Definitions

• the invention relates to a method and a device for the production of packaging sleeves for a carton / plastic composite packaging provided with an opening aid, in particular a beverage packaging, and a packaging jacket produced therewith and its use.
• Beverage packs made of cardboard / plastic composite material have long been known and are available on the market in a wide variety of shapes and forms.
• the beverage packs often have an opening aid which makes it possible to open the pack at a predetermined point for removing the product contained therein and, if necessary, to close it again.
• Such beverage packs are produced either in the so-called tube forming process from an endless composite material web or from individual pre-cut blanks. For example, it is known from EP 0 558 946 B1 to punch a recess in the packaging material web or a blank in the region of the subsequent pouring opening, which is then sealed again with a tear-off label. Alternatively or additionally, this opening can also be provided with a reclosable pouring element.
• the material used for such packs consists of a raw cardboard, the inner and outer surface of which are coated with a thin plastic layer, usually PE film. In this way, such a pack is adequately protected against external influences such as moisture or dust on the one hand and on the other hand the product it contains is hygienically and cleanly separated from the raw cardboard material.
• the surface can be printed permanently. In the area of the openings, however, the composite material is punched through, so that the product can come into contact with the raw cardboard during pouring. This can lead to contamination of the product on the one hand, but also to a softening of the cardboard by the absorbed liquid.
• the invention is therefore based on the object of providing a method and a device for producing packing sleeves for cardboard / plastic composite packs provided with an opening aid, in which the aforementioned problem is reliably avoided, so that no contact even after the packs have been opened for the first time can take place between raw cardboard material and product in the area of the pouring opening.
• the coating is preferably carried out with a polyethylene (PE) layer in the extrusion process.
• PE polyethylene
• the raw cardboard is coated in two successive steps.
• the composite material can still be perforated in or immediately behind the coating system in the region of the over-coated openings in order to produce the pouring openings.
• the composite material is preferably printed on its outside after coating. Printing on the package at this point in the process sequence is particularly expedient since no crease or fold lines have yet been applied.
• the material composite web can be printed at high speed using rotary printing machines. Alternatively, however, it is also possible to print the outside of the cardboard with the plastic layer before overcoating.
• the packaging sleeves are folded flat and finally packaged.
• the flat-folded and finally packaged packaging sleeves are then transported to the appropriate bottling plants, where they are first provided with a packaging base on a filling machine and then filled and closed.
• the object is achieved in a device with the features of the preamble of claim 9 in that a further punching unit for punching out pouring openings is arranged in the region of the over-coated openings.
• This further punching unit can be arranged behind the creasing and punching unit.
• the creasing and punching unit is designed as a rotating punch. With such a device, transverse or longitudinal creasing or folding lines can be produced simultaneously.
• a packing jacket produced by the method according to the invention or with the device according to the invention is characterized in that the raw cardboard material around the punch opening is completely coated with plastic.
• use of the aforementioned packaging jacket provides that not only the inside of the package, but also the pouring opening, are sterilized before the filling and closure of the finished package, and that a sterile tear-off label and / or a reclosable pouring element is placed on the pouring opening is / will be applied.
• a raw cardboard web 1 drummed on a roll is first fed to a punching unit, in which openings 0 are punched out in the area of the later pouring openings of the beverage cartons to be produced.
• 2A shows the raw cardboard material web 1 as it passes through the punching unit, of which only two punching dies 2A and 2B are shown, which ensure that the openings O are made regularly. At this point arise as
• the raw cardboard material web 1 is then fed to a coating system.
• a first unit the first surface of the web 1 is coated with a plastic film.
• a plastic film Such a unit can also be used for the coextrusion of a further foil, for example aluminum foil.
• 1B shows schematically how the openings 0 produced are over-coated.
• a liquid plastic film 5 is indicated here, which is applied from a first extruder unit 4 to a surface of the moving web 1.
• the second surface is treated accordingly by a second extruder unit.
• the other surface is coated with a plastic film 6, which is only shown from below for the sake of clarity.
• the cardboard / plastic composite material web 1 ' which is now coated on both sides, is then fed to a printing unit 7, where a print is applied in accordance with the desired print image of the subsequent pack, as is shown schematically in FIG. IC.
• Printing on the coated outside of the composite material is preferred, but it is also possible to print on the raw cardboard before coating.
• a creasing and punching unit 8 in which the creasing and folding lines necessary for the pack formation are produced.
• FIG. 1D shows schematically how the web 1 'is provided with the crease and fold lines, which are not necessary for the formation of the pack, by means of a rotary punch.
• Composite material web 1 'individual blanks 11 are produced.
• FIG. IG schematically shows that the individual blanks 11 are sealed at their longitudinal seam L and stacked flat in a carton 12.
• the packaging sleeves M thus produced and finally packaged are then transported to the actual bottling plants.
• FIG. 2A a cross section of an over-coated opening O in the cardboard material 1 is shown again in FIG. 2A, which is coated on its upper and lower surface with a plastic layer 5 and 6, respectively. It can be clearly seen that the two plastic layers 5 and 6 form a single plastic film in the area of the openings 0. The cardboard edges of the openings O are completely sealed with plastic material.
• FIG. 2B now shows a cross section of a pouring opening P punched in an over-coated opening O.
• the fact that the pouring opening P is smaller than the punch opening 0 means that the product passing through the pouring opening is achieved
• FIGS. 3A to 3F schematically show how finished beverage packs are produced from the packaging sleeves M.
• the bottom is first shaped and the package C is closed on the bottom.
• 3B schematically shows the sterilization process of the package C from the inside, the region of the pouring opening P also being sterilized from the outside.
• FIG. 3C schematically shows the supply of a sterile tear-off label 13 which, as shown in FIG. 3D, is cut to length after being sealed onto the package C. In this way, the pouring opening P is reliably closed.
• the pouring openings P can, in addition to the tear-off label 13, also - or alternatively - be provided with a reclosable pouring element.
• FIG. 3E the container sterilized inside being filled with the product J to be packaged.
• the complete manufacture of the ready-to-sell beverage package is completed, as indicated in FIG. 3F.
