The aerosol filler in Pharmaceutical Industries
In accordance with the present invention, the filling apparatus for charging a pressurized aerosol container with a liquid product utilizes a male injector depending from a liquid reservoir in conjunction with a female valve of the container. The Aerosol Filling Machine is positioned or adjusted between a can non-filing position and a filling position, and pressure selectively draws liquid from the reservoir to the can when in a filling position. A substantially cylindrical housing engageable with and extending from the reservoir has an axial bore for liquid communication with the reservoir. A valve control having a valve body disposed in the axial bore of the cylindrical housing and having a central opening in liquid communication with the axial bore, includes a hollow injector pin extending longitudinally from the valve body and concentrically arranged with the opening of the valve body and terminates with at least one aperture. The valve control is biased to a closed, no-filling position, and when the can is in a filling position the injector pin is adapted to be received by the female valve, thereby establishing liquid communication between the reservoir and the can. A locking nut retains the valve control in the axial bore of the cylindrical housing. When the can is in a filling position, liquid flows from the reservoir and through the axial bore of the cylindrical housing, the valve control, the female valve, the dip tube depending downwardly from the female valve, and into the can.
This invention relates to an apparatus for filling an Aerosol Filler . In its more specific aspect, this invention relates to an apparatus or device for filling an aerosol container having a female valve with liquid product. Aerosol dispensers, which are well known and used in abundance, consist of a self-pressurized and hermetically sealed container of metal, glass, or plastic. Most typically, the dispenser is charged or filled with the aerosol product, e.g., paint, lacquer, enamel, acrylic, fragrance, cleaning agent, etc., and then charged with a propellant and sometimes a solvent; but for a small percentage of dispensers, the container is preloaded with a propellant and sometimes a solvent, and then charged with the aerosol product. The product is dispensed, upon actuating a metering device or actuator, as a spray, foam, lotion, or the like.
Filling the precharged dispenser or container with the Aerosol Filling Machine may be accomplished with an automatic system used in high volume applications, which meters a preselected amount of product into the container, or with a manual system. Regardless which system is used, usually depending upon volume, the apparatus typically includes a can holding means spaced below a reservoir for holding the liquid product. The male valve which is mounted in the cup of the container is brought into engagement with the reservoir outlet, and liquid flows from the reservoir through the valve and a downwardly depending dip tube, and then into the container. In the filling operation, it is important that the amount of liquid for each container must be accurate, that the operation be clean with essentially little or no leakage or overflow, and there be essentially little or no clogging.
