[0002] Technical area

[0003] The invention relates to a water pipe with a base body and with a chimney body having a mouthpiece opening and a reservoir opening opposite the mouthpiece opening, wherein the chimney body is displaceable between a transport position in which the chimney body is at least partially inserted into the base body and a use position in which the chimney body is at least partially pulled out of the base body, and wherein the base body receives a smoking article receptacle projecting into the base body.

[0004] State of the art

[0005] US4116204A discloses a water pipe with a base body from which a chimney body can be telescopically extended. Due to the telescopic design of the chimney body, it can be moved between a transport position, in which the chimney body is inserted into the base body, and a use position, in which the chimney body is extended and removed from the base body. The base body serves as a reservoir for water and accommodates a tubular smoking article holder, the reservoir-side opening of which is located below the water level in the reservoir.Although the length of the hookah can be relatively short in transport position, the necessary tightness of the hookah at the transitions between the telescopic elements, particularly at the transition between the water-holding base body and the telescopic chimney body, imposes restrictions on the choice of materials and also requires a complex connection technology between the base body and chimney body, as leaks would impair the smoking experience. Description of the invention.

[0006] The invention is therefore based on the object of providing a water pipe which, largely independent of the material used for the water pipe, offers a space-saving transport option without impairing the smoking experience due to leaks.

[0007] The invention achieves this objective by providing a reservoir bag that is fluidically connected to the reservoir opening and, in the position of use, is arranged in the base body and forms a passage opening for the smoking article receptacle. As a result of the inventive measures, there is no need for a fluid-tight connection between the chimney body and the base body, since the water reservoir is not formed by the base body, but by a reservoir bag that is fluidly connected to the chimney body, in particular fluid-tightly connected. The base body therefore functions merely as a stand that accommodates the chimney body and, above it, a smoking article receptacle. Advantageously, the filled reservoir bag can rest against the inside of the base body, thereby significantly increasing the stability of the base body.Since there is no need for a fluid-tight connection between the base body and the chimney body, the connection between these two bodies can be designed in a simple manner, for example by the base body enclosing or clamping the chimney body at contact points or contact sections. The length of the hookah is changed by moving the chimney body between a transport position in which the chimney body is at least partially arranged or inserted into the base body, and a use position in which the chimney body is at least partially pulled out of the base body. In the transport position, the reservoir opening of the chimney body is preferably arranged in the foot area of ​​the base body. Arranged or inserted in sections in the base body means that the chimney body does not have to be completely inserted or arranged in the base body, but that an end section of the chimney body can protrude from the base body.Pulled out section by section from the base body means that an end section in the area of ​​the reservoir opening of the chimney body remains in the head area of ​​the base body for connection purposes. The reservoir opening of the chimney body is thus located in the head area of ​​the base body when in use. Neither a positive fit nor a fluid-tight connection between the base and chimney body is necessary, which means that they can be designed independently of each other in terms of material selection. In particular, the base and chimney bodies can be designed such that their volume can be reduced by deformation, allowing the hookah to be reduced not only in the lengthwise direction of the hookah, but also transversely to it. Since the reservoir is formed by a reservoir bag, it can be folded up for compact storage.The reservoir bag can be made of a food-safe material, for example polyethylene (PE), in particular of a film. The reservoir bag is connected to the chimney body in a fluid-tight manner, so that a displacement of the chimney body can also lead to a displacement of the reservoir bag. In the use position, the reservoir bag is arranged in the base body; in the transport position, depending on the design, the reservoir bag can also be arranged in the base body or at least partially outside the base body, on the side opposite the mouth opening of the chimney body. Particularly stable conditions arise when the largest diameter of the reservoir bag is larger than the inner diameter of the base body, so that the filled reservoir bag presses against the inner wall of the base body and can additionally stabilize it.According to the invention, the reservoir bag has a passage opening for the tobacco product holder held by the base body, thus providing all the necessary features for a smooth smoking experience. The tobacco product holder can, for example, be glued or welded to the reservoir bag.

[0008] If the water pipe is to be used for smoking while in the transport position, the chimney body is first pulled out of the base body and placed in the use position. The reservoir bag is then filled with water via the mouthpiece opening of the chimney body, whereby the water must be filled to a level above the reservoir-side opening of the smoking article holder. A smoking article is then placed in the smoking article holder and lit. By applying negative pressure by suction at the mouthpiece opening of the chimney body, the smoke produced by the burning smoking article is passed through the smoking article holder through the water in the reservoir bag, after which the smoke enters the chimney body through the reservoir opening and can be consumed. After smoking, the smoking article can be removed, the reservoir bag emptied, and the chimney body moved into the transport position.

[0009] A simple, fluid-tight flow connection between the reservoir bag and the chimney body is achieved when the reservoir bag includes an end section in the area of ​​the chimney body's reservoir opening and is glued or welded to the outside of the chimney body. A sealing tape can be used as an adhesive. Naturally, the reservoir bag can also be attached to the inside of the chimney body.

[0010] In order to enable the hookah to be held securely during use, it is proposed that the chimney body have at least one locking connection on the reservoir opening side, which secures the chimney body in its position of use. The locking connection can be one or more locking hooks that are positioned against the base body. Alternatively, the chimney body can form one or more locking receptacles into which one or more locking hooks of the base body engage. In order to make it more difficult for the chimney body to become detached from the base body due to tensile force, the reservoir bag that surrounds the end section of the chimney body can form a thickened portion in the area of ​​the reservoir opening, so that the chimney body has an outer diameter in this area that is larger than the inner diameter of the opening of the base body at its end section facing the chimney body.Another way to secure the chimney body in its operating position is to clamp the chimney body to the base body in its operating position and / or to screw the chimney body into the base body in its operating position. Securing by screwing it in can be achieved using a threaded connection. The chimney body can also be secured to the base body with a bayonet lock.

[0011] To further improve the compactness of the water pipe without compromising the tightness of the reservoir bag, the smoking article receptacle can form a sleeve piece protruding into the reservoir bag and a sleeve piece arranged outside the reservoir bag and enclosing the sleeve piece. The sleeve piece and the sleeve piece accommodate a reservoir bag section surrounding the passage opening, preferably with a sealing ring interposed between them. As a result of this measure, the smoke from the smoking article can be introduced into the reservoir bag with minimal loss. The sleeve piece and the sleeve piece are preferably pressed together. The sleeve piece can form a smoking article reservoir or serve as a receptacle for a detachable, insertable smoking article reservoir.The latter provides the advantage that after smoking, the sleeve and socket pieces can be compactly stored together with the reservoir bag in the base body when they are pressed through the base body's receptacle, while the smoking material reservoir, which contains a glowing ember, can be stored separately without the risk of damaging the reservoir bag. The smoking material reservoir can have a clip for attaching it to the outside of the base body.

[0012] In order to obtain a particularly space-saving hookah, it is recommended in a preferred embodiment of the hookah according to the invention that the chimney body and / or the base body each have at least one bending edge running essentially in the hookah's longitudinal direction for folding purposes. This makes the hookah not only short but also particularly flat when transported. In particular, if at least two bending edges running essentially in the hookah's longitudinal direction are provided, the chimney body and / or the base body can be folded into a single plane. Favorable folding conditions arise when the at least two bending edges lie opposite one another when the chimney body and / or the base body are unfolded. An even more compact hookah results when the chimney body has at least one bending edge running essentially transversely to the hookah's longitudinal direction.In particular, the bending edge running transversely to the hookah's longitudinal direction can be located at the level of the opening of the base body at its end section facing the chimney body when the chimney body is in the transport position, so that the protruding part not inserted into the base body can be folded in. The length of the hookah in the transport position is thus essentially determined by the length of the base body.

[0013] Easy folding and, at the same time, favorable production conditions result when the chimney body and / or the base body are made of, preferably coated, cardboard. This material selection is possible because the base body itself does not come into contact with water and serves only as a structural basis. The chimney body only comes into contact with water briefly when filling the reservoir bag, whereas cardboard is generally resistant to moderate contact. A significant increase in resistance, however, results when the cardboard is coated on the inside, i.e. the side that comes into contact with the smoke. The coating is preferably a food-safe coating. Preferably, the coating comprises polyethylene. The cardboard can also be coated on both sides.Despite the cardboard design of the base body, it still offers a stable stand, especially because the water-filled reservoir bag presses against the inner wall of the base body and thus protects it from accidental folding.

[0014] A stable yet easy-to-fold chimney body is created when the chimney body has a polygonal cross-section when unfolded. For example, the cross-section can be hexagonal, resulting in six bending edges running along the length of the hookah.

[0015] The base body can form a truncated pyramid with a polygonal base. This creates a stable base despite being easily foldable. The cross-section can be hexagonal or heptagonal, for example, resulting in six or seven bending edges. Due to the pyramid-shaped design of the base body, its bending edges do not run axially parallel to the hookah's longitudinal axis, but rather essentially in the hookah's longitudinal direction. A bending edge that runs essentially in the hookah's longitudinal direction is therefore to be understood as a bending edge that allows the shell of the base body to be folded around a hookah's longitudinal axis.

[0016] Chimney bodies according to the invention can be designed in different lengths and diameters. The chimney body for a water pipe has a mouthpiece opening and a reservoir opening located opposite the mouthpiece opening, wherein the reservoir opening is fluidly connected to a reservoir bag, which forms a passage opening for a smoking article receptacle. In particular, the chimney body comprises at least one bending edge extending substantially in the longitudinal direction of the chimney body and / or at least one bending edge extending substantially transversely to the longitudinal direction of the chimney body and is preferably made of cardboard.

[0023] Ways to implement the invention

[0024] A water pipe according to the invention has, as can be seen from Fig. 1, for example, a base body 1 and a chimney body 2. The chimney body 2 comprises a mouthpiece opening 3 and an opposite reservoir opening 4. The chimney body 2 is arranged so as to be displaceable between a use position 5 shown in Fig. 1, in which the chimney body 2 is at least partially pulled out of the base body 1, and a transport position 6 shown in Figs. 2 and 3, in which the chimney body 2 is at least partially arranged in the base body 1. It can be seen from Fig. 1 that the chimney body 2 is also arranged in the area of ​​the reservoir opening 4 in the base body 1 in the pulled-out use position 5. The chimney body 2 is therefore partially pulled out of the base body 1. The base body 1 accommodates a smoking article receptacle 7 which projects into the interior of the base body 1.According to the invention, the chimney body 2, namely its reservoir opening 4, is fluidly connected, in particular fluid-tightly connected, to a reservoir bag 8. The reservoir bag 8 has a passage opening 9 for the smoking article receptacle 7. According to the invention, the particularly flexible reservoir bag 8 forms the water reservoir of the hookah and not the base body 1. According to Fig. 1, the reservoir bag 8 is arranged completely within the base body 1 in the use position 5. According to Fig. 2, the reservoir bag 8 can lie partially outside the base body 1 in the transport position 6.

[0025] The chimney body 2 can have at least one locking connection on the reservoir opening side

[0026] 9, as can be seen from Fig. 1 and in particular Fig. 4. Several locking connections 9 can be provided circumferentially in the region of the reservoir opening 4. In addition, the chimney body 2 can be secured against tensile force by a reservoir bag-related thickening 10, for example, formed by a sealing strip.

[0027] The smoking article receptacle 7 can be constructed in multiple pieces. It can comprise a sleeve piece 11 extending into the reservoir bag 8 and a sleeve piece 12 arranged outside the reservoir bag 8. The sleeve piece 12 encompasses the portion of the sleeve piece 11 extending from the reservoir bag. The sleeve piece 12 and the sleeve piece 11 thereby clamp a reservoir bag portion surrounding the passage opening 9. To improve the seal, a sealing ring 13 can be provided between the sleeve piece 12 and the sleeve piece 11 on the outside of the reservoir bag. The smoking article receptacle 7 can comprise a further part, namely a smoking article reservoir 14, which can be inserted into the sleeve piece 12. As a result, the sleeve piece 12 and the socket piece 11 can be arranged at least partially within the base body 1 in the transport position and the smoking article reservoir 14 with any remaining embers can be stored separately from the reservoir bag 8.The tobacco product reservoir 14 can be attached to a base body wall by means of a clamp 15. The clamp 15 can simultaneously form a sieve, particularly a metallic sieve, for the tobacco product reservoir 14 (Fig. 2 and Fig. 3).

[0028] In particular, it can be seen from Fig. 3 that the chimney body 2 and the base body 1 each have bending edges 17 running essentially in the longitudinal direction 16 of the hookah, whereby the chimney body 2 and the base body 1 can be folded together. The chimney body 2 can also have bending edges 17 running transversely to the longitudinal direction 16 of the hookah, whereby the chimney body can be additionally folded in to reduce its length. The bending edges 17 running transversely to the longitudinal direction 16 of the hookah can be arranged at the level of the opening of the base body 1 at its end section facing the chimney body 2 when the chimney body 1 is in the transport position 6, whereby the protruding part of the chimney body 2 that has not been inserted into the base body 1 can be folded in (Fig. 2 and Fig. 3).

[0029] The chimney body 2 and the base body 1 can be made of cardboard. For this purpose, the cutting patterns of the cardboard blanks shown in Fig. 5 and Fig. 6 can be used, which are folded along their bending edges 17 running in the longitudinal direction 16 of the hookah and glued together via a flap 18 to form a solid body. The chimney body 2 can preferably comprise coated mouthpiece flaps 19, which are folded inward so that the resulting mouthpiece opening 3 has rounded edges. This not only results in a pleasant haptic feeling, but also has the advantage that any saliva does not come into contact with the uncoated cardboard edge piece. As disclosed in Fig. 4, the foldable design and in particular the material selection allow the chimney body 2 and base body 1 to be designed with a polygonal cross-section.To increase stability, the base body 1 can form a truncated pyramid with an open, polygonal base. The base body 1 can engage around the chimney body 2 in sections in a form-fitting manner, i.e., have the same polygonal shape in cross-section in sections. However, advantageous stability conditions for the smoking article holder 7 arise if the base body 1 has a holder 22 for the smoking article holder 7 that runs along a bent edge 17, resulting in a three-dimensional holder 22 that secures the smoking article holder against tipping. This can be achieved by providing an additional polygonal edge. The base body 1 can thus have a polygonal cross-section that has one more corner than the polygonal cross-section of the chimney body 2.

[0030] The chimney body 2 can have a through-hole 20 that can be closed with a finger. The base body 1 can include fill level indicators 21 with which the fill level 23 in the reservoir bag 8 can be read.
