An apparatus 100 such as a water gun for dispensing liquid is disclosed. The apparatus 100 comprises at least one liquid dispensing outlet and at least one chamber housing 102 defining at least one chamber for storing liquid to be dispensed through the liquid dispensing outlet. For replenishing with liquid in a fast and convenient manner, the chamber is designed to be substantially uniform in cross section. An opening through which the liquid is adapted to be received in the chamber is also substantially the same size as the cross-section of chamber. A lid 104 is provided that is pivotally movable between a closed position in which at least a portion of the opening is concealed by the lid 104 and an open position in which the at least a portion of the opening is revealed by the lid 104.

In exemplary embodiments of the present invention, Flair® based aerosol-type devices can be provided. Such devices utilize a combination of Flair® technology, pre-compression valves and aerosol like pressurization of the dispensed liquid. Such a dispensing device has 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 reservoir and fills the pressure chamber with that liquid as a user operates the trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve. In a dispensing head a valve is provided to regulate the strength of the flow and preclude leakage. Once the liquid is sufficiently pressurized, it can be dispensed by a user opening an activation valve, such as by pressing on an activation button, and spray can be abruptly stopped by a user ceasing to push on such button. Or, for example, in alternate embodiments without an activation button, once the liquid is sufficiently pressurized, continuous spray occurs until the pressure chamber is emptied. By repeatedly pumping the trigger before the pressure chamber is fully emptied, continuous spray can be achieved. By designing the input volume to be amply greater than the volume of the pressure chamber, continuous spray with fewer pumping strokes can be implemented.

An aerosol-generating system may include a device body and a cartridge configured to be removably inserted into or connected to the device body. The device body may include a power supply and an electrical heater connected to the power supply. The cartridge contains an aerosol-forming substrate in the form of a thermoreversible gel that is a solid at room temperature.

In exemplary embodiments of the present invention, “Flairosol” dispensing devices can be provided. Such devices utilize a combination of Flair® technology, pre-compression valves and aerosol-like pressurization of the dispensed liquid. Such a 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, for example, the inner container of a Flair® bottle, 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, which serve to prevent backflow. Liquid exiting the piston chamber under pressure (supplied by, a user pumping the trigger) enters a central vertical channel which is in fluid communication with both the pressure chamber (above the pressure piston) and a dome valve provided near the outlet channel at the top of the dispensing head. The dome valve has a preset pressure, such that once exceeded by the liquid, opens and allows for a spray. If the liquid pressure drops below such preset pressure, the dome valve closes off the outlet channel, which serves to regulate the strength of the flow and preclude leakage. Alternatively, in an activated embodiment, for example, once the liquid is sufficiently pressurized, it can be dispensed by a user allowing the dome valve to open by pressing on an activation button that removes a dome lock.

A cartridge for a dispensing device, such as a nebulizer, for dispensing a medicament composed of or produced from a plurality of components and a system including a dispensing device, such as a nebulizer, and such a cartridge. The cartridge includes at least two fluidically separated chambers which each contain at least one component of the medicament, an actuating mechanism for fluidically connecting the chambers and mixing the components for the dispensing of the medicament A method for preparing a medicament composed of a plurality of components in a cartridge for the dispensing of said medicament by way of a dispensing device, such as a nebulizer, where a plurality of fluidically separated chambers of the cartridge are fluidically connected, and a component of the medicament is at least partially transferred from one of the chambers to another of the chambers with another component of the medicament in order to mix the components. Only once the components have been mixed is the cartridge opened for the extraction of a dose of the medicament.

A system includes a nebulizer for nebulizing a fluid from a container and such a container containing a fluid and are proposed. The fluid is a non-newtonian fluid, in form of a suspension or emulsion or a liposomal fluid or a gel. The nebulizer includes a fluid pump for withdrawing the fluid in doses from the container and pressurizing the respective doses for nebulization through nozzle channels having a hydraulic diameter in the range of 3 to 20 microns at an operational pressure of 5 to 250 MPa.

In embodiments, aerosol-type devices are provided. The devices have a main body comprising a pressure chamber, with pressure piston and pressure spring, and a piston chamber which draws liquid from a reservoir and fills the pressure chamber as a user performs compression and release strokes. The piston chamber has both inlet and outlet valves. In a dispensing head a valve is provided to regulate the flow strength and preclude leakage. Once the liquid is sufficiently pressurized, it is dispensed by a user opening an activation valve, and spray can be abruptly stopped by closing the activation valve. In alternate embodiments, without an activation valve, once the liquid is pressurized, continuous spray occurs until the pressure chamber is fully emptied. Pumping the trigger before the pressure chamber is fully emptied achieves continuous spray. When the input volume is greater than the volume of the pressure chamber volume, continuous spray with fewer pumping strokes occurs.

Systems and methods for suppressing vaporization of a volatile fluid dispensed from a pressure vessel are provided. The system includes an evaporator coupled in thermal communication with a first flow of volatile fluid from the vessel and in fluid communication with a second flow of volatile fluid from the vessel. The evaporator includes at least one channel for channeling the second flow of volatile fluid therethrough. A metering valve is coupled in fluid communication with the channel and between the evaporator and the vessel. In addition, the system includes a compressor coupled in fluid communication with and downstream from the at least one channel. Moreover, the system includes a return line coupled in fluid communication with an outlet of the compressor. The compressor is configured to compress the second flow of volatile fluid and channel the compressed second flow of volatile fluid to the pressure vessel via the return line.

Hair care device includes: housing including suction port and discharge port; heater disposed inside housing; and spray including two-fluid nozzle that discharges an atomized liquid. Housing includes, inside housing, air blow flow channel disposed between suction port and discharge port, and branch flow channel disposed below air blow flow channel. Heater is disposed in air blow flow channel, and spray is disposed in branch flow channel.
