Abstract: 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.

Abstract: A cap for use with an associated container comprises a measuring spout which is wholly contained inside the cap and does not protrude into the container. The cap comprises a cap wall which is adapted to provide an opening in which the spout is seated. The spout comprises a forward wall and at least one side wall which forms an open-topped hopper. The spout pivots between a closed, filling position and an open, dispensing position. The spout is formed from a visually translucent material, such as any of a number of commonly available plastics. Volumetric measuring indicia are disposed on an outer surface of the forward wall of the spout, thereby allowing a user to determine and adjust the desired volume of the material prior to discharge of the material from the spout. The cap is also provided with upwardly and inwardly tapered portions which guide the material into the hopper.

Abstract: A measuring canister is disclosed for storing any of a variety of particulate solid particulate materials, and for dispensing in a controlled manner a portion of the stored particulate material selected by the user to be any portion up to maximum volume, while preventing spillage from or dispensing of the remaining particulate material. The interior of a container having an open top is divided into a storage compartment and a measuring dispensing compartment by a partition having a notch. A generally planar flap is hinged to a cover having a dispensing orifice proximate to the measuring compartment, with the cover removably attached to the container.
