Abstract:
The invention provides a method for assembling a dispensing system (1) for dispensing a fluid medium under pressure, the method including : providing a valve cup (10) including a valve (50) and a bag (100), the valve (50) configured to attach to an opening of the bag (100), wherein the valve cup (10) is either formed from a first plastic or includes a lining (70) formed from the first plastic; inserting the valve (50) into the opening of the bag (100) and fluidly sealing the bag (100) to the valve (50); providing a container (30), the container (30) including an opening (32) and suitable for storing a fluid medium under pressure and formed, at least in part, from a second plastic; inserting the bag (100) into the container (30) and positioning the valve cup (10) at the opening (32) of the container (30); pressurising the internal volume of the container (30); and welding the valve cup (10) to the container (30) to thereby provide a seal between the valve cup (10) and the opening (32) of the container (30).
Abstract:
This invention relates to apparatus and devices that generate sclerosing microfoams for the treatment of venous disorders, such as varicose veins. The invention includes adaptors which provide fluid connections to microfoam generating devices, to enable filling with gas and/or dispensing of the microfoam produced. The adaptors are generally cylindrical elements with open ends to enable attachment to pressurisable container on one end and are configured to enable rapid and easy attachment of a filling means or a dispensing means through the other end of the adaptor. A particular configuration comprises three or more circumferentially and downward extending cam tracks which cooperate with corresponding cams on the filling means or dispensing means and which connect a pressurisable container to a fluid path of a filling or dispensing means when the pressurisable container and filling or dispensing means are rotated relative to each other.
Abstract:
A valve assembly for a pressurized container includes a valve stem and a mechanical seal. The valve stem has an open top portion, a closed bottom portion, at least one primary radial opening, at least one secondary radial opening and a valve stem passageway between the open top portion and both the at least one primary radial opening and the at least one secondary radial opening. The mechanical seal comprises a longitudinal passageway that seals the at least one primary radial opening and the at least one secondary radial opening, respectively, when the valve stem is in a closed position. Longitudinal translation of the valve stem exposes the at least one primary radial opening or both the at least one primary radial opening and the at least one secondary radial opening to the pressurized container when the valve stem is in an open position.

Abstract:
A pressurized dispenser comprising a base around which surrounds 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, wherein a majority of said fluid reservoir being located outside of the diptube and the fluid reservoir comprises a porous material, arranged in use to hold a volume of the dispensing liquid, the porous material being configured so that in use at least a portion of any compressed gas in the reservoir can be displaced by the liquid, ejecting said portion of the compressed gas into the dispenser, and wherein the dispensing element is configured to dispense the dispensing liquid continuously for at least 0.5 seconds, upon actuation of the dispensing element.
Abstract:
An aerosol valve having a valve stem and compression spring geometry that create shorter flow paths, have fewer changes in flow direction, and passageways with large cross-sections to reduce resistance and back pressure is disclosed. The aerosol valve minimizes agglomeration of solids in the flow paths and reduces product failures. A method of using the aerosol valve is also provided.
Abstract:
The invention relates to a container assembly (1) for liquids, such as beverages and oils, comprising a container (2), chimes (4, 6B) and a valve assembly (3) for feeding a propellant to and dispensing the liquid from the container (2). Ά portion (4) of the assembly (1) has a polygonal cross-section, which cross-section at least partially circumscribes the cross-section ( s ) of the remainder of the assembly (1).
Abstract:
A method of pressurizing a container usable for an aerosol dispenser. The method comprises providing a pressurizeable outer container and complementary valve cup, at least one having a channel into the container. A manifold is brought into sealing relationship with the channel of the container. Propellant is supplied from the manifold, goes through the channel and into the container. While the manifold is still sealed to the container, the channel is sealed shut to maintain the pressure. Sealing may be accomplished by sonic or ultrasonic welding.
Abstract:
An inhaler including a pre-inserted cartridge (100) is proposed. The cartridge contains liquid (103) which is preferably pressurized to a low pressure. The cartridge is connected via an aerosol valve (106) with the inhaler. The liquid is further pressurized by a pump (117) of the inhaler to a high pressure and atomized.
Abstract:
Distributeur de produit fluide sous pression comprenant un bidon externe (1), une poche souple interne (2) contenant du produit fluide F, la poche étant disposée dans le bidon (1) de manière à définir un espace intermédiaire E destiné à être rempli avec un gaz sous pression G de manière à exercer une pression sur la poche souple, une valve (3) montée sur une ouverture (21) de la poche (2), la valve comprenant un élément mobile (32, 34) actionnable de manière à permettre au produit fluide sous pression d'être distribué à travers une sortie (321) de la valve, le distributeur comprenant des moyens d'obturation (5 ; 5' ; 5'') aptes à obturer le passage entre la poche et la sortie de valve, indépendamment de la pression au niveau de la sortie de valve et/ou de l'actionnement de l'élément mobile.
