摘要:
Le dispositif comprend un récipient (3) muni, en partie haute, d'une ouverture (4) sur laquelle est montée une valve de distribution (11), et une poche souple (9) disposée à l'intérieur dudit récipient (3) pour établir une séparation entre le produit (2) à distribuer et un moyen propulseur (14) propre à maintenir une pression interne suffisante pour la distribution du produit. Le produit actif (2) à distribuer est situé à l'intérieur de la poche souple (9) et la valve (11) est dépourvue de tube plongeur ; une quantité de moyen propulseur (14) est introduite dans le volume (10) du récipient (3) situé autour de la poche souple (9) ; la poche souple (9) est réalisée en une membrane suffisamment perméable pour permettre de maintenir un équilibre de la pression gazeuse du moyen propulseur (14) entre le volume (10) extérieur à la poche (9) et l'intérieur de cette poche (9).

摘要:
The procedure entails the introduction through the mouth of the container of the base product and the propellant, made up of solid CO 2 at -75° to -85°C, and then, clamping the valve onto the container.
摘要:
A system for using aerosols and aerosol packages. As taught by the invention, the system comprises a plurality of aerosol packages composed of a pressure-resistant shell, a resilient container within said shell, a press valve communicating with the space defined by said container, and propellant gas in the space between the container and the shell, and a filling apparatus for aerosol packages, with at least one liquid container, a nozzle suited to open the press valve of an aerosol package, and a force means for transferring liquid into the pressurized package.

A filling apparatus for, a filling system for and a method of introducing into a container a suspension or solution of a substance, in particular a pharmaceutical substance, in a propellant under pressure, the filling apparatus comprising: a main body (4) including a passageway (20) having an inlet opening (21) and first and second outlet openings (25, 22), the first outlet opening (25) communicating, in use, with a valve stem (144) extending from a head (141) of a body (139) of a container (138); a fill actuator (7) in communication with the inlet opening (21) of the passageway (20) comprising a filling valve assembly (29) for selectively introducing propellant under pressure containing a substance in a suspension or solution into the passageway (20); an exhaust actuator (10) in communication with the second outlet opening (22) of the passageway (20) comprising an exhaust valve assembly (48) for selectively exhausting propellant under pressure containing substance from the passageway (20) and including at least one exhaust gas conduit (84, 92, 93) having an outlet (86, 94, 95) configured so as, in use, to provide a flow of exhaust gas substantially aligned with a flow of propellant containing substance from the second outlet opening (22) of the passageway (20); and a container-engaging body (16) for receiving, in use, the head (141) of the body (139) of the container (138) which includes the valve stem (144).
摘要:
To permit aerosol generation apart from the restriction of rules and regulations, the aerosol generation being easy, ready, free from adverse effects on the environment and such that a mother substance is sprayed uniformly. Mother substanse (4) is dissolved uniformly in environment-safeguarding liquefied gas (5) by sealing these substances in a small size, high pressure gas cartridge (1) of 100 cc or below. The cartridge (1) is opened to spray the mother substance (4) together with the environment-safeguarding liquefied gas by making use of the pressure of gasification of the liquefied gas (5). The liquefied gas is liquefied carbon dioxide or nitrogen suboxide gas. The mother substance (4) is charged directly if it is soluble to the phase of the environment-safeguarding liquefied gas (5). If the mother substance is a physically insoluble chemical substance, it is dissolved in a solvent, a fat, etc. using a dispenser before charging. If the mother substance is powder, it is commuted to 0.5 µm or below for suspension. The small size, high pressure gas cartridge (1) may be sealed by mounting a constant quantity valve in an opening (6) of the small size, high pressure gas cartridge.
摘要:
A method of filling a container with a product. The container may be pressurized. An outer container (12) is provided. Product and/or propellant is disposed in the outer container. An inner container (16) is disposed in the outer container. The inner container expands upon the insertion of product and/or propellant therein. This expansion provides for pressurization of the contents of the outer container, which pressurization is useful for dispensing the contents of the inner container, and/or outer container. This method may be performed in a variety of sequences.
