  • Publication number: 20060110144
    Abstract: A bottle adapted to be operatively interfitted into a plurality of different housings for liquid vaporization devices. The bottle is a modification of the bottle disclosed in U.S. Pat. No. 6,659,301 that interfitted to a first and second vaporization device and has a circular recess formed in its wick holder so as to receive a downwardly extending circular ring of a third vaporization device to thus enable the new bottle to be interfittable to that third vaporization device. At the same time, the modifications have dimensionally retained an annular collar that surrounds the neck of the bottle which enables the bottle to still be intermitted into the first vaporization device as well as a fourth vaporization device manufactured by the present assignee. As such, the same bottle is operatively interfitted into a first, second, third and fourth vaporization devices, all of differing dimensions and of at least three different manufacturers.
