Definitions

  • the present invention relates to a stabilized, flexible, cubic container, comprising a continuous and punched tubular base part, its unfilled volume in the corner areas with external material adaptations is provided, the inner open edges immediately behind the punched covering tightly connected to the base part by means of material connections are.
  • a generic, stabilized, flexible, cubic container is, for example, known from WO 93/14007.
  • the tubular base part becomes one Material layer produced by connecting two edges. Connecting is not only time and thus costly, but can also become a vulnerability in the Guide the container.
  • the container can only be made of one fabric and not can be made from plastic films, since the use of seams as in this container are provided when using plastic films too would cause leakage.
  • the invention was therefore based on the object, the generic, stabilized, to further develop flexible, cubic containers in such a way that the Disadvantages of the container produced by known methods does not have.
  • This task is solved by teaching the main claim.
  • This type of construction is opposed for the previous or later introduction of a stabilized belt stabilization using a continuous inner tube as a starting point of production achieved.
  • This basic concept has the advantage that everyone Start further manufacturing steps on the outside of a seamless base hose can.
  • Another advantage over other manufacturing methods is that Avoiding many weak points that can occur during the subsequent internal welding of a belt, for example Seam tears due to peeling tension, welding defects and Position inaccuracies, contamination by opening a hose.
  • the stabilizing column of the continuous base hose is in accordance with the invention weakened by no inner seam approach. Also Position shifts are not possible because no belt is inserted at all. The inner surface of the base hose remains protected from contamination because of the Hose does not have to be opened.
  • the external material adaptations in the form of Flat films or half-tubes also guarantee a low particle content Production. All subsequent additions are made from the outside Base hose attached.
  • the base tube which as a gusseted tube is a tubular element represents, must have suitable and sufficient number of punched holes in order to later filling a smooth flow of material into the pockets forming to ensure external material adaptations. The same applies to emptying.
  • the tubular film is over the individual gussets Material webs fed from outside.
  • These can either be 8 flat foils or 4 Be half hoses.
  • Half tubes are created by a slit on the side Tubular film or congruently folded flat films. By a slight Opening of the half-tubes reaches one side in the top and bottom Foil of the base tube.
  • Outer pockets which correspond to the entire length of the later container by means of Longitudinal welding above and below with the base hose or the covering the respective hose side fold immediately behind the punched-out areas get connected.
  • These additional outside pockets then fill the corner room a later container, as far as it from the inner, space-reduced tubular film cannot be reached.
  • Plastic films are primarily considered as materials. But also other materials (e.g. paper) can be used. Suitable as a connection method welding technology is preferred for plastics, but also other seams and Adhesive connections can be considered.
  • Containers stabilized in this way are not only suitable for large containers, but also also for smaller containers, if the filling material changes shape there Bulging of the wall. So far, this expansion effect has been in many Avoid cases only by using thick-walled outer packaging. Now you can do the desired with a thin protective jacket cubic package shape is retained.
  • the shape of a stabilized inner shell is variable. Different Side lengths are also possible, as are filler and outlet spouts of any shape. With the correct dimensioning of the inner tube column is a very good stability can be achieved, so that there may be completely on an outer packaging can be dispensed with.
  • the overlap is through material adaptations 3 in the form of flat foils 3A or half tubes 3B the respective hose folds advantageous (Fig. 2; Fig. 6).
  • the inside open Ends 5 of the half hose must be from the outside with the surface of the base hose 1 can be connected.
  • flat foils they must be attached to the outer edges are also closed.
  • the type of material connection 4 or 4A depends on the selected sheeting. When unfolded forms the tubular base tube 1 with those connected on its outside Material adaptations 3 in cross section a square surface (Fig. 3).
  • the Connection points 4 are shown in detail in FIG. 3.
  • the section is shown in Fig. 4.
  • the connection points on the The outer skin of the base tube 1 is to be understood continuously as a seam, so that the in the unfolded state pockets forming material adaptations 3 only via the Punchings with product can be filled and emptied.
  • the product can be used in the Material adaptations 3 forming pockets do not emerge, since the web ends through continuous seams 4 are connected to the base tube 1 or in the case of Use of flat foils 3A subsequently on the outer edges 4A be closed by welding. This is shown in Fig. 6.
