Definitions

  • the invention relates to a bottom gusseted bag with two side surfaces, with a V-shaped bottom folded inwards, with longitudinal seams which extend at least to the V-fold and with at least four lateral, inclined bottom seams, each with only one side surface with a V- Connect the legs of the bottom and have a starting point lying on the corresponding longitudinal seam at the level of the bottom fold.
  • the above embodiment can be found in DE-B-1 2 81 140.
  • the four side bottom seams are arranged at an angle, while the longitudinal seams also extend across the height of the bottom and here connect all four layers of foil.
  • the top of the bag is open or closed with a cross seam.
  • the bottom gusseted bag can be made from a single film web or from three film webs.
  • DE-A-26 13 724 discloses a gusseted bag which has a square bottom and which can be produced from two sheets of film.
  • the flattened bag is rectangular in plan view, the inner folds of the two inserted between the side walls front wall and rear wall butt against each other.
  • the side walls each consisting of a single rectangular section, are connected with their vertical side edges to the corresponding edges of the front wall and rear wall, and with their lower transverse edge to an opposite transverse edge of the square base.
  • the latter has a weld or sealing seam running all around, consists of a single film web section together with the front wall and the rear wall and, when the bag is laid flat, is folded triangularly into the interior of the bag via its diagonals.
  • the film width for flat sheets is usually a maximum of 1.30 m. If the bottom gusset bag explained at the beginning were produced from only one flat web, the bag height would thus be limited.
  • the invention has for its object to improve the bottom gusset bag explained in terms of its uses and its manufacture.
  • This object is achieved according to the invention in that it is formed from at least two film parts and has a cover designed according to the bottom, in which four side cover seams run obliquely according to the bottom seams, and that a side surface and the adjacent V-leg of the cover are extended beyond the top edge of the lid and together form a filler or emptying nozzle (spout) with longitudinal seams.
  • the bottom gusseted bag according to the invention can be produced from e.g. thermoplastic foils that are heat sealable. One then speaks of sealed seams.
  • the thermoplastic plastic films can also be weldable. One then speaks of separating seam welds.
  • seam most often used in this application is intended to include the two alternatives mentioned above, while the term “gluing” is also intended to include “sealing” or "welding”.
  • thermoplastic plastic films can be formed in one layer and e.g. are made of polyethylene or polypropylene. But they can also be multi-layered; it is then a question of composite films.
  • Other possible starting materials are paper-plastic composites that are heat-sealable, plastic-plastic films that are cold-sealable, and plastic-coated paper webs that are cold-sealable or heat-sealable.
  • film most commonly used in the application is intended to encompass all possible alternatives.
  • the longitudinal seams also extend over the height of the floor. as well as the cover and in this area connect only its side surface with a V-leg of the bottom or the cover.
  • two or more longitudinal seams arranged next to one another at a distance can be advantageous, the longitudinal strips thus formed being folded inwards onto one or the other side surface and glued to it. In principle, it is possible to reverse the folding or in the same direction.
  • a reinforced adhesive strip is inserted between the folded longitudinal strips and the associated side surface.

  • the intermediate bottom which divides the bag into two chambers and consists of a fifth film part, and a second spout on the bottom.
  • This intermediate bottom can in turn be folded in a V-shape, the edges of the V-legs being connected to the side surfaces of the bag via corresponding seams.
  • the intermediate floor can also consist of a closed hose or e.g. be designed as a filter.
  • the new bottom gusseted bag is inflated or filled, its bag body will automatically inflate. Not only the filled, but also the only inflated empty bag are absolutely stable.
  • the new bag can be shaped, sealed or welded, filled and closed fully automatically on a form, fill and seal machine; it can also be packaged as an empty bag and then Round fillers can be filled and sealed as a solo pack or in a cardboard box.
  • the bottom gusseted bag according to the invention offers i.a. the main advantage that it inflates automatically during filling, so that the outer carton, which is expediently only slightly formed for cost reasons, does not have to be mechanically erected into the filling state by an erecting machine. In addition, gluing between the inner bag and outer carton is no longer necessary, which saves further costs.
  • the new bag can be filled up to the lower edge of the filling or emptying nozzle and thus completely, so that no empty space or air space remains. That is why the bag body maintains its stable shape even when evacuating.
  • the spout provided on the new bag enables the finished packaging to be reclosed and thus also gradually emptied.
  • the bag can be easily sealed airtight after it has been filled by welding or sealing the spout opening.

  • the bottom gusset bag also has two longitudinal seams 3, which extend over the entire height of the side surfaces 1.
  • four sloping bottom seams 4 are provided, which only extend in the zone of the W, which is formed by the side surfaces 1 and the bottom 2.
  • Each bottom seam 4 connects only one side surface 1 to a V-leg of the bottom 2 and has a starting point 5 lying on the corresponding longitudinal seam 3 at the level of the bottom fold 2a.
  • a cover 6 designed in accordance with the bottom 2 is provided, the four side cover seams 7 of which also run obliquely.
  • the one side surface 1 'and the adjacent V-leg of the cover 6 are extended beyond the transverse edge of the cover and together form a filler or emptying nozzle 8 (spout) with longitudinal seams 9.
