Abstract
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.
Claims9
A fluid flow regulating apparatus, adapted for sealed engagement to a drinking straw, comprising:
- a body having a first end;
- said body having a second end opposite said first end;
- an exit aperture at said second end;
- an axial passage defined by a sidewall, said axial passage running through said body in communication with said exit aperture, and an opening at said first end adapted for a sealed engagement with a drinking straw;
- a sealing member having a circumferential surface sized for a translating engagement within said axial passage;
- said sealing member having a first end having an annular angled surface;
- an annular seat surrounding said exit aperture, said annular seat formed at an angle complimentary to said annular angled surface;
- said sealing member having a seated position blocking communication of said exit aperture with said axial passage;
- said sealing member having a second position allowing said communication of said exit aperture with said axial chamber;
- a gap formed between said circumferential surface and said sidewall;
- and
- said gap providing a passage for a communication of a fluid flow from said straw to said exit aperture with said sealing member in said second position;
- and
- said sealing member in said seated position causing a cessation of said fluid flow.
