Definitions

  • the invention relates to a device for gassing and closing packaging containers according to the preamble of the main claim.
  • a device of this type which has become known, for example, from DE-OS 2421531
  • the gas supply lines protrude between the containers and the film web that tapers towards the container at a flat angle.
  • a uniform gas distribution is achieved when the contents in the containers assume a flat mirror.
  • a device is desirable with which containers can also be closed in a protective gas atmosphere in which, for example, pasty or paste-like filler portions, due to the filler, are filled in the form of a heap in the container, the upper part of the heap projecting beyond the container opening.
  • the device according to the invention with the characterizing features of the main claim has the advantage that the accumulation of the fillings portions, without coming into contact with a foreign body, is distributed in the container by the supported film web with simultaneous flushing with protective gas.
  • the containers can have the shape of a bowl and are connected in a chain-like manner, or it can be used for individual containers such as cups, bowls and the like. Like., Use a transport device with plates, which forms the lower boundary surface for the wedge-shaped fumigation space together with the containers.
  • a gas flow occurs essentially in the form of a serpentine line, so that a clean flushing of the head space of the containers and the accumulation of the filling material occurs , whereby a particularly low gas consumption is achieved.
  • the container-forming, filling and closing device has, in succession, a shaping device 10 in which bowl-shaped containers 2 are formed at equal intervals in a packaging material strip 1, a filling device 11, a gassing device 12 and a closing device 13 in which a film web 3 with the Edges 5 of the contiguous containers 2 are sealed, which are separated by a cutting device 14 after closing.
  • Means 10-13 for forming, filling, gassing and closing the containers 2 are arranged in a chamber 15 in which an aseptic atmosphere is maintained by initially sterilizing and supplying a sterile gas with positive pressure in order to aseptically pack perishable goods, such as e.g. B.
  • a device 12 for supplying an inert gas and maintaining a protective gas atmosphere is arranged in the device between the filling and closing devices 11, 13.
  • the filled containers 2 which are conveyed by a conveyor device (not shown), are carried by a support track 20 and their laterally projecting edges 5 are guided by strips 21.
  • the second deflecting roller 23 is arranged at a distance above the containers 2 such that its lower surface line is at a distance from the top of the containers 2 or their edges 5 which is somewhat larger than the accumulation of the filler portions 4 inserted in the containers 2 In this way, the film web 3 is guided to the closing device 13 in a plane inclined at an acute angle to the plane of the containers 2. Between this deflection roller 23 and the closing device 13, a plate 24 is arranged in a stationary manner, the underside of which lies in the above-described, inclined plane and forms a supporting slideway for the film web 3.
  • a plate 25 adjoins the plate 24, which extends into the U-shaped upper welding tool 26 of the closing device and whose underside runs at a small distance and parallel to the top of the container 2.
  • the plate 24, the strips 21 and the support track 20 are firmly connected to two side plates 28.
  • two pipes 30, 31 tapering in height protrude into the wedge-shaped space delimited by them are connected to a gas distributor 32.
  • the gas distributor 32 is supplied with adjustable gas from a supply of inert gas through a sterile filter 33, a throttle valve 34 and a flow meter 37.
  • the two pipes 30, 31 extend longitudinally in register with the lateral edges 5 of the containers 2 and the film web 3 in the region of the gassing device 12. They have gas outlet openings 35 on the sides facing one another with a flow direction running transversely to the conveying direction of the containers 2.
  • the gas outlet openings 35 are arranged at a distance of two container lengths on a tube 30, 31, namely on the mutually facing sides of the two tubes mutually offset by one container length, so that an essentially serpentine gas flow (arrows) between the film web 3 and the containers 2 at the top and bottom bounded wedge-shaped space from the top, with a combined cross and counter flow in the gassing device 12 is present. With this flow, which also flushes the spaces between the filler portions 4 well, very low oxygen values are achieved in the closed containers 2 with low gas consumption.
  • the film web 3 resting on the edges of the containers 2 at the end of the gassing device 12 is still held down by the shoulder 25 of the plate 24 and sealed by the pressed tools 26, 27 of the closing device 13 by means of a U-shaped sealing seam 6 with the respectively supplied container 2.
  • the transverse seam part forms the rear closure seam of the leading and the front closure seam of the subsequent container 2.
  • contiguous containers 2 are filled, gassed and sealed in a single row.
  • 4 shows, in simplified form, an exemplary embodiment in which two-row, contiguous containers 2 are treated.
  • a gas supply pipe 38 is arranged above the free side edges of a row of containers.
  • Each gas supply pipe 38 has gas outlet openings 35 at a distance of two container lengths, which are arranged offset by one container length.
  • This embodiment according to FIG. 4 is particularly useful for small containers.
  • the embodiment according to FIG. 5 is suitable for treating containers 2 fed in four rows.
  • gas supply pipes 39 are also arranged above the connected side edges of the containers.
  • the arrangement of the gas outlet openings 35 is as described in the exemplary embodiment according to FIGS. 1 to 3.
