Question about Holy Water

Our parish has a -- for lack of a better word -- dispenser filled with Holy Water that apparently anyone may use. What sort of container is appropriate to take Holy Water home in? I know some folks annoint their kids with Holy Water as a regular blessing -- how else may it be used?

(And please forgive the silly questions -- as I've said numerous times, the Catholic faith is so complex, I keep unearthing wonderous new traditions and practices that I can make my own.)
