The direction in which the short side extends is the second horizontal direction H2 (see arrow H2 in FIG. 1) according to the present invention. And two inner boxes 20A and 20B are accommodated side by side in the horizontal first direction H1. Of these, the relatively small inner box 20A is shown entirely in FIG. The inner box 20A is a resin-molded product having a box-like structure with an open upper surface. For this reason, the side walls 21 and 22 are provided with draft angles, and the entire inner box 20A is slightly narrowed toward the bottom side. . Further, the inner box 20A has a rectangular shape when viewed from above, and the short side of the rectangle is parallel to the horizontal first direction H1 (see arrow H1 in FIGS. 1 and 2), and The long side is accommodated in the outer box 40 so as to be parallel to the horizontal second direction H2 (see arrow H2 in FIGS. 1 and 2).

  From the entire periphery of the opening edge at the upper end portion of the inner box 20A, the flange portion 24 projects toward the side. Inner side engagement protrusions 25 and 25 are projected outward from a pair of side walls 21 and 21 opposed in the horizontal second direction H2 in the inner box 20A. The inner side engaging projection piece 25 stands upright from the center of the left and right sides of the side wall 21 and is formed over the entire vertical direction of the side wall 21. Similarly to the side wall 21, a draft angle is provided on the front end surface 25 </ b> A of the inner side engagement protrusion 25. Further, both the lower end corner and the upper end corner of the inner side engaging protrusion 25 are rounded. Further, the inner side engaging projection piece 25 projects outward from the tip of the flange portion 24, and the upper end portion of the inner side engagement projection piece 25 is continuously reinforced with the flange portion 24.

  The inner side engaging protrusions 25 are provided with backlash prevention protrusions 26 at three positions, ie, positions near both ends in the vertical direction and the center. The backlash preventing protrusions 26 are arranged symmetrically with respect to the inner side engaging protrusions 25 and have a ridge shape extending in the second horizontal direction H2. Further, the upper surface of the rattle prevention projection 26 is horizontal, and the lower surface of the rattle prevention projection 26 is inclined so as to approach the inner side engagement projection piece 25 side downward.

  On the inner bottom surface of the inner box 20A, thin plate-like inner bottom surface cushioning materials 30, 30 are fixed at two positions near both ends in the horizontal second direction H2 (see FIG. 1; however, FIG. Only the inner bottom cushioning material 30 is shown). The inner bottom cushioning material 30 is made of a conductive foamed resin. An inner side cushioning material 28 and an outer bottom cushioning material 48, which will be described later, are similarly made of a conductive foamed resin. Thus, generation of static electricity can be prevented.

  As shown in FIG. 5, on the outer lower surface of the inner box 20A, for example, a hook-and-loop fastener tape 50A known as a registered trademark “magic tape” (corresponding to “box retaining means”, “pile & hook” according to the present invention) is provided. It is pasted. The hook-and-loop fastener tape 50A includes a plurality of hooks on the surface of the tape-shaped fabric, and the back surface is fixed to the outer lower surface of the inner box 20A. The hook-and-loop fastener tape 50A is disposed at the center in the horizontal first direction H1 on the outer lower surface of the inner box 20A and extends from one end to the other end in the horizontal second direction H2.

  As shown in FIG. 2, a buffer material receiving recess 27 is formed at the center of the inner surfaces of the upper ends of the pair of side walls 21, 21 facing each other in the horizontal second direction H <b> 2 in the inner box 20 </ b> A. In addition, a pair of cushioning material accommodating recesses 27 and 27 are formed on the inner surfaces of the upper ends of the pair of side walls 22 and 22 opposed in the first horizontal direction H1 at positions near both ends thereof. These buffer material accommodation recesses 27 are formed by bulging a part of each of the side walls 21 and 22, have a flat rectangular parallelepiped space inside, and are open to the inside and the top side of the inner box 20 </ b> A. A part of the rectangular parallelepiped inner side cushioning material 28 is accommodated and fixed in each cushioning material accommodating recess 27. The inner side cushioning material 28 constitutes “a baggage retaining means” and an “inner cushioning portion” according to the present invention. The inner side cushioning material 28 is partially accommodated in the cushioning material accommodating recess 27, so that the wall thickness is increased and the shock absorption is improved.

  Each inner side cushioning material 28 has an upper surface flush with the upper surface of the flange 24. Further, each inner side cushioning material 28 protrudes inward from the side walls 21 and 22. And the planar shape of the area | region enclosed by the end surface of the protrusion side among these inner side surface shock absorbing materials 28 is a rectangle, The dimension of the short side of the rectangular area is less than 50 [mm], and the dimension of a long side is It is less than 178 [mm]. As a result, when a rectangular parallelepiped electric device 80 (for example, a car stereo) conforming to 1DIN is inserted into the inner box 20A as a luggage, the inner side cushioning material 28 is in close contact with the side surface of the electric device 80 from all sides, and the inner box The electric device 80 can be stabilized in 20A, and the electric device 80 can be prevented from falling into the inner box 20A by the frictional engagement force between the inner side cushioning material 28 and the electric device 80.

  On the other hand, the relatively large inner box 20B is shown entirely in FIG. This inner box 20A differs from the above-described relatively small inner box 20A only in that it is larger in the first horizontal direction H1, and the other configurations are common. Specifically, in this inner box 20B, the short side dimension of the rectangular region surrounded by the end faces of the inner side cushioning material 28 group is less than 100 [mm], and the long side dimension is less than 178 [mm]. Yes. Thus, when a rectangular parallelepiped electric device 90 (for example, a car stereo) conforming to 2DIN is inserted into the inner box 20B as a load, the inner side cushioning material 28 comes into close contact with the side surface of the electric device 90 from all sides.

Accordingly, the side walls 41 and 42 of the outer box 40 are also provided with a draft similar to the side walls 21 and 22 of the inner box 20A, and the entire outer box 40 is slightly narrowed toward the bottom side.

  An intermediate abutment wall 43 projects from the outer surface of the outer box 40 toward the side from a substantially vertical center. A plurality of vertical ribs 44 extending in the vertical direction are provided below the intermediate contact wall 43 on the outer surface of the outer box 40. These vertical ribs 44 have a symmetrical structure with respect to the center line CL1 located at the center in the horizontal second direction H2 in the outer box 40, while the center located in the center in the horizontal first direction H1 in the outer box 40. The structure is asymmetric with respect to the line CL2.

  A plurality of rib insertion grooves 45 are formed on the inner side surface of the outer box 40 so as to correspond to the plurality of vertical ribs 44 from the upper end portion to the intermediate position in the vertical direction. The rib insertion grooves 45 also have a symmetric structure with respect to the center line CL1, but have an asymmetric structure with respect to the center line CL2. When a plurality of outer boxes 40 are stacked up and down, as shown in FIG. 8A, when all the vertical ribs 44 and 44 are aligned in a straight line between the upper and lower outer boxes 40 and 40, Thus, all the vertical ribs 44 of the upper outer box 40 are in a stacking state in contact with the upper surface of the lower outer box 40. On the other hand, when the upper outer box 40 is rotated 180 degrees around the vertical axis and stacked with respect to the lower outer box 40, all the vertical ribs 44 of the upper outer box 40 are attached to the lower outer box 40. It is inserted into all the rib insertion grooves 45. As a result, as shown in FIG. 8B, the lower portion of the upper outer box 40 below the intermediate contact wall 43 is accommodated in the lower outer box 40, and the intermediate contact of the upper outer box 40 is achieved. The nesting state in which the wall 43 is in contact with the upper edge of the lower outer box 40 is established. In the transport box 10 of the present embodiment, in this nesting state, the upper ends of the inner boxes 20A and 20B housed in the lower outer box 40 and the lower ends of the upper outer box 40 face each other with a gap therebetween. It is configured as follows.

  As shown in FIG. 7A, on the pair of inner side surfaces 41A and 41A facing each other in the horizontal second direction H2 of the outer box 40, a plurality of protrusions 47 are arranged at equal intervals in the horizontal first direction H1. Is formed. As shown in FIG. 7B, these ridges 47 extend from the intermediate position in the vertical direction of the outer box 40 to the lower end. Further, every fifth ridge 47 is slightly longer above the other ridge 47, and a portion of these ridges 47 extending above the other ridge 47 is a mark 47M according to the present invention. It has become. Further, the protrusion 47 is formed symmetrically with both inner side surfaces 41A and 41A across the center line CL1, and the mark 47M is also arranged at the same position in the first horizontal direction H1 of both inner side surfaces 41A and 41A. Each protrusion 47 gradually increases in thickness as it goes downward due to the draft.

  The longitudinal grooves between the adjacent ridges 47 in the ridge 47 group described above become a plurality of outer side engagement grooves 46 (corresponding to “outer side insertion engagement portions” according to the present invention). Yes. As shown in FIG. 1, the inner side engaging protrusions 25, 25 of the inner boxes 20 </ b> A, 20 </ b> B are inserted into any outer side engaging groove 46 in each inner side surface 41 </ b> A, so It is positioned at an arbitrary position in the first direction H1. At this time, the backlash preventing protrusion 26 provided on the inner side engaging protrusion 25 is abutted against the inner surface of the outer side engaging groove 46 to prevent backlash in the horizontal first direction H1. In addition, since the lower surface of the rattle-preventing protrusion 26 is inclined, the inner side engaging protrusion 25 can be smoothly inserted using the inclination as a guide.

  A sheet-like outer bottom cushioning material 48 is laid on the entire inner bottom surface of the outer box 40 and is fixed by, for example, an adhesive. Further, a hook-and-loop fastener tape 50B (corresponding to “box retaining means” and “pile and hook” according to the present invention) that can be engaged with the hook-and-loop fastener tape 50A is attached to the upper surface of the outer bottom cushioning material 48. ing. The hook-and-loop fastener tape 50B is formed by applying an adhesive to the back surface of a pile fabric. Then, as shown in FIG. 7A, the hook-and-loop fastener tape 50B is fixed to the outer bottom cushioning material 48 in two rows and extends from one end to the other end of the outer bottom cushioning material 48 in the horizontal first direction H1. It extends. Thus, when the inner boxes 20A and 20B are placed on the outer bottom cushioning material 48, the hook and loop fastener tapes 50B and 50B of the outer bottom cushioning material 48 are disposed at two locations on both ends of the hook and loop fastener tape 50A of the inner boxes 20A and 20B. 50B crosses and comes into contact. Then, a plurality of hooks of one hook-and-loop fastener tape 50A are hooked on the pile of the other hook-and-loop fastener tape 50B at the contact portion, and the inner boxes 20A and 20B are placed on the bottom wall 49 of the outer box 40 via the outer bottom cushioning material 48. (See FIG. 7B).

  The engagement force of these hook-and-loop fastener tapes 50A and 50B is larger than the friction engagement force between the inner side cushioning material 28 of the inner boxes 20A and 20B and the electric devices 80 and 90. Further, the adhesive fixing force between the outer bottom cushioning material 48 and the bottom wall 49 of the outer box 40 (see FIG. 7B) is also the friction between the car stereo 80, 90 and the outer bottom cushioning material 48. It is larger than the engaging force.

  The configuration of the present embodiment is as described above. Next, the effect of this embodiment is demonstrated. When a package is transported by the transport box 10 of the present embodiment, first, the type and number of inner boxes 20A and 20B to be mounted on the outer box 40 are determined according to the type and combination of packages.
