A flow control device 10 for dispensing liquid from a liquid-tightly sealable container into a second container to a predetermined level. The device comprises a liquid flow channel 14 having an inlet end 34 and an outlet end 36; a fluid flow channel 16 independent of the liquid flow channel 14 and having an inlet end 38 and an outlet end 40; and a flow control element 18 by which flow is substantially prevented from exiting the outlet end of the liquid flow channel 14. The flow control element 18 is a substantially stationary slotted element 18 having a plurality of elongate slots (42, Fig.1b) forming liquid flow apertures (44, fig.1b) therethrough. The slots 42 have longitudinal extents which extend across a flow path of the liquid flow channel 14, and the elongate slots 42 are dimensioned to substantially halt liquid flow along the channel 14 when it is tilted to a flow condition and the fluid flow channel 16 becomes at least in part filled with liquid. Flow in the channel 14 remains halted or substantially halted until the channel 14 is righted to an at rest condition. |
