Abstract:
A process for manufacturing a funnel-shaped protective cap (1) which is adapted to be fitted to an ear canal temperature measurement probe of an infrared radiation thermometer and includes a tubular base body (3) made of plastic material having its one end open and its opposite end closed by a window film (7) transparent to infrared radiation, characterized inthat in a first step at least one aperture (5) is made in a sheet-, film-, web- or plate-shaped base body material (6) to form a perforated base body material (6),covering and immovably joining the perforated base body material (6) at least in the area of the aperture (5) with a window film (7) fabricated from a plastic material transparent to infrared radiation,shaping the composite body into a protective cap (1) having an opening (4) opposite said aperture (5), and, where applicable,processing the protective cap (1) to final dimensions.
