Abstract
A safety drinking straw includes a beverage delivery tube having a tube first end for insertion into a quantity of beverage and a tube second end for placement between user lips; and a debris blocking structure substantially at the tube first end permitting a free flow of the beverage through the delivery tube while preventing entry of debris of a selected minimum target size into the delivery tube; so that the debris blocking structure prevents debris from entering the delivery tube and thus prevents debris from lodging and becoming an obstruction within the delivery tube. The debris blocking structure preferably includes at least one cord extending across the interior of the delivery tube substantially at the tube first end, and alternatively includes at least one tube partition or at least two tubular barrels fitted longitudinally and in tandem inside and secured within the delivery tube.
