A cap includes a frangible path defining a flap to be formed when the frangible path is broken in response to a blunt probe penetrating the cap. Advantageously, the frangible path may be disposed substantially in a first plane which may be both (1) parallel to a second plane in which an opening of the bottle (to which the cap is attached) is disposed, and (2) substantially perpendicular to the direction in which the bottle is moved to cause the probe to penetrate the cap. The frangible path may be defined in the first plane so that a hinge portion of the flap remains connected to the cap after the probe has been inserted therein. When the probe is later removed from the cap, the flap may be caused to close so that water remaining in the water bottle is inhibited from exiting the water bottle. The hinge portion of the flap may be made of a material having a shape memory sufficient to bias the flap at least slightly toward the closed position but that is flexible enough that the water pressure of the water remaining in the bottle has a substantial effect in further biasing the flap toward the closed position.
