Abstract
Carbonated liquid under pressure is conducted to a point which is at a pressure close to atmospheric pressure without excessive loss of carbonation over a helical flow path formed from a tubular member having an inner circumference and a helical insert having a threaded portion disposed within the tubular member with the threaded portion and the inner circumference together defining the helical flow path. The helical insert has an upstream end formed with a pointed nose adjacent one end of the threaded portion and a downstream end formed as a flat tail adjacent the other end of the threaded portion. The helical flow path has a predetermined length and essentially constant cross section which tends to reduce the pressure of the solution without excessive loss of carbonation.
