  • Publication number: 20210292061
    Abstract: A cap and neck assembly for closing an upper end of a package (10) is provided. The neck (20) is formed by a tubular member (110) being provided with external threads (22), and an upper tubular portion (120) extending from the tubular member (110) and being releasably attached to a membrane (150) closing an upper end of said upper portion (120). The cap has a lower portion the threads (22) of the neck (20), and an upper portion (33) being provided with at least one cutting element (50) configured to separate the membrane (150) from the neck (20). When the cap (30) is threaded onto the neck (20) to its axial end position for the first time prior to separating the membrane (150) from the neck (20), the axial distance between a cutting edge (54) of the cutting element (50) and the membrane flange (170) is less than 1 mm.

  • Patent number: 8154374
    Abstract: A transformer winding having a conductor wound in a plurality of turns is disclosed, wherein the transformer winding includes a reinforcing part arranged at a winding transition in a manner so that the reinforcing part covers more than 180 degrees of the conductor circumference, whereby the bending strength of the conductor at the location of the reinforcing part is increased. The resistibility of the transformer winding against bending stress is hence improved.
