Abstract: A balloon filling device is provided. The balloon filling device includes a hose connector extending outwards from a body of the balloon filling device, a hose barb extending outwards from the body along a predominant axis, the hose barb being displaced on the body from the hose connector, a valve within the body having an opened state where the valve forms a conduit between the hose connector and the hose barb and a closed state where the conduit is blocked and a receptacle disposed in the body adjacent the hose barb that receives a balloon tying device.

Abstract: An apparatus for filling a balloon with a fluid and tying a knot in the neck of the balloon, having a filling device body engaging a source of fluid under pressure. A balloon barb extends outwards from the body, and a fluid passageway in the body communicates with a control to allow the passage of fluid from the source to the balloon barb. A tying device extends from the body substantially parallel to the balloon barb, the tying device being detachable from and reattachable to a receptacle in the body of the filling device. A keyway is located either the tying device or an inner surface of the receptacle, and a key is located in the other of the tying device or the receptacle. The key corresponds in dimensions to fit in the keyway, where the key removably fits into the keyway when the tying device is inserted in the receptacle of the body of the filling device.

Abstract: A balloon tying device is provided. The balloon tying device includes a cylindrical shaft, a slot extending across a marginal end of the cylindrical shaft with a depth of the slot extending along a longitudinal axis of the shaft by a distance at least equal to a diameter of the shaft, a bevel located on a first side of the cylindrical shaft on opposing sides of the slot and extending from a root of the slot towards the marginal end and the shaft having a tapered end, but only on a side of the shaft opposite the bevel, with the taper starting near the root of the slot and ending with a maximum taper on the marginal end and where the taper divided by the slot.
