Definitions

  • the invention relates to a clamping ring closure for containers made of sheet metal, such as buckets, hobbock or the like. With the features of the preamble of claim 1.
  • German utility model 19 90 800 shows a clamping ring closure, in which the closure is formed in a straight line along its length, deviating from the general curvature of the clamping ring. This also applies to a profiled bridging piece which is fixedly attached to one circumferential end of the clamping ring and slidably receives the other circumferential end of the clamping ring.
  • the movable elements of the closure are articulated on the parts so that they are movable in a plane which is perpendicular to the plane of the clamping ring.
  • the bridging piece has a locking bracket which engages in a window at the free end of the actuating lever of the closure in the closed position in order to prevent the lever from pivoting in the direction of the open position.
  • Clamping ring closures are also known, in which the movable elements of the closure are pivotable about axes which are perpendicular to the plane of the clamping ring, the elements being adapted to the circumferential curvature of the clamping ring so that they fit snugly on the outer surface of the clamping ring in the closed position of the container concerns (see German GM publications 72 10 719, 75 12 896 or 76 11 482).
  • the circumferential ends of the tension ring are neither in the open position nor in the closed position nor in any position in between.
  • there is also a profiled bridging piece in which both circumferential ends of the clamping ring are received and guided in each phase of the closure movement, the bridging piece being firmly connected to one circumferential end.
  • the bridging piece In the area of its other end, the bridging piece has on one side a tab projecting over the longitudinal edge, which is folded around the longitudinal edge of the movable peripheral end of the clamping ring to form a guide.
  • the pull tab is articulated, while the clamping lever is pivotally mounted at a distance from it on the clamping ring itself.
  • the tensioning lever thus lies directly above the tensioning ring at a circumferential distance from the bridging piece receiving the circumferential ends of the tensioning ring.
  • the peripheral ends of the clamping ring are guided and secured in the bridging piece.
  • this securing is not sufficient when the edge of such a container is subjected to high loads due to the action of external forces in order to rule out lateral deflection of the circumferential ends of the clamping ring or deformation of the bridging piece.
  • the semicircular profile of the clamping ring and bridging piece does not counter the possible high stresses of the clamping ring closure with a sufficiently high resistance to deformation.
  • the circumferential ends of the tension ring are not only continuously received in the profiled bridging piece in the closure according to the invention, but the movable circumferential end is always reliably guided over its entire engagement length on the bridging piece, so that lateral deflection of the circumferential ends of the tensioning ring does not occur during the actuation of the closure is to be feared.
  • an exact circular shape of the clamping ring is forcibly maintained by this design, which facilitates the actuation of the closure.
  • the dimensional stability of the closure area is increased considerably by the fact that in the closed position the clamping lever adapted to the profile of the clamping ring and bridging piece reliably overlaps the ends of the clamping ring and the bridging piece along its entire length on all free sides. This results in a double overlap and thus a double securing of the joint of the slotted clamping ring.
  • the clamping ring closure according to the invention is intended for use in containers made of sheet metal, such as buckets, hobbocks or the like.
  • a preferred embodiment of such a container is indicated in Figure 4.
  • the container 1 has a container fuselage 8, the edge region of which is formed into a spiral border 9 with winding regions lying under flank pressure and is thus stiffened.
  • the free edge of the border is indicated at 14.
  • the press-in cover 2 has a cover play 3 which is connected via a core wall 4 to an edge flange 5 which is curved outward in the shape of a circular arc.
  • the core wall can, as indicated, have a stacking shoulder 10 for stacking the lids.
  • the outer leg 6 is extended cylindrically downwards and its edge is rolled out at 7.
  • the curl 7 and the border 9 are arranged so that their lower edges lie in a common plane 12 running perpendicular to the container axis.
  • the border 9 has a much larger diameter than the curl 7 of the cover, preferably it is at least twice
  • the lid is pressed into the end of the fuselage to close the container, so that an originally O-ring-shaped seal 11 fills the space between the edge flange 5 and the flange 9, as shown in FIG.
  • the parts are held in the tightly compressed and sealed state by the clamping ring 15.
  • the clamping ring 15 preferably has an approximately trapezoidal cross-sectional profile. Its lower leg 16 runs parallel to the plane 12 and lies under flank pressure on the edge curl 7 and the border 9 of the lid and body. The inner edge 17 of the lower leg 16 lies firmly against the fuselage wall 8. The clamping ring 15 then nestles against the edge curl 7 and the arcuate curvature of the edge flange 5 with flank pressure with a corresponding curvature. The curved regions are connected to one another by the region 18 of the clamping ring. The upper leg 19 protrudes obliquely inwards and beyond the core wall 4 of the push-in cover.
  • the peripheral ends 15a, 15b of the clamping ring 15 are accommodated in the approximately trapezoidal, similar profile of the bridging piece 20 over almost the entire cross-sectional length.
  • the lower leg of the bridging piece ends approximately in the center line of the rolled edge parallel to the container axis, while the upper leg protrudes beyond the leg 19 of the clamping ring 15 and to form a guide 21 extending over the entire length of the bridging piece 20, which is folded inwards in the extended or in the dashed form in Fig. 4 can be executed.
  • the bridging piece 20 is in turn covered over its entire extent and over substantially the entire circumferential length with a trapezoidal profile of the tensioning lever 22 of the same type. This results in an extraordinarily high stability in the closure area.
  • FIGS. 1 to 3 show the closure in different phases and different views.
  • the bridging piece 20 and the clamping lever 22 are adapted to the circular curvature of the clamping ring 15. They also ensure that the circular shape of the clamping ring is maintained precisely in the interruption area of the clamping ring.
  • the bridging piece 20 is rigidly attached to the peripheral end 15a of the clamping ring 15, e.g. welded.
  • the bridging piece has an outer, circumferentially projecting tongue 29 with an outwardly projecting hook element 30, which in the closed position according to FIGS. 2 and 3 projects through a window 32 of the tensioning lever 22 and overlaps the tensioning lever in a locking manner.
  • the closure can only be opened if the hook-shaped end 30, which has a predetermined breaking point in the area 31 according to FIG. 1, is broken off. The closure thus acts as a guarantee closure.
  • the safety hook is designed so that all commercially available sealing devices can be used.
  • a rivet-shaped pivot pin 25 projects, on which the tensioning lever 22 is pivotally supported by means of tabs formed from the tensioning lever.
  • Flaps for a rivet-shaped pin 28 are formed out of the tensioning lever 22, on which one end of the e.g. is designed as a leaf spring clamping tongue 26 is anchored.
  • the other end of the clamping tongue or lug is attached to the circumference of the clamping ring 15 at 27, e.g. by spot welding.
