As shown in fig. 1 to 6, an embodiment of the present invention provides a packaging box 100, where the packaging box 100 includes a top panel 10 and a surrounding panel assembly, the top panel 10 and the surrounding panel assembly are formed by folding a piece of paperboard, where the surrounding panel assembly surrounds an upper opening and a lower opening, the top panel 10 is connected to the surrounding panel assembly and closes the upper opening, the surrounding panel assembly includes four side panels 20 connected in sequence, and the side panels 20 are arranged in a double-layer overlapping structure.

The packing box 100 provided by the embodiment of the invention is formed by folding a piece of paperboard, the paperboard forms a top plate 10 and a surrounding plate assembly of the packing box 100 through folding, and an accommodating cavity is defined between the top plate 10 and the surrounding plate assembly and used for accommodating packaged articles; wherein, four curb plates 20 that the bounding wall subassembly included all set up to double-deck superimposed structure, that is to say that every curb plate 20 includes two-layer board, have increased the intensity of packing box 100 from this, have improved the protective capacities to the inside packaged goods of packing box 100.

It should be noted that, the packaging box 100 provided in this embodiment is mainly used for packaging household appliances such as a refrigerator and an ice chest, except for the surrounding plate assembly and the top plate 10, the packaging box 100 further includes a foam bottom pad, the top plate 10 includes two rocking covers 11, when the refrigerator is packaged, the surrounding plate assembly is firstly seated on the foam bottom pad, the two rocking covers 11 of the top plate 10 are opened, the refrigerator is placed into the containing cavity, then the rocking covers 11 are closed and sealed, and finally the packaging box 100 is wholly packaged by the packaging belt.

For the convenience of understanding, the following embodiments will specifically describe the above paper boards, and the paper boards may be configured as square paper boards, rectangular paper boards with non-square shapes, or polygonal paper boards, for example, as shown in fig. 1, the paper boards may be configured as polygonal paper boards with approximately rectangular outlines.

In this embodiment, a part of the area of the cardboard can be used as the top panel 10 of the packing box 100, and part of the remaining area of the cardboard can be folded onto another part of the panel, so that the two overlapped panels together can be used as the side panels 20 of the packing box 100, and then the side panels 20 are folded to stand up, i.e. perpendicular to the top panel 10, and the adjacent side panels 20 are connected together to form the surrounding panel assembly, thereby the side walls of the packing box 100 have a double-layer structure.

Specifically, as shown in fig. 1, in some embodiments of the present invention, two transverse creases 30 and two longitudinal creases 30 are disposed on the cardboard, and it should be noted that two creases 30 in this embodiment are parallel and perpendicular to the other two creases 30, and two of the creases 30 that are parallel are transverse creases 30, and the other two are longitudinal creases 30.

It will be appreciated that each fold 30 extends from one edge of the sheet to the opposite edge, so that the four folds 30 divide the sheet into a nine-grid pattern, which in this embodiment includes a cross panel and four corner panels 50 in the middle for ease of understanding, and the sub-division is described in this embodiment. The central block 41 of the cross-shaped plate is used for forming the top plate 10 of the packing box 100, and it should be noted that the central block 41 in this embodiment refers to an area enclosed by two transverse creases 30 and two longitudinal creases 30.

The four corner plate blocks 50 are respectively positioned at four included angles of the cross-shaped plate block, and the four corner plate blocks 50 and the extending blocks 42 of the cross-shaped plate block are used for forming a coaming assembly of the packing box 100; it should be noted that the extended blocks 42 in this embodiment refer to the remaining four areas of the cross-shaped plate except the central block 41. It will be appreciated that the four corner tiles 50 are integral with the extended blocks 42, the central block 41 of the cross-shaped tile.

Further, in order to make the heights of the four side panels 20 of the packing case 100 equal, the adjacent sides of the four protruding blocks 42 have the same length, and thus the corner panel 50 located between the two protruding blocks 42 is shaped as a square, and thus, in some embodiments of the present invention, the four corner panels 50 are shaped as squares having the same area.

Specifically, in the process of forming the side panel 20 of the packing box 100, the corner panel 50 may be folded onto one of the extension blocks 42 adjacent thereto, that is, four corner panels 50 are respectively folded onto four of the extension blocks 42, and each corner panel 50 is overlapped with one of the extension blocks 42 to form one side panel 20 of the packing box 100. In addition, after the corner panel 50 and the extended block 42 are overlapped, the corner panel 50 and the extended block 42 may be connected by gluing or binding, thereby improving the structural stability of the side panel 20.

In some embodiments of the present invention, the corner plate 50 may be integrally folded and attached to the extension block 42, or a partial region of the corner plate 50 may be folded and attached to the extension block 42. On this basis, the area of the corner panel 50 may be equal to or less than the area of the extended block 42 to ensure that the area of the inner structure of the side panel 20 is equal to or less than the area of the outer structure.

It will be appreciated that some areas of the sheet may be folded by providing a cut in the sheet, for example, as shown in figure 1, in some embodiments of the invention, a cut 60 is cut in each corner panel 50, the cut 60 being coincident with the edge of the cross-shaped panel, i.e. with the fold 30; or may be located close to the edge of the cross-shaped panel, i.e. at a distance from the fold 30.

It should be noted that, in the present embodiment, the notch 60 may be a slit formed by cutting, or may be a notch with a certain width; that is, the panels on both sides of the slit 60 in this embodiment may have a certain distance therebetween, or may be closely attached without a distance therebetween, but may be offset from each other in a direction perpendicular to the paper board.

In the embodiment shown in fig. 1, the cuts 60 are disposed near the edges of the cross-shaped plate, the cuts 60 are spaced from the edges of the cross-shaped plate, the four cuts 60 are cut perpendicularly inward from the four edges, and extend to the nearest fold 30, that is, the cuts 60 do not exceed the fold 30, as shown in fig. 1, every two adjacent cuts 60 are perpendicular, and the four cuts 60 are arranged in a cyclone shape on the cardboard.

On this basis, in each corner plate block 50, the area between the cut 60 and the crease 30 perpendicular to the cut 60 is a folding plate 51, that is, the cut 60, the crease 30 perpendicular to the cut 60 and two edges of the corner plate block 50 together form a folding plate 51, and the folding plate 51 is used for being folded and attached on the extended block 42 along the crease 30, that is, the cut 60 is arranged so that the area on the corner plate block 50 outside the cut 60 forms the folding plate 51, as shown in fig. 2, the folding plate 51 can be folded onto the adjacent extended block 42 for forming the side plate 20 of the packing box 100.

Taking the cardboard shown in fig. 1 as an example, the central block 41 of the cross-shaped board is a rectangle with unequal length and width, and it can be understood that the width of the two extending blocks 42 in the left-right direction of the cross-shaped board is unequal to the width of the two extending blocks 42 in the up-down direction. On this basis, in some embodiments of the present invention, the width of the folding plate 51 in the folding direction is equal to the width of the protruding block 42 to which it is to be attached in the folding direction.

It can be understood that, when the folding plate 51 is folded, the width along the folding direction is equal to the width along the folding direction of the protruding block 42, which not only ensures the area range of the double-layer structure of the side plates 20, but also ensures that the folding plate 51 does not exceed the boundary of the protruding block 42 after being overlapped on the protruding block 42, and avoids affecting the connection between the subsequent adjacent side plates 20.

For easy understanding, the above embodiment is described below by using a specific example, as shown in fig. 1 and fig. 2, the transverse folds 30 of the four folds 30 are respectively the first transverse fold and the second transverse fold from top to bottom, and the longitudinal folds 30 are respectively the first longitudinal fold and the second longitudinal fold from left to right; the four corner plates 50 are respectively a first plate, a second plate, a third plate and a fourth plate along the clockwise direction, wherein the first plate is positioned at the upper left corner of the cross-shaped plate, the second plate is positioned at the upper right corner of the cross-shaped plate, the third plate is positioned at the lower right corner of the cross-shaped plate, and the fourth plate is positioned at the lower left corner of the cross-shaped plate.

Specifically, a first cut is cut in the first plate block along the longitudinal direction at a position close to the first longitudinal crease, the first cut extends from the edge of the paperboard to the first transverse crease, and a first folding plate is enclosed between the first cut and the first transverse crease; a second cut is longitudinally cut at a position, close to the first transverse crease, in the second plate block, the second cut extends from the edge of the paperboard to the second longitudinal crease, and a second folding plate is enclosed between the second cut and the second longitudinal crease; a third cut is cut in the third plate body at a position close to the second longitudinal crease along the longitudinal direction, the third cut extends from the edge of the paperboard to the second transverse crease, and a third folding plate is enclosed between the third cut and the second transverse crease; and a fourth cut is longitudinally cut at a position close to the second transverse crease in the fourth plate block, the fourth cut extends to the first longitudinal crease from the edge of the paperboard, and a fourth folding plate is enclosed between the fourth cut and the first longitudinal crease.

According to the arrow direction shown in fig. 2, the first folding plate can be folded along the first transverse fold line onto the extended plate 42 at the left half of the cross-shaped plate, the second folding plate can be folded along the second longitudinal fold line onto the extended plate 42 at the upper half of the cross-shaped plate, the third folding plate can be folded along the second transverse fold line onto the extended plate 42 at the right half of the cross-shaped plate, and the fourth folding plate can be folded along the first longitudinal fold line onto the extended plate 42 at the lower half of the cross-shaped plate, so as to finally form the paperboard structure shown in fig. 3.

The side panels 20 in figure 3 are folded inwardly in the direction of the arrows and are erected, i.e. perpendicular to the central region 41 of the cross-shaped panel, and the side panels 20 are connected to form a closure assembly for the container 100.

In some embodiments of the present invention, the distance between each cut 60 and the edge of the adjacent cross-shaped board is equal, on the basis of the above embodiments, the edge of the cross-shaped board is the fold 30, and the distance between the cut 60 and the edge of the cross-shaped board is the distance between the cut 60 and the fold 30, as shown in fig. 3, the block between the cut 60 and the edge of the cross-shaped board can be folded along the fold 30, and after folding, the connecting tongue 70 for connecting the adjacent side panels 20 can be formed, in this embodiment, the arrangement with equal distances makes the widths of the formed connecting tongues 70 equal, thereby ensuring the stability of the internal structure of the packaging box 100.

Further, as shown in fig. 3, the connecting tongue 70 is formed by folding the area between the cut 60 and the fold 30, and then the side panels 20 connected with the connecting tongue 70 are erected, so that the connecting tongue 70 is respectively attached to the inner walls of the adjacent side panels 20, and on this basis, the connecting tongue 70 is connected with the side panels 20, and in some embodiments of the present invention, the connecting tongue 70 is connected with the adjacent side panels 20 by box pins, thereby ensuring the reliability of the packing box 100.

The enclosing plate assembly is enclosed to form an upper opening and a lower opening, wherein the upper opening is sealed by a central block 41 of the cross-shaped plate, the central block 41 is used as a top plate 10 of the packing box 100 and is enclosed with the enclosing plate assembly to form an accommodating cavity; the lower opening is used for being sleeved and matched with the foam bottom cushion in the packaging process.

It will be appreciated that, as shown in fig. 4, after the side panels 20 are connected, the package 100 is entirely inverted to the orientation shown in fig. 5, with the top panel 10 facing upward and the top panel 10 of the package 100 including two flaps 11, and in this embodiment, the two flaps 11 may be formed by cutting the central block 41.

In particular, in some embodiments of the invention, as shown in fig. 5, the central block 41 is cut with a first cut 81, a second cut 82 and a third cut 83, wherein the first cut 81 and the second cut 82 coincide with two parallel creases 30, respectively, i.e. with two edges of the central block 41. When the central block 41 is a non-square rectangle, the first slit 81 and the second slit 82 may coincide with two shorter sides, the third slit 83 is vertically disposed between the first slit 81 and the second slit 82, and two ends of the third slit 83 penetrate the first slit 81 and the second slit 82, thereby forming two flaps 11. Preferably, third slits 83 are cut along the axis of symmetry of central block 41, thereby making the areas of the two flaps 11 equal for ease of packaging and sealing.

In summary, the packing box 100 provided in the embodiment of the present invention is formed by folding a piece of paperboard, and the top plate 10 and the surrounding plate assembly of the packing box 100 are formed by folding the paperboard, in this embodiment, four side plates 20 having a double-layer structure are formed by using the folded paperboard, and the strength of the side plates 20 having the double-layer structure is high, so that the possibility of damage to the packing box 100 is reduced, and further, it is ensured that the packed articles inside the packing box 100 are not worn; the packing box 100 provided by the embodiment of the invention is not only convenient to assemble, but also greatly saves materials and solves the problem that two layers of packing boxes waste materials in the prior art compared with the mode that two packing boxes are sleeved together in the prior art.
