Definitions

  • the invention relates to a gusseted bag or sack made of flexible material for pourable filling material after the Preamble of claim 1.
  • gusset bags or sacks of this type exist made of paper, plastic film or multi-layer or Composite materials
  • the plastic films, metal foils and Layers of paper can include and are filled after with the pourable, e.g. granular, filling material that may be in a separate bottling company takes place at their head end seamlessly with each other or with the adjacent one Side gusset half closed on the inside.
  • Training this connection or closure seam at the head end is preferably done with the help of a bag manufacturer along the top of the head end on the inside of the bag applied hotmelts or heat seal adhesive, by heating to form a seal seal is activated. If the inside of the bag itself is in the desired degree of heat sealable quality Has formation of the sealing seal seam, however, can such hot melt orders are omitted and the sealing seam directly at the top of the bag using the usual sealing jaws are made.
  • the gusset For this pushing the gusset back into the Position they originally in the closed headboard of the bag, usually not from there the elasticity of the usual bag material the gusset can jump open more or less and so creates an opening to the inside of the bag that is effective Protection of the contents is prevented.
  • the invention has for its object a gusseted bag or sack of the type specified at the beginning create a safe reclosure of the Dump opening after a filling with simple Means.
  • the gusseted bag shown in the drawing is made for example paper, e.g. in two layers, with each other between the two layers of paper opposite U-shaped support bracket 1, which in turn can consist of, possibly tissue-reinforced, paper on Head end 2 of the bag with a suitable protrusion are glued over the upper edge 3 of the head end 2.
  • the bottom end 4 of the bag is by a block or Block floor closed, in its place basically other floor closures, e.g. a changing floor, kick can.
  • the bag further comprises a bag front wall 5 and a bag rear wall 6 and extending between them, the side folds forming the bag side walls 7 and 8, the one shown in FIGS.
  • Fig. 1 the bag is in the use state to carry or storing the filled packaging before the first filling material is removed shown.
  • the head end 2 is along the upper edge 3 on the inside by a heat seal or Weld 13 closed by heating a Hotmelt order 14 formed in a limited range is.
  • the hot melt order 14 and with it the heat seal seam 13 extend across the entire width of the bag and create a connection between the inside of the Bag walls 5 and 6 with each other or with the adjacent one Gusset half 7a, 7b.
  • a discharge opening 15 (Fig. 2) is the Inner fold edge 12 of the side fold 7 a handle 16 on upper bag edge 3 for pulling out the side fold 7 while loosening the connecting seam 13 between the bag walls 5, 6 and the adjacent side gusset half 7a, 7b provided.
  • the handle 16 has in the embodiment 1 to 5 the shape of a Projection 17 opposite the upper edge of the bag 3.
  • the projection 17 is in the manner of a flap on both sides of the inner folding edge 12 to an area adjacent to it Gusset 7 limited and in the state of use Fig. 1 laid flat against each other in half.
  • the bag is shown in the use state, in which by pulling out the side fold 7 the dispensing opening 15 is formed.
  • the gusset 7 is as in the filling area of the bag, also in the area of the Head end 2 and transition area 9 spread flat apart, the inner fold edge 12 in a fold line 12 '' re-shaped according to the fold line 12 ' Has.
  • the two mirror-symmetrical ones are also stretched flat Halves 17a and 17b of the projection 17 on both sides the inner folding line 12 ''.
  • Around a lower transverse fold line 18 of the transition region 9 is the flat gusset 7 on both sides of the inner folding line 12 '' for completion the discharge opening 15 in the manner of a spout slightly bent outwards.
  • the discharge opening 15 are on both sides of the inner folding edge 12 according to FIG. 1 and the Folding line 12 '' according to FIG. 2 two triangular corner corners 19 and 20 by means of a diagonal folding line 21, 22 formed from the base of the inner folding edge 12 to Connection point of the transverse folding line 18 with the outer folding edge 10 or 11 of the gusset 7 and extend the Corner tabs 19, 20 the shape of isosceles rectangular Convey triangles in double-layer training, since they are congruent from the bag front wall 5 with the adjacent gusset half 7a and Bag rear wall 6 with the adjacent side gusset half 7b are formed.
  • FIG. 3 shows this reclosed state of the discharge opening 15, on the outside of the bag walls 5 and 6 fixed corners 19 and 20 with diagonal folding edges 21 ', 22', predetermined by the diagonal folding lines 21, 22 are.
  • the sections or orders 23, 24 of the adhesive are on the area of the triangular tips of the corner tips 19, 20 and the congruent triangles 25 of the bag front wall 5 or the bag rear wall 6 limited by the corner tips 19, 20 when they are about their diagonal folding line 21, 22 folded over onto the outside of the bag walls 5, 6 are covered.
  • the sections or orders 23, 24 of the adhesive cover each other, whereby the adhesive bond between the corner tips 19, 20 and the bag walls 5, 6 is produced. This is with particular clarity from the enlarged individual representations 4 and 5 can be seen.
  • Blank 26 of a reinforcing material identified the in the area of the gusset 7 between the upper edge of the bag 3 and the transverse fold line 18 with the Inside of the bag material e.g. connected by gluing is.
  • the blank 26 reinforcement material comprises in particular a metal foil, preferably an aluminum foil, which to form the discharge opening 15 used part of the gusset 7 an increased Rigidity and therefore good formability for training the discharge opening 15 mediated by hand as a spout.
  • the blank 25 On the inside facing the inside of the bag the blank 25 is a heat sealable layer with which an easily peelable heat seal connection between the 25 side gusset halves covered on the inside 7a, 7b and the inside of the adjacent bag wall 5 or 6 in the course of attaching the sealing weld 13 can be produced.
  • the formation of a heat sealable Layer in such a way that by heating this heat seal seam formed easily peelable (peelable) can be carried out in a manner known per se appropriate setting of the for the heat sealable Layer of thermoplastic used, e.g. Polyethylene or polypropylene.
  • the projection 17 used as a handle 16 is as a one-piece extension of the bag, in the preferred Use of the reinforcement blank 25 from a composite material formed from the actual Bag material, e.g. Paper, and the reinforcement material blank 25 is composed. This is in FIG. 4 and 5 due to the fact that the projection 17 is also included Oblique hatching clarifies.
  • the projection 17 can be closed again the discharge opening 15 around its base line 17c (FIG. 2) be folded over to the inside of the bag.
  • the Corner corners 19, 20 in turn around their diagonal folding lines 21, 22 folded over and with the aid of the adhesive sections or orders 23, 24 on the outside of the bag wall 5 or 6 set, the projection 17 in turn on the upper edge 3 of the bag, straddling these, be opened and thereby acting in the closing sense Tension as hold-down force on the upper edge of the bag 3 exercise.
