Definitions

  • the invention relates to a folding box with an inner lining, the box blank having a pre-punched tear-open removal opening area and the inner lining having a corresponding punched-out window opening area, and at least the removal opening area of the box blank and the window opening area of the inner lining being connected to one another by gluing, welding, heat sealing or the like.
  • Folding boxes of the type described above are subject to two demands acting in opposite directions. On the one hand, they should be as tight as possible (whereby a distinction is made between different degrees of density, such as free-flowing, dust-tight, grease-proof, water-vapor-tight, aroma-tight, liquid-tight and vacuum-tight), on the other hand they should ensure easy opening, targeted pouring out of the goods contained therein and, if possible, reclosure. To meet the latter requirement - they are provided with a pre-punched tear-open opening area in the box blank and a corresponding punched-out window opening area in the inner lining. Punching the inner lining can, however, in turn lead to leaks. Cardboard is usually used to cut the box. This is crucial for the tightness Lining material. A paper foil, plastic foil, metal foil, plastic coated paper foil, plastic coated metal foil or the like can be used for this.
  • the punching of the window opening areas on the inner lining film is of particular importance in the manufacture of the folding boxes to meet the tightness requirement. "Punching” practically means scoring the inner lining film without piercing it.
  • the window opening area should detach in a defined form from the rest of the inner lining when the removal opening area provided on the box blank, with which it is preferably connected by gluing, and remain attached to the removal opening area.
  • the punching of the window opening areas on the inner lining film is therefore carried out in a separate operation before the inner lining is combined with the box blanks. This is described, for example, in the applicant's patent 31 29 496.
  • the invention has for its object to improve folding boxes of the type described in such a way that the tightness is increased.
  • the inner lining is formed by a piece of film tube which is closed in the longitudinal direction of the tube.
  • folding boxes of the type considered here that is to say those with a removal opening area in the box cut and window opening area in the inner lining, have not hitherto been produced with a laterally closed piece of film tube, is that when the adjacent edge regions of the inner lining film are connected in the folded and erected box blank because of due to the lack of accessibility there were difficulties that could not be solved.
  • the use of a prefabricated film tube closed in the longitudinal direction was not considered, because it was always assumed that the inner lining to be punched immediately before being combined with the folded blanks had to be punched in one layer.
  • a further connection that partially or completely frames the window opening area can be provided.
  • This connection can be made by a corresponding glue pattern, which is applied to the box blank before the box blank and the inner lining are combined.
  • the fold line of the film tube piece forming the line of symmetry will generally run next to a fold line of the box blank forming an edge of the folding box.
  • the tube shape can be heated, for example sealing of two parallel edge areas of a single-layer film web placed against one another.
  • the fold line of the film tube piece forming the symmetry line mentioned above and the heat-sealed edge regions will run parallel to one another.
  • the invention further relates to a method for producing a folding box with adhesive connections between the box blank and the inner lining, in which the pre-punched box blanks are delivered one after the other and then provided with an adhesive application, in which the inner lining film is simultaneously delivered, then provided with the punchings forming the window opening areas and then cut into pieces of film, and then the pieces of film are brought together with the box cuts and glued.
  • a method for producing folding boxes in which the inner lining is tubular, but the adjoining edge regions of the single-layer inner lining film are not connected to one another, is described in DE-PS 31 29 496 by the applicant.
  • the invention is furthermore based on the object of designing the method described above in such a way that it is possible to produce the folding box according to the invention specified above.
  • the inner liner be supplied in the form of a flat film tube and essentially only one side of the tube to form the window opening areas is punched.
  • the invention relates to a device for performing the method described above.
  • a device with a punching roller is known, which is provided with a cutting edge profile corresponding to the window opening area and protruding from the roller surface, and at its ends with spacer rings (bearer rings), and with a counter roller with which the spacer rings are in contact, the inner liner to be punched being passed between the spacer rings through the gap formed by the punching roll and the counter roll.
  • the invention is furthermore based on the object of designing the device described above in such a way that the manufacturing method according to the invention for the folding boxes according to the invention can be carried out with it.
  • the height of the cutting edge profile protruding from the roller surface is approximately equal to the thickness of the single-layer tube wall and that the height of the spacer rings above the roller surface is approximately equal to the thickness of the flat double-layer film tube.
  • the box blank 1o shown in FIG. 1 is provided with a pre-punched removal opening area 100, which is similar to that described in the applicant's older German patent application P 33 01 999.1.
  • the dashed lines of the removal opening area 100 indicate perforation, while the solid lines are fold lines.
  • the box blank 10 shown in FIG. 1 is provided with glue patterns.
  • These glue patterns include the glue bars 1 0 5, which serve to connect the side walls of the box blank 1o and the piece of film tube to be described.
  • a glue pattern lo2 is provided within the removal opening area 1oo, which is used to connect the removal opening area 1oo and the window opening area of the film tube piece to be described.
  • an incomplete glue frame 1 0 1 is provided which surrounds the removal opening area 1oo.
  • glued patterns 103 and 104 are provided on a fold line lo9 of the box blank 1 0 .
  • FIG. 3 shows that a folded piece of film tube 9, which is shown in FIG. 4, is placed on part of the box blank 10.
  • the underside of the tubular film piece 9 is provided with a punched-out window opening area 106.
  • the window opening area 106 is connected to the removal opening area 1oo by the glue pattern 102 (see FIG. 2).
  • Two corners of the window opening portion 106 are provided over the removal opening - 1oo area laterally beyond, but are not glued to the carton blank 1o. Therefore come loose these corners when tearing open the removal opening portion 1 00 and easily be taken away by the bonded window opening portion lo6.
  • FIG. 5 shows the finished but opened folding box.
  • the purpose of the protruding corners of the window opening area 106 is that when the removal opening area 1oo is closed again they get caught behind the opening edge and fulfill a locking function.
  • Fig. 3 it can also be seen that the glue pattern lo2 lies within the window opening area 106 and the removal opening area 1 00 and thus connects the two. It can also be seen that the glue pattern 1 0 1 largely frames the window opening area 106. The frame is only interrupted at the top because otherwise the part of the inner lining located there would be entrained when opening the removal opening area 100.
  • the frame-shaped glue pattern 1 0 1 is a safeguard against injury to the punched film tube wall and, when the folding box is open and reclosed, prevents the goods packed in the folding box from serving through the reclosed opening gap along the punching line of the window opening area 106 between the film tube 9 and the folding box carton can trickle or flow.
  • FIG. 6 shows a first part of a device for carrying out a method for producing the folding box shown in FIG. 5. This is the feed cutting and gluing system, without a punching unit.
  • a roller transport device pushes an already finished, but flat-lying film tube 1 made of paper over a deflection roller 2 between a brake shoe 4 and a counter bearing 4a, further over a deflection roller 3 onto a vacuum roller 5, which is in direct drive connection with a knife roller 6.
  • the drive of the vacuum roller 5 and the knife roller 6 is not shown.
  • a loose pressure roller 7 loaded with spring force and resting on the vacuum roller 5 ensures hose contact with the vacuum roller 5.
  • a feed of a certain length takes place per revolution of the vacuum roller 5 or the cutter roller 6.
  • the feed length is equal to the section length.
  • the brake shoe 4 is pressed by means of spring force 8 against the counter bearing 4a, so that the film tube feed stops briefly. During the stop, a piece of film tube 9 is cut off, which is held by the vacuum roller 5 and placed and pressed onto a box blank 1o which has already been provided with a glue pattern. The transport of the box blank 1o is not shown.
  • Figure 7 shows a plan view of the feed unit and the drive for the brake shoe control.
  • the gears 11 and 13 are change gears and must be changed depending on the number of sections per roller revolution.
  • the punching of the window opening areas lo6 requires a driven punching roll, the circumference of which must correspond to the length of the film tube section.
  • a punching roller 16 with spacer rings 17 (so-called bearer rings) is used. The distance between the spacer rings 17 is greater than the maximum width of the flat film tube.
  • a pressure screw device 18 causes the spacer rings 17 to be constantly pressed onto a counter-roller 19 heard, as a result of which the necessary punching pressure for the punching roller 16 is generated.
  • the punching roll 16 is provided with a punching cutting profile 20 which projects up to a height h into the gap 111 formed between the punching roll 16 and the counter roll 19.
  • This height h is only half as high as the diameter A of the gap 111.
  • the latter is chosen such that it corresponds approximately to the thickness of a flat film tube 1.
  • the counter roll is loosely mounted on the existing shaft 14. Because of the translation of the change gears 11 and 13, the shaft 14 runs at one revolution per piece of film tube 9. The shaft 14 is also used as a drive for the punching roller 16 (see FIGS. 8 and 9).
  • a gearwheel 21 is fastened on the shaft 14, which sets a shaft 23 in rotation via a gearwheel 22, from which the drive to the punching roller 16 takes place via a further gearwheel 24 and a gearwheel 25 (see FIG. 11).
  • a pair of slides 26 is also supported on the shaft 14, which carries two slider blocks 27, which serve to receive the punching roller 16 (FIG.
  • the punching roller 16 can be pushed regardless of its respective diameter in the two scenes and fixed with the clamping devices 18.
  • FIG. 8 shows how the film tube 1 has to run through the punching device. It runs, pushed by a transport roller (not shown), over a deflection roller 29 between the spacer rings 17 of the punching cylinder 16, over the counter-roller 19 onto the deflection rollers 2 and 3 to the vacuum roller 5, where it is cut into film tube pieces 9 by means of the knives 6a (see FIG. 6) .
  • the window opening areas lo6 are punched on the counter roller 19.
  • the film tube 1, which is flat at the time of the punching and has two layers, must not be punched through.
  • the lower hose wall may be scratched at most. How this is achieved has been described in connection with FIG. 12.
