Abstract: The present invention is directed to apparatus and methods for inserting objects into balloons. The apparatus preferably includes a housing having a balloon chamber and a vacuum pump chamber therein. The balloon chamber is large enough to accommodate an inflated balloon and has a lid through which the inflated balloon can pass. The vacuum pump chamber houses a vacuum pump which is in gaseous communication with the balloon chamber in order to create a vacuum therein. The lid includes an adjustable mechanism for first expanding and then maintaining a balloon orifice in an expanded condition to enable access to the interior of the balloon in a position in which the balloon extends downwardly from the lid to a position inside the balloon chamber. The vacuum pump may then be actuated to cause the balloon to inflate within the balloon chamber so that the desired object may be inserted through an access opening in the lid to the inside of the balloon.
