    摘要: A closure assembly for a container comprises a closure cap (1, 101, 201) having an open ended body (2, 102, 202) with a peripheral wall (3, 103, 203) and a top wall (4, 104, 204) provided with a dispensing passage (5, 105, 205) which is defined by a collar (6, 106, 206) arranged to the top wall (4, 104, 204). A self closing valve (20) is arranged in the closure cap (1, 101, 201). The valve (20) comprises a slitted central portion (21 ) and a skirt (23) extending downwardly from the central portion (21), which has an outwardly extending flange (24). The skirt (23) is arranged in the collar (6, 106, 206) and the flange (24) is located below the collar (6, 106, 206) and extends radially outwardly beyond it. On a lower surface of the top wall (4, 104, 204), a plurality of lips (8, 108, 208) are formed outward from the collar (6, 106, 206). The lips (8, 108, 208) are folded over the flange (24) such that the latter is partly enveloped between the lips (8, 108, 208) and the top wall (4, 104, 204) so as to secure the valve (20) in the closure cap (1, 101, 201).
