Pediatric dosing dispenser

A closure comprising

• an inner cap including an inner top wall formed to include a first opening, an inner side wall arranged to extend downwardly from the inner top wall and circumferentially around a central axis, and an inner plug unit coupled to an outer surface of the inner top wall and arranged to extend upwardly away from the inner top wall,
• an outer cap including an outer top wall formed to include a second opening, an outer side wall arranged to extend downwardly from the outer top wall and that extends circumferentially about the central axis, and an outer plug unit coupled to a bottom surface of the outer top wall and arranged to extend downwardly away from the top wall, the outer cap being mounted to the inner cap for rotation relative to the inner cap about the central axis from a closed position in which the outer top wall and the inner top wall are spaced apart from one another by a first distance and the inner plug unit and the outer plug unit cooperate to block fluid flow through the first and second openings, to an opened position, in which the outer top wall is spaced apart from the inner top wall by a second distance greater than the first distance and first and second openings are opened to allow fluid to flow therethrough, the outer cap being adapted to receive a syringe to remove a fluid from the chamber when the outer cap is in the opened position, and
• a child-resistant closure-release mechanism configured to block rotation of the outer cap relative to the inner cap from the closed position to the opened position,
• wherein the outer plug unit includes an outer seal ring that extends circumferentially around the central axis to define a chamber radially inward of the outer seal ring and a first plug that extends downwardly from the outer top wall into the chamber.

A closure comprising

• an inner cap including an inner top wall formed to include a first opening and an inner side wall arranged to extend downwardly from the inner top wall and circumferentially around a central axis,
• an outer cap including an outer top wall formed to include a second opening, an outer side wall arranged to extend downwardly from the outer top wall and that extends circumferentially about the central axis, the outer cap being mounted to the inner cap for rotation relative to the inner cap about the central axis from a closed position to an opened position, and
• an anti-suction feature coupled to an upper surface of the outer top wall and arranged circumferentially around the second opening and configured to block formation of a seal between a child's mouth and an upper surface of the outer top wall so that, if the child attempts to apply a suction force on the outer top wall over the second opening, air is drawn into the child's mouth without any fluid being removed through the second opening,
• wherein the anti-suction feature includes an anti-suction ring coupled to the upper surface of outer top wall and arranged to surround a perimeter edge of the first opening and a plurality of anti-suction ribs arranged to extend outwardly away from the anti-suction ring toward an outer perimeter of the outer top wall.
