[0037] In addition, the technical features involved in the different embodiments of the utility model described above can be combined with each other as long as they do not conflict with each other.

[0038] The utility model provides Figures 1 to 5 As shown in the figure, a tea cake packaging box that can be quickly folded and formed is intended to solve the disadvantage that the existing tea cake packaging box has many assembly steps.

[0039] The tea cake packaging box that can be quickly folded and formed mainly includes: a packaging box body 100 and a sleeve 200, the sleeve 200 is sleeved on the packaging box body 100, and the packaging box body 100 has an unfolded state and a folded state. When the packaging box body 100 is in the unfolded state, the packaging box body 100 is a paperboard; when the packaging box body 100 is in the folded state, the packaging box body 100 can accommodate the tea cake so that the tea cake is tightly and safely wrapped in the packaging box body 100. At this time, the sleeve 200 is sleeved on the packaging box body 100, and the friction between the two is used to fix the packaging box body 100, so that the packaging box body 100 will not unfold by itself.

[0040] The packaging box body 100 includes an inner folding piece 110 and an outer folding piece 120. One end of the middle part of the inner folding piece 110 is connected to the outer folding piece 120 by cutting to form a connecting portion 114. Specifically, the inner folding piece 110 and the outer folding piece 120 are both cut from a piece of cardboard. The inner folding piece 110 and the outer folding piece 120 are not completely cut during the cutting process, but a part is left to form the connecting portion 114, so that the connecting portion 114 is respectively connected to the inner folding piece 110 and the outer folding piece 120.

[0041] The packaging box body 100 has an unfolded state and a folded state:

[0042] When the packaging box body 100 is in the unfolded state, the inner folding member 110, the outer folding member 120 and the connecting portion 114 are located on the same plane, that is, in the form of a piece of cardboard, and the outer folding member 120 and the inner folding member 110 are parallel to each other and arranged side by side;

[0043] When the packaging box body 100 is in a folded state, both ends of the inner folding member 110 and both ends of the outer folding member 120 are bent in the same direction and form an annular structure respectively. Specifically, since the outer folding member 120 and the inner folding member 110 are parallel to each other and arranged side by side, when the inner folding member 110 and the outer folding member 120 both form an annular structure, a cavity with two ends opening is formed on the inner folding member 110 and the outer folding member 120, and the directions of the two ends opening of the inner folding member 110 and the outer folding member 120 are the same. The outer folding member 120 is sleeved on the inner folding member 110, and the inner folding member 110 is arranged in the cavity of the outer folding member 120, and the outer folding member 120 and the inner folding member 110 are arranged perpendicular to each other. Specifically, since the cavity of the outer folding member 120 and the cavity of the inner folding member 110 both have two openings facing the same direction, when the outer folding member 120 and the inner folding member 110 are arranged perpendicular to each other, the two openings of the inner folding member 110 are covered by the outer folding member 120, so that a storage space is formed between the outer folding member 120 and the inner folding member 110, and the storage space is used to store tea cakes. Specifically, the width of the outer folding member 120 in the opening direction is greater than the width of the inner folding member 110 in the opening direction, so that the two openings of the inner folding member 110 can be completely covered by the outer folding member 120, thereby enhancing the airtightness.

[0044] Existing tea cake packaging technology mostly uses metal boxes or paper boxes. Metal boxes are expensive, while paper boxes are usually produced by pulp pressing, gluing, folding, or folding and then gluing. The production methods of pulp pressing, gluing, or folding and then gluing are relatively complex, costly, and not environmentally friendly. For example, the patent with publication number: CN204368581U discloses a non-adhesive buffer tea cake packaging box, which is inserted into the lock box through the lock buckle on the lid after multiple folding to become a buffer tea cake packaging box. Although the use of glue is avoided, it has many assembly steps and the utilization rate of the cardboard is low due to the uneven edge of the cardboard.

[0045] The utility model adopts a paper forming structure, and the inner folding piece 110 and the outer folding piece 120 are connected by the connecting part 114 so that the packaging box body 100 has an unfolded state and a folded state. During the assembly process, the inner folding piece 110 is rotated to a stacked state perpendicular to the outer folding piece 120, and the tea cake can be placed on the inner folding piece 110, and then the inner folding piece 110 and the outer folding piece 120 are bent in sequence to form the packaging box body 100 into a folded state that is convenient for inserting into the envelope 200 and fixing. Compared with the existing tea cake box, it has the advantages of simple assembly and high cardboard utilization rate.

[0046] In some embodiments, Figures 1 to 5As shown in the figure, the inner folding member 110 includes: an inner bottom plate 111, two inner top plates 112, and two inner side plates 113. When both ends of the inner folding member 110 are bent in the same direction and form a ring structure, the two inner top plates 112 overlap so that the inner bottom plate 111, the two inner top plates 112, and the two inner side plates 113 form a rectangular structure. Specifically, by adjusting the size of the two inner side plates 113, the inner bottom plate 111 and the two inner top plates 112 when the inner folding member 110 forms a ring structure are parallel to each other.

[0047] The inner bottom plate 111 is disposed between the two inner top plates 112 , and the two inner side plates 113 are respectively connected between the inner bottom plate 111 and the two inner top plates 112 .

[0048] The outer folding member 120 includes an outer bottom plate 121, two outer top plates 122, and two outer side plates 123. When both ends of the outer folding member 120 are bent in the same direction and form an annular structure, the two outer top plates 122 overlap so that the outer bottom plate 121, the two outer top plates 122, and the two outer side plates 123 form a rectangular structure. Specifically, the sizes of the two outer side plates 123 can be adjusted so that the outer bottom plate 121 and the two outer top plates 122 are parallel to each other when the outer folding member 120 forms an annular structure.

[0049] The outer bottom plate 121 is disposed between the two outer top plates 122 , and the two outer side plates 123 are respectively connected between the outer bottom plate 121 and the two outer top plates 122 .

[0050] When the packaging box body 100 is in the unfolded state, the outer bottom plate 121 and the inner bottom plate 111 are arranged side by side, and the end of the inner bottom plate 111 facing the outer bottom forms a connecting portion 114 connected to the inner bottom plate 111. Specifically, a folding mark can be embossed on the connecting portion 114 so that the packaging box body 100 can be easily transformed between the unfolded state and the folded state.

[0051] In some embodiments, Figures 2 to 5 As shown in , when the packaging box body 100 is in the unfolded state, the two inner side plates 113 are located at the two ends of the inner bottom plate 111 in the X-axis direction, the two outer side plates 123 are located at the two ends of the outer bottom plate 121 in the X-axis direction, the inner bottom plate 111 and the outer bottom plate 121 are arranged side by side in the Y-axis direction, and the X-axis direction is perpendicular to the Y-axis direction;

[0052] The shape of the connecting portion 114 is polygonal, and an outer linear fold 114a is provided at the connecting portion 114 of the connecting portion 114 and the outer bottom plate 121, and the outer linear fold 114a is parallel to the X-axis direction. Specifically, the outer bottom plate 121 is rectangular. An inner linear fold 114b is provided at the connecting portion 114 of the connecting portion 114 and the inner bottom plate 111, and the angle between the inner linear fold 114b and the outer linear fold 114a is 45 degrees.

[0053] When the packaging box body 100 is in the unfolded state, the inner bottom plate 111 and the outer bottom plate 121 are oriented in the same direction. In the actual assembly process, there are the following two assembly methods:

[0054] 1. First, the inner bottom plate 111 can be folded along the outer straight fold 114a in the direction of the inner bottom plate 111 toward the outer bottom plate 121, so that the inner bottom plate 111 and the outer bottom plate 121 overlap, and at this time, the inner bottom plate 111 and the outer bottom plate 121 face each other; then, the inner bottom plate 111 is folded along the inner straight fold 114b in the direction away from the outer bottom plate 121, so that the inner bottom plate 111 and the outer bottom plate 121 face each other in the same direction; finally, the tea cake is placed on the inner bottom plate 111, and then the two ends of the inner bottom plate 111 (inner top plate 112) and the two ends of the outer bottom plate 121 (outer top plate 122) are brought together and overlapped in the middle, so that the packaging box body 100 is in a folded state, and at this time, the packaging box body 100 is covered by the envelope 200, and the friction between the two is fixed to form, and the packaging is completed, so that the packaging box body 100 will not unfold by itself;

[0055] 2. When cutting the cardboard, the inner straight fold 114b and the outer straight fold 114a are imprinted on the cardboard. During the assembly process, the inner bottom plate 111 can be directly rotated so that the inner bottom plate 111 is perpendicular to the outer bottom plate 121. During this period, the connecting portion 114 can be moved according to the form of method 1. At this time, the tea cake can be placed on the inner bottom plate 111, and then the two ends of the inner bottom plate 111 (inner top plate 112) and the two ends of the outer bottom plate 121 (outer top plate 122) are successively brought together and overlapped in the middle, so that the packaging box body 100 is in a folded state. At this time, the packaging box body 100 is covered by the envelope 200, and the friction between the two is fixed to form, and the packaging is completed, so that the packaging box body 100 will not unfold by itself.

[0056] In some embodiments, Figures 2 to 5 As shown in the figure, the connecting portion 114 has a first edge 114c between one end of the inner linear fold 114b facing the inner side plate 113 and the outer linear fold 114a, and the angle between the straight line formed by the two ends of the first edge 114c and the inner linear fold 114b is not greater than 90 degrees.

[0057] When the packaging box body 100 is in a folded state, the connecting portion 114 is located between the inner bottom plate 111 and the outer bottom plate 121, and a "Z" shape is formed between the inner bottom plate 111, the connecting portion 114, and the outer bottom plate 121, which can act as a spring to a certain extent, provide a larger buffer space for the tea cake, and better protect the tea cake. Preferably, the angle between the straight line formed by the two ends of the first edge 114c and the inner straight line fold 114b is 90 degrees, so that the volume of the connecting portion 114 is larger, and the lengths of the outer straight line fold 114a and the inner straight line fold 114b are longer, so that the connecting portion 114 can provide greater elastic force to the inner bottom plate 111 and the outer bottom plate 121.

[0058] In some embodiments, Figures 2 to 5 As shown in , the connecting portion 114 has a second edge 114d between one end of the inner linear fold 114b facing the outer side plate 123 and the outer linear fold 114a, and the second edge 114d is perpendicular to the outer linear fold 114a. By providing the second edge 114d, when the packaging box body 100 is in a folded state, the portion of the inner bottom plate 111 close to the outer linear fold 114a will not intersect with the outer linear fold 114a. When the area of ​​the inner bottom plate 111 is smaller than that of the outer bottom plate 121, since the portion of the inner bottom plate 111 close to the outer linear fold 114a will not intersect with the outer linear fold 114a, the inner bottom plate 111 can be closer to the middle of the outer bottom plate 121 or the symmetry center of the inner bottom plate 111 overlaps with the symmetry center of the outer bottom plate 121, and the packaging is more regular.

[0059] Preferably, the size of the inner bottom plate 111 is 200mm*200mm (length in the Y-axis direction*length in the X-axis direction, the same format applies hereinafter), the size of the outer bottom plate 121 is 216mm*206mm, the length of the outer straight fold 114a is 180mm, and the length of the second edge 114d is 10mm.

[0060] In some embodiments, Figures 2 to 5 As shown in , when the packaging box body 100 is in the unfolded state, the connecting portion 114 forms a rectangular structure with the inner bottom plate 111. Specifically, the inner folding piece 110 and the outer folding piece 120 are each cut from a piece of cardboard, and the inner folding piece 110 and the outer folding piece 120 are not completely cut during the cutting process, but a portion is left to form the connecting portion 114, so that the connecting portion 114 is connected to the inner folding piece 110 and the outer folding piece 120 respectively.

[0061] In some embodiments, Figure 5 As shown in , the first edge 114c is a curve or a fold line. Specifically, the non-straight line of the first edge 114c does not affect its own function, and the first edge 114c can be an arc, a fold line, a wavy line, or a decorative lace, a trademark, etc., and is used to place tools and other practical functions.

[0062] In some embodiments, Figure 1 to Figure 2 As shown in the figure, the envelope 200 is sleeved on the outer folding member 120, and a decorative window 210 is provided through the envelope 200, and the decorative window 210 is provided corresponding to the outer top plate 122. Preferably, the outer top plate 122 is provided with a decorative area (not shown in the figure) corresponding to the decorative window 210. The decorative area can be observed through the decorative window 210, which increases practicality.

[0063] In summary, a tea cake packaging box that can be quickly folded and formed is provided, including a packaging box body and an envelope, the packaging box body includes an inner folding piece and an outer folding piece, one end of the middle part of the inner folding piece is cut to form a connecting portion connected to the outer folding piece, and the packaging box body has an unfolded state in which the outer folding piece and the inner folding piece are parallel to each other and side by side, and a folded state in which the outer folding piece is sleeved on the inner folding piece and perpendicular to each other. The utility model adopts a one-paper forming structure, and connects the inner folding piece and the outer folding piece through a connecting portion so that the packaging box body has an unfolded state and a folded state. During the assembly process, the inner folding piece is rotated to a stacking state perpendicular to the outer folding piece, and the tea cake can be placed on the inner folding piece, and then the inner folding piece and the outer folding piece are bent in sequence to form a folded state in which the packaging box body is conveniently inserted into the envelope and fixed. Compared with the existing tea cake box, it has the advantages of simple assembly and high cardboard utilization rate.

[0064] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
