Description

[Detailed description of the invention] Industrial application field This invention relates to a packaging structure for cathode ray tubes in which cathode ray tubes are packed in a packaging box.

BACKGROUND OF THE INVENTION Cathode ray tubes are usually manufactured in specialized glass factories and shipped to television assembly factories in packaging boxes.
In this case, the packaging structure for cathode ray tubes is such that a foamed synthetic resin buffer board with multiple recesses of the same shape on the front and back sides into which half of the cathode ray tubes fit is interposed between the cathode ray tubes. They were stacked and stored.

Problems that the invention aims to solve: However, in this conventional packaging structure for cathode ray tubes, the foamed synthetic resin buffer plate has recesses of the same shape and is compatible with only one type of cathode ray tube, which increases the number of types of cathode ray tubes. As a result, it is necessary to prepare many types of tubes in various shapes, and it is necessary to keep a large number of types in stock.In addition, there are problems when packaging, such as not being able to fit two types of cathode ray tubes in a packaging box. Ta.

Means for Solving the Problems In this invention, in order to solve the above-mentioned problems, the foamed synthetic resin buffer plate has recesses of different shapes corresponding to different types of cathode ray tubes on the front and back sides of the foamed synthetic resin buffer plate. A plurality of the foamed synthetic resin buffer plates are provided at different positions and are interposed between the cathode ray tubes, and a recess on the front or back surface corresponding to the shape of the cathode ray tube that comes into contact is fitted into the cathode ray tube.

Function According to this invention, the buffer plate used has recesses corresponding to two different shapes of cathode ray tubes on the front and back sides, and these recesses are different from each other on the front and back sides. Since the wall is thin enough to effectively utilize the thick part of the board, it does not become bulky even if multiple tubes are placed between the upper and lower cathode ray tubes, and the front and back surfaces can be used selectively. Therefore, it can be applied to two different types of cathode ray tubes, and different types of cathode ray tubes can be packed simultaneously in one packaging box.

Embodiment An embodiment of this invention will be described based on the accompanying drawings. In an embodiment of this invention, as shown in FIG. 1, a relatively thin rectangular foamed polystyrene material is provided with recesses 2 and 3 of different shapes corresponding to different types of cathode ray tubes on the front and back surfaces, which are staggered from each other. A packaging box is created by interposing a plurality of foamed synthetic resin buffer plates 1 such as plates between the cathode ray tubes, and fitting the recesses on the front or back surface to the cathode ray tubes corresponding to the two types of cathode ray tubes A and B to be packaged. The cathode ray tubes A and B are stacked in C, and the cathode ray tubes A and B are alternately partitioned and stored.

Furthermore, it is clear that only cathode ray tubes of the same type, either A or B, can be stored in the packaging box C.

The foamed synthetic resin buffer plate 1 is shown in FIGS. 2 and 3.
As shown in the figure, a plurality of planar substantially semicircular recesses 2 into which a part of the greatly bulging fluorescent surface of a cathode ray tube A (see Fig. 1) is fitted are arranged in regular rows with a half-pitch shift between adjacent rows. Different types of cathode ray tubes B (first
A plurality of planar substantially semicircular recesses 3 having approximately the same size and different shapes as the recess 2 into which a part of the greatly bulging fluorescent surface portion of the recess 2 (see figure) is fitted are provided similar to the surface and with the recess 2 on the surface. They are arranged in four rows at different positions so that they do not overlap.

The recesses 2 and 3 are formed in a spherical shape such that the linear portion where the front surface of the fluorescent surface of the cathode ray tube A hits is deep and becomes shallower toward the arcuate edge. Next, we will explain these recesses in detail.
As shown in FIG. 4, the recesses 2 on the surface include three pairs of equally spaced recesses 2a provided at both ends of the plate surface facing backwards, and recesses 2a provided in the center alternating with the recesses 2a. and two pairs of recesses 2b in opposite directions, and a cathode ray tube A is fitted and supported in a parallel manner so that the electron gun part is brought into contact with the recess 2a, and the fluorescent surface part is brought into contact with the recess 2b. can do.

As shown in FIG. 5, the recess 3 on the back surface is
Three pairs of recesses 3a provided in the center, and two pairs of recesses provided in opposite directions alternately with the recesses 3a at both ends.
It consists of a pair of recesses 3b, and a different type of cathode ray tube B can be fitted and supported in parallel with the recess 3a so that the fluorescent surface part is butted against it, and conversely so that the electron gun part is butted against the recess 3b. can.

The buffer plate 1 is provided at different positions so that the recesses 2 on the front surface and the recesses 3 on the back surface do not overlap, but since the plate thickness is relatively thin, the bottoms of both recesses Although the through holes 4 are partially overlapped, this does not pose any problem in terms of strength, and since the two sheets are stacked one on top of the other and interposed between the cathode ray tubes, they have sufficient cushioning properties.

The packaging structure of the cathode ray tube of this invention consists of two buffer plates 1 with their surfaces facing each other, as shown in Figure 1.
The fluorescent surface part is fitted into the recess 2 between them to hold and support the cathode ray tube A, and the fluorescent surface part is fitted into the recess 3 between them using two separate buffer plates 1 whose back surfaces face each other. By holding and supporting different types of cathode ray tubes B, two types of cathode ray tubes A and B having different shapes can be packed in multiple stages in one packaging box C.

It is also possible to box and package only the cathode ray tube A with only the front side facing each other, or to box and package only the cathode ray tube B with only the back side facing each other.

Effects As described above, the packaging structure of the cathode ray tube according to this invention has a concave part on the front surface and a concave part on the back surface which have different shapes but approximately the same size, and are made of foamed synthetic resin provided at different positions. It uses a buffer plate, and the buffer plate can be made thin, and by interposing a plurality of buffer plates between the cathode ray tubes and selectively using the front and back sides, it can accommodate two types of cathode ray tubes. This reduces the number of types of buffer plates by half, which is advantageous in terms of management.Also, since different types of items can be packed in the same packaging box, it is convenient for transporting odd quantities of items, and the cost of molds used for molding can be reduced. This has many effects, such as reducing packaging costs.
