Abstract: A no spill bottle arrangement including a bottle and a removable cap. A valve assembly is disposed on the inside of the cap to prevent liquid from accidentally flowing from the bottle. The cap has a housing having an inlet opening for liquid to enter the housing from the interior of the bottle and an outlet opening for liquid in the housing to flow into the spout. The valve assembly includes a valve seat in the housing and a valve cooperating with the seat for preventing flow of liquid from the inlet opening to the outlet opening when the valve engages the seat, said valve being biased to a closed position engaging the seat but disengaging the seat to move to an opened position in response to a drop in pressure caused by sucking action on the spout.
