TRIGGER SPRAYER NOZZLE ASSEMBLY AND SPRAYER HOUSING ATTACHMENT LOCK

摘要

The present invention pertains to the construction of a manually operated trigger sprayer in which the sprayer housing has a reduced diameter dimension liquid discharge passage to increase the velocity of liquid flow through the liquid discharge passage, and in which the nozzle assembly has a novel configuration that securely attaches the nozzle assembly to the sprayer housing to prevent the increased velocity of liquid flow through the sprayer housing liquid discharge passage from dislodging the nozzle assembly from the sprayer housing. The novel construction of the sprayer housing and the nozzle assembly includes a resilient crossbar provided on the sprayer housing that crosses over the liquid discharge passage and a pair of resilient flanges on the nozzle assembly that engage over opposite sides of the sprayer assembly crossbar and securely attaching the nozzle assembly to the sprayer housing.
