Description

[Detailed Description of the Invention] The present invention relates to a partition plate that holds a cathode ray tube panel section.

'The cathode ray tube panel must be protected from minute scratches on the mirror surface of the panel during packaging and transportation.

When packaging cathode ray tube panels, attention must be paid to dust present in the packaging container, cushioning properties of the packaging container, and tight packaging.

Furthermore, for mass transportation and storage of cathode ray tube panels, it is desired that the packaging be easy to package, assemble, and clean, and that the cathode ray tube panels can be easily put in and taken out.

It goes without saying that the present invention was devised to achieve this purpose, but in addition to this purpose, another major purpose of the present invention is to reuse packaging materials as they are.

In other words, some conventional packaging methods include an inner box for storing the cathode ray tube panel and an outer box into which multiple inner boxes can be loaded, facilitating mass transportation and storage. The empty inner box after transportation and storage is either discarded or stored or transported as an empty box until it is reused, which is wasteful and inconvenient.

In addition, in this conventional packaging method, paper, cotton, or other filler was stuffed into the gap between the cathode ray tube panel of the inner box and the inside of the box to provide cushioning and tight packaging for the packaging container. The work was time-consuming, and it was also not easy to remove the cathode ray tube panel.

In addition, it was not possible to reuse the filler.

This is because in order to reuse it, it is necessary to remove the dust that has adhered to the inside of the inner box, and also to remove the dust that has adhered to the filling material, but cleaning this filling material is difficult. This is because replenishing new filler material will reduce costs.

The present invention has been made to solve all of these problems.

Here, an embodiment of the present invention will be described in detail with reference to the attached drawings. As shown in FIGS. 4 and 5, a flexible thin paper 2 with small wrinkles 3 with a crepe rate of about 35% is made using new pulp as a material. The interior protection partition plate is formed by the plate material A which is made and pasted on one side of the corrugated paperboard 1, and the interior protection partition plate consists of the main plate 4 and the second
It is constructed by a combination of a pair of upper and lower plates 5 and 6 shown in FIGS.

The main plate 4 has a rectangular shape as shown in FIG. 1a, and has a plurality of vertically parallel straight folds B.

When folded along this fold B with the thin paper side inside, the second
As shown in the figure, a rectangular tube with an open top and bottom is molded, with the inner surfaces on the front, back, left, and right west sides lined with thin paper.

The folds B are arranged at intervals such that when the cathode ray tube panel P is housed in the rectangular tube, the cathode ray tube panel comes into contact with the thin paper on the inner surface of the four sides.

In Figure 1a, the main plate 4 has two notches on its upper side, which are used to insert and remove the cathode ray tube panel when the main plate 4 is formed into a rectangular tube, as shown in Figures 2 and 3. It was established to facilitate the

A plurality of rectangular tubes formed in this way are arranged side by side in the box 7 to form a partition as shown in Fig. 6, but since the top and bottom are open, plates are used to protect the top and bottom of the cathode ray tube panel. The upper and lower open parts of a plurality of rectangular tubes arranged side by side are closed with upper plates 5 and lower plates 6 made of A, each with the thin paper side facing inside.

Therefore, the upper and lower plates 5 and 6 are flat plates large enough to close the plurality of openings, and are constructed so that the upper and lower parts of the cathode ray tube panel abut against the thin paper.

As a result, a partition is formed within the box 7 to protect the cathode ray tube panel.

The reason why we made thin paper with a crepe rate of 35% and attached it to corrugated paper is as follows.

In other words, if the crepe rate of the pasted thin paper is too high, the difference in height of the wrinkles will be excessive, and the thin paper will retain coarse dust that has a negative effect on the mirror surface, and if the crepe rate is too low, the flexibility will be reduced. Along with this, it also stops absorbing minute dust.

Therefore, if you apply a paper with at least 35% as a standard, the crepe rate of the attached thin paper will vary slightly, but it will fall within the crepe rate range that has a cushioning effect due to its flexibility and an ability to absorb minute dust. This is because we have found that it is maintained.

Thus, in the present invention, since the thin paper 2 is made from new pulp, there is no risk of scratches or stains on the mirror surface, unlike recycled white paper that contains sand, ink, and other impurities, and it does not contain chemical fibers. However, there is no risk of clouding or the like occurring on the mirror surface and reducing the functionality of the cathode ray tube panel.

The thin paper 2 attached to the corrugated paper is a thin paper with a crepe rate of 35%, so the crepe rate after pasting is around 35%, and the minute dust that adheres to the mirror surface is in the small wrinkles. It absorbs dust and prevents dust from coming into direct contact with the mirror surface, eliminating scratches on the mirror surface.Furthermore, the flexibility of the small wrinkles, combined with the elasticity of the corrugated paper, cushions external shocks and prevents damage to the cathode ray tube panel. is prevented.

The partition inside the box 7 is formed by the simple operation of bending the main plate 4 and arranging it side by side, and placing the upper and lower plates 5 and 6 above and below it.The CRT panel is thus tightly packed, and the plate material is Since A is made of corrugated paper with thin paper pasted on one side, it eliminates the need for additional filling material, making the packaging process easier.

In addition, since there is no other filler and the only interior of the box 7 is a partition, it is easy to take out the cathode ray tube panel.

On the other hand, after removing the cathode ray tube panel section, the upper and lower plates 5
, 6 are originally flat plates, and the main plate 4 can be immediately unfolded from the rectangular cylinder and returned to the flat plate in the state shown in FIG. 1a, making it easy to store and transport.

Also, since it is a flat plate, it does not attract dirt or dust during storage or transportation, unlike an empty box.

Although cleaning work is required for reuse, the cleaning work is extremely easy in the present invention because a flat plate is cleaned rather than a box-shaped object.

In addition, when trying to reuse packaging materials in conventional packaging methods, it is necessary to clean both the inner box and the filler, and cleaning of the filler such as tissue paper, which was kept separately after use, is required. However, in the present invention, since the thin paper is attached to the cardboard, only the cleaning of the plate material A is required, and since the flat plate is cleaned, cleaning of the thin paper surface is also easy. Minute dust attached to thin paper can be removed by a simple operation such as applying vibration to a flat plate with the paper side facing down.

Thus, the present invention protects the cathode ray tube panel.
A partition plate that is suitable exclusively for shipping boxes will be provided.
