[Example of idea]

The present invention will be described below with reference to embodiments shown in the drawings. In this embodiment, a packaging structure for a telephone is shown as a member to be stored. In the telephone 1 shown in the drawing, a housing 2 of the telephone main body is formed by an upper cover 2a and a lower cover 2b, and a high heel 3 is connected to the bottom surface of the lower cover 2b, and the telephone main body is placed tilted on a table. It was designed to let you do so.
The telephone 1 has a panel 2c fitted on the upper surface of the upper cover 2a.
A dial (not shown) and other operation buttons are installed on the screen.

FIG. 1 also shows a buffer member of such a telephone 1. As shown in FIG. This buffer member 11 includes a ceiling piece 12a, a diagonal piece 12b, a bottom piece 12c, and a diagonal piece 12d.
and an overlapping piece 12e are defined in the strip-shaped cardboard. Furthermore, at one end of this strip-shaped cardboard, there is a notch 14a that vertically crosses the boundary line 13a between the ceiling piece 12a and the diagonal piece 12b, and a cutout 14a that vertically crosses the boundary line 13a between the ceiling piece 12a and the diagonal piece 12b, and a cutout 14a that vertically crosses the boundary line 13a between the ceiling piece 12a and the diagonal piece 12b. 13
A notch 14b that perpendicularly traverses c is formed, respectively. Furthermore, a side piece 12f is attached to the other end of the strip-shaped cardboard, and an overlapping piece 12g is defined at one end thereof. In FIG. 1, reference numeral 13b indicates the boundary line between the diagonal piece 12b and the bottom piece 12c, 13d the boundary line between the diagonal piece 12d and the overlapping piece 12e, and 13e the boundary line between the diagonal piece 12c and the overlapping piece 12f. It shows. Further, in this embodiment, a hole 15 is formed in the center of the boundary line 13d,
A tongue piece 16 is formed at the center of the free end of the ceiling piece 12a, and a notch 17 is formed at a part of the free end of the side piece 12f.

In this buffer member 11, first, the telephone 1 is placed on the bottom piece 12c. Next, the diagonal pieces 12b, 12
d, ceiling piece 12a, overlapping piece 12e and side piece 12
f to the respective boundaries 13b, 13c, 13a,
13d and 13e, and insert the tongue piece 16 into the hole 15.
b, 12d, the ceiling piece 12a, and the overlapping piece 12e constitute a trapezoidal cylindrical member. Further, the locking pieces 18a, 18 are further bent inward by partially bending the portions located outside the notches 14a, 14b.
constitute b.

The buffer member 11 in such a state is
As shown in the figure, the ceiling piece 12a is placed on the long side of the portion located inwardly from the notches 14a and 14b.
A trapezoidal cardboard frame (trapezoidal cylindrical main body) 19 having the bottom piece 12c as a short side is constructed, and the telephone 1 is enclosed by this cardboard frame 19. Further, the above-mentioned locking piece 18 is formed on the band-shaped frame portion 20 that is connected to the opening peripheral portion of this cardboard frame 19.
The inner edges of a and 18b abut against the end of the telephone 1.

Therefore, the telephone 1 housed in the buffer member 11 is held in a state in which movement relative to the buffer member 11 is restricted.

The buffer member 11 that accommodates the telephone 1 in this way
As shown in FIG.
i is brought into contact with the inner wall of the ridge of the packaging box 21, and the ceiling piece 12a and the bottom piece 12c are brought into contact with the inner wall surface of the packaging box 21, and the locking pieces 18a, 18b are brought into contact with the inner wall of the packaging box 21.
The belt-like frame body 20 is stored together with the handset 4 in a state in which the outer edge thereof is in contact with the inner wall surface of the packaging box 21, that is, in a state in which movement with respect to the packaging box 21 is prevented. At that time, the side piece 1 of the buffer member 11
2f is located between the telephone 1 and the handset 4 and prevents them from coming into contact with each other.

FIG. 3 shows the buffer member 11 housed in the packaging box 21. As shown in FIG. In this state, the telephone 1 is positioned so that its top ridges 2d and 2e are separated from the top ridges 21a and 21b of the packaging box 21, and the gap between them, that is, the inside wall 21c of the phone 1 and the packaging box 21, Diagonal pieces 12d and 12b of the cardboard frame 19 are positioned obliquely in the spaces 22 and 23 between 21d.

Therefore, even if an external force in the direction of arrow A acts on the packaging box 21 in FIG. deformation is prevented as much as possible. Furthermore, the stress acting on the cardboard frame 19 due to the external force in the direction of arrow A is distributed to the diagonal piece 12d and the ceiling piece 12a at the ridge 2d, while the stress acting on the cardboard frame 19 at the ridge 2f is distributed to the bottom piece 12c in contact with the packaging box 21. Since this stress is dispersed between the locking piece 18b that is not in contact with the inner wall of the ridge of the packaging box 21, this stress does not affect the ridges 2d and 2f of the telephone 1.

The same thing can be said about the external force in the direction of arrow B in FIG.

Furthermore, with respect to external forces in the directions of arrows C and D in FIG. 21e, 21
Although f is slightly weakened, even if these ridges 21e and 21f are deformed, there are spaces 22 and 23 between them and the telephone 1, so the lower ridges 2f and 2g of the telephone 1 are not affected. Furthermore, the stress acting on the cardboard frame 19 due to the external force in the directions of arrows C and D, for example, the stress due to the external force in the direction of arrow C, is applied to the packaging box 19.
Since this stress is distributed between the bottom piece 12c that is in contact with the telephone 1 and the locking piece 18b that is not in contact with the packaging box 21, this stress does not affect the telephone 1.

Further, the movement of the telephone 1 relative to the buffer member 11 is restricted, and the packaging box 21 of the buffer member 11
Since the movement of the packaging box 21 is prevented,
The case 2 will not be damaged due to movement of the telephone 1 during transportation or the like.

In addition, in the above embodiment, the packaging of the desk telephone 1 is explained, and the telephone 1, that is, the member to be stored is slightly different from a rectangular parallelepiped, but the member to be stored, which is applied to the present invention, is a three-dimensional object having a ridge. It can be anything.

FIG. 4 shows a modification of the box-like packing structure according to the present invention. The buffer member 30 applied to this modification has a trapezoidal cardboard frame (trapezoidal cylindrical body) 31 formed in the center of a strip-shaped cardboard, with the ceiling piece 32a as the long side surface, and Ceiling pieces 32a are formed at both end edges of the opening to be connected to the cardboard frame 31, respectively.
A trapezoidal band-shaped frame portion 31' is formed with the shorter side.

By bringing the inner edge of c' into contact with the end of the member 40 to be accommodated, the member 40 to be accommodated is accommodated with movement relative to the buffer member 30 being restricted.

The buffer member 30 containing the member 40 to be stored in this way is placed in the packaging box 21 as shown in the same figure, with the ridges 32d on both long sides of the cardboard frame 31,
32e is brought into contact with the inner wall of the ridge of the packaging box 21, the ceiling piece 32a and the bottom piece 32f are brought into contact with the inner wall surface of the packaging box 21, and the outer edge of the band-like frame body 31' is brought into contact with the inside of the packaging box 21. It is stored in a state in which it is in contact with a wall surface, that is, in a state in which movement with respect to the packaging box 21 is prevented. At this time, the ridges 32g, 32g, 32h, 32h on both long sides of the strip frame 31' are brought into contact with the inner wall of the ridge of the packaging box 21 in the same manner as the ridges 32d, 32e on the long sides. There is.

In this buffer member 30, the diagonal pieces 32b and 32c of the cardboard frame 31 are connected to the upper ridge portion 21 of the packaging box 21.
a, 21b, and the locking pieces 32b', 32b', 3 of the band-shaped frame body part 31'
2c' and 32c' are the lower ridge parts 21e and 2 of the packaging box 21.
1f, and each ridge part 21a, 21b, 21 of the packaging box 21 is
In response to external forces A, B, C, and D acting on e and 21f, those ridges 21a, 21b, 21c, and 21d
Evenly prevents deformation.

Furthermore, since the movement of the member 40 to be stored relative to the buffer member 30 is regulated, and the movement of the buffer member 30 relative to the packaging box 21 is prevented, the member 40 to be stored may be moved during transportation of the packaging box 21 and may be damaged. There's nothing to do.

[Effect of idea]

As mentioned above, the packaging structure of the box-like object according to the present invention has the ridges of the packaging box reinforced with the buffer member, so that the stored components are protected from external forces acting on the ridges of the packaging box. can do. Further, since movement of the member to be stored relative to the buffer member is regulated and movement of the member to be stored relative to the packaging box is prevented, damage to the member to be stored due to movement within the packaging box can be prevented. Moreover, since the buffer member is composed of one piece,
Complications of packaging work are not introduced.
