The manually-operated balloon stuffing device has a minimum number of parts and is inexpensive to manufacture. The device includes a manual pump consist- ing of inner and outer cylindrical tubes, and a check valve in each tube that permits the passage of air in only a single direction within its respective tube. In a first embodiment, a balloon stuffing item is placed in an end of the inner tube, and the open balloon end is stretched over that tube end. The outer tube is then reciprocated along the longitudinal axis of the inner tube to pump up the balloon. The outer tube is then removed and a push rod pushes the sliding check valve, which in turn pushes the stuffing item into the inflated balloon. In an alternate embodiment, a large hollow adapter tube is placed on the end of the inner tube, and the open end of the balloon is stretched over the open end of the adapter tube. After the balloon is inflated, a push rod pushes the sliding check valve, which in turn pushes an extension rod, the latter moving the stuffing item into the balloon. In yet a third embodiment, the need for a push rod and a slidable check valve is elimi- nated by using a connector between the tube in which the item is placed on the upper end of the inner tube. Once the balloon is inflated as before, the inner tube is pushed through the third hollow tube, thereby pushing the item into the balloon.
