Abstract (en)

[origin: WO2018009130A1] The present disclosure relates to a paperboard sealing disc (10) for use in a paperboard packaging container (1 ) for bulk solids. The packaging container (1) comprises a container body (2) with an upper end (4) with an upper body opening (5') and a bottom end (6) with a bottom body opening (5"), a container wall (3) extending between the upper end (4) and the bottom end (6) in a longitudinal direction (L). The container wall (3) has an inner surface (7) facing towards an inner compartment (9) in the packaging container (1 ) and an outer surface (8) facing away from the inner compartment (9). The sealing disc (10) is intended for sealing the upper body opening (5') or the bottom body opening (5"). The sealing disc (10) comprises a sealing disc border (11) surrounding a sealing disc base portion (12), wherein the border (11) is delimited from the disc base portion (12) by a sealing disc inner folding edge (31). The sealing disc border (11) is intended to be flexed at the inner folding edge (31) to project out of a main plane of the sealing disc (10) and to be aligned with and sealed to the inner surface (7) of the container wall (3). The sealing disc (10) comprises one or more distance element(s) (14) arranged in the sealing disc border (11) and facing the inner surface (7) of the container wall (3), the distance element(s) (14) having a height (H), as measured from the surface of the sealing disc border (11).
