The present invention is directed to a device that can easily deliver water or other sources of hydration from a bottle, directly to a user during exercise without the use of a traditional hydration bladder. The present invention features a hydration device for allowing delivery of a fluid from a container with a cap with a hole. The hydration device may comprise an outer tubing affixed around the hole and an inner tubing disposed within the outer tubing. The inner tubing may extend past both ends of the outer tubing, slide freely within the outer tubing, and extend to the bottom of the container. Both ends of both tubings may be always open. The fluid may be delivered from the container through the inner tubing when suction is applied. Air may be delivered from the outer tubing to the pre-existing container to prevent collapsing of the pre-existing container.

The object of the application is a telescopic paper drinking straw comprising: a first straw with a first outer diameter, a second straw with a second inner diameter, the first straw with the first outer diameter being situated at least partly inside the straw having the second inner diameter, coaxially with the straw having the second inner diameter, characterised in that the first straw has at east two locking elements protruding from the outer surface of the first straw, and the second straw has at least two locking elements protruding from the inner surface of the second straw.

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.

Apparatuses, systems, and methods are presented for a buildable drinking straw. A segment of a drinking straw is hollow. A segment has a narrow end and a wider end. A wider end of a segment of a drinking straw is opposite a narrow end of the segment of the drinking straw and has a wider diameter than the narrow end of the segment of the drinking straw so that the segment of the drinking straw tapers in diameter from the wider end to the narrow end of the segment of the drinking straw.

An access and/or withdrawal system. The withdrawal system may be used with a container system having an access portal is disclosed. The withdrawal system may be selectively adjustable. The withdrawal system may include a filter member.

A portable straw that is encased in a protective sleeve. The protective sleeve attaching to a connector sleeve that is fused with the surface of the straw and not to the straw sections themselves. The connector sleeve and the cap functions as a handhold to deploy and retract the straw without touching the surfaces of the straw that are submerged inside a cup or exposed to user's mouth. A convenient harness made of elastic band may be deployed along an arm of a user for holding the portable collapsible straw when not in use.

An extendable straw includes a relatively smaller diameter tube, a relatively larger diameter tube, and a collar. The smaller diameter tube includes a radially enlarged section adjacent one end. The larger diameter tube receives the smaller diameter tube and is more flexible than the smaller diameter tube. The radially enlarged section contacts and seals against an inner surface of the larger diameter tube. The collar is connected at a non-drinking end of the larger diameter tube, the collar being more rigid than the larger diameter tube and receiving the smaller diameter tube. The smaller diameter tube is movable in an axial direction with respect to both the collar and the larger diameter tube. At least one of the collar and the larger diameter tube cooperates with the radially enlarged section to inhibit further axial movement of the smaller diameter tube with respect to the collar beyond an extended position.

A paper drinking straw is provided, including a main tube and a sub-tube. The main tube includes a first neck segment, and the sub-tube is movably sleeved with the main tube. The sub-tube includes a second neck segment and is movable in a stretching direction to increase a length of the fourth segment protruding beyond the main tube. When the sub-tube is moved to a predetermined position, the second neck segment is restricted to the first neck segment, and the sub-tube is unmovable in the stretching direction.

A reusable straw assembly is present herein. In particular, the straw assembly includes at least one, although in some cases, a plurality of cylindrical straws having different diameters, a brush assembly including a brush stem terminating with a brush head at a distal end thereof, and a housing comprising a body and at least one end cap. The brush assembly, and in particular, the brush stem is fixed to the end cap. The brush stem is axially disposed relative to the one or more straws, which are then disposed within the housing. In the case where the assembly includes a plurality of reusable straws, the plurality of reusable straws are disposable in a coaxially nested configuration and retained on the brush assembly until manually released by a user.

A non-spill drinking cup system includes a container; a lid assembly that is removably attachable to the container, comprising an aperture; and a drinking tube, wherein the drinking tube extends through the aperture, the drinking tube including an open end, a closed end, and a side wall; and a drinking valve, wherein the drinking valve includes at least one elongate slit disposed within the side wall.
