The invention concerns a container assembly provided with a top having a cylindrical neck (3) and a cap (10) including a base (11) to be fixed on said container top, the cap base being provided with an outer skirt (13) whereof the wall is adjacent to that (1) of the container. The outline representing the boundary between the cap outer skirt and that of the container is of any kind but is not centred on the neck axis. The container is provided with an inclined shoulder (2). The cap base is provided with a sealing skirt (14) penetrating inside the neck and several axial blades (12a, 12b) whereof the sections are preferably in the form of annular sectors. The neck is provided with a discontinuous annular rib (4), leaving one or several gaps (9a, 9b) matching the shapes of the corresponding axial blade sections. The neck and the axial blades are provided with matching snap-on means (6 and 16).
