Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0033] Example 1:

[0034] In this embodiment, if Figure 1-2 As shown, the utility model provides a paper double-grid box, comprising a box body 1, wherein the unfolded plane of the box body comprises a first bottom 2, a second bottom 3, a first folding portion 4, a second folding portion 5, a first end portion 6, a first side portion 7, a second end portion 8, and a second side portion 9;

[0035] Both sides of the first bottom are connected to the first side parts, one end of the first bottom away from the second bottom is connected to the first end part, and one end of the first bottom close to the second bottom is connected to the first folded part;

[0036] Both sides of the second bottom are connected to the second side parts, one end of the second bottom away from the first bottom is connected to the second end part, and one end of the second bottom close to the first bottom is connected to the second folding part;

[0037] The two ends of the first folded portion are respectively connected to the first bottom portion and the second folded portion, and the two sides of the first folded portion are respectively connected to the first side portion through the first folded piece 10;

[0038] The two ends of the second folded portion are respectively connected to the second bottom portion and the first folded portion, and the two sides of the second folded portion are respectively connected to the second side portion through the second folded piece 11;

[0039] Both sides of the first end are respectively connected to the first side portion through a third folded piece 12;

[0040] Both sides of the second end are respectively connected to the second side portion through fourth folded pieces 13;

[0041] The first bottom portion, the first folding portion, the first end portion and the first side portion are folded to form a first grid 14;

[0042] The second bottom portion, the second folding portion, the second end portion and the second side portion are folded to form a second grid 15 .

[0043] In this embodiment, it is further configured that the first bottom and the second bottom are both rectangular in shape, the first bottom and the second bottom have the same width, and the length of the second bottom is greater than that of the first bottom.

[0044] In this example, due to functional reasons, the first grid surrounded by the first bottom is a sauce grid, and the first grid surrounded by the second bottom is a food grid. The second grid has a much larger storage space than the first grid, which is convenient for customers to use. Therefore, the length of the second bottom is 4-6 times the length of the first bottom. In another usage, the first grid is a food grid, and the second grid is another food grid, which only separates two kinds of food, or can be used to separate the same kind of food. For this usage, the length ratio of the first bottom and the second bottom can be adjusted.

[0045] In the present embodiment, it is further arranged that the widths of the first end portion, the first side portion, the second end portion and the second side portion are the same, so as to facilitate the connection of the first side portion and the second side portion after folding.

[0046] In this embodiment, it is further configured that the first folding piece is the same size as the second folding piece, and the third folding piece is the same size as the fourth folding piece.

[0047] In this embodiment, it is further configured that the first folding portion and the second folding portion are symmetrical, and the widths of the first folding portion and the second folding portion are smaller than the widths of the first end portion, the first side portion, the second end portion, and the second side portion.

[0048] In this embodiment, it is further configured that the contours of the first bottom, the second bottom, the first folded portion, the second folded portion, the first end, the first side, the second end, and the second side are all pre-pressed molding lines 16. The provision of the pre-pressed molding lines facilitates the folding of the connection between the first bottom, the second bottom, the first folded portion, the second folded portion, the first end, the first side, the second end, and the second side, so that the formed box body has the same specification shape.

[0049] In this embodiment, the first folding piece, the second folding piece, the third folding piece and the fourth folding piece are further provided with intermittent tangent lines 17 in the middle. The provision of the intermittent tangent lines facilitates the folding of the first folding piece, the second folding piece, the third folding piece and the fourth folding piece, and the folding degree is higher, which further facilitates the folding and forming of the first and second compartments of the box body.

[0050] In this embodiment, a rounded edge 18 is provided at one end of the second side portion close to the first side portion. The rounded edge can have a larger contact area with the first side portion, which is convenient for connection with the first side portion.

[0051] Example 2:

[0052] In this embodiment, if Figure 3 As shown, the unfolded flat surface of the box body is heat-sealed and covered with a laminated paper 19, and white cardboard or kraft paper is underneath the laminated paper. Both the laminated paper and the white cardboard or kraft paper are degradable, and the laminated paper is also waterproof and oil-proof. The box body has a low cost and high environmental performance.

[0053] Example 3:

[0054] In this embodiment, if Figure 1-2 As shown, compared with the traditional long boat box, the box body of this box has a double-grid area. For some specific foods, especially French fries, chicken nuggets, etc., one grid can hold food while the other grid holds the corresponding sauce, so that one box can be used for two purposes, avoiding the inconvenience of having both food and sauce in one box.

[0055] Compared with lunch boxes or pastry boxes, this box has no lid and its usage is clearly for dine-in, so there is no need to add a lid, which is lower in cost and more environmentally friendly due to its material.

[0056] The folding process of the paper double-grid box is as follows: the pre-processed cardboard is stacked in the storage unit, and a single piece of cardboard is pushed to the positioning unit by the pushing unit, pressed by the pressing unit above, and then transported to the top of the collection unit by the conveying unit. A secondary pressing unit is provided above the collection unit, and the secondary pressing unit performs secondary pressing on the cardboard clamped by the conveying unit and pushes it downward to the collection unit.

[0057] The structural principle of the paper double-grid box is that the first bottom, the first folding part, the first end and the first side are folded along the pre-pressed forming line to form a first grid, and the second bottom, the second folding part, the second end and the second side are folded along the pre-pressed forming line to form a second grid. At the same time, the first folding piece, the second folding piece, the third folding piece and the fourth folding piece are folded along the intermittent tangent line to form a box body with a first grid and a second grid connected by the first folding part and the second folding part. The first grid and the second grid can hold sauces and food respectively, or two kinds of food or the same kind of food. The first folding part and the second folding part play a separating role. The unfolded flat surface of the box body is heat-sealed and covered with laminated paper. The laminated paper is also waterproof and oil-proof, and is more environmentally friendly.
