ABSTRACT:
Presented is a microtube and closure cap assembly in which the closure cap is flexibly tethered to the microtube so that the closure cap may be swung from a microtube-open position to a microtube-closed and sealed position, and the closure cap then rotated through a predetermined arc to lock the closure cap to the microtube in sealed condition. Opening of the microtube from its sealed and locked condition is effected by reversing the procedure, i.e., rotating the closure cap to unlock it from the microtube and then lifting the closure cap from the microtube to break the seal. A lock lug on the microtube and a lock housing on the closure cap that are initially laterally offset when the microtube is sealed by the closure cap are brought into locking interengagement by relative rotation of the closure cap and microtube following sealing of the microtube.
