ABSTRACT:
Inflating apparatus and method disclosed has a base preferably mounted on the side of a gas-filled tank and located approximately at or below waist level. A balloon is mounted on a mounting sleeve on the base. The balloon is mounted so that an end section of the neck portion is expanded and everted back over a top lip of the mounting sleeve to form an air-tight connection with the mounting sleeve and the neck portion extends down through the sleeve. If a coating material is desired on the outside of the balloon the coating material is initially placed inside the balloon, the balloon is mounted on the top of the sleeve and turned inside out by being passed down through the mounting sleeve before inflation. A fill plug is pressed down against an end section of the balloon on top of the mounting sleeve to form an air-tight seal and gas under pressure is selectively passed into the balloon. A size gauge indicates when the balloon is a selected size. A closure in the form of a twist ring twists the neck of the inflated balloon. A knot tying device is provided to tie a knot in the neck of the balloon to close off the fill opening and in the alternative a tie line may be used to tie the neck portion of the balloon closed.
