Definitions

  • the invention relates to a packaging bag for liquid, pasty and granular materials, consisting of four in the region of their side edges, as well as their lower edges and at least partially their upper edges sealingly interconnected film sections made of flexible material to form a front wall, a rear wall and two side walls, the limit the interior of the bag between them.
  • Packaging bags for liquid, pasty and granular substances are known in a variety of configurations. They can be designed, for example, as contour bags, standing bags, tubular bags, paper bags or also as cardboard-like packaging, such as milk cartons. Coated paper and plastic or metal foils are used as materials for such packaging bags, which can be designed as monofilms or composite films.
  • the contents provided determine the material from which the packaging bag can be made.
  • Other factors that determine the construction material are the quality of the desired presentation, the possibility of free-standing, the type of transport, the strength of the packaging, the recycling options and the cost.
  • the known packaging bags are mostly unsatisfactory in at least one of the ways described above.
  • it has so far not been satisfactorily possible to produce a packaging bag with the features mentioned at the outset in such a way that it stands safely and freely at least after filling and has an aesthetically satisfactory appearance.
  • the invention has for its object to design a packaging bag with the features mentioned so that it is free and in stable equilibrium after filling on a flat surface. Furthermore, the packaging bag should be constructed as simply as possible, have a satisfactory aesthetic appearance and there should be the possibility of providing it with a device for reclosing, which is constructed only from the material of the packaging bag itself.
  • closure devices such as screw closures or hinged closures
  • closures are expensive and cause difficulties during recycling, since these closures are usually made from materials other than the packaging bag itself.
  • the basic idea of the invention is to design the packaging bag in such a way that its side walls have somewhat different mechanical properties than the front wall and the rear wall, in the sense that the side walls are less flexible than the front and rear walls.
  • this design results in that when the packaging bag according to the invention is filled, the pressure exerted on the inner walls has a different effect on the side walls than on the front wall and the rear wall.
  • the front wall and the rear wall deform more than the side walls during filling.
  • the lower ends of the side walls are folded inwards under the influence of the material weight and form a flat and stable base on the underside of the packaging bag during the further deformation of the front wall and the rear wall, which leads to the packaging bag being firm and stable after filling stands on a flat surface.
  • the different stiffness of the side walls with respect to the front wall and the rear wall can either be achieved by using a different material for the side walls than for the front wall and the rear wall, or it can be used for the Side walls are made of the same material, only foil sections of different thickness are used for the side walls and the front and rear walls.
  • the currently used film thickness will depend on the size of the packaging and the density of the content, as well as, for example, the desired shape of the content.
  • the materials used for the front wall, the rear wall and used for the side walls of the packaging bag can be monofilms made of plastic, paper, treated paper or cardboard.
  • composite films can also be used which consist of different plastic films, possibly together with metals, paper or cardboard.
  • non-bonded parallel layers made of different materials can also be used.
  • the film sections of the side walls consist of a composite film which has a plastic layer on the outside of the bag with a higher heat sealing temperature than a plastic layer arranged on the inside of the bag.
  • the plastic layer on the outside of the side wall can be made of polyester and the plastic layer on the inside of the side wall can be made of polyethylene.
  • a particularly well-standing packaging bag is achieved if all four film sections have edges which are at right angles to one another at least at the end facing the underside of the packaging bag and are connected to one another at these edges in such a way that, in the view from below, the bag in the unfilled state has a double T -shaped shape.
  • This training has the consequence that the downward folding parts of the side walls form a particularly large contact area.
  • the packaging bag can have a rectangular configuration when viewed from the front, while it can have a more triangular shape when viewed from the side by bringing together the upper edges of the front wall and the rear wall.
  • a particularly stable packaging bag is achieved if the film sections are connected to one another via welded or adhesive seams such that the outer edges of the film sections connected to each other point in the same direction.
  • welded or glued seams give the bag a special stiffness, the welded or glued seams depending on the size of the packaging bag being 3 to 15 mm wide.
  • the packaging bag from a tubular film, a certain greater rigidity of the side walls being achieved simply by virtue of their smaller width.
  • the packaging bag according to the invention is particularly simple Way on the top of the bag, a removal opening closed by a tear-off or cut-off closure can be arranged.
  • This removal opening can be arranged, for example, in the region of one of the upper corners of the bag, so that after the closure has been torn off or cut off, a pouring spout can be produced by folding out the upper end of the one side wall.
  • the interior of the bag in the area immediately before the removal opening is designed as an outlet channel running towards the upper edge, and at least a partial section of this outlet channel in a strip-like manner delimited from the outer contour of the bag Opening tab is arranged, at the outer end of which the tear-off or cut-off closure is arranged.
  • the reclosure can then be achieved by arranging in the bag a holding slot which passes from the front wall to the rear wall and is sealed off from the interior of the bag, the length of which is adapted to the width of the opening tab and the width of the opening tab and its position on The bag is such that the folded opening flap can be pulled through the holding slot with at least part of its length.
  • the 1 to 3 has a front wall 1, a rear wall 2, and side walls 3 and 4, which are constructed from rectangular film sections.
  • the film sections forming the side walls 3 and 4 have a greater rigidity than the film sections forming the front wall 1 and the rear wall 2.
  • All film sections can be formed as a composite film with an outside made of polyester and an inside made of polyethylene. The latter facilitates that described below with reference to FIGS. 16 to 22 Production method.
  • the greater rigidity of the side walls 3 and 4 can be achieved in that the corresponding film sections have a greater thickness than the film sections of the front wall 1 and the rear wall 2.
  • the front wall and the rear wall can be made of a 75 ⁇ m thick polyethylene film consist, while the side walls are formed from a polyethylene film with a thickness of 150 ⁇ .
  • the front wall and the rear wall can be formed from a polyethylene-aluminum composite film with a thickness of 75 ⁇ , while the side walls from a polyethylene-aluminum-polyester composite film with a thickness of 125 ⁇ are produced.
  • FIG. 1 to 3 show the packaging bag in the already filled state.
  • the lower ends 3.2 and 4.2 of the side walls 3 and 4 have folded inwards and form a flat support which enables the bag to stand securely and stably on a flat surface.
  • the upper ends 3.1 and 4.1 of the two side walls are against folded inside, so that the bag has an approximately triangular shape when viewed from the side.
  • the front and rear walls are welded to the side walls along the upper edge 6 of the bag.
  • the corners 7.1 and 7.2 between the side wall 3 and the front wall 1 on the one hand and the rear wall 2 on the other hand can then be folded out in the direction of arrow A and the upper center 3.1 of the side wall can be pulled outwards in the direction of arrow B, so that, as in FIG shown, a pouring spout for the contents of the packaging bag is created.
  • the packaging bag shown in FIGS. 1 to 3 represents the simplest embodiment in terms of construction and manufacture.
  • a packaging bag is shown, which is constructed in principle exactly the same as the packaging bag according to FIGS. 1 to 3, and differs from this only in the design of the pouring part.
  • the left corner is not cut off at an angle, but the bag has on its top a tear-off or cut-off tab 8, the outer edge 6.1 of which is welded in a sealing manner and to which the likewise welded upper edge 6 of the bag is connected.
  • a tear-off tab 8 projecting upward from the contour of the bag, as can be seen from FIGS. 5 and 6, by folding out the two upper corners 7.1 and 7.2 of the side wall 3 in the direction of arrow A and pulling out the middle end 3.1 of the side wall 3 to the outside, a pouring spout of maximum size can be produced.
  • FIGS. 7 to 9 shows a packaging bag which is particularly suitable for thinner liquids.
  • it is provided with an outlet nozzle which has a smaller outlet cross-section, although the side walls 3 and 4 have the same width as in the embodiment according to FIGS. 4-6.
  • the bag in the upper left corner has a tear-off or cut-off tab 9 which protrudes beyond the contour, after its cutting the upper corners 7.1 and 7.2 of the side wall 3 are folded outwards and the center 3.1 of the side wall 3 , as can be seen from Fig. 9, can be pulled outwards.
  • the smaller discharge cross-section is achieved in that the width of the front and rear wall of the packaging bag is somewhat reduced in the upper region 3.3 of the left side wall 3. A comparison of FIGS. 7 and 4 shows that this results in a smaller outlet cross section.
  • FIGS. 1 to 9 The embodiments of a packaging bag shown in FIGS. 1 to 9 are not resealable.
  • an embodiment of a packaging bag is shown, which is resealable.
  • the otherwise analogous to the prescribed Embodiments of packaging bags have a strip-like opening tab 10, which projects beyond the upper edge of the bag with a tear-off part 10.3.

  • the seal of the bag is ensured at this point by appropriate welding of the material.
  • a holding slot 11 is arranged parallel to the longitudinal slot 10.2 and somewhat deeper than it, which likewise penetrates both the front wall 1 and the rear wall 2 and, by means of welds 11.1 arranged around it, the tightness with respect to the interior of the bag is also ensured here.
  • the length of the retaining slot 11 is adapted to the width of the opening tab 10 and its width is adapted to the thickness of the opening tab 10.
  • an outflow spout 10.1 can be formed, as can be seen from FIG. 11 and already described, through which the contents of the bag can be emptied. If the emptying spout 10.1 is only partially emptied, the opening flap 10 can be folded back in the manner shown in FIG. 12 and inserted through the retaining slot 11. In this way, the bag is closed again and can be pulled out of the holding slot by pulling the opening tab 10 11 can be opened again.
