DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a leak-proof structure of an environmentally friendly lunch box. Figure 1-Figure 3, including a lunch box 1, the top cover of the lunch box 1 is provided with a lunch box cover 2, the inner wall of the lunch box cover 2 is connected with a sealing block 13, and a sealing ring 15 is sealed between the sealing block 13 and the inner wall of the lunch box cover 2 to ensure the sealing of the connection with the lunch box 1, and an exhaust hole 14 is opened inside the sealing block 13. An exhaust valve 3 is installed at the center of the top of the lunch box cover 2. The exhaust valve 3 can be opened to discharge the internal gas through the exhaust hole 14 to ensure the air circulation in the lunch box 1 and prevent the food from spoiling in a closed environment. The outer wall of the bottom end of the lunch box cover 2 is an integrated structure and is fixed with a cover edge 16 adapted to the leak-proof sleeve 6. The lunch box 1 is matched with the lunch box cover 2, and the lunch box cover 2 is closed on the lunch box 1 to effectively prevent food leakage.

[0020] like Figure 2 As shown, the interior of the lunch box 1 is provided with a degradable paper liner 11, which is made of paper or biodegradable materials, has good environmental protection performance, and is in line with the current trend of green development. The side wall of the lunch box 1 is provided with an anti-slip groove 4 to improve the anti-slip property. The interior of the lunch box 1 is provided with a cavity 9 adapted to the degradable paper liner 11, and the inner wall of the bottom end of the cavity 9 is equidistantly distributed with a plurality of arc-shaped protrusions 10 for support, which can support the bottom of the degradable paper liner 11, and the degradable paper liner 11 is easy to replace, so that the lunch box 1 can be recycled, saving energy.

[0021] Specifically, the outer wall at the top of the lunch box 1 is an integral structure and is provided with a leak-proof card sleeve 6, a sealing groove 8 is opened inside the leak-proof card sleeve 6, and a supporting edge 12 adapted to the sealing groove 8 is provided on the top of the degradable paper liner 11, which is convenient for accommodating the supporting edge 12 and the box cover edge 16, and can effectively prevent food leakage and improve the sealing of the contact surface. A limiting edge 7 is provided on the top of the inner wall of the leak-proof card sleeve 6, and the limiting edge 7 is made of soft material and has certain elasticity and durability. When the lunch box cover 2 is closed on the lunch box 1, the limiting edge 7 can be tightly fitted on the outside of the lunch box cover 2 to form an effective leak-proof barrier;

[0022] In addition, overflow pipes 5 are installed at the corners of the outer wall of the lunch box 1, and the top of the overflow pipe 5 extends to the inside of the leak-proof sleeve 6. The overflow pipe 5 is made of an airbag tube material, surrounds the bottom edge of the lunch box 1, forms an annular structure, and is communicated with the leak-proof sleeve 6 to collect water vapor or overflowed oil stains, forming a double leak-proof barrier, which can effectively prevent food leakage and improve the practicality of the lunch box 1.

[0023] The implementation principle of the leak-proof structure of an environmentally friendly lunch box in the embodiment of the present application is as follows: when in use, the degradable paper liner 11 can be unfolded and placed in the cavity 9 in advance, and the supporting edge 12 can be fitted with the inner side of the sealing groove 8 to limit the position, and then the food can be placed in the degradable paper liner 11, and the arc-shaped protrusion 10 can support its bottom, and then the lunch box cover 2 is installed. Since the limiting edge 7 is made of soft material and has a certain elasticity, it is convenient to extend the lid edge 16 to the sealing groove 8 and fit closely with the inner wall of the leak-proof sleeve 6. When the lunch box cover 2 is covered on the lunch box 1, the limiting edge 7 can be closely fitted to the outside of the lunch box cover 2 to form an effective leak-proof barrier. At this time, the sealing block 13 also seals the upper part of the degradable paper liner 11 to prevent food from swaying and splashing inside the lunch box 1 during movement. The gas can also be discharged through the exhaust hole 14 by opening the exhaust valve 3 to ensure air circulation in the lunch box 1 and prevent food from deteriorating in a closed environment.
