Abstract: An improved method for inserting valves between the front and back panels of inflatable bodies, such as novelty balloons or air-inflated dunnage bags, is disclosed. The method includes the steps of conveying an upper web through an upper roller assembly and conveying a lower web through a lower roller assembly positioned adjacent to and below, and pivotal relative to, the upper roller assembly. The valve is then inserted between the top and bottom webs as they pass through the roller assemblies and then the roller assemblies are pivotally clamped together to bring the top and bottom webs together and frictionally engage the valve between the webs. The webs are then conveyed, with the valve clamped therebetween, to a downstream die station without any attachment of the valve to either of the webs prior to reaching the die station. At the die station, the perimeter of the inflatable body shape is heat sealed into the webs which simultaneously heat seals the valve to both of the webs.

Abstract: A packaged balloon and greeting card are disclosed comprising a balloon having an uninflated body, a filler neck extending from the body, and a first image displayed on the body; a greeting card having a face displaying a second image matching the first image; a tether line having a first end attached to the filler neck and a second end attached to the greeting card; and a packaging envelope receiving the uninflated balloon body, the greeting card, and at least a portion of the tether line. A third image, matching the first and second image, can be displayed on the envelope. The packaging envelope can also include an opening through which the balloon filler neck extends outside the envelope for communication to a source of inflating gas to permit in-situ inflation of the balloon body in the envelope. The envelope can also be constructed so as to be burst by inflation of the uninflated balloon body while it resides in the envelope to facilitate unpackaging of the balloon for use.

Abstract: Balloon stem connector for securing a balloon by its neck to the end of a stem-like object includes a wire formed slot at the end of the stem for receiving the balloon neck. A capture element having a tubular body portion is fitted in sleeve-like fashion to slide along the stem from a position where the slot is fully exposed to a captive position where it envelops a substantial portion of the loop. The capture element also has balloon positioning body portions outwardly flaring from the tubular body.
