Abstract: A flip-top closure for composite and cardboard packaging, which permits the automatic opening of a package by flipping open the lid of the closure, includes a frame base element, which is designed to be welded by its level underside to composite or card-board packaging, and has a continuous peripheral overhang that protrudes upwards in order to form a pouring neck with an interior opening. A cover that flips open and closes is fixed to the base element. A guide, or tongue, element is pivotally mounted on the base element extends over the interior expanse of the overhang and friction-fit elements act between the tongue, or guide, element and the cover to pivot the tongue downwardly by force when the cover is flipped open for tearing and pivoting away a piece of the packaging lying below the tongue or guide element.

Abstract: The advertising support consists of a stowage space (3) with an opening top and an inflatable advertising support (11) stowed inside it which, when the top of the stowage space (3) is opened, can be inflated upwards from it. In the stowage space (3) there is a scissors structure (7,17) which can be erected by a motor and forms a stable-sided parallelogram which is free-standing and, in the expanded position, extends along the internal height of the inflated advertising support (11). It ensures that, when the scissors structure (7,17) is retracted and the advertising support (11) is deflated at the same time, said advertising support (11) is substantially folded down onto its original base area and prevented from tipping sideways by the lateral stability of the scissors structure.

Abstract: A weather protective roofing structure for small aircraft comprising a plurality of hemispherical bars which are supported in a rotatable manner around a common axis, which bars are attached to and covered with a plurality of covering material segments forming a hemispherical cover. The hemispherical bars are rotatable around the common axis by means of a tackle apparatus and an electrical winch during assembly of the roofing structure to form an enclosure, and during disassembly and folding of the hemispherical cover. Assembly and disassembly are facilitated by means of two torsion springs provided at the hinge assemblies and attached to the outermost bar.
