Abstract
A sanitary protective cover or sheath for the ear canal probe of a tympanic thermometer has a generally tubular body portion and an infrared transparent membrane attached to and sealing the forward end of the tubular body portion. While the tubular body portion is being injection molded of a plastic material, a film of a similar plastic material is mated to the forward end of the tubular body portion. A portion of the film defining the membrane is thus severed from the film and thermally bonded to the tubular body portion.
