Description

Technical Field

[0001] The present application relates to the field of food packaging boxes, and in particular to a double-layer paper box. Background Art

[0002] The main materials of existing disposable lunch boxes are petrochemicals (plastics), straw (starch, paper plastic) and paper. In recent years, it has been revealed that petrochemical lunch boxes are mostly made of recycled plastics, which are less safe and cause great harm to the human body during use. During the production process of straw lunch boxes, a certain proportion of petrochemical materials such as plastics are added, which can also cause harm to the human body. Paper lunch boxes are easy to biodegrade and highly safe. They are environmentally friendly and harmless disposable lunch boxes. As people pay more and more attention to catering safety, paper lunch boxes have a broader application prospect.

[0003] In the process of using paper lunch boxes, people found that the structure of paper lunch boxes is simple and it is not convenient to pack different types of meals. During use, one type of meal requires a separate paper lunch box to pack, which makes the packaging cost high and multiple lunch boxes are not convenient for transportation.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the existing paper lunch boxes have the problems of high packaging cost and inconvenience in transportation. Utility Model Content

[0005] In order to solve the problem that existing paper lunch boxes have high packaging costs and are inconvenient to transport, the present application provides a double-layer paper lunch box.

[0006] The present application provides a double-layer paper lunch box, which adopts the following technical solution:

[0007] A double-layer paper lunch box comprises a paper lunch bucket main body and an upper bucket bottom structure, wherein the paper lunch bucket main body is a truncated cone structure, the bottom diameter of the paper lunch bucket main body is smaller than the diameter of the top opening of the paper lunch bucket main body, and an easy-tear cover is provided at the top opening of the paper lunch bucket main body; an annular indentation is provided on the side wall of the paper lunch bucket main body, and the annular indentation divides the paper lunch bucket main body into an upper bucket part and a lower bucket part, the lower bucket part is a top opening structure, both ends of the upper bucket part are opening structures, one end of the upper bucket part away from the lower bucket part is connected to the easy-tear cover, and the upper bucket bottom structure is inserted into the upper bucket part and clamped with the side wall of the upper bucket part.

[0008] By adopting the above technical solution, when packing meals, first add staple food to the lower barrel part, then insert the upper barrel bottom structure into the upper barrel part, and add dishes to the upper barrel bottom structure and the upper barrel part. The upper barrel part is a truncated cone structure, and the upper barrel bottom structure is clamped with the side wall of the upper barrel part, so that the connection stability between the upper barrel part and the upper barrel bottom structure is good. Finally, the easy-tear cover is fixed to the top of the side wall of the upper barrel part, so as to achieve sealed packaging of food. The staple food and dishes can be packaged in one lunch box, which saves the packaging cost of paper lunch boxes and reduces transportation costs. Customers separate the upper barrel part from the lower barrel part through the annular indentation, and then open the easy-tear cover to eat the food. The opening method is simple and convenient, and the separation effect of dishes and staple food is good, which is conducive to improving the customer's consumption experience.

[0009] Optionally, the upper barrel bottom structure includes a bottom plate and an annular side plate, the annular side plate is connected to the bottom plate, and when the upper barrel bottom structure is inserted into the upper barrel part, the annular side plate abuts against the side wall of the upper barrel part.

[0010] By adopting the above technical solution, the annular side panel abuts against the side wall of the upper barrel part, and the upper barrel part is a conical structure, so that the bottom structure of the upper barrel is stably connected to the upper barrel part after being inserted into the upper barrel part. After adding dishes to the upper barrel part, the weight of the dishes makes the connection between the annular side panel and the upper barrel part more stable, which is beneficial to improving the packaging effect of the upper barrel part on food, reducing the phenomenon of mixing of different types of food during transportation, thereby improving the customer's consumption experience.

[0011] Optionally, the height of the annular side panel is 3 cm.

[0012] By adopting the above technical solution, the height of the annular side plate is 3 cm, which is conducive to improving the packaging effect of dishes and reducing the leakage of soup.

[0013] Optionally, a partition plate is provided on the bottom plate, the partition plate is connected to the annular side plate, and the height of the partition plate is higher than the height of the annular side plate and lower than the height of the side wall of the upper barrel part.

[0014] By adopting the above technical solution, the setting of the partition plate is conducive to simultaneously holding multiple dishes in the upper barrel part and separating different types of dishes, thereby improving the packaging effect of the upper barrel part and preventing different types of dishes from mixing.

[0015] Optionally, a portion of the partition plate that is higher than the annular side plate abuts against a side wall of the upper barrel portion.

[0016] By adopting the above technical solution, the separation performance of the partition plate for different dishes is further improved, and the phenomenon of mixing between different dishes is further reduced.

[0017] Optionally, the partition includes a two-zone partition, a three-zone partition and a four-zone partition, the two-zone partition divides the upper barrel part into two food zones, the three-zone partition divides the upper barrel part into three food zones, and the four-zone partition divides the upper barrel part into four food zones.

[0018] By adopting the above technical solution, multiple types of partition plates are provided, which is convenient for users to pack different quantities of dishes according to usage needs, thereby increasing the application scope of the double-layer paper lunch box.

[0019] Optionally, the partition plate includes a first vertical plate and a second vertical plate arranged in parallel, one end of the first vertical plate is connected to the bottom plate, and the other end is connected to a connecting plate, one end of the second vertical plate is connected to the bottom plate, and the other end is connected to the connecting plate, and a gap is arranged between the first vertical plate and the second vertical plate.

[0020] By adopting the above technical solution, the partition plate is composed of a first vertical plate, a second vertical plate and a connecting plate, and this structure increases the supporting effect of the partition plate, thereby improving the partition stability of the partition plate. The improvement of the supporting effect of the partition plate is conducive to improving the structural stability of the upper barrel part, reducing the deformation of the upper barrel part after the dishes are placed, and is conducive to the use of a lighter and thinner side wall structure in the production process of the upper barrel part, thereby saving paper resources and further reducing the production cost of the upper barrel part.

[0021] Optionally, a reinforcement plate is provided between the first vertical plate and the second vertical plate, and the reinforcement plate is connected to the first vertical plate and the second vertical plate respectively.

[0022] By adopting the above technical solution, the provision of the reinforcement plate further improves the structural stability of the partition plate, thereby further improving the partition stability and the structural stability of the upper barrel part.
