ABSTRACT:
A closure (e.g. cover, cap, lid, etc.) having anti-evaporation and spill-resistant features for use on a multi-serving capacity (e.g. 1, 11/2, 2 gallons) container for hot beverages (e.g. coffee, tea, soup) and near-boiling water and incorporating a filling passageway formation through which hot beverages and water may be introduced to fill a container while the closure is in place thereon. A light-weight floating ball normally seats on the upper side of a filling orifice and minimizes evaporation. A heavy-weight (e.g. steel) ball seats against the opposite side of the orifice and prevents the contents from gushing out in the event the container is overturned.
