Abstract (en)

[origin: WO2020186280A1] The invention relates to a melt transporting device (1) comprising a melt container (3) in which a melt receiving chamber (4) is formed and comprising a spout (5), said spout (5) having a spout opening (6). A gas valve (7) is provided which is fluidically connected to the melt receiving chamber (4) and which is designed to regulate the introduction of gas into the melt receiving chamber (4). Furthermore, a) the spout (5) is equipped with a siphon (13) which has a reservoir (14) that is arranged between the melt receiving chamber (4) and the spout opening (6), and the reservoir (14) has an overflow level (17), wherein a siphon wall (15) is provided which has a siphon wall lower edge (41), and the siphon wall (15) protrudes into the reservoir (14) such that the siphon wall lower edge (41) is arranged on a lower level than the overflow level (17) of the reservoir (14), and/or b) the spout (5) is equipped with a filter (24) which has a mesh width (25) between 0.05 mm and 10 mm.
