Abstract: A container for use in a closed application system includes a valve mounted to a discharge opening of the container and rotatable with the container for controlling the discharge of material from the container. The valve includes an element for engaging corresponding structure in a receptacle for receiving the contents of the container. The element engages and locks the valve in the receptacle when the valve is opened and the contents are being discharged from the container into the receptacle. The valve element and the corresponding structure on the receptacle cooperate so that the container can only be received in and removed from the receptacle when the valve is closed. In this manner, the contents in the container can be discharged only when the container is received within the receptacle and the container is rotated in a direction to open the valve.

Abstract: A delivery system for dispensing controlled amounts of liquid or powder has two slidingly engaged parts which are held together as a single unit.

Abstract: 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.

Abstract: Problems of filling dunnage bags for cushioning loads in transit in trailers, railroad cars, and the like, with air are resolved by this improved air filling bag valve and nozzle. In several respects the valves are superior in operation, wasting less air and filling time, and are less tiring for operators to use. For example, this nozzle simply slides laterally into place on the dunnage bag valve stem and locks itself there for hands off filling without manual pressure to press the nozzle axially against dunnage bag valve stems to open them, which is fatiguing with arms outstretched in the crowded spaces available. Damage is reduced that may result to dunnage bags when the filling nozzles are removed against the pressure of adjacent filled dunning bags and are withdrawn. These nozzles are simply pulled out laterally by the attached hose.

Abstract: A two-part coupling structure includes a male coupling part and a female coupling part which are mutually engageable to open fluid communication between a fluid-storage vessel and a conduit, for example.

The retention volume of fluid which is trapped between the connected male and female coupling parts and which is exposed to or lost to ambient when the coupling parts are disconnected is very small. The male coupling part is carried in a guide structure which is removably engageable with the female coupling part to guide the male coupling part into engagement. Also, the male coupling part and its guide structure define cooperating structural features which effect opening of the male coupling part in response to advancement relative to the guide structure.

Abstract: 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.

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.
