Abstract
A tight screw cap having a cylindrical outside skirt threaded on the inside surrounding a pan bottom having a circular bottom wall surrounded by a cylindrical lateral wall connecting it to the upper edge of the outside skirt of the cap. The outside diameter of this lateral cylindrical wall corresponds to the inside diameter of the threaded upper end of the neck of the container, the length of the cylindrical wall being less than that of the cylindrical skirt. The bottom wall of the pan bottom is connected to its lateral cylindrical wall by a part in the shape of a crown of bitruncated section delimiting, at the periphery of the bottom wall, an annular groove of approximately annular section projecting, in relation to the bottom wall, from the same side as the free end of the outside skirt.
