A dispensing structure is provided for a container that has an opening to the container interior. The dispensing structure includes a body for extending around the container opening and defining and access passage for access through the container opening. The body includes a chamber for receiving an additive product for adding to the container. The chamber has an initially closed upper end and has a bottom end defining a bottom end opening. A movable, bottom end closure is provided for releasably closing the chamber bottom end opening. A deformable cover is mounted to the body to accommodate deformation from an undeformed condition at which the bottom end closure closes the chamber bottom end opening to a deformed condition at which the bottom end closure is engaged and moved by the cover to a position that opens the chamber bottom end opening.
