ABSTRACT:
A container for hypodermic syringes which provides a first, tamper-indicating sealed position for containing a sterilized syringe and a seocnd, lockingly closed position for storing and safely disposing of a used syringe is disclosed. The container includes an elongated hollow plastic tube having an integral end wall closing one end. The opposite open end of the tube flares out to form an enlarged cylindrical boss section. A concave plastic cap fits snugly over rear annular beads projecting readially outwards from the rear portion of the outer cylindrical wall of the boss. Ultrasonic welds between the outer circumferential surface of the rear annular beads, and the inner cylindrical surface of the cap are breakable by twisting the cap relative to the tube providing an audible and tactile indication that the container has not previously been opened. The cap has one or more axially disposed resilient tabs, each tab formed between a pair of slots extending axially inwards from the annular end wall of the cap. A larger diameter, front annular bead projecting radially outwards from the front portion of the boss section of the tube lockingly engages a groove in the inner surface of each resilient tab of the cap when the cap is pushed sufficiently far down on a tube, containing a used syringe, permitting the container and enclosed syringe to be safely transported to a disposal site.
