The first expansion tool (9) and the second expansion tool (10) are movable in relation to each other in the axial direction (A). The first expansion tool (9) comprises at least one inclined plane surface (15), which is arranged with a first end (15') closer to the base plate (8) than a second end (15'') in the axial direction (A). Each inclined plane surface (15) of the first expansion tool (9) is inclined away from the plunger axis (a1) from the first end (15') of the inclined plane surface (15) to the second end (15'') of the inclined plane surface (15). The second expansion tool (10) comprises at least one inclined plane surface (16) corresponding to the at least one inclined plane surface (15) on the first expansion tool (9). Each inclined plane surface (16) on the second expansion tool (10) has a first end (16') being arranged further away from the base plate (8) than a second end (16'') in the axial direction (A). Each inclined plane surface (16) on the second expansion tool (10) is inclined towards the plunger axis (a1) from the first end (16') of the inclined plane surface (16) to the second end (16'') of the inclined plane surface (16). Each inclined plane surface (15) on the first expansion tool (9) contacts and applies pressure to the corresponding inclined plane surface (16) of the second expansion tool (10) when the expansible press plunger (2) is in the radially expanded state. An attachment unit for attaching a container sealing element to a container body and a method for attaching a container sealing element to a container body are also disclosed.
The present disclosure relates to a composite paperboard container (1) for bulk solids, the composite paperboard container comprising a tubular body (2) being closed at a bottom end (3) over a container bottom opening (4) opposite a container top opening (5). The composite container comprises a rim (9) surrounding the container top opening and/or the bottom opening. The rim is attached with a first connecting portion (11) of the rim to an end portion (10) of the tubular body. The rim is a molded rim comprising pulp fiber.The rim is connected to the tubular body by means of a first adhesive layer (14), the first adhesive layer comprises or consists of thermoplastic adhesive in an amount of from 0.1 mg per 10 mm of the container opening perimeter (pt,pb) at the end portion of the tubular body. The present disclosure furthermore relates to a method of producing a composite paperboard container.

The present disclosure relates to a composite paperboard container for bulk solids. The composite paperboard container (1) comprising a tubular body (2) being closed at a bottom end (3) over a container bottom opening (4) opposite a container top opening (5) at a top end (6) of the tubular body (2). The tubular body (2) has an inner surface (7) facing towards an interior of the container body (2) and an outer surface (8) facing away from the interior of the container body (2). The tubular body (2) extends in a longitudinal direction (L). The composite container (1) comprises a rim (9) surrounding the container top opening (5) and/or the container bottom opening (4). The rim (9) is attached at a connecting portion (11) of the rim (9) to an end portion (10) of the tubular body (2) along an end edge (12) of the tubular body (2). The connecting portion (11) of the rim (9) has a distal edge (11a). The tubular body (2) is made from a laminate sheet material (8) comprising a carton substrate layer and a thermoplastic welding layer (14). The rim (9) is a molded rim (9) comprising pulp fibers, such as softwood pulp fiber. The tubular body (2) is connected by welding to the connecting portion (11) of the rim (9) and the distal edge (11a) of the rim is located at a distance from the end edge (12) of the tubular body of at distance from the end edge (12) of the tubular body of at least 4 mm, optionally within the range of from 4 mm to 50 mm, as seen in the longitudinal direction (L) of the tubular body (2). The present disclosure also relates to a method of producing a composite paperboard container.

The present disclosure relates to methods of producing a packaging container for bulk solids. The packaging container has an inner compailnient and a transport closure closing the inner compailnient, the transport closure being provided with a pressure relief valve, the method includes the steps of forming a tubular container body having an upper body opening; presenting the container body to an upper body opening sealing station comprising a plunger piston comprising a bottom plate, the bottom plate having a through hole; closing the upper body opening by pressing the transport closure into the upper body opening such that a pressure above an ambient pressure is produced within the tubular container body, allowing gas to exit the valve and the valve to be pre- conditioned; and attaching the transport closure to the container body wall.
