Definitions

  • DE-OS 2744506 has already disclosed a method in which for Containers and for the lid a multilayer tape is provided, which is composed of a packaging material tape and a protective tape covering the inside thereof, and in which the two sides of the two layers which are in contact with one another are kept germ-free.
  • the two layers are peeled from one another in a sterile room in which cup-like containers are formed and filled.
  • One packaging material band is then formed into containers and the cover band is sealed onto the containers after filling.
  • the peeled backing tapes are rewound and subjected to a recycling process.
  • the protective tape be used as a cover film for the containers.
  • the protective tape must be put together with the packaging tape under sterile conditions.
  • the binding should be set so that the protective tape can be easily peeled off the packaging tape.
  • it should be easy to seal with the packaging tape. This gives restrictions on the seal seam strength that can be achieved.
  • the protective tape must not be too thin to ensure that the peeling functions. The material requirement is therefore relatively high. Since the individual layers have to be put together in a sterile state, preferably immediately after their production, printing on the protective tape is hardly possible, so that it is hardly an option as a cover film. Furthermore, the production of the tapes is very expensive, since this requires a very special starting material which is formed into a tape under controlled, aseptic conditions.
  • the packer is deprived of some points for ensuring the sterility of the packaged products. Infection of the tapes can occur during the manufacture, printing, cutting, transportation and storage of the tapes. In particular, in these operations, accidental delamination can occur on the side cut edges, which leads to a local infection. For this reason, in practice, the protective tape to be peeled is slit at a distance of about 1 cm from the edge, so that the endangered outer zone is not fed into the processing. This procedure results in additional waste.
  • a method for producing two-part sterile packs according to the preamble of claim 1 in which a packaging tube is provided with a sterile inside, which is divided into two bands at the two kink edges when it enters the sterile room in which one bowl is shaped and filled, and finally the other band is sealed onto the bowl band.
  • the thickness of the tube wall can be very thin, since the sterility inside the tube can be easily maintained.
  • the bowl band can be underlaid with a separate deformable band, which is then deformed together with the one band of the hose.
  • this method has the advantage that it can be assumed that the standard material is much cheaper, that the sterility inside the tube is much easier to achieve than with a flat material, and that sterility during storage and transport is less likely to be impaired because the hose is closed on the side. Furthermore, the padding of the bowl band with an additional deformable band is further advantageous if, in the case of a possible print, it is not the bowl band itself but the additional band which is imprinted.
  • a disadvantage of the packaging manufacturing method according to DE-OS 3019503 is that after the tube has been divided into two bands, the band intended for the closure has to be transported over a longer distance, which bridges the stations for forming and filling the cups, for this purpose Care should be taken to ensure that the sterile inside is not infected from the non-sterile outside.
  • the method according to the invention for producing sterile packs with the characterizing features of claim 1 has the advantage that each of the two tubes only has to be slit open immediately before it is further processed, so that transportation difficulties are avoided. Furthermore, hoses can be used for the cup band and for the closure band. different sealing or welding properties are used, so that in this way the force for pulling off the sealing tape from the edge of a cup can be influenced to open the packs.
  • a heating station 12, a molding station 13 and a filling station 14 are arranged side by side in a sterile room 11 surrounded by a housing 10 with a sterile atmosphere. Outside the housing 10 there is a sealing station 15 and a punching station 16 in addition to the filling station 14.
  • the housing 10, which is open at the bottom, has a narrow gap 17, 18 in each of its two end walls for the insertion of a thin, flat-lying hose 21, 22 housing 10, which is open at the bottom, is closed by a band 23 which is pulled off a supply roll 24. Furthermore, a band 27 is introduced from a supply roll 28 into the sterile room 11 via deflection rolls 25, 26.
  • the band 23 and the hose 21 consist of a deformable packaging material, preferably of a thermoformable plastic.
  • the band 27 and the hose 22 consist of a well sealable packaging material.
  • the first tube 21, from which and the band 23 containers are formed, is guided from above via a deflection roller 30 against the center of the band 23, a kink edge 31 running through the gap 17 into the sterile space 11 of the housing 10.
  • the tube 21 is slit lengthways a little above the level of the band 23 on its kink edge 31 located in the sterile space 11 by a slitting knife 32. Its two layers connected at the other kink edge are unfolded by two angled tubes 33, 34 to form a flat band 35 which comes to rest on the band 23.
  • Two guide rod 36, 37 guide the superimposed layers of the hose 21 below the slitting knife 32.
  • sterile air or a sterile gas is blown between the still lying layers through the two tubes 33 and 34 and through a nozzle arranged below the slitting knife 32 emerges and generates a flow to the outside due to the slight overpressure.
  • the sterile air introduced also keeps the sterile room 11 under a slight overpressure, so that sterile air can flow out through the gaps 17, 18 and at the slits that occur between the band 23 and the underside of the housing 10 and thus an infection of the sterile room 11 is avoided.
  • the two belts 23 and 35 lying one on top of the other are moved through the individual processing stations 12 to 16 by a conveyor device, not shown, with the sterile inside of the band 35 formed from the hose 21 pointing upwards.
  • the heating station 12 they are heated to a temperature suitable for thermoforming, and they are also laminated together when using heat contact plates.
  • cups 40 are drawn into the two-layer belt 23, 35.
  • the band 35 comes to lie in the interior of the bowl and, with its sterile surface, forms the inside of a bowl 40.
  • the bowls are filled with portions of a sterile product.
  • a sealing tape 41 is placed on the double band 23, 35 containing the wells 40 and this is sealed in the sealing station 15 with the edge of the wells 40.
  • the connected, closed cups 40 are separated into individual packs in the punching station 16.
  • the closure band 41 like the bowl band 23, 35, has two layers. Its two layers consist of the band 27 and a band placed thereon, which is formed by slitting the hose 22 fed through the gap 18 at the right end of the housing 10.
  • the tube 22 is inserted into the housing 10 in the same way as the first tube 17, slotted there and its wall unfolded flat on the band 27, its sterile inner surface facing away from the band 27 and pointing upwards.
  • the band 27 imparting strength and / or tightness to the closure band 41 can consist of aluminum, paper, cardboard, plastic or also a combination of such materials and can carry a heat-sealable coating which enables the band 22 to be glued to the hose.
  • the band 23 and the band 35 formed from the hose 21 can also consist of a cold-formable material, so that the containers can be shaped by deep drawing or deepening without the heating device 12.
  • the containers can be dispensed with a certain rigidity, they can also be produced only from the hoses 21 and 22, the straps 23 and 27 being omitted.
  • the tubes 21 and 22 can also be slit and unfolded into a band by making a separating cut in the middle of a layer between the two kink edges and spreading out the two halves of the upper wall lying on the side outwards. This procedure is preferably carried out after the hose 21 has been placed centrally on the belt 23.
