The invention relates to closure devices of containers for low-viscosity liquids, in particular, to bottles protective caps preventing refilling thereof during storing and transporting.The bottle closure device comprises a body, an elastic element with projections on the base lower end face forming a cavity opened from atop and a sleeve for pouring out the liquid made as two bushings, inner of which has a dead upper end adapted to locate an elastic element in its lower part forming a hydroseal. The body for pouring out the liquid is adapted for axial displacement relative to the elastic element up to the stop in the bottom position of the dead end to the upper end of the inner projection of the elastic element.The technical result is aimed at a lesser number of parts and prevention refilling a bottle after opening thereof without increasing axial size of the device in the closed position. |
