A paperboard packaging container includes a sealing arrangement comprising a lid and a sealing rim. The packaging container further includes a circumferential lid sealing member applied in the lid. The sealing rim forms a closed loop extending around the container opening. The sealing rim further comprises a first sealing surface arranged at an upper end edge of the sealing rim and is arranged to seal against a second sealing surface constituted by the circumferential lid sealing member when the lid is in a closed position. The sealing arrangement furthermore includes a frame structure forming a closed loop extending around a periphery of the container opening and is connected to the sealing rim. The lid is connected to the frame structure by a hinge member and a locking arrangement.
A paperboard packaging container, said packaging container comprising a container body said container body comprising a container wall extending from a container bottom to a container opening in a height direction of said packaging container, and a sealing arrangement comprising a lid and a sealing rim, said lid comprising a top portion and a side wall portion, said top portion having an outer lid surface and an inner lid surface opposite to said outer lid surface, said packaging container comprising a circumferential lid sealing member applied in said lid against an inner lid support surface, said sealing rim forming a closed loop extending around said container opening and being attached to an inner surface of said container wall at said container opening and comprising a first sealing surface arranged at an upper end edge of said sealing rim and being arranged to seal against a second sealing surface constituted by said circumferential lid sealing member when said lid is in a closed position, said sealing arrangement further comprising a frame structure, said frame structure forming a closed loop extending around a periphery of said container opening and being connected to said sealing rim, said lid being connected to said frame structure by a hinge member arranged at a first part of said frame structure and a locking arrangement being arranged on said frame structure at a second part of said frame structure, which is located opposite said first part of said frame structure, said locking arrangement comprising interengaging locking elements, wherein a first interengaging locking element is arranged in or on said outer lid surface of said lid top portion and a second interegaging locking element is arranged on or in a locking flap arranged on said frame structure and being hingedly connected to said frame structure by means of a hinge formed integrally with, or connected to, said frame structure, said circumferential lid sealing member being made from a polymeric foam having a closed-cell structure, has a no-load thickness to of from 1.5 to 5 mm and a density of from 10 to 75 kg/m3 and in that a distance d1 is defined between said first sealing surface of said sealing rim and said inner lid support surface when said lid is in a closed position and wherein t0>d1 and wherein said lid sealing member is applied in said lid with a lateral compression against said side wall portion such that the lid sealing member bulges toward the first sealing surface and a compression force of the first sealing surface against the second sealing surface of the lid sealing member when the lid is in the closed position increases.
A lid component comprising a lid and frame structure, said lid comprising a top portion and a side wall portion, said top portion having an outer lid surface and an inner lid surface opposite to said outer lid surface, said packaging container comprising a circumferential lid sealing member applied in said lid against an inner lid support surface, said frame structure forming a closed loop and said lid being connected to said frame structure by a hinge member arranged at a first part of said frame structure, and a locking arrangement being arranged on said frame structure at a second part of said frame structure which is located opposite said first part of said frame structure, said locking arrangement comprising interengaging locking elements, wherein a first interengaging locking element is arranged in or on said outer lid surface of said lid top portion and a second interengaging locking element is arranged in or on a locking flap arranged on said frame structure and being hingedly connected to said frame structure by means of a hinge formed integrally with, or connected to, said frame structure, wherein said circumferential lid sealing member is made from a polymeric foam having a closed-cell structure, has a no-load thickness of from 1.5 to 5 mm and a density of from 10 to 75 kg/m3 and wherein said lid sealing member is applied in said lid with a lateral compression against said side wall portion;
