[0012] The specific embodiments of the present utility model are described in conjunction with the above-mentioned drawings.

[0013] Depend on Figures 1 to 3It can be seen that the multi-layer tower-shaped food packaging box of the utility model is formed by folding a single piece of paperboard, and includes at least one bottom plate 10, a first trapezoidal enclosure 20 is extended from one side of the bottom plate 10, a first indentation 21 is pressed between the bottom plate 10 and the first enclosure 20, a second enclosure 30 and a third enclosure 40 having the same shape as the first enclosure 20 are sequentially extended along one side of the first enclosure 20, a vertical indentation 22 is pressed between the first enclosure 20, the second enclosure 30 and the third enclosure 40, and a vertical indentation 22 is pressed between the first enclosure 20, the second enclosure 30 and the third enclosure 40. The enclosure 40 is respectively pressed with a second horizontal indentation 23, a third indentation 24, a fourth indentation 25 and a fifth indentation 26. The first enclosure 20, the second enclosure 30 and the third enclosure 40 are folded inward to form a tower-shaped packaging space. The bottom plate 10 is folded along the first indentation 21 to form the bottom of the packaging space. The first indentation 21, the second indentation 23 and the third indentation 24 are folded inward to form a first unit layer of the packaging space. The third indentation 24, the fourth indentation 25 and the fifth indentation 26 are folded inward to form a second unit layer located above the first unit layer. In this solution, the above-mentioned enclosures are folded inward to form a cavity, and the food (candy) is placed in the cavity. The bottom plate is folded upward to form the bottom. A single enclosure is folded along the indentation to form a plurality of overlapping unit layers, forming a multi-layer tower-like structure.

[0014] Depend on Figure 2 It can be seen that a card insertion plate 31 is extended from the corresponding edges where the second and third enclosures 30 and 40 are connected to the base plate 10, and an inner buckle plate 11 is extended from the corresponding edges where the base plate 10 and the second and third enclosures 30 and 40 are connected. An indentation is provided between the base plate 10 and the inner buckle plate 11, and a socket 12 corresponding to the position of the card insertion plate 31 is provided at the indentation. In this solution, after the second and third enclosures 30 and 40 are folded inward, the card insertion plate 31 is inserted into the socket 12 to form a stable structure between the second and third enclosures 30 and 40 and the base plate 10 to prevent the bottom from falling off.

[0015] Depend on Figure 1 It can be seen that a plurality of diamond-shaped openings 32 are provided between the first enclosure 20, the second enclosure 30 and the third enclosure 40, and each of the diamond-shaped openings 32 is arranged between two adjacent unit layers, and its four corners are respectively connected to the second indentation 23, the third indentation 24 and the fourth indentation 25. In this scheme, only the first and second unit layers are taken as examples, and the other unit layers are also analogized in the same manner as in this scheme. When each enclosure is folded inward along the second indentation 23, the diamond-shaped openings 32 form an avoidance structure to prevent overlapping of adjacent panels during folding, which affects the forming and stability of the packaging structure.

[0016] Depend on Figure 1It can be seen that the free side edge of the first enclosure 20 extends from the bonding sheet 27, and an indentation is pressed between the first enclosure 20 and the bonding sheet 27. After the first enclosure 20, the second enclosure 30 and the third enclosure 40 are enclosed, the bonding sheet 27 is adhered and fixed to the third enclosure 40. After the above-mentioned enclosures are enclosed to form a closed packaging space, the bonding sheet 27 is used to connect and fix two adjacent non-connected enclosures, and can be fixed by gluing or binding.

[0017] Depend on Figure 1 As can be seen, the top edges of the first enclosure 20, the second enclosure 30 and the third enclosure 40 extend triangular capping pieces 28, respectively, and through holes 281 are provided near the top corners of the capping pieces 28. In this solution, the capping pieces 28 of each enclosure form the spire after folding, which not only closes the upper opening, but also forms a spire shape, making the packaging more concrete. The rope is passed through the through holes 281 and then knotted, which is convenient for hand-carrying and makes the seal more secure. In order to make it more convenient to display or hang the goods, a hanging ear 13 is extended from one side of the bottom base plate 10.

[0018] Depend on Figure 1 It can be seen that the food packaging box of the utility model can be designed as a polygon, and an additional panel 50 with the same structure as the first panel 20 is arranged between the first panel 20 and the second panel 30 or the second panel 30 and the third panel 40. The number of the additional panels 50 plus the first panel 20, the second panel 30 and the third panel 40 is the same as the number of sides of the polygon. For example, when it is designed as a hexagonal pagoda, three additional panels can be added, and after adding the above-mentioned first to third panels, there are six panels corresponding to the hexagon.

[0019] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
