Description

[Detailed Description of the Invention] This invention relates to a package for a cathode ray tube, and is designed to allow the cathode ray tube to be transported and stored in good condition without damage.

Conventionally, backing cases are used to transport and store finished cathode ray tube products, but the shape of cathode ray tubes makes it difficult to package them, so corrugated paper, etc. is assembled inside the backing case to prevent them from shaking as much as possible. It was packaged as such.

In addition, cushioning material such as sponge was applied to the face plate of the cathode ray tube, which was the image side, to protect it.

However, the above-mentioned packaging is very troublesome, and because it is difficult to follow the cathode ray tube and lacks stability, the cathode ray tube has the disadvantage that it is easily damaged by shaking due to vibrations during transportation or other handling.

Therefore, in this invention, the above-mentioned conventional drawbacks and inconveniences are solved to obtain a packaging body suitable for CRT packaging, which is composed of a substantially flat plate of synthetic resin with a thickness equal to the height of the CRT. It consists of packaging bodies formed from shaped foam bodies that are symmetrically assembled into upper and lower sets, each packaging body having a plurality of four parts capable of accommodating at least the main body of a cathode ray tube, and the plurality of recesses having at least four parts. 1
It consists of a set of coarse rows arranged in a staggered manner, and the concave portions in the staggered positions are formed back to back with each other, and there are reinforcing protrusions integrated into each other at the common left and right positions in the center of the back. The reinforcing protrusions abut each other from above and below when the cathode ray tube is sandwiched between the upper and lower packaging bodies, and the other parts form gaps between the packaging bodies.

Next, embodiments of this invention will be illustrated below with reference to the drawings.

Reference numeral 1 denotes a cathode ray tube packaging body made entirely of synthetic resin foam, such as expanded polystyrene, and formed into a substantially flat plate shape with a thickness equal to the height of the cathode ray tube. The upper and lower parts are combined into a set so that the cathode ray tube 10 is sandwiched between them.

Reference numeral 2 denotes a plurality of recesses formed in the package 1, which are curved so that at least the main body 11 of the cathode ray tube 10 can be fitted therein, and are composed of at least one set of coarse rows arranged in a staggered manner. , the staggered recesses 2 and 2 are formed back to back.

In addition, FIG. 1 shows an example in which the above-mentioned coarse rows are arranged into two sets of packages each having one set, and FIG. Although the case in which the number of recesses 2 is four in each case is shown, it can be implemented with various numbers (however, a plurality of recesses).

Reference numeral 3 denotes a reinforcing protrusion for abutment provided at a common portion on the left and right from the back center of the back-to-back recesses 2, 2, so that they can be integrated and shared between the staggered positions.

When the cathode ray tube 10 is sandwiched between the upper and lower packages 1, 1, the reinforcing protrusions 3 abut against each other from above and below, so that a gap can be formed between the other parts of the packages 1, 1. There is.

Note that 4 and 4' in the figure are holes formed in the bottom surface of the recess 2, and the main body 11 of the cathode ray tube 10 accommodated in the recess 2.
This is to create a space between the cathode ray tube and the main body, and is suitable for escaping the air that is pressed when the cathode ray tube is stored.In addition, when the cathode ray tube is stored in the outer box 20 such as a backing case, external shocks can pass through the package 1 to the main body. 11 is removed by the space and is reduced, further improving the buffering effect.

Reference numeral 5 denotes a surplus portion provided so that the entire shape of the package 1 is square, but it can also be formed separately.

The synthetic resin foam forming the above package 1 includes:
In addition to foamed polystyrene, polyolefin resins such as ethylene homopolymer, ethylene copolymer such as ethylene-vinyl acetate, propylene homopolymer, or foamed particles in which at least a portion of polyolefin resin and polystyrene resin are grafted are used. Heat-expanded foam For example, foamed particles that are graft-bonded to polyethylene by absorbing styrene monomer into the core using polyethylene particles and polymerizing the styrene monomer within the core, and then adding a foaming agent to the foam are heated and expanded. A foam made by fusing the above-mentioned particles to each other is also suitable because it has a small degree of creep deformation due to loading and has high impact absorption properties.

Regarding the use of the cathode ray tube packaging body according to this invention described above, two symmetrical upper and lower pieces are used as a set, and the recesses 2 and 2 formed in each packaging body 1 are vertically opposed to each other. At least the main body part 11 of the cathode ray tube 10 is fitted and housed in the recesses 2, 2 so that the recesses 2, 2 are aligned.
It is packaged with the cathode ray tube 10 sandwiched between them, and the reinforcing protrusions 3, 3 of each package 1 abut each other from below, and the other parts leave a gap between the packages 1, 1. Since it can be formed, it reduces the direct transmission of external shock to the cathode ray tube 10, improves the cushioning properties, and improves the grip of the cathode ray tube.
The storage stability in an outer box such as a backing case is also improved.

Further, the cathode ray tube can be visually recognized from the outside through the above-mentioned gap, which is convenient for inspection, etc.

Moreover, not only the above-mentioned gap when sandwiched, but also the symmetrical pair of upper and lower packaging bodies have a substantially flat plate shape with a thickness equal to or less than the thickness of a cathode ray tube, which contributes to even lighter packaging.

Further, in this invention, the plurality of recesses 2.2 of each package 1 are made up of at least one set of coarse rows arranged in a staggered manner, and the recesses 2.2 in staggered positions are formed so as to be back to back to each other. Therefore, in any case where a set of multiple staggered coarse rows is used in combination, or when a plurality of staggered coarse rows are used in each package, a small space can be used effectively. This also helps in reducing the packaging space required for storage in the outer box 20 such as a backing case.

The package of this invention can be used not only for finished cathode ray tubes, but also for packaging funnel-shaped material bulbs used in the manufacture of cathode ray tubes, with almost no difference from the finished product.

By using the cathode ray tube packaging according to this invention as described above, the packaging becomes suitable for preventing the cathode ray tube from shaking during transportation and other handling, and the cushioning characteristic of the synthetic resin foam can be used. Coupled with its properties, it can exhibit excellent practical effects such as being suitable for preventing damage to cathode ray tubes to be packaged.
