SEALING ARRANGEMENT FOR PACKAGING CONTAINER

The present disclosure relates to a paperboard packaging container (1) comprising a container body (2) and a sealing arrangement comprising a lid (9) and a sealing rim (10). The packaging container (1) comprises a circumferential lid sealing member (15) applied in the lid (9) against an inner lid support surface (14a). The sealing rim (10) forms a closed loop extending around a container opening (5) and is attached to an inner surface (6) of the container wall (3) at the container opening (5). The sealing rim (10) further comprises a first sealing surface (16) arranged at an upper end edge of the sealing rim (10) and is arranged to seal against a second sealing surface (17) constituted by the circumferential lid sealing member (15) when the lid is in a closed position. The lid (9) is connected to a frame structure (18) by a hinge member (19), and the frame structure (18) is connected to the sealing rim (10). The circumferential sealing member (15) is made from a polymer foam having a closed-cell structure, has a no-load thickness t0 of from 1.5 mm to 5 mm and a density of from 10 to 75 kg/m3. A distance d1 is defined between the first sealing surface of the sealing rim and the inner support surface (14a) of the lid when the lid is in a closed position, and wherein the distance d1 is smaller than the no-load thickness t0 of the circumferential lid sealing member, i.e. t0>d1. The lid sealing disc (15) is applied in the lid (9) with a lateral compression against a side wall portion (12) of the lid such that lateral tension through the lid sealing disc (15) is created.
