Abstract

An air freshening pad for use, in all enclosed spaces including cars, consists of an impregnated pad which is en-closed in two wrappings, the outside wrapping being imper-meable and the inside wrapping being of slightly permeable wrapping, both wrappings being pref. of cellulosic mater-ial. In use the outer impermeable wrapping is removed allowing the deodorant to pass to the atmosphere through the slightly permeable wrapping. When the effectivenedd of the deodorant begins to decrease the slightly permeable wrapping is removed. The air freshening effect is controll-ed and extended over a long period of time.
