Patent number: 6357620Abstract: 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 member near the spout having an opening therein, causing the valve member and opening to move off of a protruding member, thereby unblocking the 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 opening in the valve sitting on a protruding member and pressed against the protruding member's base, 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.Type: GrantFiled: March 18, 1999Date of Patent: March 19, 2002Inventor: Nouri E.

When the container is rotated to engage the dispenser and advance it into position, the center port of the plug and central port of the dispenser align since they are on the same axis. The radial port of the dispenser is aligned with the annular groove in the plug, enabling fluid communication with the second port in the plug irrespective of the rotational orientation.Type: GrantFiled: June 28, 1993Date of Patent: April 5, 1994Assignee: The Hoover CompanyInventor: Nick M.
