A spout fitment attached to a liquid filled bag, or other fluid container, of a type having a slidable dispensing valve member to receive a line connector for establishing a fluid path from an interior of the container, through a valve element in the line connector and into a service line attached to the line connector. Although the dispensing valve member is slid into the container when the line connector is inserted therein, the sliding motion does not form the container valve action. The container seal is established by a valve element within the slidable dispensing valve member that is resiliently biased to close an opening therein. The dispensing valve member thus need not be slid in the fitment when the line connector is removed from the dispensing valve member, thereby making it easier to remove and reinsert the line connector. Insertion of the line connector within the dispensing valve member causes their respective valve elements to engage each other to open and form the fluid flow path.

In a combination of a service line connector including a first valve member therein which is resiliently loaded to normally close off an end opening thereof and having a mechanism outside of said end for removable attachment to a spout fitment that is carried by a container and which includes a dispensing valve member held therein to receive the connector end for establishing a fluid path from an interior of the container to a service line attached to the connector, said dispensing valve member, comprising: a shell having first open end into which the connector end is inserted, a wall extending thereacross a distance from the shell first end which includes a fluid opening therein, and an outside surface carried by the spout fitment in a manner that the shell is slidable with respect to the fitment from a first position outside of said container to a second position extending into the container, a second valve member extending through said wall and having one end terminating in a probe facing toward said shell first end and including a sealing element on a side of said wall opposite to said shell first end that covers said fluid opening when said second valve member is urged toward the shell first end, said probe being positioned and dimensioned to be inserted into said connector end to open its said first valve member when the connector end is inserted into the shell first open end, means positioned within said shell for resiliently urging said second valve member toward said shell first end in a manner to normally cover said fluid opening with said sealing element when the connector end is removed from said shell first open end, and a surface as part of said shell that is complementarily shaped with said connector end for causing said shell to slide from its said first position to its said second position as the connector end is urged into said shell first end with the first valve member and second valve member probe contacting each other.
