An example embodiment of an apparatus includes a fitting configured to couple to a pressurized supply of fluid. At least three branch assemblies extend from the fitting. Each branch assembly includes a tube coupled to the fitting at a first end, a balloon comprising a neck portion having a second end of the tube inserted therethrough, and a fastener removably coupling the balloon to the tube. The fastener is configured to permit fluid from the pressurized supply of fluid to pass through the tube and into the balloon and to automatically restrict the fluid from exiting the balloon through the neck portion upon decoupling the balloon and fastener from the tube.

An apparatus is for filling bags having a bag mouth extending in a direction of width with loose material. The apparatus includes grippers, suction cups, valves, and a pair of first carriages. The grippers are for gripping opposite edges of a bag, which are arranged opposite each other relative to a vertical axis of symmetry and are movable symmetrically towards and/or away from each other with respect to said vertical axis of symmetry in a direction parallel to the direction of width of the bag. The suction cups are for gripping side portions of the bag. The suction cups are movable symmetrically towards and/or away from each other along a direction perpendicular to the direction of width of the bag for opening and/or gripping the bag mouth of the bag. The valves can rotate from a closing position outside the bag into an opening position inside the bag mouth.

An apparatus for filling a plurality of containers with a fluid. The apparatus including a connector configured to removably couple the apparatus to a fluid source, a flow path providing fluid communication between the fluid source and a plurality of containers coupled to the apparatus, a sealing element disposed within each of the plurality of containers, the sealing element configured to couple the container to the apparatus and automatically seal the container when the container is decoupled from the apparatus, a retaining mechanism including an adhesive disposed on each of the plurality of containers to position the sealing element in a neck of each of the plurality of containers.

In a method embodiment, an example method includes attaching a balloon-filling apparatus to a water supply. The apparatus includes a fitting comprising an inlet and at least four outlets. The apparatus further includes at least four branch assemblies coupled to the fitting. Each branch assembly includes: a tube extending from the fitting at a respective one of the at least four outlets; a balloon comprising a neck disposed around an end of the tube; and a fastener attaching the neck of the balloon to the end of the tube and configured to automatically seal the balloon upon detachment of the balloon from the tube. The method further includes simultaneously providing water from the attached water supply to the balloons of the balloon-filling apparatus. The method also includes detaching one or more of the balloons of the balloon-filling apparatus using a force. The force is generated at least in part by one or more of: gravity of the balloons and the water contained therein; and an upward acceleration manually applied to the balloon-filling apparatus.
