The invention relates to hookahs, especially the bowls of hookahs and a portion of hookah tobacco to be filled into such bowl.
Hookahs comprise a water container. A smoke tube is inserted in this water container, and ends below the surface of the water. A bowl is stuck on the smoke tube, into which bowl a portion of tobacco may be filled. The tobacco in the bowl may be heated by way of glowing charcoal which is applied thereon. Then, the tobacco smoke arising due to the effect of heat, may be sucked through the water via a hose which ends in the air space of the water container.
The tobacco used for hookahs is mixed with sugar molasses, glycerine and aromas, and has a moisture content of 25 to 40 percent by weight, in the countries in which such a high moisture content is permitted. The tobacco prepared in such a manner is offered in tins, which for example contain 1 kilo of hookah tobacco. Most hookah smokers require longer periods of time to consume such a trading quantity. It is only in hookah cafés that such quantities are consumed within short time periods. The tobacco may dry out to a significant extent during storage, and may therefore become compromised with regard to its taste, during the storage.
One disadvantage of the previous manner in which hookah bowls are filled, is the fact that the tobacco must be stirred up in the storage container before the filling of the bowl, in order to distribute the molasses which have partly seeped to the bottom of the container, uniformly again in the tobacco.
A further disadvantage for hookah smokers is the fact, that tobacco accordingly to law in certain countries, may only have a moisture content for example of 5% at the most. For this reason, tobacco which is too dry, may only be purchased in these countries. The thorough mixing of the tobacco with molasses and glycerine requires some effort, and is sticky work which is unpleasant to many smokers. These regulations furthermore prevent original and ready-to-use, branded tobaccos for hookahs from being able to be brought onto the market.
It is therefore the object of the invention, to simplify the filling of bowls of or for hookahs, with tobacco. It is also the object to provide hookah tobacco to the consumer, in a manner such that the higher quality of the tobacco is retained over a longer period of time than was previously the case.
According to the invention, this object is achieved by a cartridge according to claim 1. The tobacco is offered in cartridges which in each case, at the most, contain an individual portion of hookah tobacco. The cartridge has perforations which are advantageously closed in a moisture-tight manner, so that the moisture content of the tobacco is retained. The presentation form of hookah tobacco in portion cartridges has several advantages:
The container wall of the cartridge is usefully formed of aluminium. Alternatively, the container wall may be formed of sheet steel or another metal, or at least a shell part of the container wall may be formed also of a heat-resistant plastic.
The container wall forms at least one shell, in which the tobacco is present. Preferably the shell is forming the body of the cartridge and is closed by a lid. Perforations in this cartridge are closed in a moisture-tight manner by a part which is separate to the container wall of the shell or the lid. The container wall however also forms part of the hermetic closure itself.
Since the container wall must be able to be permeated by fresh air and smoke when smoking, holes must be present in the cartridge inserted into the bowl. If only one shell is formed with the container wall, then this shell is open to the top and has a perforated upper lid covering this opening, which lid again is covered in a moisture-tight manner up to time when the cartridge is used. Thus an opening only needs to be incorporated or provided in the bottom of the shell. The container wall may preferably form a perforated shell and have a separate layer closing the perforation of the shell.
If a layer separate to the container wall is responsible for the sealing of the moisture content of the cartridge, then the container wall may have perforations in the region of the bottom of the shell and/or the upper lid.
The moisture-tight closure is then advantageously formed by a plastic covering. This may be created in the known manner by way of welding a plastic covering around or to the container wall. Such a covering is advantageously evacuated and/or shrunk, in order to assume as little as possible volume, and to protect the contents from the loss of aromas, desiccation and leakage.
The moisture-tight closure preferably is formed of a removable tab above the perforated area of the cartridge only. Such a tab is connected to the container wall in a sealed manner. Bonding agent or a welding may be provided, in order to maintain this connection and keep it sealed. The tab may be formed from the same material as the container wall. It may also be formed of a material which is not heat-resistant. Preferably, it is formed of or have a layer of a thermoplastic plastic material which softens given the addition of energy, and may thus be bonded to the container wall.
If however the moisture-tight closure is formed in the bottom or the top area by the container wall itself, which is not preferred, then this container wall needs to be actively perforated before use of the cartridge. An individual, e.g. metallic tip may be used for perforation. One may also use an apparatus, which cuts or pierces several perforations simultaneously into the container wall. The apparatus may introduce these into the base of the shell or into the upper lid of the shell. This perforation aid may be integrated into a bowl, into which the cartridge must be inserted for smoking.
The cartridge may be subdivided by way of separating walls into partitions, which in each case are filled with the tobacco. This largely prevents a demixing of the tobacco and molasses. The partitions may be filled with differently aromatised tobaccos. The partitions may be arranged in parallel, so that different components of air simultaneously flow through them when smoking, wherein these shares do not mix until outside the cartridge. The partitions may also be arranged in series, so that the sucked air must flow through these one after the other.
With a series arrangement of the partitions, the molasses may be arranged in an uppermost partition, and the tobacco in the partition arranged therebelow. This permits tobacco with a humidity of 5% or less to be used, and the separating wall between the two partitions is to be pierced before lighting up the hookah, so that the molasses impregnate the tobacco. Such a measure satisfies the law which prohibits a high moisture content of tobacco. At the same time, the hookah smokers in this country are provided with a manufactured tobacco preparation, which fulfils the almost ideal conditions for hookahs.
Such a cartridge advantageously has an outwardly projecting sealing edge. The lid and the shell or the closure tab and the shell, or all three, are connected to one another at the sealing edge. The sealing edge may be placed onto a sealing shoulder in the bowl, and thus prevents false air from wrongly flowing past the cartridge instead of flowing through the cartridge.
The cartridge may have a two-layered construction, with a first compartment with tobacco as a first layer, and with a second compartment thereabove as a second layer. The second compartment may merely ensure that the charcoal placed thereon does not lie directly on the first compartment, but is held at a distance thereto. The second compartment may however also be filled with fluid constituents, which serve to moisten a tobacco having the stipulated dryness. One may adhere to the regulations of some countries, which do not permit the sale of moistened tobacco, by way of this separation of fluid ingredients and dry tobacco in two hermetically mutually separated compartments.
The invention further relates to a set for hookahs with a standardised cartridge, as is described above, and with a standardised bowl for a hookah. The bowl in the manner known per se has a bowl wall, an access opening for applying the tobacco into the bowl, and at least one smoke outlet opening. Now the access opening serves for inserting the cartridge. With this set, the shape of the cartridge and the inner shape of the bowl are matched to one another such that the inner shape is filled out by a cartridge or several cartridges essentially abutting up to the bowl wall.
The cartridge fills out the bowl, in a manner such that the volume sucked through the smoke tube must flow through the cartridge. However, it is possible for several cartridges to be arranged above one another in the bowl. The individual cartridge may therefore only contain a part volume of a portion of tobacco. One may further envisage two, three or four part-cartridges having to be joined laterally next to one another, in order to fill out the bowl. Each of these part-cartridges encompasses practically a compartment of a complete cartridge. Only a plurality of these part-cartridges together fills out the bowl in the desired shape.
Another set consists of at least one cartridge, whose container wall encloses the tobacco in a moisture-tight manner, and a perforation aid for perforating the container wall of the cartridge.
A third set for hookahs consists of at least one cartridge, a bowl which is matched to the cartridge, and a perforation aid for perforating the cartridge.
With each of these sets, a perforation aid may already be arranged or formed in the inside of the bowl. This permits the cartridge to be pressed only into the bowl. The container wall is pierced by way of the pressing-in, so that the smoke may escape from the cartridge into the bowl and the smoke tube. The upper side of the cartridge thereby may be closed in a moisture-tight manner with a removable tab, a foil covering or by way of the container wall itself.
The bowl is provided with a sealing shoulder corresponding to the cartridge's outwardly projecting sealing edge. A bowl with such a sealing shoulder has the advantage that a cartridge with the sealing edge may be placed onto this shoulder in a practically airtight manner.
The cartridge 11 represented in
The shape of the lid 15 is designed such that from this, one may tell whether a vacuum, ambient pressure or an overpressure is present in the cartridge. One may take note of the quality of the contents by way of this. The container may be evacuated, in order to increase the shelf-life and to reduce a tendency for the fluid and solid ingredients to demix. The container according to
The cartridge 11 according to
The container wall 13, 15 may however also be already designed in a perforated manner, so that openings no longer need to be introduced. Such a perforation (consisting of premanufactured openings 25), as is represented in
The cartridge shown in
A similar closure tab 29 may also be designed via opening 25 in the shell 13. Such a closure tab 29 is represented in
A further possibility for the closure of the contents of the cartridge 11 is represented in
As shown in
A third cartridge is shown in
The cartridge 11 represented in cross section in
Two bowls 43, 45 which are filled with cartridges 11, are represented in
The shell 13 is pierced by the tips of the perforation insert 47 when pressing the cartridge into the bowl. The smoke which exits through these openings 23 may go through the perforation insert and the sieve, into the funnel-like exit mouth of the bowl, and thereafter through the smoke tube 51 into the glass and the tube of the hookah. The bowl therefore comprises a sealing part 53 which bears on the cartridge 11, and a smoke funnel 55 which is distanced to the shell 13 of the cartridge.
The bowl 45 shown in
With regard to the filled bowl 43 according to
The cartridge does no rest with the shell on the base of the smoke funnel 55, thanks to the sealing edge 59 on the cartridge, and the sealing shoulder 53 on the bowl. For this reason, a space is formed between the smoke funnel 55 and the cartridge shell, into which the smoke may exit from the cartridge and through which it may be drawn into the smoke tube 51.
Two layers of perforated aluminium foil 61 are arranged between the cartridge and the charcoal tablet 63 in the conventional manner, so that the sucked air gets through the openings 25 in the lid 15 into the cartridge 11, also in the region in which a charcoal tablet 63 lies on the cartridge 11.
Such a traditional support of aluminium foil 61 may be omitted, if a structure is embossed into the lid 15, which on the one hand ensures a distance between the tobacco and the glowing charcoal 63, and on the other hand permits an air circulation below the charcoal tablet.
The lid 15 may likewise be designed in a two-layered manner, so that a lower layer of the lid 15 provided with relatively fine openings covers the tobacco, and upper layer provided with larger openings, as a rest surface for the charcoal, is formed at a distance to this lower layer and ensures a distance between the charcoal and the tobacco.
With one advantageous embodiment, as is represented in
This division may be effected from the lid side through the molasses 18 or from the shell side through the tobacco. The lid 15 and the shell 13 may be provided with openings 25 and closure tabs 27, 29 (
The cartridge may also be designed in a paired manner, wherein a first cartridge 11 contains the dry tobacco 16, and a second cartridge 14 the fluid constituents 18 of the hookah tobacco. Such a cartridge pair 11, 14 is shown in each case in
The molasses cartridge 14 forms an air layer which permits a uniform permeation of the moistened tobacco with the sucked air also below a charcoal tablet 63.
