Dispensing container

Claim 1

A normally upright liquid container for storing and dispensing a liquid and having a longitudinal axis which extends substantially vertically when said container is upright, comprising: top, bottom and side walls impervious to the passage of fluids and interconnected to one another in fluid-tight relationship to define such liquid storage container; means defining a discharge opening through said walls at the top end of said container for discharging liquid therefrom; a baffle extending transversely of said axis and disposed internally of said container below said discharge opening and above the level to which said container normally is filled with liquid, said baffle joining said walls in fluid-tight relationship and cooperating therewidth to divide said container into a top discharge chamber above said baffle and a storage chamber including the remainder of said container therebelow; an open passageway through said baffle from said storage chamber to said discharge chamber for free flow of liquid from said storage chamber to said discharge chamber when said container is appropriately tilted, said passageway limited to an area proximate to one side of said container; said baffle and said walls being impervious to and precluding the passage of fluid between said chambers other than through said passageway; each of said chambers being open and unobstructed to free flow of liquid in said storage to and through said passageway and to said discharge opening when said container is so tilted; wherein said baffle is in a position to leave an unfilled volume within said storage chamber, below said baffle and above said normal filling level, which volume is approximately equal to the volume defined by said one side of said container and a liquid surface which is level with the lower edge of said passageway when said axis is horizontal and said one side is upwardly disposed; whereby gravity-flow of liquid from said storage chamber to said discharge opening is prevented until said container is tilted to or beyond a substantially horizontal position of said axis and is permitted upon further tilting of said container toward an inverted position.
