Description

Funnel Packaging for Cathode Ray Tubes {pack for CRT funnel}

The present invention relates to a funnel packaging material for a cathode ray tube, and more particularly, to a funnel packaging material for a cathode ray tube, which is simple to assemble and dismantle the packaging material, thereby reducing manufacturing costs and increasing its support rigidity.

In general, the cathode ray tube (CRT) is formed of a glass panel (Panel), the fluorescent material is coated on the inner surface, and a funnel (Funnel) is mounted on the electron gun. Panels and funnels are typically manufactured separately in glassware factories and then transferred to other producers or processes that manufacture cathode ray tubes and assembled with other components (shadow masks, guns, frames, etc.).

Such cathode ray tube panels and funnels are relatively heavy and easily break when they do not require handling. Therefore, the glass producers are supplied with packaging materials of various specifications produced separately so that the glass is not damaged in the process of supplying to the user.

The conventional funnel packaging material is stacked in multiple layers on the pallet 60, as shown in Figs. 1 and 2, with a plurality of (four) rectangular enclosures 50 arranged in each layer. Each of the enclosures 50 has a plurality (three) of funnels 30 are placed with the neck 31 facing upwards, while a plurality of (two) funnels 30 are between the funnels 30 31) is placed downwards.

At this time, the interliner 40 is inserted to prevent the funnel 30 from being damaged due to surface damage such as scratches of adjacent funnels 30 and impact of shaking of the vehicle during transportation, and a neck which is relatively susceptible to impact. In order to protect the 31, a separate branch pipe 20 is fitted to the outer circumferential surface of the neck 31.

Then, each layer is completed by fitting the cover 10 in which the necks 31 and the branch pipes 20 through holes 11 are formed. The corner portion of the cover 10 is bent downward and then bent upwards again by twice the width of the downward width (expanded in FIG. 2) and bonded with an adhesive, and the lower and upper layers of the upper enclosure 50 and the lower enclosure 50 ) To support lateral forces at the top.

The plurality of holes (3) of the plurality of holes 11 extending in the longitudinal direction of the cover 10 hold the funnel 30 with the neck 31 facing upward, and the remaining plurality (two) Holes 11 are for holding the funnel 30 in which the neck 31 faces downward among the funnels 30 that are deposited in the second layer.

However, such a conventional packaging material structure has a weak supporting rigidity of the cover 10 surrounding the plurality of (4) enclosures 50, so that the enclosure 50 is severely shaken during product transfer, causing a lot of breakage of the adhesive portion of the cover 10. do. That is, there is a problem in that the funnel 30 due to the breakage of the enclosure is damaged by supporting a large load on the side wall of the enclosure 50 composed of one layer.

In addition, as the packaging parts of the conventional funnel packaging materials are various and the packaging material assembly process is complicated, the packaging process is performed after a separate decontamination process, resulting in an increase in production cost due to reduced work efficiency and packaging cost due to packaging material damage. It is causing an increase.

Accordingly, an object of the present invention is to reduce the packaging cost by reducing the damage to the packaging material, the type of components constituting the packaging material is simple and easy to assemble, the funnel for cathode ray tube to reduce the manufacturing cost according to the improved productivity To provide a packaging.

In addition, there is no need for a separate decontamination process, so it is not necessary to have a large storage area for storing the funnel packaging material, and to provide a funnel packaging material for cathode ray tube that can reduce the packaging material management cost and transportation cost and increase its rigidity. .
