ABSTRACT:
A packaging unit has a container closed by a safety plug which has a maximum diameter equal to the outer diameter of the container opening and a smooth exterior to avoid any gripping surface. A cylindrical lip adjacent to the peripheral edge of the plug cooperates with the inner surface of the container opening to seal the opening. A slide is movable along a radial direction of the plug to extend beyond the edge of the container opening to provide a gripping surface for removing the plug. Safety detents may be provided which must be manipulated to permit movement of the slide.
