Abstract
A drinking straw that can be used to dispense a substance such as vitamins, pharmaceuticals, or diet supplements that is stored inside of the straw body. The straw includes a one-way liquid flow valve at one end of straw that prevents drawn liquid and any of the dissolved materials from returning to the initial liquid source that is drawn through the straw when the straw is not in use. The straw may include a one-way valve or crimp for acting as a one-way valve.
Claims1
A dispensing drinking straw for containing a substance that can be dissolved in a liquid drawn through the dispensing drinking straw comprising:
- a drinking straw body that includes a long, thin hollow cylinder, for drinking a liquid, said drinking straw body being crimped near a first top end forming a first crimp and said straw body being crimped near a second bottom end forming a second crimp, and forming an interior chamber between said first crimp and said second crimp;
- and
- a substance deposited in the chamber formed between the first crimp and the second crimp in the straw body, said second straw body crimp having memory so that the force of liquid through the straw will open the crimp to permit liquid to flow there through and when the drawing force of liquid is removed, the second crimp will return to its original closed position.
