Definitions

• the present invention relates to a smoker's article intended to reduce the amount of smoke emitted by a cigarette, in particular to reduce the amount of so-called side stream smoke.
• This last smoke is the smoke emitted by the burning end of the cigarette. It is particularly visible between two aspirations of the smoker, for example when the cigarette rests on an ashtray.
• the sleeve is in the form of a segment of pipe, preferably rigid, with an internal diameter approximately equal to the diameter of a cigarette.
• This sleeve is made of metal, plastic or is in the form of a thin layer of rolled up inorganic paper.
• This system has certain disadvantages, for example the difficulty of a use which must become instinctive, the traces of condensation which appear on the external and internal walls, fouling and an alteration in taste due to the material used.
• the present invention consists in making appreciable improvements to this type of device by facilitating its handling by the smoker who uses it and by facilitating daily and hygienic use.
• a device comprising at least one part covering or approaching the burning end of the cigarette (distal part) and a separate gripping part which is used for handling (proximal part).
• the part covering or approaching the burning end of the cigarette is made of a material used for the traditional pipe stove, more particularly briar wood or sea foam.
• the above-mentioned parts are preferably presented in the form of longitudinal segments distinc r secured by friction, screwing or gluing.
• the article consequently comprises a grip part made of a more stable and more economical material, for example another wood or a plastic.
• This aspect of the invention allows industrial manufacturing.
• the sleeve works as a 1 "controlled extinguisher. It can be pushed towards the hot end ⁇ * brought to a more proximal position, generally with the fingers of the free hand of the smoker.
• the manipulation can also, advantageously, be done with the fingers of the hand holding the cigarette, for example with the thumb to push the cigarette on the one hand and the thumb and ring finger to remove the cigarette. You can still, to slide a very light sleeve, use only the index finger.
• the displacement of the sleeve along the cigarette can also be done by holding the cigarette between the lips, the index and middle fingers grasping the article as one grasps a cigarette in a conventional manner and making it slide.
• the user can easily acquire a certain dexterity to move the sleeve along the cigarette and thus control the emission of secondhand smoke. If at beginning of accidental extinctions can occur, very quickly this dexterity becomes effective and natural and even instinctive.
• the burning time of cigarettes is generally increased.
• the presence of the latter prevents the cigarette from being smoked to the filter end, which constitutes an advantage insofar as it is this last part which is recognized as being the most harmful (tar, nicotine, heat). If the user wishes, the sleeve can be removed at any time and the rest of the cigarette smoked as usual.
• the invention can also provide numerous advantages due to slower combustion. Furthermore, the article allows the extinction and re-lighting of a cigarette at will without the need for an ashtray, and without substantial alteration of taste, unsightly crushing of the end of the cigarette, or even emission of smoke. to extinction.
• slowing down of combustion can be desired in environments where it is too fast, e.g. in the open air and in the presence of wind.
• the article according to the invention can be placed horizontally on a table with the cigarette lit there WO 96/41546 -. ----- _
• the sleeve is a short sleeve of a non-flammable material at the temperature of the burning end of the cigarette.
• the sleeve comprises at least two functionally different parts, namely a proximal gripping part and a distal part forming a combustion chamber with controlled ventilation.
• the device according to the invention will be made of wood, more preferably a wood which can be used to make traditional pipes, in particular pipe stoves.
• a wood which can be used to make traditional pipes, in particular pipe stoves.
• it will be heather or boxwood.
• woods are a particularly advantageous material, inter alia because the taste of the smoke sucked is not or only slightly altered.
• the sleeves can be formed by turning.
• more accessible wood eg so-called food wood such as beech
• economic materials known for making pipes corn.
• Heat stability in particular for high-end products, is important so as to allow constant friction between the cigarette and the device according to the invention. If the sleeve diameter increases too large under the effect of heat, it may slip and fall out of the body of the cigarette.
• the sleeve is made of at least two separable parts.
• the two parts can be made of different materials, for example wood of different species.
• the proximal part, for gripping can then be designed as a more worked and decorative element, and the distal part adapting by friction would be made of wood and, according to a variant, replaceable like a cartridge after smoking a certain number of cigarettes.
• these two parts can therefore be made of different materials, for example heather for the distal part and plastic for the proximal part.
• the length of the sleeve is preferably such that the two fingers holding the cigarette must be able to easily grasp the sleeve at its proximal part, the distal part being alone intended to cover or approach the hot end and being generally substantially hotter.
• the proximal part advantageously comprises at least one hollow or an annular groove intended to receive the fingers of the user holding the sleeve with the cigarette inserted therein.
• the total length will typically be between 2 and 5 cm, preferably 2.8 to 4.0 cm. A length of 3.2 cm has proved satisfactory for a large number of different models.
• the configuration of the proximal part of the sleeve so as to leave ventilation under this part. It is thus possible to provide orifices or slots which allow the paper of the cigarette to be directly in contact with the outside. This feature prevents unwanted condensation inside the sleeve.
• the percentage of the ventilated area can exceed 40%.
• the inner face of this proximal part may also have longitudinal grooves which alone bear by friction on the body of the cigarette and thus make it possible to further aerate the paper.
• the distal part of the device can include fins, longitudinal or transverse, which dissipate the heat transmitted by the hot end. This avoids involuntary burns by contact of a finger on this part which, depending on the material used, can actually be very hot.
• the distal and proximal part however form a single wooden body comprising several integrated segments (gripping segment - combustion chamber segment).
• the end of the distal part however includes an inner annular housing (damage) in which is fixed by friction a ring of a material better adapted and more resistant to heat, in particular in heather, sea foam or earth cooked.
• the wall of the ring advantageously has a thickness greater than 1 mm (generally from 0.5 mm to 4.5 mm). The ring can be easily replaced or simply removed and returned, returned to the annular housing to thereby provide a new annular focus area.
• the plug is a cleaning plug having an abrasive wall capable of removing any deposit from the interior wall of the tube at its distal end.
• the plug can advantageously be adapted to also cover part of the external wall of the distal part of the sleeve.
• the plug is screwed onto a thread present at the - 10 -
• the sleeve according to the invention is presented in a container, for example in the form of a case, preferably rigid.
• This case includes two complementary parts, integral or adaptable by friction.
• a plug, abrasive plug or abrasive rod element can be attached to the case, which thus constitutes a kit.
• This kit can include several sleeves or parts of sleeves according to the invention.
• the user can have several articles according to the invention in order to be able to smoke in circumstances and with slightly different tastes, and thus amplify the playful aspect of the invention. We can thus let a sleeve cool or "rest", using another copy. The practice will be quite close to that of pipe smokers.
• a guard can be provided at the end of the sleeve, or preferably at the end of the aforementioned proximal part of the sleeve in the form of an annular bead extending more or less perpendicular to the axis of the sleeve and surrounding it. This element, by obstructing, allows the residual smoke that is produced, to less contaminate the smoker's fingers.
• An ergonomic shape for the grip between the fingers of the user can be advantageously adopted by providing, in combination or not with the aforementioned bead, a second bead at the proximal end, the fingers thus fitting into a well-formed annular groove .
• the proximal end of the article may have an opening with a beveled edge or a flared opening to facilitate the introduction of the cigarette into the sleeve, generally before lighting the cigarette.
• the device proposed consists of three segments:
• a proximal part intended for gripping by the fingers of the user, which can be separable.
• the wall is preferably largely perforated.
• the diameter of the latter is preferably very slightly greater than the diameter of a cigarette, thus allowing the underlying cigarette paper to breathe.
• This part is preferably light, fireproof, very airy and stable. a shorter, annular seal portion with a diameter such that the friction of the cigarette is greater there than that of the distal portion and possibly of the proximal portion.
• This part of sealing pe corresponds to a segment of 0.2 to 0.5 cm.
• the * sealing ie prevents the passage of air and / or smoke, along the outer wall of the cigarette, between the proximal part and the distal part. This feature prevents, among other things, any soiling of the proximal part, eg by condensation of smoke, as well as any emission of smoke from an air supply coming from the proximal part, along the paper of the cigarette.
