摘要:
A valve assembly 200 including a housing 202 with an internally projecting lip 226 that seals against an outer surface of a valve stem 220 inserted through it. A gas inlet 234a is provided above the lip 226 and a liquid inlet 212 is provided below the lip. The lip 226 thus ensures that a gas flow path and a liquid flow path are kept separate until the valve stem 220 is moved to an open position, at which point a liquid inlet hole 284 in the stem is brought into communication with the liquid inlet 212 in the housing and a gas inlet hole 286 in the stem is brought into communication with the gas inlet 234a in the housing for the fluids mix in an outlet conduit 280 in the stem. The arrangement means that there is no contact between the liquid and a sealing gasket 260, thereby avoiding swelling of the gasket that can cause the stem 220 to stick.

An aerosol spray product dispensing device is illustrated, wherein the body or cap of the dispenser is formed by molding polypropylene or other plastic materials employing a step of molding the main body, followed by a step of compressing to fix the nozzle fan -dispensing fan which belongs to the first molding in its housing on the main body and then a second molding applies the dispenser button, usually of different color and different material and/or of the same material, to obtain a finished dispenser part. The dispensing element is practically finished with no need of welding operations of any part thereof.

Provided is a nozzle cap for aerosol container that can be used for cleaning a nozzle of an aerosol container that has a plurality of stems, and preventing the nozzle from being pushed down. The nozzle cap includes a plurality of bar-like pieces 11 that can be inserted from ejection ports 24 of a nozzle 20 into ejection-side communication passages 23a at least until distal ends 11a reach upper ends 22d of stem-like communication passages 22a, and a lower protrusion 14 that prevents the nozzle from being pushed down by abutting on a cover member 30 below ejection tubes 23 of the nozzle 20 when the bar-like pieces 11 are inserted into the ejection-side communication passages 23a.

A delivery nozzle (100) for aerosol and solvent includes a nozzle body (102) defining an aerosol passage (104) and a solvent passage (106) therethrough. The aerosol and solvent passages (104, 106) each extend from an inlet end (108) of the nozzle body to an outlet end (110) thereof. The nozzle body (102) can include a solid, unitary structure with the aerosol and solvent passages (104, 106) both defined through the solid, unitary structure. The inlet end (108) of the nozzle body can include a mounting flange configured to mount the nozzle body in a device for delivering aerosol through the aerosol passage (104) and for delivering solvent through the solvent passage (106). The solvent passage (106) can define a smaller cross-sectional flow area than that of the aerosol passage (104).

Apparatus and methods for delivering medicament. The apparatus may include a fitting (110) for a fluid dispenser. The fitting (110) may include a detent (218) that is configured to limit insertion of the dispenser into the fitting (110) by contacting a terminal surface of the dispenser; and a seal for sealing against the surface. The apparatus may include an insert (102) for the fitting. The insert may include a gasket (204) to seal against the terminal surface of the dispenser; a proximal rim (208) to engage a lateral wall of the dispenser; and a connector (206, 207) fixed to the gasket (204) and the rim (208). The apparatus may include a coupler to engage a pre-filled dispenser; and a body (211) defining a passageway that is configured to be placed in fluid communication with the dispenser. The apparatus may include a dispenser that includes a detent and a seal (Fig. 13). The detent may limit insertion of the dispenser into a fitting.
摘要:
The present invention provides an aerosol device comprising: —a container containing: —one or more propellants, and —a composition comprising one or more fixing polymers and/or one or more styling powders comprising one or more water-insoluble inorganic compounds, the propellant or propellants possibly being present in the composition or in the container, separate from the composition, —a means for distributing said aerosol composition, comprising a diffuser having at least three spraying apertures for spraying the composition in a main spraying direction. The invention further provides a method for shaping the hair and/or maintaining the style, comprising a step of applying to the wet or dry hair a cosmetic composition sprayed from a specific aerosol device.
摘要:
A multi-chambered bottle includes first and second chambers, a metering stage, a pour spout and a cap. The metering stage includes first and second metering stage sections connectable to respective mouths of the first and second chambers. Each metering stage section comprises a nozzle having a liquid inlet orifice and a liquid outlet orifice, and a vent tube having an air inlet orifice and an air outlet orifice at opposite ends of the vent tube, the air inlet orifice to be disposed outside of the respective chamber and the air outlet orifice to be disposed inside of the respective chamber, the vent tube disposed relative to the nozzle such that a line crossing a center of the air inlet orifice and a center of the liquid outlet orifice forms an acute angle with a normal axis of the bottle.
