Definitions

  • the invention relates to a film bag of the type explained in the preamble of claim 1 and a method for filling it.
  • Such a film bag and a method for filling it is known from DE-OS 34 41 947.
  • the known film bag has a filling opening, which is located in the upper edge of the film bag, is slit-shaped and is delimited by edges made of the film material.
  • the side sealing seams are gripped by a clamping device.
  • a suction device is then applied to each of the upper film edges and a vacuum is applied. Then the suction devices are pulled apart, taking the film edges with them, thereby spreading the filling opening.
  • the known film bag thus requires a relatively complex filling device, in which the vacuum pump, in particular, increases the cost of generating the suction pressure. Nevertheless, it cannot be ensured with the known device that all bags can be opened reliably.
  • the invention is therefore based on the object of providing a film bag whose filling opening can be opened easily and without great effort.
  • the object is achieved by the characterizing features of claim 1.
  • the filling opening can be opened stiffening body reliably without the use of vacuum in a purely mechanical manner by compression forces applied to the slot ends of the filling opening, as described in claim 11. Elaborate vacuum devices are no longer necessary.
  • Claims 2 and 3 describe a particularly preferred arrangement and structural design of the stiffening body and the filling opening.
  • the measure according to claim 4 improves the distribution and introduction of the compression force even further.
  • the pointed oval cross section of the stiffening body improves the introduction of the compression force.
  • such a shape is particularly expedient to handle in terms of production technology if the filling opening and the stiffening body are accommodated in the upper edge of the film bag. With this arrangement, a smooth, flowing transition between the body and the film edges to be welded together is created at the tips of the pointed oval cross section, so that the bag can be closed without the risk of leakage openings.
  • the stiffening body can simultaneously take on the function of a pouring spout without having to take any special precautions.
  • FIG. 1 shows a side view of the upper part of a film bag according to the invention
  • FIG. 2 shows the top view of FIG. 1
  • Figure 3 is a schematic representation of the opening process of the film bag
  • Figure 4 is a perspective view of the fully filled and sealed foil bag.
  • a film bag 1 can be seen from FIGS. 1 and 2, which consists of two plastic film blanks lying flat on top of one another and connected by relatively wide lateral sealing seams 2a, 2b.
  • the film cuts are rectangular, at least in the upper area, their upper edge 2c extending from one side sealing seam 2a to the other side sealing seam 2b.
  • In the upper edge 2c of the film bag 1 there is a slot-shaped filling opening 3 which is delimited by unconnected film edges 3a, 3b of the upper edge 2c.
  • the filling opening 3 extends from one of the side sealing edges 2a to beyond the center of the upper edge 2c.
  • a bead 4a, 4b is embossed in each of the film edges 3a, 3b, which, when the filling opening 3 is closed, form an essentially pointed oval opening.
  • a stiffening body 5 is welded into the upper edge 2c of the film bag 1 between the filling opening 3 and the other side sealing seam 2b.
  • the stiffening body 5 is made of plastic and has a symmetrically pointed oval cross section (FIG. 2).
  • the side surfaces of the stiffening body 5 welded to the upper edge 2c run parallel, so that an exact welding into the upper edge 2c of the Foil bag 1 is possible.
  • the stiffening body 5 is aligned in such a way that its two tips 5a, 5b lie in the extension of the direction of the slot-shaped filling opening 3. One of the tips 5a lies against the filling opening 3 and the other of the tips 5b lies against the side sealing edge 2b.
  • the stiffening element can also be used as a pouring aid.
  • Width of the stiffening body 5 in the direction of the upper edge 2c at least 60 mm
  • Width of the stiffening body 5 transverse to the upper edge 2c maximum 16 mm
  • Width of the sealed seam 2a 10 mm
  • Width of the beads 4a, 4b in the direction of the upper edge 2c 10 mm
  • Stiffness to be determined individually.
  • each of the lateral sealing seams 2a, 2b is received in an abutment 9a, 9b.
  • Each of the abutments 9a, 9b is designed as an angular groove, in the angular tip of which the sealing seams 2a, 2b can be positioned exactly.
  • the angular tips of the two abutments 9a, 9b lie on a straight line which extends through the center of the angled channels.
  • the abutments 9a, 9b are provided on compact, block-shaped components 10a, 10b, at least one of the block-like components 10a, 10b being movable in the direction of the other block-like component.
  • a compressive force acting in the direction of the upper edge 2c is exerted on the film bag 1, which bulges the film edges 3a, 3b in opposite directions, which is due to the selected shape and arrangement of the beads 4a, 4b is supported.
  • the filling opening is opened for the introduction of a filling head or for the direct filling of filling material.
  • the film bag 1 can be held in place by additional clamping devices or the like, which are well known in the prior art. After filling, the abutments 9a, 9b are moved apart so that the foil bag 1 is relieved of the compressive force A.
  • the filling opening 3 closes and is welded in the usual way by a sealing seam 11, so that the shape shown in FIG. 4 results.
  • the slit-shaped filling opening can also be arranged at other points on the film bag, for example in one of the side sealing seams or directly in the film blank.
  • the use of the stiffening body is furthermore not restricted to the drawn, essentially rectangular shape of the film bag.
  • the cross-sectional area of the stiffening body can be varied as long as it is ensured that its shape does not prevent the correct introduction of the compression forces into the filling opening.
  • the width of the sealing seam adjacent to the stiffening body can be reduced to a normal size.
  • other suitable, expediently self-centering shapes can be selected. It is also possible to apply the compression force by means of clamping devices which can be moved relative to one another. For bags with different capacities and / or widths, the width of the sealing seam and / or the dimensions of the stiffening body can be modified. If necessary, stiffening bodies can also be provided at both slot ends of the filling opening.

Abstract

Il est décrit un sachet en feuille (1) comportant une ouverture de remplissage en forme de fente (3), laquelle est constituée par des bords de feuille (3a, 3b) juxtaposés et reliables entre eux pour fermer l'ouverture de remplissage. Afin de pouvoir remplir un tel sachet en feuille plus facilement et avec moins d'appareillage, il est proposé de disposer à côté de l'une des extrémités de l'ouverture de remplissage à fente, et en prolongement de la fente, un élément raidisseur (5).
