Travel cup or mug, featuring easy opening, automatic closing, airtight valve means

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”. The valve means are made to open when manual pressure is exerted onto the Crossbeam ( 140 ). Various methods of acting upon Crossbeam ( 140 ) are comprehended. Said valve means automatically close upon release of manual pressure. A Cover Disk ( 225 ) provides an ideal surface for logo or other advertisement, as said surface is presented to the user's vision each time user drinks from the invention. Cover Disk also serves as support for the mechanisms delineated in the specification, which comprehend activating on Crossbeam ( 140 ) through use of a Button, Pusher ( 215 ), Lever ( 235 ), Trigger ( 245 ), etc.
