An upper pressing groove 15 is provided at the top of the aluminum foil box lid 1. The upward pull edge design ensures that soup does not leak during transportation, and the design prevents hand injuries when opening, significantly improving user satisfaction.

[0036] Figures 1 to 8 The high-temperature resistant and environmentally friendly aluminum foil lunch box shown includes an aluminum foil box top cover 1 and an aluminum foil box bottom 16. The top of the aluminum foil box top cover 1 has a brand area 2 and a name area 3. One side of the aluminum foil box top cover 1 has a sealing folded corner 6, one side of the aluminum foil box top cover 1 has a leak-proof pressing groove 10, one side of the aluminum foil box top cover 1 has a leak-proof pressing corner 11, and the aluminum foil box top cover 1 has a leak-proof pressing straight edge 12. The top of the aluminum foil box bottom 16 has a tight pressing edge 20 and a leak-proof rounded edge 21. The edges of the aluminum foil box top cover 1 and the aluminum foil box bottom 16 adopt a double-layer aluminum foil physical flattening process, replacing the traditional adhesive tin foil cover design. The upper edge of the aluminum foil box bottom 16 is outwardly folded and the inner edge of the aluminum foil box top cover 1 is formed by cold pressing mold in one step, forming a tightly interlocking physical sealing layer. The sealing folded corner 6, the anti-leakage pressing groove 10, the anti-leakage pressing rounded corner 11, and the anti-leakage pressing straight edge 12 on one side of the aluminum foil box top cover 1, the tight pressing edge 20 at the upper end of the aluminum foil box bottom 16, and the anti-leakage rounded edge 21 of the aluminum foil box bottom 16 work together to achieve a seal by relying on the plastic deformation of the aluminum foil material itself. No adhesive is required. The physical pressing technology can maintain structural stability after high temperature testing and no harmful substances are released.

[0037] Figures 1 to 8 The aluminum foil box lid 1 shown has a long anti-slip folded edge 8 on one side and a short anti-slip folded edge 9 on the other side. The side wall of the aluminum foil box lid 1 has an anti-slip texture, allowing for precise engagement with the grippers of the cooking machine's robotic arm, achieving stable forking and rotation at any angle. The bottom of the aluminum foil box bottom 16 has several anti-slip grooves 17, forming a pleated structure. The bottom of the aluminum foil box bottom 16 adopts a regular prismatic pleated design, forming a three-dimensional heat-conducting grid. This structure increases the bottom heating area, promotes hot air circulation, ensures even temperature distribution during frying, and avoids localized overheating.

[0038] Figures 1 to 8The aluminum foil box bottom 16 shown has anti-slip folded edges 18 on both sides of the front and anti-slip folded edges 19 on both sides of the side. The side walls of the aluminum foil box bottom 16 have anti-slip textures, allowing for precise engagement with the grippers of the cooking machine's robotic arm, achieving stable forking and rotation at any angle. The aluminum foil box top cover 1 and the aluminum foil box bottom 16 are made of food-grade aluminum foil substrate. The food-grade high-temperature resistant aluminum foil box has undergone repeated testing and possesses a high-temperature resistance of 500℃ while maintaining material ductility.

[0039] Figures 1 to 8 The workflow when the aluminum foil box is used in a cooking machine is as follows: Ingredients are placed inside the box, which is then placed in a food storage container for preservation. The cooking machine's robotic arm uses a slot to pick up the aluminum foil box and delivers it to the cooking chamber. After the cooking machine starts, the aluminum foil box rotates 360° and flips according to the cooking mode (it can also be used for steaming). The aluminum foil box's structure promotes even heating of the ingredients. During cooking, the ventilation holes around the box automatically regulate the internal air pressure to prevent bloating or leakage. After cooking, the robotic arm removes the aluminum foil box and places it on a conveyor belt for serving. The user can then tear the foil box along the pre-compression lines on the pull edge for use.

[0040] Working principle: The edges of the aluminum foil box top cover 1 and the aluminum foil box bottom 16 adopt a double-layer aluminum foil physical pressing technology, replacing the traditional adhesive tin foil cover design. The outer edge of the aluminum foil box bottom 16 and the inner edge of the aluminum foil box top cover 1 are formed by cold pressing mold in one step to form a tightly interlocking physical sealing layer. The sealing folded corner 6, the anti-leakage pressing groove 10, the anti-leakage pressing rounded corner 11, and the anti-leakage pressing straight edge 12 on one side of the aluminum foil box top cover 1, the tight pressing edge 20 at the top of the aluminum foil box bottom 16, and the anti-leakage rounded edge 21 of the aluminum foil box bottom 16 work together to achieve a seal by relying on the plastic deformation of the aluminum foil material itself. No adhesive is required. It can still maintain structural stability after high temperature test and no harmful substances are released.
