ABSTRACT:
An assembly for filling and sealing a cavity (14) in a container (10). The assembly includes a fill passage (18) in sealing engagement with the periphery of the receiving passage (12) in the container (10). A vacuum source (24) withdraws gas from the container (10) and the assembly. Powdered material under a vacuum is supplied to a vibrating platform (44) which dispenses the material while vibrating so that the material passes through a valve (48, 52), the fill passage (18) and into the container (10). A plug magazine (26, 125) stores and delivers one spherical ball (28) at a time to the fill passage (18) for being forced into the receiving passage (12) to seal the container (10). A vacuum valve (48, 52) seals the material supply from the fill passageway (18) to maintain the vacuum in the material supply when the container (10) is received. A probe (74) has a thermistor at the lower end which changes resistance in response to a change in temperature which occurs upon the material level in the container reaching the lower end of the probe (74), in response to which the vibration of the material supply platform (44) is stopped. The probe (74) is retracted and the snout (68) is moved downwardly to force a ball (28) into the receiving passage (12) to seal the container (10). The vacuum valve (52) is closed, the source of vacuum is closed and the sealed container (10) is received and replaced by another empty container.
