Abstract: A resilient, modular closure for selectively sealing an opening in a pry tab beverage can. The closure comprises a handle perpendicularly extending from an integral body. The handle is grasped between the thumb and the forefinger of the user. The body comprises a downwardly-projecting, beveled offset adapted to mate with the can opening, and a notch adapted to wedgably engage the pry tab. The ventral surface of the body comprises a circumferential ridge adapted to contact a top of a beverage can to seal around the opening or to mate with a reinforcement channel surrounding the can opening. Raised guides are defined along the dorsal surface of the notch for captivating the pry tab during installation of the closure. A snap fit yieldably engages the rim of the can when the closure is installed. The snap fit comprises a rim-receptive slot. A stop extends rearwardly from the body to contact an inner surface of the rim, and an "L" shaped jaw extends downwardly from the handle.
