Abstract
A tobacco smoke filter having a non-integral core of components [2, 3] joined and held in longitudinal alignment by a strip [1] which extends only partially around the core circumference to leave a gap [7] extending longitudinally of the core between the longitudinal edges [8] of the strip, and an outer wrap [5] which engages fully around the core and strip and provides--e.g. via perforations [9]--for the lateral ingress of external ventilating air therethrough and through the longitudinal gap.
Claims9
A tobacco smoke filter rod of finite length having an elongate non-integral core of components joined and held in longitudinal alignment by one or more strips each extending along and only partially around the core circumference to leave at least one gap extending longitudinally the full length of the core between longitudinal strip edges and through which the core is exposed to ambient air so that ventilating air may enter the core laterally.
A tobacco smoke filter having a non-integral core of components joined and held in longitudinal alignment by plugwrap which extends only partially around the core circumference to leave a gap extending longitudinally the full length of the core between the longitudinal edges of the plugwrap, and an outer wrap which engages fully around the core and plugwrap and provides for the lateral ingress of external ventilating air therethrough and through the longitudinal gap.
