Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a packaging box used when transporting and storing a plurality of cathode ray tube panels together.

[Conventional technology]

Conventionally, as shown in FIG. 6, this type of packaging box consists of an outer box 3 made of cardboard or the like and a plurality of inner boxes 1 packed in parallel inside this outer box 3. There is a case in which the top surface is open and a cylindrical triangular support part 7 is provided inside the front edge of both outer plates 6 of the inner box 1 to support both front sides of the cathode ray tube panel A (1983-1993). Publication No. 11047).

[The problem that the idea aims to solve]

By the way, as shown in FIG. 5, the cathode ray tube panel A has a front surface B that bulges forward. This front part B, which swells forward, is the part where the image appears, and is the most important part for the cathode ray tube panel A.

However, in the above-mentioned conventional packaging box, when the cathode ray tube panel A is inserted through the opening on the top surface of the inner box 1, or due to vibrations during transportation, the center of the front part B of the cathode ray tube panel A expands forward. There is a problem in that the front panel 23 of the inner box 1 comes into contact with the front panel 23 of the inner box 1, and the front panel B, which is the most important section of the cathode ray tube panel A, gets scratched.

In order to solve this problem, it is necessary to make the length of the outer plate 6 in the front-rear direction 6 longer than the length in the front-rear direction of the central part of the cathode ray tube panel A, and to It is possible to remove the front plate 23 of the box 1 and open the front of the inner box 1, but opening the front of the inner box 1 has the following disadvantages.

That is, if the front surface of the inner box 1 is opened, the cathode ray tube panel A will be exposed to the front opening of the inner box 1, and the load of the cathode ray tube panel A will be applied to the cylindrical triangle of both outer panels 6. Since it concentrates on the support part 7, there is a risk that the cylindrical triangular support part 7 may be deformed or bent. If the triangular support part 7 is deformed or bent in this way, the cathode ray tube panel A will no longer be held stably, and the cathode ray tube panel A will wobble inside the inner box 1 due to vibrations during transportation. Therefore, when the cathode ray tube panel A is stored in the outer box 3 facing the same direction, the front part B of the cathode ray tube panel A is
The rear panel 4 of the inner box 1 located at the front was contacted and scratched, and when the cathode ray tube panels A were stored in the outer box 3 so as to face each other, the opposing cathode ray tube panels A collided with each other. There is a risk of damage.

In addition, if the front of the inner box 1 is opened, both outer plates 6
The triangular support part 7 can easily open outward or close inward. When the triangular support part 7 opens outward, when the inner box 1 is stored in the outer box 3,
The triangular support part 7 hits the outer box 3, making it difficult to store it, and conversely, when the triangular support part 7 closes inward, it becomes difficult to insert the cathode ray tube panel A into the inner box 1.

Therefore, the problem with this invention is that even if the front side of the inner box 1 is opened, the cylindrical triangular support part 7 is not deformed.
This is intended to prevent scratches on the front surface B of the cathode ray tube panel A by preventing it from bending, opening outward, or closing inward.

[Means to solve the problem]

In order to solve the above problems, this invention makes the length of the outer plate 6 in the front and back direction longer than the length of the center part of the cathode ray tube panel in the front and back direction, opens the front of the inner box 1, and The cushioning material 21 is inserted and filled into the shaped triangular support part 7, and the bottom plate 1 of the inner box 1 is
A locking piece 13 is continuously provided on the front edge of the locking piece 1.
3 is locked to the lower front end of the triangular support portion 7.

[Effect]

By inserting and filling the cushioning material 21 into the cylindrical triangular support part 7, even if the load of the cathode ray tube panel A is concentrated on the cylindrical triangular support part 7, the triangular support part 7 is prevented from deforming or bending. Ru.

In addition, by locking the locking piece 13 connected to the front edge of the bottom plate 12 of the inner box 1 to the lower end of the triangular support part 7, the triangular support part 7 can be opened outward or closed inward. This will be prevented.

This makes it possible to open the front side of the inner box 1 and prevent the front part B of the cathode ray tube panel A from coming into contact with the inner box 1.

〔Example〕

Figures 1 to 4 show an embodiment of this invention, and this packaging box for cathode ray tube panels is made of thick paper such as cardboard, and has an open top and front surface for storing one cathode ray tube panel. A plurality of inner boxes 1 are connected to each other via a rectangular insole plate 2.
It consists of a bottomed outer box 3 in which items are arranged in a row and packed. The inner box 1 is assembled from a single board (see FIG. 2) cut from cardboard. This board is
An outer plate 6 is connected to the left and right edges of the rectangular back plate 4 via fold lines 5, and a cylindrical triangular support part 7 is provided at the front end of the outer plate 6 together with a part of the outer plate 6.
(See Figure 3) Front plate 8 and inner plate 9 forming
are successively connected, and an inner plate 10 that overlaps the outer plate 6 is connected to the inner plate 9, and a bottom plate 12 having approximately the same width as the outer plate 6 is connected to the lower edge of the back plate 4 via a fold line 11. The locking pieces 13 are successively connected to each other, and the folding pieces 16 are connected to the lower edge of the outer plate 6. The length of the outer plate 6 in the front-rear direction is longer than the length of the central portion of the cathode ray tube panel in the front-rear direction.

Further, the substrate is provided with a notch 17 that engages with a locking piece 13 that stands up at the lower end of the boundary between the front plate 8 and the inner surface plate 9, and the back plate 4 has a pair of small notches 17 along the fold lines 15 on both side edges. A slit 14 is provided, a semicircular notch 15 is provided at the center of the upper edge for extracting the panel, and the inner surface plate 9 has small connecting portions 18 at both upper and lower ends.
A relatively large trapezoidal window 19 is provided which becomes wider toward the inner plate 10 while leaving the inner plate 10, and the inner plate 10 has a locking piece 2 on its edge that fits into the slit 14 of the back plate 4.
0 is provided protrudingly.

In the inner box assembled by bending this board, a triangular prism-shaped cushioning material 21 made of foamed polystyrene is inserted into the triangular support part 7, and this is exposed from the window 19, and the housed cathode ray tube panel The front left and right vertical edges C are in contact with and protected by the cushioning material 21 made of expanded polystyrene. Furthermore, by opening the front surface of the inner box 1, a gap 1 is created between the front surface of the cathode ray tube panel and the adjacent inner box, as shown in FIG.

When assembling the inner box 1 from the board, as shown in FIG. The face plate 8 and the inner surface plate 9 are bent inward to form the triangular support part 7, and the slit 1 is formed.
When the locking piece 20 is inserted into the triangular support part 4, the triangular support part 7 becomes stable and at the same time the outer plate 6 and the inner plate 10 overlap. Furthermore, when the locking piece 13 is bent and inserted into the notch 17 at the lower end of the triangular support part 7, the elasticity of the material of the triangular support part 7 prevents it from returning. A triangular prism-shaped cushioning material 21 is inserted and filled into the triangular support portion 7 of the inner box 1.

According to this cathode ray tube panel packaging box, when the cathode ray tube panel A is inserted into the inner box 1 with the front part B facing the triangular support part 7, as shown in FIG. Both vertical edges C of the bulging front part B of the cathode ray tube panel A come into contact with the panel 21, and the panel is not damaged due to the flexibility of the foamed polystyrene cushioning material 21. Note that the upper and lower connecting portions 18 of the inner surface plate 9 of the triangular support portion 7 are connected to the cathode ray tube panel A.
It corresponds to the corner part D, that is, a slightly recessed part, and does not come into direct contact with the cathode ray tube panel A.

[Effect of idea]

As described above, according to this invention, by opening the front surface of the inner box 1, the cathode ray tube panel A
Since contact between the front part B of the cathode ray tube panel A and the inner box 1 can be prevented, there is an effect that the front part B, which is the most important part for the cathode ray tube panel A, will not be scratched.

Furthermore, since the front of the inner box 1 is opened, there is also the effect that the amount of packaging materials used can be reduced.
