiving portion 11 is a back surface side receiving portion. 11 has the same curved surface shape.

  A procedure for packing the package 50 using the right support member 10A and the left support member 10B having a mirror-symmetrical shape will be described. First, the right support member 10A and the left support member 10B are set on a pallet (not shown) by using a column or the like standing on the pallet as a positioning member at a predetermined interval. The predetermined interval is defined by the length of the package 50 to be packed. The packaged product 50 is arranged so that the right end portion is supported by the set right support member 10A and the left end portion is supported by the left support member 10B. As described above, in this state, the peripheral portions 51 and 51 on the left and right end sides of the packaged product 50 do not contact the support member 10.

  Next, as shown in the plan view of FIG. 3, the resin sheet 60 is arranged so as to cover the top of the three arranged packages 50. Although the thickness of the resin sheet 60 depends on the size and weight of the package 50, it is usually sufficient if it is about 1 to 10 μm. The size of the resin sheet 60 is such that the length in the longitudinal direction, which is the longitudinal direction of the support member 10, is approximately the same as the width in the longitudinal direction of the support member 10, and the lateral width is the right support member 10 </ b> A located opposite to it. It is desirable for the width to be able to cover both upper surfaces 14 and 14 of the left support member 10B.

  Furthermore, when the resin sheet 60 is disposed, the portion that faces the locking protrusions 17 formed on the right support member 10A and the left support member 10B substantially matches the cross-sectional shape of the locking protrusions 17. It is preferable that the hole 61 having the shape described above is formed. Although not shown in FIG. 3, the rectangular parallelepiped protrusion 18 is also formed in a portion that faces the above-described rectangular parallelepiped protrusion 18 when the length in the vertical direction is wider and the resin sheet 60 is disposed. You may make it further form the hole of the shape substantially corresponded in this cross-sectional shape.

  FIG. 6 is a cross-sectional view of the state in which the package 50 is disposed at a predetermined position using the right support member 10A and the left support member 10B as described above, and the resin sheet 60 is disposed (laid) thereon. Shown in As described above, the height of the upper surface 14 of the support member 10 becomes the highest of the packaged product 50 when the packaged product 50 is arranged at a predetermined position using the right support member 10A and the left support member 10B. The height is lower than the portion 52. Therefore, in the example shown in FIG. 6, the surface side of the central portion of the packaged product 50 is in contact with the resin sheet 60.

  After the posture shown in FIG. 6, the right support member 10A having the same shape is oriented on the right support member 10A, and the left support member 10B having the same shape is oriented on the left support member 10B. Stack in the same way. In this posture, the support member 10 on which the packaged product 50 is placed is referred to as a lower support member, and the support member 10 stacked on the lower support member is referred to as an upper support member. Between the lower support member and the upper support member, the back surface side is accommodated in a posture supported by the lower support member, and the peripheral portion 51 and the front surface side of the packaged product 50 are stored in the lower support member. And none of the upper support members. A resin sheet 60 is disposed between the lower support member and the upper support member so as to cover the package 50 supported by the lower support member. By being sandwiched between the upper surface 14 and the lower surface 13 of the upper support member and the upper support member, they cannot move freely. In particular, in the illustrated example, the resin sheet 60 has the holes 61 formed therein engaged with the locking projections 17 formed in the support member 10, and the movement of the resin sheet 60 is further restricted.

  In this state, the whole body may be tightened with a band to form a package, or as shown in FIG. 4, the support members 10 may be stacked in four stages and the packaged product 50 may be stored in three stages. Furthermore, as shown in FIG. 5, it may be stacked in more stages.

  In any case, in the packaging body according to the present invention, the packaged product 50 housed between the lower support member 10 and the upper support member 10 has a part on the back side thereof in contact with the lower support member 10. However, the peripheral portion 51 and the surface side of the packaged product 50 are not in contact with any support member. Therefore, it is possible to avoid the peripheral portion 51 and the surface side of the packaged product 50 from being damaged due to the support member 10. Since the front surface side of the packaged product 50 is pressed by the resin sheet 60, the movement is restricted, and the packaged product 50 can be moved in the vertical direction or the horizontal direction even if vibration is applied when the package is conveyed. It can suppress moving to. Due to the restraining force, it is possible to avoid the peripheral portion 51 and the surface side of the packaged product 50 from coming into contact with the support member 10 at the time of transportation or the like. It is possible to distribute in the future.

  Although not shown, depending on the degree of curvature of the package 50, when the package 50 is arranged on each stage of the support member 10 as shown in FIG. Touching can occur. In that case, the contact can be avoided by increasing the thickness of the support member 10 or by interposing a dummy support member.
