Abstract: This invention is a Travel Mug, featuring airtight, no leak, easy opening, automatic closing, valve means. The invention provides the benefit of ensuring no beverage emerges from the inside of the container unless the opening mechanism is activated. Even with the additional pressure of very hot coffee, and even when shaken, the sealing mechanism remains leak-proof. This is accomplished by utilizing standard Rubber O-rings (125). Rubber O-rings (125) are positioned in intimate contact with O-Ring Seats (85) while surrounding Counter-bores, Bottom (90). A Spring (150), applies distancing pressure between Crossbeam (140) and Spring Seat (75). Said distancing pressure is transmitted to Qty 2, Stem (120), to Qty 2, Disk, O-ring (105), to Qty 2, O-Ring Groove (110), and ultimately onto Qty 2, Rubber O-Ring (125). Said pressure exerted on Rubber O-Ring (125), between the bottom of O-ring Groove (110) and O-ring Seat (125) causes airtight, leak-proof seals, or “valve means”.
