  • Dispensing closures
    Patent number: 6371340
    Abstract: 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).
