CORKING CAP FROM POLYMER MATERIAL Russian patent published in 2013 - IPC B65D47/06 B65D47/20 B65D35/38 

FIELD: transport, package.

SUBSTANCE: invention concerns capsule made of polymeric material which capsule is intended to be fixed on the neck of elastic bottle for release of thixotropic fluids. The capsule (1) made of polymeric material includes lower part (2) and cover (6) and is provided with ring-shaped securing bead (10). Disk (11) with resting surface (12) is fixed in it with form and/or force closure. The disk (11) has central rise which diameter is less in its diameter than rise (7) in covering surface (4) of lower part (2) and has central recession (15) around which there are axial through holes (13) which falls into space (17) between upper side of disk (11) and lower side of covering surface (4') of rise. Thixotropic fluid contained in elastic reservoir enters the space (17) through holes (13), whereupon the fluid changes direction from axial to radial, and after the second change of direction from radial to axial flows out through outlet (5). In this process, flow acceleration takes place due to constriction (21) between two changes of direction.

EFFECT: good flow characteristics of thixotropic fluid.
