  • Patent number: 11827426
    Abstract: A valve carrier ring for carrying a self-closing dispensing valve is adapted to be assembled with a closure body of a container. The valve carrier ring includes an annular seat portion including a support surface for supporting a retaining portion of the valve and a circumferential wall located radially outwards of the support surface and extending coaxially with the support surface. The circumferential wall has a preformed radial protrusion adapted to extend over the retaining portion of the valve for providing a preliminary retention of the retaining portion in the seat portion. A snap bead is formed at a radial outer side of the valve carrier ring adapted to cooperate with a means of the closure body to provide a snap connection between the valve carrier ring and the closure body. The radial protrusion is constituted by a flexible inwardly inclined extremity of the circumferential wall.
