It should be understood that the embodiments described herein are only for the purpose of illustrating and explaining the present utility model and are not intended to limit the present utility model.

[0038] Figure 1 shows the structure of the packaging structure 1 in some embodiments according to the present utility model, Figure 2A and Figure 2B shows the process of opening the packaging structure 1 in some embodiments according to the present utility model, Figure 3 shows the developed view of the first blank in some embodiments according to the present utility model, Figure 4 shows the developed view of the second blank in some embodiments according to the present utility model. The following will describe the packaging structure 1 in conjunction with Figures 1-4 the above.

[0039] As Figure 2A and Figure 2B described, the packaging structure 1 includes an inner box 11 and an outer box 12. The inner box 11 is set in a preset three-dimensional shape, Figure 2A and Figure 2B The hatched part in shows the inner box 11. The preset three-dimensional shape is, for example, Figures 1-2B the shape similar to an apple shown in. In other embodiments, the inner box 11 can also be set in a pyramid, prism, frustum of a pyramid, cuboid, 32-sided polyhedron similar to a football, or other three-dimensional shapes. The shape of the inner box 11 can be designed according to actual needs. A cavity can be provided inside the inner box 11 to accommodate the commodity to be packaged. For example, the shape of the inner box 11 is set to be similar to an apple shape, and the commodity to be packaged can be an apple or a finished product of an apple.

[0040] In some embodiments, the inner box 11 is made of paper material by folding. The shape of the inner box 11 is preferably set such that all surfaces are flat, which is beneficial to simplifying the processing process and can improve the structural stability. For example, Figure 1 the inner box 11 shown in is similar to an apple shape, but all of its surfaces are flat.

[0041] As Figure 1 shown in Figure 1 , the outer box 12 is disposed circumferentially on the outer side of the inner box 11. For example, the outer box 12 can be configured to completely cover the inner box 11, or cover a part of the structure of the inner box 11.

[0042] The outer box 12 includes a first structural layer 121 and a second structural layer 122. The first structural layer 121 is formed by surrounding the outer circumference of the inner box 11 with a first blank 21 (as Figure 3 shown). For example, the two ends of the first blank 21 in the horizontal direction (the direction in Figure 3 Figure 3 ) are close to each other head to tail, and surround the outer circumference of the inner box 11 to form the first structural layer 121. Figure 3 In a preferred embodiment of the present invention, the first structural layer 121 and the surface of the inner box 11 can be mutually adhered. For example, the inner surface of the first blank 21 is adjacent to the outer surface of the inner box 11, reducing the shaking amplitude of the inner box 11 in the outer box 12, which is beneficial to protecting the inner box 11 and the goods packaged therein. In some other embodiments, a certain gap can also be provided between the first structural layer 121 and the surface of the inner box 11, which can provide a certain processing tolerance and reduce the processing accuracy requirements.

[0043] There is no full - scale fixed connection between the first structural layer 121 and the inner box 11. Point connections can be formed at some positions between the first structural layer 121 and the inner box 11, or it can be configured that there is no connection between the first structural layer 121 and the inner box 11.

[0044]

[0045] The second structural layer 122 is formed by surrounding the outer circumference of the first structural layer 121 with a second blank 22 (as Figure 4 shown), and the second blank 22 and the first blank 21 are adhered and fixed.

[0046]

[0047]

[0047] In some embodiments, for example, the first blank 21 surrounds the outer circumference of the inner box 11, the outer surface of the first blank 21 has an adhesive, and the second blank 22 can be disposed around the outside of the first structural layer 121 and adhered and fixed to the first blank 21. In some other embodiments, an adhesive can be provided on the side of the second blank 22 facing the first structural layer 122, or adhesives can be provided on the surfaces of both the first blank 21 and the second blank 22 to glue and fix the first blank 21 and the second blank 22.

[0048] At least a part of the second blank 22 is not parallel to the surrounding direction of the first structural layer 121 relative to the surrounding direction of the first blank 21 relative to the inner box 11. For example Figure 3 As shown in, the first blank 21 is wound around the outer circumference of the inner box 11 in the horizontal direction, and the second blank 22 can be arranged to be wound around the circumference of the first structural layer 121 at least partially in a non-horizontal direction. For example, the second blank 22 is inclined at a certain angle relative to the horizontal direction at least at some positions.

[0049] Such as Figure 3 As shown, in this embodiment, the first blank 21 is processed with a fragile part 211, and the position of the fragile part 211 corresponds to the surrounding direction of the second blank 22. When the outer box 12 is opened along the surrounding direction of the second blank 22, the first blank 21 is damaged at the position of the fragile part 211. The fragile part 211 can be set as an intermittent break line, with some positions remaining connected and some positions being perforated. When subjected to shear force, the first blank 21 breaks and is damaged at the position of the fragile part 211.

[0050] In this embodiment, the first structural layer 121 formed by the first blank 21 can wrap the inner box 11. When the first blank 21 is folded around the inner box 11, the head and tail may not be fixedly connected. By using the fact that the surrounding directions of the first blank 21 and the second blank 22 are at least partially non-parallel, the outer box 12 is locked in at least two directions. In some embodiments, only the head and tail ends of the second blank 22 need to be fixed, and no additional insertion and fixing structure needs to be provided.

[0051] Furthermore, the inner box 11 can be arranged to have different cross-sectional dimensions in different horizontal planes, forming a shape with a large middle cross-sectional dimension and small cross-sectional dimensions at both ends. By using the structure of the inner box 11 to limit the dispersion of the first blank 21 and the second blank 22, and making the first blank 21 and the second blank 22 fit and fix, a structurally stable outer box 12 can be formed.

[0052] In this embodiment, through the mutual cooperation of the first blank 21 and the second blank 22, the inner box 11 is packaged. And when the outer box 12 is opened, along the surrounding direction of the second blank 22, the first blank 21 can be broken and damaged, which can not only open the outer box 12, but also the second blank 22 can provide a greater degree of design freedom, making the outer box 12 more interesting. For example Figure 2A And Figure 2B As shown, both the inner box 11 and the outer box 12 are arranged in a shape similar to an apple. The surrounding direction of the second blank 22 can be set to be similar to the direction when peeling an apple. When opening the outer box 12, the outer box 12 can be opened by winding along one end of the second blank 22, which improves the user experience. And the shape and opening method of the outer box 12 can also be set to fit the characteristics of the packaged commodity, further improving the user experience.

[0053] According to a preferred embodiment of the present utility model, the first blank 21 is circumferentially disposed around the outer side of the inner box 11 along a first direction, and at least a part of the second blank 22 is circumferentially disposed around the outer side of the first structural layer 121 along a second direction inclined with respect to the first direction.

[0054] As Figure 3 shown in the first blank 21, in a preferred embodiment, it can be formed into a ring with the head and tail approaching each other in the horizontal direction and circumferentially disposed around the inner box 11, where the first direction is the horizontal direction, and the structural sheets on the upper and lower sides of the first blank 21 are bent towards the inner box 11, for example, folded to fit the outer surface of the inner box 11.

[0055] As Figure 4 shown, the second blank 22 is generally a bent strip shape, circumferentially disposed around the surface of the first structural layer 121 for at least one week, and the circumferential angle is not less than 360°. Preferably, the second blank 22 is circumferentially disposed around the surface of the first structural layer 121 for multiple weeks. At least a part of the second blank 22 is circumferentially disposed around the outer side of the first structural layer 121 along the second direction, and the second direction is a non-horizontal direction.

[0056] In the second blank 22, a part of the structure can be circumferentially disposed around the outer side of the first structural layer 121 along the first direction, specifically for example Figure 2A shown in the packaging structure 1, where the first direction is generally the horizontal direction, the direction of the diagonal line 221 is the second direction, the second blank 22 is circumferentially disposed along the second direction (the direction of the diagonal line 221) at the position of the diagonal line 221, and the other parts of the second blank 22 are circumferentially disposed along the first direction. The shape of the second blank 22 after being fully unfolded is generally Figure 4 the bent strip shape shown.

[0057] In some embodiments of the present utility model, the sides of the second blank 22 are adjacent to each other on the surface of the first structural layer 121, for example Figure 2A and Figure 2B shown, where the second blank 22 is circumferentially disposed around the outer side of the first structural layer 121, and the side positions of the second blank 22 are adjacent to each other with the side positions of the second blank 22 after one week of circumferential arrangement, so that the second blank 22 covers a larger range of the first structural layer 121.

[0058] In other embodiments, the sides of the second blank 22 can also be arranged to be spaced apart from each other on the surface of the first structural layer 121, which can achieve different appearance effects, and at the same time, it can also cooperate with the circumferential direction of the first blank 21 to prevent the outer box 12 from falling apart.

[0059] According to a preferred embodiment of the present utility model, when the second blank 22 is wound around the surface of the first structural layer 121, the position of the fragile part 211 in the first blank 21 is aligned with the side edge of the second blank 22. When opening the outer box 12, the second blank 22 is opened along the direction opposite to the winding direction with the side edge as the boundary. Correspondingly, the first structural layer 121 is disconnected at the position of the fragile part 211 of the first blank 21, so that the first structural layer 121 can be damaged along the side edge of the second blank 22, and the outer box 12 is opened.

[0060] Preferably, the sizes of the structural sheets in the first blank 21 and the second blank 22 can be adjusted so that the side edge of the second blank 22 is aligned with the folding traces and the boundary parts in the first blank 21, reducing the fragile part 211 in the first blank 21, or enabling the fragile part 211 to cover the folding traces, simplifying the processing process, and being beneficial to improving the structural strength of the first structural layer 121.

[0061] Specifically, as Figure 3 shown, the surface of the first blank 21 has a first crease line 212, and the first blank 21 is folded along the first crease line 212 and wound around the outer circumference of the inner box 11. The inner box 11 is generally in a shape similar to an apple, and the side surface of the apple shape includes multiple bent planes. For example, in the horizontal direction, it includes 8 side-by-side planes. The first blank 21 can be provided with 8 horizontally arranged and connected structural sheets, and a first crease line 212 is processed between each structural sheet. In the vertical direction, each structural sheet can be processed with four first crease lines 212 to form five bendable sub-structural sheets. Preferably, the sizes of the sub-structural sheets match the sizes of the corresponding structures in the inner box 11.

[0062] As Figure 4 shown, the surface of the second blank 22 has a second crease line 222, and the second blank 22 is folded along the second crease line 222 and wound around the outer circumference of the first structural layer 121. For example, one end of the second blank 22 is located at the top or bottom of the first structural layer 121 or the inner box 11 (in some embodiments, the first structural layer 121 does not completely cover the inner box 11), and is folded and wound along a preset direction. The position of the second crease line 222 is preferably corresponding to the edge of the first structural layer 121.

[0063] The side of the second blank 22 corresponds to the boundary in the first blank 21, the position of the first crease line 212, and the position of the weak part 211. When the outer box 12 needs to be opened, it is opened along the side edge of the second blank 22. At the same time, the first structural layer 121 separates along the side of the second blank 22. The first structural layer 121 can separate at the position of the boundary, the position of the first crease line 212, and the position of the weak part 211. The boundary refers to the side of each structural piece in the first blank 21 other than the side adjacent to the adjacent structural piece. Preferably, the weak part 211 covers all of the first crease lines 212. For example, Figure 3 as shown by the dashed lines in, the positions of the first crease lines 212 are all processed into discontinuous break lines.

[0064] In some embodiments, the shape and size of some structural pieces (the part surrounded by the side and the second crease line 222) in the second blank 22 can be set to be substantially the same as the shape and size of the sub-structural pieces (the part surrounded by the boundary and the first crease line 212) in the first blank 21, so that when the outer box 12 is opened along the side of the second blank 22, the first structural layer 121 can be damaged at the position of the first crease line 212, reducing the processing steps. The boundaries of another part of the structural pieces in the second blank 22, for example, Figure 2A and Figure 2B the diagonal lines 221 in, can be set to be aligned with the diagonals of the sub-structural pieces in the first blank 21. At the corresponding positions of the diagonal lines 221 in the first blank 21, weak parts 211 are arranged along the diagonals. At the position of the diagonal lines 221, the surrounding direction of the second blank 22 (which is also the direction of opening the outer box 12 along the side of the second blank 22) can be changed. Arranging the weak parts 211 along the diagonals can further reduce the weak parts 211 in the first blank 21. This embodiment can make the position of the first crease line 212 in the first blank 21 correspond to the position of the boundary of the second blank 22, so that the first crease line 212 can coincide with some of the weak parts 211, reducing the processing difficulty and improving the structural strength of the first structural layer 121.

[0065] In other embodiments, the shape and size of the structural pieces in the second blank 22 can also be set to be smaller than the shape and size of the sub-structural pieces in the first blank 21. For example, after the second blank 22 surrounds the first structural layer 121 for one week, two adjacent structural pieces with adjacent sides in the second blank 22 are coplanar and correspond to one side plane in the first structural layer 121. To ensure that the outer box 12 can be opened along the side of the second blank 22 when opening the outer box 12, weak parts 211 need to be processed on the first blank 21 corresponding to the side plane of the first structural layer 121. This embodiment is beneficial to improving the design freedom of the second blank 22 and enhancing the appearance performance ability of the outer box 12.

[0066] Such as Figure 5 andFigure 6 As shown, according to a preferred embodiment of the present utility model, the inner box 11 includes an upper cover 111 and a lower bottom 112. The upper cover 111 and the lower bottom 112 are snap-fitted together to jointly define a receiving space, and the commodity to be packaged can be placed in the receiving space. The upper cover 111 is arranged to be separable or rotatable relative to the lower bottom 112. For example, the upper cover 111 can be arranged as Figure 5 shown, separable relative to the lower bottom 112 to open the receiving space. In some other embodiments, the upper cover 111 can be arranged to be rotatable relative to the lower bottom 112, for example, flipped towards one side to open the receiving space.

[0067] In some preferred embodiments, a limiting structure can also be provided inside the receiving space to snap-fit the commodity to be packaged in the receiving space, restrict the shaking of the commodity in the receiving space, and protect the commodity and the packaging structure 1. The limiting structure can be made of a flexible cushioning material, or can be made of a material with a certain hardness or stiffness according to the shape and size of the commodity to be packaged.

[0068] According to some embodiments, the inner box 11 is made by folding a blank. For example, Figure 7 the blank 23 shown can be folded into the inner box 11. The blank 23 can be as Figure 7 shown, including a plurality of split structures, and can be fixed by pasting, plugging or snap-fitting after being folded and formed. Preferably, the blank 23 also includes a structure for strengthening the structural strength of the inner box 11. For example, the inner box 11 is made by folding and pasting a double-layer blank 23 at some positions.

[0069] In some embodiments of the present utility model, the upper cover 111 and the lower bottom 112 are fixed by plugging, and the inner box 11 further includes a connecting member 113. The connecting member 113 is fixedly arranged on the inner circumferential direction of the upper cover 111 and is in interference plug connection with the inner circumferential direction of the lower bottom 112. Or in some other embodiments, as Figure 5 and Figure 6 shown, the connecting member 113 is fixedly arranged on the inner circumferential direction of the lower bottom 112, and the connecting member 113 is in interference plug connection with the inner circumferential direction of the upper cover 111. Specifically, the connecting member 113 can also be made by folding the blank 23. The connecting member 113 is pasted on the inner circumferential direction of the lower bottom 112 and extends to a position higher than the upper edge of the lower bottom 112. The upper cover 111 can be plugged with the connecting member 113, and the outer diameter of the circumferential direction of the connecting member 113 is slightly larger than the inner diameter of the circumferential direction of the upper cover 111 to improve the bonding strength between the connecting member 113 and the upper cover 111. In this embodiment, the provision of the connecting member 113 can connect the upper cover 111 and the lower bottom 112, and make the outer circumferential directions of the upper cover 111 and the lower bottom 112 roughly aligned, preventing steps from appearing on the outer surface of the inner box 11.

[0070] Finally, it should be noted that the above are only embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
