Abstract
Abstract A right-angle spray-nozzle for a squeeze bottle is in the form of a one-piece body and utilizes only one velocity-increasing orifice, thereby avoiding the undesirably slow venting associated with a squeeze bottle having a high velocity jet of liquid that intersects with a second high velocity jet of air.

A spray-dispensing nozzle comprising a one-piece body having a side and a bottom and internally formed with a transverse first passage having a front end opening through said side; a longitudinal second passage having a bottom end opening from said bottom and a top end opening into the first passage without velocity-increasing restrictions so as to cause a solid column of liquid to rise with an exposed top surface in said first passage when the second passage's said bottom end is supplied with a flow of solid liquid, said first passage overlapping said top end of the second passage and having a back end adjacently behind the second passage's said top end, said body having a longitudinal third passage having a bottom end opening from said bottom and adapted to be supplied with a flow of air, said third passage opening into the first passage's said back end via a bend and a velocity-increasing orifice pointing axially forward into said first passage toward the latter's said front end and at a level spaced above the second passage's said top end and adapted to eject a high-velocity air jet which shears off liquid from said top surface of said solid column of liquid, when the bottom end of said third passage is supplied with said flow of air; said body having a longitudinal fourth passage having a bottom end opening from the body's said bottom and a top end opening into said first passage between its said front end and the top end of said second passage, said fourth passage being of small cross-section as compared to that of the other of said passages; and in which the front end of said first passage forms a counterbore of enlarged cross-section relative to that of the first passage and the fourth passage's said top end opens transversely into this counterbore and a fittment having a nozzle orifice is inserted in said recess, said counterbore forming an annular shoulder and said fittment having an inner end formed by vanes which curve around the fittment's said nozzle orifice and having interspaced circumferential ends, said vanes having inner sides substantially contacting said shoulder.
