SUBSTANCE: tobacco smoke filter has a cylindric cover containing a spiral element with diameter approximately equal to the inner diameter of the cover as well as filtering means placed between the spiral element and the cover. The spiral element contacts the cover to the its inner diameter and is made by means of sideward compressing with the ability to maintain the contact after the compression. Filter production requires the preparation of the cylindric spiral having the inner space inside the spiral volute and outer edge making a cylindrical form. In the specified inner space filter means are located along with wrapped outer edge of the filled spiral cover. Spiral element is used sidewards thus providing its contact with the cover which is preserved after the spiral element copression.

EFFECT: this filter provides the increased contact time with the filtering material and expanded space of the filtering material contact surface.

SUBSTANCE: invention is related to an improved smoking product filter, in particular, to a cigarette filter. The filter includes the first section containing a smoke-impermeable material with a smoke flow duct longitudinally arranged therethrough, the second section positioned at an interval relative to the first section, the gap providing for smoke passage from the first section to the second one without dispersion of a greater part of its particles prior to reaching second section material. The second section is axially aligned with the first one. The second section contains a core segment enclosed by the circumferential space segment and ventilation holes arranged in the second section or in the interval. One of the sections of the core and the circumferential space contains a filtering material with a high differential pressure. The other of the above sections contains a material with a lower differential pressure. The smoke flow duct is longitudinally aligned with the circumferential space segment or the core segment containing the material with a high differential pressure. In accordance with another version the filter includes the first section containing a smoke-impermeable material with a smoke flow duct longitudinally arranged therethrough, the second section positioned at an interval relative to the first section, the gap providing for smoke passage from the first section to the second one without dispersion of a greater part of its particles prior to reaching second section material. The second section is axially aligned with the first one. The second section has a mouthpiece end on the interval side. The filter has ventilation holes arranged in the second section or in the interval and a smoke-impermeable closure insert connected to the second section end on the interval side. The smoke flow duct is matched to the closure insert.

SUBSTANCE: smoking device contains a receiving container holding or capable to hold combustible products, mainly - tobacco. Connected to the receiving container is a filtering element having at least one fragile capsule containing a core and a coating. The capsule initial crushing strength is from 4.9 to 24.5 N. After smoking test the capsule preserves crushing strength from 4.9 to 24.5 N. Before destruction the size of its deformation is less than two thirds of its diametre. The coating contains at least one hydrocolloids represented by gellan gum, agar, alginates, carrageenans, pectins, gum arabic, Ghatti gum, pullulan, mannan gum or modified starch taken singly or in a mixture or in combination with gelatine. The quantity of hydrocolloid in the coating is 1.5 - 95 wt %, predominantly - 4 - 75 wt % and more preferably - 20 - 50 wt % of the coating total weight. The method of such a capsule production involves coextrusion of hydrophilous outer liquid phase and lipophilic inner liquid phase; solidification and/or condensation of the coating surface by way of the capsule maintenance under cold conditions; the capsule final rinsing with an organic solvent; the capsules drying and additionally covering the capsules with at least one moister protecting layer.

EFFECT: invention allows to produce a capsule preserving its ability for destruction even after a moisture impact.

SUBSTANCE: flavouring particle comprises a carrier particle, glucan film deposited on the carrier particle, and a flavouring. Flavouring agent is retained by the flavouring particle so that emanation of flavour from aromatic substance is inhibited by the glucan film. However, the flavour is released with glucan film which is at least partially destroyed when glucan film is in contact with the main smoke stream. Cigarette filter may include this flavouring particle.

EFFECT: creation of a cigarette filter with a flavouring particle which prevents evaporation and migration of aromatic substance in non-smoking of cigarettes and provide with a stable sense of taste and aroma during the stages of smoking without making external effort.
