Abstract: A beverage container lid includes a round rim and a flange extending beyond the rim. The rim and flange form an outer perimeter having a plurality of local maxima, at least one of which is proximal to a spout, such that the container, when tipped over with the spout oriented downward, will gravitationally roll until the rim rests on one of a plurality of local minima, which in embodiments requires rolling through an angle of no less than 30 degree and/or no more than 90. The local maxima can be equally spaced about the center of the lid and equidistant from the lid center. Between each adjacent pair of local maxima, the perimeter of the lid can be shaped substantially as an arc of a circle, where the circles can have equal radii. In some embodiments the flange extends beyond the rim everywhere.

Abstract: A container lid and base assembly includes lid and base stacking features, as well as base chamfers that align with vents provided in the lid. When a plurality of the container assemblies is stacked, the lid and base stacking features nest with each other, while the chamfers align with corresponding vents in the stacked assemblies so that none of the vents is blocked by a next-higher container assembly. The stacking features can be centrally located, and the vents can be peripherally located. A plurality of the container assemblies can have differing sizes and/or shapes, while including mutually compatible stacking features, thereby enabling container assemblies of differing sizes to be stacked without blocking any of the vents thereof. The vents can be holes or “C” vents. The lid and/or base can be manufacturable by thermoforming. The lid and base can be separate, or joined by a hinge.

Abstract: A beverage container lid includes a round rim and a flange extending beyond the rim at least proximal to a spout, such that the container, when tipped over with the spout oriented downward, will gravitationally roll until a height of the container's center of mass reaches any of a plurality of local minima. The lid can be configured such that rolling through an angle of no less than 30 degree and/or no more than 90 degrees is required. In some embodiments the flange extends beyond the rim only proximal to the spout, such that the rim contacts an underlying table over a continuous angular range beyond the flange. In other embodiments, the flange extends beyond the rim everywhere, and has a plurality of maximum radii with a plurality of minimum radii interspersed therebetween. In some of these embodiments the flange includes at least one flat, straight line segment.

Abstract: A cooking appliance includes a door assembly having a main frame provided with an inner, central opening. A glass panel is secured to the main frame portion across the inner, central opening and an overlay member is adhesively secured to the glass panel through a plurality of adhesive elements. The overlay member includes top, bottom and opposing side sections that collectively define an outer, central opening. The adhesive elements establish airflow passages that extends longitudinally across the door assembly between the glass panel and the overlay member. The overlay member also includes first and second flanges that are arranged along the top and bottom edge sections respectively. Third and fourth flanges are provided on respective upper and lower edges of the outer central opening. The flanges, together with the adhesive elements, ensure the presence of the airflow passages.
