  Hereinafter, embodiments of the present invention will be described. A conceptual configuration diagram of an embodiment of the present invention is shown in FIG. FIG. 1 is a perspective view of the packaging container 10 viewed from the back side to facilitate understanding. A rectangular back plate 3 is erected from the long side 1a of the base 1 obliquely upward, for example, 58 degrees. Both corners of the opposite side 1b of the long side 1a are cut out in a square shape to form bottom surface cutouts 1L and 1R.

  A column 5 having a lower end substantially at the center of the bottom notch remaining portion 1C is erected vertically, and the upper end of the column 5 is fixed to the back surface of the back plate 3 to support the back plate 3. In addition, a bracing 7 is arranged from substantially the center of the bottom notch remaining portion 1C so as to support the position of the center of gravity of the back plate 3.

  However, the bracing 7 may be omitted. A plurality of large glass substrates 9 are stacked on the back plate 3. The external dimensions of the packaging container 10 are not different from the external dimensions of the conventional packaging container 101.

Next, the operation of the embodiment of the present invention will be described.
FIG. 2A shows a conceptual plan view when the upper side is viewed from the bottom side of the truck bed 100. 2B is a cross-sectional view taken along the line AA in FIG. 2A, and FIG. 2C is a cross-sectional view taken along the line BB in FIG. 2A.

  As shown in the schematic plan view of FIG. 2 (a), the right front of the packaging container 10A is placed on the truck bed 100 with respect to the bottom notch 1L and the bottom notch 1R on the back side of the packaging container 10B. The corner portion 10AR (R indicates that it is the right side) and the corner portion 10CL (L indicates that it is the left side) in front of the left side of the packaging container 10C can freely enter. Therefore, when the packaging containers 10A to 10C are virtually projected onto the floor surface from above, they are arranged in a zigzag shape so as to partially overlap.

  Thereby, even if the depth limit of the loading platform 100 of the general-purpose truck is 10 m, three packaging containers 10 having a width of 3.6 m (10A to 10C) can be placed in series. Therefore, three packaging containers 10 can be loaded at a time, and the transportation efficiency can be increased. For this reason, transportation cost can also be held down.

  As shown in FIG. 3, when the width dimension of the bottom surface notch portions 1L and 1R is x and the depth size is y, the area of the bottom surface notch portions 1L and 1R is both xxy. A space partitioned from the back plate 3 above the surface is defined as a notch space 12, and a volume occupied by this space is defined as a notch volume.

  Further, the size and area of the bottom cutouts 1L and 1R are virtually moved to the right end and the left end of the long side 1a, and the space partitioned between the back plate 3 on the surface is defined by the corners 10L and 10R. The corner space 14 and the volume occupied by this space are defined as the corner volume.

  In the present embodiment, the corner volume is smaller than the notch volume, and the bottom surface shape of the bottom surface notch portions 1L and 1R and the bottom surface shape of the corner portions 10L and 10R coincide with each other. The corner portion 10AR on the right front side of the packaging container 10A and the corner portion 10CL on the left front side of the packaging container 10C can be made to enter toward the bottom cutout portions 1L and 1R of the inside packaging container 10B.

Further, as can be seen from FIG. 2C, the front side ends (sides 1 d just before the dimension y from the back side) of the bottom surface notches 1 </ b> L and 1 </ b> R are located in front of the rear end of the back plate 3.
Note that the bottom surface shape of the bottom surface notch portions 1L and 1R and the bottom surface shape of the corner portions 10L and 10R are not limited to a quadrangle, and may be similar or congruent. Further, the cutout volume may be made to coincide with the corner volume regardless of the shape of the bottom surface.

  In this case, the supporting member can be arranged around the notch volume. In other words, the shape of the partition surface that partitions the notch volume at this time has a congruent relationship with the shape of the partition surface that partitions the corner volume. However, if the corner volume is formed to be equal to or less than the notch volume, the corner portions 10L and 10R can be made to enter the bottom notch portions 1L and 1R, and therefore, a similar relationship or the like may be used.

  In the present embodiment, the column 5 is described as being disposed between the pedestal 1 and the back plate 3. However, as shown in the interior rear perspective view of FIG. 4 and the interior front perspective view of FIG. Instead of this, triangular auxiliary plates 21A, 21B, and 21C may be provided. In this case, the back plate 3 is further reinforced by the triangular shape of the auxiliary plates 21A, 21B, and 21C.

  Even when it is formed so that the inclination of the back plate 3 is smaller than 58 degrees, it has sufficiently strong rigidity. The shape of the auxiliary plate is not necessarily a triangle, and may be formed so as to cut out the back side into a gentle arc shape. As can be seen from FIG. 4, the side 1 d that is the front end of the bottom surface cutouts 1 </ b> L and 1 </ b> R is positioned in front of the rear end of the back plate 3, as in FIG.

  In the present embodiment, three of the packaging containers 10A to 10C are zigzag arranged in series in the horizontal direction. For example, if only the packaging container 10A and the packaging container 10B are transported, only one of the bottom cutout portions 1L and 1R is cut out. It only has to be.

  In addition, as shown in FIG. 4, you may arrange | position the connection member 23 which bridges and connects between the packaging container 10A and the packaging container 10B, and between the packaging container 10B and the packaging container 10C, respectively. The connecting member 23 is bridged on the upper part of the back plate 3, for example. In this case, the entire packaging container can be integrated and stabilized during transportation.
