Embodiments of this invention provide an arrangement easier for the consumer to use as it is self “seating” and requires very little if any pressure to affix as gravity does most of the work. The internally fitted lid of one embodiment seals a larger area of the beverage container opening by relying on the matching the draft angle of wall of the internally fitted lid with the draft angle of the beverage container.
