A unitary nonspilling container cover comprises a pair of similarly dimensioned discoid sections each having a peripheral channel and a flexible hinge connecting their peripheries. The two sections are oriented so that the second section can be flipped over onto the first so that the peripheral channel on the second section engages over the peripheral channel on the first section to provide a shallow space between the two sections bounded by peripheral seal. An array of small openings are provided in the first section leaving a relatively large contiguous imperforate area in that section. A removable tab is provided for forming a drinking opening in the second section, the tab being positioned so that it is disposed opposite the imperforate area in the first section.

A cover for a container comprising A. a first discoid cover section, said first cover section including 1. a peripheral channel, said channel being arranged to resiliently engage over the rim of a cup or other container, 2. an array of relatively small openings, and 3. a relatively large contiguous area which is imperforate, B. a second discoid cover section having substantially the same dimensions as the first section, said second cover section having 1. a peripheral channel arranged and adapted to resiliently engage over the channel on the first cover section, and 2. means in the second cover section for producing a defined opening therein, C. an integral hinge connecting the two cover sections so that the second section can be flipped over and superimposed on the first section with its channel engaging the first section channel so as create a shallow passage between the two sections which is bounded by a peripheral fluid-tight seal, the array of openings in the first section and the opening producing means in the second section being positioned relative to the hinge so that, when the two sections are superimposed, the opening producing means is positioned directly above said imperforate area of the first cover section.
