1. A paperboard packaging container for bulk solids, said container comprising:
a tubular paperboard container body, a container bottom, and a paperboard container lid,
said container body extending in a longitudinal direction of said container from a bottom end of said container body to a container opening, said container body comprising a container body abutment edge at said container opening, said container body having an inner surface facing towards an inner compartment in said packaging container and an outer surface facing away from said inner compartment,
said container lid comprising a lid collar having a lid abutment edge adapted for abutting against said container body abutment edge when said container lid is in a closed position, and a plug-in portion, said plug-in portion having a side surface, extending in said longitudinal direction and facing said inner surface of said container body when said container lid is in said closed position, and a main surface extending along a bottom of said container lid, said main surface of said plug-in portion being located at a distance from said container body abutment edge when said container lid is in said closed position, wherein a peripheral flange of the container lid extends from the main portion of the plug-in portion and the side surface of the plug-in portion comprises at least a portion of the peripheral flange,
wherein said lid collar is made of the same material as the container body and said lid collar is delimited from said container body by a slit or by weakening means for allowing said lid collar to be fully or partially separated from said container body at said abutment edges, and wherein the lid collar is folded over the peripheral flange so that the lid collar is in face-to-face contact with an interior surface of the peripheral flange and with an exterior surface of the peripheral flange, said packaging container being provided with a locking arrangement for retaining said container lid in said closed position,
a hinge provided between the container lid and the container body so that the container lid is opened by pivoting the container lid about the hinge,
a reinforcement of the container opening is provided by at least one of:
(i) a partially removable transport closure being attached to said inner surface of said container body and forming a roof over said inner compartment; or
(ii) by said container body being formed from a multi-ply paperboard material including at least one or more reinforcing non-cellulosic layer; and
wherein said locking arrangement comprises a first locking element in the form of an elongated continuous recess, provided on said inner surface of said container body, and a second locking element in the form of an elongated continuous protrusion provided on said side surface of said plug-in portion, said first and second locking elements being mating locking elements formed by simultaneous deformation of the inner surface of the container body and the side surface of the plug-in portion of the lid, wherein said first locking element and said second locking element are arranged such that when said container lid is in said closed position said protrusion is in engagement with said recess, and the first locking element and the second locking element are spaced upwardly in the longitudinal direction from the main surface of the plug-in portion along respective perimeters of the first locking element and the second locking element and are spaced downwardly in the longitudinal direction from the lid collar along the respective perimeters of the first locking element and the second locking element.
