Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically to a novel packaging box and cardboard structure. Background Technology

[0002] Birthday cakes are an essential part of birthday celebrations for modern people. Cakes are usually packaged in cake boxes and given as gifts to friends or relatives. When purchasing a cake, the server needs to pack the prepared cake in a cake box to prevent it from being contaminated by dust or scratched during transportation.

[0003] A search revealed a cake packaging box published in China on June 9, 2019, with patent publication number CN210113205U. The box is described as including a bottom and a lid. The lid is composed of a main cardboard and four side cardboards (part 1, part 2, part 3, and part 4) respectively located on the four sides of the main cardboard. Side cardboard 1 has symmetrical adhesive cardboard on both its left and right sides. Each adhesive cardboard has a fold line along its diagonal dividing it into a first adhesive cardboard and a second adhesive cardboard. Side cardboard 4 is located between the first adhesive cardboard on the left side of side cardboard 1 and the first adhesive cardboard on the left side of side cardboard 3. Side cardboard 1 and side cardboard 3 have the same structure, as do side cardboard 2 and side cardboard 4, which are symmetrical about the main cardboard. A double-sided adhesive strip is provided at each of the four corners of the inner walls of side cardboard 2 and side cardboard 4.

[0004] While the aforementioned existing technical solutions reduce the space occupied by the packaging boxes during storage, making it easier for stores to store them, the device uses pre-set double-sided adhesive for assembly. When the box lid is stored for a long time or the storage method is not appropriate, the double-sided adhesive is prone to failure, making it inconvenient to assemble the packaging boxes. Furthermore, after packaging, additional packaging straps are required to tie the boxes for easy handling, which is a very troublesome process and reduces work efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a novel packaging box and cardboard structure to solve the problems mentioned in the background art. The device uses a pre-set double-sided adhesive for assembly, which can easily cause the double-sided adhesive to fail when the box lid is stored for a long time or improperly, making it inconvenient to assemble the packaging box. Furthermore, after packaging, additional packaging straps are required for binding to facilitate handling, which is a very troublesome process and reduces work efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a novel packaging box and cardboard structure, including a base and a top cover. A placement seat is fixedly connected to the top of the base. Two corresponding first side cardboards and two corresponding second side cardboards are fixedly connected to the four sides of the top cover, respectively. Pre-set creases are provided between the first side cardboards and the second side cardboards and the top cover. Two cardboard pockets are fixedly connected to one end of each of the two second side cardboards. Two cooperating connecting cardboards are connected to the sides of each of the two first side cardboards. Pre-set creases are provided between the connecting cardboards and the first side cardboards. Each of the four connecting cardboards has a barbed cardboard that cooperates with the cardboard pockets.

[0009] By adopting the above technical solution, the two second-side cardboards are bent at 90 degrees, so that the second-side cardboards and the top cover form a right angle. The four connecting cardboards are bent at 90 degrees, so that the connecting cardboards and the first-side cardboards are bent at 90 degrees. Then, one of the first-side cardboards is bent more than 90 degrees. The first-side cardboard drives the connecting cardboard and the hook cardboard to move, so that the position of the hook cardboard exceeds the cardboard pocket, and then the first-side cardboard rotates, so that the two hook cardboards are inserted into the cardboard pocket. Then, the above steps are repeated for the other first-side cardboard, so that the top cover, the two first-side cardboards and the two second-side cardboards cooperate to form a frame. At this time, the frame is inverted on the base, so that the placement seat is located inside the frame. The placement seat is used to place the cake, so that the assembly efficiency of the packaging box will not be reduced after long-term storage, thereby achieving the purpose of facilitating the packaging of the box.

[0010] Optionally, the base is rotatably connected to four cooperating rotary knobs, and two mutually spaced plastic handles are fixedly connected to the four rotary knobs.

[0011] By adopting the above technical solution, rotating the plastic handles allows them to unfold to both sides, making it easier to place the cake on the stand and the top cover on the base. Once the top cover is on the base, rotating the two plastic handles brings them closer together at the top of the top cover, making it easier for people to lift the packaging box without having to use additional packaging straps to tie it, thus improving work efficiency.

[0012] Optionally, both of the plastic handles are provided with a hand pad.

[0013] By adopting the above technical solution, the hand pad is used to improve the comfort of the hands when people hold the plastic handle.

[0014] Optionally, the top of the base is fixedly connected with four matching slots, and paper inserts are fixedly connected to the two first side cardboards and the two second side cardboards.

[0015] By adopting the above technical solution, when assembling the packaging box, four paper inserts are inserted into four slots respectively. The slots squeeze and position the paper inserts, thereby reducing the probability of the first and second side cardboards detaching from the base, thus improving the stability of the equipment.

[0016] Optionally, each of the two first side panels has an observation slot, and a transparent sheet is provided on the observation slot.

[0017] By adopting the above technical solution, the observation slot and the transparent sheet are used to facilitate personnel to observe the situation inside the packaging box, making it easier to observe whether the cake is damaged, and improving the appearance of the packaging box.

[0018] Optionally, the four corners of the bottom of the base are provided with anti-slip corner protectors.

[0019] By adopting the above technical solution, the anti-slip corner protectors are used to increase the friction between the base and the table when the packaging box is placed on the table, thereby improving the stability of the equipment.

[0020] (III) Beneficial Effects

[0021] In summary, this utility model has at least one of the following beneficial technical effects:

[0022] 1. This novel packaging box and cardboard structure involves bending two second-side cardboards at 90 degrees, creating a right angle between the second-side cardboards and the top cover. Four connecting cardboards are then bent at 90 degrees, causing the connecting cardboards to bend at 90 degrees with the first-side cardboard. One first-side cardboard is then bent beyond 90 degrees, causing the connecting cardboard and the hook cardboard to move, so that the hook cardboard extends beyond the cardboard pocket. This causes the first-side cardboard to rotate, allowing the two hook cardboards to be inserted into the cardboard pocket. The above steps are repeated for the other first-side cardboard, resulting in the top cover, two first-side cardboards, and two second-side cardboards working together to form a frame. This frame is then placed upside down on the base, with the placement seat located inside the frame. This design ensures that the assembly efficiency of the packaging box is not reduced after long-term storage, thus facilitating packaging.

[0023] 2. This new type of packaging box and cardboard structure allows the plastic handles to be rotated and unfolded to both sides, making it easier to place the cake on the base and the top cover on the bottom. After the top cover is placed on the bottom, rotating the two plastic handles brings them closer together at the top of the top cover, making it easier for people to lift the packaging box without having to use additional packaging straps to tie it, thus improving work efficiency.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] Reference Figures 1-5A novel packaging box and cardboard structure includes a base 1 and a top cover 2. A placement seat 3 is fixedly connected to the top of the base 1. Two corresponding first side cardboard 4s and two corresponding second side cardboard 5s are fixedly connected to the four sides of the top cover 2, respectively. Pre-set creases are provided between the first side cardboard 4s and the second side cardboard 5s and the top cover 2. Two cardboard pockets 6 are fixedly connected to one corresponding end of each of the two second side cardboard 5s. Two cooperating connecting cardboard 7s are connected to the sides of each of the two first side cardboard 4s. Pre-set creases are provided between the connecting cardboard 7s and the first side cardboard 4s. Each of the four connecting cardboard 7s has a barbed cardboard 8 that cooperates with the cardboard pockets 6. The two second side cardboard 5s are bent at 90 degrees, forming a right angle between the second side cardboard 5s and the top cover 2. The four connecting cardboard 7s are then... The board 7 is bent at a 90-degree angle, causing the connecting cardboard 7 and the first side cardboard 4 to bend at a 90-degree angle. Then, one of the first side cardboard 4 is bent more than 90 degrees. The first side cardboard 4 drives the connecting cardboard 7 and the hook cardboard 8 to move, so that the position of the hook cardboard 8 exceeds the cardboard pocket 6, and then the first side cardboard 4 rotates, so that the two hook cardboard 8 are inserted into the cardboard pocket 6. Then, the above steps are repeated for the other first side cardboard 4, so that the top cover 2, the two first side cardboard 4 and the two second side cardboard 5 cooperate to form a frame. At this time, the frame is inverted on the base 1, so that the placement seat 3 is located inside the frame. The placement seat 3 is used to place the cake, so that the assembly efficiency of the packaging box will not be reduced after long-term storage, thereby facilitating the packaging of the box.

[0034] Example 2

[0035] Reference Figure 1 and Figure 2 The base 1 is rotatably connected to four cooperating rotary knobs 9. Two plastic handles 10 are fixedly connected to the four rotary knobs 9. Rotating the plastic handles 10 causes them to unfold to both sides, making it easier to place the cake on the placement seat 3 and the top cover 2 on the base 1. After the top cover 2 is placed on the base 1, rotating the two plastic handles 10 causes them to come closer together at the top of the top cover 2, making it easier for people to lift the packaging box without having to use additional packaging straps to tie the packaging box, thus improving work efficiency.

[0036] Reference Figure 1 Both plastic handles 10 are equipped with hand pads 11, which are used to improve the comfort of the hands when people hold the plastic handles 10.

[0037] Reference Figure 2 and Figure 3The top of the base 1 is fixedly connected with four matching slots 12. Paper inserts 13 are fixedly connected to the two first side cardboards 4 and the two second side cardboards 5. When assembling the packaging box, the four paper inserts 13 are inserted into the four slots 12 respectively. The slots 12 squeeze and position the paper inserts 13, thereby reducing the probability of the first side cardboards 4 and the second side cardboards 5 detaching from the base 1, thereby improving the stability of the equipment.

[0038] Reference Figure 1 and Figure 5 Both first side cardboard 4 have observation slots, and transparent sheets 14 are provided on the observation slots. The observation slots and transparent sheets 14 are used to facilitate personnel to observe the situation inside the packaging box, to facilitate observation of whether the cake is damaged, and to improve the appearance of the packaging box.

[0039] Reference Figure 1 The four corners of the bottom of the base 1 are provided with anti-slip corner protectors 15. The anti-slip corner protectors 15 are used to increase the friction between the base 1 and the table when the packaging box is placed on the table, thereby improving the stability of the equipment.

[0040] In summary, the working principle and process of this new packaging box and cardboard structure are as follows: First, bend the two second-side cardboard pieces 5 at 90 degrees, forming a right angle between them and the top cover 2. Then, bend the four connecting cardboard pieces 7 at 90 degrees, so that the connecting cardboard pieces 7 and the first-side cardboard pieces 4 are bent at 90 degrees. Next, bend one of the first-side cardboard pieces 4 more than 90 degrees. This causes the first-side cardboard piece 4 to move the connecting cardboard pieces 7 and the hooked cardboard pieces 8, so that the hooked cardboard pieces 8 are positioned beyond the cardboard pocket 6. This causes the first-side cardboard piece 4 to rotate, allowing the two hooked cardboard pieces 8 to insert into the cardboard pocket 6. The above steps are then repeated for the other first-side cardboard piece 4, so that the top cover 2, the two first-side cardboard pieces 4, and the two second-side cardboard pieces 5 cooperate to form a frame. The frame is then inverted onto the base 1, with the placement seat 3 located inside the frame. The placement seat 3 is used to place the cake, ensuring that the assembly efficiency of the packaging box is not reduced after long-term storage, thus facilitating packaging. The plastic handle 10 is then rotated to both sides... The box is unfolded to facilitate placing the cake on the base 3 and the top cover 2 on the base 1. After the top cover 2 is placed on the base 1, the two plastic handles 10 are rotated so that they are close together at the top of the top cover 2, making it easier for personnel to lift the box and avoiding the need for additional packaging straps, thus improving work efficiency. The hand pad 11 is used to improve the comfort of the hands when personnel hold the plastic handles 10. When assembling the box, the four paper inserts 13 are inserted into the four slots 12 respectively. The slots 12 squeeze and position the paper inserts 13, thereby reducing the probability of the first side cardboard 4 and the second side cardboard 5 detaching from the base 1, thus improving the stability of the equipment. The observation slot works with the transparent sheet 14 to facilitate personnel to observe the contents of the box, making it easy to check if the cake is damaged and improving the appearance of the box. The anti-slip corner protectors 15 are used to increase the friction between the base 1 and the table when the box is placed on the table, thereby improving the stability of the equipment.

[0041] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
