Definitions

  • the invention relates to a packaging system for pourable liquids, powders and granules, in particular pourable food.
  • DE 69910428 T2 describes a packaging container made of polyethylene and aluminum with a laminated tubular multilayer packaging material.
  • a further problem with prior art packaging containers is that when the package is opened, air flows into the package and the contents of the packaging container come into contact with the surrounding air, which in particular in the case of liquid foods, brings about various chemical processes and can lead to a reduced shelf life and thus to a faster perishability of the liquid content.
  • EP 0 746 507 B1 discloses a form of bag-like packaging containers, which consist only of the flexible bag and have no outer jacket, are poorly stackable and insufficiently stable against external pressure, since they are loose in the carton and thereby take no load, but the Prevent entry of air into the container.
  • the object of the present invention is therefore to provide a packaging system for pourable liquids, powders and granules, in particular pourable foodstuffs, which after use enables a simple recycling into the recycling loop and potentially a more cost-effective production.
  • the durability of the contents of the packaging container is to be increased. In this way, the known problems of packaging containers according to the prior art should be overcome. This object is achieved by the technical teaching of the independent claims. Advantageous embodiments of the invention are specified in the dependent claims, the description, the figures and the examples.
  • the object underlying the invention is achieved by a packaging container for pourable liquids, powders and granules, which has an outer shell, an inner flexible bag with an outlet opening and an outlet part connected to the inner flexible bag, wherein the inner flexible bag is connected to the outlet part via a weld, via an adhesive connection or by casting, and wherein the outlet part connected to the outer jacket via a weld, an adhesive connection, a punching operation, a connector, a clamping device or via the introduction of a guide wire is.
  • the packaging container according to the invention preferably consists of an outer jacket, which encloses the inner bag in parts or all, preferably a cardboard or a hard shell but can also be made of fabric or other natural materials and plastics, an inner flexible bag with an outlet and from a consists with him connected outlet part.
  • the inner flexible bag can either be separated from the outer shell by pulling on the outlet part connected to it, or it can be separated or removed by opening the hard shell or by means of special tearing or separating mechanisms.
  • the outlet part is integrally connected to the flexible bag, in particular welded.
  • the bag can indeed be cut open, but does not necessarily have to be cut open.
  • a clear mechanism is predetermined in a self-cutting variant of the packaging container so that the slicing process can take place in a controlled manner.
  • the outlet part advantageously also has no further sealing devices, such as sealing ribs or sealing rings, which as a rule can only lead to leaks.
  • the preferred one-piece design of the flexible bag with the outlet part makes such predetermined breaking points as further sealing devices superfluous.
  • the outlet part can preferably be inserted into at least one rail, which is arranged on the outer jacket. This can ensure that the outlet part is firmly seated and, for example, does not rotate when it is turned on.
  • the rail is not round, but particularly preferably designed rectangular, which can be prevented any rotational movement of Auslasteilils.
  • the outlet part is advantageously shaped so that it can engage complementary in the rails of the outer shell.
  • no valve is provided in the region of the outlet opening.
  • the packaging container according to the invention can be made much cheaper and easier.
  • a valve is needed to prevent the leakage of liquids and prevent after pouring that contaminated with germs surrounding air into the container.
  • the packaging container of the present invention has the advantage that dispensing without subsequent inflow of germ-laden air is possible even without a valve, since the flexible inner bag collapses during pouring and therefore no negative pressure is created in the packaging container, which could provide an inflow germinated air.
  • the wall thickness of the outer jacket is advantageously in a range of 0.1 to 2 mm, in particular in a range of 0.15 to 1 mm. If the wall thickness is below this range, there is a risk that the packaging container will be slightly pressed when gripping the packaging container. If the wall thickness is above this range, the container becomes heavier and more expensive due to the greater material thickness.
  • the wall thickness of the flexible bag is advantageously in a range of 0.02 to 0.5 mm. Below this range, it may be easier to cause injury to the bag due to mechanical influences and thus to a leak. Above this range, it may happen that the higher wall thickness and thus the greater rigidity of the flexible bag prevents complete emptying, for example by collapsing the bag.
  • the packaging container preferably has a size in a range of 5 to 50 cm, calculated on the basis of the two points of the packaging container, which are furthest apart.
  • the packaging container is particularly well suited for products such as food or cosmetics intended for end users.
  • the inner flexible bag preferably has between 2 to 3 layers of plastic or metal. These layers are preferably laminated or laminated. This can prevent the layers move against each other in a partially empty bag and impede the emptying.
  • the outlet part is in direct physical contact with the outer shell or with the shell integrally formed rails. This has the particular advantage that, in contrast to solutions from the prior art, an additional component such as a holder for the outlet opening, which would have to be used only in the outer shell, is not necessary. This can prevent leaks and reduce manufacturing costs.
  • the flexible bag preferably has a molded-on rigid component which has a diameter at least at one point which is larger than the outlet opening. This can prevent the flexible bag from pouring out of the contents, such as a liquid of the bags, from the outlet opening.
  • the material of the outer shell is preferably cardboard or cardboard or a plastic.
  • the outer shell preferably has no or no closed coating or foil on its inside which would make the inside leak-proof to liquids. This has the advantage that over the known containers of the prior art, a further processing step and also costs can be saved.
  • the outer jacket can be designed, for example, in this way continuously for air or liquids, so that mold formation can be prevented in the interior of the outer shell between the flexible bag and the outer jacket.
