Abstract
A straw for drinking liquids from an initially sealed container is provided with a pointed end for piercing an opening in the container. The straw is provided with a cross-sectional configuration which creates an unobstructed air passage into the container even when the opening formed by the straw is of no larger diameter than the end of the straw which is used to pierce the container. The straw may have an enlarged piercing head or recessed flutes extending longitudinally to assure creation and maintenance of the air passage.
