A package material may include one or more layers of plastic laminate, a first side, a second side and a penetration area. A weakening line may extend from the penetration area and may provide an opening area in the package material. The package material may include a plastic opening device, with a first and second portion attached to the first and second side, respectively, and a material bridge penetrating through the penetration area. The second portion may cover at least partly the penetration area and may include a guiding portion extending from the penetration area adjacent to the at least one weakening line as to facilitate rupturing substantially along the at least one weakening line.

A package material comprises a multilayer material structure with layers of plastic laminate, a penetration area (5, 62, 250) and two weakening lines (10) creating an area in between. The package material comprises an opening device with a first (3, 63, 220) and second (2, 222) portion attached to respective sides and a material bridge (31, 65, 231) penetrating the penetration area and connecting the first portion to the second portion. The second portion at least partly covers the penetration area and comprising a rupture section (13, 213) covering at least partly the two weakening lines. The rupture section comprises one or more rupture recesses (14, 141-145, 232) disposed over or adjacent to the weakening lines for guiding a rupture of the multilayer material structure along the weakening lines.

The present invention is directed to a packaging (1) comprising: a body (2) defining an interior volume (6) for carrying a flowable product, andan opening element (4) comprising an opening part (4.0) which is arranged inside the interior volume (6). The body (2) is configured such that, when a predetermined external force (F) is exerted on an activation section (8) of the body (2), the activation section (8) is displaced relative to the interior volume (6) so as to activate the opening element (4) until the opening part (4.0) creates an opening extending in an openable section (12) of the body (2) and allowing the flowable product to flow out of the interior volume (6).

Unlike other sealing devices which are internal to a bag and adhered to the bag by heat or glue the current invention is external to the bag, is not adhered to the bag by heat or glue, is free to be moved up or down the bag to remove excess air, is reusable, and can be used on one type of a bag in one instant, removed, and be used on another type of bag. Furthermore, on current sealing devices if anything comes in-between the male and female seals which go directly into each other it renders the seal ineffective, but the current invention is not disturbed at all, and in fact the bag type container becomes part of the seal.
