An aseptic closure for containers of liquids comprising a main body provided with a threaded ring, which is designed to be associated with a neck of a container and from which there protrudes a tubular projection which is coupled to an upper closure. A step protrudes from the inside wall of the projection, proximate to the main body, and forms a passage hole which is controlled by a flow control element which is monolithic, by means of radial supporting bridges, with respect to the upper closure; the upper closure has a tubular structure and can slide axially along the projection from a lowered position, which closes the hole because the flow control element forms a seal against its wall, to a raised position for opening the hole for the passage of the liquid.

[ What is claimed is:] [1.]1. An aseptic closure for containers of liquids, comprising a main body provided with a threaded ring, which is arranged to be associated with a neck of a container and from which a tubular projection protrudes which is coupled to an upper closure, wherein a step protrudes from an inside wall of said projection, proximate to the main body, and forms a passage hole which is controlled by a flow control element which is monolithic, by means of radial supporting bridges, with respect to said upper closure, said upper closure having a tubular structure and being able to slide axially along said projection from a lowered position, which closes said hole because said flow control element forms a seal against its wall, to a raised position for opening said hole for the passage of the liquid.
