Technical Field
[0001] This utility model relates to the field of fan-shaped paper boxes, specifically a fan-shaped paper box. Background Technology
[0002] Paper box packaging largely uses its exquisite design and decoration to promote and beautify products, thereby enhancing their competitiveness. Since the shape and structural design of paper boxes are often determined by the shape and characteristics of the packaged goods, there are many styles and types, including rectangular, square, polygonal, irregularly shaped, and cylindrical boxes. However, their manufacturing processes are basically the same: material selection – design – template manufacturing – stamping – assembly into a box.
[0003] For example, the authorized patent with publication number CN222496959U (Fan-shaped Paper Box and its Folding Sheet): its structure includes a fan-shaped box body and a cover plate. The fan-shaped box body has a receiving space. The cover plate is located at the opening of the fan-shaped box body and is connected to at least a part of the fan-shaped box body to close the opening of the receiving space. There is one or two cover plates. The fan-shaped box body is composed of a left side piece, a fan-shaped piece, and a right side piece to form a receiving space. When the folding sheet is operated to form a fan-shaped paper box, the two fan-shaped pieces are folded to the front and back of the left side piece respectively, and the right side piece is folded to the opposite side of the left side piece. With the adhesive piece glued and positioned, the fan-shaped box body is formed. After food is loaded, the cover plate and the fan-shaped box body are doubly sealed and positioned. The fan-shaped box body fits the small-volume food better and prevents the food from shaking. The double positioning structure can effectively prevent the food from opening the cover plate during transportation. It is also convenient to load and unload. The V-shaped base structure attracts consumers and is easy to hold. The fan-shaped paper box is formed in one piece, which is convenient for users to form in one go and is easy to operate.
[0004] The opening and closing control of the existing fan-shaped cardboard box is not convenient enough, and the inside of the cardboard box is not easy to classify and store, the partitions are not obvious, the sides are easy to deform, and the compression protection is not strong enough. Summary of the Invention
[0005] The purpose of this utility model is to provide a fan-shaped paper box to solve the problems mentioned in the background art, such as inconvenient opening and closing control of the fan-shaped paper box, inconvenience for classifying and storing the contents, unclear partitioning, easy deformation of the sides, and insufficient resistance to compression.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a fan-shaped paper box, comprising a box body, a first fan-shaped cover, a second fan-shaped cover, a first storage slot and a second storage slot, wherein the box body is provided with a first storage slot and a second storage slot, the top of the first storage slot and the second storage slot are provided with a first fan-shaped cover and a second fan-shaped cover, and the sides of the box body are provided with a retaining edge.
[0007] In a further embodiment, the first storage tank is provided with a first partition and a second partition that cross each other, and the first storage tank and the second storage tank are separated by a third partition.
[0008] In a further embodiment, both the first and second sector covers are provided with creases, and both the first and second sector covers can be folded towards the edge end through the creases.
[0009] In a further embodiment, the inner sides of both the first and second sector covers are provided with latches and slots, and the latches and slots are staggered and spliced together.
[0010] In a further embodiment, both the first and second sector-shaped covers are made of paper, and both the first and second sector-shaped covers have a waterproof membrane on their outer sides.
[0011] In a further embodiment, the box body and the edge are designed as an integral structure, and the box body and the edge are fan-shaped.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The box of this utility model has a first storage slot and a second storage slot inside, and the first storage slot and the second storage slot are separated by a third partition. Inside the first storage slot, the first partition and the second partition are separated from each other. The first storage slot and the second storage slot are separated into multiple areas to facilitate the storage of different kinds of items.
[0014] The top of the box body of this utility model is provided with a first sector-shaped cover and a second sector-shaped cover, and both the first sector-shaped cover and the second sector-shaped cover can be closed. This design facilitates the opening and closing of the first sector-shaped cover and the second sector-shaped cover. The inner sides of the first sector-shaped cover and the second sector-shaped cover are provided with a latch and a slot, which facilitates the docking of the first sector-shaped cover and the second sector-shaped cover after they are closed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figure 1-5 The present invention provides an embodiment of a fan-shaped cardboard box, comprising a box body 1, a first fan-shaped cover 2, a second fan-shaped cover 3, a first storage slot 6, and a second storage slot 9. The box body 1 is provided with the first storage slot 6 and the second storage slot 9. The top of the first storage slot 6 and the second storage slot 9 is provided with the first fan-shaped cover 2 and the second fan-shaped cover 3. The sides of the box body 1 are provided with a retaining edge 4. The first storage slot 6 and the second storage slot 9 are used to store items. The first fan-shaped cover 2 and the second fan-shaped cover 3 are used to seal the first storage slot 6 and the second storage slot 9. The retaining edge 4 can protect the sides of the box body 1.
[0023] The first storage tank 6 is provided with a first partition 5 and a second partition 7 that intersect each other. The first storage tank 6 and the second storage tank 9 are separated by a third partition 8. The first storage tank 6 can be divided into multiple storage areas by the first partition 5 and the second partition 7, and the first storage tank 6 and the second storage tank 9 can be separated by the third partition 8.
[0024] Both the first sector-shaped cover 2 and the second sector-shaped cover 3 have creases, and both can be folded towards the end of the retaining edge 4 through the creases, making it easy to fold. The inner sides of both the first sector-shaped cover 2 and the second sector-shaped cover 3 are provided with latches 10 and slots 11, and the latches 10 and slots 11 are interlocked and combined. Both the first sector-shaped cover 2 and the second sector-shaped cover 3 are made of paper, and the outer sides of both are provided with waterproof membranes, which make the first sector-shaped cover 2 and the second sector-shaped cover 3 waterproof.
[0025] The box body 1 and the side guard 4 are designed as an integral structure, and the box body 1 and the side guard 4 form a fan-shaped structure. The side guard 4 can provide side protection for the box body 1.
[0026] Working principle: During use, the first storage slot 6 and the second storage slot 9 inside the box body 1 are sealed by the first sector-shaped cover 2 and the second sector-shaped cover 3. The first storage slot 6 and the second storage slot 9 are separated by the first partition 5 and the third partition 8, which can improve the storage diversity. The first sector-shaped cover 2 and the second sector-shaped cover 3 can be interlocked and assembled by the symmetrical latches 10 and latches 11 on the first sector-shaped cover 2 and the second sector-shaped cover 3, so that the first sector-shaped cover 2 and the second sector-shaped cover 3 can be closed and connected. The latches 10 can be used to manually pull and control the first sector-shaped cover 2 and the second sector-shaped cover 3. The side guards 4 can protect the sides of the box body 1 from impact.
