Abstract
A disposable cup cover fabricated from a die, wherein a die ordinarily used for the fabrication of disposable cup covers, includes an additional configuration which causes the cup cover to have a separatable pie shaped mouth piece which a user can bend out of the way in order to drink from the cup and with an edge which will mate with a slot in the body of the cover which will receive it and hold it rigidly until it is desired to close the cover again.
