を特徴とする合成樹脂製密閉容器。 A container body made of synthetic resin that is open upward and has a generally U-shaped folded edge that opens downward in cross section, and a groove for locking the downward opening is formed in the peripheral edge, and an outer surface of the outer wall of the groove for locking. It consists of a synthetic resin lid body with a flange projecting outward from the flange approximately horizontally, and a thin-walled part surrounding the bottom edge of the flange, and a locking part located below the thin-walled part of the lid body. A circumferential protrusion is provided either on the inner surface of the outer wall of the recessed groove or on the outer surface of the folded edge of the container body that comes into contact with the inner surface of the outer wall of the lid when the lid is closed. 1. A synthetic resin airtight container characterized in that when the lid is in a closed state, the lid and the container body can be melted and linearly fused together by applying ultrasonic energy.
