The invention relates to a screw top comprising
essentially two elements formed by a skirt and a sealing ring connected
together in a number of places by means of small cross-elements
which can be broken when unscrewing the top, characterised in that
of said two elements, either the skirt (2) or the sealing ring (3) compri-
ses prolongations (8-10) which extend sufficiently far towards and
beyond the opposite element so as to prevent any deformation of
the sealing ring (3) in the radial direction of the top.
