Each of the cushioning materials is formed by molding a foamed resin member into a predetermined shape, or a paper cushioning material such as corrugated board or pulp mold.

[0003]

[Problems to be solved by the device]

 However, the CRT occupies 1/2 to 2/3 the weight of the television receiver, and the housing containing this CRT is extremely strong against the impact such as a drop when handling a transportation load. Need. Therefore, it is necessary to use a large amount of a member having a large cushioning effect as a cushioning material for protecting the casing in order to prevent the casing from being damaged during a drop impact. Furthermore, the center of gravity of devices equipped with a CRT such as a television receiver is biased forward. Stacking pre-packaged sets with uneven center of gravity is extremely unstable and may cause the load to collapse or fall. In addition, the operator is forced to have an unreasonable force or posture when handling the load, which may cause a tight waist or reduce the work efficiency, which is not preferable. In view of the above problems, the present invention provides a packaging device that satisfies the requirements of reducing the strength and thinning of the housing, reducing the amount of cushioning material, and ensuring safety during transportation and storage.

[0004]

[Means for Solving the Problems]

 The packaging device of the present invention has a structure in which the CRT tube surface, which is heavy and causes eccentricity of the center of gravity, is arranged downward, and the tube surface of the CRT and the side surface of the housing are received and fixed by a cushioning material.

[0005]

[Action]

 With the above configuration, the center of gravity of the packaging set is lowered in a stable direction and eccentricity is eliminated. In addition, in the case of a drop impact, the CRT tube surface, which is the heaviest item of the equipment, is directly received by the cushioning material, so that the potential energy of the CRT is directly absorbed by the cushioning material when it falls. Therefore, the drop impact strength required for the housing is greatly reduced, and the housing can be made thinner. As a result, it is possible to reduce the amount of use of the casing constituent material and the cushioning material, and it is possible to reduce the cost by simplifying the constitutional shape of the cushioning material.

 An embodiment of the present invention will be described below 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 device according to an embodiment of the present invention. The packaging device 10 includes a rectangular corrugated box 3 configured to fold and seal a bottom surface and an upper surface, a rectangular flat bottom main cushioning material 4A for supporting a CRT tube surface 2 inserted downward, and a housing. It is composed of a bottom surface auxiliary cushioning material 4B that supports the four corner portions of 1 and a top surface auxiliary cushioning material 5 that also supports the other four corner portions of the housing 1. The shapes of the bottom surface auxiliary cushioning material 4B and the top surface auxiliary cushioning material 5 are such that one corner of the hexahedron is cut out in correspondence with each corner shape of the housing 1. As the packaging procedure, the CRT tube surface 2 of the television receiver is inserted downward into the cardboard box 3. The cardboard box 3 has a flap (cut-and-raised portion) 6 formed at the center of the bottom surface, and the CRT tube surface 2 is supported by the main cushioning material 4A which is placed in the flap 6 and whose position is regulated. Bottom auxiliary cushioning materials 4B arranged at the four corners of the bottom surface and supporting the corners of the housing 1 prevent the equipment from moving in the front-rear, left-right direction and cushion the edges from falling and falling from the side. Further, the upper surface auxiliary cushioning material 5 which supports the other corner portion of the housing 1 also plays a role of preventing movement of the device in the front, rear, left and right directions and in the upper surface direction, and cushioning when dropped. The bottom main cushioning member 4A is configured to always reliably support the central portion of the CRT tube surface by regulating the position by the cut-and-raised portion 6 provided on the inner flap of the bottom of the cardboard box 3.

The main cushioning material 4A has a rectangular flat plate shape and a simple shape. It is not limited to a general foamed resin member molded, but may be made of corrugated cardboard (not shown) that uses a honeycomb shape or a substitute thereof, and has the advantage that the material and processing method are not limited. There is. Further, the bottom auxiliary cushioning member 4B and the upper surface supplementary cushioning member 5 do not have to directly receive the weight of the television receiver, but serve for cushioning the position regulation of the housing housing the CRT and side drop with low probability. Therefore, it has the advantages that it can be made smaller and lighter than before, and the selection range of materials and shapes is expanded. That is, in addition to the foamed resin molded material having the shape shown in FIG. 1, the corners and side surfaces of the housing 1 are sandwiched and fixed by four film air-sealed bag-shaped auxiliary cushioning materials 4C as shown in FIG. It may be configured. Further, as shown in FIG. 3, only the vertical edges of the housing 1 may be sandwiched and fixed by the four L-shaped auxiliary cushioning materials 4D. (Embodiment 2) FIG. 4 and FIG. 5 are an exploded perspective view and a side sectional view of a packaging apparatus according to an embodiment of the present invention. The packaging device 20 includes a rectangular corrugated box 43 configured to fold and seal a bottom surface and an upper surface, and two end portions of the CRT tube surface 2 inserted downward and two continuous corner portions. It consists of bottom cushioning material 7A. The bottom cushioning material 7A is formed by molding, for example, a foamed resin member or the like. It has a substantially L-shaped cross section, a tongue-shaped CRT receiving surface 7B, and an escape recess 7C, and one edge is cut out corresponding to the side shape of the housing 1. In this case, the bottom cushion 7A eliminates the bottom main cushion 4A described in FIG. 1 and omits the top supplementary cushion 5 to further reduce the amount of cushion used and reduce the cost. . As a packing procedure, bottom cushioning materials 7A may be arranged in advance at the bottom corners of the corrugated cardboard box 43 and inserted with the CRT tube surface 2 of the television receiver facing downward.

[Effect of device]

 As described above, the packaging device of the present invention is configured not to hold the CRT tube surface through the housing. Therefore, the strength required for the entire case is reduced, and the case can be made thinner and the resin used can be downgraded. Also, in the case structure, the boss of the CRT holding part, the shape and thickness arrangement of the reinforcing ribs, etc. are simple and easy, improving moldability, improving mold strength, and increasing design flexibility. Therefore, quality problems such as housing damage can be resolved. Furthermore, the amount of cushioning material used can be greatly reduced and the amount of waste material can be reduced, which greatly contributes to environmental conservation. Furthermore, it contributes to the reduction of storage and transportation costs by reducing the packaging volume. Furthermore, by positioning the center of gravity of the packaging set downward and eliminating the eccentricity, it is possible to ensure safety during storage and stacking, and to eliminate the physical burden and danger to the load handling worker. Further, due to the structure of the CRT, the shadow mask holding portion, the electron gun portion, and the like have a higher impact resistance when the CRT tube surface is directed downward, and the occurrence of defects during transportation or dropping is reduced.
