A drinking cup having a body portion and a removably attached cover including an offset drinking spout and an offset vent aperture. The drinking spout and the vent aperture are each surrounded by wall members which depend generally away from an interior surface of the cover. An air inlet flow control valve is coupled to the wall member surrounding the vent aperture while a liquid outlet flow control valve is coupled to the wall member surrounding the spout. Each flow control valve includes a domed elastomeric member containing a slit allowing for passage of a selected fluid therethrough. The domed portions are each surrounded by a generally circular isolating channel, and outside of each isolating channel is a perimetral portion for connecting the flow control valve to the depending wall portion of the cover. Fluids passing through the slits achieve substantially only a one-way passage as the domed curvature substantially prevents any backflow. Vacuum must be applied on the convex side of the domed portion for sufficient elastomeric displacement to allow a fluid to pass through the slit. In the absence of such a vacuum, the sides of the slit are maintained in contiguous contact thereby preventing any transfer of liquid or air across the respective flow control valve. Coupling means are provided for coupling the flow control valves together, and may include handle portions integrally attached to the perimetral portion and including joining means for joining the handle portions together.

A self-sealing drinking container includes a cup body having a hollow interior for holding and dispensing a liquid, and a lid assembly which fits sealingly on the cup body. The lid assembly has an inlet passage with an inlet valve in communication therewith, and an outlet passage with an outlet valve in communication therewith, each of the valves including a resiliently flexible diaphragm member. In a preferred embodiment, each of the inlet and outlet valves includes a cage having an open top and an open bottom to allow fluid passage therethrough, the cage having a seat formed therein for receiving a diaphragm member. The diaphragm member is located seatably into the seat so as to selectively seal thereagainst and thereby prevent fluid flow therepast. A locator post in each cage centrally abuts the diaphragm member thereof to ensure its seating. A predetermined level of fluid pressure differential across each diaphragm member causes, respectively, the diaphragm members to concavely bend (or flex) away from their respective seat and thereby allow fluid flow through the valves. However, below the respective predetermined levels of fluid pressure differential, the diaphragm members sealingly abut their respective seats, thereby sealing the cup.

U.S. Pat. No. 7,204,386
Inventor: Noun E. Hakim
Issued: Apr. 17, 2007
An improved no-spill cup construction and valve assembly which provides an extremely secure seal against accidental liquid flow from the cup spout. The act of sucking at the cup spout creates negative pressure or a partial vacuum against a valve near the spout, causing the valve to invert which unblocks an opening in the valve. When the opening is unblocked, liquid can flow freely through the valve and spout. When not in use, the valve sits in a resting, closed position, with the valve pressed against a center seal-off, sealing off the opening in the valve assembly. The closed position provides an extremely secure seal against fluid leakage, such that inadvertent spills or even deliberate attempts to force liquid outside of the cup, such as by turning the cup upside down, or shaking the cup, are ineffective. The cup assembly further allows liquid flow to be regulated between regular or maximum flow and minimal flow levels or rates by rotating the position of the valve assembly in the cover of the cup.

International Patent Application Number WO 01/12031
Inventor: Robert P. Wharton
Issued: Feb. 22, 2001
A cup is disclosed which includes: a sealingly engageable lid (10) having a drinking spout (14) located thereon, a tubular passage (20) formed between inner surface of the lid (10) and/or spout (14) and a detachable member (18) located on the lid (10), the passage (20) having one end in communication with the inside of the cup and the other end in communication with the outside of the spout (14) and being of such a diameter such that air cannot readily bubble past liquid inside it. When such a cup is inverted, the head of liquid inside lowers the pressure of the air above the liquid, and liquid therefore starts to move downwardly through the passage. This continues until the reduction in air pressure above the liquid just balances the pressure of the liquid head, when further movement of liquid ceases. (The fact that air cannot bubble past the liquid in the passage ensures that the air pressure is not restored while the cup is inverted or reclined). Thus the capacity of the passage should be great enough to contain this amount of liquid without reaching the exit and therefore spilling.
While these receptacles may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
SUMMARY OF THE PRESENT INVENTION
