SPECIFIC MODES OF IMPLEMENTATION

(14) The following implements a detailed description of this utility model in combination with the figures and the specific implementations.

Embodiment 1

(15) As shown in FIG. 1 and FIG. 5, the packing box of this embodiment is narrow at the bottom and wide at the top, and includes a protective box body 1 composed of a bottom surface and four multiple sidewalls as well as an elastic air-filled layer 3 laminated on the inside of the protective box body 1, said elastic air-filled layer 3 being set with an air hole 4, and said air hole 4 being inlaid on said protective box body 1.

(16) As shown in FIG. 3, FIG. 4, and FIG. 6, the top opening of said protective box body 1 is arranged with a separable box cover 2, and protective box bodies 1 of the same external dimensions can be stacked together when not loaded with products, thereby raising the space utilization rate. The side walls of said protective box body 1 are extended to the outside at the top opening and form a convex ridge 5; said separable box cover 2 is set on the outside with a fastening belt fixing seat 6, said fastening belt fixing seat 6 has retractable fastening belts 7 set at the various corners of the opening of the protective box body 1, the ends of said retractable fastening belts are fixed to corner elements 8 at the box corners, and said corner elements 8 at the box corners fit into the corners and convex ridges 5 of the protective box body opening, thereby sealing the packing box.

(17) Preferably, said fastening belt fixing seat 6 is connected to the separable box cover 2 using screws, and a rotary handle is set at the top of the fastening belt fixing seat 6, and the screw-in depth is adjusted via the rotary handle, controlling the degree of tension of the retractable fastening belt 7, making the protective box body 1 fix tightly to the separable box body.

(18) As shown in FIG. 2, FIG. 4, and FIG. 6, said side walls are set with a box cover boss 9 at the top of the inside of the protective box body 1 in order to place the separable box cover 2, and preferably, when said corner elements 8 at the box corners are fitted onto the convex ridge 5, the horizontal planes of both the corner elements 8 at the box corners and the separable cover 1 become parallel.

(19) Even more preferably, an elastic protective body is adhered to the inside of said separable box cover.

(20) Said elastic protective body is able to adopt a shock-absorbing air column bag and is able to adopt an elastic air-filled layer 3 similar to the type on the inside of the protective box body 1.

(21) This embodiment has corresponding modes of operation depending on changes in the specific structure:

(22) 1) The separable box cover 2 adopts a shock-absorbing air column bag, and so the goods loaded must be placed within the protective box body 1, covered with the separable box cover 2, and the corner elements 8 at the box corners fitted onto the convex ridge 5, and filled with a suitable volume of air until the elastic air-filled layer 3 firmly holds the goods to the shock-absorbing air column bag, and the operation is reversed to remove the goods;

(23) 2) The separable box cover uses an elastic air-filled layer 3, therefore a small volume of air is filled onto the elastic air-filled layer 3 of the separable box cover 2, covering the separable box cover 2, and fitting the corner elements 8 at the box corners to the convex ridge 5, then a suitable volume of air is filled into the elastic air-filled layers 3 of the protective box body and the separable box cover, for ease of fixing the goods to the elastic air-filled layer 3; the operation is reversed to remove the goods.

Embodiment 2

(24) As shown in FIG. 7, FIG. 8, FIG. 9, FIG. 10, and FIG. 12, the packing box in this embodiment includes a rotary connection on one side, and the upper box body 10 and lower box body 11 latched on the remaining side, and the upper box body 10 and lower box body 11, and the upper box body 10 and lower box body 11 are closed and sealed by a zipper 12, and protective box bodies 1 of the same dimensions can have the upper box bodies 10 and lower box bodies 11 respectively stacked together when not loaded with goods so as to increase the spatial utilization rate.

(25) As shown in FIG. 8, the top of the upper box body 10 and lower box body 11 of the mating sides are set with a latch assembly; and more preferably, said latch assembly is a pin and sealing strip.

(26) As shown in FIG. 10, the upper box body 10 and lower box body 11 are connected via a leaflet element 15 on the rotary side; and more preferably, the air hole 4 of said elastic air-filled layer 3 is set between two leaflet elements 15 on the rotary side.

(27) As shown in FIG. 11, the packing box of this utility model exhibits a hamburger box shape, and after the upper box body 10 and lower box body 11 are closed, the zipper 12 is pulled up, locking the latch 13 and the seal strip 14, and a suitable amount of air filled via the air hole 4 making the elastic air-filled layer 3 expand and firmly hold the goods, and the operation is reversed to remove the goods.

(28) It must be emphasized that the above is merely a more-preferred embodiment, the shape, etc., of the protective box body 1 is not particularly limited with relation to any of the shapes of this utility model, and all simple modifications, equivalent changes, and decorations performed on the above embodiments according to the technical substance of this utility model shall still be within the scope of the technical scheme of this utility model.
