发明名称 Disposable thermometer sheath package
摘要 A disposable thermometer sheath package contains a sheath to provide a sterile barrier during temperature taking with a clinical thermometer. The sheath package comprises inner strips in which the sheath is formed by a tear seal and outer cover strips. All four strips of the sheath are sealed together in the tab portion thereof along the edges of a tab portion to make the tab portion into a pocket leading to the mouth of the sheath. Additional flat seals are formed between all four strips within the tear seal to provide a restriction within the sheath in order to cause the sheath to turn inside out upon a thermometer being withdrawn. A die is provided to simultaneously make the tear seal and the flat seals. The die surfaces of the flat seal forming portions of the die are offset from the die surface of the tear seal forming portion to permit the tear seal forming portion to sink sufficiently far into the sandwich of strips of the sheath package to properly form the tear seal.
