EP2503910B1 - Method for producing a mouthpiece cover of a cigarette - Google Patents

Description

The invention relates to a method for producing a

Cigarette mouthpiece according to the preamble of claim 1.

Furthermore, the invention has a cigarette mouthpiece for the subject.

The terms "mouthpiece coating" and "filter wrapper" are understood in this document to mean "tipping paper", however, by use of the terms "mouthpiece coating" and "filter wrapper", it is meant that the words "mouthpiece coating" and "filter wrapper" are used used materials must not always be a paper, so the "tipping paper" or the "filter wrapper" could be made for example of a plastic film, cellophane, etc.

From the US40943424 A For example, a method for producing a mouthpiece covering of a cigarette has been disclosed, in which a tipping paper is provided with randomly arranged microholes, in order to ensure a ventilation of the mouthpiece and thus to contribute to a pollutant reduction.

In the manufacture of cigarettes, it may also be necessary to cut the tipping paper exactly, especially when a logo is applied to the tipping paper.

The document EP 1 252 832 A2 relates to a method for producing a cigarette mouthpiece, wherein a transparent filter wrap material is used. The filter wrap material is surrounded by a tipping paper which has a window which allows a view of the underlying Filterhülle. A paper sleeve formed from the tipping paper can be provided with an incorporated or glued transparent film as a window.

The document CH 394 912 A refers to a cigarette mouthpiece, which has a covering material with a viewing window, which allows a view of an underlying layer.

The document US2006 / 150991 has a cigarette mouthpiece to the object, in which a partially transparent covering material is used to allow a view of an underlying filter. A disadvantage of the known from the prior art solutions especially that with them, the risk of increased production of rejects goes along.

It is therefore an object of the invention to overcome the disadvantages of the prior art.

This object is achieved by a method of the type mentioned according to the invention by the features of the characterizing part of claim 1.

In this case, a sight opening is understood to be a hole of a size that allows a view of a layer arranged behind the hole with the naked eye.

By the appropriate size of the holes on the one hand a very good ventilation of the mouthpiece is achieved and on the other also created the ability to detect the holes well. In this way, a precise register of the windows to a logo mounted on the mouthpiece and thus a consistent for all mouthpieces positioning of the logo is possible. In addition, the inventive solution also opens up the possibility of different optical configurations of the mouthpiece. For example, a portion of a logo could be placed on a layer visible under the tipping covering, visible through a viewing aperture, while the other portion of the logo could be mounted on the tipping. The visibility of the holes also makes it easier to control whether the position of the sight holes is the desired one and the same for all mouthpieces produced, so that a consistent quality of the produced mouthpieces can be guaranteed even with very large production quantities compared to conventional perforations. An inventive mouthpiece covering for a cigarette mouthpiece thus has at least one viewing opening.

An advantageous variant of the invention, which is also characterized by low material costs, provides that the tipping material and / or the filter wrapping material is paper or cellophane.

A particularly good detectability of the viewing holes and a tuning of the ventilation of the mouthpiece can be achieved by providing the mouthpiece covering material and / or the filter covering material with a predeterminable pattern of a plurality of viewing holes.

A variant of the invention, in addition to production-related advantages also good detection of the viewing holes and an exact arrangement of other surface features, such as logos, allows, provides that several, arranged in at least one row sight holes are provided.

In particular, when using mechanical punching or cutting tools, it may be advantageous from a production point of view, if the at least one row is a linear row. As a result, movements of the punching tool can be reduced to a minimum relative to the paper surface, so that a relatively simple tool design is possible. The ventilation of the mouthpiece can be further improved in this case by providing the mouthpiece covering material and / or the filter covering material with at least two mutually parallel rows of viewing holes. It has also been found to be particularly advantageous if at least one window is formed from a plurality of spatially adjacent viewing holes. In this context, it is also advantageous if at least two viewing holes of different sizes are formed.

Conveniently, the viewing holes are made by sectioning punching and / or cutting the tipping material and / or the filter wrap material. These methods have been found to be particularly advantageous in terms of material loading and the quality of the viewing holes achieved.

An embodiment of the invention, the particular advantages of which are seen in the fact that in a very simple way a very large freedom in the positioning of the viewing holes is given, is that for the production of the viewing holes, a laser is used.

The production of very high quality view holes can be achieved by using a mechanical punching device to make the view holes. With the use of a mechanical punching device, for example, very sharp-edged borders and an exact hole size can be achieved.

An advantageous variant of the invention, which prevents the passage of glue during the application of the mouthpiece covering or the filter wrap material on a filter strand, provides that under the mouthpiece covering material and / or filter wrapper material provided with at least one viewing opening a continuous layer of a transparent or semitransparent material, for example Plastic, paper or cellophane is applied, which covers the viewing opening. The term "transparent" is understood here to mean that the material used is a material that is transparent in the visible electromagnetic spectral range. For the purposes of this document, transparent is thus understood as meaning a material which can clearly identify a layer arranged behind the material from the direction of the observer. The term semitransparent represents a gradation of transparency. In a semi-transparent material, the visibility of the layer disposed behind the material is reduced over that of a transparent material. This can be done for example by coloring the transparent material.

A particularly favorable embodiment of the invention provides in this case that a cellophane layer is applied as the layer for covering the viewing opening. The CeUophanschicht can be made transparent or non-transparent. In the case of a transparent cellophane layer, this allows a view of an underlying layer or layers.

According to a preferred embodiment of the invention, the layer covering the viewing opening can be glued, stamped, etc. on the mouthpiece covering material and / or filter covering material provided with at least one viewing opening. This can, as also mentioned below, by means of hot or cold gluing, hot stamping, etc. done.

According to a further variant of the invention, provision may be made to apply a layer of transparent or semitransparent material to produce the viewing apertures on at least two strips of a tipping or filter paper whose mutually facing edges are spaced apart from one another. The mouthpiece covering material or filter wrapper material according to the invention can in this case be formed from at least two paper strips and at least one plastic strip, in particular a cellophane strip. The plastic strip is in this case arranged between the two paper strips and is connected to these. In the above-mentioned way, can be easily a visual opening realize without this a Heraustanzen or cutting out of the viewing openings is required.

To improve the properties of the mouthpiece, in particular with regard to the Durchlüflungseigenschaften, at least one intermediate layer may be disposed between the Mundstückbelagmaterial and the filter wrap material. According to a favorable embodiment of the invention by which the advantages according to the invention are further improved, the at least one intermediate layer may likewise have at least one viewing opening, wherein the at least one viewing opening of the at least one intermediate layer may be smaller than the at least one viewing opening of the mouthpiece covering. This also creates a special visual design of the mouthpiece. An additional advantage of this variant of the invention is that the mouthpiece covering and the filter envelope can be aligned and arranged exactly to one another, since the relative position of these two components relative to one another can be detected optically.

The object underlying the invention can also be solved with a cigarette mouthpiece of the type mentioned, characterized in that the cigarette mouthpiece is formed at least partially transparent and a view through the mouthpiece covering and / or the filter cover is given to an underlying layer.

The tipping pad may be made of paper and have a pattern of multiple viewing holes. Several sight holes can also be arranged in at least one row, wherein the row can basically be arbitrarily shaped. For example, a connecting line through the row could be a straight line, a sinusoidal or an arbitrarily shaped curve.

It is particularly advantageous with regard to an adhesive application during the production process of a cigarette when the mouthpiece covering is coated with a layer of transparent and / or semitransparent material covering the at least one viewing opening, since in this way adhesive penetration through the viewing opening can be prevented.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

According to Fig. 1 For example, an apparatus 1 according to the invention for producing a mouthpiece covering 2 and / or a filter envelope of a cigarette has at least one means 3 for cutting and / or punching sight holes 4 into a mouthpiece covering material and / or filter wrap material.

The means 3 for cutting and / or punching may be for example a laser system or a mechanical punching device.

The tipping material and filter wrap are preferably paper. But mouthpiece covering 2 and filter cover can be made in principle from any other suitable material, such as a plastic film or a laminate, for example, an aluminum laminated paper, cellophane, steamed materials, knitted fabrics, etc ..

According to the method according to the invention for producing a mouthpiece covering 2 and / or a filter envelope of a cigarette, the mouthpiece covering material and / or a filter wrap material are provided with at least one viewing opening 4 of predeterminable form. For this purpose, the viewing holes 4 are cut or punched into the mouthpiece covering material or the filter wrapper material by means of the cutting or punching means 3.

With the aid of the means 3, the mouthpiece covering material 2 and / or the filter wrapping material can be provided with a predeterminable pattern of a plurality of viewing holes 4. The mouthpiece covering material 2 according to the invention thus has one or more viewing holes 4, which enable or permit a view of an underneathable or arranged layer with the naked eye. For example, the viewing holes 4 may have a diameter between 0.1 mm and 25 mm, preferably between 1 mm and 10 mm. This has in addition to a good detectability of the viewing holes 4 in the production of the cigarette mouthpiece and a good ventilation of the cigarette mouthpiece result.

Examples of different hole shapes and patterns of the viewing holes 4 are in the FIGS. 2 to 7 shown. Thus, the mouthpiece covering 2 of the invention according to the Figures 2-4 have a plurality of arranged in at least one row viewing holes 4. This series can in principle be arbitrarily shaped. So the series can be a linear series or a sinusoidal form ( Fig. 4 ) etc. Also, two or more rows may be arranged side by side or parallel to each other on the mouthpiece covering 2 ( Fig. 2 ).

As in FIG. 2 shown, between each two adjacent sight holes 4 also a logo 5 may be mounted on the Mundstückbehg 2.

According to Fig. 3 it is also possible for a zone perforation 6 to be arranged between two adjacent sight holes 4.

Fig. 5 shows such an arrangement of sight holes 4 and zone perforations 6 in greater detail.

According to Fig. 6 the viewing holes 4 may have any contours. Thus, for example, geometrical basic shapes (circle, triangle, etc.), any stylized shapes (heart, flower, etc.) or also characters can be reproduced as contours of the viewing holes 4.

As in Fig. 7 but also in Fig. 5 illustrated, windows 7 of any shape from several spatially adjacent viewing holes 4 can be formed. It should also be pointed out that in all the above-mentioned embodiments, the viewing windows 4 of one and the same mouthpiece covering 2 and / or one and the same filter envelope can have different sizes.

According to Fig. 8 For example, the position of the viewing holes 4 can be detected accurately by means of an optical sensor 8, for example an infrared sensor. This is of great importance, above all with regard to the production of the cigarette mouthpiece, since precise tailoring and alignment of the mouthpiece lining to the other components of the cigarette mouthpiece to be produced, such as, for example, the filter wrapper, is made possible.

As in Fig. 9 can be arranged in a multi-part construction of a cigarette mouthpiece 9 between the mouthpiece covering 2 and the filter cover 10 and at least one intermediate layer 11.
This intermediate layer 11 may be provided with at least one substance which has a predefinable function, in particular the emission of an aroma and / or the influence of smoke values. For example, the intermediate layer 11 could be made of a paper treated with active substances, such as chemically reactive substances.

Furthermore, the intermediate layer 11 may also have at least one viewing opening 12 through which a view of the underlying layer, for example, on the filter cover 10 is made possible. The filter cover 10 may also have sight holes 13, through which the underlying filter, not shown here may be visible. The viewing holes 12 of the intermediate layer 11 may in this case be smaller than the viewing holes 4 of the tipping paper 2. If the filter cover 10 has viewing holes 13, then they may advantageously also be smaller than the viewing holes 12 of the intermediate layer 11. In the present context means "smaller" of smaller diameter or smaller area.

Of course, a construction of the mouthpiece 9 is possible, in which no intermediate layer 11 between mouthpiece covering 2 and filter cover 10 is provided.

Furthermore, constructions of the cigarette mouthpiece 9 are possible in which a plurality of intermediate layers 11 are arranged between mouthpiece covering 2 and filter cover 10. To achieve special optical effects, the different layers 2, 11, 10 may also be colored (differently). It should also be noted at this point that it is not absolutely necessary in all embodiments of the invention that the filter cover 10 also has to have a viewing opening 13, so the filter cover 10 could also be designed like a conventional filter cover.

According to 10 and 11 a continuous layer 14 of a transparent or semitransparent material, for example plastic, paper, cellophane, etc., which covers the viewing openings 4, can be applied during production under the material of the mouthpiece covering 2 and / or material of the filter cover provided with at least one viewing opening 4 , Preferably, a layer of cellophane is applied as layer 14. The layer 14 can be adhered to the material of the mouthpiece covering 2, for example a tipping paper, and / or the filter cover. The gluing can be done using a hot melt adhesive or by means of a cold glue or other suitable gluing methods such as embossing, etc. For example, the bonding can also take place by means of hot foil stamping.

How out Fig. 12 it can be seen that a glue or adhesive application on the mouthpiece covering 2 by means of a glue roller 15 done. The glue 16 may in this case be applied to an underside of the mouthpiece covering 2. The directions of movement of the mouthpiece covering 2 and the glue roller 15 are in the Fig. 12 to 14 indicated by arrows

Out Fig. 13 can be seen that when applying the glue 16, this can escape through the viewing ports 4. A transmission of the glue 16 through the viewing ports 4 leaves according to Fig. 14 by applying the layer 14 on the material web of the mouthpiece covering 2 prevent. The glue 16 according to the illustrated embodiment is applied to the plastic layer 14, which is preferably a cellophane layer.

After application of the adhesive or glue 16, the material web of the mouthpiece covering 2 or the filter cover 10 can be separated by means of a cutting device in a device for producing a cigarette, a so-called cigarette maker. In a further step, the separated flakes of the mouthpiece covering 2 are glued to filter strands,

Fig. 15 shows a section through a filter strand 17, on which an isolated Plättschen 18 of a mouthpiece covering 2 according to the invention is adhered.

How out Fig. 16 can be seen, the layer 14 can also be arranged only in the area below the viewing ports 4 in order to prevent a glue passage along an adhesive trace can.

As in Fig. 17 shown, the Mundstückbelagmaterial invention is glued after its isolation in platelets in the cigarette maker on a filter strand. The filter strand is in this case arranged between the tobacco strands of a double cigarette. To separate the cigarettes, the filter strand is divided by cutting and the double cigarette separated into two separate cigarettes.

According to Fig. 18 For example, an application of the glue 16 may take place in an area around and under the sight holes 4. But it is also possible that the glue is applied over the entire bobbin width of the mouthpiece covering material.

Finally, it should be noted that the embodiments show only possible embodiments of the inventive solution, the invention is not limited to the specifically illustrated embodiments. In particular, combinations of the individual embodiments are possible with each other, these variations are due to the teaching of the technical action of the subject invention in the skill of those working in this technical field expert. There are also all conceivable embodiments that realize the solution ideas underlying the invention and are not explicitly described or illustrated, or by combinations of individual details of the illustrated and described embodiments are possible, includes the scope of protection. Likewise, the protection also extends to the individual components of the device according to the invention, insofar as they are in themselves essential to the realization of the invention.
