An improved screw-on assembly for coupling line connectors with spouts has been invented. The invention can be used with bag-in-box packaging or with a variety of other applications requiring fluid coupling. In one embodiment, threading is accomplished by mating internal threads on a line connector with flexible tabs located on the spout. Deformation of the tabs during threading provides a restorative force that stabilizes the assembly during threading. Cooperation of the deformable tabs with structures near the end of the thread provides for self-locking of the assembly. In addition, the tabs are situated on a flange, providing compatibility of the present invention with prior art line connectors.

A spout for a flexible bag adapted to hold a liquid, the spout adapted for coupling with a connector having a rotatable spout adapter with an internal thread. The spout has a substantially cylindrical body with an outer surface, a spout opening, and a spout axis. The spout further has at least one flexible tab attached to and protruding radially distal from the outer surface of the cylindrical body of the spout. The tab has a top side that is substantially perpendicular to the spout axis, a bottom side opposing the top side, and a leading edge for engaging the thread. Additionally, the spout, has an undeformed tab length that typically deforms upon engaging the internal thread of the spout adapter.

A fitment for a flexible container and method of using the same, especially suitable for use with a dispensing system having a peristaltic pump. The fitment having a generally cylindrical base assembly and an outlet port for providing access to the contents of the container, and a spout body dimensioned to attach to the base assembly to form a fluid flow path between the base assembly and spout body. A cap and barrier material may also be provided to seal the outlet port of the container and protect against contamination.

In a bag-in-box fluid dispensing system including a bag fitment sealed over an opening in the fluid bag, a normally closed valved intermediate element sealed in the bag fitment, and a normally closed valved dispenser removably coupled to the valved intermediate element, the intercoupling of the intermediate element and the valved dispenser causing the valves in each unit to open for the passage of fluid from the fluid bag, an improved intermediate element having but two components, the improved element including a housing having a long skirt for passing through the bag fitment and into the fluid bag to prevent blocking of the bag opening, a valve set formed by the deformation of a circular opening in the end of the housing, and a normally closed axially movable valve member for mating with the valve seat and having a valve spring bias provided by the deformation of a novel hemispherical resilient member latched in the bore of the housing.

A machine for automatically filling plastic bags with liquid or particulate material moves a continuous web of such bags through a number of serially positioned work stations. The bags are completely sealed when they enter the machine. As each bag passes through a slitting work station, a specially shaped opening is cut into the bag near an end of it which will become its top. When the bag proceeds to a filling work station, it is held vertically and a specially shaped fill nozzle is moved downward and rotated for entry into the bag through the slit opening. A valve is provided within the fill nozzle for controlling entry of the material into the bag. The valve and fill nozzle are cooperatively controlled by a single mechanism. The bags are transported through the various work stations by a positive toothed belt drive that preferably holds the bags flat until the filling station, wherein the belts are then moveable toward and away from each other in order to allow filling of the bag. After filling, the bag opening is then sealed.

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.
