Abstract
A detent and numerical indicia are associated with a cap for a water treatment apparatus to keep track of how many times a bottle in which the treatment apparatus is disposed has been filled and emptied, to provide for periodic replacement of the filter media. The treatment apparatus is for attachment to a bottle with an opening at a neck portion, and includes an elongated tube, a cartridge containing water treatment media connected to one end of the tube, and a cap for capping the other end of the tube. The cap includes a body having through-extending passages therein, and a top which is movable with respect to the body to selectively cover or uncover the passageways. A detent is associated with the cap body and the top for providing detented rotation of the top with respect to the body. Indicia are associated with the cap top and the cap body for indicating each detented position. Thirty-one Arabic numbered positions and another blank position may be provided as the indicia, cooperating with an arrow that is stationary. Each time the bottle is filled the cap top is rotated one position with respect to the body, and once the last indicia is indicated on the top, the filter is replaced. An adaptor connects the tube to the filter cartridge, and the adaptor can also include water treatment media.
