 【detailed description】

The invention will now be described in detail in conjunction with the drawings and embodiments.

2 and FIG. 3, FIG. 2 is a perspective exploded view of the embodiment of the package of the present invention, and FIG. 3 is another perspective exploded view of the embodiment of the package of the present invention, wherein the bottom cover is in an assembled state.

As shown, the package 20 includes a bottom cover 21 and a top cover 22. The bottom cover 21 includes a base 211, a bottom cushioning member 212, and a corner cushioning member 213. A receiving space 23 is disposed on the base 211 to receive the carrier. The base 211 can be designed as a whole hollow cover structure, or can be designed as a base 211 formed by splicing of segmented engineering plastic parts, and the number of engineering plastic parts is at least two. In the embodiment of the present invention, the pedestal 211 has the first cushioning performance, and the pedestal 211 is located at the outermost periphery with respect to the carrier, and is not directly in contact with the carrier. Therefore, the material of the pedestal 211 may be generally buffered. And cheap engineering plastics, such as: ABS (propylene-butadiene-benzenediene copolymer) or foamed PE (polyethylene). In addition, in order to further reduce the material cost and improve the cushioning performance, the material of the susceptor 211 may also be selected as a hollow plate.

The bottom cushioning member 212 is disposed at the bottom of the receiving space 23 of the base 211. The bottom cushion member 212 has a second cushioning property for buffering a portion of the protective carrier that is not buffer-protected by the corner bumper 212 during transportation. The area of the bottom buffer member 212 can be selected to be consistent with the area of the bottom of the receiving space 23 of the base 211, so that the bottom cushioning member 212 can cover the bottom surface of the receiving space 23 of the base 211. In an embodiment of the present invention, the material of the bottom buffer member 212 may be a PP (Polypropylene) film.

The corner buffering member 213 is disposed at a corner of the receiving space 23 of the base 211, and has a shape matching the corner of the carrier and directly contacts the carrier. The corner cushioning member 213 is generally L-shaped, has an L-shaped bottom plate 2131 and an L-shaped side plate 2132, and the side plate 2132 extends upward from the outer side of the bottom plate 2131. In the embodiment of the present invention, a hook may be formed on a surface of the side plate 2132 of the corner buffer member 213 that is in contact with the base 211, and a side surface of the base 211 is provided with a buckle at a position corresponding to the hook. , the snap fit, the corner buffer 213 is fixed on the base 211. Of course, the manner in which the corner buffer 213 is fixed to the base 211 is not limited to the above-mentioned snap fit. For example, glue fixing or double-sided adhesive can be used. Solid way and so on. The corner bumper 213 has a third cushioning performance. When the package 20 receives the carrier, the carrier is directly carried on the corner buffer 213, and the corner buffer 213 cushions the carrier to prevent damage to the carrier due to the collision of the cushioning base 211 during transportation. In the embodiment of the present invention, the material of the corner buffer 213 may be a material with good buffering performance, for example: EPP (Expanded) Polypropylene, polypropylene plastic foam material). The number of the corner buffering members 213 is preferably four, which are respectively located at four corners of the receiving space 23 of the base 211. When the packaging box 20 receives the carrier, the four corner buffering members 213 directly support the four of the carrying materials. The corners can effectively support the carrier and effectively cushion the protection carrier.

Among them, it should be specially stated that the third buffering performance and the second buffering performance are superior to the first buffering performance, and the price of the material with good cushioning performance is generally more expensive than the material with general buffering performance. In the embodiment of the present invention, the base 211 that does not directly serve as the buffer protection carrier is made of a material with general buffering performance, and only the corner buffering member 213 and the bottom buffering member 212 are made of a material with better cushioning performance, and the corner buffering member 213 and the bottom surface buffering layer are used. The material of the piece 212 is used in a small amount, and therefore, the material cost of the package can be effectively reduced.

Referring again to FIGS. 2 and 3, the top cover 22 is covered by the bottom cover 21 such that the package 20 forms a closed receiving space 23. In the embodiment of the present invention, the package 20 is preferably used to house a liquid crystal display panel, and of course, is not limited to housing a liquid crystal display panel.

In an embodiment of the invention, the bottom cover of the unitary package is split into a base, a bottom cushion, and a corner cushion. The bottom cushioning member with the cushioning performance in direct contact with the carrier is disposed at the bottom of the receiving space of the base, and the corner buffering member with better buffering property and direct contact with the carrier is disposed at the corner of the receiving space of the base, instead of The susceptor in direct contact with the carrier is located at the periphery of the bottom cushion member and the corner cushion member, and the cushioning performance is inferior to the bottom cushion member and the corner cushion member. In the above manner, when the package box accommodates the carrier, the corner buffer member directly supports the carrier, and the base supports the carrier indirectly. Therefore, the material of the base can be selected from a relatively cheap material, thereby reducing the cost of the package and thereby reducing the cost. Product Cost.

The above is only the embodiment of the present invention, and is not intended to limit the scope of the invention, and the equivalent structure or equivalent process transformations made by the description of the invention and the drawings are directly or indirectly applied to other related technologies. The fields are all included in the scope of patent protection of the present invention.
