[Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
As shown in FIG. 2 and FIG. 3, a container-like cushioning material 1 is formed by integrally molding a resin sheet by vacuum molding or the like to form a substantially uniform thickness, and accommodates and holds a packaged product V that is a precision instrument. It is. That is, the outer peripheral side wall surface 2 having a rectangular cross section in plan view, the upper wall surface 3 bent in the horizontal direction from the upper end of the outer peripheral side wall surface 2, and the packaged product bent downward from the inner edge portion of the upper wall surface 3 The peripheral side wall surfaces 5A to 5D forming the opening surface 4 having a substantially rectangular shape in plan view to which V can be fitted, and the bottom wall surface 6 continuously formed at the lower ends of the peripheral side wall surfaces 5A to 5D, The peripheral side wall surfaces 5A to 5D and the bottom wall surface 6 form a container-shaped storage portion 7 in which the lower part of the packaged product V is stored. Since the buffer material 1 is formed by integrally forming a resin sheet by vacuum molding, the outer peripheral side wall surface 2 and the peripheral side wall surfaces 5A to 5D are respectively formed with draft angles α for extracting the mold upward. Yes.

On the other hand, the packaged product V has, for example, a substantially rectangular parallelepiped shape that can be fitted into the storage portion 7, and a concave portion Vb is formed on a side surface Va along the storage direction.
On the side wall 5A facing the recess Vb of the cushioning material 1, an engagement rib 8 is formed at a predetermined position corresponding to the recess Vb of the packaged product V along the storage direction (vertical direction in the figure). ing. As shown in FIG. 1, the engaging rib 8 connects the ¼ spherical inlet end 8 a, the back end 8 b continuing to the bottom wall surface 6, the inlet end 8 a and the back end 8 b. The entrance end 7 a is in contact with the upper wall surface 3 and has a length H substantially corresponding to the height of the storage portion 7. Further, a line-shaped thin portion 8d is formed in the circumferential direction at a position 1 / 2H in the length direction of the engagement rib 8.

  In this storage portion 7, is the distance L between the peripheral side wall surface 5A in which the engagement rib 8 is formed and the opening 4 of the peripheral side wall surface 5B facing the same as the thickness W between the side surfaces Va in which the concave portions Vb are formed? Or slightly shorter than L ≧ W. In addition, the packaged product V is positioned in the front-rear direction of the figure by the peripheral side wall surfaces 5C and 5D facing each other.

  Therefore, when the product to be packaged V is inserted into the storage portion 7, the draft angle α also acts so that the lower corner portion of the side surface Va of the product to be packaged V comes into contact with the body portion 8 c of the engagement rib 8, and the engagement rib 8 Is pushed outward, the engaging rib 8 is bent outwardly around the thin-walled portion 8d, and is recessed into a V-shaped concave shape when viewed from the side. Then, when the packaged product V is landed on the bottom wall surface 6, the inlet end 7 a is not depressed and remains in the projecting state, fits into the recess Vb of the packaged product V, positions the packaged product V, and comes off. It is configured to stop.

As shown in FIGS. 4 and 5, a cushioning material 1 for packing a packaged product V such as a VTR camera, which is a precision instrument, into a packaging box 1 is a box body 11 a of a packaging box (packaging body) 11. After storing the storage box 12 for parts at the bottom, a cushion flap 11b that is inserted and placed in a state in which the packaged product V is stored on the storage box 12 and urges the packaged product V downward is provided. The opening / closing lid 11c is closed and packed.

  The cushioning material 1 is bent outward along the bottom side of the outer peripheral side wall surface 2 to form a narrow landing wall 2a, and the reinforcing groove portion 2b is vertically formed on the outer peripheral side wall surface 2 at predetermined intervals in the circumferential direction. The landing wall 2a and the reinforcing groove 2b are formed to buffer the impact in the vertical direction and the impact from the surroundings. Further, the storage portion 7 is formed with a rectangular concave buffer step 6a on the bottom wall surface 6 to buffer the impact in the vertical direction.

  The engagement rib 8 is formed at a position facing the hole Vc formed in the side surface Va of the packaged product V, and the packaged product V is positioned on the peripheral side wall surface 5C facing the engagement rib 8. The convex-shaped part 13 for this is formed. The convex portion 13 is formed in a block shape having a flat contact surface 13a, but may be a convex vertical rib or a protrusion as long as it has a shape corresponding to the packaged product V. In addition, the distance L between the contact surface 13a of the convex portion 13 and the peripheral side wall surface 5A is equal to or slightly shorter than the thickness W of the side surface Va having the hole Vc of the packaged product V so that L ≧ W. ing. Thereby, the packaged product V inevitably comes into contact with the body portion 8c of the engagement rib 8 during storage, and the engagement rib 8 can be bent into a concave shape. Further, the inlet end 8 a of the engaging rib 8 is formed so as to protrude from the upper wall surface 3 from a slightly lower position.

  In the above configuration, when the packaged product V is inserted into the storage portion 7 from above, the lower corner portion of the side surface Va of the packaged product V is brought into contact with the engagement rib 8 and the trunk portion 8c of the engagement rib 8 is formed. The engaging rib 8 is pushed outward together with the peripheral side wall surface 5A, and the engaging rib 8 is bent around the thin portion 8d and is invaginated into a V shape in side view. Then, the entrance end 8a is left in a protruding state, and the packaged product V is engaged with the hole Vc of the packaged product V in which the entrance end 8a is stored in the storage state where the product V is landed on the bottom wall surface 6. The product V is prevented from coming off while being positioned.

  In addition, in the said embodiment and Example, although the engagement rib 8 was made into one, multiple may be sufficient. Moreover, you may form in the several location of 5 C of other surrounding side wall surfaces and other surrounding side wall surfaces 5B and 5D which oppose.
