ABSTRACT:
A container with flexible walls has bonded to it a closure which is scored, perforated, narrowed or otherwise weakened in selected patterns such that the closure will substantially retain the liquid in the container while the container is rotated to a pouring position. However, the closure will irreversibly fail and thereby release the liquid when the user squeezes the bottle while in the pouring position.
