Definitions

  • the present invention relates to a bag according to the preamble of claim 1.
  • the known bags are provided with a pouring device which is arranged in the area of a corner so that the bags can be opened by severing a corner section.
  • a channel is formed solely by a pouring tube which is inserted and welded in parallel to the longitudinal edge 4 between the front and rear wall of the bag.
  • a preformed channel through deep drawing of the film parts is not available here.
  • the pouring pipe is placed against the weld seam of the longitudinal edge 4 between the film parts to determine its position and then the film parts are welded together on the opposite longitudinal side of the pouring pipe by means of a longitudinal seam, the film parts being pulled as closely as possible over the pouring pipe and the The weld seam must be made as close as possible to the pouring pipe.
  • Such an embodiment is disadvantageous. It is difficult to apply the last-mentioned weld seam close to the tube and thereby make it tight. Wrinkles can appear in the film parts. It would also be technically very complex to arrange the channel obliquely in the last solution, similar to the first solution mentioned, since then means for determining the position of the pouring tube are missing. So that the outflow of the container contents is good, the diameter of the pouring tube should not be too small, especially in the case of highly viscous liquids. In pouring pipes with a suitable and therefore larger diameter for fulfilling this purpose, cracks can occur in the film parts due to stretching of the film parts or the pipes are flattened if the longitudinal weld seam is as close to the pipe as desired. So that the film parts do not tear, a thicker film would have to be selected for the bag. However, this is not desirable to save film material.
  • the CH patent specification 677 093 describes a further solution which is intended to remedy the disadvantages indicated as far as possible.
  • an elaborate injection molded part is welded into the upper end of the film bag, which holds the film walls apart by means of wings and has a pouring channel.
  • the elaborate, custom-made injection molded part makes the entire bag more expensive.
  • the object of the present invention is to provide a solution that is as simple as possible with minimal use of raw materials, the collapse of the film parts in the region of the pouring device being prevented and a clearly defined channeling of the emptying of the container contents being to be obtained.
  • the inserted tube reinforces the zone in the area of the pouring device and prevents collapse.
  • the thickness of the bag film no longer needs to be matched to the stress in the area of the pouring device. It can be matched to the load from the content and thus made thinner. This saves raw material.
  • the tube is no longer overloaded and a cheap, commercially available tube can be used, the inside diameter of which can now be matched to the desired outflow properties of the container contents and advantageously chosen as large as possible for highly viscous liquids.
  • the bag can thus be made from one relatively thin film material can be produced, in which only a tube section is used as a foreign body.
  • the recess in the bag walls does not have to follow the contour of the inserted tube everywhere. It can also have any suitable formations which bring about further improvements against the collapse of the bag walls in the pouring zone.
  • the inner tube end is preferably preceded by a cavity-shaped bulge widened with respect to the tube, which bulge opens into the inner tube end and is embossed in at least one side wall of the bag in order to prevent the entrance zone from being closed to the tube by collapsing.
  • the bag is generally emptied in one operation.
  • a bag of the type in question here consists of a thermoplastic plastic film which is cut so that the side walls 1 and 2, as well as a W-shaped folding base known per se (see EP-0 368 145 and EP-0 364 373), which are joined together at the edges 3 by welding, gluing, heat sealing, etc., in order to produce a closed bag.
  • the bag need not be made from a single piece of film. So the bottom of the bag can be made of a separate film of the same or different quality and / or thickness than the walls.
  • the bag is also provided with corner seams at the corners in the area of the folding bottom. The corner seams are placed over the corners and each connect only one folding floor section to the directly opposite section of the front or rear wall. As a result, the outer folding edges form the edges on which the filled bag stands.
  • the folding base sections lying directly next to one another are preferably connected to one another by oblique corner seams.
  • the bag can be provided with a pouring device of different designs, as described below.
  • the pouring device shown in FIG. 1 comprises a pouring channel 4 and a tube 5 which is arranged in the pouring channel.
  • the pouring channel 4 is half formed by groove-shaped depressions which are formed in the side walls 1, 2.
  • Channel 4 is enclosed by a seam 6 placed over the corner section such that the upstream end of the pouring channel 4 lies outside this seam 6 and forms an inlet section 7.
  • the tube 5 is dimensioned such that in addition to the inlet section 7 there is an outlet section 8 of approximately the same size at the downstream end of the tube 5.
  • the tube 5 is fastened at the points designated 9 in the pouring channel 2.
  • a line 10 marked with the scissor symbol is attached to the outer surface of the bag, along which a section can be separated from the bag in order to open the latter.
  • nose-shaped depressions according to FIG. 2 can also be provided in the side walls 1, 2, in which the tube 5 is arranged and held.
  • FIGS. 3 and 4 show a second embodiment of the pouring device for the bag according to the invention.
  • the pouring device comprises a pouring channel 11 and a tube 13 which is arranged in the pouring channel 11.
  • the upstream end of the channel 11 opens into a pear-shaped space 12.
  • the channel 11 and the space 12 are each formed in half by depressions which are formed in the side walls 1, 2.
  • the tube 13 is so in the channel 11 arranged that the outlet section 8 is formed at the downstream end of the tube 13 and that the upstream end of the tube 13 projects into the pear-shaped space 12 which forms an inlet section.
  • the tube 13 is held in a region 14 of the channel 11 which adjoins the space 12, and is essentially displaceable in the axial direction.
  • the seam 6 is placed close to the wall of the channel 11 in this area 14, so that the tube 13 is guided.
  • the tube 13 is provided at both ends with a bead or flange 15 to secure the tube 13 against removal.
  • the dividing line 10 is placed such that the tube 13 can be grasped when the bag is opened.
  • the main advantage of this solution according to the invention can be seen in particular in the fact that after the tube 13 has been pulled out, a pouring spout can be created, as a result of which refilling of the contents of the bag is facilitated without the advantages of outflow being lost.
  • FIGS. 5 to 6 show a third embodiment of the pouring device for the bag according to the invention.
  • the pouring device comprises a pouring channel 21 and a tube 22 which is arranged in the channel.
  • the upstream, inner end of the channel 21 opens into a lenticular space 23.
  • the channel 21 and the space 23 are each formed in half by depressions which are formed in the side walls 1, 2.
  • the tube 22 is fixed in the channel 21 so that the outlet section 8 is formed at the downstream end of the tube 22 and that the upstream end of the tube 22 projects into the lenticular space 23, which has an inlet section forms.
  • the dividing line 10 is placed in such a way that it passes immediately in front of the downstream end of the tube 22.
  • a perforation 24 can also be provided on the corner section in such a way that a pouring spout 26 is created by tearing off section 25, as shown in FIG.
  • FIG. 7 shows a fourth embodiment of a pouring device for the bag according to the invention.
  • the pouring device is similar to that shown in FIG. 5 and comprises a pouring channel 21 and a tube 22 which is arranged in the pouring channel, the pouring channel 22 likewise opening into a lenticular space 23 with the upstream end.
  • the tube 22 is connected in the region of the upstream end by the seam 6 on the circumference to the side walls 1, 2 and closed at the downstream end by the seam 6. Between these points, the tube 22 is exposed in the pouring channel 21.
  • the dividing line 10 is placed in such a way that when the bag is opened, a section 29 of the tube 22 is cut off in addition to the corner section part 28. Furthermore, a perforation 30 is provided which ends in the area in which the tube 22 lies freely in the pouring channel 21.
  • the perforation is first torn open and then the bag is cut along the dividing line 10. This creates a pouring spout that is similar to that shown in Figure 6.
  • the corner section is punched out in the form of a beak and the corner seam 6 follows the beak-shaped contour of the corner section.
  • the embodiment is essentially of the same configuration as in FIGS. 5 and 7 and like parts are designated by like reference numerals.
  • the tube 22 extends over the entire length of the preformed channel 21 and lies closely along this length against the channel walls.
  • the cavity 23 formed in the side walls 1 and 2 is approximately bean-shaped and it opens directly into the inlet end of the tube 22 with a gentle narrowing.
  • the embodiment according to FIG. 8 can also be provided with an angled channel and tube and / or with a locking pin.
  • the film walls made of thermoplastic material are heated and the pouring channel 4, 11 or 21 and the adjoining cavity 12 or 23 are molded into the heated film walls in a manner known per se in a deep-drawing process using vacuum, compressed air and / or stamps.
  • the cylindrical plastic tube 5, 13 or 22 is then inserted into the pre-shaped pouring channel and the weld seam 6, which is placed over the corner, as well as the other weld seams 3 are applied, with the exception of an area left open for filling the filling material.
  • the inserted tube is spot-welded to the side walls in order to fix its position in the pouring channel.
  • the inner end of the tube preferably ends approximately at the inner boundary of the corner seam 6.
  • the pouring channel as shown at 7 in FIG. 1, is extended inwards relative to the tube 6, or a bulge or cavity is placed in front of the pouring channel or tube, as in 12 in FIG. 3 and at 23 5, 7 and 8, which in the tube 6 opens.
  • the bag is filled with filling material up to about the height of the corner seams.
  • a closure pin can be provided which can be inserted into the outer end of the pouring channel or the tube.
  • pouring devices shown do not necessarily have to be arranged in a corner section. They can also be located on another suitable edge section of the bag.
