Abstract
An improved dispensing package for liquids is described comprising a combination pouring spout fitment, a closure that functions as a measuring cup when removed and inverted, and a bottle. The improved liquid seal between the closure and the fitment is made possible through mismatched bevels on the closure and fitment respectively wherein the sharper angled bevel on one of the parts buries into the wider angled bevel of the other part. The applied torque is prevented from loosening prematurely through a thread configuration form that allows the closure to seat securely into the spout fitment with the closure threads pushing back up against the bottom surfaces of the fitment threads in a “locked” arrangement. The correct alignment of the fitment on the bottle is made possible through the coordination of a thread stop on the fitment and corresponding locking lug on the neck of the bottle. Lastly, an indicia means is used on the outside of the fitment skirt to verify that the spout fitment and closure subassembly has been correctly orientated on the bottle even through the direction of the spout is obscured when the closure is in place.
