<p>An improved closure (11) for containers, in particular drinks, comprising a main body (12), with a threaded locking ring, to be associated with a neck of a container, from which a tubular projection (14) extends, coupled with a cap element (21), said main body (12) having a central hole (15) concentric to said projection (14) and intercepted by an island flow control element (27) fixedly connected through radial bridges (26) with respect to said cap element (21), said cap element (21) having a tubular structure and being able to slide axially along said projection (14) from a lowered position, closing said hole (15) through said island flow control element (27), to a raised position opening up said hole (15) for the passage of the liquid, characterised in that said hole (15) is surrounded by an annular ridge (20) that extends coaxially inside said projection (14) towards said island flow control element (27) making a labyrinth seal when associated with the island flow control element (27) itself.</p> |
