A package comprising

• a container formed to include an interior product-storage region and including a body and a filler neck coupled to the body, the filler neck being formed to include a mouth arranged to open into the interior product-storage region, and
• a dosing dispenser configured to mount to the filler neck of the container to control release of product from the interior product-storage region to a syringe,
• wherein the dosing dispenser includes a closure coupled removably to the filler neck and an anti-suction valve fixed to the filler neck, the closure including an inner cap configured to mount to the filler neck and an outer cap coupled to the inner cap, the outer cap being rotatable relative to the inner cap in a child-resistant locked position, the closure being configured to change from the locked position to an unlocked position in response to an unlocking force applied on the outer cap to cause the inner cap to rotate with the outer cap to remove the closure from the filler neck, and
• wherein the anti-suction valve is mounted to the filler neck to cover the mouth and includes a lower surface located below the mouth between the body and the mouth, an upper surface located at or above the mouth, and a fluid passageway that extends from the upper surface to the lower surface to open into the interior product-storage region, the anti-suction valve formed to include a plurality of airflow recesses that are arranged to extend between the lower surface and the upper surface and are configured to minimize formation of a complete seal between a child's mouth and the upper surface so that sufficient suction to remove fluid through the fluid passageway is blocked.
