Abstract: A valve for an aerosol container has a valve plate adapted to close an axial end of the container, a valve subassembly having at least one dispensing element, a seal ring, and a compression spring, and a valve holder containing the valve subassembly and having an axially open assembly hole through which the valve subassembly can pass. A cover closes the assembly hole and is formed with an axially throughgoing cover hole through which the dispensing element projects and with which the dispensing element forms an annular and axially extending passage. A seal ring surrounds the dispensing element and is engaged between the holder and the cover. A spring biases the dispensing element axially outward against the seal ring and presses an axial outer face of the seal ring against the axially inner face of the cover. Passages extend axially between an interior of the container and the seal ring.

Abstract: An aerosol container has a mouth centered on an axis. A plastic valve plate is fitted to and tightly attached to the mouth and has a disk formed with an outlet centered on the axis. An outlet valve is carried on the valve plate and has a housing holding a movable valve element. A rigid extension is integrally formed on the disk around the hole, projects axially into the container, and forms a cavity in which the housing of the valve is fitted. A seal is fixed in the cavity between the housing and a surface of the extension forming the cavity.

Abstract: An aerosol container comprises a can having an open end. A valve disk fitted to the open end is made of plastic and has a center part formed with a throughgoing hole defining an axis. A plurality of fingers extend axially from an inner face of the center part around the hole into the can and each have an inner end formed with a radially inwardly projecting barb spaced axially from the inner face. A dispensing valve has a tubular valve housing fitted between and gripped by the fingers and having an axially inwardly directed face on which the barbs bear axially outward. A seal is compressed axially between an outer end of the valve housing and the inner face of the disk around the hole.
