Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a cushioning material for packing cathode ray tubes used for packaging a plurality of cathode ray tubes arranged on the same plane in a stacked manner.

[Background of the invention]

When transporting cathode ray tubes, a plurality of cathode ray tubes arranged on the same plane are sandwiched from above and below by cushioning materials such as foamed polystyrene moldings, and the tubes are packaged in a stacked manner.

The buffer material includes a lower buffer material disposed at the bottom, an intermediate buffer material disposed between each layer, and an upper buffer material disposed at the top. A lower fitting part is formed on the upper surface of the lower cushioning material, into which a part of the lower part of a plurality of cathode ray tubes is fitted. The intermediate cushioning material has an upper fitting part formed on a lower surface thereof into which a part of the upper part of a plurality of cathode ray tubes fits,
A lower fitting part into which parts of the lower parts of the plurality of cathode ray tubes are fitted is formed symmetrically with the upper fitting part on the upper surface.

An upper fitting part into which a part of the upper part of a plurality of cathode ray tubes is fitted is formed on the lower surface of the upper cushioning material.

By the way, as mentioned above, a slight increase or decrease in the height of a stacked cathode ray tube package greatly affects the transportation efficiency, so in order to reduce the stacking height as much as possible, use as much cushioning material as possible for packaging. It needs to be thin.

On the other hand, a cathode ray tube generally has a lug plate a protruding from the main body of the cathode ray tube 1, as shown in FIG. As mentioned above, the intermediate cushioning material has vertically symmetrical fitting portions formed on the upper and lower surfaces, so that the lug plate of the CRT placed on the upper surface and the lug plate of the CRT placed on the lower surface are connected to each other. In order to avoid impact, the intermediate cushioning material had to be thicker than its original cushioning function, which was disadvantageous in terms of transportation efficiency and raw materials.

[Purpose of the invention]

An object of the present invention is to provide a cushioning material for packaging cathode ray tubes that can improve transportation efficiency and save raw materials.

[Summary of the invention]

The present invention is characterized in that the upper fitting part and the lower fitting part on the upper and lower surfaces of the intermediate cushioning material are formed by being displaced. , will be explained with reference to FIG. The illustrated embodiment shows a case where four cathode ray tubes are packed in two layers. A lower fitting part 2a is formed on the upper surface of the lower cushioning material 2, into which a part of the lower part of the four cathode ray tubes IA, , IA2.1A3, and IA4 is fitted. The intermediate buffer material 3 has the four cathode ray tubes lΔ1 to I on its lower surface.
An upper fitting part 3a into which a part of the upper part of A4 fits, and a lower fitting part 3b into which a part of the lower part of four cathode ray tubes IB, 1B3, and IB4 fit are formed on the upper surface. There is.

Here, the upper fitting part 3a and the lower fitting part 3b are the lug plates (projections) l of the cathode ray tubes IA to IA4 on the lower surface side.
The lug plates 1a of the cathode ray tubes IB, . On the lower surface of the upper cushioning material 4, there is an upper fitting part 4a into which a part of the upper part of the four cathode ray tubes IB to IB4 fits.
has been formed.

In this way, upper fitting portions 3 are provided on the upper and lower surfaces of the intermediate cushioning material 3.
Since a and the lower fitting parts 3 and b are formed to be displaced, direct contact between the upper and lower lug plates 1a can be avoided even if the intermediate cushioning material 3 is made thin.

〔Effect of the invention〕

According to the present invention, since the intermediate cushioning material can be formed thinly, transportation efficiency can be improved and raw materials can be saved.
