  In recent years, environmental issues have attracted attention, and interest in technologies based on the premise of recycling resources is increasing. Furthermore, such a technique is required not only to enable recycling of resources but also to give consideration to reducing the environmental cost related to recycling. Further, even for a packaging box having a mechanism for buffering an impact force as described above, the entire packaging box is required to be formed of a single structural material in order to reduce environmental costs. It has become like this. However, if the entire packaging box 900 that holds the packaging body 910 in Patent Document 1 in a suspended state is formed of a single structural material, the ability to buffer the impact force becomes insufficient, and the packaging box 900 is covered during transportation. There was a problem that the package was damaged.

  This invention solves the subject mentioned above, and provides the packaging box which can be formed with a single structural material while having a high impact buffering capability.

  In order to solve this problem, a packaging box according to the present invention includes an inner box that supports a packaged body, an outer box that houses the inner box, and an outer box that is supported by the outer box and arranged for buffering the inner box. And the inner box, the outer box, and the packing body are formed of a single type of structural material, and the packing body includes a plurality of columnar portions that support the inner box. The columnar part is characterized in that an elastic part is provided on a part of the inward surface on the side supporting the inner box.

  According to this, the packing body is arranged away from the inside of the inner box inside and outside the inner box and has the columnar part provided with the elastic part, so that the impact force applied from the outside to the packing box. Is transmitted, the impact force is buffered by elastic deformation or plastic deformation of the columnar portion at a position away from the packaged body, so that a large impact force is not transmitted to the packaged body. Further, since the inner box, the outer box, and the packing body are formed of a single type of structural material, the environmental cost of the packing box can be reduced even when a large amount is processed in a factory or the like. Therefore, it has the effect that it can be formed with a single structural material while having a high impact buffering ability.

  Further, in the packing box of the present invention, the columnar portion is provided with two first openings symmetrically on both sides of the inward surface, and each of the first openings is on the inward surface side. It has the 1st opening end part formed along the ridgeline, and the said elastic part makes the said 1st opening end part an edge part, It is characterized by the above-mentioned.

  According to this, since the elastic portion is adjacent to the two first openings, the structure is weaker than the surroundings, and the impact force is easily concentrated from the surroundings. Then, when an impact force is applied to the packaging box from the outside, the impact force is dispersed by the elastic deformation of the elastic portion and has an effect of being efficiently diffused.

  Further, in the packing box of the present invention, the columnar portion is provided with a second opening on a side surface of the inward surface, and the second opening is formed along a ridge line on the inward surface side. The second opening end is formed, and the elastic portion has the second opening end as an end.

  According to this, since the elastic portion is adjacent to the second opening, the structure is weaker than the surroundings, and the impact force is easily concentrated from the surroundings. Then, when an impact force is applied to the packaging box from the outside, the impact force is dispersed by the elastic deformation of the elastic portion and has an effect of being efficiently diffused.

  In the packing box of the present invention, the columnar portion is provided with a third opening on a side surface of the inward surface, and the third opening is parallel to the ridge line on the inward surface side. A third opening end portion formed along the imaginary line, and formed in a quadrangular shape having the third opening end portion as one side, and a plurality thereof are arranged at intervals in the direction along the imaginary line. It is characterized by being.

  According to this, since at least four corners of the third opening portion where the impact force is likely to concentrate are arranged on the extension line of the third opening end portion, the columnar portion extends along the extension line of the third opening end portion. Easily break. Therefore, when the impact force from the outside is transmitted to the columnar portion, the impact force is greatly buffered by bending a wide region of the columnar portion along the extension line of the third opening end portion.

  Further, in the packing box of the present invention, the columnar portion is provided with two fourth openings symmetrically on both sides of the inward surface, and the fourth opening is a ridge line on the inward surface side. And has a fourth opening end portion formed in a hexagonal shape with the fourth opening end portion as one side, and the elastic portion has the fourth opening end portion as an end portion. It is said.

  According to this, since the elastic part is adjacent to the two fourth openings, the structure is weaker than the surroundings, and the impact force tends to concentrate from the surroundings. Then, when an impact force is applied to the packaging box from the outside, the impact force is dispersed by the elastic deformation of the elastic portion and has an effect of being efficiently diffused.

  In the packing box of the present invention, the columnar part has a fifth opening provided on the same plane as the fourth opening, the fifth opening has a hexagonal shape, and the fourth opening. It arrange | positions at intervals from the part and is provided along the edge part by the side of the said outer box.

  According to this, the columnar portion has a structure in which the surface on which the fourth opening and the fifth opening are provided is weak, and the impact force is easily concentrated from the periphery. And when the impact force from the outside is transmitted to the columnar part, the impact force is greatly buffered by folding a wide region of the columnar part starting from the corners of the fourth opening and the fifth opening. There is an effect.

  The packing box of the present invention is characterized in that the inner box, the packing body, and the outer box are formed of a cardboard material.

  According to this, since the processing cost of the cardboard material is low, the environmental cost for processing the packaging box is reduced.

  The packaging box of the present invention is composed of a single type of structural material, and the packaging body is arranged away from the inside of the packaging body inside and outside the inner box, and has a columnar portion provided with an elastic portion. . Thereby, when the impact force applied from the outside is transmitted to the packaging box, the impact force is buffered by elastic deformation or plastic deformation of the columnar portion at a position away from the packaged body. A large impact force is not transmitted to the packaged body. As described above, it is possible to provide a packaging box that has a high impact buffering capacity and can be formed of a single structural material.

The third packing body 80 is arranged such that the abutting end portion 81 a abuts against the upper end portion of the side wall 11 a of the first inner box 11 while being supported by the support end portion 11 c of the first inner box 11. Further, the contact end portion 81 b is disposed in contact with the upper end portion of the side wall 11 b of the first inner box 11. Further, the sixth columnar portion 84 is disposed above the uppermost end portion of the packaged body stored in the first inner box 11 and away from the packaged body. The third package 90 is incorporated into the outer box 20 in the same manner as the third package 80 is incorporated into the outer box 20. Thus, the package 100 is arranged away from the inside and outside of the inner box 10 from the packaged body. After the inner box 10, the packaged body, and the package 100 are assembled into the outer box 20, the upper surface of the outer box 20 is sealed.

  Next, a mechanism in which the first columnar portions 32 and 33 and the fifth columnar portions 82 and 83 buffer an impact force applied from below to the lower surface of the packaging box 1 will be described with reference to FIG. When an impact force is applied from below to the lower surface of the packaging box 1, the impact force is disposed in contact with the lower surface of the outer box 20 constituting the lower surface of the packaging box 1 shown in FIG. Is transmitted to the first columnar portions 32 and 33 via the base portion 31. In the first columnar portions 32 and 33, the peripheral portions of the first opening portions 32b provided symmetrically on the two sides (Y1 direction and Y2 direction) of the inward surface 32a are structurally weak. . Therefore, a part of the impact force transmitted to the first columnar portions 32 and 33 is concentrated on the peripheral portion of the first opening 32b. As described above, the first elastic portion 32d disposed adjacent to the first opening portion 32b is easily bent upward and downward. Therefore, the first columnar portions 32 and 33 diffuse the impact force concentrated on the peripheral portion of the first opening portion 32b to the peripheral cardboard material when the first elastic portion 32d is elastically deformed (vibrated). The remaining impact force transmitted to the first columnar parts 32 and 33 and not dispersed by the first elastic part 32d is passed through the inner box 10 disposed in contact with the inward surface 32a, and the upper end of the inner box 10 is reached. Is transmitted to the fifth columnar portions 82 and 83 disposed in contact with the portion (support end portion 11c). The fifth columnar portions 82 and 83 are the same as the fourth opening portion 82b and the peripheral portion of the fourth opening portion 82b provided symmetrically on the two sides (Y1 direction, Y2 direction) of the inward surface 82a. The portion around the fifth opening 82e provided on the surface is structurally weak. Therefore, a part of the impact force transmitted to the fifth columnar portions 82 and 83 is concentrated on the peripheral portion of the fourth opening 82b and the peripheral portion of the fifth opening 82e. As described above, the third elastic portion 82d disposed adjacent to the fourth opening 82b is easily bent upward and downward. Therefore, the first columnar portions 32 and 33 diffuse the impact force concentrated on the peripheral portion of the fourth opening 82b to the surrounding cardboard material by the third elastic portion 82d being elastically deformed (vibrated). As described above, the fifth columnar portions 82 and 83 have a surface on the side where the fourth opening 82b and the fifth opening 82e are arranged on the same plane, and the corners of the fourth opening 82b and the fifth opening. It is easy to break with the corner of 82e as a starting point. Therefore, the first columnar portions 32 and 33 are bent starting from the corners of the fourth opening 82b and the corners of the fifth opening 82e, and are plastically deformed, so that the peripheral portions of the fourth opening 82b and the fifth The impact force concentrated on the peripheral portion of the opening 82e is buffered.

  Next, with reference to FIGS. 4 to 7, 14, and 15, a mechanism in which the second columnar portions 35 and 36 buffer the impact force applied from the X1 direction toward the outer surface of the packaging box 1 on the X1 direction side is used. I will explain. FIG. 14 is an enlarged view for explaining an initial state in the cross section of FIG. 4 in the portion E shown in FIG. FIG. 15 is an enlarged view for explaining a state after the second columnar part 35 is bent with the corner of the third opening 35e as a starting point in the same cross section as FIG. When an impact force is applied from the X1 direction toward the outer surface on the X1 direction side of the packaging box 1, the impact force is one of the outer boxes 20 constituting the outer surface on the X1 direction side of the packaging box 1 shown in FIG. Part and the base 34 disposed in contact with the outer box 20 to be transmitted to the second columnar parts 35 and 36. The second columnar portion 35 includes a peripheral portion of the second opening 35b provided on the side surface of the inward surface 35a and a periphery of the third opening 35e provided on the side surface of the inward surface 35a. The site is structurally weak. Therefore, a part of the impact force transmitted to the second columnar part 35 is concentrated on the peripheral part of the second opening 35b and the peripheral part of the third opening 35e. As described above, the second elastic portion 35d disposed adjacent to the second opening 35b is easily bent in the X1 direction side and the X2 direction side. Therefore, the impact force concentrated on the peripheral portion of the second opening 35b is diffused to the peripheral cardboard material by the second elastic portion 35d being elastically deformed (vibrated). As described above, in the second columnar portion 35, the surface on the side where the third opening 35e is provided is easily bent starting from the corner of the third opening 35e. Therefore, the second columnar portion 35 is in an initial state where the surface on which the third opening 35e is provided is linear as shown in FIG. 12 when the impact force is concentrated on the peripheral portion of the third opening 35e. 13 is deformed into a bent state with the corner of the third opening 35e shown in FIG. 13 as a starting point. At this time, the second columnar portion 35 bends a large region along the imaginary line 35f shown in FIGS. 6 and 7, and is greatly plastically deformed. Therefore, the impact force concentrated on the peripheral portion of the third opening 35e is greatly buffered. Is done.

  The impact force applied from the X2 direction toward the outer surface on the X2 direction side of the packaging box 1 is the same mechanism as the impact force applied from the X1 direction toward the outer surface on the X1 direction side of the packaging box 1 is buffered. The description is omitted because it is buffered.

Next, a mechanism for buffering the impact force applied by the third columnar portion 42 and the fourth columnar portion 43 from the Y2 direction toward the outer surface of the packaging box 1 on the Y2 direction side will be described with reference to FIGS. 4 and 5. explain. When an impact force is applied from the Y2 direction toward the outer surface on the Y2 direction side of the packaging box 1 shown in FIGS. 4 and 5, the impact force is the outer box constituting the outer surface on the Y2 direction side of the packaging box 1. 20 is transmitted to the third columnar portion 42 of the second packaging body 40 via a part of the base 20 and the base portion 41 of the second packaging body 40.
Further, it is transmitted to the fourth columnar portion 43 of the second package 40. The third columnar portion 42 is structurally weak at the peripheral portion of the first opening portion 42b provided symmetrically on the two sides of the inward surface 42a. Therefore, a part of the impact force transmitted to the third columnar part 42 is concentrated on the peripheral part of the first opening 42b. As described above, the first elastic portion 42d disposed adjacent to the first opening 42b is easily bent in the Y1 direction side and the Y2 direction side. Therefore, the third columnar part 42 finely divides the impact force concentrated on the peripheral part of the first opening 42b by elastically deforming (vibrating) the first elastic part 42d, and the peripheral part of the first elastic part 42d. Is diffused into the corrugated cardboard material. As for the 4th columnar part 43, the peripheral part of the 1st opening part 43b symmetrically provided in the surface of the both sides of the inward surface 43a is weak structurally. Therefore, a part of the impact force transmitted to the fourth columnar portion 43 is concentrated on the peripheral portion of the first opening 43b. As described above, the first elastic portion 43d disposed adjacent to the first opening 43b is easily bent in the Y1 direction side and the Y2 direction side. Therefore, the fourth columnar portion 43 diffuses the impact force concentrated on the peripheral portion of the first opening 43b to the peripheral corrugated cardboard material when the first elastic portion 43d is elastically deformed (vibrated). The impact force transmitted to the third columnar part 42 of the second package 40 and not completely dispersed by the first elastic part 42d is passed through the inner box 10 disposed in contact with the third columnar part 42. It is transmitted to the third columnar portion 42 of the second packing body 60 disposed in contact with the opposite side surface of the inner box 10. The impact force that is transmitted to the fourth columnar portion 43 of the second package 40 and cannot be dispersed by the first elastic portion 43d passes through the inner box 10 disposed in contact with the fourth columnar portion 43. 10 is transmitted to the fourth columnar portion 43 of the second packing body 60 disposed in contact with the opposite side surface.

  The impact force applied from the Y1 direction toward the outer surface on the Y1 direction side of the packaging box 1 is the same mechanism as the impact force applied from the Y2 direction toward the outer surface on the Y2 direction side of the packaging box 1 is buffered. The description is omitted because it is buffered.

  Thus, the packaging box 1 of 1st Embodiment of this invention is supported by the inner box 10 which supports a to-be-packaged body, the outer box 20 which accommodates the inner box 10, and the outer box 20, and with respect to the inner box 10 And a package 100 arranged for buffering.
