Description

  The present invention relates to a shock-absorbing packaging device that protects a product from external impact by packaging the product during transportation.

  In a conventional packaging device including an interior material and a packaging box, the product is fixed by the interior material in order to support and fix the product in the packaging box. This interior material is a molded product, and is formed of, for example, resin or paper (pulp mold).

  In addition to the function of fixing the product, this interior material also has a function of absorbing a drop impact when the packaging device is accidentally dropped during transportation. By converting the energy of the drop impact into energy that deforms the interior material, the impact acceleration is reduced and the product is protected.

  At this time, not only the deformation of the interior material but also the deformation of the packaging box has a buffering effect, so that the interior material is chamfered in order to effectively act as a shock absorber for the deformation of both the packaging box and the interior material. In some cases, a space is provided between the packaging box (see, for example, Patent Document 1).

  In such a structure, the amount of deformation at the time of impact absorption is greater in the packaging box than in the interior material. That is, the cushioning effect of the packaging box is increased.

JP 2010-208659 A

  In the above conventional technique, when the impact cannot be absorbed due to the cushioning effect of the packaging box, the deformation due to the impact extends to the interior material. Normally, the interior material is expected to have a cushioning effect like a packaging box by being deformed, but the interior material deformed to a surface (design surface, etc.) that should not be brought into contact with the interior material of the product to be protected from impact. In some cases, the surface of the product may be damaged, and in this case, it is required to have a structure in which the interior material is not deformed as much as possible. This problem tends to occur particularly when the packaging box is dropped from the corner.

  In order to reduce the amount of deformation of the interior material as a countermeasure when dropping from such a corner, it is conceivable to change the material or shape of the interior material and increase the rigidity of the interior material. By reducing, it becomes easy to prevent a design surface etc. from being damaged. However, when the buffering action is reduced, the drop impact acceleration is increased, and the product may be damaged due to an impact exceeding the allowable acceleration applied to the product.

  The present invention has been made in view of the above, and an object of the present invention is to obtain a shock-absorbing packaging device that protects a product from a drop impact without causing damage to the product surface by causing scratches on the product surface.

In order to solve the above-described problems and achieve the object, the present invention provides a shock-absorbing packaging apparatus including an interior material that supports and fixes a product and a packaging box that accommodates the interior material. A plurality of side walls provided with a plurality of side surface support portions for supporting the center portions of each side surface, a bottom surface provided with a bottom surface support portion for supporting the center portion of the lower surface of the product, and a recess for receiving the product, And a notch provided across the side wall and the bottom surface of the recess only at the position corresponding to the corner on the lower surface side of the packaging box, the side wall is inclined with respect to the bottom surface, A space is formed between the ridge formed by the lower surface and the side surface and the interior material . When the interior material is deformed together with the packaging box, the corner formed by the two side surfaces and the lower surface of the product enters the notch. It is characterized by.

  According to the present invention, it is possible to prevent the product from being damaged without causing damage to the product surface and deteriorating the appearance of the product.

  DESCRIPTION OF EMBODIMENTS Embodiments of a buffer packaging device according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment.
FIG. 1 is a cross-sectional perspective view showing a configuration of an embodiment of a buffer packaging device according to the present invention. FIG. 2 is a perspective view of the interior material viewed from the bottom side.

  The buffer wrapping apparatus 1 includes an interior material 21 that supports and fixes the product 31 and a packaging box 10 that houses the interior material 21. The interior material 21 is provided with a chamfered portion 23 along a ridge 27 formed by a lower surface and a side surface of the packaging box 10, and a position corresponding to a corner 28 on the lower surface side of the packaging box 10 is cut away. A notch 22 is formed. The interior material 21 is a molded product having a shell structure, and is made of, for example, a pulp mold using pulp fibers as a raw material. The interior material 21 has a recess 26 whose outer shape at the edge portion is larger than that of the product 31. Ribs 24 as support portions are formed on the inner wall surface of the recess 26 so as to protrude from the periphery to the inside of the recess 26. The product 31 is supported and fixed to the interior material 21 only by a predetermined portion by the rib 24, and a gap 25 is provided between the inner wall surface of the recess 26 and the product 31 except for the predetermined portion.

  By providing the chamfered portion 23, the space 11 is formed between the ridge 27 formed by the lower surface and the side surface of the packaging box 10 and the interior material 21. By setting the space 11 as a deformation region of the packaging box 10 at the time of a drop impact, the corner 28 and the ridge 27 of the packaging box 10 can be positively deformed to obtain a buffering effect.

  However, when a further drop impact force is applied, the deformation of the packaging box 10 is not completed in the space 11 alone, the chamfer 23 is deformed, and the gap 25 between the product 31 and the inner wall surface of the recess 26 is lost. Sometimes. As a result, the deformed interior material 21 hits a portion other than the support portion of the product 31, and the surface of the product 31 may be damaged.

  In order to reduce such damage to the product 31, the notch 22 is provided in the present embodiment, and when the corner 28 on the lower surface side of the packaging box 10 is deformed and the space 11 and the gap 25 disappear, Although the corners of the interior material 21 and the product 31 hit each other, the presence of the notch 22 makes it possible to avoid damage such as scratches on the product 31.

  The shock-absorbing packaging apparatus according to the present embodiment can prevent the interior material from being deformed by the corner on the lower surface side of the packaging box interfering with the interior material when a drop impact is applied without increasing the rigidity of the interior material. Therefore, not only the damage of the product but also the deformed interior material can be prevented from hitting the product and being damaged.

  Because the interior material has a notch in the portion corresponding to the corner on the lower surface side of the packaging box, the packaging box will deform the interior material even if the packaging box and interior material are designed to be smaller than the conventional structure. Thus, it is possible to secure a space that prevents the gap between the interior material and the product from being lost. Therefore, the buffer packaging device can be downsized. By reducing the size of the buffer wrapping device, it is possible to increase the loading rate during distribution, enable efficient transportation, and suppress energy consumption. Moreover, by forming the interior material with a pulp mold, the raw material of the interior material becomes clear, and it is easy to use as a recycled resource or as a recycled material.
