Improvements in the construction of hermetic closures for containers characterized in that the elastic ring that is interposed between the edge of the lid and that of the container for effecting such closure supports on the last of said edges by means of an annular piece that fits into it and presents at the same time an upward concave rim that rests on the one of the container, the elastic ring being included between the concavities of the edge of that supplementary piece and that of the lid.
