FIELD: packaging means, particularly sealing devices for package closing.
SUBSTANCE: sealing device comprises pouring spout with radially projecting lower edges and threaded cap. Cap has diameter exceeding that of pouring spout. Deformable annular member is arranged between pouring spout and cap. Annular surface of annular member is inclined to ring surface. Inner ring edge passes into projection extending downwards. The projection may be put on pouring spout. Outer ring edge passes into projection directed upwards and adapted to be screwed into threaded cap. Annular member may be brought into two stable positions by elastic deformation thereof. In the first position annular surface rises from inner ring edge to outer ring edge. In the second position annular surface has reduced dimension.
EFFECT: increased cleanness of distributed liquid, provision of liquid package stacking.
