Description

The invention relates to a capsule for insertion into a head of a hookah, comprising a capsule body and a lid with at least one opening, wherein the capsule body and the lid enclose a portion space in which a single portion of water pipe tobacco is present, and wherein the lid by a weld moisture-tight is connected to the capsule body. Furthermore, the invention relates to a method for producing such a capsule and a capsule produced by such a method. The invention also relates to a machine of the tobacco processing industry for producing a capsule for insertion into a head of a water pipe.

Hookahs, also called shishas, have been used for centuries for tobacco consumption. In the hookah, a multi-flavored moist tobacco material is smoked, which is essentially a mixture of raw tobacco, molasses and glycerin. Molasses is a honey-like dark brown sugar syrup that is a by-product of sugar production and contains about 60% sugar. Unlike other tobacco products such as cigarettes or cigars, hookah tobacco is not burned. When using a hookah, the tobacco material is heated so that its contents evaporate or fume away. For this purpose, a single portion of tobacco material is introduced into the head of a hookah and then covered as possible airtight example, with an aluminum foil. The aluminum foil is then perforated. On the top of the water pipe head thus prepared, for example, a charcoal tablet or a piece of red-hot charcoal is placed for heating the tobacco material. The structure and function of a hookah are also, for example, in the DE 10 2015 200 951 A1 by the applicant Hauni Maschinenbau GmbH, Hamburg.

The preparation of the hookah is relatively expensive. So the moist and sticky tobacco material must be manually filled in the head of the hookah and loosened up. Then the pipe bowl with the aluminum foil must be closed as close as possible, which requires a certain amount of practice just like the subsequent perforation. Easier and faster is the filling of the head of a water pipe with a capsule in which the water pipe tobacco is filled. Such a capsule is for example from the EP 2 179 667 B1 known.

A capsule for insertion into the head of a hookah consists of a capsule body which is closed with a sieve-shaped lid. The capsule body and the lid surround a serving compartment containing a single serving of water pipe tobacco. Before the capsule is used, adhesive seals on the lid and bottom of the capsule body are removed. These seal openings in the lid and in the floor. After removing the seals, the openings are exposed, so that fresh air can penetrate into the capsule. In addition, emerging from the water pipe tobacco combustion products and / or evaporating substances can escape from the capsule.

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

The object is achieved by a capsule for insertion into a head of a hookah, comprising a capsule body and a lid with at least one opening, wherein the capsule body and the lid enclose a portion space in which a single portion of water pipe tobacco is present, and wherein the lid by a Weld seam is moisture-tightly connected to the capsule body, and wherein the capsule is formed by the fact that the weld is generated without auxiliary material and the lid and the capsule body are connected by the weld directly to each other.

In the context of the present description, "auxiliary-free" means that the connection between the two components is made without supporting substances. No substances or auxiliaries are used that support the formation of the weld joining the two components. In particular, the components are not connected to one another by adhesive substances or auxiliaries. The connection of the two components takes place exclusively by the auxiliary fabric-free weld and waiving a sealing wax or the like.

It is connected in a non-adjuvant weld only the material of the lid with the material of the capsule body (and vice versa), the two materials form their connection only by the action of welding without supportive effect or action of any excipients. Preferably, the connection between the lid and the capsule body is not only moisture-proof. The weld is preferably designed such that the lid and the capsule body are hermetically connected to each other. In other words, no material can pass through the weld into the capsule or out of the capsule.

The capsule body is for example a manufactured by deep drawing component. The lid is, for example, a rolled component. The capsule body is made of a sheet-closed material. The lid is in particular a sieve, which has a closed and peripheral to the outer radius edge.

When using the capsule in a hookah it is heated to several 100 ° C, so that escape the consumption of the contained in the capsule hookah tobacco its ingredients. For this purpose, for example, a glowing piece of charcoal or a charcoal tablet is placed on the lid of the capsule. In conventional capsules, the lid is attached in many cases with the help of, or at least but using a sealing lacquer on the capsule body. During the strong heating of the capsule, the sealing wax decomposes, releasing undesirable pollutants. There is a risk that these pollutants in the intended consumption of electricity from tobacco smoke, which is undesirable. In the capsule according to the invention is completely dispensed with additives. In particular, the use of sealing wax is dispensed with. Capsule body and lid are auxiliary-free and directly connected. Thus, it is excluded that combustion products of these auxiliaries reach the smoke stream intended for consumption.

At the glass container 12 is a hose attachment 16 provided on which a hose with a mouthpiece 18 is appropriate. The mouthpiece 18 stands over the hose neck 16 with the above the water 14 existing airspace 22 in the glass container 12 in connection. It is also a valve 20 present, with which the airspace 22 can be ventilated.

The glass container 12 is at its upper end by means of a plug or a seal 24 sealed. Through the seal 24 through a tubular column of smoke extends 26 vertically from the top into the glass container 12 dips and its lower end in the water 14 , ie below the water surface, ends. At an upper end of the column of smoke 26 is a sealing plug 30 present, at the lower end of a shell 28 is appropriate.

On the sealing plug 30 is a head 32 the hookah 10 placed. At the bottom of the head 32 this has a recess 34 on, the shape complementary to the sealing plug 30 is designed so that the head 32 with the smoke column 26 hermetically seals. Inside the head 32 extends in extension of the column of smoke 26 a central smoke channel 36 , The smoke channel 36 is above flow openings 38 with a receiving space of the head 32 connected, in which a capsule 60 located.

The capsule 60 for insertion in the head 32 the hookah 10 includes a single serving of water pipe tobacco 50 , This single serving is located in a portion room 42 the capsule 60 , The capsule 60 comprises a capsule body 62 and a lid 64 , which together the portion space 42 enclose. The lid 64 and the capsule body 62 are through a weld 66 moisture-tight connected.

For consumption of hookah tobacco 50 becomes a charcoal tablet 48 on top of the lid 64 placed. The coal tablet 48 develops during combustion a temperature of several 100 ° C and reaches its maximum heat output within a short time after lighting.

The lid 64 and the capsule body 62 are through a weld 66 moisture-tight connected. The weld 66 (in 4 as a cross-stitched area and in 5 indicated by dashed line) is generated without auxiliary agent. The weld 66 connects directly the material of the lid 64 with that of the capsule body 62 , wherein the connection between the two components is made without supporting substances or auxiliaries. Thus, no auxiliaries are used, which is the formation of the weld 66 support. In particular, no additional adhesively acting substances or auxiliaries are used for the connection of the two components. Above all, the use of sealing wax or similar. completely omitted for connecting the components. For a filler-free weld 66 only becomes the material of the lid 64 with the material of the capsule body 62 connected, wherein the materials of these two workpieces form a connection, which results from the welding process and without supporting effect or action of any excipients.

Advantageously, the capsule comprises 60 due to these measures no substances which are present when heating the capsule 60 (for the purpose of drinking hookah tobacco 50 ) decompose or evaporate. The conventional capsules 60 Many times used sealing wax decomposes in the consumption of the water pipe tobacco 50 occurring high temperatures. The decomposition products may enter the smoke stream intended for consumption, which is undesirable. This will be at the capsule 60 advantageously avoided in accordance with aspects of the invention.

The weld 66 is preferably carried out so stable and resistant that it is pressure-tight to at least a pressure difference of 0.5 bar. The weld 66 So it stays stable and dense, even if between the portion space 42 and one capsule 60 surrounding space 74 a pressure difference of 5 bar prevails. This applies both in the case that in the portion space 42 overpressure prevails as well as in the event that in the portion space 42 a negative pressure prevails. To the portion space 42 Airtight, those are in the ground 76 of the capsule body 62 existing lower openings 68 with a lower seal 78 locked. The in the lid 64 existing upper openings 46 (see. 1 and 2 ) are with an upper seal 80 locked. The upper seal 80 and also the lower seal 78 are each provided with a tear-off tab 82 so that the seals 78 . 80 easy to remove manually.

The lid 64 For example, it is similar to a sieve, ie it has a plurality of upper openings 46 on, of which in 5 some are indicated. The floor 76 of the capsule body 62 also has at least one opening 68 and is also preferably configured similar to a sieve.

The capsule body 62 (see. 4 ) includes one of the portion space 42 pointing away and outwardly projecting sealing edge 72 , In the area of the sealing edge 72 is the capsule body 62 in a first location 84 bent outwards and in a second position 86 in the opposite direction inwards in the direction of the portion space 42 bent back. The material of the capsule body 62 So it is in the area of the sealing edge 72 crimped. This is a border area 88 of the lid 64 between the first location 84 and the second location 86 locked in. The border area 88 (see. 5 ) of the lid 64 runs along an outer edge of the lid 64 along its entire circumference. The border area 88 of the lid 64 corresponds approximately to that area of the lid 64 in which this between the first location 84 and the second location 86 the sealing edge 72 of the capsule body 62 is included. The first location 84 and the second location 86 of the capsule body 62 are through the weld 66 with the lid 64 , more precisely the edge area 88 of the lid 64 , connected.

Besides, with the stamp 102 a sonotrode 106 connected. When performing a method of manufacturing a capsule 60 first, the capsule body 62 in the transport direction T the machine 96 fed and into the anvil 100 inserted. Subsequently, the lid 64 fed and on the capsule body 62 positioned. The Stamp 102 is using the traversing device 104 in the lifting direction H against the anvil 100 drove and pressed the lid 64 in its edge area 88 against the capsule body 62 and thus against the anvil 100 , Subsequently, an ultrasonic welding process is carried out in which the sonotrode 106 the stamp 102 excites to an ultrasonic vibration. The Stamp 102 , the anvil 100 and the sonotrode 106 together form an ultrasonic welding device in this sense.

Through the weld 66 become the capsule body 62 and the lid 64 moisture-tight connected. This is the weld 66 with the machine of the tobacco processing industry 96 Produced without additives, leaving the lid 64 and the capsule body 62 through the weld 66 be directly connected.

The contact pressure is for example between 1200 N and 2000 N. The sonotrode 106 is excited to torsional oscillations, for example, which have an amplitude between 24 microns and 36 microns. The penetration depth of the ultrasonic welded joint produced in this way is for example between 30 .mu.m and 80 .mu.m. The welding time is advantageously only between 110 ms and 210 ms. Subsequently, a holding time of between 160 ms and 240 ms is optionally provided to complete the welding process.

A material thickness of the capsule body 62 is for example between 50 microns and 200 microns. The same applies to the material thickness of the lid 64 , The ultrasonic frequency with which the sonotrode 106 is excited, for example, lies between 18 kHz and 22 kHz. The mentioned parameters have proven to be particularly advantageous for the production of an ultrasonic welded joint.

The lid 64 and the capsule body 62 are preferably produced by a drawing process, for example in a deep-drawing process, from a blank, such as an aluminum sheet or an aluminum foil. In this drawing process, the surfaces of the blank of the lid 64 and the blank of the capsule body 62 subjected to a drawing oil. Before the connection of the capsule body 62 with the lid 64 , it is neither required the lid 64 still the capsule body 62 to clean and in particular to free from the drawing oil. It is still possible, a reliable weld 66 between the two components. The same applies if the connection area 108 between the two components, for example by wet hookah tobacco 50 is contaminated. This also does not mean that no reliable connection can be made. The contamination thus plays for the quality of the welded joint produced 66 not matter.

The manufactured capsule 60 becomes in transport direction T from the machine of the tobacco processing industry 96 fed to the next process step. Advantageously, the ultrasonic welding process only requires a very short process time, so that with the machine the tobacco processing industry 96 a large throughput can be achieved with low unit costs.
