US Patent 9167928 Flow limiting drinking straw

A fluid flow regulating component adapted for sealed engagement to a drinking straw is provided to prevent excess fluid flow to users drinking with a straw. The device has a body adapted to engage the straw at one end to direct fluid flow through an axial cavity to an exit aperture. A translating valve body within the axial cavity ceases fluid flow during periods of excess acceleration or volume. A secondary valve may be engaged to prevent backflow of the fluid.
