Abstract
A dispensing assembly has a ferrule and collar for maintaining a coupling of a dispensing module to a receptacle neck. The ferrule has an annular plastic skirt open on one end, and plastic nibs extending radially inwardly from the skirt inner surface. The skirt outer surface is a regular polygon with flat surfaces between corners. The collar has a Nomar edge defining an annular recess adjacent the open end with an annular face facing the collar other end. At least the corners of the skirt open end extend radially outwardly into the annular recess of the collar inner surface when the dispensing assembly is secured to the receptacle to retain the collar on the ferrule while the dispensing assembly is secured to the receptacle by the ferrule nibs beneath the flange of the receptacle neck. Installation involves pushing the collar and ferrule onto the receptacle neck with the collar in a raised position on the ferrule, and then pushing the collar down relative to the ferrule.
