DESCRIPTION OF A PRESENTLY PREFERRED EMBODIMENT

[0093] With reference to FIGS. 1 through 5, the exemplary embodiment will be described first according to the technical teaching of the independent claim 1, wherein the packaging sleeve 1 consists of two packaging sleeves 2, 12 inserted coaxially one into the other.

[0094] The packaging sleeve 1 thus consists of a cylindrical outer sleeve 2 and a sealing closure 10, which closes the opening side 4 of the outer sleeve 2, as well as an inner sleeve 12 accommodated in the interior of the outer sleeve 2 and accommodated in the interior 19 in a position in which it is rotated by 180 and also has a sealing closure 30.

[0095] The sealing closure 10 on the outer sleeve has an outer thread 8, which cooperates with the respective inner thread 9 on the opening side 4 of the outer sleeve 2. The sealing closure 10 can be screwed into the opening side 4 of the outer sleeve 2 in this way.

[0096] A number of sealing ribs 7 arranged parallel to one another and arranged at an axial distance from the outer thread 8 are arranged on the outside circumference of the sealing closure 10 in the area of the elastomerically deformable annular wall 16 at the front axially. These sealing ribs are inclined toward the rear in the direction of insertion and are thus in sealing contact with the inside circumference 21 of the outer sleeve 2. The receiving opening 15 formed by the annular wall 16, open at one end, is designed as a conical inclination 17 having a cone angle 18.

[0097] The conical inclination 17 of the receiving opening 15 may be designed to be smooth or may also have a thread-type profile.

[0098] The opening side 4 of the outer sleeve 2 is offset by a shoulder 20 of a reduced diameter from the remaining interior 19 of the outer sleeve 2, and the bottom sleeve 22 has a conical constriction and is closed at the bottom. The bottom sleeve 22 is thus sealed by the bottom side 3.

[0099] The front end 5 of the opening side 4 is open and has a peripheral edge, which is stopped at the respective peripheral stop edge 6 on the circumference of the sealing closure 10 when screwed in.

[0100] FIG. 2 shows all the parts from the exploded diagram in FIG. 1, so that their mutual relationship is discernible.

[0101] The sealing closure 30 has a receiving opening 35, which widens conically toward the outsidein the same way as the sealing closure 10. This opening is formed through an annular wall 36, on the outside circumference of which sealing ribs 37 are integrally molded. Here again, the inside circumference of the receiving opening 35 may be smoothed or may be profiled with threads.

[0102] The sealing closure 30 is screwed onto the opening side 40 of the inner sleeve 12 in the direction of the arrow 28. It is assumed that the object 25 is already accommodated with its head 26 in the interior 39 of the inner sleeve 12.

[0103] In many application cases, it may happen that the diameter of the head 26 of the object 25 is selected so that the head 26 is clamped in the conically widened receiving opening 35, and this receiving opening 35 is spread radially outward so that the sealing ribs 37 press against the inside circumference 54 of the of the inner sleeve 12 with an increased contact pressure.

[0104] FIG. 1 thus shows that the length of the inner sleeve 12 is selected so that its sealing closure 30 is supported on the bottom side 3 of the outer sleeve 2 in the interior 19, and the length 43 (see FIG. 3) of the inner sleeve 12 is selected so that the conically tapering bottom sleeve 22 of the inner sleeve 12 penetrates into the outer sleeve 2 in the direction of the arrow 14, into the receiving opening 15 in the sealing closure 10 and executes an expansion movement directed in the radial direction of the arrow 13, forcing the peripheral annular wall 16 radially outward in the direction of the arrow 13 in the sealing closure 10 and pressing the sealing ribs 7 against the inside circumference 21 of the outer sleeve 2 under an increased contact pressure.

[0105] The multiple successive sealing ribs in FIG. 1 are labeled in general with reference numeral 7. To show that each sealing rib is peripheral and defines a separate sealing chamber 57, 58 in combination with the neighboring sealing rib, the individual sealing ribs are labeled with separate reference numerals. The outermost sealing rib axially is labeled with reference numeral 56, the next sealing rib in the axial direction is labeled with reference numeral 57 and, finally, the following sealing rib is labeled with reference numeral 59.

[0106] The sealing ribs 55, 56, 59 that are closed per se on the circumference and the individual sealing chambers 57, 58, which are compressed when an expansion pressure 11 acts in the radial direction of the arrow 13 and the seal on the inside circumference 21 of the outer sleeve 2 is thereby greatly improved.

[0107] FIG. 2 shows that it is preferable if the receiving opening 15 has a cone angle 18 in the sealing closure 10 and for the outside circumference of the bottom sleeve 24 of the inner sleeve 12 to have a cone angle 18 that is the same or at least similar.

[0108] The cone angle 18 of the sealing stopper 10, 30 and the bottom sleeve 24 of the inner sleeve 12 may however, also differ from one another.

[0109] The bottom sleeve 24 of the inner sleeve 12 is thus clamped in the central receiving opening 15 of the sealing closure 10. When the sealing closure 10 is unscrewed out of the outer sleeve 2, the inner sleeve 12 remains clamped in the receiving opening 15.

[0110] The expansion pressure thereby generated is labeled with reference numeral 11 in FIG. 1.

[0111] FIG. 1 also shows that the inner sleeve 12 is accommodated centrally in a 180 offset position in the interior of the outer sleeve 2 and is supported with its sealing closure 30 on the bottom side 3 of the outer sleeve 2. The sealing closure 30 is constructed in the same way as the sealing closure 10, so that all the preceding descriptions for the sealing closure 10 also apply to the structure of the sealing closure 30.

[0112] Before reaching the sterile area of the operating room, the inner sleeve 12 is removed from the outer sleeve 2 by opening the sealing closure 10 as shown in FIG. 2. In doing so, the inner sleeve 12 with its bottom sleeve 24 remains clamped in the conical receiving opening 15 of the sealing closure 10 that has been removed. Handling thus involves contact only with the sealing closure 10 but no contact with the inner sleeve 12.

[0113] In the sterile area of the operating room, a suitable person will open the sealing closure 30 by unscrewing it from the inner sleeve 12 according to FIGS. 1 and 2, wherein the object 25 to be held is removed from the interior 39 of the inner sleeve. It is either loosely accommodated in the inner sleeve 12 or it is held with its head 26 in a clamping action in the conical inclination 27 in the receiving opening 35.

[0114] According to FIG. 3, the head 46 of an object 45 may also be clamped securely against an annular collar 38 having a reduced diameter of the inner sleeve 12 with the help of a pressure piece 42 arranged in the sealing closure 30.

[0115] In all three cases, the sterile object 25, 45 can then be removed from the inner sleeve 12 and introduced into the sterile operating field without further contact.

[0116] The inner sleeve 12 is constructed in the same way as the outer sleeve 2 and has a shoulder 23 arranged on the bottom side, developing into a bottom sleeve 24, which has a conically tapering diameter.

[0117] The bottom sleeve 24 is the expansion member for spreading apart the receiving opening 15 in the sealing closure 10. The inside thread 41 for screwing with the outside thread 31 on the outside circumference of the sealing closure 30 is arranged in the area of the opening side 40.

[0118] Furthermore, the sealing ribs 37 arranged on the outside circumference are arranged in the area of the annular wall 36 and are spread apart in the radial direction by the head or by another holding element of the object 25.

[0119] Here again, the length of the object 25 is such that it abuts at its front end against the bottom wall of the bottom sleeve 24, so that when the sealing closure 30 is screwed into the inner sleeve 12, the head 26 penetrates into the conically tapering receiving opening 35 and spreads it apart radially from the outside.

[0120] In another embodiment, it is of course possible for the length of the object 25 to be selected to be shorter and to provide axial or radial stops in the interior of the inner sleeve, on which the object 25 is stopped in a secured position, so that when the sealing closure 30 is secured into the opening side 40 of the outer sleeve 12, the head 26 penetrates into the conically tapering receiving opening 35 and spreads it apart.

[0121] The invention is also not limited to holding an object like a screw, as illustrated in the drawings. Any other instrument or any other object 25 may also be held in the inner sleeve.

[0122] In another embodiment, it may also be provided that the length of the object 25 is shorter than the inside length of the inner sleeve 12, so that there need not be any axial or radial stops for the object 25.

[0123] In this case, it may be provided that the object 25 with its expansion member (for example, the head 26) is already inserted in advance into the conical receiving opening 35, which is thus already spread open.

[0124] In an exploded diagram, FIG. 4 shows and arrangement of a packaging sleeve consisting of an outer sleeve 2 and an inner sleeve 12, in which the object 45 to be packaged together with its head 46 is accommodated on an annular collar 38 of a reduced diameter in the interior 39 of the inner sleeve 12. To protect the object 45 that is to be held in order to prevent movement in the interior 39 of the inner sleeve 12, the object is clamped securely with the help of a pressure piece 42.

[0125] On penetration of the object 45 into the inner sleeve 12, the inner sleeve must still be present loosely or may be inserted only as a preliminary matter and with a slight depth of penetration with its pressure piece 42 into the receiving opening 35 of the sealing closure 30. However, as soon as the sealing closure 30 with its outside thread is screwed onto the respective inside thread of the inner sleeve 12, the pressure piece 42 penetrates further into the interior of the receiving opening 35 of the sealing closure 30 in the direction of the arrow 14 until the stop edge 44 that has been widened radially in diameter is in contact with the respective front end of the receiving opening 35. The pressure piece, which preferably has a conical design, thus results in radial expansion of the sealing ribs 37 on penetration into the receiving hole 35 of the sealing closure 30 and in an increased sealing of the sealing closure 30 in the interior of the inner sleeve 12.

[0126] As indicated by the arrow 29 in FIG. 4, the inner sleeve 12 that has been completely assembled is then inserted into the outer sleeve 2 with the object 45 now clamped securely under axial pressure, and the total length of the inner sleeve 12, including the completely assembled sealing closure 30, is chosen so that, when the sealing closure 10 is screwed onto the outer sleeve 2, the conically tapering bottom sleeve 24 of the inner sleeve penetrates into the conically widened receiving opening 15 and widens the receiving opening 15 radially, so that the sealing ribs 7 are in contact with the inside of the outer sleeve 2 under an increased contact pressure.

[0127] The invention is not limited to the exemplary embodiment shown in FIG. 4 because it may be provided in another embodiment (not shown in the drawings) that the pressure piece 42 is also provided for expansion of the receiving opening 15 in the sealing closure exactly as described above with reference to the inner sleeve 12.

[0128] Then, in this case, the conical bottom sleeve 24 of the inner sleeve 12 will not engage in the receiving opening 15 but instead a pressure piece 42 is then partially inserted into the receiving opening 15 and this pressure piece 42 penetrates completely into the receiving opening 15 of the sealing closure 10 when the sealing closure 10 is screwed on and it also widens this.

[0129] It is thus clarified that not just the bottom sleeve 24 of the inner sleeve can serve as the expansion member for the outer sealing closure 10, but also the sealing closure 10 can be expanded radially by a pressure piece 42 that is not shown in greater detail, as explained in the example according to FIG. 4 on the basis of the sealing closure 30 in combination with the inner sleeve 12.

[0130] FIG. 5 shows an exemplary embodiment that has been modified in comparison with FIG. 4, in which it is shown that the head 46 of an object to be held is also suitable directly as an expansion member for expansion of the receiving opening 35 in the sealing closure 30 near the inner sleeve.

[0131] The same explanations otherwise apply to the same parts as those shown in FIG. 4.

[0132] FIG. 5 also shows the penetration of the bottom sleeve 24 according to FIG. 4 in to the receiving opening 15 of the outer sealing closure 10. FIG. 4 shows the exploded diagram, while FIG. 5 shows the diagram of the device after being completely assembled, wherein the sealing ribs 7 are now pressed against the inside circumference of the outer sleeve 2 under the expansion effect of the conical bottom sleeve 24 with an increased contact pressure.

[0133] FIGS. 6 and 7 show different embodiments of a sealing closure, wherein each sealing closure can be used either for the outer sealing closure 10 and/or for the inner sealing closure 30.

[0134] FIG. 6 shows the penetration of a pressure piece 42 with a conical part into the conically widened receiving opening 15, 35 of the sealing closure 10, which is designed in two parts in the exemplary embodiment shown here.

[0135] The annular wall 16, 36, which has the sealing ribs 7, 37, is made of a softer plastic material than comparatively the screw part 48, which is situated above it and has the outer thread 8 and/or 31.

[0136] The sealing closure 10, 30 shown in FIG. 6 thus consists of two plastic materials bonded together in one piece at the factory, wherein the plastic of the radially spreadable annular wall 16, 36 consists of a softer plastic material than comparatively the plastic of the screw part 48 arranged above it.

[0137] In modification of the embodiment according to FIG. 6, FIG. 7 shows that the entire sealing closure 10, 30 may consist of a harder plastic, which also extends into the annular wall 16 in the hard embodiment.

[0138] However, a softer sealing sleeve 49 is integrally molded on or inverted over the outside circumference of the annular wall 16, the sealing ribs 7, 37 that are deformable under a radial expansion pressure being arranged on the outside circumference of the wall.

[0139] FIG. 8 shows three different embodiments of a pressure piece 42 whose function was already explained with reference to FIG. 4.

[0140] The shaping of the pressure piece, in particular its bottom side, depends mainly on the type of head 46 of an object 45 to be clamped with the aid of the pressure piece 42.

[0141] In the upper diagram according to FIG. 8, the pressure piece 42a is furnished with a curved surface 51, which is directed outward with a convex shape and exerts a uniform contact pressure on the head 46 of the object 45 to be heldaccording to FIG. 4.

[0142] In the second diagram in FIG. 8 the pressure piece 42b is furnished with a tip 50, which penetrates into a respective hole (not shown) in the central area of the head 46 of an object 45 and thus ensures additional centering for an object 45 to be held in the area of the inner sleeve 12.

[0143] The same centering is obtained due to the concave surface 52 of the pressure piece 42c in FIG. 8 because a head surface adapted thereto can also be centered on this concave surface.

[0144] FIGS. 9 and 10 show different designs of the sealing ribs 7, 37 of a sealing closure 10, 30. It is assumed in FIG. 9 that the sealing closure consists of the upper screw part 48 and the lower sealing part 53 on the outside circumference of which the different profile shapes of sealing ribs 7, 37 are integrally molded.

[0145] It is shown in the upper diagram in FIG. 10 that the expansion pressure 11 of an expansion member acts on the inside circumference 54 of the sealing part 53 in the direction of the arrow 13 and thus leads to a radially outward directed deformation of the sealing ribs 7, 37, because these sealing ribs undergo uniform radially inward deformation under the influence of a counterpressure 32 by contact with the inside circumference of the outer sleeve 2 and/or the inner sleeve 12. The approximately uniformly symmetrical and triangularly profiled sealing ribs 7, 37 are therefore also deformed uniformly under the influence of the counterpressure 32 as shown at the upper left of FIG. 10 on the basis of the sealing rib 7.

[0146] In the central diagram on the left side of FIG. 10, the sealing ribs 7a, 37a are already designed with a curvature and are therefore flattened under the influence of a counterpressure acting inwardly directed and are in contact specifically with large area sealing surfaces on the inside circumference of the outer sleeve 2 or the inner sleeve 12.

[0147] The lower diagram on the left side in FIG. 10 shows that the front side of the respective sealing ribs 7b may also be flattened and not zigzag-shaped as shown at the top of FIG. 10 so the result is a different deformation geometry under the influence of the counterpressure 32.

[0148] In the diagram at the upper right in FIG. 10, the asymmetrical sealing ribs 7c are also deformed in the direction of the arrow 33 because a counterpressure acts on the respective asymmetrical tip of the sealing rib 7c in the direction of the arrow 32.

[0149] In contrast with the diagram at the upper right of FIG. 10, the central diagram shows that the free outer ends of the sealing ribs 7d, 37d may also be designed as tips that become larger toward the outside radially and then flatten under the influence of a counterpressure and thus form linear contact faces on the inside circumference of the outer sleeve 2 and/or of the inner sleeve 12.

[0150] The diagram at the bottom of FIG. 10 on the right side shows that it is sufficient to also design the sealing ribs 7e, 37e just with a curvature.

[0151] Because of the softness of the elastomeric material used, these curved sealing ribs 7e, 37e are also compressed and unfold straight large area contact faces, establishing a superior sealing effect on the inside circumference of the outer sleeve 2 and/or the inner sleeve 12.

[0152] FIG. 11 shows as one exemplary embodiment a modification of the shaping of the outside circumference of the bottom sleeve 24 of the inner sleeve 12.

[0153] As indicated in the general description part, in a modified embodiment it may be provided that the outside circumference of the conically tapering bottom sleeve

[0154] 24 is not designed to be smooth but instead has friction-increasing profile elements.

[0155] These profile elements 34a, 34b should permit a controlled removal or controlled extraction of the inner sleeve 12 from the receiving opening 15 in the outer sealing closure 10. When the bottom sleeve is pulled out of the receiving opening 15, a controlled extraction should be possible without any great application of force, and the traction force should be exerted in the most controlled possible manner.

[0156] Thus FIG. 11 shows a screw profile 34a on the outside circumference of the conically tapering bottom sleeve 24, so that the inner sleeve 12 is not extracted out of the sealing materials 10 of the outer sleeve with an axial pulling force but instead with a screw-like motion.

[0157] Thus a controlled removal of the inner sleeve 12 from the sealing closure 10 of the outer sleeve 2 is possible.

[0158] This is also illustrated in FIG. 13 where it is indicated by the use of reference numerals that the same features may also be provided for forming the sealing closure 30, wherein thenin modification of the description aboveeither the pressure piece 42 of the friction-increasing profiles 34a, 34b or in the case of the design according to FIG. 5, when the head 46 of an object to be held acts directly as an expansion member in the sealing stopper 30, the head 46 is then furnished with the profile shapes 34a, 34b on the outside circumference.

[0159] However, for the sake of a simpler description, only the profile shape on the outside circumference of the bottom sleeve 24 of the inner sleeve 12 will now be discussed with reference to FIGS. 11 to 13, although the invention is not limited to this.

[0160] In modification of FIG. 11, FIG. 12 shows that, instead of a conically tapering bottom sleeve 24, a cylindrical bottom sleeve, in which the rib profiles 34b that are shown are eliminated first, may also be used. The bottom sleeve is then a smooth cylinder and can also be inserted into the conically tapering receiving opening 15 of the sealing closure 10 with an expansion force.

[0161] However, an improved expansion force also occurs when ribs of a larger diameter are arranged on the outside circumference of the cylindrical bottom sleeve 24.

[0162] FIG. 13 shows that it is not essential to the solution to bring the cone angle 18 of the conically tapering bottom sleeve 24 into correspondence with the cone angle 18 of the conically narrowing receiving opening 15.

[0163] The exemplary embodiment according to FIG. 14 has the same sealing closure 30 as that already described in the preceding description on the basis of FIGS. 1 to 13.

[0164] The same reference numerals have been used for the same parts. All the explanations and advantages of the first exemplary embodiment are also applicable here.

[0165] The main difference between the exemplary embodiment according to FIG. 1 and that according to FIG. 14 is the sealing arrangement on the left side, which now has a special sealing ring 60 according to the invention. However, it is pointed out that the sealing ring 60 and its special sealing functions can also be used in combination with the sealing closure 30 shown on the right side.

[0166] The sealing ring 60 may thus be arranged on the left side in FIG. 14 in the sealing closure 10 and/or also on the right side in FIG. 14 in the case of the sealing closure 30, wherein all information about the type or design of the sealing ring 60 also applies to the sealing closure 30 on the right side.

[0167] In the exemplary embodiment according to FIG. 14, therefore a higher level sealing arrangement is shown on the left side between the outer sleeve 2 and the stopper-type sealing closure 10 merely for reasons of simplifying the drawing.

[0168] This sealing arrangement is characterized in that the sealing closure 10 extends with its sleeve-type end into the interior of the outer sleeve 2, where it forms an outside thread 8, which cooperates with a respective inside thread 9 on the inside of the outer sleeve 2.

[0169] It is important that the thread engagement between the threads 8, 9 is shifted axially inward to the interior of the outer sleeve 2 and axially outward the sealing arrangement is now formed on the left side of the thread arrangement 8, 9.

[0170] The thread engagement between the respective threads 8, 9 is selected so that a defined locking position is achieved in a certain rotational position, so that this ensures that the stopper-type sealing closure 10 is always screwed with its outside thread 8 into the respective inside thread 9 of the outer sleeve 2 in the same positional and rotational orientation.

[0171] The exemplary embodiment according to FIG. 14 is characterized in that, due to the fact that the two respective threads 8, 9 are screwed together, the result is a first axial sealing location 62, which is arranged on the free outer end of a sealing sleeve 61, which is connected to the wall of the outer sleeve 2 in one piece at the factory.

[0172] The sealing location 62 is thus formed by the front end of the sealing sleeve 61 on the outside wall end and a sealing ring 60, wherein the sealing ring 60 forms an axial stop at the sealing location 62 and thus forms the sealing location 62.

[0173] Due to the two threads 8, 9 being screwed together, thus a first axial seal is established at the sealing location 62.

[0174] The sealing location 62 is thus formed by an axial stop 63 in the area of the sealing ring 60.

[0175] In the exemplary embodiment according to FIG. 15, which is an enlarged diagram of the view in FIG. 14, it can be seen that the sealing ring 60 is a part with an approximately L-shaped profile, i.e., it has a conical front area 64 that tapers to a point.

[0176] Furthermore, there is also an inside stop face 65, which is designed to be approximately cylindrical in the exemplary embodiment shown here.

[0177] Apart from that, the sealing ring 60 forms an axial ring stop 66, which is in contact with a respective axial contact face on the head of the stopper-type sealing closure 10.

[0178] According to FIG. 16, the end stop 63 is shifted as far as possible toward the left in the axial direction into the area of the sealing closure 10, while now the sealing ribs 7 that are directed radially outward, as described previously, are in contact with this axial stop 63 on the right side in the axial direction.

[0179] The sealing ribs are each approximately round, profiled, ribbed bodies, which are molded in one piece at the factory using the material of the sealing ring 60 and have grooves that narrow the cross section between them.

[0180] All other embodiments, such as those mentioned in the description of FIG. 10 ff., are of course also claimed according to the invention.

[0181] As described above, an expansion pressure 11, which is directed radially outward, then acts on the inner sleeve 12 in the direction of the arrow 13 in the interior of the conical inclination 17 of the inner sleeve 12 and is thus transferred in the radial direction via the sleeve wall 67 of the stopper-type sealing closure 10 to the novel sealing ring 60, which is thus in sealing contact with the inside circumference of the outer sleeve 2 in two mutually orthogonal directions.

[0182] This ensures that the tight and sterile region is shifted as far to the outside as possible into the sealing ring 60 in the axial direction, because the sealing location 62 is situated at the farthest possible axial outer position of the sealing ring 60 and only thenfollowing that in the axial directionis it connected to the sealing ribs 7 provided for the radial seal.

[0183] This is in contrast with the exemplary embodiment according to FIG. 1 because in this embodiment and unprotected inner region of the outer sleeve is present outside of the sealing area and is no longer present in the exemplary embodiment according to FIG. 14 ff.

[0184] In the exemplary embodiment according to FIG. 17, a different form of the sealing ring 60 is proposed, identified here as sealing ring 60a.

[0185] This exemplary embodiment is characterized in that the sealing ring 60a no longer has a cylindrical contact face 65 but instead this contact face 68 is now designed with a structure.

[0186] The structured contact face results in a reduction in the wall thickness 67 in comparison with FIG. 16, which shows clearly that the spring action of the sleeve wall 67 is increased and it is more capable of transferring the expansion pressure 11 exerted in the direction of the arrow 13 to the sealing ring 60a, which thus experiences a much greater deformation in the radial direction outward.

[0187] The sealing pressure and the sealing effect of the sealing ring 60a are thus also improved in FIG. 17.

[0188] FIG. 18, in modification of the exemplary embodiment according to FIG. 17, shows a different form of a sealing ring, which is therefore referred to as sealing ring 60b. This exemplary embodiment is characterized in that the sealing ring 60b is molded together with the material of the stopper-type sealing closure 10 as one part in a two-component process as a one-piece part at the factory, but with a different (softer) modulus of elasticity.

[0189] It thus forms an integrated body in the sealing closure 10 so that in this exemplary embodiment the sleeve wall 67 is completely omitted and the sleeve wall 67 is then formed by the inside wall of the sealing ring 60b itself.

[0190] This ensures that the expansion pressure 11 is exerted directly on the inside wall of the sealing ring 60b in the direction of the arrow 13, so the sealing ring is particularly sensitive to deformation directed radially outward.

[0191] FIG. 19 shows the exemplary embodiment according to FIG. 17 in an enlarged diagram where it can be seen that the sleeve wall 67 is designed as a double cone.

[0192] The exemplary embodiments according to FIGS. 19 and 17 thus agree with regard to the fact that there is a double-conical receiving opening 15. It consists of a first conical part 69, a cylindrical part 70 and another conical part 71 connected thereto in the axial direction. Accordingly, the sleeve wall 67 is designed with gradations with respect to the wall thickness in its axial extent.

[0193] According to the diagram in FIG. 19, the sleeve wall is initially designed with a conical taper, namely by the cone angle W and then it is designed to be cylindrical with a cylindrical part 70 and again forms a conical part 71 in the axial extension beyond the cylindrical part 70, this cone part also having the cone angle W, where W is greater than W.

[0194] Due to this double-conical design (W cylinder W), this yields the advantage that the expansion pressure in the direction of the arrow 13 is transferred in particular to the internal area of the sealing ring 60, especially in the areas 70 and 71, and thus there is a concentration of the expansion pressure in the direction of the arrow 13 on the inside circumference of the sealing ring 60, which is therefore deformed radially outward only essentially in this area, while the axial sealing location 62 remains unaffected by this expansion pressure, which is directed radially outward.

[0195] This ensures that the sealing force acts mainly on the radial sealing ribs 7 and less on the axial sealing location 62.

[0196] It is possible to provide that the cone angle 18 deviates from the cone angle of the bottom sleeve 24 by an amount X (which is a positive or negative even number).

[0197] In all application cases, this results in the desired expansion of the radially deformable sealing part 53, on the outside circumference of which the elastomerically deformable sealing ribs 7, 37 are integrally molded.
