Definitions

  • the invention relates to a sack consisting of a rectangular Blank is made from paper or foil, as well as a process for its manufacture, filling and sealing.
  • the bag is particularly suitable for filling with powdery filling goods intended.
  • the filling of powdered goods into sacks and the subsequent closing of the bag closures some problems that are addressed below.
  • Here are usually used for closing, especially with paper bags Hot melt adhesive applied to the closure surfaces and glued them together or in the case of from existing bags of thermoplastic films lying on top of each other Closure surfaces thermally welded together.
  • valve bags are widely used in one A valve sleeve is glued into the bottom of the cross at one end.
  • the disadvantage of such bags is the reduced filling speed, through the valve cross section into which a filler neck of a few centimeters in diameter is limited is.
  • the manufacturing and recycling is done Use of the additional valve sleeve more expensive.
  • the filling speed can be adjusted increase, but it is the total closure surface dusted after filling, so that the closure cannot always be error-free.
  • a dust covered one Surface hinders both gluing with hot melt adhesives as well as welding the surfaces of thermoplastic Foils.
  • Another problem is that with powdery filling filled sacks which, for example, can be filled after the alb filling a block or cross bottom fold are closed to the Impact corners have micro-openings, which canals with the Inside the sack are connected, from which filling material emerges can and especially about pests in food Can find access.
  • An empty according to the invention and for transport before opening and filling certain flattened sack is characterized by it from that for the closure first flap and second Sealing flaps are formed, each at the ends lying gussets in pairs - forming one in one Flat sealing collar formed from the four flaps - are connected to form sealing corners.
  • first sealing flaps with respect to the bag walls, to which they connect to the outside of the bag opening turned away while second flaps related to the sack walls to which they connect and which usually form the shorter sack walls, towards the inside of the sack opening have turned over.
  • the compound of the invention i. H. Gluing or welding the gusset to the ends of the Sealing flaps with each other, so it takes place before filling of the sack, so that a hermetic, flawless 'sealing' the corner areas of the bag lock ensured is.
  • the type of handling of the first sealing flaps according to the invention and the second closing flap related to the bag opening leads to the free opening cross section on the sack Feeling is not reduced compared to a conventional open bag, because with this an essential part of the sack flag outside a filler neck for holding and handling available must be, so that the effective free opening cross-section is considerable is below the theoretical; compared to a valve bag however, there is a much larger filling cross section Available.
  • the formed by the said tabs in The frame-shaped sealing collar is located on one level Possibility of a filler neck on this for all-round sealing Bring plant, making an outside of effective Area lying in the sealing line can be kept dust-free, so that also in this area after the filling process perfect 'sealing' is possible.
  • the sealing corners can be according to a first preferred embodiment be formed by some kind of corner, as they are arise when, as already described, the first sealing flaps folded outwards at right angles from the first sack walls and second sealing flaps of second sack walls inwards at right angles to it, d. H. coming to lie on the sack opening to be folded.
  • a crease edge Gusset at the ends of the first and second flaps to cover and each with originally on a same Side of the raw material lying surfaces in plant.
  • the gusset areas in contact form the Basis for the 'sealing' of the sealing corners Can be glued or welded.
  • each of the first and second closure flaps have end edges, d. H. be independent of the respective closing flaps.
  • the first sealing tabs run much wider to accommodate to create a handle opening.
  • the flaps of this type can be produced by cutting the edges of the raw material, which are essentially capable of the aforementioned Corrugated edges correspond.
  • the edge incisions limited gusset at the ends of the first and second Sealing flaps to cover and each with originally surfaces lying on the same side of the starting material in Appendix. Form the gusset areas in contact the basis for the 'sealing', this by gluing or can be done by welding.
  • the bag body can be preformed as a gusseted bag be, the second sack walls and the second sealing tabs inwards between the edge areas of the first sack walls are folded.
  • the sack can also be as simple Flat bag should be folded so that the second bag walls and second sealing flap outwards outside the edge areas the first sack walls are folded down.
  • the sack body that is spread apart or filled have a substantially rectangular cross section, the by the position of the corners, or the one defined thereby Length of the first and second sealing flaps is determined.
  • the bag bottom can be of any design, for example a common cross floor. However, it is also an easy one straight-line gluing or welding in the manner of a seam closure possible.
  • the sealing collar is folded out again and into one configuration at right angles from the bag body.
  • the first two sealing tabs are used for clamping and holding the bag to the sealing collar.
  • the one held sack can be transported, filled and in a hanging position if necessary be weighed. Filling the sack does the trick the spreading of the sack immediately.
  • a cover sheet can be placed on the bag opening be sealed all around with the sealing collar can be.
  • a cover sheet can be flat on the frame-like collar surface or with its longitudinal edges glued or welded to the first flaps and with its transverse edges against folded sealing strips glued the free edges of the second flap or be welded.
  • the transverse edges of the cover sheet can also be folded up into sealing edges.
  • a sack in this condition is completely hermetic in the closure area completed so that the subsequent connection of the first Sealing flaps with each other by turning each other over in the manner of a seam closure or by laying them together the inside of a bag or handle closure only the Bracing and hardening serves while the dustproof 'Sealing' through the production that took place before filling the sealing corners and the placing of the after the filling Cover sheet is already ensured.
  • adhesive orders according to the desired type of bag bottom appropriate.
  • one on the opposite longitudinal edge running closure area are four gusset areas with Apply adhesive, each delimiting between first or second closing flap of the folded bag mark and later form the corners.
  • the gusset-shaped Glue applications can be on the first sealing tab or be made on the second flap.
  • the closure area will be of uniform width, the locking corners then by the multiple described Turn the first flap over onto the second flap takes place along a crease edge. If the first flaps and the second flaps are different Should have width or if there is a kink between the flaps
