  • Bottle and filter
    Patent number: 5139666
    Abstract: A water dispenser supports a bottle having a filter neck accommodating a water filter and a fill neck closed with a cap equipped with a water refill counter. The cap can be removed from the fill neck to allow the bottle to be filled with water without removing the filter from the filter neck. The filter neck has a plurality of inwardly directed projections that are engaged by the filter to position the filter in the filter neck and prevent the filter from being pushed into the chamber of the bottle. A ring having an air bleed hole mounted on the filter neck engages the filter to retain the filter on the filter neck.
