ABSTRACT:
A liquid aspiration device comprises an aspiration tube that slideably engages an opening in a cap such that a head on the end of the aspiration tube is moveable with respect to the opening in the cap. A tube cover is positioned between the opening in the cap and the head of the tube. The tube cover is operable to collapse into the cap when the head is moved into the cap. When the head and the tube cover are moved into the cap they are shielded from potential contamination that may occur when the aspiration device is moved from one container to the next. A lock is positioned in the cap. The lock is operable to move between an engaged position where the head may be retained within the cap and a disengaged position where the head is free to pass into or out of the cap.
