    The invention relates to a take-off assembly, in particular for blood samples, as described in claim 1.
    From EP 1 066 882 B1 there is a generic sample collection assembly for blood samples comprising a sample container having an open end, a bottomed end and a sidewall extending between the open end and the closed end and having an outer surface and an inner surface , The side wall is limited in the region of the open end with an end face, wherein, define the side wall and the bottom of a Sam¬melraum known. The sample container can be closed with a closure device and has a closure cap and a pierceable septum held on the closure cap. In its closed position, the closure device closes off the collecting space of the sample container in the region of its open end. The outer cap casing of the closure cap overlaps on the outside the open end of the sample container and supports itself on a support ring which is distanced from the open end. the inner capping jacket protrudes into the collecting space and abuts with a radially projecting annular shoulder on the inner surface of the side wall of the sample container. At the bottom facing the open front end of the inner cap skirt einurchstech bares septum is arranged.
    Other such blood sample collection assemblies have also become known from US 5,288,466 A and US 5,384,096 A.
    A disadvantage of all these sample collection arrangements that they were not easy to handle in all applications and a centrifugation of the absorbed body fluid was only possible with the help of additional Bau¬teilen. This is because such sample collection arrangements with respect to standardized blood sample collection tubes have lower dimensions for this purpose.
    It is an object of the present invention to provide a picker assembly particularly for the depletion of capillary blood, which offers more universal usage to the user.
    This object of the invention is solved by the features of claim 1.
    The advantage resulting from the features of claim 1 lies in the fact that by providing an additional annular skirt, which is connected thereto via a flange projecting radially beyond the side wall of the sample container, a cap-like component is provided directly on the sample container, by means of which the multiple, more universal Possible use is created. In a first application, after the body fluid, in particular the capillary blood, has been taken up, the removal assembly can be inserted into a standardized centrifuging device without the aid of additional components. By providing the flange in conjunction with the annular skirt, proper power transmission and associated support of the take-off assembly can thus be made directly to the respective centrifuge. In addition, however, this also creates the possibility of ensuring sufficient support and, if appropriate, mounting of the closure device on the sample container. When the closure device is mounted on the sample container, a cap-like shape can thus be created in cooperation with the annular apron, as is customary in blood cap sampling tubes standardized in medical technology.
    A further possible application results from using the tube-shaped free space formed between the inner annular skirt surface of the annular skirt and the outer surface of the side wall, in order to be able to insert the sample container into a standardized blood sampling tube or carrier tube, thus supporting the sample container to enable this tube. In this way, the more universal application possibility of the sample container is created, which can be supplied either alone or in conjunction with an additional carrier tube to a centrifugation. Furthermore, however, a simpler and more cost-effective production process is also possible since no additional parts have to be produced to create a functioning pick-up assembly.
    Also advantageous is a further embodiment according to claim 2, since this creates the possibility of being able to screw the sample container via the annular skirt arranged thereon with another arranged on a carrier tube threaded arrangement. As a result, an even more secure mutual connection can be created compared to a plug-in or terminal connection.
    A further advantage is an embodiment according to claim 3, characterized in that the Einfüll¬vorgang is made possible without additional components in the space provided for collecting or receiving space of the sample container. Thus, only the closure device is to be removed for the filling process and the filling process can take place immediately thereafter. By eliminating additional Bau¬teilen so the manufacturing and material costs of the acceptance module can be reduced.
    The embodiment according to claim 4, it is possible to perform a proper Ein¬ filling. Thus, not only during the Einfüllvorgan¬ges sufficient eye contact with the delivery point can be ensured, but it is also an unhindered in-flow of the abzunehmenden body fluid, especially the capillary blood, in the plenum possible.
    According to another embodiment variant according to claim 5, the possibility is created that a parking of the sample container is made possible directly on the tubular projection on a defined base or storage area. This occurs when the tubular projection ends on its side facing away from the ground in a plane oriented perpendicularly with respect to the longitudinal axis.
    Also advantageous is a development according to claim 6, characterized in that a doppel¬wandige cap is provided, in which the tubular or annular Frei¬raum formed between the outer Kap¬penmantel and the inner cap skirt serves to accommodate the usually lip-shaped receiving approach of the sample container , Further, the inner capping mantle provides a defined access opening from the closure cap to the collection space. Furthermore, the outer cap casing can be formed in such a way that it can be provided with corresponding auxiliary elements for easier operation and handling of the closure device.
    In the embodiment according to claim 7, it is advantageous that the access to the collecting space is interrupted when the closure device is set. In addition, a unit is created which can be removed together from the sample container and in turn placed in its closure.
    The development according to claim 8 ensures that the septum forms on its outer peripheral side with the inner surface of the side wall in the closure position a continuous, complete closure of the collecting space. This can be secured against the ingress of contaminants prevented until the removal of the closure device as well as the sterility are guaranteed to the first opening.
    As a result of the embodiment according to claim 9, sufficient support of the closure device on the sample container can be ensured in the transition region between the flange and the annular skirt. However, this can also be used in conjunction with the annular skirt in approximately the outer space shape of standardized caps, as they are used in blood sample tubes are formed.
    An embodiment according to claim 10 is also advantageous, since this allows even more exact mutual alignment of the closure device, in particular the closure cap, with respect to the sample container and the annular apron arranged thereon.
    According to one embodiment, as described in claim 11, so an unintentional release of the closure device from the sample container up to exceeding a predefined release force can be prevented. However, even when the closure device is in the closed position, an unintentional release of the closure device, such as, for example, slight shocks that occur when the filled removal assembly falls over, can be prevented.
    In this case, an embodiment according to claim 12 proves advantageous, because thereby a related assembly can be created, wherein in auf¬gesetzter closure device in cooperation with the ring apron an aperaturally continuous assembly is created. If, in addition, in the area of the open end face of the annular skirt which faces the floor, at its outer circumference, at least in sections, a collar protruding radially beyond the annular skirt is arranged, then a direct support of the outer cap skirt of the closure cap can be provided on a support ¬gefläche lying in the same position can be avoided. Thus, even in a reclined position of the take-off assembly, unintentional release of the obturator from the sample container can be prevented.
    According to an advantageous development according to claim 13, it is thus possible to supply the acceptance assembly also to an automated analysis process with standardized analyzers and to be able to carry out the investigations there. This is because, in such automated analysis methods, standardized dimensions with regard to length, cross-sectional shape and diameter or external dimensions are required. By inserting the sample container in the carrier tube, so a Abnahmebaugruppe can be provided, which corresponds to the standardized dimensions of Blutproben¬entnahmeröhrchen. Furthermore, however, the sample container, in particular its side wall, can also be formed with a dimension which is suitable for being inserted or received in the interior of the carrier tube. However, even with constant filling volume compared to previously used sample containers due to the enlargement of the outer dimension, a shorter distancing of the bottom from the open end can be achieved, as was the case with previously customary acceptance devices.
    Also advantageous is an embodiment according to claim 14, since thus a zusammen¬ associated and in use, a stable connection having Abgäh¬ assembly can be created. This makes it possible to connect the sample container without additional components with a standardized blood sample tube and thus to be able to carry out the previously described automated analyzes or investigations of the sample contents.
    Finally, however, an embodiment as described in claim 15, possible, since such a separation difficult or can be prevented at all. This is to ensure that a confusion of samples is possible, if, for. nuram carrier tube an information carrier is arranged or applied. Thus, the sample taken in the sample container can always be clearly assigned to a patient. So can be dispensed with a marking directly on Probenbehäl¬ter. Since the dimensions of the sample container are made smaller relative to the carrier tube, a larger amount of space is available for attaching the information carrier to the carrier tube. Standardized information carriers can thus be used.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    In each case, in a highly simplified, schematic representation:
    1 shows a sealed with a closure device sample container, in perspective view;
    2 shows the sample container with partially removed Verschlussvorrich¬tung of Figure 1, in axial section ..;
    Fig. 3 shows the sample container with closure device according to Figures 1 and 2, which is inserted into an additional carrier tube, in axial section.
    Fig. 4, the removal assembly according to Figures 1 to 3, in axial section and separated from each other position of the individual components.
    Fig. 5 shows the sample container used in a carrier tube according to FIGS. 1 to 4, with an additional anti-rotation device, cut in plan view.
    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description apply mutatis mutandis to the same parts with the same reference numerals. same component names can be transferred. Also, the location information chosen in the description, such as up, down, laterally, etc. related to the directly described and illustrated figure and these conditions are to be transferred in a change in position mutatis mutandis to the new situation.
    FIGS. 1 to 4 show a removal assembly 1 in different configurations, which is used in particular for the removal of body fluids, such as blood samples. This sampling assembly 1 shown here has compared to standard blood sampling tubes in the mostly standardized Stan¬dardabmessungen to a smaller outer dimension and a geri¬geres recording volume on. This take-off assembly 1 is preferably used for the removal of capillary blood, which is taken in only smaller quantities and is prepared for subsequent tests in the take-off assembly 1b.
    The sampling assembly 1 shown here comprises a sample container 2 and a closure device 3.
    The sample container 2 in turn has an open end 4 and a verschlosse¬nes end 5. The closed end 5 can be closed by a bottom 6. A side wall 7 extends between the open end 4 and the closed end 5. Furthermore, a longitudinal axis 8 extends between the open end 4 and the closed end 5, which may preferably also be referred to as the central longitudinal axis. The cross-sectional shape of the sample container 2 can be chosen very different, but usually a preferred cross-sectional shape is a circular cross-section. In order to enable demoulding of the sample container 2, which is preferably produced in an injection molding process, corresponding draft angles are to be provided, as is customary with such components. Preferably, a plastic material is further selected as the material for the sample container. In this case, the material can be predominantly transparent to crystal clear and be selected from the group of PP (polypropylene), PS (polystyrene), PET (polyethylene terephthalate), PE (Polyäthyl¬en), PA (polyamide), PC (polycarbonate).
    The side wall 7 of the sample container 2 further has an outer surface 9 and an inner surface 10 spaced apart in a wall thickness of the side wall 7 thereof. The side wall 7 is further delimited in the region of the open end 4 with an end surface 11. The side wall 7 with its inner surface 10 defines together with the bottom 6 a collecting space 12, which for receiving the abzunehmendenbzw. Body fluid to be filled, in particular blood, particularly preferably capillary blood, serves. The sample container 2 further comprises, at its open end 4 delimiting the end surface 11, a flange 13 projecting beyond the side wall 7 in the radial direction with respect to the longitudinal axis 8. The flange 13 faces away from the side wall 7 and from the longitudinal axis 8 Side outer flange 14 on.
    At this averted from the side wall 7 flange 14 further is a skirt 15 is arranged or formed, wherein the annular skirt 15 aus¬gehend extending from the flange 14 in the axial direction of the bottom or the closed end 5 of the sample container 2 out. The annular skirt 15 has an inner annular skirt surface 16 facing the side wall 7 or its outer surface 9. Furthermore, between the outer surface 9 and the Seiten¬wand 7 and the side wall 7 facing inner ring skirt surface 16 of the annular skirt 15 a formed approximately tubular free space 17.Dieser this circumferentially continuous clearance 17 extending axially from the end facing away from the flange 13 the annular skirt 15 up to the flange 13. Thus, in the axial direction of the free space 17 in the region of the open end 4 through the flange 13 is completed or limited.
    The sample container 2, the flange 13 and the annular skirt 15 preferably form a one-piece component, which is usually produced in an injection molding process in an injection molding tool in a known manner.
    The function of the flange 13 with the annular skirt 15 arranged distanced from the outer surface 9 of the side wall 7 will be explained in more detail in one of the following figures.
    In a possible development, it is provided that a first thread arrangement 18 is arranged or formed on the inner annular skirt surface 16 of the annular skirt 15. It should be mentioned that under threaded arrangement einin- or multi-start thread as well as several threads or Ge¬windesegmente can be understood. Thus, it would be possible, for example, to form the first thread arrangement 18 in such a way as has been described in EP 1 711 412 B1 of the same applicant for the cap described there for closing the receptacle.
    It would thus also be possible to use the method described in EP 1 711 412 B1 for assembling the detaching assembly 1 described here. The detailed explanations follow in the description relating to FIGS. 3 and 4.
    In order to facilitate a filling of the sample, in particular of the blood, into the collecting space 12 of the sample container 2, a receiving opening 19 which is in particular lip-shaped can be provided. The receiving lug 19 is preferably arranged on the end face 11 and integrally connected to the side wall 7. It also extends beyond the end face 11 of the open end 4 in the axial direction in the direction away from the bottom 6. It is possible that the receiving lug 19 extends only over a portion of the circumference of the side wall 7. A collecting approach area 20 facing the collecting space 12 is approximately rectilinear in the axial direction, in particular planar, into the inner area 10 formed by the side wall 7. This allows a smooth transition and a simplified filling without additional disturbing retention edge.
    Furthermore, the sample container 2 can have at its closed end 5 a tubular projection 21, which projects beyond the end 5 closed with the bottom 6 in the axial direction in the direction away from the open end 4. For the most part, the projection 21 terminates at its end facing away from the open end 4 in a plane oriented perpendicular to the longitudinal axis 8. This plane forms, for example, a footprint for the take-off assembly 1 to lift it on a non-illustrated storage surface, such as a laboratory bench or the like, in a vertical orientation Due to the planar formation of the projection 21, a certain dispensing of the bottom 6 from the likewise open end of the projection is achieved, whereby the overall length of the sample container 2 is determined depending on the projection of the projection 21 in the axial direction beyond the bottom 6 can be. But this also makes it possible, for example, with the same component length of the sample container 2 to arrange the bottom 6 at a predetermined distance from the end face 11 in the interior of the side wall 7 so as to adapt the recording volume exactly to the particular application desired or to vote can.
    The closure device 3 in turn comprises a closure cap 22 with an outer cap casing 23, an inner cap casing 24 arranged at a distance in the radial direction with respect to the longitudinal axis 8 and an end wall 25 connecting the two cap casings 23, 24 in the radial direction The two cap shells 23, 24 are aligned concentrically relative to one another with respect to the longitudinal axis 8. The connection of the two cap coats 23, 24 in the radial direction through the end wall 25 takes place with the closure cap 22 attached to the open end 4 of the sample container 2 on the side of the closure cap 22 facing away from the open end 4. The inner cap jacket 24 forms a passage opening, in order to avoid this even with attached closure device3 to allow access into the plenum 12.
    The closure device 3 comprises in this embodiment, in addition to the cap 22 also held on the cap 22, piercable Bares septum 26. The septum 26 is used to seal the collecting space 12 with respect to the external environment with attached Ver¬ closing device 3. Thus, the pierceable septum 26 may also be formed from a self-resealing material. As the material, one of the group of bromobutyl rubber, TPE, rubber, rubber can be selected. As a preferred material TPE can be used, since this can also be processed in an injection molding process. The septum 26 is designed such that in the closed position of the closure device 3 it forms a liquid-tight and / or gas-tight closure of the collecting space 12 in the region of the open end 4.
    In this embodiment, the septum 26 is disposed or formed at a front end 27 of the inner cap skirt 24 that is spaced apart from the end wall 25 and is open. Furthermore, the septum 26 has a radially encircling sealing surface 28. In the closed position, the septum 26 is inserted into the open end 4 of the sample container 2, so that the sealing surface 28 rests against the inner surface 10 of the side wall 7 in the closed position. This concern takes place in particular sealing manner. Thus, the collection chamber 12 or receiving space can also be closed in the region of the open end 4 with attached closure device 3. Furthermore, the septum 26 extends over the entire open end 4 of the sample container 2 in the region of its inner surface 10 over its entire area. The septum 26 is designed as a disc-shaped component in the present embodiment and is connected to or arranged on the inner cap jacket 24. With different material choice between the cap 22 and the septum 26, the connection can be made by gluing, welding or other thermal or chemical connection processes. Regardless of this, it would also be possible, if different materials were selected, to produce the closure device 3 in a co-injection molding process. However, a further possibility would also be to form the entire closure device 3 comprising the closure cap 22 and the septum 26 from one and the same material.
    The outer cap casing 23 also has an open front end 29 on its side opposite the end wall 25. When the closure device 3 is in the closure position, the open front end 29 of the outer cap jacket 23 bears against the flange 13 or the annular skirt 15. This takes place mostly in the corner or transition area between the components described above.
    2 and 3, a centering arrangement 30 can be provided between the open front end 29 of the outer cap casing 23 and the flange 13 or the annular skirt 15. The centering arrangement 30 comprises cooperating, first and second centering elements 31,32, which interact in the closed position accordingly. Thus, in this exemplary embodiment, the first centering element 31 is designed as a centering groove which is open towards the outside and which is arranged or formed in the flange 13 or the annular skirt 15 in its transition region. Vor¬zugt the first centering element 31 is continuously formed over the entire circumference of the flange 13 and the annular skirt 15.
    The second centering element 32 forms the open front end 29 of the outer Kap¬penmantels 23. Furthermore, it can be seen here that the outer Kappenmantel23 the inner cap casing 24 projects beyond in the axial direction. This extent may correspond to the depth or the length of the first centering element 31 extending in the axial direction.
    In addition, however, it would also be possible for a holding device 33 to be formed or provided between the open front end 29 of the outer cap jacket 23 and the flange 13 or the annular skirt 15. For better clarity, the representation of the holding device 33 is dispensed with, wherein the holding device 33 can comprise cooperating first and second holding elements. Thus, in addition to the centering of the closure cap 22 or the entire closure device 3, a certain holding or locking between the closure device 3 and the Probenbe¬hälter 2, in particular its open end 4, in the transition region between the flange 13 and the annular skirt 15th respectively.
    Preferably, the flange 13 or the annular skirt 15 has an outer cross-sectional shape or outer dimension, which corresponds approximately to an outer cross-sectional shape of an outer outer dimension of the outer cap skirt 23. This can be avoided in the transition region between the annular skirt 15 and the flange 14 of the flange 13 and the äuße¬ren cap jacket 23 protruding edges. In addition, but also an optically related unit is created. On the annular skirt 15, in the region of its open front end, on the outer surface thereof, a radially projecting bead preferably formed continuously over the circumference can be provided. This bead serves, in the assembled state, when the detachment assembly 1 is disposed, to prevent the closure device 3, in particular its closure cap 22, from directly resting on a bearing surface (not shown). If the bead is formed only partially and / or with a radially overhanging outer surface of the annular skirt that is different in circumference, a rolling movement of the take-off assembly 1 can be prevented.
    The dimension of the inner cap skirt 24, seen in the radial direction, is preferably selected to approximately correspond to the internal cross-sectional dimension of the inner surface 10 of the side wall 7. Preferably, however, the outer dimension is chosen to be slightly smaller. The septum 26 preferably projects beyond the inner cap jacket 24 in the radial direction. In order to achieve a corresponding pre-centering between the septum 26 and the inner cap casing 24, it would still be possible to provide here also a suitably designed centering arrangement, for example in the form of a peripheral annular groove. Moreover, it would also be possible to use only individual holding elements provided on the inner cap casing 24, so as to additionally achieve a mechanical support of the septum 26 on the closure cap 22, in particular its inner cap casing 24.
    As can now be better seen in FIGS. 3 and 4, the take-off assembly 1 may further comprise an additional carrier tube 34. The dimensions of the carrier tube 34 may correspond to those standard dimensions as used in the usual blood sampling tubes. Thus, for example, the diameter may be 13 mm or 16 mm, which may have a length of, for example, 70 mm or 100 mm.
    The carrier tube 34 comprises an open first end region 35 and a second end region 37 closed preferably with a carrier tube bottom 36. The sample container 2 described above can with its side wall 7 and optionally the projection 21 arranged thereon into the interior space of the carrier tube 34 are used, wherein the open educated, first end portion 35 of the carrier tube 34 protrudes into the formed between the outer surface 9 of the side wall 7 and the annular skirt 15, tubular free space 17. In this case, the flange 13 serve as a stop or limit for the opposite movement of the two components. When fully inserted, the end face of the carrier tube 34 can come to rest on the flange 13 and be supported.
    Preferably, the carrier tube 34 has in the region of its open end region 35 and on its outer surface 38 a second thread arrangement 39 or is provided with it. This makes it possible for the user of the specimen container 2 to be able to use it in a standardized centrifuge to form the decoupling assembly 1, for example for the centrifugation of the blood filled into the collecting chamber 12 or the receiving space.
    From Fig. 4, the individual parts for forming the entire take-off assembly 1 are shown in a separate position in the manner of an exploded view generally used in the art. For the formation of the closure device 3, the closure cap 22 is to be provided with the septum 26 or to be formed therewith. In order to be able to provide a sterile interior or collection space 12 for delivery, the closure device 3 is to be placed on the open end 4 so that, on the one hand, the sealing surface 28 of the septum 26 is brought into contact with the inner surface 10 of the side wall 7. The outer cap casing 23 of the closure cap 22 can be supported on the outer transition region between the flange 13, in particular its flange end 14, and the annular apron 15. An additional centering by the Zentrieranordnung30 can also be done. In order to carry out the collection and filling of the blood into the collection chamber 12, the closure device 3 is to be removed and the filling process may then be carried out, if appropriate, with the aid of the receiving attachment 19. If sufficient quantities are filled into the collecting space 12, the open end 4 is again closed by the closing device 3.
    Thus, it is possible to subject the sample container 2 with the sample contained therein directly to a centrifugation or other evaluation processes and analyzes. In this case, the support or installation of the sample container 2 on the bottom 6 facing the front end or the end face of the annular skirt 15 take place.
    If this support or installation of the ring skirt 15 on the centrifuge not shown here is not possible, the sample container 2 can be inserted in its closed state with the closure device 3 into the carrier tube 34, as has already been described above. Mutual fixing or holding of the sample container 2 can take place via the cooperating first and second thread arrangements 18 and 39, respectively.
    As already mentioned briefly above, the mounting of the sample container 2 on the carrier tube 34 can take place in such a way as described in EP 1 711 412 B1. Since the annular skirt 15 together with the flange 13 form a cap-like component on the sample container 2, in principle the joining process of the sample container 2 with the carrier tube 34 can be effected in an equivalent manner, but adapted to the existing components.
    Carrier tube 34 corresponds to the receptacle as described in EP-B1. By contrast, no sealing device is provided directly inside the annular skirt 15 in the present invention. During the joining process, the open-ended end which is openly formed by the cap-like ring skirt 15 with its open front end facing the carrier tube 34 becomes the open end region 35 of the carrier tube 34 attacks.
    By providing the two threaded assemblies 18, 39 with their zusammenamendenwirken threads between the annular skirt 15 and the Träger¬röhrchen 34, the assembly can be performed by a relative rotation or Schwenkbe¬wegung about the common longitudinal axis 8. Furthermore, a plurality of sample containers 2 with the support tubes 34 to be joined for forming the removal assemblies 1 can also be simultaneously moved into a common assembly device, not shown here. For the joining operations, one of the components to be assembled is supported rotatably about its longitudinal axis 8 on a thrust bearing of the mounting device, wherein a pressure force (F) directed approximately in the direction of the longitudinal axis 8 is exerted by the mounting device on at least one of the components to be assembled becomes. In this case, the compressive force (F) for generating the Relativbe¬wegung in the relative rotational or pivotal movement about the common longitudinal axis 8 is implemented by the co-operating thread of the threaded assemblies 18, 39. During the relative pivotal movement, the threads of the threaded assembly 18, 39 may engage each other over the entire length of the insertion path until the fully threaded position is reached. This unscrewing movement can be terminated by abutting end face of the open first end region 35 of the carrier tube 34 on the flange 14.
    Regardless of this, however, a pure plug-in connection without the provision of the two thread arrangements 18 or 39 would also be possible.
    However, after the centrifuging operation has taken place and the separation of the blood has taken place lighter and heavier constituents, for example, the lighter constituent arranged adjacent to the open end 4 can be removed from the collecting space 12. This can be done either by the closure device 3 being removed from the open end 4 of the sample container 2 or by the puncturable septum 26 having a non-illustrated
    Removal device is removed from the plenum 12. This can be done spielsweise by a suction or the like.
    FIG. 5 shows a further and, if appropriate, separate embodiment of the take-off assembly 1 with the sample container 2 inserted into the carrier tube 34, in particular so that it is connected via the threaded arrangements 18, 39 in plan view, again with the same reference numerals for the same parts or component designations as in the vorhergan¬genen Fig. 1 to 4 are used. To avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS.
    For some reasons of subsequent sample analysis or further processing and further treatment of the sample contents of the removal assembly 1, it may be necessary to secure the sample container 2 with its annular skirt 15 after insertion and screwing or connection to the carrier tube 34 against accidental unscrewing or removal , This can then be the case if, for example, the sample container 2, in particular des¬sen side wall 7, is not provided with an information carrier or, especially the carrier tube 34. Would the removability or separation of the sample container 2 from the carrier tube 34th be possible, the case could arise that only the carrier tube 34 is provided with the corresponding information or the information carrier and the sample contained in the sample container 2 can no longer be uniquely assigned to a patient by the non-marking.
    Therefore, it may be advantageous if between the cap-like Ringschür¬ze 15 of the sample container 2 and the carrier tube 34 an additional Ver¬drehsicherungsvorrichtung 40 is provided or arranged. This twisting device 40 can be formed by a wide variety of cooperating snap elements or securing elements, which allow the sample container 2 to be joined to the carrier tube 34. When the two thread arrangements 18, 39 are provided, this takes place by a screwing-on movement about the longitudinal axis 8, the direction of rotation being indicated by a first arrow 41 for the connection process. With a further arrow 42, however, the oppositely directed rotational movement is shown, which is to erschwe¬ren or prevent at all.
    In the present exemplary embodiment, the or the anti-rotation devices 40 are formed on the annular apron surface 16 and in the direction of the longitudinal axis 8 projecting thereon. In order to enable a screwing operation unhindered in the direction of the first arrow 41, a flat, preferably gradient-free slope is provided here.
    In order to prevent the sample container 2 from being screwed off from the carrier tube 34 in the opposite rotational movement according to arrow 42, the anti-rotation device 40 has a locking surface 43 or stop surface. This is usually arranged in a direction perpendicular to the Abschraub¬bewegung - according to arrow 42 - aligned plane, so as to engage and queuing, for example. to achieve on one of the first threads of the threaded assemblies 18. Thus, the unscrewing difficult or even prevented. However, other arrangements or configurations of the anti-rotation device 40 forming elements could be selected. When changing the Aufschraubrichtung, as is well known in right- or left-hand threads, the arrangement and orientation of the Ver¬drehsicherungsvorrichtung 40 and their elements to be adapted to the respective selected directions of rotation.
