The outer case 8 is a substantially rectangular parallelepiped member that accommodates the packaged product 9. For example, the outer case 8 is a cardboard member formed in a box shape by bending. In FIG. 2, the outer case 8 is indicated by a virtual line.

  In the following description, the portion between the longitudinal ridge portion 92 between two adjacent outer side surfaces 91 in the packaged product 9 and the edge portion of the outer side surface 91 on both sides of the longitudinal ridge portion 92 is referred to as a longitudinal ridge region 92a. .

  The packing material 1 is disposed between the vertical ridge region 92 a and the outer side surface 91 of the packaged product 9 and the inner side surface 81 of the outer case 8. 1 and 2, they are arranged between the bottom surface 90 of the packaged product 9 and the bottom plate upper surface 80 of the outer case 8, and between the upper surface 93 of the packaged product 9 and the top plate lower surface 82 of the outer case 8. The display of other packing materials is omitted.

  In the following description, a conventional packing material different from the packing material 1 is referred to as a reference packing material. The reference packing material may include a vertical frame member for the vertical ridge 92 that extends in the vertical direction along the vertical ridge 92 between the four outer side surfaces 91 of the packaged product 9.

  In the reference packing material, the vertical frame member protects the vertical ridge portion 92 of the packaged product 9 and supports the stacked load to prevent the outer case 8 from being crushed. The vertical frame member is prepared separately from the side surface packing material and the upper surface packing material that protect the outer side surface 91 and the upper surface 93 of the package 9, respectively.

  By the way, in order to simplify packing work and unpacking work, it is required that the number of parts constituting the packing material 1 is small. Moreover, it is desirable that the packing material 1 is not bulky before the packing operation and after the unpacking operation.

  The packing material 1 can reduce the number of components and has a structure that is not bulky before the packing operation and after the unpacking operation. Hereinafter, the structure of the packaging material 1 will be described.

  The packing material 1 includes a plurality of vertical plate portions 11 and 12, a plurality of side buffer portions 16, and a vertical frame portion 13. In the present embodiment, the plurality of vertical plate portions 11 and 12 include one first vertical plate portion 11 and two second vertical plate portions 12.

  The plurality of vertical plate portions 11 and 12 are flat plate-like portions arranged along the inner side surface 81 of the outer case 8 and facing the outer side surface 91 of the packaged product 9. The two second vertical plate portions 12 are arranged so as to face the outer side surfaces 91 on both sides of the one outer side surface 91 of the packaged product 9 that the first vertical plate portions 11 face each other.

  For example, it is conceivable that each of the plurality of vertical plate portions 11 and 12 is a flat corrugated cardboard member. As shown in FIG. 4, the plurality of vertical plate portions 11 and 12 are formed continuously with the bent portion 1p as a boundary.

  That is, as shown in FIG. 3, one flat plate-like base material including a plurality of vertical plate portions 11, 12 is a crease at the boundary between the first vertical plate portion 11 and each of the two second vertical plate portions 12. It is bent along 1a. As a result, a plurality of vertical plate portions 11 and 12 are formed that are continuous with the bent portion 1p along the crease 1a as a boundary.

The plurality of side buffer parts 16 include a first side buffer part 16 a provided in the first vertical plate part 11 and a second side buffer part 16 b provided in the second vertical plate part 12.

  Each of the side buffer parts 16 has a top surface 16p along the outer side surface 91 of the packaged product 9 in a state where the packaging material 1 is inserted between the outer case 8 and the packaged product 9. The plurality of side surface buffer portions 16 are crushed according to the force applied from the side to the outer case 8, thereby reducing the impact applied to the outer side surface 91 of the packaged product 9.

  It is conceivable that each of the side buffer parts 16 is a laminated cardboard bonded to the surface of each of the vertical plate parts 11 and 12. The laminated cardboard has a structure in which a plurality of plate-like cardboard pieces are bonded in a laminated state. For example, it is conceivable that each of the side buffer parts 16 has a structure in which a plurality of the cardboard pieces parallel to the vertical plate parts 11 and 12 are laminated. It is also conceivable that each of the side buffer parts 16 has a structure in which a plurality of the cardboard pieces are stacked along a plane perpendicular to the vertical plate parts 11 and 12.

  The vertical frame portion 13 is a portion facing the vertical ridge portion region 92 a of the packaged product 9. As shown in FIGS. 2 and 3, the vertical frame portion 13 has a vertical gap from the lower end 131 along the bottom plate upper surface 80 of the outer case 8 to the upper end 132 along the top plate lower surface 82 at a position facing the vertical ridge portion 92. It has the main pillar part 13a formed without.

  The vertical frame portion 13 is formed by a combination of the first convex portion 14 and the second convex portion 15 that are formed so as to protrude from the surface of the edge portion of the first vertical plate portion 11 and the second vertical plate portion 12 that are disposed adjacent to each other. It is configured.

A plurality of second protrusions 15. The plurality of first protrusions 14 and the plurality of second protrusions 15 are provided at different positions in the vertical direction.

  In the present embodiment, some of the plurality of first convex portions 14 are formed in series with the first side surface buffer portion 16a. Similarly, some of the plurality of second convex portions 15 are formed in series with the second side surface buffer portion 16b. However, it is also conceivable that all of the plurality of first convex portions 14 are formed separately from all of the plurality of first side buffer portions 16a. Similarly, it is conceivable that all of the plurality of second convex portions 15 are formed separately from all of the plurality of second side surface buffer portions 16b.

  When the one base material including the plurality of vertical plate portions 11, 12 is bent along the crease 1 a at the boundary between the first vertical plate portion 11 and the second vertical plate portion 12, the plurality of first convex portions 14. A part 15 a of the plurality of second protrusions 15 is fitted between the parts, and a part 14 a of the plurality of first protrusions 14 is fitted between the plurality of second protrusions 15. Thereby, the part 14a of the some 1st convex part 14 and the part 15a of the some 2nd convex part 15 which mutually fitted form the main pillar part 13a.

  In other words, the main column portion 13a of the vertical frame portion 13 has a laminated structure in which the portions 14a of the plurality of first convex portions 14 and the portions 15a of the plurality of second convex portions 15 are alternately arranged without gaps in the vertical direction. (See FIGS. 3 and 4).

  The main column portion 13a supports the stacked load and prevents the outer case 8 from being crushed when a plurality of outer cases 8 are stacked.

  For example, it is conceivable that the plurality of first protrusions 14 and the plurality of second protrusions 15 are the laminated cardboard bonded to the first vertical plate portion 11 and the second vertical plate portion 12, respectively. In this case, the laminated corrugated cardboard constituting each of the first convex part 14 and the second convex part 15 has a structure in which a plurality of the corrugated cardboard pieces whose longitudinal direction is the eye direction are bonded in a laminated state. Thereby, the main pillar part 13a strong with respect to the external force of the vertical direction is comprised. The eye direction is the longitudinal direction of the cavity in the truss structure of the cardboard.

  In addition, the remaining portions 14b of the plurality of first protrusions 14 and the remaining portions 15b of the plurality of second protrusions 15 oppose the adjacent portions of the vertical ridge portion 92 in the vertical ridge portion region 92a of the packaged product 9. . Portions other than the main pillar portion 13 a in the vertical frame portion 13 prevent the positional deviation of the packaged product 9.

  In the packing material 1, the vertical frame part 13 which exhibits the function of the said vertical frame member in the said reference packing material, and the some side surface buffer part 16 are integrally formed. Therefore, if the packaging material 1 is employ | adopted, the number of components can be decreased. In particular, since the plurality of vertical plate portions 11 and 12 are formed continuously with the bent portion 1p as a boundary, the number of components is further reduced.

  Furthermore, the packaging material 1 can be easily assembled from a relatively thin flat shape component to a three-dimensional finished product facing the plurality of outer side surfaces 91 of the packaged product 9. Similarly, the three-dimensional packaging material 1 can be easily disassembled into flat parts.

  Therefore, the packing material 1 can be stored and discarded in a state where it is not bulky before the packing operation and after the unpacking operation.

  Further, in the present embodiment, the main pillar portion 13a has a laminated structure in which the portions 14a of the plurality of first protrusions 14 and the portions 15a of the plurality of second protrusions 15 are alternately arranged without gaps in the vertical direction. Have. In this case, the first vertical plate portion 11 and the second vertical plate portion 12 can be easily bent at the position of the boundary between the first convex portion 14 and the second convex portion 15 in the vertical direction. Therefore, even if the main pillar portion 13a is long, the packaging material 1 can be easily disassembled into a more compact state and discarded.
