Method and apparatus for removing barrier-type closures from blood collection tubes

摘要

A covered medical specimen container comprises a collection tube having an open upper end defined by a perimetrical rim. A cover is positioned over the open end and removably attached to the rim. A removable cap is positioned over the cover at a location spaced from the rim. Removal of the cover is achieved by exerting a removal force on the cap which the cap transforms into a localized peeling force that progresses around the entire rim.
