  • Patent number: 11787615
    Abstract: The invention relates to a bag (3) having a filling space for bulk material, which filling space is delimited by a lower base (4), a circumferential wall (6), and an upper filling space closure (8) facing away from the lower base (4). The bag has at least one tear-open strip (10) for exposing an opening area (12) of the bag (2), which is delimited by an upper weakening line (14) and a lower weakening line (16), wherein both weakening lines (14, 16) extent parallel to the upper filling space closure (8), and the upper weakening line (14) is positioned between the upper filling space closure (8) and the lower weakening line (16). The bag (2) has a longitudinal seam (18) extending transversely with respect to the upper filling space closure (8). The upper and the lower weakening line (14, 16) begin in the area of the longitudinal seam (18).

  • Patent number: 10759567
    Abstract: Disclosed is a flexible packaging container, in particular a plastic film pouch or bag for bulk goods, comprising a front wall (2) and a rear wall (3) as well as a holding space (15) between said walls (2, 3) for goods to be stored; the walls (2, 3) are made at least in part of a film material; the flexible packaging container further comprising an intermediate space (14) which is formed by an inner ply (4) and is separated from the holding space (15) by said inner ply (4); the holding space (15) can be evacuated into the intermediate space (14) via at least one holding space evacuation hole (7) in the inner ply (4), and the intermediate space (14) can be evacuated out of the packaging container (1) via at least one additional evacuation hole (11) that interrupts a transverse seam; the front wall (2) does not comprise any of the longitudinal seam (12) that seals the packaging container (1) in the peripheral direction; the inner ply (4) is formed by a strip (4) which is located on a side of the front wall (2)

  • Patent number: 7805917
    Abstract: The invention pertains to a combine head with a frame to which a transverse conveyor spiral is secured that extends transversely with respect to the forward direction of the combine head, where several conveyor belt assemblies are pre-arranged at this transverse conveyor spiral in a laterally sequential manner in the forward direction and are equipped with conveyor belts, and in the harvesting mode of operation, convey material to be harvested rearward to the transverse conveyor spiral, which in turn conveys it transversely with respect to the forward direction and toward the middle of the combine head, wherein a cover is present between adjacent conveyor belt assemblies in order to seal off the inner zones of the conveyor belt assemblies.
