Definitions

  • the invention relates to a toggle-operated clamping ring closure for containers made of sheet metal, such as a bucket, hobbock or the like, with a press-in cover, with the features of the preamble of claim 1.
  • a toggle-operated clamping ring closure with the features of the preamble of claim 1 is known from DE-U-76 11 482.
  • the tensioning lever is pivotally mounted on one end of the tensioning ring, while the pull tab connected to the tensioning lever is pivotably articulated on the end of the bridging piece facing the tensioning lever.
  • the other end of the bridging piece is firmly connected to the end of the clamping ring facing away from the clamping lever.
  • the bridging piece is seen in plan view according to the curvature of the clamping ring and curved in cross-section semicircular and open to the center of the clamping ring.
  • the curvature of the bridging piece corresponds to the cross-sectional profile of the clamping ring.
  • the bridging piece can thus fit snugly against the outer surface of the free end of the tension ring and forms a guide for this end when the tension ring end slides slidably in the bridging piece when the closure is tensioned.
  • the bridging piece has at its end facing the tensioning lever on one side a projecting over the longitudinal edge, integrally formed tab, which can be folded around the one longitudinal edge of the end of the tensioning ring displaceable in the bridging piece to secure this end in the bridging piece. In the closed position, 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 semicircular profile of the clamping ring on the one hand and the bridging piece on the other hand do not guarantee a sufficiently high one Resistance to deformation against the possible high stresses of the clamping ring closure.
  • the two circumferential ends of the clamping ring are continuously received in the profiled bridging piece, as in the known case.
  • the free, movable peripheral end of the clamping ring is held and reliably guided over its entire length of engagement on the bridging piece in every phase of the closing or opening process.
  • a lateral deflection of the circumferential end of the clamping ring is therefore not to be feared under any circumstances when the closure is actuated.
  • the dimensional stability of the closure area is increased significantly by the fact that in the closed position of the tensioning lever adapted to the profile of the tensioning ring and the bridging piece, the ends of the tensioning ring and the bridging piece also reliably overlap the entire length of all free sides. This ensures a double overlap and 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, 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 presses 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 again 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 clamping tab is attached to the circumference of the clamping ring 15 at 27, e.g. by spot welding.
