特徴とする箱容器の封緘構造。[Scope of Claim for Utility Model Registration] A sealing structure for closing at least one of the rectangular openings of a box container having a body surrounded by four side walls, the same extension length from each of the four side walls with the opening edge as a fold line. The extension length is determined so that each of the opposing pairs of these four flaps has a tip overlapping dimension necessary for sealing across the middle position of the fold line of these flaps, and One of the flaps is a rectangular first flap, and the other of the pair of flaps is a first flap having a shape in which a rectangular extending portion for overlapping is further provided at the tip of a trapezoidal extending portion extending from the fold line. 2 flaps, each of the other pairs of the four flaps facing each other has a long part located on the inner surface side of the trapezoidal extension part of the second flap when the flap is sealed, and is integral with the long part, A sealing structure for a box container, characterized in that it has a short portion that is positioned from the root of the rectangular extension at the tip of the second flap to the outer surface side of the first flap when the container is sealed.
