Thermometer sheath package for electronic thermometers

Abstract

In a thermometer sheath package, for electronic clinical thermometers, two strips of thermoplastic material are sandwiched between two coated paper cover strips all joined together along a seal line in the shape of a sheath for the probe of the thermometer. The inner two strips are joined together along the seal line by a tear seal to define the sheath for the thermometer probe. The cover strips are joined to the inner strips along the seal line by peelable seals. Perforated lines are defined across the width of the cover strips near the mouth of the sheath to define tabs in the cover strips at the mouth of the sheath. The tabs of the cover strips are sealed to the inner strips in broad flat seals across the width of the cover strips. The seal line defining the sheath and along which all four strips are sealed together extends past the perforated lines and into the area of the broad flat seals. When the sheath is used and an electronic thermometer probe is inserted into the sheath, the portion of the seal line extending past the perforated lines and into the tabs of the cover strips, holds the tabs securely against the handle of the electronic thermometer. After the thermometer has been inserted, the cover strips are peeled away along with the selvage of the inner two strips outside the tear seal line and the cover strips are snapped away from the tabs along the perforated lines.
