A liquid treatment mechanism may easily be snapped on, or otherwise attached, to the neck of the single orifice bottle, such as a standard five gallon water bottle. An end cap is connected to a first tube of the liquid treatment mechanism, the liquid treatment element (such as activated carbon) disposed in the first tube and extending from the second end of the first tube to a termination position near, but spaced from, the first end of the first tube. A liquid inlet allows for the passage of liquid from exteriorly of the first tube into contact with the liquid treatment element. A dispensing tube (which may include a cyst or other particle filter) is disposed adjacent the first end of the first tube and extends from the liquid treatment element. An air inlet (e.g., a free about 0.02-0.1 inch diameter hole) is disposed in the first tube near its first end and exteriorly of the dispensing tube. A sheath of porous material may wrap the activated carbon, which may be either in hollow tubular or block form. Non-potable water may be treated by breaking an ampoule containing about 300 mg of calcium hypochlorite which is placed into the bottle and is dissolved by the non-potable water before the first tube is inserted into the bottle, and the water dispensed through it.

An elapsed time indicator can easily indicate time periods of over a month, and is extremely versatile, for example being utilizable in a cap of a water bottle. The indicator includes a substantially transparent and substantially straight tube having first and second ends, an interior and an exterior, with a viscous liquid substantially filling the interior of the tube. A visible indicator, such as a polypropylene spherical bead, a magnetite/wax bead, or a fluid immiscible in the viscous liquid, is immersed in the viscous liquid and dimensioned and positioned with respect to the tube so that it can travel from the first to the second end in a known predetermined period of time when the tube is generally vertical. The time it takes for travel may be precisely calculated. The indicator may be held in a stationary position at one end of the tube, e.g. by clamping a flexible tube end, or using a magnet, prior to initial use. A scale may indicate the relative position of the indicator, and more than one indicator in the same tube, or different in-line and adjacent tubes with different indicators, can be provided.
