A waste container includes a generally cylindrical double-wall drum having separate spaced-apart inner and outer sidewalls and separate spaced-apart inner and outer bottom walls. The inner and outer sidewalls are continuously connected along their upper ends and the inner and outer bottom walls are connected at a plurality of spaced-apart locations. A double-wall lid is provided to seal the container. A neck portion is formed at the upper end of the drum and includes a series of buttress threads on the interior face thereof adapted to engage buttress threads on the lid. A vertically-oriented annular trough is formed below and inwardly of the threads in the neck portion and is adapted to engage an annular toe depending from the lid. An upwardly projecting annular lid is formed immediately adjacent to and inwardly of the annular trough in the drum portion, so as to form an annular S-shaped surface with the annular trough. A cooperating upwardly depressed annular trough in the lid forms an S-shaped surface adapted to engage the S-shaped surface in the drum to form a tight fluid seal.
