  • Publication number: 20250129831
    Abstract: A spring carrier for receiving, retaining, and discharging of a coil spring in a manufacturing assembly process includes an elongate hollow body defining an inner cavity to receive the coil spring and an opening at a proximal first end of the hollow body for the insertion of the coil spring into the inner cavity and extraction of the coil spring from the inner cavity. A deflectable member is located proximate to the first proximal end and includes a retaining portion that retains the coil spring when the coil spring is located within the inner cavity. The deflectable member is movable between a first unbiased position, where the retaining portion extends into the inner cavity to retain the coil spring within the inner cavity, and a second biased position, where the retaining portion is disposed outwardly to allow the coil spring to be extracted from the inner cavity through the opening.

  • Publication number: 20250035261
    Abstract: A device for lubricating a surface of a tubular element includes a shaft portion having a longitudinal axis, and a brush portion located on the shaft portion. The brush portion comprises at least one radial projection having a helical form. The protrusion comprises at least one contact zone for contacting a surface. An outer diameter of the helical form formed by the at least one contact zone is tapered at both longitudinal ends of the brush portion such that the outer diameter of the helical form is reduced at the longitudinal ends of the brush portion. The brush portion is formed from a brush portion material and a lubricant agent which is transferred from the at least one contact zone to a surface during use.

  • Publication number: 20250027605
    Abstract: An apparatus for lubricating a surface of a tubular element for a medicament delivery device includes a rotatable drum comprising a tubular element receiving section configured to receive a tubular element to be lubricated. The drum is rotatable about its central axis. The apparatus comprises a device manipulator comprising a device handler at one end of a rod. The device handler is configured to receive a shaft portion of a device, and the rod moves a device through a received tubular element. The device manipulator is rotatable about the central axis of the rotatable drum.
