ABSTRACT:
A side evacuating balloon inflater includes a lower shell, an upper shell, a collar insert, and a check valve. The lower shell is sealed to the upper shell with a gasket. A collar insert is slid into an inner diameter of a bore that is disposed on the top of the upper shell. A plurality of nubs are spaced around the collar insert. A balloon is stretched over the nubs and is retained thereby. A tapered boss surrounds the check valve which is disposed in the shell structure. The tapered boss facilitates the sealing of different size vacuum tubes to the shell structure. A household vacuum cleaner or a shop vacuum is used to pull a vacuum on the shell structure. The vacuum causes the balloon to stretch to the inside wall of the shell structure. The vacuum tube is removed and the check valve retains the vacuum inside the shell structure. Novelty items may be inserted into the mouth of the balloon; the balloon is then be sealed with a clip.
