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.

Flexible membrane with valve

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.

The present disclosure relates to a positioning unit for positioning a container element in a container body, comprising a base plate of a rigid material, and a plunger skirt of a resiliently deformable material. A footprint surface of the base plate has a circumferential edge with a side edge portion comprising an inwardly curved segment. The plunger skirt is transformable between an unexpanded state and an expanded state by relative movement in relation to the base plate. The disclosure further relates to an attachment unit for attaching a container element to a container body and to an apparatus for attaching container elements to container bodies in a flow of containers. In addition, the disclosure relates to a method of positioning a container element in a container body by means of the positioning unit.

Positioning unit and attachment unit for container element

A lid component for a paperboard packaging container, the lid component comprising a lid part and a connecting part, the lid part comprising a top portion and a side wall portion, the top portion having an outer lid surface, an inner lid surface opposite to the outer lid surface, and a peripheral edge surrounding the outer lid surface; and the connecting part comprising an upper portion and a lower portion and having a lower edge surface. Stacking members are arranged on the outer lid surface and comprise a lid component stacking step and a container stacking step, the lid component stacking step being arranged laterally outboard and below the container stacking step. The lower portion of the connecting part is adapted to be supported by the lid component stacking step. A lid component comprising a locking arrangement and paperboard packaging container comprising a lid component are also disclosed.

The present disclosure relates to a paperboard sealing disc for use in a packaging container, comprising a peripheral edge portion surrounding a tear-open part having a push-tab and a pull-away part. The tear-open part is delimited from the peripheral edge portion by a first cutting line in the first side and by a second cutting line in the second side. Said first cutting line being provided at a distance dfrom said sealing disc outer edge, and said second cutting line being provided at a distance dfrom said sealing disc outer edge. The push-tab is at least partly delimited from the pull-away part by a folding line. At the push-tab d&#x3e;dand at the pull-away part d&#x3e;d. Furthermore, dat said push-tab is substantially the same as dat said pull-away part and dat said push-tab is substantially the same as dat said pull-away part.

Push-and-pull sealing disc for packaging container

The present invention provides a packaging container for bulk solids. The container comprises a container body having a container wall extending from a container bottom to a container opening in a height direction of the container. The container wall and the container bottom delimit an inner space in the container, and a first peelable or tearable sealing membrane being attached to an inner surface of the container wall forms a roof over a first inner compartment in the inner space. A second peelable or tearable sealing membrane is applied between the first peelable or tearable sealing membrane and an edge of the container opening and is attached to the inner surface of the container wall. The first peelable or tearable sealing membrane forms a floor of a second inner compartment in the inner space and the second peelable or tearable sealing membrane forms a roof over the second inner compartment.

Method of making packaging container for bulk solids

A method of producing and filling a paperboard packaging container with bulk solids material comprising forming a tubular container body, closing an upper body opening of the tubular container body, filling bulk solids into the container body a bottom body opening of the tubular containing body, closing the bottom body opening, and turning container body such that an upper end is directed upwards in a vertical direction, thereby allowing improved control of the pressure within the packaging container.

Method of producing and filling a packaging container

A method of producing and filling a paperboard packaging container with pulverulent bulk solids includes forming a tubular container body from a paperboard sheet, the body having upper and lower body openings and a container wall extending between the upper and lower body openings and having inner and outer surfaces; closing the upper body opening with a sealing membrane attached to the inner surface; providing an upper reinforcing rim; inserting at least a lower part of the upper reinforcing rim into the tubular container body at the upper body opening; forming a weld seal between the inner surface and the inserted part of the upper reinforcing rim; presenting the body to a filling station with the bottom body opening of the container body directed upward in a vertical direction; filling pulverulent material into the body through the upwardly directed bottom body opening; and closing the bottom body opening.

A paperboard packaging container for bulk solids includes a container body having a container wall extending from a container bottom edge to a container body opening and having an inner surface facing an inner compartment in the packaging container, and a lid for closing the container body opening. An upper reinforcing rim is applied at the container body opening and extends along the opening edge, defining a perimeter of a container access opening and is joined to the inner surface of the container wall by means of a weld seal which extends around the container body opening and has an upper edge including a first abutment surface arranged to abut against a second abutment surface on an inner lid surface with the lid in a closed position on the container access opening and form a tight seal between the rim and the lid with the lid in the closed position.

Packaging container with rim and lid

A paperboard packaging container for bulk solids includes a container body formed by a container wall having wall portions, and a container bottom. The wall portions are connected by corner portions and each wall portion extends in a height direction from a lower end edge at the container bottom to an upper end edge at a container opening, the height direction being perpendicular to a cross direction of the container. An upper reinforcing rim is applied to the container opening. Each of the upper and lower end edge of the container wall has end edge portions corresponding to the wall portions. At least one edge portion has an outwardly curved shape and a radius of curvature larger than a radius of curvature of each corner edge portion, the at least one end edge portion bulges outwardly with a radius of curvature of 200-700 mm, preferably 300-600 mm, more preferably 400-500 mm.
