Abstract
A liquid cryogen dispenser 10 includes a consolidation structure 20 adjacent its outlet 14 for causing gas contained in the liquid to consolidate into bubbles of sufficient buoyancy to cause them to rise to the surface of the liquid rather than be drawn through the outlet 14 where they can disrupt the smooth flow of liquid cryogen therefrom.
