Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device equipped with a CRT (cathode ray tube) such as a color television receiver or a monitor, and particularly to a device for packing and transporting a device whose center of gravity is eccentric to the front. It relates to the device.

[0002]

2. Description of the Related Art Conventionally, a CRT is provided, and the center of gravity is C.
In the case of packaging a device that is biased toward the RT side, such as a television receiver, when housing a housing with a CRT in a cardboard box, insert the CRT tube face forward into the cardboard box to A method has been adopted in which the bottom surface and the side surface, the top surface and the side surface, and the ridge portion where these surfaces intersect are respectively received and fixed by the bottom surface cushioning material and the top surface cushioning material.

FIG. 5 exemplifies such a conventional means. A corrugated cardboard box 31 is constructed so that it can be sealed by folding a bottom surface and an upper surface thereof. Bottom cushioning materials 11 for accommodating the bottom and side surfaces of the housing of the device and top and bottom cushioning materials 21 are similarly provided on the left and right side surfaces of the upper part of the box body. Each cushioning material is formed by molding a foamed resin member into a predetermined shape or a paper cushioning material such as corrugated board or pulp mold.
Further, the corrugated cardboard box and the cushioning material are usually used for transportation from the production factory to the customer's house, and are usually discarded when the transportation is completed.

[0004]

However, the above-mentioned CRT
Occupies 1/2 to ⅔ the weight of a television receiver, and the housing of a device incorporating this CRT requires extremely high strength against drop impact during transportation.
Therefore, it is necessary to use a large amount of high-strength members for the housing body and a large amount of buffer members for the cushioning effect.

Further, in a device such as a television receiver equipped with a CRT, the center of gravity is biased forward, and stacking packaged sets having a biased center of gravity is extremely unstable and may cause a load collapse or a fall. . In addition, the operator is forced to have an unreasonable force and posture when handling the load, which is not preferable in terms of work efficiency and worker's health. On the other hand, after the end of transportation,
At present, these packaging members (corrugated cardboard boxes, cushioning materials, etc.) are discarded, and improvements are required from the viewpoint of waste disposal problems and effective use of resources.

[0006] In view of the above problems, the present invention provides a packaging apparatus which enables reduction in strength and thinning of a casing, elimination or reduction of a cushioning material, ensuring safety during transportation and storage, and reuse of packaging containers. It is provided.

[0007]

In order to solve the above-mentioned problems, the present invention has a bottom cover and a canopy made of synthetic resin, and a rectangular tube-shaped body made of corrugated cardboard, etc. In a packaging container composed of parts, while providing a convex portion having a substantially semicircular cross section along the outer periphery of each bottom lid,
CRT tube surface that is heavy and causes eccentricity of the center of gravity,
It is arranged downward, and the CRT tube surface and the outer periphery of the housing are received and fixed by the bottom lid and the canopy.

It is also possible to supplementarily use a cushioning material between the packaging container and the CRT tube surface or the outer circumference of the casing. In either case, it goes without saying that a material having a high elasticity (for example, polyethylene, polypropylene, etc.) is used for the bottom lid and the canopy.

[0009]

In the above structure, when the packaging container containing the equipment is dropped, the impact of the CRT tube surface, which is the heaviest of the equipment, is directly received by the elastic bottom cover (or through a small amount of cushioning material). And, on average, the housing itself is not subjected to a large impact, and its impact strength can be greatly reduced.

Further, since the elasticity of the synthetic resin bottom lid and canopy can be utilized to absorb the impact at the time of dropping, it is possible to eliminate the conventional cushioning material. It is possible to reduce the amount used. Furthermore, since the position of the center of gravity of the packaging set is changed from the conventional front direction to the downward direction, there is no bias of the center of gravity in the packaged state, and transport and handling can be performed in a stable state. On the other hand, this packaging system is divided into several parts such as bottom lid, canopy, and body part after transportation, and the body part is folded and stored between the bottom lid and canopy. And can be reused as a packaging container.

[0011]

Embodiments of the present invention will now be described with reference to the drawings by using an example of a packaging device for a television receiver. (Embodiment 1) FIG. 1 is an exploded perspective view of a packaging apparatus according to an embodiment of the present invention.

This packaging device comprises a synthetic resin bottom cover 1 and a canopy 2, a rectangular tube-shaped body 3 made of paper or resin, and several connecting parts for connecting them. Four
And a protective sheet 5 for preventing damage to the device. In the above packaging device, the packaging of the device is performed by the following procedure. First, the CRT tube surface 2 is placed downward on the protective sheet 5 laid in the center of the bottom lid 1. Next, the body portion 3 is joined to the bottom lid 1 by the joining component 4, and further the canopy 2
And is joined by the joining component 4 to complete the packaging. Although the connecting parts are shown removable, they can also be preliminarily attached to the bottom lid.

FIG. 2 is a view showing a state in which the packaging device shown in FIG. 1 accommodates a device equipped with a CRT without using the protective sheet 5. The bottom lid is provided with a recess 1A having a shape similar to that of the CRT tube surface so as to receive the CRT tube surface, and a constant space h1 is secured between the central portion of the bottom lid 1 and the floor surface. . Further, the outer peripheral portion of the bottom lid has a convex portion 1B having a substantially semicircular cross section that receives the outer periphery of the housing and cushions the outer casing.
Is provided.

The central portion of the canopy 2 has a concave portion 2A conforming to the shape of the device, and the outer peripheral portion has a convex portion 2B having a substantially semicircular cross section.
Is provided. In addition, a constant space h2 is secured between the recess 2A and the outer shape of the canopy. When this packaging device is dropped in the direction of the bottom plate during transportation, it is buffered by the elasticity of the member of the bottom lid 1, and the portion from the convex portion 1B provided on the outer peripheral portion to the central portion is deformed by the falling energy of the device. Therefore, the buffering effect can be increased.

In addition, when it falls in the lateral direction, the convex portion 1
B and 2B are deformed and serve as a cushioning material. In addition, when it falls in the direction of the top surface, the projection 2
B and the portion continuing from the convex portion 2B to the center portion are deformed and play a cushioning role. In this case, the dimensions of h1 and h2 and the semi-circular dimensions of the convex portions 1B and 2B are the same as the setting of the dimensions of the cushioning material of the general packaging device, based on the “buffering theory”, the mass of the equipment and the guarantee. It is set in consideration of the fall distance, the allowable buffer value of the device, the elasticity of the synthetic resin used for the bottom lid, and the like. Needless to say, other than the synthetic resin used as the member forming the canopy 2 and the bottom cover 1, any member such as a paper member or a laminated member of paper and resin may be used. (Embodiment 2) FIG. 3 is a sectional view of a packaging apparatus according to an embodiment of the present invention.

When the external dimensions of the equipment are smaller than the internal dimensions of the packaging device, the outer circumference of the equipment, the bottom lid, and the projections and bottoms of the outer peripheral portions of each of the canopies and the central portion of the top surface are arranged as shown in FIG. The device is fixed in the packaging device through the auxiliary fixing material 8 described in 1. The auxiliary fixing material in this case is intended to fix the device, and the material used is not particularly limited.
However, if a cushioning material having high elasticity, for example, a molded member made of styrofoam resin or urethane foam rubber is used, it is possible to obtain a further cushioning effect at the same time as fixing when the external dimension of the device is small. (Embodiment 3) FIG. 4 is a sectional view of a packaging apparatus according to an embodiment of the present invention.

The characteristic of this packaging device is that the elasticity of the resin of the bottom lid 1 and the canopy 2 is used to obtain a cushioning effect, but the equipment has a particularly fragile portion, which is damaged by a drop impact,
The device itself may be deformed. Since the container of this packaging device is intended for repeated use, the container itself has a high pressure resistance, and it is not necessary for the contents and auxiliary cushioning materials to receive the gravity of the upper stack during storage and stacking. Therefore, as a method of supplementary cushioning of the fragile portion and prevention of deformation of the equipment itself, a film air-sealed bag-shaped cushioning material 9 made of a resin member, a rubber member, a paper member, a laminated member of paper and resin, or the like is supplemented. It can also be used for, and can provide resource-saving packaging.

[0018]

As described above, the packaging device of the present invention is C
Since the CRT tube surface of the device having the RT is directly held, the strength required for the device housing can be reduced, and the housing can be made thinner and the resin used can be downgraded. At the same time, also in the case structure, it becomes easy to design the shapes of the bosses and the reinforcing ribs of the CRT holding portion, the thickness arrangement thereof, etc., so that the moldability is improved and the degree of freedom in design is obtained.

Further, since the elasticity of the convex portions provided on the bottom lid and the canopy is utilized to play a role of cushioning, it is possible to eliminate the need for a cushioning material, and the fragile portion of the equipment. The device can be protected by using a film-made airtight bag-shaped cushioning material or a very small amount of auxiliary cushioning material. Furthermore, by positioning the center of gravity of the packaging set at the bottom, the bias of the center of gravity in conventional packaging equipment is eliminated, safety is ensured during storage and stacking, and the physical burden and risk to load handling workers are eliminated. can do.

The bottom cover, the canopy, the body, and the connecting parts can be disassembled and collected after the end of transportation, and can be used repeatedly. If auxiliary fixing materials are used as shown in FIG. You can This enables recycling utilization without discarding the packaging member, and thus can greatly contribute to effective utilization of resources and environmental protection.
