| 20100147862 | READILY CLEANABLE SPILL-RESISTANT DRINKING VESSEL AND VALVE - A no-spill drinking vessel includes a cup, lid, spout and valve assembly. The valve assembly includes: a liquid-out valve with hinged flap, air vent check valve, air and liquid inlets, air and liquid outlets, and a mechanism for retention to the lid. The valve assembly is constructed from one or two inexpensive molded elastomeric components. In usage mode these components cleave sealingly together by the resilient returning forces they exert on each other's complementary interlocked geometries. | 06-17-2010 |
