Abstract: A packaging container (1, 201) comprising a container body (2, 202) having a bottom end (4, 204) and a top end (5, 205) and a tubular container wall (3, 203) extending between the bottom end and the top end. The packaging container(1, 201) is closed at the bottom end (4, 204) by a base disc (9, 209) which is attached by welding to the inner surface (7, 207) of the container body (2, 202) at the bottom end (4, 204) of the container body. The container body comprises a laminate body sheet material (12) comprising a carton layer (12a), a metallic foil layer (12b) and an inner thermoplastic polymeric layer (12c). A top end closure comprising an openable and reclosable lid (16, 216) is arranged at the top end of the packaging container (1).

Abstract: A method of forming a paperboard packaging container from a rectangular body blank is disclosed, the method including the following steps: a) providing a rectangular body blank made from a laminate sheet material; b) forming a tubular container body from the rectangular body blank, the container body having a first end with a first body opening and a second end with a second body opening; c) sealing together the first and the second side edge in a but-to-but seal using a sealing strip having a sealing strip width; d) presenting the tubular container body to a crease line forming station; e) closing the second body opening by pressing a paperboard disc into the second body opening; f) forming a curled second edge by folding or rolling the second end of the container body wall inwardly; g) filling the packaging container with bulk solids; and h) closing the first body opening.

Abstract: A sealing disc for sealing an inner compartment in a packaging container, said sealing disc having a first surface and a second surface and being delimited by a sealing disc outer edge, the sealing disc comprising a peripheral edge portion surrounding at least two fully or partly removable tear-open parts, each fully or partly removable tear-open part being arranged to be fully or partly separated from said peripheral edge portion along a contour line. A packaging container comprising the sealing disc is also disclosed.

Abstract: A method for manufacturing and filling a composite can (201), the method comprising: —forming a tubular body (203) by bending a body blank (16) and bringing two opposing edges of the body blank (16) together in an end-to-end join; —sealing the join by welding a sealing strip (214) over the join, thereby forming an intermediate can (403; 503); —sealing a top opening (211) by attaching a top sealing member (227) across the top opening (211); —applying a top rim (223) to the intermediate can (403; 503) by welding an inserted part of the top rim (223) to the inner surface of the tubular body (203); —turning the intermediate can (403; 503) upside-down and placing the intermediate can (403; 503) on a conveyor (2a) with the top rim (223) resting on the conveyor (2a); filling the intermediate can (403; 503) through the bottom opening (213); —sealing the bottom opening (213) of the tubular body (203) by attaching a bottom sealing member (215) across the bottom opening (213); —turning the intermediate can (403; 503) to

Abstract: A composite container (300) comprising a tubular body (301), the tubular body (301) having an inside surface (306) and an outside surface (307) and a container opening (337) at a top end (338) of the tubular body (301), the tubular body (301) being made from a laminate sheet material (8) comprising a carton layer (10, 310) and an inside polymeric layer (11, 311), the inside polymeric layer (311) being arranged at an inside surface (306) of the carton layer (10, 310), the composite container (300) comprising a top rim (339) surrounding the container opening (337), the top rim (339) being attached to a top end portion (340) of the tubular body (301) at the top end (338) of the tubular body (301), and a lid (342) for opening and closing the composite container (300).

Abstract: The present disclosure pertains to a laminate membrane for sealing an inner compartment in a packaging container comprising a top member and a bottom member. The top and bottom members are laminated sheet materials. The top member has a thickness, a top member first surface and a top member second surface facing the bottom member. The bottom member has a bottom member first surface facing the top member second surface and a bottom member second surface. The laminate membrane is provided with a valve for allowing gas in the inner compartment of the packaging container to exit therefrom. The valve has a valve outer edge and is arranged on the bottom member first surface. The valve is arranged within an opening in the top member such that an opening edge encircles the valve. A surface area of the opening is greater than a surface area of the valve.

Abstract: The present disclosure relates to a paperboard packaging container comprising a sealing arrangement comprising a lid and a sealing rim. The packaging container comprises 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 comprises a frame structure forming a closed loop extending around a periphery of said 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.
