Claims (1)

[Scope of Claim for Utility Model Registration] (1) Consisting of a box-shaped container body with an open top and a lid that closes the top opening of the container body, the joint between the container body and the lid when the lid is closed. A convex strip having a width smaller than the joint width is provided approximately at the center in the width direction on one side, and a concave strip having a width smaller than the joint width is provided on the other side, and a concave strip is provided inside the convex strip and is open to the joint surface side. An airtight container made of foamed synthetic resin, in which the vertical walls on both sides of the grooved grooves have a bottom surface located closer to the joint surface than the bottom surface of the grooves, and a recess for air release that is open to the joint surface side. (2) The upper end surface of the side wall of the container body is the joint with the lid, and the width is expanded at the tip approximately in the widthwise center of the joint on the lower surface of the lid within a range smaller than the width of the upper end surface of the side wall of the container body. A convex strip having a protrusion is provided below, and a concave strip that opens upward in a shape that matches the convex strip of the lid is provided on the upper end surface of the side wall of the container body, and a concave strip provided on the upper end surface of the side wall of the container body is provided on both sides. 2. The airtight container according to claim 1, wherein the vertical wall of the container is provided with a recess for releasing air that is open upward and whose bottom surface is positioned above the bottom surface of the concave groove, and which is positioned facing each other. (3) Consists of a box-shaped container body with an open top and a lid that closes the top opening of the container body, and when the lid is closed, one side of the joint between the container body and the lid is biased to one side. A convex strip with a width smaller than the joint width is provided on the other side, and a concave strip is provided on the other side with the convex strip inside and open to the joint surface side and the sides. An airtight container made of foamed synthetic resin, in which the vertical wall of the row side has a bottom surface located closer to the joining surface than the grooved bottom surface, and a recess for air release that is open to the joining surface side. (4) Consisting of a box-like container body with an open top and a lid that closes the top opening of the container body, at least the inner periphery of the bottom surface of the lid where it joins the container body when the lid is closed. An inner protrusion is provided throughout the container body to be inserted tightly into the upper part of the opening between the side walls of the container body, and in the width direction of the upper end surface of the side wall of the container body, there is provided an inner protrusion of the lid body when the lid body is closed. An airtight container made of foamed synthetic resin that is shallower than the interior depth and has an upwardly open recess for air release.
