  • FIG. 9 shows a perspective view of the closure cap according to FIGS. 7 and 8 from below
  • FIG. 10 shows another embodiment of an expandable nut element
  • FIG. 11 shows a further embodiment of a cap.
  • the approximately hat-shaped closure cap 1 is preferably made of plastic and has a flange section 2 which comes to rest on a surface 3a surrounding the threaded connector 3.
  • an annular seal 4 is provided which, after screwing on the sealing cap 1, seals the threaded connector 3 against the escape of oil.
  • the free ends of the spring arms 7 are bent inwards to inclined surfaces 8, which merge into a horizontal section 9, which extends radially outwards.
  • a section 10 is bent inward, which also runs approximately horizontally and is slightly inclined with respect to the longitudinal axis, so that the free edge of section 10 corresponds to a section of a thread.
  • the edge of the section 10 is preferably designed to be curved in the view along the axis of the closure cap.
  • the inclined surfaces 8 When the closure cap is placed on a threaded section, the inclined surfaces 8 first come to rest on the outer circumference of the threaded connector 3, whereupon when the closure cap 1 is pressed on, the lower ends of the spring arms 7 are pressed radially outward until the engagement section 10 with the thread on the outer circumference of the Threaded connector 3 can engage. For this purpose, the free edge of the section 10 over the inner edge of the inclined surface 8 before. Then the cap is screwed on until the flange section 2 with the ring seal 4 comes to rest on the surface 3a.
  • the sealing of the threaded connector 3 can be achieved by inserting a sealing ring on the inside of the sealing cap 1, for example in the area of the web 5 'of the spring clip. be educated.
  • the seal is preferably provided on the outside of the closure cap on the flange section 2 in the form of the ring seal 4, so that the seal is independent of the diameter of the threaded connector 3 and the function of the elastically expandable nut element 5 is not hindered.
  • a nut element instead of a two-armed spring clip 5, a nut element can also be provided which has a plurality of elastically deformable arms distributed over the circumference, which are provided with one or more engagement sections.
  • the web section 5 'of the approximately U-shaped spring clip formed from a strip of spring material can serve to fasten the spring clip in the closure cap, for example by riveting or gluing.
  • the arms 7 of the spring clip are preferably additionally guided in longitudinal grooves 16 (FIG. 4) on the inner circumference of the closure cap so that they are connected to the latter in a rotationally fixed manner.
  • a hexagonal shoulder 11 can be formed on the outside of the closure cap so that a tool for screwing the closure cap can be attached.
  • the inner edge of the inclined surface 8 can also be designed as an engagement section, as is shown schematically in FIG. 3 for a plastic clip whose diametrically opposite arms 7 have triangular ribs 12 which are pressed radially outward in the direction of the arrow be able to engage with the thread.
  • Fig. 4 shows a partial longitudinal section of a plastic cap 13 along the line II in Fig. 5, in which a sealing lip 4 'is formed from plastic on the outer edge of the flange portion 2. Instead of the sealing lip 4 ', an O-ring can also be inserted into a groove in the plastic. 14 with a recess on the inside for inserting the spring clip 5 is designated. At 15, plastic projections are located at opposite points in this Acceptance designated 14, on which the web portion 5 'of the spring clip engages by pressing, so that a separate connecting element is not required.
  • lateral guide grooves for the spring arms 7 are designated by which the spring clip 5 is held against rotation in the cap 13.
  • Fig. 6 shows a 45 ° rotated sectional view along the line II-II in Fig. 5 diametrically opposite plastic lips 17, which are used only for centering a threaded connector with a smaller diameter. When placed on a threaded connector with a smaller diameter, these plastic lips 17 are pressed to the side, and they can also break away. They only serve as an introduction aid.
  • the cylindrical interior designated 18 is designed such that it can accommodate the largest diameter of a threaded connector.
  • the engagement sections 8, 10 of the spring arms 7 in the grooves 16 extend into the cylindrical cavity 18 so that they can also engage with a threaded connector of smaller diameter.
  • FIG. 7 to 9 show a preferred embodiment of a closure cap, a pin 25 being formed on the inside of the end wall 24 of the plastic cap 13 lying transversely to the longitudinal axis, onto which the spring clip 5 is attached.
  • the spring clip has a bore on the web section 5 ′ for receiving the pin 25.
  • a latching connection is preferably provided so that the spring clip attached to the pin 25 cannot fall out when handling the closure cap. It is also possible to provide a polygonal cross section of the pin instead of a round pin, so that in addition to the holding function, the spring clip is also secured against rotation relative to the cap. In addition, however, the spring clip is secured by the spring arms 7 in the grooves 16 against rotation relative to the cap.
  • FIG. 7 shows the left spring arm 7 in a starting position in which the engagement section 10 engages with the external thread of a threaded connector 3 of minimal diameter, while the right spring arm 7 in FIG. 7 is shown in a position in FIG which it engages with the thread of a threaded connector of maximum diameter.
  • FIG. 8 also shows these two end positions in a view from below in FIG. 7. lungs of the spring clip, wherein the curved edge of the engagement section 10 is also shown, which can also be seen in the perspective view of the closure cap in FIG. 9 from below.
  • the spring arms 7 are preferably approximately V-shaped in the engagement area between the inclined surface 8 and an angled section 7 ′, as shown in FIG. 7, in order to improve the elasticity in the engagement area.
  • the radially outer region of a spring core 7 can rest on the inner wall of the groove 16 if a maximum diameter of a threaded connector 3 is accommodated, as the right-hand side in FIG. 7 shows, the V-shape of the engagement section still providing sufficient elasticity for the There is an intervention on the threaded connector.
  • FIG. 10 shows a nut element 20 which can be inserted into a closure cap and which consists of a hollow, truncated cone-shaped injection molded part made of plastic.
  • a base ring 21 corresponding to the largest diameter of a threaded connector, which need not be widened when screwed on, has two or three threads on a cylindrical section on the inner circumference, so that this base ring 21 can be screwed directly onto a threaded connector with the largest diameter.
  • the circumferential surfaces 22 extending from the base ring 21 and distributed over the circumference have a thread on the inner circumference, the individual sections being separated from one another by slots 23, so that when placed on a threaded connector with a medium diameter, the edge thereof approximately in the central region of this nut element It comes into contact with what the peripheral sections 22 are pressed outward in the direction of the arrow when the nut element 20 is screwed onto the threaded connector.
  • the nut element 20 can, for example, be inserted and fixed in a plastic cap via a bayonet catch or the like.
  • An expandable nut element 20 made of plastic can also be molded directly onto a plastic cap 13.
  • An essential advantage of a sealing cap of the type described is that the sealing cap can be pressed onto the respective threaded connector due to the expandable nut element so that the flange section 2 with the circumferential seal rests on the peripheral surface of the threaded connector, after which only an additional Before screwing with one or two turns is required to tighten the sealing cap and to firmly press the flange section 2.
  • the elastically expandable nut element can also be designed as a latching element, so that the plastic cap only has to be pressed onto the threaded connector to be sealed, the catches corresponding to the threaded sections 10 engaging with the external thread of the threaded connector and the closure cap in the pressed-on position hold.
  • the flange section surrounding the closure cap is designed to be elastic and is preferably provided with a prestress.
  • 11 shows an exemplary embodiment of a flange section 2 ′ which is shaped approximately in the shape of a truncated cone and which has a molded-on sealing lip or an O-ring 4 inserted into a groove.
