Cigarettes are made with a filler comprising an outer annulus of tobacco surrounding a core of a tobacco or other material different from that in the outer annulus. The annulus tobacco may be showered to form a layer which is then bent into a U-section to receive the core, after which further tobacco is showered on to the U-section plus core to enclose the core in tobacco. Alternatively the core material may be incorporated in the filler by pneumatically rolling a carpet of an annular of tobacco...

A cigarette filling pressure indicator which, in a preferred arrangement, is arranged to allow the cigarette rod to pass continuously through it before the rod is cut into cigarette lengths. The indicator includes a pressure chamber which compresses an inadequately filled part of the rod, and a comparator device which compares the section of the rod before and after compression so as to detect an inadequate rod filling.

A cigarettes case comprising (i) a case body with a top partially cut away to provide a top opening located adjacent to one side of the case body for taking out a cigarette from the case body, with a vertical slit provided in the one side, and with an opposed, open side for supplying cigarettes into the case body 1, (ii) a removable side wall member for closing the open side, and (iii) a slider located in the case body and having a lid portion, an upright portion, and a projecting bottom portion...

An improved composite cigarette comprising a core of lesser quality tobacco smoking material surrounded by an annulus of higher quality tobacco smoking material is described. The improvement resides in the provision of an increased quantity of the annulus material at the lighting end of the cigarette, so as to increase the initial flavor impact and thereby provide more uniform smoke taste characteristics along the length of the cigarette.

Apparatus for testing the wrappers of cigarettes for leaks includes means for producing a series of first electrical signals indicative of the leakage flow through the wrappers of successive cigarettes, a comparator device for producing an ejection signal to eject each faulty cigarette, and an averaging device which responds to the running average level of the first signals and continuously varies the limit of the first signal which results in the production of an ejection signal by the comparat...

Testing cigarettes for leaks by passing them endwise through a suction chamber which draws air from atmosphere through the end of a cigarette and through its wrapping and the pressure of which fluctuates according to the air flow.

This invention relates to a structure and combination of materials for the removal by filtration of certain combustion products carried in the smokestream of a burning cigarette, said filtering means being optionally attachable or integrally attached upon the end of a cigarette at the mouth end thereof.

Packaging is provided in which smaller than standard-size cigarette packages are packed in a carton designed to permit the cigarette packages to be marked in a tax marking machine for marking standard-size cigarette packages.

A filtered cigarette in which the inner end of the filter is tapered so that there is a variable drawing resistance along different longitudinal planes of the filter and in which the space between the tobacco and the inner end of the filter provides a chamber in which the tobacco smoke may be cooled; additionally, there is a relatively even draw resistance throughout the entire smoking cycle.

A filtered cigarette in which the upstream end of the tobacco smoke filter is disposed along a single inclined plane so that there is a variable drawing resistance along different longitudinal planes of the filter and a progressive build-up of tars and nicotine on the inclined plane and in which the space between the tobacco and the upstream end of the filter provides a chamber in which the tobacco smoke may be cooled by air inhaled through apertures in the cigarette wrapper. Additionally, there...
