BEVERAGE FROTHING

摘要

A pressurised beverage container has device for jetting gas into the beverage upon opening. The device has a first orifice (81) and a second orifice (84) which communicates with the internal chamber of the device via a standpipe (92) which opens into the internal chamber at a position below the surface level of a liquid (86) held within the device. When the device fires upon opening of the container, the liquid (86) is forced up the standpipe (92) to contact the second orifice (84) so that pressurised gas from within the device is jetted preferentially through the first orifice (81) into the beverage.
