FIELD: equipment for liquid dispersion from bottles in small equal portions. SUBSTANCE: device includes vessel with small orifice formed in vessel neck and elastic bladder located inside vessel near bottom thereof. Bladder inner volume communicates with atmosphere. When vessel is located in non-upturned position air from bladder is displaced by liquid poured into vessel. When vessel is upturned liquid flows out of vessel through small orifice and atmospheric air enters bladder. After full bladder filling with air bladder volume stops to increase, which results in growth of pressure difference between vessel inside and outside and liquid flow is cut off. After vessel return into initial position liquid weight forces out air from bladder into atmosphere. Several elastic bladders may be inserted into vessel, wherein each bladder communicates with atmosphere through individual orifice. Liquid portion volume is changed by putting independent bladders out of action due to closing orifices in different combinations. Inner vessel space is separated from atmosphere by membrane located in lower vessel part. When vessel is located in upturned position liquid flows out and membrane is deflected into vessel. When vessel returns into initial position membrane flexes outwards under liquid weight. EFFECT: increased accuracy during liquid metering. 2 cl, 3 dwg |
