  Next, the operation will be described. In assembling the packaging apparatus, the bottom surface cushioning material 5 is mounted on the tray-type bottom plate 3, the package body 1 is placed thereon, and the top surface cushioning material 4 is mounted on the top surface corner of the package body 1. Then, the tray type top plate 2 is covered from above, and the top surface cushioning material 4 and the bottom surface cushioning material 5 are bound by the band 7 from the outside of the tray type top plate 2 and the tray type bottom plate 3 to be packaged. 1 is packed.

  And the convex part 8 is formed in the upper surface front and back of the top cushioning material 4, and it is set as the shape where the substantially center part of the upper surface of the top cushioning material 4 was dented, and the convex part 9 was formed in the front and back of the bottom cushioning material 5. Since it is formed and has a shape in which the substantially central portion of the upper surface of the bottom cushioning material 5 is recessed, when the entire packaging device is bound by the band 7, it is hung on the left and right sides in the longitudinal direction of the package 1 By tightening the band 7, the front and rear cushioning members 4 and the bottom cushioning member 5 are respectively narrowed at the front and rear sides, and the top cushioning member 4 is a convex portion on the top surface cushioning member 4 as shown in FIGS. 4 and 7. The bottom plate cushioning material 5 is bent so as to swell upward, and the bottom plate cushioning material 5 swells downward as shown in FIGS. 6 and 7. The packaged body is packaged according to the height of the convex portions 8 and 9 each having a depth of the dent. When stacking the top cushioning material 4, the portion receiving the load from above the top cushioning material 4, as shown in FIG. It is the apex part 8a of the part 8, Comprising: The distance L between supports which receives a load becomes large.

  Further, the portion supporting the load by the bottom cushioning material 5 also supports the load at the apex portion 9a of each convex portion 9 as shown in FIG. 6B of the bottom cushioning material 5 through the tray-type bottom plate 3. The distance L is increased, and wobbling of the packaging device can be prevented. In this way, the load is received by the apexes 8a of the top cushioning material 4 of the lower packaged body 1 and the apex parts 9a of the bottom cushioning material 5 of the packaged body 1 stacked on the upper side. The distance L between the supports can be widened, and as shown in FIG. 7, the lower side through the top cushioning material 4 of the lower packaging body 1 and the bottom cushioning material 5 of the upper packaging body 1 Since the contact area corresponding to the flat surface between the upper surface of the tray-type top plate 2 of the packaged body 1 and the lower surface of the tray-type bottom plate 3 of the upper packaged body 1 can be taken, vibration during transportation and stacking storage Thus, it is possible to prevent wobble and load collapse, and there is no need to use an expensive reinforcing member such as a support, and it is possible to obtain a packaging device that has a simple configuration and can prevent wobble and load collapse at a low price.

  In addition to preventing wobbling of the stacking portion, the floor to be placed is placed due to the depression in the substantially central portion of the bottom surface of the bottom cushioning material 5 when the lower packaged body 1 or the stacking body is placed alone. Since the surface is supported by a wide support distance L of the apex portion 9a of the bottom cushioning material 5 and wobble is prevented, vibration during transportation of the truck and the like can be prevented and product failure can be prevented. There is also an effect that quality can be improved.

  Further, in this embodiment, as shown in FIG. 7, the positions of the convex portions of the top cushioning material 4 and the bottom cushioning material 5 are set to the same size, and the vertex portion 8a of the convex portion 8 and the vertex portion 9a of the convex portion 9 are used. Therefore, the load is surely applied by the convex portions 8 of the top cushioning material 4 of the lower packaging body 1 and the convex portions 9 of the bottom cushioning material 5 of the packaging body 1 stacked on the upper side. Therefore, there is an effect that can prevent wobble and cargo collapse.

  Further, the height (the depth of the dent) of the protrusions 8 and 9 is such that when the band 7 is bent, the substantially central portion of the top surface of the top cushioning material 4 and the bottom surface of the bottom cushioning material 5 is bent and expanded as shown in FIG. It is desirable that the height of the projections 8 and 9 be set to be the same as or slightly lower than the height of the projections 8 and 9. Not only the portion but also the vicinity of the center is the size that is substantially in contact with and supported by the tray-type top plate 2 and the tray-type bottom plate 3, so that there is an effect that it is possible to more stably prevent wobble and load collapse.

  In this way, the top cushioning material 4 and the bottom cushioning material 5 that are attached to the top and bottom surfaces of the package body 1 and protect the top and bottom surfaces of the package body 1, and the top and bottom surfaces of the package body 1 A top surface cushioning material 4 and a band 7 that hangs and binds to the body 1 from the outside of the bottom surface cushioning material 5. Since the convex portion 8 and the convex portion 9 are formed on the front and rear of the lower surface of the material 5, and the concave portion has a shape in which a substantially central portion of the upper surface of the top cushioning material 4 and the lower surface of the bottom cushioning material 5 is dented, With an inexpensive configuration, it is possible to prevent wobbling and load collapse when stacking the packaging devices, and it is possible to obtain a packaging device that can prevent wobble and load collapse without using an expensive reinforcing member such as a support. Moreover, since the disassembly after use can be easily disassembled into the top cushioning material 4 and the bottom cushioning material 5 by removing the band 7, there is an effect that it is possible to provide a packaging device suitable for environmental problems such as recycling.

Embodiment 2. FIG.
8 to 13 are views showing a packaging device according to Embodiment 2 for carrying out the present invention. FIG. 8 is an exploded view, FIG. 9 is a perspective view of a cushioning material on the top surface, and FIG. FIG. 11 is a perspective view of the cushioning material on the bottom surface, FIG. 12 is a perspective view of the cushioning material on the bottom surface due to band tightening, and FIG. 13 is a stack of packaging devices. It is principal part sectional drawing at the time. In addition, the same code | symbol is attached | subjected to Embodiment 1 and an equivalent part, and detailed description is abbreviate | omitted. The structure and operation other than those described are the same as those in the first embodiment.

  In the first embodiment, the projections 8 of the top cushioning material 4 and the projections 9 of the bottom cushioning material 5 are flat, but the projections of the top cushioning material 4 of FIGS. 10 and the convex portion 11 of the bottom cushioning material 5, the convex portion 10 and the convex portion 11 are formed in a triangular cross section so as to be higher on the front and back sides of the top surface of the top cushioning material 4 and the bottom surface of the bottom cushioning material 5. Then, like the ridgelines 10b and 11b having a triangular cross-section, the concave side walls (ridgelines) 10b and 11b are opened in a shape in which a substantially central portion of the upper surface of the top cushioning material 4 and the bottom surface of the bottom cushioning material 5 is recessed. You may incline so that it may become wide at the side.

  Even if it does in this way, the effect similar to the said Embodiment 1 is acquired. Further, by tightening the band 7, the front and rear cushioning materials 4 and the bottom cushioning material 5 are respectively squeezed in the front and rear sides, and the top cushioning material 4 is projected on the top surface cushioning material 4 as shown in FIGS. The bottom plate cushioning material 5 is bent downward so that the concave portion between the convex portions 11 on the bottom surface of the bottom cushioning material 5 is downward as shown in FIGS. 12 and 13. A portion that receives a load from above the top cushioning material 4 when stacking the packaged bodies 1 to be packaged due to the height of the convex portions 10 and 11 each having a depth of a dent. Is the apex portion 10a of each convex portion 10 as shown in the explanation line A of FIG. 10 of the top cushioning material 4 through the tray-type top plate 2, and the distance L between supports for receiving the load is further implemented. It becomes wider than Form 1.

  Further, the portion supporting the load by the bottom cushioning material 5 also supports the load at the apex portion 11a of each convex portion 11 as shown in the B lead-out line of the bottom cushioning material 5 in FIG. The distance L is further wider than in the first embodiment, and the wobbling of the packaging device can be further prevented. Further, since the convex portion 10 of the top cushioning material 4 and the convex portion 11 of the bottom cushioning material 5 are triangular, the triangular ridgelines (concave side walls) 10b and 11b are deformed in the horizontal direction by tightening the band 7, and When the top surface of the lower tray-type top plate 2 and the bottom surface of the upper tray-type bottom plate 3 overlap when the packaging devices are stacked, the triangular shape of the convex portions 10 and the convex portions 11 due to the weight of the upper packaging device. Since the ridge lines 10b and 11b of the ridge line are deformed to become horizontal, the ridge lines 10b and 11b of the triangular support point portions allow the support point portions receiving the load to contact with each other over a wider area and receive the load reliably. Therefore, it is possible to more reliably prevent wobbling or collapse of goods during transportation or stacking storage.

  In this embodiment, the concave portions 10b and 11b have a shape in which the central portions of the top surface of the top cushioning material 4 and the bottom surface of the bottom cushioning material 5 are recessed by the convex portions 10 and 11. Although both are formed so as to be wide at the open side, the effect is less than when both are widened, but one of the recesses on the top cushioning material 4 side or the bottom cushioning material 5 side is shown. Only the side wall may be inclined so as to be wide, and even in that case, the effect of preventing the rattling of the packaging device can be obtained similarly.

Embodiment 3 FIG.
FIG. 14 is a diagram showing a packaging device according to Embodiment 3 for carrying out the present invention, and is a cross-sectional view of a main part when packaging devices corresponding to FIG. 13 are stacked. In addition, the same code | symbol is attached | subjected to the same part as Embodiment 1-2, or an equivalent part, and detailed description is abbreviate | omitted. Further, the structure and operation other than those described are the same as those in the first and second embodiments.

  In the said Embodiment 1, the convex part of the convex part 8 of the top | upper surface shock absorbing material 4 and the convex part of the convex part 9 of the bottom face shock absorbing material 5 is shown, and the convex part 10 and bottom face of the top | upper surface shock absorbing material 4 are shown in Embodiment 2. Although the convex part 11 of the shock absorbing material 5 formed in the cross-sectional triangle shape was shown, like the convex part 12 of the top | upper surface shock absorbing material 4 and the convex part 13 of the bottom face shock absorbing material 5 of FIG. You may form in the dent which has the side wall of the inclined shape which deform | transforms so that it may become substantially horizontal by clamping | tightening. Even if it does in this way, the effect similar to the said Embodiment 1-2 is acquired, and the convex surface which is the side wall of the dent of the convex part 12 and the convex part 13 is a large area via the tray type top plate 2 and the tray type bottom plate 3. Therefore, it is possible to more reliably prevent wobbling and collapse of the load during transportation and stacking storage.

Embodiment 4 FIG.
15 to 19 are views showing a packaging device according to Embodiment 4 for carrying out the present invention. FIG. 15 is an exploded view, FIG. 16 is a perspective view of a cushioning material on the top surface, and FIG. FIG. 18 is a perspective view of the cushioning material on the bottom surface, and FIG. 19 is a perspective view of the cushioning material on the bottom surface due to band tightening. In addition, the same code | symbol is attached | subjected to Embodiment 1 and an equivalent part, and detailed description is abbreviate | omitted. The structure and operation other than those described are the same as those in the first embodiment.

  In the said Embodiment 1-3, each height of the convex part 8 and the convex part 9, the convex part 10 and the convex part 11, and the convex part 12 and the convex part 13 of the top | upper surface shock absorbing material 4 and the bottom face buffer material 5 is respectively used. Although the thing made into the same height was shown, as shown to the convex part 14 and the convex part 15 of the top | upper surface cushioning material 4 of FIGS. Alternatively, a dent may be formed in the substantially central portion of the top surface of the top cushioning material 4 and the bottom surface of the bottom cushioning material 5. For example, when the center of gravity position of the front and back of the body to be wrapped 1 is offset from the center due to the components or the like inside the body to be wrapped 1, the top cushion 4 is formed on the side closer to the center of gravity of the body 1 to be wrapped. The height of one convex part 14 is formed higher than the other convex part 15 formed on the side far from the center of gravity of the body 1 to be packaged, and the center of gravity of the body 1 of the bottom cushion 5 is The height of one convex portion 16 formed on the near side is higher than the other convex portion 17 formed on the side far from the center of gravity of the package 1.

  Even if it does in this way, the effect similar to the said Embodiment 1 is acquired. That is, by tightening the band 7, the front and rear cushioning materials 4 and the bottom cushioning material 5 are respectively squeezed in the front and rear side portions, and the top cushioning material 4 has a convex portion 14 on the top surface cushioning material 4 as shown in FIG. The concave portion between the convex portions 15 is bent so as to swell upward, and the bottom plate cushioning material 5 has a concave portion between the convex portions 16 and 17 on the bottom surface of the bottom plate cushioning material 5 as shown in FIG. Although it bends so that it swells below, when stacking the packaged bodies 1 to be packaged due to the height of the convex portions 14 to 17 each having a depth of a recess, a load from above the top cushioning material 4 is applied. The portions to be received are the apex portions 14a and 15a of the respective convex portions 14 and 15 through the tray-type top plate 2 as shown in the explanation line A of FIG. The distance L between the supports is as large as in the first embodiment, and the portion that supports the load with the bottom cushioning material 5 The distance L between the supports for supporting the load at the apexes 16a and 17a of the respective convex portions 16 and 17 as shown in FIG. As well as wide, it can prevent wobbling and collapse of the packaging device.

  Further, as clearly shown by the C explanation leader line and the A explanation leader line in FIG. 17, the height of the convex portion 14 on the side close to the center of gravity position is formed higher than the convex portion 15 on the side far from the center of gravity position. Further, as clearly shown by the D explanation leader line and the B explanation leader line in FIG. 19, the convex portion 16 on the side close to the center of gravity position is formed higher than the convex portion 17 on the side far from the center of gravity position. When the center of gravity of the packaging body 1 is not at the center position, the protrusions 14 and 16 in the direction closer to the center of gravity position have a large crushing margin due to the inclination to the center of gravity naturally occurring due to their own weight. By forming the convex portion 17 higher, the height of the convex portion 14 and the convex portion 15 after occurrence of crushing can be made the same, and similarly, the height of the convex portion 16 and the convex portion 17 can be made the same. In this way, it is possible to reliably prevent wobbling and collapse of the packaging device during vibration during transportation and stacking storage.

Embodiment 5 of the Invention
20 to 24 are views showing a packaging device according to Embodiment 5 for carrying out the present invention. FIG. 20 is an exploded view, FIG. 21 is a perspective view of a cushioning material on the top surface, and FIG. 22 is a tray type. FIG. 23 is a perspective view of the bottom cushioning material when the band is tightened with the top plate omitted, FIG. 23 is a perspective view of the bottom cushioning material, and FIG. 24 is the bottom cushioning material when the band is tightened with the tray-type bottom plate omitted. FIG. In addition, the same code | symbol is attached | subjected to Embodiment 1 and an equivalent part, and detailed description is abbreviate | omitted. The structure and operation other than those described are the same as those in the first embodiment.

  In the fifth embodiment, a groove 18 is formed in a corner portion where the binding band 7 is applied in the convex portion 8 disposed on the top cushioning material 4. The groove 18 is wider than the binding band 7, and the band 7 is hung in the groove 18 from the top of the tray-type top plate 2, so that the apex 8 b of the convex portion 8 is not tightened. Deflection of the top cushioning material 4 is suppressed like a leader line. In addition, a groove 19 is also formed at a position where the binding band 7 is hooked on the convex portion 9 arranged on the bottom cushioning material 5. The groove 19 is wider than the binding band 7, and the band 7 is hung in the groove 19, so that the top portion 9 b of the convex portion 9 is not tightened, and the bottom cushioning material as shown in FIG. Deflection of 5 is suppressed.

  Thus, when the packages 1 packaged by the convex portions 8 and 9 are stacked, the top surface of the lower tray-type top plate 2 and the bottom surface of the upper tray-type bottom plate 3 are flat on each other. A large area can be taken, and the distance between the support points that actually receive the load can be increased. As a result, it is possible to prevent wobbling and collapse of cargo during transportation and stacking storage with a low-cost configuration without using reinforcing members such as support columns. The portions of the tray-type top plate 2 and the tray-type bottom plate 3 where the bands 7 corresponding to the grooves 18 and 19 are hung may be cut out, but when the band 7 is hung, the grooves 18 and 19 are made of cardboard. Therefore, the grooves 18 and 19 can be fastened with the band 7.
