Abstract: A frusto-conical drinking cup which is open at the top and a lid which is removably attached thereto by a "snap" connection. The lid comprises a top wall and an annular skirt depending therefrom. This lid is of a flexible plastic having the property of elasticity to a high degree. It is formed with a slit in close proximity to its periphery and cut on the bias to provide a drinking opening when the lid material is depressed. It is also formed with a straight slit at a site diametrically opposite to the drinking opening and spaced inwardly from the periphery a greater distance than the drinking valve opening. This lid provides a relief valve when the lid is depressed. The lid is fairly thin and is formed with a generally circular reinforcing rib spaced from its periphery and another reinforcing rib between the slit and arranged diametrically of the lid.

Abstract: A decanter for hot or cold liquids, comprising a cylindrical receptacle having an open top and a cover detachably mounted on the receptacle at its open top. The cover consists of an upper annulus and a skirt of larger diameter than the annulus and connected thereto by a shoulder. Portions of the skirt and the annulus are spaced apart to provide a groove which receives the upper edge portion of the receptacle with a sealing fit. A top wall is integral with the annulus and is tilted with respect to a plane normal to the axis of the receptacle. This top wall is formed with a drinking opening adjacent its periphery and a relief vent diametrically opposed to the drinking opening and also adjacent to the periphery of the top wall. Depending from the inner face of the top wall and between the drinking opening and vent are a pair of spaced posts.
