The lid includes a peripheral rim wall that snaps down around the upper edge of the can to mount the lid on the can; the rim wall seals against leakage across the can-lid interface. A hollow drinking straw extends through the lid so that a portion of the straw is exposed for drinking purposes; a second portion of the straw extends downwardly into the can for extraction of liquid from the can.
