Abstract
A dispensing structure is provided for a container which has an opening to the container interior. The structure includes a body for extending around the container opening and a membrane for occluding the container opening. A cover is disposed over the membrane and is sealingly engaged with the body to accommodate axial sliding movement from an outer position to an inwardly displaced position. The cover defines a dispensing orifice and defines an edge for severing at least part of the membrane as the cover is moved from the outer position to the inwardly displaced position. An additive material may be initially stored in the dispensing structure above the membrane and can be combined with the product in the container after the membrane has been severed. A self-sealing, pressure-openable, slit-type valve may be mounted in the cover at the dispensing orifice to control flow through the orifice.
