[0016] The embodiments of the present utility model will be described in detail below. The illustrated embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
[0017] In the present utility model, unless otherwise clearly specified and defined, terms such as "assembled", "connected", and "joined" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or connected through an intermediate medium, and can be connected internally between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0018] The technical solutions and their beneficial effects of the present utility model will be made clearer and more definite by further describing the specific embodiments of the present utility model in conjunction with the accompanying drawings of the specification. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.
[0019] The preferred embodiment provided by the present utility model: As Figures 1 to 3 shown, a packaging box includes a box body cardboard 1 and a folding cardboard 2. The box body cardboard 1 is of an integral structure, and the folding cardboard 2 is fixedly connected to the box body cardboard 1 so that the box body cardboard 1 and the folding cardboard 2 form a whole; the connection method between the folding cardboard 2 and the box body cardboard 1 is glue connection.
[0020] The box body cardboard 1 includes a bottom plate 11, a cover plate 12, side plates 13 and a cover tongue 14. The side plates 13 are provided on both sides of the bottom plate 11. The cover plate 12 is connected to one of the side plates 13, and the cover tongue 14 is connected to the cover plate 12. Flanging is provided at the joints of the bottom plate 11, the cover plate 12, the side plates 13 and the cover tongue 14 for folding.
[0021] The folding cardboard 2 is of an integral structure. The folding cardboard 2 includes a fixing plate 21 and a number of waist plates 22. The waist plates 22 are connected to each other. The intersection edges between the waist plates 22 are the fixed crease lines 23 of the folding cardboard 2. The waist plates 22 are folded with the fixed crease lines 23 as the axes. Each waist plate 22 is folded to increase the thickness of the folding cardboard 2. The waist plates 22 are coated with adhesive to strengthen the connection firmness between the waist plates 22. The folding cardboard 2 is fixed to the box body cardboard 1 through the fixing plate 21. A first fold is provided at the intersection of the waist plate 22 and the fixing plate 21. The waist plate 22 is folded with the first fold as the axis to adjust the angle formed by the box body cardboard 1 and the folding cardboard 2.
[0022] The shape of the waist plate 22 is an isosceles trapezoid. The waist plate 22 includes a waist part 26 and a support part 27. A second fold is provided between the waist part 26 and the support part 27. The support part 27 can be folded towards the waist part 26 with the second fold as the axis. The overall shapes of both the waist part 26 and the fixing plate 21 are triangular to cooperate with the folding of the box body shape.
[0023] The support part 27 extends out a bottom plate connection part 29. A reverse fold is provided between the bottom plate connection part 29 and the support part 27. The bottom plate connection part 29 is folded with the reverse fold as the axis. The bottom plate connection part 29 is connected to the bottom plate 11 to strengthen the connection firmness between the folding cardboard 2 and the box body cardboard 1.
[0024] The support part 27 extends out a thickening part 31. The thickening part 31 is coated with glue to be fixed to the waist plate 22. The thickness of the folding cardboard 2 can be increased through the thickening part 31.
[0025] This packaging box provides a new type of folding packaging, which includes a box body cardboard 1 and a folding cardboard 2. The folding cardboard 2 is in the shape of an isosceles trapezoid, and the folding cardboard 2 is provided with a fixed pressing bone line 23, a first folding edge 25, a second folding edge 28, and a reverse folding edge 30. After the waist plates 22 are folded with each other, they form a shape with thin sides and thick middle. When assembling into a box, the folding cardboard 2 is adhered to both sides of the bottom plate 11. The folding cardboard 2 serves as a skeleton to support the whole box body to avoid deformation. The adhered waist plates 22 improve the anti-extrusion force and make the packaging more complete. The fixing plates 21 at both ends of the folding cardboard 2 are respectively connected to the side plates 13 on both sides of the bottom plate 11. The folding between the waist part 26, the fixing plate 21 and the supporting part 27 is realized through the first folding edge 25 and the second folding edge 28. By using the folding and stretching characteristics of the paper to drive the folding, the packaging can be easily flattened and folded into shape, which is convenient for packaging and saves transportation space, and also greatly reduces the cost during production. The advantage of this new type of packaging is that the designer uses the way of folding hard cardboard, and uses the thickness after folding to replace the thin paper mounted cardboard of the traditional old model, which greatly reduces the production cost and production speed, and can also reduce the overall weight of the packaging. The folding cardboard 2 is subjected to edge cutting treatment, so that the total thickness after folding the two sides is thinner than that in the middle, and the extrusion on both sides is reduced when folding the box into shape, so as to achieve a better fit at the connection between the folding card and the bottom plate 11. The folding cardboard 2 and the bottom plate 11 are connected by a tooth knife at the joint, which reduces the paper tension and is not easy to bounce up, and reduces the extrusion at the folding position. At both ends of the folding cardboard 2, a certain interval is left at the crease, so that when the packaging is flattened, there is an appropriate stretching space, and the interval position is adjusted according to the width of the slot on the bottom plate 11. The innermost folding surface of the folding cardboard 2 is reduced inward to prevent the inner folding surface from being larger than the outer one when folding the folding card into shape. The second folding edge 28 adopts a reverse folding bone, which serves as a function of stretching and flattening the folding card when the folding cardboard 2 and the two ends of the bottom plate 11 are adhered.
