Definitions
- the invention relates to a mouthpiece for a cigarette or the like.
- a ventilated, filterless cigarette consisting essentially of a cylindrical sleeve to be fastened to an end face of the tobacco rod covered with paper and having an outer diameter substantially corresponding to the wrapped tobacco rod, in which a ribbed support body is arranged, the ribs of which extend essentially in the longitudinal direction of the sleeve and are each supported on their outer edge on the inner wall of the sleeve.
- the mouthpiece for a cigarette “or the like.” is determined and suitable, it is to be expressed by this that it can in principle also be used, for example, for a cigarillo, although it is primarily intended for a cigarette, in particular for a ventilated cigarette not provided with a classic filter , the smoke flow of which is thus diluted by air drawn in from the environment when smoking, although the mouthpiece is in principle also suitable for non-ventilated cigarettes, and also for cigarettes which are provided with a conventional filter (section).
- filterless cigarettes are provided with a mouthpiece in various embodiments of cigarettes in order to prevent tobacco particles from getting into the smoker's mouth from the mouth end of the tobacco rod when smoking.
- a mouthpiece for example, from DE-AS 16 32 222 an existing molded plastic, provided with a covering, one-piece mouthpiece is known, which consists of a hollow, cylindrical sleeve and three integrally formed with the sleeve, radially inwardly extending ribs are integrally connected at their inner edge to a tubular, central chamber which connects the tobacco-side end of the mouthpiece to the mouth-side end of the mouthpiece, wherein a filter insert can optionally be provided between the sleeve provided with ribs forming a supporting body and the tobacco rod.
- the connection of the mouthpiece to the tobacco rod wrapped with cigarette paper takes place by means of a wrapping, also referred to below as covering paper, which extends from the mouth-side end of the sleeve extends over the sleeve and a section of the wrapped tobacco rod and is connected to both (for example by gluing), the covering paper being provided with a perforated opening in a design with a filter insert, through which air sucked in from outside enters the filter when it is smoking and there smoke flowing from the tobacco rod to the smoker's mouth, so that the channels formed by the ribs and the inside of the sleeve lead to air thinned smoke to the smoker's mouth, while practically only undiluted smoke flows through the central, tubular chamber of the mouthpiece to the smoker's mouth, since the air sucked in through the perforation openings does not reach the middle section of the filter insert due to the existing resistances, especially since it is still provided that the actual filter material of the filter is covered with a cover made of perforated or porous paper
- This known mouthpiece is extremely disadvantageous because it consists of plastic, that is, a non-decomposable material and is accordingly correspondingly hostile to the environment, since the mouthpieces of discarded, smoked cigarette butts accumulate in the environment.
- Another disadvantage of the known mouthpiece in a filterless version is that the smoker has a clear view of the mouth end of the tobacco rod when looking at the mouth end of the cigarette, which is a dark hole offset inward from the mouth end of the sleeve offers, from which tobacco smoke oozes, which many smokers find mostly unpleasant for aesthetic reasons.
- a mouthpiece consisting only of a cardboard sleeve which surrounds the wrapped tobacco rod at its mouth end via a section and is connected to it, and which is between the mouth end of the tobacco rod and the mouth end of the mouthpiece Perforation openings are provided, through which air is sucked in from outside during smoking in order to dilute the tobacco smoke drawn in from the tobacco rod.
- this known mouthpiece is more environmentally friendly than the mouthpiece previously discussed, because it consists of cardboard and thus of rotting paper material, it also has the other disadvantages mentioned above with reference to the mouthpiece according to DE-AS 16 32 222.
- a mouthpiece which consists of a sleeve provided with perforation openings and a ribbed support body made of plastic (Fig. 1-4), the mouth end portion of the mouthpiece according to the filter of DE-AS 16 32 222 is formed, and the tobacco-side end portion of the mouth piece within the sleeve has a further cylindrical sleeve section which abuts the inside of the outer sleeve and with a conical intermediate section merges into the central tubular tubular smoke channel, which is considerably smaller in diameter, so that the smoke sucked in from the tobacco rod from that present at the tobacco-side end of the mouthpiece inner sleeve and passed over the conical intermediate section into the mouth-side end section of the tubular, central chamber supported by the ribs and having a considerably smaller diameter and from there into the smoker's mouth.
- the air sucked in through the perforation openings flows into the smoker's mouth when smoking through the outer chambers formed by the ribs and the
- This well-known mouthpiece is already made of plastic due to its complicated construction and is accordingly also environmentally harmful. Here too there is no optimal smoke guidance and the smoke flows separately from the dilution air into the smoker's mouth.
- US Pat. No. 3,789,855 also discloses a further embodiment (FIG. 8) in which the support body of the mouthpiece can consist of corrugated cardboard.
- the support body of the mouthpiece can consist of corrugated cardboard.
- this mouthpiece there is also no optimal smoke guidance and the suctioned ventilation air reaches the smoker's mouth separately from the suctioned smoke, so that this known mouthpiece also resp Manufacturing is extremely expensive.
- this known mouthpiece is also integrally made of plastic and is correspondingly hostile to the environment, here, as with the mouthpiece according to DE-AS 16 32 222, there is a clear view from the mouth end of the mouth end of the tobacco rod with those described above Disadvantages are given and the smoke guidance is not optimal, although this known mouthpiece is more advantageous than the mouthpieces known from DE-AS 16 32 222 and US Pat. No. 3,789,855, because - just like the mouthpiece according to GB-PS 955 639 - feeds only thinned smoke to the smoker's mouth.
- the mouthpieces discussed above differ fundamentally from mouthpieces such as are described, for example, in DE-AS 16 57 261, in which, in the case of a ventilated version of a cigarette, the smoke flow is supplied to the smoker's mouth separately from the ventilation air sucked in during smoking, which is the case with the mouthpiece according to DE-AS 16 57 261 characterized in that the sleeve is provided on its outside with grooves and surrounded by a further sleeve which is connected to the environment, for example through perforation holes, so that the air sucked in from the outside through the so formed grooves flows into the smokers mouth, while the undiluted smoke flows into the smokers mouth through the hollow interior formed by the sleeve space is supplied.
- Such a separate smoke and air duct which leads to a thinning of the smoke only in the smoker's mouth, is however not to be regarded as advantageous.
- a filter generally an acetate filter
- ventilation the addition of air to the smoke
- the different variants each have advantages and disadvantages - not only with regard to the manufacturing costs - and enjoy different acceptance among smokers.
- the present invention has for its object a or the like for all configurations of .cigarettes. to provide a suitable, inexpensive to produce generic mouthpiece, in particular for ventilated, filterless cigarettes, which is to be produced from an inexpensive, relatively easy-to-process, thin, quickly decomposable material and yet has the strength required for smoking and, if applicable, for making ventilation openings, and above that addition, the possibility should nevertheless be created that the smoker looks at the mouth end the mouthpiece cannot see the mouth end of the tobacco rod and it should be ensured that, in the case of training for a ventilated cigarette, the smoke flowing from the tobacco rod can practically completely mix intimately with the sucked-in air before entering the smoker's mouth and the ribs can not only exert a certain filtering effect on the smoke-air flow, but can also impart a flow behavior which leads to a largely stable outlet flow, so that the smoker can direct the flow entering the mouth into particularly taste-sensitive zones.
- a ventilated design of the mouthpiece is intended to ensure that the smoker receives a smoke-air mixture when smoking, which has nicotine and condensate values that actually correspond to the values determined on smoking machines and are not changed due to the smoking habits of the smoker, as can be the case with mouthpieces with peripheral air flow separated from the smoke.
- the free flow cross section of the mouthpiece predetermined by the sleeve should be narrowed as little as possible by the support body.
- the ribs each consist of at least two layers or sections or layers of a relatively thin, foldable, web-shaped material, at least one layer of one rib being connected to at least one layer of another rib, so that this results in a correspondingly good internal support of the ribs.
- a layer of a rib is connected to a layer of an adjacent rib, since such a Can be configured particularly easily, in particular when at least the interconnected layers of two ribs are integrally formed, as is preferably provided, and / or when, in a preferred embodiment of the invention, the layers of all ribs are integrally formed.
- the support body is formed from a leporello-like folded strip, which consists of a relatively thin, web-shaped, rotten material - preferably made of paper - with a pair of adjacent folded sections of the strip forming a rib and the sleeve can also be made of a decomposable material in a manner known per se in order to arrive at an overall decomposable mouthpiece. It is usually Particularly useful if the support body and the sleeve are made of the same material, preferably made of paper.
- the layers of a rib preferably abut one another and, in a preferred embodiment, are connected to one another at least at one section, which is expediently made by gluing or the like. can be done.
- the support body of which is formed from a leporello-like strip, this means that the two mutually facing sides of a pair of folding sections forming a rib are in contact with one another issue.
- the ribs of the support body are each connected on their outer edge (at least partially) to the inner wall of the sleeve, or the like in a paper configuration. expediently done by gluing or gluing.
- the ribs preferably run in a manner known per se, i.w. radial to the sleeve and can extend over their entire length, preferably extending in their other direction up to the longitudinal axis of the sleeve.
- the ribs are in each case twisted or twisted on at least one longitudinal section, preferably over the entire length of the support body, in such a way that their free outer edge extends helically to the central axis of the sleeve.
- Such a twisting of the support body or its ribs leads to various advantages.
- each line of the sleeve running parallel to the central axis is supported at least at one point by a rib, so that overall a considerably better strength than a non-twisted version of the mouthpiece.
- a mouthpiece with a support body twisted like this gives the smoke flow - in the case of a ventilated cigarette the mixed smoke-air flow - gives a certain twist around the central axis of the mouthpiece or the cigarette, which leads to a certain stabilization of the smoke flow, so that the smoker can direct these particularly sensitive areas of the mouth.
- the sleeve either consists of an air-permeable material or is provided with perforation openings at a distance from its mouth-side end and at a distance from the end of the tobacco rod, which are arranged on an annular path can be provided in one or more rows.
- the sleeve in a manner known per se with the covering of the tobacco rod connected by a covering paper, as this is preferably provided, which is glued on the one hand to the sleeve and on the other hand to the sheathing of the tobacco rod, so the usually gas-impermeable covering paper or the like is at least at one point by perforation.
- air-permeable and this air-permeable point is arranged in the region of an air-permeable point of the sleeve, so that when smoking air can enter from outside through the covering paper and the sleeve into their hollow interior - except for the support body - and mix there with the smoke.
- This mixing is very intimate in the mouthpiece according to the invention, since the air sucked in from the outside enters the interior of the shell essentially radially through the small openings of the covering paper and the shell when a vacuum is applied to the mouth-side end of the mouthpiece, and since the speed of the smoke entering the mouthpiece in the longitudinal direction is relatively slow. It is also not significantly increased because the cross-sectional narrowing of the sleeve is extremely small due to the thin ribs. Moreover, in the case of a mouthpiece with a twisted support body, its twisting still contributes to an intimate mixture of smoke and air, so that ultimately a largely uniformly mixed flow of smoke and air emerges from the mouthpiece and reaches the smoker's mouth.
- the mouthpiece 2 consists of a cylindrical sleeve 3 made of 30 g paper and a support body designated overall by 4, which consists of the same material as the sleeve 3.
- the mouthpiece 2 is attached to the front of the tobacco rod 6 wrapped with conventional cigarette paper 5 by means of a covering paper 7, namely by two ring-shaped glue points 8. It can be seen that the outer diameter of the mouthpiece is equal to the outer diameter of the wrapped tobacco rod 6.
- the support body 4 is shown with (only) four ribs 9 to illustrate its basic design, although more than four ribs 9 are preferably provided (see preferred exemplary embodiment according to FIG. 18), as will be explained further below.
- the ribs 9 run parallel to the central axis 10, extend over the entire length L of the sleeve 3 or the mouthpiece 2 and each extend radially from the inner wall 11 of the sleeve 3 to the central axis 10, two ribs 9 each having a pitch angle ⁇ of Include 90 °.
- the ribs 9 are therefore each supported on the inner wall 11 of the sleeve 3 and are glued there. Due to their (double-layered) construction from a relatively thin paper, they hardly narrow the free flow cross section of the sleeve 3 and nevertheless considerably increase the strength of the mouthpiece compared to a ribless design.
- the ribs 9 each consist of two layers F 1 , F 2 or F 3 , F 4 etc. made of paper, as will be explained in more detail below, the two layers forming a rib 9 being glued together and one each Layer (eg F 2 ) of a rib 9 is connected to a layer (F 3 ) of an adjacent rib 9.
- This connection is established in that all layers of all the ribs are integrally formed, that is to say are formed from a coherent paper section 12, as is explained in principle below with reference to FIGS. 14 to 17.
- the section 12 ′ shows a plan view of a (paper) section 12 ′ which is flat in the initial state shown, for forming support bodies 4, more precisely first of all a support body strand.
- the section 12 ' has a width b which is equal to the product of the double rib height r of a rib 9 and the number of ribs.
- the strip-shaped section 12 ' is folded like a leporello on parallel fold lines f 1 , f 2 etc., as can be seen in FIG. 15, so that between the longitudinal edge f 0 and the adjacent fold line f 1 or respectively between adjacent fold lines f 1 , f2; f 2 , F 3 etc.
- each fold sections are formed which run in the longitudinal direction of the strip-shaped paper section 12 '.
- a section line 15 running parallel to the front edge 21 is shown in FIG. 14 with a dashed line, and a further section line 15, etc., which in turn divides the strip-shaped section 12 'into strip-shaped sections 12 at a distance L. which later each form a support body 4.
- a support body 4 in mass production expediently does not take place in each case from a strip-shaped section 12, but the web-like material (paper) forming the support body is removed from a bobbin forming a material stock by means of a corresponding device in the direction of arrow 20 peeled and folded in the longitudinal direction, as described above.
- a rib 9 consisting of two paper layers, one layer (for example F 2 ) with a layer (F 3 ) of an adjacent rib 9 by integrally forming the folded sections or layers (F 2 , F 3 ; F 4 , F 5 ) etc. are connected at their foot line.
- a dashed line in Fig. 16 shown portion 13 of the folded portion 9 connects the F 8, with the fold portion F 1 of the adjacent rib (for example by gluing).
- mouthpiece sections of the final length L could also be immediately separated from the sleeve strand created if this is desired.
- the covering paper 7 connecting the sleeve 3 with the tobacco rod 6 wrapped with cigarette paper 5 is provided with perforation openings 16 and the sleeve 3 is provided with perforation openings 18 aligned therewith, so that when smoking according to the arrow 18 (see FIG. 1 ) Air can enter the mouthpiece 2 from the outside through the openings 16, 17 and mix there with the tobacco smoke which, according to the arrows 19, enters the mouthpiece 2 from the tobacco rod 6 essentially parallel to the central axis 10.
- radially rib 9 running upwards only runs vertically upwards at its mouth-side edge and is pivoted along its length by the twisting in such a way that its outer edge 14 extends essentially helically to the central axis 10, so that the radially running edge of this rib facing the tobacco rod 9 runs horizontally.
- Such a twisting generally takes place before the Support body 4 or support body strand is surrounded with sleeve material 3, however, can optionally also take place here and can be realized in manufacturing technology without problems by appropriate conditioning of the paper material forming the support body 4.
- Such a twisting first of all has the effect that the smoker can no longer look at the tobacco-side end of the tobacco rod 6 with a top view of the mouthpiece 2 on the mouth side, since this is covered by the twisted ribs. Furthermore, such a twisting, which is preferably at least as large as the preferably the same pitch angle ⁇ between two adjacent ribs, means that each line of the sleeve 3 running parallel to the central axis 10 is radially supported at at least one point, which increases the strength of the mouthpiece. Finally, such a twisting also has an advantageous effect on the smoking properties of a cigarette equipped with such a mouthpiece.
- the ribs 9 can exert a certain filter effect, and in particular if they consist of a gas-permeable paper.
- the twisted ribs 9 give the smoke flowing out of the tobacco rod 6 and the ventilation air flowing in through the openings 16, 18 a certain swirl about the central axis 10, whereby there is an intimate mixing of the smoke with the air and at the outlet end of the mouthpiece 2 there is an intimately mixed flow of smoke and air which, if desired, the smoker can direct to particularly taste-sensitive areas in the mouth in order to obtain a particularly intense smoking experience.
- the support body 4 in the illustrations according to FIGS. 1 to 17 is provided (only) with four ribs 9 for reasons of illustration, but that a preferred embodiment according to FIG. 18 consists in the support body 4 having ten ribs 9 is provided, each having the same pitch angle OC. of .36 ° to an adjacent rib 9 in order to give the mouthpiece 2 the strength required for smoking and making the perforation openings 18 with a relatively thin starting material made of, for example, 30 g paper, the ribs 9 of the support body 4 according to FIG 18 are preferably twisted by an angle of (at least) 36 ° in order to obtain the advantages described above. An apprenticeship with ten.
- Ribs 9 is also advantageous over a design with only four ribs because a twist angle of approximately 36 ° for a support body 4 can be achieved more easily with the material used than a larger angle of e.g. 90 °. Nevertheless, the support body 4 does not significantly narrow the flow cross section of the sleeve 3 even in an embodiment with ten ribs 9, so that the smoke flow entering the mouthpiece 2 from the tobacco rod 6 flows through the mouthpiece 2 correspondingly slowly and an intimate mixture with the suctioned ventilation air takes place can.
