1,002,464. Filling and closing aerosol containers. NOVIMA A.G. April 3, 1964 [April 4, 1963], No. 13968/64. Heading B8T. In a filling and capping apparatus, an aerosol container 8 is pressed against the underside of a filling head 11, a closure or valve 13 is dropped into a longitudinal channel 12 but is prevented by balls 14 projecting into the channel under the action of springs 15 from dropping down as far as the container, liquid is introduced into the container under the closure by a filling device attached by a valve 36 to a metering pump 37, a plunger 17 then descends and pushes the closure on to the container, and finally closing instruments 43 press the closure periphery under the thickened container lip. The filling device may comprise a movable filling pipe 28 or alternatively may comprise one or more ducts 124, Fig. 3. A table 107 or other support 7 on which the container is raised to the filling head, the filling device, the filling valve, the plunger 17 and the closing instruments all may be actuated by pneumatic piston and cylinder motors. The closing instruments may move vertically within the longitudinal channel and be in the form of a tool 131, Fig. 3, having its bottom end divided into segments which when forced against the closure periphery force the same over the container rim. A plurality of such filling heads may be fitted above an indexing table which rotates about a shaft through which the filling liquid enters the metering pump. The closing instruments may move together with the filling head, or the filling heads may move separately to a position where they align with a closing device.
