[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figs. 1-3 As shown, the technical solution adopted by this utility model is as follows: A biodegradable plastic lunch box with an internal interlayer includes a box body 1, a box lid 2, and multiple inner boxes 3 placed inside the box body 1; the box body 1 includes a corrugated portion 11 and a bottom box portion 12, and the box body 1 is sealed to the box lid 2 through the corrugated portion 11. Limiting structures are provided on the multiple inner boxes 3 and the bottom box portion 12. When the lunch box is in use, the corrugated portion 11 of the box body 1 extends to form a cavity for accommodating the multiple inner boxes 3, and the multiple inner boxes 3 are arranged in a longitudinally supported state through the limiting structures; when the lunch box is not in use, the corrugated portion 11 of the box body 1 contracts, and the multiple inner boxes 3 are arranged in a longitudinally stored state through the limiting structures. The multiple inner boxes 3 solve the problem of food distribution. Due to the extensibility of the corrugated portion 11, the number of inner boxes 3 can be flexibly adjusted during use. When not in use, the multiple inner boxes 3 are stacked longitudinally through the limiting structures, reducing space occupancy and improving the lunch box's storage capacity.

[0020] In this embodiment, the limiting structure includes a first limiting part 4 and a second limiting part 5, which are respectively disposed on opposite sides of the bottom box part 12 and the inner box 3. Preferably, in order to improve the production efficiency and overall strength of the lunch box, the first limiting part 4 and the second limiting part 5 are integrally formed on the bottom box part 12 or the inner box 3. When the lunch box is in use, the adjacent bottom box parts 12 and the first limiting part 4 and the second limiting part 5 of the inner box 3 cooperate to form a longitudinal bearing state; when the lunch box is not in use, the states of the adjacent inner boxes 3 are swapped, and the adjacent bottom box parts 12 and the first limiting part 4 and the second limiting part 5 of the inner box 3 cooperate to form a longitudinal stacking storage state.

[0021] In this embodiment, when the food container is in use, the first limiting part 4 of any inner box 3 abuts against the adjacent bottom box 12 or the second limiting part 5 of the inner box 3, while the second limiting part 5 of the inner box 3 abuts against the adjacent bottom box 12 or the first limiting part 4 of the inner box 3; this design forms a longitudinally supported state. When the food container is not in use, the first limiting part 4 of any inner box 3 is inserted into the adjacent bottom box 12 or the first limiting part 4 of the inner box 3, while the second limiting part 5 of the inner box 3 abuts against the adjacent bottom box 12 or the second limiting part 5 of the inner box 3; this design forms a longitudinally stacked state.

[0022] In the embodiment, the first limiting part 4 comprises a first ridge part recessed inward to form a supporting surface, and the first ridge part comprises a first matching groove; when the lunch box is in the non-use state, the first ridge part of each inner box 3 is inserted into the first matching groove of the corresponding inner box 3 one by one.

[0023] In the embodiment, the second limiting part 5 comprises a second ridge part recessed inward to form a supporting surface, and the second ridge part comprises two second matching grooves, and a supporting part is formed between the two second matching grooves; when the lunch box is in the use state, the supporting part of each inner box 3 abuts against the supporting surface of the corresponding first ridge part; the first ridge part of the lunch box abuts against the supporting surface of the corresponding second ridge part; and through the cooperation of the first ridge part and the second ridge part, the longitudinal support is formed between the plurality of inner boxes 3 and the bottom box part 12.

[0024] In the embodiment, the inner box 3 comprises a plurality of holding cavities 31 for placing different meals, and the plurality of holding cavities 31 are integrally formed with connecting reinforcing ribs therebetween, so as to improve the overall strength of the inner box 3.
