Abstract
The invention relates to a closure assembly configured to be mounted on a neck of a container, which closure assembly includes a cap with a dispensing opening and a self-closing dispensing valve attached to the cap such that it is located adjacent the dispensing opening, and wherein the dispensing valve is a disc of foil material having a central valve area in which at least one self-closing slit is located and an annular peripheral attachment area extending around the central valve area, with which attachment area the dispensing valve is attached to the attachment area of the dispensing cap such that its central valve area aligns with the dispensing opening of the dispensing cap to close off that dispensing opening, and wherein an annular rib offsets the central valve area of the dispensing valve relative to a substantially flat attachment area of the cap.
