FIELD: transportation, distribution of liquids. ^ SUBSTANCE: device for aseptic storage of liquid and distribution of multiple portions of stored liquid comprises structure of one way valve and reservoir with variable volume. One way valve comprises body that includes at least one channel for liquid and valve cover made of elastic material. Cover base is installed onto valve body and is tightly fixed relative to it. Besides valve body contains valve part passing in axial direction with specified thickness in radial direction and forming valve channel, which is normally closed and passing in axial direction. Valve part may move in radial direction between position closed in normal condition and open position, in which at least one segment of valve part is distanced in radial direction from closed position, which results in liquid interrelation of valve channel and at least one channel for liquid, which makes it possible for liquid to travel from at least one channel for liquid through channel of valve and flexible container, which forms tightly closed reservoir with variable volume for storage of multiple liquid portions in aseptic conditions, which is in liquid interrelation with structure of one way valve. Relative rigid body includes flexible container and pump arranged between reservoir and one way valve, which pumps separate portions of liquid from reservoir through at least one channel for liquid and through channel of valve in order to extract portions of liquid. When pumping separate portions of liquid through one way valve, one way valve and reservoir maintain liquid that remains in reservoir in aseptic conditions and tightly closed relative to effet of environment. Method is provided for aseptic storage of liquid and distribution of multiple portions of stored liquid, as well as structure of flexible pocket and valve for aseptic storage of substance, distribution of multiple portions of stored substance and maintenance of substance that remains in pocket in aseptic conditions, as closed against effect of environment. ^ EFFECT: development of device for aseptic storage of liquid and distribution of multiple portions of stored liquid, using which eliminates risk of ingress of bacteria or other undesirable substances that contaminate the product. ^ 21 cl, 18 dwg |
