Abstract: A travel vessel has a vessel body and a stopper, which upon engagement, is movable from an open, drinking, position to a closed, sealed position. The vessel body has a top edge that allows drinking along the entire 360° perimeter; below the top edge is a cup-like portion; below the cup-like portion is a gasket engaging portion; and below the gasket engaging portion are internal threads for receiving and engaging the corresponding external threads of stopper. The upper portion of the stopper has a ledge. The lower portion of the stopper is a depending wall extending from the upper portion with a plurality of small holes circumferentially disposed on the depending wall to allow flow of liquid at a certain fixed flow rate. A gasket works cooperatively with the ledge and is compressed against the gasket engaging portion to seal the vessel body.

The upper portion of the stopper has a ledge. The lower portion of the stopper is a depending wall extending from the upper portion with a plurality of small holes (or slits) circumferentially disposed on the depending wall to allow flow of liquid at a certain flow rate when the stopper is in an open, drink, position. A gasket works cooperatively with the ledge and is compressed against the gasket engaging portion to seal the open end of the vessel body.
