Definitions

  • the present invention relates to a closure lid according to the preamble of claim 1 and to a container closure with such a closure lid according to the preamble of claim 1.
  • Such a container closure and such a closure cover for the container neck of a container closure is known from DE-U-299 28 541.
  • This publication also describes how such container closures or closure lids are used to seal the container in the closed position of the closure lid or, when the closure lid is rotated in the opening direction before the final release or removal of the closure lid from the container neck, relieves pressure due to the container overpressure still present achieve so that a pressurized lifting of the sealing cover can be avoided with the risk of scalding hot cooling water spurting out.
  • This prior art also describes a phenomenon of the usual container closures or closure lids, which is referred to as the so-called champagne cork effect.
  • the sealing ring can remain at higher internal pressures, despite the radially inward and this inherent tension in the annular groove, even in contact with the inner wall of the container neck when the sealing ring is out of the area in the unscrewing direction of the sealing cap the sealing surface in the area of Nozzle extension reached.
  • the sealing ring is lifted radially outwards from the groove base of the ring groove by the internal pressure of the container, so that after a further unscrewing of the closure cap, the above-mentioned sparkling wine cork effect occurs due to sudden pressure relief.
  • the object of the present invention is therefore to design a closure cap for the container neck of a container closure and a container closure of the type mentioned in the introduction in such a way that the phenomenon of the so-called sparkling wine cork effect is avoided from the outset by radially lifting the sealing ring off the base of the groove, thus relieving the pressure inside the container is reached before reaching the open position of the closure cover.
  • the features specified in claim 1 are provided for a closure cover for the container neck of a container closure and the features specified in claim 14 for a container closure.
  • the measures according to the invention ensure that when the sealing ring is removed from the sealing surface of the Container socket comes free and gets into the socket extension, the sealing ring can either deflect in the axial direction in certain areas of its ring circumference when the excess pressure prevailing inside the container, so that the sealing ring deforms axially asymmetrically, or is already deformed in the axial direction due to the design of the ring groove limitation , and thus at these circumferential areas rather reaches the area of the nozzle extension and thus partially and prematurely clears a ventilation path.
  • This axial deformation or deformation of the sealing ring not only requires a pre-venting path but also prevents the sealing ring from lifting radially outward from the groove base of the ring groove, so that the phenomenon of the champagne cork effect cannot even arise. In this way, total pressure equalization can be achieved even with a relatively high internal pressure in the container before the closure cover has reached its fully open position.
  • the features specified in claim 2 are provided, as a result of which the sealing ring is already given a correspondingly deformed installation position. This leads to the further advantage of reduced frictional resistance when screwing in and loosening the closure lid on or from the container neck.
  • the features specified in claim 3 are provided.
  • the support ribs can be arranged or designed according to the features of claim 4 and / or 5 and / or 6. In normal operation, the support ribs provide a linear support for the sealing ring within the ring groove and can either fix the sealing ring deformed or, in the event of overpressure in the interior of the container, allow sufficient axial movement of the sealing ring between adjacent support ribs during the unscrewing movement of the closure lid.
  • a further embodiment results from the features of claim 7 and in connection therewith possibly the features of claims 8 and / or 9.
  • a further embodiment results from the features of claim 10 and in an embodiment, if necessary, from the features of claim 11 and / or 12.
  • the axial mobility or pre-shaped fixing of the sealing ring is provided by differently designed recesses or depressions of the ring web contact surface (s).
  • FIG. 1 shows a schematic perspective illustration of the inner part of a closure cover for the container neck of a container closure, according to a first exemplary embodiment of the present invention
  • FIG. 1 shows a container closure from a closure lid according to FIG. 1, which is introduced into a container socket, in a state section when the closure lid is unscrewed from the container socket,
  • FIG. 3 shows a representation corresponding to FIG. 2, however according to a second embodiment of the present invention
  • Figures 4A and 4B show a section along the line IVA-IVA of Figure 1 and a section along the line IVB-IVB of Figure 4A, according to a third embodiment of the present invention
  • FIGS. 5A and 5B show a representation corresponding to FIGS. 4A and 4B, but according to a fourth exemplary embodiment of the present invention.
  • FIGS. 1 and 2 and 3 each show, in two embodiments, a substantially rotationally symmetrical container closure 10, which has a container socket 11 and a closure cover 12 or 12 'screwed onto it.
  • the tank neck 11 has a narrow neck section 13 on the underside, which is connected to an opening in a tank, not shown, preferably a cooler for internal combustion engines.
  • a tank not shown, preferably a cooler for internal combustion engines.
  • an enlarged neck section 14 is provided, which is connected to the lower neck section 13 via a conical intermediate section (ramp) 15.
  • the container neck 11 is provided with an external thread 16, through which the closure cover 12, 12 'is screwed with an internal thread 17, i.e. can be screwed and unscrewed.
  • the closure lid 12 or 12 ' has a cap-shaped outer cover part 21 which engages over the container neck 11 and with the internal thread 17 for screwing on and off Container neck 11 is provided.
  • the closure cover 12, 12 ' has a pot-shaped cover inner part 22, which is shown in perspective in FIG. 1, or an inner cover part 22'.
  • the inner cover part 22, 22 ' is inserted with an upper edge 23 into an inner groove on the outer cover part 21 so that the outer cover part 21 and the inner cover part 22, 22' can rotate relative to one another.
  • An annular groove 26 adjoins the basket part 24 provided with the upper edge 23, into which an elastomeric sealing ring 27 in the form of an O-ring is inserted.
  • the annular groove 26, 26 ' is delimited on the one hand by an annular web 28, 28' on the outside of the cover part and by an annular web 29, 29 'pointing towards the container.
  • the outer diameter of the ring webs 28, 28 'and 29, 29' is smaller than the outer diameter of the sealing ring 27 which bears against the groove base 31 of the annular groove 26, 26 'under radially inward bias.
  • the ring web 28 on the outer part of the cover is provided on its contact surface 32 with support ribs 33 projecting axially in the direction of the ring web 29 on the inside of the container.
  • the length of the support ribs 33 corresponds to the radial width of the contact surface 32 of the ring web 28 on the cover outer part side.
  • the support ribs 33 are very narrow in the circumferential direction and also have a relatively small axial height, this axial height being determined in the exemplary embodiment so that the clear width between Support rib 33 and opposite surface 34 of the inner ring web 29 is approximately equal to the thickness of the O-ring 27.
  • four support ribs 33 are provided which are uniformly distributed over the circumference of the contact surface 32 of the ring web 28 on the cover outer part side.
  • each ring web 28 ', 29' has a pair of diametrically opposed support ribs 33 and 38, respectively, which face each other axially, that is, project into the annular groove 26.
  • the pairs of support ribs 33 and 38 are arranged offset by 90 ° to one another. The sealing ring 27 'is thus deformed in the annular groove 26'.
  • the height of the supporting ribs 33 and 38 is such that the clear width between the supporting rib 33 or 38 and the opposite surface 37 of the ring web 29 'on the inside of the container or between the supporting ribs 38 and opposite surface 32' of the ring web 28 'on the outside of the lid is approximately equal to the thickness of the Is O-ring 27 ', the sealing ring 27' is fixed in the corresponding circumferentially corrugated deformation in the annular groove 26 '.
  • the length of the support ribs 33 and 38 corresponds to the support ribs 33 of the first embodiment.
  • the sealing ring 27 reaches the region of the conical or ramp section 15 of the inner circumference of the container neck 11, so that the compression or the compression of the sealing ring 27 is reduced. Because of the upcoming Overpressure in the interior of the container, the sealing ring 27 is now moved axially within the annular groove 26, specifically in the areas that lie between the support ribs 33. Due to this uneven contact surface 32 of the ring web 28 on the outside of the cover part, the axial movement of regions of the sealing ring 27 results in an asymmetrical deformation, so that, as shown in FIG.
  • a connecting path 36 in the deformed partial regions of the sealing ring 27 passes past the ramp section 15 into the nozzle extension and thus a venting path results before the entire sealing ring 27 reaches the nozzle extension or the upper nozzle section 14. Since the asymmetrical deformation of the sealing ring 27 results in a premature venting path, which results in a reduction in pressure, the phenomenon of the rear blowing of the sealing ring 27 and thus its lifting off from the groove base 31 is avoided.
  • the sealing ring 27' also reaches the region of the conical or ramp section 15 of the inner periphery of the inner periphery of the container neck 11, so that the compression or the compression of the sealing ring 27 'is reduced becomes. Since the sealing ring 27 'is preformed in the circumferential direction within the annular groove 26' between the two uneven contact surfaces 32 'and 34 of the two ring webs 28' and 29 ', this results, as shown in FIG.
  • FIGS. 4A and 4B show an embodiment of an uneven contact surface 32 "of the ring web 28" on the outside of the cover part in such a way that two diametrically opposite recesses 41 are formed in the contact surface 32 ".
  • the two identically mirrored recesses 41 have curved convex inner boundary lines 42. This means that in the area of these recesses 41 the sealing ring 27 can deform axially asymmetrically in the area of these recesses 41 when the closure cap 12 "is released from the container socket 11, so that a pressure relief path is created in these areas during the unscrewing movement.
  • a circumferential groove 43 is provided adjacent to the bottom of the groove and the contact surface 32 ′′.
  • FIGS. 5A and 5B show a further exemplary embodiment of an uneven contact surface 32 ′′, in which this is also provided with a recess 51 which, like the recess 41 according to FIGS. 4A and 4B, radially from the outer circumference of the contact surface 32 ′′ and 32 ′′
  • the depth of the respective recess 41 or 51 is relatively small.
  • the recess 51 is approximately sickle-shaped when viewed in plan view, the distance between the circular inner boundary line 52 and the outer peripheral edge of the contact surface 32 "'decreasing symmetrically , In one area is the distance between the Boundary line 52 and the outer circumference of the contact surface 32 "'maximum equal to the radial width of the contact surface 32"' and zero in the diametrically opposite area.
  • the boundary line 52 is circular, the circle of the boundary line 52 correspondingly eccentric to the circle of the outer circumference of the contact surface 32 ′ ′′.
