description
[001] The present invention relates to a container for receiving fuel and / or working fluid for vehicles, especially for utility vehicles, with a filling tube for receiving a supply gun according to the invention and embodiments.
[002] In addition, the invention encompasses a fuel tank for utility vehicles with at least a first receiving compartment for fuel and a second receiving compartment for a second fuel or a working fluid or a working fluid component according to the invention. .
[003] Furthermore, the invention encompasses a process for producing a container for working fluids and / or fuels for utility vehicles according to the embodiment and invention.
[004] A container of this kind for receiving fuel and / or service fluid has become known from European Patent EP 1 502 794 A2.
[005] The use of urea, namely AdBlue, is intended for the operation of utility vehicles operated with diesel fuel to reduce soot. Urea is usually conducted in the vehicle in a separate tank. In order to avoid incorrect filling of the tanks foreseen for fuels, receiving urea, it is common to provide the supply pistol with the special closing mechanism. For its activation, the urea tank has a separate insert in the filling tube that has a ring magnet on its wall. A supply gun suitable for profiling the internal shape of the insertion part must be inserted to such an extent inside the filling tube and in the insertion part integrated there that the ring magnet surrounds the supply gun in a region where the mechanism is mounted. closing valve on the supply gun. The closing mechanism on the supply gun will be opened exclusively by the action of the ring magnet and also released. In this way, erroneous supplies of urea in fluid tanks that do not have an insert allocated with a ring magnet must be safely avoided. Conversely, erroneous refueling of urea tanks with fuel must be avoided because the insert requires a certain profile for the supply gun, that is, for the tip of this gun, so that the fuel supply guns do not fit in the insert that is provided in the urea tanks.
[006] A solution of this nature also became known from the publication of this species, that is, from the European patent EP 1 502 794 A2.Other that is supplied according to the publication of this species is made of plastic. In this case, the plastic tank has, in the region of its filling opening, a tank with a neck shoulder. The tank sleeve is attached to the supply as a support for a closing cap. In addition, an insert for the incorrect supply of the tank is attached to the tank sleeve, which contains a ring magnet on its wall. This erroneous supply insert will be joined with the tank sleeve by the fact that the erroneous supply insert is attached to a neck piece, which serves as a retainer, which is supported with a surrounding flange on the upper edge of the tank sleeve and projects into it. In this case, the flange will be screwed using screws with the upper edge of the tank sleeve. The neck piece to which the wrong supply insert is attached is also used to fix the filling tube with the closing cap. Fixing is also done by spot welding.
[007] A complex constitution constituting a disadvantage in the European Patent EP 1 502 794A2, which provides for many components and the high costs resulting from production and assembly.
[008] From the document DE 2 0 2005 011 575 U1, a filling tube for a plastic container is known to prevent a wrong supply of the container. The filling tube can be closed with a closing cap. In the filling tube, a plastic support for a permanent magnet must be inserted. In this case, it is provided that the plastic support that receives the permanent magnet is directly connected with the liquid-tight filling tube. This should ensure that only a single element with the permanent magnet is integrated into the filling tube, which, together with the filling tube, enables a liquid-tight integration of the permanent magnet.
[009] By the solution presented in document DE 2 0 2005 011575 U1 - compared to the solution according to the European patent EP 1 502 794 A2 - the necessary components are reduced, however, a relatively high construction effort is still necessary. In addition, the filling tube - in a manner not described in more detail in DE 2 0 2005 011 575 U1 - will have to be mounted in a plastic container, preferably being welded.
[010] The task of the present invention lies in creating a container that is able to act under a closing mechanism of a supply gun and that can be produced in a simple way and with few assembly components.
[011] In addition, the present invention aims to create a simple and cost-effective process for the production of a container to receive fuel and / or working fluids
[012] The task according to the invention will be solved - in relation to the container to be created - according to the invention and embodiment.
[013] The task according to the invention will be solved - in relation to the process to be created - according to the embodiments.
[014] Due to the fact that the container, according to the embodiment, is made of plastic with a support of the filling tube that is integrally shaped with the container, being that this support is integrated by contraction to the filling tube and in view of the fact that the filling tube forms an annular compartment in which the loss-proof magnet is integrated, a container is created which can be produced at an advantageous cost and with process safety and which is suitable for opening the closing mechanism of a supply gun, that is, in which a supply in the wrong tank will be largely suppressed. In comparison with the state of the art, the necessary components will be further reduced. By contraction of the filler tube in the filler tube container, complex screwing and soldering can be dispensed with as proposed, for example, in European patent EP 1 502 794 A2. A connection of the filling tube with the contraction filling tube holder also has the advantage that a dense and loadable connection can be created, especially a liquid-tight connection, between the filling tube and the filling tube support.
[015] Due to the solid conformation of the filler tube support with the container, an additional component will be dispensed.
[016] The filling tube that is contracted inside the support of the filling tube serves on the one hand to receive a supply gun and on the other hand to receive a magnet, by which the supply gun can be released. With an internal diameter and / or an adequate profile of the filling tube, it can be prevented that pistols supplying liquids that are not to be filled into the container, fit inside the filling tube.
[017] In the container according to the invention it can preferably be provided that it is a container for receiving urea or AdBlues. Supply pistols for such fuels normally have a smaller diameter than supply pistols for conventional fuel supply, for example, for diesel supply.
[018] The production of the plastic container with the support of the solid filling tube can be carried out according to already known processes. The inventors recognized in this process that the contraction, generally in 3% of the plastic container after its production can be used so that a filling tube is introduced by contraction in the support of the filling tube, that is, the filling tube will be introduced in the filler tube holder before the filler tube holder is already cooled to a temperature for later use. Preferably, the filler tube will be introduced into the filler tube holder at a time when the temperature of the filler tube holder is still the highest possible.
[019] The filling tube can be pressed into a state in the tube holder which is still hot. Preferably, the connection will be made in which the filling tube and the filling tube support without an additional connection technique, that is, without additional connection means.
[020] The filling tube may be formed of random material, for example, metal plastic, especially steel or aluminum. A conformation of the support of the filling tube of a synthetic material, ie plastic, is specially adapted. The production can preferably be done in an injection molding process.
[021] Alternatively or in addition, the introduction of the filler tube into the filler tube holder before cooling the filler tube holder from a "manufacturing temperature" to a later service temperature, it may also be provided that the tube filler is introduced in a cooled state, that is, in a state in which the filler tube is markedly cooler than the filler tube support. Due to the fact that the filling tube then heats up, it starts to expand, with which a contraction in the support of the filling tube can be achieved, that is, it can be at least reinforced.
[022] This process is feasible regardless of the material selection of the filling tube, but it is specially adapted when it comes to a plastic filling tube.
[023] In its outer circumference, especially in those areas that contact an inner wall of the filling tube support, the filling tube may have an adequate structure. The inventor recognized that it can be advantageous when the available contact face between the outer circumference of the filling tube and the inner wall of the filling tube support is not contracted by the contraction process, however, that faces of contact points for contraction. In this sense, it can be foreseen that in its external circumference, the filling tube has at least one projection, that is, a ring-shaped surrounding rib that can be integrated by contraction in the inner wall of the filling tube support, that is, be contracted. An annular, surrounding protrusion, that is, a surrounding annular rib, can be contracted based on the reduced contact face, particularly advantageously on the inner wall of the filling tube support. In this way, tolerances or other deviations can be compensated. An annular and surrounding conformation projection is indicated by the fact that this way it will be reliably ensured that the outer circumference of the filling tube is joined, that is, sealed with the inner wall of the completely liquid-tight filling tube support. . This will be especially advantageous when it is provided, according to the invention, to screw a cap on the filling tube in order to close the filling opening, that is, this cap would be fitted on the filling tube. Tapering a cap on the filler tube holder is disadvantageous because the filler tube holder cannot be simply as accurately as this is possible, for example, by injection molding in the case of the filler tube. For this reason, it should be preferred to close the filling opening because the closing cap is suitable for the filling tube.
[024] In its production, the filling tube will already be able to receive an internal or external thread in which the closing cap can be screwed. In an alternative or complementary way, it can also be provided that the filling tube already has a seal, preferably a 0 ring, or similar unit.
[025] It is advantageous that the filling tube preferably has at least three annular protrusions (ribs) that project preferably in a convergent direction in a parallel plane, being contracted in the inner wall of the filling tube support, that is, they meet contracted there. In this way, a fail-safe and reliable connection between the fill tube and the fill tube holder will be achieved. In addition, due to the variety of ring-shaped projections, a particularly tight connection will also be made between the filling tube and the filling tube support. This is especially important when the closure cap is placed on the filling tube because in this case it must be avoided that liquid can flow between the filling tube and the support of the filling tube.
[026] Reinforcing rods can be projected between the ring-shaped protrusions, which preferably project axially towards the filling tube.
[027] According to the invention it can also be provided that the inner diameter of the filler tube support, at least in the region where the filler tube is provided, narrows downwards towards the inner compartment of the container. This is also the way to achieve an especially good connection between the filler tube and the filler tube holder, especially when the filler tube has a shape that corresponds at least approximately to the inner diameter that narrows from the filler tube holder .
[028] It is advantageous when the ring compartment for receiving the magnet is opened in a downward direction towards the inner compartment of the container.
[029] The magnet can be positioned in such a way that it surrounds a supply gun when it is correctly inserted into the filling tube.
[030] A loss-proof magnet arrangement of the compartment can be achieved by different measures, for example, by stapling, fitting, binding, forced introduction, welding or gluing. It should be especially preferred that at least one wall surrounding the annular compartment is provided, having at least partially protruding protrusions, locking elements or similar units that can be positioned under the magnet after it has been inserted from below into the annular compartment. In this case, it can be foreseen that the wall provided with the coupling or similar unit, in the insertion of the magnet may deviate radially towards the outside and, after the introduction of the magnet, it may return - preferably in an elastic way - again to the original position.
[031] It is also possible to fix the magnet with an additional component, for example, a washer or similar unit inside the annular compartment.
[032] It is advantageous that the support of the filling tube has at least one stage of narrowing and / or at least one projection of such a shape that the stage of narrowing and / or the projection are below the annular compartment when the filling tube is inserted into the filling tube holder. This narrowing stage and / or the protrusion may, in this case, reduce the free and available internal diameter in the filler tube support in such a way, this reduction being at least in a partial region, that the inner diameter of the filler tube support is less than the outside diameter of the magnet.
[033] The inventors recognized that with a conformation of this type, it is possible to avoid a simple and cost-effective way that the ring magnet - if it leaves the ring compartment unintentionally - falls into the internal compartment of the plastic container where it may eventually cause damage .
[034] The narrowing stage, that is, the protrusion to reduce the inner diameter of the filler tube support does not need to be shaped in a surrounding manner, but it may be sufficient for the filler tube to have a protrusion. , a cam, cam or similar unit that ensures that the magnet cannot fall into the inner compartment of the plastic container.
[035] It may also be advantageous for the filling tube support to have a terminal stop on its internal wall, on which a support face of the filling tube rests when the filling tube is placed in the axial position provided for inside the filling tube support. filling. The end stop may in this case, for example, be shaped as a surrounding step. In addition, it can be provided that the support face of the filling tube, which rests on the end stop, is provided by the underside of the lower annular protrusion, that is, the lower annular rib. The end stop in combination with the support face of the filling tube ensures that the filling tube can be positioned precisely in the desired position within the support of the filling tube.
[036] It is advantageous when the walls of the annular compartment surrounding the magnet are formed cracks, notches, channels or cuts. In this way, the magnet can be bathed in a liquid introduced into the container. This modality is also adapted to introduce the magnet in a particularly simple way inside the annular compartment because the cracks, notches, channels or cuts reinforce the radial deviation, that is, elastic, of the annular compartment wall. In addition, this conformation helps to compensate for possible manufacturing tolerances that could eventually be reinforced by the fact that the container according to the invention, in later practical use, is exposed to different temperatures. According to the invention, it can be provided, in this case, that the cracks, notches, channels or cuts are so provided that the ring magnet can be bathed on its internal side (internal circular face) and on its external side (circular face) external).
[037] To prevent the magnet from being attacked by the liquid received in the plastic container, it can be provided that the magnet is coated with a layer of epoxy resin. Alternatively, another shape of the magnet can be selected, especially resistant to urea. The magnet can also be integrated by sintering into a plastic component, that is, it can be bathed in plastic.
[038] In another embodiment of the invention, it may be envisaged that the magnet be formed as a permanent magnet or as a magnetizable element or magnetizable plastic. The inventors have recognized that also a magnetized element or a magnetizable element can be used instead of a permanent magnet hitherto conventional.
[039] Preferably, the magnet is a ring magnet.
[040] Ring magnets can be, for example, a product that is marketed under the Elafix® brand.
[041] The filling tube can be formed in one piece or in several sections. It is recommended to shape the filling tube in one piece. However, one can also imagine that the filling tube is formed in at least two sessions, for example, to ensure that that part of the filling tube that receives the magnet is not joined with the part of the filling tube that receives the closing cap, that is, the component that produces the sealing union between the inner wall of the filler tube support and the outer circumference of the filler tube.
[042] In an alternative or complementary way to a filling tube with surrounding protrusions or annular ribs and with a sealing action, it can also be foreseen that the filling tube will be contracted only in points by counter-hooks, or similar units within the filling tube support. In this case, it may be necessary for the filling opening closing cap to be applied to the filling tube support, for example, by screwing.
[043] The plastic container can be produced, for example, by sintering, especially rotary sintering, as well as by a blowing technique.
[044] In the case of plastic, from which the plastic container is produced, it can be, for example, polyurethane, polyamide, polypropylene or polyethylene. As plastic for the production of the filling tube, polyamide, polyurethane, polyethylene or polypropylene may also be used.
[045] It can be provided according to the invention that the plastic container is part of a utility vehicle tank. In this case, it may also be provided that the plastic container constitutes the internal compartment of a utility vehicle tank.
[046] The plastic container can be produced by sintering, preferably rotary sintering, in an outer metallic film of a utility vehicle tank. This is particularly suitable because, for example, urea would attack the outer metallic film. Because the plastic container is produced in a rotary sintering process on the outer metallic foil, a particularly advantageous cost measure is selected because the outer metallic foil of the utility vehicle tank forms the tool.
[047] According to the invention, it may also be provided that the plastic container is formed as a plastic coating, that is, with the internal plastic coating of a utility vehicle tank - preferably produced in a rotary sintering process. This prevents the outer metallic film from being attacked by possibly aggressive fuel. At the same time, the location available inside the outer metallic film will be used in an optimal way. The sintered layer of a synthetic material that forms the plastic container it can preferably be applied in a thin layer on the inner wall of the outer metallic film. The sintered layer of plastic can preferably be produced by the fact that the outer film - after unmolding - is heated as a whole and then introduced as plastic powder into the internal compartment. The plastic powder melts on the hot inner wall and thus forms the plastic sintered layer.
[048] The metallic outer film achieves a high degree of rigidity without the need for large wall thicknesses.
[049] For the production of the sintered plastic layer, the synthetic materials already mentioned, such as polyurethane, such as polyamide, polypropylene or polyethylene, are adapted. Through these synthetic materials thin wall thicknesses can be produced, but they still meet the desired requirements, that is, especially the necessary chemical inertia in relation to the fuels to be transported.
[050] It may be advantageous for the plastic to adhere to the inner side of the metallic outer film. The synthetic material can be produced with a property by which adherence is achieved. Eventually, it may be envisaged that the synthetic material will be reinforced by carbon fibers, or a similar material. Alternatively, other reinforcement linings may also be provided.
[051] Through an adequate conformation of the inlet opening in the external metallic film, it may - possibly with the aid of an additional tool - be able to achieve that the sintered layer of synthetic material according to the support of the filling tube, which is shaped in one way with the fuel container, this support in which, before cooling, the filling tube will be inserted.
[052] The filling tube can be pressed into the body, that is, the support of the filling tube and then there it is applied by the process of contraction of the rotational body, that is, of the support of the filling tube. If necessary, sealing rings and similar units can also be inserted in the case and can - by contraction - be positioned in such a way between the filling tube and the filling tube support that a liquid-tight connection is formed between the parts.
[053] The outer metallic film can, for example, be produced from aluminum or an aluminum alloy. In this case, of course, another metal is also considered, for example, steel, noble steel or a corresponding alloy.
[054] The solution according to the present invention also makes it possible to produce integrated multiple containers, especially double containers, within a support structure, that is, in a common metallic outer film. The integration of the containers within a common carrier structure may have the advantage that not all the partial container needs to be fixed, specifically, by two or more consoles in the vehicle frame, but that the integrated container can be mounted as a unit with others containers with only two consoles in a vehicle frame.
[055] According to the invention, a fuel tank for commercial vehicles can be provided that at least has a first integration compartment for fuel and a second integration compartment for a second fuel or a working fluid or a fluid component. job. It may be provided, in this case, that the second receiving container is formed by the plastic container itself, as described above. In this case, the container that forms the second integration or receiver compartment can be joined with the first receiver compartment to compose a unit.
[056] The first receiving compartment, which can be provided to receive a conventional fuel, does not require a layer of plastic sintering on the inside and, therefore, can be produced in a known way at an advantageous cost. The union with the container that makes up the second receiving compartment may preferably be made by the fact that the front ends of the circumferential walls, which make up the first and the second receiving compartment, are reciprocally welded or interconnected in another way and manner. To this end, state-of-the-art solutions are already known.
[057] In the process according to the present invention according to the embodiment to produce a container for fuels and / or working fluids for commercial vehicles, an external metallic film, which forms an essentially closed internal compartment, is initially expected to be heated . In the internal compartment - preferably by the height of entry for the liquid to be subsequently introduced into the internal container - a plastic, preferably a plastic powder, will be filled. In this case, the plastic material forms a plastic sintering layer on the inner face of the metallic outer film. The plastic sintering layer transfixes in the case, according to the invention, the inlet opening in the external metallic film in order to form a support for the filling tube there. For this purpose, additional suitable tools can be applied to the inlet opening, in the external metallic film, which ensure that the filling tube support receives the desired shape. Before the sintered plastic layer cools, a filling tube will be inserted into the filler tube support, which, with the cooling of the filler tube support contracted there. In this case, the filling tube is so shaped that it forms an annular compartment in which a ring magnet is integrated, loss-proof.
[058] The embodiment presents an alternative container in relation to the invention. The container according to the embodiment is shaped to receive fuel and / or working fluid for vehicles, especially utility vehicles. For this, the container has a filling tube to receive a supply gun. The filling tube has a magnet to act on a closing mechanism of a supply gun. Due to the fact that the container has an external metallic film with an opening to receive a support for the filling tube, and due to the fact that by a process of rotation inside the external metallic film, a container of synthetic material is formed, that is, a plastic sintering coating on the inner wall of the outer metallic film, in a way that results in a cost-effective container that can also be produced with process safety. According to the invention, according to the embodiment, by means of the rotary sintering process, the support of the filling tube introduced into the opening must be joined with the plastic container, that is, with the sintered plastic coating. In addition, in the support of the filling tube, a filling tube is contracted, which is shaped to receive a supply gun and which form an annular compartment, in which the magnet is integrated loss-proof.
[059] In comparison with the state of the art, the solution according to the invention presents a simple and safe possibility of attaching a support of the filling tube in a container. The components then required will be reduced because the connection of the filler tube support is carried out by the rotary sintering process. Complex screwing or welding of the filler tube support may be dispensed with. The connection produced by the contraction between the filling tube and the support of the filling tube can also be made in a simple way and at an advantageous cost, as already described, for example, with respect to the solution according to the invention, according to the invention.
[060] The advantages apply in a similar way also to the container according to the embodiment, with the difference that the support of the filling tube is not formed integrally of synthetic material with the container, however, it is shaped like a separate component. A loss-proof, ie stable, connection of the filler tube holder to the plastic material of the container can preferably be made by the fact that the filler tube holder is inserted into an inlet opening and an outer metallic film , and is also sintered in a rotary sintering process with which at the same time a plastic container is produced within the metallic outer film. Preferably, the filler tube support will be positioned in such a way in the inlet opening of the outer metallic film that a part of the filler tube holder protrudes outwards above the outer metallic film. An especially good connection of the filler tube support with the plastic material that forms the plastic container results when the filler tube support has at least partially a notch, a groove, a recess, or the like, into which the plastic can penetrate during the sintering process.
[061] The invention encompasses an alternative process in relation to concretization, to produce a container. In the process foreseen in accordance with the embodiment for the production of a container for fuels and / or working fluids for commercial vehicles, it is initially foreseen that an external metallic film, forming an essentially closed internal compartment, is heated. In the internal compartment a synthetic material will be introduced in order to form a layer of plastic - sintered on the inner side of the metallic outer film. The synthetic material is preferably a plastic powder. At the entrance opening in the outer metallic film, a filler tube support will preferably be inserted - before the introduction of the plastic powder. According to the invention, it is provided, in this case, that the plastic sintering layer to be formed connects the support of the filling tube, inserted in the entrance opening of the external metallic film, loss-proof, that is, it also produces its sintering. Before the plastic sintered layer is cooled, a filler tube will be inserted into the filler tube support which, by cooling the filler tube support, will be contracted inside the sleeve. The filling tube is shaped in such a way that it forms an annular compartment, in which a loss-proof annular magnet is integrated.
[062] Preferably, the filling tube will only be integrated into the filling tube holder when it has cooled down again. However, it can also be foreseen that the filling tube is already inserted in the support of the filling tube before the external metallic film is heated, that is, during the sintering process.
[063] With respect to the process according to the embodiment, the same advantages already mentioned apply with respect to the process according to the invention with the difference that the support of the filling tube is not shaped in one way with the layer sintered plastic, however, in the case of the filler tube support it is a separate component that will be joined by the sintering process with the lossless plastic sintered layer. For that, it may be advantageous that the support of the filling tube has corresponding indentations, grooves or notches that allow the penetration of the sintered plastic material.
[064] The aforementioned variants and characteristics in relation to the container and in relation to the process according to the invention are valid, similarly, also for the container according to the embodiment and the process according to the embodiment, with the the only difference is that the support of the filling tube 3 on the one hand can be produced as a separate component and, on the other hand, it can be a component that is formed in one piece with the plastic container.
[065] In all the modalities and variants of the invention, it can be advantageous when the entrance opening provided in the external metallic film, intended to receive a support of the filling tube, has an embossed edge for the internal or external side, that is, an edge which projects internally upward. The advantage of this modality is that the tool to perform the rotary sintering process can be used in a defined way. Generally, it is advantageous that the entrance opening in the metallic film, that is, its edge, is so shaped and profiled that the rotary sintering tool can be applied in a defined way there.
[066] In all modalities and variants it is advantageous that the layer is sintered from plastic, that is, the support of the filling tube, that is, the filling tube is made of polyethylene, preferably with a copolymer, especially with adherent properties.
[067] In all modalities and variants it can be advantageous that the support of the filling tube has only a protrusion, that is, a narrowing stage, that is, a cam, which is shaped in such a way that when the filling tube is introduced into the support of the filling tube, the protrusion, that is, the narrowing step, that is, the cam, is located below the ring magnet annular compartment, and the projection, that is, the narrowing step, that is , the cam, reduce the free inner diameter of the filler tube holder in such a way, at least in a partial region, such that the inner diameter of the filler tube holder is smaller than the outer diameter of the ring magnet.
[068] It will be advantageous that the filling tube has at least one ventilation channel, the end of which is directed towards the inner compartment of the container, is at least partially covered by the narrowing step of the filling tube support, with the narrowing stage being arranged at reduced axial distance below the end of the ventilation duct.
[069] It is advantageous that the filling tube has two or more ventilation channels and the filling tube support has a narrowing step that covers at least partially the closed ventilation channel, that is, reached by the liquid level that increases in the inner compartment of the container.
[070] It is advantageous that the ventilation channels project essentially in the axial direction of the filling tube.
[071] The ventilation openings - considered in section - may preferably present an arcuate circle shape.
[072] It has been shown to be especially advantageous that the protrusions, that is, the narrowing steps, that is, the cams, of the filler tube support are arranged axially below the ventilation channels, so that these ventilation channels are covered up towards the tank, at least partially, by the respective projection, that is, the narrowing step, that is, the cam. In this way, the danger that urea may leak out of the tank will be reduced. The narrowing step forms an axially spaced bottom and is provided below the ventilation channel.
[073] It is advantageous that the narrowing stage has a surface aligned on the end of the ventilation channel, the surface being provided with axial distance below the ventilation channel and the surface at least approximately suitable for the transverse face of the front end of the ventilation channel, covering at least approximately the entire ventilation channel axially towards the internal compartment.
[074] In a preferred embodiment, in which the support of the filling tube has only one protrusion, that is, a narrowing step, that is, a cam, it can be predicted that it will be so aligned with a ventilation channel in the filling tube that the ventilation channel - towards the internal compartment of the tank - is essentially covered by the protrusion, that is, by the narrowing step, that is, by said cam. In this case, the narrowing step has an axial distance from the end of the ventilation channel. It is advantageous, in this case, that the filler tube support and the filler tube are positioned in such a way in the inlet opening in the outer metallic wall that the ventilation tube of the filler tube, which is in the highest position, is covered by the narrowing step, that is, the protrusion, that is, the cam. It was evidenced that the danger of abandoning urea from a ventilation channel in the form of nozzles is greater in the ventilation channel whose end, facing towards the interior of the tank, is finally reached by the increasing level of liquid inside the tank. Therefore, it is advantageous that this ventilation channel cannot be transfixed in a straight line, however, it is covered in such a way by the protrusion, that is, by the narrowing step or by the cam, that the urea cannot be ejected in a straight way.
[075] It is advantageous that the narrowing stage receives a ventilation hole that produces a connection between the ventilation channel and a ventilation compartment that is located above the end on the side of the inner compartment of the filling tube support.
[076] The ventilation hole forms a connection between the ventilation duct and a ventilated compartment that is formed when the liquid level in the urea container has fully closed at the opening of the filling tube support, facing towards the inside of the tank. .
[077] Advantageous embodiments of the invention result from the embodiments. Then, based on the drawing, an example of the implementation of the invention is presented in principle.

[0100] The plastic container 1 according to the invention is formed in the example as a plastic coating, that is, an internal plastic coating of a metallic outer film 2 of a utility vehicle tank. However, the invention is of course not restricted to this condition, and the plastic container 1 according to the invention can also be produced without external metallic film. In addition, in the embodiment according to figure 11 it is provided that the plastic container 1 according to the invention offers a second receiving compartment for a fuel tank. Also in this direction, the solution of this invention is not restricted. The plastic container according to the invention can also be produced as a single container, that is, an individual container, which is eventually provided with a metallic outer film.
[0101] The modalities presented below, that is, the different characteristics according to the invention apply to all imaginable plastic containers, regardless of their concrete production and also regardless of whether the plastic container has a metallic outer film or if the Plastic container is produced as a single tank or as a partial container for a larger fuel tank, containing several partial containers.
[0102] Figures 1, 2, 8 and 9 show a cutout of a plastic container 1 to receive a working fluid, in the example of making a urea, that is, an AdBlues for utility vehicle. The plastic container 1 is shaped like a thin coating of an outer metallic film 2 of a utility vehicle tank. The production of the inner lining on the inner side of the outer metallic film 2 can be carried out in different processes, and in the execution example, the inner lining is done by a rotary sintering process.
[0103] In the execution example, the inner plastic lining will hereinafter be referred to as plastic container 1.
[0104] As can be seen in figures 1, 2, 8 and 9, the plastic container 1 has a filling tube 3 with it formed in one way. The filler tube support 3 extends, in this case, through an inlet opening 2a in the outer metallic film 2.
[0105] The outer metallic film 2 that surrounds the plastic container 1, in the execution example is presented as being made of aluminum or an aluminum alloy.
[0106] As can be seen in figures 8 and 9, a filling tube 4 is contracted in the filling tube holder 3, not shown in more detail in figures 3 to 7. The filling tube 4 is retained in the filling tube support 3 only by contraction without additional measures, that is, without additional connection techniques or connection links. The filling tube 4 is used to receive a supply gun 5 which is shown in principle in figure 11. The internal diameter of the filling tube 4, in the example of the execution, is adapted to the conventional external diameter of a supply gun 4 for urea.
[0107] The filling tube 4 - as can be seen especially in figures 6 to 9, have an annular compartment 6, that is, a receiving compartment of a magnet 7. The magnet 7 serves to communicate an incorrect supply and is such positioned way that involves the supply gun 5 when it is inserted, in the conventional way, in the filling tube 4. In this case, the magnet 7 acts in such a way on the supply gun 5 that its closing mechanism will be opened and then filling of the plastic container is possible 1. In the embodiment example, magnet 7 is shaped like a ring magnet. Ring magnet 7 in the execution example is coated with a layer of epoxy resin so that this urea is resistant.
[0108] The contraction connection between the filler tube 4 and the support of the filler tube 3 is carried out in such a way in the execution example that the filler tube 4 is inserted in the support of the filler tube 3, that is, there it will be introduced before the filling tube support 3, after its profiling process, has cooled. The filling tube 4 will therefore be inserted into the filling tube support 3 when it is still hot.
[0109] In the execution example, it may be provided in addition that the filling tube is or will be introduced in a cooled state in the support of the filling tube 3.
[0110] It is provided that in the execution example, the filling tube 4 is made of a plastic material. In addition, it is provided in the execution example, that the filling tube 4 is produced as an injection molding piece.
[0111] In the execution example, ring magnet 7 is formed as a permanent magnet.
[0112] In the execution example, it is provided that the ring compartment 6 is open in a downward direction, towards the inner compartment of the container 1.
[0113] The fixation of the ring magnet 7 in the ring compartment 6 can be seen in the example of execution due to the fact that an outer wall 8 of the ring compartment 6 is provided on its underside, in a surrounding manner, with a projection 9 that protrudes inside the annular compartment 6, that is, when the annular magnet 7 is inserted in the annular compartment 6, it is placed below the annular magnet 7. The surrounding protrusion 9 in the form of a hook hook reduces, in this case, the distance in relation to an internal wall 10 of the annular compartment 6 in such a way that the distance is less than the thickness of the annular magnet 7.
[0114] In the execution example, the ring compartment 6 and ring magnet 7 are so reciprocally adjusted that the ring magnet 7 is trapped between the outer wall 8 and the inner wall 10.
[0115] It can be seen especially from figure 5 that the outer wall 8 of the annular compartment 6 in the execution example has slits 11 that allow the ring magnet 7 to be retained inside the annular compartment 6 with a suitable prestressing. Slits 11 also make it possible, in this case, that tolerances - for example, resulting from production deviations, that is, temperature fluctuations - can be neutralized in the subsequent use of the plastic container 1. In addition, the slits 11 allow the magnet ring 7 can be bathed in the liquid introduced into the fuel container.
[0116] As shown in figures 5, 6 and 7 also the inner wall 10 of the annular compartment 6 has slits 12 in a similar way that serve the same purpose. Therefore, ring magnet 7 will be bathed on both sides, that is, on its inner side (inner circular face) and on its outer side (outer circular face). In addition, the two walls 8, 10 in the integration of the ring magnet 7 can slightly deviate in a radial direction to later return in a salty shape with a corresponding (elastic) prestressing so that the ring magnet 7 is in the desired position.
[0117] As it appears especially from figures 6 and 7, the annular compartment 6 has a relatively large axial expansion in relation to the annular magnet 7 especially also the outer wall 8 presents - in comparison with the annular magnet 7 - a relatively large axial length, with which it is achieved that the wall 8 in a region is joined with the filling tube 4, which is distanced relatively distant from the lower open end of the annular compartment 6. Thus, the radial deviation of the outer wall 8 is reinforced to receive the ring magnet 7.
[0118] The inner wall 10 offers an inner diameter, that is, an inner region, to receive the supply gun 5 and causes, on the one hand, the supply gun 5 to be guided and, on the other hand, causes that supply guns that exceed a defined diameter cannot be introduced.
[0119] As can be seen in figures 1,2, 8 and 9, the support of the filling tube 3 has two projections 13, that is, narrowing steps, that is, cams, of such conformation that when the filling tube is 4 inserted in the filler tube support 3, the two projections 13 are located below the annular compartment 6, when the two protrusions 13 reduce the free and available internal diameter of the filler tube support 3, at least in one region partial, that the internal diameter of the filling tube holder 3 is smaller than the outer diameter of the ring magnet 7.
[0120] In the execution example it is provided that the projections 13 are mutually opposite and occupy an angular area of 30 to 90 °. This shape can also serve to increase the stability of the filling tube support 3.
[0121] As also shown in the figures, the filler tube support 3 has an end stop 14 on its inner wall. The end stop 14 limits the possibility of inserting the filler tube 4, that is, it defines the depth of the introduction of the filler tube 4 in the filler tube holder 3. As is clear from figures 8 and 9, the filler tube 4 rests with a stop face 15 in such a way on the end stop 14 that the filler tube 4 is located positioned as intended inside the fill tube support 3.
[0122] In the execution example, the end stop 14 is shaped like a surrounding step.
[0123] In its outer circumference 18, the filling tube 4 has three ribs 16, that is, annular and surrounding protrusions, whose outer radial ends are contracted within the inner wall of the filling tube support 3. The ribs 16 extend , in this case, converging in a parallel plane. The ribs 16 are arranged at a regular converging distance. Between the ribs 16, rods 17 are provided for uniformly spaced from one another. The rods 17 extend essentially in an axial direction.
[0124] The lower side of the lower rib 16, surrounding in a circular direction, forms the abutment face 15 for the end stop 14 in the filler tube support 3.
[0125] As it appears especially from figures 3, 6, 7, 8 and 9, the ribs 16 present in their external ends, surrounding and in radial direction, that is, in the ends, which are contracted inside the inner wall of the tube support. filler 3, grooves 19 for anchoring the filler tube 4 in the support of the filler tube 3. In this case, seen in longitudinal section, the grooves 19 extend reciprocally in a cuneiform direction. The recesses 19 do not necessarily have to be formed around the ring shape, but they can also be arranged only in partial regions.
[0126] In the execution example, the inner diameter of the filler tube support 3, at least in the region where the filler tube 4 is integrated, narrows downwards towards the inner compartment of the container 1.
[0127] In the execution example it is also provided that a closure cap not shown in more detail for the purpose of closing the plastic container 1 can be screwed with the filling tube 4 or it can be attached there in another way. In this case, the filling tube 4 may have suitable closing means, for example, a thread.
[0128] Furthermore, in the execution example, in a manner not shown in more detail, between the outer circumference 18 and the outer wall of the filling tube 4 and the outer wall 8 of the annular compartment 6, ventilation holes are provided.
[0129] Between the outer circumference 18, that is, the outer wall of the filling tube 4 and the outer wall 8 of the annular compartment 6, reinforcement walls 20 may be provided that essentially extend in an axial direction and, among other aspects, conform, that is, they define the ventilation holes. Reinforcement walls 20 increase the stability of the filling tube 4.
[0130] Figure 11 shows a fuel tank 100 with first receiving compartment 101 for fuel and a second receiving compartment 102 for a second fuel, a working fluid or a working fluid component, in the example of execution a urea, or that is, an AdBlue. In this case, the second receiving compartment 102 is so shaped as described in the execution example according to figures 1 to 9. The second receiving compartment 102 therefore has an outer metallic film 2 with an internal plastic coating 1 , preferably produced by rotary sintering. The plastic inner lining represents a plastic container in the vessel 1. In the inlet opening 2a, the filler tube support 3 shaped according to the invention is integrally formed with the plastic container 1, which support in which a tube is contracted filling 4.
[0131] The second receiving compartment 102 is joined with the first receiving compartment, for example, being welded, so that a joint fuel tank 100 is formed for a utility vehicle.
[0132] This can be verified by the fact that the second receiving compartment 102 is initially produced as a separate container. The connection with the first receiving compartment 101 can, for example, be achieved by the fact that an open front face of the circumferential wall of the first receiving compartment 101 will be welded with a front wall 102a of the second receiving compartment 102. Alternatively, it can also be provided that both the front sides of the circumferential wall of the first receiving compartment 102 are closed by their own front walls. Therefore, the two receiving compartments 101 and 102 are shaped as separate containers and can - in a known manner - be welded together.
[0133] In addition, it is possible that the front wall - designated in figure 11 with reference number 102a - is formed as a partition wall that reciprocally separates the two receiving compartments 101, 102. In this case, the partition wall can be of metal , but it can also be produced by a synthetic material, for example, by a rotary sintering process.
[0134] Figure 10 shows an alternative mode of filling tube 4 in relation to figures 3 to 9. Basically, all the variant characteristics, which have already been mentioned in relation to filling tube 4 in the version according to figures 3 to 9, can also be realized in the support of the filling tube 4 according to figure 10, as long as this is not excluded by the subsequent modifications. The filler tube support 4 according to figure 10 differs from the filler tube support according to figures 3 to 9, in that instead of ribs 16, only grooves 19 are formed on the outer wall 18 of the filling tube support 4. The inventors recognized that the production costs can be reduced when instead of ribs 16 (with grooves 19) are formed only grooves 19. In addition, it was evidenced that the grooves of plug 19 are sufficient to allow a contraction of the filling tube 4 in the support of the filling tube 3.
[0135] In addition, the filling tube 4 shown in figure 10 differs in that in the outer circumference 18 a seal 24 (or possibly several seals) is provided so that the seal seals between the outer wall 18 of the filling tube 4 and an inner wall 3a of the filler tube support 3. For this purpose, in the embodiment shown in figure 10, it is provided that the seal 24 (radial) protrudes beyond the grooves 19. In addition, it may be provided that the seal 24 is inserted between two grooves 19, with which it is retained. The seal 24 can preferably be formed as a sealing ring.
[0136] The filling tube 4, shown in figure 10, has at its upper end an extended flanged section 21 that essentially projects in a radial direction. This flange-like widening 21 makes it possible for the filling tube to be fastened by screwing, for example, using screws 22. Preferably, four screws 22 are provided. Preferably, the fixing will take place in the filling tube support 3 which, for that, may present a counterface not presented in more detail. By screwing, the existing connection between the filling tube 4 and the filling tube support 3 can be reinforced. Torques can be welcomed by the screw, preferably by the screws 22, in a particularly satisfactory manner. The lower side of the flange 21 can preferably serve as the abutment face 15, so that in connection with the end stop 14 of the filling tube support 3, a defined positioning of the filling tube 4 is achieved. In this case, the lower side of the flange 21, that is, the abutment face 18 preferably rests on the upper side of the filler tube support 3, preferably on an upper face of the filler tube support 3, preferably on a counterface that also serves for the taper. In this case, the upper side, that is, the counterface of the filling tube support 4, will represent the end stop 14 (not shown in more detail).
[0137] The characteristics shown in figure 10 can also individually or in random combinations be combined with the embodiment of the filling tube 4 according to figures 3 and 9.
[0138] Figure 12 presents two alternative modalities. According to the first conformation, it is foreseen that the support of the filling tube 3 will be formed in one piece with the plastic container 1, that is, the plastic sintering layer 1. This can preferably be accomplished by the fact that a tool, intended for the rotary sintering, presenting a suitable shape so that the plastic material that forms on the inner side of the metallic outer film 2, the plastic sintering layer 1, simultaneously also according to the support of the filling tube 3. In a complementary or alternative way, you can it is also foreseen that the edge of the inlet opening 2a is curved outwards (see figure 12) so that on the inner side of the upwardly folded edge a plastic sintering layer 1 'is formed which, according to the first conformation , form the support of the filling tube 3. The tool, used for rotary sintering, may present such a segment as than that the filler tube support 3 receives an internal thread on its inner wall 3a. By the support of the filling tube 3, according to figure 12, the filling tube 4 can be joined with it by means of a screw. For this purpose, the filling tube 4 may have a corresponding external thread on its outer circumference 18. Such a connection can alternatively or in a complementary manner be used for a contraction process. This can, for example, be achieved by the fact that the internal thread of the filler tube support 3 extends only over a part of the height of the filler tube support 3.
[0139] In a complementary or alternative way, it can also be envisaged that the filling tube 4 has a flanged widening 21 as shown in figure 10, so that through a corresponding screw 22 with the filling tube support 3 it is screwed in according to figure 12.
[0140] In the example according to the execution according to figure 12, the filler tube support 3 has a seal 25 on its upper side. The seal 25 may, in this case, seal between the filler tube support 3 and the filling tube.
[0141] In the second alternative conformation according to figure 12, it can be predicted that in the case of segment 1 'in shape conformed to the plastic sintering layer 1, it is not only the support of the filling tube 3, but only of an enlargement of the entrance opening. In this case, a support of the filling tube 3 will be formed separately and by means of a screw with the partial part 1 'in the form of the plastic sintering layer 1, it will be joined by a screw. The screw tube 3 can then be connected to the filling tube 4 by means of a contraction.
[0142] Figure 13 shows an alternative conformation of the support of the filling tube 3 according to the embodiments. In this case, it is provided that the support of the filling tube 3 is shaped independently of the plastic container 1, that is, of the plastic sintering layer 1, as a separate component. In this case, the support for the filling tube 3 will be inserted into an inlet opening 2a of an outer metallic film 2. This is preferably done in such a way that the support of the filling tube 3 extends outwards and inwards through the inlet opening 2a. After inserting the filler tube support 3 into the inlet opening 2a, a plastic will be introduced into the inner compartment of the outer metallic film 2, so that it therein conforms to a sintered plastic layer 1 on the inner side of the outer metallic film 2. In this way, the sintered layer of plastic 1 also interconnects with the support of the filling tube 2 so that it will be disposed of loss-proof. The filler tube support will be fixed by a rotary sintering process.
[0143] The filling tube support will preferably also be heated by the sintering process, preferably also formed of plastic material, that its plastic material preferably melts slightly, resulting in a good connection with the layer sintered plastic.
[0144] To improve the connection of the filler tube support3, it can be provided that it has a notch, that is, a groove 30, or an indentation, so that the plastic sintered layer 1 can produce a union with closure due to the form.
[0145] A possible conformation of an indentation is shown in figure 13 by dashes and lines. It is advantageous that the support of the filling tube 3 can be positioned from outside on the outer metallic film 2, that is, a stop is formed, so that a defined backrest results.
[0146] The outer wall 3b of the filling tube holder 3 can - especially in that region where it is arranged inside the outer film 2 - may present a desired random shape, for example, grooves, a striation or similar conformation, so that it is a good connection is possible, that is, connection with the plastic sintered layer 1.
[0147] An advantage of the filling tube support 3 according to figure 13, is that the filling tube support 3, by the separate conformation, can receive a sufficiently large wall thickness, whereas the layer sintered plastic 1 has the smallest possible wall thickness. The wall thickness by the filler tube support 3 can be, for example, 4 to 10 mm, preferably 6 mm, while the wall thickness of the sintered plastic layer 1 is preferably 0.5 to 3 mm , especially preferred from 0.5 to 1 mm.
[0148] The filling tube support 3, shown in figure 13, adapts to join or fix all the filling gloves described above.
[0149] In an advantageous configuration for all execution variants, it can be provided that an edge 2100 of the inlet opening 2a is stamped (outwards or inwards), so that a clamping aid is created for a rotary sintering tool.
[0150] Figures 14 to 21 show another embodiment of the solution according to the present invention. The characteristics described below can be combined either individually, as well as in a random combination or in its entirety with the characteristics of the embodiments according to the figures described above. Likewise, the characteristics already described on the basis of figures 1 to 13 can be combined individually or in random combination or in their entirety with the embodiment according to figures 14 to 21.
[0151] Next, the divergent characteristics of figures 1 to 13 will be described based on figures 14 to 21.
[0152] Figure 14 shows a conformation of the support of the filling tube 3 with only one narrowing stage, that is, a projection 13, that is, a cam. For simplification, then, reference will be made only to a projection 13. The description, however, must apply at the same time for a narrowing stage, that is, for a narrowing or for a cam.
[0153] The projection 13 is shaped in such a way that, when the filling tube 4 is inserted in the support of the filling tube 4, the projection 13 is below the annular compartment 6, the projection 13 reducing the free diameter of the support of the filling tube 3, which is available, at least in a partial region, in such a way that the inner diameter of the support of the filling tube 3 is smaller than the outer diameter of the ring magnet 7.
[0154] The protrusion 13 has a face 130, which, from above, essentially has an arcuate circle shape.
[0155] In the support of the filling tube 3, shown in figure 14, in the form and procedure already described, a filling tube 4 will be contracted.
[0156] The filling tube 4 may, in this case, have a conformation as already described in relation to the embodiments according to figures 1 to 13.
[0157] A top view for possible conformation of the filling tube 4 is shown in figure 19 and a bottom view is shown in figure 20. The filling tube 4, shown in figures 19 and 20, has two ventilation channels 300 , whose ends projected in the internal compartment of the container 1, at least partially may be covered by one or possibly several protrusions of the support of the filling tube 3. In the embodiment shown in figures 14 to 21 it is provided that only one of the two channels of ventilation 300 is covered by the protrusion 13, that is, by its face 130. The ventilation channel 300 which extends essentially in an axial direction, therefore flows out, not in a straight direction, that is, axial in the internal compartment of the container. Between the end of the ventilation channel 300, facing the internal compartment of the container and the face 130 of the projection 12, an axial distance is provided so that air can flow from the internal compartment, exceeding the projection 13, to the ventilation channel. ventilation 300.
[0158] The outlet of liquids will, however, be clearly hampered because there is no straight line between the internal compartment of the container and the ventilation channel 300.
[0159] Of course, other projections 13 may also be provided, which eventually close several ventilation channels 300.
[0160] Figure 15 shows a presentation in which the filling tube 4, shown in figures 19 and 20, is contracted within the support of the filling tube 3. It is provided in the case that one of the two ventilation channels 300 of the filling tube filling 4, observed in axial direction, will not be covered by a projection 13, whereas the other ventilation channel 300 is covered by the projection 13 shown in figure 14, that is, by the face 130 thus formed. Of course, several or less ventilation channels 300 or projections 13 may also be provided. A sectional representation of the installation situation shown in figure 15 can be seen in figure 16. Here it can also be recognized that the air, passing next to the projection 13, can penetrate the ventilation channel 300 covered by the projection 13.
[0161] The inventor recognized that it is advantageous that the ventilation channel 300 - the end of which faces the inner compartment of the container 1 - is closed last by a level of rising liquid, that is, it is reached, being covered at least partially by overhang 13.
[0162] The inventor recognized in a not precisely detailed way that the danger will be greater than from the ventilation channel 300, which is finally closed by a level of rising liquid (in the supply) that produces a flow through urea sprays. Therefore, it will be advantageous that the ventilation channel 300, which is closed last, by the level of rising liquid in the internal compartment of the container, receives protection against nozzles that can be achieved in an especially simple way by the fact that the projection 13, in any anticipated manner, in such a way as to avoid a fall of the ring magnet 7, cover this ventilation channel 300 in such a way that a straight, ie axial, passage is not provided for the internal compartment of the tank.
[0163] Naturally, protection against splashes of this type could also be achieved independently of the protrusion, through a protruding lobe or by an arch. In the tests, however, it was especially approved to use the projection 14 for this purpose.
[0164] With ventilation channels 300 shown in figures 14 to 20, they present - considered in the cut, an arcuate circular shape. It is advantageous that the circular arcuate shape of the ventilation channel 300, which must be closed by the projection 13, is suitable at least approximately to the surface 130 of the projection 13 so that the support 130 of the projection 13 blocks approximately in the entire ventilation channel. 300 in the axial direction, considered in the axial direction (see figure 15).
[0165] As shown in figures 14, 16, 17, 18 and 21, it is advantageous that the projection 13 has a ventilation hole 400. The ventilation hole 400 is so arranged that it establishes a connection between the ventilation channel 300 and an air compartment 500 inside the container which is located above the inner end of the filling tube holder.
[0166] The ventilation hole 400 allows the volume to donate, closed in the inner compartment of the container, as soon as the level of liquid in the container is so high that one end of the filler tube support 3 towards the inner compartment, can extend to the outside.
[0167] The ventilation hole 400 can, for example, have a diameter of 1 mm up to 100 mm, preferably 5 mm +2 mm. This dimensioning proved to be especially suitable in order to allow an escape of air, however, to suppress as much as possible a flow through urea nozzles.
[0168] As is clear especially from figures 14 to 20, however, also from figures 1 to 10, the filling tube 4 forms a free space 600 in an annular shape that surrounds the annular compartment 6 for the magnet 7 on the outside. This ring free compartment 600 is opened in an upward direction towards the inner compartment of the container, so that air can penetrate ring free space 600. The free space in shape on the 600 link is in such a case in connection with the ventilation channels 300 that an air stream can be formed that allows the air in the container, in the supply of the container, to flow through the ventilation channels 300 to the outside. In order to make the most advantageous possible flow of air possible, it is especially appropriate that the ventilation channels 300 flow axially directly into the internal compartment of the container, without a blocking, ie an obstacle in axial direction. As already described above, however, it has been proven to be advantageous that the ventilation channel 300 closed last by the liquid level, is blocked, that is, covered by the projection 13 in an axial direction.
[0169] The possibility presented in figures 14 to 20 that the injector sleeve 4 is eventually screwed with the aid of screws 22 with the support of the filling tube 3, is optional.
[0170] In a way not presented in more detail, an annular cover can be provided that covers the support of the filling tube 3, including the flanged widening 21 of the filling tube 4 and keeps free, in the case, however, an opening to introduce the supply gun 5. Through a bayonet or other connection, a cap can be applied or screwed on the filler tube support 3, ie on the filler tube. For this purpose, the filling tube may optionally have a closing component 700.
[0171] All of the above-described variants of the filler tube holder 4 can be combined with all of the above-described variants of the filler tube holder 3.
