A smoking article filter includes a recess to receive a filter insert unit. The filter insert unit is secured to the filter once inserted. The filter and the filter insert unit may include additives such as flavourants, colourants or sorbents.

Smoking article filter and insertable filter unit therefor

A smoking article filter () comprises a recess () to receive a filter insert unit (). The filter insert unit () is secured to the filter () once inserted. The filter () and the filter insert unit () may comprise additives such as flavourants, colourants or sorbents.

An inhalation device to hold an inhalant-generating component to generate an inhalant to be drawn through the device and inhaled by a user. The device has a body () having a first open end () configured to receive an inhalant-generating component and, a second open end () in fluid communication with the first end through which a user may draw inhalant from the inhalant-generating component. The body is configured to receive a flavour delivery component () having an organoleptic material to selectively allow or prevent addition of an organoleptic additive into an inhalant stream drawn through the device. The device includes a ventilation control mechanism () configured to selectively allow different amounts of ambient air into the body to mix with and dilute the inhalant stream as it is drawn through the device in use.

Inhalation device and inhalant apparatus

A filter for a cigarette comprises a porous fitter rod and a material sheet wrapped around the filter rod and a cellulose acetate thread formed from substantially uncrimped cellulose acetate filaments. The cellulose acetate thread is positioned within the filter rod and extends along the central axis of the filter rod.

Filter

The present invention relates to improvements in filters for use in smoking articles such as cigarettes, cigars and cigarillos. The improvements, particularly but not exclusively, relate to filter capabilities and to the manufacture of such filters. In one example, a filter for a smoking article comprises a first fibrous filter material having an average fiber denier in the range 7 to 9 and a second fibrous filter material having an average fiber denier of below 7. The application also describes a filter for a smoking article comprising various other filter arrangements including absorbent and/or adsorbent materials.

Smoking article filters

The present invention relates to improvements in filters for use in smoking articles such as cigarettes, cigars and cigarillos. The improvements, particularly but not exclusively, relate to filter capabilities and to the manufacture of such filters. In one example, a filter for a smoking article comprises randomly oriented discrete short length fibres of absorbent having adsorbent particles dispersed therein. The invention also provides a filter for a smoking article comprising various other filter arrangements including absorbent and/or adsorbent materials.

The present invention relates to the inclusion of additives in a filter element comprising a non-woven sheet material or paper as the filter material to increase the selective removal of semi-volatile compounds and to improve the taste characteristics of the smoke drawn through the filter element. The increased selective removal of semi-volatile compounds from the smoke being drawn through the filter element is provided by polyethylene glycol. TEC and/or triacetin are additives which have been found to improve the taste characteristics of smoke drawn through the filter element.

Sheet filter materials with additives

A filter for a cigarette comprises a porous material sheet wrapped around the filter rod and a cellulose acetate thread formed tram substantially uncrimped cellulose acetate filaments. The cellulose acetate thread is positioned within the filter rod and extends along the central axis of the filter rod.

A smoking article, and a method and apparatus for producing a smoking article, in which a web material containing an adsorbent material such as activated carbon and a stabilized flavorant such as menthol is positioned adjacent an interior surface of a cigarette wrapper to deliver flavor to a smoker with minimal/insignificant migration of flavor to other parts of the smoking article or packaging. The web material may be a section that extends over only a portion of the smoking article to deliver flavor to a smoker at a specific point during smoking and if positioned at the mouth end of a smoking article will be able to deliver a flavor sensation in the final puff(s).

Smoking article and apparatus and process for manufacturing a smoking article

A filter for a cigarette comprises a porous filter rod () a material sheet () wrapped around the filter rod and a cellulose acetate thread () formed from substantially uncrimped cellulose acetate filaments. The cellulose acetate thread is positioned within the filter rod and extends along the central axis of the filter rod.

Packaging for smoking articles with sealed enclosure

Cigarette pack

A lightweight cigarette filter including a filter element containing filter material having a total Denier of less than 35,000 or a bulk density of less than 0.12 gcm.sup.-3 in which part of the volume of the filter is occupied by a space filler impervious to smoke flow therethrough and the bulk density of which is less than the bulk density of the equivalent amount of filter material which it replaces.
