description The utility model relates to a seamless conjoined paper lunch box. A box cover and a box body are connected into a whole through a connection edge. The upper parts of the box cover and the box body are respectively provided with a folding edge and the bottoms of the box cover and the box body are rectangular planes. Four edges of each of the planes are inclined upward and a cross section is a trapezoid. Spatial angle points are provided with inward concave circular arc grooves and reinforcing ribs in the shape of convex columns are formed among the grooves. Thus the rigidity is improved and the aesthetic performance is increased. When the box cover and the box body are buckled, the folding edges are fastened exactly. The lunch box has no wrinkles, has the advantages of high temperature resistance and water resistance and is suitable for Chinese hot drink food.
