Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product packaging method and a packaging box, which are applied to products whose center of gravity is eccentric from the center.

[0002]

2. Description of the Related Art Conventionally, various mechanical products, electric products, etc. are protected from external impacts and at the same time, they are used for transportation and storage by preventing scratches from adhering to the outer casing.
There are a product packaging method and a packaging box in which a packaging box made of cardboard or the like is assembled, and a product to be packaged is stored and held inside the packaging box through a cushioning material such as polystyrene foam for impact absorption.

A conventional packaging box will be described with reference to the drawings.
FIG. 3 is a front sectional view of a conventional packaging box, and FIG. 4 is a perspective view of the same bottom cushioning material. In the figure, α is a packing box, X is a product to be packed, 1 is an assembly box, 2 is a bottom cushioning material, and 3 is a top cushioning material.

A packing box α of the present apparatus example shown in FIGS. 3 to 4.
Is an assembly box body 1 made of corrugated cardboard or the like which is bent and formed so as to be freely assembled into a hollow box shape, and a bottom surface 1 inside the assembly box body 1.
a bottom cushion made of an elastic material such as Styrofoam, which is interposed and mounted between a to the side surface lower part 1b and the product X to be packaged, and the mounting surface 2a is inclined to match the shape of the bottom Xa of the product X to be packaged. The material 2 and the side surface upper portion 1c in the inside of the assembly box 1 are interveningly mounted from the side surface upper portion 1c to the canopy 1d, and the suppression surface 3a of the packaged product X is formed to be inclined according to the shape of the top surface Xb of the packaged product X. The ceiling cushioning member 3 is made of an elastic material such as expanded polystyrene.

In the conventional apparatus example, the product X to be packaged is formed by inclining the placing surface 2a so as to take a substantially vertical standing posture with respect to the installation surface, and the product X to be packaged is held in this posture. The mounting surface 2a of the product X to be packed is inclined so that the thickness db = dmax is maximized at the maximum weight 2p of the bottom cushioning material 2 immediately below the center of gravity Xo.

Since the bottom cushioning material 2 is manufactured so that the thickness db at the maximum weight Xp to which the maximum weight of the packaged product X is applied is maximized, the bottom cushioning material at the maximum weight Xp is maximized. 2, the height d of the assembly box 1 according to the thickness db
Is determined as a derivative.

A product packing method using such a packing box α will be described. First, the assembly box body 1 in the folded state is assembled into a box shape.

Next, the bottom cushioning material 2 is mounted on the inner bottom surface 1a of the assembly box body 1.

Next, the product X to be packed is placed on the bottom cushioning material 2
When it is placed on the placing surface 2a, the product X to be packed has a substantially vertical standing posture.

Further, the ceiling cushioning material 3 is capped on the product X to be packed inside the assembly box 1.

Finally, the canopy 1d of the assembly box 1 is closed, and a series of packing work is completed.

Since the product packaging method and the packaging box of the conventional example employ such means and techniques, the product X to be packaged can be packaged and held inside the assembly box body 1 in a substantially vertical standing posture.

[0013]

However, the conventional product packaging method and the packaging box α have the following drawbacks. First, the product X to be packaged whose center of gravity Xo is displaced from the center position of the product X to be packaged, for example, most of its weight is CR, such as a television receiver.
In the packaged product X that depends on T, the center of gravity Xo exists at a position slightly deviated from the center position of the housing toward the CRT display tube surface side.

In such a case, since the maximum weight 2p immediately below the center of gravity Xo is subjected to the maximum weight, the thickness db of the bottom cushioning member 2 is determined in consideration of the weight of the maximum weight 2p, and Since the mounting surface 2a is formed so as to be inclined so that the packaged product X takes a substantially vertical standing posture, the bottom cushioning material 2
The thickness db of the other part increases more than necessary. As a result, the volume occupied by the bottom cushioning material 2 is increased, which is inferior in space merit and causes an increase in initial cost.

Secondly, in the bottom cushioning material 2 and the top cushioning material 3 made of expanded polystyrene or the like, overpacking, that is, bottom surface more than necessary, despite the optimum thickness having the highest impact absorbing effect exists. The thicknesses db and dt of the cushioning material 2 and the top cushioning material 3 are increased, and the shock absorbing effect is rather decreased.

Here, the present invention provides a product packaging method and a packaging box in which the occupied volume of the cushioning material and the packaging height can be reduced as much as possible while maintaining the same drop impact resistance as the conventional one.

[0032]

As described above, the product packaging method and the packaging box of the present invention can reduce the thickness in the height direction while maintaining the same drop impact resistance as the conventional product packaging method and the packaging box. Therefore, the occupied volume of the packaging material can be reduced, and the height of the packaging box and the manufacturing cost can be reduced, and excellent space and cost advantages can be achieved.

Compared with the conventional overpacking state, that is, the state where the thickness of the cushioning material is excessive, the thickness of the cushioning material can be suppressed to an appropriate value that has the highest impact absorbing effect, and the impact absorbing effect is minimized. There is an advantage that can be enhanced.
