Flexible container with displaceable fitting and probe coupler apparatus

The combination of a closure fitment, a seal plug, and a probe connector for use with a disposable container;

• said closure fitment comprising a hollow body having a portion attachable to a wall of the container and having a passageway therethrough providing communication between the exterior and interior of the container;
• said seal plug comprising a body which is movable within said fitment to an opened position;
• first aperture means acting between said closure fitment and said seal plug and being effective when said seal plug is moved to said opened position to provide communication between the interior of the container and the interior of the seal plug;
• said probe connector comprising probe means, probe adapter means and manually rotatable probe actuating means which is separable as a unit from said fitment;
• said probe adapter means comprising a body which is detachably connectible to said closure fitment;
• said probe means comprising a hollow tubular body having means for connecting to an external delivery tube and being slidably journaled within said probe adapter means and axially movable between opened and closed positions;
• second aperture means associated with said probe adapter means, said probe means, and said seal plug, said probe means being effective when moved to its said opened position to provide communication between the interior of said container and the interior of said probe means through said first and second aperture means, said probe means being effective when moved to its said closed position to close said second aperture means to prevent back flow from the delivery tube when the probe connector is disconnected from the closure fitment;
• and
• said manually rotatable probe actuating means comprising a tubular body having means connecting it with said probe means and said probe adapter means respectively to move said probe means between its said opened and closed positions in response to rotation thereof.
