Patent ID: 7399361

Claim:
An apparatus for applying fluid from a fluid source to a substrate, comprising: a housing configured to receive the fluid from the fluid source, said housing including a nozzle contact surface, a fluid outlet in said nozzle contact surface, a projection extending downwardly from said nozzle contact surface, a guide surface on said projection and inclined relative to said nozzle contact surface to define an undercut surface on said projection, and first alignment structure on said projection between said guide surface and said nozzle contact surface, said first alignment structure extending away from said undercut surface and adapted to vertically support a nozzle on said housing; a nozzle arrangement in fluid communication with said housing, said nozzle arrangement having an inlet side positioned adjacent said nozzle contact surface, an outlet side opposite said inlet side, a discharge passage communicating with said fluid outlet and extending from said inlet side to said outlet side, opposed first and second sidewalls between said inlet side and said outlet side, a surface proximate said outlet side and engaging said guide surface of said housing, and second alignment structure on said second sidewall, said second alignment structure cooperating with said first alignment structure on said projection to align said fluid outlet with said discharge passage; and a lever pivotally mounted to said housing for releasably securing said nozzle arrangement adjacent said nozzle contact surface, said lever having a lower end cooperating with said first sidewall such that said nozzle arrangement may be linearly guided in a direction transverse to the direction of fluid flow from the outlet between said lower end of said lever and said projection of said housing.
