The multi-piece fitment (430 and 440) includes a base (430) for mounting to the container and a valve carrier (440) for mounting to the base (430). A flexible, self-sealing slit-type valve (180) is mounted within the carrier (440). In another embodiment, a fitment (20) is mounted in the opening of a flexible, collapsible container, and the flexible valve is mounted in the fitment. In yet another embodiment, a package includes a container (322) defining an opening (340) and a fitment (344) is sealingly mounted to a corner wall (334) at the opening (340). A valve (180) is disposed within the fitment (344). A removable and disposable cover (360) extends from the container (322) over the fitment (344) to define a hermetically sealed volume around the fitment (344). The cover (360) may be pulled away from the container (322) to expose the fitment (344).</p> |
