Improved straw, essentially characterized by being constituted by a single-piece tubular element which has a flexible intermediate section at a variable distance from the suction end so that when exerting an involuntary or voluntary excess pressure, at its suction end said intermediate section assumes a curvature, forcing the two end portions of said one-piece tubular element to be in angular position with each other with said flexible section acting as a joining vertex between both end portions.
