초록 ▼

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.

[ What is claimed is:] [1.] A cap for a drinking cup having a body portion capable of holding a fluid, comprising:a cover capable of removable attachment to the body portion and including a top wall defining at least one hole and a vent aperture disposed through the cover, the at least one hole disposed separate from the vent aperture so that when the cover is attached to the body portion, air may enter the body portion through the vent aperture as liquid exits the body portion through the at least one hole;a first wall member disposed surrounding the vent aperture and mounted to and projecting generally away from an interior surface of the top wall;a second wall member disposed surrounding the at least one hole and mounted to and projecting generally away from the interior surface;an air inlet flow control valve mounted to the first wall member, capable of fluid connection with the vent aperture and including an elastomeric first domed portion defining a normally closed first slit therethrough, so that when the cover is attached to the body portion, the first domed portion is capable of movement whereby the first slit opens generally towards the body portion upon occurrence of a pressure differential across the air inlet flow control valve with relatively lower pressure within the drinking cup, and remains closed in the absence of a pressure differential across the air inlet flow control valve and upon occurrence of a pressure differential across the air inlet flow control valve with relatively higher pressure within the drinking cup; anda liquid outlet flow control valve mounted to the second wall member, capable of fluid connection with the at least one hole and including an elastomeric second domed portion defining a second slit therethrough, so that when the cover is attached to the body portion, the second domed portion is capable of movement whereby the second slit opens generally away from the body portion upon occurrence of a pressure differential across the liquid outlet flow control valve with relatively higher pressure within the covered drinking cup, and remains closed in the absence of a pressure differential across the liquid outlet flow control valve and upon occurrence of a pressure differential across the liquid outlet flow control valve with relatively lower pressure within the covered drinking cup.
