<p>The container (2) has a valve (11) actuated by a sideways pressure on its stem (12) produced by tilting its outlet nozzle (20) after removing a locking cap (30) which has stays (33) to prevent the nozzle being moved. The nozzle, attached to the container by a separate mounting ring (13), has a threaded surface (31) at its broader end engaging with a matching thread (32) on the cap. The nozzle thread is separated from its outlet (22) by a zone with its diameter increasing from the outlet to the thread.</p> |
