| 摘要 |
The invention relates to a child-resistant nozzle for a hand operated sprayer. The nozzle (12) is rotatable relative to a nose bushing (17) at the discharge end of the sprayer into positions of relative adjustment including a liquid flow OFF position and one or more liquid flowing positions. The nozzle (12) and nose bushing (17) have cooperating surfaces in which passages are formed, which passages when brought into register by relative adjustment of the nozzle and discharge end determine the mode of liquid discharge, i.e. SPRAY or STREAM. A locking member (62) is provided on the nose bushing (17) which cooperates, when engaged, with a recess (58) in the rotatable nozzle (12) to prevent sprayer operation by preventing rotation of the nozzle on the nose bushing from said liquid flow OFF position without simultaneously deflecting an arm (60) to disengage the locking member (62), and rotating the nozzle. |
