Multi-chambered bottle with metering stage, pour spout and cap

摘要

A multi-chambered bottle includes first and second chambers, a metering stage, a pour spout and a cap. The metering stage includes first and second metering stage sections connectable to respective mouths of the first and second chambers. Each metering stage section comprises a nozzle having a liquid inlet orifice and a liquid outlet orifice, and a vent tube having an air inlet orifice and an air outlet orifice at opposite ends of the vent tube, the air inlet orifice to be disposed outside of the respective chamber and the air outlet orifice to be disposed inside of the respective chamber, the vent tube disposed relative to the nozzle such that a line crossing a center of the air inlet orifice and a center of the liquid outlet orifice forms an acute angle with a normal axis of the bottle.

1. A multi-chambered bottle comprising:
first and second chambers; a metering stage including:
first and second metering stage sections connected to respective mouths of the first and second chambers and separated by a normal-center plane of the bottle, each metering stage section corresponding to a respective one of the first and second chambers, each metering stage section comprising:
a nozzle that tapers to a liquid outlet orifice as it extends from a liquid inlet orifice along a longitudinal axis of the bottle, and a rim portion that surrounds the liquid outlet orifice, anda vent tube having an air inlet orifice and an air outlet orifice at opposite ends of the vent tube, the air inlet orifice disposed outside of the respective chamber and the air outlet orifice disposed inside of the respective chamber, the vent tube disposed relative to the nozzle such that a line crossing a center of the air inlet orifice and a center of the liquid outlet orifice forms an acute angle with a line crossing the center of the liquid outlet orifice and parallel to a normal axis of the bottle; and a pour spout releasably attachable relative to the metering stage and including:
first and second pouring channels, each pouring channel corresponding to a respective one of the nozzles of the first and second metering stage sections, each pouring channel including:
a liquid inlet that connects to the respective nozzle, anda liquid outlet that has an opening that narrows as the opening extends away from the normal-center plane of the bottle along a latitudinal axis of the bottle, a stepped rim that surrounds at least a portion of the opening and a divider disposed adjacent a portion of the opening nearest to the normal-center plane of the bottle,wherein at least a portion of a wall of the pouring channel slopes in a direction towards the normal-center plane of the bottle as it extends from the liquid inlet to the liquid outlet.
