The present invention relates to a box accommodating a plurality of liquid crystal display devices in a space using the main body 10 and the cover 20, and the step 19 to be engaged with the mating surface of the main body 10 and the cover 20. 29 is formed. The step 19 of the main body 10 is protruding, and the step 29 of the cover 20 is concave. Steps 19 and 29 allow the cover 20 to be opened and closed manually and have dimensions that are not too loose. An inclined surface 29a (see FIG. 3) is formed at the edge portion of the cover 29 in the stepped portion 29 to prevent the stepped pieces 19 and 29 from being engaged by the opening and closing and to be easily opened and closed.

Is it omitted in the city? In order to improve the engagement of the step 19 and 29, a plurality of protrusions may be added to one contact surface, and a plurality of grooves may be added to the other contact surface to be engaged with each other.

In addition, according to the present invention, the corrugated groove 16 has a corrugated groove 16 for supporting the liquid crystal display device on the inner surface of the main body 10. The corrugated groove 16 has a wide inlet and narrows inward to allow the liquid crystal display device of A to be inserted. It is a complete symmetrical structure in which the pitch, depth, and length of the corrugated grooves 16 are matched on opposing inner surfaces. The inlet of the corrugation groove 16 is formed in a round to prevent damage.

In addition to the above-described corrugated grooves 16, the tooth grooves 17 and 27 may be further provided in the main body 10 and the cover 20 so as to support the upper and lower ends of the liquid crystal display device. As shown in FIG. 2, the toothed grooves 17 of the main body 10 are formed by separating the two rows, and the recessed grooves are arranged as shown by the reference numeral 18 therebetween. Concave groove 18 is used to save the material, but the size to improve the fluidity and cooling properties during molding. As shown in FIG. 3, since the material thickness is thinner than that of the main body 10, the tooth grooves 27 are formed in a line on the center line without leaving the recessed grooves 18. The upper and lower tooth grooves 17 and 27 coincide with each other in pitch and depth, and also coincide with the above-described corrugated grooves 16 exactly.

In this case, the tooth grooves 17 and 27 further include inclined surfaces 17a and 27a on at least one side thereof to facilitate entry and exit of the liquid crystal display. In FIGS. 2 and 3, the tooth groove 17 of the main body 10 is formed on one side, and the tooth groove 27 of the cover 20 is formed on both sides. The inclined surfaces 17a and 27a make it easy to enter and exit the liquid crystal display device and prevent damage by being impacted at angled corners when entering and exiting.

In addition, according to the present invention, the band grooves 11 and 21 are provided on the outer circumferential surfaces of the main body 10 and the cover 20 to accommodate the band for binding. After the main body 10 and the cover 20 are integrally engaged, a band (not shown) is engaged at at least two points, and the band grooves 11 and 21 are used. The band grooves 11 and 21 are formed on three surfaces to a depth such that the band is not separated, and is omitted on the upper surface of the cover 20 so as to easily hold the band by hand from the upper side.

Concave grooves such as 13 and 23 formed on the outer surface of the main body 10 and the cover 20, as described above, saves the material and ensures uniform flow during molding and uniform drying during cooling. In particular, the concave groove 13 of the main body 10 can also be used as a handle when carrying a box in the state in which the band is bound.

On the other hand, the outer surface of the main body 10 and the cover 20 in Figure 1 is an appropriate gradient for demoulding, so the depth of the concave grooves 13, 23 is also variable. And the circular grooves marked on the upper surface of the cover 20 are the marks of the feeder and the wheat piece. Reference numeral 12 is a band groove for inserting a rubber band and the depth is the same as the band groove 11 and to have a narrow width.

In addition, according to the present invention, the handle grooves 14 and 24 are formed to be inserted into the operator's hand on the interface where the main body 10 and the cover 20 are in contact with each other. The handle grooves 14 and 24 are formed at points coincident with each other on both sides of the main body 10 and the cover 20. The handle grooves 14 and 24 are sized to accommodate a worker's hand in a matched state. When the handle grooves 14 and 24 are used, it is easy to open the cover 20 in the body 10.

In addition, according to the present invention, the locking jaw 26 is formed to protrude to the outer surface of the upper surface of the cover 20 to be engaged with the bottom surface of the main body 10. The box on which the cover 20 is covered by the main body 10 is normally stacked to use the locking jaw 26 so as not to slip on each other for transportation and storage. In the cover 20 having a relatively thin thickness, the locking projection 26 is protruded and concave in the bottom of the main body 10.

Reference numeral 15 denotes a partition wall 15 dividing the space inside the main body 10. The partition wall 15 is used to reinforce a central portion of which the strength is relatively weak in the main body 10 and to classify and accommodate the liquid crystal display device as necessary. The height of the partition wall 15 may be smaller than the corrugated groove 16. In FIG. 3, reference numeral 25 of the cover 20 is formed at a vertically upward position coinciding with the partition wall 15, so that only the width is widened while being the same height as the neighboring tooth groove 27.

In addition, the main body 10 and the cover 20 according to the present invention is applied to a molded article of EPP material mixed with 0.3-2wt% of an antistatic agent such as graphite powder. EPS is slightly inferior to EPP in terms of physical properties, so it is suitable for low and mid-priced products with a clear distribution channel. Unlike synthetic metals, ordinary synthetic resins have the property of being electrically insulating, and thus have the property of accumulating static electricity generated by friction with other materials for a long time. Therefore, various obstacles may be caused to the liquid crystal display accommodated therein due to discharge, suction, and repulsion caused by static electricity charged on the main body 10 and the cover 20.

In order to prevent this, in the process of pelletizing PP resin, an antistatic agent such as carbon (graphite powder) is mixed and foamed. The content of such antistatic agent is about 0.3-2 wt%, more preferably about 0.5-0.8%. As the content of the antistatic agent increases, it is advantageous in terms of antistatic property, but the strength is weakened and it may increase pollutants in recycling.

4 is a configuration diagram showing a state in which the product is accommodated in the box according to the present invention, the operation will be described with reference to FIGS.

First, the liquid crystal display is cut to an appropriate size, and then stored on the corrugated groove 16 and the tooth groove 17 of the main body 10 in order, and after storing, the cover 20 is pressed and sealed, and the band from the outside Wrapped around the band grooves 11 and 21 to complete the packaging. Subsequently, the worker uses the band, the handle groove 24 or the concave groove 13 to load the vehicle or stack it in a warehouse. When stacking boxes containing a liquid crystal display device in a container or a warehouse, a slipping bar is used to prevent sliding accidents. The main body 10 and the cover 20 of the present invention are divided into various colors by adding pigments. Take this easy configuration. Blue, black, red, yellow, green, etc., even if mixed together, the color can be easily distinguished.
