Abstract: A screw top closure comprising a screw lid (10) with internal threading and a separate lid attachment (11) with external threading. The lid attachment (11) is designed for application on the neck (12) of a container (13) to carry the removable lid, the lid attachment (11) being in the form of an annular element with an upper part (14) serving as support for the lid (10), and two concentric tubular flanges (15, 16) protruding downwardly therefrom. These flanges between them in downward direction define an open pocket (17) for receipt of the neck (12) of the container (13).
