Abstract:
The invention relates to a closure device (10) for re-closing an opening on a packaging container, said opening having been initially opened within an opening area. The packaging container is provided with a first fold axis (14). The closure device (10) comprises at least a first closure device part (16) arranged on a first side of the first fold axis (14) and at least a second closure device part (18) arranged on a second side of the first fold axis (14). The first closure device part (16) is arranged between the opening area and the first fold axis (14). Further, the first and second closure device parts (16, 18) are provided with mutual lockable members such that the first and second closure device parts (16, 18) may be releasably locked to each other upon folding the packaging container along the first fold axis (14) thereby re-closing the opening in the packaging container. The invention further relates to a packaging container with a closure device as well as a method of manufacturing the packaging container.
Abstract:
The present invention relates to an opening and closure device 10 on a packaging container 100 for liquid or semi-liquid food. The packaging container has a fold line 16 and an opening line 13 intersecting in an intersection point, thereby dividing the opening line into a first opening line portion 13a and a second opening line portion 13b. The opening and closure device comprises an opening device 12 adapted for facilitating rupture of the packaging material along the opening line 13, and a closure device 14 adapted for re-closing the packaging container after opening along the opening line 13. The invention also comprises a packaging container with an opening and closure device and a method of manufacturing said packaging container.

Abstract:
A filling assembly (100) for filling of a tube (28) of packaging material having a seal starting at a first level, comprises a conduct (106) arranged to lead liquid into the tube 28 of packaging material below said first level and a passage (110) arranged to eject gas through openings (118) into the tube (28) of packaging material below said first level. The filling assembly is characterized in that a gasket (120) is arranged to provide a seal between said filling assembly and said tube (28) of packaging material upstream said openings such that the overpressure P 1 downstream the gasket may exceed an ambient pressure P a upstream the gasket
