Description

[0001] The invention relates to a sanitary insert part, in particular a jet regulator, with a preferably circumferential contact surface formed on a housing part, which represents a stop for a connecting movement, in particular an insertion movement or screwing movement, of the sanitary insert part.

[0002] The invention further relates to a use of a sanitary insert, in particular a jet regulator, wherein the contact surface is brought into operative relationship with an edge break.

[0003] The invention also relates to a sanitary fitting with a sanitary insert, in particular a jet regulator.

[0004] Finally, the invention relates to a set comprising a disassembly tool and a sanitary insert part, in particular a jet regulator, and a sanitary fitting, wherein the sanitary insert part can be detached from the sanitary fitting by means of the disassembly tool, in particular unscrewed and / or mounted, in particular screwed, onto the sanitary fitting.

[0005] Aerators or, more generally, sanitary inserts with a contact surface that interact, for example, with the inside of a sanitary fitting are known from practice, for example to form a transition between the sanitary fitting and the aerator in a screwed-in state.

[0006] The invention is based on the object of improving the performance characteristics of a sanitary insert.

[0007] To achieve the stated object, the invention proposes the features of claim 1. In particular, according to the invention, a sanitary insert part with a contact surface formed on a housing part, which represents a stop for a connecting movement, in particular an insertion or screwing movement, of the sanitary insert part, is proposed according to the invention that this contact surface is formed at the level of at least one annular region of an outlet structure (or even at the level of an outlet structure) of the sanitary insert part and is arranged on the sanitary insert part in such a way that it can interact with an edge break on an outlet of a jet regulator receptacle of a sanitary fitting.

[0008] A connecting movement can, for example, also be a snapping, a pressing, a plugging, a turning-plugging (e.g. bayonet lock) or a combination of one or more of these connecting movements with each other and / or with other connecting movements.

[0009] By forming the contact surface at the level of at least one ring area of ​​an outlet structure, a hidden sanitary insert part can be formed which, for example, terminates with a sanitary fitting with a radially outer ring area and / or can be submerged with its predominant part in a sanitary fitting.

[0010] The edge break can be characterized, for example, as the result of a non-dimensionally accurate machining step and / or as the result of burr removal. Accordingly, the edge break can be, for example, a bevel, such as a chamfer, and / or a transition radius. Accordingly, it can be provided, for example, that the contact surface also has a bevel, in particular a chamfer, which can interact with the edge break.

[0011] A significant advantage is that, for example, no additional processing and / or manufacturing steps are required to generate the interaction between the sanitary fitting and the sanitary insert, in particular the aerator, via the appropriately arranged contact surface. The performance characteristics are thus improved. Another advantage is that corresponding aerators or, more generally, sanitary inserts can be easily inserted into existing sanitary fittings. This allows for the use of standardized receptacles for aerators and other sanitary inserts.

[0012] The contact surface can, for example, be arranged particularly advantageously at the edge break at the outlet of the jet regulator holder of the sanitary fitting in such a way that a fluidic sealing can be achieved between the sanitary insert part, in particular the jet regulator, and the sanitary fitting.

[0013] Because the contact surface also represents a stop for the connecting movement, in particular the insertion or screwing movement, of the aerator or other sanitary insert part, a reversible intended use, in which the sanitary insert part, in particular the aerator, is completely screwed into the sanitary fitting, can advantageously be achieved. Improper screwing and / or unscrewing of the sanitary insert part into or out of the sanitary fitting, which could, for example, destroy threads of the sanitary insert part and / or the sanitary fitting, can thus also be advantageously largely prevented.

[0014] An arrangement at the level of at least one annular region of the outlet structure can be characterized, for example, in that the outlet structure, at least in the annular region, essentially does not protrude and does not sink when the contact surface is aligned, coincides or otherwise interacts with the end of the sanitary fitting in the direction of flow.

[0015] The outlet structure can extend inward from the ring area in a convex or concave manner, a complex shape, or a flat, even stepped configuration. By arranging it at the level of the outlet structure, the edge can be concealed, allowing a seal to be concealed. This creates an attractive visual appearance. In an advantageous embodiment, the outlet structure can be flat on the downstream side, but a coin slot (with a bulbous outlet structure) is also conceivable. A slightly protruding drip edge can also be used for improved flow separation.

[0016] Preferably, the contact surface is designed to be circumferential. This advantageously allows, for example, the sanitary insert, in particular the aerator, to interact with the sanitary fitting at every contact point along the entire circumferential direction. The formation of creepage distances can thus be prevented.

[0017] Alternatively or additionally, the features of the subordinate claim directed to a sanitary insert, in particular a jet regulator, are provided according to the invention to achieve the stated object. In particular, to achieve the stated object, in a sanitary insert, in particular a jet regulator, in particular an already mentioned and / or claimed sanitary insert, in particular a jet regulator, it is proposed according to the invention that the contact surface be formed at least partially by an elastic material molded onto the housing part.

[0018] This allows for a captive arrangement of a sealing body made of an elastic material. This can simplify assembly.

[0019] The elastic material can be an elastomer, for example. This can enable easy contact and / or sealing even on uneven or rough surfaces.

[0020] The elastic material can be formed, for example, by injection molding.

[0021] The housing part and the elastic material formed thereon can, for example, form a lowermost outer circumferential edge of the sanitary insert part, in particular the jet regulator.

[0022] Alternatively or additionally, to achieve the stated object, it is proposed that the contact surface be at least partially formed with a non-circular elastic material having a cord cross-section, preferably shaped to match the outer contour of the sanitary insert. A non-circular, for example, non-round, contour makes it possible to fix the elastic material in a form-fitting manner and / or to form or line suitable contact surfaces. A cord cross-section can be characterized, for example, by being perpendicular (at every point) to the direction of travel of a circumferential structure.

[0023] Particularly advantageously, the aerator or other sanitary insert part can thus, due to a certain elasticity of the elastic material, already during screwing and / or in the screwed-in state, conform to an external structure of the sanitary fitting, for example, to the edge break, which forms a contact point of the contact surface. Another advantage is that other sections of the aerator or other sanitary insert part, for example, the outlet structure, can be made of a different material, which in turn can generate a high degree of variability in the material selection.

[0024] Furthermore, it can be provided, for example, that the elastic material is designed as a single piece with an outlet structure of the jet regulator or other sanitary insert and the housing part. The outlet structure forms, for example, a final section of the jet regulator or other sanitary insert, from which a water stream emerges. For example, it can be provided that the elastic material thus forms jet outlet holes of the outlet structure.

[0025] A particularly advantageous feature is that, in addition to or as an alternative to the aforementioned advantage of the contact surface's conformability to, for example, the edge of the sanitary fitting, such a variant allows the selection of elastic materials that, for example, do not attract stubborn limescale deposits. This prevents the jet outlet holes from becoming clogged with limescale deposits, for example, and increases the longevity of the jet regulator or other sanitary fitting.

[0026] In an advantageous embodiment, it can be provided that the elastic material is a thermoplastic.

[0027] Thus, it is particularly advantageous, for example if the elastic material is designed as one piece with the outlet structure, to produce it using a thermoplastic material, for example by means of injection molding, in particular for large quantities.

[0028] Alternatively or additionally, the elastic material can be silicone. This makes it easier to comply with drinking water regulations, for example.

[0029] Silicones offer the essential advantage of physiological compatibility, particularly in the area of ​​aerators and the associated constant contact with drinking water. Furthermore, silicones remain (thermo)mechanically stable over a very wide temperature range, allowing even hot and very cold water to pass through the spout structure safely, as is common in sanitary fittings.

[0030] In an advantageous embodiment, it can be provided that the contact surface rests on the sanitary fitting in a proper use and is shaped such that at least at one contact point located within the contact surface an orientation of the contact surface at an angle to an axial direction and to a radial direction is achieved.

[0031] The axial direction can be defined, for example, by a longitudinal direction of the jet regulator or other sanitary insert.

[0032] By a corresponding orientation of the at least one contact point within the contact surface at an angle to the axial direction and to the radial direction, which in particular lies at a right angle to the axial direction, a sealing, for example hermetic and / or in particular fluidic, of gap dimensions, for example between and / or at a transition between the sanitary fitting and the sanitary insert part, in particular a jet regulator, can be generated in a particularly advantageous manner.

[0033] Another advantage is that, for example, water penetration into the gaps, for example, due to lateral drainage or capillary action, can be largely prevented. Water penetration into the corresponding gaps can, for example, promote the formation of limescale deposits between the sanitary insert, in particular the aerator, and the sanitary fitting, which in turn makes it difficult to screw the aerator or other sanitary insert into or out of the sanitary fitting without causing any damage.It is therefore also particularly advantageous that the corresponding orientation of the contact surface and the resulting, particularly fluidic, sealing in the axial and radial directions can significantly reduce the likelihood of limescale deposits forming in hard-to-reach spaces and facilitate problem-free screwing in and / or unscrewing of the jet regulator or other sanitary insert part.

[0034] Preferably, the orientation of the contact surface is achieved at an angle to the axial and radial directions at each contact point within the contact surface. This advantageously allows, for example, a circumferentially consistent, preferably fluidically sealing, operative connection to be generated between the sanitary insert, in particular the jet regulator, and the sanitary fitting.

[0035] In a further advantageous embodiment, it can be provided that ventilation channels are formed on the sanitary insert part, in particular the jet regulator.

[0036] The ventilation channels, for example, introduce air into a mixing stage. This makes it possible to add air to the water flow that ultimately passes through the aerator or other sanitary fitting, which is particularly beneficial because it can reduce water consumption, for example.

[0037] In a further advantageous embodiment, it can be provided that a tool attachment is formed on the housing part for introducing a torque for screwing in and / or unscrewing the jet regulator or the other sanitary insert part.

[0038] The tool attachment can be formed, for example, by at least one ventilation channel, such as a ventilation channel already described. The tool attachment can also be formed, for example, in the outlet structure.

[0039] Particularly advantageous is the aerator, which, for example, has an external thread that is screwed into an internal thread of the sanitary fitting, so it can be easily installed initially or replaced in the event of wear and / or repair.

[0040] In a further advantageous embodiment, it can be provided that the contact surface extends radially outside an axial projection of a threaded area.

[0041] This can be particularly advantageous in significantly reducing the likelihood of water penetrating a gap between the plumbing fixture and the aerator below the threaded area, for example, as already mentioned, due to lateral drainage of the water and / or capillary action. If water gets into the threaded area and thus into the threads between the aerator and the plumbing fixture, limescale deposits could form, preventing the sanitary insert, especially the aerator, from being screwed in and / or unscrewed without damaging it.

[0042] In an advantageous embodiment, it can be provided that the sanitary insert part, in particular the jet regulator, has at its axial end a radially extending outlet structure which, at least in an outer ring region in the screwed-in state of the sanitary insert part, in particular the jet regulator, is matched to an axial end of the sanitary fitting and / or does not protrude outwards.

[0043] This means, for example, that the sanitary insert, in particular the jet regulator, lies flat against the sanitary fitting.

[0044] What is particularly advantageous is that even if water flows sideways from the outlet structure, there is no increased risk of it getting into the gaps between the sanitary insert, in particular the aerator, and the sanitary fitting.

[0045] For example, it can be provided that an axial extension of the outlet structure, for example an inner boundary of the outlet structure, is set in a certain relationship to a dimension or the arrangement of the contact surface.

[0046] In a further advantageous embodiment, it can be provided that a thread corresponding to a counter thread of the sanitary fitting is formed for screwing the sanitary insert part, in particular the jet regulator, into or out of the sanitary fitting.

[0047] For example, it can be provided that the sanitary insert, in particular the aerator, has an external thread, via which the sanitary insert can be screwed into and / or out of a matching internal thread of the sanitary fitting. Furthermore, it can be provided, for example, that the sanitary insert, in particular the aerator, has an internal thread, via which it can be screwed into and / or out of a matching external thread of the sanitary fitting.

[0048] It is therefore particularly advantageous to generate a sufficiently stable and, at the same time, easily detachable force-locking connection between the sanitary insert part, in particular the jet regulator, and the sanitary fitting.

[0049] In an advantageous embodiment, it can be provided that the sanitary insert part, in particular the jet regulator, rests against an inner side of the sanitary fitting via the contact surface during intended use.

[0050] As already mentioned, the intended use can, for example, define a state in which the sanitary insert part, in particular the jet regulator, is completely and thus screwed into the sanitary fitting up to the stop.

[0051] It is particularly advantageous if, for example, the contact surface, which is preferably formed by the elastic material described above, is arranged at the edge break and thus at the outlet of the aerator holder in such a way that it also rests against the inside of the sanitary fitting. Even if, for example, a small amount of water enters a gap at the transition between the sanitary fitting and the sanitary insert, in particular the aerator, it can be prevented from reaching higher areas, such as threaded areas.

[0052] In an advantageous embodiment, it can be provided that the contact surface, which in a normal use rests against the sanitary fitting, is separated from an end surface forming an outlet structure by a transition describing an acute angle.

[0053] For example, it can be provided that the contact surface with the end face, when fully screwed in, forms an angle of less than 90° along the radial direction and with the axial direction. Such an angle can, for example, help to hinder or prevent water from creeping into a gap formed by a receiving sanitary fitting. It is particularly advantageous if the acute angle is aligned with the edge break. This can, for example, enable easy snug fitting to the sanitary fitting.

[0054] The pointed structures of the profile can advantageously allow the jet regulator to be countersunk into the sanitary fitting or to be aligned with it without any protrusion or practically without any protrusion (at least in an outer lateral or radial edge area), without the need for complex remachining at the transition between the sanitary fitting and the sanitary insert part, in particular the jet regulator.

[0055] Alternatively or additionally, to achieve the stated object, the features of the independent claim directed to a use of an already claimed sanitary insert, in particular a jet regulator, are provided according to the invention. In particular, the invention proposes that the contact surface be brought into operative relationship with an edge break. This can enable a simple closure of a gap between the inserted jet regulator and the receiving sanitary fitting, in particular to prevent seepage or penetration of water escaping from the sanitary insert, in particular the jet regulator, and creeping laterally along a surface of the sanitary insert.

[0056] The advantages already mentioned can thus be realized particularly advantageously.

[0057] Alternatively or additionally, to achieve the stated object, the invention provides the features of the independent claim directed to a sanitary fitting with an already claimed sanitary insert, in particular a jet regulator. In particular, the invention proposes that the or an elastic material be designed such that, during intended use, in which the sanitary insert, in particular the jet regulator, is fully screwed into an internal thread of the sanitary fitting with an external thread, a transition between the contact surface of the sanitary insert, in particular the jet regulator, and an inner side of the sanitary fitting is fluidically sealed by the elastic material.

[0058] The elastic material can be formed, for example, from an elastomer body, for example a silicone elastomer body or from a thermoplastic plastic elastomer body.

[0059] Particularly advantageously, the elastic material can thus conform to the peripheral edge or edges of the sanitary fitting. The peripheral edge can be, for example, a manufacturing-related bevel, in particular a chamfer, or a transition radius. It is particularly advantageous that the transition between the sanitary fitting and the sanitary insert, in particular the aerator, can be fluidically sealed in the axial and radial directions due to the orientation of the contact surface at an angle.

[0060] This can be particularly advantageous in preventing, for example, water from seeping in and thus a gap from clogging at the transition between the sanitary fitting and the sanitary insert part, in particular the jet regulator.

[0061] Alternatively or additionally, to achieve the stated object, the features of the independent claim directed to a set are provided according to the invention. In particular, to achieve the stated object in a set comprising a disassembly tool and an already mentioned and / or claimed sanitary insert part, in particular a jet regulator, and a sanitary fitting, wherein the sanitary insert part can be unscrewed from the sanitary fitting and / or screwed onto the sanitary fitting by means of the disassembly tool, it is proposed according to the invention that the disassembly tool is designed to apply a torque to a tool attachment of a housing part for screwing in and / or unscrewing the sanitary insert part.

[0062] This makes it possible to create a point of attack for a tool that is frequently flowed through or overflowed and has little tendency to calcification.

[0063] In a further advantageous embodiment, it can be provided that the disassembly tool is designed to engage in at least two channel walls of the housing part of the sanitary insert part, in particular the jet regulator, which channel walls form the tool attachment and delimit ventilation channels.

[0064] The ventilation channels thus offer a highly advantageous multifunctional capability, namely the function of supplying air into a mixing stage and thus into a water flow and / or the function of the tool attachment.

[0065] The invention will now be described in more detail using exemplary embodiments, but is not limited to these exemplary embodiments. Further exemplary embodiments arise from combining the features of one or more claims with one another and / or with one or more features of the exemplary embodiment.

[0066] It shows in a highly simplified representation Fig. 1 a two-dimensional representation of a first variant of a sanitary insert using the example of a jet regulator with outlet structure, a radially outwardly extending, bevelled contact surface and an O-ring, Fig. 2 a two-dimensional representation of a second variant of a sanitary insert using the example of a jet regulator with outlet structure, a radially outwardly extending, bevelled contact surface and a shaped seal, Fig. 3 a two-dimensional representation of a third variant of a sanitary insert using the example of a jet regulator with an outlet structure, a radially outwardly extending, bevelled contact surface formed on the outlet structure, Fig. 4 a two-dimensional representation of a fourth variant of a sanitary insert using the example of a jet regulator with an outlet structure, a radially outwardly extending, bevelled and integrally formed contact surface on the outlet structure, Fig. 5 a sanitary insert part using the example of a jet regulator in a partial section, wherein the jet regulator according to Fig. 1 is designed, Fig. 6 a sanitary insert part using the example of a jet regulator in a partial section, wherein the jet regulator according to Fig. 3 is designed, Fig. 7 a jet regulator screwed into a jet regulator receptacle of a sanitary fitting as an example of a sanitary insert part in a side view and in a full section, wherein the jet regulator according to Fig. 3 is designed. Fig. 8 a jet regulator screwed into a jet regulator receptacle of a sanitary fitting as an example of a sanitary insert part in a side view in a full section, wherein the jet regulator according to Fig. 1 is designed, Fig. 9 a jet regulator screwed into a jet regulator holder of a sanitary fitting as an example of a sanitary insert part according to Fig. 8 in a perspective bottom view,

[0067] Fig. 1 shows a jet regulator, designated as a whole by 1, as an example of a sanitary insert with an outlet structure 3 formed on the jet regulator 1, which forms a water outlet 2. The outlet structure 3 is formed at an axial end 13 of the jet regulator 1 and extends in the radial direction 14. It can thus be said that the outlet structure 3 forms an end face 15 of the jet regulator 1.

[0068] Further embodiments may have additional parts on the jet regulator 1 shown, which are detachably or loosely connected to it, for example screw sleeves or mouthpieces.

[0069] The aerator 1 from Fig. 1 has a threaded area 5 on a housing part 4 with, in this embodiment, an external thread 6. This serves to screw the jet regulator 1 into a corresponding internal thread 7 of a sanitary fitting 8 (see Fig. 7, Fig. 8, Fig. 9) screw in and / or unscrew.

[0070] It can therefore be said that on the jet regulator 1, for screwing in and / or out into the sanitary fitting 8, a thread 10 is formed corresponding to a counter thread 9 of the sanitary fitting 8 (see Fig. 7, Fig. 8, Fig. 9).

[0071] Furthermore, the jet regulator 1 is Fig. 1 is formed with a contact surface 11 extending radially outside an axial projection of the threaded area 5 and thus radially outside the external thread 6.

[0072] The contact surface 11, which directly borders radially on the outlet structure 3, is bevelled in this embodiment and forms a chamfer 12. This geometric design results in the contact surface 11, as in Fig. 7, Fig. 8 and Fig. 9, represents a stop for a screwing-in movement of the jet regulator 1.

[0073] In this embodiment, the contact surface 11 is integrally connected to the housing part 4 and the outlet structure 3 and is made of solid plastic.

[0074] Furthermore, it can be seen that an O-ring 16 is formed on the jet regulator 1, between the contact surface 11, the outlet structure 3, and the threaded area 5 with the external thread 6. This O-ring 16 acts as a fluid seal to prevent the ingress of water during intended use and thus as soon as the jet regulator 1 with the external thread 6 is fully screwed into the internal thread 7 of the sanitary fitting 8 (cf. Fig. 8, Fig. 9).

[0075] It can be seen that the contact surface 11 is formed at the level of at least one annular region 32 of the outlet structure 3. The outlet structure 3 continues the annular region 32 radially inward in a flat manner.

[0076] Fig. 2 shows a further embodiment of a jet regulator 1. Components and functional units that are functionally and / or structurally similar or identical to the preceding embodiment are designated by the same reference numerals and are not described separately again.

[0077] In contrast to the previous embodiment, here, for fluidic sealing, a shaped seal 17 is arranged on the jet regulator 1 instead of the O-ring 16. This shaped seal 17 touches the contact surface 11 in sections, and in contrast to the O-ring 16 ( Fig. 1) easier to install and enables an improved sealing effect.

[0078] It can be seen that the elastic material 18 has a non-circular cord cross-section with which it is adapted to an outer contour of the jet regulator 1.

[0079] The embodiment according to Fig. 3 differs from the preceding embodiments in that the contact surface 11 is at least partially formed by an elastic material 18 molded onto the housing part 4. In this embodiment, the elastic material 18 is a silicone 19 or a thermoplastic elastomer (TPE) 20. The outlet structure 3 also consists of a hard material.

[0080] It can thus be said that the elastic material 18 is a thermoplastic 21 and / or a silicone 19.

[0081] The fluidic seal is not provided by an O-ring 16 ( Fig. 1) or a molded seal 17 ( Fig. 2), but by the chamfer 12 of the contact surface 11 itself.

[0082] Fig. 4 shows, in contrast to the embodiment according to Fig. 3 shows a jet regulator 1, whose contact surface 11 is formed integrally with the outlet structure 3 and is made of elastic material 18, in this embodiment solid rubber. In this embodiment, too, fluid sealing is achieved via the chamfer 12 of the contact surface 11.

[0083] Fig. 5 and Fig. 6 show embodiments of the jet regulator 1 according to Fig. 1 and Fig. 3 in a partial section with outlet structure 3, contact surface 11, O-ring 16 ( Fig. 5), elastic material 18 of the contact surface 11 ( Fig. 6) and the threaded area 5 with external thread 6 formed on the housing part 4.

[0084] In Fig. 6 shows that the contact surface 11 is arranged at the level of an annular region 32 of the outlet structure 3. The annular region 32 has a drip edge 33.

[0085] Fig. 7 shows an embodiment of the intended use of the jet regulator 1 according to Fig. 3. The aerator 1 is screwed completely into the internal thread 7 of the sanitary fitting 8 via the external thread 6. The contact surface 11 represents a stop for the screwing-in movement of the aerator 1. For screwing in and / or unscrewing the aerator 1, a tool attachment 29 is formed on the housing part 4. In this embodiment, this tool attachment 29 is formed by channel walls 31 delimiting ventilation channels 30, into which a disassembly tool (not shown in detail) can engage to apply a torque.

[0086] It can also be seen that the contact surface 11 on the jet regulator 1 is arranged such that it interacts with an edge break 22 at the outlet of a jet regulator receptacle 23 of the sanitary fitting 8.

[0087] In this intended use shown, the contact surface rests on the sanitary fitting 8 and is shaped such that an orientation at an angle to an axial direction 25 and the radial direction 14 is achieved at each contact point 24 located within the contact surface 11.

[0088] It can also be seen that the jet regulator 1 rests on the sanitary fitting 8 via the contact surface 11, in this embodiment an inner side 27 of the sanitary fitting 8.

[0089] Furthermore, it can be seen that the outlet structure 3, in the screwed-in state shown, is aligned with an axial end 26 of the sanitary fitting 8 in an outer annular region of the jet regulator 1 and does not protrude outward. The contact surface 11 adjacent to the sanitary fitting 8 is separated from the end face 15 formed by the outlet structure 3 by a transition 28 defining an acute angle.

[0090] Since the contact surface 11 of the jet regulator Fig. 3, as already mentioned in Fig. 3, consists of an elastic material 18, it can be said that the transition 28 between the contact surface 11 of the jet regulator 1 and the inner side 27 of the sanitary fitting 8 is fluidically sealed by the elastic material 18. Accordingly, the contact surface 11 conforms to the shape of the edge break 22 during intended use, thereby ensuring sealability.

[0091] Fig. 8 and Fig. 9 show, in contrast to the previous embodiment, a side view ( Fig. 8) and a perspective bottom view ( Fig. 9) of the jet regulator 1 according to Fig.1 in its intended state, i.e., when screwed into the sanitary fitting 8, in a full cut. The O-ring 16 has deformed accordingly due to the force-locking connection between the aerator 1 and the sanitary fitting 8 and provides a fluidic seal.

[0092] According to the invention, in a sanitary insert part, in particular a jet regulator 1, with a preferably circumferential contact surface 11 formed on a housing part 4, which represents a stop for a screwing-in movement of the jet regulator 1, it is proposed that the contact surface 11, in a screwed-in state, rests against an edge break 22 of a sanitary fitting 8, interacts with this and is shaped such that at least one contact point 24 lying within the contact surface 11, an orientation of the contact surface 11 at an angle to an axial direction 25 and to a radial direction 14 is achieved in order to preferably fluidically seal a transition 28 between the contact surface 11 and the sanitary fitting 8.
