摘要:
A pressurized dispenser includes a base and a peripheral wall having an open end sealed by a dispensing element comprising a dip-tube, a fluid reservoir in contact with the dip-tube for reducing the compressed gas lost from the pressurized dispenser, a compressed gas and a dispensing liquid. In embodiments, a majority of the fluid reservoir may be located outside of the dip-tube, and the fluid reservoir may include a porous material, arranged in use to hold a volume of the dispensing liquid. Such porous material may be configured so that, in use, at least a portion of any compressed gas in the reservoir can be displaced by the liquid, ejecting such portion of the compressed gas into the dispenser. In embodiments, the dispensing element may be configured to dispense dispensing liquid continuously for at least 0.5 seconds, upon actuation of the dispensing element.

Improved therapeutic sclerosing microfoams and methods and devices for making them are provided that have advantage in producing a consistent profile injectable foam with minimal input by the physician yet using high volume percentages of blood dispersible gases, thus avoiding use of potentially hazardous amounts of nitrogen.

Processes and devices for delivering a fluid by chemical reaction are disclosed. A chemical reaction is initiated in a reaction chamber to produce a gas, and the gas acts upon a piston to deliver the fluid. Preferred devices typically include an upper chamber, a lower chamber, a fluid chamber, a piston between the lower chamber and the fluid chamber, and a barrier between the upper chamber and the lower chamber. When the barrier is broken, reagents in the upper chamber and the lower chamber are mixed together to generate the gas.

An aerosol device for dispensing texture material for matching existing acoustical ceiling texture. The device comprises a container, a valve assembly, a dispensing nozzle, a hardenable material, and pressurized inert gas as a propelling mechanism. The hardenable material and pressurized inert gas are placed into the container. When the valve assembly is opened, the inert gas forces the hardenable material out of the container through the dispensing nozzle. The dispensing nozzle diverts at least a portion of the hardenable material exiting the container to develop a spray suitable for the application of the hardenable material onto the ceiling surface being textured. The hardenable material preferably comprises at least water, filler, binder, and polystyrene particles. The inert gas is preferably nitrogen.

A hand-held unit for applying identifying microdots mixed within an adhesive base fluid, comprises a housing which mounts a container for the mixture and a canister of propellant gas. When an outlet valve of the canister is depressed, propellant gas flows from the canister into a nozzle whereby mixture is drawn from the container for discharge through that nozzle for application of the mixture to an article, a vehicle for example, for identification purposes.

摘要:
A valve system adapted for mixing and dispensing separately stored substances is provided. The valve has at least a two-way valve aspect and a one-way valve aspect in selective communication with two or more inner chambers housed in an outer housing. The outer housing preferably stores a propellant that creates pressure in the inner chambers for mixing and dispensing of the substances contained therein.
