Definitions

  • the invention relates to a method for manufacturing a container with a jacket made of cardboard or the like. is wound and is preferably closed with a metal lid that can be torn open along a predetermined breaking line, as well as a device and a container manufactured with it.
  • Such a metal cover equipped with an additional edge is relatively expensive and can only protect against contact with the upper edge of the break line. However, it is precisely this upper edge that is much less dangerous than the lower, still unprotected edge due to the scratch line on the top of the lid.
  • Such a bead would be extremely difficult to manufacture in a container wrapped in cardboard. In addition, such a container would then no longer have any compressive strength, so that it would be completely unusable.
  • the invention has for its object to provide a method of the type mentioned, and a container produced thereafter, with which there is no risk of injury when using a tearable sheet metal cover, but which does not lose its strength.
  • This object is achieved in that the upper edge of the cardboard casing is rolled inwards in one or more steps and then pressed to form a double flanging, the flanging standing vertically upwards, forming the upper end of the container casing and being connected to the lid can, while the second flange protrudes radially inwards.
  • This flanging projecting radially inwards effectively prevents accidental contact with the tear-open edge of a possibly existing sheet metal cover.
  • An advantageous embodiment of the method according to the invention also lies in the fact that the flare standing vertically upwards is pressed flat in the horizontal direction.
  • the flanging projecting inwards can also be pressed flat in the vertical direction.
  • the stability of the container can be further improved by these pressings.
  • the attachment of a lid can be made easier.
  • a device for carrying out the method is characterized in that a turntable is provided with a plurality of holding mandrels, each of which is assigned to a processing station, the first of which for. Wrapping the container jacket from a flat cardboard blank or the like.
  • a sealing device preferably an ultrasound sealing device, for producing the longitudinal seam of the container, and that in at least one further A device for flanging a mouth roll is provided in the station, while a pressing device is arranged in a subsequent station, which presses the mouth roll into a double flare and at the same time at least partially presses it flat, and that a cover placement device is also provided, which is provided with a cover magazine and in which the sheet metal cover is pressed with the flare of the double flare standing vertically upwards.
  • a sealing device preferably an ultrasound sealing device
  • the method for producing the aforementioned container can be carried out in a simple and extremely efficient manner.
  • An inventive container with a jacket made of cardboard or the like. is wound and preferably closed with a metal lid that can be torn open along a predetermined breaking line, characterized in that the container jacket is folded inwards at its upper end, is provided with a flanged edge at this upper end, and that the free one lying on the inside of the container End of the container shell is formed into a further beading which projects inwards and lies below the upper edge.
  • a metal lid of the type mentioned provides reliable protection against contact with the tear-open edge and has excellent stability.
  • Fig. 1, 1 denotes a container
  • the container jacket 2 is wound from a substantially rectangular cardboard blank and closed with a longitudinal seam 3.
  • the container jacket 2 is provided with a double flange 4, one flange 5 of which is vertically upward and the other flange 6 projects into the container interior.
  • a sheet metal cover 7 with its flanged edge 8 is placed on top of the flare 5 standing vertically upwards and pressed with it.
  • the inward flare 6 lies directly on the underside of the metal cover 7.
  • an edge 9 remains which stands inside the container, but the flange 6 projects beyond this edge 9 to such an extent that its lower edge 10 cannot be touched. 2 and 3 the career of the double flanging is shown.
  • a mouth roll 11 is flanged, from which the double flanging shown in FIG. 3 is formed in a further operation. This double flanging is then radially and axially pressed flat in further operations, not shown.
  • FIG. 4 shows an embodiment of a device with which the container 1 can be produced.
  • Eight identical mandrels 20 are arranged on a turntable, not shown, which are each assigned to a processing station 21 to 28.
  • a magazine 29 for cardboard blanks is provided, which is fed to the holding mandrel 20 and wound there to form a container wall 2.
  • a sealing device 30 is arranged, with which the longitudinal seam is closed with the aid of ultrasound.
  • a mouth roll is crimped inwards in two stages at the upper end of the container, as shown in FIG. 2 in the finished state - i.e. after station 24.
  • the station 25 is provided with a press tool, not shown, with which the mouth roll shown in FIG. 2 is formed into a double flange 4. At the same time, the flare 5 standing vertically upwards is pressed flat in the horizontal direction. In station 26, the flange 6 standing inside the container is then pressed flat in the vertical direction.
  • the station 27 is assigned a magazine 31 in which sheet metal covers 7 are stacked, which are placed in this station on the upper flange 5 in a manner not shown in detail and pressed together with the latter.
  • a lifting device 32 is arranged in the station 28, which lifts the container 1 from the holding mandrel 20 and transports it away.
