Definitions
- the invention relates to a coaxial two-component cartridge according to the preamble of claim 1.
- Such coaxial two-component cartridges are advantageously made so that the outer tube and the inner tube are manufactured separately.
- the two tubes must then be plugged together to obtain a coaxial cartridge. It must be ensured by a suitable latching that the inner tube is firmly anchored to the outer tube. A release of the inner tube during transport and filling of the cartridge must be prevented. Even a not well secured, in particular no longer centrally arranged inner tube can cause problems in automatic filling by the filling no longer finds the inner tube.
- the build-up internal pressure in the cartridge also acts on the bottom of the inner tube, which, if insufficiently anchored, can cause the inner tube to become detached and the cartridge can no longer be pressed out.
- the paragraph can be removed from the rear as an undercut, so that the cartridge can be made closed with molded cap. There the undercut must be forcibly demolished, the paragraph can not be performed sharp-edged and the width of the paragraph is limited to a few tenths of a millimeter. This leads to a greatly reduced, potentially insufficient holding power.
- a two-piece coaxial cartridge in which the inner tube is made of aluminum. Sawtooth-shaped ribs are attached to the inner tube. The aluminum saw teeth dig into the soft plastic outer tube during pressing in, forming a solid anchorage.
- the disadvantage of this solution is that the use of aluminum pipes is expensive, and a cartridge consisting of metal and plastic in disposal is ecologically problematic.
- a two-part coaxial cartridge which is made of inexpensive plastic, suitable for a closed, integrally connected to the cartridge and by tearing, cutting or canceling openable outlet, and at which securely holds the anchorage of the inner tube and ensures its centric positioning.
- the holding force for fixing the inner tube relative to the outer tube by a fir tree-like rib structure on the outside of the neck of the inner tube on a plurality of groove flanks on the inside of the neck of the outer tube and thus evenly over a significant part of the length of both Distributed necks. This ensures a tight fit of the connection and a stable coaxial position of both tubes relative to each other even with only a small groove depth and a rounded shape of the grooves.
- the inner profile of the outer tube which has a plurality of successive grooves, advantageously in the injection molding process with final demolding in a single direction, namely opposite to the subsequent installation direction of the inner tube, are produced.
- a small groove depth is a forced removal, with a formation of the grooves as a thread and a spindles possible.
- connection of the two tubes can be performed by axial pressing, wherein the ribs are bent back against the installation direction and remain permanently in such a deformed state, to exert an axial holding force on the inner tube.
- connection can also be made by screwing, wherein the holding force results from the screw.
- the two tubes are arranged coaxially to each other and thereby define a gap 4 in the form of a hollow cylinder, in which one of the two for simultaneous extrusion from the cartridge 1 certain components of an adhesive or the like.
- the other component contains the interior 5 of the inner tube 3.
- the outer tube 2 and the inner tube 3 are manufactured separately and connected to each other before the cartridge 1 is filled with the two components.
- Fig. 1A shows the state after the insertion of the inner tube 3 in the outer tube 2, but before bringing about a mechanical connection of the two tubes 2 and 3.
- Fig. 1B shows the state in which the two tubes are firmly connected and ready to fill the two components. Since the components of the two tubes 2 and 3 in the Figures 1A and 1B are identical, not all reference numbers are entered in both figures.
- the mechanical connection of the two tubes 2 and 3 takes place in the region of the outlet channels for the two components forming necks 6 and 7.
- the neck 6 of the outer tube 2 in its lower region on the inside a plurality of similar grooves 8, the equidistant in the axial direction.
- the depth of the grooves 8 is dimensioned so that in the production by injection molding still a forced removal on the inside of the neck 6 is possible.
- the grooves 8 extend in the axial direction, starting from the lower end of the neck 6 over slightly more than the lower half. They lie in mutually parallel planes whose normal direction is in each case the axial direction of the cartridge 1.
- the neck 7 of the inner tube 3 on its outer side a plurality of similar, integrally molded ribs 9, which also follow each other equidistantly in the axial direction.
- the axial spacing of the ribs 9 corresponds to that of the grooves 8.
- the outer diameter of the neck 7 of the inner tube 3 including the ribs 9 is greater than the clear diameter of the grooves 8.
- the axial length of the region of the neck 7 of the inner tube 3, over which the ribs 9 extend corresponds approximately to the axial length of the region of the neck 6 of the outer tube 23, over which the grooves 8 extend, ie the number of ribs 9 is at least approximately equal to the number of grooves 8, but it does not correspond to a exact match arrives.
- the number of grooves 8 and ribs 9 is between 10 and 15, and is in the in the Figures 1A and 1B Example 13 shown.
- the grooves 8 and ribs 9 are intended to engage with each other when the inner tube 3 is pushed into the outer tube 2 until it stops.
- This stop is determined by other ribs 10, which differ from the extending lower end of the neck 7 of the inner tube 3, starting along the outside in an approximately radial direction.
- These ribs 10 are adapted in shape to the contour of the inner surface of the outer tube 2 in the region of the transition 11 of an at least approximately radially extending end wall 12 thereof to the neck 6. Over the circumference of the inner tube 3 at least three, in the example shown four ribs 10 are evenly distributed.
- the height of the ribs 10 defines the height of the passage channel, through which the component located in the hollow cylindrical space 4 between the outer tube 2 and the inner tube 3 flows radially in the direction of the necks 6 and 7 when the cartridge 1 is pressed out.
- the inner space 5 of the inner tube 3 is sealed relative to the hollow cylindrical space 4 between the two tubes 2 and 3, so that the two components located in the spaces 4 and 5 in the cartridge 1 can not come into contact and react ,
- the in the Figures 1A and 1B ribs 16 visible on the outside of the outer neck 6 constitute a thread provided for screwing on a closure cap for reclosing a used cartridge 1 or a static mixer for mixing the two components and is not related to the present invention.
- the axial thickness of the ribs 9 on the outside of the inner tube 3 is designed in relation to its radial length so that the ribs upon exertion of a predetermined axial force on the inner tube 3 in the in Fig. 1A bend position shown so far down that the neck 7 of the inner tube 3 can slide into the neck 6 of the outer tube 2 until the previously explained, in Fig. 1B shown stop position is achieved.
- the transition 11 of the outer tube 2 to its neck 6 is also bevelled on the inside, so that in a non-centric position of the two tubes. 2 and 3 to each other in axial force loading of the inner tube 3, the oblique outer surface of that nose 17, which first comes into contact with the outer tube 2, slide on said bevelled inside of the transition 11 along and the inner tube 3 can move in the direction of the centric position.
- Fig. 1B Upper right also shows an enlarged section of the region of the two necks 6 and 7, in which the outer tube 2 and the inner tube 3 are connected to each other by the action of the ribs 9 in the final assembled state of the cartridge 1. It is clearly evident that the ribs 9 are no longer in the radial direction outwards due to their length, which slightly exceeds the clear width of the grooves 8, after pressing the neck 7 of the inner tube 3 in the neck 6 of the outer tube 2, but in contrast are slightly inclined, namely backwards with respect to installation direction, ie the direction of movement of the inner tube 3 at said pressing.
- each rib 9 in the final assembly state of the cartridge 1 is comparable to that of the branches of a Christmas tree, each rib 9 is engaged in a groove 8 and is supported at its end in this, ie in particular at its lower edge.
- the degree of inclination depends on how much the outer diameter of the neck 7 including the ribs 9 exceeds the clear width of the grooves 8.
- the ribs 9 are able due to their tendency to transmit a large axial force component to the lower groove flanks and thereby reliably prevent disengagement, i. Solution of the connection.
- FIG. 2A A side view of the inner tube 3 of the cartridge 1 in the unmounted initial state is in Fig. 2A shown enlarged.
- the two types of ribs 9 and 10 and the lugs 17 are even more clearly visible than in the cross-sectional view of the two mounting phases in the Figures 1A and 1B , In particular shows Fig. 2A
- the ribs 9 do not extend annularly around the entire neck of the inner tube 3 around, but in the circumferential direction form individual segments, between each of which rib-free segments 18 are located.
- the latter form in the final assembly state of the cartridge 1 vertical channels between the two necks 6 and 7, through which the component located in the intermediate space 4 between the outer tube 2 and the inner tube 3 component can flow when squeezing the cartridge 1. It does not depend on a precisely vertical course of these channels, but only that there are any passages for said component in the vertical direction, which could for example also run helically.
- the outer diameter of the neck 7 of the inner tube 3 including the ribs 9 and the inner diameter of the neck 6 of the outer tube 2 decrease slightly towards the respective outlet end.
- this slight conicity which is known with regard to demoulding in injection-molded parts, ensures that the force required to press in the inner neck 7 into the outer neck 6 increases slightly less with increasing press-in depth than is possible with constant external forces. or inner diameters would be the case.
- the outer diameter of the inner neck 7 at the level of the uppermost of the ribs 9 including the same is still greater than the inner diameter of the outer neck 6 at its lower beginning, so that even the uppermost of the ribs 9 must be bent down during pressing to to snap into the bottom of the grooves 8 can.
- the inner tube 3 has two mutually perpendicular axes of symmetry, so that its neck 7 has four circumferential segments with ribs 9, four ribs 10 and four circumferential segments 18 without ribs.
- the neck 7 is not hollow cylindrical shaped, but recessed concavely in the region of its rib-free peripheral segments 18 in order to increase the cross-section of there formed in the final assembly state of the cartridge 1 together with the neck 6 of the outer tube vertical outlet channels for the extrusion of the cartridge 1.
- approximately 35% of the cross-sectional area lying in the final assembly state between the inside of the outer neck 6 and the outer side of the inner neck 7 is covered by the ribs.
- the covered area of the cross section may also be substantially larger or smaller.
- the substantially radially extending end wall 19 of the inner tube 3 extends in the region of the upwardly projecting from their ribs 10 flange over the mantle surface of the inner tube 3 and therefore also has substantially the shape of a cross. In this way, a correspondingly greater length of the ribs 10 is made possible, by which a correspondingly more stable support of the inner tube 3 on the end wall 12 of the outer tube 2 is achieved.
- FIGS. 3A and 3B A second embodiment of the present invention is disclosed in FIGS FIGS. 3A and 3B shown, where Fig. 3A analogous to Fig. 1B the final assembly state of the cartridge 101 and Fig. 3B analogous to Fig. 2A a side view of the inner tube 103 shows.
- the reference numerals of corresponding components of the two embodiments always differ by the number 100.
- the shape of the outer tube 102 is largely the same as that of the first embodiment described above.
- the inner tube 103 compared to the first embodiment has a larger diameter, but this is not important.
- the essential difference with respect to the first embodiment is rather in the form of ribs 109 on the outside of the neck 107 of the inner tube 103 and in the matched shape of the grooves 108 on the inside of the neck 106 of the outer tube 102.
- the ribs do not extend in the unassembled state of the inner tube 103 each in a plane whose normal direction is the axial direction of the cartridge 1, but the ribs 109 form a screw thread on the outside of the neck 107. Accordingly, the grooves 108 in the neck 106 form a matching internal thread. Although in the second embodiment after injection molding, a forced removal of the grooves 108 is intended, its depth is of the same order of magnitude as in the first embodiment. Alternatively, the grooves 108 can also be removed from the mold by unwinding, which allows a greater depth of the grooves 108 as well as an angular profile of the same.
- the ribs 109 are thicker in the axial direction of the cartridge 101 than in the first embodiment, and in contrast to the latter, are not designed to be brought into a deformed state during assembly of the cartridge 101, they are in the final Permanently maintain mounting condition. Rather, the ribs 109 are either not appreciably deformed at all, which is the case when the connection between the outer tube 102 and the inner tube 103 is made by screwing the external thread formed by the ribs 109 into the internal thread formed by the grooves 108, or The neck 107 of the inner tube 103 is pressed into the neck 106 of the outer tube 102 as in the first embodiment, resulting in temporary elastic deformations and snap over the threads several times before they interlock in the final position of the two tubes 102 and 103.
- the latter mounting method requires a relatively small depth of at least one of the two threads, wherein preferably the internal thread formed by the grooves 109 is designed so flat that it can be demolded by forced removal.
- the construction of the second embodiment largely corresponds to that of the first, so that a further explanation of the other design features, such as acting as axial stops ribs 110 and the vertical outlet channels creating, rib-free peripheral segments 118 of the neck 107, can be dispensed with.

Description
Die Erfindung betrifft eine Koaxial-Zweikomponentenkartusche nach dem Oberbegriff des Anspruchs 1.The invention relates to a coaxial two-component cartridge according to the preamble of claim 1.
Derartige Koaxial-Zweikomponentenkartuschen werden vorteilhaft so hergestellt, daß das Außenrohr und das Innenrohr separat hergestellt werden. Die beiden Rohre müssen dann nachträglich zusammengesteckt werden um eine Koaxialkartusche zu erhalten. Es muß durch eine geeignete Verrastung sichergestellt werden, daß das Innenrohr fest mit dem Außenrohr verankert wird. Ein Lösen des Innenrohres beim Transport und beim Abfüllen der Kartusche muß verhindert werden. Schon ein nicht gut befestigtes, insbesondere nicht mehr zentrisch angeordnetes Innenrohr kann beim automatischen Abfüllen Probleme bereiten, indem die Abfüllvorrichtung das Innenrohr nicht mehr findet. Ferner wirkt beim Auspressen der Kartusche der sich aufbauende Innendruck in der Kartusche auch auf den Boden des Innenrohres, was bei einer ungenügenden Verankerung dazu führen kann, daß sich das Innenrohr löst und so die Kartusche nicht mehr auspreßbar ist.Such coaxial two-component cartridges are advantageously made so that the outer tube and the inner tube are manufactured separately. The two tubes must then be plugged together to obtain a coaxial cartridge. It must be ensured by a suitable latching that the inner tube is firmly anchored to the outer tube. A release of the inner tube during transport and filling of the cartridge must be prevented. Even a not well secured, in particular no longer centrally arranged inner tube can cause problems in automatic filling by the filling no longer finds the inner tube. Furthermore, when the cartridge is pressed out, the build-up internal pressure in the cartridge also acts on the bottom of the inner tube, which, if insufficiently anchored, can cause the inner tube to become detached and the cartridge can no longer be pressed out.
Gemäß dem Gebrauchsmuster
Grundsätzlich kann der Absatz auch als Hinterschneidung von hinten entformt werden, so daß die Kartusche geschlossen mit angespritztem Verschlußdeckel hergestellt werden kann. Da die Hinterschneidung dabei zwangsentformt werden muß, kann der Absatz nicht scharfkantig ausgeführt werden und die Breite des Absatzes ist auf wenige Zehntel-Millimeter begrenzt. Dies führt zu einer stark reduzierten, potentiell ungenügenden Haltekraft.Basically, the paragraph can be removed from the rear as an undercut, so that the cartridge can be made closed with molded cap. There the undercut must be forcibly demolished, the paragraph can not be performed sharp-edged and the width of the paragraph is limited to a few tenths of a millimeter. This leads to a greatly reduced, potentially insufficient holding power.
Gemäß der
Ändere Beispiele für des Befestigen eines Innenrohrs und einem Aussenrohr sind aus
In Anbetracht dieses Standes der Technik ist es die Aufgabe der Erfindung, eine zweiteilige Koaxialkartusche zu schaffen, die aus kostengünstigem Kunststoff herstellbar ist, sich für einen geschlossenen, mit der Kartusche einteilig verbundenen und durch Abreißen, Aufschneiden oder Abbrechen zu öffnenden Auslaß eignet, und bei der die Verankerung des Innenrohres sicher hält und eine zentrische Positionierung desselben gewährleistet wird.In view of this prior art, it is the object of the invention to provide a two-part coaxial cartridge, which is made of inexpensive plastic, suitable for a closed, integrally connected to the cartridge and by tearing, cutting or canceling openable outlet, and at which securely holds the anchorage of the inner tube and ensures its centric positioning.
Die Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.The object is achieved by the features specified in claim 1. Advantageous developments of the invention can be found in the dependent claims.
Durch die Erfindung wird erreicht, daß sich die Haltekraft zur Fixierung des Innenrohres gegenüber dem Außenrohr durch eine tannenbaumartige Rippenstruktur an der Außenseite des Halses des Innenrohres auf eine Vielzahl von Rillenflanken auf der Innenseite des Halses des Außenrohres und damit gleichmäßig über einen signifikanten Teil der Länge beider Hälse verteilt. Dies gewährleistet einen festen Sitz der Verbindung und eine stabile koaxiale Position beider Rohre relativ zueinander auch bei einer nur geringen Rillentiefe und einer abgerundeten Form der Rillen.By the invention it is achieved that the holding force for fixing the inner tube relative to the outer tube by a fir tree-like rib structure on the outside of the neck of the inner tube on a plurality of groove flanks on the inside of the neck of the outer tube and thus evenly over a significant part of the length of both Distributed necks. This ensures a tight fit of the connection and a stable coaxial position of both tubes relative to each other even with only a small groove depth and a rounded shape of the grooves.
Dabei kann das Innenprofil des Außenrohres, welches eine Vielzahl von aufeinanderfolgenden Rillen aufweist, vorteilhaft im Spritzgußverfahren mit abschließender Entformung in einer einzigen Richtung, nämlich entgegengesetzt zur späteren Einbaurichtung des Innenrohres, hergestellt werden. Bei einer geringen Rillentiefe ist eine Zwangsentformung, bei einer Ausbildung der Rillen als Gewinde auch ein Ausspindeln möglich.In this case, the inner profile of the outer tube, which has a plurality of successive grooves, advantageously in the injection molding process with final demolding in a single direction, namely opposite to the subsequent installation direction of the inner tube, are produced. With a small groove depth is a forced removal, with a formation of the grooves as a thread and a spindles possible.
Die Verbindung der beiden Rohre kann durch axiales Einpressen ausgeführt werden, wobei die Rippen entgegen der Einbaurichtung zurück gebogen werden und dauerhaft im solchermaßen verformten Zustand verbleiben, um eine axiale Haltekraft auf das Innenrohr auszuüben. Bei einer Ausführung der Rillen und Rippen als zueinander passende Gewinde kann die Verbindung auch durch Eindrehen hergestellt werden, wobei sich die Haltekraft aus der Schraubverbindung ergibt.The connection of the two tubes can be performed by axial pressing, wherein the ribs are bent back against the installation direction and remain permanently in such a deformed state, to exert an axial holding force on the inner tube. In an embodiment of the grooves and ribs as mating thread, the connection can also be made by screwing, wherein the holding force results from the screw.

Die mechanische Verbindung der beiden Rohre 2 und 3 erfolgt im Bereich der die Auslaßkanäle für die beiden Komponenten bildenden Hälse 6 bzw. 7. Hierzu weist der Hals 6 des Außenrohres 2 in seinem unteren Bereich an der Innenseite eine Vielzahl von gleichartigen Rillen 8 auf, die äquidistant in Axialrichtung aufeinanderfolgen. Die Tiefe der Rillen 8 ist so bemessen, daß bei der Herstellung im Spritzguß noch eine Zwangsentformung an der Innenseite des Halses 6 möglich ist. Die Rillen 8 erstrecken sich in Axialrichtung ausgehend vom unteren Ende des Halses 6 über etwas mehr als dessen untere Hälfte. Sie liegen in zueinander parallelen Ebenen, deren Normalenrichtung jeweils die Axialrichtung der Kartusche 1 ist.The mechanical connection of the two
Als Gegenstück zu den Rillen 8 an der Innenseite des Halses 6 des Außenrohres 2 weist der Hals 7 des Innenrohres 3 an seiner Außenseite eine Vielzahl von gleichartigen, einstückig angeformten Rippen 9 auf, die ebenfalls äquidistant in Axialrichtung aufeinanderfolgen. Dabei entspricht das axiale Rastermaß der Rippen 9 demjenigen der Rillen 8. Der Außendurchmesser des Halses 7 des Innenrohres 3 einschließlich der Rippen 9 ist größer als der lichte Durchmesser der Rillen 8. Die axiale Länge des Bereiches des Halses 7 des Innenrohres 3, über den sich die Rippen 9 erstrecken, entspricht etwa der axialen Länge des Bereiches des Halses 6 des Außenrohres 23, über den sich die Rillen 8 erstrecken, d.h. die Anzahl der Rippen 9 stimmt zumindest annähernd mit der Anzahl der Rillen 8 überein, wobei es aber nicht auf eine exakte Übereinstimmung ankommt. Die Anzahl der Rillen 8 und Rippen 9 liegt zwischen 10 und 15, und beträgt bei dem in den

Die axiale Dicke der Rippen 9 an der Außenseite des Innenrohres 3 ist im Verhältnis zu ihrer radialen Länge so ausgelegt, daß die Rippen sich bei Ausübung einer vorbestimmten Axialkraft auf das Innenrohr 3 in der in
Zur axialen Zentrierung des Halses 7 des Innenrohres 3 gegenüber dem Hals 6 des Außenrohres 2 sind oberhalb der Rippen 10 mehrere, d.h. mindestens drei, im gezeigten Beispiel vier Nasen 17 einstückig an den Hals 7 angeformt, die eine schräge Außenoberfläche aufweisen. Passend hierzu ist der Übergang 11 des Außenrohres 2 zu seinem Hals 6 an der Innenseite ebenfalls abgeschrägt, so daß in einer nichtzentrischen Position der beiden Rohre 2 und 3 zueinander bei axialer Kraftbeaufschlagung des Innenrohres 3 die schräge Außenoberfläche derjenigen Nase 17, welche zuerst mit dem Außenrohr 2 in Kontakt gelangt, auf besagter abgeschrägter Innenseite des Übergangs 11 entlang gleiten und sich das Innenrohr 3 in Richtung auf die zentrische Position bewegen kann.For axial centering of the

Bei einer Beaufschlagung des Innenrohres 3 mit einer axialen Kraft entgegen der seiner Einbaurichtung vermögen die Rippen 9 aufgrund ihrer Neigung eine große axiale Kraftkomponente auf die unteren Rillenflanken zu übertragen und verhindern dadurch zuverlässig eine Ausrastung, d.h. Lösung der Verbindung.When the

Der Außendurchmesser des Halses 7 des Innenrohres 3 einschließlich der Rippen 9 sowie der Innendurchmesser des Halses 6 des Außenrohres 2 verringern sich in Richtung auf das jeweilige Auslaßende zu geringfügig. Diese leichte Konizität, die bei Spritzgußteilen im Hinblick auf die Entformung bekannt ist, sorgt in vorliegenden Fall dafür, daß die zum Einpressen des inneren Halses 7 in den äußeren Hals 6 benötigte Kraft mit zunehmender Einpreßtiefe etwas weniger stark zunimmt, als es bei gleichbleibenden Außen- bzw. Innendurchmessern der Fall wäre. Der Außendurchmesser des inneren Halses 7 auf der Höhe der obersten der Rippen 9 einschließlich derselben ist jedoch noch immer größer als der Innendurchmesser des äußeren Halses 6 an seinem unteren Anfang, so daß bereits die oberste der Rippen 9 beim Einpressen nach unten gebogen werden muß, um in die unterste der Rillen 8 einrasten zu können.The outer diameter of the

Die im wesentlichen radial verlaufende Stirnwand 19 des Innenrohres 3 erstreckt sich im Bereich der von ihr aus nach oben ragenden Rippen 10 flanschartig über die Manteloberfläche des Innenrohres 3 hinaus und weist daher ebenfalls im wesentlichen die Form eines Kreuzes auf. Hierdurch wird eine entsprechend größere Länge der Rippen 10 ermöglicht, durch die eine entsprechend stabilere Abstützung des Innenrohres 3 auf der Stirnwand 12 des Außenrohres 2 erreicht wird.The substantially radially extending
Eine zweite Ausführungsform der vorliegenden Erfindung ist in den
Bei der zweiten Ausführungsform stimmt die Form des Außenrohres 102 weitestgehend mit derjenigen der zuvor beschriebenen ersten Ausführungsform überein. Im Verhältnis zum Außenrohr 102 hat das Innenrohr 103 im Vergleich zur ersten Ausführungsform einen größeren Durchmesser, was aber nicht von Bedeutung ist. Der wesentliche Unterschied gegenüber der ersten Ausführungsform liegt vielmehr in der Form Rippen 109 an der Außenseite des Halses 107 des Innenrohres 103 sowie in der auf diese abgestimmten Form der Rillen 108 an der Innenseite des Halses 106 des Außenrohres 102.In the second embodiment, the shape of the
Wie aus
Die Rippen 109 sind in der Axialrichtung der Kartusche 101 dicker als bei der ersten Ausführungsform und im Gegensatz zu dieser nicht dazu bestimmt, bei der Montage der Kartusche 101 in einen Verformungszustand gebracht zu werden, den sie im endgültigen Montagezustand dauerhaft beibehalten. Vielmehr werden die Rippen 109 entweder überhaupt nicht nennenswert verformt, was dann der Fall ist, wenn die Verbindung zwischen dem Außenrohr 102 und dem Innenrohr 103 durch Eindrehen des von den Rippen 109 gebildeten Außengewindes in das von den Rillen 108 gebildete Innengewinde hergestellt wird, oder der Hals 107 des Innenrohres 103 wird wie bei der ersten Ausführungsform in den Hals 106 des Außenrohres 102 eingepreßt, wobei es zu vorübergehenden elastischen Verformungen kommt und die Gewindegänge mehrmals überschnappen, bevor sie in der Endposition der beiden Rohre 102 und 103 ineinander einrasten. Die letztgenannte Montagemethode setzt selbstverständlich eine relativ geringe Tiefe zumindest eines der beiden Gewinde voraus, wobei vorzugsweise das durch die Rillen 109 gebildete Innengewinde so flach ausgelegt wird, daß es durch Zwangsentformung entformbar ist.The
Ansonsten entspricht die Konstruktion der zweiten Ausführungsform weitestgehend derjenigen der ersten, so daß auf eine erneute Erläuterung der weiteren Konstruktionsmerkmale, wie der als axiale Anschläge fungierenden Rippen 110 und der vertikale Auslaßkanäle schaffenden, rippenfreien Umfangssegmente 118 des Halses 107, verzichtet werden kann.Otherwise, the construction of the second embodiment largely corresponds to that of the first, so that a further explanation of the other design features, such as acting as
Aus der vorausgehenden Beschreibung der beiden Ausführungsbeispiele ergeben sich für den Fachmann eine Reihe von Abwandlungen der Erfindung. So kann beispielsweise die Anzahl der Umfangssegmente mit Rippen, deren Länge in Umfangsrichtung im Verhältnis zu den rippenfreien Segmenten, sowie deren Anordnung in Umfangsposition über der Höhe variiert werden. Ebenfalls variierbar sind z. B. auch die Profile der Rippen und der Rillen im Längsschnitt sowie die Länge der mit Rippen bzw. Rillen versehenen Halsabschnitte. Solche und vergleichbare Modifikationen, die im Ermessen des Fachmannes liegen, sollen vom Schutz des Patents umfaßt sein.From the foregoing description of the two embodiments will be apparent to those skilled in a number of modifications of the invention. Thus, for example, the number of circumferential segments with ribs whose length in the circumferential direction in relation to the rib-free segments, as well as their arrangement in circumferential position above the height can be varied. Also variable z. As well as the profiles of the ribs and the grooves in longitudinal section and the length of the provided with ribs or grooves neck portions. Such and similar modifications, which are at the discretion of the person skilled in the art, are intended to be covered by the patent.
