An aerosol delivery system is provided, comprising a control body portion including a first elongate tubular member having a power source disposed therein. A cartridge body portion includes a second tubular member having opposed first and second ends. One of the first and second ends is removably engaged with one end of the control body portion. The cartridge body portion further comprises a first aerosol generation arrangement disposed within the second tubular member and configured to operably engage the power source upon engagement between the control body portion and the cartridge body portion. The other of the first and second ends of the cartridge body portion is configured as a mouth-engaging end. The cartridge body portion further includes a second aerosol generation arrangement disposed within the second tubular member between the first aerosol generation arrangement and the mouth-engaging end. An associated method is also provided.

A tobacco smoke filter or filter element comprising: a longitudinally extending core which includes a paper or other non-cellulose acetate containing filtering material and a wrapper engaged around the longitudinally extending core wherein the filter or filter element is readily biodegradable and wherein; the longitudinally extending core includes two plugs of paper or other non-cellulose acetate containing filtering material distanced longitudinally from each other and the wrapper engaged around the plugs of paper or other non-cellulose acetate containing filtering material defines a cavity between the plugs of paper or other non-cellulose acetate containing filtering material; and/or at least one end of the wrapper extends beyond the end of the longitudinally extending core around which is engaged to define a cavity or recess at the end of the filter.

Disclosed herein is a tow band comprising cellulose acetate and a filler. The filler may be selected to have a degradation rate greater than that of the cellulose acetate. The tow band may be bloomed and formed into a filter rod, which may then be incorporated into a cigarette filter. The tow, tow band, and filter structures described herein degrade more rapidly than other known tow, tow bands, and filter structures.

A device for use while burning smoking material and inhaling the resulting smoke is disclosed. The device can include a filter having a recess formed in a surface of a body along a curved face extending from the first end to the second end, the recess extending radially into the body. The smoking accessory can include a capsule containing a flavoring agent disposed within the recess. The device may be received by a first end a tubular member formed to receive a smoking material, that when burned passes smoke into the device.

An article for use with a smoking device that is configured to be insertable into a chamber defined in the smoking device. The article includes an air-permeable filter member that comprises plant-based material that permits a user to combust a smoking device's contents. Upon combustion of a smoking device's contents, the combustible smoking filter may also combust and be smoked.

The invention relates to a smoking article (10) comprising a tobacco rod (12) and a filter, the filter comprising a filter unit (14) comprising a first segment (16) of filtration material; a second segment comprising a tubular element (18) of filtration material upstream of the first segment (16), the tubular element (18) having an outer diameter (D2) and an inner diameter (D1). An inner surface of the tubular element (18) is substantially air impermeable. The second segment further comprises a frangible or irreversibly collapsible flow restrictor (24) disposed in the tubular element (18). When the flow restrictor (24) is in a substantially unbroken or non-collapsed state, the filter unit (14) has a first RTD. When the flow restrictor (24) is broken or collapsed, the filter unit (14) has a second RTD, the second RTD being smaller than the first RTD.

A filtered smoking article includes a smoking body, a filter including a filter member and an air-permeable paper, and having a flavor capsule arranged therein, and a tipping paper. The flavor capsule includes a capsule body, and a colored content liquid containing a flavor component. The air-permeable paper is arranged to be opposed to a region in which the colored content liquid is released when the flavor capsule is crushed, and has an air permeability of 1,000 C.U. to 30,000 C.U. The tipping paper is impermeable to the colored content liquid, and includes at least three transparent parts. Each of the transparent parts is arranged to be opposed to the region in which the colored content liquid is released.

A flow control device (14) for a smoking article (10) is provided. The device comprises first and second selector parts (18, 19) to control flow along a plurality of controllable flow channels.

A lyocell material for a cigarette filter and a method of manufacturing the same are disclose. The lyocell material which is biodegradable and eco-friendly can be manufactured by crimping lyocell multifilaments to obtain a crimped tow.

The invention relates to a cigarette filter. In particular, the present invention relates to a new cigarette filter, in which materials of natural origin are used that have not been applied in this special field before. More particularly, the present invention relates to a cigarette filter, which can be used for absorbing the toxic components of cigarette smoke, and lowering the tissue damage triggered by cigarette smoke on the respiratory organs, the cardiovascular system and the mucosa. Especially the present invention relates to a cigarette filter containing alginate.
