1. A dispensing structure for a container that has an opening to the container interior, said dispensing structure being in the form of a dispensing closure comprising:

  • a body for being mounted to said container around said container opening and defining an access aperture for access to said container opening;

    a membrane sealing said access aperture closed;

    a cover disposed over said membrane and sealingly engaged with said body to accommodate axial sliding movement from an outer position to an inwardly displaced position, said cover defining a dispensing orifice and defining an edge for severing at least part of said membrane as said cover is non-rotatably moved from said outer position to said inwardly displaced position, said cover and said body together defining a chamber over said membrane;

    an additive product in said chamber for adding to said container after at least part of said membrane is severed;

    a removable tamper-evident band initially secured to said cover to prevent movement of said cover toward said inwardly displaced position until said band is torn at least partly away from said cover; and

    a lid and a hinge connecting said lid to said cover for accommodating movement of said lid between (1) a closed position over said cover dispensing orifice to close said orifice, and (2) an open position away from said lid closed position.
