  • Fig. 1 is a perspective view of a state where a product is packaged according to one example of a packaging device according to an embodiment of the present invention
  • Fig. 2 is an exploded view of a schematic configuration of the packaging device.
  • a packaging device 101 includes a pallet 102, which is a mounting base that mounts a product 100 thereon, four supports 103 fitted to four corners of the pallet 102 and arranged in an upright mode, a top plate (lid) 104 mounted on above the respective supports 103, and a surface plate 107 put between the respective supports 103.
  • the pallet 102 is made of resin according to the present embodiment, and fork insertion holes 102a for inserting forks of a forklift are provided therein. Furthermore, a concave portion 102b is formed on the upper surface of the pallet, by depressing the upper surface downward, leaving the outer periphery thereof, and buffer members 108 are arranged in the concave portion 102b. A backing plate 106 is fitted from above of the buffer members 108, so that when the backing plate 106 is fitted, there is no difference in level between the upper surface of the backing plate 106 and the upper surface of the pallet (upper surface of the outer periphery).
  • a fitting portion 102c for attaching the support 103 is provided at four corners of the outer periphery of the pallet.
  • the backing plate 106 has a shape that covers the concave portion 102b on the upper surface of the pallet, and the upper surface of the backing plate (a product mounting surface) is formed in a planar shape without unevenness.
  • a rib (not shown) is provided in a protruding state at the back of the backing plate opposite to the product mounting surface, so that the backing plate is not broken, while maintaining predetermined flexibility with respect to the weight of the article mounted on the backing plate 106.
  • the shape of the rib at the back of the backing plate has diagonally crossing for giving a higher strength in portions where legs of the product (casters or the like) are mounted, as in a case that an image forming apparatus is packaged as a product as shown in Fig.
  • the pallet 102 and the backing plate 106 are formed of the same material (resin according to the present embodiment). When the service life of the pallet 102 and the backing plate 106 comes to an end, the pallet 102 and the backing plate 106 are melted together and can be reused as a recycled material.
  • the buffer members 108 arranged in the concave portion 102b of the pallet 102 are formed of a foam material according to the present embodiment, and two types of materials, that is, a material having a low foaming ratio (a low-foamed buffer member) and a material having a high foaming ratio (a high foamed buffer member) are used.
  • the low-foamed buffer member is arranged in a portion weighted by legs (casters or the like) of the product to be mounted, and the high foamed buffer member is arranged in other portions.
  • the weight applied to the backing plate 106 corresponding to the legs of the product is absorbed by the low-foamed buffer member, and the weight applied to the backing plate 106 corresponding to portions between the legs of the product is absorbed by the high foamed buffer member due to flexure of the backing plate 106, with respect to vertical vibrations at the time of transportation. Accordingly, the impact transmitted to the mounted product can be alleviated.
  • the top plate 104 is mounted on the supports 103, so as to cover the upper part of the product mounted on the backing plate 106.
  • the top plate 104 and the respective supports 103 are detachably engaged with each other by an engaging portion.
  • a central part 104a of the top plate is provided in a protruding state upward from a peripheral part 104b, and the central part 104a and the peripheral part 104b are connected by oblique sides 104c. Since the central part 104a of the top plate protrudes upward from the peripheral part 104b, the strength can be improved more than a case that the top plate has a simple planar shape.
  • the packaging device 101 is constructed such that the pallet 102 can be stacked on the top plate 104 so that the packaging devices 101 can be stacked on each other, and legs 102d of the pallet 102 can be stacked and mounted on the peripheral part 104b of the top plate 104 (Figs. 3 and 12).
  • a positioning unit (not shown) is provided on the front, back, left and right on the surface of the top plate so as to position the pallet 102 when the pallet 102 is mounted on the top plate 104.
  • the top plate 104 can be also stacked on each other. At this time, since the top plate has the shape protruding at the central part, the top plate on the lower side is fitted into the top plate on the upper side, and even if the top plates 104 are stacked in multi stages, the top plates 104 do not collapse.
  • the support 103 includes a first member (upper support) 103a and a second member (lower support) 103b in a substantial L-shape in cross section, and is formed so that the length can be adjusted by superposing an upper support 103a and a lower support 103b on each other.
  • a plurality of engaging holes 131 is provided for each of the upper support 103a and the lower support 103b, and the support 103 is formed (as shown in Fig. 4B) by putting the engaging holes 131 of the both supports together so that the support 103 has a predetermined height (length) and attaching a stopper 133, which is a fixing unit, on the engaging holes 131.
  • four engaging holes 131 are provided in the upper support 103a, and three engaging holes 131 are provided in the lower support 103b.
  • Fig. 5 depicts cross section of the support 103, and a state where the stopper 133 is attached to the support 103.
  • Fig. 6 is a plan view of the stopper 133.
  • Fig. 7 is a perspective view of a state where the stopper 133 is attached to the support 103.
  • the stopper 133 includes two arms (support insertion units) 133a and 133b.
  • An engaging portion 133c that engages with the support to prevent the stopper 133 from coming off is provided at the end of the arm 133a on one side.
