Abstract: A pump assembly for a pump dispenser, the pump assembly comprises a cap having a housing and a spout, a collar, a sleeve, and a dip tube. The sleeve is at least partially positioned within the collar and comprises a coupling member. The coupling member comprises a shoulder, a coupling joint, and a coupling member channel extending from the shoulder to the coupling joint. The dip tube has a first end and an opposing second end, and defines a dip tube channel extending from the first end to the second end. The first end of the dip tube is configured to pivotally couple to the coupling joint and fluidly connect the dip tube channel and the coupling member channel. The dip tube channel comprises a first diameter at the first end and second diameter at the second end that is different than the first diameter.

Abstract: A fluid dispenser valve for assembling on a fluid reservoir, the valve including a valve body containing a metering chamber, and a valve member that is slidable in leaktight manner in the valve body between a rest position and an actuated position, the valve body containing an inlet passage enabling the metering chamber to be filled with fluid, the valve body including a closure element that co-operates with the inlet passage, the closure element being movable between an open position in which the inlet passage is open, and a closed position in which the inlet passage is closed at least in part.

Abstract: The technical field is that of simultaneous dispensing of viscous materials. Many compositions comprise viscous components which must be kept separate until they are used. Known methods of application of separate components do not guarantee proper ratios. This invention solves this problem by presenting a single aerosol container (4) having a multi-valve body (8) wherein the valves (10, 12) are activated by a single actuator (26) and the viscous materials are kept separate until used. The system (2) may use multiple collapsible bags (16), a barrier liner (42), a dip tube (46), and a spray-any-direction valve (50) having an omnidirectional attachment (60) which contains a check valve container (122) made up of a constricted lower end (132), a top surface (134), a lateral opening (136), and a check ball (138) for opening and closing passageways.

Abstract: The invention is directed to a valve for an aerosol container for dispersing a suspension or solution of a medicament in a liquid propellant contained therein. The valve comprises a valve body defining an aperture, a seal mounted at the aperture, and a valve stem having a dispensing passage. The valve stem being slideably moveable through the seal such that in a first position the valve is closed to prevent the medicament and propellant from entering the dispensing passage. The valve stem also being such that in a second position the valve is open to allow the substance to be dispensed through the dispensing passage. The valve stem characterized in that it is constructed from a mouldable plastic and a mouldable lubricant.

Abstract: A device enabling a fluid dispenser to operate both in the upside-down position and in the rightway-up position, the dispenser comprising a fluid tank, and a dispenser member having an inlet and a dip tube, said device having a chamber in communication with said inlet of the dispenser member, said chamber having a top inlet and a bottom inlet that are selectively closable by respective top and bottom check valves, the top check valve having a moving valve element suitable for closing the top inlet of the chamber in the rightway-up position, wherein the bottom check valve has a moving valve element that floats, being of a density that is lower than the density of the fluid, and being adapted to close the bottom inlet of the chamber in the upside-down position when the chamber is filled with the fluid.

Abstract: A dispenser includes a container defining a main reservoir for holding a liquid product; a nozzle assembly connected to the container for dispensing liquid from the container; and an inner tank member disposed in the container and defining an active reservoir for holding the liquid product. The inner tank member includes an inlet communicating the active reservoir with the main reservoir, and the nozzle assembly is communicated with the active reservoir.
