Image Number 2 for United States Patent #4062239.
A probe cover incorporating an inner sheath with a probe end engagement section. The section comprises a reduced width of the inner sheath adjacent the end opposite that into which the temperature probe is inserted. The reduced width section is produced by a yieldable bonding of the layers of the sheath together with a graduated bond strength so that with a combination of bond separation and material stretch good contact and retention of the probe end is insured. A tapered welding head in association with a resilient platen is utilized to obtain the graduated weld section. When the temperature probe is removed after use the inner sheath is turned inside-out so that the contamination of the inner sheath is contained inside the inverted sheath and cannot contact the user's hands.
