Paperboard packaging container and lid

A method of producing a paperboard packaging container, the method comprising:

• a) bending a paperboard sheet material into a tube having a longitudinal direction, a radial direction perpendicular to said longitudinal direction, and a circumferential direction and closing said tube in said longitudinal direction by joining overlapping or abutting side edges of said paperboard material, said closed tube having a top end and a bottom end and comprising a container body portion and a lid collar portion, said lid collar portion being arranged at said top end and being delimited from said body portion by a dividing line extending in said circumferential direction between said body portion and said lid collar portion;
• b) imparting a predetermined cross-sectional shape to said tube;
• c) closing said tube at said top end by pressing a transport closure into said tube at said top end or at said bottom end, said transport closure having a transport closure peripheral flange being flexed towards said top end or towards said bottom end, said transport closure being a partially removable closure;
• d) attaching said transport closure peripheral flange to an inner surface of said container body portion at said top end of said tube;
• e) pressing a paperboard top disc into said tube at said top end, said top disc having a peripheral flange being flexed towards said top end in said longitudinal direction, said flexed peripheral flange extending in said longitudinal direction across said dividing line with an attachment portion positioned at said lid collar portion and a plug-in portion positioned at said container body portion;
• f) attaching said attachment portion of said peripheral flange of said paperboard top disc to an inner surface of said lid collar portion of said tube;
• g) forming a locking arrangement by providing said container body portion with a first locking element and providing said plug-in portion with a second locking element, said first and second locking elements being mating locking elements comprising a protrusion and a recess, said mating locking elements being formed by physically deforming said paperboard material in said container body portion and said plug-in portion in said radial direction;
• h) arranging a slit or weakening means extending along from 10-100% of said dividing line, said slit or weakening means being arranged along said dividing line before or after forming said tube.
