A lid (12) threadably engages with an open head container (10) with a seal (106) located between tapered surfaces of the lid and container such that compression of the seal occurs gradually as the lid (12) is threaded onto the container (10). The lid (12) is equipped with a torquing tool (42) which pivots at a point (70) along a ridge (30) at the edge of the lid (12). In a stored configuration, the torquing tool (42) has a handle (46) which is at least partially contained within a chamber (34) in the lid and a base (44) of the torquing tool has a top surface which is coplanar with the top surface of the lid. The torquing tool has an abutment (68). To utilize the torquing tool (42), the handle is rotated about the pivot (70), to an extended position. The handle may then assist in threading and unthreading the lid.
