摘要:
The disclosure relates to a packaging container and a method of producing a packaging container for liquid contents. The packaging container has a casing produced from a web-shaped multilayer material and in the form of a sleeve, which, at one end, is connected to a bottom portion and at the other end is connected to a top portion produced from a blow molded thermoplastic material. The casing is formed by winding of the multilayer material into sleeve form and liquid-tight sealing of the material edges to a joint seam extending longitudinally of the sleeve, the top portion being manufactured in that thermoplastic material is extruded to form a hose which is blow molded into continuous top portions which are separated from one another and connected to the sleeve.

摘要:
A filling assembly for filling of a tube of packaging material having a seal starting at a first level, comprises a conduit arranged to lead liquid into the tube of packaging material below said first level and a passage arranged to eject gas through openings into the tube of packaging material below said first level. The filling assembly is characterized in that a gasket is arranged to provide a seal between said filling assembly and said tube of packaging material upstream said openings such that the overpressure P1 downstream the gasket may exceed an ambient pressure Pa upstream the gasket.

The disclosure relates to a packaging container and a method of producing a packaging container for liquid contents. The packaging container has a casing (2) produced from a web-shaped multilayer material and in the form of a sleeve, which, at one end, is connected to a bottom portion (4) and at the other end is connected to a top portion (3) produced from blow moulded thermoplastic material. The casing (2) is formed by winding of the multilayer material into sleeve form and liquid-tight sealing of the material edges to a joint seam (9) extending longitudinally of the sleeve, the top portion (3) being manufactured in that thermoplastic material is extruded to form a hose (15) which is blow moulded into continuous top portions which are separated from one another and connected to the sleeve.
