[0051] With reference to Figures 1-3 As shown, according to an embodiment of the present application, a packaging structure includes: a box body 2, a buffer part 1 and a sealing structure. The buffer part 1 is arranged inside the box body 2; the sealing structure is arranged between the buffer part 1 and the box body 2. A sealing structure is arranged between the buffer part 1 and the box body 2 to prevent dust from entering the gap between the packaging box and the buffer part 1, and to prevent dust from entering during product transportation and contaminating the internal product.

[0052] Further, the box body 2 is of a one-piece structure; the one-piece structure includes a first top plate 24, a first side plate 22, a bottom plate 21, a second side plate 23 and a second top plate 25 which are sequentially connected by folding lines.

[0053] Further, an installation part is arranged on the buffer part 1, and the installation part is used for installing the item to be packaged 6.

[0054] Further, the first side plate 22 and the second side plate 23 are folded upward along the folding line to form the side wall of the box body 2; the first top plate 24 and the second top plate 25 are folded along the folding line to form the top flap of the box body 2, and the second top plate 25 overlaps above the first top plate 24;

[0055] And / or, the box body 2 is a hollow structure with openings at both ends, so that the box body 2 completely wraps the internal item to be packaged 6.

[0056] With reference to Figures 3-6 As shown, the present application also discloses some embodiments. When the box body 2 is a hollow structure with openings at both ends, the position of the sealing structure corresponds to the position of the openings;

[0057] And / or, when the box body 2 is a hollow structure with openings at both ends, the end of the buffer part 1 corresponds to the position of the openings;

[0058] And / or, the sealing structure is a concave-convex mating structure, and the position of the sealing structure corresponds to the position of the opening, which can effectively prevent dust from entering the interior of the box body 2 through the opening, thereby contaminating the workpiece 6 to be packaged.

[0059] Furthermore, when the sealing structure is a concave-convex mating structure, the concave-convex mating structure includes a first concave-convex structure and a second concave-convex structure that cooperate with each other; the first concave-convex structure is provided on the box body 2; and / or, the second concave-convex structure is provided on the buffer part 1.

[0060] With reference to Figures 7-9 As shown, the present application also discloses some embodiments. The second concave-convex structure includes a flange, and the flange is provided at the end of the buffer part 1; the flange extends outside the box body 2.

[0061] Furthermore, the first concave-convex structure includes a relief groove; the relief groove corresponds to the position of the flange.

[0062] Furthermore, the end face of the buffer part 1 includes a bottom edge, a side edge, and a top edge; the flange includes a first flange 34; and the first flange 34 is provided at the side edge of the buffer part 1;

[0063] And / or, the flange includes a second flange 35, and the second flange 35 is provided at the top edge of the buffer part 1.

[0064] Furthermore, when the flange includes a first flange 34, the side edge includes a first side edge; the first flange 34 includes a first side flange; the first side flange is provided at the first side edge;

[0065] And / or, the side edge includes a second side edge; the first flange 34 includes a second side flange; the second side flange is provided at the second side edge.

[0066] Furthermore, when the flange includes a first flange 34 and the first flange 34 includes a first side flange, the relief groove includes a first relief groove 31, and the first relief groove 31 is formed on the second side plate 23; the first relief groove 31 corresponds to the first side flange;

[0067] And / or, when the flange includes a first flange 34 and the first flange 34 includes a first side flange, the relief groove includes a second relief groove 32; the second relief groove 32 is provided on the first side plate 22, and the second relief groove 32 corresponds to the second side flange;

[0068] And / or, when the flange includes a second flange 35, the relief groove includes a third relief groove 33; the third relief groove 33 is provided on the first top plate 24, and the third relief groove 33 corresponds to the second flange 35.

[0069] Further, when the flange includes the first flange 34, the first flange 34 extends from the bottom end to the top end of the side edge, preventing dust from entering the interior of the package from the side and the overlapping part of the upper lid, and contaminating the product;

[0070] And / or, when the flange includes the first flange 34 and the second flange 35, the second flange 35 is connected to the first flange 34. Further, the second flange is connected to the first side flange. The box body 2 is formed by folding a one-piece corrugated cardboard. Before the goods arrive, the first relief groove 31, the second relief groove 32, and the third relief groove 33 are cut out, and Figure 1 pre-pressing is performed on the shaded part in []. The thickness after pre-pressing is less than 5 mm. The pre-pressing width is the same as or slightly wider than the width of the protective parts such as the buffer part 1, and is matched with the position of the protective parts such as the buffer part 1 to facilitate folding and sealing with sealing tape; the first side flange extends outward through the first relief groove 31; the second side flange extends outward through the second relief groove 32, and the second flange 35 extends outward through the third relief groove 33; and the second flange 35 is connected to the first flange 34. Through the cooperation of the flange and the relief groove, the gap between the box body 2 and the buffer part 1 is filled, that is, the corners after the packaging box is folded and formed and the gaps between the two side cardboard and the protective parts are filled, thereby preventing dust from entering.

[0071] Further, the box body 2 is elongated; the extending direction of the folding line is the length direction of the box body 2; the width of the first top plate 24 is d1; the width of the second top plate 25 is d2; the width of the bottom plate 21 is d3; where d1 < d3; and / or, d2 = d3.

[0072] Further, 10 mm ≤ d3 - d1 ≤ 15 mm, which increases the overlapping area of the two lids, effectively improves the anti-step-on strength of the overall package. The lengthening of the upper lid part can increase the stress area. In the case of canceling the support plate or the anti-step-on plate, it can play a role in resisting trampling; the width of the upper lid, that is, the first top plate 24, is 10 - 15 mm less than that of the bottom plate 21. If it is too short, after the second top plate 25 and the first top plate 24 are folded and formed, it is easy to collapse in the middle when stepped on. If it is too long, it will hit the side plate during folding, and will cause too large a resilience force when the second top plate 25 is folded. And it effectively prevents dust from entering the interior of the package from above.

[0073] Referring to Figures 10-12 As shown, the present application also discloses some embodiments. The sealing structure includes a sealing member, and the sealing member is disposed on the inner surface of the box body 2 or the outer surface of the buffer part 1. When the sealing member is disposed on the outer surface of the buffer part 1, after folding, the internal width dimension of the packaging box is slightly smaller than the width of the protective parts such as packaging foam, so that the protective parts slightly squeeze the sponge, thereby blocking dust.

[0074] Further, the material of the sealing member is an elastic material;

[0075] And / or, when the seal is disposed on the inner surface of the box body 2, a first groove 37 is provided on the buffer portion 1, and the first groove 37 is adapted to the seal, so that after the packaging box is folded and formed, it cooperates with the groove on the foam to prevent dust from entering;

[0076] And / or, the seal is a sealing strip, and the sealing strip extends circumferentially around the central axis of the opening.

[0077] Refer to Figure 13 As shown, the present application also discloses some embodiments, and a sealing tape 4 is pasted at the connection position of the first top plate 24 and the second top plate 25 to fully fix and prevent bursting.

[0078] Further, the sealing tape 4 extends along the length direction of the box body 2.

[0079] Further, the sealing tape 4 extends to the buffer portion 1; the length of the sealing tape 4 on the buffer portion 1 is 100-120 mm.

[0080] Further, the packaging structure further includes a packing belt 5, and the packing belt 5 is disposed outside the box body 2 and is used for fastening the box body 2, the item to be packaged 6 and the buffer portion 1.

[0081] Further, the extending direction of the packing belt 5 is the same as the length direction of the box body 2, and two packing belts 5 are provided. The two packing belts 5 are respectively located on both sides of the sealing tape 4 and are used for fixing the internal product and the packaging.

[0082] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above advantageous ways can be freely combined and superimposed.

[0083] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above is only the preferred implementation manner of the present application.
