Abstract
Apparatus for inflating balloons to enable insertion thereinto of objects includes a loading ring insertable into the orifice or mouth of the balloon for stretching the orifice to allow insertion therethrough of an object into the interior of the balloon when inflated, and a balloon inflating housing for accommodating an inflated balloon. The housing includes upper and lower hemispherical shells which may be sealingly fitted together to form a complete spherical shell and to allow inflation of the balloon therewithin, and then separated to allow removal of the inflated balloon. The housing further includes an annular opening located in the upper hemispherical shell through which a balloon orifice may extend, a support ring disposed in the annular opening for receiving the loading ring so that a balloon in whose orifice the loading ring is inserted extends downwardly into the housing, and an opening in the lower hemispherical shell through which air may be evacuated from the housing to cause inflation of the balloon. The lower hemispherical shell may be coupled to a pump so that when the pump is operated, air from the interior of the housing is removed to thereby inflate a balloon disposed within the housing.
