Definitions

  • the present invention relates to a process for the manufacture of an easy open device for "Flow Pack” or similar packages with longitudinal seams and transversal closures, an opening device obtained through said process, and the package using it.
  • Portfolio-type packages are produced by the movement in the machine direction of the already-printed packaging film, said printing generally being readable in the direction perpendicular to the film's movement.
  • the product to be packaged arrives at the film perpendicularly to its movement, supported by disks on both ends.
  • a detaching or easy open strip is incorporated longitudinally into said film by an applicator head.
  • the detaching strip comes on a spool. While continuously unwinding, it is fixed with adhesive to the internal face of the packaging film in an area near one end of the product to be packaged. Said strip is not longer than the width of the package, generally not exceeding 15 cm, and one of its ends is exposed by lateral incisions to allow for manual detachment so the packaged product can be accessed.
  • This type of package uses heat activated adhesive to seal the ends, because of which the product to be consumed can also be damaged, due to the pressure of the disks and the temperature applied, as in the case of packets of crackers, in which the first and last are generally damaged.
  • the product In horizontal packaging, the product is positioned on the printed film which will make up the package in [a] direction parallel to the readable printing, because of which it must enter parallel to the machine direction, which means perpendicular with respect to the aforementioned packages that are produced longitudinally (or "portfolio").
  • the film closes over itself on one face of the package, producing a longitudinal fold or seam which is heat sealed. The same occurs on the ends. Due to the manufacturing characteristics of this type of package, the application of a detaching strip which is continuous and in the machine direction, as in the case of longitudinally-manufactured packages, involves several difficulties, such as:
  • the purpose of using the present invention is to provide a process for inserting a detaching or "easy open” strip in Flow Pack or similar packages with longitudinal seams and transversal closures, manufactured horizontally or vertically.
  • Another purpose is that said detaching strip be easy to detach.
  • Still another purpose is that the opening procedure not endanger the integrity of the package.
  • Yet another purpose is that the process for including a detaching strip not increase costs.
  • a further purpose is to provide an easy closure for packages with longitudinal seams and transversal closures.
  • FIG. 1 of the drawings there is shown a longitudinal wrapping or portfolio packaging machines.
  • Packaging film 1 on which the product to be packaged is deposited 2 is moved, with printed face 3 down and readable perpendicularly to the machine direction.
  • the product to be packaged enters through one side on a conveyor belt 4 perpendicularly to the machine direction, as indicated by the arrows.
  • This process incorporates a detachable strip 5, which is attached to the internal (unprinted) face 6 of the packaging film 1.
  • This detachable strip is continuously unwinding from the spool 8 so that, after the final cut, it will surround the entire perimeter of the package 7. Its final length is, in the majority of cases, not greater than 15 cm. This, of course, depends on the product to be packaged.
  • Figure 2 shows how horizontal Flow Pack packages are produced.
  • the packaging film 1 is moved, with printed face 3 up and generally readable, parallel to the machine direction, as indicated by the arrows.
  • the product 2 to be packaged is incorporated in the machine direction.
  • the packaging film 1 is folded, wrapping the product 2, and a longitudinal seam 12 is generated.
  • This seam is preferably located in the centre of the package, which is heat- or cold-sealed.
  • the same occurs with the ends of the package 9, which are pressed, heat- or cold-sealed, and cut. In this way the process keeps mechanical elements from coming into contact with the product 2 to be consumed and jeopardizing its integrity.
  • Figure 2 shows a spool 8 with a rolled plastic siliconed carrier or liner 10 that has detaching strips 5 not longer than the width of the packaging film 1, which is the object of the present invention.
  • Said strip 5 has adhesive on its printed face; this process is called “occluded printing.”
  • the ink is occluded because of the requirement to not expose the printed face to the package contents 7.
  • the siliconed carrier 10 is punched and, using an applicator head (not shown in the figure), the detaching strips 5 are applied to the internal face of the packaging film 1 continuously, accurately aligned.
  • Said strips 5 must be thick and rigid enough so that, once the cut is initiated, the subsequent release of the material accompanies their detachment.
  • these detaching strips 5 are placed along the width of the siliconed carrier 10 that supports them. This means that they will be deposited transversally with respect to the machine direction and perpendicular to the readable printing on the packaging film 1.
  • the release area 17 figures 5 and 6 can be generated on just one face of the package 7 or on all of them (with total detachment of the portion of the package above said strip).
  • the fact that the release area 17 figures 5 and 6 is not the total perimeter of the package 7 makes it possible to use an easy open/close element 11 Figures 3 and 5 that enables said package 7 to be closed for subsequent use, thus preserving the product to be consumed.
  • This easy open/close element 11 Figures 3 and 5 can either be affixed to one face of said package 7 or inside said package 7 as a self-sticking label.
  • Said detachable strip 5 can be positioned on any part of the package 7. Everything will depend on the type of product to be consumed. In the case of disposable tissues, it could be inserted in the middle of the package 7, but in the case of crackers, a position near one of the ends 9 would be suitable. Application is made with a standard aligning applicator head known in the art which, through the optical reading of a reference element on the packaging film 1 (not provided in the figure), indicates where said detachable strip 5 should be affixed.
  • Optical alignment is much more accurate than mechanical devices in relation to the aforementioned problem of displacement, with which the associated problems regarding release are also solved.
  • the place where said strip 5 is to be affixed is previously input manually in the production line control logic (PLC), which in turn transmits the information entered to the optical reader, which activates the applicator head when said strip 5 must be affixed to the packaging film 1.
  • PLC production line control logic
  • Figure 3 shows a packaging machine for vertical Flow Pack packages, also called sacks 7. Gravity plays an important role in this process.
  • the film 1 moves vertically (see arrow), producing first a package 7 with a longitudinal seam 12 generated by means of longitudinal clamps 22, a sealed lower end 13 generated by means of transversal clamps 23, and an upper end 14 originally opened by means of a shaping shoulder 21. Through it enters the product to be packaged, which is gravimetrically or volumetrically measured out through the hopper 21.
  • the subsequent heat sealing of said upper end 14 by action of the transversal clamps 23 shapes the lower end 13 of the next sack, and so on. This process is not continuous, since it is necessary to wait for the package 7 to be filled in order to move on to the next.
  • the purpose of the present invention is to participate in the packaging process through the previously-described spool 8, which has a siliconed carrier or plastic liner 10 that supports the detaching strips 5, which, by means of an applicator head (not shown in the figure), are affixed transversally to the packaging sheet 1 and aligned with a through cut 18 generated by the first cutting machine 24. Then the easy open/close element 11 is attached, also aligned and on the area of said cut 18, by means of another applicator head (also not shown).
  • Figures 4 A to C show an example of [the] opening sequence for the Flow Pack packages from the longitudinal seam.
  • the detaching strip 5 be located on the face that is not affected by the seam 12 or it could be required that the desired length of the strip not touch the seam; this example will be described in the next Figure.
  • an easy open/close element 11 could be used on one of its faces 19 with the part of the surface that is attached blocking said through cut area Figure 5B reference 18) and one end of the detaching strip (5).
  • the other part of the surface of said easy open/close element 11 does not contain adhesive, so it can be easily grasped by the end user Figure 5 A and can begin the release area 17.
  • said release area 17 Figure 5B When said release area 17 Figure 5B is begun, it extends to one side of the package 7 Figure 5C, in turn generating an upper flap 20.
  • said upper flap 20 folds over itself 5E and over the release area 17 and then adheres to one of the faces of the package 7 (Figure 5F) using said easy open/close element 11 previously detached from the detaching strip 5.
  • the affixing of the detaching strips 5 to the internal face of the film 3 of the package 7 may be accomplished on line in real time via a spool 8 that is unrolled as the packages 7 are constructed, or off line, in which case the packaging film 1 is ready to be incorporated after the packaging process with the strips 5 included. This latter case involves unrolling the entire spool 8, affixing the strips 5 at intervals controlled by optical and/or mechanical reading, and ultimately rewinding said spool 8.
