Definitions

  • the present invention relates to a bag-shaped package (stand-up pouch/do-yo bag) formed by folding and gluing a paper or cardboard blank, having two side panels that are connected to one another in the region of a bottom edge of the respective side panel to form a bottom region.
  • the two side panels each have two side edges via which they are directly connected to one another, the two side panels defining a closable bag opening in an opening region of the side panels opposite the bottom edge.
  • the invention relates to a method for mechanically filling such a bag-shaped package.
  • Pouch-shaped packaging is commonly used as sales packaging, filled with lumpy, liquid, or powdered goods, or smaller sub-packaged products, and offered to end consumers.
  • Such packaging is typically made of film and is therefore also referred to as film pouches or film stand-up pouches.
  • Suitable packaging machines exist for the automatic filling of film pouches or film stand-up pouches.
  • One such packaging machine is known, for example, as the Robert's IMP 1500 (Cloud Packaging Equipment).
  • This packaging machine includes grippers that grip a film pouch from the side and then enlarge its opening by moving the grippers toward each other, thus pressing the film pouch open.
  • the object of the present invention is to enable the packaging of goods in bag-shaped packages made of paper or cardboard using packaging machines suitable for film bags.
  • the packaging according to the invention can be gripped mechanically at the side edges of the two side panels.
  • the material of the side panels can be bent.
  • the embossed lines facilitate the bending of the material, so that where the embossed lines are located, the material can be bent more easily than in areas further away from the embossed line(s).
  • the side panels can move away from each other in their respective opening areas.
  • the embossed lines thus make it possible to reliably enlarge the bag opening by mechanical compression.
  • the embossed lines reduce the risk of one of the two side panels lying plane-parallel to the other side panel when pressed together, or of creases forming that impair the appearance of the packaging and thus close the bag opening instead of opening further.
  • the packaging can be filled and then sealed mechanically.
  • the bag-shaped packaging made of paper or cardboard according to the invention enables the packaging of goods with a packaging machine suitable for film bags.
  • the embossed lines are embossed into the respective side surface in such a way that an indentation is formed on the outside of the packaging and/or a raised area is formed on the inside of the packaging.
  • embossed lines can further assist in enlarging the bag opening when the side edges are pressed together.
  • the two side surfaces each have at least two embossed lines which are embossed into the respective side surface, but along which the material of the paper or cardboard blank is not folded.
  • the at least two embossed lines of a side surface are arranged transversely to one another.
  • Such a non-parallel arrangement of the embossed lines allows the embossed lines to form opposing regions in which the material can be bent more easily than in other regions. This makes it possible to promote a convex curvature of the side surface when the side edges are pressed together, which is different in the base region than in the opening region.
  • the distance between the at least two embossed lines of a side surface increases from the base region toward the bag opening. This can promote a convex curvature of the side surface when the side edges are pressed together, which is smaller in the base region than in the opening region.
  • Such an embodiment has proven particularly advantageous when the two side surfaces of the bag-shaped packaging are relatively strongly coupled in the base region—for example, when the two side surfaces are directly connected to one another via their base edges.
  • the distance between the at least two embossed lines of a side surface decreases from the base region toward the bag opening. This can promote a convex curvature of the side surface when the side edges are pressed together, which is greater in the base region than in the opening region.
  • Such an embodiment has proven particularly advantageous when the two side surfaces of the bag-shaped packaging are relatively weakly coupled in the base region—for example, when the two side surfaces are indirectly connected to one another via a base surface.
  • the at least two embossed lines are arranged in two groups, with the embossed lines of one group being arranged parallel.
  • the side surfaces each comprise at least four embossed lines which are embossed into the respective side surface, along which the material of the paper or cardboard blank is not folded.
  • At least two of the embossed lines are arranged parallel to one another and thus form one of the aforementioned groups.
  • the groups make it possible to expand the more easily bendable region of the side surface in a direction perpendicular to the direction of extension of the embossed lines. In this respect, it is possible to form larger regions of the side surfaces in which the material can be bent more easily.
  • the embossed lines of a group are of different lengths. Providing embossed lines of different lengths within the same group increases flexibility in adjusting the easily bendable region of the side surface.
  • the embossed lines of a group are arranged such that they are at an identical distance from the bottom edge and at different distances from the bag opening or opening area.
  • the two side surfaces are connected to each other in the region of the bottom edge directly via the bottom edge of the respective side surface.
  • the two side surfaces are indirectly connected to one another via a base surface which extends between the base edges of the two side surfaces.
  • the volume of the packaging can be increased in the base region, so that a bag-shaped packaging with an overall larger volume can be obtained.
  • the bag-shaped packaging can be designed in the manner of a stand-up pouch.
  • the base surface can form a base for the packaging on which the packaging can stand.
  • feet can be provided in the base region of the side surfaces, on which feet the packaging can stand. The feet can, for example, be designed as projections of the side surfaces in the base region.
  • the two side surfaces in the opening area each have a connecting surface for irreversibly connecting, in particular by gluing or sealing, the two side surfaces, so that The bag-shaped packaging can be closed via the bag opening after filling.
  • the packaging can be closed via the connecting surfaces after filling to form a ready-to-sell sales package. This closure prevents goods from falling out or being removed from the sales package.
  • the connecting surface is preferably arranged at an upper edge of the respective side panel so that the side panels can be connected by the connecting surfaces at their upper edge. The bag opening is thereby closed.
  • At least one of the two side surfaces in the opening region comprises an opening aid, in particular a perforation strip or a tear-off thread, via which the sealed packaging can be opened.
  • an opening aid in particular a perforation strip or a tear-off thread, via which the sealed packaging can be opened.
  • a user of the sales packaging in particular after purchasing the sales packaging with the goods contained therein, can open the sales packaging in order to remove the goods contained therein.
  • the opening aid is preferably arranged between the respective connecting surface of the side surface and the base region, so that the interior of the bag-shaped packaging can be made accessible without breaking the connection between the connecting surfaces.
  • the opening aid preferably extends from a first side edge of the side surface to a second side edge of the side surface opposite the first side edge.
  • only one of the two side surfaces has an opening aid, so that after the opening aid has been opened, the connected connecting regions remain connected to one of the side surfaces that does not have the opening aid. This can prevent small-sized waste and/or enable reversible reclosure of the packaging.
  • the two side surfaces each have means for irreversibly connecting the two side surfaces.
  • These means preferably comprise a tab and a recess in one side surface into which the tab can be inserted.
  • the tab is preferably arranged in the connection region in which the two side surfaces are irreversibly connected to one another. After opening the packaging using the opening aid, the region comprising the tab can be folded over in the direction of the recess and the tab can be inserted into the recess.
  • the recess can be round, oval or slit-shaped.
  • the recess is preferably provided on the side surface which has the opening aid. This offers the advantage that the tab can be connected to the other side surface can remain connected to a container that does not have an opening aid. By folding over the other side with the flap, the packaging can then be reversibly closed.
  • the two side surfaces in the opening area each have a recess for hanging the packaging, in particular a Euro hole according to DIN EN 13010.
  • the material of the paper or cardboard blank can be made from a fiber-containing cardboard grade of any grammage.
  • the material of the paper or cardboard blank has a grammage in the range from 200 g/m2 to 300 g/m2, preferably in the range from 220 g/ m2 to 260 g/ m2 , in particular in the range from 220 g/ m2 to 240 g/ m2 or in the range from 240 g/ m2 to 260 g/ m2 .
  • the material of the paper or cardboard blank can be designed as a GZ or GT material.
  • the material comprises a coating arranged on the outside of the packaging, for example a protective varnish.
  • a blister varnish can be provided on the inside at least in places, preferably on the connecting surface of the two side surfaces.
  • the blister varnish can have sealing properties so that the connecting surfaces can be sealed to one another.
  • the method according to the invention makes it possible to pack goods in bag-shaped packaging made of paper or cardboard using a packaging machine suitable for film bags.
  • the Fig. 1 shows an embodiment of a bag-shaped packaging 1 according to the invention, which is formed by folding and gluing a paper or cardboard blank 100.
  • the material of the paper or cardboard blank 100 preferably has a grammage in the range of 200 g/m 2 to 300 g/m 2 , for example in the range of 220 g/m 2 to 260 g/m 2 , in particular in the range of 220 g/m 2 to 240 g/m 2 or in the range of 240 g/m 2 to 260 g/m 2 .
  • a blister or sealing varnish can be applied to the inside of the connecting areas, which is heated in a sealing device of the packaging machine so that the side surfaces 4 are connected in the connecting area 7.
