a bottle having a closed bottom end and an open top end, the bottle defining an interior space;

a cap selectively connectable to the bottle and configured to close the open top end of the bottle;

a nozzle carried by the cap, the nozzle movable between an open position and a closed position, wherein liquid contents of the bottle can be dispensed through an outlet passage of the nozzle when the nozzle is in the open position, wherein an outlet opening of the outlet passage extends through an upper end surface of the nozzle;

a vent configured to permit a vent flow of vent air from an atmosphere outside of the bottle assembly to the interior space of the bottle through an elongate vent passage at least partially defined by a tubular vent body that extends from an interior surface of the cap in a direction towards the bottom end of the bottle with the cap connected to the bottle;

a dividing wall within the elongate vent passage that separates the interior space of the bottle from the atmosphere, the dividing wall comprising a plurality of vent openings extending therethrough;

a check valve that is configured to permit the vent flow of vent air and inhibit or prevent a flow of air or the liquid contents through the vent in a direction from the interior space of the bottle to the atmosphere, the check valve comprising a valve body having a stem portion and a flattened head portion connected to the stem portion, the stem portion passes through an opening in the cap to secure the valve body to the cap, the flattened head portion selectively covers the plurality of vent openings on the interior surface side of the cap, and;

a vent conduit that is friction fit onto the tubular vent body, the vent conduit having a terminal end located within the interior space of the bottle with the cap connected to the bottle, wherein the terminal end is closer to the bottom end of the bottle than the top end.
