Abstract: A method of forming a closure member may include: providing a support member with an outer support surface; providing a member including a first member made of electrically conductive material, wherein the first member includes a first tubular sleeve extending along a longitudinal direction between a first top end and a first bottom end; positioning the member on the support member; applying a magnetic field on the member to deform at least a portion of the first tubular sleeve around the support member to form the closure member; and/or removing the formed closure member from the support member for subsequently fitting the formed closure member on a neck of a container or a closure body.

Abstract: A protective tube device can protect a temperature sensor against contact with a fluid, and has a distal end containing the temperature sensor and has an outer wall provided for contact with the fluid, and a proximal end which is connected to the temperature sensor by electric lines and is intended for arrangement outside the fluid, wherein, on the outer wall of the distal end, an elastic membrane closes off a resultantly defined pressure transmission fluid reservoir in a fluid-impermeable manner, the pressure transmission fluid reservoir being connected fluidically by a fluid channel running within the protective tube device to a pressure sensor arranged in the proximal end.
