Definitions

  • the invention relates to a cylindrical inner valve or "hose valve” for sacks for holding bulk goods, such as powdered, granular or dusty goods, with improved closing action.
  • Powder, granulate or dust-like goods such as. As soot, finely divided silica or food such. B. flour, are shipped in bulk bags provided with an internal valve, so-called valve bags. These valve bags usually consist of strong, multilayer paper. They are filled via the internal valve and closed by it.
  • An object of the invention is a cylindrical inner valve for bags for receiving bulk goods, the. Length falls below that of the section of the filler neck of a bagging machine to be inserted into the valve, with a relatively rigid insertion channel and an end piece made of flexible film which forms the valve lips and is characterized in that the valve lips are designed as an adhesive film.
  • the second object of the invention is a cylindrical inner valve for sacks for holding bulk material, the length of which is less than that of the section of the filler neck of a bagging machine to be inserted into the valve, with a relatively stiff insertion channel and an end piece made of flexible film, which forms the valve lips, which is characterized in that the upper valve lip projects beyond the lower by at least the diameter of the valve channel.
  • the valve lips can also be designed as an adhesive film to further increase the sealing effect, as in the case of the inner valve according to the invention presented first.
  • the extension of the upper valve lip compared to the lower one already provides more flexibility when using normal ones Films the advantage that the upper lip, with a suitable bag or tilt position overlaps the lower lip and thus brings about a sealing effect, in - closes normally sufficient transport certainly without the formation of the end piece as adhesion film.
  • the end piece of flexible film forming the valve lips can be made of plastics such as polyethylene, PVC and the like. a. consist. However, thin paper, such as tissue paper, can also be used, provided that the interior valve construction provides the feature of the overlapping valve lips.
  • the flexible end piece can have any length in comparison to the overall valve. It is essential that a part of the same protrudes over the multilayer, relatively rigid paper wall of the inner valve and thus its flexibility is not hindered.
  • the flexible end piece can be arranged on the inner wall or on the outer wall of the inner valve.
  • the individual paper layers of the inner valve can end at different points, i. H. the wall of the inner valve can be stepped to the mouth of the inner valve in the interior of the bag.
  • the flexible end piece can be tubular, its diameter being adapted to the diameter of the inner valve.
  • the latter has a cylindrical shape to correspond to the cylindrical filler neck of the bagging machine.
  • the flexible end piece can consist of one, two or more rectangular foils. If several foils are used, they are adapted to the wall of the inner valve; that their ends overlap. The overlapping parts can be glued in the area of the paper wall of the inner valve and freely displaceable in the area of the flexible end piece.
  • the inner valve according to the invention is matched in length to the filler neck of the packaging machine and is therefore not contaminated from the inside by remnants of the goods to be transported when it is withdrawn from the inner valve.
  • the end of the filler neck 2 projects beyond the end 5 of the inner valve into the paper bag.
  • the inner valve consists of the relatively rigid paper walls that form the insertion channel for the filler neck 3 and 4, between which the flexible adhesive film 6 is glued. Part of the entire length 7 of the adhesive film 6 is located outside the end 8 of the paper walls 3 and 4 and forms the flexible end piece with the valve lips. These can lie in one plane if the end piece is designed as an adhesive film.
  • the upper valve lip 9 projects beyond the part of the adhesive film 6 protruding below by more than the diameter of the valve channel.
  • the former lies around the latter when the filler neck is pulled back, thereby causing the closure.
  • the end piece consists of adhesive film, which further enhances the security of the seal, which is good even with non-adhesive films.
