Packaging container for bulk solids

Abstract

The present invention provides a packaging container for bulk solids. The container comprises a container body having a container wall extending from a container bottom to a container opening in a height direction of the container. The container wall and the container bottom delimit an inner space in the container, and a first peelable or tearable sealing membrane being attached to an inner surface of the container wall forms a roof over a first inner compartment in the inner space. A second peelable or tearable sealing membrane is applied between the first peelable or tearable sealing membrane and an edge of the container opening and is attached to the inner surface of the container wall. The first peelable or tearable sealing membrane forms a floor of a second inner compartment in the inner space and the second peelable or tearable sealing membrane forms a roof over the second inner compartment.

1 . A packaging container for bulk solids, said packaging container comprising:
 a container body having a container wall extending from a container bottom to a container opening in a height direction of said container, said container wall having wall portions and corner portions, said container wall and said container bottom delimiting an inner space in said container,   a first sealing membrane being attached to an inner surface of said container wall and forming a roof over a first inner compartment in said inner space;   a second sealing membrane being applied between said first sealing membrane and an edge of said container opening and being attached to said inner surface of said container wall, said first sealing membrane forming a floor of a second inner compartment in said inner space and said second sealing membrane forming a roof over said second inner compartment,   wherein said first sealing membrane and said second sealing membrane are peelable or tearable sealing membranes which each comprise a gripping member,   said corner portions are curved corner portions, and   a rim is applied to said edge of said container opening and is affixed to said container body along said edge of said container opening and an openable and closable lid is arranged to engage with said rim to form a closure on said packaging container.   
     
     
         2 . The packaging container according to  claim 1 , wherein said container comprises three or more sealing membranes dividing said inner space into three or more inner compartments, such as 3-10 inner compartments wherein said inner compartments being in addition to said first inner compartment are delimited in said height direction of said container by peelable or tearable sealing membranes and wherein an uppermost peelable or tearable sealing membrane being located closest to said container opening forms a roof over a corresponding uppermost inner compartment being located closest to said container opening. 
     
     
         3 . The packaging container according to  claim 1 , wherein said sealing membranes are arranged equidistantly from each other in said height direction of said packaging container, thus forming equally sized inner compartments. 
     
     
         4 . The packaging container according to  claim 1 , wherein the distance between at least two of said sealing membranes in said height direction of said packaging container is different from the distance between the remaining sealing membranes, thus forming at least two differently sized inner compartments. 
     
     
         5 . The packaging container according to  claim 1 , wherein at least one of said peelable or tearable sealing membranes is gastight and is applied to said inner surface of said container wall by a gastight seal. 
     
     
         6 . The packaging container according to  claim 1 , wherein said peelable or tearable sealing membrane is a peelable sealing membrane. 
     
     
         7 . The packaging container according to  claim 1 , wherein said container wall portions consist of a front wall portion, a rear wall portion and two side wall portions, said wall portions being connected at container body edge portions. 
     
     
         8 . The packaging container according to  claim 7 , wherein said container body has a cuboid or generally cuboid shape. 
     
     
         9 . The packaging container according to  claim 1 , wherein said curved corner portions have a radius of curvature of from 15-100 mm. 
     
     
         10 . The packaging container according to  claim 1 , wherein said openable and closable lid, is a hinged lid. 
     
     
         11 . The packaging container according to  claim 1 , wherein said packaging container further comprises an openable and closable lid arranged to cover said container bottom. 
     
     
         12 . The packaging container according to  claim 11 , wherein a non-removable inner sealing membrane is arranged between two peelable or tearable sealing membranes. 
     
     
         13 . The packaging container according to  claim 1 , wherein said bulk solid within said first inner compartment is different from a bulk solid within at least said second inner compartment. 
     
     
         14 . The packaging container according to  claim 1 , wherein said container is a container for tobacco.
