Abstract
A container having an actuating mechanism with a depending flexible central stem is filled with a flowable viscous substance by the method disclosed. In the method, the container is disposed with its open end facing upwardly for receiving the lower end of a filling tube having a camming surface which engages the stem and displaces it laterally as the filling tube enters the container and advances alongside the stem. After the filling tube reaches a predetermined depth, discharge of the viscous material begins and continues as the filling tube is withdrawn from the container.
Claims9
A method of rapidly flowing a viscous substance into a container having at one end an actuating mechanism and a depending flexible central stem terminating adjacent an open opposite end of the container without forming substantial air pockets at said one end, said method comprising the steps of:
- disposing the container with its open end facing upwardly,
- advancing relative to the open end of the container the lower end of a filling tube,
- engaging the filling tube laterally against the stem and displacing it toward a side of the container,
- inserting the filling tube lengthwise in the container to a predetermined location,
- at said location initiating the discharge of the viscous substance into the container laterally of the stem for displaciing air laterally and axially out of the container, and
- withdrawing the filling tube from the container while simultaneously discharging the viscous substance therefrom and thereby continuing to discharge air axially out the open end of the container, whereby the container can be filled rapidly without forming substantial air pockets adjacent to its one end.
