The technical scheme of the utility model is:

An all-paper lunch box, comprising a piece of oil-proof and waterproof cardboard for making the lunch box, the cardboard includes a cover 1 and a bottom 2, the cover 1 includes three side walls 11, The bottom 2 includes four side walls 21, 22, and 23. It is characterized in that the two ends of the side wall 22 are provided with corners 221, and the rear end of the side wall 21 is provided with a gap above, and is attached to the side wall when folded. The knuckle 211 on the outer surface of the knuckle 221, the two ends of the side wall 23 are provided with a knuckle 231, and the front end of the side wall 21 is also provided with a knuckle 212 on the outer surface of the knuckle 231 when folded.

The inner surface of the lunch box is coated with a kind of oil-proof, water-proof and non-toxic chemical preparation which only takes effect in a short period of time after the lunch box is used.

The all-paper lunch box described in the utility model is made by folding and bonding a piece of cardboard cut into a certain shape, and the manufacturing process is all mechanized. The inner surface of the lunch box is chemically treated to be waterproof and oil-proof. The chemicals used are non-toxic and have been approved by the US Food and Drug Administration.

The all-paper lunch box described in the utility model is simple to make and easy to use. The production machinery is fully automated and can be mass-produced without manual work. It is waterproof and oil-proof. About one day after use, the chemicals coated on the inner surface are waterproof. The anti-oil performance is reduced, so it can be decomposed naturally after being discarded, and does not pollute the environment. Paper products can also be recycled. The notch design at the four corners of the lunch box reduces the overlapping thickness, makes the bonding more compact and easy, and saves adhesive. The four side walls of the bottom of the box are designed to be inclined, which can be stacked for storage, saving space, saving packaging and transportation costs.

The lunch box of the utility model will be described in detail below in conjunction with the accompanying drawings. in:

Fig. 1 is in order to make the cardboard schematic diagram of the cutting of this lunch box;

Fig. 2 is a schematic diagram of the cardboard folding process shown in Fig. 1 .

The all-paper lunch box of the utility model is made of a cut and formed oil-proof and fire-proof cardboard, the cardboard includes a cover 1 and a bottom 2, and the cover 1 includes three side walls 11, The bottom 2 includes four side walls 21 and 22, 23, the two ends of the side wall 22 are provided with knuckles 221, and the rear end of the side wall 21 is provided with a gap on the top, which is attached to the outer surface of the knuckles 221 when folded. Knuckle 211. Similarly, both ends of the side wall 23 are provided with knuckles 231 , and the front end of the side wall 21 is also provided with a knuckle 212 with a gap above, which is attached to the outer surface of the knuckle 231 when folded.
