The refill further includes a plug and a wick having a first end positioned within the bottle and a second end extending out of the bottle, the wick further defining a longitudinal axis. The plug is coupled to the neck of the bottle, the plug retaining the wick within the bottle. At least a portion of the inner surface of the rim is tapered at an angle of between about 2 and about 9 degrees with respect to the longitudinal axis.
