  • Patent number: 10582814
    Abstract: A dispenser for interfolded napkins includes a container having a supporting surface for supporting a stack of interfolded napkins. The supporting surface extends in a horizontal plane, and is surrounded by side walls extending in a vertical direction perpendicular to the supporting surface. The side walls define a dispensing opening opposite the supporting surface. At least one tab is arranged in the container for retaining the stack of napkins during withdrawal of a napkin from the stack. The tab is pivotably arranged in relation to the container between a holding position, in which the tab extends horizontally over at least a portion of the dispensing opening, and a refill position, in which the tab is directed away from the dispensing opening. The tab pivots about a living hinge. One or more stop surfaces limit an extent to which the tab is able to turn about the living hinge toward the dispensing mouth.

  • Patent number: 10264930
    Abstract: The present disclosure relates to a dispenser for interfolded napkins, including an inner container defining a dispensing opening, and an outer sleeve including a dispensing mouth. The outer sleeve forms at least one open end portion being arranged to receive the inner container, and the dispensing mouth forms an open end towards an open end portion of the sleeve. When the inner container is located in the outer sleeve, a supporting surface is biased towards the dispensing opening of the inner container and vertically movable inside the inner container between a lower position and an upper position, and, at least in a region adjacent the open end of the dispensing mouth, the outer contour of the upper ends of the side walls of the inner container deviates from the inner periphery of the sleeve, forming an access opening to the space between the upper position and the dispensing mouth.

  • Patent number: 7614150
    Abstract: Method and arrangement for providing a stator or rotor component that is intended during operation to conduct a gas flow. A first wall part (14, 15) is placed with its one edge bearing against the flat side of a second wall part (9, 10), extending in the radial direction of the component, in such a way that the first wall part extends in the circumferential direction of the component. The edge of the first wall part is then laser-welded to the second wall part from an, in the circumferential direction, opposite side of the second wall part in relation to the first wall part in such a way that the joined-together portions of the wall parts form a T-shaped joint.

  • Publication number: 20090180872
    Abstract: A gas turbine casing for enclosing a gas turbine component, such as a fan, a compressor, a combustion chamber or a turbine is provided. The casing includes a double wall structure having a first inner tube and a second outer tube, the first inner tube and the second outer tube extending around a geometric longitudinal axis, which is intended to basically coincide with a longitudinal geometric central axis of a gas turbine. The first inner tube and the second outer tube overlap one another when these are viewed in a radial direction, a gap being formed between the outer boundary surface of the first inner tube and the inner boundary surface of the second outer tube. The double wall structure furthermore has a plurality of stays which take the form of plates, which are spaced at an interval from one another and extend radially between the first inner tube and the second outer tube, and which stays connect the first inner tube and the second outer tube to one another.
