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.

Abstract: The embodiment of the invention are directed to a dispenser assembly having a reservoir bottle with an opening for fluid communication. The opening is formed to receive a housing cap and a dispensing pump such that the dispensing pump is sealingly engaged to the bottle opening. The housing cap has an outer surface in contact with the reservoir opening and an inner surface in contact with the dispensing pump. The outer surface includes a lip which engages the reservoir opening and a step which engages the pump.

Abstract: The invention relates generally to a foam dispenser having a reservoir, a housing, and a chamber. The reservoir delivers fluid to the housing and the chamber through a dip-tube. The chamber moves within the housing in response to fluid pressure or air pressure from the reservoir, allowing air and foamable liquid to enter the chamber. Foam-producing packing material inside the chamber causes the air and foamable liquid to mix and produce foam.

Abstract: A spray dispensing head for a squeeze dispenser is disclosed. The dispensing head includes passageways for directing streams of air and liquid to a mixing chamber wherein the liquid is broken up into droplets and emitted as a fine spray through an orifice. The device includes a valve which is operated by a push-pull motion. When the valve is closed, the liquid is sealed off from the atmosphere, thus preventing drying or contamination of the liquid product.

Abstract: A dispensing head for a squeeze bottle sprayer includes a rotatable valve. The rotatable valve has both an air control notch and a fluid control notch. Upon rotation of the valve, the notches cooperate to vary the amount of air and or fluid discharged by the dispenser. The density of the stream may therefore be varied.
