Definitions

  • the invention relates to a packaging container for bulk material, in particular a bag or a bag made of plastic film, with a bulk material enclosing the container wall, comprising at least one multi-layer venting area of at least one inner layer and an outer layer, wherein the venting region has only one chamber and extending in one of the container main directions, wherein the vent area is equipped with at least one inner opening and one outer opening, and wherein the inner and outer openings is assigned at least one shielding element for deflecting at least a partial flow of the air flow passing through the vent area, wherein the inner opening and the outer opening respectively are formed in a vent region laterally limiting connecting seam.
  • Packaging containers are known, which are used in particular to receive pourable or free-flowing fillings, such as, for example, foods, fertilizers or similar products.
  • the overpacked products are produced, among others, in the food industry or the chemical industry.
  • the filling or bulk goods are transported by means of the packaging container substantially and stored and either brought directly by means of packaging containers on the market or fed through the packaging container for further processing a subsequent manufacturing process.
  • a generic packaging container for bulk material is from the DE 20 2006 020 303 U1 known.
  • the ventilation area has inner openings and outer openings, which lead into a passage area, wherein the passage area is divided into a plurality of chambers connected to each other via at least one passage.
  • the inner openings and the outer openings are made by perforations or needles.
  • the inner opening and the outer opening are produced by interruptions in the longitudinal seams. These interruptions can be achieved by known means during welding or heat sealing.
  • a bag which has a plurality of sealing lines in an overlapping area, which are each interrupted, so that an air path from the inside to the outside is possible.
  • the US 6,170,985 B1 describes a bag made of a weldable plastic, such as polyethylene. The overlapping ends of a film are welded. In this area there are continuous welds in which openings are formed. This creates a labyrinthine channel.
  • the EP 0 895 947 A1 describes a method for packaging to be disposed of good. If waste and leftovers are filled in a packaging container and the filled containers are sealed on their open side, then waste can be transported odor-tight and stored in this way. However, there is the problem or risk that such waste may ferment and thereby produce gas. In order to prevent an uncontrolled bursting of the film containers, a predetermined breaking point is generated in the production of a weld, which breaks open at emerging pressure and thus a controlled gas discharge takes place.
  • the Packaging container has a container wall enclosing the bulk material with a vent area of at least one inner and outer layer.
  • the packaging container is equipped with inner and outer openings, openings being provided in a strip-shaped area of the inner layer as an inner opening.
  • the outer opening is produced in a ventilation seam laterally delimiting seam through which the air entering the venting area is discharged into the environment.
  • the inner and outer opening is associated with at least one shielding element for deflecting at least at least a partial flow of the air flow passing through the venting area.
  • the invention has for its object to show a packaging container that allows optimal ventilation and can be produced at the same time simplified.
  • a packaging container for bulk materials in particular a bag or bag of plastic film with a bulk material enclosing the container wall, comprising at least one multi-layer venting area of at least one inner layer and an outer layer, the venting area having only one chamber and extending in one of the container main directions, wherein the venting region is equipped with at least one inner opening and one outer opening, and wherein the inner and outer opening is associated with at least one shielding element for deflecting at least a partial flow of the air flow passing through the venting area, wherein the inner opening and the outer opening each in a laterally delimiting the venting area Connecting seam are formed, is provided according to the invention that at least the outer opening is formed by at least one weakened seam portion in the connecting seam, so that there is a reduced material connection between the superimposed layers, which can be lifted by a resulting inside the packaging container pressure.
  • an improved inflow process into the venting region is ensured via the inner opening, which is likewise formed in a connecting seam of the venting region.
  • the inner opening which is likewise formed in a connecting seam of the venting region.
  • the inner opening can be dispensed with advantage.
  • it is no longer necessary to need this surface area in a separate processing font during manufacture whereby the production of the packaging container is simplified.
  • the outlet of the air from the interior of the packaging in the venting area via, for example, a single inner opening in the connecting seam, which has a corresponding opening dimension, to ensure an effective venting function.
  • the inner and outer openings can be arranged in each case in different, on both sides of the venting area opposite boundary or connecting seams.
  • the inner openings are formed in a connecting seam by means of which the inner layer of the venting area is fastened on the inner side of the container wall, and the outer opening is formed in a connecting seam, by means of which the outer layer of the venting area is fixed on the outside of the container wall. Due to the formation of the inner and outer openings in the connecting seams with which the respective layers are set on the inside and outside of the container wall, an always effective ventilation from the packaging interior is guaranteed in the environment.
  • the vent area is formed from two individual film strips arranged congruently to one another, the longitudinal edges of which are connected in particular to mutually spaced-apart edge edges of a flat web folded on both sides.
  • the material connection by means of connecting seams represents a permanently secure form of attachment between the layers forming the vent area and the flat web forming the rest of the packaging wall.
  • the venting region is formed from overlapping edge regions of a longitudinally folded flat web, which represents a structurally advantageous possibility for designing the venting region on the container wall of the packaging container.
  • the wall regions With the superimposing of the wall regions, only two connecting seams extending parallel to the edge regions of the flat web are required to form the closed venting region. In one connecting seam is the inner opening and in the other connecting seam, the outer opening of the venting area is provided.
  • the vent area is arranged depending on the type of packaging container to be produced running approximately in the longitudinal or transverse direction on the packaging container.
  • the vent area extends in particular in the longitudinal direction of the packaging container, for example, from the head region towards the bottom region of the packaging container.
  • the vent area extends in the case of packaging containers whose folded edges form, in particular, areas of a standing floor or of a multi-layered head area of the packaging container, then in a horizontal alignment between head and floor area.
  • the horizontally extending vent area may be arranged, for example, halfway up the packaging container.
  • the vent area extends in its actual longitudinal direction always over the total height or the total width of the packaging container, which ensures the optimal ventilation of the packaging interior. It is also conceivable to use a tubular web for the production, which is cut open in the longitudinal direction.
  • the shielding element associated with the inner and outer openings of the venting area is in particular a seam section connecting the inner and outer layer, with which the inner and outer openings, which can be arranged approximately at the same height in the venting area, are separated from each other in the connecting seams at least in regions.
  • a seam portion With the use of a seam portion, a structurally simple possibility for forming the shielding element is provided, via which a direct passage of air from the inner opening to the outer opening is prevented.
  • the seam section or the separating seam is arranged such that the inner and outer openings of the venting area are preferably always concealed from one another by a section of the seam section.
  • the shielding element runs approximately parallel between the lateral connecting seams of the venting region.
  • regions of constant cross-section are provided on both sides and along the shielding element.
  • the cross sections on both sides of the shielding element may have the same dimensions or have different width dimensions. It is also conceivable to align the shielding element formed as a seam section obliquely at a certain angle to the connecting seams running parallel to one another in order to specifically create narrow bottlenecks between the ends of the seam section and a connecting seam immediately adjacent thereto.
  • the inner and outer openings are arranged at predetermined heights on both sides of the shielding, such that a sufficiently large distance or a sufficiently long deflection is ensured for the exiting through the vent area from the interior into the environment airflow. This is intended to improve the separation of entrained particles in the air flow.
  • Inner and outer openings and the shielding can be arranged together at any height on the vent area.
  • the shielding element may for example also, based on the height in the longitudinal direction of the venting region, be arranged approximately centrally and is thus flowed around at both its ends of the exiting air flow.
  • the inner and outer openings are formed correspondingly on both sides of the shielding element at a corresponding height in the connecting seams.
  • the shielding element and the inner and outer openings are preferably arranged in at least one end section of the venting area, wherein the shielding element terminates, in particular, on a transverse seam delimiting the venting area.
  • Such an inventive arrangement of the shielding and the inner and outer openings in relation to the filling, upper end portion of the venting area has the advantage that the venting of the packaging container is guaranteed until the end of the filling. Possible damage to the packaging container, such as tearing, can be avoided with advantage.
  • the filling of a packaging container takes place with a venting area oriented in its longitudinal direction, in particular from its top or bottom area.
  • the filling with the filling or bulk material is carried out via one of the side areas.
  • a optimal subsequent forced ventilation ensured by means of, for example, a press belt.
  • the shielding element arranged in the end section or region preferably runs directly on a transverse seam delimiting the venting region in its direction of extent.
  • the transverse seam is, for example, a head or bottom seam or a side seam of the packaging container.
  • Inner and outer openings may be formed, for example, at a distance of a few centimeters to the transverse or side seam in the usually orthogonal to the seam extending boundary or connecting seams.
  • the shielding element arranged or formed in the interior of the venting region has a length of at least 5% of the total height of the venting region.
  • the inner and outer openings are sufficiently shielded from each other.
  • the air flow passing through the venting area experiences an effective deflection at the at least one free end of the shielding element, which is arranged in particular in an end section of the venting area. Over the correspondingly long path between the inner opening and outer opening thus a discharge possible entrained with the air flow filling material particles is prevented in the environment.
  • the shielding preferably has a maximum length of 60 percent of the total length of the venting area.
  • the shielding element thus extends a maximum of a little more than half the total height of the venting area, so that the venting area always comprises only a single chamber. Accordingly, the venting region has an advantageous deep-drawn deflection region for the air flow, in which also filling material particles can be deposited without difficulty. With over more than half of the total length extending shield If necessary, it may be necessary to equip the shielding element with a weakening in a section adjacent to the transverse or side seam.
  • the weakening in a forced ventilation of the packaging container by means of a press belt prevents damage to the packaging container.
  • the weakening may be, for example, a release paint partially applied in the region of the separating seam between the inner and outer layer.
  • the shielding element preferably has a length of 10 to 50 percent of the total height or overall length of the venting area.
  • the inner and outer openings are formed by means of at least one interruption in the ventilation area laterally limiting connecting seams, which is a relatively easy way to implement the inner and outer openings in the connecting seams.
  • Each inner and outer opening may be formed from one or more juxtaposed interruptions in the connecting seam.
  • Each seam can also be an adhesive seam, in which case the application of adhesive is interrupted in the region of the openings.
  • the outer opening can be created by means of at least one weakened seam section in the completely closed connecting seam.
  • a weakening agent such as release lacquer or the like, is applied to a surface piece assigned to the outer opening of at least one of the mutually facing surfaces of the inner or outer layer of the venting region prior to the production of the lateral, respectively associated boundary seam.
  • the superimposed layers go in this Range by the attenuator then an advantageously reduced interfacial connection with each other.
  • This compound can, as well as the compounds in the weakening of the shielding be canceled by a resulting inside the packaging container pressure, which may arise in particular in the forced ventilation.
  • the inner opening instead of a seam interruption, be formed by means of such a weakened seam portion in the inner joint seam.
  • the multi-layer vent area between the inner and outer layer is equipped with spacers.
  • spacers With the use or the formation of spacers between the inner and outer layer of the venting area, a safe escape of the process air, which has reached the packaging container together with the filling material, from the packaging interior is always guaranteed.
  • About the spacers can be a predetermined minimum distance between the inner and outer layer generate, with which can be avoided possible adhesion forces between the facing surfaces of the layers of the venting area.
  • the spacers are formed as embossments in at least one of the superimposed layers, which is a structurally simple way of creating spacers.
  • the embossings can be provided both in sections and over the entire length and width of the venting area extending at one of the layers.

  • a shielding element 14 is provided, which separates the inner opening 10 and the outer opening 11 from each other in regions, thus avoiding a directly rectilinear passage of air through the venting area. With the help of the shielding element 14 also a targeted deflection of the venting region 7 passing air flow is effected. Possible entrained with the air flow filling material particles are to be deposited by the deflection of the air flow from this and remain between the inner and the outer layer 8, 9.
