<p>An adjustable-delivery cigarette and method for producing same, whose strength delivery may be altered by the consumer in a range between higher and lower values. The cigarette includes a tobacco rod (12), with paper wrapper (14), and the filter assembly (16). An over-wrap (18) encircles the filter element (16) and may also join the filter element to the tobacco rod. The overwrap has an adjustment zone (22) formed therein, which may be in the form of a circumferential slot. The circumferential slot may extend partially through the overwrap, or may extend completely through the over- wrap and partially through the filter plugwrap (20). In the latter instance, the filter plugwrap should be relatively impervious to airflow. Application by the consumer of a bending moment to the filter assembly results in the adjustment zone being ruptured, allowing a greater degree of air dilution, resulting in a decreased perceptible strength to the consumer. This adjustable-delivery cigarette can be manufactured conveniently using laser apparatus known to the art, modified and adjusted to achieve the desired levels of penetration.</p> |
