A dispensing closure for a liquid product such as a liquid soap has a self-closing valve (12, 112) having a mounting ring (20, 120) and a dispensing head (24, 124) attached to the mounting ring by a generally cylindrical connecting wall (22, 122). The valve is located in the dispensing aperture (68, 168) of a closure body (10, 110, 110') so as to form a seal against product escape. Retention of the mounting ring in its sealing position is provided by a resilient clamping ring (80, 180) of the closure body, which is turned inwardly against the mounting ring by means of a three-part mandrel (90).

1. A method of securing a self-closing valve (12,112) having a mounting ring (20,120) in the assembly of a dispensing closure, the method being characterised by the following steps:a) providing a closure body (10,110) with a downwardly directed abutment face (72,172) surrounding a dispensing aperture (68,168) in which the valve is to be located, and a generally cylindrical, skirt (74,174) dimensioned to accept the mounting ring and extending downwardly of the closure to a free edge (82,182) axially spaced from the abutment face, a portion (80,180) of the skirt including the free edge (82,182) being inwardly deformable; b) providing the mount ng ring (20,120) of the self-closing valve (12,112) with an upwardly directed abutment face (30,130) engageable with the/abutment face (72,172) of the closure body (10,110); c) entering the valve (12,112) into the skirt (74,174) of the closure body (10,110) with the abutment faces (30,72 and 130,172) in opposition; and d) inturning deformable portion (80,180) of the skirt (74,174) against the mounting ring (20,120) so that it holds the mounting ring with the abutment faces (30,72 and 130,172) in mutual abutment and with the closure body (10,110) and the valve (12,112) in sealing relation.
