[0001] The utility model relates to the field of fresh-keeping boxes, in particular to a cover body, a box body and a container with the cover body. Background Art
[0002] Fresh-keeping boxes are used to store food such as meat, vegetables, and fruits. Usually, a lid is buckled onto the box body to form a relatively closed space inside the box, which can isolate oxygen outside the fresh-keeping box and prevent oil stains or moisture in the fresh-keeping box from leaking out of the box.
[0003] The existing fresh-keeping box structure includes a box body for storing food and a cover body arranged at the opening of the box body, both sides of the cover body are hinged with cover buckles, and the side walls of the box body are provided with buckles that are engaged with the cover buckles; a circle of U-shaped grooves with an opening downwards is provided on the bottom surface of the cover body corresponding to the edge of the box body opening, and a sealing ring is placed in the U-shaped groove; the cover body is placed on the box body, and the sealing ring is facing the box body opening, and then the cover buckle is rotated downward so that the cover buckle and the buckle are engaged with each other, thereby forming a relatively closed space inside the box body, which is convenient for preserving food; and when the cover body is buckled on the box body, the sealing ring is squeezed and deformed and then pressed against the inner groove wall of the U-shaped groove, thereby enhancing the sealing performance of the fresh-keeping box structure.
[0004] The existing fresh-keeping boxes still have the following shortcomings: first, when the lid is covered on the box body, the user needs to try the operation many times before the sealing ring of the lid is facing the opening of the box body, and then the cover buckle of the lid is smoothly snapped onto the buckle of the box body; secondly, the user needs to exert a lot of force on the lid body to complete the snap connection between the cover buckle of the lid and the buckle of the box body, so as to achieve the sealing effect after the sealing ring is deformed. Utility Model Content
[0005] The first technical problem to be solved by the utility model is to provide a cover body which can realize accurate alignment and buckling with a box body in view of the current status of the above-mentioned prior art.
[0006] The second technical problem to be solved by the utility model is to provide a box body that cooperates with the cover body to achieve accurate alignment and buckling.
[0007] The third technical problem to be solved by the utility model is to provide a container capable of realizing accurate alignment and buckling of a cover body and a box body.

That is, the extending direction of the connecting portion is the same as the extending direction of the second folded edge, and the angle between the connecting portion and the plane where the periphery of the cover is located is equal to the second inclination angle.
[0018] In order to improve the service life of the cover buckle, the cover buckle includes a flange extending from the second folded edge and a fastening buckle arranged on the flange, and the fastening buckle is used to cooperate with the lower end of the first folded edge for clamping;
[0019] A flipping structure for flipping a portion of the second folded edge is disposed on the bottom surface of the second folded edge, and the flange can be flipped simultaneously with the portion of the second folded edge.
[0020] The technical solution adopted by the utility model to solve the second technical problem is: the box body forms a cavity with an upper opening, which cooperates with the cover body.
[0021] The technical solution adopted by the utility model to solve the third technical problem is: the container comprises a box body, the box body forms a cavity with an upper opening, and the above-mentioned cover body is applied.
[0022] Compared with the prior art, the utility model has the advantages that: when the cover is placed on the opening of the box body, the first folded edge has a certain guiding effect on the second folded edge, so that the cover body can slide smoothly to the correct position, thereby eliminating the need for the user to spend more energy to align the cover body with the box body before buckling the cover buckle;
[0023] The sealing ring used in the utility model is in an open shape, which is easier to deform, thereby reducing the force required for buckling the box body and the cover body, making it easier for the user. BRIEF DESCRIPTION OF THE DRAWINGS
