Definitions

  • the invention relates to a packaging bag made of flexible material, in which at least one of the two ends of the bag is closed by a cross or block bottom with pairs of opposing corner inserts and bottom side envelopes, which for carrying the bag in the filled state with a carrying handle in the form of a lengthwise direction in the bottom direction the outer floor level, with its end areas fixed to the floor, is provided with a hand-pullable strap.
  • Packaging bags made of flexible material such as plastic film or paper with a handle are known in numerous embodiments for packaging a large variety of different products.
  • a carrying handle which in the filled state of the packaging bag presents a carrying loop running approximately in the outer bottom plane, has the advantage that such carrying handles do not disturb the storage and, if they do not stand out from the packaging bag even when empty, the shipping of the empty packaging and in particular do not hinder their filling in the bottling plant with the help of the respective filling apparatus.
  • the invention has for its object to provide a packaging bag made of flexible material with a carrying handle, the carrying loop from its basic position lying in the outer bottom plane of the packaging bag can be comfortably gripped by hand regardless of the filling condition of the packaging bag by the user; at the same time, a simple mechanical attachment option of the carrying handle to the bag bottom should be possible.
  • this object is achieved according to the invention in that the grip strip with its end regions on the outside fixes at least one of the two bottom side envelopes and the carrying loop with a Z-shaped insert in the grip strip when it is pulled off the ground dissolvable material storage fold is provided.
  • the carrying strap in its filled state, can be conveniently thanks to its Z-shaped material storage fold and effortlessly grasp it by hand and pull it off the floor, as the material storage fold loosens and the hand of the user has an enlarged carrying loop due to the material lengthening of the grip strip in this area.
  • the Z-shaped design of the material storage fold ensures that the carrying loop does not protrude in its basic position from the outer bottom plane of the cross or block bottom, or at least not to an extent that disturbs the handling of the packaging and its filling.
  • the handle must have the durability appropriate to its use.
  • the grip strip forming the handle can be formed in two or more layers in a manner known per se by folding strip parts against one another, it being possible to bring about a special strength of the grip strip if, as provided for according to a further feature of the invention , reinforcement threads are fixed between the grip strip layers at least in the longitudinal edge regions of the grip strip which are delimited on the outside by folded edges.
  • the packaging bag according to the invention can in particular consist of a suitable paper packaging material, in which case the grip strip also consists of a packaging material made of solid paper or cardboard.
  • a packaging bag designed in this way is unproblematic with regard to disposal of the empty packaging bags after use of the filling material, in particular by composting and recycling in the so-called recycling, since such a packaging bag consists of materials of the same type which do not introduce a disruptive factor in the recycling process.
  • the reinforcing threads in the grip strips which may be used, can consist of an ecologically harmless material such as cotton.
  • FIG. 1 shows a packaging bag made of flexible material, for example paper, designated as a whole by 1, which is formed by a side gusset tube section 3 closed by a longitudinal seam 2, the side gussets of which are designated by 4.
  • a block bottom 5 is formed, which has corner inserts 6 and 7 lying opposite one another in pairs and bottom side envelopes 8 and 9 lying opposite each other in pairs.
  • a corresponding, so-called cross-shaped base is created when the base is molded onto the end of a tube section at which the Gussets 4 are missing.
  • a carrying handle in the form of a grip strip 10 is provided, which extends in the longitudinal direction of the block bottom 5 approximately in its outer floor plane, is fixed with its end regions 11 to the block bottom 5 and a carrying loop 12 which can be pulled off the block bottom 5 by hand between the end regions 11, which is kept free of a connection, in particular an adhesive, to the block base 5.
  • a flat material web 13 for example a paper web
  • Adhesive applications 14 are applied to the material web 13 in the longitudinal length corresponding to the bag length in the transverse orientation in each of those areas of the material web 13 which are used to form the outer bottom side turn 9 of the block bottom 5.
  • the adhesive applications 14 preferably consist of a customary starch-based adhesive to be processed at room temperature, but they can in principle also consist of a hot melt adhesive if instead of a paper web a plastic film web forms the material web 13.
  • the preformed grip strips 10 are placed on the adhesive applications 14, so that the end regions 11 are glued to the material web 13 will.
  • prefabricated reinforcement sheets 16 are in turn placed over the respective grip strips 10 on the adhesive orders 14, which are sized accordingly in their order format, the reinforcement sheets 16 enclosing the end regions 11 of the grip strip 10 glue to the material web 13.
  • the material web 13 is then closed in a manner known per se to form the longitudinal seam 2 to form a tube web, from which the tube pieces 3 are separated along transverse dividing lines which adjoin the glued-on grip strips, and the block base 5 is molded onto the respective tube piece end, whereby the bottom side envelopes 8 and 9 are bonded to one another.
  • the bottom side envelopes 8 and 9 overlap each other almost completely, i.e. by floor width, and the floor gluing is made between the outside of the bottom side envelope 8 folded inward to close the block bottom and the adjacent surfaces of the corner folds 6 and 7 and the inside of the outer bottom side envelope 9 then folded inward, which on the outside already corresponds to that on the Material web 13 attached grip strips 10 carries.
  • the arrangement is such that the grip strip 10 runs essentially symmetrically on both sides of the longitudinal center line 17 of the block base 5, indicated by dash-dotted lines in FIG. 1.
  • an off-center arrangement of the grip strip 10 closer to the outer folded edge 18 of its bottom cover 9 could also be chosen, for example with a lower degree of overlap of the bottom covers 8 and 9 than shown in the example according to FIG. 1.
  • the carrying loop 12 which flat and spans the outside of the bottom-side envelope 9 in its basic position shown in FIGS. 1 and 5, is bounded at both ends by the respectively adjacent edge 19 of the reinforcing sheets 16.
  • the end regions 11 of the grip strip 10 each extend over the adjacent diagonal folding edge 20 of the associated corner wrap 6 or 7 in a direction perpendicular to the carrying loop 12 towards the adjacent bottom side folding edge 18.
  • Such a folding around the diagonal fold edge 20 is of course not necessary if, as is possible in principle, the end regions 11 and the reinforcing sheets 16 are shortened in the longitudinal direction of the floor (FIG. 5) such that they end in front of the corner or folding edge 20 of the bottom side cover 9 .
  • a Z-shaped material storage fold 21 is inserted into the carrying loop 12 of the grip strip 10 and forms an outer material gusset 22 and an inner material gusset 23 between the adjoining layers of the Z-fold.
  • a punctiform adhesive for example hot melt, can be introduced between the two layers of the outer material gusset 22, which fixes the two layers of the gusset 22 to one another in order in this way also to carry the carrying loop 12 to keep under difficult handling conditions, especially in the filling operation, in the area of the outer floor level of the block base 5 and to prevent a disturbing protrusion.
  • This adhesive connection in the outer gusset 22 of the Z-fold is dimensioned such that it is easily destroyed when the carrying loop 12 is gripped and pulled off by hand and the Z-fold 21 is dissolved as a whole, in such a way that it is separated by the Z-fold stored material length of the grip strip 10 unfolded to a comfortable size of the carrying strap 12 ', as can be seen for example from FIGS. 3 and 4.
  • the grip strip 10 comprises several layers 24, 25 and 26 by folding strip parts against one another and that its longitudinal edges are delimited by outer folded edges 27. Adjacent to these folded edges 27 and possibly also in intermediate areas, reinforcing threads (not shown) can be incorporated into the grip strip 10.
  • FIG. 4 shows that by means of the folding edge 19 of the reinforcing sheets 16 facing the carrying loop 12 in each case Edge seam 28 is formed, in which a reinforcing thread (not shown) can be fixed near the folded edge 19. This effectively reinforces the floor area immediately adjacent to the carrying loop 12 or 12 'and prevents the carrying handle from being torn out even with high payloads.
  • the block bottom 5 provided with the grip strip 16 can finally be provided with an outer bottom cover sheet 29, as shown in FIGS. 3 and 4.
  • the bottom cover sheet 29 is glued to the outside of the block bottom 5 and provided with an opening 30 exposing the carrying loop 12 so that the user's hand can grasp the carrying loop 12 from the outside.
  • FIG. 6 to 9 illustrate another type of manufacture of the packaging bag 1 provided with a handle, in which a prefabricated handle unit 31 is combined with the packaging bag 1, which is in turn prefabricated, or the block base 5 thereof.
  • a flat web 32 made of paper, plastic or the like is assumed, in which the exposure openings 30 are provided in the longitudinal widths corresponding to the bottom width of the packaging bag 1.
  • the flat web 32 the width of which corresponds to the base length of the packaging bag 1, is conveyed through several work stations in the longitudinal direction in accordance with the movement arrow 33.
  • the exposure openings 30 are made in a work station I by means of a co-operating punching device 34 comprising circumferential punching tools
  • longitudinal adhesive strips 35 are applied to the flat web 32 on both sides of the exposure openings 30 by means of an adhesive applicator 36.
  • prefabricated reinforcement strips 37 are applied to the longitudinal adhesive strips 35 using a pressure roller 38 and thereby glued to the flat web 32.
  • the reinforcement strips 37 each have on their side facing the exposure openings 30 the reinforcement seam 28 with a reinforcement thread 39 inserted and fixed therein.
  • the handle strips 10, which in turn have been preformed, with the inserted Z-shaped material storage fold 21 are applied transversely to the longitudinal direction of the flat web 32 on the reinforcement strips 37 in alignment with the exposure openings 30 by means of suitable adhesive applications by means of a lay-on roller 40.
  • the flat web 32 is divided by transverse separating lines 42 running centrally between the exposure openings 30 or the grip strips 10 into the individual carrying handle units 31, the width of which can correspond to that of the block bottom 5 of the packaging bag 1 which has itself been prefabricated; however, the width and / or the length of the carrying handle unit 31 may also be selected to be smaller than the base width and / or length.
  • this carrying handle unit 31 comprises the base sheet 29 with the exposure opening 30 and the reinforcing sheets 16 and the handle strips 10, which extend continuously between the transverse separating edges of the carrying handle unit 31 and the handle strips 10, the reinforcing sheets 16 depending on the strength of the handle strip 10 or the loads to be carried are possibly unnecessary.
  • the side of the carrying handle unit 31 carrying the reinforcing sheets 16 and the grip strips 10 is provided in an application device 43 with an adhesive application 44 which spares the exposure opening 30, but which is otherwise full-surface and via a transfer cylinder 45 which is in Direction of arrow 46 rotates, a packaging bag 1 transported in the direction of arrow 47 is fed in order to be glued with its side carrying the adhesive application 44 to the block base 5 which has been folded and glued by closing the bottom side envelopes 8 and 9 (FIG. 1).
  • FIGS. 8 and 9 shows in the left half in its upper area the reception of the handle unit 31 and in the right half with its lower area the placement of the handle unit 31 on the block base 5.
  • the handle unit 31 can be connected to the block bottom 5 of the packaging bag 1 with particular advantage in the manner described, it goes without saying that the handle unit 31, with or without reinforcing sheets 16, is connected in an equally advantageous manner to packaging containers of another type, i.e. in particular can be glued.
  • packaging containers of another type i.e. in particular can be glued.
  • Molded bottoms of packaging bags come into consideration, but also wall areas of such packaging bags that are suitable for carrying the filled packaging, as well as the packaging or the packaging container itself, not necessarily made of paper , Plastic or the like.
  • Flexible material must exist, but can consist of other packaging materials, for example cardboard.
  • the invention therefore also extends to such prefabricated carrying handle units with the possibility of their attachment to any suitable surfaces of packaging containers of any kind.
  • the end 48 of the bag tube 3 opposite the block bottom 5 is open in the embodiment shown. It enables the packaging bag 1 to be filled from this open end in the filling operation, the open end 48 then being closed there in a suitable manner.
  • the end of the bag 48 can also be provided with a block bottom analogous to the block bottom 5, but without a handle and instead with a filling valve, that after filling in the filling operation brings about an automatic closure or in some other way is locked on the outside. With such a packaging bag closed at both ends by block bottoms, it is in principle also possible to incorporate the filling valve into the bottom carrying the carrying handle in the course of the bottom formation.
