FIELD: physics.
SUBSTANCE: container has a side wall (2) whose ends (3, 4) are equipped with closing elements (5, 6), at least one of which is connected to close an opening. The outer profile (6c) of the inserted closing element (6) and the inner profile (4a) of the corresponding end (4) of the side wall (2) have complementary general shapes on at least part of their corresponding height such that the inserted closing element (6) enters with at least part of its height into the inner space bounded by the end (4) of the side wall (2) and rests on said end (4) by protrusions (11) entering sockets (10) of the corresponding shape. Inclined seating planes form an angle of 20-40° with the axis of the container.
EFFECT: invention enables to withstand considerable expansive forces of products contained therein.
