FIELD: technological processes. ^ SUBSTANCE: invention relates to the field of liquids packing and dispensation, such as pharmaceutical solutions, in particular eye drops. Reservoir comprises container with wall arranged with the possibility of manual deformation for dispensation of liquid (1) as wall (2) is pressed, and distribution head (3). Hollow body (4) of distribution head (3) is equipped with nozzle (5) for dispensation of liquid (1). Hydrophobic microporous plug (8) of distribution head is arranged behind reservoir. Reservoir is equipped with a detachable cap (6) for tight closure of nozzle (5). Plug (8) in combination with cap (6) prevents spontaneous outflow of liquid (1) towards nozzle (5) from volume (15) of container. Liquid (1) from volume (15) of container freely flows via plug (8), when nozzle (5) is opened for distribution of required portion of liquid (1) by means of pressing against wall (2) of reservoir. Wall of reservoir is arranged with the possibility of reversible deformation as a result of air suction inside reservoir (2) with further spontaneous return of reservoir to initial shape after liquid (1) discharge. Cap (6) is arranged with the possibility of air impermeable closure of nozzle. When cap (6) is open, plug (8) lets sucked air into specified volume (15) for storage as a result of elastic return of container wall (2) to initial shape. Body (4) of distribution head is installed inside neck (10) as fixed, and upstream nozzle (5) there is an antibacterial filtering membrane (7) installed. Membrane (7) comprises hydrophilic part for passage of liquid under action of excessive pressure pulled in container at its wall, and hydrophobic part for passage of air under action of underpressure that occurs when wall is no longer pressed. ^ EFFECT: simplified design of device for storage of liquid. ^ 14 cl, 3 dwg |
