Abstract
An embodiment of a cap for a bottle may comprise a body and nozzle. The body may include an annular wall, an aperture configured to receive a nozzle, and a plug rigidly attached within the aperture. The nozzle may be movable between a retracted position in which fluid cannot pass between plug and nozzle, and an extended position in which fluid can pass between plug and nozzle. The nozzle may include an inner wall and an outer wall. The outer wall may have at least one longitudinal recess. The longitudinal recess may allow selective passage of air. The longitudinal recess may allow air to flow through the recess and into the bottle when the nozzle is in the extended position, and is contained within the aperture and is thus configured to prevent air from flowing through the recess and into the bottle when the nozzle is in the retracted position.
