Definitions

  • the invention relates to a pouch-type packaging for pourable contents, having a front wall and rear wall made from at least one flexible packaging film, such that the front wall and the rear wall are joined together via a sealing seam at a sealing edge and featuring a manual aid-to-opening for the purpose of opening the pouch and removing the contents.
  • the pouches are normally made up of film-type laminates and feature on the outside a printed, possibly lacquer-covered paper layer or a plastic film e.g. of PET, oPP, oPA or cellophane.
  • the plastic film may also bear print deposited using reverse printing.
  • a weakness in the material which serves as a place for initiating the tearing action may be provided e.g. in the form of laser-cut lines which extend over only part of the thickness of the film-type laminate.
  • Another place for initiating tearing is e.g. a tearing notch which is normally situated in a sealing seam.
  • the pouch is normally gripped at two places between finger and thumb of each hand and the opening achieved by a tearing action which is effected by a relative movement of both hands.
  • a known aid-to-opening comprises a notch which is introduced in the packaging line in a sealing seam, normally in the finished pouch.
  • Another known aid-to-opening is such that, prior to pouch production, the laminate is weakened locally by means of laser cutting in the intended area of opening.
  • the barrier layer present may be damaged or a notch may extend into the non-sealed region.
  • an integral barrier layer may be damaged or a notch extends into the non-sealed region.
  • a further disadvantage of the known aids-to-opening in the form of notches and laser cuts is that, even on carefully tearing open the pouch, some of the contents escapes from the pouch during tearing and unintentionally sticks to the hands.
  • the object of the invention is to provide a pouch-type packaging of the kind mentioned at the start which exhibits a manual opening system by means of which it is possible to avoid contamination of the hands with contents escaping from the pouch when the opening procedure is correctly carried out.
  • That objective is achieved by way of the invention in that, in the front wall of the pouch a distance from the sealing seam, a free end of a sealing zone is provid-ed furthest removed from the sealing edge, and at least the front wall of the pouch exhibits an outer layer on the side facing the outside of the pouch, whereby the outer layer and the part of the front wall of the pouch lying under the outer layer delimit an outlet zone for the contents in an area which encom-passes the free end of the sealing zone.
  • the sealing seam is extended in a region bordering the sealing edge and the outlet zone up to a sealing zone directed away from the sealing edge, and the outlet zone extends to a peripheral edge of the sealing edge.
  • the sealing zone and the outlet zone are arranged a distance from the sealing seam and the outer layer exhibits a line of weakness or a separating line as outlet region for the contents to be poured out of the pouch.
  • the outer layer in the outlet zone is bonded to the underlying part of the front wall of the pouch less strongly than it is outside the outlet zone and can be peeled away from that underlying part of the front wall.
  • the outer layer in the outlet zone is freed from the part of the front wall of the pouch lying under the outer layer.
  • the outer layer in the outlet zone is freed from the part of the pouch front wall lying under the outer lay up to a region in the sealing edge and is bonded in the region in the sealing edge to the part of the pouch front wall under the outer layer less strongly than outside the outlet zone and can be peeled away from that part of the front wall.
  • the sealing zone may be in the form of a triangle with its base lying parallel to the sealing edge and sides forming a peak a distance from the sealing edge.
  • the sealing zone may, however, also be in the form of a strip which preferably runs perpendicular from the sealing edge and exhibits a free end.
  • the outlet zone is delimited by two borderlines that run essentially parallel to each other and perpendicular to the sealing edge.
  • the outlet zone may, however, also be delimited by border lines that preferably run towards one end of the sealing seam in the region of a corner of the pouch.
  • the sealing zone is likewise preferably in the form of a triangle with its base lying parallel to the sealing edge and sides forming a peak a distance from the sealing edge.
  • the outlet zone is delimited by two border lines that run essentially parallel to each other and perpendicular to the sealing edge and two border lines that run essentially parallel to each other and parallel to the sealing edge.
  • Packaging films that are suitable as front and rear walls of the pouch exhibit a sealing layer on the side that forms the inner facing side of the finished pouch and can be sealed to each other.
  • the sealing layer may be bonded to a substrate layer via an adhesive.
  • the sealing layer may, however, also be deposited directly on a substrate layer by means of extrusion coating. Under certain circumstances it is also possible to manufacture a sealing layer and substrate layer by co-extrusion.
  • the outer layer on the side of the front wall of the pouch which forms the outer layer in the finished pouch is, in the region out with the outlet zone for the contents, permanently joined by means of an adhesive layer to a substrate layer lying under the outer layer.
  • the outer layer can be peeled away from the substrate layer or is not joined to it. If desired, within the outlet zone, the outer layer may be sealed to the substrate layer in a manner that enables separation by peeling only in the region of the sealing edge and, outwith the sealing edge, be free from the substrate layer.
  • the sealing layer and the substrate layer may form a single common layer.
  • the sealing layer, the substrate layer and the outer layer may also each be in the form of a single layer or be multi-layered.
  • the sealing layers are normally polyethylenes e.g. LDPE, LLDPE, MDPE and mixtures thereof or co-extruded metallocene polyethylenes and inomers e.g. Surlyn®, or co-extruded films of these materials with PE as substrate layer.
  • polyethylenes e.g. LDPE, LLDPE, MDPE and mixtures thereof or co-extruded metallocene polyethylenes and inomers e.g. Surlyn®, or co-extruded films of these materials with PE as substrate layer.
  • polypropylenes may be employed.
  • the thickness of the sealing layers lie in the range of 10 to 100 ⁇ m, preferably 15 to 75 ⁇ m.
  • Suitable substrate layers are foils of metal, in particular aluminium or an alumin-ium alloy. These serve simultaneously as barrier layer against the passage of oxygen, water vapour and aromas.
  • the thickness of the aluminium foil used as a barrier layer for the pouch is approximately 5 to 30 ⁇ m, preferably 7 to 15 ⁇ m.
  • Suitable outer layers are biaxial oriented plastic films of polyesters, polypropyl-ene or polyamide.
  • a preferred polyester is PET (polyethylene-terephthalate) preferably with a thickness of 8 to 20 ⁇ m, in particular 12 ⁇ m.
  • the plastic film employed as outer layer may be printed on the outside and, if desired, be provided with a coating having good sliding properties, or may be counter-printed. Instead of a plastic film, it is possible to employ a paper layer coated with plastic as the outer layer.
  • barrier layer in the form of an aluminium foil it is also possible to employ other barrier layers e.g. thin ceramic layers of silicon oxide and/or aluminium oxide which are deposited by sputtering or by precipitation in vacuum, or plastic films e.g. materials from the series of vinyl alcohols e.g. of ethyl-vinyl-alcohol-polymers or polyvinylidenchloride.
  • barrier layers e.g. thin ceramic layers of silicon oxide and/or aluminium oxide which are deposited by sputtering or by precipitation in vacuum, or plastic films e.g. materials from the series of vinyl alcohols e.g. of ethyl-vinyl-alcohol-polymers or polyvinylidenchloride.
  • the front wall and the rear wall of the pouch may be of the same material or may be different in their layered structure. Normally, the front and rear walls of the pouch are made of the same packaging film.
  • the pouch-type forms of packaging according to the invention are in particular 3 and 4 sealing edge pouches and tube-like pouches featuring one longitudinal and two transverse seams.
  • the scope of the invention includes amongst others a packaging whereby the rear wall of the pouch is in the form of a flexible pouch-type container made by thermoforming or cold forming and having a peripheral sealing and the front wall of the pouch is sealed as lid onto the sealing area.

  • FIG. 14 removal of contents from the pouch shown in FIG. 13 .
  • FIGS. 1 and 2 Shown in FIGS. 1 and 2 is by way of example a version of pouch-type packaging 10 in the form of a so-called 4-sided sealing edge pouch with four sealing edges 16 , 18 , 20 , 22 arranged in a rectangle; the said pouch is comprised essentially of two facing packaging films forming a front side and a rear side of the pouch.
  • the packaging film forming the front side of the pouch hereafter referred to as the front wall 12 of the pouch
  • the packaging film forming the rear side of the pouch hereafter referred to as the rear wall 14 of the pouch, are joined together by an essentially strip-shaped sealing seam 24 running round the pouch-type packaging 10 along the sealing edges 16 , 18 , 20 , 22 thus enclosing a space 13 for the contents.
  • the pouch-type packaging 10 normally contains pourable contents 11 , in particular in a liquid, partially liquid or paste-like form.
  • Pouch-type forms of packaging 10 include e.g. the known pouches for delivering portions of ketchup, mustard, mayonnaise and the like foodstuffs as contents 11 .
  • the strip-shaped sealing seam 24 is extended to a sealing zone 26 in the form of an equilateral triangle with a base line c parallel to the sealing edge 16 and two sides a and b forming a peak 27 a distance e from the sealing edge 16 .
  • the side of the front wall 12 facing the inside of the pouch 10 can be sealed onto the side of the rear wall 14 likewise facing the inside of the pouch 10 .
  • the outward facing side of the front wall 12 features an outer layer 28 .
  • the outer layer 28 adheres to the underlying part 29 of the front wall 12 with less adhesive strength or is free from the underlying part 29 of the front wall 12 .
  • the outlet zone 30 is delimited by a border line 32 running parallel to the sealing edge 16 and two border lines 34 , 36 which run parallel to each other and perpendicular the sealing edge 16 and form the transition of the outer layer 28 from the permanent join to the underlying part 29 of the front wall 12 to the separable or non-adhesive join in the outlet zone 30 .
  • the border line 32 running parallel to the sealing edge 16 is situated a distance f from the peak 27 of the sealing zone 26 .
  • the pouch 10 filled with contents 11 , is pressed from the outside—which in practice is achieved e.g. by pressing the pouch 10 between the thumb and index finger of one hand—then a fold is created in the pouch 10 in such a manner that the tension which acts on the pouch walls that are sealed to each other at the transition from the interior space to the sealing joint, reaches a maximum at the peak 27 of the sealing zone 26 .
  • a rupturing or local separation of this part 29 of the front wall 12 occurs thus creating an opening slit 38 ( FIG. 3 ).
  • FIG. 5 shows that, on applying pressure to the pouch 10 held between the index finger 46 and the thumb 48 of one hand 44 , contents 11 are expressed at the edge 17 of the sealing edge 16 through the outlet opening 42 formed by the part 29 of the pouch front wall 12 and the outer layer 28 . Further, it can be seen from FIG. 5 that the opening in the pouch-type packaging 10 and the removal of the contents 11 takes place by single-handed operation. Thereby, the index finger and thumb effecting the compression of the pouch are situated a distance from the outlet opening such that—as cannot be reliably avoided even on correctly opening conventional pouches—any contamination of the contents is prevented here.
  • the channel 40 formed by the outlet zone 30 and delimited by two boundary lines 34 ′, 36 ′ runs along one side of the triangular-shaped sealing zone 26 to the sealing edge 16 , such that outlet opening 42 is situated in a corner of the pouch at the edge 17 of the sealing edge 16 .
  • FIG. 7 Shown in FIG. 7 is a further version of a pouch-type form of packaging 10 in accordance with FIG. 1 in which, instead of a triangular sealing zone 26 —starting from sealing edge 16 and extending the strip-shaped sealing strip 24 —a sealing zone 26 ′ which projects from the sealing edge 16 or from the strip-shaped sealing seam 24 is provide in the form of a strip with a free end 27 ′ instead of the triangular peak 27 .
  • the free end 27 ′ of the strip-shaped sealing zone 26 ′ is, as in the embodiment with the triangular sealing zone 26 shown in FIGS. 1 to 5 , enclosed by the outlet zone 30 .
  • the outlet zone 30 is delimited by one barrier line 32 running parallel to the sealing edge 1 and two barrier lines 34 , 36 running perpendicular to the sealing edge 16 .
  • FIG. 8 Shown in FIG. 8 is a version of the example shown in FIG. 7 where the channel 40 formed by the outlet zone 30 and delimited by two border lines 34 ′, 36 ′ runs along one side of the strip-shaped sealing zone 26 ′ to the edge 17 of the sealing seam 16 .
  • Rupture tests were carried out on pouch-type forms of packaging with a strip-shaped sealing zone 26 ′ that projects from a sealing edge and serves to provide an opening slit in the packaging film, and the rupture strength deter-mined as a function of the distance X of the strip-shaped sealing zone 26 ′ from a pouch sidewall and of the distance Y of the free end 27 ′ of the strip-shaped sealing zone 26 ′ from the sealing edge 16 .
  • the packaging film employed for production of 4-sided pouches was a laminate having the following structure:
  • the same laminate was used for the front wall 12 and for the rear wall 14 of the pouch; the sealing was made with PE onto PE.
  • the circumferential sealing seam 24 and the strip-shaped sealing zone 26 ′ were produced as corrugated or wave-shaped seal with waves arranged in the direction that the sealing seam 24 runs or in the longitudinal direction of the strip; a flat version of the sealing seam 24 was also made for comparison purposes.
  • the build up of pressure in the pouch until rupture occurred was at a rate of 50 mbar/sec.
  • the results of the rupture tests are presented in table 1 and the calculated product X*Y shown in FIG. 10 as individual values along with the line of regression.
  • the rupture trials make it possible to determine in a simple manner the optimum dimensions and arrangement of the strip-shaped sealing zone 26 ′ required for the lowest possible rupture strength.
  • FIGS. 11 and 12 Shown in FIGS. 11 and 12 is the make up of two packaging films that are suitable for the manufacture of pouch-type forms of packaging 10 .
  • a sealing layer 50 is deposited onto the substrate layer 52 on the side of the packaging film that will face the interior of the finished pouch by means of extrusion coating or bonded to the substrate layer 52 by way of a layer of adhesive.
  • the side of the substrate layer 52 facing the outside of the pouch made from the packaging film is permanently bonded to the outer layer 28 by way of a first bonding material 54 .
  • the outer layer 28 is either not joined to the underlying substrate layer 52 over a bond-free zone 58 , or attached via a second bonding material 56 such that it can be separated by a peeling action.
  • the first bonding material 54 for creating a permanent join is an adhesive based on polyurethane (PU).
  • the second bonding material 56 for creating a separable join is e.g. a hot-melt or a hot-sealing coating.
  • the sealing layer 50 is comprised e.g. of a polyethylene (PE), the substrate layer 52 of an aluminium foil and the outer layer of polyethylene-terephthalate (PET).
  • the make up of the packaging film in FIG. 12 corresponds to that of the film shown in FIG. 11 , except in that here the sealing layer 50 also contains the substrate and is comprised e.g. of a polyethylene.
  • the same packaging film may be employed for the front wall 12 and the rear wall 14 of the pouch.
  • the deposition of the second bonding material 56 to create the separable regions may take place using a printing process e.g. index printing.
  • a sealing zone 26 ′′ in the form of an equilateral triangle with base c lying parallel to the sealing edge and two sides a, b forming a peak 27 ′′ facing away from the sealing edge is provided about in the middle of the front wall, a distance from the strip-shaped sealing seam 24 .
  • the area of the outlet zone 30 for the contents 11 encloses the whole of the sealing zone 26 ′′ and is likewise on all sides a distance from the sealing edge 16 and the sealing seam 24 .
  • the outer layer 28 is provided with a line of weakness or separating cut 37 running through the outer layer forming a slit-shaped open-ing for removing the contents 11 of the pouch 10 .
  • the separating cut 37 runs parallel to the sealing seam 16 and is arranged between the sealing edge 16 and the sealing zone 26 ′′.
  • the outlet zone 30 is delimited by two border lines 32 , 33 running parallel to the sealing edge 16 and two border lines 34 , 36 which run parallel to each other and perpendicular to the sealing edge 16 and form the transition in the outer layer 28 from the permanent attachment to the underlying part 29 of the pouch front wall 12 to the peelable or non-adhesive connection in the outlet zone 30 .
  • the pouch-type packaging 10 shown in FIG. 13 , for removal of the contents through the front wall 12 of the pouch 10 has pressure applied to it from outside by folding the pouch and pressing together the two resulting halves of the pouch, which in practice—as shown in FIG. 14 —is achieved e.g. using the thumb 48 and index finger 46 of one hand.
  • the folding of the pouch 10 is also performed here in such a manner that the tensile force which acts on the pouch walls that are sealed together reaches a maximum at the transition from the interior 13 to the sealing joint at the peak 27 ′′ of the sealing zone 26 ′′.
  • the contents 11 emerge from the interior 13 through the opening slit 38 in the part 29 of the pouch front wall 12 lying under the outer layer 28 and through the outer layer into the intermediate space or channel 40 in the outlet zone 30 and leave the pouch 10 via the slit-shaped opening formed in the outer layer 28 by the line of weakness or line of separation 37 .
  • pouch-type packaging is also to be understood packaging in which the rear wall 14 of the pouch is in the form of a flexible container manufactured e.g. by thermoforming or cold forming featuring a peripheral sealing area and where the front wall 12 of the pouch is sealed onto the sealing area as a lid.
