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.

An aerosol foam dispenser for dispensing a foam antiperspirant or deodorant composition. The foam dispenser can have a pressurized container adapted for one or more propellants and a liquid deodorant or antiperspirant composition; a valve assembly, which can be a metered valve assembly, having a valve stem; an actuating mechanism in operative communication with the valve assembly, a dome with a skin contacting surface and one or more exit orifices in fluid communication with the valve stem; and a dip tube.

A spray nozzle chip is presented having: a first layer provided with a first layer orifice, a mechanically flexible nozzle layer provided with a nozzle orifice, the spray nozzle chip having a valve functionality obtained by movement of the nozzle layer relative to the first layer due to pressure changes, wherein the nozzle orifice is closed when the nozzle layer is in a default non-pressurised state and wherein the nozzle orifice is opened and set in fluid communication with the first layer orifice when the nozzle layer is deformed due to pressure during a spraying operation, and wherein the spray nozzle chip further has a sealing layer configured to rupture when the nozzle layer is deformed due to applied pressure during a spraying operation.

A dispensing head for a system for dispensing a product, having a body having a well for mounting the head on a tube for the pressurized supply of the product and a recess in communication with the well by means of a dispensing path. The recess being equipped with a nozzle delimiting a dispensing space between the path and a discharge passage formed in the nozzle. The nozzle being equipped with an insert that has a membrane forming, in the space, a communication interface between an upstream part in which the path emerges and a downstream part that supplies the discharge passage. The membrane being reversibly deformable by the product exerting pressure coming from the upstream part, between a resting state in which the size of the interface is minimal and a stressed state in which the size of said interface is increased in order to provide dispensing.

An atomizer device for atomizing a liquid under increased pressure, comprising an atomizer body 14 with one or more atomizing openings from which a mist formed from the liquid escapes during operation. The device comprises a valve device 20, 30 upstream of the atomizer body. The valve device 20, 30 comprises a valve cavity 31 with a valve body 32 and a spring chamber 21 in which spring means 22 are compressible counter to a spring tension. The valve body 24 receives the liquid in valve cavity 31 with a first operative cross-section D1, which first operative cross-section is smaller than a second operative cross-section D2 of spring chamber 21 in which spring means 22 are compressible.

The invention relates to a pump head (I) with a specially designed flexible valve (20) which securely connects the pump head. The valve ensures the pump head is securely closed. The invention also relates to a metering device which can be designed, for example as a squeeze bottle, as a non-airless system or as an airless-system. Said metering device comprises the claimed pump head.

A propellantless aerosol fluid dispensing system including a reusable pressurizable canister and a disposable fluid containing pouch, the pouch including a valve assembly for dispensing the fluid.

A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.

The present invention relates to a spray device, comprising a spray nozzle body (2) and a substantially planar membrane layer (6) suspended over a nozzle cavity (3) to generate microjets, especially for pharmaceutical applications, in particular preservative free formulations. The nozzle body (2,8) contains a microbial barrier, particularly a microvalve (23,24) between a fluid supply channel (9) and said cavity (3).
