A second tube (3) internally lined with a filtering material (4) is fitted in the first tube to form an annular exhaust passage (5) for residual smoke introduced by blowing through the second tube.

Description

<Desc / Clms Page number 1>

The present invention relates to a device for treatment, in particular by absorption and / or depollution, of the smoke exhaled by a cigarette, cigar, pipe smoker. Or other.

The release of smoke from a burning cigarette or cigar is generally unpleasant for those around a smoker. Furthermore, such fumes contain harmful materials which spread into the environment. We are therefore looking for solutions today to limit this nuisance.

An object of the present invention is therefore to propose a device for treating, in particular by absorption and / or depollution, the fumes exhaled by a cigarette or cigar smoker, the design of which makes it possible on the one hand to at least partially absorb the fumes from the combustion of a cigarette, on the other hand to eliminate from these fumes all or part of the harmful particles contained in

<Desc / Clms Page number 2>

 these fumes.

To this end, the subject of the invention is a device for treating, in particular by absorption and / or depollution, the fumes exhaled by a cigarette, cigar, pipe or other smoker, characterized in that it consists of a first tube closed at one end and the inner walls of which are provided with a filtering material and a second tube internally lined with a filtering material, this second tube being mounted to fit into the first tube and cooperating with the latter of so as to form, at the socket of said tubes, a generally annular passage for exhausting residual fumes introduced into the device by blowing through this second tube.

The invention will be clearly understood on reading the following description of exemplary embodiments, with reference to the single figure which represents a schematic view of a device according to the invention.

As illustrated in the single figure, this device for treating the fumes exhaled by a cigarette, cigar or other tobacco-incorporating article consists of a first tube 1 closed at one end 1A. The outer wall of this first tube 1 is generally a smooth wall while the inner wall of this first tube 1 is coated with a filter material 2 which can be made of any filter and / or absorbent material known to date. This device also comprises a second tube 3 lined internally over all or part of its length with a filtering or absorbent material 4. This second tube 3 is mounted with partial interlocking in the first tube.

The nesting can be of stationary type. However, in a preferred embodiment of the invention, the first and second tubes 1 and 3 are mounted with interlocking

 telescopic. The second tube 3 cooperates with the first tube 1 so as to form, at the socket of said tubes, a passage 5, generally annular, filtering the exhaust of residual fumes, these fumes having been introduced into the device by blowing through the second tube 3. Tube 1 can have a large number of shapes. It can thus be produced in cylindrical form, with circular, hexagonal, octagonal or other director.

As a particular embodiment of the invention, the outer wall of the first tube 1 consists of a sheet produced by textile or paper technology, based on fibers of cellulosic origin, alone or in admixture with polymers of glucose. This sheet can thus consist of a disposable rigid paper, degradable with water or of a plasticized or other paper, washable. The external surface of the element 1 can be made of printable material so as to constitute an information support surface. The filter element 2 can be made from a woven, knitted, non-woven, sewn knitted, quilted sheet, carrying loops or fibers on its surface, the purpose of which is to retain the harmful elements of the smoke, such as nicotine or tar and any additives.

The filter element 2 can thus be produced from textile fibers, such as cellulose or its derivatives, also called viscose or fibranne, but also from any other fiber which can meet this objective of retaining the harmful elements of the smoke.

An exemplary embodiment will consist of a knitted fabric comprising warp and weft threads to form the base of the fabric and loop threads attached to the weft and warp threads. These loop wires rise

<Desc / Clms Page number 4>

 perpendicular to the wall of the tube and will act as a filter.

The outer wall of the tube 1 and the filter element 2 can be assembled by bonding or laminating in the presence of a binder. They can also be assembled by winding, prior to the device manufacturing operation.

The second tube 3 or nested tube is itself made up of a casing wall formed in a manner analogous to the external wall of the first tube 1 while the filtering material 4 can be made similarly to the filtering material 2.

It is noted, due to the path followed by the fumes, that the fumes expelled from the device are in very small quantity and are rid of at least part of their harmful particles.

In a particular embodiment of the invention, the filtering material 4 of the second tube 3 consists of an alignment of tubular sections 4A independent or separable from each other. Each section 4A can thus be detached from an adjacent section or expelled from the tube 3 after use of the device, it being understood that the section 4A, in contact with the mouth of the smoker, is generally the section saturated first with particles such as tar or the like. . This results in the possibility for the smoker to use such a device for several cigarettes. These sections 4A can be of the consistency of current filters (cigarette filter) or of cellulose, of material degradable in water or in any other filtering material. These sections 4A can also be in the form of a woven, knitted or quilted textile sheet.

<Desc / Clms Page number 5>

 or others, which rolls up on itself so as to be foldable and washable. These sections 4A are either disposable or reusable. These sections 4A can be threaded inside the tube 3 so as to be expelled from the tube by a simple push, the section 4A being closest to the mouth being expelled first. There may also be provided, associated with the device, one or more tubular elements for replacing the second tube 3.

In a particular embodiment of the invention, the device is a disposable device, preferably for single use.

To reduce environmental damage, at least part of the tube or tubes 1, 3 is made of a degradable material in contact with water.

It can also be provided to produce at least one of the tubes 1, 3 in a washable material. Preferably, this washable tube will consist of the first tube 1.

The use of such a device is extremely simple. Between each puff of cigarette, the smoker applies his lips around the free end of the second tube 3 and blows the smoke through this second tube 3. The smoke then travels through the entire second tube 3 before escaping naturally through the annular passage 5 formed between first and second tube. During its movement inside the device, the smoke gradually gets rid of its particles retained by the various 4.2 filtering materials. Thus, the fumes expelled from the device are at least partially free of harmful particles.
