A method for coating a paper drinking straw, an apparatus for coating a paper drinking straw, and a coated drinking straw assembly are disclosed. The apparatus includes a dipping tank containing a liquid bath for coating a straw when submerged in the liquid and a straw engagement means for submerging the straw in the bath. The method includes receiving an uncoated paper drinking straw and submerging the straw in a bath containing a water-resistant and/or a water-soluble coating. The drinking straw assembly includes an elongate tubular body and a coating that has been applied to all surfaces of the straw by submerging the body in a bath containing the coating.

Paper products can be made from cellulose derived from corn husks. A method of making paper products may include obtaining corn husks, extracting cellulose fiber pulp from the corn husks, forming a paper sheet from the extracted cellulose fiber pulp, adding a chitosan acetic acid solution having a concentration of at least 5 wt. % chitosan to the paper sheet, forming the paper product from the paper sheet, and coating the paper product with a paraffin wax.

A self-cleaning suction device has a user's suction end that self-sanitizes externally and internally before and after use, as well as self-sanitizes internally during use. A cover opens to reveal the user's suction end within a containment unit. As the cover opens, the suction end travels from a lower chamber, proceeds through a middle chamber of a sanitizing agent, and is presented for use. After suction is complete, the suction end retracts through an upper chamber with, a scraping feature that removes debris from the outer surface of the mouthpiece, and proceeds down through the middle chamber of a sanitizing agent and a scraping feature that removes debris and the sanitizing agent from the outer surface of the user's suction end. Upon the sealing closure of the cover, the upper and middle chambers are flushed with a sanitizing agent, which is suctioned away along with any collected debris. The user's suction end resides within a lower chamber and can be decontaminated by a UV-C light entering into the lower chamber and/or corresponding chambers. The suction device can also include a liquid-hydration delivery system.

The present invention relates to a straw (1), a straw assembly (2) and a cup assembly (3). The straw (1) comprises first holes (13) in an upper half and second holes (14) in a lower half both arranged at the lateral surface of the straw (1). A sleeve element (20) can be arranged coaxially to and around the straw (1) to form a straw assembly (2). The sleeve element (20) is configured to close the first holes (13) in a first position and the second holes (14) in a second position. The straw assembly (2) can be arranged in a cup assembly (3). As the sleeve element (20) is also configured to float in a liquid the sleeve element (20) is moved through the force of buoyancy either to the first or the second position depending on the inclination of the cup assembly (3) with respect to the force of gravity. This provides a solution for any angle drinking.
