DETAILED DESCRIPTION

(6) The technical solutions of the present application will be described in detail with reference to the drawings, so as to enable the person skilled in the art to better understand the solution of the present application but not to limit the scope of the present application accordingly.

(7) As shown in FIG. 1, an anti-theft packaging case having double bottoms and double covers includes a top cover portion, side plates 10, and a bottom plate portion. The top cover portion includes an upper cover 11, a lower cover 12, a left cover 13, and a right cover 14. The bottom plate portion includes a left bottom plate 23, a right bottom plate 24, an inner bottom plate 21, and an outer bottom plate 22. The upper cover 11 is provided with a tear strip 111 and an antitheft line 113. The tear strip 111 is provided with a strengthening rib 112. The tear strip 111 is formed by providing several stub cut holes, curved holes or circular holes extending through the upper cover and apart from each other along two parallel lines at a middle portion of the upper cover 11. The strengthening rib 112 is one or more strands or plastic strips arranged in the vicinity of the center of an inner side of the tear strip 111 in an extending direction of the tear strip 111. The anti-theft line 113 is formed by two groups of symmetrically arranged cutter lines, thus achieving the anti-theft and anti-loss, and reminding customers to identify whether the packaging was opened before, saving a lot of tape, and improving the efficiency in opening the packaging case and saving time.

(8) Furthermore, the packaging case is a closed case with double covers. The left cover 13 and the right cover 14 are configured to close the packaging case, and in the packaging, the lower cover 12 is folded over the left cover 13 and the right cover 14, and then the upper cover 11 is folded over the lower cover 12. An outer surface of the bottom of the lower cover 12 is provided with an adhesive bonding area 122, and in the packaging, an inner surface of the upper cover 11 is adhered to the adhesive bonding area 122. Front ends of the left cover 13, the right cover 14 and the lower cover 12 are provided with notches 131, 141 and 121 respectively, and each of the notches 131, 141 and 121 may have a semicircular shape, a square shape or a trapezoidal shape. The packaging case is a closed case with double bottoms, the left bottom plate 23 and the right bottom plate 24 are configured to close the packaging case, and in the packaging, the inner bottom plate 21 is folded over the left bottom plate 23 and the right bottom plate 24, and then the outer bottom plate 22 is folded over the inner bottom plate 21. An outer surface of the inner bottom plate 21 is provided with an adhesive bonding area 211, and in the packaging, an inner surface of the outer bottom plate 22 is adhered to the adhesive bonding area 211. Each of the corners has a rounded structure, in this way, the structure with double bottoms and double covers greatly reduces risks that the packaging case is unsealed, is cracked or stolen, and has superior anti-theft performance, and the use of a double-sided adhesive tape or hot-melt adhesives with a high original adhesion, a strong static shear adhesion and a high peel strength to seal the package makes it hardly to remove the double-sided adhesive tape or hot-melt adhesives from the place where the case is sealed.

(9) FIG. 2 shows a solution suitable for a packaging case that is relatively narrow, for example, in the case that the packaging case has a width less than or equal to 5 cm, it is recommended to use the solution shown in FIG. 2. The structure of FIG. 2 is also applicable to a big packaging case. Compared with the solution in FIG. 1, the bottom plate and the side plates in the solution in FIG. 2 are unchanged, and the adhesive bonding area of the lower cover 12 of the top plate is moved downwards, and the upper cover 11 is lengthened, and a line 114 is a creasing line. When the side plates 10 are connected to form a case shape, the upper cover 11 is bent inwards by the creasing line 114, such that the inner surface of the upper cover 11 is adhered to the adhesive bonding area 122, thus finishing the sealing of the top cover.

(10) Only preferred embodiments of the present application are described hereinbefore, and the technical solutions of the present application are not limited thereto. Any known modifications made by the person skilled in the art on the basis of the main technical concept of the present application are within the technical areas claimed by the present application, the specific scope of the present application is indicated by the disclosure of the claims.
