A hazardous materials containment bottle provides greater sealing against the environment by the combination of a funnel-like cone-shaped insert with a lid which includes a downward projecting stopper that mates with an aperture in the center of the insert. A second sealing point is provided by a circular rim at the top of the insert which is compressed between a ledge along the top of the bottle sidewall and the underside of the lid. A third sealing point is provided by a gasket between the outer circumference of the lid and a flange around the mouth of the bottle.
