A method of producing and filling a paperboard packaging container with pulverulent material wherein the method comprises the steps of: a) forming a tubular container body from a paperboard sheet, said container body having an upper end with an upper body opening and a bottom end with a bottom body opening (6") and a container body wall extending in a height direction of said packaging container between said upper body opening and said bottom body opening (6"), said container body wall having an inner surface and an outer surface, an upper end edge and a bottom end edge; b) closing said upper body opening with a sealing membrane which is attached to said inner surface of said container body wall; c) providing an upper reinforcing rim in the form of a closed loop having a main extension in a loop plane, said upper reinforcing rim having an outer contour and an inner contour and having a height in a height direction perpendicular to said loop plane with an upper rim part and a lower rim part in said height direction of said upper reinforcing rim, characterized in that the method further comprises the steps of: d) inserting said lower rim part of said upper reinforcing rim and optionally also said upper rim part of said upper reinforcing rim into said tubular container body at said upper body opening with an upper end edge of said upper reinforcing rim being outside of said container body or flush with said upper end edge of said container wall; e) forming a weld seal between said inner surface of said container wall and said inserted part of said upper reinforcing rim; f) presenting said container body to a filling station with said bottom body opening (6") of said container body directed upward in a vertical direction; and: g) filling pulverulent material into said container body through said upwardly directed bottom body opening (6"); and h) closing said bottom body opening (6"); i) applying a lid at said upper end of said container body after closing said bottom body opening in step h); wherein steps a) to f) are performed before steps g) to i) and step b) is performed between steps a) and c), or is performed between steps e) and f). a) forming a tubular container body from a paperboard sheet, said container body having an upper end with an upper body opening and a bottom end with a bottom body opening (6") and a container body wall extending in a height direction of said packaging container between said upper body opening and said bottom body opening (6"), said container body wall having an inner surface and an outer surface, an upper end edge and a bottom end edge; b) closing said upper body opening with a sealing membrane which is attached to said inner surface of said container body wall; c) providing an upper reinforcing rim in the form of a closed loop having a main extension in a loop plane, said upper reinforcing rim having an outer contour and an inner contour and having a height in a height direction perpendicular to said loop plane with an upper rim part and a lower rim part in said height direction of said upper reinforcing rim, characterized in that the method further comprises the steps of: d) inserting said lower rim part of said upper reinforcing rim and optionally also said upper rim part of said upper reinforcing rim into said tubular container body at said upper body opening with an upper end edge of said upper reinforcing rim being outside of said container body or flush with said upper end edge of said container wall; e) forming a weld seal between said inner surface of said container wall and said inserted part of said upper reinforcing rim; f) presenting said container body to a filling station with said bottom body opening (6") of said container body directed upward in a vertical direction; and: g) filling pulverulent material into said container body through said upwardly directed bottom body opening (6"); and h) closing said bottom body opening (6"); i) applying a lid at said upper end of said container body after closing said bottom body opening in step h);
