Abstract: A pumping device (100), comprising a movable part and a fixed part. The movable part is capable of reciprocating relative to the fixed part, thereby dispensing, by means of a straw (30) connected to the fixed part, a product contained in a container (20). The pumping device (100) comprises elastic members (150, 250, 350, 550, 650, 850, 950, 1050), one end of each of the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) is connected or supported on the movable part, and the other end of each of the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) is connected or supported on the container (20), or is supported on the container (20) by means of the fixed part. The pumping device (100) having the described structure allows the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) to be fabricated using plastic, and is also capable of obtaining the required elasticity.

Abstract: Dispensing devices are provided. Such devices utilize a combination of Flair® technology, pre-compression valves and aerosol-like pressurization of the dispensed liquid. An example dispensing device has, for example, a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring. The device further has a piston and a piston chamber which draws liquid from a container and fills the pressure chamber with that liquid as a user operates a trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve. Liquid exiting the piston chamber under pressure enters a central vertical channel which is in fluid communication with both the pressure chamber and a dome valve, with pre-defined opening pressure, provided near the outlet channel at the top of the dispensing head.

Abstract: A pump dispenser having a bottle with a neck and a pump assembly. The pump assembly includes an actuator, a closure connected to the actuator and coupled to the neck of the bottle, a dip tube, and a dual chamber pump. The dual chamber pump includes a piston assembly, a sealing cap, and a housing, which includes a pump chamber, a storage chamber having a cavity, and a core. The sealing cap is rigidly connected to the core and closes the storage chamber at a lower portion such that the substance to be released remains stored in the storage chamber cavity. When the actuator is pushed down for a first time by a user, a piston assembly moves to push down a connecting stem, which pushes down the sealing cap to open the storage chamber for releasing the substance contained in the storage chamber from the bottle.

Abstract: Disclosed herein are devices, systems, and methods for dispensing fluids. One general aspect includes a multi-chamber fluid dispenser. The multi-chamber fluid dispenser includes a container and a cap. The container has a plurality of chambers formed therein. Each of the chambers in the plurality of chambers is configured to store fluid therein. The cap is for covering the container. The cap includes a distributor through which fluid stored in any one of the chambers in the plurality of chambers is allowed to be expelled from the container Each of the chambers in the plurality of chambers is configured to be in fluid communication with the dispenser such that fluid is dispensable from the container in at least one of the following manners individually as an individual fluid and together as a mixed fluid.

Abstract: Hand dispenser for cleaning, disinfectant and/or perfuming liquid products, of the type including a container having a dispensing button which operates a piston of a piston pump for dispensing liquid product from a nozzle, and a seat for a refill including a bottle containing a sprayable liquid formulation, the piston pump being indifferently housed in the container or in the refill. The container includes a cover hinged on the container, for closing the seat of the refill, and a mechanical coupling between the cover and the dispensing button, which causes the dispensing button to raise beyond its ordinary rest position, when the cover is opened, and to lower to its ordinary rest position, when the cover is closed.

Abstract: A container having a pressurized chamber containing a fluidic material and a dispensing assembly coupled thereto. The dispensing assembly includes a dispensing passageway for discharging the fluidic material from the container. A dispensing valve, a tilt valve, and a pump assembly are all operably coupled to the dispensing passageway. The tilt valve is alterable between a closed state in which the pressurized chamber is scaled and an open state in which the dispensing passageway is fluidly coupled to the pressurized chamber. The pump assembly is alterable between a first state in which a variable volume of the dispensing passageway in at a first volume and a second state in which the variable volume is at a second volume that is less than the first volume. Thus, the pump assembly creates a negative pressure behind the dispensing valve to prevent excess fluidic material from being dispensed.
