Abstract
A self-draining container neck and closure comprising a container neck having an upper sidewall portion and a lower sidewall portion, the upper sidewall portion being inset from the lower sidewall portion. The container neck also includes a tamper indicating bead having at least one draining notch therein. The instant invention also includes a closure having a plurality of drainage slots disposed in a spaced configuration. The closure is threadably connected to the container neck, the closure and container threads rotatably engage and provide a drainage path there between.
