摘要： Disclosed is a disposable container lid for releasably mounting to a disposable container. The lid includes a central portion having a rim engaging means about the circumference of the central portion. An access strip is provided by a pair of tear impressions extending from the rim engaging means to a hinge means located in the central portion. By breaking the tear impressions, the access strip can be pivoted back from the hinge means to create an access opening through the lid. The central portion of the lid has a primary slit therein which is preferably arcuate. At each end of the primary slit there is a tab forming slit, each forming an inwardly directed retaining flap. A deflection flap is formed by the combination of the primary slit and the tab forming slits. To lock the access strip in a non-interfering position, it is folded back and pushed against the central portion of the lid thereby causing the deflection flap to deflect down toward the contents of the container. The small retaining flaps spring past the sides of the access strip and thus overlap such sides holding the access strip in abutting, face-to-face position with the deflection flap. The access strip can be released from the retaining flaps merely by directing upward force against the access strip causing the retaining flaps to deflect upward and spring past the access strip. The access strip can then be reseated on the rim of the cup if desired.
