Abstract:
1. A method of drinking a beverage, comprising the steps of: providing a vessel having a vessel opening; providing a quantity of beverage within the vessel containing debris; providing a safety drinking straw comprising a beverage delivery tube having a substantially circular tube cross-section and a tube first end and a tube second end; and a single 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, the single debris blocking structure comprising at least two intersecting partitions having line profiles across the delivery tube cross-section and extending longitudinally and continuously substantially the full length of the delivery tube; inserting the tube first end through the vessel opening and into the beverage, so that the tube second end protrudes out of the vessel through the vessel opening; and placing user lips around the tube second end and drawing some of the beverage through the delivery tube; such that some of the debris in the beverage is drawn to the straw first end and abuts the debris blocking structure and is thereby prevented from entering the delivery tube and from lodging and becoming an obstruction within the delivery tube while beverage flows into the tube first end and through the delivery tube and out of the tube second end into a user mouth.
