Abstract

A valve and retainer assembly particularly useful for latex balloons includes a valve body and a band valve. The valve body has a radial shoulder where the neck and mouth of a latex balloon may be received to affix the balloon to the valve body. A hollow stem extends from a first open end to a second closed end, and a one-way valve allows gas to be introduced through a fill aperture in the stem and into the balloon affixed to the retainer portion. The stem includes a bell mouth at the open end to facilitate the creation of a hermetic seal with valves of gas storage tanks and to improve the efficiency of filling said balloons. The one-way valve includes a band valve positioned around the stem and covering the fill aperture. Fingers may be provided on a top surface of the radial shoulder to retain the band valve against movement under high pressure.
