摘要： A valve closure for a dispenser comprises a rigid body portion and a flexible diaphragm that engages the body portion when the valve closure is mounted in the dispenser. The valve closure may include a combination central boss/pin and dispensing orifice that, through a self-closing and self-sealing action, cuts off material flow following dispensation. Such configuration of a central boss/pin may also tend to prevent or at least reduce orifice re-healing by holding open the orifice during periods of non-use when the orifice is cut-off to material flow. For example, the central boss/pin may include an undercut region with which an annular lip of the orifice may engage to seal the orifice. The valve closure may further include a secondary channel, in addition but separate to a primary fluid flow channel, which may be used to provide external air venting that is completely or substantially de-coupled from fluid dispensation.
