A plurality of spaced connection bridges 125 are sequentially arranged in the bridge hole 126. A notch 127 connected to the bridge hole 126 is provided at the edge of the extension portion 125 near the position of the fixing portion 122. In this way, the extension portion 125 can be pulled upward by manpower. The flange 123 can lift the extension part 121 when the fixing part 122 is stressed, and can further disconnect the connecting bridge 125 in the bridge hole 126 on either side, so as to tear the lunch box cover 1 through the connecting bridge 125 in the bridge hole 126 on the other side, so as to open the square box cover 2 from the lunch box body 1. After the lunch box cover 1 is opened from the lunch box body 1, since the connecting bridge 125 in the bridge hole 126 on one side has been disconnected, the lunch box cover 1 cannot be fastened to the lunch box body 1 intactly again, so it is easy to judge whether the lunch box cover 1 has been opened from the lunch box body 1 by others during the delivery process of the takeaway.

[0038] The anti-opening lunch box according to the above embodiment of the present invention comprises a lunch box cover and a lunch box body, the lunch box cover comprises a lunch box cover body and a handle buckle arranged on the lunch box cover body, the lunch box cover body horizontally extends on the outer side of the recessed portion to form a lap edge and extends downward along the outer periphery of the lap edge to form a buckling wall arranged in the groove, the buckling wall, the lap edge and the recessed portion together surround a receiving groove for accommodating the second rib, a second buckle cooperating with the first buckle is arranged on the inner wall on the side opposite to the outer side surface of the second rib in the receiving groove, an abutting block for abutting the second rib is arranged on the upper side of the inner wall on the side opposite to the inner side surface of the second rib in the receiving groove, the handle buckle comprises an extension portion extending outward from the outer side wall of the lap edge in the horizontal direction of the lap edge to form the first rib edge and a buckle connected to the extension portion The fixing part is naturally hung down and buckled on the outer wall of the first rib, the lower end of the fixing part is provided with a flange, and a connecting part is respectively provided on both sides of the extension part, the connecting part is arranged in the groove, one side of the connecting part is connected to the buckling wall, and the other side of the connecting part is connected to the fixing part through a plurality of spaced connecting bridges, or the connecting part is arranged above the groove and extends out of the first rib, and the two sides of the fixing part are connected to the connecting part through a plurality of spaced connecting bridges, or one side of the extension part is arranged on the outer wall of the buckling wall, and the other side of the extension part is arranged on the groove and extends out of the first rib, and a bridge hole penetrating the upper and lower surfaces of the extension part is respectively provided on the edges of the two sides of the extension part along the direction from the buckling wall to the first rib, and a plurality of spaced connecting bridges are sequentially arranged in the bridge hole. A connecting bridge is provided, and a notch communicating with the bridge hole is provided at the edge of the extending part adjacent to the fixing part. In this way, after the lunch box cover is buckled on the lunch box body, the buckling wall is provided in a groove, the second rib is accommodated in the accommodating groove, the first ring buckle and the second ring buckle are clamped together, and the abutment block abuts against the second rib, thereby playing a role of sealing and fixing. The flange is pulled upward by manpower. Since the fixing part and the connecting part are connected by a plurality of spaced connecting bridges or since the two sides of the fixing part are connected to the connecting part by a plurality of spaced connecting bridges, or since a plurality of spaced connecting bridges are sequentially provided in the bridge hole, a notch communicating with the bridge hole is provided at the edge of the extending part adjacent to the fixing part. In this way, the flange is pulled upward by manpower. By pulling up the flange, when the fixed part is stressed, the extending part can be lifted, and the connecting bridge in the bridge hole on either side can be further disconnected, so that the lunch box cover can be torn open through the connecting bridge in the bridge hole on the other side, so that the square box cover can be opened from the lunch box body. After the lunch box cover is opened from the lunch box body, since the connecting bridge in the bridge hole on one side has been disconnected, the lunch box cover cannot be fastened to the lunch box body intact again, so it is easy to judge whether the lunch box cover has been opened from the lunch box body manually by others during the delivery of the takeaway, which effectively solves the technical problems that the packaging cover of the packaging box can be opened at any time during the delivery of the takeaway, which may lead to the loss of the contents of the packaging box and the easy introduction of harmful substances such as dust and bacteria.
