ABSTRACT:
An apparatus for filling a flexible container with a liquid from a reservoir or tank having a plurality of filling nozzles or tubes. The container engages a nozzle or tube as it is being filled and is subjected to a filling head pressure that causes the sides of the container to distend or expand thus enlarging its volumetric capacity. A control, including a plunger or projector, is provided to engage and indent or compress a side of a container to adjust the volumetric size of the container during the filling operation. Thus, when the head pressure is removed from a filled container, the plunger or projector is moved away from or out of engagement with the side of the container whereby the contraction of the sides of the container will not result in an overflowing or spilling of the contents of the container.
