Abstract
A valved dispensing closure is adapted to be mounted on a resiliently deformable bottle. The valved closure has a self-sealing dispensing valve mounted internally of the base of the closure by a securement in the form of an internally mounted retaining ring or inner deformable plug. A protective cover is adapted to extend over the side and top of the base to protect the valve from inadvertent activation. A tamper evident part is at the bottom of the base to visually indicate when the closure is removed after having been applied on the container after it is filled with product to be dispensed.
