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.

Claim 1
Independent Claim
215 words
A thermometer sheath package comprising a pair of inner strips of flexible thermoplastic material, a pair of flexible cover strips sandwiching said inner strips, said strips being sealed together along a seal line to form a tear seal between said inner strips and a peelable seal between said cover strips and said inner strips, said seal line being shaped so that said tear seal in said inner strips defines a thermometer sheath from said inner strips adapted to fit over the probe of an electronic thermometer, said cover strips having weakened lines defined therein extending across said paper strips adjacent to the mouth of said sheath to define tabs in said cover strips adjacent said mouth, said cover strips being sealed to said inner strips in flat seals in areas extending across said paper strips adjacent to said weakened lines and on the opposite side of said weakened lines from the toe of said sheath, said seal line defining the mouth of said sheath extending across said weakened lines and into said flat seal areas whereby said tabs will be pressed against a handle of an inserted electronic thermometer to hold the sheath securely in position on a probe of the electronic thermometer for electronic thermometers with different girths at the mouth of said sheath.

A thermometer sheath package comprising a pair of inner strips of flexible thermoplastic material, a pair of flexible cover strips sandwiching said inner strips, said strips being sealed together along a seal line to form a tear seal between said inner strips and a peelable seal between said cover strips and said inner strips, said seal line being shaped so that said tear seal in said inner strips defines a thermometer sheath from said inner strips adapted to fit over the probe of an electronic thermometer, said cover strips having weakened lines defined therein extending across said paper strips adjacent to the mouth of said sheath to define tabs in said cover strips adjacent said mouth, said cover strips being sealed to said inner strips in flat seals in areas extending across said paper strips adjacent to said weakened lines and on the opposite side of said weakened lines from the toe of said sheath, said seal line defining the mouth of said sheath extending across said weakened lines and into said flat seal areas whereby said tabs will be pressed against a handle of an inserted electronic thermometer to hold the sheath securely in position on a probe of the electronic thermometer for electronic thermometers with different girths at the mouth of said sheath.
Claim 3
Dependent Claim
22 words
A thermometer sheath package, as recited in claim 1, wherein said tear seal line extends into said flat seal areas about 1/16".
Claim 4
Dependent Claim
58 words
A thermometer sheath package, as recited in claim 1, wherein said tear seal line is shaped to provide parallel sides to the said sheath near said toe of said sheath and curves outwardly from a point on said sheath about midway between said toe and said mouth of said sheath to define a flared opening for said sheath.
