Abstract: Lotion pump has a stepped piston telescoping inside a stepped body to define a pumping chamber. The piston has in the wall of the piston inlet and discharge apertures, one above the other, to the pumping chamber. A stem integral with the actuator spout has a sealing head inside the piston which shuttles back and forth between positions at which it covers one aperture or the other. Shuttling is implemented by lost-motion between the actuator spout/stem and piston. A spring urges the stem up at all times.

Abstract: A pump dispenser connected to a container of liquid has a first piston reciprocatable in a first cylinder for pumping a quantity of liquid at each depression of the piston. A valve member received within a channel in the first piston is spring biassed into a position in which a dispensing outlet is normally closed and is movable to release liquid in response to excess liquid pressure in the first chamber. A cylindrical extension to the valve member defines a conduit communicating with liquid in the container and is separable from the valve member to open a liquid inlet port for recharging the first chamber. A second piston is movable in tandem with the first piston and cooperates with a second cylinder to provide suction on a return stroke of the pistons which is utilised to remove residual liquid from a dispensing channel delivering pumped liquid to a nozzle. Residual liquid collected in the second chamber is returned to the container during the next subsequent actuating stroke of the pistons.

Abstract: A vertical hollow cylinder has a recess adjacent an upper end and a lower end constituting a throat. A vertical hollow outer piston is slidable in the cylinder with upper section extending above the cylinder and a lower section disposed within the cylinder. The lower section has first and second vertically spaced horizontal extensions disposed in slidable sealing engagement with the cylinder wall and has a third extension in slidable sealing engagement with the throat. The outer piston also has first and second vertically spaced channels extending from the second inner wall into the interior of the cylinder which are disposed respectively above the first extension and below the second extension. A lower variable volume is defined by a portion of the cylinder wall subtended between the second and third extensions and communicates with the second channel. A member is disposed within the recess, in sealing engagement with the upper section of the outer piston and cylinder wall.

Abstract: An actuator for a liquid spray pump is provided with a skirt which co-operates with a body of the pump to compress a volume of air during pump actuation. Air compressed by this action is ejected from an air injection channel in the vicinity of a liquid spray emerging from a first nozzle defined by the actuator. A second nozzle is connected to the actuator externally of the first nozzle to define an air gap therebetween and the air ejection channel communicates with the air gap such that in use both the liquid spray and the compressed air are dispensed through the second nozzle aperture. Primarily intended for dispensing water based products, the effect of the compressed air is to assist in the evaporation of water contained in the liquid or any other volatile liquid dissolved in a liquid product to be dispensed in aerosol form.

Abstract: Pump apparatus for delivering water based formulations as an aerosol spray provides for quantities of liquid and air to be pressurized in separate chambers by pump action. Liquid is dispensed through an orifice via a dispensing channel which in one embodiment is purged during a terminal part of the actuating stroke by the release of air through the dispensing channel. In the second embodiment air and liquid are mixed during the actuating stroke so as to be dispensed together and during a return stroke air is sucked through the dispensing channel to remove residual liquid. The air purging action prevents the build-up of deposits in the dispensing channel and orifice.
