Abstract
A device to inflate a balloon and maintain it in an inflated state while providing access to the expanded balloon orifice for purpose of inserting objects. The device has a transparent, cylindrical, balloon chamber covered by a vertically movable lid having a balloon orifice expanding mechanism consisting of multiple, cam actuated, retracting fingers. Lid support columns also function as air supply ducts and have stops to hold the lid at convenient elevations for insertion of deflated balloons and removal of inflated balloons containing objects. A preferred embodiment applies positive pressure to inflate the balloon, although vacuum applied exterior to the balloon is also workable.
