FIELD: devices for discharging contents from packages, particularly from compressible containers. ^ SUBSTANCE: system comprises elastic-plastic molded valve assembly formed as a single unit to be sealed to container above container orifice. Valve system includes impermeable diaphragm, several plastic-plastic slot-like valves integrally formed with diaphragm. Each valve has concave central wall with normally closed distribution orifice, which opens when internal container pressure exceeds pressure of valve outside by a given value. These valves are adapted to distribute several parallel, convergent or divergent flows. ^ EFFECT: increased measuring accuracy, production simplicity, possibility to use system for spraying separate flows. ^ 18 cl, 54 dwg
