Embodiment Construction

[0023] The present invention provides a filter for a smoking article comprising a carrier comprising a liquid capable of improving the breakdown, dispersion and / or degradation of the smoking article. The carrier is preferably resistant to manipulation during use of the smoking article and will be actuated to release the liquid contents into the filter when the smoking article is handled. Disintegration and degradation of the filter may occur directly, for example, by dissolution or degradation of one or more components of the filter (eg filter material) in the liquid. Alternatively, the improvement in degradation may be achieved indirectly, for example due to increased environmental exposure due to accelerated decomposition of the filter under the action of liquids.

[0024] figure 1 A smoking article 1 comprising a filter 2 is shown. The filter 2 comprises two sections of a generally cylindrical filter plug 3 separated by a cavity 6 . The filter plug and cavity are wrapped...

Abstract

A filter (2) for a smoking article (1) is provided by the present invention, the filter comprising a vehicle containing a liquid capable of enhancing the disintegration and / or dispersibility of the smoking article. A method of enhancing the disintegration and / or degradation of a smoking article is also provided, wherein the smoking article comprises a vehicle containing a liquid capable of enhancing the disintegration and / or degradation of the smoking article.

Description

technical field [0001] The present invention relates to improving the disintegration and / or degradation of used smoking articles, and in particular but not exclusively to improving the disintegration and / or degradation of filters for such smoking articles. Background technique [0002] A problem with currently available tobacco smoke filters, especially cigarette filters, is that they can be difficult to dispose of after use. [0003] During smoking, most of the tobacco rod and the wrapper surrounding the tobacco rod are converted into gases and ash during incineration. The remaining components of a used smoking article include a small portion of ash, a portion of the original tobacco rod and wrapper, and a filter consisting of a filter plug, plug wrap and tipping paper surrounding the tobacco rod and filter wrap. There is also an adhesive that holds these parts together. Used smoking articles typically disintegrate completely into their individual components within a rela...
