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.

Un bouchon comprend une partie friable définissant un rabat qui se forme lorsque la partie friable se brise lors de la pénétration d'une sonde arrondie dans le bouchon. Pour plus d'efficacité, la partie friable peut être disposée sensiblement dans un premier plan à la fois (1) parallèle à un deuxième plan dans lequel une ouverture de la bouteille (à laquelle le bouchon est relié) se trouve, et (2) sensiblement perpendiculaire à la direction dans laquelle on déplace la bouteille pour introduire la sonde dans le bouchon. La partie friable peut être définie dans le premier plan de sorte qu'une charnière du rabat reste reliée au bouchon après l'introduction de la sonde dans ce dernier. Lorsque la sonde est ensuite retirée du bouchon, le rabat peut se fermer empêchant ainsi l'eau restant dans la bouteille de sortir. La charnière du rabat peut être formée dans une matière à mémoire de forme suffisante pour contraindre le rabat, au moins légèrement, en position fermée, mais suffisamment souple pour que la pression de l'eau restant dans la bouteille exerce un effet sensible de contrainte du rabat en position fermée.
