FIELD: packing means, particularly pliable tubular containers adapted to be permanently deformed to expel contents. ^ SUBSTANCE: metering device is adapted to distribute two separately stored materials, which are combined during metering to produce composite product. Metering device has vessel including at least two inner storing compartments and lid. Each compartment has separate outlet orifice. Flexible valve is connected to each outlet orifice. Each valve has initially closed metering orifice which opens in response to pressure difference. Device has upper part located downstream of the valve and fixing plate. Upper portion may be moved between closed position in which metered flow is restricted downstream of the valves and opened position, which provides product flow out of the device. Flexible valves are made on unit formed of elastomeric material. ^ EFFECT: increased reliability of material storage, transportation and distribution in necessary amounts and with demanded dispersity. ^ 6 cl, 20 dwg |
