Description

  The present invention is a capsule that is inserted into the head of a water pipe, and the capsule includes a capsule body and a cover having at least one opening, and the capsule body and the cover are disposed therein. The capsule relates to a capsule that includes a portion chamber in which there is a cigarette for a water pipe and the cover is joined to the capsule body in a moisture-proof manner by a weld seam. The invention also relates to a method for producing such a capsule and a capsule produced by such a method. Furthermore, the invention also relates to a machine in the tobacco processing industry for producing a capsule for insertion into the head of a water pipe.

  Water pipes, also called shisha, have been used for centuries for tobacco intake. In a water pipe, a plurality of flavored wet tobacco materials are smoked, which is essentially a mixture of raw tobacco, molasses and glycerin. Molasses is a honey-like dark brown liquid sugar that is obtained as a by-product of sugar products and contains about 60% sugar. Unlike other tobacco products such as cigarettes or cigarettes, it does not burn tobacco for water pipes. When a water pipe is used, the tobacco material is heated so that its components evaporate and more specifically burn out. For this purpose, a batch of tobacco material is introduced into the water pipe head and then covered as tightly as possible, for example with aluminum foil. Next, the aluminum foil is perforated. In order to heat the tobacco material, a charcoal tablet or piece of red hot charcoal is placed, for example, on the upper side of the water pipe head thus prepared. Furthermore, for example, in US Pat. No. 5,077,097, filed by Hauni Machine (Hauni Machinechinbau GmbH) in Hamburg, the construction and function of a water pipe is also described.

  The preparation of the water pipe takes a relatively long time. Therefore, wet and sticky tobacco materials must be manually filled and loosened on the head of the water pipe. And the pipe head needs to be sealed as tightly as possible with aluminum foil, so as with the subsequent drilling, the procedure requires some practice. It is easier and faster to fill the head of the water pipe with a capsule whose interior is filled with tobacco for the water pipe. Such a capsule is known, for example, from US Pat.

  The capsule to be inserted into the water pipe head consists of a capsule body, which is sealed with a sieve-shaped cover. The capsule body and cover surround a portion chamber containing a single water pipe cigarette. Prior to using the capsule, the adhesive seals present on the cover and bottom of the capsule body, respectively, are removed. The aforementioned adhesive seal seals the opening present in the cover and the bottom. When this seal is removed, the opening is exposed so that fresh air can penetrate into the capsule. In addition, combustion products and / or evaporating substances resulting from tobacco for water pipes can be released from the capsule.

German Patent Application Publication No. 1020150200951 European Patent No. 2179667

  It is an object of the present invention to provide an improved capsule for insertion into the head of a water pipe, an improved method of manufacturing a capsule, and a machine in the tobacco processing industry for manufacturing an improved capsule.

  This object is achieved by a capsule which is inserted into the head of a water pipe, said capsule comprising a capsule body and a cover having at least one opening, the capsule body and the cover being inside thereof. Including a portion chamber in which a single water pipe cigarette is present, the cover is a capsule that is welded to the capsule body in a moisture-proof manner by a weld seam, and the capsule is produced without an auxiliary material. And the cover and the capsule body are further formed by being directly joined together by the weld seam.

  In the context of the present specification, “without auxiliary material” means that the joint between the two components is made without a support material. No substance or auxiliary material is used to support the formation of the weld seam that joins the two components. In particular, the components are not joined together by substances or auxiliary materials that act to adhere. The two components are joined only by a weld seam that does not contain auxiliary materials and at the same time without using a sealing braze or the like.

  In the case of a welded seam that does not contain any auxiliary material, only the material of the cover is joined with the material of the capsule body (and vice versa), and the two materials are not subject to any support or influence of the auxiliary material The joint is formed only by the action of welding. Preferably, the joint between the cover and the capsule body is not only moisture proof. The weld seam is preferably designed in such a way that the cover and the capsule body are sealed together. In other words, the material cannot pass through the weld seam into or out of the capsule.

  The capsule body is a component manufactured by, for example, deep drawing. The cover is, for example, a rolled component. The capsule body is made of a two-dimensionally closed material. The cover is in particular a sieve with closed edges extending circumferentially on the outer radius.

  When the capsule is used in a water pipe, it is heated to several hundred degrees Celsius, thereby allowing the aforementioned tobacco components to escape to ingest the water pipe tobacco contained within the capsule. For this purpose, for example, a piece of red hot charcoal or charcoal tablet is placed on the cover of the capsule. In the case of conventional capsules, in many cases using a wax seal, the cover is fixed on the capsule body by using at least the wax seal. When the capsule is subjected to excessive heating, the wax seal breaks down, resulting in the release of undesirable contaminants. There is a risk that these pollutants will enter the cigarette smoke stream intended for consumption, which is an undesirable aspect. In the case of the capsules according to the invention, the additives are made completely. In particular, the use of a wax seal is not used. The capsule body and the cover do not contain any auxiliary material and are joined directly to each other. It is therefore not a problem that the combustion products of these auxiliary materials enter the smoke stream intended for ingestion.

  According to an advantageous embodiment, the weld seam is regularly structured.

  In particular, it is periodically structured, for example with intersecting grooves. Such intersecting grooves have, for example, a pitch of 50 μm to 350 μm, in particular a pitch of 100 μm to 300 μm, and in particular a pitch of 150 μm to 250 μm. This groove appears in particular with a depth of 30 μm to 70 μm and in particular with a depth of 40 μm to 60 μm.

  The weld seam structuring may provide a reliable and reliable bond between the capsule body and the cover.

  According to a further embodiment, the capsule is further formed by the feature that the weld seam provides a bond between the cover and the capsule body, wherein the weld seam has a pressure of at least 0.5 bar. The difference is pressure resistance.

  In other words, the weld seam isolates the portion chamber from the surrounding environment, and a pressure difference of at least 0.5 bar overcomes the portion chamber and the surrounding space while preventing the weld seam from breaking. It is as stable as possible. Preferably, the weld seam is provided to remain stable in situations where there is an overpressure of 0.5 bar in the portion chamber relative to the surrounding space. However, conversely, the portion chamber is equally possible to a reduced pressure of 0.5 bar compared to the surrounding space. Even in such a case, the weld seam remains stable.

  Furthermore, it is provided in particular that the cover is a sieve with a plurality of openings. The capsule body in particular has at least one opening. For example, the plurality of openings are provided in the form of a sieve, for example. This opening / these openings are preferably provided at the bottom of the capsule body, which is located on the opposite side of the cover. Thus, fresh air can flow into the capsule and the generated fragrance can flow out of the capsule when the water pipe tobacco is heated.

  According to another advantageous embodiment, it is provided that at least one opening of the cover is sealed in a moisture-proof and / or pressure-resistant manner with a manually removable seal.

  Even the opening present at the bottom of the capsule body is sealed, in particular, by a moisture-removable seal that can be removed manually. A manually removable seal, for example, has a stripping tab so that the seal can be easily removed prior to intake of a water pipe cigarette. The moisture-proof packaging for water pipe tobacco facilitates the storage of water pipe tobacco as described above.

  According to a further advantageous embodiment, the capsule has a sealing edge protruding outwardly from the capsule body away from the portion chamber, the weld seam being an edge region adjacent to the outer edge of the cover Extending along the circumference of the cover, the sealing edge of the capsule body is bent outwardly in the first layer and inwardly in the opposite direction in the direction of the portion chamber in the second layer The edge region of the cover is encapsulated between the first layer and the second layer, and the first and second layers of the capsule body are joined together with the cover by a weld seam. It is further formed by that.

  The sealing edge of the capsule is provided to seal the capsule from the sealing shoulder at the head of the water pipe. Thus, advantageously, air adjacent to the capsule is prevented from being drawn into the interior of the water pipe. Furthermore, a particularly reliable and stable connection between the cover and the capsule body can be provided in the sealing edge by the flanged sealing edge of the capsule body.

  Aluminum is preferably provided as the material for the capsule, ie the capsule body and cover. For example, aluminum suitable for food packaging. The material thickness of the capsule body and / or cover is in particular from 50 μm to 200 μm, and in particular from 100 μm to 150 μm. The thickness of these materials has proven particularly advantageous in the capsule manufacturing field. The capsules have in particular a diameter of 40 mm to 80 mm, in particular 50 mm to 70 mm, and more particularly 55 mm to 65 mm. The sealing edge has in particular a width of 1 to 3 mm (measured in the radial direction). The height of the capsule, measured in a direction at least approximately perpendicular to the plane in which the cover extends, is in particular 10 to 30 mm, and in particular 15 to 25 mm. The opening present in the cover has in particular a diameter of 1 mm to 2 mm. The opening present at the bottom of the capsule body has in particular a diameter of 2 mm to 6 mm.

  According to another embodiment, the cover and the capsule body are joined together by a plurality of weld seams. For example, the weld seams are at least substantially parallel to each other. Furthermore, they are for example concentric.

  This object is also achieved by a method of manufacturing a capsule that is inserted into the head of a water pipe, the capsule comprising a capsule body and a cover having at least one opening, The capsule body and the cover include a portion chamber in which a single cigarette for water pipe exists, and the cover and the capsule body are disposed relative to each other and joined to each other in a moisture-proof manner by a weld seam. This method is further formed by the fact that the weld seam is produced without auxiliary material and that the cover and the capsule body are joined directly to each other by the weld seam.

  The capsule manufacturing method has the same or similar advantages, as already mentioned with respect to the capsule itself, and therefore does not need to be repeated.

  This method is advantageously further developed by the feature that the cover and the capsule body are joined together by ultrasonic welding.

  Alternatively, a laser welding process is provided whereby the capsule body and cover are joined directly to each other without auxiliary material. This laser welding process can be carried out with or without a welding wire. If the laser welding process is not considered an auxiliary material and is performed with the help of a welding wire that is not representative of such a material, the process is also called a plasma welding process.

  The ultrasonic welding preferably has a capsule body and / or cover material thickness of 50 μm to 200 μm, the ultrasonic welding is performed at a contact pressure of 1200 N to 2000 N, and the welding time is 110 ms to 210 ms. Yes, the amplitude of the ultrasonic vibration is 24 μm to 36 μm and / or is further developed by the fact that the ultrasonic frequency is 18 kHz to 22 kHz.

  Joining by ultrasonic welding is preferably produced by structuring. In particular, the joining by means of periodically structured ultrasonic welding is produced in particular by joining by intersecting grooves.

  The intersecting grooves have, for example, a pitch of 50 μm to 350 μm, in particular a pitch of 100 μm to 300 μm, and in particular a pitch of 150 μm to 250 μm. The weld seam is produced in particular with a groove having a depth of 30 μm to 70 μm, and in particular a depth of 40 μm to 60 μm. Such parameters have proven to be particularly suitable for producing a reliable and auxiliary material-free joint between the cover and the capsule body.

  According to another embodiment, the cover and the capsule body are manufactured from a blank by a drawing method (particularly a deep drawing method), and in the drawing method, the drawing oil is applied to the blank that becomes the cover. It is provided that the squeezing fluid is neither washed on the cover nor the capsule body before being applied to the surface and the surface of the blank that will become the capsule body, before joining the cover of the capsule body.

  In other words, it is not necessary to pre-treat each surface of the two components that are to be joined together. Despite the drawing oil present on the surface, reliable weld joints can be provided. Needless to say, this also applies to the event that the tobacco for water pipes or its components enter the area of the weld joint to be produced. This contamination of the joint area does not mean that a reliable weld joint can no longer be produced. On the contrary, it is always possible to produce reliable joints, in particular using the above-mentioned processing parameters, so that short processing times are achieved. Thus, the welding time is, for example, only 110 ms to 210 ms, after which a holding time of approximately 160 ms to 240 ms, which is approximately the same duration, is sufficient to complete the weld joint.

  Furthermore, in particular, it is provided that at least one opening of the cover is sealed in a moisture-proof manner with a manually removable seal.

  By sealing the existing opening in the cover and the opening existing at the bottom of the capsule body, in particular, the capsule and the water pipe tobacco contained therein can be easily transported and stored.

  According to a further advantageous embodiment, the capsule body comprises a sealing edge protruding outwardly away from the portion chamber, the sealing edge of the capsule body being bent outwardly at the first layer. The cover is placed on the first layer of the sealing edge and the cover is folded back inward toward the portion chamber with the second layer in the opposite direction so that the edge region of the cover The first and second layers of the capsule body are welded extending along the periphery of the cover in the edge region adjacent to the outer edge of the cover. It is provided that the seam joins with the cover.

  The capsule body material is flanged at the sealing edge and the cover is placed between the flange layers, thereby forming a particularly reliable sealing joint between the components.

  According to a further embodiment, it is provided that the capsule body is inserted into the anvil so that the cover is pressed with a punch against the edge region of the capsule body and against the anvil. For example, with a predetermined contact pressure of 1200 N to 2000 N, the punch is pressed onto the cover, the capsule body and against the anvil in the welding area. In this way, an ultrasonic weld is created, preferably it is structured. For this purpose, the punch is connected to a sonotrode, which vibrates with an amplitude of 24 μm to 36 μm. The sonotrode vibration mode is preferably torsional vibration. The penetration depth of the produced ultrasonic welding is preferably 30 μm to 80 μm.

  This object is further achieved by a capsule that is inserted into the head of a water pipe, said capsule being manufactured according to a method according to one or more of the aforementioned embodiments. Such capsules have the same or similar advantages as already mentioned above.

  Finally, this object is achieved by a machine in the tobacco processing industry that manufactures a capsule according to one or more of the preceding embodiments. The machine comprises an ultrasonic welding device with an anvil and a punch, the anvil being designed to receive a capsule body, the punch being positioned opposite the anvil, the punch being covered And to the sealing edge of the capsule body and to the anvil are driven and movable in such a way that they can be pressed with a predetermined contact pressure. In this case, the capsule manufacturing method described in accordance with one or more of the foregoing exemplary embodiments is performed by an ultrasonic welding apparatus. In other words, machines in the tobacco processing industry are designed to perform a method according to one or more of the aforementioned aspects.

  Even machines for the tobacco processing industry have the same or similar advantages as already mentioned above with respect to capsules and with respect to the method of manufacturing capsules. Particularly advantageous is the short processing time required to join the capsule body with the cover. Thus, machines in the tobacco processing industry can achieve high throughput and corresponding low unit costs for joining the individual components of the capsule.

  Other features of the invention will be apparent from the description of embodiments of the invention, along with the claims and accompanying drawings. Embodiments of the invention may satisfy individual features or combinations of features.

  The present invention is described below by way of example embodiments with reference to the drawings without limiting the general idea of the invention, but with respect to all of the details of the invention that are not described in greater detail in the text. Which explicitly refers to the drawings. The drawings are shown as follows.

FIG. 1 is a simplified diagram of a prior art water pipe in schematic form. FIG. 2 is a simplified cross-sectional view of the head of a water pipe having an inserted capsule in schematic form. FIG. 3 is a simplified cross-sectional view of a capsule in schematic form. FIG. 4 is a detailed view thereof. FIG. 5 is a simplified plan view from the top side of the capsule in schematic form. FIG. 6 is a simplified plan view from the bottom side of the capsule in schematic form. FIG. 7 is a simplified detailed view of a structured weld seam in schematic form. FIG. 8 is a simplified diagram of a machine in the tobacco processing industry for manufacturing capsules in schematic form.

  The same or similar components and / or parts are marked with the same reference numerals in the drawings and are therefore omitted in any case in the redrawn display.

  FIG. 1 shows a simplified diagram of a water pipe 10 according to the prior art in schematic form. The aforementioned water pipe comprises a glass container 12 in the lower region, which is filled with water 14. A hose attachment portion 16 to which a hose having a mouthpiece 18 is attached to the glass container 12 is provided. The mouthpiece 18 is connected to the air space 22 existing on the water 14 in the glass container 12 through the hose attachment portion 16. There is also a valve 20 that can ventilate the airspace 22.

  The glass container 12 is sealed at its upper end by a plug or alternatively a seal 24. A tubular smoke column 26 extends through the seal 24 and is vertically inserted into the glass container 12 from above, with its lower end terminating in the water 14, ie below the surface of the water. A sealing plug 30 is provided at the upper end of the smoke column 26, and a bowl 28 is attached to the lower end thereof.

  The head 32 of the water pipe 10 is disposed on the sealing plug 30. The lower end of the head 32 has a recess 34 designed to be complementary to the shape of the sealing plug 30 so that the head 32 terminates in a hermetic manner with the smoke column 26. Inside the head 32, a central smoke channel 36 extends to an extension of the smoke column 26. The smoke channel 36 is connected through a through flow opening 38 to a receiving chamber in the head 32 where the capsule 60 is located.

  The capsule 60 to be inserted into the head 32 of the water pipe 10 includes a single water pipe cigarette 50. This single dose is placed in the portion chamber 42 of the capsule 60. The capsule 60 comprises a capsule body 62 and a cover 64 that together enclose the portion chamber 42. The cover 64 and the capsule body 62 are joined to each other by a weld seam 66 in a moisture-proof manner.

  A charcoal tablet 48 is disposed on the upper side of the cover 64 for ingesting the water pipe tobacco 50. When the charcoal tablet burns, the charcoal tablet 48 rises to a temperature of several hundred degrees Celsius and reaches its maximum heat output within a short time after ignition. The charcoal tablet then burns over a period of about 20-30 minutes. The aromatic substance from the water pipe tobacco 50 is evaporated by the heat released from the charcoal tablet 48. When using the water pipe 10, the smoker sucks the mouthpiece 18, resulting in a vacuum in the airspace 22 of the glass container 12. Since the aforementioned depressurization continues into the smoke column 26, air is drawn into the capsule 60. Fresh air passes through the upper opening 46 present in the cover 64 and into the portion chamber 42 of the capsule 60. Smoke and fragrance produced by heating the water pipe tobacco 50 exits the capsule 60 on the bottom side of the capsule 60 through a lower opening 68 present at the bottom of the capsule body 62. The emitted or more evaporated fragrance material, along with the air flow, passes down the smoke column 26 and travels downward into the water 14 where the fragrance material is bubbled upward. Foaming enters the airspace 22 and then passes through the hose fitting 16 and mouthpiece 18 towards the ingestor.

  FIG. 2 is a simplified view of a head 32 of a water pipe 10 having an inserted capsule 60 in schematic form, showing a schematic simplified cross-sectional view. The head 32 includes a sealing shoulder 70 adjacent to a sealing edge 72 that projects outwardly of the capsule 60. The sealing edge 72 seals the capsule 60 at least approximately airtight from the head 32 of the water pipe 10. Thus, in particular, secondary air that does not flow into the portion chamber 42 of the capsule 60 as a result of the vacuum in the smoke column 26 is avoided from flowing into the smoke column. In this way, it is also ensured that all of the inhaled air transports the fragrance released from the water pipe tobacco 50.

  FIG. 3 shows a simplified cross-sectional view of the capsule 60 in schematic form. FIG. 4 shows a detailed view of FIG. 3 in the region of the sealing edge 72 of the capsule 60. FIG. 5 shows a simplified plan view of the capsule 60 from its upper side in schematic form. FIG. 6 shows a simplified plan view of the capsule 60 from its lower side in schematic form. The capsule 60 will be described in more detail below with reference to FIGS.

  The cover 64 and the capsule body 62 are joined to each other by a weld seam 66 in a moisture-proof manner. The weld seam 66 (shown as a dashed line in FIG. 5 as the area indicated by the intersecting lines in FIG. 4) is produced without auxiliary material. The weld seam 66 directly joins the material of the cover 64 with the material of the capsule body 62, and the joint between the two components is made without any support material or auxiliary material. Accordingly, auxiliary materials that support the formation of the weld seam 66 are not used. In particular, no additional substances or auxiliary materials that act in an adhesive manner are used to join the two components. Above all, the use of a sealing wax or the like for joining the components is not used completely. In the case of a weld seam 66 that does not include an auxiliary material, only the material of the cover 64 is joined to the material of the capsule body 62, so that the materials of these two members are welded without any support action or influence of the auxiliary material. A bond produced by processing is formed.

  As a result of these measures, the capsule 60 is advantageously free of any material that decomposes or evaporates when the capsule 60 is heated (for the purpose of ingesting the water pipe tobacco 50). The wax wax frequently used in the conventional capsule 60 decomposes at the high temperatures generated during intake of the water pipe tobacco 50. The degradation products enter the smoke stream intended for ingestion and are an undesirable aspect. This feature is advantageously avoided by the capsule 60 according to aspects of the present invention.

  The weld seam 66 is preferably designed to be so stable and resistant that it is pressure resistant with a pressure differential of at least 0.5 bar. As a result, the weld seam 66 remains stably sealed even with a 5 bar pressure differential between the portion chamber 42 and the space 74 surrounding the capsule 60. This applies not only to the overpressure in the portion chamber 42 but also to the case where the inside of the portion chamber 42 is depressurized. In order to hermetically seal the portion chamber 42, the lower opening 68 present at the bottom 76 of the capsule body 62 is sealed with a lower seal 78. The upper opening 46 present in the cover 64 (see FIGS. 1 and 2) is sealed with an upper seal 80. The upper seal 80 and likewise the lower seal 78 are each provided with a stripping tab 82 so that the seals 78, 80 can be easily removed by hand.

  The cover 64 has, for example, a configuration similar to a sieve. That means that the aforementioned cover has a plurality of upper openings 46, some of which are shown in FIG. The bottom 76 of the capsule body 62 preferably also has at least one opening 68 and is configured similar to a sieve.

  The capsule body 62 (see FIG. 4) includes an outwardly projecting sealing edge 72 that is directed away from the portion chamber 42. In the region of the sealing edge 72, the capsule body 62 is bent outward at the first layer 84 and folded back towards the portion chamber 42 at the second layer 86 in the opposite direction. Accordingly, the material of the capsule body 62 is flanged in the region of the sealing edge 72. In this case, the edge region 88 of the cover 64 is enclosed between the first layer 84 and the second layer 86. The edge region 88 (see FIG. 5) of the cover 64 extends along the outer edge of the cover 64 along the entire outer periphery thereof. The edge region 88 of the cover 64 generally corresponds to that region of the cover 64, where the aforementioned cover comprises the first layer 84 and the second layer 86 of the sealing edge 72 of the capsule body 62. Enclosed between. The first layer 84 and the second layer 86 of the capsule body 62 are joined together with the cover 64 and more precisely with the edge region 88 of the cover 64 by means of a weld seam 66.

  FIG. 7 shows a simplified detailed view of an illustrative structured weld seam 66 in schematic form. The structures used in this specification are only partially shown, but are periodically continuous as shown by dots. The periodically intersecting grooves have a pitch of 50 μm to 350 μm, for example. The depth of the groove is, for example, 30 μm to 70 μm. This means that there is a difference in the height direction from 30 μm to 70 μm between the trough 90 and the raised portion 92 of the intersecting grooves. The ridges 92 are chamfered on all sides of their sides 94. For example, it is chamfered at an angle of less than 45 °. The pitch of the illustrated intersecting grooves is measured in both directions of the intersecting grooves between adjacent valleys 90, 90 '.

  In the manufacturing method of the capsule 60 to be inserted into the head 32 of the water pipe 10, a machine 96 in the tobacco processing industry shown in a simplified form in a schematic form in FIG. 8 is used as an example.

  The machine 96 includes an capsule body 62 and an anvil 100 for receiving the punch 102, and the punch 102 is disposed opposite the anvil 100. The punch 102 can be moved by the traverse device 104 in the lifting direction H and is pressed by the traverse device 104 against the anvil 100 with a predetermined contact pressure. Further, a sonotrode 106 is connected to the punch 102. When the manufacturing method of the capsule 60 is executed, the capsule body 62 is first supplied to the machine 96 in the transport direction T and inserted into the anvil 100. Next, the cover 64 is supplied and positioned on the capsule body 62. The punch 102 is moved relative to the anvil 100 with the aid of the traverse device 104 in the lifting direction H, pressing the cover 64 against the capsule body 62 in its edge region 88, with respect to the anvil 100. Also press. Thereafter, ultrasonic welding is performed, but the sonotrode 106 excites the punch 102 to ultrasonic vibration. In this context, the punch 102, the anvil 100 and the sonotrode 106 together form an ultrasonic welding device.

  The capsule body 62 and the cover 64 are joined to each other in a moisture-proof manner by a weld seam 66. In this case, the weld seam 66 is manufactured without auxiliary material by a machine 96 in the tobacco processing industry such that the cover 64 and the capsule body 62 are joined together directly by the weld seam 66.

  The contact pressure is, for example, 1200N to 2000N. The sonotrode 106 is excited by torsional vibration having an amplitude of 24 μm to 36 μm, for example. The penetration degree of the ultrasonic welded joint manufactured by this method is, for example, 30 μm to 80 μm. The welding time is advantageously only 110 ms to 210 ms. Thereafter, a hold time of 160 ms to 240 ms is optionally provided to complete the welding operation.

  The material thickness of the capsule body 62 is, for example, 50 μm to 200 μm. The same applies to the material thickness of the cover 64. The ultrasonic frequency with which the sonotrode 106 is excited is, for example, 18 kHz to 22 kHz. The aforementioned parameters have proven particularly advantageous for the production of ultrasonic welded joints.

  The cover 64 and the capsule body 62 are preferably manufactured from a blank such as an aluminum sheet or an aluminum foil, for example, by a drawing method such as a deep drawing method. In the case of this drawing method, the drawing oil is applied to the surface of the blank that becomes the cover 64 and the surface of the blank that becomes the capsule body 62. Before joining the cover body 62 to the cover 64, it is not necessary to clean either the cover 64 or the capsule body 62, and in particular it is not necessary to eliminate any squeezing fluid on either the cover or the capsule body. Nevertheless, a reliable weld seam 66 can still be produced between the two components. The same applies if the junction area 108 between the two components is contaminated, for example by the wet water pipe tobacco 50. This aspect does not mean that a reliable bond can no longer be produced. Thus, contamination is not a factor in the quality of the weld joint 66 that is manufactured.

  The manufactured capsule 60 is transported in the transport direction T from the machine 96 in the tobacco processing industry to the next processing step. Advantageously, ultrasonic welding requires only a very short processing time so that high throughput can be achieved at low unit cost using the machine 96 in the tobacco processing industry.

  Not only all of the features described above, but also the individual features disclosed in combination with other features, including those obtained from the drawings alone, are considered alone and in combinations that are essential to the invention.
