Abstract

Abstract A dispensing spray nozzle particularly adapted for application to a squeeze bottle containing a liquid product, comprises two interfitting parts integrally formed as a single plastic injection molding and including an integral hinge on which, after being injection molded with the hinge holding the two parts side-by-side, the parts can be swung together into interfitting relation so as to produce a finished assembly ready for use.

Claim 1
Independent Claim 241 words
A dispensing nozzle comprising at least two parts which fit together so as to form an assembly, a first part having an entrance for a fluid product to be dispensed and a second part having a dispensing spray orifice connecting with said entrance; wherein the improvement comprises said two parts being formed by a single integrated plastic molding with the parts interconnected by a hinge on which the parts swing so as to fit together, said first part comprising a plug adapted to fit a bottle mouth and forming a cavity having a bottom from which a post extends upwardly with two holes opening through said bottom on opposite sides of said post, and said second part comprising a tab extending from the periphery of the first part to an internally solid insert fitting in said cavity and having a recess fitting over opposite sides of said post and spanning said two holes when said parts are swung together, the insert's recess having a bottom shaped so that when the parts are swung together it cooperates with the top of said post so as to form a swirl chamber having a central discharge orifice and tangential injection orifices with the latter respectively connecting with said holes, the top surface of said plug having a groove in which said tab nests when said parts are swung together and said insert fitting in said cavity so as to permanently hold said parts together.
