Smoking articles

The present invention relates to a smoking article and a cigarette mouthpiece.

U.S. Patent 2,815.a28 discloses a cigarette assembly in which the passage of smoke is blocked, but the cigarette can be lit. and slowly burns down to give the look and feel of a normal cigarette to convey. Since the cigarette mouthpiece, however, has a solid stopper no air flow can be drawn through the cigarette.

In addition to the desirable properties mentioned above, allowed it is the smoking article according to the present invention, an air stream to be drawn into the smoker's mouth, producing an oral, cigarette-flavored satisfaction without the harmful effects of tar and nicotine is possible.

The present invention provides a cigarette tip made from a hollow one tubular element with a pair of open ends and a smoky one Transverse wall essentially in the middle between the ends, which divides the element into an upper and a sub-area, two of which are cylindrical Stopper made of porous filter material axially abut the open ends and a perforated sleeve coaxially the element and at least a portion of each of the

Surrounds stub and the tubular element in the upper and lower areas . Uielzahl van has openings in the side wall. The mouthpiece is double symmetrically constructed, which simplifies its manufacture, and indeed considerably, as described below.

Furthermore, the invention resides in a smoking article having that described above Mouthpiece and a roll made of flammable, tobacco-like material, which is surrounded by a cover sheet, with the mouthpiece and roller axially abutting one another at one end with the aid of the air-permeable band are joined together that the mouthpiece and part of the roller axially surrounds.

It is also an intermediate product for the manufacture of a cigarette mouthpiece intended·

The novel features and advantages of the present invention follow for those skilled in the art from the following description in conjunction with the accompanying drawing, in which the same reference numerals identify the same parts:

Figure 1 is a broken away view of a smoking article in accordance with the present invention Invention;

Fig. 2 is an end view of the hollow tubular member comprising a Represents feature of the present invention;

3 is a sectional view of the hollow tubular member of FIG Figure 2 along line 3-3;

Figure 4 is a side view of an intermediate product for manufacture a cigarette tip according to the present invention. !

As can be seen in FIG. 2, the mouthpiece 2 consists of a hollow tubular element k made of molded plastic - for example polystyrene - and has two open ^ends: ends 6, 8 and a transverse wall 1o impermeable to smoke in the middle between

the ends that form an upper and a lower region 12 or * \ k . That

Element k, which is shown in detail in FIGS. 2 and 3, has a plurality of openings 16 or slots in the side wall 18 of both the upper and lower regions. The element k has, for example, a length of approximately

409884/0913

1α mm (ο, ^ inch) and a diameter of about 7.6 mm (0.3 inch).

A pair of cylindrical stoppers of neatly rolled, folded crimped paper or other porous filter material are wrapped with unperforated filter wrapping paper 22 and axially butted against the open ends B, 8 of the element by means of a perforated sleeve 2h. The sleeve 2k consists in a suitable manner of cellulose fiber material which is coated on the inside with low-temperature adhesive and glued to the stopper 2o and the element h. The perforation is shown enlarged here for better understanding; typically about 62 holes per square centimeter (ifoo holes per square inch) are provided. The stopper 2o and the Ulickel paper 22 also consist of cellulose fibers.

The stoppers 2o can with flavorings uie bspu). essential oils to be soaked to gnf. simulate the taste of tobacco.

A smoker's article according to the present invention is manufactured by attaching the mouthpiece 2 to a tobacco-like filling 26 which is provided with a wrapping 28 of cellulose fibers, as is common in the lemonade industry. The wrapped filling 26 is shown in abbreviated form in FIG. 1 and is approximately 6.3 to 10 cm (2.5 to 1 hour ) long in a conventional cigarette. The filling can be tobacco or a purified modified cellulose-like material, as disclosed in DT patent 1.goo.if91; this material burns tobacco. If desired, oxidizing agents, humectants, chumectants ¹ ) and flavoring agents can be added to the filling. !

The usual 12.7 to 25, if mm (0.5 ... 1 in.) Long mouthpiece 2 It is made by means of a permeable tape 3o made of lace paper, which is Consists of cellulose fibers (e.g. perforated imitation cork) to which it is wrapped; Infill 26 added. The band 3o is attached to the mouthpiece with a slap 2 and the wrapped filling 26.

To prevent this, the end of the wrapped one that is remote from the mouthpiece is used Fill 26 lit. By sucking on the mouthpiece of the smoker's article

409884/0913

It is drawn through the lace paper 3d and the perforated wrapping ? .K and from there through the slits 16 into the sub-area 14 of the element k (ie the area remote from the burning tip). This air flow passes through the plug 20, where the air takes on the taste of the impregnation before it enters the user's mouth. The user thus retains the feeling of smoking, but remains protected from contact with the combustion products, which are blocked off by the transverse wall 1o.

The different parts that make up the smoking article can be easily assembled with the facilities and procedures derived from the Cigarette making are known; the assembly front is with the conventional ones Machines and processes for the manufacture of tobacco sticks and the like. Compatible.

The double symmetry of the invention ensures a considerably simplified manufacture and simple assembly. Thus, the symmetrical hollow tubular element k is reversible and can be inserted into high speed machines for assembly with the plugs 20 without the need for longitudinal alignment. Furthermore, the overall symmetry of the mouthpiece 2 with its two stoppers 2o allows the mouthpiece to be attached to the wrapped filling 26 without the mouthpiece first having to be specially arranged and aligned. Another manufacturing advantage of double symmetry is as follows.

The present invention also provides an intermediate for manufacture of the cigarette mouthpiece, as shown in Fig. If; this intermediate makes mass production of the mouthpiece much easier.

The intermediate product consists of a multitude of hollow tubular elements if - for example three - and cylindrical plugs 2o, which are axially alternately joined to one another with a perforated sleeve Zk which surrounds the elements and plugs 2o and is fastened to them with a slider, for example .

The stoppers are twice as long as required for the mouthpiece, so that the stoppers can be cut on the lines 32 in the middle, where-

409884/0913

through a large number of symmetrical mouthpieces 2 for the Ueruiendunq in the Production of the smoking article according to the invention results.
