Abstract: An air freshener canister includes a container, a nipple thereon and a cap threadably matable therewith. The cap can be positioned along the length of the nipple from a closed position with the cap rim against the exterior surface of the container and an open position wherein there is spacing between the rim and exterior surface. A volatile liquid in the container emits air freshener vapors. A wick runs from the liquid to the nipple. When the cap is in the open position, vapors escape from the wick through the spacing. When the cap is in the closed position the vapors are prevented from escaping. When the cap is removed from the nipple the container may be refilled with the volatile liquid. The escape of vapors may be increased or decreased by positioning the cap on the nipple to increase or decrease the spacing.
