Abstract

A method and apparatus for dripless filling of liquid material within containers wherein a filling nozzle is moved downwardly or the container is moved upwardly until its shroud engages the upper end of the container and positions its nozzle into the container. After transferring a measured volume of liquid into the container, the filling head is moved upwardly out of contact with the liquid and vacuum is applied immediately at the lower tapered tip of the dispensing nozzle to recover any drippage descending downwardly to the point of the tip. Simultaneously with its withdrawal from the container, residual liquid is wiped from the external tubular member into the container, leaving only a small quantity of residual liquid on the tapered tip which is easily recovered by the vacuum system. The recovered drippage is transferred by the vacuum system to a vacuum chamber and is then selectively transferred from the vacuum chamber to a supply chamber for subsequent filling operation.
