<p>A balloon stuffing system (25, 25', 25'', 25''') including a tubular member (26) open at one end (28) thereof and defining a chamber (31) capable of receiving the object (49) to be stuffed into a balloon (50); an ejector rod (29) passing through the opposite end (30) of the tubular member (26); a flexible, bellows-like, fluid impervious element (34) surrounding the ejector rod (29) and sealed at one end to the end (30) of the tubular member (26) and at its opposite end to the ejector rod (29); a fluid inlet aperture (56, 81, 85) formed in the tubular member (26) for permitting coupling of the interior of the tubular member (26) to any suitable source of pressurizing fluid; and, a balloon (50) having its inlet aperture (55) and constricted neck portion (58) mounted in surrounding sealed relation to the open end (28) of the tubular member (26) so that upon pressurization of the interior of the tubular member (26), the balloon (50) is inflated, and upon axial movement of the ejector rod (29) towards the open end (28) of the tubular member (26) the object (49) located within the tubular member (26) is ejected from the tubular member (26) and projected into the inflated balloon (50) which can then be removed from the tubular member (26) and its constricted neck portion (58) knotted or otherwise tied off to seal the balloon (50) in its inflated state with the object (49) being retained captive therein. The balloon stuffing system (25, 25', 25'', 25''') may include a balloon stretching mechanism (68) for facilitating placement of balloons (50) on the end (28) of the tubular member (26).</p> |
