Problems solved by technology

[0005] Another limitation of the use of paper filters is that they have lower retention than cellulose acetate for toxic phenolic compounds – such as phenol, cresol, catechol and resorcinol – present in the volatile and semi-volatile phases of cigarette smoke filters; this results in a higher relative yield of phenolic compounds from cigarettes with paper filters

Embodiment 1

[0041] Sample paper filters were fabricated from cylindrical rods (15mm long, 24.50mm circumference) of paper formed from a non-aperture porous web of 100% wood pulp fibers according to the method set forth in GB2075328A.

[0042] Paper was formed from fibers 2.5 to 6 mm long and had a finished substance (before corrugation) of 15 to 35 g / m2 on an inclined wire paper machine (by the method set forth in GB2075328). The first in the form of celery seed essential oil [unresolved mixture of compounds including flavor additives sydanrolactone and 3-butylphthalide] will be included by conventional methods of applying flavorings to paper (such as printing wheels, etc.) The flavorant solution of the flavoring additive is applied to the continuous feed of finished paper (before corrugation). Additional additives in the form of polyethylene glycol were also applied to the paper by methods well known in the art. The longitudinally fed finished paper web, to which the additives have been...

Embodiment 2

[0046] Taste testing (using methods well known in the art) demonstrated that the deleterious "papery" impact on cigarette taste was reduced or even eliminated by inclusion of a flavor-enhancing additive according to an aspect of the present invention.

[0047] Sensory testing by a panel of trained professional smokers. Samples of commercial cigarettes of leading brands were purchased in batches from retail stores. The brands have one-piece cellulose acetate ("monoacetate") filters and these were supplied as "control" cigarettes ("C") for the following procedures.

[0048] Filters were removed from the first set of cigarettes and replaced with machine-made paper filters of equivalent tar retention. These filters are hereinafter referred to as unmodified paper filter cigarettes ("P").

[0049] Filters were also removed from the second group of cigarettes and replaced with machine-made paper filters of equivalent tar retention (as in group P). A metered amount of a flavor solu...

Embodiment 3

[0053] Testing smoking articles that heat rather than burn tobacco. A metered amount of a flavoring solution comprising a flavoring additive, for example in the form of celery seed essential oil, is injected into a cellulose acetate filter of a heat-not-burn-tobacco smoking article. The smoker panel noted that this resulted in a superior organoleptic profile compared to the unmodified version of the same product.

Abstract

A tobacco smoke filter or filter element comprising: a tobacco smoke filtering material including paper; and a flavour enhancing additive.

Description

[0001] This application is a divisional application of the parent application with application number 201080023039.5. The filing date of the parent case is May 25, 2010; the invention name is "tobacco smoke filter". technical field [0002] The present invention relates to tobacco smoke filters (for example for cigarettes) and their manufacture. Background technique [0003] Worldwide, cellulose acetate is the main material used in tobacco smoke filters. It is also known to use paper as filter material in filters, for example for cigarettes; paper offers advantages over cellulose acetate in terms of improved biodegradability, higher filtration efficiency at a given pressure drop and lower material cost. Many advantages. Despite these advantages, the applications of paper filters are small and generally limited to niche uses. The main reason why paper filters have not attracted general market interest is that they have a detrimental effect on the taste of cigarettes. ...
