Abstract: A flask for medicinal preparations comprises a reservoir (1) with an orifice in the form of a neck (2), a rod (3) tightly fitted in the neck (2) and having one end extending outside the reservoir, and a sealing cap (10) placed above the neck of the reservoir. The rod (3) is made of a fibrous material (5) formed by longitudinal fibers and arranged in a casing (6) having a length less than that of the fibrous material at least for the outer part of the rod so as to form a brush (7). The fibrous material is embodied in the form of a bunch of longitudinal threads of natural or synthetic fibers.

Abstract: A flask for medicinal preparations comprises an elastic receptacle (1) with an orifice in the form of a neck (2), a porous plug-rod (3) arranged inside the receptacle and having one end extending out of the receptacle, and a sealing cap (7) placed above the neck of the receptacle. The elastic receptacle (1) is provided with a head piece (5) having an orifice of size not exceeding a cross-sectional area of the porous rod. A part of the porous rod disposed inside the receptacle has a cross-sectional area larger than the passage area of the receptacle neck orifice. The porous rod (3) is provided with axial notches (9) located on opposite sides of the rod. The porous rod (3) can be of circular or rectangular or polygonal cross-section. The flask is equipped additionally with a rigid body (8) embracing the elastic receptacle and mounted on the head piece (5) of the receptacle by means of a releasable connection. In addition, a spring clip (10) mounted on the outer surface of the sealing cap is provided.
