Claim:
A no-spill drinking cup comprising: (a) a vessel having a cavity with an open end; (b) a lid cover, attachable to said vessel for closing the open end of said vessel's cavity; when in a closed state, said lid cover constituting a boundary defining an interior and an exterior of said cup; said lid cover defining at least one opening for allowing liquid communication from the interior to the exterior of said cup; (c) a valve assembly attached to said lid cover and configured in relation to the at least one opening such as, when said lid cover is closing said vessel's open end, to provide a controlled liquid communication route from the cavity of said vessel to the exterior of said cup, said valve assembly comprising: one or more valve bodies for liquid control, said bodies collectively having at least two faces and at least one of said valve bodies being comprised of an elastic material; said one or more valve bodies for liquid control being arrangeable to bring said at least two faces into mutual adjacency with portions in mutual sealing abutment, such that the faces create an interface; the interface between the at least two adjacent face portions defining an enclosed channel comprising: an inlet for accepting fluid from the cavity, an outlet for dispensing fluid to the exterior of the cup, and a conduit connecting said inlet to said outlet and configured to provide fluid communication from said inlet to said outlet; said valve assembly further comprising: a flap constituted on the at least one valve body composed of an elastic material, said flap configurable within the channel such that said flap selectively blocks the fluid communication; the abutted portions of the at least two faces, being separatable along a path parallel to the conduit and extending from the inlet to the outlet such that, when separated, the surfaces of said flap and all formerly interior surfaces of the channel become exposed, exterior surfaces.
